Title: Stable syrup of high dextrine content and method of manufacturing same
Inventor: CLELAND JAMES EDWIN
IPC: C13K1/00
Filed: 1951-03-05
Abstract: A clear and stable syrup is produced by a process which includes the steps of hydrolysing a starch with an acid to a relatively low dextrose equivalent of 16-24, then hydrolysing by means of a diastatic enzyme the partially hydrolysed syrup so formed to a relatively higher dextrose equivalent of 26-40 and then concentrating the syrup to about 38 DEG  to 43 DEG  B<\>e.  The invention also comprises as a new product a sterile, stable low viscosity liquid syrup having a ratio of fermentable extract to dextrose equivalent of from 0.8 to 0.96 and a dextrose equivalent of 26-40.  In an example starch e.g. corn starch is acidified and hydrolysed with heat and pressure using sulphuric or hydrochloric acid but the hydrolysis is stopped when the dextrose equivalent is 16-23, the hydrolysate is then neutralised to a pH of 4.6 to 5.4 and then maintained at 100-135 DEG  F. in a tank.  An enzyme preparation pre-dominating in diastatic activity e.g. the products known as Clarase or Rhozymes is then added and hydrolysis continued until the dextrose equivalent is from 26 to 38.  Part of the protein coagulum of the acid hydrolysed syrup is converted by the enzyme to amino acids.  The remaining insoluble protein and oils are removed in a skimming device and the syrup then filtered and refined by bone char or activated carbon.  The syrup is then evaporated to a concentration of 38-43 DEG  B<\>e.  The syrup may then be further refined by subjecting it to a high temperature heat treatment and then to filtration at high concentration and high temperature.  Thus the syrup may be heated to 180 DEG  to 240 DEG  F. and filtered.  The syrup is preferably first concentrated to 40 DEG -41 DEG  B<\>e, heated to 220 DEG  F., cooled to 180-190 DEG  F. and then filtered in this temperature range.  The resulting amber-coloured syrup may then be further treated by heating to 220 DEG -250 DEG  F. in a jacketed pressure vessel and then allowed to cool rapidly to bottling temperature to yield a sterile product.  It is stated that the syrup products of the invention are of low viscosity and ordinarily have a ratio of fermentable extract to dextrose equivalent of 0.8 to 0.96.  Other starches e.g. from potatoes or other common plants may be employed.

Abstract: 659,500. Railway signalling apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 3, 1949, No. 5865. Convention date, March 5, 1948. [Class 105] When a train enters the section in rear of an occupied section a device comes into operation to give a visual indication to the driver of the distance he has entered into such rear section, but the indication ceases as soon as the ahead train moving forward has left a clear intervening section; the signalling is effected electrically and continuously from the rails, e.g. by inductive action. The arrangement shown includes lamp signals K, V, S for the clear, caution, and stop signals transmitted inductively from the rails. When the caution signal V is received a magnet m releases its armature whereby a worm s driven from a bogie wheel d and fitted with a striped drum i to show its rotation is pulled into engagement with a wheel h carrying a pointer v. When the pointer reaches the far end of the scale it closes a contact k to apply the brakes. If the ahead train moving forward leaves an intervening free section the magnet m is energized and pulls up its armature to disengage the worm s ; a spring g sets the pointer v back to its starting point.

