Patent GB-633003-A (GB)
Title: Starch conversion process
IPC: C13K1/06
Filed: 1947-03-31
Abstract: The Specification as open to inspection under Sect. 91 describes a process for the production of starch conversion products by impregnating the starch with a starch degrading chemical, preferably an acid, so as to form a non-fluid mass, and heating said mass, while preventing any substantial loss of water, at a temperature and for a time to yield the desired degradation product.  Loss of water during heating is preferably prevented by maintaining the mass under superatmospheric pressure, and steam may be forced into contact with the mass for at least a part of the heating period.  The process may be made continuous by forcing the impregnated mass continuously through a reaction zone where the mass may be maintained under superatmospheric pressure and steam forced into contact with it.  In an example 300 kg. of potato starch having a water content of about 20 per cent are treated with 450 cc. of 32 per cent hydrochloric acid dissolved in 6 litres of water and the resulting mass held in a stirring vat provided with a double jacket at an outside temperature of 55 deg. C. for about 2-3 hours, until a sample shows cream-like consistency when boiled in 8 times as much water.  The product may be used as a food starch or for industrial purposes, depending on the degree of purity of the original starch.  This subject-matter does not appear in the Specification as accepted.ALSO:Glucose-containing products are obtained from starch by heating and stirring a commercially dry to moist mass of acidulated starch in an enclosed reaction space until a desired glucose-containing product has been obtained, a part of the heating following a preliminary period of hydrolysis being effected by injecting live steam, preferably superheated, into the mass, and while heating the mass maintaining it under a counterpressure, preferably from a gas such as air or nitrogen forced into the reaction space from outside the reaction chamber, sufficient to prevent any substantial loss of water from the reaction material.  The mass may be heated from surfaces of the reaction container throughout the heating period and by injection of steam only during an intermediate part of this period, the steam preferably being injected at a time when the mass tends to stiffen in the absence of steam.  The conversion may be carried out continuously through an enclosed reaction space while steam is injected continuously into the advancing mass only in a limited part of the length of the space and a gas under pressure may be applied continuously to the mass ahead of the steaming zone so as both to hold the natural water content of the mass and to limit the length of the zone.  The temperature of the reaction should not substantially exceed 130 DEG C and an acidulated mass heated at 130 DEG C for 30 to 60 minutes yields a product having a dextrose content of about 40 per cent.

Title: Improvements in or relating to the feeding of strip material
IPC: B41L5/06
Filed: 1937-03-24
Abstract: 492,678. Memorandum appliances. STANDARD REGISTER CO. March 24, 1937, No. 8730. Convention date, May 28, 1936. [Class 16] [Also in Groups XVI and XX] In strip-feeding arrangements for use in autographic registers or other apparatus and comprising pins co-operating with holes in the strip to impart a substantial feed-movement at each operation, the pins engage the holes loosely during a substantial part of the movement, and closely during the remaining part. Close engagement may occur in both the longitudinal and transverse directions, or in the longitudinal direction only. Loose engagement of the pins compensates for irregularities in the spacing of the holes and facilitates engagement and disengagement, and close engagement positions the strip accurately at predetermined intervals. Preferably, the pins are in close engagement at the end of the movement and serve to hold the strip stationary while it is receiving entries. When superposed strips of paper, with or without interleaved carbon &c. strips are employed, the strips are relatively moved into register during loose engagement of the pins. In the autographic register shown in Fig. 3, a shaft 13 is provided with pin-wheels 12 each having conical pins 14 for loosely engaging holes in a strip 5, and a larger pin 16 which, after one revolution of the shaft, engages a hole and holds the strip stationary on the' writing plate 2. If a shorter feed-movement is required, the shaft is turned through a halfrevolution at each operation, and the pinwheels are provided with diametrically-opposite pins 16. If the pin-wheels have an odd number of pins, a pair of adjacent pins 16 is arranged diametrically-opposite another pin 16. Instead of employing pins of different sizes, the strip 5, Fig. 8, may be provided with large and small holes 6, 6a for co-operation with pins of uniform size.

Title: Improvements relating to electric switchgear having arcing contacts
IPC: H01H33/12
Filed: 1944-05-19
Abstract: 576,398. Arc rupturing in switches. ERSKINE, HEAP, & CO., Ltd., and ALLCOCK, W. May 9, 1944, No. 8798. [Class 38 (v)] In closing a circuit-breaker, circuit is made simultaneously by main and arcing contacts but in opening it is broken finally by arcing contacts only In Figs 3 and 4 one of the pair of main contacts with its operating mechanism is shown on the left and one of the pair of arcing contacts with its operating mechanism is shown on the right. In Fig. 3, a moving contact bar p in withdrawing has allowed a displacing member a to move downwards under action of a spring b, so rotating a lever g carrying a main contact k about a pin h, while a roller follows a cam path f from a recess e to a recess d. When the bar p has cleared an arcing contact m, the lever g of the latter enables its displacer to travel downwards while its roller moves into the upper recess in like manner. The final outward movement of contacts m increases the breaking speed. When the bar p moves upwards to close the breaker, it engages insulating blocks q on each displacer to raise the latter and cause all contacts to close simultaneously. A final movement of bar p gives a cleaning action. Each displacer has a hollowed-out upper face n which provides a dash-pot action with a block o if the breaker is oil-immersed. The main and arcing contacts may alternatively be mounted on the same composite levers, Figs. 6, 7 (not shown). In Fig. 9 the arcing contacts m move at right-angles to the path of movement of the main contacts as a roller j1 rides on a cam path f1, on a lever t, which is carried by the displacer operating the main contacts and is urged clockwise by a spring u. The bottoms of the arcing contacts are level with the top of the first vent of an arc control pot w. In all forms the bar may be rectangular, cylindrical, square or hexagonal. The main contacts may be connected to the arcing contacts through a resistance. When in the closed position, the top portion of the movable bar is clear of the top of the contacts and the bottom of the bar is clear of the arcing contact tips, ensuring engagement only between undamaged surfaces. Specification 576,114 is referred to.
