Title: Improvements in or relating to spacing collars and the like for mounting cutters on shafts, or for other purposes
IPC: B23Q17/22
Filed: 1934-01-20
Abstract: 419,907. Washes. ROBERTS, BLACK, & CO., Ltd., and ANDERSON, F. G., 37A, Bridge Street, Manchester. Jan. 20, 1934, No. 2025. [Class 89 (i).] An adjustable spacing collar for spacing a gang of milling cutters along a spindle or for other purposes comprises two ring portions a, h, which are slidably but non-rotatably connected independently of the spindle and an adjusting-ring which screws over one or both of the other rings to vary the spacing thereof. The ring a is slotted at c for keying to a milling spindle &c. and is provided with spaced bores f which receive pins l secured to the second ring h, the latter having a key slot j aligned with the slot c. The two rings are resiliently secured together in an axial direction by screws g screwing into ring a and bearing through compression springs m against seating in the ring h. Adjustment of the spacing assembly is effected by a third ring r screwing over square threads e on the ring a. The engaging faces s between the adjusting ring and the ring h may be serrated and the adjustment is indicated by a scale on the adjusting ring coacting with an index mark q on the ring h. When fitted the rings are set so that adjustment in either direction is possible. In a modification, Fig. 5, the ring is provided with an annular recess 6 to receive the end of the threaded ring 11 over which is screwed an adjusting ring 21 having a graduated periphery. In another modification the adjusting ring may be screwed over both the other rings by threads of different pitch or hand.

Title: Improvements in or relating to modulating circuit arrangements for high frequency magnetron oscillators
IPC: H03C1/30
Filed: 1938-01-21
Abstract: 506,439. Valve modulating circuits. SIEMENS & HALSKE AKT.-GES. Jan. 21, 1938, No. 2098. Convention date, Jan. 21, 1937. [Class 40 (v)] A high-frequency magnetron generator is substantially fully modulated without causing cessation of oscillation by applying to two anodes or anode groups different D.C. potentials and varying them in opposite directions by means of the modulation, so that the slope of the negative part of the characteristic which corresponds to high frequency operation remains unchanged. The anode segments 22, 23 receive different positive voltages with respect to the cathode 28 from batteries 24, 25 through chokes 26, 27 ; and modulating potentials are applied from a source 33 in push-pull to the anode segments by means of a transformer 31. In other arrangements, Figs. 9, 10 (not shown), batteries 24, 25 are replaced by arrangements of batteries with tappings. The same results may also be obtained by simultaneously varying several electrical values. Thus the anode current can be varied by modulating the total emission current, and the change in 'slope of the negative resistance characteristic can be compensated by simultaneous variation of the magnetic field, or the total anode voltage, or one segment voltage.

Abstract: 892,910. Cis -1,4 polybutadiene/vinyl aromatic blends. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Jan. 23, 1961 [Jan. 25, 1960], No. 2592/61. Class 2(6) A moulding composition comprises 80-98 % by weight of one or more polymerized vinylaromatic compounds and from 20-2 % by weight of a polybutadiene containing at least 90% of cis -1,4 units. The vinyl aromatic compound may by styrene vinyl toluene, vinyl xylene, vinyl ethyl benzene or vinyl chlorobenzene. The composition may be made by mechanically mixing the two homopolymer components in an internal mixer or on a two-roll mill. Alternatively the blending may be effected by graft polymerization of vinyl aromatic monomer on to preformed cis-1,4 polybutadiene. Polymerization may be carried out in bulk using heat, peroxides, ionising radiation or a combination of heat and peroxides as initiator. All agitation should be avoided after 12% conversion. Suspension techniques may also be used whereby a solution of butadiene polymer in the monomer is dispersed in water in the presence of a suitable stabilizer such as polyvinyl alcohol, gelatine, bentonite, calcium phosphate or oxalate, barium sulphate, sodium carboxy-methyl cellulose, copolymers of ethylene and maleic anhydride and polyethylene ether glycols. A catalyst such as an azo compound or a peroxide may be added and also a very small percentage of a surface active agent. About 1-6% of a lubricant such as paraffin wax or a white mineral oil may be added before polymerization. Polymer particles may be separated by the usual techniques. A mixed bulk/ suspension process may be used whereby bulk polymerization is carried out to 40% conversion and then continued by suspension. Inert ingredients such as fillers and antioxidants for polystyrene may be added.

In Fig. 1 the impeller C is mounted in a recess in a false wall I of the container and liquid is caused to follow the path indicated by the arrows, being ejected through the outlet G in a conical and spiral path. The impeller is provided with radial ribs L on its front face and a number of centrifugal pump blades E on its rear face. The ribs and blades may be produced by stamping, a rib on the front of the impeller forming the space between two blades on the back. In Fig. 5 the impeller is in a cup shaped recess in the side wall of the container and the liquid is circulated by the pump blades through a screened opening in the base and a connecting tube K. In Fig. 9 the impeller is perforated around its centre and the liquid circulates through the perforations, between the blades E and out through the outlet G.
