Title: Process for improving plates having a wooden outer surface by hot-pressing with the use of surface improving media
IPC: B32B29/00
Filed: 1932-12-16
Abstract: The surface of plates with a wooden surface (which may be covered with a thin paper layer) and consisting of one or more layers is improved by treating the plates with a solution of an artificial resin or mixture of artificial resins to which a plastifier has been added, drying them, and finally hot-pressing them between polished metal plates under a pressure not exceeding 25 Kg./cm.2.  The uniting of the individual layers to a unitary whole is effected simultaneously with the improving of the external surface by first treating the layers with the resin composition and drying them.  The temperature of the hot-pressing may be 150-170 DEG  C.  Phenol- or cresol-formaldehyde resins may be employed together with plastifiers such as castor oil, copal or artificial resins which do not harden completely, and preferably, a small amount of stearic acid.  The external wooden surface may be subjected to a preliminary pressing treatment, this treatment if desired, being preceded by treatment with hot water or steam under pressure, before the main process is carried out.  The invention may be applied to the production of ply-wood with three or more wooden layers, a thin layer of paper also impregnated with the artificial resin being arranged between the layers of wood. Products containing two external wooden layers and intermediate layers of paper, cardboard, asbestos or linen may also be prepared.  Coloured products may be obtained by adding colours or pigments to the artificial resin solution or by pressing on the surface of the product a thin coloured paper impregnated with artificial resin, the paper remaining attached to the wooden surface. Similarly, a paper impregnated with the artificial resin which exhibits an imitation of a different material, e.g. a more expensive wood, can be pressed on the surface or the original pattern may be preserved while pressing on to the surface a thin transparent layer of silk paper impregnated with the resin.  The wooden surface may be treated with a coloured fatty lacquer, e.g. linseed oil copal lacquer and after drying treated with the artificial resin and pressed in the manner above described. Specification 356,769 is referred to.

Resistance furnaces.- A furnace or muffle has its top, bottom, and side walls lined with removable heaters, the top and bottom heaters being supported independently of the side heaters, while the heaters for the side walls and bottom are reversible. In one form of furnace, grooves 12, 13 at the top and bottom of the side walls receive the edges of heating plates 10. These plates are cut away on both faces near the edges, to form seatings for side heating plates 9, all the plates being thus reversible so that the coiled or other resistances, which are placed in undercut grooves, may be exposed or covered. The top and bottom plates may be interchanged, as also may the side plates. In another form, front and back heating plates are also provided, and the top heater is removably held by a hinged cover. In a third form, a hinged arched cover and a similarlyshaped top heater, with exposed or covered resistance, are provided. The top heater is held by a removable annular flange on the cover, and may have a span greater than the space between the side heaters, in order to accommodate a crucible. The heating plates in any of these forms of furnace have the walls' between' the grooves cut away at alternate ends, so that the bights of the resistance do not project. Suitable materials for the heater plates are fused, semifused, and calcined alumina, magnesia, and zirconia, silica, and porcelain; these are stated to be good conductors of heat.

Patent GB-786037-A (GB)
Title: Improvements relating to typographical machines
IPC: G06F3/02
Filed: 1950-06-23
Abstract: 786,037. Typewriters. DIRKS, G.. June 23, 1950 [Oct. 1, 1948], No. 37218/54. Divided out of 786,021 [Group XIX]. Class 100(4) A typographical machine comprises means for recording. typographical matter as signals on a storage, means for recording separately corrections of the original matter, and sensing means, controlled selectively by signals in the storage, for reading the stored original matter .and the correctioms in the sequence necessary to reproduce a corrected text. As described, a printing device 1 of the type described in Specification 786,022 is movable horizontally along a slide 2 by a motor 5 and vertially on slides 4 by similar means. It is controlled by data signals from a magnetic drum 9 - one track of the drum for each line of type - and any line may be examined before printing by displaying it on a cathode-ray-tube indicator 8. The tracks bearing the original data are sensed by a pick-up head 17. Fig. 3. which is movable axially of the drum. Another head 27 senses auxiliary tracks bearing signals indicating where corrections are required, while three further heads 33, 34 and 35 are used for sensing the actual corrections or additional matter. During the rapid rotation of the drum the separate digit signals in a track are selected by an inductive distributer corriprising coils 15, 16 which move angularly, independently of the drum speed, in synchronism with the printer 1. Signals picked up by the head 17, Fig. 2, are passed by a pentode 13 when a gas tube 14 is rendered conductive by the coils 15, 16 and passed to the printing device through a coriverter of the type described in Specification 786,041 [Group XIX]. If, however, a signal is picked up by the head 27 a corresponding pulse is developed across the primary winding 28 of a further inductive distributer which, via secondary windings 29, 30 or 31, fires one of a trio of gas tubes 24, 25, 26 according to whether the signal is received in the first, second, or third phase, respectively, of rotation of the drum. Energization of an associated relay 21, 22 or 23 closes the circuit for a sensing head 33, 34 or 35 and breaks the circuit of the head 17 at contacts 18, 19 or 20 respectively. Thus the signals from the selected correction track on the drum are fed through to the printer in place of the original signals. Various modifications and alternative arrangements are suggested, including the use of step-by-step moving magnetizable tapes as described in Specification 786,034 [Group XIX] instead of the magnetic storage drum. Specifications 786,033, 786,038, and 786,039 [Group XIX] also are referred to.
