Filed: 1954-12-04
Abstract: 815,899. Heat treatment furnaces. DOWSON & MASON Ltd., [formerly DOWSON & MASON GAS PLANT CO. Ltd.], and LEONARD, L. G. A. Dec. 5, 1955 [Dec. 4, 1954], No. 35169/54. Class 51 (2). A heat-treatment furnace intended particularly for boilers and other pressure vessels 22 comprises standard wall elements 10 fabricated from sheet steel or the like and enclosing heat insulating material 11, e.g. mineral wool, the said elements having co-operating convex and concave upper and lower walls 15 and 16 and being suspended by hooks 17 from rails 20 on metal piers 24 and girder units 30, 31 or 32. The piers are built up of angle or channel-section members suitably cross-braced to form double girders with vertical outer chords and inclined inner chords, and are disposed opposite one another at the junctions of prefabricated elements 18 forming the furnace hearth. A 30 degrees bevel on the edges of the outer elements 18 supports the lowermost wall elements 10 which each have one co-operating flat side. Each pier 24 has a vertical web 28 bolted to a counterpart 29 on a girder unit 30,'and polygonal furnaces of various sizes can be erected by using one or more further girder units 31, 32. Asbestos or like packing may be introduced into the joints between different courses of the wall elements 10. Joints between the wall elements in each course are each provided with a packing comprising a T-section metallic member 33, Fig. 7, packed with mineral wool 34, and having spaced lugs 35 projecting through slots in an external cover-plate 36 which is held by cotters 37 driven through slots in the lugs. At least one end wall of the furnace is similarly built up of wall elements 10, Fig. 1. The furnace is heated by gas or liquid-fuel burners 29 directed into combustion chambers 40 disposed in staggered relationship on opposite sides of the hearth. Annular spaces 43 supplied with air from mains 41 and fans 42 surround the combustion chambers, and a mixture of combustion gases and heated air is supplied to the furnace through fish-tail outlets 44 disposed near the hearth just short of its centre line. The hot gases are thus directed substantially tangentially of the boiler 22, and are vented through one or more offtakes 45 in the end wall. Part of the waste gases may be recirculated to the combustion chambers, and additional diluent air may also be added. The boiler 22 is carried by pairs of spaced supports 21 comprising arcuate cradles centrally pivoted on a pedestal 23. Specification 616,166 is referred to.

Title: Improvements relating to storage devices
Inventor: SIVYER RAYMOND FRANK
IPC: G11C7/02
Filed: 1964-08-29
Abstract: 1,113,881. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. 13 Aug., 1965 [29 Aug., 1964], No. 35470/64. Heading H3B. [Also in Division H1] The mutual coupling between the sense and digit conductors, S and D, associated with a pair of columns in adjacent planes of data storage elements, e.g. thin magnetic films E, is reduced by reversing the coupling between conductors in one column relative to the coupling in the other column, and cancelling the residual coupling by providing conductor portions between which a capacitive coupling of the required magnitude and sense exists. In Fig. 1 the storage elements are mounted on a substrate between printed circuit supports 1a, 16. The outward and return portions D1, D2 of the digit conductors each consist of two parallel conductors interconnected at the ends of the planes, with the sense conductor outward and return portions S1, S2 lying between these parallel conductors. Supports la, 1b respectively have the conductors printed on their lower and upper surfaces. A board 3a, having conductors on both surfaces, is sandwiched between the ends of supports 1a, 1 and the corresponding conductors are soldered together through slots in the supports. At the free end of board 3a the conductors are arranged as shown so that they can be vertically aligned with corresponding conductors in an adjacent plane. The vertically corresponding conductors of the two planes are soldered together so that digit conductor D1, which passes above the storage elements in the upper plane, is connected to D3 which passes above the elements in the lower plane, whereas sense conductor S2, above the elements of the upper plane, is connected to S4, which passes below its associated elements. As a result part of the mutual coupling between the sets of conductors is cancelled out. The conductors on board 3a are also extended to a board 3b and brought into vertically aligned pairs to form capacitors. Due to the crossing of the conductors capacitively induced signals on board 3b are opposed to those on the corresponding board 4b of the adjacent plane. These capacitances are adjusted by cutting portions of one board or the other to leave a capacitively induced noise component which is equal and opposite to the residual inductively induced noise. One of the boards 3b, 4b may be removed completely and the other board trimmed; or one only of the capacitances on a board may be adjusted; or only one capacitance may be provided on each board. The capacitive coupling arrangement may be provided for each pair of planes in the store, or fewer may be required.

