Title: Air-bath system
Inventor: CHARLES COLIN
IPC: A61H33/00
Filed: 1987-12-10
Abstract: A tub 1 of an air bath system comprises side walls 2 and a base 3 apertured to receive a plurality of nozzle assemblies 4. Air line 5 connects each nozzle via a manifold 6 to a blower unit 9. Each nozzle is of conical configuration, the arrangement being such that water entering the nozzles after main drainage from tub 1 is complete and air supply via line 6 is ceased is ejected by instantaneous actuation of unit 9. Resulting ejected water backflow and entrained soil runs off the conical surface of each nozzle 4 without substantially re-entering the nozzles 4 to cause blocking. <IMAGE>

Title: Pivoting vacuum fixture for testing P.C.B.
Inventor: RICKETTS ANDREW CHARLES
IPC: G01R1/073
Filed: 1988-02-27
Abstract: A P.C.B. (10) is supported on a receptor (12) which carries a flexible sealing strip (14) which is adapted to receive and locate the board such that the board is supported around its periphery. A conduit 22 emanating from a vacuum pump (not shown) is connected to an orifice 23 of a chamber 24. Chamber 24 leads to a duct 25 made up of a short cylindrical portion 26 which enters chamber 24 and a further portion 27 which leads to an orifice 28 in carrier member. The vacuum pump is thereby connected to the chamber which may thus be evacuated. The chamber may be raised by lifting the forward edge 29 of the receptor. Hinging is by virtue of rotation about cylindrical portion 26 of chamber 24 and a corresponding opposing simple pivoting hinge. Pivoting about cylindrical portion 26 results in chamber 24 being substantially at right angles to duct portion 27. Passage from orifice 23 to chamber 16 is preserved, so that the chamber may be evacuated both during hinging and when the chamber is in its hinged position. <IMAGE>

Title: High frequency voltage/current-measuring circuit
IPC: G01R19/03
Filed: 1990-02-22
Abstract: A circuit (Fig 3) for measuring the R.M.S. voltage of a high frequency signal (VAC (e.g. 2MHz) comprises two series- connected ntc thermistors (TH1, TH2) in a bridge circuit which is energised by a constant current source (1). The unknown signal is applied (T1, T2) across one (TH1) of the thermistors and the resulting change in the resistance causes a D.C. output voltage to appear across the balanced terminals (T3, T4) of the bridge. This output voltage is proportional to the square of the R.M.S. voltage of the A.C. signal VAC. In another embodiment, (Fig 4) two ptc thermistors are connected in parallel in a bridge circuit which is energised by a regulated voyage source (2), and are used to measure R.M.S. current IAC. In each case, the thermistors are preferably operated in a negative slope resistance portion of their voltage-current characteristic. <IMAGE>

Patent GB-2242806-A (GB)
Title: Handover techniques for cellular radio
Inventor: RAMSDALE PETER ALAN
IPC: H04W36/04
Filed: 1990-04-06
Abstract: In a cellular radio system having a two layer cell structure comprised by macrocells (1) overlaying microcells (2), handover occurs only via the macrocell layer. Thus when the quality of a call handled by a microcell (2) deteriorates below predefined criteria the call is handed up rapidly to the umbrella macrocell and is only handed back down to a microcell when a handset has been in that microcell for a predetermined time and the quality of the link thereto exceeds predefined criteria. A handset moving quickly through a microcell thereby avoids unnecessary handovers from macrocell to microcell and back again. <IMAGE>

Title: A method of and apparatus for making endless ribbons
Inventor: CHOW YIU WAH
IPC: B26F1/38
Filed: 1990-06-28
Abstract: It is known to make endless nylon ribbons for use, e.g. in computer printers by joining the two ends of a length of ribbon by means of ultrasonic welding. However, the quality of print in the vicinity of such joints deteriorates with use. In the method of the invention, an endless, seamless ribbon is prepared by cutting from a sheet of ribbon material having a thickness equal to the desired thickness of the ribbon a number of endless, seamless ribbons. The ribbons may be produced by rotating a turntable supporting a circular sheet below radially equi-shaped heated knives 3. Ribbons thereby produced have the advantage of seamless ribbons in terms of print quality, but are comparatively cheap to manufacture. <IMAGE>

Title: Circuit arrangement for monitoring the control circuitry of a plurality of valves
Inventor: BLECKMANN HANS-WILHELM
IPC: B60T8/32
Filed: 1990-07-13
Abstract: A circuit arrangement for monitoring the control circuitry of valves comprising the power transistors LT1 - LT4 and their circuitry, in particular for detecting defects as well as for leakage currents or by-path currents, consists of a comparator circuit 1, an OR circuit 2 and a further comparator element XOR4. Via the monitoring circuit, actuation connections S1 - S4 of electromagnetically-operable valves are connected to one single output A3. By applying short test pulses to the actuation inputs E1 - E4 of the control circuitry or final stages LT1 - LT4 and by comparing the signal variation at the output A3 with the test pulse variation it is possible to detect defects, leakage currents and the like. Evaluation of the output A3 is obtained by means of a computer. The values may be braking pressure control valves of an antilock control system or of a traction slip control system. <IMAGE>
