Title: Improvements in or relating to aeroplanes
IPC: B64C25/14
Filed: 1932-04-27
Abstract: 397,964. Retractable undercarriages. AIRSPEED, Ltd. and TILTMAN, A. H., Piccadilly, York. April 27, 1932, No. 12088. [Class 4.] A retractable divided-axle type undercarriage comprises a landing-wheel supported by a triangular frame, one of the members of which is provided between its ends with a breakable joint controlled by a jack which is operated by hydraulic or other means so that this member can be shortened after the manner of a perambulator hood support to retract the landing-wheel. As applied to a cantilever, low-wing monoplane, a wheel 1 is supported by an axle 6a, a shock-absorbing leg 5, and a radius rod 7. The members 5, 6a are pivotally connected to a front spar 3. The radius rod 7 comprises a part hinged at 7b to rear spar 4 and at 7d to a part 7a pivoted at 7c to the outer portion of the telescopic strut 5. Joint 7d is extended or broken by the action of a ram 8 and in the fully-extended position of the radius rod this joint locks slightly over the dead centre, as shown in full lines in the Figure. For retracting the wheel a uniform pressure is applied to the ram piston, the ram exerting a progressively greater effort as the radius rod turns about its pivot 7c thus compensating for the increasing moment the mass of the wheel, axle, &c., about the pivots on spar 3. In the fully retracted position the wheel 1 projects partly below the contour of the wing, in which position the stub axle rests on a rigid abutment so that the craft may be landed with the wheel retracted without suffering severe injury. A fairing to each wheel may be provided.

Patent GB-377686-A (GB)
Title: Improvements in or relating to methods of and apparatus for calibrating and adjusting electrically operated light valves, such as are used for the photographic recording of sound
IPC: G11B7/00
Filed: 1931-04-27
Abstract: 377,686. Testing and adjusting light valves for sound-recording &c. ELECTRICAL RESEARCH PRODUCTS Inc., 195, Broadway, New York, U.S.A.-(Assignees of Anderson, W. H. ; 8337, Lookout Mt. Road, Hollywood, Los Angeles, U.S.A.) April 27, 1931, No. 12386. Convention date, April 30, 1930. [Class 40 (ii).] A method of calibrating and adjusting the filaments of light valves, such as are used in recording sound, consists in applying to the filament or filaments alternating currents of predetermined amplitude and different increasing frequencies, measuring the response of the filaments at each frequency by photoelectric means, and adjusting the tension of the filaments to give maximum response at each frequency. In this way, the tension of the filaments can be conveniently and accurately adjusted to such a point that the resonant frequency of the filaments is outside the range of sound frequencies to be recorded. In the apparatus shown, there is provided an oscillator O comprising two valves 1, 2 arranged in pushpull connection and adapted to supply alternating currents of predetermined frequencies to the light-valve filaments 14. The frequency supplied is determined by adjustment of variable condenser 3, which is calibrated with a scale from which the frequencies corresponding to different settings may be read off. Resistances 9, 10 control the energy fed back from plates to grids of the oscillator. The filaments 14 are located in the field of a magnet coil 15, so that when oscillating currents are passed through the filaments they are deflected relatively to each other, and control the amount of light transmitted from a constant source 17 to a photo-electric cell 18. This cell is connected to an amplifier 24, the output of which is supplied to a volume indicator 25. The tension of the light valve filaments can be adjusted in any suitable manner, as for example by the screw and lever device 21, 23 shown. In using the apparatus, the known frequency of the oscillator is increased in successive steps, and the tension of the filaments is adjusted each time until the response is a maximum, as shown by the indicating device 25. In this way, the adjustments of the tension of the filaments necessary to make them resonant at various known frequencies are determined.

