Title: Improved carbon film resistor and method of making the same
IPC: H01B1/24
Filed: 1958-12-19
Abstract: 839,118. Resistance coatings. INTERNATIONAL RESISTANCE CO. Dec. 19, 1958, No. 41080/58. Drawings to Specification. Class 37. A resistor comprises an insulating base on to which is deposited a resistive film containing the elements carbon, silicon and oxygen covered by a further film having a higher oxygen content. The resistor may be made by decomposition of a gas or gases containing the elements to be deposited. In the embodiment described a ceramic base is placed in a vacuum chamber heated to the decomposition temperature of the gas or gases to be used, and the gas or mixture of two or three gases containing carbon silicon and oxygen is admitted, so that as they pass round the base a film containing the elements is deposited upon it. The gas first admitted contains a high ratio of carbon, so that a resistive film of required value is deposited, and then the ratio of the elements is changed to provide a gas having a higher oxygen content. The ratio may be changed by adding or increasing the amount of water, or in the case of two or three compound gases by decreasing the carbon containing compound. In a modification, an underlayer similar to the overlayer i.e. having a high oxygen content is first deposited on to the base before the high carbon content layer.

Abstract: 1509239 Linkwork MITSUBISHI JUKOGYO KK 9 Oct 1975 [5 Nov 1974] 41509/75 Heading F2K An excavating shovel arm 2 is carried at the rear of a tractor 1 by a member 3 which is movable along a transverse supporting slideway 6, 7 of the tractor 1 by a double-rod type double-acting hydraulic piston/cylinder unit in which the piston (not shown) has piston-rods 9 and 10 axially extending from each end of the cylinder 8 and in which the piston-rods 9 and 10 may be axially locked initially at the end of the rod 9 and finally at the end of the other rod 10 to provide a step-by-step movement alternatively of first the cylinder and then the piston and then again the cylinder to effect the total movement of the member 3 across the slideway 6, 7. The piston-rods 9 and 10 are each provided at their outer end with a transverse trunnion pin 11 and 12 by which the rods 9 or 10 may be releasably locked by one or other automatically operating latch devices 16 or 16<SP>1</SP>. The arrangement is such that starting at Fig. 9(A) the left hand end of the rod 9 is releasably locked at 16 whereby hydraulic energization at one side of the piston of the double-acting unit rightwardly moves the cylinder 8 and arm 2, 3 to the centre of the slideway as shown in Fig. 9(B). The latch 16 is then released and the hydraulic energization switched to the other side of the piston so that the piston and its attached rods 9 and 10 move rightwards to the position of Fig. 9(C) in which the right hand end of the rod 10 is releasably locked at 16<SP>1</SP> such that by switching the hydraulic energization back to the said first side of the piston the cylinders 8 and arm 2, 3 is again moved rightwards from the centre to the other end of the slideway to complete the total movement of the arm 2, 3 across the slideway 6, 7. Reverse movement, of the arm 2, 3 back to its starting point is simply effected by reversing the above procedure.

Title: Pressure responsive electric switch with time delay
IPC: H01H7/02
Filed: 1967-09-13
Abstract: 1,144,992. Pressure responsive switches. SQUARE D. CO. 13 Sept., 1967 [17 Oct., 1966], No. 41683/67. Heading H1N. A single or double pole snap switch 14 with a self-restoring push button 21 has its button operated by an actuating lever 22 pivoted at 24, one end of lever 22 being received in a groove in an operating stem 39 of a dashpot timer 34 as in Specification 1,068,896 and a central button 60 of lever 22 being engaged by an adjustable set screw 59 on an arm 56 of an operating lever 57 pivoted about a shaft (61, Fig. 6). Arm 56 is biased clockwise, Fig. 2, by a range spring (62, Fig. 6) to urge lever 22 to maintain button 21 depressed, and a base portion 65 of lever 57 is engaged by a stem 70 of a pressure sensitive bellows 74. Stem 39 is reciprocable and its movement is retarded inwardly (to the left, Fig. 2), but not outwardly, a screw 40 adjusting the maximum rate of inward movement of stem 39, so that switch 14 is not operated by momentary sharp increases in pressure. On such increases, stem 70 rises and rotates arm 56 anticlockwise (i.e. to the left, Fig. 2) against spring (62). An adjustable spring 80 determines the minimum pressure at which this occurs. The timer 34 is set so that, above a predetermined rate of change in pressure, movement of stem 39 and lever 22 to the left, Fig. 2, which is governed by timer 34, is slower than movement of arm 56 anticlockwise, so that arm 56 falls away from button 60 and switch 14 does not operate. Switch 14 operates normally if the sharp increase in pressure is maintained and on all pressure decreases. In an alternative arrangement (Fig. 7) there is provided a switch that is not operated by momentary sharp decreases in pressure by interchanging the positions of switch 14 with lever 22 and timer 34 relative to arm 56 of lever 57, the latter's position remaining unchanged. Timer stem (39) is still retarded inwardly (to the right, Fig. 7). On momentary sharp pressure decreases, stem (70) lowers and rotates arm (56) clockwise with spring (62) (to the right, Fig. 7). Movement of stem (39) and lever (22) to the right (Fig. 7) is slower than movement of arm (56) clockwise so that arm (56) falls away from button (60) as before.
