Title: Improvements in spraying apparatus or spraying heads for coating surfaces by spraying
Inventor: PIRIE WILLIAM JAMES
IPC: B41F23/06
Filed: 1950-07-19
Abstract: 688,405. Spray-producers. THYNE, Ltd., W. May 28, 1951 [July 19, 1950], No. 18010/50. Class 69 (iii). A spray nozzle ir which a granular, fibrous, flocculent, &c. material is sprayed by air pressure includes at the nozzle outlet an auxiliary air jet device rotatably mounted on the nozzle, the device having two diametrically opposed jet orifices which direct opposing air jets on to the emitted material to produce a fan-shaped spray. In a machine for spraying powder on printed sheets, compressed air is delivered to a pressure reducer 25, Figs. 1a and 2, through a line 24, and passes through a line 26 to a passage 28 in a spray head A, Fig. 3. This supply is continuous, and the passage 28 feeds pipes 21, 32, 33 leading to hollow collars 37, Figs. 6 and 7, arranged on the outlet end of powder delivery tubes 36. The collars include horns 38 with opposing outlets 41 through which air is directed to strike the powder stream. A second compressed air supply is led from the pressure reducer and passes through a line 42, an intermittently operated on-off valve E, a line 43, a passage 45 in the head A, and a line 47, Fig. 2, to a powder tank 20. This air agitates the powder in the tank, and the powder is drawn through lines 50, 51, 52 to the head A by injectors 58 surrounded by venturi tubes 55, 56, 57. The lines 50-52 are connected to the head at 53, Fig. 3, and are in communication with annular spaces 54, and when air passes from the passage 45 in the head to the injectors, powder is drawn into the tubes 55-57 and mixes with the air and is delivered through the tubes 21-23 to the tubes 36, Fig. 1. The pipes 31 and 33 are flexible, and the tubes 21 and 23 telescopic, and the tubes 36 are rotatably adjustable on the tubes 21-23. The valve E is cam-operated and is arranged to open, and hence effect spraying when a sheet is in position beneath the nozzles.

IPC: B64D13/00
Filed: 1956-06-11
Abstract: 831,742. Ventilating aircraft. ROLLSROYCE Ltd. May 31, 1957 [June 11, 1956], No. 18036/56. Class 137 Air supply means for a cabin 11 in a fast high flying aircraft comprises an annular ram air intake 13 which, during flight, supplies kinetically-heated air to a pair of rearwardly extending ducts 14 connected by elbows 15 to the air entry 16 of a unitary structure 12. An annular partition 17 divides the air entering the structure 12 into two oppositely and axially directed air streams, the forwardly directed air stream driving a main turbine 20 before being exhausted, through a control valve, to the atmosphere. The rearwardly directed air stream is delivered to a multistage compressor 25 which is connected by a shaft 21 to the main turbine 20 and delivers compressed air successively to a flow path 28a in a heat exchanger 28 and an expansion turbine 35 which is connected by a shaft 37 to the compressor 25 and passes air, at the correct temperature and pressure, through a duct 39 to the cabin 11. Vitiated air leaves the cabin through a duct 40 as a coolant to a flow path 28b in the heat exchanger 28, the air then being spilled overboard through a control valve. The annular partition 17 is positioned in the air entry 16 so that more air flows forwardly than rearwardly. Specification 821,544 is referred to.

Title: Improvements in and relating to electric lamps for use on board ship
IPC: B63B45/02
Filed: 1925-07-15
Abstract: 260,025. Woods, A. R. T. July 15, 1925. Retractive switches.-Electric lamps, particularly for illuminating ships' life-boats during launching, are hinged to the ships' structure so that when not in use they may be swung inwards into a protected position and at the same time automatically open the switch of the lighting circuit, e.g. by means of a projection a<4> on the lamp casing A engaging the lever or plunger of a weight or spring controlled switch E. The circuit-breaking may be effected by a part attached to the ships' frame or by an externally located switch operated by the pivotal action of the hinge bar. Reference has been directed by the Comptroller to Specifications 8253/05 and 143,248.
Patent GB-1347194-A (GB)
Title: Cordless electric garden trimmer with safety lock means
IPC: A01G3/06
Filed: 1972-04-19
Abstract: 1347194 Machinery guards J S DOYEL 19 April 1972 [15 Sept 1971] 18081/72 Heading F2J [Also in Division A1] A safety cover for the cutting unit of a hand held battery powered electric trimmer for grass, hedges or the like (see Division A1), is formed by a pair of spring biased shrouds which completely enclose the cutters when the trimmer is not in use. The actuating mechanism which opens the shrouds includes a switch so that the motor is only activated when the shrouds are open. In one embodiment, the shrouds 18 and 20 which also includes a funnel 21 for expelling trimmings are opened when triggers 34, 36 are pressed inwards against the force of a leaf spring 42 which normally biases the safety cover into the closed position. The stem 32 carries a switch so that the motor can only be activated when the safety shrouds open as the triggers are depressed. The shrouds 18, 20 are locked in the closed position by means of a plate 58 which is vertically slidable on a T-shaped projection 60 of the housing and which has outwardly extending jaws 58e, 58/ which clamp lugs 18a and 20a together. To provide a child tamperproof measure the plate 58 has to be pulled away from the housing to deflect the bar 60 before it can be pushed over a top ridge 62, prior to the opening of the shrouds. A groove 58b is provided in the back of the plate 58 so as to receive the ridge 62 and maintain the plate in the open position when the trimmer is in use. In an alternative embodiment, the funnel 21 in the shroud 20 (Figs. 7-11, not shown) is provided with a hinged closing plate which seals this aperture when the shrouds are in the closed position and which opens by actuation of a cam arm as the safety cover is opened by means of the triggers immediately prior to use of the trimmer.

Title: Improvements in or relating to registering apparatus
Filed: 1962-05-11
Abstract: 947,124. Mechanical calculators; differential mechanisms. MONROE CALCULATING MACHINE CO. May 11, 1962 [May 18, 1961], No. 18177/62. Heading G4B. The differential actuators 2 are staggered, as shown in Fig. 3 due to the shape of the edge of the actuating bar 10, in order to allow for the serial operation of the stop pins 8. Information is transferred from magnetic disc or tape or punched tape to print wheels 1 (Fig. 2) by means of the differential actuators. Information is stored serially on the record by allotting one sector to a digit value and by indicating within each sector in which orders of the number that value occurs. A sector of the record passes the read station in the same time as the staggered notches on the actuator racks 2t pass positions in which they can be engaged by the stop pins 8. The stop pins 8 (Fig. 2) are operated by signals from the record received through a distributor (Fig. 4 not shown). The pins are held raised by an electromagnet L which is just sufficient to hold the pins against the action of springs 19. When a signal is sensed on the record an appropriate solenoid L 1  L 2  . . . is energized which counteracts the effect of electromagnet L sufficiently to release the selected pin to its spring 19. Synchronism between the record and printer is achieved by clutching the printer to the motor driving the record by means of a start signal on the record which operates solenoid 41 and arm 43. At the end of one revolution or one cycle of the record, cam follower 60 restores the status quo.

The suspension may contain a surface-active agent, such as a sulphonate or phenate and may be prepared by ball-milling the solid material and the liquid at 85 DEG  to 210 DEG  F.  To prevent gel formation the solid material may consist of a mixture of substances of different average particle diameters.  The furnace fuel into which the suspension is injected may be kerosene, gas oil, a distillate or residual fuel oil, or a gaseous fuel such as natural or refinery gas. The introduction of the suspension may be varied to adjust the rate of heat transfer by radiation.  Examples are given.
