Abstract: 1,104,673. Photographic roll-film. EASTMAN KODAK CO. June 24, 1965 [June 24, 1964], No.26744/65. Heading G2A. A leading or trailing portion of a photographic film strip has projections formed on the face of the film, which, when the film is wound on a seal, cause adjacent turns to be laterally misaligned, so that their edges are staggered to fit snugly against the seal flanges and thus inhibit edge fogging of the film. The projections may be provided by forming slanted fluting in both margins of the film or in the centre. Alternatively, spaced portions of the rims of the film are bent up.

Title: Improved system for regulating the quantity of liquid in a container
IPC: G05D9/12
Filed: 1948-10-15
Abstract: 663,643. Automatic liquid level control systems. ENNIS, G. H., and FUNK, R. V. Oct. 15, 1948 [Nov. 1, 1947], No. 26863/48. Class 38 (iv). In an oil-water separating tank, the position of the liquid inter-plane is detected through the variation in the value of a capacitor or inductor caused by the movement of the interplane which effects operation of the outlet valve controlling the water content of the tank. As shown, in tank 26, when the emulsion zone 25, between the oil and water, moves relative to the electrode 24, the change in oscillatory current in the circuits 52, 53, 61 causes the relay 44 to connect the motor 39 to the source 42. The pump 33 raises the pressure in compartment 35 and the piston 29 is forced down against spring 32 so as to open valve 16 and reduce the volume of water in 26 and hence lower the zone 25 below the electrode 24. In order to prevent the removal of oil from the tank, the passage of oil in outlet pipe 14 interrupts the circuit of relay 46 between electrode 50 and 14, and the coil 38 is de-energized and the valve 37 opens to release the pressure in 35, whereon valve 16 closes. In an alternative form, not shown, the capacitative detector 24 is replaced by an inductor which is progressively shorted as the water rises.

Title: Apparatus for producing high-tension alternating current from a direct current source, especially for luminous tubes, medical apparatus and the like
IPC: H02M7/62
Filed: 1933-10-04
Abstract: 426,487. Converting. STIEGLITZ, I. LOW-, 150, Vorgartenstrasse, Vienna. Oct. 4, 1933, No. 27322. Convention date, Oct. 4, 1932. [Class 38 (ii)] [See also Group XXXVII] A vibrating electro magnetic interrupter for use in apparatus for producing high tensior A. C. for luminous tubes medical apparatus, &c from a direct - current source comprises a re silient tongue which interrupts two circuits and on which the twc contacts controlling the circuits are mounted, the interrupter contact for the operating electromagnet being resilient relatively to the tongue whereas the contact for the circuit of the direct current source is rigid relatively to the tongue and is situated so near the point at which the tongue is clamped that after the rigid contact bears against its mounted contact the free end of the tongue can swing out beyond the contacting position under the influence of the electromagnet thus increasing the contacting pressure of the rigid contact. As shown in Fig. 1 the magnetic reed 3 is clamped at one end between brass plates 2 with an intermediate layer 4 each side of resilient or yieldable insulating material. The circuit of the operating electromagnet 16 is interrupted between an adjustable relatively fixed contact 15 and a yieldable contact 11 carried by the reed. On the opposite side the reed carries a rigid contact 9 adapted to engage periodically a relatively fixed but adjustable contact 13 so supplying current impulses to the primary winding 25 of a transformer the secondary winding 24 supplying the A.C. output at terminals 28. If desired contacts in the transformer circuit may also be arranged at the opposite side of the reed for doubling the frequency of the A.C. produced. The rigid contact 9 is situated so near to the clamping point of the reed 3 that when the contacts 9, 13 are brought into engagement the upper part of the reed continues its vibration for some distance before it reaches its full amplitude. The action reinforces the contact pressure between contacts 9, 13, and produces a rapid make and break between them. In a further modification, Fig. 6, (not shown), several vibratory tongues may be arranged to be operated by a single electromagnet the circuit of which is interrupted by contacts controlled by one only of these tongues.

Abstract: 322,829. English Electric Co., Ltd., and Hassler, E. H. H. Sept. 24, 1928. Mounting rotors; casings and frames; carcase structures.-Concentric members forming the rotor or stator structure of a dynamo - electric machine are spaced radially apart by pairs of axially disposed plates at an angle to one another forming a starshaped arrangement when viewed axially and joined to the concentric members by fusion of metal. As applied to a rotor, Figs. 3 and 4, the pairs of plates a, b are welded longitudinally to the shaft c and to longitudinal bars d. At intervals, the bars are connected by rings e, the bars and the plates being notched to receive the rings. Pegs a are driven into the shaft close to the ends and pegs h into the bars d to locate the edges of the plates, spot-welding being employed during the erection. In the case of long rotors, intermediate pegs may be employed. On completion, all the joints are welded and the bars d are turned to receive the laminations. The laminations are keyed to the bars and it is only necessary to make keyways j in one pair of diametrically opposite bars. The plates connected to the key-bars only need be welded to the shaft along their whole length; the remainder may be welded at intervals as at k. Apertures m in the plates allow cooling air to traverse the rotor laminations. Fig. 2 shows the invention applied to a stator. If the radial distance between the laminated core and the frame is small, ordinary L-iron may be used instead of the plates a, b. A single key bar d may be employed. Angle members n may be used as external stiffeners and these may be fitted with lifting rings p.

Title: Improvements in or relating to the treatment of starch
IPC: C08B31/08
Filed: 1955-09-28
Abstract: In subjecting starch to chemical or physical treatments, the starch is treated in a fluidized condition, e.g. the starch is fed into a chamber having a porous base through which gas is driven into the chamber.  To render the starch more freely flowing, it may be dried to a moisture content less than normal or it may be mixed with a small proportion of a substance such as silica gel. Examples are concerned with (i) acidifying and drying by treatment under reduced pressure with air and hydrogen chloride gas, followed by treatment at increasing temperatures up to 110 DEG  C.; (ii) dextrinizing by such acid air treatment, followed by roasting at 180 DEG  C.; (iii) neutralizing such dextrinized starch with an ammonia-air mixture and then moistening the product with humid air; (iv) etherification by treatment with an ethylene oxide-air mixture.  Excessive dust formation in the treated product may be avoided by incorporation of a small proportion of a suitable liquid or solid hydrocarbon, e.g., paraffin wax.
