Abstract: ABSTRACT     The invention disclosed pertains to time division switching systems used in digital telephone switching and in data communication.  In prior, systems, the maximum number of simultaneous connections between pairs of subscribers is half the number of time slots in a communication path.  The present invention permits the degree of multiplexing to be equal to the time slots in a communication path.  It involves the use of a code coveting cir-cuit for receiving two digital signals from two line circuits participating in one communication and for producing a third digital signal indicating the relationship between the two digital signals.  A common bus distributes the third signal to the respective line circuits.  A control memory stores many address pairs for the two line circuits.  Control circuitry  allots one time slot to the two line circuits so that information is changed periodically between the two line circuits by an address pair obtained periodically from the memory.  A code inverse-converting circuit in each line receives the third digital signal and the digital signal from its own line to reproduce the digital signal of the other line.

Abstract: A B S T R A C T   A liquid supply system for a hydrostatic bearing is provided with an accumulator for maintaining a required liquid pressure in the bearing during its slow-down at times of pump failure.  The accumulator has a movable piston and a pressurized gas system for maintaining a sufficient liquid pressure in the accumulator.  A portion of the pressure liquid for the bearing is led through a pressure generating member, such as a metering unit, which provides liquid under a pressure higher than the maximum liquid pressure in the bearing. The accumulator communicates with this higher pressure liquid.  A part of the higher pressure liquid flows to the bearing via a constant flow valve which is in fluid communication with the accumulator.  A return condiit in fluid communication with the accumulator has a one-way valve leading to a lower pressure position.  The one-way valve opens when the liquid pressure upstream corresponds to the higher pressure so that the remainder of the portion of the pressure liquid flows to the lower pressure position.

Abstract: Abstract of the Disclosure A video recording and reproducing apparatus utilizes a specialized head assembly which is arranged to be driven in a radial direction relative to a rotating magnetic recording disc.  A spiral track is recorded on the disc and the specialized head assembly employs two discrete indi-vidual heads which are proximately aligned.  The signals produced by each head are utilized in producing the final output signal.  During playback, "scene motion speed" depends upon the speed at which the bead is moved in a radial direc-tion relative to the recorded disc and on the manner in which the output signals from the two heads are operated on.

Abstract: ABSTRACT OF THE DISCLOSURE:            For the purpose of controlling the electrical energy fed to an electrical gas discharge lamp, without an incandescent cathode, as a function of a d.c. control voltage, there is provided a circuit arrangement by means of which the ignition timing or angle of a triac may be varied within each alternating-voltage half-wave.  In order to prevent the lamp from unwanted extinction when adjusted to minimal brightness, an additional circuit arrangement is provided, ensuring a given minimal intensity of the current flowing through the said lamp, regardless of the level of the said d.c. control voltage.          The additional  circuit arrangement comprises  a current transformer and a rectifier arrangement for producing a regulating voltage depending upon the intensity of the lamp current and controlling an electronically variable resistance.          The latter influences the critical ignition-angle-control voltage whenever the intensity of the lamp current drops below a permissible minimal value, in such a manner that any further decrease in current intensity is automatically counteracted.          The device is intended, for example, for controlling the bright-ness of lighting units, comprising mercury-vapour lamps or high-pressure sodium-vapour lamps, used for interiors,highways and tunnels.

Abstract: ABSTRACT OF THE DISCLOSURE         A system and method for conditioning the air supplied to a paint spray booth enclosure in which the air is dehumidified during summertime operation by liquid ab-sorption of the water vapor from the incoming air.  The cir-culated absorption liquid is cooled to eliminate the heat developed by the dehumidification and a portion of the heat rejected into the exhaust air from the paint spray booth.          In one version, heat pump units are used to extract the re-maining portion of the rejected heat with the extracted heat transferred to a regenerator heat exchanger utilized to pro-vide heat to reconcentrate the liquid absorption solution.  The heat pumps are also utilized to cool the supply air and the heat so extracted is also used to heat the absorption liquid during regeneration.  During wintertime operation, the heat pump units extract heat from the exhaust air of the paint supply booth of the heat exchanger arrangement and transfer it into a heat transfer loop utilized to preheat the incoming air as well as to heat a dilute solution of the absorption liquid used to humidify the air.  In another version, the cooled exhaust  air from the spray booth directly cools the absorption liquid and the incoming ambient air by an air-to-liquid heat exchanger, and a secondary waste heat source is utilized in regeneration of the absorption liquid.

Abstract: ABSTRACT OF THE DISCLOSURE     A snap disc operator pressure switch is disclosed in which a thin flexible diaphragm is positioned adjacent to the disc to isolate the pressure chamber from the disc chamber and to transmit the pressure forces directly to the surface of the disc.  The disc is positioned in a disc seat and is held therein by the diaphragm.  The calibration of the disc is not adversely affected because it is not necessary to provide a seal directly with the disc.  The disc seat member is shaped to support the disc against overpressure and to provide a guide for the switch bumper.  When higher operating pressures are required, two discs are positioned in the disc seat at face-to-face adjacency and the device operates at a pressure substantially equal to the sum of the calibration pressures of the discs.  In another embodiment, the movable arm of the switch is biased closed and is moved to an open position by a spring-biased operator.  In such embodiment, the maximum stress applied to the movable arm is determined by the spring force on the operator, so overstressing and fatigue failures of the arm are sub-stantially eliminated.

Abstract: Abstract of the Disclosure A pressure sensitive indicating device  (10)  is disclosed.  The device (10) includes a housing (12) defin-ing a primary chamber (26).  The primary chamber (26) has a first end (28), a second end (30) and an axis (32) extend-ing between the two ends.  A movable member (34, 62) is supported in the primary chamber (26) for motion therein. The movable member has a first side disposed in the primary chamber (26) and a second side disposed outside the primary chamber (26).  A first aperture mechanism (118) provides fluid communication between the primary chamber (26) and the  exterior of the housing  (12).  A coil  spring  (84) biases the movable member toward the  first end of  the primary  chamber.   An  indicator mechanism  (86,  208)  is coupled to the movable member for motion therewith to indi-cate the position of the movable member within the primary chamber in response to fluid pressure applied to at least one of the sides of the movable member.  The indicator means is visible from a viewing face (14) of the housing. The viewing face is viewed transversely to the primary chamber axis (32).  A releasable locking means (152, 226) locks  the  movable  member  and  the  indicator  mechanism against the biasing force of the spring (84) at a plurality of positions along the path of travel of the movable member toward the second end of the primary chamber.  A release mechanism (168, 220) is provided for releasing the locking mechanism to allow the movable member to move toward the first end of the primary chamber under the biasing force of the biasing means.  The release mechanism extends generally transverse  to  the  axis  of  the  primary chamber and is actuatable from the viewing face of the housing.
