Patent GB-1212989-A (GB)
Title: Pressure control apparatus
IPC: G05D16/10
Filed: 1967-12-22
Abstract: 1,212,989. Pressure control systems. INTERNATIONAL BASIC ECONOMY CORP. Dec.22, 1967 [Dec.29, 1966], No.58371/67. Heading G3P. A pilot-operated unloading valve for a pump can respond directly to high rates of change of pump delivery pressure above the level at which the pilot valve is actuated. As shown, the pump delivers into line 213-A and, when the pressure reaches a predetermined level, pilot spool 210 is depressed to allow flow to drain via restriction G2 and lines 214, 211-A. This flow produces a pressure drop across restriction G2 and the downstream pressure acts via restriction G3 in chamber 272 below spool 222. The chamber 220 above spool 222 senses pump delivery pressure through restriction G5 and a restriction G6 in parallel with check valve 219. Thus, during relatively slow variations in pump pressure, spool 222 is subjected to the pressure difference across restriction G2 and moves downwardly to connect line 216 to drain to limit the pump pressure. However, during rapid pressure fluctuations, restriction G3 is effective to allow spool 222 to respond to the fluctuations as communicated to chamber 220. A capacitive oil-filled chamber 270 or a cylinder with a spring-biased piston communicates directly with chamber 272. When the pilot spool is in its upper position, it connects line 213A to chamber 272 via line 207 so that pump pressure acts on both ends of spool 222. In the modification of Fig.16, not shown, spool 222 controls the flow to and from a pump unloading mechanism. In Fig.17, not shown, the pilot spool only controls the flow to drain. A separate pressure responsive (300) controls the flow to a line 207-B corresponding to line 207 above.

Title: Kinescope manufacture involving electroless deposition techni ques
IPC: H01J9/14
Filed: 1970-12-30
Abstract: 1332000 Making aperture masks for cathode ray tubes RCA CORPORATION 30 Dec 1970 [30 Dec 1969] 61848/70 Heading B3A A method of making an apertured colour selection mask for a colour television tube includes the steps of providing on one face of a thin sheet of metal a perforated pattern of catalytic electroless deposition initiating material, forming in said shut permanent apertures one end of each of which is partially closed by said catalytic material and electrolessly or electrolessly and electrolytically depositing on the catalytic material further material which is opaque or is subsequently rendered opaque to form temporary apertures smaller than said permanent apertures whereby said mask is adapted to be used in the printing of phosphor deposits on the tube screen. A metal substrate 42 with a catalytic layer 46, of e.g. palladium, copper, nickel, cobalt or chromium, has a perforated pattern 48 of etch resistant material applied to the layer 46, which step may (not shown) remove the catalytic layer at the apertures 50 of the pattern 48. A second perforated pattern 52 with apertures 54 aligned with the apertures 50 of pattern 48 is optionally applied to the other face of the substrate. Portions of the substrate, and of layer 46 if not already removed, aligned with the apertures 50, 54 and portions of the substrate only adjacent the apertures are then removed by etching to leave areas 58 of catalytic layer extending partly across openings 56 etched in the substrate. Material, preferably metallic and preferably a nickel-boron alloy, is electrolessly deposited at 62 on the exposed face of the areas 58. Other suitable metals are nickel-phosphorous alloys, copper, cobalt and nickel and alloys of these metals. The material may be rendered opaque after deposit. The etch resist pattern and the catalytic layer are preferably removed before the mask is used as a photographic master in printing phosphor deposits on a transparent substrate to form an image screen for a television tube. If such removal takes place, the electrolessly deposited layer 62, may be built up by further electroless deposition (62a), Fig. 6 (not shown) or by electroplating, Fig. 7 (not shown) which latter causes plating also of the walls of the apertures 56. After the screen-printing the opaque deposits are removed by electro-chemical stripping or chemical etching. The mask (30) and screen (8) are subsequently mounted in a colour television tube (10) Fig. 1 (not shown).

Patent GB-2022345-A (GB)
Title: Control circuits for stepper motors
IPC: H02P8/12
Filed: 1979-05-25
Abstract: A stepper motor has two pairs of windings AA and BB (not shown), each phase winding being energised when a respective signal A,A,B,B is supplied by logic 11, a typical operational sequence for phase A being as follows:- signal A switches on transistor VT1; when the winding current sensed by resistor R2 reaches a reference value of comparator 13, the latter switches off VT1; after a predetermined time set by monostable 14 comparator 13 switches VT1 on again and the cycle repeats for the duration of signal A. During the OFF periods of VT1 transformer action between the A and A windings 12, 15 produces reverse current through winding 15 and diode D3 to supplement the torque produced by winding 12, without requiring further current from the supply. When changing from signal A to A, members 16-19 switch off transistor VT3 to dissipate in resistor R1 the energy in the circuit 15, D3. When comparator 13 is subsequently operated to switch off transistor VT2, members 18, 19 switch VT3 on again. The speed/torque characteristic is controlled by the signal from member 18 occurring during the OFF period of VT3, which signal controls the time constant of a circuit 20 to progressively vary the reference voltage applied to comparator 13, for example to provide a high current at high stepping rates and a reduced current at low rates by progressive decrease of the reference voltage. <IMAGE>

Title: Steering valve arrangement for vehicles
IPC: B62D5/083
Filed: 1979-09-05
Abstract: A steering valve arrangement for a hydraulically operated steering system of a vehicle has two spring-loaded, seated inlet valves 10a and 10b. In such arrangement the supply from a pressure medium source 2 to a respective working chamber 12a; 12b of an adjusting motor 14 is closed in the neutral position of the steering system. The springs 25a, 25b of the seated valves 10a, 10b counteract the force which is generated by the drop of pressure respectively occurring at the seated valves. The arrangement includes two rotary members 22, 23 arranged coaxially one within the other and rotatable in relation to one another upon a steering movement being effected. Upon such steering movement being effected in one direction or the other, the rotary members 22, 23 reduce the force of the valve spring of the seated valve. A centring spring, in the form of a torsion rod 27 is operative between the rotary members 22, 23. In order to obtain a comparatively flat rise in the steering force-pressure characteristic on both sides of the neutral position, there is so connected to the valve spring and in opposition to it, a further spring (fine control spring) that upon a steering movement the rotary members first act on both springs and act directly on the valve spring when the travel of the fine control spring has been used up. The rotary members 22, 23 are constructed as components of a rotary slide valve which forms adjusting throttles 16a, 16b for the working fluid flowing back out of the adjusting motor 14. <IMAGE>
