Title: Improvements in or relating to low-pressure arc-discharge tubes for use with direct-current supplies
IPC: H01J61/54
Filed: 1953-07-31
Abstract: 736,261. Discharge lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 31, 1953 [Aug. 5, 1952], No. 21293/53. Class 39 (1). In lamps for D.C. operation of the kind having at each end activated electrodes 7, one end only of which is connected to the supply, and starting wall strips 16, 17 connected to corresponding electrodes by conductors 15, an additional conductor 22 is connected to that end of the electrode 7 which is unconnected to the supply and approaches that strip 16 which is connected to the electrode at the other end of the lamp. The glow current between conductor 22 and strip 16 provides an extra heating current for the electrode 7 which assists starting, especially when the polarity of the supply has just been reversed. As shown, the conductor is bent rectangularly and its free end 25 approaches closely the other end of electrode 7, preferably within an oval screen (not shown) which surrounds the electrode. The distance in mm. between the nearest points of the conductor and strip should be between 12/p and 40/p where p is the pressure in mm. of permanent gas (e.g. 3 mm. of argon). The conductor may be of nickel or iron, not tungsten. The 3 mm. strips are of a mixture of graphite and glaze of 25 ohms/cm. A fluorescent lamp is shown with envelope length 120 em. and inner diameter 35 mm.

Title: Improvements in or relating to means for operating brakes on trailer vehicles
IPC: B60T13/36
Filed: 1944-11-01
Abstract: 584,157. Brakes. CLAYTON DEWANDRE CO., Ltd., and WILLETT, S. E. Nov. 1, 1944, No. 21359. [Class 103 (i)] The pipe 1 is connected to the brake system of the tractor A and is joined with a pipe 3 on the trailer B to convey a corresponding fluid pressure to the trailer brake cylinder 6. When the tractor brakes are applied, the change-over valve 26 is set to operate the trailer brakes simultaneously. The pipe 2, which is connected to the compressed air supply on the tractor, is joined to a pipe 4 connected by valves 14, 11 with a reservoir 10 which is kept charged during normal running and is fitted with a safety valve. The valve 14 includes a piston 12 which is kept depressed by air pressure against the action of the spring 13, the passage between the connections 7, 9 being thus kept open. When the trailer is disconnected either intentionally or accidentally, the spring 13 raises the piston 12 to close the said passage, the piston rod 15 raises a sleeve 22 in the valve casing 19. This shuts off the atmospheric port 23 venting the pipe 17, and raises the valve 21 to permit pressure fluid to pass from the pipe 16 to the pipe 17, and by re-setting the valve 26 to the brake cylinder 6. A lever 25 permits the release of the brakes when the two vehicles are disconnected, or the application of the trailer brakes only when the vehicles are connected. The invention may be applied to a vacuum braking system, the reservoir 10 being replaced by a vacuum reservoir and the piston 12 being arranged to operate under suction instead of pressure. In either system, the piston 12 may be replaced by a diaphragm.

Title: Cement clinker
IPC: F27D99/00
Filed: 1977-05-20
Abstract: 1530224 Producing cement clinker PORTLANDZEMENTWERK DOTTERHAUSEN RUDOLF ROHRBACH KG 20 May 1977 [16 June 1976] 21481/77 Heading C1H A process for producing cement clinker involves feeding raw particulate matter comprising limestone, clay, iron oxide and sand to a heat exchanger, supplying heat to the heat exchanger from a downstream furnace whereby the raw particulate matter is heated, and conveying the heated raw particulate matter to the furnace and sintering it therein to form cement clinker by use of a fuel formed at least partly of rubber scrap, e.g. from used motor vehicle tyres. The apparatus includes a cyclone heat-exchanger 4, Fig. 1, a rotary kiln (furnace) 1, exhaust duct 3 from the kiln and a clinker cooler 2. The rubber scrap is reduced to pieces several centimetres in length and breadth in a comminuting device 15. These pieces pass into a carbonization shaft 17 and the resulting carbonization residue enters a fluidized bed 20 formed by relatively coarse ceramic particles. In the bed the carbonization residue is gasified by the action of fluidizing air to form producer gas or water gas. These gases are burnt at a main burner 7 in hot air from the clinker cooler 2 to provide the thermal energy required for the calcination in the rotary kiln 1. The feed of raw particulate matter, which enters the kiln at 26, is preheated in heat exchanger 4 by hot gases exhausted from the kiln through duct 3. Further heat is provided by carbonizing in duct 3 rubber scrap delivered from a bin 8 and burning the carbonized particles at burner 13. For this purpose the carbonization residue is taken off by a conveyer 6 and after removal of ash, is comminuted to fine particles in a device 11 and thereafter blown into the burner 13. In another embodiment, carbonization shaft 17 is replaced by a second fluidized bed 21a, Fig. 2.

Abstract: 920,743. Box making machines. UNIVERSAL CORRUGATED BOX MACHINERY CORPORATION. June 23, 1959 [July 1, 1958], No. 21525/59. Class 18. In a machine for folding the blank shown in Fig. 9 so that panels A, D are adjacent and are secured by an adhesive tab 28, means are provided to ensure that a uniform gap is obtained between the adjacent edges of panels A and D and to ensure that the blank is held square as it passes along a conveyer. The blanks are stacked, as described in Specification 920,744 above a perforated conveyer belt and are held there against by suction, a gauge arm allowing only one blank at a time to pass to a pair of feed rolls 87 (Fig. 1). Guide members 65, 65<SP>11</SP> located the blanks transversely. A handwheel 48 enables the right hand end 52 of the magazine for the blanks to be adjustable to accommodate blanks of various sizes. From the rolls 87 the blanks pass to a pair of belts 105 and are held thereon by rolls 114 (Fig. 17) which are adjustable to suit blanks of various thicknesses. The panels A, D are folded by further belts 138, 139 passing round pulleys 141, 101 and round conical pulleys 147 which cause the belts to twist. One roller 147 is set in advance of the other so that panel A folds before panel D. Adhesive has previously been applied to the tab 28 by a gluing device 117. The means ensuring that there is the correct gap between adjacent edges of panels A and D comprises bevelled wheels 132 carried by a plate 128 (Fig. 17), these wheels press the blank down on to the conveyer belts 105 and also rotate as the blanks pass along so that there is no tendency for the blanks to be drawn out of line on the conveyer which would cause incorrect folding. After folding, the blank is carried between the belts beneath rolls 148, 148<SP>1</SP> which press the belts together and crushing rolls 155 soften the folded edges of the blank. Finally the blanks are discharged from the left-hand end of the machine (Fig. 1). Specification 832,733 also is referred to.

Abstract: 1387292 Luminescent screens PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 May 1972 [12 May 1971] 21536/72 Heading H1D In the manufacture of a colour screen of the index type comprising different colour luminescent strips separated by non-luminescent strips and covered with a metallic layer on which index strips are provided, the strip areas are deposited by photo-resist processes using a light source which is effectively at a point corresponding to a centre of deflection of the electron beam in the completed tube; the centre of deflection is preferably that of maximum deflection. An image of an illuminated mask may be projected on to the screen by a lens system providing an apparent source at the centre of deflection, or alternatively a point or line source of light may be disposed at the centre of deflection to illuminate the screen through the mask which should be convex towards the screen and provided with opaque areas on its convex side. The mask may be made by coating the convex side of a curved support with a photo-sensitive layer which is exposed through a master mask to radiation which passes through the master to the support along paths which would converge at a point corresponding to the centre of deflection. The master mask may be made by a photo-resist process using a lens system to project the image of an illuminated pattern effectively located at a point corresponding to the centre of deflection.
