Title: Improvements in or relating to rolling mills
IPC: B21B39/22
Filed: 1931-02-16
Abstract: 367,173. Rolling. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (United Engineering & Foundry Co.; Farmers Bank Building, Pittsburg, U.S.A.) Feb. 16, 1931, No. 4819. [Class 83 (iv).] A shifting and tilting device comprises two independently movable side guides and a tilting element mounted to move with one of the side guides without being active except when separate tilting mechanism is in operation. The guide 16 is mounted on the headed ends of rack bars 14 so supported by rollers 13 that the top surfaces are just below the surface of the table rollers 11. The rack bars are traversed by pinions 24 on a shaft 25 geared to a motor 27. A second motor 32 is similarly geared to pinions 29 that engage a second set of bars 17 that carry the other guide 22, and also support, at 19 the tilting mechanism, which comprises fingers 33 with stepped edges 34 adapted to move through slots in the guide 22 when lifted by pivotal connection to arms on rack shafts 37 linked at 39 to a head 40 on a rack bar 41 kept in engagement with a pinion 43 in a housing 44 by rollers 50. To avoid actuation of the fingers 33 when the guide 22 is traversed, the shaft 30 carries a pinion 48 equal in size to the pinions 29 and geared to the pinion 43 by an idler 44. The rack bar 41 thus travels at the same speed as the bars 17. When the fingers 33 are to be actuated the housing 44, which is trunnioned about the axis of the wheel 44, is rocked by a link 52 actuated by a crank disc 54 geared to a motor 57. In a modification the rack bar 41 is replaced by a cord 63, Fig. 5, passing over a pulley 62, mounted on a swinging arm 60, and received on a winding-drum 64 in the shaft 30 and of such size that the cord is wound up or paid out according to the movement of the rack bars 17. For tilting, the arm 60 is rocked as by the linkage shown.

Abstract: 1383202 Glass ceramic material PILKING- TON BROS Ltd S LYTHGOE and P S IRLAM 14 Feb 1972 [19 Feb 1971] 5019/71 Heading C1M To manufacture a glass ceramic material in solid shaped form from crystallizable glass of similar form, the temperature of the glass is regulated to a value at which a uniform dispersion of embryonic centres of incipient crystal growth is generated throughout the glass, the glass is supported on a hot gaseous support and is thereafter rapidly heated at a rate of at least 28‹ C. min.<SP>-1</SP> on its gaseous support to a crystallization range of temperature at which it is held to transform the glass to a glass ceramic by fine-grained crystal growth on those embryonic centres. In a first unit 10, glass ribbon or plate, fed on a conveyer 11, is pre-heated up to the temperature T n  at which the embryonic centres form or alternatively newly formed ribbon glass is cooled to such temperature T n . The glass is then fed to a multiple furnace unit 12 in which the glass, plate or ribbon, is supported on a hot gaseous cushion, the unit 12 comprising a centregenerating zone 14 in which the temperature is held at T n , a gradient zone 15 in which the temperature is rapidly raised to the crystallization temperature T c , a crystallization zone 16 in which the temperature is held at T c  to convert the glass to a glass ceramic and a cooling zone 17 in which the glass ceramic is cooled to a temperature at which it can be mechanically handled. The glass ceramic then passes on to a conveyer 20 in a unit 18 where it is further cooled. Temperatures are maintained by burners 21, electrical radiant heaters 22 and regulating fans 23, 24 and 25. The glass ribbon or plate 30 is supported between preforated stainless steel tiles 36, 37 and hot gases are introduced into lower and upper plenum chambers 31, 35, the gases being removed through lateral chambers 38. In the gradient zone 15, driving wheels 40, engaging the edges of the plate 30, are provided in the chambers 38 and mounted on shafts 41 to be driven by means outside the unit 12. The tiles 36, 37 may be mounted on rods 42, 43 with end springs 44, 45 allowing limited movement of the tiles. Gases drawn out of chambers 38 may be recirculated to reduce the number of burners required. The bed formed by the tiles 36 may be gradually curved to form curved glass plates during the passage through the unit 12, the heat for crystallization being enough to cause the flat plate to conform to the gradually changing shape of the tiles. A number of examples are given using glass ceramics of compositions within the following ranges in weight percentages: SiO 2  54À8-71À6; Al 2 O 3  14À0-28À5; Li 2 O 2À5-12À1; TiO 2  0-3À7; ZnO 0-3À6; ZrO 2  0-6À8; CaO 0-0À3; MgO 0-2À9; K 2 O 0-2À5; Na 2 O 0-0À5; B 2 O 3  0-4À4; P 2 O 5  0-4À2 and F 0-2À0. Specification 1,383,201 is referred to.

