Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1942-04-15
Abstract: 550,796. Valves. AKTIEBOLAGET ELEKTROLUX. April 15, 1942, No. 4945. Convention date, April 22, 1941. [Class 135] [Also in Group XIII] In a continuous cycle inert gas absorption refrigerating system, re rigerant condensate formed under abnormal conditions, paricularly high temperatures of the cooling-air for the condenser 17, is utilized for building up liquid columns in the apparatus to produce pressure differences in the gas spaces and thereby control the operation of the system. Vapour evolved in the generator 10 passes through a vessel 13, and rectifier 14 to the condenser, whence liquid refrigerant flows through a seal 15 to the upper portion of a part 18 of the evaporator. The condenser communicates by conduit 21 with the lower part of a " pressure" vessel 20 normally filled with inert gas (hydrogen). Any vapour not condensed in the condenser passes into the pressure vessel, which is air cooled and displaces hydrogen until the partial vapour pressure increases sufficiently to condense the vapour, the condensate flowing through a seal 24 into a vessel 25 and thence by conduit 27 to an upper portion 28 of the evaporator. The increased pressure forces down the liquid level in the vessel 13 and raises the level in valve chambers 31 ... 34 connected thereto. The gas spaces of these chambers are connected to one another, to the evaporator, and to the gas heat exchanger 35 by the several conduits shown, and the chambers 31, 33 are fitted with float valves opening upon rise of liquid level, while the chambers 32, 34 provide liquid seals closing the respective conduits on rise of level. In normal operation the weak inert gas flows through the left limb of U tube 38 to the top of the evaporator and thence downwards in the same direction as the refrigerant and through the valve chamber 32 to the gas heat exchanger. With the rise in liquid lever in the valve chambers the weak gas flows through valve 31, and U-pipe 36 to the bottom of the evaporator, and thence upwards in counterflow to refrigerant, the rich gas passing down the right limb of U-tube 38 and through valve 33 to the gas heat exchanger. The float valve may comprise a wood member 62, Fig. 2, in a cylinder 61 loosely fitting around a flanged part of the conduit 36. The cylinder may have a drain hole 63 and its movement may be limited by pegs 64 in the wood member.

Title: Improvements in or relating to ventilation apparatus
IPC: F24F8/108
Filed: 1962-02-08
Abstract: 923,673. Ventilators. O. H. DRAGER, [trading as DRAGERWERK H. & B. DRAGER]. Feb. 8, 1962 [Feb. 8, 1961], No. 4975/62. Class 137. One or more short pipes, each with a filter device releasably connected to its end, extend through a wall blocking a ventilation duct, and shut-off means prevents flow through the or each short pipe when the filter device is disconnected from the pipe end. As shown, Fig. 1, air flowing in a ventilation duct 1 is blocked by a solid wall 4, and by walls 5 and. 6 of zig-zag form having apertures 11 fitted with short pipes 12 to the outlet ends of which are attached filter boxes 13 and 14 (18 in Fig. 2). The filters 13 on wall 5 are coarse filters, while the filters 14 on wall 6 are fine filters. The filter boxes are supported by a framework 20, Fig. 2, and a short inlet pipe 17 on each box fits into a rubber sealing ring 16 on the end of the appropriate pipe 12. A butterfly valve 23 in each pipe 12 is pivoted horizontally and has an external lever 25 which latches into an eyepiece 26 on the filter box when in the open position. When the filter box is to be removed, the lever 25 must be unlatched, and it is then latched into a second eye-piece 27 to hold the valve closed. A closure cap 28 on the box may be torn off and used to close the inlet pipe 17 when the charged filter is removed.

