Filed: 1946-05-03
Abstract: 611,754. Level-luffing jib cranes. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd., and KAY, I. May 3, 1946, No. 13546. [Class 78 (iv)] A level-luffing jib crane is constructed in accordance with the invention claimed in Specification 566,767, but the centre of gravity - CG (Fig. 2) is disposed rearward of the reference point L; the hoisting rope pulley S at the tail end of the jib AB is disposed so that a line B<1> joining the reference point L to the axis of the pulley S is canted upwards relatively to the line A joining L to R, the head pulley through a predetermined angle a; and the supporting points P, G at which the frame supports the jib AB are arranged to cause the point L to travel along path LJ inclined upwards and rearwards to the horizontal at an angle # where where n is the number of falls of the hoisting rope at the head of jib and n<1> is the number of falls of rope at the tail of the jib, so that the pulley at the tail end will move along a path inclined rearwards and downwards to the vertical at the angle alpha, and the centre of gravity CG will move horizontally. Fig. 3 shows the diagram of Fig. 2.carried into effect. Jib is composed of rigid structure AB<1> carrying pulleys RS over which the rope from hook T passes, and then passes backwards at N, to frame pulley U<1> and winch V. The jib is pivotally supported at Q by movable link O pivoted at P to frame W and is connected fixedly to links D which are pivotally connected to link F which pivots on the frame at G. Screw Y working in motor-driven nut Z is connected to link O at Y<1> and, by causing link O to pivot about P, luffs the jib. The extra link D gives rigidity. Angle # is calculated and is arranged to equal half the acute angle alpha between QR and QS so that hook 1 moves in a straight horizontal line, L being halfway between R and S. The conditions are likewise fulfilled if SL=“SR ; and if the rope N from S to V<1> passes again up to S and back again to U<1> and then to winch V so that #=¥alpha.

Abstract: 831,275. Mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. May 2. 1956 [May 27, 1955], No. 13575/56. Class 20(2) Pit props engaged with the mine floor and roof 'by springs or hydraulic pressure through foot and head pieces 16, 17, Fig. 1 also engage the floor and roof by means of plates 22, 30 at the foot arid head of the pit prop respectively, which are subjected to a force greater than the springs or hydraulic pressure and which is directed obliquely to the length of the prop so as to advance it towards the coal face. This force is supplied by hydraulic pressure acting in cylinders 19 on pistons 20 and inclined piston rods 21 connected to the plates 22, 30. The prop is moved forward until it is stopped by engagement with the plate 22 of the side of the recess 23, in which the plate 22 is constrained, and when the pressure in the cylinder 19 is relieved a spring 24 returns the plate 22 for another move. The prop 10 is hydraulic and engages cylinders 19 by universal joints 15. The pistons 20, rods 21 and plates. 22 may be pivotable about the longitudinal axis of the prop to vary the direction of advance. In Fig. 2 the prop has fork-shaped foot and head members 35, 36 engaging pairs of floor and roof bars 37 between which the prop engages the floor and roof by means of plates 53 adapted to be acted' on by pistons and cylinders 51 con-- nected by knife edge bearings 49 with the prop and plates 53 and arranged obliquely to the longitudinal axis of the prop. The movement of the props is limited by crossbeams 55 on the roof girders. The plates 53 and bars 37 are connected by rails 54 with a second prop. In ordter to allow relative movement between the upper and the lower parts of the prop the main cylinder 41 is arranged under a cylinder 43 which it engages by a rim 42 and the head member 36 engages over the cylinder 43 which it engages by a rim 45. In the second prop the lower fork also engages the cylinder 43 by a rim. The prop may be engaged with the roof and floor by a spring 48 or hydraulic pressure in the cylinder 41.

Title: Improvements in or relating to the combing of textile fibres
IPC: D01G23/06
Filed: 1958-04-29
Abstract: 838.923. Combing machines. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION. April 29, 1958 [May 3, 1957], No. 13641/58. Drawings to Specification. Class 120(1) [Also in Group XXXV] Wool fibres, after passing through a "Noble" type comb, are formed into an output sliver passing over tongued and grooved measuring rollers which move in response to variations in thickness of the sliver to operate a two-way switch. This switch is associated with resistancecapacity integrating circuits so that if the average thickness deviates beyond a predetermined value electromagnetic relays are operated to cause a reversible motor adjusting feed knives of the comb to run in the appropriate direction to correct the deviation. Such operation of the motor is made intermittent by a motor-driven camoperated switch which has further switches to ensure that it returns to a suitable starting position after the deviation has been corrected or after the comb has been stopped.

