Title: External rear view mirror assembly for a vehicle
IPC: B60R1/076
Filed: 1972-09-15
Abstract: 1402902 Rear-view mirrors Y J TALBOT 15 Sept 1972 42916/72 Heading B7J An external rear view mirror assembly comprises a mounting 3 adapted to be secured to the body 1 of a motor vehicle, a cranked arm 6 having one end portion supported by the mounting 3 to be rotatable about the axis D-D 1  of a hinge pin 5 and a mirror housing 8 articulatedly connected such as by a ball pin 7 to the other end of the arm 6 which has receiving means formed by the bore of an eye 13 for the pin 7, the axis of symmetry V-V 1  of the bore and pin intersecting the axis D-D 1  at a point. The portions of the axes D-D 1  and V-V 1  extending from this point towards the arm 6 include an acute angle α. The point of intersection and the housing 8 are on opposite sides of a plane which is perpendicular to axis D-D 1  and which extends through the mounting 3. The arm 6 is retained in its normal operative position, as shown in Fig. 1, by a detent arrangement comprising balls 9 and springs 10 urging the balls into recesses in the surface of mounting 3, but on receipt of an impact, the housing 8 and arm 6 are pivoted to positions 8<SP>1</SP> and 6<SP>1</SP> within the profile of the body 1. In order to reduce air resistance, an aerodynamically shaped housing 8 as in Fig. 6 may be employed, comprising at least two, three as shown, housing parts 8a, 8b and 8c each of roughly the cross-section of a sector of a circle. These housing parts may be telescoped together by pivoting about a common axis M against the resilient resistance of an elastic foam material filler 36 as shown, or of a compression spring. A flexible tension element 33, interconnecting a rubber buffer mount 34 on part 8c and a screw 32 adjacent the reflector glass 37 in part 8a, limits outward telescoping movement of the housing parts. Alternative forms are described including the use of a twopart coupling arm 6 having its parts (6a and 6b), Fig. 5 (not shown), connected by a hinge pin (39) perpendicular to axis D-D 1 ; and a convex mounting 3 engaged pivotally adjustably in a concave channel (16), Fig. 3 (not shown), of the vehicle body to allow variation of the angle α and preferably dipose the axis of ball joint pin 7 vertical. When mounted on the vehicle with axis V-V 1  vertical, the axis D-D 1  is inclined upwardly to extend towards the central vertical longitudinal plane of the vehicle.

A tedder comprises a rotating drum consisting of tine supporting bars mounted on members 31, 32 secured to a U-shaped frame 1, 2, 3, 4 supported on ground wheels 8, 9. The drum is driven from a transmission shaft via a splined shaft 24 driving a pulley 25 and belt 40. The draw-bar 26 is connected to the frame of the machine through a vertical pivot. Rings 43 and 50 on the drum and plates 44 and 49 on the frame protect the moving parts of the drum. The tine-supporting bars are characterized by stops which limit the forward deflection of the tines whereby the crop is shaken off from the tines. In Fig. 4 the tine bar is hollow and has on its tine supporting side three inclined faces 52, 53, 54 the forward deflection of the tine 60 being limited by the faces 52, 53. In Fig. 8 the tine bar 66 is of angle section having an offset portion forming a stop for the tine 72. The offset portion may be replaced by a rubber buffer. The tines are arranged in pairs, each tine having an associated spring 61 and the pair being fixed to the tine bar at a single fixing point 64. In an embodiment (Fig. 10) the tine bars 90 are round and are secured in arms 87, 88 so that they can be turned relative to these arms. The tine bars 90 can be removed from the arms 87, 88, and, by loosening bolts 96 which slide in slots 95, the arm 88 can be moved relative to the arm 87 so that the machine occupies a reduced volume of space. In this embodiment the tines are arranged on the bars so that the bars form a stop to limit deflection of the tines. Specification 1,006,712 is referred to.

Title: Composite structures of heat-recoverable articles
IPC: H01H85/165
Filed: 1974-10-08
Abstract: 1530994 Heat recoverable insulators RAYCHEM Ltd 7 Oct 1975 [8 Oct 1974] 43536/74 Heading H2C [Also in Division B5] A heat recoverable article, e.g. an insulator, for use in covering a substrate, comprises an elongate hollow member having at least one hollow end and a plurality of outwardly extending sheds 3 each of which extends round at least part of the periphery of the article. The article is formed of a heat-recoverable material such that, both before recovery and on partial recovery of the article around and into contact with the substrate, each shed will be inclined to the longitudinal axis of the article whilst on complete recovery of the article, the sheds are substantially perpendicular to said axis. As described, the sheds may each extend continuously around the periphery. Alternatively each may extend over a part of the periphery in which case the article may be of the wrap around form, i.e. a longitudinal seam is formed after moulding. The outwardly extending portions are preferably integrally formed with the remainder, and one or more may extend helically around the article. In a modification all the portions may be provided by a single helical member. As described, each article is preferably moulded in a heat-stable state with the outwardly extending portions substantially perpendicular to the longitudinal axis thereby allowing ready removal from the mould. The internal dimensions of the article are then expanded, e.g. by a mandrel, to a first heatrecoverable state, and slipped over the substrate, e.g. bush or insulating post. The article is then heated so as to partially recover around the substrate. The composite structure, i.e. article plus substrate, may be used as a high voltage insulator, the outer surface then being of a non- tracking material. The substrate may be a fibre reinforced electrically insulating material. The article alone may provide insulation in which case the substrate may be an electrical component, e.g. a cable. An adhesive may be used to bond the article to the substrate and at least part of the article surface in contact with the substrate may be provided with a stress-grading layer. An extensive list of possible adhesives is given. Dimensions are given.