Abstract: 1,101,745. Mixing gases in flow. F. H. BIDDLE Ltd. 17 March, 1965 [24 March, 1964], No. 12413/64. Heading B1C. [Also in Division F4] Apparatus for mixing hot and cold air in constant proportions has inlet apertures 13, 14 controlled by valve members 30, 32 carried on the ends of a lever 28, 29 pivoted at 27; the ratio of the gases is predetermined by the inclination of the lever which is adjustable by admission of compressed air into the bellows 34 under thermostatic control. The gases then pass into chambers 24, 25 and thence into mixing chamber 36 through apertures in plate 19 controlled by valves as 67, 68. The mixed gases pass through annular aperture 41 and through apertures in the plate 35, annular aperture 75, outlet 76 and filter 83. The plate 35 is suspended by linkage (see also Figs. 2 and 3 not shown) which also carries the valves 67, 68, from the plate 19 in such a way that the plate 35 and valves are balanced by a counterweight 60. If, due to variations in demand on the air supply, the pressure above plate 35 should increase, it will move downwardly and actuate the valve members 67, 68 to restrict the inlets to the mixing chamber, thus maintaining the gas flow constant: and conversely for a reduction of pressure. The replaceable filter 83 is retained by an outlet baffle 85 which is vertically adjustable, and detachable.

Abstract: 514,117. Bottle-washing machines. CHERRY-BURRELL CORPORATION. April 27, 1938, No. 12586. Convention date, May 6, 1937. [Class 138 (i)] A bottle washing machine comprises a soaking tank 16 and an upper casing 17 provided at the sides with rails 18 supporting-the rollers 19 of an endless conveyer 20 for the bottles which are loaded on to the conveyer at A, rinsed at B, soaked at C. then inverted and allowed to drain at D, washed at E, rinsed at F, chlorinated at G and finally unloaded at H. Bottle carrier frames 30 extend across between the inner links 18 of the two chains of the conveyer and each pair of frames 30 is bridged by webs 31, 32 supporting respectively movable and fixed spring jaws 33, 34 for gripping a row of bottles by their beaded mouths; the movable, jaws 33 mounted in pairs on webs 31 grip the bottles under the influence of springs 35 and are retracted for receiving and releasing the bottles by cams 53. The conveyer is given a step-bystep movement through a distance equal to that between the bottle carrier frames by means of a pair of levers 65 on a rock shaft 67 oscillated by a slotted arm 68 and crank 69, each of the levers 65 carrying a pivoted dog 70 which rides over one of the conveyer rollers 19 on movement of the lever in clockwise direction, then drops behind it and propels the chain one step forward on movement of the lever in the reverse direction. At the loading station A the bottles are supported in correct position for being gripped by the jaws by a supporting spring 62 and steadied against tilting by a spring 63 and as soon as the bottles move away from this station the gripping jaws 33 are released from the cams 53 and grip the bottles. At B the bottles are rinsed by water from a pipe 75 having an orifice for. each bottle controlled by a sleeve valve operated by a lever 81 actuated by contact with the bottle and returned by a weight 83 whereby if a bottle is lacking the jet opposite the empty position remains inoperative. After soaking in the tank 16 the bottles become partly inverted at D and are allowed to drain, more rapid cooling after soaking in the hot liquid being promoted by providing an opening 104 and stack 1043 on the casing at this point, and also a pipe 1040, Fig. 13, having its ends opening through the sides of the casing and screened at 1041 and slotted at 1042, thus admitting fresh air. At E the bottles are washed internally by twin jets delivered from a header 85, Fig. 14, through inclined orifices 852. Over one row of these jets the bottles are washed externally by spray rings 87 carried by a pipe 88 mounted in vertical carriages 95 which are raised and lowered intermittently by a pitman 98, lever 99 and groove cam 101. At F the bottles are rinsed by water from sprays 108, 109 and at G by a chlorinated jet from a pipe 110. Thereafter at H the bottles are released from the gripping jaws, tilted by arms 55 on to hinged receivers 60 and delivered thereby to a cross conveyer 61. Specifications 514,130 and 514,293 are referred to.

