Title: Improvements relating to liquid-fuel spray nozzles
IPC: F23D11/24
Filed: 1958-05-06
Abstract: 828,402. Fuel atomizers. GENERAL MOTORS CORPORATION. May 6, 1958 [May 6, 1957], No. 14414/58. Class 75(1) A liquid fuel spray nozzle comprises a valve 32 movable by fuel pressure to admit fuel to a chamber 82 communicating through passages 84 with a swirl chamber 46 having a discharge orifice 48, a compression spring 34 pressing the valve to closed position and having one end seated against an abutment 36 movable by a screw 58 to adjust the spring pressure and an aperture 52 in the swirl chamber opposite the discharge orifice 48 for insertion of a tool to rotate the screw. The abutment 36 has a hexagonal surface 56 slidably mounted on a hexagonal surface of an anchor member 54 extending rearwardly from the swirl chamber 46 and the head of the screw 58 has a hexagonal outer surface received in a twenty four sided cavity 66 in the anchor member 54. The tool is inserted through the discharge orifice 48, and the aperture 52 in the swirl chamber and has a hexagonal surface for engaging in a hexagonal cavity 64 in the screw 58. The tool is pressed inwardly to shift the screw 58 axially against the spring pressure until the head of the screw is clear of the twenty-four sided cavity 66. The screw can then be rotated to adjust the spring pressure. The valve 32 is slidable in a bore in an inner body 28 threaded to an outer body 20 and has a triangular metering orifice 80. A fine filter 98 surrounds the inner body 28 and fuel passes therethrough to passages 100 leading to the outer surface of the valve 32. The fuel passing through the valve is cleaned by a coarse filter 72 held in abutment with the outer body 20 by a spring 76. The valve is bypassed by fuel which flows along a grooved passage 88 in the thread 30 connecting the inner and outer bodies and enters the swirl chamber 46 through small tangential passages 86. An air director cap 24 having longitudinal passages 92 and discharge passages 94, 96 is screwed on to the outer body.

[Class 38 (ii).] Relates to a converting arrangement employing grid controlled valves in which a condenser is charged from a D.C. source and discharged through the primary of a transformer and consists in charging the condenser several times during each half cycle of the A.C. to enable a smaller condenser to be used. In the form shown in Fig. 3, during one half cycle the condenser C1 is charged from one half of the battery B through the valve 1 and discharged through the primary of the transformer T through the valve 2, these values having a high frequency control potential on the grids. During the other half cycle the valves 1 and 2 are blocked and the valves I, II are controlled, the direction of discharge through the primary of the transformer T thus being reversed.

Title: Improvements in statistical machines
Filed: 1921-03-24
Abstract: 172,043. Pailthorpe, A. L., and Accounting & Tabulating Corporation of Great Britain, Ltd. March 24, 1921. Statistical machines; counters actuated by reciprocating mechanism. - In perforated-card statistical machines, the cards relating to various items are separately counted by means of a series of counters 4 each connected with a corresponding analysing pin 2, the arrangement being such that, when a pin passes through a perforation, the counter mechanism is set so as to be operated during the subsequent action of the machine. Each pin is provided with a bent end 7 adapted when the pin descends through the card to engage one end 6 of a Bowden wire connected with a lever 21 loosely pivoted on the counter spindle 16, and provided with a spring 22 bearing upon the two arms of the lever. When the wire is pulled, the lever rocks and through one extension of the spring slightly displaces an arm 17, secured to the spindle 16, so as to bring a pin 18 upon the arm into the path of a projection 19 on a frame member 20. During the remainder of the cycle of operation, this member 20 is reciprocated and consequently lifts the arm 17 to operate the counter and then release it to allow it to return to normal position. The analyzing pins have each a projection 15 and a shoulder normally engaged by a duplex spring-controlled bail 12. When a pin penetrates a card, the bail is rocked by the relative movement between it and the pins stopped by the card, and the lower stretch of the bail engages the projection 15 and so produces a positive drive for the pin. Specifications 15473/12 and 128,207, [both in Class 106 (iv), Indicating &c.], are referred to.
