Patent GB-963458-A (GB)
Title: Production of unsaturated aliphatic alcohols
Inventor: YEOMANS BERTRAM
IPC: C07C33/03
Filed: 1962-05-10
Abstract: Unsaturated aliphatic alcohols are prepared by dealkoxylating an alkoxy derivative of the corresponding saturated aliphatic alcohol in the vapour phase at an elevated temperature in the presence of a catalyst comprising an oxide of an element of Group II of the Periodic Classification. The preferred alkoxy derivatives are the methoxy ones and the preferred catalyst comprises magnesium oxide containing traces of magnesium carbonate. Preferably the process is carried out at a temperature of at least 250 DEG C. Suitable starting materials are, for example, 3-methoxy propanol and 3-methoxy-n-butanol which yield allyl alcohol and crotyl alcohol respectively.

Abstract: 788,676. Heating buildings electrically. PANELEC (GREAT BRITAIN), Ltd. June 27, 1956 [June 27, 1955], No. 18508/55. Class 39(3) Floors of a building are heated by placing an electric heating cable in metal tubes 2 joined in axial alignment and having longitudinal fins 3 from which extend integral flanges 4 lying in a plane outside the tubes 2, and a metal heat distributing layer e.g. of expanded metal is attached to the flanges, the whole being embedded in a concrete slurry or the like of a floor or wall. The tubes are of steel,. aluminium, copper or brass and are formed as shown in Fig. 3 as a unitary structure e.g. by rolling. The sheet of expanded metal or wire mesh is attached to the flanges 4 either by tongues cut and bent up .from the flanges or by metal washers wider than one flange 4 and attached thereto by screws. The fins 3 may be welded together at intervals, or one flange may be bent to extend over the other and be folded over the edge of the other, in which case the fins need not be brought together. The heating cable has a sheath either non-metallic or of metal e.g. lead or aluminium and is withdrawable from the tubes. The ends of two aligned adjacent tubes may be joined by a metal sleeve inserted as a sliding fit into the ends of the tubes, thus allowing expansion of the tubes. The metal sleeve may have a circumferential enlargement preventing contact between the ends of adjacent tubes, which may be tapered. Alternatively the sleeves may be slipped over the tubes 1, the sleeve then being slotted to clear the fins 3. An end sleeve for connection to a terminal box may be externally threaded. The tubes and sleeves may be oval in cross section.

Title: Bag-making Machine
IPC: B31B160/20
Filed: 1967-04-24
Abstract: 1,179,362. Making block bottomed bags. WINDMOLLER & HOLSCHER. 24 April, 1967 [5 May, 1966], No. 18819/67. Heading B5D. A bag-making machine in which tube sections are conveyed longitudinally and which comprises a bottom-making cylinder 1 on which the leading edge of the bottom ply is held by grippers 17 when the other ply has been lifted while a pulling-open device 36 pulls open the other ply to form an open-crossed bottom or block bottom, and lateral grippers 44, 44<SP>1</SP> retain both plies of the tube section 41 and the ends of the bottom centre line, is characterized in that there is a relative radial movement between the end grippers 17 and that part of the periphery of the cylinder 1 between the end grippers and the lateral grippers 44, 44<SP>1</SP>, such movement being so controlled that the workpiece ply held by the end grippers is flat in the region between the end grippers and the lateral grippers during the pulling-open operation and is caused to contact the peripheral surface of the cylinder after the pulling open operation. In one embodiment the end grippers 17 are carried on levers 13, 13<SP>1</SP> forming part of a linkage controlled by fixed cams 10, 10<SP>1</SP> so that during pulling-out the grippers are moved outwardly of the surface of the cylinder 1 so that the bottom ply of the tube section between the end grippers 17 and lateral grippers 44, 44<SP>1</SP> lies in a plane tangential to the cylinder surface. The opening template 36 is controlled by a cam 23 to move so that it does not strike the grippers in their raised position. In a modification, Fig. 3 (not shown), the template is fixed as usual and the segment of the cylinder surface between the end grippers and the lateral grippers are moved radially inwardly during the pulling out operation so that the section of the bottom ply can lie in a flat plane across the recess so formed. The various linkages are adjustable so that bags of different sizes may be made on the same machine.

Title: Improvements in mine roof supports
IPC: E21D23/00
Filed: 1953-07-08
Abstract: 745,679. Mine roof supports. DOWTY AUTO UNITS, Ltd., and FRYE, C. M. July 8, 1954 [July 8, 1953], No. 18977/53. Class 20(2). In a mine roof support of the " walking prop " kind in which two roof-supporting structures, each comprising a group of hydraulically operated props, are interconnected by driving mechanism so that the structures can be freed and displaced in turn to advance the roof support, the pressure chamber. of each prop communicates individually with a source of pressure liquid through a non-return valve which prevents flow from the chamber to the source and also communicates individually with the inlet side of a pressure relief valve through a non- return valve which prevents flow back to the chamber, the relief valve being common to all the pressure chambers of the group. The two structures 11, 12 are diagramatically represented in the drawing as having floor bars 13, 14, roof bars 15, 16 and props 17. Projections 19, 20 from the two structures are inter-connected by a hydraulic jack 18, supplied from a source of fluid pressure 21 through a pipe 22 through a selector switch 23. The pressure may be selectively connected to either side of the piston of the jack through one of the pipes 24, 25 the other pipe then being connected to the return pipe 26. Supply and return pipes 27, 27a, from pipes 22, 26, are connected through non-return valves 29 and pipes 28 to the props 17. The pipes 28 are also connected through one-way valves 30 to a pipe 31 which is connected through a pressure-relief valve 33 to the return pipe 27a. The relief valve is by-passed by a stop valve 40 and a similar stop valve 39, ganged to it, is provided in the supply pipe 27. Pressure is applied through valves 29 which prevent flow back into the pipe 27. The pressure prevailing in the prop carrying the greatest load will prevail in the pipe 31 but will be prevented from being transmitted to the other props by valves 30. However, when a predetermined load is reached the relief valve 33 allows the fluid to escape into the return pipe 27a. The single relief valve is thereby capable of giving relief to any one of a number of props which are overloaded. The valves 39, 40 are ganged so-that one opens when the other closes. To advance the support the valves 39, 40 of structure 11 are operated to close the supply line and open the return line so that pressure on the props is released. The selector valve 23 is then operated to expand the jack 18 and the pressure is re-applied to the props of the structure 11. The structure 12 is drawn up in the same way except that the valve 23 is turned in the opposite direction to contract the jack 18. Specifications 658,998, and 671,955 are referred to.
