Title: A method of, and machine for, printing on metal
IPC: B41F17/00
Filed: 1932-05-04
Abstract: 400,684. Making metal tape. TAPLIN, H. J., 207, Wembley Hill Road, Wembley, Middlesex. May 4, 1932, No. 12880. [Classes 83 (ii) and 83 (iv).] Beading.-A sheet-metal band 40 is passed between bending-rollers 26, 27 having projecting and bevelled edges respectively, whereby the edges of the band are curled so that the material is adapted for use in machines for binding packing cases. Winding.-The band is then printed and is wound on a drum 15. Rollers 30, 31 shaped like the rollers 26, 27 may feed the band through the machine, the drum 15 being rotated through a friction clutch which slips as the diameter of the roll increases, or the drum may be the sole feeding-member. An indicator 18 shows the number of turns on the drum 15, and a slidable support 17 allows removal of the drum.

Filed: 1942-09-15
Abstract: 559,569. Photographic printing apparatus. HARVEY, E. A. Sept. 15, 1942, No. 13000. [Class 98 (ii)] Control of the printing light to compensate for local variations of the overall density of the image to be copied is obtained by interposing between the light source and the image a masking member comprising a number of separatelyadjustable apertures disposed so as to cover the whole field of the image. The member may be used in a contact printing cabinet, and comprises in one form a plate 1 provided with rows of apertures 4 with each of which is associated a slidable shutter plate 19 (one only of which is shown) connected by a narrow bar or strip 18 to an external adjusting plate 17. The knobs 22 of the various plates 17 are arranged in keyboard pattern and may project into a cover plate slotted to limit the movement of each knob. Beneath the end occupied by the apertures, the plate 1 has slideways for receiving a safelight. The printing apparatus preferably includes an opal diffusing sheet between the-plate 1 and the image to be copied. The various shutters may be adjusted while observing, with the safelight temporarily in position, the image formed on a sensitive sheet in printing position, viewed by transmitted light when printing is performed by contact. Instead of a single apertured plate 1, a bank of identical plates may be superimposed, one row of apertures in each plate being associated with one row of shutter plates. The shutters may be logarithmically curved at one end as shown ; they may be themselves apertured ; and they, as well as the plate 1 may be made of metal or other stiff material, e.g. cellulosic sheet rendered opaque by photographically producing silver or dyestuff deposits thereon.

Title: Improvements in or relating to voltage-dependent capacitors
IPC: H01L29/93
Filed: 1956-04-27
Abstract: 838,512. Semi-conductor devices. SIEMENS & HALSKE A.G. April 27, 1956 [April 28, 1955; April 29, 1955; April 5, 1956], No. 13036/56. Class 37. [Also in Group XL (c)] A voltage dependent capacitor comprises a PN junction on one side of which the uncompensated activator concentration changes with increasing distance from the junction from a relative maximum to a minimum and back again to a value higher than said relative maximum. In order to obtain a capacitor of low resistance the P and N zones should be less than 100Á thick and may suitably be prepared by deposition from the liquid or vapour phase, by spraying or by cathode evaporation. Suitable amounts of impurity are incorporated in the zones either during or after the deposition. The loss angle may also be reduced by use of monocrystalline materials with high carrier mobility such as elements of the fourth group and alloys or compounds thereof, or A III B V , A II B VI  and A I B VII  compounds and mixed crystals thereof. The semi-conductor surface is preferably treated to remove surface imperfections either by treatment with ultra-violet radiation or by providing a surface dielectric layer, e.g. of perovskites such as titanates. A PN diode capacitor with a doping concentration distribution along its length, as shown in Fig. 1, may be produced by simultaneously or sequentially alloying and diffusing a donor with a high diffusion velocity and low distribution coefficient and an acceptor with a low diffusion velocity and high distribution coefficient into one end of a uniformlydoped N-type body. A pair of donor materials of high diffusion velocity and low distribution coefficient, and low diffusion velocity and high distribution coefficient respectively, are alloyed and diffused into the opposite end of the body either simultaneously or sequentially. In another method donor material is diffused into one side of a weakly N-type crystal prior to the alloying thereto of an acceptor containing wire. Following the diffusion of donor material into the opposite side of the crystal a still heavier donor doping is obtained in the surface by depositing a donor layer from the gaseous phase or by spraying or electrolysis and heating or applying an electric field to produce inwards diffusion. A further donor layer in which a metallic conductor is embedded is then alloyed to the heavily doped surface. Further diffusion is then produced by continued heating. The capacitors described may be utilized in phase modulators (see Group XL (c)). Specification 780,455 is referred to.

Abstract: 135,175. Barbet et Fils et Cie, E. Nov. 9, 1918, [Convention date]. Glucose.-In multiple-effect apparatus for concentrating grape juice under reduced pressure, different liquids are treated in each of the effects. The invention is particularly applicable to juices that have been treated with sulphurous acid, the juices being simultaneously concentrated to a boney and freed from sulphurous acid. Thus, white grape juice is concentrated in one effect at, say, 75‹ C. to produce a. honey for making jam, brandy, or liqueur wines, and other purposes where an alteration in the flavour and other characteristics is unobjectionable or desirable, while the juice of black grapes for use in making red wines is concentrated in the other effect at 55‹ C. or lower, 'in order to prevent coagulation of albumens and other changes. Acid potassium tartrate is separated in the course of evaporation. The plant consists of two effects, each comprising two evaporators, connexions being provided so that the plant can be operated as four evaporators in parallel or also as a triple or quadruple effect. Each of the two effects consists of tubular heaters D<1>, F<1> and separators E', G<1>.

[Class 40 (v)] The tuning of a high-frequency oscillating circuit is varied by the control voltage applied to a potential variable capacity for remote or automatic tuning, or volume or selectivity control. The minimum control voltage applied to the potential variable capacity is made high relative to the high frequency working voltages and the construction of the capacity is such that the variation of the control voltage is large to reduce the effect of the high-frequency amplitude variations in the tuning. The capacity may consist of electrodes movable by electro-static attraction with wide spacing or a relatively thick piezo-electric crystal. A resistance may be connected in parallel to those parts of the capacity to which the control voltage is impressed and the invention may be applied to a " single span " type of superheterodyne receiver.
