Title: Pressure sensitive switch
IPC: H01H36/00
Filed: 1966-10-07
Abstract: 1,147,012. Indicating fluid-pressure, electrically. SUNDSTRAND CORP. Oct. 7, 1966 [Nov. 26, 1965], No.45031/66. Heading G1N. When fluid-pressure in a chamber 21 Fig. 2 exceeds a value (e.g. 100 p.s.i.), determined by a biasing compression spring 90, a piston 70 is moved against the force of the spring, and moves a laminated core armature 19 against a core 42 carrying an A.C. energized coil 40 thereby changing the inductance there of and altering its impedance from a low value when an air gap is greatest to a high impedance value when the two cores are together. The new value of the coil impedance may be such as to cause operation of a control device or indicator (not described). The armature core is carried by a shaft 54 which is coupled to the piston head 71 by a lost motion link including a pin 77 fixed to the head and slidable in a slot in the armature shaft, the piston thereby being free to move a greater distance than the armature, and a compression spring 80 within the piston urges the armature toward the core. The armature shaft 54 carries a permanent magnet ring 56 to collect undesirable metal particles held in suspension by the hydraulic fluid, which may leak past the piston from the chamber 21, which chamber may be in a constant speed drive housing (not described).

Abstract: 1276125 Pressure chambers ALLMANNA SVENSKA ELEKTRISKA AB 17 Sept 1969 [18 Sept 1968] 45736/69 Heading F4B A furnace for treating material at elevated temperatures in a gaseous atmosphere at superatmospheric pressure, comprises a pressure chamber and a furnace chamber 15 enclosed in a thermally insulating hollow body arranged within the pressure chamber and in spaced relation thereto, upper and lower gas flow openings being provided through the insulating hollow body to provide communication between the interior of the furnace chamber and the space between the insulating hollow body and the pressure chamber, the upper opening being normally obstructed by a member obstructing through-flow. In operation, when it is desired to cool down the furnace, the said member is opened by means of an externally applied impulse so that, influenced by the pressure difference due to the temperature gradients, gas can circulate from the furnace chamber and down through the space between the hollow body and the wall of the pressure chamber, so being cooled by the cooler walls of the pressure chamber. In the embodiment shown, a connection 30 is disposed in a space 29 above the lid 25 of the insulating sheath, said connection consisting of a tube 31 permanently fixed to an upper plate 32 of the lid 25 and an exchangeable part 33 resting on a support 34. The tube 31 opens into an annular gap 35 between a guide ring 28 and the lid 25. The gap 35 communicates with the furnace chamber 15 through a narrow annular gap 36. The part 33 consists of a metal tube 37 provided with an end plate 38 and two ears 39 for attachment to electrical conductors. Between the ears 39 is a groove 40 which forms a weak point and which facilitates melting of the end cap. When the tube has been melted by an appropriate electric current, the gas flows through the gap 36 into the space 29. Other embodiments include having an exchangeable spot 33 which is sealed by a membrane, or having mechanically operated opening means arranged to puncture a membrane on the application of an impulse.

Title: Clothes washer machine
IPC: D06F33/02
Filed: 1962-12-06
Abstract: 947,696. Washing machines. GENERAL MOTORS CORPORATION. Dec. 6, 1962 [Dec. 26, 1961], No. 46127/62. Heading D1A. In a clothes washing machine having a tub 16 with an overflow port 24, a temperature-responsive device 50 responds to the temperature of liquid overflowing from the tub 16 to stop the supply of water to the tub 16. For four minutes at the beginning of the cycle, one or both (depending on the positions of manually-operated temperature-selector switches) of two solenoids controlling hot and cold water inlet valves are energized through a timer-controlled switch across which the device 50 is connected. The device 50 may be a thermistor the resistance of which decreases with rise in temperature and which always carries a current which tends to keep its temperature high and its resistance low. When the timercontrolled switch is opened (after the four minutes), the solenoids are energized through the thermistor 50 alone. When the tub 16 overflows, the thermistor 50 is cooled and the resultant rise in resistance reduces the solenoid currents to close the inlet valves. Alternatively, device 50 may be a bimetallic strip switch kept closed by a heater when the timer-controlled switch is closed, but when the latter is open overflowing liquid from the tub 16 will cool the bimetallic switch sufficiently to open it and de-energize the solenoids. For rinsing, the solenoids are energizable through a second timer-controlled switch by-passing the device 50.

IPC: G01B5/20
Abstract: 470,246. Screw - thread gauges. WATKINS, D. M., and DILKE, W. E. April 21, 1937, No. 11341. [Class 106 (ii)] Comprises a method in which the work piece is inserted between a pair of similar uniform taut wires the operative portions of which are inclined at an angle dependent on the helix angle of the standard, one of the wires being supported by a member coacting with indicating means. The apparatus comprises a base 11 and upright 12. Upon the base is a block 13 held thereto bv a stud 14 and clamping nut 14a to be engaged by a spanner inserted at the opening 15. Adjustably mounted in the block 13 is a support 16 with a convex surface for a wire 17 the centre or operating portion of which stands proud of the block. The wire may be tightened by a small lever 20 operated by a nut 22. The wire is adjusted for helix angle by slackening the nut 14a and adjusting the block 13. The block 16 can be adjusted laterally by screws 23. The upper wire 28 is carried by a block 29 similar to the block 16. The block is fast with a stem 30 guided in a base of a bracket 31 adjustable on the upright 12. A U-shaped bracket 32 carried by the bracket 31 engages opposite sides of the block 29 to prevent it rotating about the axis of the stem 30. A nut 33 at the upper end of the stem 30 engages the plunger of a dial gauge 36 carried by the bracket 31. In use, the apparatus is first set up to a standard screw. This is done by choosing wires 17, 28 of a correct size and tightening them on the blocks so as to be parallel and arranged one over the other. Thereupon the standard is inserted the righthand end being inclined downwards, for a right-hand thread as shown in Fig. 6. The support is then moved to the right for a distance of half the pitch to bring the standard back to horizontal. It is passed to and fro along the wires until the highest reading of the gauge is obtained. With the standard in this position, the block 13 is set for helix angle until the wires drop as low as possible into the grooves of the thread, that is, until the gauge reading is a minimum and the standard is moved to and fro when in the position at which the highest reading is obtained, a back stop 24 is brought up to locate the back of the work piece and the screws all tightened up. The dial of the gauge is then set to zero and other screws substituted for the standard and departure from zero noted.

Title: Composite aluminium foil
IPC: B65D65/40
Filed: 1977-11-11
Abstract: The composite foil is sterilisable and is quickly ready to use and has a high chemical resistance, a long curing time thereby being avoided. The outer polyester film (2) is bonded to the aluminium foil (4) by a directly extruded polyester layer (3) which on the one hand increases the function of the sterilisable adhesive bond and on the other hand increases the thickness of the outer plastic layer of the produced package. The mechanical protection of the aluminium layer (4) against external damage is thereby effectively increased. The inner polyolefin layer (6) is now also bonded to the aluminium foil (4) by means of a polyester layer (5) applied by extrusion. Not only is the production thereby simplified, but also the security against damage to the aluminium foil from the inside is increased, which is important in particular when the packaged foodstuff contains hard parts, for example noodles or bone parts (in the case of ham). <IMAGE>
