Title: Improvements relating to aircraft incorporating vertical thrust generators
Inventor: PRIBRAM EDWIN
IPC: B64C29/00
Filed: 1956-09-20
Abstract: 871,470. Direct-lift aircraft. FAIREY CO. Ltd. Sept. 19, 1957 [Sept 20, 1956], No. 28814/56. Class 4. [Also in Group XXVI] An aircraft comprises a horizontal propulsion thrust generator, a wing having a downwardly converging duct with a spanwise elongated inlet in the wing upper surface and a spanwise elongated discharge aperture in the wing lowersurface, a conduit extending longitudinally within the duct, fed by a source of high velocity gas, and discharging through a nozzle in the lower wall of the conduit, and two blade like flaps movable between a withdrawn position in which they are located within the duct on either side of the conduit, and an operative position in which they project downwardly below the wing lower surface and form an elongated nozzle forming an extension of the duct. Each wing 10 is provided with one or more downwardlyconvergent ducts 13 formed by spanwise panels located between the spars 31. The inlet of each duct in the upper surface of the wing is closable by a pair of doors (one only, 32, of each pair being shown in Fig. 3) mounted on chordwise axes for operation by jacks 34, from the open positions shown to positions flush with the wing surface. The lower part of each duct may be extended by blade-like flaps 16 each mounted by arms 36 for rotation about spanwise axes by a jack 37 from the inoperative position shown by full lines in Fig. 2 to the extended position indicated by chain-dotted lines, where their cambered surfaces form a slightly divergent extension of the main duct. Each duct contains a spanwiseextending horseshoe section distribution con-' duit 20 having an elongated orifice 21, each conduit being connected to an extension pipe (not shown) branched from a main jet pipe. The jet pipe and each extension pipe carries a valve whereby the efflux from the engine may initially be prevented from passing into the jet pipe and directed to the extension pipes for discharge from orifices 21 to provide direct lift during landing and take-off. For forward flight, and at a suitable altitude, the valves in the extension pipes are closed and that in the jet pipe opened to provide a gradual transfer from vertical to forward flight. Fuel may be burned in the extension pipes and/or in the combustible mixture formed by the efflux from orifices 21 and the entrained air drawn through duct 13 by the ejector effect of the nozzles. According to the Provisional Specification, the thrust generator may be mounted in the fuselage. The aircraft may be mounted for take-off on a carriage with its fore-and-aft axis vertical, the thrust generator then being at the rear of the fuselage.

Title: Machine for Automatic Bottle Filling.
IPC: B67C3/24
Filed: 1968-06-17
Abstract: 1,188,888. Bottle filling machine. A. SIMONAZZI, R. SIMONAZZI and A. SIMONAZZI, [trading as SIMONAZZI A. & L.]. 17 June, 1968 [20 June, 1967; 21 March, 1968], No. 28825/68. Heading B8T. A revolving table back-pressure bottle filling machine, comprises a vertically adjustable, annular tank 1, mounted under a rotatable plate 2 supported by columns 3, having equallyspaced, underlying filling heads 14, and bottle supports 54, operated by hydraulically controlled jacks 13, both the jacks 13 and the columns 3 being attached to a rotatable plate 6. The. axes of the jacks are radially displaced inwards from the filling heads to aid in protecting the jacks from glass fragments, should a bottle be broken during filling. An apron 24 serves the same purpose. The filling heads 14 comprise a body 26, Fig. 5, a valve member 25 mounted in an opening which communicates with bottles 15 through pipes 28, and a coaxial collar 41, supported beneath the body 26 on a sliding column 42. A pipe 53 passes through a stem 51 and communicates, via a valve 29, with the space above the liquid in the tank. A pin 30 controls the valve 29 and may be acted upon by a pin (34), Fig. 6 (not shown), which initiates a snifting operation. Operation.-On rotation of plates 2 and 6, each bottle is raised by member 54, until its neck engages the collar 41 which, on further raising, engages the body 26. A valve (39), Fig. 3 (not shown), is actuated, causing evacuation of the bottle and a plate (43) is rotated by engagement of a lever arm (50) with a pin (46) thereby operating, through the action of a cam 44 the pin 30 which opens valve 29 causing the bottle to be counter-pressurized. Valve 25 then opens and liquid flows until it obstructs the orifice at the bottom of pipe 53, thus cutting the flow of gas from the bottle to the space above the liquid in tank 1, and hence stopping the liquid flow. Pin (34) then axially displaces pin (30) thereby closing valves 25 and 29 and, due to pin (34) acting on a valve (36) vents the bottle. The bottle 15 is then lowered. If a bottle breaks, the collar 41 falls, thus releasing pin 30 and closing valves 25 and 29.

