Abstract: 549,910. Valves. STEVENSON, H. A. Aug. 27, 1941, No. 10930. [Class 135] A valve device opened by hand and retained open by an electrically-actuated catch, particularly for controlling the flow of gas to a gas fired furnace or stove has a single loading device for closing the valve and for moving the catch to its release position when the electrical supply is interrupted. in the form shown in Fig. 1, the valve is loaded to close by a pair of tension springs anchored to the valve casing and to a transverse rod 1a secured to the valve spindle 2. The valve is moved to the open position by a hand lever 3 and is retained in the open positiom by pivoted catches 6b engaging a plate 10 secured to the valve spindle, when a solenoid 4 is energized. The matches are pivoted to depending lugs on a plate 8 supported by pillars 5 and are connected by links -9 to a pin 9a on ,the solenoid core. The solenoid circuit is closed through a switch 11 closed when the valve is in its open position by a tappet 14 on a plate 15 secured to the valve spindle acting through a spring-loaded plunger housed in a casing carried by the plate 8.

Abstract: 499,395. Fluid pressure servomotor control systems. SOC. GENERALE DES CARBURATEURS ZENITH. April 20, 1937, No. 11317. Convention date, April 22, 1936. [Class 135] In a supercharged aircraft engine wherein the amount of air or mixture supplied is controlled both by a lever, (not shown), operated by the pilot and the movement of which in the direction of increasing the amount of air or mixture is limited by a stop, and by a servomotor, (not shown), the valve 24, Fig. 3, controlling the servo is connected to an intermediate point of a floating lever 44, one end of which is connected to a closed expansible capsule 33 arranged in a chamber 35 to which induction pressure is communicated through a pipe 37, while the other end of the lever is connected to a closed expansible capsule 34 arranged in a chamber 36 open to the atmosphere through a pipe 39, the arrangement being such that the maximum permissible induction pressure either increases or decreases as the altitude increases. The servo may control an auxiliary throttle valve or may modify the action of the pilot's control lever on the main throttle, or may actuate the control member of a variable-delivery or variablespeed supercharger. Alternatively, the two capsules may act directly, or indirectly through levers, on the two ends of the valve 24, or, as shown in Fig. 6, the two capsules 33 and 34 may be arranged in series to act directly on one end of the valve. Induction pressure may be supplied to the interior of the capsule 34, or the latter may be replaced by a piston, one side of which is subjected to atmospheric pressure while the other side is subjected to induction pressure. Specifications 358,289, [Group XXVII], and 456,975 are referred to.

Abstract: 325,159. Stange, L., and Rheinische Metallwaaren-und Maschinenfabrik. April 12, 1929. Breech actions, sliding barrel and breech-block. -The barrel c, which is shown in the firing position, is rigidly connected to the breech-sleeve b, and the latter is provided with a slot in which is mounted a pivoted lever d. The front arm d<2> of the lever d projects through this slot and fits into a recess f<1> in the breech-block f. The barrel, breech-sleeve and breech-block are thus rigidly connected. On the recoil, these parts move rearwardly together until the arm d' of the lever d meets the surface a<3> of the casing a. The lever is thus rotated and the arm d<2> is lifted thus releasing the breech-block f, which continues its rearward movement alone. The sear n holds the breech-block in its rearmost position. The firing device consists of a firing pin g, a retracting spring m, and a pivoted leverk. On firing, the breech-block moves forward and the lever k strikes against a fixed stop a<7>- The rotary movement thus given to the lever k is transmitted to the arm k<2> which strikes the firing pin and fires the gun. The relative positioning of the locking surface a<5> and the hammer-actuating stop a<7> is such that the breech is locked before the forward travel of the barrel and breech-block is complete, and the discharge takes place at the end of the forward movement.

Title: Apparatus for correcting rotary unbalance

Abstract: 1,015,037. Measuring rotar unbalance electrically. GENERAL MOTORS CORPORATION. March 19,1964 [April 18,1963],No. 11665/64. Heading G1N. The dynamic unbalance of a rotor is measured at each of two bearings and used to control a drill which automatically removes the correct amount of material at the correct angular location. As shown (Fig. 1), the unbalance of a rotor 10 is measured at the bearings 16, 18 by pick-ups 22, 24 respectively, each unbalance signal being compared with a reference angle signal induced in pick-up 26 by a mark 28, to produce a first voltage representing the angle of the unbalance, indicated at 32 and stored at 38, and a second voltage representing the magnitude of the unbalance, indicated at 34 and stored at 48. The angle signal at 38 is used to operate an indexing mechanism 40 which rotates the rotor 10 until the unbalance mass is located under a drill bit 42; the magnitude signal at 48 is compared with a signal representing the depth of a hole produced by drill 42, modified in accordance with the shape of the drill bit, the drilling being stopped when the signals are equal. Unbalance removal is initiated by automatic control 60 (Fig. 2) which feeds the magnitude signal at 48, stored across a capacitor 58, to cascadeconnected triodes 66, 68 and energizes a relay 72 to close the energizing circuit for a drill advance motor 75. When the drill bit 42 touches the surface of the rotor 10 a switch 90 is closed, energizing relay 82 and opening contacts 84 so that further advance of the drill feeds a voltage from the resistance winding 78 of potentiometer 50 to the grid of valve 86, and a proportional change in voltage is developed across cathode resistor 88. This voltage is modified by circuit 56 in accordance with the shape of the drill bit 42 and the moment of the mass removed about the rotational axis of rotor 10, and the modified voltage is subtracted from the unbalance voltage across capacitor 58 to stop the advance of motor 75 when they are equal.

Abstract: 1379479 Weighing apparatus used for counting JOHN CHAILLON & SONS Inc 13 March 1972 11701/72 Heading G1N and G1W In a balance for counting uniform manufactured articles, a balance beam supported at a pivot 18 comprises a generally vertical arm 20 which supports a known number of said articles, and a generally horizontal arm 21 which supports a quantity of said articles to be counted, the vertical component of downward deflection of a point on the arm 21 at equilibrium being directly proportional to the ratio of the weights supported by the two arms, and hence to the ratio of the numbers of articles. With the scale pans 22, 23 empty, the beam is balanced so that its centre of gravity lies at the pivot 18, using counter-balancing weights 26, 27, the arms 20, 21 being respectively vertical and horizontal at the datum position. The end of arm 21 forms a pointer moving over a fixed vertical scale 30. Alternatively, the induction coupling core (60), Fig. 6, (not shown), of a differential transformer may be suspended from the arm 21, to obtain an electrical output signal. Another readout arrangement Fig. 7, (not shown), uses an opaque mark (71) on the arm 21 movable between a vertical light slit and a photo-detector. In Fig. 5, the articles to be counted are put in a pan 40 on a tape 41 round a pulley 42 rigid with the arms 45, 46 of the beam. The scale 50 suspended from the horizontal arm 46 moves against a fixed pointer 51. Alternatively the scale may be on a transparent strip for use with an optical projection system. A further readout system uses a vertically movable follower engageable with the horizontal arm 21, a rack on the follower engaging a pinion on a pointer shaft to move the pointer over an arcuate scale.
