Title: Improvements in or relating to electric discharge lamps
Inventor: RIGDEN SYDNEY ALFRED RICHARD
IPC: H01J61/36
Filed: 1965-10-25
Abstract: 1,130,204. Metal-vapour lamps. GENERAL ELECTRIC CO. Ltd. 14 Oct., 1966 [25 Oct., 1965], No. 45091/65. Heading HID. The exhaust stem 15 of a discharge lamp having an envelope 1 of a material containing more than 85% by weight of alumina is made of one of the metals Ti, Zr, V, Ta, Nb or of a ductile alloy of two or more of these metals, and is sealed to an apertured closure member 3 of Nb or to an intermediate member 13 of a refractory metal e.g. W or Mo, or an alloy which forms a matching seal with Nb and with the metal of the exhaust stem, by a layer of one or more of the metals Zr, V, Ti alloyed with the metal or alloy of the exhaust stem. In the sodium vapour lamp shown the stem 15 is made of Ti, and the seal is effected by melting washers 18 and 19 of Zr and V respectively. The lamp is otherwise as described in Specification 1,065,023. In an alternative embodiment (Fig. 2, not shown), a shoulder of the exhaust stem is sealed directly to member 3, and a portion of the exhaust stem projects into the interior of the envelope and is pinched and brazed to the rod 10 using strips (28 and 29) of Zr and V leaving intermediate evacuation ducts. The lamp is filled with sodium and a rare gas, e.g. A. at a pressure of about 20 mm. Hg, and is provided with a cylindrical glass outer envelope (not shown).

Title: Improvements in or relating to devices for conveying rod-shaped objects between two levels
IPC: A24C5/35
Filed: 1967-10-04
Abstract: 1,207,182. Endless conveyers for cigarettes. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 4 Oct., 1967 [5 Oct., 1966], No. 45165/67. Heading B8A. Cigarettes are elevated by being conveyed between opposed conveyer belts 17, 18 to the surface of each of which (through orifices-not shown) suction is applied from chambers 19, 20. A flap 22 responsive to the quantity of cigarettes being fed by an upstream conveyer belt 15, may control the spaed of the belts 17, 18, and the degree of suction. Alternatively, the system may be self-regulating since a lower input to the belts 17, 18 causes a greater number of the vacuum applying orifices in the belts to remain uncovered. This causes an escape of vacuum and a consequent diminished conveying action. In a modification (Fig. 1, not shown) there is no lower horizontal leg of the conveyer 17. Instead, the conveyer belt 15 extends beneath the lower horizontal leg of the conveyer 18. In a further modification (Fig. 3, not shown), the belt 15 is at a higher level, and feeds the belts 17, 18, via a shoot (14).

Title: Coin acceptance mechanisms
Filed: 1974-12-10
Abstract: 1486770 Coin acceptance mechanisms POST OFFICE 10 Dec 1974 [1 Oct 1973] 45859/73 Heading G4V A coin acceptance mechanism has means for checking a coins geometrical dimensions and means for determining its physical properties. The mechanism has a sidewall 2, a sidewall 3 and a guide rail 14. Sidewall 2 is inclined rearwardly and has an aperture 10 in which there is a deflector plate 11 which is inclined rearwardly at a greater angle than sidewall 2. Thus undersize coins fall through the aperture. Correctly sized coins engage the lower edge of guide plate 7. Oversize coins are held by stop 13 or are deflected by curved strip 9 on guide plate 6. The guide plates 6 and 7 are vertically adjustable. A permanent magnet 12 deflects a ferromagnetic coin. An electric sensor or detector 18 is positioned at the lower end of coin shoot 1, and controls the operation of relay 4 to move deflector member 5 out of the coin path when an acceptable coin is detected by sensor 18.

