Title: Improvements in and relating to the manufacture of products derived from maize
IPC: B02B1/00
Filed: 1928-11-01
Abstract: 324,702. Acton, W. Nov. 1, 1928. Starch.-Maize, after being steeped in a weak acid solution in tanks 1 is conveyed by pipes 2<a> to a degerming mill 2 whence it passes to a germ separator 3. The starch cells of the. degermed maize are then ruptured in mills 4 and the resulting starch liquor conducted on to coarse sieves 5, the liquor passing through proceeding to fine sieves 6. The residue on the sieves passes by gutter pipes 14 to a tank 13 while the liquor passing through the fine sieves is mixed with aikalina liquor from a tank to give it a pH value of 6.5 and is led at a temperature of about 40‹ Cent. on to starch separating tables 8. The separated starch is transferred to the tank 9 wherein it is washed with a dilute solution of caustic soda and allowed to settle after which it is washed with fresh water in vats 10, 11, the alkali being neutralized by acid. The washing water from the vats 10, 11 is conducted by a pipe 15 to a sieve 12 wherein the separated germs are washed free from starch : the liquid then passes through a heater 16 to a tank 17. A mixture of alkali liquor from this tank and acid liquor from a tank 18 into which used steeping liquor from the tanks 1 passes, so that the mixture has a pH value of about 5 and is at a temperature of approximately 46‹ Cent., is fed to the maize in the dege.rming mill 2, a further portion of the acid liquor being passed into a storage, tank 13 for the bran &c. separated-off by the sieves 5, 6. The liquid from the starch separating tables 8 is regulated to pH 4 by means of partly used steep water and part is conducted to the bran tank 13 and the remainder used for washing the material from the sieves 5, 6. The contents of the tank 13 are pumped through a filter press 7 the separated matter being dried for maize gluten feed. The liquid from the press is taken to towers 12 for reacidifying for further use in the steeping tanks.

Title: Improvements in or relating to circuits including two oscillators or amplifiers comprising discharge tubes and a load, the oscillator or amplifier from which the load is normally supplied being replaced by the other in the event of a disturbance
IPC: H04J1/16
Filed: 1945-11-24
Abstract: 604,247. Valve generating circuits. PHILIPS LAMPS, Ltd. Nov. 24, 1945, No. 31763. Convention date, July 20, 1940. [Class 40 (vi)] A circuit arrangement comprises an oscillator or amplifier which is replaced by a second oscillator or amplifier in the event of a disturbance, and wherein each oscillator or amplifier is such that a variation of one of the operating voltages or one of the electric constants effects a sudden permanent change in its operating condition. Fig. 4 shows an oscillator 1 and a second oscillator 1<1>, the circuit constants being chosen so that oscillations commence, only if contacts 9 and 9<1> are closed, thereby reducing the negative grid bias, but, once started, oscillations are maintained with these contacts open. Relays 20 and 15, which operate while the oscillators 1 and 1<1> respectively are functioning, control the operation of subsidiary relays 21 and 22, and arrange for contact 16 to connect the load to oscillator 1<1> in the event of the failure of oscillator 1, and for the operation of alarm circuits A. In the event of the failure of both oscillators, alarm B is operated, and contacts 9 and 9<1> close so that at least one oscillator delivers energy to the load on restoration of the supply voltage. An alternative arrangement for each oscillator or amplifier is shown in Fig. 5, where part of the output energy is arranged by means of rectifier 30, to supply a compensating voltage across resistance 10 to reduce the negative grid bias. To avoid the risk of intermittent oscillation in this circuit, a voltage limiter may be connected across resistance 10. In the case of amplifiers dealing with non-constant signals, the circuit shown in Fig. 5 may be modified by arranging for the compensating voltage to be developed from an auxiliary oscillation of constant amplitude and outside the signal frequency range; which is fed to the input of the amplifier through a series connected transformer.

Abstract: 665,827. Tractor-trailer couplings. FERGUSON HOLDINGS. Ltd., H. Nov. 13, 1948 [Dec. 8, 19471. No .32275/47. Class 103(v) In a coupling between a tractor and a trailer, of the non-self balancing type in which part of the weight is taken by the coupling, a hydraulic lift on the tractor is used to lower or raise a coupling element thereon and to engage it with a coupling element on the trailer without the necessity of the driver leaving his seat. On the tractor, the hydraulic lift crank 5 is coupled to the draft links 1 by means of a bar 4 in the usual manner, and the draft links 1 have pivoted at their rear ends, links 29 pivoted at their other ends to an arm 26, near to its hook 27, the arm 26 being in turn pivoted at its forward end to the tractor frame at a point 25 below and just forward of the tractor rear axle. To couple the tractor and trailer, the draft links 1 are lowered by operation of the driver's control lever' 12A until the hook 27 of arm 26 rests almost on the ground. The tractor is then backed until the hook 27 comes below an eye 21 on the trailer which is kept raised from the ground by the stand 22, and raising of the draft links 1 then completes the connection. The draft links 1 are limited in their upward movement by a telescopic compression member pivoted to the tractor frame at 40 having outer and inner elements 35 and 36. A catch 43 secured to the inner element 36 by abutting against part 47 of the outer element 35 takes the unbalanced weight of the trailer and relieves the tractor hydraulic system of stress after the coupling has been made. Figs. 1, 2, 3, 5, 7, 8, 9, 10, 11 and 12 of the drawings of this Specification form the drawings for Specification 665,904, the claims of which are directed particularly towards the provision of means to prevent the lift links from being raised beyond the point at which the hydraulic pressure supply is cut out, so that the power pump may continue to operate some other auxiliary device. Figs. 1, 2, 3 and 4 form the drawings for Specification 665,905, the claims of which are directed particularly towards the provision of the cross-bar 30 which limits the possible veering movement of the tractor.
