Patent GB-1058650-A (GB)
Title: Preparation of olefinically unsaturated esters by a dehydrogenation process
Inventor: DEWING JOHN
IPC: C07C69/54
Filed: 1964-09-04
Abstract: Unsaturated esters are prepared by heating a saturated or partially unsaturated ester, e.g. a methyl or ethyl ester of an aliphatic (C3-C4) acid, with iodine.  The iodine may be elemental or generated in sity by the oxidation of lithium, lead or cadmium iodides. Catalysts, e.g. calcium, nickel, iron, manganese oxides or mixtures thereof may be present.  Examples describe the heating of iodine and ethyl isobutyrate to yield ethyl methacrylate with a minor proportion of vinyl methacrylate, and the heating of methyl propionate with iodine to yield methyl acrylate.

Title: Improvements in or relating to water gas generators
IPC: C10J3/76
Filed: 1929-12-02
Abstract: 333,842. Breisig, A. Dec. 3, 1928, [Convention date]. Producers. - Part of the, waste blast gases leaving a water gas generator 1 pass to a steamsuperheating regenerator 6 which is situated below a vaporizer 7, and the remainder pass to regenerator 8 connected to a waste heat boiler 10. During the run, the regenerator 8 is swept over by a carrying gas, which may be a part of the water gas produced, to supply the stored heat to the boiler, the latter thus being heated both during blasting and steaming. The boiler may surround the combustion chamber of the generator. In a modification in which two generators are used, each is connected to a regenerator for the. production and superheating of the steam, and from these regenerators ducts lead to a single regenerator which supplies surplus heat to a boiler.

Abstract: 895,856. Photographic copying cameras. DACQUAY, H. Nov. 20, 1958 [Dec. 6, 1957], No. 37335/58. Class 98(1). In a copying camera the diaphragm aperture adjustment is mechanically controlled by the relative displacements of the lens front and camera back or object carrier so that an increase in magnification is accompanied by an increase in diaphragm aperture. As shown, slide bar 9 has finger 11 engaging in channel guide 12 which is adjustably mounted on bench 1. As the objective carrier 3 is moved along the bench 1, the diaphragm aperture is altered by means of connecting rod 5. A slide (Fig. 3a, not shown), for inserting an apertured diaphragm plate into the lens mount 4 and simultaneously positioning a lamp in front of the lens is described. The plate aperture is smaller than the smallest adjustable aperture, and the lamp is used to give a preliminary printing exposure of a screen arranged in front of the photographic element. The duration of the exposure is varied by rod 17 adjusting clockwork timer 15 in response the movements of slide bar 9. If the back of the camera or object carrier are not fixed in relation to the bench, the guide 12 may be fixed to the movable member.

Heading B5K Veneers 11 are glued edge-to-edge by introducing a measured dose of powdered glue or adhesive into a gap between adjacent veneers and heating the glue or adhesive whilst the veneer edges are pressed together. In one embodiment, Figs. 1 and 3, the veneers 11 to be glued together are pushed towards a dosing device 13 and move into contact with a stop ledge 12 which determines the jointing space between them. The device 13 comprises a hopper 22 containing powdered glue 21 kept in a loose condition by a disc 25 fitted with pins 24 which are rotated by engagement with semicircular or angular-section grooves 18 in a rotating disc 17 which feeds a dose of glue into the gap between the veneers. Preferably the thickness of the disc 17 corresponds to the width of the joint. The veneers are fed between heating devices 32, 33 by a steel conveyer 28 driven by pins 30 on a disc 26 engaging recesses 29 in the conveyer edges. The device 32 transmits radiant heat to the upper run of the conveyer 28 which transmits heat to the moving veneers 11. Heat from the device 33 is transmitted to press rollers 34 connected by straps 36, Fig. 3, to form a chain and which are provided with " herringbone " scores 37 to press the veneers together to form a butt joint. The device 33 and the rollers 34 are resiliently mounted in a frame 39. A scraper (not shown) may be provided to clean the belt 28. In another embodiment, Fig. 4, the conveyer 28 is replaced by pairs of discs 40 below the veneers 11 and upper resiliently-mounted pressure rollers 41. The discs 40 are driven in synchronism with the rotation of the disc 17 by a belt drive 43 but the speed of the disc 17 is adjustable relative to the discs 40 by a control disc (48), Fig. 5 (not shown). The axis of rotation of each roller 41 is arranged in front of the axis of rotation of each corresponding disc 40 to press together the veneers. Heating devices 46, 47 directly contact the veneers 11.