Abstract: 1,017,197. Solvent recovery apparatus. M. ZIMMERMANN. Oct. 26, 1964 [Oct. 25, 1963], No. 43546/64. Heading B1L. A solvent recovery apparatus comprises a chamber 2 containing activated charcoal and an evaporation vessel 7 open at the top and directly connected into the bottom of said chamber. As shown in the Figure, to which the above numerals refer, air saturated with solvents, e.g. perchloroethylene and trichloroethylene, is passed into the adsorption chamber through conduit 1, passes through the adsorbent supported on grid 19 and purified air is removed at 4. After the adsorbent is saturated, valves 5 are closed, valve 26 is opened to fill the evaporator with water, valve 28 is opened and heater 9 is switched on (switch 29). A further heater 11 superheats the steam, avoiding the necessity to generate under high pressure. The solvent is stripped by the steam and the mixture passed to condenser 22 and separator 23. Valves 5, 26 and 28 and switch 29 may be operated by a single handle. Immediately after stripping, vessel 7 is preferably drained and refilled with cold water. An annular cup 17 and drip plate 18 prevent solvent drops and charcoal particles entering vessel 7.

Abstract: 1321297 Photographic shutter control AGFA - GEVAERT A G 11 Sept 1970 [13 Sept 1969] 43546/70 Heading G2A The opening and subsequent closing of a camera shutter is controlled by use of a single electromagnet 17 having a permanent magnet core 18, the control arrangement being such that upon operation of a camera release 26 the current through the coil 19 is such as to produce a magnetic field which augments the field due to the permanent-magnet core, and after a time determined by a timing circuit consisting of a photo-resistor 32 and a capacitor 31 a current is supplied to the coil to produce a magnetic field which opposes that of the permanent magnet core. The magnetic field operates a lever 11 to pivot about a point 10, the lever having arms 9, 13 which engage extensions 8, 16 of shutter opening and closing rings 1, 2 respectively. Lever 11 is initially in the solid line position, pivots to the dash-dot line position to open the shutter, and returns to the solid line position to close the shutter, Whilst the shutter is open, the lever closes contacts 34 to maintain energization of the control arrangements by source 25 irrespective of return of release 26 to its initial position. Alternatively, Fig. 2, (not shown), a charge storage capacitor may be used. Changeover switches 20, 21 and 23, 24 are operated by the initial energization of the electromagnet.

Abstract: 1306670 Frequency generators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 Sept 1971 [24 Sept 1970] 43968/71 A broad-band frequency generator comprises a variable voltage D.C. source 4 connected to a voltage controlled oscillator 1 for varying the stabilized output frequency over a large range, a frequency discriminator comprising a crystal oscillator 5 and a digital counter 6 adapted to continuously count the output pulses from one of said oscillators 5, 1, during consecutive counting cycles whose duration is determined by a gating signal derived from the output of the other oscillator, a digital to analog converter 7 connected to said counter for producing an output corresponding to the deviation of the frequency to be stabilized relative to the discriminator centre frequency characterized by a given counter content, a subtractor 8 for comparing the outputs of the converter 7 and the variable source for applying a correction signal to the controlled oscillator 1 via an integrator 9. At the end of each counting cycle, a time corrector 13 resets the counter 6 to its maximum count position, the difference in the residual values resulting at the end of a cycle corresponding to the desired, instantaneous output frequency respectively of oscillator 1 being a measure of the frequency deviation. Unwanted frequency deviations of oscillator 1 due to temperature variations are eliminated by the correction voltage produced by subtractor 8 and the integrator 9. The output of source 4 may be constituted by the phase compared output of oscillator 1 with respect to a reference source in a further phase controlled loop (not shown). Alternatively source 4 may be a manually adjustable D.C. source. An alternating voltage may be superimposed on the D.C. voltage, the amplitude modulation resulting being converted into corresponding frequency modulation. Decade control switches 26 are provided for controlling a divider 14 when the generator is used as a frequency synthesizer. Figs. 4, 5 and 7 (not shown) relate to embodiments involving alternate arrangements for the counter 6.

Abstract: 1276657 Fluid-pressure servomotor systems DOWTY TECHNICAL DEVELOPMENTS Ltd 10 Sept 1969 [21 Sept 1968] 44989/68 Heading G3P A variable displacement pump or motor includes a displacement varying member 59, means responsive to the operative hydraulic pressure in the pump in motor to exert a restoring force on the member 59 urging it to one displacement limit, a hydraulic servo-cylinder 3, a servopiston 55 mechanically connected to the member 59, a control unit 61 mounted in the servo-cylinder or an axial extension thereof to define a working space 83 between it and the servo-piston in which liquid urges the latter and the member 59 in opposition to the restoring force, and a highpressure port 75 in the servo-cylinder fed with the operative pressure of the pump or motor and connecting directly to the control unit which operates to generate a control pressure in the space 83. When the hydraulic pressure in the output line 6 from the pump increases, a piston 69 is urged to the left against the force of a spring 86 to increase the opening of ports 85 in a valve-member 82 cooperating with the piston 55. An increased flow of liquid into the space at the low pressure side of the pump thus takes place through a restriction 84 to lower the pressure in the space 82 and allow the member 59 to be moved by the restoring force to reduce the delivery of the pump. The restoring force may be produced by the loading of a spring 49 and by the hydraulic pressure in the pump cylinders, the member 59 having a pivotal axis 31 offset from the pump centre-line A-A, or by a separate hydraulic piston and cylinder device. The cylinder block 15 has a splined aperture 51 to receive a drive-shaft and co-operates with a flat valve surface 4. A spring shorter than the spring 86 and enclosed within the piston 55 may be used and the piston 69 may be replaced by a piston actuated by the pressure drop across a restrictor fed from the output line 6.
