Title: Improvements in or relating to electrical heaters for rooms
IPC: F24H3/00
Filed: 1936-07-23
Abstract: 478,670. Electric radiators and air heaters. WILLIAMS, E. T. July 23, 1936, No. 20435. [Class 39 (iii)] An electric heater comprises a casing 1 with an air inlet near the bottom and an air outlet near the top, and the heating elements 7 can be moved relative to the casing so that their heat may be radiated directly into the room or the heat may be directed to heat the air in the casing and cause the apparatus to act as a convection heater. The heating elements may also occupy intermediate positions in which some heat is radiated into the room and some is used to heat air. In a modification the elements are fixed but reflectors are moved round the heaters to change the direction of the heat emitted and produce the effect of moving elements. The elements 7 are provided with cranks 10 connected by a rod 11 in order that the elements may move together. The wall 15 on which the heat of the elements is directed in the convection heating position is protected by a plate 14 which creates a heat insulating air space. Switch means connected with the means for moving the elements may be provided to reduce the heating effect when the apparatus is used as a convection heater.

Title: Improvements in or relating to roll mountings in calenders
IPC: B21B29/00

Abstract: 974,374. Bearings. BELOIT CORPORATION. May 28, 1962 [Nov. 9, 1961], No. 20475/62 Heading F2A. [Also in Division D2] A method of altering the deflection of a roll in a vertical calender stack in which the ends of the roll are rotatably supported in a pair of bearings enclosed within a housing comprises applying a force couple to the housing without subjecting the bearings to a force in the direction of the roll axis. As described, the method is applied to the top roll 14 and the bottom roll 11, and optionally to the intermediate rolls, of a calender stack 10. Housing 28a of roll 11 is pivoted at 31a and has a lever arm 29a on which a fluid actuated diaphragm 33a acts to produce the force couple. The housing 28a is mounted on tracks 35, 36 (Fig. 2, not shown), so that its position lengthwise of the roll may be adjusted, while diaphragm 33a may also be adjusted lengthwise. Pivots 39a and 39b of the top roll, may be adjusted vertically-to alter the load along nip N-3-and horizontally. The weight of the bearings 16, 17 of the intermediate rolls 12, 13 are offset-as in Specification 818,429- by means of a fluid-actuated diaphragm 22 (Fig. 2) urging upwards a pivoted arm 18 or 19, on which the bearings are mounted. Bottom roll 11 may have a negative crown-i.e. have a smaller diameter at the centre than at the ends. Specifications 681,524 and 820,225 also are referred to.

Title: Processes for fixing pigments on fibrous materials, fabrics and foils
IPC: D06P1/44
Filed: 1962-05-28
Abstract: Pigments are fixed on fibres, fabrics or foils by applying a print paste or padding liquor containing, as binding agent, a high molecular polycondensation product containing more than two thiosulphate groups which can be cross-linked to form a disulphide substance under the influence of an alkali, if desired at elevated temperature, and drying and fixing by a thermal treatment in the presence of an alkali or substance forming alkali when heated.  The fixation may be effected in three ways: (1) by passing the material through an alkaline bath at 60-100 DEG C. which may also contain an organic sulphur compound (many specified), (2) by steaming at 98-102 DEG C. and (3) by dry-heating at 90-200 DEG C, in cases (2) and (3) the liquor or paste contains the alkaline agent. The liquors or pastes may also contain a polyalkylene polyamine as well as a synthetic resin especially an aqueous dispersion of a butadiene/acrylonitrile or styrene/butadiene copolymer.  Known thickeners may be employed and the pigments may be organic or inorganic.  The materials to be coloured may be paper, cardboard, fibres of natural or regenerated cellulose, acetylated cellulose, wool, silk, polyester, polyamide, polyacrylonitrile, polyvinyl chloride, glass or asbestos.  The polycondensation products may be those described in Specifications 1,002,325, 1,013,828 (See also Division C3).  Examples are given and Specifications 828,052,851,976 also are referred to.

