A device for holding skis and other elongated articles comprises a pair of holding members each of which includes a shaft on which there are keyed at a distance from each other two rollers of a moderately yielding material, with rollers of one holding member at a short distance from those of another holding member, each of the holding members being supported by an arm of springy material, the arms being adapted to be affixed to a stationary member. A preferred embodiment of the device includes a...

An apparatus and method are shown for eliminating mistakes during plasmapheresis procedures in returning red blood cells to a correct donor. In the procedure, a portion of the return blood flow line is rendered inoperative by a lock device. A key, unique to the donor, is attached to the blood collection bag prior to the centrifuging operation which separates the blood into plasma and red blood cells. After the centrifuge operation, flow between the collection bag and the donor can only be establ...

A high voltage color switch for a beam penetration CRT is well suited to generating a color write in one or more random colors during the retrace interval of a TV raster scan, or the like. The scanning period of the TV raster is in the baseline color for maximum resolution and brightness. A driver connected to the high voltage transformer includes a low voltage power supply which has one portion controlled by a switch. During the color write period the switch is closed so that the driver can pro...

Temperature monitoring of electrically conductive wire during heating in which the current in the wire in the heating zone is measured and the voltage at the downstream end portion of the zone is measured, signals corresponding to the measured values then being combined to produce a resultant signal corresponding to the resistance of the wire at the downstream end portion of the heating zone. The resistance value corresponds to the temperature of the heated wire. Apparatus includes current and v...

A carrier for supporting extended metal workpieces during electrolytic finishing treatments comprises a flight bar supporting at least two dependent spline members, both the flight bar and the spline members being electrically connected to the workpieces supported by the carrier. Each spline has two or more support arms for the workpieces and a clamp bar, carrying spaced clamp arms arranged at the same vertical interval as the support arms, is arranged for vertical movement in relation to each s...

The invention discloses processes for preparing matched sizes of electric furnace feed materials. With the matched sizes, components of the feed mixture do not separate inside the furnace and this decreases the electric energy for smelting. Preparation of matched sizes of materials is made possible by low-temperature agglomeration followed by drying to indurate the agglomerates. Fuel requirements for induration are substantially reduced, and environmental problems associated with high-temperatur...

A device for use in monitoring cervical dilatation during labor. The device comprises an elongated member having a longitudinal axis, the member being adapted to be positioned between a fetal presenting part and a cervix; and means for measuring the recession of the cervix with cervical dilatation from the elongated member and along the longitudinal axis thereof. Also provided are systems and methods of monitoring cervical dilatation during labor. An elongated member having a longitudinal axis i...

A breathable, laminated, sanitary barrier is provided for use during cardiopulmonary resuscitation (CPR). The laminate comprises a sheet of expanded, porous polytetrafluoroethylene bonded to a substrate material. When placed over a patient's nose and mouth, the barrier enables the CPR practitioner to perform his/her mouth-to-mouth rescue attempt with substantially no reduction in air flow and eliminates direct mouth-to-mouth contact while substantially preventing the transfer of aerosols, bacter...

A technique for pre-programming a reproduction machine for a plurality of complex jobs involving a variety of machine features and requirements using the operator console and touch sensitive screen display while the machine is in the print state or still in the process of completing a previous job. In particular, while the machine is in operation, touching a Program Ahead file on the screen, displays a simulation of a plurality of pre-programming slots or folders. By touching one of the pre-prog...

An aroma-generating flavor composition is described which will generate desirable aromas when a food and/or a package is subjected to microwave radiation. The composition comprises an aroma-generating material which is either a sugar alone or in combination with an amino acid source. Also, the composition contains an effective amount of a microwave susceptible material in conductive heat transfer relationship with the sugar and/or amino acid source, the microwave susceptible material when irradi...
