Title: Improvements in or relating to friction coupling devices
IPC: F16D13/52
Filed: 1939-02-24
Abstract: 525,658. Friction clutches. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Feb. 24, 1939, No. 6230. [Class 80 (ii)] [Also in Group XXXIV] In vehicle brake mechanism wherein power for applying the brakes is obtained from the vehicle drive transmission through a friction clutch and in which this clutch comprises two discs or sets of discs adapted to be engaged by axial pressure which urges the discs towards an abutment, the discs bear on the abutment through an intermediate member which is rotationally coupled to the abutment but is capable of tilting with respect thereto so that the axis of the discs can assume a direction independent of that of the abutment. Undesirable vibrations of the discs due to the plane of the abutment not being perpendicular to the axis of its driving shaft are thus presented. The device is shown embodied in the brake mechanism described in Specification 525,415, [Group XXXIV]. The friction clutch comprises discs 14, 10 respectively splined to the end 12 of a shaft 13 driven from the gear box and slidably mounted on rods 15 secured to an abutment member 16 which has a cam surface 27 on which bears a roller 36 on the end of the piston rod 35 of a master cylinder connected to the brakes. The clutch is engaged by the plunger 22 of an hydraulic cylinder 23 which receives pressure fluid from a master cylinder operated by the driver, the plunger acting through an end-cap 21. Between the abutment 16 and the adjacent disc 10 is an intermediate member which is rotationally coupled to the abutment by the rods 15 but which has a spherical surface 41 seated on a corresponding surface on the abutment whereby the axis of the discs is rendered self-adjusting. Instead of providing the spherical surfaces, rubber cushions or springs may be disposed between the members 40, 16 to permit the necessary tilting movement. Specification 477,173, [Group XXXIV], also is referred to. According to the Provisional Specification the invention may be applied to multi-plate clutches and to disc brakes.

Abstract: 1,028,843. Disc brake pads. SOC. ANON. FRANCAISE DU FERODO. Feb. 15, 1963 [Feb. 16, 1962], No. 6315/63. Heading F2E. [Also in Division B5.] A pad for a disc brake comprises a support member 10, for example of metal, provided with a hole 11 for fixing the pad to an actuating, fixing or guiding device, a friction lining 12, and a shielding member 13 integral with or separate from the support and positioned so as to constitute the bottom of the hole. In a method of making the pad, the support 10 is placed in the bottom of a moulding matrix 18, Fig. 3 (not shown), having a boss 22 on which the shielding member 13 is supported. A mass 23, e.g. constituted by compressed asbestos, thermohardening resins and metallic or mineral fillers is placed on the support 10 and is compressed by a press plate 21 until the latter comes into contact with the edge 20. During the compression the mould is heated. Adhesive may be spread on the support to improve fixing of the lining and may also be used to retain the shielding member in position. Alternatively, the shielding member may be held by other means, e.g. magnetic. A number of transverse slots 17 may be formed in the pad. In a number of modifications of shielding member, the latter is provided with one or more projections which engage in the hole 11 or which project beyond the surface of the support and become exposed when the lining is worn down to cause squeaking which acts as a warning to the user. A plug of friction material different from that of the lining, for example of graphite, may be incorporated in the lining and may also form the shielding member. The hole 11 may be formed by upsetting a portion of the support, the said portion forming the shielding member.

Title: Drive arrangements for milking machines
Inventor: GABLER EBERHARDT
IPC: A01K1/12
Filed: 1967-02-10
Abstract: In a conveyer-type milking machine, having rotary platforms on which cows stand while being milked, photo-electric detectors are disposed at an inlet and an outlet of the platform.  If a cow is present for more than a predetermined period in the light-beam of one of the detectors, pulses are transmitted through an amplifier to control apparatus for the motor which drives the platform whereby its speed is reduced.  The speed of the motor is increased automatically when the animals leave the light-beams of the photo-electric apparatus.  A further photo-electric detector reduces the motor-speed when the machine operator moves into a certain working-area.  The speed of the motor is also controlled manually with the aid of an indicator.

