Title: Vehicle controls
IPC: F16H63/24
Filed: 1973-01-24
Abstract: 1370771 Controlling vehicles MASSEYFERGUSON Inc 24 Jan 1973 [27 Jan 1972] 3557/73 Heading B7H A control system for a vehicle, e.g. a fork lift truck, includes a pair of pedals 24, 26, a first linkage 47 connecting the pedals 24, 26 to a transmission control element 28 which is movable to select either forward or reverse drive and a second linkage 45 connecting the pedals 24, 26 to accelerator means, e.g. for an I.C. engine, the arrangement being such that initial movement of pedal 24 (from position A<SP>1</SP> to B<SP>1</SP>) actuates the linkage 47 to select forward drive and further movement of pedal 24 (from position B<SP>1</SP> to C) actuates linkage 45 to accelerate the engine and corresponding movement of pedal 26 initially selects reverse drive and then accelerates the engine. Preferably movement of either one of the pedals 24, 26 does not impart movement to the other pedal. As described the pedals 24, 26 are rotatably mounted on shaft 44 and are held in position A<SP>1</SP> by springs 100. Each pedal 24, 26 carries a cam 46 which engages a follower 72 carried by a lever 76 rotatably mounted on shaft 78. Initial movement of either pedal 24, 26 from position A<SP>1</SP> to B<SP>1</SP> causes the corner portion 96 of cam 46 to move the corresponding lever 76 from position A to B. The end portion 94 of each cam 46 is of constant radius so that further movement of the pedals (from B<SP>1</SP> to C) does not impart further movement to the lever 76. The levers 76 are connected by links 82, 84 to a U bracket 30 on opposite sides of pivot 70 for bracket 30. The bracket 30 is connected at 32 to transmission control element 28 so that initial depression of pedal 24 selects forward drive and initial depression of pedal 26 selects reverse drive. At position B<SP>1</SP> each pedal 24, 26 engages a cross-bar 50 fixed to bracket 48 pivoted to shaft 44. The bracket 48 is connected by links 52, 64 to the engine accelerating means so that movement of either pedal from position B<SP>1</SP> to C causes the engine to accelerate. The links 82, 84 are connected to bracket 30 by springs 90 so that if both pedals 24, 26 are depressed simultaneously, both springs 90 stretch and the tranmission remains in neutral, further movement of both pedals 24, 26 then causing the engine to accelerate without the vehicle moving.

Title: Dispensing of particulate materials
IPC: B65G65/48
Filed: 1974-04-19
Abstract: 1464856 Dispensing materials R H LEE 19 April 1974 [24 Jan 1973] 3638/73 Heading B8S Apparatus for dispensing a particulate material comprises a frusto-conical chamber 1 having a sleeve 11 to which a cylindrical tube 12, which contains the material to be dispensed, is attached by means of clamp screws 15, the chamber 1 and tube 12 being rotatable relative to a plate 3 which is fixedly mounted on a fixed shaft 5, the material passing from the tube 12 through an inlet 4 in the plate 3 into the chamber 1 from which it is dispensed at an outlet 2. The portion 7 of the wall of the chamber 1 which at any instant is lowermost is either horizontal as shown, or else slopes upwardly at a small angle towards the outlet 2. A baffle plate 6 which is fixedly mounted on the shaft 5 reduces any tendency of the material to surge, and a brush 9 is mounted on the shaft 5 and engages the inner wall of the chamber 1. The rotation of the chamber 1 and tube 12 is effected by an electric motor (16) which drives a pinion 14 which meshes with a gear-wheel 13 fixed to the sleeve 11. In the embodiment of Figs. 3 and 4 (not shown) the material-containing tube (20) is non- rotatable, while the frusto-conical chamber (23) is rotatable. An end plate (24) is attached by means of ties (25) to the chamber (23). In the embodiment of Fig. 5 (not shown) the material outlet (32) is provided in the wall of the frustoconical chamber. In the embodiment of Fig. 6 (not shown) the frusto-conical chamber (40) and tube (41) are rotatable about a pivot axis (42) to enable the rate of flow of material to be varied through the outlet (43).

