A device for injecting a gas into bulk material stored within a vessel to enhance the flow characteristics of the material. The device includes a housing to be mounted within an opening in the wall of the vessel and having a connection to a source of gas under pressure. The housing supports a porous metal filter element which permits the flow of gas into the material confined within the vessel but prevents the escape of the material into the pressurized gas system. The housing is designed so tha...

A stored program data processing system including a logic control arrangement including a particular arithmetic and logic unit controlled from instruction translating means responsive to instructions stored in a memory for effecting supervision and control over a telephone exchange in accordance with timed sequences provided by a cycle control arrangement.

Disclosed is a unique stored program format generator for sequentially sampling a plurality of data channels at various sampling rates. The format generator accomplishes addressing of subcommutated data channels with the use of a single counter whose contents are combined with stored masking functions corresponding to different subcommutation factors. The combined word acts as an address word to access the generator memory at the location storing the address of the desired subcommutated data cha...

A stored energy gyro wherein pressurized air is contained in a chamber surrounded by the gyro rotor. Rotor speed is obtained by rupturing a pressure seal in the chamber, with the escaping gas being directed through vanes in the rotor for providing the necessary spin force.

A signalling circuit for telephone sets utilizes ringing signals applied thereto to enable a control device, such as a transistor, to pass energy through a signalling device, such as a ringer, thereby actuating it during the ringing cycle. When used in conjunction with one telephone line, the energy is supplied from an energy storage means in the circuit, such as a capacitor, which receives and stores the charge from the telephone line. When used in conjunction with a plurality of telephone line...

A method of stabilizing the energy stored by a reactive storage device, and the apparatus therefor, are provided in accordance with the teachings of the present invention. The amount of energy depleted from said reactive storage device by the inherent leakage characteristics thereof is determined and additional energy is supplied to said reactive storage device accordingly. A recurrent pulse signal having a period dependent upon the energy stored by the reactive storage device is generated. A ch...

A stored logic character recognition system is disclosed that includes a read-only memory in which is stored a set of functions, the evaluation of which leads to the classification of a given binary pattern. A measurement register performs logical operations on the pattern data to generate a plurality of measurement words. An identification sequence for each character is begun by fetching a predetermined word from the read-only memory to a control-word register. Succeeding words are then fetched...

The weight of a high pressure storage vessel 20 for an oxidant used to oxidize fuel in a combustor 12 which in turn provides gases of combustion to a turbine wheel 10 may be minimized by providing an incendiary device 32 within the vessel 20 which is triggered by a sensor 34, 36 in response to some sensed characteristic of the oxidant within the vessel 20 to increase the pressure within the vessel 20 and to drive the oxidant to the combustor 12.

A computer for executing instructions grouped in fixed length macroinstructions having a bulk memory for storing the macroinstructions and data, and an operational delay line memory divisable into a plurality of zones for storing the macroinstruction presently under execution and data being operated upon. Means are provided for transferring macroinstructions and data between the two memories. The macroinstruction under execution can select one of two macroinstructions from the bulk memory to be ...

A garment separator suitable for use with expensive or fragile garments made of materials such as fur or silk includes a thin, flexible, smooth-sided, flat, integrally-formed separator element supportable from its top by an integral transverse extension which is readily locatable between adjacent garments supported on a common support rod by a clamping element that brackets the transverse extension of the separator element and grasps the support rod to prevent unintended relative movement thereb...
