Title: An improved method of and means for differentially tempering a glass sheet
IPC: C03B27/052
Filed: 1960-10-10
Abstract: 890,269. Tempering glass sheets. COMPAGNIE DE SAINT-GOBAlN. Oct. 10, 1960 [Oct. 9, 1959], No. 34680/60. Class 56. In differentially tempering a glass sheet to produce a fragmentation barrier therein, the sheet is screened, during the heating stage of the tempering process, to give two pairs of spaced zones extending inwardly from the periphery of the sheet and a further zone extending at least from between the inward ends of one pair of spaced zones to at least between the inward ends of the other pair. A sheet 1 of glass is suspended within a furnace with metallic screens 2, 2<SP>1</SP> mutually opposed on each side of the sheet terminating just short of the edges, 3, 4 thereof. Two pairs of screens 5, 5<SP>1</SP> and 6, 61 at each edge are of U shape to give two elements 7 straddling the ends of each screen 2, 2<SP>1</SP> and extending beyond the adges 3, 4. The screens are cooled by an inner metal tube 8 through which water is circulated, the screens 5, 5<SP>1</SP> and 6, 6<SP>1</SP> being secured thereto by bolts 16 and the screens 2, 2<SP>1</SP> closely overlying the tube on two sides 9,10, but the side 13 parallel with the glass sheet 1 being spaced from the corresponding side 12 of the tube 8. In order to vary the cooling effect, the spacing between sides 12 and 13 can be adjusted by bolts 15 sliding in slots 14. To reduce the heating effect of the furnace, the outer faces of the screens 2, 5, 6 may be chromed to increase heat reflectance and to increase their heat absorbing power, the inner faces adjacent the -sheet 1 may be blackened. In place of screens on both sides of the sheet 1, one set only may be used, in which case thin coverings may be placed on the opposing side of the sheet, the coverings being preferably opaque and coloured.

[Class 80 (ii)] Forward drive is transmitted from a driving shaft 1, Fig. 1, to a driven shaft 2 by a number of inter-wound helical springs 3 which frictionally engage both shafts, or which frictionally engage the shaft 2 and are secured to the shaft 1. The end 4 of each spring engages a slot 5 in a surrounding sleeve 6 which is itself encircled by a helical spring 7, the end 8 of which is secured to a fixed member 9, whereby, on reverse rotation of the shaft 2, the spring 7 tightens on the sleeve 6 so as to prevent the transmission of such reverse rotation to the shaft 1. Alternatively, the sleeve 6 may have ratchet teeth co-operating with a detent pawl. The springs 3 may grip the shaft or shafts through the intermediary of a split friction sleeve or sleeves. As shown in Fig. 3, the springs 3 engage recesses in the members 1 and 2, the sleeve 6 being replaced by a shaft 14. A flywheel may be fitted as in Specification 420,306. Specification 386,358 is referred to in the Provisional Specification.

In a servo assisted clutch release mechanism of the type described in the parent Specification 1,174,598, wherein a pneumatic servo 11 acts through a combined servo-piston and slave cylinder 14 on a clutch release lever (not shown), the servo 11 is controlled by a valve 70 responsive to the pressure in a line 27, 29 between a master cylinder (not shown) and the slave cylinder 14. On depression of a clutch pedal (not shown) the pressure in the line 27, 29 rises and at a first predetermined pressure acts on a land 76 to move a valve spool 71 down against the bias of a spring 74 and commences opening an inlet part 36 whilst closing an exhaust part 41. As the pressure in the line 27, 29 continues to rise the parts 36, 41 are progressively opened and closed respectively until at a second predetermined pressure the exhaust part 41 is fully closed.

Combined drawing and twisting arrangements; rollers and roller h e a d s ; spindle apparatus; moistening; spindle-driving apparatus.-Roving from a revolving bobbin is simultaneously drawn and twisted by a drawing-apparatus which rotates at or approximately at the same speed as the supply-bobbin, and the spun yarn is continuously led for treatment by any subsequent process until the supply-bobbin is exhausted. A spindle 3, 3a, Fig. 1, driven by a wharl 22 carries a holder 2 for the roving and a drawing- apparatus 4, and the roving 1 passes over or around an abutment 5 which serves to retain the twist. The drawing-apparatus is driven through gearing, comprising a draft change wheel 16 and a twist-change wheel 32, from a wharl 27 and comprises, as shown in Fig. 1, drawing- rollers 11, 12, retaining-rollers 6, 6<a>, one or more straps 7, an adjustable breast-plate 8 and guides 9, 10, shown in detail in Fig. 5, for the straps and the roving. The wharls 22, 27 mav be driven by a single band 39 tensioned by a pulley, as shown in Fig. 7. The drawing-apparatus is modified to suit the kind of fibre being treated, and may comprise a single row of gills and fallers. For wet spinning the breast-plate is dispensed with and hot or cold water is led by a pipe into the holder 2. For cotton spinning three pairs of rollers weighted by saddles and springs are employed. The holder 2 may be mounted on a driven spindle separate from that which carries the drawing-apparatus, as shown in Fig. 15, and the roving may be removed from its bobbin and the end drawn from the inside or outside of the roving-mass.

Abstract: 1,097,752. Electromagnetic fuel injection valves. ASSOCIATED ENGINEERING Ltd. Sept. 9, 1964 [Sept. 9, 1963], No.35495/63. Heading F1B. In an electromagnetically operated fuel injection valve, fuel pressure is used to assist valve opening. Pressurized fuel is fed through inlets 48, 49, Fig.2 and whilst solenoid valve 45 is deenergized the valve 42 is hydraulically unbalanced thereby assisting spring 47 to keep the valve in the closed position. On energizing solenoid 45 the servovalve 44 closes inlet 48 and opens outlet 50. The valve stem now moves off its seating due to the increased force acting on the underface of the enlarged upper end 42a to allow fuel injection. In another embodiment one or more fuel injection valves V1, V2, V3, Fig.3 are opened by a single electromagnetic control arrangement 27, 28 in which the spring-loaded armature 27 normally closes passage 25 when solenoid 28 is de-energized.

Abstract: 449,026. Coated fabrics. IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Dec. 18, 1934, No. 36313. Convention date, Dec. 19, 1933. [Class 140] Containers, envelopes, wrappers, &c. are made from paper coated firstly with an adhesive composition containing uncured rubber, and secondly with a powdered material such as starch or soapstone adapted to prevent adhesion of the rubber composition to a similar surface under slight pressure, but allowing adhesion under greater pressure. Suitable rubber compositions are (1) Pale crepe rubber, barytes and agerite white, (2) Pale crÛpe rubber, barytes, whiting, zinc oxide, montan wax, stearic acid and rubber oil, and these are preferably applied to the paper by a calendering operation, while the starch may be applied in a usual type of starching box, excess being removed by brushing. The containers are made by placing together blanks, and applying sufficient pressure to fracture the starch covering, to the regions where adhesion is required. This seal can be readily broken and resealed, or it may be made permanent by a vulcanizing treatment.
