Title: Spool valves
Inventor: GREENFIELD GORDON WILLIAM
IPC: F16K31/40
Filed: 1969-12-10
Abstract: 1,237,530. Valves. TEMPLE INSTRUMENTS Ltd. 10 Dec., 1969, No. 60204/69. Heading F2V. A valve for controlling a pneumatic system comprises a spool 19 having opposite ends of equal effective area, a first passage 63, 67 extending through the spool between the ends thereof, an inlet 22 for line pressure, a second passage 65 extending between the first passage and the inlet, a spigot 33 received in the first passage with clearance 64 and communicating with a vent 31, the spool having first and second equilibrium positions adjacent the first and second ends of the body and the clearance 64 being so arranged that when the vent is opened the pressure at the lower end 76 of the spool drops more rapidly than the pressure at the upper end of the spool and the spool moves downwardly to its second equilibrium position, and means 49 to restore the spool to its first position. The movement of the spool connects a service port 45 carried by a rotatable ring 38 with the inlet port 22 or with an exhaust port 46. The valve may form part of a manifold block 10 and be connected to a manifold supply line through a port 14. Connection of the passage 63 to the vent 31 is controlled by a spring-loaded, solenoid-operated plunger 29 and the means to restore the spool to its first position consists of a piston 49 lifted by applying pilot pressure to a port 55.

Patent GB-1319163-A (GB)
Title: Time division multiplex highway switching arrangement
IPC: H04Q11/04
Filed: 1970-12-29
Abstract: 1319163 Automatic exchange systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS and SOC LANNIONNAISE D'ELECTRONIQUE 29 Dec 1970 [29 Dec 1969] 61683/70 Addition to 1286909 Heading H4K The three-stage time division-multiplex highway switching network of the parent Specification 1,286,909 is expanded by placing two networks side-by-side and having each outlet of the first stage switches of each network give access to a corresponding intermediate switch in the other network as well as to the corresponding intermediate switch in its own network, the intermediate switches of each network giving access to only the third stage of their own network. The trunking between switches of parallel networks R1 and R2 is shown in Fig. 1. The incoming highways of a switch, such as LRE1 to LRE32 of a first stage switch, Fig. 2, set multiplex channel frames on registers REE1 to REE32, the total array of channels of all highways incoming to the switch being set up in parallel on a common register MTE1. Control MCE1, comprising a circulating store selectively addresses the common register MTE 1 to read out the 8-bit codes of appropriate incoming channels in the time slots of appropriate channels on desired outgoing highways. To cope with the double number of inlets of an intermediate switch, as compared with first and third stage switches, the incoming registers REI1 to REI32 of network R1 work to a common register MTI1 while incoming registers KEI<SP>1</SP>1 to REI<SP>1</SP>32 work to a common register MTI<SP>1</SP>1. The address capability of the control MCI1 is augmented to the extent of one bit per channel in an auxiliary section EB such bits having the effect of distinguishing own-network and other-network incoming highways. A speech connection requires two paths across the network for each direction of speech. Third stage switches may have additional multiplex highway outlets for the connection of tones, each channel of the additional multiplex being pulse code modulated to represent a particular voice-frequency signal.

Title: Method of Producing Typographical Data
IPC: B41J2/485
Filed: 1979-05-25
Abstract: A method of producing typographical data defining the characters used in an ideographic language, uses a store containing sets of coded signals, each defining the strokes of one of a set of character components or radicals from which the characters of the language can be formed. The store also contains data defining a set of basic patterns for the arrangement of the components within a character area. A character selector, conveniently a keyboard and associated encoding circuitry, is operated to generate an identifying signal which is unique to the selected character and which identifies the appropriate pattern for that character. The identifying signal is processed to obtain from the store typographical data corresponding to the various coded signals defining the strokes of all the components forming the selected character, and their positions within the character area according to the associated pattern. <IMAGE>

Title: Device for regulating the brightness of fluorescent lamps
IPC: H05B41/392
Filed: 1979-07-30
Abstract: A brightness regulating device (1) for a fluorescent lamp (8) contains a semi-conductor switch (11) connected in series with the lamp. The semiconductor switch (11) is phase-shift controlled by a device (12). An incandescent lamp (16) is connected in shunt with the semiconductor switch (11), or parallel to a series connection of the semiconductor switch (11) and an interference filter (13), (14), (15). The lamp (16) maintains a small glow discharge current in the fluorescent lamp (8) when the switch (11) is open. By this means the brightness regulation range can be broadened in the direction of shorter switching times. In addition, electrical and acoustic interference and noise phenomena at the filters and ballast are reduced. <IMAGE>

Title: Digital subscriber loop
IPC: H04Q11/04
Filed: 1979-08-14
Abstract: In a fully digital telecommunication system such as a multi-exchange system of the integrated Systems Digital Network type, the subscriber's sets are each connected to the exchange via a full- duplex digital loop. Digitally-encoded speech, data and other digital services are carried on the loop alternately with in-band signalling and supervisory messages and framing data, the messages conveying this being suitably formatted with start and end flag codes. The formatting is effected via a special codec 17 which is connected to the line circuit 10 when such traffic is being handled. Speech from/to a hardset 3 is conveyed to or from the line circuit 10 via a PCM codec 8, and data from a data interface 11 is suitably formatted to go direct to or from the line circuit 10. The line circuit arrangements continuously monitor the loop for such messages so that when one is detected it can be dealt with. <IMAGE>

Title: Dispensing detergents into washing machines
IPC: A47L15/44
Filed: 1979-11-12
Abstract: A washing machine such as dishwashing machine 10 includes a dispenser 20 for introducing detergent into the machine.
