Abstract: 1351966 Hydraulic buffers NISSAN MOTOR CO Ltd and ATSUGI MOTOR PARTS CO Ltd 21 Oct 1971 [26 Dec 1970] 48927/71 Heading F2S An hydraulic piston-cylinder buffer for a vehicle has a permanently open restricted passage 12a through the piston 12 and a valve 20-22 to relieve pressure in the chamber 13 below the piston, and the cylinder is filled with silicon oil, whose compressibility provides a spring force to return the piston after impact. The preferred oil is methyl-silicon. The pressure relief valve comprises a resilient valve plate 21 which flexes away from the piston 12 to open the passage(s) 20 in response to a certain pressure in the chamber 13 against the bias of Belleville springs 22 which seat on a stop member 19 secured to the piston rod 15 and limiting its outward movement. In Fig. 3 (not shown) the liquid chamber 13 is divided into two parts (13a, 13b) by a fixed partition (26) which has a through passage (26a) of smaller cross-section than the piston passage 12a, and the part (13b) farther from the piston 12 is acted on by gas (e.g. nitrogen) behind a floating piston (25).

Title: Improvements in flowmeters of the turbine type

Filed: 1964-12-07
Abstract: 1,023,247. Boundary layer control. S.A.T.A.M. S.A. POUR TOUS APPAREILLAGES MECANIQUES. Dec. 7, 1964 [Dec. 11, 1963], No. 49757/64. Heading F2R. [Also in Division F1] In a rotary flow meter of axial flow turbine type including a rotor having helical blades, the blades are divided in their axial direction by narrow slits into a plurality of sections. With unbroken blades of substantial length it is found that laminar flow breaks down and the resulting turbulent flow causes increased friction with consequent inaccurate meter readings. With the cutting of the blades into sections, laminar flow is restored on the leading edge of that section of blade downstream of the section on which transition from laminar to turbulent flow occurs to reduce friction. The range over which the ratio of fluid volume to rotor revolutions remains substantially constant is thereby extended to extend the range over which meter accuracy is maintained.

A colour imaging process comprises the steps of (a) providing a layer comprising a mosaic pattern having a plurality of contiguous, discrete small areas of different colour, each discrete area comprising electrically photo-sensitive particles of a single colour in an electrically insulating softenable material, (b) substantially uniformly electrostatically charging the layer, (c) exposing the layer to an image pattern of polychromatic light and (d) developing the layer by decreasing the resistance to migration of the particles through the material so as to allow imagewise migration of the particles through the material. An insulating solvent or vapours thereof may be used to soften the layer. A two colour layer may be made but preferably the layer contains particles coloured cyan, magenta and yellow. Many suitable pigments are specified. The softenable material may be copoly styrene-vinyl toluene but other materials are listed. The layer may be supported by a substrate of Cu, brass, Ni, Zn, Cr, stainless steel, Al, Cd, Ag or Au or paper, glass, plastics or rubber which is either conductive or conductively coated. The layer may be formed by dispersing the particles in the softenable material and applying the dispersion to a substrate by gravure rollers, a half-tone screen, electrostatic deposition or spraying to give a plurality of beads each of a single colour. The beads are formed into a smooth layer by passing a heated roller over them, softening the material with solvent vapour or by heating, or pressing without application of heat. The beads may be formed as a mono- or multi-layer and the substrate may be treated with a layer of softenable material prior to application of the beads.

Abstract: 1529719 Semiconductor pulse amplifier LICENTIA PATENT VERWALTUNGS GmbH 17 Dec 1975 [17 Dec 1974] 51649/75 Heading H3T [Also in Division G1]  To amplify pulse signals, e.g. in a wide-band repeater between optical transmission lines working up to gigabits/sec., each signal pulse of a train u s  interleaved between clock pumping pulses U p  charges a switching storage (step recovery) diode D 2  via a forward connected diode D 1 , the charge being removed by the following clock pumping pulse u p  via diode D 3 , producing an output voltage u L  across load resistor R L . A slight negative bias on u p  maintains correct operation of the Schottky diodes D 1 , D 3  between pulses. The width and hence the area of the constant voltage ouput pulse u L  is then related to the area of the signal pulse u s . In an embodiment (Fig. 4, not shown) 32-bit negative polarity words at 250 Mbits/sec from unit 40 are supplied as input u s  while narrow negative clock pulses, delayed by a variable delay line, are applied across voltage divider as pump u p , producing output pulses across a 50 ohm load resistor with half widths of 500 p.sec. Four independent signal trains may be multiplexed across a common load by combining four units as Fig. 1 with their respective signal and clock pulses delayed by successive quarter perods of 1000 p.sec. (Figs. 6, 7, 8, 9, not shown). The multiplex amplifier may be integrated on a ceramic substrate, possibly feeding as load a directly mounted injection laser biased above threshold and coupled to an outgoing optical waveguide (Fig. 5, not shown). The amplifier voltage amplification although charge is slightly attenuated, giving a nett power gain: the charge and current levels may be maintained by stepdown transformer coupling between cascaded stages (Fig. 10, not shown). The successive half clock period delays between stages, alternately fed from half-period staggered clock buses, enables the chain to function as a shift register in which case (Fig. 12, not shown) only an occasional transformer coupled pair of stages is necessary. A transmission line transformer loaded with ferrite rings (Figs. 13, 14, not shown) may be employed.