Title: Method and apparatus for determining the cross section of filamentary or wire-form material
IPC: B65H63/06
Filed: 1973-01-25
Abstract: 1396242 Acoustic inspection devices ZELLWEGER Ltd 25 Jan 1973 [15 March 1972] 3816/73 Heading H4D A measure of the cross-section of filamentary or wire-form material is obtained by establishing acoustic standing waves of at least two different frequencies, passing the material through a region in which both a pressure maximum of one frequency and a pressure minimum of another frequency occur, and sensing any change in the apparent wavelength of the waves, by means of at least one sound pick-up, as a result of introducing the material into the region. It is stated that the use of two frequencies enables the disturbing effects of temperature or atmospheric contamination to be compensated on the basis that introduction of the material increases the transit time for one frequency but decreases it for the other, whereas the disturbing effects change the transit times for both frequencies in the same sense. In the various embodiments described, two harmonically-related frequencies are generated either simultaneously or successively. For successive generation, a loud-speaker and microphone facing each other may be set in parallel reflecting surfaces, the microphone being switched to the inputs of a phase-inverting amplifier and a non-phase-inverting amplifier alternately, the loud-speaker being driven by the amplifier outputs. For simultaneous generation a separate loud-speaker/microphone pair may be used for each frequency, or, if the two frequencies are respectively an odd and an even harmonic of some fundamental frequency, they may each be fed to two loud-speakers arranged facing each other and detected in two microphones facing each other, the odd harmonic being separated out by subtracting the two microphone outputs and the even harmonic being separated out by summing the outputs. The cross-section measure is obtained from the amplitude or phase of the microphone signals and is indicated or recorded or is used to give an indication of the mere presence or absence of the material.

Title: Double throw co-axial electric switch
IPC: H01P1/12
Filed: 1961-02-01
Abstract: 908,545. Electromagnetic switches. DONLAN ELECTRONICS Inc. Feb. 1, 1961 [Feb. 1, 1960], No. 3878/61. Class 38 (5). An electromagnetic change-over switch for connecting high-frequency coaxial connectors includes a rockable contact assembly dynamically balanced with respect to its pivotal axis. As shown, a block 21 is pivoted on and electrically connected to the end of the inner conductor 20 of the input connector 11 and has secured thereto a flexible contact reed 24. The block 21 and spring 24 form the dynamically balanced assembly and are biased anticlockwise by a spring 30 urging a plunger 29 against a face 23 of the block 21. On energization of a coil 27 an armature 26 moves a plunger 25 downward against a face 22 of the block 21 to rotate the block against the bias so that the reed 24 disengages a contact end 18 of the inner conductor of an output connector 12 and engages a contact end 19 of the inner conductor of an output connector 13. The extreme positions of the block 21 are such that the spring 24 is stressed in both positions. The outer conductors of the connectors 11, 12, 13 are electrically connected by the casing 10.
Patent GB-896014-A (GB)
Title: Improvements in or relating to the impregnation of sponge-like material
Filed: 1958-02-06
Abstract: Sponges, for example of rubber or resilient plastic material such as polyester diisocyanate, are impregnated with detergents in liquid, paste or powder form by applying a predetermined quantity of detergent which is not more than the volume of the cells of the sponge to one surface of the sponge, and then forcing the detergent into the cells of the sponge by means of pneumatic or mechanical pressure applied to that surface.  The pressure exerted may be produced by placing a rectangular block of the sponge material in a mould having a wire grid or other perforated base, beneath which is connected a vacuum tank.  Viscous detergent solution is then applied to the upper surface of the sponge and the reduced pressure applied to the under surface of the sponge so that the detergent is drawn into the sponge.  Alternatively, the sponge is placed in a similar mould supplied with a piston instead of a source of reduced pressure. Air is forced from the sponge by the piston and the detergent is sucked into the sponge by its subsequent expansion.  Yet again, the sponge may be placed upon a rigid surface and compressed by a wire grid or other perforated surface, the detergent, which is applied to the compressed upper surface, being sucked into the sponge when the compression is released.  After treatment, the sponge may be cut into relatively small pieces.

Title: Gauges for monitoring liquid levels
IPC: G01N27/07
Filed: 1973-01-26
Abstract: 1347669 Electro-physical measurement - liquid-level GUSTAV F. GERDTS K G 26 Jan 1973 [2 Feb 1972] 4032/73 Heading G1N In a liquid-level gauge the electrode 6 is mounted on an insulator making a fluid-tight seal with a bore in the container wall 1. The insulator comprises several mica discs 8 surrounding the electrode with interposed distance sleeves 9 insulated from the electrode e.g. by an annular gap 10. The parts are compressed by a nut 14 against a shoulder 11 on the electrode, and two of the discs form a seal against the partition 3. The distance pieces 9 may be metal. This construction is especially suitable for alkaline liquids which attack ceramic and porcelain insulators. INTERNAL LEAKAGE may be detected by a further electrode (not shown) in the annular gap 10 or by using one distance piece as a detector electrode, or by packing the gap with dry salt which provides a low resistance when moist and so provides an abrupt change in the signal. SURFACE LEAKAGE on the insulator may be compensated by using one of the distance pieces as a compensating electrode, with a common tubular counter electrode surrounding the distance piece and the "level" electrode. The series  resistors thus formed are connected in a bridge circuit so that the leakage signal opposes the "level" signal.

