Title: Improvements in or relating to hand power tools
IPC: B25B21/02
Filed: 1970-12-11
Abstract: 1292537 Power tools ROBERT BOSCH GmbH 11 Dec 1970 [13 Dee 1969] 58842/70 Heading B3N A power tool comprises a drive motor and a drive transmission for imparting rotary impacts to a workpiece holder 28 and wherein a flywheel 18 mounted on a drive shaft 5 is rotatable by the drive shaft and is longitudinally located on the shaft by resilient members 24, 25 so as to be capable of axial oscillation and has impact dogs 26 engageable with impact dogs 31 on the workpiece holder by an axial displacement of the workpiece holder towards the flywheel. The flywheel is rotatably mounted on bushes 14, 15 which are non-rotatably mounted ted on shaft 5. Members 24, 25 are in the form of cup springs and provide a friction drive to the flywheel and also allow axial movement thereof. The impact dogs 26, 31 are shown in Fig. 2 where it is clear that the flanks of a dog are of different slope with the steeper flank being for unfastening a nut. There may be 4 or 8 equally spaced dogs on each of the flywheel and holder 28. If there are 8 such dogs then alternate dogs on each part have a shortened length to allow suitable engaging of the dogs during impacting. In operation the motor, having permanent magnets 7, is activated to drive the flywheel to a maximum speed, about 6000 r.p.m. The tool is then forced toward a nut connection which is engaged by holder 28. Spring 34 is compressed and the impact dogs meet. Full engagement of the dogs is impossible and the flywheel is forced axially away from the holder 28. Thus the holder receives a series of impacts and the flywheel oscillates axially as well as rotating. In an alternative embodiment, Fig. 4, a holder 128 and flywheel 118 are biased apart by a cup spring 152 having a characteristic whereby the spring force in relation to its compression increases to a maximum and then falls. A yet further embodiment is shown in Fig. 6 where a flywheel 218 and a holder 228 are biased apart by a spring 234. In operation to tool is forced toward a nut and the motor started. At a predetermined speed balls 259 are forced outwardly against an annular spring 260. Balls 257 also move outwardly so that spring 234 is compressed abruptly and the dogs come into engagement. The motor is designed to be driven by the direct current from a car battery.

Title: Electrical panel heater
IPC: H05B3/26
Filed: 1972-11-08
Abstract: 1366148 Panel heater J V H WREDDEN 8 Nov 1972 [22 Dec 1971] 59720/71 Heading H5H [Also in Division B5] A panel heater is produced by applying a parting film to a smooth support, e.g. a glass surface, having the required profile of the panel, placing on the parting film a first layer of chopped strand mat of E-glass fibre, placing on the mat a resistive element having a substantially uniform power output per unit area, flooding the first mat and the element with a liquid thermosetting plastics material, placing over the element while the liquid is still wet a second layer of chopped strand mat of E-glass fibre, flooding the second mat with the thermosetting plastics material, covering the second mat while the liquid is still wet with a second parting film, squeezing out air and excess liquid trapped between the two films, and leaving the assembly on the support, until the liquid has set sufficiently to allow the panel so formed to be removed without risk of damage and the parting films detached. Air bubbles and excess plastics liquid may be squeezed out manually, a margin of about 6 inches width of the parting films preferably being left around the edges of the mats and during the squeezing out, the margins being squeezed flat against one another to provide an air-tight seal around the assembly so that the risk of air being drawn back into it if the volume of liquid contracts during hardening is lessened. The resistive element may comprise a woven open mesh glass fibre fabric having deposited thereon a layer of graphite carbon or a carbon woven sheet or paper, and the parting film may be of Cellophane (Registered Trade Mark). Two resistance elements may be provided each having border electrode strips stapled to one pair of opposite sides and each provided with its own thermostat electrically connected in series with the element, terminals being provided in the panel for making external circuit connections. Each thermostat may be sandwiched between two small pieces of E-glass fibre mat, one of which separates the thermostat from the resistive element and the second of which separates it from the second chopped strand mat of E-glass fibre. The panel heater may be used in a processing tank.

Abstract: 1,272,140. Disc brakes. BENDIX CORP. 17 Dec., 1969 [31 Dec., 1968], No. 61421/69. Heading F2E. A brake actuator comprises a cylinder 18 having an open end adapted to be directed toward the friction face of a brake disc 8, a first piston 20 slidable in the cylinder toward and away from the open end thereof, a second piston 32 slidably mounted in the cylinder and a resilient means, e.g. Belleville washers 48, urging the piston 32 into engagement with the piston 20 and thereafter urging both pistons as a unit toward the open end of the cylinder. The piston 32 co-operates with the cylinder to define a cavity 30 adapted to be connected to a source of pressurized fluid, the force of fluid pressure in the cavity acting upon the piston to oppose the resiliency of the washers 48 and to permit movement of the piston 20 with respect to the piston 32 so long as pressurized fluid is admitted into the cavity. As shown, fluid introduced into cylinder 30 forces piston 32 to the left to flatten the washers 48, whereby a clearance will exist between the disc 8 and pads 12, 14. By introducing fluid in cylinder 18, the piston 20 operates to move the calliper 10 to the left to bring the pads into braking contact with the disc. When application of the parking brake is desired, fluid is exhausted from the cylinder 30 whereby the springs 48 force the piston 32 to the right to cause the stem 36 to bear on the adjuster assembly 54 and thrust the piston 20 also to the right so that the pads are applied to the disc. Rotation of a bushing 42 allows adjustment of the spring load.

Abstract: 740,007. Calculating-apparatus. BELL PUNCH CO., Ltd. Feb. 9, 1954 [Feb. 9, 1953], No. 3630/53. Drawings to Specification. Class 106(1). In a multi-bank key-set calculating-machine having additional figures marked on its totalizer wheels for checking purposes, means are provided for adding the checking figures and for indicating whether the sum is equal to the prime number forming the basis of the checking figures or a multiple of that prime number. The invention is applied to the machine described in Specification 713,484 in which the checking figures are based on the number 13. In the present machine, the highest (overflow) order is used for adding the checking figures, six actuating keys being provided for this purpose, and the corresponding totalizer wheel has 13 teeth. The zero position of this wheel is marked with a green star, which is visible after the checking figures have been added if their sum is 13 or a multiple of 13. This wheel is the fourth order wheel of that portion of the totalizer in which, as described in Specification 713,484, the checking figures are difference figures, and in this order, when the prime number is 13, each difference figure is the same as the normal totalizer number so that it is only necessary to show the latter even if this wheel is used as an overflow wheel as well as for adding the checking numbers. In an alternative arrangement, the 13-tooth numeral wheel may be arranged below, say, the lowest order totalizer wheel. In this case, when the checking figures are to be added, the 13-tooth numeral wheel is engaged with the totalizer wheel, the reading of which is ignored, by operation of the pushbutton which disengages the transfer mechanism between the two lowermost orders. Reference has been directed by the Comptroller to Specification 713,484.
