Abstract: 708,233. Measuring radiation photo-electrically. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 18, 1952 [Nov. 19, 1951], No. 29085/52. Class 40 (3) In a device for deenergizing a relay 12 in the anode circuit of a thermionic valve 8 when a photoelectric cell 10 receives a certain light intensity, the grid of the valve, which is A.C. fed from a transformer 1, receives during those half cycles when its anode is positive with respect to its cathode a positive voltage from adjustable resistor 4 and a negative voltage produced by charging a condenser 6 through photocell 10 during the previous half cycle. Thus a particular value of illumination will hold valve 8 blocked during its positive half cycle and relay 12 unoperated. If the current of photo-cell 10 which is gas filled varies linearly with anode potential the resistors may be so chosen as to make the apparatus independent of voltage fluctuations. Further amplifying stages may be added; for example, a thyratron may have its grid connected to the anode of valve 8, coil 12 being replaced by a resistor and the coil inserted in the thyratron anode circuit.

Title: Process for the production of knock-stable motor fuels by destructive hydrogenation of liquid hydrocarbons
IPC: C10G47/00
Filed: 1934-10-11
Abstract: Knock-stable motor fuels are obtained by the destructive hydrogenation of liquid hydrocarbons containing constituents boiling above 200 DEG  C. and rich in cyclic hydrocarbons, e.g. middle oil obtained from bituminous coal, by subjecting the initial materials to destructive hydrogenation in presence of a strongly hydrogenating and splitting catalyst so that a strong formation of benzines occurs, but at least 10 per cent of constituents boiling above 200 DEG  C. remain in the liquid reaction product, and subjecting these constituents at high temperatures to a further destructive hydrogenation in presence of a dehydrogenating and splitting catalyst so that benzines containing aromatic constituents are obtained, and mixing the benzines obtained in both stages.  In the first stage sulphides, e.g. tungsten sulphide, are specified as catalysts and the initial material is treated at 390--440 DEG  C. for 40--80 seconds with a circulation of 3--6 cubic metres of hydrogen per kilogram of initial material. In the second stage (aromatization stage) oxides of the 6th group mixed with zinc oxide are specified as catalysts and the material is treated at 450--600 DEG  C. for 80--120 seconds with a circulation of 1--1,5 cubic metres of hydrogen.  Part of the product of the first stage may be recirculated to that stage.

Filed: 1931-10-22
Abstract: 383,724. Grinding. CHURCHILL MACHINE TOOL CO., Ltd., Broadheath, near Manchester, and ASBRIDGE, H. H., Claremont, Washway Road, Ashton-on- Mersey. Oct. 22, 1931, No. 29327. [Class 60.] Driving and feed devices.-Feeding motion is imparted to the grinding-head of a precision grinding-machine, either at each pass of the work-table, or intermittently when the table is non-reciprocating, by means of a roller type ratchet, a second roller type ratchet being provided to prevent reverse movement. The grinding-head is fed by screw and nut, or other gearing operated by a shaft a driven by spur gearing b, c from a shaft d, which carries a hand-wheel e and a disc f having a recessed periphery receiving a driving ratchet roller g and a retaining roller h. On the shaft a are keyed two discs i, j between which is an internally toothed ring k, having a lug m thereon and angularly adjustable by a pinion o on a spindle n carried by the discs i, j. Mounted rotatably on a sleeve g, serving as a bearing for the shaft a, is a collar r, a spring-pressed pad s<1> serving to prevent unintentional rotation of the collar, and on the collar are teeth s; the collar is rotated by the lug m which comes into engagement with an adjustable slide t on the collar, a collar u serving to limit rotation of the collar r in a counterclockwise direction. The teeth s engage teeth x on a housing y journalled on the shaft d, and formed at z to engage the roller g to limit its movement. The housing y carries a plate 2 between which and the disc f the roller h is situated, and movable, by means of a handle 5 about the boss of the housing y, is a part 4 carrying a pin 3 serving to move the roller h into a position where it cannot be wedged between the disc f and the plate 2. The roller g is wedged against the disc by a plate 7 carried by a frame 30 oscillated about the shaft d by a link 8, and the roller is pressed by a spring g<1> towards its wedging position. The link 8 is movable through levers &c. by stops 11 on a rod 12 movable with the work-table, or is moved by an eccentric 13 movable to engage a pad 15 beneath the link, and oscillation of the plate 7 causes rotation of the disc f, reverse motion thereof being prevented by the roller h. In order to adjust the amount of movement of the plate 7 for each feed, the frame 30 has a part 23 carrying an adjustable crank pin 22, which rests on a fixed bracket and so limits the downward movement of the link 8. As the feeding movement proceeds, the lug m is brought, by the rotation of the shaft a, against the slide t and rotates the collar r, thus causing rotation of the housing y and moving the part z so as, step by step, to diminish the movement of the roller g and thus the feed, and finally to move that roller to the non- wedging position, where the feed ceases. In order to reset the parts, the handle 5 is moved to render inoperative the roller h, when the hand-wheel e may be operated.
