Title: Improvements in locking inserts
Inventor: WALSH JOHN
IPC: F16B37/12
Filed: 1960-06-30
Abstract: 938,936. Locking-inserts. JOHN WALSH & CO. (INSERTS) Ltd. Sept. 22, 1961 [June 30, 1960], No. 22872/60. Class 89 (1). A locking insert comprises a flange 13 with a shallow conical surface 14 on its underside and connected to a shank 11 by a neck 12. The insert which may have a plain or screw-threaded bore or a projecting stud, is inserted in a hole in an aluminium &c. block until the flange rests on the block, Fig. .5 (not shown), when it is hammered into the block. The block-material displaced by the flange fills the annular groove 16, Fig. 6, surrounding the neck 12 and prevents withdrawal of the insert which may be of casehardened, cadmium-plated steel. The volume of the groove 16 extending out to the diameter of the shank may be 10% less than that of the metal displaced by the flange. This may be serrated at 17 and formed with a groove, Fig. 2B (not shown), in its surface 14. Two or more flanges 13, 23, Fig. 7, may be provided on the insert.

Filed: 1927-09-03
Abstract: 288,893. Moores, J. Sept. 3, 1927. Reciprocating sieves.-Apparatus for separating the shells and kernels of cracked nuts or seeds, grains, cereals, &c., comprises a reciprocating frame A carrying one or a, number of sieves and having also an abrupt up and down jarring movement, and a feed hopper M one side of which oscillates about a pivot at its upper edge to regulate the supply of material. The frame A is reciprocated on rollers C by the crank and connecting rod mechanism a and has on its underside cam-shaped projections c which cause the jarring movements. The hopper M has an adjustable gate m and a pivoted side m<2> carrying rollers m<4> which engage projections a<4> on the sides of the frame. In the construction shown, the sieve is in two parts with different sized mesh. the small debris passing to a receptacle E and the mixed kernels and shell passing to an oscillating shoot F which is pivoted at f and rocked by a link J driven by a pin j<2> on the frame A. The shoot delivers into a conduit in which a current of air from the fan F<2> carries off the broken shell into the receptacle E<2>, the cleaned kernels being delivered at E<1>. The tailings at G are returned to the cracking machine. The sieves are secured in the frame by T-shaped spring pressed bolts K, Fig. 5.

Title: Sound signalling systems
IPC: G01S1/72
Filed: 1921-09-01
Abstract: 192,725. Baron, H., (Signal Ges.). Sept. 1,1921. Bell and gong signals; subaqueous audible signals.-An electrically operated sound-producer without moved striking parts is operated by aperiodic current impulses or by damped electrical oscillations to give sounds resembling the strokes of a bell. The arrangement is particularly intended for subaqueous sound signalling controlled from a distance, but is applicable to signalling in air. In one arrangement, a tuning fork 5 is struck by a pneumatic hammer 6, the sound affecting a microphone 1 to produce corresponding current variations in the windings of a sound producer 3. In another form, two electromagnetic devices similar to 3 are connected in series, the diaphragm of one being struck by a pneumatic hammer to cause the other to emit a corresponding sound. In these types of apparatus, the oscillation producer 5 &c. may serve also for signalling through the air. In further modifications, the device 3 is operated by discharging a condenser through its coils, and by electric oscillations due to spark-gap discharges, make and break devices being used to control the number and period of sound impulses emitted. In other forms, a single impulse is used to initiate free vibrations of the sound producer, on which the damping of the emitted sound waves then directly depends.

Abstract: 508,915. Making parts of knitting- machines. ZWINGENBERGER, R. Aug. 6, 1938, No. 23318. Convention date, Sept. 10, 1937. [Classes 83 (ii) and 83 (iv)] Punching; riveting.-A device for riveting the side plates to knitting machine sinkers and having means for feeding rivet wire, severing it to length, feeding the side plates to the sinkers and riveting them thereto is provided with an actuating device comprising a plurality of plungers and a head plate to which they are secured. The various parts of the device are operated by plungers 2-5 depending from a head plate 1. As the plate 1 moves downwardly, the plunger 3 engages a member 20 to operate a reciprocating feeding device 16, 17 whereby three wires 8 are fed forwardly into holes in a cutter plate 9. The plunger 2 then engages a pivoted lever 23 which advances the plate 9 and severs the rivet wires. Plunger 5 now comes into engagement with horizontally slidable bars 45, 46 which are moved outwardly to operate pivoted levers 25, 40. The lever 25 moves the cutter further forwards so that the rivet wires are opposite steel pins 28 mounted in a block 27. The lever 40 advances a slide 36 allowing two side plates, one from each of two shoots 31, 32 to descend into riveting position on each side of a sinker which has been placed by hand in a slot 30. Correct positioning of the sinker and plates is assisted by a spring-mounted stop 6 carried by the head plate 1. The plunger 4 now engages the block 27 and the pins 28 push the rivet wires out of the cutter and through the holes in the sinker and side plates wherein they are riveted by a plunger 50 operated by the plunger 5.

Title: Improvements in circuit-arrangements for use in automatic signalling systems for testing a voltage or a resistance in an outlet of a switch
IPC: H04Q1/18
Filed: 1949-09-09
Abstract: 660,521. Electric control systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 9, 1949. [Sept 13, 1948] No. 33376/49. Class 40 (i). [Also in Group XXXIX] In a system in which tests are made over a wiper of a switch to determine the voltage or resistance connected to a co-operating terminal, a current due to a condenser charge or discharge is caused to flow across the point of contact prior to the making of the test. This current which is higher than that used in making the test is used to break down the resistance due to the formation of oxides on the contacts. In the embodiment shown in Fig. 1 in which the device 17 is operated to stop the switch KS when the potential encountered in its bank is equal to that connected up by a numerically set switch MS the condenser 18 produces the necessary discharge current when the wiper passes (e.g.) from terminal 10 to the adjacent terminal 11 having a different potential. The effect may be enhanced by additional condensers 19. Fig. 2 illustrates a circuit for determining the potential connected to an outlet on which the switch EK has been stopped by means unspecified. When the test is to be made contact 25 connects up the voltage comparison device SO and condenser 22 discharges into condenser 24 over the wipers of the intervening switches.