[Class 36] A tubular body, formed of flexible metal or of firm but flexible insulating material, for use in a cable, e.g. as a conductor, screen, armouring, pressure protective covering, or insulating sleeve, consists of a band bent about a longitudinal axis into tubular form or a plurality of arcuate bands assembled into tubular form, the edges of the band or assembled bands either abutting and, if desired, being welded together, or overlapping circumferentially without being folded together. The body is rendered flexible by widely spaced transverse grooves or group of grooves, or by a continuous groove or grooves having a long pitch. The band or bands may be arranged parallel to the cable axis or may extend helically with a long lay. Fig. 1 shows a coaxial air-space insulated cable having an outer conductor 11 formed by two arcuate bands held together by a binding 15 and formed with transverse grooves' 12. The inner conductor 10 is supported by insulators 13 each having a groove 14 which is engaged by the internal ridge formed by the grooves 12. In a modified construction the bands are formed with pairs of grooves between which the insulators, in the form of discs, are held. The insulators may be of such form, e.g. as shown in Fig. 12, that they may be permanently attached to the outer conductor bands 54. The inner conductor 57 may also be permanently attached to the insulators 56. To prevent the edges of the bands from sliding inwardly over one another the grooves of the bands may be staggered, or the edges of the bands may be flanged, corrugated, or provided with indentations. To prevent contact between the inner and outer conductors thin insulating sheets or shells may be arranged in the ungrooved portions of the outer conductor bands. The grooves may be provided with longitudinal slots to increase the flexibility of the band. Fig. 26 shows grooved and slitted insulating tubes 113 wound about a conductor 112 to provide an air-space insulation. In a modified construction the conductor is supported within an insulating tube by slitted grooves in the tube. In the construction shown in Fig. 36, the tubular body is formed of bands 173, 174 having outwardly directed grooves 175, 176 respectively. The tubular body may have both inwardly and outwardly directed grooves, Fig. 49, showing a band from which such a body may be formed.

Abstract: 1,172,265. Grinding. T. HATUKANO. 13 Feb., 1967 [12 Feb., 1966], No. 6739/67. Heading B3D. A method of processing materials, such as drilling gems, by ultrasonic oscillations comprises repeating, in turn, the steps of bringing an ultrasonically oscillated needle 5 into contact with a material on a table 3, supplying an abrasive agent between the needle and material to drill, grind or finish the latter while moving the needle slightly downwardly, moving the needle upwardly a predetermined distance, grinding the tip of the needle by rotating it an moving it slightly downwardly while bringing a horizontally movable grinder 9 into contact with the tip of the needle, separating the grinder from the tip of the needle and simultaneously moving the needle downwardly to permit its tip to contact another workpiece, and applying ultrasonic oscillations to the needle. In apparatus for carrying out the method, a bed 2 is horizontally movable by a motor M 4  between right and left positions and carries a rotatable table 3 for supporting the material to be worked and a grinding device 4. The device consists of a plate 13 which is adjustable about a pivot 12 and supports a plate 14 which in turn carries the transmission for the grinding wheel and is adjustable in two directions at right angles. The needle 5 is mounted on an ultrasonic head 7 vertically adjustable on an upright 1 of the machine to position the needle at P 1  for working on the material and at P 2  for being ground. The machine is operated by a series of press buttons and limit switches and in order to effect grinding of the needle, the head 7 and needle are moved to their upper position P 2  and the bed 2 moved a distance α to the left to engage the grinding wheel with the needle, both the needle and grinding wheel being rotated and the grinding wheel also being axially reciprocated as the needle is slightly lowered. At the end of the grinding operation, the needle is lowered at the same time as the bed 2 is moved to the right to position the table 3 below the needle. The needle is then further lowered relative to the head 7 to position P 1  to contact the workpiece, the ultrasonic oscillator is actuated, an abrasive agent is pumped from a device 10 to the working area, and the table 3 is rotated. After a working period determined by a timer, the working operation is stopped. During grinding of the needle by the grinding wheel 9, the table 3 is located below a gauge 8 by means of which the depth of grinding can be measured.

Abstract: 906,888. Discharge lamp circuits. GENERAL ELECTRIC CO. Ltd. Feb. 22, 1961 [Feb. 25, 1960], No. 6741/60. Addition to 847,391. Class 38 (4). In an arrangement as disclosed in the parent Specification modified for use on a supply of not less than 300 c.p.s., the ballast is a capacitor 3, and a branch circuit comprising a rectifier 6 and a resistor 7 is connected directly across the lamp. Initially, the rectifier 6 charges the capacitor 3 to approximately peak A.C. voltage which is additional to one half wave of the supply voltage, and which is sufficient to strike the lamp. After striking, the D.C. voltage across the lamp falls and D.C. current circulating through the lamp is restricted by a resistor 7. A starting strip 12 may be connected to one terminal 2 of the supply through a resistor 13. If the lamp has heatable electrodes, a heating transformer 8-10 may be provided. The lamp striking voltage may be increased by connecting the resistor 7 to a point 14. Another arrangement described in the Specification (Fig. 2, not shown), has additional auto-transformer windings for increasing the lamp and D.C. voltages respectively.
