Title: Disc brake
IPC: F16D65/092
Filed: 1974-10-17
Abstract: 1482529 Disc brakes; brake pads; reducing brake noise SOC ANON DBA 17 Oct 1974 [8 Nov 1973] 45035/74 Heading F2E A disc brake has pads 14, 16 urged into frictional contact with a disc 12 by brake applying means associated with a torque taking member 10, and each pad (e.g. 14) comprises a backing plate 22 to which a friction lining 24 is fixed, the backing plate 22 having a T-shaped extension 26 each end 28, 30 of which is formed with a bracing edge 32, and a sliding edge 34 which co-operate with corresponding anchoring and carrying surfaces 36, 38 on the torque taking member 10; during frictional contact between the lining 24 and the disc 12 a tangential force T is generated and the arrangement is such that the edges 32, 34 and the surfaces 36, 38 are radially offset relative to force T, the edges 34 and the surfaces 38 being substantially parallel to the line of application of force T and the edges 32 and the surfaces 36 defining an angle d with a plane perpendicular to the line of application.  As shown, the brake applying means for pad 14 is a fluid-pressure-operated actuator 18, and for pad 16, either a second brake actuator or a reaction element of the torque taking member which then slides axially on a fixed support. In the embodiment of Figs. 1-3 the surfaces 36, 38 of torque taking member 10 form grooves 40, 42 in the axial edges of an aperture 20 in the member 10. The pads are braced by one only of their edges 32 for each direction of rotation of disc 12, while the edges 34 prevent the pads moving radially inwardly. A noise reducing metal wire spring 44 passes through a hole 46 and a notch 48 formed in the extension 26, and bears on the surface 36 of groove 42. When the brake applying means are operated with the disc rotating in direction A the force T is transmitted entirely to the member 10 by way of edge 32 as indicated by T1 and a tilting torque is generated which is distributed between the surface 36 of groove 40 and the surface 38 of groove 42 as indicated by F2 and F1 respectively. The resultant force R of forces T1 and F2 exerted on member 10 is determined as a function of the dimensions of the pad, and defines with T1 angle d whose tangent is substantially equal to the distance from the centre of edge 32 to the line of application of force T, in a plane parallel to the plane of the disc, divided by the distance separating the centres of edges 32, 34 when the centres are projected into the plane of the line of application of force T. The edge 32 is made substantially perpendicular to the resultant R. Fig. 4 (not shown) illustrates a pad for use with an annular disc and having a T-shaped extension (126) directed radially inwardly. The extension (126) has two holes (146) and two notches (148) to receive a noise-reducing wire. Like the pad of Fig. 3, the pad of Fig. 4 is substantially symmetrical relative to an axial plane perpendicular to the line of application of the tangential force T and passing through the point of application B of the force T.

If one photo-cell is within the image zone, and the other is outside, indicating an acceptable size of indentation, then the two photo-cell outputs will be of different magnitude and a first signal is produced from the detector circuitry. If both photo-cells are either within or outside the image zone, indicating that the indentation diameter is unacceptable, both outputs will be of the same magnitude and an alarm light and/or reject/working mechanism will be actuated to indicate a faulty metal sample. Each photo-cell may be replaced by a pair of photo-cells in a bridge arrangement, Figs.2 and 4 (not shown). The outer photo-cells (10, 11) of the two pairs are subject to constant illumination, and the state of balance of the two bridges provides the indication as to image size, Figs.6a-c (not shown).

Filed: 1968-09-27
Abstract: 1,240,854. Insulators with finite surface resistance. BRITISH RAILWAYS BOARD. 4 Dec., 1969 [27 Sept., 1968], No. 46038/68. Heading H2C. A synthetic plastics insulator has finite surface resistance provided by a continuous sheet coating forming its outer surface. The value of resistance is chosen to be such that under polluted conditions insulator leakages of 7 milliamperes and less are carried conductively in the surface of the insulator where the pollution is absent or non-conductive, so that surface tracking is inhibited. It is stated that tracking is insignificant for insulator leakage currents greater than 7 milliamperes. The surface resistance may be provided by resin mixed with antimony doped tin oxide. A formula is given relating the minimum current for which tracking is to be permitted to the current in the surface of the unpolluted insulator for a given voltage across it, and from the latter current the required resistance of the surface can be calculated. A correction can be made if the surface resistivity is dependent on the voltage stress in the surface.

