Title: Improvements in or relating to electrical energy transferring, transforming, coupling and the like devices
IPC: H03H7/48
Filed: 1926-10-02
Abstract: 282,905. Franklin, C. S., and Green, E. Oct. 2, 1926. Coupling oscillating and radiating circuits; receiving systems. - Relates to electric energy transferring, transforming, coupling, and like devices, particularly in connection with feeding multiple aerial systems for wireless signalling. A feeder cable carrying high-frequency currents is connected to a working circuit such as an aerial through a coupling device comprising shunt and series resistances designed to make the effective load on the feeder equal to its surge impedance. As shown in Fig. 1, an inductive reactance L is inserted in series and a capacitive reactance C on shunt with the line, but these impedances may be reversed in position. When output resistance is required to be stepped up, the input is applied across the terminals X, YL. If it is to be stepped down the input is applied across the points A, B. If the load on the secondary is a resistance R and a primary load of 2R is required, then the inductance L should have a reactance R ohms and the condenser C and reactance of 2R ohms at the working frequency. In Fig. 3 main feeder section M is supplied with high-frequency current at the points A, B which is attributed to two sub-feeders S1, S2 arranged in parallel at the output side. Each of the sub-feeders may again supply two further feeders similarly arranged in parallel. The coupling device may comprise a substantially uniform length of feeder an appreciable fraction of a wavelength long, inserted in series between a feeder and its load. In this case if R1 is the load resistance and R2 the required effective impedance, a quarter wavelength of feeder designed to have a surge impedance R1, R2 is inserted as the coupling device. Or the inserted length of cable may be replaced by an artificial line built up of impedance elements. The method is also applicable to the reception of wireless signals.

Patent GB-425048-A (GB)
Title: Improvements in the manufacture of portland cement
IPC: C04B7/00
Filed: 1933-09-05
Abstract: In the manufacture of Portland cement, the calcareous material is less finely ground than is usual for normal Portland cement, the clay is either coarsely or finely ground, and the materials are burned in the kiln in such a manner that some of the lime remains uncombined, this free lime in the clinker being then changed to calcium hydrate without substantially hydrating the cement, e.g. by treatment with steam at 170-400 DEG  F., during or after the grinding.  The coarsely crushed and pulverized calcareous material can be mixed with the clay before it enters the kiln, and the mixture may be dry, semi-dry or in a slurry state.  The mixture is not finely ground together, but if desired the calcareous material may be coarsely pulverized together with the clay.  In no case will the residue of raw mix on a No. 170 sieve by less than 20 per cent, and in general it will be between 20 and 45 per cent.  Instead of mixing the materials before entering the kiln, the clay may be fed in separately, e.g. by being blown into the kiln by preheated air.  The resulting cement may be divided by passing it through a suitable separator into two parts, one part containing a larger share of the calcium hydrate than the original product, and the other part containing a smaller share. Specification 389,872 is referred to.

The cores are respectively linked with one of three phase windings U, V, W, carrying the A.C. i<SP>1</SP>, i<SP>2</SP>, i<SP>3</SP> to the rectifiers, and with one of three series connected windings A<SP>1</SP>, A<SP>2</SP>, A<SP>3</SP>, connected to the operating coil of a device which upon flow of current through these coils protects the rectifiers by short-circuiting the A.C. supply leads and bringing out the main C.B. or by applying blocking volts to the rectifier grids. In Fig. 5 which shows curves of the current in the three supply phases, currents i<SP>1</SP>R and i<SP>2</SP>R flow in rectifiers K', K2 and windings R<SP>1</SP>, R<SP>2</SP> upon back firing of K<SP>1</SP> at the end of period ST, of shall current produced by a switching choke. While cores R<SP>1</SP>, R<SP>3</SP> remain saturated by current J g  (asisted in the first case by fault current i<SP>1</SP>R, fault current i<SP>2</SP>R reverses the flux in core R2 and produces a tripping current in the coil of the protective device. The cores may be wound strip and may ea@ carry a premagnetization D.C. winding. They may be concentrically arranged with the phase widings appropriately bent, Fig. 2 (not shown), or eccentrically arranged with these windings as straight bars, Figs. 7, 8 (not shown). In applying the invention to a three phase bridge circuit, placing of the cores at C, Fig. 9, may result in delay in tripping if the backfire occurs at the end of a negative current transmission period. To avoid this, sets of three cores may be placed at E, F respectively, or six cores in pairs carrying oppositely wound A.C. coils may be placed at C. As an alternative, three cores with A.C. coils with junctions O, P, Q, at their centre taps, Fig. 12 (not shown), may be used. In modifications there may be selective phase protection, several turns per A.C. coil or a common coil instead of the separate coils A<SP>1</SP>, A<SP>2</SP>, A<SP>3</SP>.

Title: Improvements in or relating to methods of fusing together two plastic components
IPC: B29C65/00
Filed: 1960-07-20
Abstract: 910,425. Seaming non-metallic sheet material. PLUMMER, W. A. July 20, 1960, No. 25373/60. Class 42 (1). [Also in Group XXV] A method of fusing together two plastic components having differing shore hardness characteristics comprises cooling the component of lower shore hardness and then heat-sealing the two components together while the component of lower shore hardness is in the cooled condition. As shown, the invention is applied to secure a pair of plastic slide fastener tapes 13 and 14 to a strip 32 of a plastic, to fabricate plastic tubing. The slide fastener tapes are first passed through an oven 11 under tension and then between slitter rollers 19 and 20 to relieve stresses and enable the tapes to lie flat. The separated webs 15 and 16 of tapes 13, 14 are then fed to the tubing assembly together with a sheet 32 which has previously passed through a pre-chilling chamber 23 and the tapes are united to the sheet by welding electrodes 27, 28. The assembled tubing tape is advanced intermittently by feed rollers 37 and is wound up on spool 40. The pre-chilling of sheet 32 is said to render its shore hardness substantially equivalent to that of the tape material such that during welding there is no differential expansion and the combined tapes and sheet do not wrinkle. The assembled tubing tape may be used to wrap around electric cables the two parts of the fastener being locked together by a slide fastener in the usual way or it may be used to enclose insulation around steam pipes.
