Title: Thermal treatment of pitch
Inventor: WADDINGTON WRIGHT
IPC: C10C1/19
Filed: 1961-10-09
Abstract: A process for the thermal treatment of pitch comprises bringing the pitch into direct contact with a liquid metallic heating medium which does not react with, dissolve in, or dissolve pitch, e.g. molten lead, or a molten lead alloy. The period of contact may be from 5 to 60 minutes at a temperature between 330 DEG  and 450 DEG  C.  The lead may be alloyed with tin. The pitch may flow over a static surface of the heating medium, or be in cocurrent or countercurrent flow.  A scraper may be used to clean the pitch/heating medium interface. Volatile oils produced may be removed, condensed, and returned to the heating zone.

Abstract: 867,911. Valves. DUNLOP RUBBER CO. Ltd. Nov. 18, 1957 [Dec. 1, 1956], No. 36796/56. Class 135. An inflation-type valve comprises a tubular housing 1 having a longitudinal passage 8 therein opening into a chamber 13 accommodating a cylindrical block 17 of resilient material, the latter being freely movable in the chamber and constituting the valve closure member. A plurality of holes 15 extend radially from the walls of the chamber 13 to permit the passage of fluid when the block 17 is moved to the lefthand end of the chamber due to the passage of fluid under pressure through the valve. Reversal of fluid flow is prevented by the block moving to seat on a frusto-conical seating 14. The valve may, as shown, be accommodated in a conventional tyre valve stem or it may be provided with peripheral grooves to engage the neck of an inflatable article, such as a football. The valve may also be used as a charging valve for substantially rigid containers.

Abstract: 846,594. Applying adhesive strip. KIND, E., [trading as METO-GESELLSCHAFT KIND & SOHNE.]. Dec. 2, 1957, No. 37522/57. Class 73. [Also in Group XVII] An adhesive strip dispenser carries a roll 1 on its body rotatable relatively thereto and has means for ejecting and retracting one end of the strip 20 through an aperture 7 so that the end can be pressed on to a surface, a length being dispensed by moving the dispenser and the end being retracted after severance. The roll 1 is mounted within a casing 2 bearing an extension 5, through the slit 7 in the top 6 of which extends a slide 8. A recess 9 within the slide, see Fig. 4, has a shoulder 10 engaged by a spring 11 of which the other end bears against a projection 14 on the casing wall. A stirrup 16 secured by a screw 17 extends from the lower end of the slide, and between its arms 18, 19 is mounted a guide-roller 21; the strip 20 passes between the roller 21 and an extension 23 of the arm 19. To operate, the slide 8 is depressed into the casing until a shoulder 8c can be retained by a projection 27, so that the roller 21 is near the aperture in the casing and presses the strip 20 into the required surface while the dispenser is rolled along. When sufficient strip is applied, the dispenser is fitted with a roller 29 at the top end of the slide 8 bears against the surface causing the shoulder 8c to disengage so that the spring 11 returns the slide until a further shoulder 8b is engaged by the projection 27. By moving the dispenser further, the strip 20 is engaged against the slit edge 26 and is severed thereby.

Title: Method of and installation for automatically cutting and discharging a continuous glass ribbon leaving a vertical drawing machine
IPC: C03B33/02
Filed: 1960-11-01
Abstract: 912,008. Cutting glass. GLOVERBEL S.A. Nov. 1, 1960 [March 23, 1960], No. 37523/60. Class 56. A strip of glass emerging upwardly from a vertical drawing-machine is cut by gripping it at the top, bending it slightly one way to engage a device for scoring it then bending it the other way to break it and finally carrying away the severed portion in a vertical position. In the form shown in Fig. 1 the upper edge 61 of a sheet 62 emerging from a drawing-machine 60 is secured in a clamp 1, shown in detail in Fig. 4. The clamp comprises a fixed jaw 2 and a movable jaw 3 operated by a piston 23 in an air cylinder controlled by an electromagnetic valve 27. Both jaws carry shock-absorbing members comprising steel tubes 29 covered with rubber tubes 31, which may be inflated. The whole clamp is carried on a rod 4 supported between members 5 slidable on rods 7 forming part of a frame 9 suspended from carriages 10 on rails 11. The clamp is suspended from cables on drums 15 driven by an electric motor and reduction gearing, not shown. The frame 9 can be reciprocated along the rails 11 by a crank driven by a motor and reduction gearing, not shown, and coupled to the frame through a link 33. The crank-shaft has a brake operated by an air cylinder to stop the framework 9 when required. Starting from the position shown in Fig. 1, the clamp 1 is operated to engage the upper edge of the glass and is then carried upwards at a speed appropriate to the drawing speed, by applying the appropriate motor torque to the drums 15. As the leading edge of the glass passes a first abutment 65 a switch is operated to move the frame 9 to the left to engage the glass with the cutting device 63, which may be as described in Specification 690,262. When it passes the abutment 66 the cutting device is operated. The abutments are adjustable in accordance with the size of cut sheet required, as described in Specification 847,892. The frame is then moved to the right, while the lifting is slightly accelerated, to break the scored sheet against the abutment 64 and carry it to a conveyer (Fig. 6). The sheet is placed first on a ledge 76 forming part of a table 70 pivoted at 74 and composed of parallel girders 71. It is detached from the clamp 1 and the table lowered about its pivot by a motor 82 driving through reduction gearing 81 a crank 79 coupled to the table through a link 78. The table is lowered until the girders 71 pass down between a number of spaced, continuouslyrunning belts 84, driven by a motor 97, to which the sheet is thus transferred. While on these belts the sheet may be scored longitudinally by means described in Specifications 606,481, 606,479, and 606,452. The various parts return to their original positions and the cycle is repeated. Switches operated by parts of the mechanism control movements of other parts in correct sequence, the whole electrical system being described in detail in the Specification.
