Abstract: 1232215 Hydraulic reciprocating motors and pumps VON ROLL AG 5 July 1968 [7 July 1967] 32321/68 Heading F1A In a tilted or tilting head hydraulic pump or motor the drive plate is supported by a thrust bearing comprising a roller bearing and a hydrostatic bearing, the hydrostatic bearing being operative when the unit is working at highpressure. As shown in Fig.1, the hydrostatic bearing is formed by oil introduced for the cylinders (not shown) between a stater 14 and a rotor ring 13 by means of a throttle device, Fig. 5, duct 15, and an annular groove 16; the roller bearings 12 are dispersed between rotor rings 13 and 11. When the unit is operating at lowpressure the shear force of the oil exceeds the frictional force of the roller bearings and rotor ring 11 rotates relative to ring 13; at higherpressures, the frictional forces are reversed and ring 11 remains stationary while ring 13 rotates. In a variable unit Fig.2 (not shown) a stater is in the form of a bowl and supports a rotor ring, oil is introduced between their adjacent surfaces via bores having non-return valves, and channels from the external surface of the stater. The throttle device, Fig. 5, comprises a hollow piston 28; having a tapered portion 28, urged towards an infeed 30 by a spring 29. At low operating pressure oil flows into compartment 35 by means of a channel 32, compartment 33, and throughbored unit 34 with little throttling; at higher-pressures the oil undergoes more throttling. A measuring piston Fig.6 (not shown) may be arranged before the piston to reduce the size of spring 29.

Abstract: 1,256,971. Photographic processes for producing relief image. ITEK CORP. Jan.20, 1969 [Jan. 22, 1968], No.3206/69. Heading G2C. A photographic process for producing relief images comprises imagewise exposing a material comprising a support coated with a layer of a photo-sensitive substance in a binder, physically developing the latent image in the exposed areas until the layer becomes frangible and removable in these areas and then removing these areas. The specified photo-sensitive layer is titanium dioxide in hardened gelatine. In the examples, the photosensitive layer is coated on a subbed cellulose ester support, preferably soaked in silver nitrate, imagewise exposed, physically developed with a solution containing ferrie, ferrous and silver ions for four days and the exposed area slough off. Alternatively, they may be removed by washing, brushing or bleaching. The relief image may be used as a printing plate or as a master for diazo copying if a transparent support is used. A positive or negative of the original is obtained if the photo-sensitive layer or the support respectively are coloured black. Alternatively, the relief image may be uniformly exposed and physically developed to produce a reverse image which may be further amplified by copper plating.

Abstract: 1,264,822. Abrading grain; regulating malting. BREWING PATENTS Ltd. 5 June, 1970 [11 June, 1969], No. 29706/69. Heading A2Q. [Also in Division C6] Treatment of barley before malting consists in subjecting the distal ends of the grains to abrasion which renders the pericarp permeable to gibberellic acid but does not shatter the husk and pericarp. Thus, externally applied gibberellic acid can gain access to the aleurone cells remote from the embryo to accelerate the malting process, and the retention of the greater part of the husk allows the formation of a filter bed for the subsequent extraction of brewers' wort. In malting, the gibberellic acid may be applied to the abraded grains by being dissolved in the steeping liquor, or it may be sprayed on when germination is beginning. An apparatus for abrading the barley grains consists of a rotor D with wires &c. projecting radially from a cylinder F and of such length that a clearance of the order of 0.7 cm. exists between the periphery of the rotor and the inner surface of a housing A which has a replaceable lining of abrasive material or relies upon surface roughness for abrasive action. The rotor sets up a flow of air in the housing and impels grains, of which a charge is admitted through an inlet B, against the abrasive surface so that, it is stated, only the distal ends are abraded. After treatment, the charge is withdrawn through an outlet C for which, as also for the inlet B, closure means (not shown) are provided. In a modification, for treatment of a continuous flow of grains, the rotor and housing are elongated and a current of air conveys the grains from inlet to outlet. Other methods referred to for treating grains to allow ingress of gibberellic acid are rapid impaction of the grains without abrasive surfaces, and shaking the grains with sand.

Abstract: 1297400 Electric timepieces; automatic control of amplitude of oscillation H-U MEYER 17 Aug 1970 [25 Aug 1969] 39508/70 Headings G3T and G3R  In a timepiece, current pulses produced by a drive transistor T 1 , Fig. 1 through a drive coil L 1 , which is co-operative with a permanent magnet on an oscillatory member (not shown) e.g. the timepiece balance wheel, maintain  oscillation of the member. E.m.f. induced in a pick-up coil L 2 , due to movement of the magnet relative thereto, is applied via R 2 C 2  to the base of T 1  causing T 1  to conduct and produce a pulse through L 1  thereby increasing the speed of relative movement of the magnet and coil and hence amplitude of oscillation of the balance wheel. If the said relative speed is such that the e.m.f. induced in L 2  exceeds the threshold value of a regulating transistor T 2 , then T 2  conducts reducing the base/emitter voltage of T 1  tending to block it. The current pulse magnitude in the  drive coil L 1  will thereby be reduced, as  illustrated by curve 2, Fig. 5. Thereby regulation of the speed of the magnet and of the amplitude of oscillation is achieved. Curve 1 illustrates the drive pulse with T 2  blocked as would occur when the e.m.f. induced in L 2  is below the threshold of T 2 . In a modification, Fig. 3 (not shown) a diode replaces R 2 , C 2  - In a further modification, Fig. 4a (not shown) an NTC resistor shunts the base/emitter of T 2  to effect temperature compensation, while in a modification, Fig.4b (not shown) a Zener diode between the base of T 2  and coil L 2  is said to effect temperature compensation. A capacitor C 1  may be provided to eliminate parasitic oscillations. Capacitor C 2  functions to block D.C.
