Title: Improvements in Electric Current Controllers.
Inventor: UCHIDA YOHTARO
IPC: H01H71/12
Filed: 1918-02-12
Abstract: 123,148. Uchida, Y. Feb. 12, 1918. Electro - magnetic switches; contacts; indicators. - Magnetic material, such as iron wire, is contained in a float 8 carrying a forked contact 10 which normally bridges mercury contacts 3, 3<1> at the bottom of a vessel 1 containing oil. When the current through the main coil 11 exceeds a determined amount, the float moves into the position shown in dotted lines, thereby bringing a highresistance auxiliary winding 11<1> and an additional resistance 12 into series with the main winding. The windings 11, 11<1> retain the float in its upper position until the circuit is opened. A mass of cotton or like material 15 prevents the float from being broken by the sudden movement of the iron. The resistance 12 may be replaced by a lamp, which indicates operation of the switch. A discharge pipe 6 enables gas to escape, and a check-plate 13<1> prevents excessive movement of the float.

Title: Telegraphic transmission systems
IPC: H04L1/18
Filed: 1972-01-20
Abstract: 1350364 Digital data transmission systems SIEMENS AG 20 Jan 1972 [21 Jan 1971] 2709/72 Heading H4P In a data transmission system where received characters are automatically returned to the transmitter for comparison with the transmitted data, the transmitter includes an intermediate store between the receiving register and the register from which comparison is made, so that characters which are received irregularly spaced through the variations in the loop transit time do not overwrite themselves. In the arrangement disclosed call or synchronizing signals TA are sent to a subscriber calling for, or timing the return of received characters which are returned in a 5-bit start-stop code into register SR. Circuit TSR scans the centre of each bit to develop a bit signal El, which clock the character into register SR, and a stop bit signal E2, to develop via AND gate U1 a signal A1 in synchronism with the stop bit, which after a delay (V1) passes through AND gate U2 to produce a restore signal T2 to transfer the respective character from register SR to an intermediate store Z1. The delayed pulse also resets bi-stable K1 to its Q2 output, thereby inhibiting AND gate U2 and preventing any further read-in to store Z1. Under normal circumstances the store pulse T3, having a fixed phase to the corresponding call pulse TA, now reads the character in store Z 1 into the first store SZ of the comparison store SP and resets bi-stable K1 to permit readin of another character into store Z1. If a character arrives late so that a T2 signal occurs after a T3 signal the T3 signal reads in a blank character, and resets the Q1 output of bi-stable K1. The T2 signal of the late arriving character can now be generated and reads in its character into intermediate store Z1, K1 bistable being set to its Q2 output simultaneously. The following character now arriving at the correct time cannot be read into the intermediate store Z1 because AND gate U2, inhibited by bi-stable K1, locks the T2 read-in pulse, but it does set via gate U3 the Q3 output of the bistable K2. The T3 pulse of this last mentioned character now transfers the late character in Z1 store into store SZ and also sets the Q1 and Q4 output of bi-stables K1 and K2. The pulse appearing at Q 3 output of bi-stable K2 after being delayed (V2) reads in the last character into store SZ and resets the Q2 output of bi-stable K1. Thus the overwriting of the late arriving character by the following one is prevented.

Title: Improvements in or relating to processes for immunizing threads
IPC: D06P1/673
Filed: 1929-01-26
Abstract: 325,961. Chemical Works, formerly Sandoz. Oct. 22, 1928, [Convention date]. Yarns &c., treating with liquids.-Threads of vegetable fibres such as cotton and regenerated cellulose (nitro, cuprammonium, and viscose) and the like are immunized against the usual cotton dyes such as substantive dyes, vat dyes, sulphur dyes, and the like in package form as cops, cones, cakes, cheeses, warp threads on beams, and the like, thus eliminating the unwinding and rewinding operations and reducing the amount of shrinkage usually associated with these immunizing operations. The process consists of treating the package first in an alkaline bath made up of caustic soda, potash, or ammonia dissolved in either water or 95 per cent alcohol, the solution containing also pyridine, turkey red oil, soap or the like. After the thread surface has been alkalized, the excess of alkali is removed in a centrifuge or by other suitable means, and the packages are then mounted in a machine wherein an esterifying agent in solution is applied under pressure to the package. As esterifying agents may be used a carboxylic acid chloride such as benzoyl chloride or a sulpho-chloride such as paratoluol - sulpho - chloride, benzo-sulpho-chloride, ortho-toluol-sulpho-chloride, xylol- and naphthalene sulpho-chlorides or the chlorine, bromine, and nitro-derivatives of all these compounds. Inorganic acid chlorides such as phosphorus trichloride can also be used. As solvents, carbon tetrachloride or other chlorinated hydrocarbons of the fatty series, benzoyl and its homologues, may be used and solutions containing 20 per cent of the reagent are suitable. The excess of esterifying agent is removed by centrifuge or the like, and the package is washed with soap solution under pressure in the same machine, centrifuged, and dried.

Title: Improvements relating to stereophonic transmission systems and receivers therefor

IPC: H04H20/88
Filed: 1961-01-26
Abstract: 1,012,160. Stereophonic transmission systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 26, 1962 [Jan. 26, 1961], No. 3081/61. Heading H4R. In a stereophonic transmission system in which two audio signals representative respectively of the sum and difference of two further audio signals which are derived from a sound source and which differ one from another in dependence upon the direction or position of said source, the difference signal is subjected to amplitude compression before it is actually transmitted. Rising transients occurring in the envelope of the sum signal may also be compressed. It is stated that by these means the bandwidth (in a frequency modulation transmission system) allotted to the sum signal may be increased without degrading the difference signal which carries the stereo information. Signals derived from left and right microphones 1, 1<SP>1</SP> are combined in circuits 2, 3, part of the sum signal then being passed via a delay network 21 to an amplifier 22 and part being passed via circuits 18, 19, 20 so as to produce a signal which controls amplifier 22 whereby amplitude compression of transients in the sum signal is obtained. A filter responsive to transients is depicted in Fig. 3 (not shown). The difference signal is treated in a similar manner but in this case the circuit 7 (Fig. 2, not shown) takes the form of a low-pass filter which controls the rise and fall times of the envelope of the difference signal as derived by rectifier 6. A receiver for the above system is described with reference to Fig. 4 (not shown) in which receiver the difference signal only is expanded before being combined with the sum signal so as to produce a stereophonic output.
