Patent GB-1213077-A (GB)
Title: Fabric forming apparatus
Inventor: BECKER MARVIN
IPC: B29C51/08
Filed: 1969-07-03
Abstract: 1,213,077. Sheet forming. M. BECKER and H. BELMUTH. 3 July, 1969, No. 33561/69. Heading B5A. Hollow articles, such as brassiere cups, are deep drawn from a thermoplastic fabric of, for example a polyester, by clamping the fabric, deep drawing it in one direction using a heated male member, and then deep drawing it in the other direction using a cool male member upon which the article is allowed to set. In the embodiment illustrated in the figure, the sheet F is slidably clamped between a table 14 and a holding plate 44 resiliently mounted by springs from an upper plate 42 and is drawn downwardly by an air cylinder actuated heated male die 16. The die is then withdrawn and simultaneously a similarly actuated lower unheated male die 18 is raised so that the sheet is transferred from the upper to the lower die and the direction of draw reversed.

Title: Method of and apparatus for receiving high-frequency electric signals
IPC: H04B1/12
Filed: 1920-11-27
Abstract: 155,244. McCaa, D. G. Dec. 4, 1919, [Convention date]. Wireless telegraphy and signalling. -Atmospheric strays are eliminated by splitting-up the received energy into two equal components traversing different paths in a suitable receiving-structure in such. a way that their combined effects upon the telephones are equal and opposite, and at the same time impressing upon the signal energy in the same receiving-structure locally-produced oscillations to create beat effects which follow the same paths, but are displaced 180 degrees, so that they act upon the telephone with cumulative effect. The aerial circuit A, P, C is coupled to an intermediate tuned circuit P1, P2, C1, the inductances P1, P2 being so connected that the magnetic. flux linking with the secondaries S1, S2 is in the same direction. The tuned circuits comprising the inductances S1, S, are connected respectively across the two grids g, g1 and to common filament of the thermionic valve V. As the potentials thereby impressed upon these grids are of the same sign and magnitude, the corresponding plate currents flowing through the inductances P3, P4 will be equal but in opposite directions, and will balance out, so that no resultant note will be received ;n the telephones T. Under these circumstances atmospheric disturbances are eliminated. In order to detect signal energy, the incoming waves are heterodyned with local oscillations produced by a thermionic oscillator V2, the grid and plate circuits of which are coupled together through inductances L3, L4. These local oscillations are transferred through a coupling P7, S4 to a tuned intermediate circuit containing inductances P5, P6, which impress corresponding magnetic fluxes upon the coils S1, S2 to create beat effects with the signal waves. As the magnetic flux through the coil P5 is in the opposite direction to that passing through the coil P6, the resultant beat maximum in the coil S1 will correspond to a beat minimum in the coil S2, and these effects on being applied to the grids g, g1 will give rise to plate currents through the primaries P3, P4 which are 180 degrees out of phase and which therefore react upon the secondary S3 with cumulative effect, and are so received in the telephones T after passage through the amplifier V1. Beat effects resulting from the interaction of weak or strong atmospherics and the locally generated oscillations are minimized by regulating the. relati-vo, strength of the oscillations produced by the valve V2. In a modified arrangement, the incoming signals are heterodyned before being applied to the secondaries S1, S2, the resultant primary beats being combined with oscillations from the valve V2 to produce secondary beats, which are then applied to the valve V as before. The coils P1, P2 may be inserted directly in the aerial circuit instead of as shown in Fig. 1, and similarly the coils P5, P6 may be combined directly with the valve V2. Instead of the double-gridded valve V, two valves of ordinary construction may be used in parallel.

Filed: 1928-06-01
Abstract: 322,500. Pollak, J. E., (Ganz-Fele Villamossagi Reszvenytarsasag). June 1, 1928. Divided on 322,199, [Class 38 (ii), Electric currents, Converting &c.]. Boosting by static transformers.-The voltage of alternating-current systems is regulated by means of at least two transformers I, II, or a transformer with a single iron body having at least two closed flux paths, each transformer or path having a series coil f<1>, f<2> and a control coil g<1>, g<2> directly short-circuited for the purpose of regulation, and a shunt-coil s<1>, s<2> being arranged so that its flux passes through the coils f<1>, f<2> in opposite directions. The voltage of the lines L is increased or decreased by short-circuiting the coil g<1> or the coil g<2> gradually by resistances or instantaneously by switches. A voltage drop due to the load in the coils f<1>, f<2> when neither of the coils g<1>, g<2> is short-circuited is avoided by then interconnecting the coils g<1>, g<2> in a circuit A so that the flux of the coil, s<1>, s<2> produces equal and opposite voltages in the coils g<1>, g<2> and no current in the circuit A and that currents tending to equalize, the flux in the paths I, II flow in the circuit A when the fluxes are unequal. This interconnection is interrupted simultaneously with the short-circuiting of either coil, the switches or variable resistances such as k<1>, k<2> being mechanically connected. The resistances k', k<2> may be water resistances. More than two series transformers with coils successively short-circuited may be used. Specification 258,885, [Class 38 (ii), Electric currents, Converting &c.], is referred to.

Divided out of 447,754, [Group XXXVI]. [Class 39 (i)] [See also Groups I and IX] An insulated grid, such as a photoelectric mosaic screen of a cathode-ray tube is formed of crossed wires which are coated with electrically insulating vitreous material and are held together by fused joints between the insulating coatings at points where the wires cross. Two sets of wires 28, coated with glass in the manner described in Specification 447,754, are held by means of wax in grooves in copper plates 26, which are faced with nickel. The plates are heated and pressed, preferably until they are in contact, between thick metal plates so that the glass is welded at the intersections. The initial radius of the glass-covered wires is less than that of the grooves. After cooling the plates are stripped off or dissolved in acid. The grooved plates may be obtained from a wax master and are provided with location holes ; the grooves may not extend to the edges of the plates. Each plate may be provided with additional grooves 33 which are adapted to house the wires in the other plate on pressing. In a modification, a set of wires are laid in grooves in a plate, another set is laid on top of the first set and a grooved plate is then laid on top and the whole heated and pressed. The grid may be stripped of its insulation at the ends and mounted by welding within a square aperture in a metal plate. The holes in the grid are filled with metal rivets coated on one side with photo-electric material. Specification 446,661 also is referred to. The Provisional Specification states also that a small amount of weaving of the wires may be utilized to hold the wires together during construction.
