Abstract: 446,068. Heating by circulation of fluids ; heating water. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Lidingo, near Stockholm. Sept. 16, 1935, No. 25689. Convention date, Nov. 15, 1934. [Classes 64 (i) and 64 (ii)] In a system for heating water by steam circulation, a domestic boiler 1 is provided with cold water supply pipe 3 and hot water draw off pipe 2, and is heated by a coil 5 in which steam is condensed. The coil 5 is connected to a coil 10 surrounding the combustion space 11 of a continuously burning stove having a heat-accumulating part 13 which also acts as a hopper for the fuel. The stove is surrounded by heat-insulation 19, 20. The condensate return pipe 21 is connected to a vessel 24 and thence to an expansion vessel 22. Warm condensate forced into the vessel 24 remains at the top, and is consequently warm when returned to the system by reverse flow. Transfer of heat between the circulation system and the vessel 24 may further be prevented by heat-insulating the inlet' and outlet pipes 25, 26 which extend into the vessel 24, by the provision of double walls. An air-escape pipe 9 is provided.

Patent GB-259521-A (GB)
IPC: H03B11/06
Abstract: 259,521. Du Prel, G. F. Aug. 11, 1925. Spark-gap oscillation generators. - In a highfrequency spark - discharge generator, suitable for radiotherapeutic purposes, the low-frequency supply circuit 1, for example electric lighting mains, is bridged by a tuned circuit comprising a split inductance 2, 2 and a condenser 3, the latter being shunted in turn by a sparkgap 4 and the primary coil 5 of a Tesla transformer. The inductances 2, condenser 3, and the capacity of the gap 4 are tuned as a whole to the frequency of the alternator 1, thus affording a steady and adjustable energy supply to the primary circuit so long as the spark-gap is in operation. If the spark-gap is switched off, the circuit 1, 2, 3, 2 is detuned and takes but little energy from the mains. In the case of a, direct-current supply, Fig. 2, the condenser 3 is charged through a coil 7 which operates the make-and-break switch 8, 9, the contacts of which also serve as a sparkgap. The points 8, 9 are preferably of cooled tungsten. When used with an alternating supply the coil 7 may be short-circuited at 10, and the contacts 8, 9 used as the spark-gap; or the coil and interrupter may be removed bodily and replaced by a plug-in gap of known type such as 4, Fig. 1.

Abstract: 297,035. British Thomson-Houston Co., Ltd., (Assignees of Harrison, F. W.). Sept. 12, 1927, [Convention date]. Drawings to Specification. Condensers. - A method of treating paper or other cellulose material with a mineral oil of the paraffin series for electrically insulating purposes consists in keeping the material either by itself or when assembled with the apparatus such as condensers, transformers, cables, etc. to be insulated, immersed, with or without pressure, in the oil heated to a temperature of 150-200‹ C. until the trapped air and gases produced by the action of the oil on the cellulose material cease to be evolved. According to one application dry cellulose pulp is felted by mechanical means or by electrical precipitation and treated in hot oil which may be under pressure. In another application cotton or other organic fabric is pressed into a mat under oil, and heated under pressure, In preparing electric cables, paper strips are wound over the conductor core, and the assembly heated in an oil bath. The lead sheathing may be then applied. The Specification as open to inspection under Sect. 91 (3) (a) states that instead of oil, vaseline, nitro-benzene, the higher alcohols, beeswax or varnishes may be used for the bath. This subjectmatter does not appear in the Specification as accepted.

Abstract: 394,961. Traffic signals. MAUGHAN, W., Ing Head House, Holmfirth, near Huddersfield. Sept. 18, 1931, No. 26121. [Class 118 (ii).] Apparatus automatically operated by the passage of vehicles along a road is constructed so as to record, in addition to the total number of vehicles passing, the " momentum and weight effect category of the vehicle, and the aggregate number of vehicles in each such category. Each vehicle depresses a road area composed of blocks a attached to a rubber or spring steel sheet b having blocks b<1> which extend into recesses in a yielding base c and by engaging wires d, e operate recording mechanism connected thereto. Pulleys b<2>, c<1> are provided for the wires d, e. Fig. 2 shows a form of blocks f, which may pave a portion of the roadway and which on being depressed by a vehicle compress air in cavities f<1> for delivery by a pipe f<2> to the recording mechanism, valves f<6> being provided to admit air to the cavities. The blocks f may be reinforced by springs. In another modification, spreading of the arched road treadle plates operates the recording mechanism. Light traffic may expel air from an upper chamber k, Fig. 8, to operate one recording mechanism, whilst heavy traffic may expel air from a lower series of yielding air pockets k<1> to operate another recording mechanism. Alternatively, the light traffic may close an electric circuit by depression of the yielding support j. A swinging signal t may be struck by a hammer from the transmission. mechanism when a vehicle passes. Each half of the roadway may have its own equipment of transmission apparatus.

[Also in Divisions H1 and G3] An amplifier circuit utilizes a field-effect transistor consisting of a semi-conductor of first conductivity type having a channel layer of opposite conductivity type and a first gate electrode (G1) insulated from the channel layer and a second gate electrode (G2) connected to the semi-conductor. In operation, variation of voltage between gate (G2) and source (S) has a pronounced effect on the drain current v gate (G1) voltage characteristic as depicted in the curves of Figs. 9-14 (not shown). The appropriate characteristics may be selected by biasing gate (G2) relative to (G1) by means of a cell or a constant-voltage diode or charged capacitor. In Fig. 7 (not shown) the incoming signal is rectified (at r) and smoothed (at C) so as to provide the requisite bias. In Fig. 4 (not shown) the incoming signal is applied to the gate (G2) whilst the insulated gate G1 is biased by means of a cell. In Fig. 17 (not shown) a three-stage directly coupled amplifier has each gate (G2) provided with a separately adjustable bias. Transistor construction and automatic current control circuits are described (see Divisions H1 and G3].

Abstract: 507,461. Directive wireless systems TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE: Sept. 7, 1938, No. 26182. Convention date, Sept. 8, 1937. [Class 40 (v)] In a direction-finding system in which " night effect is eliminated by an arrangement of a plurality of frame aerials in parallel planes disposed on the circumference of a circle, pairs of frames being connected in opposition and to the field coils of a goniometer, two such arrangements are combined, the planes of the frames of the two arrangements being set at an angle to each other. This provides a greater sensitivity and also, when operating with vertically polarized waves only, gives two zero positions instead of the four obtained wth the single arrangement. In the Figure, the two systems comprise frames 1, 1 and 11, 1<1> respectively connected in opposition and to the field coils of the goniometer a, and the frames 2, 2 and 2<1>, 21 similarly connected to goniometer b and at right-angles to the planes of frames 1. The search coils of the two goniometers are in parallel planes and may be rotated together on the same shaft; they may be connected to the receiver either directly or in alternation when applied to a "flicker" type of receiver. A sense determining voltage may be applied to the goniometers from crossed frames located at the middle of the direction-finding system. The Specification as open to inspection under Sect. 91 refers to a modification in which any two frames connected in opposition are not in the same plane but in parallel planes and also to a modification in which each arrangement of frames in parallel planes comprises three frames spaced at 120‹ round the circumference of a circle.