Title: Improvements relating to safety harnesses
IPC: B60R22/415
Filed: 1959-02-12
Abstract: 940,263. Aircraft &c. safety harness. J. MARTIN. Feb. 12, 1960 [Feb. 12, 1959], No. 4993/59. Heading A3V. [Also in Division B8] A safety harness is restrained with respect to the seat by a strap 11 which is wound on a spring drum 9 on the seat back, passes between relatively movable clamping jaws 20, 21 in a unit 4 at shoulder level, then through a yoke 15 on the harness and is finally secured to an apertured lug 12 releasably retained in a slot 18 in the seat by a locking bolt 13. The upper jaw 21 is normally held in cocked position to allow for movement of the strap 11 in either direction, but when the seat or occupant is subjected to a sudden change in velocity, inertia operated means pivot the jaw 21 towards the fixed jaw 20 so as to grip the strap 11. The jaw 21 is mounted on a shaft 22 to one end of which is secured a crank arm 24 which is pivoted at its other end 27 to an axially telescopic spring-loaded link 25 having its other end pivotably anchored at 26 to the side of the unit 4. Under normal conditions the pivot 27 lies above a line 28 through the pivot 26 and shaft 22 so that the spring in the link 25 retains the jaw 21 in a cocked position; on a sudden change in velocity the jaw 21 is pivoted downwardly due to the inertia of its own mass 23 so that the pivot 27 lies below the line 28 and the spring helps to snap the jaw into its clamping position. In a modification the inertia mass 23 is separate from the jaw 21 and located on a separate lever operating the jaw. A manual control lever for locking or releasing the strap 11 may be mounted on the seat pan and may operate the shaft 22 through linkage and telescopic torque mechanism (Fig. 11, not shown). Specifications 848,208 and 854,769 are referred to.

Title: Improvements in tape transport apparatus
Inventor: FORMBY JOHN ALBERT
IPC: G06K13/26
Filed: 1955-09-23
Abstract: 819,628. Automatic control systems. FORMBY & CO. Ltd., J. Sept. 23, 1955, No. 5007/58. Class 38 (4). In a tape-transport apparatus the catenary formed by an opaque tape suspended between a supply spool and a driving means is detected by two beams of light which influence photoelectrically-operated switch means controlling an electromagnetic clutch in the spool drive so as to maintain the catenary between limits defined by the two beams of light. When a sprocket 27, rotating clockwise, feeds data tape past an erase head 59 and a recording or repro ducing head 26, the catenary formed by the tape at the left-hand side of the sprocket is shortened until a beam of light from a source 53 falls on a photo-cell 55. The response of the photo-cell fires a thyratron 57 and current through the latter operates a clutch 47 to cause the supply spool 45 to be driven against the resistance of a light brake 58. When the lower tip of the catenary obscures the beam of light from a source 52 the response of a second photo-cell 54 fires a thyratron 56 which quenches the thyratron 57 and so disengages the spool drive. Similarly, a take-up spool is started when the right-hand catenary obscures the beam from source 52 to a photo-cell 54a, and is stopped when a photo-cell 55a responds to light from the source 53. Specification 817,321, [Group XXXVIII], is referred to.

Title: A method for carrying out heating processes in long kilns and a long kiln for carrying out the method
IPC: F27B9/30
Filed: 1968-02-01
Abstract: 1,218,982. Tunnel kilns. SVENSKA METALLVERKENS UGNS A.B. 1 Feb., 1968 [3 Feb., 1967], No. 5113/68. Heading F4B. A method of heat treating ceramic goods in tunnel kilns having pre-heating 11, burning 12 and cooling 13 sections, is characterized in that a part of the kiln space is divided in its longitudinal direction into relatively long sections separated by relatively short sections by controlling the removal and supply of gas from and to said part of the kiln space, a counterdirectional flow of gas being maintained in adjacent relatively long sections in said part of the kiln space, the gas removed from at least one of the relatively long sections being passed through a circulation system wherein the gas is modified with respect to its temperature and/or composition. As shown, the cooling section 13 is divided into relatively long and short sections. In operation, gases from a final cooling zone 18 are conveyed by means of a fan 17 in a conduit 19 to the rear of section 10 to dry the bricks, the 'after-dried' bricks entering the preheating section 11 in counterflow to hot gases comprising hot air and products of combustion, these gases arriving from two recirculation zones 21, 22 situated in the cooling section 13 via conduit 23, and also from the firing section 12 situated behind the section 11. The bricks after passing through the firing section 12 enter the cooling section 13, said section 13 being subdivided into three zones, the relatively long recirculation zones 21, 22 and the final cooling zone 18, said zones forming three separate gas flow zones. In the zones 21, 22 newly supplied cooling gas is introduced via conduits 36, 47, respectively, a gas flow corresponding to the newly supplied gas flow being led away from the recirculation system through conduits 38, 49, respectively, into the conduit 23. Arranged in the conduits leading to the various sections are valves, e.g. 26, by which the pressure drop in the sections can be controlled. This control is suitably effected automatically on receipt of a signal sent from means, e.g. 27, which senses the pressure at some suitable portion of the associated section.

