Title: Improvements relating to differential phase telegraph modulation
IPC: H04L27/20
Filed: 1965-05-07
Abstract: 1,105,448. Data transmission systems. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS 7 May, 1965 [12 May, 1964], No. 19483/65 Heading H4P Binary data is transmitted by phase shift, bit-pairs AZ and AA being represented by phase changes of #/2 and #, respectively, and intermediate Z bits by no phase change. The transmitter circuit, described with reference to Fig. 1 (not shown) comprises means to select input bits in a sequence of bit pairs, except that any Z bit which would start such a pair is set aside, the next bit then beginning a new sequence of bit pairs. A gating arrangement fed by the bit pairs, the isolated Z bits, and carrier develops phase shift signals as detailed above: each bit-pair occupies 1¢ carrier cycles. At the receiver. Fig. 3, the signals are sampled twelve times in each bit-pair duration, the samples passing to a 13-cell shift register 23 stepped at sampling rate. The first and thirteenth cells feed an exclusive OR circuit 24, giving an output m. By inversion at 25 m is obtained and, after removal of spurious faulty samples by majority decision at 26 as described in Specification 1,105,447, #m passes to a 3-cell register 28. The outputs #m and #m<SP>1</SP> of the first and third cells pass to gates 29, 30, giving #m#m<SP>1</SP> and #m+#m<SP>1</SP>. These signals trigger flipflops 31, 32 which give pulses of bit-pair and half bit-pair duration which feed an OR gate 33 whose output corresponds to the original binary data.

Title: Improvements in and relating to the production of aromatic sulphonic acids
IPC: C07C303/22
Filed: 1923-08-03
Abstract: Aromatic sulphonic acids having halogens in the aromatic nucleus have their halogen atoms replaced by hydrogen atoms by treatment with hydrogen in aqueous alkaline solution in the presence of an hydrogenizing catalyst.  The aromatic nucleus may be benzene, naphthalene, anthracene, &c., and other groups, such as alkyl, hydroxy, nitro and amino groups, may be present therein. The hydrogen may or may not be under pressure, and temperatures of 20-800 DEG  C. are employed.  Suitable catalysts are nickel, cobalt, copper, platinum and palladium, and the metal may be deposited in colloidal form on carriers such as kieselguhr or calcium carbonate.  For producing the alkaline solution, hydroxides or carbonates of the alkali or alkaline earth metals are used. Examples are given of thedehalogenation of p-brombenzene sulphonic acid, 2-chlor-p-cymene-3-sulphonic acid and 2-brom-p-cymene-3-sulphonic acid using a nickel or palladium catalyst and hydrogen under a pressure of 10-30 atmospheres.  The Specification, as open to inspection under Sect. 91 (3) (a) describes also the dehalogenation of 2-brom-p-cymene-3-sulphonic acid by treatment with hydrogen at ordinary pressure for several days in presence of a nickel catalyst. This subject-matter does not appear in the Specification as accepted.

Inventor: GLADWIN HAROLD BRUCE
IPC: B28B23/04
Filed: 1949-07-29
Abstract: 672,725. Prestressed reinforced concrete. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 31, 1950 [July 29, 1949], No. 20006/49. Class 20(iv) In the production of prestressed reinforced concrete the wire reinforcement 9 is gripped by wedges 10 fitting in coacting holes 8 in anchor plates 6, 7, the anchor plates are arranged between the end walls 2, 3 of the mould 1, and tension is applied to the plates by means of bars or the like 4, 5, detachably secured to the plates and extending through the end walls. of the mould, the anchor plates being cast permanently in the concrete. The wires are preferably cut so that they extend beyond plates 6, 7, but fall short of the ends of the mould so that end corrosion is prevented, but the wires act as normal reinforcement at the ends. The wires are preferably overtensioned by about 5 per cent before being placed in the mould to lessen the liability to creep. As shown, the rods 4 and 5 screw into plates 6 and 7 but may be otherwise attached, and rod 5 is anchored by a nut 11 at the end wall 3 while rod 4 is secured to a cross-bar 13 of a hydraulic ram system 14 which is anchored to a yoke 16 engaging the end wall 2. When the desired tension has been applied the rod 4 is secured by screwing up nut 15 so that it contacts wall 2, and the concrete is cast. When the concrete is cured rods 4 and 5 are removed and the holes grouted. Alternatively bars 4 and 5 may be connected between a hydraulic ram system and an anchorage which are fixed relatively to each other, e.g. to the floor, so that the stress is not applied to the mould. Specification 642,360 is referred to.

[Class 39 (i)] A Braun tube comprises a neck part 2 of substantially the same length as the electrode system and a bulb having spherical end parts 1, 3 and a cylindrical intermediate part 11, whose least diameter is 30 cm. The height a of the spherical part 3 from the end of the cylinder 11 is from 7 to 12 cm. for a cylinder diameter of 30 to 34 cm. The electrode system for a gas filled tube being shorter than that of a high vacuum tube, the neck 2 for the first type is made shorter than for the second type. A tube for either type may be made from a common stock ; part of the neck may be cut off, and if the bulb is too long, part may be removed by rotating the tube, scoring along lines at AB and BC and submitting the tube to a sudden rise of temperature. The parts are fused together again after the screen 6 has been. mounted in position. This may be effected by phosphor bronze mounts 7 held by spring members 8 received by a recess in the bulb ; or the screen may be held by one or two spring rings which grip the plain surface of the cylindrical part 11.
