Abstract: 891,915. Spot-type disc brakes. FORD MOTOR CO. Ltd. July 15, 1960 [July 15, 1959], No. 24775/60. Class 103 (1). Relative rotary movement between a pair of telescopically related brake members is converted into axial movement to draw them into or out of engagement with a reaction member. Member 102, Fig. 3, carrying circular pad 106 is rotatable within part 108 of housing 100 which is slidably mounted in a support 101 and locked against rotation by stud 122. The ends of a pin 118 in member 102, engage in helical slots 120, Fig. 4, in part 108 so that rotation of member 102 by lever 126 causes member 102 and arm 110 of housing 100 to move toward the disc 36. Friction pad 114 is carried by a retainer 112 which is adjustable. in arm 110 to compensate tor wear. The lever 126 may be rotated by a cable or hydraulic cylinder and the brake may be the service brake or be a parking or emergency brake used in conjunction with a fluid-actuated disc brake. This latter brake comprises circular pads 60, 62, Fig. 2, moved by pressure in cylinders 54, 56 against disc 36, the cylinders being formed in a housing 50 attached by bracket 76 to axle housing 14. The cast iron disc 36 is attached to a sheet metal stamping 42, 38, 34 attached by bolts 28 to wheel hub 16.

Title: Arrangement for Controlling a Resistance Welding Machine
Inventor: LORENZ ANTON
IPC: B23K11/25
Filed: 1968-05-23
Abstract: 1,189,913. Control systems for resistance welding apparatus. SIEMENS A.G. 23 May, 1968, No. 24778/68. Heading H2H. A resistance welding apparatus fed from a three-phase A.C. supply by way of back-to-back pairs of semiconductor controlled rectifiers and a welding transformer comprises means for controlling the rectifiers so that the welding current is in the form of a low-frequency alternating current and so that at the end of each of the half-cycles of the alternating welding current the rectifiers function as inverters to return to the A.C. supply the energy in the transformer whereby the trailing edge of each half-cycle of welding current has a much steeper slope than is normal. The rectifier pairs are furthermore controlled so as to produce a short period of zero voltage between successive halfcycles of welding current. The various portions of the welding operation, namely squeeze, weld, hold and off, are controlled by means which include pulse generators, pulse shaper circuits, counting and trigger circuits and a so-called programme controller, the means also including a number of "and" circuits. The pulse generators produce pulses, one in each half-cycle of the three-phase supply, so as to give two pulse trains, one positive going and the other negative going, with, in each train, a spacing of 120 degrees. Each of the portions of the welding operation has the duration thereof determined by counting the pulses so produced but during the inverter mode of operation of the controlled rectifiers the pulse counting is interrupted.

Abstract: 259,375. Fletcher, G. H., Brooks, R., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 5, 1925. Electric braking.-When two motors 1, 2 are arranged in parallel for electric braking, the armature of one motor by the closure of switches 15 - 18 is connected in the braking circuit with both field windings, while the second armature is either open-circuited or connected to impedance. After an interval which may be due to a second braking notch the controller or to a dash-pot device, the closure of a switch 14 connects the second armature to the braking circuit. The invention is applicable to a larger number of motors and a group of armatures.

Title: Improvements in or relating to Mowing Machines
IPC: A01D34/07
Filed: 1967-05-30
Abstract: 1,199,053. Mowing machines. C. VAN DER LELY N.V. 30 May, 1967 [17 June, 1966], No. 24968/67. Heading A1F. A mowing machine having two adjacent beams 38, 45 supported on a frame 1 and a coupling member 69 for connection e.g. to a tractor, is arranged so that the mower beams lie at the same side of the frame 1 during operation. An inner beam 9 is pivotally suspended from a lug 6 on the frame 1, a rear beam 16 pivoted at 14 and a pair of horizontal plates 11 pivoted at 10, 17, forming a rearwardly swingable parallelogram linkage frame. Brackets 19, 20 on the beam 9 pivot a retaining member 22, and a rod 24 mounts a compression spring 26, urging a slider 23 borne by the member 22 outwardly to engage a projection 27 in a recess of an arm 28, affording a "back break" safety linkage when the mower strikes an obstruction. Square-section housings 34, 34A depend from the plates 11, brackets 35, 39 bolted at their lower end mounting the inner mowing beam 38 for pivoting about pins 36, 43, the outer beam 45 being similarly mounted on the opposite sides of the housings 34, 34A. For adjusting the cutting height, the rear bracket 39 may be moved vertically by turning a screwed spindle 46 attached thereto, a slot 40 allowing movement of the bracket relative to its supporting bolt 41. The cutter blades of the beams 38, 45 are oscillated by connection to arms 63 projecting from a shaft 47 which is rotationally oscillated within the housing 34 by a crank arm 48, pivotally connected in turn to a pitman 49 driven by an eccentric crank pin 50 on a shaft (51) Fig. 2 (not shown), journalled in a bearing (52) on an upper beam 2 of the frame 1 and connected to the p.t.o. of a supporting tractor 73. The coupling member 69, Fig. 2 (not shown), comprises a horizontal beam (68) rigid with beams (70) converging upwardly to a bracket 75, and carrying plates 71 bearing pins 72. The bracket 75 is pivoted to the upper tractor lift link and the pins 72 engage with the lower links, while a horizontal stub (66) at the centre of the beam (68) forms a pivotal mounting for the frame 1. Locking bolts enable the frame 1 to be fixed to support the mower at a chosen angular elevation. For transport: The beams 9, 16 are turned rearwards through 90 degrees against the spring 26 by pulling a handle 96, and a link 97 is made fast for locking, Fig. 4 (not shown). To further reduce the mower width, on raising the mower on the tractor three point linkage a plate 82 is depressed by contact with the upper lift link, a pivoted linkage operating a piston 84 to transfer fluid from a cylinder 85 through a duct 89 to a cylinder 90, Fig. 3, raising the mowing beams 38, 45 about the pins 36, 43 by action on ropes 93 and arms 94.

A device for determining the thickness of a non-magnetic coating on a magnetic base' comprises a bar-magnet, 8 (Figs. 1 and 2), extended by a contact-making unit 11 of e.g. spherical or conical shape, which when placed on the test surface causes a change in the magnetic field associated with the magnet 8, thereby altering the angular position of a moving iron rotor 14, to which is attached a pointer 45 moving over a scale 46, the longitudinal axis of the bar-magnet 8 being inclined to the test surface. The plastic instrument case 1 is lined with a steel casing 2, having a window 4 to view the pointer 45. The barmagnet 8 is retained in position by a grubscrew 10, and the moving iron element 14, tapered and curved in a spiral, is suspended  near the mid-point of the magnet 8 on a shaft 15, which also carries the pointer shaft 36, and is attached to the free end of a planar hair spring 40, the other end of which is attached to a zero adjusting device operated by altering the tension on the spring 40 by the movement of an attached slotted member 62 effected by rotating an external milled wheel 69. A light metal vane 43 is also fixed to the shaft 15 and provides damping for the rotary movement 14. A normally engaging clamping mechanism is released by pressing a spring- loaded push-button 50 projecting through the front of the case 1, and the movement of the pointer shaft 36 is restricted - by two spring stops 59.