Abstract: 1,043,401. Ventilators. H. H. ROBERTSON CO. Feb. 10, 1964 [Feb. 9, 1963], No. 5360/63. Heading F4V. Control means for a ventilator having simultaneously pivotable louvres 11 comprises independently operable lineally opposed power cylinders having pistons 14 and 15 one of which is connected at 18 to the ventilator frame 10 and the other of which is connected to a lever 12 by means of which the louvres are operated. As illustrated, a partition 25 divides a cylinder 13 into two single-acting cylinders. A spring 21 biases the louvres to the closed position and a fusible link 20 is included in the connection between the piston 15 and frame 10. When both pistons are at the limit of their outward movement the ventilator is fully closed and vice versa. The cylinders are connected by lines 23 and 24 to manual control valves, Fig. 3 (not shown), which connect either or both cylinders to a compressed air supply or to atmosphere. The stroke of the piston 15 is twice that of the piston 14 so that two positions of the louvres may be obtained between fully open and fully closed. A plurality of ventilators may be connected to the valves to operate in unison. In a modification, Fig. 2 (not shown), the louvres are spring-biased to the open position and the cylinders arranged so that the ventilator is closed when the pistons are fully retracted and vice versa. In another modification, Fig. 4 (not shown), the spring bias is omitted and doubleacting power cylinders are used to open and close the ventilator. The ventilator may include means for removing foreign matter and water and the control valves may be thermostatically operated.

Abstract: 773,593. Thermally-actuated valves. BRITISH THERMOSTAT CO., Ltd. Feb. 18, 1955 [Feb. 24, 1954], No. 5475/54. Class 135. A gas supply valve is provided with latching means to lock a rotary plug cock 1 in its closed or open position and a common manual member 16 for turning the cock between these positions but capable of disengagement in the fullyopened position of the latching means for independent operation to vary the temperature setting of a thermal statically controlled gas valve 5. A slotted arm 24 attached to the plug cock is locked in its closed position by engaging between a lug and a boss on a locking plate 25. On depressing the member 16 against a spring 28 the plate 25 is moved downwards and a pin 23 engages in the arm slot 24 so that the rotation of the member 16 turns the cock to its open position whereupon release of the member 16 allows the plate to lock the arm against another lug and at the same time lifts the pin out of the slot. Further rotation of the member 16 engages the bent spindle 14 and rotates the screw 15 so that the thermostatic valve seat 6, sealed to the casing by bellows 30, moves up under the spring 29. Temperature variation of the bulb 9 moves the bellows 7 to vary the position of the valve 5 with respect to its seat 6, an overload spring 36 being provided between the bellows and the valve. To compensate for local temperature variations a bi-metal disc may form the connection between the bellows 7 and the valve stem 33. A pin on member 16 engages axially displaced connected slots 18 in the casing spigot 17 to limit rotation of the member 16. The spindle 13 is initially set by a screw 34 and resilient bush 35.
