Filed: 1922-10-25
Abstract: 208,303. Electrical Improvements, Ltd., Leeson, B. H., and Biles, R. W. Oct. 25, 1922. Cut-out systems for distribution networks, of the kind in which opposed electromotive forces having a frequency different from that of the main supply are superimposed upon the conductors of the system and, in the event of fault, the superimposed voltages act through tuned relays to trip the circuit-breakers, have the superimposed voltage derived from the main current itself through transformers by means of a frequencychanger driven from the main circuit, by means of a vibrating member such as a tuning fork energized from the main circuit or by means of an oscillatory circuit or an ionic transformer in the main circuit. In the arrangement shown in Fig. 1, the synchronous motor A is supplied from the transformer C on the main supply lines D drives the frequency changer E which is supplied with normal line frequency from the transformer F and supplies other windings on the transformers F with a different frequency which is superimposed on the lines. This arrangement is duplicated at the other end and the superimposed voltages oppose one another so that, normally, no current flows at the superimposed frequency. On fault such current flows and operates the tuned relays G through the transformers J. A centrifugal switch on the frequency-changer admits the superimposed frequency only when the prescribed frequency is attained.

Title: Detector for radio navigation receivers
IPC: G01S1/24
Filed: 1956-09-26
Abstract: 813,200. Radio navigation. SPERRY RAND CORPORATION. Sept. 26, 1956 [Nov. 7, 1955], No. 29380/56. Drawings to Specification. Class 40 (7). Relates to a Loran receiver of the type disclosed in Specification 771,778 in which the time interval between two trains of pulses of equal repitition rate transmitted respectively from spaced A and B stations is measured by matching the A and B pulses displayed on a C.R.T., the relative amplitudes of the displayed pulses being automatically balanced and the absolute amplitudes of the displayed pulses being automatically controlled by an A.G.C. voltage derived from the weaker of the A and B pulses. If a conventional diode detector is used in such a system than when a noisy pulse is received the base portion of the detected pulse is obscured by the rectified noise, Fig. 4c (not shown), and if the signal/noise ratios of the received A and B pulses are unequal then accurate matching of the detected A and B pulses is difficult and this may result in a timing error. According to the present invention, such timing errors are reduced, Fig. 5 (not shown), by manually adjusting the bias on the detector, Fig. 1 (not shown), so that it passes only signals of amplitude greater than the average noise level. U.S.A. Specification 2,651,033 also is referred to.

Abstract: 680,294. Casting arched structures in situ. WALLER, J. H. DE W. Nov. 15,1950 [Nov. 17, 1949], No. 29462/49. Classes 20(ii) and 20(iv) An arched structure, the curve spanwise of which, as shown in Fig. 1, is inverted catenary and the cross section at right angles to the span as partly shown in Fig. 4 is a catenarian wave form, is cast in situ by applying concrete to permanent flexible shuttering 10 supported on arch reinforcement which is supported on a temporary gantry A from which it is severed when the concrete is set. In one method the gantry which is mounted on wheels at 3 comprises three arched girders A joined by transverse girders 2, each girder being at the crest of a wave of the arch cross-section. Reinforcement rods 5 for the trough of the waves are bent to catenarian form and suspended from hooks 9 on the gantries by means of intermediate tubes 8 and joined by reinforcing rods 6 for the wave crest. Reinforcing rods 7 are laid over and at right angles to these rods and follow the curve of the arch. When the concrete, which may be applied by a gun has set, the ends 5b of the trough rods 5 are severed and the gantry is moved on tracks 4b to cast the next section. The sections may be continuous or connected by expansion joints or arched roof lighting. The shuttering may be expanded metal, hessian or scrim. The arched structure may have end walls with doors or the springing on one side of the arch may be supported on a lintel supported by buttresses providing a wide entry along the side of the structure. The lintel may be of arch form and in one construction a number of arched lintels are supported on common buttresses and the outer ends of the end lintels are supported on longitudinally arranged buttresses. Each girder of the gantry A is formed of a number of segments joined end to end and the gantry is erected by assembling the first two segments of the three girders at the foot of the gantry with the corresponding transverse girders 2, raising the outer end by jacks or cranes and adding further segments and raising until the arch is complete. A travelling cradle shaped to the trough form is slung between the girders for the workmen and moved up as the work proceeds. Specification 545,334 is referred to.

Patent GB-1049747-A (GB)
Title: Production of polycarbonates
IPC: C08G64/20
Filed: 1963-07-26
Abstract: Polycarbonates are made continuously by passing an organic dihydroxy compound and a carbonate ester into a reaction zone at 200 DEG  to 325 DEG  C., maintained first at a pressure sufficient to suppress volatilization of the carbonate ester, then subjecting the resulting mixture of molten polycarbonate resin and volatile by-products to reduced pressure to volatilize the by-products, continuously removing volatilized by-products from the zone, and continuously extruding the resulting molten polycarbonate from the zone. The carbonate ester is preferably a dicarbonate of formula <FORM:1049747/C3/1> or a biscarbonate of formula <FORM:1049747/C3/2> where R is the residue of an aliphatic, cycloaliphatic or aromatic monohydroxy compound and Z is the residue of an aliphatic, cycloaliphatic or aromatic dihydroxy compound. In a modification, the mixture of dihydroxy compound and carbonate ester is replaced by a biscarbonate or a low molecular weight polycarbonate. The process is preferably effected in a twin-screw extruder in which each worm flight is interrupted by two pressure blocks to form three zones in the first of which the pressure is such as to prevent volatilization of the by-products, in the second of which the pressure is reduced so that up to 95% of the volatile products are removed and in the third of which pressure is still further reduced to remove the remaining volatile products. Molten polycarbonate is extruded from the third zone as spaghetti-like rods which are cooled and then chopped. Catalysts for the reaction are hydrides of metals of Group I, II and III; oxides, hydroxides, phenates and alkoxides of metals of Group I and II; and metal alkyls of metals of Groups I, II, III and IVa.  Examples describe the preparation of polycarbonates by reacting (1) Bisphenol A and its bisphenyl carbonate; (2) 2,2 - C4,41 - dihydroxydiphenyl) - butane, hydroquinone and diphenyl carbonate; (3) 1,1-(4,41 - dihydroxydiphenyl) - cyclohexane, 1,6-hexanediol and the bisphenyl carbonate of bisphenol A.  Reference has been directed by the Comptroller to Specifications 772,627 and 808,489.
