April 21, 1933, No. 11673. Drawings to Specification. [Class 40 (i).] In a system in which descriptions and destinations of trains are transmitted from one station to another to control indicating devices, if various parts of a train have different destinations all the destinations are transmitted, the destinations being shown sequentially as the various parts of the train are removed. As described a train consists of three light engines and the destinations of the engines are transmitted by impulses and are stored on switches of the step-by-step type, a further impulse indicating that the train consists of light engines. The indicator shows the first destination received and that three light engines are coming. When the first engine is removed from the train a pulse, received over a special wire, alters the destination indications from the first to the second and alters the description from three to two light engines. When the second engine leaves the train a second pulse is received which alters the destination indication from the second to the third and cancels the " two " indication. The indications are removed and the apparatus homed by the operation of a key or by the receipt of a pulse over a further wire. Descriptions of a second train may be received and stored on a second register device, the descriptions being shown as those for first and second trains. When the description of the first train has been removed the description of the second train moves up to the first train description panels. Should a train have two destination descriptions only the third destination switch is used to record the train description.

Title: Improvements in or relating to the production of patterned cellulose fabrics
IPC: D06Q1/02
Filed: 1939-04-19
Abstract: 528,049. Parchmentizing fabrics. TENNANT, W. J. (Akt.-Ges. Cilander). April 19, 1939, No. 11839. [Class 15 (ii)] A cellulose-containing fabric is locally printed with a celluloid-containing composition comprising a white pigment, and after drying the printed portions, the fabric is treated with a transparentizing swelling agent, which has no effect on the celluloid composition, whereby a pronounced contrast between the printed portions and the transparentized fabric background is obtained. The swelling agent may be a mineral acid. The reserve completely protects the printed portions of the fabric from the action of the acid. In an example, a mercerized cotton fabric is printed with a paste comprising titanium dioxide, alcohol, a high boiling solvent for celluloid, polyglycol, and a solution of celluloid in volatile solvents. The composition is dried on the fabric, and then the fabric is treated with sulphuric acid at 0‹C. for 12 seconds. The sulphuric acid is washed off and the fabric is then subjected to mercerization with caustic soda. Instead of titanium dioxide, there may be used zinc white or other white pigment.

Title: Improvements in or relating to machines for grinding, polishing and similar treatment of work-pieces
IPC: B24B5/36
Filed: 1933-04-24
Abstract: 418,742. Centreless grinding. ROBLING, F., 145, Broekslootkade, Rijswijk, Holland. April 24, 1933, No. 11990. Convention date, April 23, 1932. [Class 60.] A machine for grinding or polishing straight or curved work pieces with a circular or non- circular cross-section has the work supported in at least three points of its circumference by means which rotate around the work, such means consisting either of tools only or of tools working in conjunction with one or more supporting members. In one form, two grinding discs a mounted on a rotary plate d cooperate with a steady roller b carried by a member A sliding in a sleeve i secured to the plate, the work c being shown as a curved rod of circular section. The plate d is mounted on a hollow shaft d' and is driven for the planetary movement of the wheels round the work by means of a gear e. Each grinding-spindle o is driven by toothed gearing m, n and shaft l from a gear k, one of which engages directly and the other indirectly through an idler w with a stationary gear j, the grinding wheels being thus rotated on their axes in opposite directions. Casings h enclosing the grinding wheel spindles and their driving gears m, n are secured to bushes mounted in sleeves g and carrying tooth segments u engaged by racks x adjustably mounted on a slide s. In order resiliently to force the tools and guide roller equally against the work piece, a rod r is constrained to move axially in the hollow shaft d<1> by means of a lever p weighted at v. The member r engages one arm of two bellcranks H, one of which is connected to the slide s to impart inward pressure to the grinding wheels and the other of which is connected through a slide s<1>, spindle z<1> and lever mechanism E, B to the member A carrying the guide roller which is thus pressed towards the work with the same force as the tools. The pressure between the tools and work may be adjusted during the working operation by varying the position of the weight v. Instead of the yieldable pressure on the work piece obtained by use of the weight v, the free end of the lever p may be rigidly guided for accurate adjustment of the wheels and guide roller. In order to adjust the grinding discs for work of different sizes the casings are adjusted by screws z which move the racks relatively to the slide s. The adjusting spindle z<1> is used for setting the guide roller b.