Title: Personal weighing machine having parts of thermoplastic material
IPC: G01G19/44

Patent GB-1145698-A (GB)
Title: Improvements in sludge centrifuges
IPC: B04B1/14
Filed: 1966-10-14
Abstract: 1,145,698. Centrifugal separators. ALFALAVAL AB. 14 Oct., 1966 [18 Oct., 1965], No.46140/66. Heading B2P. A sludge centrifuge in which sludge discharge takes place in operation is provided with a sludge-displacing body 31 which is so shaped and located within the separating space 14 of the centrifuge rotor 1 that the sludge displacing volume of the body is asymmetrically disposed with the respect to the axis of rotation of the rotor. When the sludge 16 attains a predetermined level, it is displaced laterally by the body 31 thereby altering the condition of balance of the centrifuge rotor. This change of the condition of balance, when it is has reached a predetermined value, indicates the time for discharging the sludge from the rotor or for controlling recirculation of the sludge and sludge concentration in the rotor. The rotor 1 is driven by a shaft 4 journalled at its lower end in a bearing 5. A further shaft bearing has its sleeve 6 supported horizontally by springs 7 located in the centrifuge frame 8. An electric device 9 for sensing oscillations is movable in a hole 10 in the frame 8. Sludgecontaining liquid is fed through a pipe 12 and a distributor 13 into the separating space 14 in which a set of discs 15 is inserted. Clear liquid passes through a hole 17 'into a chamber 18 from which it is discharged by means of a paring disc 19. Sludge outlet openings 21 in the rotor are opened and closed by a piston-valve 22, the axial movement of which is controlled by liquid fed into a space 27 by means of a pipe 23. A ring valve 28 is biased upwardly by springs to keep holes 30 normally closed by means of pads 29. The body 31 which is fixedly located in the space 14 is in the form of a ring having a tubular part 31a, Fig. 3, provided with small holes 32 and a solid part 31b. In operation, the rotor and its contents are dynamically balanced. As the separated liquid fills the space 14 it enters the hollow space of the part 31a through the holes 32 so that an unchanged condition of balance is maintained. When the sludge layer grows radially inwardly, mare sludge is displaced by the part 31a than by the part 31b, sludge being unable to enter the small holes 32, so that the centre of gravity of the rotor and its contents is displaced to the right in the situation shown in Fig. 1. This displacement causes a change in the strength of oscillations of the shaft 4 which is sensed by the device 9. The latter generates an alternating voltage which in turn generates an impulse in a device (not shown) connected by wiring 11 to the device 9. When the change has reached the value corresponding to the sludge level at which sludge discharge is to take place, the impulse is sufficiently strong to cause the valve 28 to be pressed downwardly, e.g. by hydraulic means, so that the holes 30 are uncovered. The liquid in the space 27 then flows out through the holes 30 and the piston valve 22 is pressed downwards by the pressure of the sludge and liquid in the separating .space 14 and the openings 21 are uncovered to discharge the sludge.

Abstract: 1,041,379. Laminates. DOMTAR Ltd. Nov. 22, 1963 [Nov. 24, 1962], No. 46146/63. Heading B5N. Decorative laminates are produced by interleaving a non-impregnated, printed, highly porous absorbent paper, e.g. alpha-cellulose paper, with thermosetting resin-impregnated base and overlay sheets and uniting the layers by hot-pressing. In a modification, the insert is stiffened for easier handling during printing by impregnating it with up to 30%, e.g. 5À4%, of a thermosetting resin, e.g. melamine- or ureaformaldehyde. The insert should have a Tappi porosity of 6-30 secs. per 300 c.c. for fine sheets and a base weight of 14-30 lbs. per 3000 sq. ft. The base sheet is preferably impregnated with 40-55% resin and the overlay sheet with 62-77% resin, suitable resins being those named above. The laminate as described is used with conventional corestock and balancing papers.

Title: Novel block polymers and processes for producing the same
IPC: C08F297/08
Filed: 1965-11-05
Abstract: Block copolymers are made by first polymerizing a C5-C9 branched chain olefin to form a crystalline homopolymer segment, which is then contacted with ethylene in the presence of a catalyst system made by adding a titanate ester to a mixture of a compound of a Group IVA-VIA transition metal and an organic compound of a Group I-III metal, thereby forming a block of ethylene-butene-1-branched chain olefin non-crystalline polymer, the catalyst system having converted part of the ethylene to butene-1 during the course of the reaction.  The reaction sequence may be repeated several times, and the order in which the homopolymer and terpolymer blocks are made may be reversed. The Examples describe the use of catalyst mixtures of titanium tetrapropionate, titanium trichloride and triethylaluminium to prepare block copolymers containing units of ethylene, butene-1, and 4-methylpentene-1 or 3-methylbutene-1.