Abstract: 464,947. Exhaust and like silencers. SERVAIS, N. H. Feb. 11, 1936, No. 4109. Addition to 447,376. [Class 7 (ii)] The silencer described and claimed in the parent Specification, and comprising a casing having a composite filling of fine fibrous material held together by a more rigid openwork material so as to leave a substantially unobstructed passage for the gases, is modified by forming the composite filling so that the openwork material defines the passage for the gases from the inlet to the outlet of the silencer and also extends into the body of the fibrous material in planes transverse to the axis of this passage. The Figure shows the filling composed of a series of annular discs 20 each formed of a mass of fibrous material, such as steel wool, glass wool, or asbestos fibre, and surrounded by the openwork material, such as expanded metal or wire netting. In another form, the filling is made of a rope of fibrous material enclosed in the openwork material, the rope being coiled into a helix. Again, the filling may be made up of a number of short flanged tubes of openwork material arranged so that the flanges divide the casing into a number of compartments, each of which is filled with the fibrous material.

IPC: C08J7/052
Filed: 1967-01-27
Abstract: 1,176,204. Coated films. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 Dec., 1967 [27 Jan., 1967], No. 4206/67. Heading B2E. [Also in Division G2] Coated biaxially oriented organic thermoplastic polymeric film is produced by applying a layer of a copolymer of ethylene and another unsaturated monomer copolymerisable therewith to at least one surface of the film which is then stretched to biaxially orient it and subsequently applying the desired coating material to at least one of the coated surfaces. The copolymer may be applied as a melt, dispersion, or as a solution. The copolymer may be of ethylene and vinyl acetate, ethylene and an alkyl acrylate or methacrylate, or ethylene and other olefines e.g. propylene. The film may be of polymers or copolymers of alpha-olefines e.g. ethylene, propylene, butene, 4-methyl pentene 1; linear polyesters e.g. polyethylene terephthalate and polyethylene 1:2 diphenoxy ethane-4:4<SP>1</SP> dicarboxylate; polymers and copolymers of vinyl chloride; and polyhexamethylene and adipamide. The copolymer may be applied to an extruded polypropylene tube which is then expanded by internal gas pressure to stretch and orient it in the transverse direction and withdrawn at a greater rate than it is extruded to stretch and orient it in the longitudinal direction. The film may be sequentially stretched to orient it in two mutually perpendicular directions in its plane and the ethylene copolymer is applied to the film between the two stretching steps. The coating material may be a heat seal coating polymer, examples of which are given. The ethylene copolymer-coated film may be surface oxidized by treatment with chromic acid in sulphuric acid, hot nitric acid, ozone, corona discharge, ionising radiation or flame prior to further coating. A coating material may also contain ferro-magnetic materials, waxes and slip agents. The coated film may form pressure sensitive adhesive films, typewriter ribbons or carbon paper, photographic film, e.g. having a coating of a water permeable colloid such as gelatin containing photo-sensitive materials such as silver or diazo compounds, or if desired a photosensitive layer may be applied above the gelatin layer.

Title: Method and apparatus for photo-electric determination of othe concentration of a suspension of magnetic powder particles which are fluorescently pigmented
IPC: G01N21/47
Filed: 1975-01-31
Abstract: 1458942 Concentration determination for a suspension of magnetic particles INSTITUT DR FORSTER PRUFGERATEBAU 31 Jan 1975 [25 March 1974] 4375/75 Heading G1A A method for this wherein the liquid suspension 2 is made to flow along a surface 11 from which a defined magnetic flux 12 protrudes, and the intensity of fluorescence of the particles accumulating where flux 12 emerges is measured photoelectrically. Apparatus for this includes rotor 1 partly immersed in suspension 2, means for rotating it, a light source illuminating an area of surface 11, from which, as rotor 1 turns, magnetic flux which has passed through the suspension protrudes of a photo-cell to which the area is exposed. Suspension 2 in a container escapes through an overflow to spray nozzles in an inspection area and is pumped back through an inlet pipe. Alternatively the container can be inserted in the suspension circuit or in a by-pass line of it; or inspection can be done in the container. Magnet 6, polarized axially, and magnetically soft shells, 7, 8 form a magnetic circuit with annular gap 9. A shrunk on plastics band 10 has a smooth surface 11 on which a band of magnetic particles accumulate opposite gap 9. Rotor 1 can be driven by flange 16 and shaft 17 in bearing 18 or by the jet from the inlet pipe striking paddles 19 on the inner sides of plates 14 and 15. Paddles 19 also stir. The jet also washes off the band before it regains suspension 2. The photo-cell supplies an evaluation unit feeding a display and giving a voltage at its output which may control the admission of magnetic powder or regulate the sensitivity of a T.V. camera scanning the band. An  alternative means of making the leakage flux is by a ferromagnetic body, painted for smoothness and having an electric current and an incision oblique to the magnetic field formed. The light source beam or the photo-cell output voltage may be chopped. Alternatively a ferromagnetic band  covering surface 11 may have slots or drillings to allow flux protrusion at regular intervals.