Title: Means for governing the road speed of a motor vehicle
Inventor: TOPPING HERBERT JOHN
IPC: B60K31/00
Filed: 1959-02-14
Abstract: 881,244. Controlling motor vehicles. ROVER CO. Ltd. Feb. 11, 1960 [Feb. 14, 1959], No. 5226/59. Class 79(5). The road speed of a vehicle propelled by an internal combustion engine is limited to a predetermined value by a device which includes a switch operated by a governor driven at a speed commensurate with the vehicle road speed, the switch being in circuit with a solenoid of which the armature actuates the engine fuel supply control means at the predetermined speed to reduce the fuel supply. The engine 13 drives a governor 14 and speedometer 12 through a cable 11. A rod 28 connected to the accelerator pedal, when moved to the left, Fig. 1, opens the butterfly valve of the carburettor 20 through bell crank 23, link 22 and lever 21 fast with the butterfly valve. The bell crank 23 is urged into contact with a link 27 to which the rod 28 is connected so that the bell crank and link normally move together. The armature 17 of a solenoid 16 is connected through a spring 18 to a lever 19 fast with the lever 21 and butterfly valve of the carburettor. When the solenoid is energised at a predetermined speed, the lever 19 is moved in a clockwise direction to close the butterfly valve, the bell crank 23 being separated from the link 27 against the pressure of spring 24. The solenoid 16 is in circuit with the ignition switch 15. The control circuit is shown in Fig. 2, a relay 29 closing switch 14a when the ignition circuit is completed, and contacts 29a being open. At the predetermined speed, the governor opens 14a thus de-energising the relay which closes 29a to energise the solenoid. An alternative circuit, Fig. 3, may be provided so that the predetermined speed may be temporarily exceeded. A time delay circuit includes a bimetal heating element 30 in series with a normally closed contact 30a and push button switch 31 and in parallel with a relay winding 29 and governor contacts 14a. A relay 32 having normally open contacts 32a is shunt connected to the element 30. The second relay also has a normally closed contact 32b in series with the governor contacts 29a. The governor controls the contacts 14a and 29a as before, but if it is desired to exceed the predetermined speed, the push button 31 is depressed energising the element 30 and relay 32 causing contacts 32a to close whereby the heating circuit is held when the push button is released and contacts 32b to open breaking the circuit through the solenoid 16. At the end of a predetermined period determined by the bi-metal strip 30, contacts 30a are opened to de-energise the relay 32 and thereby close contacts 32b and re-establish speed control by the governor and also contacts 32a re-open to re-set the time delay circuit. Due to hysteresis, the element 30 will not become fully effective for re-use until it has cooled. In a compression-fired engine the solenoid may control the fuel pump.

Title: Improvements relating to phosphors
Inventor: SHAW JACK VERNON
IPC: C09K11/00
Filed: 1964-05-07
Abstract: The after-glow of a zinc magnesium fluoride phosphor excited by an electron beam is modified by slight abrasion of the phosphor granular surfaces so that it remains for a time (e.g. 0.2 sec.) at a substantially steady (e.g. 80%) level of visible light intensity, and then decays at a rapid rate (e.g. down to 20% in 2 sec.).  The abrasion may be produced by wet mill rolling. To reduce dissociation of the phosphor under electron bombardment, the particles may be coated with e.g. silica, magnesium oxide, or zinc ortho-silicate to absorb some of the beam energy.  This coating may be applied only to the beam side of the particles of a screen.
