Title: Telephone circuit
Inventor: BURGIN KENNITH NEVILLE
IPC: H04M1/58
Filed: 1982-08-25
Abstract: A telephone speech circuit includes a microphone amplifier and an earpiece amplifier within an integrated circuit (5) and a common transistor (T1) through which received and transmitted signals pass to or from the subscriber's line and a sidetone cancellation circuit.   The sidetone cancellation circuit includes a summing circuit arranged between pin 6 of the integrated circuit and the input of the earpiece amplifier (Figure 2) and an inverting amplifier (T2, Ze) connected to pin 9 of the integrated circuit (5). The inverting amplifier (T2, Ze) amplifies the output of the microphone amplifier which it receives via pin 9 of the integrated circuit 5 for application to the subscriber's line. The output of the inverting amplifier is also fed via transistor (T1), resistor (R2) and capacitor (C2) to pin 6 of the integrated circuit (5). Within the integrated circuit (5) (Figure 2) the pin 6 is connected to a first input of the summing circuit while the output of the microphone amplifier is coupled to a second input of the summing circuit. Thus the output of the summing circuit is an attenuated version of the signal at the output of the inverting amplifier and sidetone is at least partially cancelled. <IMAGE>

Title: Logic circuit array
Inventor: BREWER ROBERT JOHN
IPC: H03K19/096
Filed: 1982-11-10
Abstract: By using de Morgan's theorem, Boolean algebra equations can be converted so that it is possible to design a compact logic array of the type in which a node is charged during one clock phase & conditionally discharged in another clock phase, depending on the input signals applied to it, in which the capacitative nodes (44, 46) within the array may be precharged directly (via 10A) rather than through the logic FETs. This is done by arranging transistors as series connected blocks of parallel- connected FETs (Fig. 2) instead of the prior art parallel-connected blocks of series-connected FETs (fig. 1). & using the complements of the input signals used in the prior art of fig. 1. In consequence a logic array can be fabricated to implement the converted equations, which array can be operated at higher speeds than known circuits for substantially the same power consumption or, conversely, at the same speed as the known circuits with a substantially lower power consumption. <IMAGE>

Title: Elastomer based adhesive compositions
Inventor: TOY LESTER TUNGNAN
IPC: B29C63/20
Filed: 1982-12-23
Abstract: A substantially solvent-free adhesive composition consists essentially of an elastomer and tackifier, a metal oxide and, optionally, a plasticizer. The elastomer is selected from the group consisting of polar elastomers and unsaturated elastomers which have at least 5 mole percent unsaturation said elastomer being a non-crystalline elastomer or an elastomer which has a slow rate of crystallization such that after a time period of at least 100 hours has elapsed following subjecting the elastomer to a temparature of 70 DEG C for 30 minutes, the elastomer has a room temperature Shore A hardness of less than 60. The adhesive compositions can be formed into a shaped article, such as of a tape, film, sheet or tubular sleeve, if desired. The compositions have high adhesive strength for bonding together a variety of substrates. The adhesive is particularly useful with a dimensionally recoverable article, such as a shrinkable sleeve, to bond the recovered sleeve to a substrate such as an electric cable.

Title: Piston/cylinder seal construction
Inventor: ORGAN ALAN HENRY
IPC: F15B15/14
Filed: 1983-05-04
Abstract: A fluid-pressure-operable device 1 includes two relatively-movable components 2, 3 defining a variable-volume working chamber 9. A sealing element 5 of elastomeric material is carried, or formed, by one of the components and is in sliding and sealing engagement with the other of the components normally to resist escape of fluid under pressure from chamber 9 to the exterior thereof. That face 15 of element 5 remote from the chamber is so provided with channel 16 that as pressure in the chamber increases the element is permitted progressively to deform and some of the material of the element thus displaced is then accommodated by the channel. When the pressure exceeds a predetermined value, deformation of the element is such that sealing engagement of the element with the other of said components is broken so that the pressure in chamber 9 is relieved to the exterior thereof.

Title: Improved equity access system
Inventor: JOHNSTON MICHAEL A
IPC: G06Q40/00
Filed: 1983-12-14
Abstract: Data processing for an improved equity access and management account flexibly permits owner access to a line of credit. The line of credit may typically be secured, as by the equity in a client's home or other asset. Charges against the client account may be of varying forms, e.g., by cheque, charge card or cash advance, and decrement available credit remaining in the credit line when authorized. Account loan principle is increased when charges are incurred, and reduced upon full or partial payment. Charges for interest, late fees and the like, sometimes differing in rate or amount based upon an independent variable such as security situs, are assessed against client accounts, and account status and balances are periodically reported.

Title: Compaction of spent nuclear fuel cans
Inventor: SULLIVAN HARRY
IPC: B30B9/32
Filed: 1984-01-31
Abstract: Hydraulic press apparatus (10) for compacting waste material eg. spent nuclear fuel cans (11) comprises a fixed frame (12), a movable cross head (13), a press crown (17) and three groups of piston/cylinder devices (22, 25; 23, 26; 21, 24) having their pistons (31 to 36) connected to the cross head (13) and their cylinders (21 to 26) secured to the press crown (17). A control means connects the first group of devices (22, 25) to hydraulic fluid in a reservoir which is pressurised initially by gas from gas accumulators to move the cross head (13) and a quill (14) secured thereto towards the frame base (12) to compact the waste (11) at a first high rate under a first high loading. Compaction then proceeds at a lower second rate at a lower second loading as the hydraulic fluid in the reservoir is pressurised by a pump. At two subsequent stages of compaction of the waste (11) at which resistance increases causing a pressure rise in cylinders (22, 25) the control means causes hydraulic fluid to be passed to the second group of devices (23, 26) and thence to the third group of devices (21, 24), the compaction rate reducing at each stage but the compaction force increasing. <IMAGE>

Title: Measuring range and/or radial velocity of a moving target
Inventor: STOVE ANDREW GERALD
IPC: G01S13/58
Filed: 1985-03-13
Abstract: A continuous-wave FM radar system comprises a voltage-controlled RF oscillator (1) the output frequency of which is swept repeatedly in both senses by means of a voltage waveform generator (19), whose waveform cycle comprises two upward sweeps followed by two downward sweeps. The oscillator output signal is fed to an aerial (3) and a portion of the transmitted signal is mixed with the return signal in a mixer (7). The ranges and/or velocities of reflecting moving targets are determined by means of a computer (100) which is fed with the output of a spectrum analyser (15) for the resulting beat-frequency signals, range-velocity ambiguities due to Doppler shifts being resolved by determining each range and/or velocity from a pair of spectral frequencies which arise from sweeps of the oscillator frequency in one sense and in the other sense respectively. In order to make the task of the computer easier in deciding which frequencies constitute related pairs a signal storage and differencing circuit (11) subtracts the mixer output signals which arise from successive sweeps of the oscillator frequency in the same sense one from the other and feeds only the result to the spectrum analyser, thereby ensuring that the spectral frequencies outputted by the spectrum analyser correspond only to moving targets.   <IMAGE>