Title: Flare light compensator
IPC: H04N5/257
Filed: 1970-09-30
Abstract: 1280933 Television HAZELTINE CORP 30 Sept 1970 [24 Dec 1969] 46481/70 Heading H4F [Also in Division H1] To compensate for the effects of flare light on the output video signal derived by a light detector 8 in a CRT 5 flying spot scanning arrangement, the face plate of the tube 5 is arranged to have a thickness T at least as great as H/4 tan # where H is the shortest dimension of the scanned raster on the face plate and 0 is the critical angle for internal reflection of light for the face plate material. Such a flying spot scanner is said to emit a substantially uniform flare light over the raster area. A pedestal signal having an amplitude representative of this uniform flare light may thus be developed 12 and combined 20 with the video signal to provide a compensated output video signal. The pedestal signal is developed by averaging 13 (e.g. using an RC transistor integrator) the video signal over an image scan period, the resulting signal which has an amplitude proportional to the average amplitude of the video signal being clamped 14 to a fixed reference level during each blanking interval of the raster. The amplitude of this pedestal signal is adjusted in flare cancellation adjuster 15 and since in this arrangement its polarity is opposite that of the video signal it is added to the video signal in combining circuit 20 to provide the compensated output video signal. The minimum thickness T, Fig. 4b, of the face plate 29 for adequate compensation is so determined that light from a phosphor dot 23 excited by the electron beam striking the centre of the raster has its first bounce reflection 30 occurring outside of the raster area in the direction of the shortest dimension of the raster. This is a minimum requirement, and in certain situations it is preferable if the face plate thickness is greater than the target dimension of the raster. The face plate may comprise a continuous body of transparent glass or may be formed by bonding a transparent plastics portion to the exterior surface of a conventional flying spot scanner having a thin glass face plate.

Abstract: 1489091 Time switches COPAL CO Ltd 28 Oct 1974 [29 Oct 1973] 46573/74 Heading H1N [Also in Division G3] A mechanism for an alarm clock comprises a switch 1 which is closed, e.g. to turn on a radio, by means of a lever 9 which turns clockwise on pivot 10 under the force of a spring (not shown) when a driven alarm wheel 8 moves axially toward an alarm set wheel 7 at a preset time, and two slide plates 11, 12 which are coupled together by a tension spring 13 and controlled by a manually settable drum 14, the slide plate 11 having its end 11a between the lever 9 and switch actuator 1a, and the slide plate 12 also being engagable with the lever 9 and having an arm 12b to restrain an alarm vibrator 24 and being coupled to a "drowse" device 21 whereby the plate 12 can be held for a period in the restraining position. The plates 11, 12 are respectively coupled to a cam slot 14a and a peripheral cam 14b on the drum 14 by levers 17 and 19 which pivot about a pin 18. The drum also carries an operating mode indicator 14c and is held in its set positions by a pawl 15. The mechanism is shown in the OFF position in which the levers 17, 19 are rotated clockwise, as seen from above, displacing the sliders 11, 12 to the left so that the switch 1 is open and the vibrator 24 restrained. From this position, the drum 14 may be rotated slightly anti-clockwise to an ON position in which the slider 11 is moved to the right, closing the switch. Alternatively a slight clockwise rotation of the drum selects a RADIO WAKE position in which the slider 11 is free and the lever 9 can pivot under its spring bias to close the switch when the wheel 8 moves to the right at the preset time. A further clockwise rotation of the drum selects an ALARM position in which closure of the switch is followed a few minutes later by release of the buzzer 24. The latter may be silenced for a "drowse" interval by depressing a pivoted plate 20, bringing teeth 21a on the device 21 into mesh with a wheel 25 which is driven by the clock synchronous motor 23. The switch may also be closed for a desired interval by rotation of a "sleep" setting drum 2 so that a cam 2a thereon rotates a lever 4 to depress actuator la. The "sleep" time is determined by the meshing of a partial gear 2b on the drum with a gear 3 driven by the clock, and the switch opens when the gears come out of mesh.