Title: Vacuum proving apparatus for plant using gaseous fuel and  plant having such arrangement
IPC: G01M3/34
Filed: 1972-05-05
Abstract: 1426556 Burner control BRITISH GAS CORP 12 April 1973 [5 May 1972] 20928/72 Heading F4T [Also in Division G1] To leak test a section of pipe (not shown) in plant such as a burner using gaseous fuel, an electrical system including a timer, a differential pressure-responsive switch 10 and a vacuum pump 14 are provided, the section to be tested being isolated then pumped out to a reduced pressure whereupon if the reduced pressure is maintained for a predetermined time, the switch gives a positive output signal but if the pressure rises during this time the switch acts to indicate that the section has a leak. When power is supplied on lines 18 and 20, timer motor 38 starts and cam switches C1-C5 begin to rotate. Switch C1 first closes and energizes a solenoid 12, to close a vent valve in the pipe section, and a relay R1 thereby closing contacts R1<SP>1</SP>, to keep relay R1 energized when switch C1 subsequently reopens, and opening contacts R1<SP>11</SP>. Switch C2 then closes and energizes the pump 14 and control valve solenoid 16 to start evacuation of the pipe section until at a predetermined low pressure switch 10 operates to connect terminals 32 and 36 thus de-energizing pump 14 and solenoid 16. A predetermined proving time now elapses. If the terminals 32 and 36 are still connected at the end of this time indicating that the reduced pressure has been maintained in the pipe section, when switches C4 and C5 are closed, a lamp 28 is lit and a device 30 and relay R2 are energized. The device 30 may automatically initiate ignition of the burner. Relay contacts R2<SP>11</SP> are opened, and contacts R2<SP>1</SP>, R2<SP>111</SP> closed to maintain relay R2 energized. Timer motor 38 continues to run until switch C3 operates to end the test cycle. However if at the end of the proving time the pressure in the pipe section has risen; switch 10 will have reverted to reconnect terminals 32 and 34 and so when switch C5 closes, relay R3 is energized and contacts R3<SP>1</SP> closed to light a lamp 24 and actuate an alarm 26, contacts R3<SP>11</SP> being opened to isolate the remainder of the system, the de-energization of solenoid 12 venting the pipe section to atmosphere. The system then must be manually reset to override the lockout.

The spring is compressed between faces 50 and 41 as the nut moves up when the valve seats and between faces 53 and 46 as the nut moves down when the valve reaches its open position to prevent excessive pressure on the valve gate. An indicator 66 determines the thrust in the valve stem and a lubricant passage is formed at 60, 62, 65. U.S.A. Specification 2,878,687 is referred to.

Title: Molecular vacuum pump
IPC: F04D19/04
Filed: 1963-05-27
Abstract: 1,015,887. Molecular vacuum pumps. W. K. ROBERTS. May 27, 1964 [May 27, 1963], No. 21018/63. Heading F1C. In a molecular vacuum pump of the type in which a rotor disc co-operates with spiral stator grooves at each side of the disc, the gases or vapours being pumped from the centre of the rotor to the periphery on one side of the rotor and then from the periphery to the centre on the other side, two or more such discs are arranged to pump in series. The stator grooves may decrease in cross-sectional area from inlet to outlet. To prevent contamination of the vacuum by oil vapour given off from the bearings, the rotor discs may be carried by a stub shaft journalled in bearings at the end adjacent the exhaust side of the pump. To reduce the forces on the bearings, the rotor discs may be made progressively smaller in diameter in accordance with their distance from the bearings. The shaft may instead have a bearing at each end, in which case the bearing at the end adjacent the vacuum may be of a type not producing contamination of the vacuum, such as a magnetic bearing. Where both bearings are of ordinary type, however, the vacuum inlet may be located midway between the bearings, the rotor discs being arranged in two sets of series-connected discs, the sets pumping from the common central inlet towards respective exhaust connections at opposite ends of the shaft. In a modification, one set only may have an exhaust connection, the other set (which may comprise a single rotor disc) acting merely to prevent ingress of oil vapour from the adjacent bearing into the vacuum inlet.
