Title: Improvements in or relating to reversing gearing and controlling means therefor
IPC: F16H3/00
Filed: 1939-02-13
Abstract: 527,907. Reversing rearing ; brakes. WESKENSON CORPORATION. Feb. 13, 1939, No. 4663. Convention date, Feb. 19, 1938. [Classes 80 (i) and 80 (ii)] [Also in Group XXXIV] Reversing gearing, particularly for the propellor shafts of boats comprises a driving shaft 24, which is driven by a shaft 14 through a reduction gear 21, 22, a driven shaft 15 and a countershaft 37. The driving shaft is adapted to be clutched direct to the driven shaft 15 for forward drive by means of a sliding gear member 32, 33, the teeth 32 of which engage with similar clutch teeth 34 on a gear 26 secured to the shaft 15. For a reverse drive the gear member 32, 33 is moved to the right so that gear 33 is moved into mesh with an idler gear 35 which drives the countershaft 37 by a fixed gear 42 theron. At the same time, by means of a double operating lever 65, a sliding gear 43 on the countershaft is moved into mesh with the gear 26 on the driven shaft. During the change from forward to reverse or vice versa a roller 74 at the end of lever 65 operates on a cam 76 on a bell-crank lever 75, 55 to move a braking member 44 against the gear 26 so that the rotation of the driven shaft is stopped prior to the engagement of the gears or clutches for rotation in the reverse direction, thus facilitating the change. The brake member 44 is carried in a cylindrical drum 46 and has arms 63 carrying rollers 62 bearing on spring supported plungers 61. During reversing the momentary depression and release of the plungers 61 assists in giving a rebound torque to the driven shaft. The teeth of the gears may also be suitably shaped to assist in their meshing, such as by tapering the ends thereof and by making one of the teeth longer than the remainder. The engagement of the direct drive forward clutch may be further assisted by an auxiliary clutching device shown in Fig. 13 in which auxiliary clutching surfaces 95, 96 first come into engagement, these surfaces being formed by a few strong shallow teeth, to synchronize the speeds of the two parts and then the clutch member 132 moves against a spring resistance 103 to engage the teeth 134 on the driven gear 126.

Title: Improvements in or relating to illuminated signs or representations for advertising and other purposes
IPC: G09F13/26
Filed: 1931-02-14
Abstract: 373,140. Luminous signs. WARD, C. W., 9, Calabria Road, Highbury, London. Feb. 14, 1931, No. 4780. [Class 3 (ii).] A sign comprises an opaque member 84 having translucent portions 82 in the form of characters through which light is transmitted, and a sheet of glass 81 which is arranged in front of the opaque member and adapted to reflect light back on to it to produce the effect of diffused light round the bright characters such as is obtained with a neon sign. A part 83 forming a border for the characters may be provided, and this may either be more reflective than the part 84, to simulate the effect produced by the walls of the tube in a neon sign, or else black, in which case a dark border appears round the letters. The preferred method of construction is to coat.the glass with foil which is then removed except at the pa.rts 82, 83, after which a layer of paint 84 is applied ; the foil is next removed from the parts 83, and a layer of paint 85 is added ; finally all the foil is removed and a final layer of coloured translucent paint 86 is applied over the whole surface. In a modification, only the members 81, 84 are employed, the latter being of a material which is translucent in thin layers but substantially opaque in thick layers and being tapered off towards the part 82, so that an effect of gradually decreasing illumination is obtained around the bright characters. Further effects may be obtained by shaping the front surface of the glass and causing the lamps which illuminate the device to flicker.

Title: Improvements relating to bogies for rail vehicles
Inventor: LYON STANLEY CLARKE
IPC: B61F3/08
Filed: 1953-02-20
Abstract: 745,536. Underframe details of railway vehicles. ENGLISH ELECTRIC CO., Ltd. Feb. 19, 1954 [Feb. 20, 1953], No. 4793/53. Class 103 (6). In a railway vehicle bogie 3 of the kind in which the vehicle superstructure 1 is supported by a spring bolster 4 capable of transverse movement with respect to the bogie but constrained to rotate with the bogie, and including a tractive effort beam 2 which passes below, as shown, or through the sides of the bogie, the beam 2 is connected to the bogie through a pivot pin 7 arranged to transmit traction and braking stresses and to allow relative transverse movement of the beam and the bogie, such transverse movement being restrained by arcuate guide faces 16 located at or near the outer ends of the bolster 4 which co-operate with arcuate guide faces 15 associated with the superstructure 1, so as to form sectors of a bearing allowing relative pivotal movement of the bolster and the superstructure, the radial clearance between the co-operating guide faces being sufficient to ensure that tractive and braking stresses are not transmitted to the bolster. As shown, the pivot pin 7 is journalled in a spherical bearing 10 which is mounted in a slot 9 in the beam 2 so as to be capable of transverse sliding movement. The pin is free to move vertically relatively to the bearing 10. The weight of the superstructure 1 is transmitted to the bolster 4 through side bearers 11 located in recesses in the beam, and sliding plates 12 which rest on the bolster. The plates 12 have spherical recesses to receive the bearers. The bolster engages transversely-retarding slots 13 in brackets 14 bolted to the bogie whereby relative rotary movement between the bolster and bogie are prevented. The bolster is suspended from the bogie by leaf springs 5 and swing links 6 which allow limited transverse movement of the bolster relatively to the bogie. In a modification the bolster is constrained to rotate with the bogie by means of interconnecting links which allow relative vertical movement of the bolster and bogie.

