Title: Improvements in or relating to malting processes
Inventor: STOWELL KEITH CHRISTOPHER
IPC: C12C1/047
Filed: 1961-06-23
Abstract: A process for the malting of cereal grain comprises the step of subjecting the grain to heat at least to arrest the growth of the grain embryo without damage to the grain and also treating the grain with a gibberellic acid product to effect modification of the grain. The expression "gibberellic acid product" includes gibberellic acid itself and functional derivatives of gibberellic acid having known plant growth promoting properties such as the sodium, potassium, calcium and ammonium salts, and mono-, di-, or tri-esters.  The heating step may be performed by steeping the grain in hot water at between 85  DEG F. and 160  DEG F. for from 2-6 hours.  The gibberellic acid product, in a proportion of between 0.05 and 5 parts per million in respect to the dry weight of the grain, may be sprayed on the grain during or after the heating step or included in the last steeping liquor.  The grain may be additionally treated with sodium or potassium bromate in the following proportions in respect of the dry weight of the grain: between 50 and 1000 parts per million when included in steeping liquor, and between 10 and 200 parts per million in a spraying solution.  Examples are directed to (i) steeping barley for 6 hours in steeping liquor at stated temperatures within the range from 85-160  DEG F. followed by immersion for 24 hours in a solution at 55  DEG F. containing 2 parts per million gibberellic acid in respect to the dry weight of the barley, and (ii) steeping barley for 24 hours in steeping liquor at 55  DEG F. followed by immersion for 6 hours in a solution at 105  DEG F. containing 2 parts per million of gibberellic acid; in certain experiments between 100 and 1000 parts per million of potassium bromate were included.

Patent GB-929666-A (GB)
Title: Improvements in pattern means for circular knitting machines
IPC: D04B15/74
Filed: 1960-06-30
Abstract: 929,666. Knitting. TEXTILE MACHINE WORKS. June 30, 1960 [July 6, 1959], No. 22991/60. Class 74 (2). Single needle increasing in the formation of true Argyle patterns on socks on a four-feeder machine as described in Specification 790,141 is achieved during reciprocatory knitting by providing for the. needles to be operated at each feeder, a central group of jacks having a group of butts 51 flanked on either side by a group of jacks each having a group of butts 56, 57 ranging over levels corresponding to the levels covered by the butts of the central group of jacks. In addition the central group of jacks has butts 55 all at one level beneath the other jacks of the group and the group of jacks on either side of the central group has butts 62 at a still lower level. The jacks are normally rendered operative by failure of selectors to press the butts. At the commencement of the formation of a diamond at one. feed the selector for the butts 62 is operated to render the corresponding jacks inoperative whilst the selector for the butts 55 on the central group of jacks is rendered inoperative to leave the jacks of this group free for selection by the associated selectors in turn failing to operate on the butts of the group 51. Accordingly at the commencement of the diamond the central two needles corresponding to the central two jacks of the groups 51 are operated and take and knit yarn at the feed. Subsequently in each direction of reciprocation selectors are rendered inoperative so that additional jacks are operated by their butts 52 until all of the jacks of the central group 51 and the corresponding needles are operative. During this period, although the selectors corresponding to the butts 52 are gradually rendered inoperative to permit operation of the associated jacks, the jacks with the group of butts 56, 57 on the same level as the butts of the central group are retained out of operation by the selector acting on the butts 62. To continue the needle selection beyond the central group of jacks, the same selectors as were used for selecting the jacks of the central group are used and to enable such selection to be made the selector operating on the butts 62 is now rendered inoperative whilst another selector is rendered operative to operate the butts 55 on the central group of jacks to render then inactive. Consequently the selectors when operated will now only affect the jacks of the groups 56, 57 which they do in turn to complete the diamond. Since the central group of jacks is inoperative, to ensure operation of the needles, butts 66 are provided on additional jacks 49 provided at a higher level and these butts are engaged by pivoted cams on each stroke of reciprocatory knitting to ensure that the associated needles are actuated for knitting.

Title: Improvements in or relating to means for starting and stopping internal combustion engines
IPC: F01L13/00
Filed: 1939-08-10
Abstract: 533,443. Starting; turning-gear; stopping. ONIONS, R., AUCKLAND, J. H., and RUSTON & HORNSBY, Ltd. Aug. 10, 1939, No. 23067. [Class 7 (v)] A starting valve 1, for supplying compressed air to the working or combustion chambers or the cylinders of an engine, or compressed air or other fluid to a starting motor, is normally held or locked in its closed position against the action of a weight or spring, which opens the valve on the release of the locking means ; the compressed air &c. is then delivered for starting until the engine has attained a pre-determined speed or has rotated a pre-determined number of revolutions, or for a pre-determined time, whereupon the valve is closed tightly on its seal and the locking means is automatically re-engaged. As shown, a lever 8 for opening the valve carries a weight 12, which may be adjustable, and is pivoted at 9 on a bracket 10 on the valve casing 3. The lever comprises spaced arms provided with pins for engagement with the upper face of a sleeve 7, secured on the valve spindle 2 by a pin 21, when the valve is being opened ; the sleeve 7 surrounds a fixed guide 11 for the valve spindle and the pin 21 is guided in slots 20 in a sleeve 16 loosely mounted around the sleeve 7. On the closing of the valve, the pins 15 bear against a floating collar 24, between which and an adjustable collar 23 is interposed a spring 22 adapted to hold the valve firmly closed. A ratchet 25 on the lever 8 is normally engaged by a pawl 26 pivoted at 27 on the bracket 13, to which it is connected by a spring 28, and the front face of the pawl lies against the flat of a D-shaped cam on a spindle 30 carrying an arm 31 resting on a stop 32. Actuation of the arm 31 manually or by an electromagnet 33 or other means serves to disengage the pawl 26, allowing the weighted arm 8 to open the valve for starting, the weight 12 falling on a stop block 14 of the bracket 13. During the opening movement, a partial turn is given to the valve by a link 37 having a pin- and-slot connection with the sleeve 16. At the same time, a rod 55, connected to the lever 8 through a spring 45, swings a lever 47 to bring its roller 49 into engagement with the spirallygrooved cam 46. When the engine shaft has made a pre-determined number of revolutions, a tappet 56 on the lever 47 opens a valve to admit compressed air to a cylinder 34 actuating a plunger 35 whereby the lever 8 is lifted and the valve 1 closed on its seal. Compressed air. is also admitted to a cylinder 61 actuating a plunger 65 whereby a fuel-pump control lever 62 is swung into operative position. The lever 62 is normally held by a spring 66 against a stop 67 and when swung to operative position is retained by a, detent lever 71 actuated by a spring 73. Release of the detent lever is effected manually or by a solenoid 74 when it is desired to stop the engine. The stopping means may alternatively be applied to a gas control valve or the ignition system.
