Patent GB-1165328-A (GB)
Title: Continuous Fermentation Apparatus and Process
Inventor: PORTNO ANTONY DAVID
IPC: C12M1/02
Filed: 1966-04-15
Abstract: 1,165,328. Centrifugal separators. BREWING PATENTS Ltd. 29 March, 1967 [15 April, 1966], No. 16745/66. Heading B2P. [Also in Division C6] Apparatus for carrying out continuous fermentation comprises an enclosed fermentation vessel 1, Fig. 1, an inlet for fresh liquid 2 and an outlet passage 5 for fermented liquor, arranged on the axis of rotation i.e. within the spindle 6, of a rotor 3. The rotor has a number of passages 4 extending radially and upwardly from its periphery to the outlet passage. The discharging fermented liquor spills over into a collector 8. The removal of gas through space 11 is assisted by a vortex-producing paddle 9. A stirrer 12 may be carried on a downward extension from the spindle 6. Referring to Fig. 3, the rotor 33 and associated passages 34 leading to outlet passage 35 are arranged within a stationary shroud 39 within the fermentation vessel. The fermenting organism e.g. yeast, becomes concentrated in the space 42 by the rejection action of the rotor 33 and may be passed back into the fermentation vessel through a series of apertures 43 in the wall of the shroud. Preferably, however, the yeast is displaced in the form of a cream through a passage 44 into a space 45, from which the whole or a part of the yeast may be discharged or recycled. According to a third embodiment (Fig. 2, not shown), two conical rotors are provided within a generally conical fermentation vessel. Alternatively, a cylindrical rotor may be mounted within a cylindrical fermentation vessel. Examples are directed to the fermentation of brewer's wort to produce beer, employing specified yeasts. Results give the rate of yeast outflow in the fermented liquor for rotor speeds of up to 1200 r.p.m. In general, a minimum yeast outflow is necessary in order to maintain the activity of the yeast in the fermentation vessel. It is demonstrated that for flocculent yeasts there is a critical rotor speed at which the escape of yeast is at a minimum. The apparatus may be employed in the production of penicillin.

Abstract: 594,628. Controlling motor vehicles. STIEGER, H. J. July 3, 1945, No. 16893. [Class 79 (v)] A light goods vehicle having a steerable wheel at one end and a pair of wheels at the other end one or both of which are driven by an internal combustion engine through a centrifugal clutch, is controlled by a lever which can be moved in one direction to speed up the engine and so engage the centrifugal clutch, or in the other direction to apply a brake. The control lever may be connected to the throttle either directly or through a governor. The control 'lever may be locked in the braking position, the lock being releasable by a key which the driver may carry on a bracelet. The truck 10 comprises a front wheel steered by the tiller 23 from the driver's platform 15, and a pair of wheels 12, 13, at least one of which is driven through a centrifugal clutch from an internal combustion engine (not shown) mounted on the platform 15. The control lever 24 is rigid with the transverse tube 25, and forward movement of the. lever rotates the tube 25 and arm 26 to depress rod 27 which actuates the engine throttle either directly or, as shown, through a governor 20, in which case the governor driven from the engine by shaft 43 adjusts the throttle by link 21 to maintain a given engine speed, movements of the lever 30 and rod 32 serving to adjust the datum of the governor and hence the engine speed. Rearward movements of the control lever 24 lifts the arm 26 clear of the rod 27 and so does not affect the throttle, and pin 34 engages lever 35 to apply a brake through rod 36. During forward movements of the control lever 24, the lever 35 rests on pin 37 and so is unaffected. The control lever 24 may be provided with a pawl and ratchet 40, 41 which may be retracted if desired by engaging the hook 38 on the pin 44. The control lever 24 may be duplicated at 124 on the other side of the vehicle, to give independent braking on the two rear wheels. The driver's platform may be at the front of the vehicle instead of the rear, and the control lever may be foot operated instead of manually. Specification 594,630 is referred to.

