Abstract: ABSTRACT At the sending end randomly generated binary code numbers and program identification numbers are inserted into the television signal. The code numbers are also processed in accordance with a program assignment code to change or leave unchanged a predetermined characteristic of the television signal. At the receiving end the program identification numbers address a random access memory and read out program assign-ment signals stored therein. The program assignment signals control logic circuits which process the received code numbers in correspondence to the pro-cessing at the transmitter. The program assignment numbers must be updated periodically by a central computer-to-decoder transmission for proper decoding to take place. The program identification numbers are stored in the same memory for billing purposes only if the subscriber accepts the program. Since updating of the program assignment numbers does not take place until all previously stored program identification numbers have been transmitted to the computer along with a customer identification number for billing, initiation of communication between decoder and computer can be subscriber controlled. -1-

Abstract: ABSTRACT OF THE INVENTION         Metallic glasses having high permeability, low magneto-striction, low ac core loss and high thermal stability are disclosed.  In contrast to the prior art in which one, or at most two, of these properties are attained in one metallic glass, all those outstanding properties are achieved in a single metallic glass selected from one of the compositions of the invention. The metallic glasses consist essentially of about 63 to 83 atom percent of at least one metal selected from the group consisting of iron and cobalt, from 0 to about 60% of which metal may be replaced with nickel, about 2 to 12 atom percent of at least one element selected from the group consisting of molybdenum, tungsten, niobium and titanium, and about 15 to 25 atom percent of at least one metalloid element selected from the group consisting of boron, phosphorus and carbon plus incidental impurities.  In summary, the metallic glasses have a combination of high permeability, low saturation magnetostriction, low ac core loss and high crystallization temperature and are useful as tape heads, relay cores, transformers and the like.

Abstract: Abstract of the Disclosure A programming cam indexing mechanism in which a rotatable programming cam, provided with a peripheral traction surface and a concentric inwardly facing track having one or more notches therein to define indexed programming positions, is rotatably driven by a capstan coupled with a drive shaft, the capstan being supported by a latch member pivotal on the drive shaft axis.  The latch member is integrally formed to define a follower bracket and tab engageable with the inwardly facing track surface on the programming cam to hold the capstan in engagement with the peripheral traction surface thereof but to allow the capstan to swing away from driving engagement with the traction surface when the follower bracket tab drops into the positioning notches.  A spring biasing means is provided by which the follower bracket tab is moved into the notches to latch the programming cam in any one of the indexed positions.  Movement out of the notches is effected by solenoid activation.

Abstract: GATE VALVE HAVING A SINGLE FLOATING SEAT     AND A FIXED SEAT          Abstract of the Disclosure A gate valve has a metal housing with upstream and downstream facing annular recesses surrounding the bore and upstream and downstream seat ring members mounted in the recesses.  The upstream seat ring member is mounted to float axially relative to the bore, and has an annular deformable sealing member of consumable material extending beyond the sealing face to contact the gate.  An O-ring in the upstream recess behind the seat member urges the seat member in the downstream direction and forms a seal therearound in the upstream recess.  The downstream seat ring member is rigidly mounted in the downstream recess in an interference fit which provides metal-to-metal sealing with the housing.  An annular deformable sealing member of consumable material extends be-yond the downstream seat sealing face to contact the gate.          Upon assembly of the valve a slight interference is produced between the gate and the annular sealing members.  The consu-mable material is at least partially consumed at high tempe-ratures so that when the gate is in the closed position it is urged downstream by fluid pressure into metal-to-metal sealing contact with the downstream seat member.

Abstract: ABSTRACT OF THE DISCLOSURE   A process for removing acid gases such as CO2 and H2S from gas streams using an aqueous alkaline scrubbing solution which is circulated between an absorption and regeneration stage wherein the stripping steam for regeneration is derived at least partly from the hot feed gas to be purified. The thermal efficiency of the process is substantially improved by first heat-exchanging the hot feed gas with the scrubbing solution to raise stripping steam and then heat-exchanging the hot feed gas with water (which is pre-ferably condensate water produced in the scrubbing process) in a second heat exchanger operating under reduced pressure, thus recovering additional low-level heat from the feed gas and producing low-pressure steam which is com-pressed and then utilized as additional stripping steam.  In a preferred embodiment, additional low-pressure steam is generated by also flashing off low-pressure steam from the regenerated scrubbing solution and compressing this steam together with the steam produced in the second heat exchanger for use as stripping steam.

Abstract: Abstract of the Disclosure Pressure medium operated control system for a rock drill is described, for preventing the drill steel form getting stuck and for releasing the drill steel if stuck.  The system comprises a striking apparatus, a rotation motor and a feed motor with con-trol valves and sources for pressure medium and, at the striking end of the drill steel, a shank adapter which can be brought into striking contact with the striking piston by means of a shank cylinder and thereto connected pressure medium source, also during the return movement of the drill.  Pressure medium is fed into the said shank cylinder through a pressure controlled direc-tional control valve which is controlled through the pressure line or the rotation speed of the rotation motor.  Reversing of the feed motor from feed of the rock drill into its return movement is caused to take place substantially at the same pressure value of the rotation circuit or at the same rotation speed at which the said directional control valve starts to let pressure medium into the shank cylinder.

Abstract: SINGLE INJECTOR, SINGLE POINT FUEL        INJECTION SYSTEM     ABSTRACT         A flow regulating device for use in a single-point control electronic fuel injection system.  The flow regulating device receives a discrete, pressurized fuel pulse or charge from a fuel injector and extends its time duration over the charge cycle period to approxi-mate a continuous flow.  The extended fuel charge is provided to an atomizer for mixture with air preparatory to being drawn into an engine intake manifold.  In one embodiment of the invention, the flow regulating device includes a constant pressure valve together with a restricted flow passage.  The pressure setting of the valve is below the pressure at which the discrete fuel charge is emitted from the injector, and the restricted passage has an orifice dimension smaller than that of the injector nozzle. In another embodiment of the inven-tion, the flow regulating device takes the form of a pair of parallel connected constant pressure valves together with restricted flow passages.  One constant pressure valve has a first pressure setting below the pressure in which the discrete fuel charge is emitted from the injec-tor.  The other constant pressure valve has a relatively higher pressure setting, but below that of the injector. The pair of constant pressure valves and passages co-operatively function to extend fuel charge duration in both high and low engine operating speeds.
