Abstract: DYNAMIC BUFFER CIRCUIT            Abstract of the Disclosure An input data buffer circuit, which includes six field effect transistors, is utilized in combination with a dynamic memory in order to widen the operating margins of the memory system.  The buffer circuit is fabricated on the same integrated circuit chip as the memory, so that the electrical characteristics of the transistors of the buffer circuit and of the memory will be essentially identical.  The levels of the output signals of the buffer circuit are relatively independent of random variations in levels of input signals because the levels of the output signals are primarily a function of the magnitude of the common power supply used by the buffer circuit and the memory, the electrical characteristics of the transistors of the buffer circuit and the memory, and the internal and external signals utilized by the memory.

Abstract: TRANSPORATION SYSTEM WITH BRAKE CONTROL AND     COMBINED BRAKE AND FIELD POWER SUPPLY      ABSTRACT OF THE DISCLOSURE A solid-state static power converter changes a first current frequency to a second current frequency such as, for example, A.C. to D.C., D.C. to A.C., or A.C. of one frequency to A.C. of another frequency such as in a cyclo-converter or the like, and operates a motor to drive a traction sheave to control the movement of an elevator car in response to an error signal derived by the selective summation of a speed signal from a tachometer and a vehicle speed command signal.  In one embodiment, a combined solid-state static power converter receive a three-phase A.C. input and directly supplies direct current to a field circuit of the motor in response to the operation of a field gating control circuit and also directly supplies direct current to a brake operating solenoid circuit controlling a friction braking element selectively coupled to an output shaft of the motor.  The combined field and brake static power converter includes three controlled rectifying devices and three diodes connected to selectively supply half-wave rectified uni-directional power to the field circuit while a fourth controlled rectifier is connected to one of the phases and cooperates with one or more of the diodes utilized in the field current conversion together with one field output lead to supply uni-direction energy to the brake solenoid. The brake gating control includes a summing circuit receiving an alternating phase reference signal from the source through a lag filter circuit, a disable signal from the source through lead and lag filtering circuits, a constant reference signal, and a brake energy command signal supplied from a second summing circuit.  The second summing circuit receives a brake lifting command signal in response to the supervisory control and a brake energy sensed feedback signal.

Abstract: Abstract of the Disclosure Siloxane foams can be prepared by mixing an organohydrogensiloxane, a hydroxylated organosiloxane and a platinum catalyst in amounts such that the ratio of silicon-bonded hydrogen atoms to silicon-bonded hydroxyl radicals is in the range from 2.5/1 to 7/1 and thereafter allowing the mixture to foam.  The amount of open-cell structure in the foam can be increased by having present in the mixture an organomonohydrogensiloxane such that the molar ratio of silicon-bonded hydrogen atoms from the organo-hydrogensiloxane to silicon-bonded hydrogen atoms from the organomonohydrogensiloxane is from 0.4/1 to 2/1.  The siloxane foams can be made to have an increased fire retardant property by adding 0.01 to 2 parts by weight carbon black based on the weight of the total composition.  Siloxane foams are also prepared by mixing an organohydrogensiloxane, an organo-monohydrogensiloxane, a hydroxylated organosiloxane, a vinyl containing triorganosiloxy endblocked polydiorganosiloxane and a platinum catalyst.  These foams can be used for cushioning, in acoustical applications and protective filling or coating applications and especially applications wherein fire retarding is important.

Abstract: Abstract of the Disclosure A multiple-frequency decoder which measures the two-tone output from a multiple-frequency dial type telephone and identifies what number was dialed.  A unique binary code is produced as a timed output for each number dialed.  In addition, the decoder has provision for detecting and providing as a separate output a unique binary output word whenever a preselected transfer digit, e.g. a "1", "2" or "3" is dialed.  With this additional output data, transfer relays can be operated.  The decoder inputs are derived from high and low pass filters.  The decoder differentiates between valid multiple-frequency tones and extraneous noise, such as voice signals, completely digitally, as follows: once the digital measurement of one cycle of each of the multiple incoming frequencies is made, the combination of all frequency measurements is stored as a k-bit binary word. In order for an incoming signal to be considered valid, the same k-bit binary word must occur n consecutive times, where n is preselected based on the degree of noise immunity required.

Channel means are attached to the housing for receiving and guiding a partial loop of excess cable and for allowing movement of that partial loop due to a change in size of the partial loop from a point in which an intermediate part of the partial loop is in contact with the other side of the drive wheel means to a point in which the intermediate part is spaced a substantial distance from the drive wheel means. In this way, the channel means comprises the sole support for the partial loop, the partial loop of excess cable extends from the point at which the cable departs contact with the drive wheel means to a point at which the cable departs the channel means.  The cable conveyor  so provided is more economical to manufacture and is more trouble-free in its performance than prior art devices, and is shut down if the cable becomes too long or is broken.

Abstract: TITLE           SEALING PLUNGER FOR CARTRIDGE   ABSTRACT           A cartridge plunger has a generally cup-shaped body molded of a relatively rigid resin material, and a seal material is joined to the body and molded of a substantially softer and more resilient resin material.  The body has an annular wall closely spaced from the inner surface of the cartridge, and the seal material extends around the outside of the annular wall which presses the seal material tightly against the inner surface of the cartridge when the plunger is in the cartridge.  The seal material can also extend rearwardly of the plunger body and around the rearward edge of the cartridge for an additional seal when the plunger is initially seated in the cartridge.  The softness and conformability of the sealing material forms a better sealing engagement with the cartridge to protect the contents from moisture and air.

Abstract: ABSTRACT OF THE DISCLOSURE           A fast conched candy coating is provided herein.  The coating is prepared by providing a mixture of fat and sugar, optionally with milk solids, emulsifiers, flavoring, cocoa or cocoa butter, heating the mixture to a temperature above the melting point of the fat but below 150°F, and conching the mixture in a high speed shearing and mixing de-vice.  The mechanical energy imparted during the shearing and mixing raise the conching temperature to between 150°F and 250°F in less than 30 seconds.  The coating can thus be produced in a fraction of the time necessary for producing a conventionally conched compound coating for candies.
