Title: Improvements in or relating to the separation-out of protein or material rich in protein from materials having a protein content
IPC: A23J1/14
Filed: 1944-10-06
Abstract: <PICT:0585058/IV/1> Material rich in protein is separated from a mass of particles including protein by subjecting a suspension of said particles in a liquid vehicle to a process of electrostatic precipitation. Thus, crushed or ground seeds are mixed with a liquid vehicle, suitably a vegetable oil solvent such as trichlorethylene or carbon tetrachloride, and the suspension thus obtained is subjected in an electrostatic separator to the action of an electric field whereupon the protein-containing matter separates out and is deposited on one of the electrodes from which it may be collected.  A suitable separator (see Group II) comprises a vessel 1 having an inlet 2, through which the suspension is supplied, a high potential negative electrode 4 in the form of a fine mesh screen or thimble on the end of a discharge conduit 11 for the effluent, and an earthed electrod 5 in the form of a conical wire cage.  In examples: (1) a quantity of finely divided ground nuts is mixed with trichlorethylene, allowed to stand and the liquid suspension then passed through the separator described above, a voltage of about 20 kvs. being maintained, so causing the protein to adhere to electrode 5 as a stiff mud which is removed and dried; alternatively, instead of the liquor flowing continuously through the separator, the suspension is treated in the separator for 5 mins. and the treated liquor then removed via run-off 13; (2) ground-nut protein meal is recovered as in (1) and then is mixed with clean trichlorethylene and retreated, thereby reducing further the oil content and increasing the protein content; (3) a protein meal is recovered as in (1) from a suspension of ground palm kernel seeds.  The separators described in Specifications 520,481 and 561,020, [both in Group II], may also be used.  The Provisional Specification describes, in particular, the recovery of protein matter from ground-nut mucilage, the residue obtained after expressed nut oil has been passed through the usual filter processes and examples are given illustrating such a recovery by methods similar to (1) and (2) above.

Abstract: 305,893. Formßnek, F., Zeman, L., Zeman, E., and Bartonicek, M. June 19, 1928, [Convention date]. Addition to 263,839. Aeroplanes ; helicopters ; propelling; steering and balancing.-A machine designed for vertical and horizontal flight as described in the parent Specification is modified by removing the elevators from the fuselage, by the addition of a plane movable with the airscrew at each end of the radial arms, and by reducing the planes carried by the central member to two. A central member having two radiating arms 11 is capable of rotating about or being locked to a pilot's cockpit 14 mounted on an undercarriage 13 provided with a rudder 16. The arms 11 carry motor and propeller units 21, 22 at their ends together with tiltable planes 23 which can be swung round with the motor and propeller units through 90‹ to convert the machine from an aeroplane moving in the direction of the longitudinal axis of the arms 11 to a helicopter wherein the arms 11 rotate about a central vertical axis. Two adjustable planes 18 are mounted on cheeks 17 of the central structure. A hollow column secured to the cockpit 14 extends through the central structure and carries an elevator 26 and a rudder 25 operable from the cockpit. The planes 18 can be tilted in the same or opposite directions by curved racks 35, Fig. 10, engaged by worms 37 on shafts 38 driven by chain gearing from gearing turned by a handle 39 and fitted with clutch operated reversing gear. A sprocket 49 on the same gearing is connected by a chain to a sprocket 59 on a shaft provided with a sliding bevel wheel 61 which can be moved into engagement with a bevel wheel 64 on a shaft 67. This shaft 67 is geared to a shaft 70 and both shafts have sprockets connected by chains to sprocket nuts 46, Fig. 4, for raising and lowering rods 43 connected to the planes 23. These planes are pivoted about brackets 81 carried by the motor casings which pivot around tubes 45 surrounding the rods 43. Each motor and plane unit is turned by the gearing shown in Fig. 13 when a wheel on the end of a tiltable shaft 83 is brought into engagement with a worm on the tail of the engine shaft. The shaft 83 drives a ring 92 having internal and external teeth which alternatively engage respectively two wheel 98, 97 on a tiltable frame 94. The wheels 97, 98 engage a wheel 95 on the pivotal centre of the frame 94, and this wheel engages teeth on a circular rack 96 on the end of the arm 11. A lock 76 engages a notch 74, or 75 in the two extreme positions of the unit. All of these movements are controlled from the cockpit by mechanism not described. During forward flight when the planes 18, 23 are parallel to one another the central structure is locked to the cockpit. During vertical flight the cockpit is unlocked, and the inner tips of the planes 23 which are now set radially are locked to the central structure. Specification 287,034 also is referred to.

Title: Transistorised bistable multivibrator
IPC: H03K3/286
Filed: 1965-04-27
Abstract: 1,099,955. Transistor bi-stable circuits. MOTOROLA Inc. April 27, 1965 [April 30, 1964 (2)], No. 17731/65. Heading H3T. A bi-stable circuit comprises an emittercoupled pair of transistors 18, 20, reciprocally coupled via emitter followers 10, 12, the circuit being directly coupled to the outputs of logic circuits in such a way that it is triggered when the signal amplitude reaches a predetermined level. As described, the emitter followers 10, 12 are always conductive and provide either high or low levels of negative output voltage at terminals Q, Q. In one state of the circuit, transistor 20 is conductive whilst 18 is non- conductive and assuming positive-going set, reset and clock inputs, transistors 30, 32, 34, 36 will also be conductive. The coincidence of negative reset signal at R and negative clock pulse at C 1  will cut-off transistors 34, 36 and pass a signal via emitter follower 40 to reset the bistable circuit 18, 20. The triggering signal is coupled to a tap 49 in the emitter load of transistor 12 so that the circuit is triggered when the signal amplitude passes through one half of its binary change. Transistors 50, 52 in the current-switching logic circuits should be provided with regulated bias voltages V BB . In Fig. 2 (not shown), transistors 50, 52 are omitted whilst transistors 30, 32, 34, 36 utilize the same emitter resistor as transistors 18, 20 and their collectors are connected to the collectors of the respective transistors 18, 20. Fig. 1 (not shown), relates to a circuit similar to Fig. 2, except that the emitters of the transistors 30, 32, 34, 36 are connected to a tapping point in the common emitter resistor 42. The invention is suitable for construction as an integrated circuit using a silicon substrate.
