Title: Improvements in and relating to self energising disc brakes
IPC: F16D55/224
Filed: 1963-06-26
Abstract: 1,021,154. Disc brakes. F. J. C. HOPE. June 5, 1964 [June 26, 1963], No. 25486/63. Heading F2E. In a disc brake of the kind in which a camoperated master disc brake means 3 is adapted to engage the radial sides of a brake disc and is effective under a force generated by the frictional drag of the rotating disc to bring into braking operation cam-operated slave disc brake means 6, the operation of the slave brake means 6 is effected by a V-cam 5 mounted on a torque arm 4 associated with the master brake structure and rotatable about the axle, the V-cam having a convex profile to co-operate with a cam follower 8 associated with the slave brake operating means so as to cause the slave brake means to operate when the master brake is actuated. One construction of the V-cam (Fig. 2, not shown) provides a seating position in the apex of the V to receive the cam follower 9 when in the inoperative position. An alternative construction of the cam (Fig. 3, not shown) provides that each half profile of the V-cam has a linear lower section profile 12 and a convexly curved upper section 13. In operation, actuation of the master brake caliper 3 through a compressed air operated cylinder 1 and a cam operating arm 2 causes the caliper to be actuated. The frictional torque applied to the master brake caliper due to the rotation of the disc 10 causes rotation of the caliper 3 and the associated torque arm 4 about the axle 15 and corresponding movement of the V-cams 5 takes place and the cam followers 9 rise on their cam profiles. Arcuate movement of the servo brake operating arms 8 takes place and the slave calipers 6 are operated to apply a supplementary braking effect on the disc 10.

Patent GB-256663-A (GB)
Abstract: 256,663. Dreyfus, H. April 9, 1925. Acetic anhydride is prepared by subjecting acetic acid vapour to the action of heat and immediately submitting the products to fractional condensation to separate the anhydride and water formed. The fractional condensation may be effected by passing the hot vapours through a fractionating column or columns. Preferably, both the reaction and the fractionation are carried out under reduced pressure. Catalytic materials may be present, e.g. sodium sulphate, calcium sulphate, or the materials specified in Specification 257,968, mixed if desired with an inert material. The reaction temperature extends from 200- 1000‹ C.; the speed and passage of the vapours should not be so low as to incur decomposition into gaseous products; and the material surrounding the hot reaction zone is preferably made of copper, though earthenware &c. may be used.

Title: Improvements relating to x-radiation analysis
Inventor: WITTY ROY
IPC: G01N23/225
Filed: 1962-07-04
Abstract: 998,196. X-ray analysis. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and E. COHEN. July 8, 1963 [July 4, 1962], No. 25673/62. Heading G1A. [Also in Division H1] A liquid suspension of a specimen material required to be analysed is introduced into a hollow cell 5 arranged to constitute with the suspension a composite X-ray tube target such that on energization of the X-ray tube the specimen material in the cell 5 is excited to emit characteristic X-radiation, said radiation being analysed to obtain an analysis of the specimen material. In the arrangement shown the specimen fluid flows into and out of the cell 5 through pipes 6 and 7 respectively and is irradiated by an electron beam 4 from a tube 1 having a filament 2 and a cathode 3. The resulting characteristic X- radiation from the specimen material is analysed by a spectrometer consisting of a collimator 10, a rotatable analysing crystal 11, and a detector 12 which may be rotated about the crystal 11 so that it may be moved to angular positions at which radiation reflection takes place. Alternatively, the detector may consist of a scintillation or proportional counter used in conjunction with a pulse height analyser. In a preferred form the window 8 of the cell 5 may have a layer of a heavier target material such as gold which will produce primary X-rays to excit the specimen material. The layer is so chosen that its own characteristic radiation would not mask that of the specimen. The layer on the window may be discontinuous e.g. in the form of a grid having parallel strip formation (Fig. 4a not shown)

Abstract: 1,183,941. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 2 June, 1967 [2 June. 1966]. No. 25690/67. Heading H4K. A lock-out arrangement for connecting one of a group of apparatus units to an idle one of a second group of units comprises two sets of bi-stable devices which provide " tree " connections between wires individual to the units of each group and a common point. The bistable devices may be 2-winding polarized relays or equivalent electronic circuits. In Fig. 1, one of a number of registers REGL storing a wanted number is connected to an idle one of 4 markers M41 over a cross-bar switch RSM under the control of common equipment RMM comprising two sets of bistable relays. Relay RR1 in the calling register REGL closes a circuit to relay MR3 in the first idle marker, assumed to be MH1, through the relevant relay windings, and these complete a circuit for MR2 in series with select magnet SM1, whereupon operating BM establishes the cross-bar connection. MR1 energizes in series with RR2 and the common equipment is released. A pulse on wire a causes the transfer over the stored number over common wires t 1  . . . t m  to a marker store MR. A faulty marker is put out of service by alarm relay AL, and a thermal contact r 1  becomes operative if RR2 fails to pull up. A similar arrangement employing electronic circuits is described with reference to Fig. 2 (not shown). A similar lock-out arrangement, Fig. 3 (not shown), serves to connect a marker to an idle junction in a selected traffic route, the identity of the junction being signalled from its line circuit to the marker for the purpose of establishing the connection. There is provision for preventing the repeated selection of the same faulty junction.

Title: Improvements in or relating to the manufacture of artificial silk threads, filamentsand the like
IPC: D01F2/12
Filed: 1933-09-22
Abstract: Artificial silk threads or filaments of a matt finish or dull lustre are produced by incorporating in the spinning solution dibenzyl ether, or a halogen derivative thereof.  A wetting or emulsifying agent may be added, e.g. sulphonated fatty alcohols or acids.  There is preferably also added a mutual solvent for the dibenzyl ether and the spinning solution, e.g. ethyl alcohol, which is added to the dibenzyl ether or halogen derivative before dispersion in the spinning solution.  In an example, dibenzyl ether is mixed with 25 per cent of its weight of sulphonated lauryl alcohol, and the mixture incorporated with viscose so that the final content of the dibenzyl ether is 6 per cent of the cellulose content of the viscose; the incorporation is preferably effected with a high speed mixing device such as a colloid mill; the emulsion is then spun.  In a further example, dibenzyl ether or a chlor-derivative thereof is agitated with 10--20 per cent of its weight of sulphonated ricinoleic acid, and the mixture incorporated in a viscose solution as in the first example.
