Abstract: 851,604. Statistical record cards. IMPERIAL CHEMICAL INDUSTRIES Ltd. Oct. 16, 1957 [Oct. 17, 1956], No. 31591/56. Class 106 (1). A record sheet is prepared in certain areas with marks which are masked by an opaque sheet, required marks being exposed by removing the mask in the corresponding area by mechanical pressure or abrasion, by heat or by solvent action. The marks may be printed in ordinary ink in the radial form shown in Fig. 1, the three groups in each line corresponding to the three denominations of a number. The marks are then obscured by a mask of pulverised polymethyl methacrylate and faint guide marks are applied as in Fig. 2 to indicate the positions of the underlying marks. The appiopriate digit lines in each group are revealed by applying a felt-tipped pen soaked in carbon tetrachloride, thereby dissolving the mask in the area of the desired mark as shown in Fig. 3. An area much greater than the mark may be affected by the solvent, but not large enough to reveal adjacent marks. The Provisional Specification describes a record sheet in which a mark is caused to appear by the interaction between two chemicals one of which is previously applied to the sheet in a pattern of marks e.g. as shown in Fig. 1 and the other of which is applied afterwards to the appropriate area to bring up the required mark. The pattern may, for example, be initially printed with an aqueous solution of potassium ferricyanide and the required mark revealed later by a solution of ferrous sulphate in acetone applied with a felt tipped pen. The mark then appears in blue. This matter is not in the Complete Specification.

Title: Improvements in the manufacture and treatment of artificial textile filaments of organic origin
IPC: D06M11/48
Filed: 1920-11-19
Abstract: So-called "staple fibre" which is obtained by cutting up filaments prepared from cellulose solutions, &c., is rendered non-inflammable by treating the formed filaments at a stage prior to the cutting up with fireproofing solutions such as are ordinarily employed in fireproofing textile materials.  The treatment may be carried out after the usual drying process, or in the case of viscose filaments optionally while the filaments are in the gel condition, or in the case of nitrocellulose filaments immediately after the denitration. According to examples, sodium tungstate is deposited on the filaments by treatment with a solution of this salt in acetic acid, and aluminium tungstate by treatment with a solution of aluminium acetate and sodium tungstate in acetic acid.  To waterproof the threads, an excess of aluminium acetate may be employed in the second case, or formaldehyde may be added to the bath; or the threads may be treated subsequently with formaldehyde.

Title: Method and apparatus for encoding asynchronous digital signals
IPC: H03M7/00
Filed: 1969-06-30
Abstract: 1279676 Digital transmission systems; multiplex pulse code signalling NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 30 June 1969 [9 July 1968] 32854/69 Headings H4L and H4P In a data transmission system binary data which is synchronous with clock pulses is transmitted as a train of pulses whose phase is indicative of the data bit state, the train including pulses indicative of the position of each bit transition relative to the two clock pulses spaced about the transition. In Fig. 1 for example, b and c represent phase-displaced pulse trains. Interval ts is the clock repetition period. When a data O-bit is to be transmitted pulse train b is sent and when a 1-bit pulse train c. Thus, for the data sequence 010 shown at a, portions A and C of d, except for P4, correspond to b, and portion B, except for P2, corresponds to c. Pulses P2 and P4, i.e. the pulses following the first pulse after a bit transition in a, take a state 0 if the transition occurred in the first half of a clock period ts, as does P4, or take a state 1 if the transition occurred in the second half, as does P2. In a practical arrangement, Fig. 2 (not shown), the binary data a, Fig. 4, is sampled by clock pulses to provide samples b. These are fed to an EXCL-OR gate which is also fed with pulse train c. The resulting signal d has the features detailed above and is transmitted. P5 and P6 indicate the times of the bit transitions. In the receiver, the received signal d is fed to an EXCL-OR gate together with a locally generated pulse train c. The output e of the gate enables an approximation of the original signal a to be generated. Instead of a single pulse indicating the transition position a plurality of pulses may be used. As applied to a time division multiplex system comprising m channels, Figs. 5-7 (not shown), a channel sampling pulse is applied to each of the m input channels in turn following each clock pulse. The samples from each channel are fed to a respective EXCL-OR gate together with the appropriate one of m phase-displaced pulse trains, each similar to c in Fig. 4. The outputs of the gates are fed to a common channel as a t.d.m. signal. The pulses on the t.d.m. channel in any two adjacent frames may consist of two adjacent pulses from the gate of the first channel, followed by two from the second channel, ..., followed finally by two adjacent pulses from the mth channel, Figs. 5c, 5d (not shown).

Abstract: 664,909. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Dec. 28, 1949 [Jan. 5, 1949], No. 33097/49. Class 106 (i). In a device for sensing discrete magnetized spots on a record member, e.g. a tape 10, comprising a sensing coil 13 in which a varying flux is produced by relative movement between the coil and member, a normally closed switch 20 is momentarily opened during the passage of a spot past the coil while a relatively high current is circulating, to produce a voltage impulse which is picked up, e.g. by an amplifier 17. As shown, gearing 22 ensures that a cam 21 opens the switch 20 in synchronism with the movement of tape 10, and the impulse then produced is sharpened by a capacitor 23. Data may be cancelled by reversing the polarity of the magnetized spots. In a modification, the coil 13 is transformer-coupled to two amplifiers responsive respectively to impulses produced by magnetized spots of opposite polarity.

Title: Fluid bed trap for conversion systems
Inventor: MOSER JOHN FREDERICK
IPC: B01J8/18
Filed: 1958-10-21
Abstract: In the production of gaseous unsaturated hydrocarbons and coke from hydrocarbon oils by contact with a dispersed suspension of hot particulate solids, the solids are separated from the gaseous product which is then quenched to prevent further reaction without condensing more than a minor amount of the products and passed into a dense, fluidized bed of particulate solids at about the same temperature to further remove solids from the gaseous products.  The particulate solids used in the process may be coke or silica and the same solid is preferably used in the fluidized bed.  The primary gas-solid separation zone may be a cyclone.  The quenching may be effected with a fraction of the liquid products, the quenching being to such a temperature that not more than 10% by weight of the product is condensed.  Reaction conditions may be 1100-1800 DEG  F. with a gas velocity in the reactor of 5-150 ft./sec., the contact time being 0.01-5 secs.  The gas velocity in the fluidized bed may be 0.5-4 ft./sec.; solids are withdrawn from the bed and the cyclone, reheated and re-cycled to the reaction.
