Patent GB-1604204-A (GB)
Title: Switchable magnetic device and method of manufacturing same
IPC: H01F1/03
Filed: 1978-05-03
Abstract: The ferromagnetic changeover device consists of a wire section (10) in which a jacket part (12) and a core part (11) can be magnetised differently. The wire consists of an alloy of cobalt, vanadium and iron. The jacket part and the core part thus have either a matching state, with the same magnetisation direction of the core part and of the jacket part, or a reverse state, with a different magnetisation direction of the core part and of the jacket part. The coercive force of the core part (11) is sufficiently large for the magnetisation of the jacket part in the matching state not to be able to change the core part over into the reverse state. It is thus possible to change over from one state to the other only by means of an external magnetic field. This results in pulses of more than 1.5 V and with a width of 20  mu s being induced in the case of an external magnetic field having a positive half-cycle with a peak value of 11940 A/m and a negative half-cycle with a peak value of 1592 A/m in a coil having 925 turns on a wire section 10 with a length of 3 cm. The changeover device can be used for determining proximity, time measurement and coding. <IMAGE>

Title: Improvements in or relating to the removal of articles from stacks thereof in the manufacture of shoes or shoe parts
IPC: B29D99/00
Filed: 1922-06-26
Abstract: 204,377. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). June 26, 1922. Picking-up tools.-In apparatus for use in the manufacture of shoe parts, a device is employed for picking up disc members, such as the washers or shank pieces of rubber soles or heels, singly from stacks of such members by taking hold of the top member by an external contour and removing it in a direction relative to the stack which renders it unnecessary to constrain the other members in the stack. As applied to the removal of perforated, slightly dished washers, from a stack 21, Fig. 4, threaded on a rod 29 to the moulds 20 in which rubber heels are made, the picking-up device consists of a tubular member 32 with a flared end 39 which, on being pressed on the top of the stack 21, grasps the top washer by friction and carries it away during its upward movement. The member 32 slides in a bar 12 and guide 35 under the action of a spring 41 which normally holds the collar 43 against the top of the bar. An ejector 33 is carried by a top bar 11 and is normally held retracted by a spring 45. The picking-up devices and stacks are, arranged in groups corresponding to the grouping of the washer positioning pins 26, Fig. 1, in the moulds 20 and guide rods 16, 17 are provided so as to facilitate placing the picking-up device over the stack and over the moulds. A device for transferring rectangular shank pieces 54, Fig. 6, from a stack contained in a magazine with slotted sides 57, 58, comprises a pair of levers 60, with bevelled ends 66 and rectangular seatings 68, pivoted on a bolt 74 slidable in slots 76 in the opposite walls of the bifurcated end of a carrier 78, the lower end of which is formed as a foot 80 which acts as an ejector. The upper ends of the levers are rounded and are acted on by a. flanged sleeve 84 and a spring 86 having an abutment on a collar 88 secured to the carrier 78. The carrier may have a handle at its upper end.

Abstract: 1,191,802. Jacks. TANGYES Ltd. 30 April, 1969 [11 April, 1968], No. 17708/68. Heading B8J. A lifting jack comprises a pair of arms 10, 11 pivotally connected by a pin 12, respectively with ground engaging wheels 41, 52, the former on a shaft 40 and the latter on an axle 51 carried by a pair of downwardly divergent arms 15 forming the arm 11. A load engaging pad 20 is dished and is pivoted at one end to the arms 15 through lugs 21 and pin 22. The other end of the pad 20 runs on a roller 31 on a pin 32 attached to the arm 10. A screw threaded member 42 slides through an opening in the shaft 40 and has an eye 43 secured to it by a pin 45. The inner end of the eye 43 bears against a thrust bearing 46 and the member 42 is threaded through a nut 58 held against rotation relative to a bracket 56 against which it bears. Limbs 54 of a tie frame are riveted to the bracket 56 at one end and have holes at the other end through which the axle 51 passes. A second nut 60 is a safety feature supporting the load if the nut 58 strips. The jack is raised by rotating the member 42, using a handle assembly, Fig. 5 (not shown), having a universal joint, so as to draw the wheels 41, 52 relatively together, thus raising the pad 20 by a scissors action. The screw-threaded member 42 may be rotated by an electric, hydraulic or pneumatic motor. Alternatively the member 42 and the nuts 58, 60 may be replaced by an hydraulic ram. In the lowered, inoperative position, Fig. 1, the jack is of considerable length. It may be folded by lifting the pivotally connected ends of the arms 10, 11 so that they lie side-by-side with the pairs of wheels 41, 52 in contact. The frame 55 may be replaced by a flexible assembly incorporating chains or cables.

The spacing of the abutments is slightly less than that of the pushers and the sprocket 14 is driven from the sprocket 10 through gearing such that the ratio of the speeds of the sprockets 10 and 14 equals the ratio of the distances between successive pairs of abutments and pushers, so that the distance between the pushers and abutments engaging the edges of the carton gradually decreases and the carton is set up to rectangular form. To ensure engagement with the abutments, the leading portion of each carton is pushed away from the chains 9, 91 by a rotary deflecting arm 17 driven in synchronism with the sprocket 10. The opening of the cartons is assisted by rotary members 25 also driven in synchronism with the sprocket 10.

Abstract: 1313421 Amylose HAYASHIBARA CO 15 April 1970 [15 April 1969] 18042/70 Heading C3U In a process for producing an amylose mixture containing over 50% by weight of natural amylose by hydrolysing a starch with α-1,6- glucosidase, a suspension of starch containing over 50% by weight amylose is gelatinized, the gelatinized suspension is rapidly cooled to a temperature in the range of from 40‹ to 60‹ C. and there is added an α-1,6-glucosidase to reduce the viscosity of the gelatinized suspension and to prevent retrogradation of amylose during subsequent hydrolysis of the starch with α-1,6- glucosidase. Two different α-1,6-glucosidases, or a mixture thereof, may be employed. Thus, a heat-resistant α-1,6-glucosidase may be added at 50-60‹ C. to lower the viscosity of the starch and then a second α-1,6-glucosidase is subsequently added and the reaction continued at 40-50‹ C. The starch may be gelatinized by heating the suspension at 70-130‹ C. out of contact with air until it is in the form of a paste. The paste and enzyme are fed continuously into a holding tank in which they are mixed with a greater quantity of reaction mixture which is at a more advanced stage of decomposition. The amylose solution obtained may be dried to yield a porous crystalline powder.

The electrodes are parallel to the plane of Fig. 2, so that the rod vibrates longitudinally in a direction normal to the electric field. Such crystals are able to stand stresses up to 15 volts without fracture, and are freed from coupling oscillations and harmonic oscillations by having their width less than one third of their length. For protection against the effects of temperature and moisture, the rods may be bedded in non-hygroscopic substances such as copal.

Vacuum tubes; R÷ntgen-ray tubes.-Sheets permeable to cathode and R÷ntgen rays are made by spraying beryllium or a beryllium alloy on to gold or platinum foil and pressing the foil to the required thickness and density between plates ot iron, nickel or like metals of high melting point. The gold or platinum foil is preferably amalgamated with mercury before spraying the beryllium, the mercury being subsequently distilled off by heating in a vacuum. The beryllium or beryllium alloy coating is applied to the gold or platinum foil preferably to a thickness of from 0.01 to 0.03 mm. and in an example gold foil of 0.001 mm. thickness is coated with beryllium to give a uniform layer of 0.02 to 0.03 mm. thickness and the sheet is then subjected to a pressure of from 500 to 2000 kg. per sq. cm. between two polished steel or nickel plates for from 10 to 20 minutes.