Title: An improved supervising arrangement for unattended amplifiers
IPC: H04B1/74
Filed: 1953-02-20
Abstract: 720,733. Unattended repeaters. FELTEN & GUILLEAUME CARLSWERK AKT.-GES. Feb. 20, 1953 [May 21, 1952], No. 4828/53. Class 40 (4). Failure of a valve heater in an unattended repeater causes a transistor oscillator to send a fault signal frequency to supervisory positions, the identity of the faulty repeater being determined either by the signal frequency or the signal level. Each repeater comprises an amplifier 3 having valve heaters 5 energized by a constant direct current supply, the signalling and direct currents being segregated by condensers 2 and chokes 4. If a heater becomes open-circuited, the constant direct current causes the potential across a shunt resistor 6 to increase and start a transistor oscillator 7. The generated fault signal frequency is then applied to the line over a condenser 8 and operates a supervisory alarm arrangement 9. A second oscillator may be used for transmitting fault signals in the other direction. In the case of a four-wire system with supervision at one end only, line loops are provided for transmitting fault signals to the supervised end.

Abstract: 737,414. Photographic cameras. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 25, 1953 [Feb. 28, 1952], No. 5266/53. Class 98 (1). A camera for photographing an image on a fluorescent screen in which a spherical concave mirror forms an image on a photographic film strip held over a convex spherical pressure table by a frame clamping the edges of the picture area, is characterized in that clamping means are provided by which the film is clamped at its edges against the frame before the film is deformed by bringing the pressure table and the frame together. As shown in Fig. 1, a film strip 8 passes through the side of a housing 1 of a camera in which the image is formed by means of a concave spherical mirror 2, and passes out on the same side after passing over a pressure table 14. The pressure table is mounted by means of a ball-and-socket joint to an arm 13 pivoted at 12 and carrying also guide rollers 9, 10, 11. When arm 13 is rocked forward, the pressure table 14 forces the film against a frame 3 with edges 16 curved to conform to the pressure table 14. As shown in Fig. 2, a frame 25 mounted by springs 26 on the pressure table carries metal strips 24 at each side of the picture area, so that the edges of the strips clamp the film 8 against the edges 16 of frame 3 before the pressure table forces the film into the gate. Alternatively, a piece of springy metal may be fixed to the pressure table, the metal piece having turned-over edges which engage the film at the sides of the picture gate, and move apart slightly when the pressure table moves into position.

Abstract: 306,540. Zeiss, C., [Firm of]. Feb. 24, 1928, [Convention dale]. Eye-examining apparatus. - In apparatus for examining or photographing the retina of the eye by means of a lens through which the Jight for illumination is also passed, the reflection images produced by the various refracting surfaces of the lens are prevented from Teaching the eye of the observer or the photographic plate by an arrangement of diaphragms in conjunction with appropriate curvatures of the lens surfaces and thicknesses of the lens elements. The source of light consists of a diaphragm a<1> on the blackened surface a<2> of the prism a and the light is projected into the eye c by the lens b, which produces a real image of the retina at the position B. The three refracting surfaces b<1>, b<2>, b<3> of the lens are chosen so that the read reflection image e<1> of the source of light a' from the surface b is on the surface b<2>, the surface b<2> produces a virtual image e<2> and the surface b<3> produces a Teal reflection image in the plane, e<3>-e<3> below the axis. The image e<1> is dealt with by the stop f<1> on the surface b<2> and the image e<2> by the stop f<2> on the same surface, the stops being very small. In order to provide a spherical correction of the lens and for the fulfilment of the sine condition the surface b<1 >is deformed. Numerical data are given in the Specification.

Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08J5/02
Filed: 1931-02-20
Abstract: Sheeting comprising integral portions of different nature is made by the consolidation by filtering of two types of granular dispersions of rubber or the like, one containing fibrous material, the other being substantially free therefrom.  The granular dispersions are obtained by effecting the coagulation of aqueous dispersions by precipitation in situ of compounding ingredients formed by the double decomposition of water soluble reagents having normally no coagulating effect with subsequently added water soluble reagents an ion of which may incidentally possess coagulating influence. Examples of suitable reagents are given.  The fibrous material may be added before or after coagulation, and may comprise leather fibre, asbestos fibre, wood pulp, wood flour, jute fibre, cotton flock or paper pulp. Sheeting may be produced in which there is a gradual change in composition from one side to the other, successive layers of the granular precipitate each containing a lower proportion of fibre being poured into the filtering device, and the whole being consolidated by filtration aided by suction and pressure. Examples are given of the formation of a sheet consisting mainly of leather fibre with a facing of rubber and of a sheet in areas of leather fibre are surrounded by areas of rubber. Specifications 219,365 and 290,313, [both in Class 70, Indiarubber &c.], are referred to.

Abstract: 839,683. Thermionic valves. STANDARD -TELEPHONES & CABLES Ltd. Feb. 17, 1959, No. 5429/59. Class 39(1). A tubular anode for thermionic valves e.g. rectifiers has longitudinal heat radiating fins projecting radially outwards in or closely parallel to a diametral plane, the fins each having an end portion bent normal to the plane and directed in the same clockwise or anticlockwise sense. The anode is formed from two similar sheet metal halves of semi-tubular form each having a pair of fins 67 projecting therefrom, the sheet metal being bright on the inward facing surface and black on the other surface. One fin 7 of each half has its end portion with the black side 8 facing outwards and overlaps the adjacent fin 6 on the other half. The adjacent fins may be welded together, Fig. 2, or spaced apart by members 10, Fig. 3, which do not extend the complete length of the anode so that gaps are left through which cathode gas, evolved during processing of the valve, may escape. The spacing members 10 are preferably of zirconium or titanium, which metals act as getters when hot. The tubular anode may be of circular or rectangular crosssection; and may be of carbonised nickel, polished on one side and blackened on the other, or of laminae of different metals, e.g. iron clad with nickel on one side and aluminium on the other.
