Patent GB-387808-A (GB)
Title: A time recorder for use in connection with electrical tramway, railway, and like systems
IPC: G07C1/08
Filed: 1931-12-21
Abstract: 387,808. Recording-apparatus. GLEDHILL, A. H., Trinity Works, Halifax, Yorkshire. Dec. 21, 1931, No. 35236. [Class 106 (iv).] A device for recording the time at which a train or other vehicle passes a given point or points on a route comprises a marking element adapted to follow a spiral path on the face of a clockrotated disc chart the element being caused to mark the chart by electromagnetic means when the vehicle passes the predetermined points. In the form shown in Figs. 1 and 4, the marker is constituted by an edged plate A arranged radially to a clockdriven disc B and carried on a lever D forming part of a hammer C pivotally mounted at the lower end of a link E. The link E supports a frame F on which is mounted an ink ribbon mechanism G guided in front of the hammer C ; the link is adapted to receive a radial movement by means of an arm H operated by a snail cam J driven by the clockwork. The tail of the hammer lever D carries a roller d and is adapted to co-operate with a plate L on the armature M of an electromagnet N. When a vehicle passes a predetermined point a contact is closed to energize the magnet, the armature of which operates the hammer lever to cause the marker to make a radial line on the record disc, the marks taking up a spiral formation.

Abstract: 618,739. Regulating. SIMMS MOTOR UNITS, Ltd., DUNN, H. G., and HULL, C. H. Nov. 27, 1946, No. 35241. [Class 7 (vi)] Rotation of an eccentric 5 by means of a rod 21 connected to a bellows 12 subject to boost pressure adjusts a fuel injection pump control rod 1, actuated through a member 2 connected to an accelerator pedal or governor, in accordance with the boost pressure. The lever 1 is pivoted to an eccentric pin carried by a block 5 rotatable in a bore 6 in member 2 and to which is fastened the lever 21, rotation of which causes the pin to move the member 1 relative to member 2. At idling the pin is near its dead-centre position with respect to the axis of the members 1, 2, so that pressure fluctuations produce very little movement of the member 1. A distance-piece 22, which may be adjustable, limits the contraction of the bellows 12, which may be replaced by a spring-loaded plunger or diaphragm. A crank may also replace the eccentric 5.

H., 65, Humber Road, Blackheath, all in London. Dec. 17, 1932, No. 35827. Addition to 378,585. [Class 40 (iv).] In a system employing a trunking system as described in the parent Specification, a discriminating relay PA, for example, a wiperchoosing relay, connected between earth and the incoming a-wire is operated or not according as seizure of the circuit occurs over the loop or over the b-wire only, the circuit over the a-wire being open in the latter case so that the arrangement is independent of any difference of earth potential which may exist between two exchanges. The repeater shown is seized over the incoming loop or over the b-wire and in the former case relays P, A, operate in series to complete the outgoing loop and operate the discriminating relay PA. In the latter case relay A connects ground from contact p1 to the outgoing b-wire to operate relay AA, and the operation of the release relay BA short-circuits PA to prevent subsequent operation. At the first impulse, relay PP operates to complete the loop, and impulses are repeated by relay A. When the called subscriber replies, polarized relay D, the line winding of which is connected in series with a rectifier R, operates and energizes relay DD (i) which disconnects relay J, during the release period of which boostermetering battery BB is connected up. If a busy signal is sent back, the first release of relay I releases relay J, and on the next operation of I, relay BR energizes to connect up busy-flash lead BF and to operate relay HA which releases the remainder of the connection.

Title: Process for manufacture of resinous condensation products and varnishes
IPC: C08G8/28
Filed: 1920-12-31
Abstract: Synthetic resins are produced by effecting the condensation between phenols and formaldehyde of its polymers or hexamethylenetetramine in the presence of vinyl compounds or their polymerisation products, or by adding the vinyl compound or its polymerization product to the phenol-aldehyde compound.  Suitable vinyl compounds are vinyl acetate; chlor-, oxy-, amino-, and arylacetic esters; propionic esters; polymerized vinyl esters; vinyl halides, e.g. vinyl chloride; and vinyl ethers, such as vinyl ethyl ether or vinyl propyl ether. The reaction is accelerated by the addition of small quantities of an organic anhydride, or superoxide, or non-explosive ozonide.  The products are used for the preparation of varnishes; they take up certain oils and esters to form non-fragile products capable of cutting and moulding.  The raw materials may be dissolved in a low-boiling solvent, and used for the impregnation of wood, paper, cellulose, asbestos, graphite, &c., the solvent being evaporated at a low temperature.  The condensation products can be stuck together by softening their surfaces with acetone or chlorinated hydrocarbons, e.g. chlorbenzene, dichlorhydrin, epichlorhydrin, or mesityl chloride.

Patent GB-449183-A (GB)
Title: Improvements in or relating to the production of cellulose esters
IPC: C08B3/08
Filed: 1934-12-21
Abstract: Secondary cellulose propionates are prepared by reacting cellulose or a low substituted cellulose derivative with propionic anhydride in the presence of a catalyst such as sulphuric acid with the formation of a primary tripropionate soluble in acetone and in benzene, and hydrolyzing the primary ester formed until the product obtained is soluble in acetone and insoluble in benzene and also if required insoluble in butyl acetate.  Suitable low substituted cellulose derivatives are ethyl cellulose, benzyl cellulose, crotyl cellulose, cellulose acetate, and cellulose nitrate.  The cellulosic material may be given a pretreatment, e.g. with propionic and sulphuric acids, or with formic acid; in the latter case, from 3 to 18 per cent of formyl radical may be introduced into the cellulose, but this is removed in the subsequent hydrolysis step.  Other suitable pretreatments comprise treatment with caustic soda followed by removal of alkali and water by means of methanol and benzene; treatment with propionic acid or anhydride alone; treatment with a mixture of propionic acid and anhydride.  In the esterification step other solvents than propionic acid may be used, e.g. methylene chloride, ethylene dichloride, dichlorethylene, and chloroform.  The following examples are given; (1) Cotton linters are impregnated with propionic acid containing sulphuric acid as catalyst, propionic anhydride is added, and the mixture allowed to stand until esterification is complete.  Propionic acid (60 per cent) and sulphuric acid are added and hydrolysis is allowed to proceed until a sample precipitated from the mixture is found to be insoluble in benzene but still soluble in butyl acetate and acetone; (2) Cotton linters are pretreated with propionic acid and sulphuric acid, esterified by adding propionic anhydride and propionic acid, and hydrolyzed as in the first example; (3) A primary cellulose propionate is prepared as in the previous example and hydrolyzed by stirring in propionic acid (60 per cent) and sulphuric acid.  The product is insoluble in benzene and butyl acetate but soluble in acetone, glycol mono-methyl ether and dioxane; (4) Cotton linters are pretreated by means of formic acid and zinc chloride, and the dried pretreated material is esterified by adding propionic anhydride, propionic acid and sulphuric acid. Hydrolysis of the primary ester is carried out by adding 60 per cent propionic acid and sulphuric acid; (5) Cotton linters are pretreated with formic acid in the presence of sulphuric acid, dried, and esterified as in example (4).  The ester is then hydrolyzed until a precipitated sample is just insolucle in butyl acetate but still soluble in acetone.  The hydrolyzed esters may be used in the manufacture of films, plastics, coating compositions, artificial fibres and bristles, and safety glass.  A suitable solvent mixture for the esters consists of acetone-ethyl alcohol (or ethyl acetatemethyl alcohol) and butyl acetate (or amyl acetate, benzene, toluene, ethylene dibromide, ethyl butyrate).
