Title: Improvements in lamps for light signals, or indicators
IPC: B61L5/18
Filed: 1922-10-28
Abstract: 209,868. Szlumper, A. W., and Thorrowgood, W. J. Oct. 28, 1922. Signal lamps.-A signal lamp for use on railways &c. is constructed to emit two or more separate beams of light from a single lens. As shown in Fig. 1, the lamp may comprise three sources of light such as electric lamp bulbs 1, 2, 3 disposed one at the focus of the lens 7 and one on each side thereof, each at the same distance from the centre of the lens as the first one and adapted to throw beams of light across the track 8 as shown, thereby giving a desired indication to the driver of a train &c. as he passes through the beams. A reflector may be placed behind each lamp bulb for concentrating the beams. In a modification, Fig. 3, a single source of light 19 is employed in conjunction with reflectors 13, 14 arranged so as to produce three beams of light as shown. Where it is impossible to place a lamp a sufficient distance from the track to produce the desired effect, the lamp is arranged to project its beams on to one or more screens or reflectors disposed alongside the track and adapted to reflect the several beams of light back across the track. Coloured lenses or coloured sheets of glass placed behind the lenses are employed when colour signals are required.

Title: Improvements in and relating to electric switching means for preventing unauthorisedstarting of motor vehicles
IPC: B60R25/04
Filed: 1919-11-26
Abstract: 150,573. Monkhouse, P. E., and Roberts, G. Nov. 26, 1919. No Patent granted (Sealing fee not paid). Guarding against unauthorised use.-Relates to means for locking the bonnet or inspection flap of the bonnet of a, motor-vehicle and at the same time short-circuiting the ignition magneto located within the bonnet. The side of the bonnet or the inspection flap is provided with a plate on which a rotary key-operated barrel is mounted in lost-motion engagement with a double-ended arm 10 rotatably mounted on the barrel. The arm 10, when rotated, presses outwardly the upper ends of lever arms 15, 16 against the action of springs 19. When the barrel is rotated by the key from the position shown, the upper ends of the lever arms are released, and under the action of the springs the locking ends of the arms engage beneath lugs 27 of a bracket fixed on the frame of the vehicle, and at the same time engage with an insulated spring contact 34 connected to the magneto, thereby earthing the magneto. When the barrel is unlocked. the magneto is again operated.

Abstract: 988,412. Reactor pressure vessels. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Aug. 16,1961 [Aug. 26, 1960], No. 29561/61. Drawings to Specification. Heading G6C. A liquid-cooled and moderated nuclear reactor installation has a surrounding zone to reduce the effect of rupture of the pressure vessel. The pressure vessel is mounted within a containing chamber and the zone between the inner walls of the chamber and the outer walls of the pressure vessel encloses water-filled tanks and a layer of foam plastics. The tanks, if fractured by a pressure vessel explosion, release water which condenses the steam escaping from the reactor. The foam plastic absorbs the explosion impulse. A neutron absorbing substance may be added to the liquid filling of the tanks to form a biological shield.

