Title: Improvements in or relating to the manufacture of cement, lime and the like, and kilns therefor
IPC: C04B2/10
Filed: 1925-08-07
Abstract: 260,684. Girouard, Sir E. P. C. Aug. 7, 1925. Shaft kilns.-A kiln in which powdered cement making materials are showered down a substantially vertical shaft against an ascending stream of hot gases is formed by sinking the shaft in the ground. As shown, the shaft A is sunk near the face B of a quarry, its lower end being at the level of the floor B<2>. The lower sintering portion of the shaft is reduced in cross sectional area relatively to the remainder by a lining E and the top E<1> may also be lined or built up of brickwork. The stream of hot gases is produced by burning pulverized fuel, supplied through nozzles C, with air, which may be heated in a pipe L<1> passing through a cooling-chamber K formed as a downward extension of the shaft. Grouped around or in line with the shaft A may be other shafts for the storage and drying of the raw materials, and storage of the clinker, and in connection with these shafts are suitable conveyers and elevators for handling the materials. The waste heat of the process may be used for the low temperature distillation of fuel, either by fitting an annular retort S at the upper end of the shaft, or by showeting down powdered fuel through a part of the length of the shaft. The fuel is caught by a baffle, beneath which the cement making materials are introduced. The gas and coke produced may be used for firing the kiln, and the waste gases are passed through a dust extractor P and a waste heat boiler Q. When the shaft A is sunk in, the whole or part. of it may be burnt out so that the baked wall of the shaft itself forms a refractory lining.

Title: Improvements relating to joints for spectacles
IPC: G02C5/22
Filed: 1931-07-10
Abstract: 381,604. Spectacles. WINGATE, G. H., 15, Wigmore Street, London. July 10, 1931, No. 19893 and 22615. [Class 97 (i).] A spectacle joint for the attachment of the sides to the eyes is provided with a spring serving to urge the sides slightly inward from their extreme open position so that they grip lightly upon the wearer, and also serving to exert pressure between the pivoted parts in other positions so that the joint remains reasonably tight. In Fig. 1, the joint comprises a plate 7 fixed to the frame 2 and cut away between a pair of cheniers to which is pivoted a chenier 8 on the side 3 so that the chenier 8 projects through the plate and engages a spring 9. The chenier 8 is cut away as at 8a or is otherwise formed so that pressure on its edge when in the fully open position tends to push the side slightly inwards. A second recess &c. 8b may be provided to enable the side -to be held by the spring when in the closed position. In Fig. 6 the spring 14 has a pin 13 which exerts pressure outside the pivot against the end of the opened side in a direction transverse to the plane containing the lenses. In another form the spring is retained at its fixed end between the plate 7 and a shoulder formed on one of the pins by which the plate is secured to the frame. In a further form the spring is contained in a fork which embraces, and is secured to, the side 3.

