Abstract: 709,355. Transmitter attachments. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 14, 1952 [Aug. 17, 1951], No. 20459/52. Class 40 (4) A sound-probe comprises a diaphragm having directional characteristics, acoustically connected by a long narrow tube to an electroacoustic transducer. As shown, Fig. 1, the diaphragm 6, which is arranged to have a kidney-shaped characteristic, may receive sound on its front face and also its back face via the aperture 8. A cylinder 12 rigidly connected to the diaphragm is acoustically sealed by a rubber ring 16 to the long thin tube 1 so that the motion of the diaphragm is conveyed as pressure waves along the tube to the diaphragm 20 of a moving coil microphone. A dome-shaped acoustic resistance 18 mounted immediately behind the diaphragm coupled with the space inside the cylinder 9 comprises an acoustic phase shifting network for providing the kidney-shaped characteristic. The acoustic resistance 25 and the space 26 serve to close the tube with its characteristic acoustic impedance. If the space between the cylinder 12 and the tube 1 is sufficiently small the rubber ring 16 may be omitted. In a further embodiment, Fig. 3, the diaphragm is given an 8-shaped characteristic sound having access to the back of the diaphragm (as well as to the front) through holes 31 in the casing. The diaphragm is rigidly attached to the lid shaped member 33 connected to a resilient attachment 34 which seals the end of the tube 1. Specification 428,144 is referred to.

Title: Improvements in and relating to cartridge reloading machines
IPC: F42B33/00
Filed: 1927-08-05
Abstract: 297,922. Spencer, E. P. Aug. 5, 1927. Cartridge-loading machines. -A cartridge reloading machine comprises a supporting table 1, Fig. 1, to which is attached a base plate 4 carrying an upper structure by pillars 7, lower and upper plungers 23, 55 worked by levers 20, 51, a gate member 32 pivotally mounted on one of the pillars 7 and provided with a barrel 36 for guiding an auxiliary plunger 37, a cartridge holder 42, and devices for decapping and recapping a cartridge and for forcing a projectile into the same by the operation of the plungers. For decapping and recapping, the cartridge is inserted nose downwards into an open notch 57 in the holder 42 where its base is gripped by one or two plates 46, Fig. 7, clamped to the holder 42 by set-screws 44. The lower plunger 23 is then moved up by the handle 20, and lifts the auxiliary plunger 37 which carries a rod 40 provided with a pin 41 for ejecting the cap from the cartridge. A fresh cap is then placed in position and rammed in by a die 56 on the upper plunger 55. The capped cartridge is removed from the machine and replaced by a bushing 67, Fig. 11, containing a plunger 68, which is attached to the plunger 55 in place of the die 56. The barrel 36 and the plunger 37 are also removed and replaced by a barrel 59, into which a capped carriage A is inserted with a bullet D loosely in front of it after a charge of powder has been put in the cartridge The base of the cartridge is held up by a plate 64 hinged to the member 32 on a screw 65 and fastened by another screw 66; and the bullet is rammed into the cartridge by the plunger 68 forced down with the plunger 55 by means of the handle 51. The plunger 68 is guided in a cap 70 screwed over the end of the barrel 59. After this bulleting operation, the plate 64 is swung out, and the plunger 23 raised to bring hooks 28 thereon into engagement with the base of the cartridge. The plunger 23 is then again depressed and the loaded cartridge extracted from the barrel 59 by the hooks 28. In a modification, Fig. 13, the cartridge A and bullet D are introduced from the bottom into a barrel 59a provided with a screwed cap 76 having an adjustable screwed stop 77 for the nose of the bullet. The ramming of the bullet into the cartridige is performed by the upward stroke of the plunger 23, no plunger 68 being used in this modification; but the extraction is performed by the hooks 28 as in the first construction. A collar 32a having notches for the passage of the extractor hooks 28 may be fitted in the member 32 around the base of the cartridge.

Title: Improvements relating to electric arc welding apparatus
Inventor: HOULDCROFT PETER THOMAS
IPC: B23K9/133
Filed: 1951-09-03
Abstract: 710,278. Automatic control systems for arcs. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 3, 1952 [Sept. 3, 1951], No. 20767/51. Class 38(4) [Also in Group XXII] In a system in which a consumable electrode in electric arc welding equipment is automatically fed by the output member of a differential gear the two input members of which are driven by electric motors, the armature winding of one electric motor and the field winding of the other are supplied from a constant voltage source, while the remaining armature and field windings are controlled by the arc voltage so that as the speed of one motor increases with arc voltage the speed of the other decreases. In Fig. 2, shunt motors 1 and 2 are coupled to the input members of the differential gear associated with a welding head, (see Group XXII), armature 6 and field 3 being supplied through a rectifier 19 and a variable ratio constant-voltage transformer 18, from A.C. mains 15. Armature 10 and field 7 are supplied through a rectifier 25 from the voltage across an A.C. or D.C. arc 11. The arrangement is such that an increase in arc voltage increases the speed of motor 1 and decreases the speed of motor 2 to increase the rate of feed. On starting, with the switches in the position shown, supply of cooling water to the welding head closes a switch 17. Main switch 16 is then closed and transformer 18 adjusted until the desired arc voltage is indicated by a centre-zero voltmeter 26. A switch 14 is then closed to operate an electromagnetically operated contactor 12 closing the arc circuit and closing contacts 22, 30. The closing of contacts 22 starts motors 1 and 2. The closing of contacts 30 connects voltmeter 26 so as to indicate the difference between the voltage of rectifiers 25 and 19. This voltage is set to zero after the arc strikes, by adjustment of a resistance 5.

Abstract: 863,123. Photo-electric analysis of documents. BASSLER, F. July 2, 1957, No. 20867/57. Class 40(3) [Also in Group XIX] Apparatus for the photoelectric analysis of documents, cards, films, football pool coupons, &c., the surface of which is sub-divided into areas and on which data is recorded by marks selectively applied in such areas, wherein each area is scanned by a photo-cell responsive to light reaching it only from a small portion of the area to produce a substantial proportional change in the continuous unidirectional current of the photo-cell in accordance with each change of light intensity due to a mark, a signal proportional only to said change in current being derived and added to a predetermined proportion of the differential of the signal to produce a signal impulse which is caused to actuate registering or responding means whenever it exceeds a predetermined level. In the exemplified embodiment a football coupon, Fig. 5, in which a different twelve match forecast can be made in each of eight selection columns M-T, is analysed by apparatus including twelve photo-cells 10, Fig. 3 arranged in a pattern corresponding to the arrangement of marks for a correct forecast in a selection column. A further photo-cell 7 responds to control markings U on the coupon and serves to cause operation of the photo-cells 10 at each selection column M, N...T during the feed of the coupon beneath the photo-cells 10. The output of each of the photo-cells 10, for each selection column as it is scanned is processed to obtain the sum of the difference and differential signals to produce signal impulses which are applied to triggers 15, one corresponding to each photo-cell 10, only such triggers 15 which correspond to photocells 10 sensing a correct forecast being operated. The sum of the output of the triggers 15 is obtained, the highest score in any selection column on a coupon is taken and the coupon is then sorted by a flap type sorter in accordance with this highest score.
