Abstract: 867,007. Gripping-devices. INDUSTRIE GLEITBAUGESELLSCHAFT AHL & CO. Dec. 31, 1959 [April 25, 1959], No. 44417/59. Class 78 (4). A lifting device for sliding formwork for concrete structures has two clamps, each comprising a jaw member 14, Figs. 1, 2, pivoted at 13, 18, and a wedge-piece 15, which grip a guide-bar 5 and are movable towards and away from each other. The upper wedge-piece is slidable in its jaw member, the amount of movement being limited by a spring 19, the pressure of which is adjusted by a screw 20. In operation an arm 10, connected to discs 9, is swung upwards about an eccentric pivot 8. Cheeks 12, attached to discs 9, are thus raised and carry upwards pivots 13 and the lower clamp 14, 15, allowing a lower spring 17 to expand. During this movement the frame 1, which supports the formwork, remains clamped to the bar 5 by the upper clamp. When the arm 10 begins to descend the lower clamp grips the bar 5 and the whole frame 1 is raised about the pivot 8. The upper clamp slides up the bar 5 and grips the bar at the end of the upward movement. The springs 19 and screws 20 allow a small downward movement of the frame 1 to occur at the end of each climbing movement. The ratio of upward to downward movement is preferably 3: 1. Fig. 5 shows an upper jaw member in which a leaf-spring 24 is mounted between the wedge-piece and the jaw member.

Abstract: 1,015,674. Valves. DES USINE CHAUSSON. S.A. Dec. 19, 1961 [Dec. 30, 1960], No. 45488/61. Heading F2V. [Also in Division F4] A combined pressure and relief valve assembly for water containers such as motor vehicle radiators comprises a cap 15 which carries a pressure relief valve member 26 urged by a spring 25 to a seating 7 in the filler pipe 4 when the cap is mounted thereon and a diaphragm valve 34 carried on the underside of the valve member 26 and having a core or nipple 37 to control an opening 32 in the valve member 26. The valve 34 opens to admit air when the pressure in the container or radiator is reduced. The valve 26 is moulded from a flexible plastics material having a Shore hardness of from 60 to 80. The diaphragm valve is made of a more flexible material and is connected to valve member 26 by sticking, by vulcanization, by its own resilience, or by the provision of a square profiled annular flange inserted in a groove in the valve 26 (Fig. 3, not shown). The cap 15 is moulded on to a metal cover 16. The cap 15 is attached to the filler pipe 4 which is integral with the radiator 1, by means of lugs 17 cooperating with ramps and notches in a dependent flange 14. A flat spring 23 is seated around a central stud 20 and abuts one end of the spring 25. The annular seating 7 borders an opening 2 in the radiator. When the pressure in the radiator reaches a predetermined value the spring 25 is further compressed and steam is emitted between the annular seating 7 and the valve member 26 to an outlet pipe 11 until the pressure inside the radiator falls. If the pressure in the radiator falls below the external pressure then air enters via pipe 11, traverses a slot or slots 33 in the stud 21, pushes out the nipple 37 and enters the radiator via openings 36. The surface of the diaphragm valve 34 exposed to air pressure in the opening 32 and that exposed to steam pressure are substantially equal. In a modification the cap may be secured to a hollow body 8 by turned-down lugs (Fig. 4, not shown) or by a locking rod (Fig. 6, not shown). In a further embodiment (Fig. 7, not shown) the cap is secured in a hollow body of plastics material which forms the seating for the flexible facing of the pressure relief valve. The body is screwed into a bush welded to the radiator.

Abstract: 1,200,688. Testing characteristics of circuit elements. SIEMENS A. G. Sept.26, 1968, No.45761/68. Heading G1U. To test whether a circuit element P has a required characteristic curve over a particular range a test signal U1 varying over that range is applied to the element P, and the resultant output U2 from P is applied to a network E having a transfer characteristic which varies in an equal and opposite manner to the expected variation in U2 so that if P has the required characteristic the output U3 of network E is substantially constant. A measuring instrument M is used to determine whether the output U3 remains between fixed upper and lower limits as the test signal Ul varies. In the example shown for testing the frequency characteristic of a filter, the network E comprises an amplifier having a frequency dependant feedback path, the test signal being swept over a required frequency range during the test. The meter M is a mirror galvanometer, and if, during the test, the light beam strikes upper or lower limit photodiodes F1, F2 a pulse is emitted which operates a control device St to reject the filter under test and give an audible or visual warning. If greater selectivity is required four limit-valve photo-diodes may be provided. In a sequential testing system each test cycle is initiated by the lower limit photo-diodeF2 which responds as the light beam first moves past it to trigger the generator G. Should the photo-diode not respond within a given period a timer unit T indicates that the test sequence has been interrupted.

Abstract: 1286115 Semi-conductor switches ENERGY CONVERSION DEVICES Inc 17 Sept 1969 [24 Sept 1968] 45852/69 Heading HlK A symmetrical switch comprises an element of GaS, GaSe, GaTe, InS, InSe, InTe or AlTe having two ohmic electrodes between which the resistance of the element is switchable from a high value to a low value by the application of a voltage above a certain threshold value. Reduction of the current through the element to below a holding value causes the element to revert to its high resistance state. The element may be formed by crystallization from a melt, in which case it occurs in polycrystalline or crystalline polymeric form. The ingot so produced may be cast or cut to shape or may be ground to a powder which is then pressed to the desired shape. Thin polycrystalline or crystalline polymeric layers may be produced by dispersing the powdered material in a carrier and applying by brushing, silk screening, printing &c., to a substrate, e.g. an electrode. The element may alternatively be sputtered from an ingot or from the constituent materials, in which case it initially adopts an amorphous form. Application of a relatively high potential across the electrodes causes a polycrystalline or crystalline polymeric path to form within the element between the electrodes, and this path then exhibits the switching characteristics in subsequent operation of the device. The electrodes may be made of W, Ta, Mo, Nb, stainless steel, Ni or Cr and may be applied by cold or hot pressing, vacuum deposition, sputtering or deposition from solution.
