Title: Source of thermally excited radiant energy
Inventor: MOORE JOHN ALFRED
IPC: H05B3/64
Filed: 1960-04-11
Abstract: 921,234. Electric heating resistances. GENERAL ELECTRIC CO. Ltd. July 7, 1961 [April 11, 1960], No. 12905/60. Class 39 (3). A source of radiant heat includes at least one radiator element forming an array of slots and having an L-section over a part of its length at least, the element being heated by the passage of an electric current through it. In the example shown in Fig. 1, the source is in the form of a square open-fronted box 1 containing two radiator elements 2, 3; the box is constructed of refractory metal, such as stainless steel, and may be provided with water cooling (not shown). Each element is constructed of tungsten and may be arranged as shown in Fig. 2 in the form of a ribbon 6 having flanges 7 and tungsten terminal blocks 8 at either end, the ribbon being supported by tungsten stirrups 9 mounted on rods 10 embedded in alumina blocks (not shown). The width of the flanges 7 and the spacing between adjacent sections of the ribbon is less than the width of the ribbon. An alternative form of heating element of a similar type is described and illustrated in Fig. 4 (not shown). Protective gas for the elements, such as nitrogen, is supplied to the box 1 through an inlet (not shown) and the flow of gas from the box is restricted by a screen of fine wires 4, 5 (as described in Specification 921,233, which may be heated by passing an electric current through them. Alternatively, the mouth of the box may be provided with a screen of re-crystallized alumina. The inner faces of the box are protected by sheets of molybdenum foil (not shown) and the box is designed to permit assembly of a number of similar boxes to form a source of any desired area.

Filed: 1971-05-04
Abstract: 1356196 Structural joints SVENSKA FLAKTFABRIKEN AB 4 May 1971 [29 May 1970] 12969/71 Heading F2M [Also in Division E1] A connector for interconnecting adjoining perpendicular clamping frame members for joining together ceiling and wall elements, for example as in Specification 1,305,877, comprises a first U-section and a second U-section, each formed with a base or web 4 or 6 and a pair of side walls 5 or 7, joined by an intermediate piece 8 which is a narrower continuation of both the webs, is contained within the height of the walls 5 of the first U-section, and is arranged and formed so that the planes of the webs 4, 6 are at right angles. As shown the intermediate piece is parallel to web 6 from which it is spaced by the thickness of the wall 2a of the wall element clamping member 2 or the corresponding wall of the floor mounted strip 3. To provide a smooth junction between perpendicular clamping members, or ceiling and wall members 1, 2, the edges of the side walls 7 of the connector are displaced relatively to the top edges of the walls 5 and web 4 by the thickness of the flanges 14 of the ceiling clamping member 1. The connectors which are inserted into the square C clamping members 1, 2 are locked therein by bent out lugs 9, 10 engaging in holes 11, 12 in the members 1, 2 or in hole 13 in the floor member 3. Heat and sound insulating panels held together by such clamping members may form the walls and ceiling of a machine room. The connector may be formed by cutting and bending metal sheet. A modified connector in which the portions 7 remain coplanar with the web 6 may be used to join a strut with the cross-section of a clamping member 1, 2 to a plane surface, e.g. a plate or concrete, by securing the plane member thereto.

Abstract: 544,045. Elastic diaphragm pressure gauges. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Aug. 20, 1940, No. 13250. [Class 106 (ii)] An initial stress is applied to the diaphragm by resilient means which has a stiffness of the same order as or less than the stiffness of the diaphragm. A resilient diaphragm 10 is clamped at the flange 11 of a plate 12 to form a chamber 13 to which pressure fluid is admitted through the pipe connection 14. The flange 11 is clamped to one flange 15 of a tubular distance piece 16 the other flange 17 of which has clamped to it by a ring 19 a second diaphragm 18. The diaphragms are connected at their centres by an adjustable coupling. This comprises a part 20 having a hollow spigot 21 screwed to receive a screw 23 with a head 30. The screw 23 is rotatable in a socket 24 formed with a flange 25 against which the diaphragm 18 is clamped by a nut 26. A socket extension 27 slides on the part 21 and is surrounded by a tubular rubber packing 28 between the flanges 25, 29. The diaphragm 18 exerts an initial stress on the diaphragm 10 which may be adjusted from outside by turning the head 30. A strut 33 pointed at the ends which engage jewelled bearings 32, 34 transmits motion of the diaphragm to a spring pulled pointer 31. The hollow distance piece is open at 36 but may be closed and connected to a second source of pressure.

Title: Manufacture of bismuth salts
IPC: C07C61/13
Filed: 1935-05-03
Abstract: Bismuth salts soluble in oil are obtained by causing a basic bismuth salt of phenylacetic acid, salicylic acid, or acetylsalicylic acid to react with an organic acid capable of forming a bismuth salt well soluble in oils.  The reaction may be carried out in the presence of an oil such as olive oil, earth nut oil, beech nut oil, sesame oil, rapeseed oil, or bone oil to obtain the solution directly.  In a modification, one molecular proportion of the sodium salt of an acid of the first group and two molecular proportions of the sodium salt of an acid of the second group may be reacted with a bismuth salt such as the nitrate in an aqueous medium.  Acids of the second group comprise the hydroaromatic endomethylene benzoic acids described in Specifications 374,818 and 428,147, camphocarboxylic acid, naphthenic acid, abietinic acid, carboxylic acids of terpenes, amylmalonic acid mono-ethyl ester, and undecylmalonic acid mono-ethyl ester.  In examples, camphenilanic and campholytic acids are employed, and bismuth nitrate when used is dissolved in water and glycerine or mannite.  The Specification as open to inspection under Sect. 91, comprises also the following subject-matter: the use, in place of phenylacetic acid, &c., of phthalic acid monobenzylester, oleic acid, stearic acid, succinic acid monobenzylester, anthranilic acid, and tetrahydrobenzoic acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,139,156. Machinery safety devices. MAY-PRESSENBAU G.m.b.H. 22 March, 1967 [26 March, 1966], No. 13506/67. Heading F2J. A safety device for a press having a ram 16 driven from a crank-shaft 24 by a connecting rod 20 comprises a pivoted safety member 50 which, on an unwanted stroke of the press, blocks the path of a stop 32 on shaft 24, the member 50 then acting on a push rod 72 which causes extrusion of a deformation member 66, thereby absorbing the energy of the machine. The safety member 50 is moved to and from its blocking position by a compressed air operable cylinder piston system 52. Three electro-switches 86, 88, 90 are arranged to be actuated by cams 96, 98, 100 fixed to a follower 58 of control member 52. Safety member 50 moves to its safety position if a power failure occurs, or if the machine control is switched off, the control circuit being closed in this position by switch 88. If the machine is switched to singlestroke operation and the operating buttons are pressed, the control device 52 rotates the safety member 50 to its release position, shown dotted. In the final phase of this rotating movement, cam 96 engages switch 86 which closes a circuit for starting the machine. When ram 16 reaches its lower dead centre position another switch actuates control device 52 so that safety member 50 is returned to its blocking position. When safety member 50 is lowered by stop 32, the circuit for the drive of the machine is switched off by cam 100 engaging switch 90, so that the drive is not subjected to any further load or stress if the working ram is blocked.