Patent GB-750168-A (GB)
Title: Improvements relating to photo-electric guard arrangements
Inventor: SHERLOCK JAMES
IPC: F16P3/14
Filed: 1953-07-17
Abstract: 750,168. Photo-electric guard arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 23, 1954 [July 17, 1953], No. 19937/53. Class 40 (3). A photo-electric guard arrangement comprises means directing a light beam on to a mirror of parabolic section or a converging lens through its focus and angularly rotating it about the focus to give a projected beam parallel to the optical axis sweeping transversely to the axis to define a protected area, and a similar mirror or lens with its axis parallel to said optical axis to receive the beam and focus it on the photosensitive surface of a photo-electric device forming part of a circuit responsive to changes in its output. In Fig. 1A a series of rotating beams which successively traverse mirror 3 to give a parallel scanning beam 6 is formed by the rotating slotted cylinder 2, the spacing of the slots 4 being such that just before one beam leaves one end of the mirror the following one illuminates the other end. The mirror is a section of a paraboloid bounded by two parallel planes which are parallel to but off its axis so that the source 1 and cylinder 2 do not form a shadow in the swept area. The scanning beam is reflected by a corresponding part of a second paraboloidal mirror 7 on to a photo-cell 8 in the grid circuit of one V1 of a pair of cathode coupled valves V1, V2. A trip circuit which when broken operates an alarm or brings into operation some safety measure includes the normally closed contact RL1<SP>1</SP> of relay RL<SP>1</SP> and RL1 of relay RL. When the illumination of photo-cell 8 is cut off by an object in the protected area, the current through V2 falls and a positive pulse is delivered to the grid of V3 which forms with V4 a flip-flop circuit. V4 is normally conductive and V3 cut off, but on receiving the pulse V3 conducts and V4 is cutoff and remains cut off for a time determined by the charging time of capacitor C. This time exceeds the interval between two successive scannings of any part of the protected area so that further positive pulses arrive at the grid of V3 before V4 recommences conducting. So long, therefore, as the object remains V4 is cut off and relay RL is de-energized to open the trip circuit. Relay RL<SP>1</SP> is responsive to the mean anode current of V2 and remains energized with its contacts closed unless the average illumination of the cell falls below a certain level due to light source failure, or when a large object blocks the beam for an appreciable part of the scanning cycle, in which case it releases to open the trip circuit. In a modification, a single beam is angularly oscillated to scan the surface of the first mirror alternately in opposite directions. Parabolic mirrors or converging lenses may be used instead of the paraboloidal mirrors. Specification 715,444 is referred to.

Title: Stand of fire buckets
IPC: A62C8/00
Filed: 1922-07-20
Abstract: 203,135. Hodgson, H. E. July 20, 1922. Hand sprinklers for liquids.-Buckets adapted to be superposed to form a stand have their bottoms and tops so formed that the top of one bucket receives and supports the bottom of the bucket above, which acts as a cover. The buckets 1 are formed at the top with a laterally offset rim 2 forming a shoulder 3 to support the bottom of the bucket above, the top bucket of the stand having a cover 4. Each bucket has a filling-opening with screw plug in its side near the top. The bottom bucket stands in a cup or ring 10 fixed to a floor or deck. The stand of buckets is provided with a rigid vertical support, such as a post 11 engaging central funnels or tubes 12 in the buckets 1. In a modification, the vertical support consists of an external cage, which also serves as a means for lifting and carrying the stack of buckets.

Title: Improvements in gas dispensing systems
Inventor: BILLINGTON EVANS R
IPC: F17C13/04
Filed: 1955-07-11
Abstract: 811,915. Valves. BASTIAN-BLESSING CO. .July 11, 1955, No. 20004/55. Class 135. [Also in Group XIX] Means for controlling the delivery pressure of gas stored in the liquefied state in a pair of bottles and arranged so that the delivery is normally from one bottle but a change over to the other bottle is effected upon depletion of the contents of the first bottle comprises a first stage regulator for each bottle, a second stage regulator common to both bottles, and indicator means to show whether the supply is being drawn from the first or the second of the bottles. The first stage regulators comprise a common diaphragm 40, Figs. 3, 4, engaging the stems 34 of valves 33 which open against the direction of flow of gas from pipes 3 which are connected to the bottles. Loading springs 55 act on the diaphragm 40 adjacent the valve stems and are adjustable by a shaft 47 with eccentric portions 48. The chamber 23 below the diaphragm 40 is connected through the second stage pressure regulator with a discharge passage 24, the second stage regulator consisting of a valve closure member 76 coacting with a seat 71 and movable through a bell-crank lever 80 by a flexible diaphragm 82 loaded by a spring 94 which opposes the delivery pressure acting on the diaphragm. Any excessive pressure in the outlet 24, after closing the valve member 76, causes further movement of the diaphragm 82 to the left away from an abutment 87 to permit escape of gas through a vent 97. When the shaft 47 is in the position shown in Fig. 4 the spring 55 of the left-hand valve is compressed to a greater extent than that of the right-hand valve so that the supply of gas will be taken from the bottle connected to the left-hand valve until the pressure falls to the value determined by the compression of the spring of the righthand valve whereupon the supply is taken from the other bottle. The bottle connected to the left-hand valve may then be exchanged for a fully charged one and the shaft 47 turned through 180 degrees so that the right-hand spring 55 is compressed more than the left-hand spring and the supply will continue to be drawn from the bottle connected to the right-hand valve until it is exhausted whereupon a further changeover will be effected. A handle on the shaft 47 is marked to indicate which of the bottles is connected to the regulator that is set for the higher pressure. When one of the bottles becomes exhausted its associated valve will move to its lowest extent and cause an indicator 62 to appear behind a window to warn the user. In addition, the drop in delivery pressure of the first stage regulator when a changeover is effected from one bottle to another is communicated through a conduit 105 to a remote indicator as described in Specification 811,916, [Group XIX].

