Title: Improvements in or relating to mirror arrangements for use in the transmission or reception of electrical waves
IPC: H01Q19/19
Filed: 1933-06-27
Abstract: 410,336. Directive wireless signalling. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. June 27, 1933, No. 18334. Convention date, July 8, 1932. [Class 40 (v).] A mirror system for producing a beam of short waves comprises a main mirror, an auxiliary mirror, reflecting back energy on to the main mirror, and a second auxiliary mirror replacing that part of the main mirror which is screened by the first auxiliary mirror. In one embodiment, Fig. 1, the main paraboloidal mirror PQ has a focal point F which is also the centre of the first auxiliary spherical mirror BCD. Radiation produced at the point F cannot proceed into the beam without reflection at one of these mirrors. Radiation in the angle GFE cannot leave the main mirror owing to the mirror BCD. It is therefore reflected back on to the source by a second auxiliary spherical mirror GAE centred at F. In a second embodiment, Fig. 2, the first auxiliary mirror BCD is ellipsoidal with foci F1, F2, the focus F1 coinciding with the focus of the main paraboloidal mirror PQ. The second auxiliary mirror GAE is part of the same ellipsoid. For reception, a reradiating receiver is placed at F1 and a second receiver at F2 while for transmission, a transmitter is disposed at each of the foci, that at F2 controlling that at F1 by back coupling. In a further embodiment, (Fig. 3, not shown), the two auxiliary mirrors are paraboloidal. In each embodiment, the mirrors may be figures of rotation or cylindrical figures of translation. The magnitudes of the relative distances of the foci and the focal distances of the mirrors are discussed in the Specification. The Specification as open to inspection under Sect. 91 comprises also an arrangement with only one auxiliary paraboloidal mirror. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,106,692. Stranding cables. ETUDES ET FABRICATIONS. 3 May, 1965 [4 May, 1964], No. 18580/65. Heading H1A. [Also in Division H2] A quad winding machine relates pulling speed to rotational speed of the reel assembly supplying the cores in such a way as to produce continuous variation of the pitch of the quad. A tachometer provides a voltage representative of reel speed and this voltage is fed to a cam and potentiometer arrangement of the type shown in Fig. 3. The rate voltage is applied across the first potentiometer 31, the slider of which is driven from a cam follower 47. This cam is geared by two wheels which have tooth numbers which are not divisible by one another to another cam 60 driving a second potentiometer slider 35 and a similar arrangement drives a third slider 45. The output of the system is used to control the pulling speed, the gear ratio and the cam profiles, which are such that the slopes at points of equal radius are different, ensuring a continuous variation of the pitch of the quad. The direction of quadding may be controlled by a change-over switch and the pitch may be further adjusted by manual control. Two potentiometers only may be used.

Title: Improvements in or relating to the manufacture of textile fabrics of glass fibers
Inventor: WAGGONER JACK HOLMES
IPC: C03C25/475
Filed: 1951-08-10
Abstract: Glass-fibre fabrics are given a soft and supple hand and a resistance to creasing, and the individual fibres are crimped or curled, by heat-setting at 400 DEG -1300 DEG F. for a time ranging from 70 hours at the lower temperature to a few seconds at the higher temperature to relax the fibres and set the weave, then applying a fibre-coating material and finally heat-curing to fix the coating on the surface. The heat-setting may be effected in an oxidizing atmosphere.  Relief or intaglio-designs may be pressed on the fabric during the heat-setting operation.  Fabrics treated according to the process may be subsequently torn apart to separate the curly fibres, which may then be carded and spun.  The coating agent may be applied in aqueous or organic-solvent solution or emulsion by spraying, flow- or roller-coating, brushing, dip-squeeze or padding operations, and in certain cases may be applied by vapour deposition.  Suitable types of coating agents are the following: thermosetting resins, e.g. phenol-aldehyde, amine- or amide-aldehyde, and polyhydric alcohol-polybasic acid condensation products, and organo-silicon compounds; thermoplastic resins, e.g. polyvinyl, polyacrylate and polyalkyl-acrylate resins, polyethylene and polybutylene resins, and butadiene-acrylonitrile and butadiene-styrene copolymers; cellulose esters and ethers; rubber, chloroprene, rubber hydrochloride and chlorinated rubber; natural resins, e.g. shellac and dammar; proteins, e.g. gelatine, casein and zein; oils, waxes, cationic-active amine compounds and Werner-complex compounds; many examples of the above compounds are given.  Dyes and pigments may be incorporated in the coating compositions, or alternatively the treated fabric may be subsequently coloured. Glass-fibre fabrics containing, in addition, asbestos fibres may also be treated. Specification 586,793, [Group VIII], is referred to.