IPC: H01P5/18
Filed: 1958-05-28
Abstract: 918,419. Impedance networks. GENERAL ELECTRIC CO. Ltd. May 26, 1959 [May 28, 1958], No. 17012/58. Class 40 (8). A transmission line coupling arrangement has n coupling sections between the two transmission lines, wherein the characteristic impedance of each coupling section, if the coupling sections are in series connection with the two transmission lines, or the characteristic admittance thereof, if in shunt connection, is approximately proportional to sin (2r-1) #/2n, where r is the number of the coupling section counted from one end of the arrangement, allowance being made for junction discontinuities. Each coupling section has uniform characteristic impedance along its length and the electrical distance along each of the two transmission lines between the effective junction with each coupling section and the effective junction with each adjacent coupling section and the electrical lengths of the coupling sections are all approximately the same-a quarter wavelenth at the operating frequency. The arrangement is applicable to hollow waveguides or coaxial lines. In the arrangement shown, the dimensions b 1  b 2 , b 3 , b 4 , b 5  of the coupling sections 5, 6, 7, 8, 9 in series connection between the waveguides 1 and 2 are proportional to # sin (2r - 1) -. The division of power between 10 the waveguides 1 and 2 can be altered by multiplying the dimensions b 1  to b 5  by a common factor. A particular example is described for use in the frequency range from 1800 to 2200 megacycles per sec. and in which the voltage standing wave ratio in each of the guides 1 and 2 due to the coupling arrangement under matched termination conditions does not exceed 1.05. In the arrangement shown in Fig. 1 all the coupling sections 5 to 9 have the same physical length L, but the end sections may be slightly longer so as to give them the desired electrical length when allowance is made for discontinuity effects. In the arrangement shown in Fig. 1 the coupling sections 5-9 open into the broad walls of the guides 1 and 2 and are in series therewith. Alternatively the coupling sections can open into the narrow walls of the guides and be in shunt therewith, the mathematical relation then referring to characteristic admittances of the coupling sections. Comparison with a " binomial " arrangement is discussed.

Filed: 1963-05-03
Abstract: 1,007,513. Die casting machines. MATHER & PLATT (SCOTLAND) Ltd. April 21, 1964 [May 3, 1963], No. 17519/63. Heading B3F. In a pressure die casting machine a device is provided to effect two-stage pneumatic control of the injection plunger movement during injection of metal into the die. The device comprises a slide valve 25 which alternately permits the supply of compressed air above and below the piston 16 to effect upward and downward movement thereof, and a pneumatically operated check valve 38 which in association with needle valves 34a and 35a controls the flow of compressed air to the cylinder 17. Solenoid valves 37 and 39 effect actuation of the slide and check valves respectively. Means for controlling the length of stroke of the piston 16 is provided in the form of a rod 42 which is biased pneumatically in contact with the piston. The rod actuates a limit switch 46 by means of an adjustable trip 44 which energizes the solenoid of valve 39. When solenoid valve 37 is actuated the slide valve 25 operates to permit compressed air to pass via chamber 27 and 21 and valve 34a into the top of the cyclotron cylinder 17 causing downward movement of the piston 16 and plunger 14. Since the air admission to the cylinder is via needle valve 34a, this initial movement of the piston and plunger is slow, but as the piston descends the limit switch 46 is actuated by the trip 44 on the rod 42 which operates valve 39 to open the check valve 33a which permits a sudden increase in pressure on the piston and plunger which forces molten metal into the die cavity. Timing means (not shown) is incorporated so that the downward injection stroke of the piston and plunger is terminated after a predetermined time by the actuation of the solenoid valve 37 which actuates the slide valve 25 so as to supply compressed air to the underside of the piston which is retracted to its uppermost starting position. The return movement is controlled by adjustable valve 35a. Means are provided by a pressure sensitive switch 48 to prevent the dies of the machine opening if there is any pressure above the piston 16.
