Title: Improvements in and relating to machines for testing stems for electric incandescent lamps and similar tubular articles
IPC: H01J9/32
Filed: 1935-06-11
Abstract: 444,933. Testing valves before putting into service. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. June 11, 1935, No. 16813. Convention date, June 12, 1934. [Class 135] [See also Group XI] A device for detecting the absence of an inlet or exhausting-aperture in a stem for an electric lamp, or similar tubular article such as the stem of a valve for a cycle tyre, comprises an air line which is adapted to engage the exhausting-tube of the stem so that air under pressure can be forced through the line and escape normally through the exhausting- aperture, the absence of an aperture in a stem causing an increase of pressure which produces the expansion of bellows operating controlling- mechanism for indicating the presence of the defective stem. A pipe 31 connected to a source of air under pressure is connected through a T-joint 30 to a bellows 32 and pipe 28 which is connected by a flexible hose-29 to a tubular plunger 12 provided with a rubber tip or nozzle 11 adapted to be lowered into engagement with the exhausting-tube 13 of a lamp stem 10. The plunger 12 is slidably mounted in a horizontal bracket 14 and is lowered in two movements on to the exhaust tube 13, first by a lever 18 which engages a pin 15 on a clamp 16 on the plunger 12 and lowers the pin into contact with a latch 17, the lever 18 being turned by a rod 20 operated by mechanism not shown ; the latch 17 being subsequently withdrawn by a rod 24 operated by a rocking- lever 23 to allow the plunger 12 to drop until the tip 11 engages the exhaust tube. The lever 23, through an arm 37 projecting laterally therefrom, controls the movement of a pendulum 36 provided with an upper extension arm 38, the lower end of the pendulum forming a latch 40 adapted, in the vertical position of the pendulum, to arrest the vertical movement of a cam-operated rod 41 and disengage a coupling between a driving wheel 42 and driven wheel 43 connected to a cam-shaft 47. The pendulum is brought into its vertical position by a sliding rod 35 which is moved by the expansion of the bellows 32 and engages the pendulum arm when a defective stem is beneath the tip 11 of the air pipe 12.

Abstract: 1,045,778. Electric analogue calculating. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL and SOC. MAROCAINE DE RECHERCHES, D'ETUDES ET DE DEVELOPPEMENTS " SOMAREDE." April 23, 1964 [April 26, 1963], No. 16967/64. Heading G4G. An arrangement, Fig. 1, for solving a system of equations and inequalities such as: comprises: generators G1 ... Gq producing outputs proportional to the unknown x1 . xq; error calculating means C receiving the generator outputs, and developing error signals f1...fp and g1 . . . gp; and a switch unit R receiving the error signals and producing control signals for the generators G1 ... Gq, the g error signals being coupled through an intermediate device I, which puts into operation circuits corresponding to g = 0 when x1... xq tend to make g<0 and disconnect these circuits in the opposite case. The device I comprises an integrator or amplifier S, Fig. 2, having a switch D in its input and its output connected to the switch unit R. Switch D is controlled by a sign detector DS fed by a subtractor CS which delivers an output g-#. If g is greater than zero, switch D is in position 2 shorting out integrator S so that DS is controlled only by signal g, and the switch D will remain in its 2 position. If g goes negative, switch D changes to its 1 position and circuit S provides an output # whose effect is to modify the control voltages of generators G1 ... Gq so as to maintain g = 0. DS is then controlled by a signal -#. In a modification of the unit I, Fig. 5 (not shown), a second switch ganged with switch D disconnects integrator S from unit R in the position 2 and connects an earth potential to.unit R. An alternate form of unit I, Fig. 6 (not shown), employs diode switches D1, D2 suitably biased to provide the necessary switching operation.

In apparatus for feeding coiled springs to a machine for grinding their ends, e.g. the machine described in Specification 740,421, [Group XXIII], the springs are carried between the grinding wheels by a rotary carrier 151 and are fed to the carrier from a supply hopper 10 through a vertical shoot 11 provided with means 25, 26 for releasing them one at a time, this means being actuated by an oscillatable member 22 in such a way that when the shoot is in register with a spring-receiving means on the carrier, the bottom spring is released and falls into the carrier while the other springs are retained, after which the member 22 moves in a direction contrary to the direction of rotation of the carrier and control means 261 obstructs the outlet from the shoot. The shoot 11 is connected to the hopper 10 and is rotatably mounted in a bush 12 carried by an arm 13 which is urged by a spring in a direction opposite to that of the carrier 151 into contact with a buffer spring. The arm 13 is mounted freely on the spindle which drives the carrier 151. The spindle is connected also by chain- and-sprocket gearing to the upper part of the shoot. A tubular feed block 16 secured in the end of the arm 13 forms a continuation of the shoot and carries a bracket in which is pivoted a member 22. The upper part of this member is connected by a rod 252 to one arm of the pivoted release member 25 and the lower part is connected by a rod 262 to the other release member 26.
