Abstract: 1275437 Partition wall elements; doors and sills W J NAVARRE 27 Aug 1969 [30 Aug 1968] 42570/69 Headings E1J and E1W. A dismountable partition wall comprises an elongate channel section member 12 secured to a floor and a downwardly directed channel section member 26 secured to a ceiling overlying the floor channel. Each of the channel members have a series of longitudinally spaced opposed pairs of tabs 24 struck out and projecting from the channels such that the web portion 36 of vertical H-section framing members 34 is held between the pairs of tabs 24. Panels 46 are fitted to the framing members by first sliding the top of the panel into the space 48 formed by flanges 26, 32 of the channel member 26 and allowing the panel to drop into flanges 22 on the lower channel member 12. Edge members 50 snap over the vertical edges of the panels 46 and hold them against the resilient flanges 42 of the H-section members 34. A cover 54 clips on the edges between two panels forming a service duct. A vertical channel section member (58) Fig. 3 (not shown) may clip onto the vertical H- sections 34 to form a door jamb held in place against the section 34 by an expanding screw and nut arrangement. Horizontally extending H-section members may include a similar arrangement to fix a window sill (72) Fig. 4 (not shown).

Title: Braking regulator
IPC: B60T8/18
Filed: 1974-10-03
Abstract: 1436308 Braking pressure regulation SOC ANON DBA 3 Oct 1974 [18 Oct 1973] 42955/74 Heading F2F A differential piston 28, having its larger face exposed to pressure for brakes and its smaller face exposed to source pressure, has a valve member 40 engageable with a stop 42 of the piston to close communication between faces of the piston, but held from the stop by an abutment 54 when the piston is in an unactuated position determined by a resilient return device 60, the abutment being movable under the opposing action of the source and brake pressures so that upon disengagement of the abutment with the valve member, the latter interrupts communication. Upon pressure build up from a source 18 (a tandem master cylinder) the piston 28 is retained in its unactuated position with the valve open until the pressure on the larger face moves the piston rightwardly to close the valve. Subsequently, pressure buildup depends on the differential face areas of the piston such that brake pressure (for rear brakes) rises less than source pressure. However, at a given pressure level (for emergency braking) the pressure differential acting on a piston 52 with the abutment overcomes a spring 56 to move the abutment rightwardly to again open the valve for equal brake pressure increase to source pressure increase. A lever 62 between the spring 60 and the piston 28 varies the piston characteristics to accommodate loading on the vehicle rear axle.

Title: Improvements in or relating to telecommunications exchange systems
IPC: H04Q3/00
Filed: 1969-08-29
Abstract: 1,255,514. Automatic exchange systems. SIEMENS A.G. 29 Aug., 1969 [30 Aug., 1968], No. 43034/69. Heading H4K. In an exchange system in which a subscriber's number does not identify the exchange to which he is attached, calls being set up by passing a wanted number as hunting data from an originating exchange to all adjacent exchanges and from these onwards until the wanted number is recognized, the hunting data is sent over free inter-exchange channels nominated for such signalling, each exchange receiving hunting data keeping a record of the channel over which the data was received, and/or is to be sent, so that such channels may be seized for a connection when a free terminal identity has been ascertained. The connection may be established backwards from the exchange found to be serving the wanted subscriber, the channels identified as those nominated for sending the associated hunting data, should they still be free, being seized exchange-by-exchange until the originating exchange is reached. Since this process may result in parallel inter-exchange paths being set up over alternative routes, the originating exchange sends a message in all outgoing directions to cancel unwanted routes. Alternatively the wanted subscriber's exchange may revert an availability signal which causes the originating exchange to steer a connection over the catalogue of hunting data channels while discarding alternate routes. The reversion of an availability signal may effect seizure of hunting data channels in that it precipitates nomination of new hunting data channels before the connection is set up from the originating exchange. If the wanted subscriber is busy a message may be reverted to clear hunting data records at intermediate exchanges while at the same time carrying the busy signal to the originating exchange. Alternatively, if no connection matures within a fixed time the originating exchange sends an instruction to clear records pertinent to the call. In working between some exchanges of the system the identity of an incoming group of channels may be recorded in place of the channel specifically nominated for receipt of hunting data, a connection being set up in response to hunting data by seizure of one of the group of channels rather than the specifically nominated one. When a channel nominated for hunting data transmission is seized for a connection, a new channel is nominated for such data transmission and the identity of the new channel is substituted for that of the old channel in respect of connections for which hunting data has already been received over the old channel. The inter-exchange channels may be individual inter-exchange circuits, frequency division multiplex channels, or time division multiplex channels, and the data may be transmitted as multi-frequency signals or as pulse amplitude or pulse code modulations.

Title: Temperature control system

Filed: 1961-12-05
Abstract: 939,052. Automatic temperature control systems. REGULATOR A.G. Dec. 5, 1961 [Dec. 6, 1960], No. 43408/61. Class 38 (4). An automatic control system for an air conditioning plant using thermistors as temperature sensitive elements to give say a rising room temperature on each side of a datum, comprises a resistor bridge circuit R1, R2, R5, R6, having resistor diagonals R3, P1, P2 and a thermistor R4 sensitive to outside temperature. Due to the diodes D1, D2, whether the thermistor resistance is above or below the datum value, the circuit output will be positive in relation to earth. The circuit is in series with a bridge network comprising resistors r 1 -r 3  and thermistor TH sensitive to inside temperature, hence the lower bridge modifies the output of the upper bridge. By adjustment of the two circuits, the output characteristic of the system may rise or fall on each side of the datum, say 20 C. and may even be flat around the datum point. Other arrangements providing particular temperature characteristics are described in the Specification. The thermistor R4 may be replaced by a light sensitive or humidity sensitive device.

Filed: 1973-09-17
Abstract: 1396068 Semi-conductor device SIEMENS AG 17 Sept 1973 [19 Sept 1972 8 Jan 1973] 43510/73 Heading H1K A highly doped surface zone formed in a window on a semi-conductor body, is covered with an insulating layer to protect it from oxidation and the dopant is diffused further into the body by heating in an oxidizing atmosphere. The highly doped surface zone is formed by coating an exposed semi-conductor surface with a dopant from the gas phase. In an embodiment an SiO 2  layer 25 having a window 26 therein is formed on an epitaxial N-type layer 22 of Si. The epitaxial layer 22 is formed over a P-type Si substrate (21) having a highly doped N-type buried zone (23) and is surrounded by a P-type isolating frame (24, -Fig. 4, not shown). A highly doped surface zone 30 is formed by exposure to B 2 H 6 , the boron glass so formed is heated in moist nitrogen and removed by etching. A strip 31 of silicon nitride is formed and the zone 30 driven in by heating in an oxidizing atmosphere to form the base zone 32 of a transistor. Since the surface of the highly doped zone is converted to SiO 2  some of the boron atoms are lost thereby and the layer resistance of zone 30 is less under the nitride strip 31 than elsewhere. Furthermore the zone 30 is not driven in as far immediately under the strip (Fig. 6, not shown). An emitter zone 33 is formed by diffusion of phosphorus and the zone 32 simultaneously driven in further to give a flat PN junction 34. If arsenic is used to form the emitter zone then the base zone is not driven in as far and the PN junction 41 is formed.
