Patent GB-2076238-A (GB)
Title: Radio receiver
IPC: H04B1/26
Filed: 1980-09-02
Abstract: This invention relates to a radio receiver for receiving frequency shift keyed radio signals. The receiver has a mixer 2 which receives the transmitted signals, a local oscillator 3 which feeds a mixing signal to the mixer 2 and a detector 7 which is fed from the mixer 2 through a single receiving channel. A chopper 8 applies a chopping signal to the local oscillator 3 to change the frequency of the oscillator between two values none of which lies midway between the two frequencies, the chopping signal being fed also to the detector 7 in synchronism with that applied to the local oscillator 3 to logically compare the chopper signal with the mixer output so that the detector detects the transmitted binary bits. The invention is useful in the fields of paging, telemetry and communication systems. <IMAGE>

Title: Medical treatment and apparatus therefor
Inventor: WATSON JAMES VICTOR
IPC: A61M39/02
Filed: 1983-04-06
Abstract: A subcutaneously implantable diffusion chamber is proposed, the chamber housing hybrid living cells adapted to produce sub-cellular material capable of affording beneficial activity in the body for medical purposes and the chamber having a wall defined by a membrane which, in vivo, inhibits the free diffusion therethrough of the cells but not sub-cellular material. The cells can be of hybridoma form to produce monoclonal antibodies specific for tumours. The membrane acts to allow outward diffusion of the antibodies or other active sub-cellular material, to allow inward diffusion from the host body of oxygen, nutrients or other sub-cellular material to sustain the cell effectiveness, and to inhibit outward diffusion of the cells and prevents metastasis as a neoplastic growth or other undesirable results. The membrane preferably only passes material of up to about 0.2 mu m diameter. <IMAGE>

Title: Logging while drilling system
Inventor: BERKENKAMP GARY DEAN
IPC: E21B47/18
Filed: 1983-05-18
Abstract: A method for recovering data from a data signal originating from a downhole apparatus and transmitted to the earth's surface through drilling mud comprises measuring pressure pulsations in a mud flow line at the earth's surface in two spaced apart locations (30, 32). One of the measured pressure pulsation signals is time shifted an amount equal to the travel time of the group propagation acoustic velocity in the mud between the two pressure sensors (30, 32), and one of the two signals has its polarity reversed. The two signals are then combined to cancel any downward propagating energy from the combined pressure data signal. The combined pressure data signal is then processed by each of n matched filters (46, 48) in a baseband PCM system to determine the presence or absence of one of n symbols in the residual data signal. Each output of the filtered data signals is then input to a detector (50) to identify either the presence of a symbol or absence of the data signal. <IMAGE>

Filed: 1983-08-20
Abstract: An oil drilling tool having a plurality of stabiliser blades 13 and with each blade housing an undercut groove containing an inlay 14 of a wear resistant material, is characterised in that each groove runs substantially transverse to its blade. This makes it possible to cut the grooves by a simple tool such as a lathe. The grooves could be formed by removing material in a series of adjacent but axially spaced circular cuts. Alternatively they could be part of a continuous left-hand or right-hand helix. Preferably a single respective backing strip 15 extends the length of each blade and all the wear resistant strips of that blade abut it. <IMAGE>

Title: Telephone exchange conferencing
Inventor: HANSEN BJORN NAPIER
IPC: H04M3/56
Filed: 1984-08-01
Abstract: In our earlier Application No. 8305572 (B.N. Hansen 2) and No. 8307143 (B.N. Hansen 1), a handsfree system is described in which the incoming and outgoing speech channels of a handsfree set are monitored. The result of these monitorings assesses which channel has the higher amplitude, and the lower amplitude channel is attenuated, thus avoiding howling. There is also a noise threshold adjustment used in this monitoring. The above technique is, in the present system, extended to its application to conference calls using handsfree sets. Here the speech amplitudes for all conferees are sampled and the largest is routed to all other conferees, who are attentuated. This technique is also extended to its use where a conference call involves an analogue junction to a remote exchange. As in the single handsfree case, this operation also takes into account the lines' noise condition. <IMAGE>