Title: Improvements relating to on-load tap-changing circuits
Inventor: APPLEYARD ALFRED NOEL
IPC: H01F29/04
Filed: 1953-07-20
Abstract: 761,983. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. July 20, 1954 [July 20, 1953], No. 20054/53. Class 38 (2). On load tap-changing equipment comprising sequentially operated diverter switches D1, D2 associated with bridging reactors or resistors, is so connected to the tapped transformer winding that a winding or part A of a winding linked with the main flux of turns value less than (preferably half) that of the winding part between adjacent taps, is alternately inserted in and removed from the circuit while the transformer ratio is progressively increased or decreased during the tap-changing process. The first five diagrams of Fig. 4 ((Part), show the sequence of operation of the diverter switches in the position in which both selector switches S1, S2 are on the lowest tap and the winding A is cut out, while the next diagram shows the first step of the sequence in which the selector switches are moved to the next main tap and the winding A is re-inserted. By this arrangement the number of leads for a given number of ratio change positions is reduced. Various other ways of connecting the winding A in the circuit are described, and the invention may be applied to autotransformers.

Title: Improvements in or relating to braking systems of articulated vehicles
IPC: B60T13/58
Filed: 1967-05-02
Abstract: 1,136,876. Braking systems for vehicles. SOC. ANON. ANDRE CITROEN. 2 May, 1967 [9 May, 1966], No. 20252/67. Heading F2F. A braking system for articulated vehicles comprises three separate fluid-pressure systems for the tractor front brakes, tractor rear brakes and trailer or semi-trailer brakes respectively, the apportioning of the braking effort between the front and rear brakes of the tractor being varied by a compensating bar and roller in accordance with the load on the rear axle. In the figure an hydraulic system with main reservoir 5 controls the tractor brakes 26, 29, and a pneumatic pressure system with reservoirs 59, 61 controls the trailer brakes 69. If the trailer is not coupled, the load on the tractor rear axle 39 will be light, and linkage 41-49 moves a roller 38 to the left (as shown). Depression of the brake pedal 37 then causes the first slide valve 21 to move downwards to connect lines 16 and 25. Pressure in reservoirs 9 and 11 is then communicated to the front brakes 26 and via line 25a to an auxiliary piston 27 on the rear brakes, producing a full application of the front brakes and a partial application of the rear brakes. If the rear axle 39 is loaded, e.g. if a trailer is connected, the linkage 41-49 moves the roller 38 to the right. Depression of the brake pedal 37 then moves a second slide valve 32 downwards to connect lines 18 and 53. Pressure in reservoir 14 is then communicated via line 53 to an hydraulic actuator 54 which opens an air valve 55 in the trailer braking system allowing compressed air from reservoir 58 to actuate the trailer brakes 69. Subsequently, the first slide valve 21 operates as before to actuate the tractor brakes. A third slide valve 33 in the same bore as the second is separated from it by a chamber 40 which communicates with line 53. When the pressure in this chamber rises sufficiently, valve 33 moves downwards to connect lines 17 and 72 and allow pressure in reservoirs 12 and 13 to be communicated to a main piston 73, thus producing a full actuation of the tractor rear brakes. Modifications.-The trailer braking system may be vacuum instead of pressure, operated from a vacuum pump or engine induction pipe. The tractor braking system may also be pneumatic. The brakes may be drum or disc. The auxiliary piston 27 on the tractor rear brakes may be omitted. The valves 32 and 33 may be in separate bores.