Abstract: 1,104,173. Friction gearing. HONEYWELL Inc. 31 March, 1965 [10 April, 1964], No. 13736/65. Heading F2Q. In a friction drive between driving (driven) wheels 17, 27, 37 and a driven (driving) sphere 10 universally rotatable in a system defined by three orthogonal first axes, three spherical idlers 12, 22, 32 respectively contact both the sphere, at three points lying respectively on the first axes, and the wheels, at points lying on second axes of the idlers respectively perpendicular to the first axes, and the rotational axes of the wheels are respectively perpendicular to both of the axes passing through the idler contact points and are parallel to different ones of the first axes. The drive is such that when drive is transmitted through any one of the idlers the other two idlers simply act as bearings only; i.e. with, say, drive from the wheel 17 to the sphere 10 through the idler 12, the sphere pivots on the point contact between itself and the idler 32 and the idly rotating idler 22 pivots on the point contact between that idler and the wheel 27. The sphere 10 may be a display ball having attitude indicative surface markings or he used as a hand control to apply desired attitude command signals to means controlling the attitude of a vehicle. The wheels may be driven by motors 18, 28, 38 through mechanical connections 19, 29, 39, or may drive generators. The drive may comprise six idlers all of which may be driven or three of which may act as bearings at all times. As shown, the sphere is supported on its three orthogonal axes, remote from the idlers, by three concave bearing pads 11, 21, 31 via bearing balls of air. The idlers are each supported by bearing pads such as the four shown. The idlers and wheels are of high coefficient of friction material.

Title: Improvements in or relating to Hydrostatic Devices
IPC: F16H43/00
Filed: 1968-03-21
Abstract: 1,171,563. Power-assisted hydrostatic steering mechanism. TRW Inc. 21 March, 1968 [6 Nov., 1967], No. 13770/68. Heading B7H. [Also in Divisions F1 and G3] A controller for power-assisted hydrostatic steering mechanism comprises a control valve 39 coupled to an input shaft 33 so as to be axially displaced upon rotation of the shaft and a positive-displacement control pump including a hypocycloidal gear set 51 and a rotary commutator valve 54. A torsion bar 81 connected to the shaft 33 and carrying a gear 89 meshing with internal teeth in the control valve 39 permits limited relative rotation between the shaft and valve so that a pin 93 projecting from the valve into a helical groove 91 in the shaft shifts the valve axially upon initial rotation of the shaft. A second pin 95 projects from the shaft 33 into a cut-out forming spaced abutments on the valve 39, whereby subsequent rotation of the shaft also causes rotation of the valve. A wobble shaft 64 has spaced toothed portions 67, 66 in respective engagement with the internal teeth in the valve 39 and with teeth formed in the inner gear element 53 of the pump. A projecting finger 63 on the wobble shaft 64 engages a radial slot in the commutator valve 54 to rotate the valve 54 around a pin 57 as the inner gear element 53 gyrates. Respective series of annular grooves formed in the control valve 39 and valve housing 36 co-operate such that upon rotating the shaft 33 in either direction pressure fluid supplied by an engine-driven pump 17 from a reservoir 27 to an inlet port P is metered by passing through the control pump 51 in the appropriate direction and in a quantity corresponding to the degree of rotation of the shaft 33, and is then directed through one of motor ports C1, C2 to the appropriate end of a double-acting steering ram 18. Fluid from the other end of the ram 18 returns through the other motor port C1, C2 and the valve 39 to a return port R communicating with the reservoir 27. In another embodiment, Fig. 12 (not shown), the input shaft and control valve are coupled by an elastomeric ring which is movably connected to the shaft for adjusting the neutral position of the valve, and additional annular grooves formed in the valve housing and supplied with pressure fluid through restricted passages reduce the effects of fluid leakage across the valve lands. The hypocycloidal gear set 51 and the commutator valve 54 are as described in Specifications 1,147,606 and 1,147,607.
