Title: Flying machines
IPC: H01Q1/28
Filed: 1973-03-17
Abstract: 1430304 Aerials ELLIOTT BROS (LONDON) Ltd 1 Feb 1974 [17 March 1973] 12963/73 Heading H4A The landing gear beneath a flying machine incorporates a skid or other extensive member of conductive material, said member being isolated at least at one end thereof from the main body of the machine and being fed at one point only by a feeder from or to transmitting or receiving equipment. As described, a helicopter has a landing gear which consists of two skids one of which, referenced 1, is visible in Fig. 1. Said skid is carried from the main body 2 of the helicopter by struts 3, 4 each of which has an interposed moulded fibre-glass section 5. A cable 7 is connected at one end to the strut 4 beyond the section 5 and at the other end via a stand-off insulator 8 to radio equipment inside the helicopter. The aerial provided by the skid may be extended, for example, by wires extending therefrom to insulators on the main body of the machine. The skid on the other side of the helicopter is insulated from the body 2 in the same way as is the skid 1, and it may either be left isolated or be associated with the skid 1 by means of a cross-connecting cable (9), Fig. 2 (not shown). In another embodiment, instead of providing the insulating sections 5 the struts are mounted in insulating fibre bushes (10), Fig. 3 (not shown), provided in the main body of the helicopter. Considering the arrangement shown in Fig. 1, it is stated that if the strut 3 is not provided with an insulating section 5, but is left as a continuous member from the skid 1 to the main body 2, an arrangement functioning as a so-called skeleton notch aerial will result.

Title: Improvements in or relating to means for controlling the temperature of gases
IPC: F02C9/28
Filed: 1942-09-15
Abstract: 578,766. Gas turbines. HALFORD, F. B. Sept. 15, 1942, No. 12990. [Class 110 (iii)] In periods of heavy load or rapid acceleration, water is sprayed into the working fluid of a continuous combustion gas turbine. A fuel pump D<1>, Fig. 1, is controlled by a lever F and the control of an injection water pump E is connected to the lever through a dash pot E <2>. Rapid movements of the lever Fact through the dash-pot to operate the control of the pump E and cause water injection at D. When the lever F moves past a gate F<4> into an overload region, the piston E<4> makes direct contact with the end E of the control and causes water injection. The dash-pot may be a bellows with a leak and the control may include a servo-motor. In the arrangement of Fig. 3, the delivery of injection water from pump E<14> is controlled by a bypass K and a throttle valve L. When the pressure of the fuel delivered by pump D<2> is high, for heavy loads, that pressure, acting on piston K<2> closes the by-pass K. The throttle valve L is opened by pressure fluid from L<2> when (1) a valve M is opened due to quick increases in the pressure of the fuel supply and (2) when the hand-control moves to a position for steady overload. For the former, the fuel pressure acting on piston M<6> causes piston M <5> to force fluid into a flexible chamber M<1> and the valve M is operated if the movement is beyond the capacity of a leak M <2>. For the latter, a lever D<2> is brought up to the head of and operates a valve N. The fuel pump is controlled by pressure fluid supplied through a construction G<5>, the effective pressure of which is controlled by (1) an over-speed governor J<1> and (2) a valve H under control of atmospheric or compressor-delivery pressure. In another form, the throttle valve L is operated by pressure fluid controlled by (1) the compressordelivery pressure and (2) the delivery pressure of .the fuel pump. The by-pass of the injection water pump is controlled by the delivery pressure of the fuel pump. In another form, the injection-water pump delivers against a spring- loaded valve in the outlet and a spring-loaded valve in a by-pass. A further by-pass has a valve controlled, through a servo-motor, by a thermo-metric device in the combustion chamber. Injection water may be admitted to a spray nozzle E<17>, Fig. 6. Some of the water passes across the end face V of the turbine rotor U and some passes by ports U<2> to a central space U<1> in the rotor.

Abstract: 1,032,550. Unloading lift-cars. GUILBERT Inc. March 26, 1965 [Aug. 24, 1964], No. 12990/65. Heading B8E. A vehicle V is moved out of a lift car 17 by a coupling finger 74 mounted on an impeller which moves along a carriage 52 as the carriage moves out of the lift car. The carriage is moved by a motor M1, Fig. 1 (not shown), which drives through chains 38, 42 and sprockets 37, 41, 43, 45. The latter turn gears 47 which engage fixed racks 53 to move the carriage out of either side of the lift. As the carriage moves gears 87, Fig. 3, engage a rack 85 thereby rotating a shaft 88 which through sprockets 89 and a chain 90 advances the impeller along the carriage. When the vehicle has been pushed out far enough a cam bar is pushed out by either motor M2A or M2B, Fig. 1 (not shown) and this acts on a cam follower 82 to retract the finger 74 thus releasing the vehicle from the impeller. The finger is spring-loaded so that coupling to a vehicle is automatic. Loading and unloading is done automatically and an electric circuit is described which controls the sequence of operations. Lift and access doors 16, 19 are opened and closed and interlocks ensure that outward movement of the carriage only begins when the doors are fully open. Circuits are provided to centre the carriage within the lift car.

