Title: Improvements in and relating to air conditioning apparatus
Inventor: HALL SYDNEY
IPC: F24F6/06
Filed: 1956-09-12
Abstract: 831,495. Humidifying air. HALL & KAY Ltd. Sept. 27, 1957 [Sept. 12, 1956], No. 27830/56. Class 55 (2). Air conditioning apparatus comprises a plurality of ejection nozzles 20, Fig. 2, carried by a rotatable mounting 9 and supplied with compressed-air through pipes 19 so that the mounting is rotated under the action of the compressed-air issuing from the nozzles, and water is raised from a container 7 and ejected from the nozzles under the steam injector principle. A pipe 14 has suitable attachments by which the apparatus is suspended and water passes through the pipe 14 and cranked end 17 into the container 7 under the control of a valve operated by float 18. A hollow spindle 10, Fig. 5, blocked at both ends 15, 16 surrounds part of the pipe 14 and is fixed at its upper end to block 11, whilst its lower end has bearings to enable block 9, pipes 13, container 7 and cover 8, to rotate around it. The compressed-air entering pipes 19 passes through the space between pipe 14 and spindle 10 to the pipes 13 and nozzles 20, thus causing water from container 7 to pass up pipes 21 to the nozzles 20. Openings 22 in the walls of container 7 are opposite the nozzles 20 which latter are turned off the radial position so that reaction from the nozzles causes the container 7 and cover 8 to rotate. The speed of rotation may be limited by providing a counterweighted bell-crank lever 24 (seen only in Fig. 5), on the cover 8, which co-operates with a plate 23 fixed to the block 11. In a modification, Fig. 6, a cranked lever 25 mounted on cover 8 and passing through an opening therein, has a ball 27 engaging the plate 23. Some of the nozzles may eject the spray radially and since this will not cause rotation, some of the pipes 21 are removed so that other nozzles only issue compressed-air and alone cause the rotation. Alternatively to assist rotation, vanes on the cover 8 are acted upon by compressed-air issuing from additional nozzles. According to the Provisional Specification, the container is of annular form supplied with liquid entering through one or more U-tubes from below, and the liquid passes through S- tubes to the nozzles which are also connected by tubes to a hollow portion of the spindle about which the container may rotate. Compressed-air is supplied from below to the spindle.

Well control, suitable for subaqueous wells, comprises a casing head 34 mounted on casing 30, a hanger 32 in the bowl 33 of the head and supporting casing 31, a hanger 60 in the bowl above the hanger 32 and supporting tubing 64, ducts 46 in the hanger 32, a passageway 54 in the head, and a valve 56 connected to the passage way and controlling flow from the annulus between the tubing and the casing 31. The flow from the tubing is controlled by a valve 71 and the flow from the annulus between the casings by a valve 59. In a modification, (Fig. 8, not shown) additional outlets from the tubing are controlled by valves 81 or may blacked by plugs engaging threads 84. The hangers have threads 44, 65 for engagement with threads on lifting pipes and the hanger 60 has threads 61A for the fitting of a plug. To prevent damage to the apparatus, during installation of the casing, a protector 88 (Fig. 17, not shown), is seated on the hanger 32 by a retriever 91 which is reversed on a pipe for removal of the protector. To prevent damage during drilling a protector extending over the greater part of the depth of the bowl is used.

Patent GB-286239-A (GB)
IPC: A61L2/07
Abstract: 286,239. Leseurre, A. March 1, 1927, [Convention date]. Drawings to Specification. Disinfecting.-A sterilizing process by humid heat in an autoclave consists in locating a compress soaked in water, alcohol, &c. in or adjacent the materials, the liquid being vaporized and expelling the air from the materials, so that a gas or vapour disinfectant can penetrate the materials. As applied to the disinfection of bedding, a wet cloth amongst the bedding is heated by steam with the autoclave open. The autoclave is then closed and the pressure increases until the temperature of the soaked compress reaches 110‹ C., when the autoclave is again opened and air is expelled from the material. Steam at 120‹ C., or other disinfecting gas is then passed into the material, or the compress may initially be soaked in formol. Surgical instruments and dressings can be sterilized by the above 'process by placing them in a box in the autoclave with the soaked compress located adjacent the materials.

Abstract: 1389022 Multiple-circuit hydraulic braking GIRLING Ltd 9 March 1972 [19 June 1971] 28844/71 Heading F2F In an hydraulic braking system of the kind in which hydraulic actuators of brakes on a front pair of wheels, and on at least one rear pair of wheels, on opposite sides of the vehicle, are supplied with hydraulic fluid under pressure from at least one master cylinder directly or indirectly pedal-operated, a total of at least three pressure spaces is defined within at least two master cylinders, and at least one brake on each wheel of each pair of wheels of the vehicle is adapted to be actuated by at least one hydraulic actuator, each pressure space being adapted to supply fluid under pressure to at least one pair of hydraulic actuators for applying a pair of brakes of which the brakes of that pair are each located on a different wheel of a pair of wheels on opposite sides of the vehicle. As shown, a first pressure space 18 defined between a positively-actuated main piston and a floating piston in a tandem master cylinder 17 is connected through line 28 with wheel cylinders 26 in a pair of front wheels 24, 25 having internal shce drum brakes. A second pressure space 19 defined between the floating piston and the closed end of the bore is connected through line 29 with wheel cylinder 27 associated with the same brakes in the same pair of front wheels 24, 25. A third pressure space provided in a single master cylinder 20 is connected through line 30 to wheel cylinders 31 (and optionally to wheel cylinders 33 in series therewith) for actuating shoe drum brakes on a pair of rear wheels 32. In operation, when pedal 22 is operated, all brakes are applied simultaneously. Upon failure of the space 21- line 30 circuit, only the front wheel brakes will be applied. Upon failure of either of the other circuits, the front wheel brakes can still be applied, but only by actuation of one wheel cylinder of each brake. In Fig. 2 (not shown), tandem master cylinder 17 is replaced by two single master cylinders and the upper end of balance beam 23, Fig. 1, in that case is connected to the centre of a further balance beam which connects the actuating rods of the above mentioned two single master cylinders. Each master cylinder may be actuated from an air booster. Preferably the front brakes are provided either with automatic adjusters or with signalling devices (associated with the master-cylinder actuating rod) to indicate availability of sufficient fluid in one circuit on failure of the other. Preferably a load-distributing valve between front and rear brakes is provided, and is set to operate just before a deceleration of 0À6 g is achieved, to produce an emergency stop of 0À3 g when the vehicle is fully laden. In a modification the 'front wheels' are in fact wheels on a tractor, and the 'rear wheels' are wheels on a trailer or semi-trailer.
