Abstract: 1,176,279. Endless conveyers. BARRY-WEHMILLAR CO. 6 Sept., 1968 [4 March, 1968], No. 42647/68. Heading B8A. Container handling apparatus in a bottle rinsing machine comprises a horizontally movable endless conveyer R to which container carrying pockets 60 are pivotally connected for movement about the pivots between vertically erect and pendent positions, first means 48 adjacent one portion of the endless path of the conveyer R to bring containers C into registration with successive pockets 60, second means 74 adjacent another portion of the endless path to receive containers C from the pockets 60 upon arrival, and pocket guiding means 61, 62 to first pivot the pockets 60 loaded with containers C into pendent positions to invert them, and later to restore the pockets 60 to vertically erect positions whereby the containers 60 are unloaded by the means 74. In the construction described, four conveyers R are fed by a single conveyer (15) (Fig. 14, not shown) via respective conveyers 18. Each of the latter lead on to a respective rotary table 21 associated with a star wheel comprising the first means 48. The sockets 60 are formed with respective apertures 60b (Fig. 9) to permit the entry of the containers C which then have their bases successively engaged by a cam 45a (Fig. 5, not shown) the purpose of which is to push them into the upper part of the pocket 60. The container is held in this upper position, throughout the rinsing operation, by a cam bar 67 (Fig. 4). The pockets are successively inverted by the action of cam rails 61, 62, which engage followers 59 respective to each pocket. An arm 58 carrying the follower 59 and rigid with the associated pocket 60 is pivotally connected to the conveyer chain 51 of the conveyer R. The rails 61, 62 are curved and their positions superimposed as shown in Fig. 4, thereby acting on the follower 59 to bring about the inversion of the pockets 60. The container is maintained in the upper end of the pocket by the action of the cam bar 67. While inverted, the containers are passed over rinsing jets 65. Similar means brings about the return of the pockets to their original attitude (Fig. 13, not shown). A cam bar (68), (69), corresponding to the bar 67 maintains the containers in the pockets during this operation and then allows them to fall into a position in which they are in register with the side aperture 60b of the pocket so that they can be guided by a rail 70 into pockets 73 of a recessed wheel 74. The latter feeds alternate pockets of a conveyer 23 which also serves another of the conveyers R. In a modification (Fig. 18), the follower 59 and cam rail 61, 62 are replaced by similar respective members 105, 106 and 107, but the cam 45, cam rail 67, and cam rails 68 and 69, are replaced by a control member 101 carried by each pocket 60. The member 101 engages the base of the container and pivots upwards to force the latter into the upper end of the pocket 60, by the action of a follower 99 and an associated cam rail 100.

Abstract: 1,062,981. Pulse radar. SPERRY GYROSCOPE CO. Ltd. March 16, 1962 [Dec. 16, 1960], No. 43355/60. Heading H4D. An aircraft is guided over ground obstacles by a pulse radar mounted in the nose. Signals are generated at the radar receiver when obstacles lying forward of the craft intrude within a predetermined threshold range. The signals activate the elevators to cause climbing. The rate of climbing is increased upon further intrusion of the obstacle by an integration term in the control loop. The radar antenna transmits and receives during alternate periods. The transmission is effected by a single narrow beam which scans in a vertical plane which includes the craft line of flight. During reception the directivity characteristic of the antenna is in the form of two overlapping, narrow, lobes in the scanning plane, and which produce two signals so as to provide an equi-signal plane perpendicular to the plane of the lobes. The received lobe signals form sum and difference signals, and the latter are either in-phase or anti-phase with the sum signals, which form a reference, according as the obstacle is below or above the equi-signal plane. Only those obstacle signals within a specified range are used to control the aircraft climb and this range is increased at scan angles above the equi-signal plane. Similarly, only anti-phase difference signals, corresponding to obstacles above the equi-signal surface are used.

Abstract: 874,531. Centrifugal pump impellers. A.E.I.- HOTPOINT Ltd. Dec. 31, 1959, No. 44451/59. Class 110 (1). A centrifugal pump impeller 3 comprises a hub 19 to which at least one blade is affixed, the blade(s) 18, at rest being inclined forwardly to the direction of intended rotation of the impeller from a plane containing the impeller axis and the location of the blade root, the blade(s) being so mounted or made of flexible material that as the speed of rotation of the impeller increases from zero to maximum the blade(s) 18 changes from its forwardly inclined position through the radial position II to a backwardly inclined position V. The pump impeller 3 rotates in a casing 1 formed by a removable cover 6 having an integral outlet 5 and a body member 7, having an integral inlet 9, said body member containing shaft bearings 11 and lubricant impregnated felt washers 12. At the position of rest the blades 18, which may be moulded integrally with the hub in indiarubber, are concave with respect to the direction of rotation and when running at relatively low speed the blades are fully extended, as at II. As the speed increases the pumping efficiency diminishes and the power required to drive the impeller increases more slowly than with fixed or rigid blades. The blades may bend against, and so be supported by projections 21 in the hub at the highest speeds. The pump is intended for spin driers wherein the maximum quantity of water to be pumped out occurs soon after spinning starts.

Title: Controller assembly for use in a vehicle steering system
IPC: B62D5/097
Filed: 1975-10-30
Abstract: 1519062 Power steering T R W Inc 30 Oct 1975 [6 Nov 1974] 45082/75 Heading B7H In a vehicle steering system of the kind described in Specification 45511/75, wherein the steering valve 10 is constructed for fluid communication with a steering motor 38, Fig. 4, a variable size orifice 42, formed between surfaces of a valve sleeve 16, Fig. 1, and a valve housing 12 is varied in accordance with variations in the rate of turning of input shaft 18 operatively associated with the valve sleeve and variations in steering load, the orifice 42 being in fluid communication via control port 52 with pressure responsive valve 56. The valve 56 effects operation of the motor 58 to vary displacement of pump 22 in known manner. As shown, in Fig. 1, input shaft 18, rotatable by a steering wheel (not shown), is connected via a torsion bar 75 with shaft 74 of metering assembly 62. The shaft 74 has gear teeth which mesh with the splines 78 on valve sleeve 16 allowing axial movement of the sleeve. A ball and helical groove arrangement 82 is effective to shift the sleeve 16 axially according to the relative rotation of shafts 18, 74, i.e. according to the torque applied to torsion bar 75. Axial movement of sleeve 16 to the left or to the right, according to the direction of rotation of the steering wheel, controls fluid between input port 26 and steering motor ports 30, 32. Fluid received from steering motor 38, Fig. 4, is conducted through the valve 10 via grooves 108, 112, 116 to control port 52 leading to pressure responsive valve assembly 56. Also, the fluid from motor 38 is conducted via grooves 116, 120, 124 through variable orifice 42, Fig. 3, to drain port 44 so that there is a a drop in pressure in advance of orifice 42 at groove 120 which results in a reduced pressure signal being conducted to valve assembly 56 resulting in increase displacement of pump 22 in known manner. If steering torque is reduced orifice 42 decreases in size resulting in a higher pressure signal communicated through conduit 54 to valve 56 resulting in a decrease pump displacement. In another embodiment, Fig. 7, fluid pressure from pump 22a, Fig. 8, is ported through a fixed orifice 42a to control port 52a, and through variable orifice 160 to drain port 44a. Therefore, when the valve is in neutral position there is a continuous pilot through fixed orifice 42a to establish a minimum standby pressure level at port 52a. In another embodiment, Fig. 11, fluid, pressure from pump 22b, Fig. 12, is ported through variable orifice 42b to control port 52b and also via a fixed drain orifice 249 which may be located either in sleeve 16b or housing 12b.
