Patent GB-2174269-A (GB)
Title: Private automatic branch telecommunication exchange
Inventor: REES FREDERICK HENRY
IPC: H04M7/12
Filed: 1985-04-20
Abstract: When the public telephone network is enhanced by the replacement of an analogue exchange by an ISDN exchange, it is desirable for PABXs connected thereto to be afforded ISDN features. This is preferable to replacing the existing non-ISDN PABX, especially where it is relatively modern, which PABX may itself be analogue or digital in nature. To achieve this, the PABX is provided with a digital overlay (2) which provides ISDN type features for some at least of the PABX lines. There is also a so-called mixing multiplexer (1) which acts as an interface between the public network and the PABX. This multiplexer (1), which is microprocessor controlled, has one port (K), which is a multi-line IDA (Integrated Digital Access) giving access to the digital overlay (2), and hence to the lines (5) served thereby. The multiplexer (1) also has a port (L) which gives multi-line access to the existing PABX switching network (3). This port (L) provides such format conversion, or analogue/digital conversion, as is needed, dependent on the nature of the switching network (3). This provides a number of useful facilities in a simple and economical manner, using modular techniques. <IMAGE>

Title: Beacon tracking system
Inventor: WATSON BARRY KENNETH
IPC: H01P1/213
Filed: 1985-08-29
Abstract: A beacon tracking system for an antenna 1 comprises a mode coupler 2 having a central waveguide 3 located in the antenna feed chain, and at least two pairs of diametrically opposite rectangular auxiliary waveguides 7, 8 coupled to the central waveguide 3. Each of the auxiliary waveguides 7, 8 is designed to extract, at the beacon frequency, a fundamental mode and a higher order mode resulting from off-axis signals, which combine to produce a resultant radiation pattern lobe representative of antenna boresight deviation, in the azimuth and elevation planes, in respective pairs. An electronic switching device 12 operates to connect the outputs from the auxiliary waveguides 7, 8 in a predetermined repetitive sequence to a tracking receiver 13 which analyses the outputs in turn to provide antenna pointing error correction signals  DELTA x and  DELTA y by effectively comparing the amplitude of the radiation pattern lobe in each auxiliary waveguide 7, 8 with the boresight amplitude. <IMAGE>

Title: Valves
Inventor: TAYLOR ERIC
IPC: F16K27/06
Filed: 1985-09-12
Abstract: A service isolation valve for use in the gas supply industry comprises a body constituted by a tubular plastics casing 10, e.g. of polyethylene, with an internal tubular metallic insert 12, e.g. of stainless steel or brass keyed to the casing 10 to resist relative axial movement therebetween. The casing 10 and the insert 12 define a fluid flow passage in which is disposed a pair of spaced elastomeric valve seats 17, 19 and a rotatable ball valve member 18. Means is provided to prevent leakage of fluid between the casing 10 and the insert 12 upstream and downstream of the valve seats. As shown, the insert 12 has keying grooves A, C and a groove B that receives an O-ring seal 15. In a modification (Fig. 4), the insert (52) has keying serrations (57) and fluid leakage is prevented by a steel sleeve (58) pressed into the casing (55) after moulding to cause the plastics to flow into an internal annular groove (4) in the insert (52). <IMAGE>

Title: Separable slide fastener
Inventor: TSUBOKAWA YOSHITOKI
IPC: A44B19/34
Filed: 1985-10-16
Abstract: A separable slide fastener includes a pair of stringer tapes (11, 12) made of a pliable thread-free material such as a nonwoven fabric or a plastic material, a pair of rows of coupling elements (13, 14) on the respective stringer tapes, a separable end assembly (19) connected to bottom end portions of the stringer tapes, and reinforcement strips (23, 23) extending along the inner longitudinal edge of at least one stringer tape a the bottom end portions. The reinforcement strips (23, 23) have a length greater than that of the bottom end assembly (19), with the result that portions of the stringer tape contiguous to the upper end of the end assembly are prevented from being bent or stretched even after repeated operation of the fastener. The reinforcement can cover the whole length of the tape. <IMAGE>

Title: Machinery-protection clutch assembly
Inventor: SARKILAHTI OSMO
IPC: F16D25/12
Filed: 1987-02-23
Abstract: Clutch equipment between the driven shaft (14) and the driving engine (1) of a ship, for example, for the protection of the drive machinery on occasional variations in the loading of the driven shaft (14) supporting a propeller (16), comprises two clutches (7, 11). The connection between the driving shaft (2) and the driven shaft (14) is produced by means of the multi-plate friction clutch (7) during normal loading. When the load increases, a change in the ratio of the speeds of rotation of the primary shaft (2) and the secondary shaft (14) of the clutch (7) beyond a certain value gives an impulse for uncoupling of the clutch (7), whereby the torque transmitted by the hydrodynamic clutch (11) is used as an indication of the loading situation of the propeller. When the obstacle which increased the load is removed and when the ratio of the speeds of rotation of the shaft (2, 14) is again changed, this change gives the impulse to engage the clutch (7) again. (Fig. 2) depicts a modification in which the clutch plates and the blade wheels of the hydrodynamic clutch are located within a common housing. The clutch (11) may be displaced by some other member rotating in a medium or a magnetic field. <IMAGE>

Title: Aircrart co-ordinated flying controls
Inventor: NORMAN NIGEL DESMOND
IPC: B64C13/28
Filed: 1987-07-15
Abstract: An aircraft has an aileron tab 7' and a rudder tab 8' which are connected to the rudder pedals 13 and control column (9) (Fig. 1) respectively. The arrangement is such that, on operation of the appropriate control to cause the aircraft to yaw or bank respectively, the aircraft is also caused to bank or yaw respectively by movement of the ailerons 7 or rudder 8 respectively, in a direction opposite movement of the respective aileron or rudder tab, in the assisting direction. This enhances the overall turning characteristics to reduce the effort that must be applied by a pilot. A degree of lost motion may be provided in the aileron tab control linkage. <IMAGE>
Patent GB-2194664-A (GB)
Title: Speaker drive system
Inventor: AMLANI MANHER
IPC: H04R3/08
Filed: 1987-08-20
Abstract: A speaker drive system has a sweep circuit (2) connected via a resistor network (3) to a multivibrator (4). Both sweep circuit (2) and multivibrator (4) are powered from a power supply (5), and multivibrator (4) generates a square wave which is fed to the inputs (6),(7) of the speaker. A zener diode (1), whose breakdown voltage is lower than the maximum voltage of the square wave applied to the speaker, is connected between the output of the multivibrator (4) and one of the speaker inputs (6),(7). The zener diode is chosen so that it will pass freely the square wave to the speaker but will not pass transitory oscillations occurring due to the presence of a resonant frequency due to interaction between capacitance C6 and the inductance of the speaker. <IMAGE>

Title: Steam enhanced oil recovery method
Inventor: WALL ROBERT G
IPC: C09K8/94
Filed: 1988-05-25
Abstract: A method of enhancing oil recovery from a reservoir in a petroleum-bearing formation using foam to improve the effectiveness of steam or gas to mobilize viscous crude, either for steam stimulation in a single well or for steam drive between wells, employs a foamable anionic surfactant which is a multi-branched alkyl aromatic sulfonate having an average molecular weight in the range from 400 to 600 and at least one alkyl group having a carbon content of from 15 to 30 carbon atoms which is branched with at least three carbon atoms being secondary or tertiary carbon atoms. It has been found that such multi-branched alkyl aromatic sulfonates have the ability to foam in the presence of substantial pore volumes of residual oil and thereby mobilize significant amounts of producible oil by diverting steam to less-permeable zones.
