Title: Improvements in or relating to balancing arrangements for use in telephonic and likeconnections
IPC: H04B1/58
Filed: 1924-09-19
Abstract: 222,852. Siemens & Halske Akt.-Ges. Oct. 6, 1923, [Convention date]. Duplex signalling. - At the junction of a two-wire line A with a four-wire line B, C in which a balancing network K is employed, the frequencies for which the impedances of the line A and the network K are not quite equal are cut out by means of a filter circuit comprising parallel impedances R, W in series with the halves of the secondary of the transformer U, the impedances being approximatelv equal for these frequencies and differing considerably for other frequencies. The assumption is made that the transmission is not affected by the elimination of these frequencies, which are generally those above the natural frequency of the line A. The impedance R may be a capacity, and the impedance W an inductance and capacity in parallel, and better results may be obtained by the addition of resistances in series or in parallel. The invention is also applicable to balancing or equalizing connections for high frequency telephony.

IPC: H02P25/32
Filed: 1959-06-30
Abstract: 920,259. Control of A.C. motors. M. TESSIE-SOLIER, and C. CURIE. June 30, 1969, No. 22503/59. Class 38 (3). [Also in Group XXXV] The rotor windings of an induction motor 34 are connected to a rectifier 35 having output lines 31, 32, connected to an inverter 11-13 which is coupled to source 1, 2, 3 through transformer 4 and which is controlled in accordance with the speed and torque of the motor. A speed-measuring voltage is applied to potentiometes 39 and is compared with a reference voltage from potentiometer 41, the error signal being applied to the grid of valve 24. The cathode of this valve is returned to earth through potentiometer 21 which introduces a rotor current (or torque) measuring signal in addition to the speedresponsive signal. The combined signal is amplified to control valve 45 having cathode load resistor 46. The control signal for the inverter 11-13 are developed across lines 29, 30 and is equal to the difference between the currents delivered by valves 45, 47, the latter having a cathode resistor 48 and having its bias adjusted by reference potentiometer 49. Current transformers 8-10 provide a torque-measuring voltage to potentiometers 21, 22, a valve 23 acting as a torque-limiter in accordance with the adjustment of potentiometer 25. In another arrangement, the rotor frequency provides an indication of the speed of the motor independent of the load. A signal derived from a transformer in the rotor circuit is passed through a filter circuit to two clipper stages. The amplified signal is then transmitted to an integrating circuit by a differentiating network, the direct-current output of the integrator being associated with the frequency of the pulses supplied thereto and representing the motor speed, Fig. 3 (not shown). The motor may be operated with a constant power characteristic. The power returned to the mains may be controlled when the motor operates as an electrodynamic brake.

Title: Improvements in or relating to the preparation of sheet materials incorporating alkylene polymers
Inventor: KEYSER LODEWYK FELIX DE
IPC: C08J7/14
Filed: 1958-07-14
Abstract: 910,308. Photographic materials and processes. GEVAERT PHOTO-PRODUCTEN N.V. July 14, 1959 [July 14, 1958], No. 22508/58. Class 98 (2). [Also in Group VIII] A photographic sheet material is prepared by treating a high polymeric polyalkylene sheet or film with a solution containing sulphuric acid and a substance which in the presence of this acid acts as an oxidizing agent, rinsing the sheet or film free of acid solution and applying a hydrophilic photographic subbing layer which may comprise gelatin and another macromolecular compound or compounds to the sheet or film before it is completely dry. The material may be used in a silver halide diffusion transfer process. One or more layers which directly or indirectly utilize the action of light to bring about the formation of an image, e.g. a gelatino silver halide emulsion, may be applied to the sheet material. The sheet or film may be first rinsed with water and superfluous water then removed, mechanically or by means of an organic solvent, before the application of the hydrophilic layer. The polyalkylene sheet or film may be of a polymer of lower straight alkenes, polymers of branched alkylenes or mixtures of different alkylene polymers, e.g. polyethylene, polypropylene, which may be oriented and isotactic, poly-n-butylene, polyisobutylene, polypentane, poly-3-methyl-1-butene, poly - 4 - dimethyl - 1 - pentene, and vinyl cyclohexene, which may be stretched and stabilized. The sheet or film may be supported at the time of application of the hydrophilic layer, or may subsequently be united with a support, e.g. paper. Suitable oxidizing agents are chromic acid anhydride and alkali metal bichromate or permanganates. The oxidation may be carried out in the presence of other substances, e.g. organic acid such as acetic acid which favourably influences the adhesive power of the sheet. Macromolecular compounds specified are cellulose nitrate, acetate, acetocarbamate, and acetophthalate, alginyl nitrate, styrene-acrylic acid copolymer, polystyrene sulphonic acid, styrene-maleic acid copolymer, polypropylene and polynitrostyrene. Specifications 738,471, 755,738, 758,461, 804,058, 839,701, 851,727 and 854,649 are referred to.

