Inventor: ZEHAVI EPRAIM
IPC: H04W88/14

Abstract: Method and apparatus for generating orthogonally encoded communication signals for communication system subscribers using multiple orthogonal functions for each orthogonal communication channel. Digital data symbols for signal recipients are M-ary modulated using at least two n-length orthogonal modulation symbols, which are generally Walsh functions normally used within the communication system. These symbols are provided by a modulation symbol selector (124) typically from one or more code generators (126, 128), and the modulation is such that M equals a product of a total number of orthogonal functions and the number used to generate individual modulation symbols. Each group of log M encoded data symbols from data processing elements (100, 102) are mapped into one modulation symbol using the modulation symbol selection element (124) according to their binary values. In some embodiments, a fast Hadamard transformer is used for symbol mapping. The resulting communication signals are demodulated by correlating them with the preselected number of orthogonal functions, in parallel, and demodulating the results into M energy values representing each orthogonal modulation symbol. The energy values are mapped into energy metric data using a dual maximum metric generation process. The correlation and demodulation can be accomplished using at least two sets of N correlators (142), N being the number of functions used, and applying correlated signals to one demodulator for each set of correlators (144). Each demodulator outputs M energy values representing each of the M mutually orthogonal modulation symbols, which are then combined into a single set of M energy values. In further configurations, coherent demodulators (172, 174) can be used to produce amplitude values for received signals which are then combined (178) with dual maximum metric results (170) to produce composite metric values for data symbols (178).

Abstract: 737,590. Electricity supply systems; starting prime movers. ROTAX, Ltd. Jan. 8, 1954 [Jan. 14, 1953], No. 1081/53. Class 38 (4). In generating plant comprising an engine-driven generator a-c provided with a carbon pile regulator e, f in its shunt field b for automatic voltage or current control, and wherein for starting the engine the generator is used as a motor, supplied from, say, a battery d, the regulator is disabled during starting of the engine by a further winding g of the regulator which becomes energized over a rectifier h by, say, the voltage drop across the series field coil a of the machine and nullifies the effect of the winding f. Due to the.reversal of current flow through the series field coil r when the machine is generating, the rectifier h prevents energization of the winding g so that the regulator functions normally. In a current-regulated system, the winding f is in series with the generator and battery and is shunted by the series combination of the rectifier h and winding g.

Filed: 1920-01-13
Abstract: 163,085. Clorius, A. V., and Clorius, O. T. Jan. 13, 1920. Thermostats.-Relates to thermostats of the type in which a liquid enclosed in a reservoir i, Fig. 1, is adapted, on expanding, to act upon a currugated flexible membrane f or upon a piston so as to control the movements of a valve b regulating the heating- apparatus of a building &c. According to the invention, the reservoir i is provided with a piston p, the position of which in the reservoir is adjustable by means of a screw s and a spring t, the initial tension of the spring being greater than the friction of the piston against a washer o, and the piston serving to fill the apparatus and to act as safety member against accidental overheating. The washer c is held in place, by a closure q so as to form a water-tight joint with the piston p, and the screw s preferably engages an opening in one of the removable supports l of the apparatus. The piston in the construction shown in Fig. 1 is hollow and provided at its lower end with lateral openings u so that the apparatus can be filled by removing the support l and withdrawing the piston until some of the openings u come above the washer o. When the apparatus is in operation any accidental overheating after the valve b has closed causes the piston p to be driven upwardly against the action of the spring t, and in exceptional cases the openings u may finally come above the washer o and permit a leakage of the liquid. The temperature at which the valve b closes may be varied by adjusting the initial position of the piston by the screw s. In a modification, a solid piston is employed and during its insertion in the reservoir leakage is permitted between it and the washer o, which is arranged between two discs so that it can subsequently be compressed to form a tight joint upon the piston. The spring is arranged either between the top of the piston and a screw-cap for tightening up the washer anc. adjusting the piston, or between a disc at the lower end of the piston and the lower disc for the washer. In a further modification Fig. 5, the piston 61, instead of being arranged in the reservoir i directly is arranged in a a cylinder 69 connected to tthe reservoir and replacing the membrane f, the piston being adapted to move so as first to actuate to the valve b, and then to compress a spring 71 to compensate for overheating.

Title: Improvements to electrically driven clocks

Abstract: 395,695. Electric clocks. STEVENS, E. H., 49, Ashworth Lane, Astley Bridge, Bolton. Jan. 18, 1932, No. 1400. [Class 139.] An electric clock driven directly by an alternating current synchronous motor, has means for driving the clock motor, or another motor, by intermittent direct current when the A.C. supply fails. The rotor b, driving the clock mechanism, is normally actuated by the winding c on stator a fed from an A.C. supply, which also energizes a coil j to hold the blade f, h away from contact i. When the A.C. supply fails, contacts h, i close and a battery e energizes a winding d to drive rotor b. The interrupter blade f is vibrated by the flux of the stator magnet, at a frequency suitable to move the rotor b at the normal speed. In the arrangement of Fig. 2 the A.C. energizes motor winding a and a coil l which maintains a switch k open. d is the motor winding fed with D.C. from battery e. The latter is charged from the A.C. supply through transformer m and valve n. Coil o vibrates the blade f of interrupter contacts h, i. When the A.C. fails, switch k closes and the battery feeds the winding d with intermittent D.C. of the correct frequency, a coil p in series with the winding d vibrating the blade f. Coils o, p may be omitted and the motor windings may be used to vibrate the contacts h, i. The motor may have a single winding which normally receives A.C. but may receive the intermittent D.C. Alternatively, two separate motors may be used. In another modification, a transformer may be interposed between the D.C. and the field winding so that intermittent D.C. causes A.C. to be supplied to the motor.

Abstract: Textile materials are dyed from an acid bath with an o,o1-dioxymonoazo dyestuff which is suitable for dyeing from a neutral or weakly alkaline, but not from an acid bath, in the presence of an o,o1-dioxymonoazo dyestuff which per se is suitable for dyeing from an acid bath.  Suitable dyestuffs of the first type are those which are free from sulphonic acid and carboxyl groups and have the general formula HO-R1-N=N-R2-OH, in which R1 indicates an aromatic residue of the benzene series and R2 the residue of a coupling component such that the two OH- groups are in adjacent position to the azo group, and the whole dyestuff molecule may contain a single sulphonamide group.  Other dyestuffs of the first type are free from sulphonic acid and carboxyl groups and have the general formula <FORM:0671243/IV (c)/1> in which R1 is a residue of the benzene series in which the azo group and the hydroxyl group are in o-position to each other, R3 is a phenyl residue and the whole dyestuff molecule contains a single sulphonamide group.  The mixture of dyestuffs may be used according to the single-bath chroming process or the after-chroming process.  In examples: (1) wool is dyed with a mixture of the following dyestuffs, of which the first two are of the first type referred to above <FORM:0671243/IV (c)/2> <FORM:0671243/IV (c)/3> <FORM:0671243/IV (c)/4> -with the addition of sodium sulphate and acetic acid, and after cooling the dyeing is chromed by adding potassium dichromate to the bath; (2) wool is dyed with a mixture of dyestuffs consisting of the first two dyestuffs of the previous example together with the dyestuff <FORM:0671243/IV (c)/5> and chromed as before.
