Patent GB-635335-A (GB)
Abstract: 635,335. Treating gases by electric discharges. TRIGGS, W. W. (Patelhold Patentverwertungs & Elektro-Holding Akt.-Ges.). Sept. 8, 1944, No. 17191. [Class 39 (i)] In a method of treating flowing gases or vapours by means of an arc discharge, two electrodes are arranged symmetrically with respect to an axis and a source of very high-frequency current is connected thereto so that a high-frequency arc discharge is produced which at least partly-fills the space between the electrodes and the flow of gases is led symmetrically to the axis of the electrode system in the region of the arc discharge. In the arrangement shown, one electrode D forms a nozzle through which the gas flows and the second electrode M is arranged above. Alternatively, a rod electrode may be arranged in the aperture of a nozzle co-operating with a ring or cylinder electrode above. The surface of the latter may be sufficiently great for the current in the neighbourhood thereof to be purely capacitatively conveyed so that no discharge appears in this region. In another construction two parallel rod-like electrodes are used subdivided longitudinally to produce reactances in series with the arc to stabilize it. The container may be constructed as a cavity resonator.

Title: Preventing cavitation in hydropneumatic shock absorbers
IPC: F16F9/40
Filed: 1978-07-25
Abstract: In a hydropneumatic shock absorber comprising an oil-filled inner cylinder 4, an outer cylinder 13 and a gas-containing reservoir defined between the two cylinders, a throttle orifice 5 in the inner cylinder creates, on the contraction stroke, a back pressure in the working chamber 4B which ensures that the piston valve 10 opens to prevent cavitation in the working chamber 4A. This reduces the pressure necessary for the gas space. A one-way valve integral with the piston rod seal allows fluid to flow from the inner cylinder to the top of the reservoir on the expansion stroke. <IMAGE>

Patent GB-2058604-A (GB)
Title: Purification system for use in blood treatment
IPC: A61M1/34
Filed: 1979-09-21
Abstract: In a purification system for blood treatment the dialysate or ultrafiltrate 1 from the blood treatment system is purified and returned 10 to the treatment system to the patient during treatment. Reverse osmosis is a suitable purification method. Because a reverse osmosis purification system 7, 8 has a very pure output 10 there is no need for the pathway 1, 2, 3, 5, 6 from the treatment system to the purification system 7, 8 to be kept sterile, and the initial charge 4 to this pathway may be tap-water. The rejected fraction from the reverse osmosis is recycled 9. Because the dialysate or ultrafiltrate is recycled the volume of waste liquid built up during treatment is much reduced, thereby alleviating the disposal problem. The waste materials will accumulate in a reservoir 3 in the non-sterile part of the fluid circuit. The system can be compact and easy to use, and can be powered by normal mains electricity. <IMAGE>

Title: Control of DC series motors
IPC: H02P7/298
Filed: 1979-10-12
Abstract: A controller for a DC series motor comprises a main drive thyristor SCR, for controlling armature voltage and a field diversion path R9, T2 for weakening the field, when thyristor bypass S1 is closed, to provide a diverted speed range in excess of the speed range achievable through thyristor control. The degree of field diversion is automatically varied by an armature current sensor to maintain the optimum degree of field diversion despite variations in torque requirement and to maintain armature current approximately constant during the diverted speed range. The armature current is sensed by a magnetoresistive device Hz, compensated for temperature and used to control the frequency of an oscillator whose output controls switch T2 in the diversion path. Amplifier A2 ensures no field weakening for high field voltages. Switch T2 may be a transistor or thyristor. <IMAGE>
