Patent GB-289347-A (GB)
Title: Liquid fuel for use in internal combustion engines and process for the production thereof
IPC: C10L1/22
Filed: 1926-10-27
Abstract: 289,347. Somerville, P. G., and Hoffert, W. H. Oct. 27, 1926. Motor spirit containing a substantial proportion of resin, forming ingredients is stabilized against the production of resins or gums on storage or combustion by the addition or adjustment therein, while containing little or no actual resin, of a proportion of an aromatic amine, nitrocompounds, or phenol, found by previous test to be effective. 0.05 per cent is typical. Phenols, cresols, amino-phenols, nitro-benzene and aniline are specified as inhibitors. Fuels specified are motor-benzole, benzine, gasoline, petrol, cracked petrol, heavy oils and spirits obtained by low-temperature carbonization, and " Synthol." In examples, cracked petrol is treated with 0.05 per cent by weight of tri-cresol, crude benzol with 0.043 per cent of aniline. The fuel may first be entirely freed from inhibitor and the required proportion then added, or the alkali wash or other purification so conducted as to leave in the required amount of phenol or other inhibitor. It is stated that acids, aldehydes and mercaptains accelerate resinification, and that water, alcohols, ethers, thiophenes, and carbon disulphide have little or no effect thereon. The fuel is tested for stability by exposing samples to ultra-violet radiation for definite times in dishes with quartz covers placed in standard positions relative to the lamp and then evaporating the sample to dryness. The mount of radiation is estimated by exposing potassium iodide solution in a standard position and titrating the amount of iodine liberated. Specifications 10739/10, 11167/13, 105,490, 131,869, 140,041, 217,606, 245,281, 253,353, and 257,613 are referred to.
Patent GB-680633-A (GB)
Title: Improvements in or relating to teleprinting apparatus
IPC: H04L17/12
Filed: 1949-10-19
Abstract: 680,633. Printing-telegraph transmitters. SIEMENS & HALSKE AKT.-GES. Oct. 19, 1949 [Oct. 1, 1948], No. 26905/49. Class 40 (iii). In a printing-telegraph perforated-tape transmitter, the shaft which periodically actuates the transmitting contacts is rigidly or directly coupled to the driving motor and the transmission can be suspended although the motor is running by the actuation of short-circuiting contacts which bridge the transmitting contacts. The member which actuates the shortcircuiting contacts also controls the forward feed of the perforated tape. The shaft 1 which carries cams, such as 32, for operating the transmitting contacts 31, also carries a cam 2 which, during each revolution, moves a pivoted lever 3 to close the shorter-circuiting contacts 12 and to advance a ratchet wheel 5 connected to a pin-wheel 6 by which the tape 7 is stepped forward. When the control bar 8 is in its normal right-hand position, a projection 10 does not obstruct the movement of a lateral extension 11 on an arm of the lever 3. When the bar 8 is in its left-hand position, the projection 10 prevents the return movement of the lever 3 so that contacts 12 are maintained in the closed position and the tape-feed operation is suspended. The control bar 8 is moved to the left if the switch 13 is rotated anticlockwise to cut-out the motor, if the tape becomes too taut so that a frame 19 and connecting link 33 are moved to the left, if the tape breaks or becomes exhausted so that a bar 20 drops and rocks bell-crank 21, or if the motor has not attained normal running speed so that a pin 17 via a lever 18 holds the bar 8 in the left-hand position, and allows the bar to move to the right when normal speed has been attained. Additionally an armature 23, released by a magnet 22 when a break occurs in the operating circuit of the motor, moves inward to a position to engage under extension 11 of the lever 3. In a modification, Fig. 2, the transmitter can be switched out to allow reception from a distant transmitter, by means of a magnet 26 in the line circuit associated with a bar 25 so that signal interruptions when the end of the bar is in register with a recess in a cam 24 on the shaft 1 allows a detent 27 to release a member 28 which rocks a member 30 on the shaft of the switch 13 so that the control bar 8 is moved to the left to suspend the action of the transmitter. The lever 25 can be rendered inoperative by the movement of the member 30 in the anticlockwise direction to release the detent 27 from the member 28 which rotates underneath the end of the detent.
