Title: Improvements in the manufacture of ball bearings
IPC: B21K1/04
Filed: 1941-11-26
Abstract: 552,180. Making ball bearings. COLLINS, A. L. Nov. 26, 1941, No. 15255. [Classes 83 (ii) and 83 (iv)] Ball bearings, particularly those of very smal size for use in instru ments &c. have the bal races brought to finished size by pressing and rol ling in balls that are somewhat oversize, for example the balls may be 0.124 inch diameter when the running balls are to be 0.109 inch. Ir the production of an outer race 1, Fig. 1, the track or groove is pressed or turned to a larger radius and less depth than required and is finished by balls 2 that are slightly oversize that are pressed, and rolled in the track by the conical end 4 of a driven spindle. The rolling is finished when the flange shown engages the balls and such engagement causes skidding of the balls and polishing of the raceway. The race is held in a jig 3. Instead of the conical end 4, the spindle may have a cylindrical and shouldered end 7, as shown in Fig. 4, which illustrates the production of a race for a journal type bearing. An inner conical race 8, Fig. 3, for use with the race 1 is finished by mounting on the end 10 of a spindle and rolling in a ring of balls 2 mounted in a counterbored die 11. The die for the inner race of the journal bearing has a parallel bore the race being finished when the balls fully enter the bore.

Filed: 1916-10-28
Abstract: 126,025. Dawson, Sir A. T., and Buckham, Sir G. T. Oct. 28, 1916. Ordnance design; breech mechanism.- Relates to guns in which the recoil is eliminated by the rearward discharge of a compensating mass, and in which the gun is opened for loading by operating a handlever E which acts upon a movable portion B of the barrel to (1) rotate it with respect to a fixed portion A to disengage interrupted threads, (2) move it longitudinally, and (3) swing it aside about a shaft B<1> parallel to the barrel. According to the invention, the three movements are effected by continuous movement of the hand-lever E in one direction. In the form shown, this movement is converted by bevel gearing to a sleeve C rotating on the shaft B<1> and carrying an arm provided with a horizontal roller C<2> which engages with a cam groove b<2> in a member B<2> attached to the barrel portion B to rotate this portion to unlock it from the fixed barrel portion A. The sleeve also carries a second arm provided with a radial roller C<1> which first engages a cam groove b<1> in the member B<2> to move the barrel portion B rearwardly in guides b until arrested by a collar b<3>, rotation of the barrel being prevented by a key B<x> engaging a slot in the collar b, and then moves the barrel portion B laterally on to a support D<xx> as shown in Fig. 4. The barrel portion B during its swinging movement operates a cartridge extractor F, and a spring-controlled catch b<x> on moving away from a stop face d<1x> engages with a recess b<1x> in the key B<x> to lock the portion B against longitudinal movement. The handle E, Fig. 5, has a spring-controlled lever-catch e which is disengaged from a recess d<1> by pushing a sleeve E<1> inwards, but during the rotation of the handle a. screwed sleeve E<2> feathered to the handle boss retains the lever e out of engagement with the notch. The gun is provided with firing mechauism as described in Specification 126,026.

Title: Improvements in or relating to television and like systems
IPC: H04N3/04
Filed: 1933-05-29
Abstract: 401,990. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Bedford, A. V.; 118, East Palmer Avenue, Collingswood, New Jersey, U.S.A.) May 29, 1933, No. 15496. Convention date, May 28, 1932. [Classes 40 (iii) and 40 (v).] In the production of a saw-tooth current 33 for deflecting the ray 16.in a cathode-ray tube 10, a feed-back circuit 36, associated with a valve 32, compensates distortion of the wave form. Short impulses at the picture frequency, for example 24 cycles per second, are produced by a positively back-coupled valve 23, with a condenser 25 in its grid circuit, which is charged during each impulse to block the valve until the charge has leaked through a resistance 27. A network 30 in the output of the valve gives rise to a voltage wave 31, which would produce a saw-tooth wave in the output of the valve 32 in the absence of distortion due to the non- linear charging characteristic of the condenser 28, current passing through a resistance 34, distributed capacity in the output circuit, the inductive load, and the characteristic of the valve. The distortion is counteracted by negative reaction through an impedance network 36 in the cathode circuit of the valve. Other networks including an inductance shunt and a capacity shunt, or only an inductance shunt or a capacity shunt may be used, Fig. 4 (not shown). A second circuit 20 produces a similar current 40 at the line frequency. The oscillator may comprise a valve which periodically discharges a condenser, Fig. 5 (not shown).

Title: Centrifugal machines for purifying paper pulp and the like
IPC: B04B1/02
Filed: 1933-05-29
Abstract: 421,719. Centrifugal machines. BANNING, H., 101, Oberstrasse, D³ren, Rhineland, Germany. May 29, 1933, No. 15519. [Class 23] A centrifuge for purifying paper pulp and the like has one or more barrels 1 with flanges 5, 6, at its ends to retain the separated heavy impurities, and has a plate 7 which is located outside the flange 5 and acts as a dam to ensure a sufficient depth of liquid material in the barrel to permit the light impurities to ride upon the liquid. The pulp enters the drum near the wider flange 6, and the small sectional area of the purified pulp discharge passage between the flange 5 and the plate 7 enables the material to build up a considerable thickness in the drum, so that vortices do not reach the inner surface. The light impurities can be removed by a skimmer. In the modification shown in Fig. 2, the surface 7 partly encloses the drum 1 and an adjustable plate 8 on the drum enables the sectional area of the discharge opening to be varied and the stream of material to be throttled. In a further modification, the drum is enclosed by a second drum and the purified pulp passes through the space between the two drums. In the form shown in Fig. 4, the second drum 9 extends to the height of the flange 6 and forms the outlet with the adjustable plate 8. An additional drum 11 may be used in a preliminary purification to increase the capacity for holding heavy impurities. In a further modification, each end of the drum is enclosed so that the discharge path is divided into two parallel paths which join at an adjustable opening level with the centre of the drum.

Abstract: 275,761. Royce, F. H. June 24, 1926. Fluid - friction vibrationdampers. -In apparatus in which a hollow double ended piston works in a closed cylinder and in which the compression chambers at the ends of the cylinder are connected by passages provided with spring-controlled valves, the spaces available for liquid under compression vary in shape against the reaction of springs, before the valves open. The piston is reciprocated by a spindle b, liquid being drawn into the ends of the cylinder, when necessary, from a reservoir partly surrounding the cylinder a through non-return ball valves a<12> and passages a<9> connected to a filter member a<8>. A chamber is formed in one end of the piston between a diaphragm d<2> and an auxiliary piston e<1>, the position of which is controlled by an outer helical spring e<4> and an inner helical spring e<11> opposing the outer spring. The inner spring is enclosed in the tubular stem e<2> of the piston e<1> and bears against the end flange e<10> of this piston and also adjacent a nut on the end of the pin e<5> secured in the diaphragm d<2>. The piston e<1> is normally located across the centre of the thickened part d<4> of the main piston, being located in this position by the spring. When the piston moves to either side of this position, it engages the ends of the thickened part d<4>, these ends having longitudinal grooves so that liquid can then pass in either direction. Passages e<13> in the piston walls connect one end of the cylinder to the chamber at the opposite end of the main piston. During the first part of the movement of the piston in either direction from its central position, the auxiliary piston e<1> remains stationary, this movement being only resisted by the spring e<4>, e<11>. Further movement of the main piston results in flow of liquid past the piston e<1> through the grooves in the thickened part d<4>.
