Title: Diaphragm-capsule for a pressure-responsive instrument
Inventor: ANGST WALTER
IPC: G01L7/00
Filed: 1952-05-02
Abstract: 704,051. Barometric gauges. KOLLSMAN INSTRUMENT CORPORATION. May 2, 1952, No. 11159/52. Class 106 (2). [Also in Group XXXVII] A diaphragm capsule assembly for a pressureresponsive instrument comprises a stack of diaphragm capsules supported intermediate its ends so that its ends can move in opposite directions upon a change in pressure and a similar stack in line with the first, the four ends carrying spiders extending beyond the peripheries of the capsules, like-moving spiders being connected in pairs to form two units connected to opposite arms of a rocking beam thus averaging the movement of the two stacks and adding their power. Applied to an altimeter with indicating drums, the assembly comprises a stack of similar capsules 17, 18, 19 with central bosses 20, 21, 22, 23 supported in a casing 11 by peripheral lugs 24, Figs. 1, 2, extending outwardly from the centre capsule 18 and interconnected by the bosses 21, 22 while the end bosses 20, 23 carry spiders 26, 27 offset 60 degrees which are connected by rods 39, 40 to spiders 36, 35 carried by a similar stack of capsules 28, 29, 30. The movements of the coupling rods 39, 40 in opposite directions are co-ordinated by a rocking arm 41, Fig. 3, pivoted in bosses 44, 45 of the casing 11 by arms 43 linked thereto by flexible flat springs 46, 47, the ends of the arm 41 being linked to the rods 39, 40 through links 52, 51 and 56, 55, all joins being through similar flat springs. The power developed during expansion or contraction of all the capsules combines to drive the indicator drum 73 through arms 58 clamped to rods 40 by screws 59, for calibration, and linked to a yoke 60 by flat springs 61, a central lug 62 of the yoke 60 being pivoted to an arm 63 of a rock shaft 64 carrying a gear sector 69 meshing with an indicator pinion 70 and counterbalanced by a weight 71. Since the resultant movement is an average of the movements of the individual capsules, errors are minimized and the power developed is sufficient to drive several drums through transfer mechanism. The invention may be applied to sensitive pressure-responsive instruments for actuating electrical contact mechanisms.

Title: Circuits and methods for protecting electrical machining apparatus
IPC: H02H11/00
Filed: 1969-03-03
Abstract: 1,254,587. Protective arrangements. EX-CELL-O CORP. 3 March, 1969 [23 April, 1968], No. 11299/69. Heading H2K. [Also in Division C7] An arrangement for preventing the completion of the circuit of an electrochemical machine, when a short-circuit exists, comprises an auxiliary circuit 22, 24 which is connected across the workpiece and electrode of the machine. The auxiliary circuit comprises a source of supply 32, 36, the coil of a relay R2 and a transistor 54 having its base connected to a voltage divider 46, 48. The contacts R1C of a relay are closed when a start switch (not shown) is operated. Providing there is no short-circuit condition, the voltage across the voltage divider is such as to bias the transistor 54 to conduction, current flowing through the coil of the relay R2, the transistor 54, a diode 62 and closed contacts R5A. The relay R2 closes contacts (not shown) to energize a main relay which closes the supply circuit of the protected machine. Should a short-circuit exist, the transistor 54 is not biased to conduction and the relay R2 is not operated. When the relay R2 operates a further relay is operated to open contacts R5A, R5B and to close contacts R5C to change the circuit constants so that the auxiliary circuit may remain effective while the protected circuit or machine is in operation. In this case when, due to a short-circuit, the voltage applied from the machine to the circuit 22, 24 falls below a level determined by a Zener diode 72, the transistor 54 ceases to conduct and the relay R2 releases.

Title: Improvements in and relating to the manufacture of wire springs
Inventor: RICHARDS STANLEY THOMAS ALBERT
IPC: B21F3/04
Filed: 1955-04-21
Abstract: 800,494. Coiling. NORMALAIR, Ltd. Feb. 22, 1956 [April 21, 1955], No. 11556/55. Class 83 (4). A method of coiling a spring includes the step of bending the wire, which is to form the spring, to a smaller radius of curvature than that of the mandrel, before being laid around said mandrel. A mandrel 2, axially slidable in a sleeve 5, is clutched at 4 to a coaxial, squaresectioned shaft 3, slidable in a spool 10 around which a cord 21 passes. The other end of the cord passes round, and is attached to, disc 11 rigid-with a disc 13 having a weighted cord 22 attached thereto. The discs 11, 13 are rigid on a sleeve 23 journalled in a casing 16 and carrying at its other end a cam-plate 17. A rod 18 pivoted at one end to a lever 19 has a roller 24 at its other end held against the cam 17 by a spring-loaded bell-crank 25, an emergency yielding device being provided in the rod 18. The lever 19 is pivoted at 29, Fig. 2, to a member 30 which carries an axial projection 6, which serves to bend the wire to a smaller radius than that of the mandrel 2 and is rotatably adjustable around the mandrel 2 by screw means 31 so that different parts of the projection 6 may engage the wire. A wire engaging protuberance 20 is also formed on the lower end of the lever 19. The pitch of the springs is adjusted by a lever 7 pivoted at 32 to the member 30 and formed with a slot 33. In operation, to form a conical spring, wire to be coiled is inserted in a hole 1 in the mandrel 2 and attached thereto by bending it around the mandrel by turning the mandrel after the shaft 3 has been unclutched therefrom. The wire is guided over the projection 6 and passed through the slot 33 in the lever 7 and the free end is attached to a weight. The mandrel 2 is then rotated by a handle 8 to enable free turns of wire to be wound thereon. A lever 9 pivoted on the machine frame is then brought into engagement with a helical groove (not shown) on the mandrel 2. The mandrel 2 and shaft 3 are then clutched together and the handle 8 rotated to turn both shafts Through the cord 21, sleeve 23 and cam 17, the lever 19 is rocked about its pivot 29 to vary the position of protuberance 20 and thus vary the ultimate diameter of each convolution, the protuberance 20 preforming the wire prior to its engagement by the projection 6. A helically grooved mandrel need not be used for winding parallel springs, the lever 7 determining the pitch. In another embodiment, Fig. 11, for winding parallel springs, wire weighted at 47 passes through a pitch correcting the lever 45, over a projection 44 and on to a mandrel 42, which is rotated and moved axially by an arm engaging a helical groove therein. Adjustable preforming means 50 bear on the wire as it passes the projection 44 to ensure constant spring diameter. Means 52 adjust the projection 44 around the mandrel 42.
