Title: Improved sound generator especially for vehicle trainers
IPC: G09B9/22
Filed: 1968-04-10
Abstract: 1,214,517. Aircraft simulators. GENERAL PRECISION SYSTEMS Inc. 10 April. 1968 [10 April, 1967], No. 17338/68. Heading B7W. [Also in Divisions G5 and H3] In an apparatus for simulating aircraft noise for use in conjunction with a fixed-base trainer provision is made to generate signals which, when applied to a loudspeaker 16, simulate: (a) the firing noise of a multi-cylinder internal combustion engine, (b) the propeller noise and (c) the slip-stream noise. A pulse generator 12 comprising an oscillator 61, 62, 71 together with output stages 63, 64, 65 drives a four-stage binary counter 81, 82, 83, 84. A series of gate stages 85, 86, 87 responds to the setting of binary stages 83 and 84 and furnishes outputs through resistors 91, 92, 93 to a common amplifier 94. The resistors have different predetermined values and the result is the production of a stepped wave having a cycle of four steps formed by three values determined by the resistors and a fourth, zero, value when all the gates are inoperative. This wave, when applied to the loud-speaker through potentiometer 51 and amplifier 15, produces a " popping " sound at each level transition which simulates the engine firing noise. The arrangement illustrated is intended to simulate a four cylinder engine, but may be modified for a different number of cylinders. The frequency of the " popping " is controlled in accordance with the simulated motor speed by adjusting the frequency of oscillator 61, 62, 71 by two control potentials. The first is derived from potentiometer 66, which is adjusted in accordance with the throttle setting, whilst the second is obtained via terminal 69 from a computer and represents simulated air speed. Potentiometer 66 is ganged with potentiometer 51 so that the volume of engine noise varies with speed. The propeller and slip-stream noise is produced by the random signal furnished by a white noise generator comprised of a Zener diode 21, amplifier stages 22 and 23 and an emitter follower 24. A first output is derived through a gate 95 which is controlled by the first stage 81 of the binary counter. The result is short bursts of noise synchronized with the engine speed which simulates the propeller noise. A second output is obtained via stage 43 which is controlled by a potential VP representing air speed. The stage is non-transmissive until the air speed exceeds a predetermined value at which slip-stream noise normally becomes apparent.

Title: Improvements in Jib Cranes.
Inventor: GARDNER THOMAS GEORGE
IPC: B66D1/54
Filed: 1917-11-28
Abstract: 120,650. Gardner, T. G., and Hepburn, G. D. Nov 28, 1917. Jib cranes.-In a jib crane having a safety device for limiting the movement of the load in both directions and for limiting luffing, the safety device comprises a brake for the winding drum end means for applying the brake actuated by the travel of the rope along the drum. Means also are provided for supporting the jib and/or the load if the rope breaks. The luffing rope 7 on its way to the winding drum 9 passes between projections 18 on a bar 16 which slides in guides secured to the crane post 5, and is connected also to one end of a rope 19 supporting a weight 21. The brake lever 23 of the brake drum 13 is connected by bars 26 to a weighted lever 28 carrying a roller 30 which runs on the bar 16. As the rope 7 is unwound from the drum 9, the bar 16 is moved to the right, and when the depression 22 comes below the roller 30, the lever 28 falls and the brake is applied. An auxiliary luffing rope 10 passes between projections 25 on the lever 23, and, when sufficiently unwound from its drum 12, comes into contact with the lever and applies the brake. If the rope 7 breaks, the bar 16 is pulled to the right by the weight 21, and the brake is applied by the descent of the lever 28 as before. Similar means (not shown) are provided for controlling the load.