Abstract: 1,182,947. Vehicle cleaning apparatus. G. McMILLAN. 14 June, 1968 [22 June, 1967], No. 28866/67. Heading B7J. Apparatus for supporting a horizontal brush for a vehicle washing apparatus comprises an inclined frame 14 pivoted about a horizontal axis 15 on side frames 10; a sub-frame 19 mounting a brush 13 and its electric motor driving means 20, 21, 22 and fitted with rollers 23, 24 which run on guides 25 provided at each side of the frame 14; and an hydraulic piston and cylinder device 35 for moving the frame 14 into a reversely inclined position, Fig. 4 (not shown). Initially, the brush 13 is in the position shown by the broken lines in Fig. 2, but when the front of a vehicle is urged from the left of the Figure against the brush the brush begins to ascend the guides 25 aided by counterweights 27, thus maintaining intimate contact with the vehicle. When the brush reaches the roof of the vehicle the actuating rod 46 of an electric limit switch 45 is displaced by the front edge of the vehicle roof: The switch 45 is in an electric circuit with a limit switch (49) Fig. 3 (not shown), having an arm (50) contacted by the vehicle for opening the switch 49. When both switches are closed the circuit is operated to actuate the device 35 which reverses the inclination of the frame 14. Thereafter the brush moves, under gravity down the frame 14 until the vehicle has cleared the apparatus. As the vehicle clears the apparatus an electric switch 47 is operated whereby the device 35 is caused to return the frame to its original position. During this movement guide wheels 42 on the brush shaft move along rails 43 on the side frames 10. The apparatus may be static or movable relative to a vehicle, and is used. in combination with vertical rotary brushes for cleaning the vehicle sides, in known manner.

Title: Improvements in or relating to exposure timers for photographic enlargers
IPC: H03K17/288
Filed: 1959-08-26
Abstract: 908,841. Photo-electric control of photographic printing. ELECTRONIC S.A. Aug. 26, 1959 [June 29, 1959], No. 29234/59. Class 40 (3). Relates to exposure timers for photographic enlargers in which a capacitor discharges through a photo-conductive cell to eventually cause a valve to conduct and energize a relay to cut-off the supply to the printing lamp. According to the invention the valve includes a screen grid biased via a potentiometer adjusted to compensate for the dark resistance of the cell. Momentary closure of switch 11 causes capacitor 12 to charge through the control grid-cathode diode circuit of pentode 16 and the subsequent switch opening cuts off the valve; consequential cut-off of valve 22 de-energizes relay 4 and the printing lamp is energized. The capacitor then discharges through photo-electric cell 5 illuminated by reflected light from the print on the enlarger baseboard, and potentiometer 20 is adjusted to allow sufficient control grid current to flow to compensate for capacitor discharge through the dark resistance of the cell. Potentiometer 15 is adjustable to set the voltage to which the capacitor is initially charged and hence exposure time. When the capacitor has discharged to the point at which valve 16 conducts relay 4 is energized and the printing lamp supply interrupted. In a second embodiment a Schmitt trigger circuit controls relay operation, Fig. 3 (not shown).