Filed: 1967-02-10
Abstract: 1,183,265. Recording and playback. THOMSON-CSF. 10 Feb., 1967 [11 Feb., 1966], No. 6595/67. Heading G5R. [Also in Division G2] Apparatus for recording a plurality of holograms in superposition on a sensitive surface 4 in which the objects I 1 , I 2 , I 3 , I 4  . . . to be recorded are photographic transparencies on a support 18 and may be successive frames of a cine film, comprises a laser 1 giving a reference beam F 2  and an illuminating beam F 3  which passes through a transparency to be recorded and is brought to interfere with the beam F 2  at the surface 4. The support 18 is moved intermittently by mechanism 19 through the field of the beam F 3 , while mechanism 20, driving in synchronism with mechanism 19, intermittently alters the orientation of the surface 4 to provide a different inclination thereof for each object recorded. In one embodiment for reading the holograms stored on the surface (4) (Fig. 4, not shown), the surface is intermittently rotated by mechanism (23) similar to the mechanism 20, and the images so obtained viewed through a collimator. Alternatively, the image is formed on a layer of photosensitive material of a picture analyser tube (24) (Fig. 5, not shown) which is scanned to supply a video signal which can be used in a conventional television receiver. The recording and reproduction of television pictures may also be effected by recording the video signal used for transmission directly as a hologram (Figs. 6, 7, not shown). The signal is applied through a synchronizer separator (28) to an optical modulator (18) while a synchronization signal S controls the orientation mechanism, the orientation being changed with each change in the brightness value of a light spot (I), changes being proportional to those in the video signal. The readout system (Fig. 7) additionally comprises a photosensitive cell (31) receiving the image (I<SP>1</SP>) of the light spot (I) The electric signal from the cell (31) is applied to an amplifier (30) which thus gives the video signal at its output.

Title: Improvements in or relating to fumigating compositions
IPC: A01N25/20
Filed: 1948-03-03
Abstract: A fumigating composition consists of a mixture comprising a thermally vapourizable pesticidal or insect-repellent compound and grains comprising ammonium nitrate and charcoal in which grains the ammonium nitrate is at least partly absorbed by the charcoal and in which mixture the quantity of the pesticide or insecticide is insufficient to render the grains self-combustible. The grains may be obtained by milling a moist mixture of ammonium nitrate and charcoal, and drying the product.  The preferred pesticidal compounds are D.D.T. and hexachlorocyclohexane.  An ignition-aiding reagent such as potassium nitrate or ammonium bichromate may be included in the composition. The temperature of combustion may be lowered by incorporating china clay or common salt in the grains.  The composition may be formed into a cartridge containing an igniting composition and a fuze.  The fumigating charge may be in a compact form or may be lightly compacted into a cartridge having a wrapper of paper or regenerated cellulose.  Specification 584,853 is referred to.

[Also in Division G1] In a circuit for detecting increasing and decreasing current or power and in which an input signal is fed to two parallel R.C. circuits 88, 90 and 92, 94 having different time constants, bistable units 96 and 98 are respectively turned on by increasing and decreasing input signals and operate respective relays. Each bi-stable unit is associated with a biasing winding, Fig. 3d (not shown), which determines the operating point of the unit. When the input signal increases, capacitor 90 charges up more rapidly than capacitor 94 and transistors 108, 110 operate to pass through windings 100, 104 a higher current then flows through windings 102, 106. Under these conditions, depending on the biasing winding, bi-stable 96 is turned on and operates its relay Pi (Fig. 4, not shown). For a decreasing input, capacitor 94 discharges more slowly than 90 and windings 102, 106 pass more current than windings 100, 104. Bi-stable 98 is turned on. Under steady state conditions, if the input is constant, capacitors 90 and 94 are charged to the same voltage and bi-stables 96 and 98 are both in the off condition. A centre zero micro-ammeter 124 detects any unbalance in the circuit.
