Abstract: 400,033. Retractive switches ; snapaction switches. FELDMAN, J., 10, Flensburgerstrasse, Berlin. Jan. 17, 1933, No. 1509. [Class 38 (v).] In a snap-action switch attached to or mounted in the handle of an iron or other appliance and moved on and off by gripping the handle, the spring l, which moves over dead-centres to provide the snap action, serves also as a retractive spring tending to move the operating lever i into the "off" position. In the form shown in Fig. 1, the lever i is pivoted at i2 and the spring l is connected at one end to a bracket on the lever and at the other end to the contact h which is loosely mounted on the pivoted arm g. The switch may be held closed by pressing a plunger m<1> the inner end of which is adapted to engage a slot j<2> in the bracket j. To release this engagement the lever i is pressed down still further, when the plunger m<1> is moved back by its spring n ; on releasing the grip on the handle the lever i will now move upwards and open the switch. In a modification, Fig. 4, the arm g, instead of being pivoted to a fixed bracket, is pivoted to a lever p which has a slot p<1> in it adapted to engage and retain the bracket q on the lever i, when the lever p is raised into the position shown by means of its end portion r, or alternatively, Fig. 6 (not shown) by pressing on a plunger which bears on the lever p. Specification 400,032, [Group XXXVI], is referred to.

Abstract: 1,002,536. Storing liquefied gases. COUCH INTERNATIONAL METHANE Ltd. Jan. 15, 1962 [Jan. 13, 1961], No. 1533/61. Heading F4P. A method of externally-insulating a tank 10 for storing liquefied gas comprises fixing to the tank wall by temporary means, e.g. impact adhesive, and while the tank is at ambient temperature, blocks 11 of insulating material, e.g. polyurethane foam, the interstices of which are filled with freon gas, spaced at calculated distances from one another, filling the tank with the liquefied gas to bring the tank to its working temperature, and permanently securing the blocks in position, e.g. by bands encircling the tank, the calculated distances being such that upon thermal contraction of the tank when the latter's temperature is lowered to the working temperature, the gaps between the blocks close until the blocks are in contact with one another. The tank may be disposed in a vessel and before the insulation work begins the space surrounding the tank is sealed and the ambient temperature within the space is stabilized. The blocks 11 are preferably set with temporary spacers 12, e.g. of wood, and the spacing may be such that a bearing pressure will exist between adjacent blocks when the tank is at its working temperature. The bands encircling the tank preferably bear on the blocks through perforated-sheet metal spreaders; a vapour seal may be incorporated. The co-operating end faces of the blocks may be stepped or the blocks may be in two layers with the gaps between the blocks in one layer being staggered from the gaps in the other layer.

Title: Pneumatic percussion machine
Inventor: CAST ADOLF
IPC: E02D7/10
Filed: 1965-01-15
Abstract: 1,070,051. Nailing and stapling machines. K. REICH. Jan. 15, 1965, No. 1831/65. Heading B4C. A pneumatic percussion machine such as for nailing or stapling, comprises a percussion piston 4 controlled during its working stroke by a valve 21, means 7, 8 for returning the piston after its working stroke, and a holding device for retaining the piston in its rest position including an element 26 made at least partly from a rubber-like resilient material and adapted to interengage with a locking means 4<SP>11</SP>. The piston 4 is slidable in a cylinder 5 surrounded by a sleeve 6 so as to define an annular chamber 8 communicating with the space below the piston via holes 7. In operation, upon actuation of the valve 21, compressed air is fed via an inlet 17, chamber 16, passage 22 to act on the top of the piston until the pressure reaches a value at which the locking means 4<SP>11</SP> disengages itself from the resilient element 26 and thus causes a driver 14 to drive in a nail 13<SP>1</SP>. During the downward stroke the air below the piston is forced via the holes 7 into the chamber 8 where it is compressed so that when the valve is closed, the piston is returned to its rest position. In a modification, the resilient element 26 is replaced by a resilient ring located in a groove in the piston and engaging with a groove formed in the wall of the cylinder. In the modification shown in Fig. 3, the resilient element is formed with a flange 236 secured to a piston member 237 which in the rest position of the machine is acted upon by compressed air via a port 257 and pipe 254 so as to force the flange 236 into contact with the end of the cylinder. When the valve 256 is actuated, the flow of air to the piston 237 is cut off, thereby allowing the flange to lift away from the end of the cylinder and so cause the percussion piston to be driven downwardly; the air above the piston is prevented from escaping to atmosphere by means of a pin 243 engaging in a hole 242 in the element 236. In a further embodiment (Fig. 5) the resilient element (326) is adapted to be expanded into locking engagement with the percussion piston 304 by means of air fed into the interior of the element via a pipe (354) and a port (363) in a pin (366).

Abstract: 1,004,542. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 16, 1964 [Jan. 25, 1963], No. 1907/64. Heading H1K. [Also in Division H3] An elongated PIN body 1 carries on its intrinsic portion 2 two electrodes 6, 7 of P or N type so that, with the application of suitable bias potentials, a phase shift of 360 degrees is produced between an input signal at terminal 16 and an output signal at terminal 17, feedback between these terminals, Fig. 1, producing sinusoidal oscillations. The frequency of oscillation varies according to the bias potential applied to a third P- or N-type electrode 5. If this bias potential is varied sinusoidally, the device functions as a frequency modulator. A plurality of elements 1 may be connected in a chain to form a delay line, Fig. 2, the output terminal 17 of each stage being connected to the input terminal 16 of the next. The phase shift, and hence the delay, at each stage may be altered by altering the bias potentials applied to electrodes 5 and 6.

Title: Safety device for vehicles such as tractors and the like
IPC: E02F9/24
Filed: 1961-01-17
Abstract: 911,935. Engine stop-gear. WATSON, R. B., and AUSTIN, C. G. Jan. 17, 1961 [Jan. 21, 1960; Sept. 5, 1960], No. 1916/61. Class 122 (4). A safety device for vehicles such as tractors and the like comprises electrical switching means adjustably mounted on the vehicle and adapted to be operable on a tilt of the vehicle beyond a degree predetermined by the maximum angle of stability of the vehicle in any direction, the switching means co-operating with the power unit of the vehicle to stop the power unit when the predetermined degree of tilt is reached. Referring to the Figures, as soon as the vehicle tilts to such an angle that one or more of the contact units 4a to 4d complete a circuit over their electrodes the current flows from the battery over the ignition switch I.S. and one or more of contact units 4a to 4d through the thermoelectric relay 23 to earth as long as the closing of the circuit via the contact units is only of short duration the thermo-relay will not operate. Thus short jolts or vibrations will not stop the engine. When, however, the vehicle remains on a certain tilt for a longer period the thermoelectric relay will heat up and close its contact 23a. The circuit of the cut-out magnet 18 is thus completed. Thus the magnet 18 operates and breaks contact 19, thus interrupting the ignition circuit and stopping the engine. To extricate the vehicle from the tilted position the operator can re-establish the ignition circuit by pressing the push-button 3 and holding it in the operated position until the vehicle has reached again level ground. In the case of a diesel engine the magnet DF is energized to cut off the fuel supply whenever the cut-out magnet 18 is operated. Each of the contact units consists of a glass tube 5 (Fig. 2) having two electrodes 6 and 7. The glass tube 5 is partly filled with mercury 8. When the glass tube is tilted the mercury will bridge both electrodes. It is possible to use bent glass tubes for the contact units or place the electrodes in other parts of the glass tube to increase immunity against unwanted operation and in some cases the thermo-electric relay may then be dispensable. The invention is applicable to bull-dozers.