Title: Improvements in or relating to apparatus for indicating road traffic conditions
Inventor: PARKER ERIC
IPC: G08G1/01
Filed: 1964-06-01
Abstract: 1,066,473. Road traffic measurements. DECCA Ltd. Sept. 1, 1965 [June 1, 1964], No. 22646/64. Heading G4Q. A traffic jam is detected by processing signals from a vehicle presence detector to give outputs corresponding to traffic density and to vehicle interval, an alarm being given when both rise above a predetermined level. The presence detector VD operates a relay A so long as a vehicle is present; when the relay is operated its contact A1 allows capacitor C1 to charge over resistance R1, and when the relay is not operated C1 discharges through resistance R2. The voltage on C1 corresponds to traffic density and is compared with a reference potential in comparator DC. The output from detector VD also passes via a capacitor C to a relay B in parallel with a rectifier, the arrangement being such that relay B operates momentarily when a vehicle enters or leaves the detection zone according to the polarity of the rectifier. Operation of relay contact B1 discharges a capacitor C2 which normally charges through a resistance R3, so the voltage on C2 is proportional to the interval between vehicles and is compared with a reference potential in comparator IC. The comparators operate respective relays C and D, contacts C2 and D2 of which are arranged in series in an indicator or alarm circuit which may light a lamp on a chart. Further contacts C1 and D1 in series maintain the charge on capacitor C1 until the alarm circuit is broken by a vehicle entering or leaving the detection zone and thereby operating relay B. In a modification capacitor C1 is continuously connected to a discharge resistance.

Abstract: 800,804. Selective punching machines. COMPAGNIE DES MACHINES BULL. July 23, 1956 [Aug. 2, 1955], No. 22763/56. Class 31 (2). [Also in Groups XVI, XIX and XXXVII] The invention relates to electric switch mechanism actuated by the tabulating movement of the carriage of a tape punching machine, whereby predetermined control circuits are closed in different positions of the carriage. Such apparatus may comprise an insulating panel 1, Figs. 1 and 4, secured to the carriage 4 and provided with columns of contacts 1C, 2C, 3C, &c. adapted to engage successively a single column of wiper contacts BA-BH secured to the machine framework. Selected adjacent contacts of a column are interconnected, as at 7, and the panel of contacts is removable from the machine carriage; and interchangeable for others having alternative patterns of interconnections. According to the invention, the interconnections 7 are formed by deposits of conducting material, e.g. a conducting ink or soft solder. The contacts themselves may be printed on the panel 1 and set flush with the panel surface by embedding them in thermoplastic material of the panel by the application of heat and pressure. Cavities may be formed in the panel for the reception of. the interconnecting material 7, so that this will not be liable to damage in handling. In changing the panel, the machine carriage is moved to the extreme right, whereupon a lever 16, Fig. 6, is rocked by abutment with the frame 15 and releases a catch 22 normally retaining the panel in position. The arrangement of contacts 2 may be varied from that shown in Fig. 1; alternate rows A-H may be replaced by continuous strips ; or groups of adjacent columns may be associated with tabular positions of the carriage, the column of wiper contacts BA-BH being supplemented by further adjacent wiper contacts. Modified forms of the apparatus are described in which the panel 1 is replaced by a rotatable disc or drum, carried by the machine framework and driven by the carriage. The contacts may be disposed in concentric rings, or arranged in a spiral or helically. Fig. 15, for example, shows a construction with wiper contacts 65 traversed over helically arranged contacts 61, 62 on a rotatable drum 63 by means of a screw-and-nut mechanism 64.
