Patent GB-409345-A (GB)
Title: Improvements in or relating to punching machines for duplicating perforated record-cards
Filed: 1932-10-28
Abstract: 409,345. Punching statistical recordcards BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Oct. 28, 1932, No. 30240. Convention date, Oct. 30, 1931. [Class 31 (ii).] In a machine for duplicating statistical recordcards with a row of punches controlled by hole reading devices and a feed mechanism for stepping a blank card past the punches and a master card past the hole reading devices whenever a punching operation is performed, means are provided which cause the cards to skip blank columns of the master card without the use of a skip-bar. A relay coil 73 tends to initiate a feeding operation but is prevented from doing so whenever a brush 12. closes a circuit through a card. As applied to a machine of the type described in Specification 362,529, the cards are fed by rack and escapement mechanism under a row of punches 36 and a row of brushes 12. Each interposer is moved by a magnet 35 and the punches are operated by a plate 39 actuated by a magnet 43. When a brush meets a hole, circuit is closed through line, contacts 78, contacts 64, 62, coil 73 and line 74. The contacts 78 are closed during duplication but are opened during restoration of racks to prevent closing of circuit through the brushes during restoration. Contacts. 64, 62 normally are closed. The magnet 35 is energized and on movement of the interposer a bail 40 is rocked to close contacts 42 completing circuit through the punch actuating magnet 43 depressing plate 39. A bail 49 beneath the interposers rocks a shaft 53 to actuate the escapement. The brushes 12 are mounted on a rocker actuated by a magnet 21 and contacts 34 are closed when a master card is inserted into the machine, contacts 77 normally are closed but are opened when the card racks are restored. The relay coil 73 controls normally closed contacts 75 in series with contacts 76. The contact 62 makes contact with a contact 63 before it breaks contact 64. In operation, when a brush registers with a column containing a hole, contacts 62, 64 close and circuit is completed through magnet 35 and coil 73 before circuit through contacts 62, 63 and coil 73 is broken. The punching operation then takes place and contacts 62, 63 close. If the next column on the master card is blank, no brush completes the circuit and the machine normally would stop. The coil 73, however, is de-energized and contacts 75 are closed to complete circuit through contacts 76, 75 and magnet 43. The magnet 43 depresses plate 39 which engages a space interposer 82 and rocks the bail 49 to actuate the escapement. This opens contacts 62, 63 and coil 73 is reenergized and opens the contacts 75.

Title: Process of preparing voluminous artificial silk from viscose
IPC: D01F2/08
Filed: 1929-10-05
Abstract: Artificial silk of the hollow filament type is prepared by employing as the spinning solution unmatured or feebly matured viscose of normal composition and of substantially normal viscosity and in which has been dispersed a small quantity, not exceeding 0,1 per cent, of naphthalene, nitronaphthalene, camphor, anthracene, or mixtures of two or more of such substances.  The large volumes of gases produced from such viscoses during spinning are relied on to produce the desired inflation of the filaments, the added substances acting as nuclei for the formation of the necessary bubbles of gas.  The preparation of the added substances in the dispersed form may be carried out in the viscose or before addition thereto; thus, if naphthalene is used, the required fine dispersion is obtained by pouring a solution of naphthalene in acetic acid or pyridine into an aqueous saponine solution.  In an example, the coagulation bath contains sulphuric acid and sodium, magnesium and zinc sulphates. Specification 253,477, [Class 2 (ii), Cellulose &c.], is referred to.