Title: Improvements in or relating to valve actuators
Inventor: FRY JEREMY JOSEPH
IPC: F16K31/05
Filed: 1957-11-14
Abstract: 842,581. Control of motors. ROTORK ENGINEERING CO Ltd. Sept. 15, 1958 [Nov. 14, 1957], No. 35537/57. Class 38 (3). [Also in Groups XXIV and XXIX] A reversible electric motor 10 can be connected through a dog clutch 20, 26 to a shaft 3 carrying a worm 65 meshing a worm gear 4 driving the spindle 1 of a valve, the worm 65 being splined for axial movement upon the shaft 3 and biased leftwards of the Figure by a stack of Belleville springs 77. A pin 81 on a lever 78 engages a groove 82 on the worm 65, the lever 78 actuating a switch 80 controlling the motor. When the spindle 1 stops turning on closure of the valve, the worm 65 tends to slide axially along the shaft 3 and, through the lever 78, actuates the switch 80 to stop the motor. In the valve-opening direction, the motor 10 is controlled by a worm 5 driving through a worm gear 84 to a shaft 85, in turn driving through a variable-ratio device 87 (not further described) to a second switch 86 arranged to stop the motor when the valve has been sufficiently opened. As a modification, the worm 65 may be arranged with a stack of Belleville springs 77 at either end, so that it can slide either left or right of the Figure and accordingly operate the switch 80 when the spindle 1 ceases to rotate on completion of both the valve opening and the valve closing movements.

IPC: A44B11/25
Filed: 1969-07-16
Abstract: 1,205,916. Safety harness buckles. F. G. HUGHES. ,16 July, 1969 [24 July, 196S], No. 35744/69. Heading E2A. A buckle assembly for seat safety harness includes strap tongue plates 16, 18 having portions thereof intercoupling the plates, the plates being positioned adjacent each other, a buckle having a frame formed with an opening therein for receiving the plates in juxtaposed relationship to be intercoupled by the intercoupling portions, and latch means mounted in the frame and releasably engaging one of the plates to retain .both plates in the frame, As shown, the buckle assembly 20 includes upper and lower connected frames 22, 24 and a pivoted latch member 26 having a protruding part 26a and biassed in an anticlockwise direction by a spring 28 such movement being limited by an operating memher 30 moved by a spring 33 in a clockwise direction and in the opposite direction by depression of a push button 34. Insertion of the tongue 18 attached to a lap safety belt 14 causes an opening in the tongue to 'be engaged by the part 26a of the latch 26 and subsequent insertion of the tongue 16 attached to a shoulder safety belt 12 turns a lock bar 54 against the bias of a spring when the boss 16a of the tongue engages in the opening 18a of the tongue 18, the lock bar being moved back to the position shown in the figure. Operation of the push button 34, pivots the member 30 to depress the latch 26 when the tongues may be removed from the buckle. The tongue may have a degree of lateral angular movement. The arrangement is such that false latching is prevented by insertion of the tongue 18 prior to the tongue 16. In a modification, the boss 16a is replaced by a spring-loaded latch engageable in a opening in the tongue 18.

Title: Improvements in brake mechanism for vehicles
IPC: B60T1/06
Filed: 1920-12-30
Abstract: 156,588. Stringer, M., Bauder, G. T., and Merkel, A. E. Jan. 9, 1920, [Convention date.]. Brakes, arrangement and disposition of; flexible transrmitters.-Relates to brake mechanism particularly for motor vehicles in which each brake drum is provided with two brake bands or equivalent. Instead of the arrangement in which there are two actuating levers each connected to two bands one associated with each drum, each lever is adapted to actuate all the bands through equalizing connections. As shown in Figs. 1 and 6, each drum 11 has a pair of expanding bands 28, the members of each pair being actuated resspectively by a tubular shaft 12 and a shaft 13 disposed therein. Arms 14, 15 on the shafts 12, 13 are connected by links 16, 17 to an equalizing plate 10. A pair of cables 8 each extends between the plates 10 and passes over pulleys 3, 6 on a cross-member 2. The cable 8 passes also over a pulley 20 on a rod 21 adjustable in length connected to the pedal lever 22 and the cable 9 similarly is connected to the emergency handlever 26 by the rod 25. When either lever 22, 26 is actuated, the four brake bands are applied to the respective drums 11 and with equal pressure on all the bands. Fig. 10 shows each drum 11 provided with an internal and an external band connected to the plate 10 respectively by lever 35 and link 16 and by link 17 and the lever system 36 including the arm 37. If it is desired with this arrangement that the links 16, 17 be equal and interchangeable, the plate 10 may be modified as shown in Fig. 12. The cross-member 2 may be adjustable for various widths the frame 'by constructing it of two channel-section members 29, 30 cut out as at 31, 31a and having a filler block 32 disposed between them. The parts are secured together by the bolt 33 which passes through the strap 5 on which the pulleys 6 are mounted.
