A heavy-duty moving system including a sled, two sets of removable heavy-duty caster wheels (FIG. 1) and a lever arm assembly (FIG. 1A) for moving heavy equipment, for example, the "XEROX" copy machines of the 2400 series. The sled is slid under the machine (FIG. 3) and then raised at one end by the lever assembly (FIG. 4), one set of caster wheels then being laterally inserted and locked into the sled (FIG. 5). The opposite end of the sled is raised and the second set of caster wheels inserted ...

This invention relates to a founding process involving metal alloy compositions which upon solidification precipitate at least two distinct phases simultaneously. The metallurgical structure of castings resulting from this founding process is altered by subjecting the solidifying metal to a mild angular or rotative acceleration. The direction of this angular acceleration is periodically reversed to avoid high rotational speeds. This results in an angular or rotative oscillation.

The roller body to be coated is enveloped by a material layer which thereafter is enveloped with another surface layer, the surface layer being brought into fused condition, for instance, by welding and when cooling it causes the material layer to contract around the roller body, after which the surface layer can be removed.

A method of knitting a sleeved garment on a knitting machine, the method including the steps of knitting a shoulder portion of each sleeve, in the direction towards the upper end of the sleeve, in reciprocatory manner on both beds of a pair of opposed beds of the machine so that pieces of the shoulder region on the two beds are joined together at an edge of the sleeve which is outermost in the finished garment, knitting the body of the garment commencing at the lower end and knitting front and r...

In coating a coating composition on a web by a bridge of the coating composition between a coating applicator and the web, a gas blowing slot is formed at the side of the coating applicator into which the web enters to remove air or dust carried on the surface of the entering support and to provide a reduced pressure space at the back side of the bridge so that the bridge is maintained stable when the coating speed is increased.

A new method and apparatus for filling a vehicle gasoline tank and automatically recording the identity of the vehicle and the amount of gasoline added is disclosed. These systems are further useful in a method for periodically maintaining a group of vehicles which are parked for a relatively long time as in a daily parking lot. The vehicles can thus be maintained with gas, oil, etc., without the necessity for the owner or driver being present.

A prosthetic denture and method of manufacture and self-fitting comprising a rigid U-shaped frame bonded into notches in bases of a set of artificial teeth; a deformable metal mesh forming a plate structure for said set of teeth; a soft elastomeric material encapsulating said mesh and bonding it to said set of teeth to form a deformable plate structure, whereby a self-fitting method for installing said set of teeth comprises the coating of said plate structure with uncured elastomeric material, ...

A welding method used in electric arc welding wherein a consumable wire core electrode is fed by a nozzle onto a workpiece at a welding station. The nozzle moves relative to the workpiece at a changeable speed including intermittent motion so as to provided an agitating action to the weld metal, the intermittent motion being in the form of oscillations at between 0.2 to 4 Hz and small amplitude along the direction of the weld seam.

An antenna system arranged at the end of the runway radiates Tacan pulses, and an antenna system arranged beside the runway radiates additional information in the form of pulses having specific time relationships with the Tacan pulse-pair. The additional information is evaluated by means of a Tacan receiver whose video stage is followed by a decoder for the additional information.

A rangefinder and a rangefinding method, the rangefinder being combined with a motion picture camera and comprising a transparent mirror mounted on the camera in an upwardly and forwardly inclinded position across the line of sight from an operator behind the camera to an object in front of the camera for viewing of the object through the mirror while the reflection of a second object a selected distance from the mirror is reflected therefrom in superimposed relation with the first object. This ...
