Patent GB-609821-A (GB)
Title: Improvements in or relating to aqueous hydrolysis reactions of hydrolysable fatty materials
IPC: C11C1/04
Filed: 1945-08-09
Abstract: Fatty material is hydrolysed with water to give fatty acids and glycerine by a process in which a current of the fatty material is acted upon by a counter-current of heated water while subjected to elevated temperature and sufficient pressure to maintain water in the liquid phase, the water being heated by heat exchange with the fatty acids leaving the process and also by direct steam injection.  In Fig. 1, molten fat enters autoclave 1 through line 5 while heated water enters the autoclave through distributer 2. Fatty acids leave the autoclave through tee 10 and glycerine water through line 3. Water is supplied by distributer 33 to heat exchange vessel 32, fatty acids entering vessel 32 through line 28 and leaving through line 34. The heated water leaving vessel 32 is further heated by means of steam injector 36 before passing to autoclave 1.  Since vertical line 31 has water and fatty acids passing in opposite directions along it, a certain amount of fatty acid is always returned to autoclave 1 through distributer 2.  In the alternative arrangement shown in Fig. 2, the molten fat enters heater 49 through line 48 and passes to reservoir 51.  The molten fat is forced from reservoir 51 through line 53 to the autoclave by means of compressed nitrogen or other inert gas entering through line 55.  In the alternative arrangement shown in Fig. 3, molten fat is forced by pump 60 and steam injector 36 <PICT:0609821/III/1> <PICT:0609821/III/2> <PICT:0609821/III/3> through distributer 63 into reservoir 64 and from there through line 67 to the autoclave 1.  Any steam which condenses in reservoir 64 collects as water at the bottom together with any glycerine formed through hydrolysis occurring in the reservoir, and this glycerine water is passed to autoclave 1 through line 70.

Title: Improvements in Heat Engines.
Inventor: FREDERICK ALFRED EDWARD JENKIN
IPC: F02B25/00
Filed: 1918-12-10
Abstract: 121,481. Jenkins, F. A. E. Dec. 5, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Valve-gear. - In an engine which normally ignites its charges by the heat of compression and, when starting, uses a low compression and a light fuel, air charges are compressed ia crank chambers 55 and transferred to the combustion chambers through a valve 61 in each piston. Each crank chamber is provided with an inlet valve 67 and with an equalizing piston 64 which maintains a substantially constant delivery pressure during the transfer of the charges to the combustion spaces. The pistons 64 may be actuated mechanically; or they may be automatic, being returned by springs. The fuel pumps 70, Fig. 36, are connected to supply pipes (not shown) for light and heavy fuel, and their common plunger is actuated by a rocking arm 89 pivoted at 132 and engaged by cam surfaces on an adjustably rotating drum 73. To vary their strokes, the pumps are adjusted on a base-plate x by a screw 74 and a hand-lever 69. The exhaust valves 68 in the heads of the two cylinders shown in Fig. 4 are actuated by concentric rocking shafts 120, 121 having arms 123 which engage spherical ends on the valve stems. Mounted upon an eccentric 111, Fig. 40, is a member 86 having a pair of cams 115 for starting and a second pair 117 for normal running, a set of cams 115, 117 serving to actuate each exhaust valve. The cams of each set engage an arm 122 pivoted at 152 and mounted in the path of a projection 151 carried by an arm 150<A> connected to a valve rod 118. The arms 122 are each connectedl by an arm 144 and a rocking arm 126 carrying a toothed segment 131 to a rod 65 of one of the equalizing pistons in the crank chambers. The segments each engage a pinion mounted upon an eccentric carrying a pin 127 connected to one of the rods 65. At starting, the exhaust valves 68 open towards the ends of the working strokes and close when the pistons have completed ¥ of their compression strokes, the fuel being injected at approximately ¢ stroke, When the hand-lever 57, which is connected to the exhaust valve cams 86 and to the cam 73 for actuating the fuel pumps, is adjusted for normal working, the exhaust valves close early in the compression strokes and the fuel is injected at the end of the stroke. Heavy fuel is used for normal working.

Title: Improvements relating to electrical counting
Inventor: ROWLEY GEOFFREY CHARLES
IPC: H03K21/00
Filed: 1958-06-30
Abstract: 864,462. Reversible counters. ROE & CO. Ltd., A. V. June 16, 1959 [June 30, 1958], No. 20835/58. Class 106 (1). The modulus of a reversible counter can be altered by changing connections to a gating device which detects when forward or reverse transfer should be effected. The invention is applied to a reversible binary counter in which forward and reverse pulses are fed to a common inlet and separately to transfer gates. In a forward count when the first flip-flop changes from 1 to 0 the associated transfer gate opens to pulse the succeeding flip-flop. In a reverse count this occurrence takes place when the first flip-flop changes from 0 to 1. The outputs of the flip-flops are connected to an " end count detector a. In a forward count when the upper limit is detected gate e opens to effect carry and to reset the flip-flops to the lower limit. Corresponding changes are effected in a reverse count by the opening of gate d. Fig. 2 shows the connections for a modulus of 5 with lower and upper limits of 2 and 6, the " end count detector " and gates d, e being combined to form 4 gates f, g.

Title: Improvements in wire tightening and twisting mechanism
IPC: B65B13/28
Filed: 1935-07-23
Abstract: 442,652. Twisting wires together. COX, H. W., 21, Howard Street, North Melbourne, Australia. July 23, 1935, No. 20849. [Class 83 (iv)] [See also Group I] In strapping boxes the wire is held in a pivoted gripping assembly 33, described in Specification 420,098, and passed through a twisting pinion 27, around the box, again through the pinion, and finally round a tightening drum 23. On manual or power operation of a shaft 10, the wire is first tightened by rotation of the drum 23 and when a certain tension is reached the drive is transferred automatically to the twisting and cutting mechanism. The shaft 10 is connected with the drum 23 and the pinion 27 through epicyclic gearing 12 ... 15 and drives one or the other according as the pinion 15, which is loose on the shaft, is locked or free. The pinion 15 is integral with a pinion 16 which drives the twisting pinion 27 through an intermediate shaft 26. In the position shown, the pinion 16 is locked by a wedge-shaped pin 18, so that rotation of the shaft 10 drives the planetcarrier 19, which in turn drives the drum 23 through a one-way clutch 21 and gearing 22 to tighten the wire. When the tension overcomes a spring (not shown), the gripping assembly 33 swings about its pivot and withdraws the pin 18 from the pinion 16 by means of a link 32, the gripper being retained in that position by a spring catch. Continued rotation of the shaft 10 now drives the pinion 16, shaft 26, and twisting pinion 27 ; at an early stage in the twisting, a cam on the shaft 26 operates a cutter 30 to sever the wire between the gripping assembly 33 and the twisted portion. Further rotation of the shaft 26 continues the twisting and operates a cutter 31 to nick the wire between the twisted portion and the drum 23. Finally, a trip member on the shaft 26 releases the spring catch which holds the gripper 33, and the pin 18 is returned by springs to lock the pinion 16. The drive is thus transferred back to the drum 23 and increased tension severs the wire where nicked.
