Filed: 1971-11-03
Abstract: 1321344 Inertia switches EATON CORP 3 Nov 1971 [4 Nov 1970] 51184/71 Heading H1N In an inertia operated electric switch a mass 66, Fig. 4, slidable between guide faces 90, 91 of a housing 10 is resiliently held by spring blades 72 surrounding the edge of the mass and arranged to provide a variable spring rate as the mass 66 moves. The arrangement is such that one or more of the blades 72 completes an electric circuit between a fixed terminal 102 and an annular contact 84 but that as the mass 66 moves it slides past some of the blades 72, Fig. 5, whereby a reduced resistance to motion is obtained. The blades 72 are however attached to a sloping ledge 104 so that they extend towards the mass 66 and are curved back whereby each blade 72 remaining in contact with the mass 66 has an end 72a engaging or extending towards the contact 84 at an angle to -provide for some sliding movement of the end 72a following the abutting contact movement and also to provide for a further variation in the spring rate with movement of the mass 66. The blades 72 are also so arranged that a circuit is closed if the mass 66 moves to one side of the direction shown in Fig. 5. In the example the switch is arranged in a motor vehicle to operate an explosive charge which releases pressure fluid to inflatable bags for protection of the occupants after a collision. In other examples Fig. 6 (not shown) the mass 66 may have an insert which normally closes an electric circuit, whereby each of the ends of the circuits to the explosive charges is earthed and prevents inadvertent operation by electrical interference &c.

Abstract: 1,113,296. Knitting-machines. WILDT MELLOR BROMLEY Ltd. 28 April, 1967 [7 Feb., 1966], No. 51764/65. Heading D1C. A patterning mechanism for a multifeed circular machine comprises at least two coaxial pattern wheels so arranged and operated that while one is selecting needles the pattern in the other or others is or are being altered. The needles (not shown) in tricks 1a of cylinder 1 are raised by jacks 2 with a spring end 2a having a butt 2b normally in the path of a lifting cam 3. The height of selector packs 4 is controlled so that one of its two butts 4a, b may be influenced by coaxial wheels 5, 6 respectively which are driven by gearing 9, 11 from the cylinder 1. In one embodiment bits 14 having butts 14b at one of four levels alternately, slide vertically in the tricks. Bolt cams 16 having inclined faces, and selectively operated by solenoids S1-8, adjust the height of the bits so that selected operating butts 14a are clear of jack butts 4a, b, when the wheel is operative, unselected bits strike the selector jacks, and force the jack butts 2b behind cam 3. The bits of the. other wheel are returned to the operating position by cams 17 or 18 acting on butts 14a, and groups having butts at a common level are re-set seriative, by their solenoids. Resetting may be achieved during one or more revolutions of the needle cylinder. In modifications the bits may be pivotally mounted in the wheels;, the height of the wheels may be adjusted relative to the selector jacks; and the bits may act directly on the needles.

Filed: 1965-12-09
Abstract: 1,124,967. Optical scanning system. K. S. PAUL & ASSOCIATES Ltd. 9 Dec., 1966 [9 Dec., 1965], No. 52418/65. Heading H4F. The Specification relates in general to an optical scanning system using the output half of a double Gauss lens system whereby for irradiating a flat surface with a light beam, parallel rays are all focussed thereby on to said surface irrespective of their angle of incidence on the lens, and for scanning an illuminated or radiant flat surface, all points on said surface produce a corresponding parallel beam from said lens. In an example of the former application a parallel beam of light is produced by a continuous laser 1 and lens 10 and is caused to move angularly to describe a desired scan by means of a mirror 2 rotating about orthogonal axes 6-7 and 8-9. The moving parallel beam is incident on the output half of a double Gauss lens system 3 at various angles and is focussed on a flat surface 4. Various other applications of the scanning system are referred to.

Title: Improvements in and relating to light filters
IPC: G02B5/28

Abstract: 1,061,319. Optical filters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 10, 1965 [Dec. 18, 1964], No.52430/65. Heading G2J. A light filter 14 comprises a plurality of partially transparent spaced layers 18 of silver chloride disposed within a member of transparent material, the layers being spaced so that (i) along any line normal to one of the two outer layers the spacings between the layers are substantially equal, (ii) the size of the spacings taken along a series of lines normal to a particular line varies progressively along said particular line, and (iii) coherent reflection occurs for light of different frequencies when directed along different ones of said series of lines. The filter is formed by setting up standing waves of a beam of monochromatic light in a photographic emulsion containing silver halide, thereby depositing silver at the antinodes of the waves, the intensity of the beam varying from one edge to the other. The emulsion is developed, a fixer causing it to shrink and hence causing the spacings between the layers of the deposited silver (later treated with mercuric chloride) to vary according to the intensity of the light directed over the surface. When light directed at any point on the surface of the developed emulsion is at such a frequency that its wavelength is twice the distance between adjacent reflecting layers beneath that point, a coherent reflective scattering of light is obtained. A scale (50) Fig. 6 (not shown) may be provided along one edge of the film (14) to indicate the frequency at which light is reflected from the film, which may be used as a frequency generator Fig. 4 (not shown) or to identify an unknown frequency Fig. 5 (not shown).

Abstract: 1,255,307. Lubricating. WESTINGHOUSE ELECTRIC CORP. 9 Nov., 1970 [28 Nov., 1969], No. 53197/70. Heading F2A. [Also in Division F1] A turbine installation includes a lubricating system comprising an oil reservoir 48 from which oil is led by conduits 46, 34 to bearings 18A- 18D, 28A-28D; hot oil from the bearings is drained to a tank 60 and pumped by an electric pump 62 to a heat exchanger 64 and back to the reservoir; between an upper part of the reservoir and the tank is provided an overflow conduit 71. If a generator 26 driven by the turbine is overloaded and the whole installation is shut down, the turbine can be started by a  device 30, but in these circumstances no power is available to operate the oil supply system. A D.C. pump 50 is therefore used to pump oil to the bearings, and, since the oil cooling circuit will be out of action until the generator is operational, hot oil drains back to the reservoir via the conduit 71 where it is diluted by the large volume of cold oil present. In a modification (Fig. 2, not shown), baffle plates are positioned in the reservoir between the opening of conduit 71 and the D.C. pump inlet.
