Title: Improvements in apparatus for packing slivers into cans
IPC: B65H54/84
Filed: 1946-10-14
Abstract: 618,294. Packing arrangements for sliver cans. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Oct. 14, 1946, Nos. 30577/46 and 19386/47. [Class_ 120(iii)] [Also in Group XVII] A vertically reciprocating packer for compressing sliver in a can has a packer rod which slides in a rising and falling crosshead and is acted upon in the crosshead by a frictional gripping device, the grip of which can be varied by adjusting the pressure of a member acting upon it, so that the pressure required to cause the rod to rise relatively to the crosshead, due to the resistance to compression of the accumulating sliver, may be varied. Sliver is fed from a drawing frame into a can 10, Fig. 1, rotated on a base 11, and a packer 14 on the lower end of a rod 15 is raised and lowered on to the sliver at regular intervals by a rod 18, connected to the rod 15 by a crosshead 16. An L-shaped lever 20 is pivoted at 21 between lugs 19 on the crosshead 16. One end of the arm 20 has a screw 23 threaded through it, the screw 23 exerting an adjustable pressure on a spring 24 which tends to turn the lever 20 so as to press a roller 22 against the rod 15. The pivot of the roller 22 is placed a little above the pivot 21, so that the roller bears with a wedging action against the rod 15. As the sliver accumulates in the can 10, the upward pressure against the packer increases until it becomes great enough to overcome the frictional grip set up in the crosshead by the roller 22. In a modification, the lever 20 is formed with a V-shaped cam, instead of having a roller 22, the cam entering into a correspondingly-shaped groove in the rod 15. According to the first Provisional Specification, a spring may be pressed against the rod 15 or a toggle mechanism may be employed. In a further modification, Fig. 4, a movable bush 30 is located between the rod 15 and the bore of the crosshead 16, the latter being conically formed at its upper end 35. Several seg- . ments 36 are placed in the bottom of the conical portion and are pressed downwardly, so as to wedge against the rod 15, by a spring 37, the pressure of which may be adjusted by a screwed cap 39. To release the rod 15, the bush 30 may be raised by a handle 34.

Title: Improvements in or relating to the production of sugar from starchy materials
IPC: C13K7/00
Filed: 1924-12-22
Abstract: 226,812. Fleischmann Co., (Assignees of Gore, H. C.). Dec. 20, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Maltose is produced by liquefying and saccharifying starch in suspension by means of diastase, the liquid being very slightly acid, small amounts oi toluene being ,added from time to time when necessary as a preservative. The starch, which may be in the form of ground and preferably degerminated corn, rice, hominy, &c., is freed from nitrogenous or other soluble impurities, either by washing with water or by treatment with potassium permanganate and sulphur dioxide. The diastase may be employed in the form of malt, preferably pale distillers' malt. In the process described, in order to liquefy the starch the malt is added to the suspension to the amount of 1-2 per cent, and the acidity adjusted by suitable reagents to a PH range of approximately 5 to 6. The liquid is heated to 68‹ C. and gradually raised to 80‹ C., the process occupying from 2 to 4 hours; it is then boiled and cooled to 65‹, ¢ per cent of malt added, and the whole allowed to stand for an hour. Saccharification is then effected by adding 5 per cent of malt and allowing the whole to stand for from five to seven days at a temperature of 40-50‹ C. Small amounts of toluene are added from time to time at any stage when necessary, to act as an antiseptic. The liquid is then filtered, decolourized, and concentrated. Maltose in the form of a fondant is produced by seeding the concentrated liquor wih maltose crystals. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of a dry sugar by dividing the fondant into small pieces and subjecting it to a curing process, for example by heating to 50‹ C., and then grinding. This subject-matter does not appear in the Specification as accepted.

Abstract: 484,457. Actuation of switches. SIEMENS - SCHUCEERTWERKE AKT.- GES. Nov. 11, 1937. No. 31056. Convention date, Nov. 19, 1936. [Class 38 (v)] In a protective device for oil-filled electric apparatus one or more switches controlling signalling or control circuits is or are operated by flow of oil in either direction through a chamber 2. The chamber 2 may be connected, for example, between the tank of the electric apparatus and an oil-expansion chamber. In this case, a short circuit and the consequential liberation of gas would cause a flow of oil away from the tank, while an oil leak would cause a, flow of oil towards the tank. In the form shown in the Figure, a float 1, pivoted at 7, carries a baffle 6. Whichever way the oil flows the spindle 7 of the switch will rotate in the same direction to operate the switch, the float 1 moving away from a stop 9. An additional float 8 may be provided to indicate slow liberation of gas or slow losses of oil. In a modification, Fig. 2 (not shown), a pivoted baffle is used in place of the float.