Filed: 1919-05-23
Abstract: 138,001. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). May 23, 1919. Reciprocating and oscillating machines.-Electro-ionic means are connected in circuit with an electro-magnetic reciprocating motor to control the motor and to minimize the effects of self-induction. The motor is shown in the form of a hammer with the tool 3, Fig. 1, reciprocably mounted in the tubular part 2 of the casing 1. The pivoted armature 5 imparts a blow to the tool when the winding 4 is energized. The primary of the transformer T is connected to the threephase supply mains, and the secondary, which is a six-phase star winding, is connected to the six anodes 18 - - 23 of the electro-ionic device 7. This device has a cathode 24 heated by current from the battery 9, and a grid 27 connected to the battery 8 and the generator G. The grid-cathode circuit is supplied with current through the rings 28, 29, alternate half waves being suppressed. The hammer winding 4 is connected in series with the discharge device 7 and the transformer T, and the speed of the generator G controls the rate of the blows. In the modification shown in Fig. 2, the winding 33 assists the blow of the hammer and the winding 34 lifts the hammer. These windings are connected to the anodes 40, 41 arranged on opposite sides of the cathode 39 of the ionic discharge tube 35. The generator switching rings are arranged so that the tube discharges from each anode alternately and the hammer windings are therefore operated alternately.

Filed: 1965-03-29
Abstract: 1,108,441. Explosively - actuated tools. UNITED SHOE MACHINERY CORPORATION. 29 March, 1965 [30 March, 1964; 29 May, 1964], No. 13158/65. Heading B4C. [Also in Division F3] An explosively-actuated tool adapted to drive an operating element, such as a fastener element, comprises a striker 28 adapted to impact a charge of a solid relatively-stable low explosive composition 33 and movable in a chamber 23, a port 26 being provided for conducting explosive gases, evolved from explosive deflagration of the charge, to act on the operating element. The chamber 23 is formed in a block 10 secured to a barrel 11 and communicates with the bore 9 of the barrel via the port 26. A firing sleeve 15 is slidable on the barrel and may be retained in its loaded position against the action of a spring 16, by means of a rear lever 17 as shown in Fig. 1. In operation, a charge of explosive composition such as gun powder bonded together to form a pellet 33, is inserted, via a channel 27, into the chamber 23 after the striker is withdrawn against the action of a spring 31. Upon depressing a trigger 22, the sleeve is released and strikes the striker to fire the charge. The expanding gases move the striker and flow, via the port 26, into the barrel to act on the operating element and so drive the fastener into a workpiece. In a modification, a projection is formed on the inner end of the striker and co-operates with a corresponding recess in a plug 25. In the embodiment shown in Fig. 5, the explosive pellet 33 is inserted into a chamber 58 on top of a spring- loaded anvil 59. To fire the tool a striker 65 is moved by a handle 68 and locked in a cocked position by a trigger 73. Upon releasing the trigger, the striker fires the charge and the gases pass via a port 61 and act on a driving piston 53, 54. A rotary magazine 80 for the explosive pellets is mounted in the tool, the pellets being pushed from apertures 81 therein by a spring-loaded ejector.

Title: Improvements in or relating to card stacking devices
IPC: G06K13/14
Filed: 1963-04-03
Abstract: 966,659. Delivering sheets. MAGNAVOX CO. April 3, 1963, No. 13224/63. Heading B6H. In a card delivering apparatus or card stacking device cards 26, Fig. 2, which may be small sized photographic film records of documents, are fed from a feeding magazine 21, Fig. 1, on to a pair of belts 18, on which they are retained by suction ports beneath the upper runs of the belts. The cards are then advanced past a reading station 30, designed to recognize certain cards and thereupon send a signal to one of a plurality of ramp-actuating solenoids 76, to actuate a plunger 77 which via a ramp-operating wire 81 rocks an appropriate ramp 24 causing it to drop its forward end between the belts 18 to pick up the card from the belts. The ascending card enters the bottom part of the appropriate hopper 27, Fig. 4, between lips 87, 85 and its kinetic energy displaces an arm 93, which arrests the card and returns it into abutment with side 98 of a front wall 74 of the hopper 27. The arm 93 of a mioroswiteh 90 actuates a second solenoid 29, whose plunger 33 and plunger head 34 move upwardly between the belts and push the card 26 upwardly past the lips 87 into the hopper 27. The card is retained on the lips 87 by a holddown device 62, whose rod 68 carries a resiliently mounted hold-down pad 113 (Fig. 1, not shown). As the cards accumulate in the hopper 27 they reach a level where the pad 113 moves an actuator arm 72 of a switch 71, which may be used to stop the conveyance of cards so that they may be removed from the hopper into a magazine 121, Fig. 10. Removable or interchangeable receivers or magazines.-The magazine 121, Fig. 10, comprises resilient panels 123 which have inwardlyprojecting tabs 124, which in conjunction with a resilient card-engaging plunger 129 retain the cards 26 within the magazine during storing. To remove the cards from the hopper the pivotally mounted hold-down device 62 is raised and swung aside and the magazine 121 installed on top of the hopper, the caming surfaces suoh as 102, 107, spreading the panels 123, thus spreading the tabs 124 sufficiently to admit cards from the hopper into the magazine. The cards are transferred from the hopper into the magazine by operation of an unloading handle 54, whose upward movement causes the head 34 to elevate the stack into the magazine. Specification 961,113 is referred to.