Abstract: 234,123. Soc. Anon. des Etablissements Ballot. May 16, 1924, [Convention date]. Arrangements of hand and foot gear in conjunction with controlling-apparatus.-The ends of the band 7 of an internal expanding brake are provided with cheeks 9 which normally rest against a stop 10, so that when the band is engaged with the drum by a cam 16, one end of the band remains in contact with the stop, the consequent lateral displacement of the cam being permitted by providing a slot in the brake drum cover plate and mounting the cam-shaft in' a ball-and-socket joint supported on the vehicle axle. When the brake is released, springs 13 - - 15 withdraw the band from the drum, and it is then supported on radial arms 11 adjustably mounted in the support 1 of the wheel. The spring 13 is made considerably stronger than the spring 14, so that when the brake is applied during forward travel in the direction shown by the arrow f, the end of the band to which the spring 13 is attached does not move away from the stop at all. When, as shown in Fig. 4, the brake is applied to a steering-wheel, the cam is tapered upwardly, its longitudinal axis is located in line with the steering-pivot, and its ends are rounded to allow the cheeks 9 to pivot round it when the wheels are steered, whilst the cam-shaft 17 is passed through a slot in a bracket 24, so that it is guided in its lateral movements. The bracket 24 may be replaced by a spring attached to the shaft 17 and to the brake drum cover plate. In modifications, the band is replaced by a number of rigid shoes hinged together, and the arms 11 are replaced by a circular support through which passes a number of adjustable set screws on which the band is supported.

Abstract: 108,758. Wade, H., (Universal Winding Co.). Sept. 13, 1916. Winding-machines.-To effect an increase in the taper of the cone as it is being wound in accordance with the method described in Specification 107,757, [Class 120 (iii), Yarns &c.], the traverse is at intervals shortened and then lengthened step by step, the variation being effected at one end only of the traverse. The guide G is controlled by the arm l<1> of a bell-crank lever L pivoted at l to a cross-head M sliding on bars R, and reciprocated by a cam O. The arm l<2> of the bell-crank carries at its end a bowl s guided in an arm T pivoted at u to a fixed bracket U. The arm T carries a stud v engaging a cam track w in a worm-driven cam W. The track w is partly circular and partly curved in substantially a heart curve. Whilst the stud v travels round the circular part, the traverse is unaffected by the arm T and is uniform. When the stud enters the curved portion w<3>, the arm T is depressed and the traverse is gradually shortened, the layers being stepped back from the apex c. The curved portion w<4> effects a gradual lengthening of the traverse. The arrangement of the lever T, as shown in Fig. 1, enables the traverse of the thread guide to be greater than the throw of the cam 0. The rotation of the cam W can be varied to adjust the number of changes in the traverse in the completed cone.

Abstract: 560,831. Gas compressors. COMMERCIAL STEELS & FORGE CO. (AUSTRALIA), PTY., Ltd. Sept. 15, 1942, No. 12991. Convention date, Sept, 16, 1941. [Class 8 (i)] [Also in Group XXVI] The cylinder 10 of a gas compressor is mounted with clearance from the outer casing, and reciprocated between end covers 14, 15 by the friction of the piston, thus making a seal with each cover alternately while gas is drawn in through the gap between cover and cylinder at the other end. Compressed gas is delivered through ports 27 controlled by spring-pressed valves. The cylinder weight is partly borne by a spring 17 pressing on a cylinder collar 16 and a ring 18 screwed on the casing or an inner wall 19. Air &c. is admitted by a port 47 and may be under pressure from a fan ; surplus air may be used to cool the cylinder externally, passing out by the port 51 to atmosphere. Cooling water &c. is circulated through the cylinder head by pipes 37, 38. The piston 49 is driven from shaft 64 through a pin 62 in a block 63 sliding in a frame 60 which is hollow for circulation of cooling oil &c. to the piston interior by the pumping action of a frame extension 69. A pair of pistons 49 may be connected oppositely to a single frame 60. The compressormay be unloaded at desired pressure by causing grooved slidable blocks under this pressure to engage stops on the cylinder and hold it in position with both ends open.
