Abstract: 503,435. Drawing tubes. LENNIE, D. C. Nov. 9, 1937, No. 30682. [Class 83 (iv)] A draw bench 1 comprises a tube drawing die (not shown), a continuously driven draw chain 3, a dog 4 adapted to be connected to the chain to pull the tube 5 through the die and to disconnect itself from the chain when relieved of load and a power driven roller 6 adapted to propel the tube backwardly to initial position, the dog being mounted on a carriage 9 provided with a trip device co-operating with a stop 11 so as to cause the dog to release the tube at a predetermined point in the backward travel of the tube. The dog has jaws 7 for gripping the tube and engages the chain 3 through a gravity loaded bellcrank lever 12 which automatically, disengages the chain when the load is removed, that is, when the tube has passed through the die. The backward movement of the tube is initiated by a pedal 17 which depresses a roller 16 to bring the tube into contact with the driven roller 6. The jaws 7 of the dog are opened by the action of the adjustable stop 11 to release the tube during its backward travel.

Leech ropes 32 are sewn to the webs near their edges and to these ropes are secured annular members 36 which pass around and slide upon pairs of cables 34. These cables and the leech ropes extend between brackets'33 at the two feet of each frame. The covering 31, the sides of which are weighted, is hauled into position by halliards 38, 41, 42, which pass around pulleys on the portal frames and which carry shackles 37a which engage with the cables 34. The lower ends of the halliards are secured at 40a to the bases of the frame supports 6.

Title: Production of low boiling point saturated hydrocarbons from heavy hydrocarbon oils
IPC: C10G11/02
Filed: 1921-11-21
Abstract: 174,574. Chemical Research Syndicate, Ltd., (Assignees of Ramage, A. S.). Jan. 28, 1921, [Convention date]. Drawings to Specification. Hydrocarbons, cracking.-In preparing low boiling hydrocarbon oils from heavy fuel oils, crude oils &c., the vapours from the oils are mixed with steam and passed over heated ferrous oxide, the proportions of oil vapour and steam being regulated to avoid oxidation or reduction of the oxide. The treatment may be effected by passage through tubes packed with ferrous oxide, which may be prepared by reducing ferric oxide in the tubes. The oil vapours and steam are supplied to the tube through separate orifices at one end. The proportion between them may be varied by varying the pressure of the steam. To obtain a spirit suitable for use as a fuel for internal-combustion engines, the tubes are heated at the inlet end to 500‹ C. and at the outlet to 620‹ C. To obtain a lighter spirit the tubes are heated at the inlet end to 600‹ C. and at the outlet end to 700‹ C.

Title: Data entry system
Inventor: IGEL J J
IPC: G06K1/06
Filed: 1970-06-26
Abstract: 1,270,366. Data storage; selective signalling. INTERNATIONAL BUSINESS MACHINES CORP. 26 June, 1970 [3 July, 1969], No. 31109/70. Headings G4C and G4H. A data entry system comprises means for generating data characters each representing a selected character, logic means to enter the data characters in sequential positions in a data store and to remove a flag bit denoting a vacant position from each position storing data, and backspace means to replace the flag bit in one or more positions in the reverse sequence to that in which the positions were entered starting from the last entered position to enable data characters already entered to be replaced by new data characters. Data characters (including space characters) are entered from a keyboard via an entry register into the data store which is a recirculating loop including a magnetostrictive delay line and a shift register. The loop holds 96 "columns" (in series) each consisting of seven 8-bit character positions. Of each 8 character positions, one is for receiving a character from the keyboard and includes a keyboard flag bit position, two can receive characters from the keyboard character position for punching and printing on a card and include flag bit positions, and the other four are programme characters one of which can be selected by one of four programme keys on the keyboard. Initially the keyboard flag is inserted in each column, and each character entered from the keyboard is inserted into the first column with the flag present, this flag being deleted. The column the system is at, in this sense, is displayed. A field-erase key, in dependence on the positions of a lower-shift key and a programme on/off switch, causes the keyboard flag bits to be reinserted from the position the system is at, back one column or back to the first column of the current field (defined by an end-of-field bit in the selected programme character), or back to the next preceding space character (detected by comparing the shift register with the entry register, now empty) in the keyboard character positions. A record erase switch inserts the keyboard flag in every column. Backspacing by one column involves comparison of a clockdriven column counter with a register normally updated with the contents of the column counter, the updating having been inhibited since backspacing is required so that the register indicates the preceding column position. The register also controls the display of the position the system is at (see above). The programme characters also include bit positions for causing skipping during backspacing.

The kilo and gramme scales may be carried on an aluminium strip 19 secured to the scale rail between the sliding weights. The arms 9, 10 may be bent to allow the poises to move past them up to stops provided on the arms.

Filed: 1931-11-11
Abstract: Artificial silk, films, and the like of reduced, subdued or modified lustre are produced by the dry or wet spinning process from spinning solutions containing a titanic acid, for example H2TiO3 such as is prepared by the double decomposition of sodium carbonate and potassium titanium oxalate.  The titanic acid, which may be present to the extent of from 0,1 to 10 per cent of the weight of the cellulose or cellulose derivative forming the base of the spinning solution, may be incorporated by any suitable means such as by working up with the solvent, or a portion of the spinning solution itself, or the cellulose acetate or other base used before the solution is actually made up.  The titanic acid may be ground, if desired in the presence of heavy white mineral oil, olive oil, castor oil, turkey-red oil, diethylene glycol, or the like, so that the particles have a diameter of 0,1 to 5, and preferably less than 1 to 2 microns. The process may be applied to the manufacture of filaments or other products, from viscose or other aqueous solutions, or solutions or cellulose esters, ethers, or ether-esters.

[Class 69 (i)] [See also Group XIX] Measuring-apparatus comprises a movable wall acted on by a force or liquid or gas pressure due to what is to be measured and oppositely by pressure in a space, the latter pressure being controlled by two rigidly connected valves, one controlling a port leading to a source of pressure or suction, and the other a port leading to the atmosphere ; the valves are normally maintained closed by the pressure of the measuring medium and the atmosphere port moves with the movable wall. In the fluid meter shown, bellows 4, 5 are closed by plates 6, 7 and connected by a tube 8 in which a throttling member 11 is disposed. A bellows 12 is secured at one end to the plate 6 and at the other to a bracket 13 adjustable along the longitudinal axis of the meter. The entry of air to the bellows 12 from a pipe 14 and the escape through an outlet 15 are controlled by rigidly connected valve members 18, 19 acted on by a spring 20. A pipe 16 leads to a pressure gauge. Greater sensitivity is obtained by providing one or more small grooves in one valve or its seat so that it leaks slightly. In modifications, the throttling member 11 is slidably mounted and acted on by a spring. When the invention is applied to liquid level indicators and altimeters, the bellows 5, tube 8, and member 11 are dispensed with. In a further form shown in Fig. 4, the pipe 14 is connected to a source of suction.
