Abstract: 516,102. Centrifugal fans. GRENE, G. H. S., and WILD-BARFIELD ELECTRIC FURNACES, Ltd., Nov. 15, 1938, No. 33225. [Class 110 (i)] [Also in Group XII] In a furnace of other treatment chamber for materials in which air or gas is circulated by a fan the direction of circulation can be reversed by shifting the fan or parts co-operating therewith. In the furnace shown the fan 12 has upper and lower axial inlets, and when in its lowered position with the upper inlet effective, the direction of circulation is upwards around the casing 7 and downwards through it. When 'the fan is raised the upper inlet is closed by the baffle 24, the lower inlet becomes effective, and the direction of circulation is reversed. In a modification, Figs. 3 and 4 (not shown). the fan is stationary axially, and vertically movable baffle elements are arranged to close either the upper or lower inlet to the fan and to direct the output through or around the casing 7. Specification 507,545, [Group XII], is referred to.

Title: Improvements in or relating to a circuit for regulating alternating voltage or current
IPC: G05F1/12
Filed: 1946-11-08
Abstract: 626,673. Automatic control systems. PHILIPS LAMPS, Ltd. Nov. 8, 1946, No. 33292. Convention date, May 22, 1943. [Class 38 (iv)] The difference between an A.C. voltage across a load and a comparison voltage, of the same frequency, is applied to an amplifier, the output of which feeds a transformer in series with the supply. As shown, the load 1 is supplied from the source 2, 3 subject to the influence of the transformer 6 energized from the amplifier 4. The amplifier input voltage consists of the difference between that across the load 1 and that of the comparison source 5. The latter has the waveform required by the load and is adjustable either to a fixed value or in accordance with a predetermined law. A fraction of the load voltage only may be employed for the comparison, as indicated by the dotted lines. It is stated that the device may be used in conjunction with a variable tapping transformer, the latter serving to remove the large slow changes in the load voltage and the former the rapid small changes. In a second embodiment, not shown, the load current is controlled by employing the voltage developed across a resistor in series with the load, in place of the P.D. across the load itself.

Filed: 1920-11-25
Abstract: 176,085. Borton, A. F. Nov. 25, 1920. Rod couplings.-Relates to devices for connecting tubes together of the kind in which a screw provided with one or more nuts is adapted to expand a ring or the like within the tubes. According to the invention, one or more expansible plain rings having a single split, together with non-expansible members and nuts are fitted on the screw in such a manner that the rings are expanded by pressure from both sides. In the device shown in Fig. 1, for connecting two tubes a, b in alignment, a double-ended screw 2 passes through a centre block 1, and carries a series of wooden split rings 5, Fig. 4, which have rounded side faces. On either side of each ring 5 are a pair of collars 4 or a collar 4 and nut 7. When the parts are assembled as shown, and the tubes a, b are turned in opposite directions, the nuts 7 move slightly inwards towards the block 1, and the split rings are expanded against the walls of the tubes.

Abstract: 1486761 Moulding housings on to strips AMP Inc 12 Aug 1976 [5 Sept 1975 28 June 1976] 33532/76 Heading B5A [Also in Division H2] Housing members 14, 16 of filled plastics material for two part electric couplings, are made by moulding the members on to a polyimide strip 74 having two series of apertures 48, 76 therein. The apertures 76 have short radial slits (not shown) which allow expansion of the apertures as the plastics material flows therethrough. As the material cures the studs so formed are gripped by the contracted edges of the apertures to give an integral assembly. Pairs of housing members 14, 16 are severed from adjacent pairs and the polyimide strip acts as a hinge so that the members can be folded and locked together to form a housing (see Division H2). The apertures 48 provide access for connectors to pass into the housing.

Title: Improvements in wireless aerials and feeders
IPC: H03H7/48
Filed: 1953-12-04
Abstract: 744,116. Aerials. PETTIT, F. R. Oct. 13, 1954 [Dec. 4, 1953], No. 33830/53. Class 40 (7). A wide-band aerial comprises a single loop of screened, e.g. coaxial, cable, the end of the inner conductor being coupled to the outer conductor to complete the loop as shown in Fig. 2. The loop may be circular or rectangular and should enclose as large an area as possible. To avoid the aerial having a directive effect the upright sides may be arranged on adjoining walls of a room and the horizontal sides carried round the corner between them (Fig. 3, not shown). The aerial may be coupled to as separate feeder or the inner and outer conductor of the loop may be integral with the inner and outer conductors of the feeder as shown in Fig. 2. Owing to its low output impedance the aerial may be arranged to feed more than one receiver, the live terminal of each receiver being connected to the inner conductor of the feeder through a resistor of from 150 to 300 ohms. The response and output of the aerial system is dependant on the length of the aerial loop and of the feeder. A formula is given relating these to a frequency of parallel-tuned resonance in the medium waveband and at which the receiver input voltage is higher than under non-resonant conditions. Shunt capacity, which can be inserted or removed by a switch, may be provided at the receiver end of the feeder to transfer the resonance point to the long waveband when required. Where the feeder and loop lengths are long it is preferred to cancel the resonances and render the aerial resistive. This may be done by using a matching transformer T and series capacitor C<SP>1</SP> at the junction between the aerial loop and the feeder as shown in Fig. 6. The transformer T may be a 3: 2 step-down transformer and a 1: 3 or 1: 5 step-up transformer may be provided at the receiver input. In a modification a series capacitor and inductor are connected across the aerial loop at its junction with the feeder and the feeder is coupled across the inductor only (Fig. 5, not shown).

Abstract: A ceramic dielectric for capacitors is prepared by making powdered barium titanate of high purity into a form, firing the form in a reducing atmosphere at a temperature between 1330 DEG C. and p  1550 DEG C. until all the barium titanate is transformed to its hexagonal polymorph, cooling the form over a temperature range of 1330 DEG C. to 1000 DEG C. for an hour or less and then firing the form in an oxidising atmosphere for one to five hours at 1000 DEG C. to 650 DEG C.  This forms a barrier layer dielectric since during the oxidation process the granules of barium titanate (diameter of of about 1 micron) become surrounded by a very thin (about 100  ) barrier layer, the material as such being substantially electrically conductive but in the form of grains mutually isolated by thin insulating films.ALSO:A method of manufacturing an inter granular barrier layer ceramic dielectric for capacitors includes the steps of making powdered barium titanate of high purity into a form, firing the form in a reducing atmosphere at a temperature between 1330 DEG C. and 1550 DEG C. until all the barium titanate is transformed to its hexagonal polymorph cooling the form over a temperature range of approximately 1330 DEG C. to 1000 DEG C. for approximately an hour or less and then firing the form in an oxidising atmosphere for one to five hours at a temperature between 1000 DEG C. and 650 DEG C.