Title: Printer ribbon drive arrangement
IPC: B41J33/38
Filed: 1975-07-15
Abstract: 1504770 Ink ribbon feed SIEMENS AG 15 July 1975 [30 Aug 1974] 29578/75 Heading B6F During movement of a type carrier carriage 1 in the direction of the arrowheads during printing a printer ribbon 2 is unwound from one spool and wound on to another spool. Each spool 3, or 4 is rotatable upon rotation of a respective roller 8 or 9. Rollers 8 and 9 are looped with respective cables 10 and 11 one end of each of which cables is secured to aspring biased armature 13 or 14 of electromagnets 15 or 16 respectively. To wind the ribbon 2 onto the spool 3 electromagnet 16 is energized to slacken the cable 11, while the electromagnet 15 is de-energized to tighten the cable 10 about the roller 8. Upon movement of the carriage 1 roller 8 is rotated to wind the ribbon 2 on to the spool 3. When the spool 3 is full a sensing lever 19 senses increased tension on the ribbon 2 to actuate a contact 20 whereby the electromagnet 16 is de-energized while the electromagnet 15 is energized to slacken the cable 10. The ribbon 2 can now be unwound from the spool 3 and wound on the spool 4. during carriage movement, When the carriage is returned to the line-commence position both the cables 10, 11 are slackened to prevent rotation of either spool. Only one drive roller having a cable looped therearound may be used. The roller moves along the cable during carriage movement, and rotated when the cable is tightly embraced therearound and not rotated when the cable is loosely wound therearound. The diameter of the drive rollers is three times the core diameter of the ribbon spool. A steel cable and a drive roller having a steel tread may be used. In another embodiment, Fig. 2 (not shown), the two cables 10, 11 are oppositely tightened and relaxed by means of a common two-armed hinged armature (21) of an electromagnet (22) and a spring (23). The magnet is de-energized during carriage return movement during which the spring force is counteracted to slacken the tensioned cable substantially so that no drive is transmitted. Also the drive rollers 8, 9 are connected to shafts 6, 7 via idling members 25 and 26 respectively to prevent ribbon translation. Only one idling means for the drive roller may be provided.

Title: Trueing mechanism for form grinders
IPC: B24B53/08
Filed: 1953-10-27
Abstract: 727,786. Trueing grinding-wheels. GEAR GRINDING MACHINE CO. Oct. 27, 1953 [Jan. 16, 1953], No. 29679/53. Class 60. A trueing mechanism for rotary form grinders comprises a cutter D, Fig. 6, having an arcuate cutting edge E of small radius and means operating during the trueing movement to oscillate the cutter continuously through a limited angle about the centre of the arc. In the preferred embodiment, the cutter is mounted on a pantograph with the centre of the arc in alignment with one of the pivotal connections B<SP>1</SP>, Fig. 5, and is oscillated by a drive comprising concentric pairs of pulleys N<SP>2</SP>, N<SP>4</SP> and N<SP>7</SP>, which are mounted at the pivotal connections B, B<SP>2</SP> and B<SP>1</SP> and connected together and to a gear-wheel I, Fig. 1, by belt drives. A motor M causes the gear-wheel I and hence the cutter E to oscillate through an adjustable crank M<SP>1</SP>, a link M<SP>3</SP> and an internal gear-wheel J connected to the gear-wheel I by a pinion K on a fixed arm L. In addition to the oscillating movement, the cutter E receives an automatic angular adjustment when a follower F moves from one side P<SP>1</SP> of a template to the other side P<SP>2</SP>. This is accomplished by a switch T which is held open by a pad T<SP>2</SP> on the link A<SP>3</SP> while the follower is in contact with the side P<SP>1</SP> and allowed to close when the follower is moved to side P<SP>2</SP>. The switch energizes a solenoid-operated valve to admit fluid to a hydraulic cylinder and rock the arm L which thus displaces the gear wheel I and hence the cutter. If desired, the valve may be operated manually. The ends of the link A<SP>1</SP> of the pantograph are bifurcated to receive the links A<SP>2</SP> and A4.

Title: Improvements in and relating to methods of impregnating oil- and water-proof fabrics
IPC: D06M15/233
Filed: 1933-10-27
Abstract: Fabrics, for example of cotton, silk or artificial silk are rendered transparent, oil-proof, waterproof, and electrically insulating by impregnation with polymerized styrol, which may contain a softening agent.  The fabric may be impregnated with monomeric styrol, to which catalysts may be added, and polymerization effected on the fibre, for example by exposure to a mercury lamp.  Fillers such as jute fibres or cork powder may be added.  If diphenyl chloride is added, the fabric is rendered fireproof.  Preferably polymerization is effected so that the refractive index of the polymer is the same as that of the fabric, for example by adding hydroquinone when the desired index is obtained.  The product may be used as packing material or as a substitute for oiled silk, linoleum, and splinterless glass.
