Title: A hydraulic control system
IPC: F15B11/17
Filed: 1969-11-12
Abstract: 1,263,118. Hydraulic motor control circuits. DEERE & CO. Nov. 12, 1969 [Nov.13, 1968], No.55318/69. Heading F1P. A hydraulic actuator 23, Fig. 1 is supplied through a distributing valve 18 by a variable delivery pump 10 until such time as the flow demand of the actuator increases to a predetermined value when the actuator is also automatically supplied by a fixed displacement pump 11 controlled by a valve 25 whereby its output is either zero or at a constant maximum value. With valve 18 closed the pressure rise in a branch line 17 of the delivery line 16, 19 of pump 10 is transmitted through a line 44, a housing bore 42, Fig. 3 and a recess 43 to a cross bore 40 in the hollow valve spool 33 so as to react against a piston 41 to move spool 33 against a spring 34. This results in a branch 45 of the delivery line of pump 11 being connected via a filter 47, Fig. 2, housing recess 29, spool groove 55, housing bore 31 and a line 32 to the drive chamber of pump 11 thereby disengaging a driven cam from the pump piston. Also the pump delivery line 45 is connected to the return reservoir 12 through a housing orifice 61, a bore 58, orifice 62, housing bore 50 and a line 51 and the line 45 is also connected through bores 50, 60 to a chamber 28 thereby assisting pressure in bore 40 in holding the valve spool in its left hand position. On opening valve 18 the shoal 33 will remain in its L.H. position so long as the actuator demand does not exceed the flow capacity of pump 10 and when the demand increases the resultant pressure drop in line 17 causes valve spool 33 to be returned to the R.H. position shown whereby fluid in the drive chamber of pump 11 is exhausted to reservoir 12 through line 32, housing bore 31 grooves 55, 30, spool bores 54, 53, 52, housing bore 50 and line 51 thus rendering pump 11 effective to assist pump 10 in supplying the actuator 23.

As described seven bit representations of characters to be printed are read into a core store 10 consisting of seven matrix planes each having a number of storage locations equal to the number of print hammers in a line, in this case 150. Each time the type belt moves through one character position the contents of the store 10 are read out for comparison with representations of the characters under each print hammer under the control of counter 12. A number of additional planes 15-18 are provided and are addressed in the same sequence on the main store 10. The planes 17 and 18 act as a binary counter to time the operation of the hammers.  Each addressing cycle of the store is divided into " major " and " minor " parts in which corresponding locations in two halves of the store are addressed. Thus the locations associated with a particular hammer in the additional planes 17 and 18 are accessed every half cycle of the store addressing sequence. Thus corresponding locations in the additional planes store 1, 1 when 2À5 scans of the main store have been completed. At this point actuation of an actuated hammer is discontinued. Different hammer actuating periods may be achieved using more additional planes and/or by changing the relative positions of locations in the main store addressed in " major " and " minor " parts of a store access cycle.

Abstract: 1,201,400. Knitting; stitching fibrous materials; finishing fabrics. VYZKUMNY USTAV PLETARSKY. 30 Dec., 1968 [3 Jan., 1968], No. 61636/68. Headings D1K, D1R and DIS. A fibrous mat has a sequence of warp knitted stitches extending in a walewise and coursewise direction knitted through it so as to produce a pattern effect caused by the protrusion of the fibres from the composite fabric at positions extending between the stitches. The effect is prominent on both sides of the fabric, the knitted loops appearing on one face and the connecting loops between the stitches occurring on the other side. The pattern effect may be caused by the warp knitted structure being of a tricot stitch or other formation in which knitting occurs on needle groups over a series of wales and courses, the grouping of the needles being rearranged after each series of courses. The relief pattern can be made more conspicuous by using in the basic layer at least two sub-layers made from materials of different potential shrinkage. The fabrics are then shrunk by heat or chemically such that differential shrinkage occurs whereby the less material causes this sub-layer conspicuously to bulge out in the space between the groups of wales.

Class 80 (ii) [Also in Group XXXII] A resilient connection comprises two concentric tubes 1, 2, bonded together by opposed pads of rubber 3, such that relative radial movement of the two elements in a direction at right angles to the diametral centre line of the pads is initially resisted solely by stressing the rubber in shear. The tubes may be axially displaced during bonding and brought into line when mounted to prestress the rubber. One or both pads may have an integral layer of rubber 3a bonded to a peripheral surface between the pads to limit, by compression relative radial movement of the tubes. The connections are shown employed as resilient bushes circumferentially spaced in the flanges of a resilient gear wheel, and in Fig. 5 they are spaced with their axes radial to connect a gear 17 on a quill 18 to an axle 19. The connections are mounted on the brackets 20 rigidly, driven from the gear 17, and the outer tubes are rigidly or slidably held between a driven member 21 and a clamping ring 22.