Abstract: 655,641. Boxes or cases. DAVIS, F. W. July 1, 1948, No. 17757. [Class 18] A suitcase or like article of luggage has built-in housings 52, Fig. 8, at two corners at one end of the case to accommodate wheel-carrying brackets 56 that can be swung out of their housings to allow the case to be moved on wheels 12, Fig. 1, each housing being -closed by a hinged lid 60 the axis of which is parallel to the axis of rotation of the wheel and the rocking axis of the bracket. The brackets 56 may be swung outwardly - by withdrawal of a handle 14, Fig. 4, which is connected to each bracket, by a chain 70, wire 80 and a lost motion connection 82, 84, and can be temporarily locked in extended position. When the handle is released, by means of a push button, the brackets 56 move into the housings under the influence of springs 90 and the lids 60 are closed by springs 64. Alternatively, each bracket may be swung outwardly'by means of a pedal, Figs. 11 and 12 (not shown), and engaged in projected position by a step on the hinged lid, which is opened by pressure of the advancing bracket and wheel, the lid and the bracket returning to original positions under spring influence when they are disengaged. Pivoted lugs 20, Fig. 1, on one end of the case permit stacking of additional pieces of luggage on top.

Title: Improvements in hardness testing machines
IPC: G01N3/44
Filed: 1930-06-10
Abstract: 348,915. Testing hardness of materials. WILSON, C. H., 68, Young Avenue, Pelham, Westchester, New York, U.S.A. June 10, 1930, No. 17836. Convention date, April 16. [Class 106 (ii).] In a hardness-testing machine of the kind in which a minor load is first applied to a penetrator resting on the test piece, and then a major load to cause penetration into the.test piece to an extent which determines the hardness, the penetrator member is, when in operative position, guided only by contact with the test piece, and at a point near its opposite end. The test piece is mounted on the top of an elevating screw 11, below a penetrator 43. The head of the machine comprises a web 22 secured to pillars 18, 19 and having side flanges 23 between which is arranged a lever 90 pivoted at 91 for the application of the major load by means of weights 98. A block 50 is mounted between the flanges 23 and is formed with an opening having rounded edges to receive and guide a rod 35 carrying the penetrator 43. The upper end of the rod actuates a pivoted lever 55 which operates an indicator 61 provided with a manually rotatable bezel 65 for adjustment to zero. A bush 75 is slidably mounted on the rod 35 and is pressed upward by a spring 80 to hold it away from the plunger 36. An intermediate sleeve 85 is adapted to transmit pressure from the lever 90 to the bush 75 and thence to the plunger 36. A lever 100 is adapted by means of a link 102 and roller 103 to lift the lever 90 when actuated at its opposite end by means of a hand-operated crank 107 pivoted at 105. A dashpot 115 is adapted to permit quick raising of the lever 100 and to retard its falling. In operation, the lever 90 is lifted to support the load, and the test piece is raised against the penetrator 43 until the plunger 36 is lifted off its seating 33 and the spring 80 is compressed to apply the minor load. The needle of the indicator is then set to zero, and the penetrator and associated parts are supported only at the penetrating point and at the block 50. The lever 90 is then released by movement of the crank 107 and the major load is applied through the sleeve 85 and bush 75 to the plunger 36 and penetrator 43.

Abstract: 624,155 Veterinary appliances. PEIRSON, W. July 7, 1947, No. 17873. [Class 81 (ii)] A drenching-apparatus for animals comprises a reservoir, the air inlet to which is so placed that incoming air agitates the contents. As described, the reservoir is an inverted jar the neck A<SP>1</SP>, Fig. 2, of which is closed by a plug B through which pass an outlet tube H for the liquid and an inlet tube K' for air, the latter being carried the length of the jar and brought down so that its open end is adjacent the plug B. Thus, as a dose is drawn off, the incoming air rises through the remaining liquid. The drench gun described comprises a holder L, Fig. 3, having a measuring bottle N. In use the gun is held vertically and liquid is allowed to run into it by pressing on lever R' and thereby releasing the constriction on the tube at R. The quantity in the bottle is observed through a window L<SP>1</SP> and when this is correct the flow is stopped by releasing the lever R<SP>1</SP>. The nozzle M is then inserted in the animal's mouth and the gun is inverted. The maximum rate of flow from the reservoir may be limited by a screw J' which constricts the tube when tightened.
