Title: Improvements in or relating to multivibrator circuits
Inventor: BAXANDALL PETER JAMES
IPC: H03K3/08
Filed: 1952-10-16
Abstract: 733,186. Pulse-generating circuits. MINISTER OF SUPPLY. Nov. 16, 1953 [Oct. 16, 1952], No. 26008/52. Class 40 (6). A multivibrator comprises an amplifier having positive and negative feedback paths which cause the amplifier to make rapid excursions from one condition of overload with a positive input voltage to the other condition of overload with a negative input voltage, the excursions being separated by a time interval. The Figure shows a multivibrator comprising the cathodecoupled valves V1, V2 in which a negative feedback path is established between the anode and grid circuits of the amplifier stage V2 by the resistors R6, P1 and in which a positive feedback path is established between the control grid and cathode of this stage by the phasereversing valve V1 and capacitor C1 When the voltage at terminal 1 increases positively due to the positive feedback circuit the amplifier stage V2 is rapidly overloaded in a positive direction and remains so whilst capacitor C1 discharges towards the negative voltage of terminal 2. When the voltage at terminal 3 falls below the overload limit the negativegoing waveform at 3 is amplified and due to the positive feedback the amplifier rapidly overloads in the negative direction. Capacitor C1 now discharges towards the positive voltage at terminal 2 until the voltage at 3 rises above the negative overload limit, when the positivegoing voltage at 3 is amplified and the cycle is repeated. Thus the mark/space ratio of the generated waveform is determined by the voltage of terminal 2 relative to terminal 4 which can be varied by adjustment of potentiometer P2. The frequency of the multivibrator may be adjusted coarsely by switching in different values of capacitor C1 and variation of potentiometer P1 may provide a fine control. The multivibrator may be synchronized by applying the synchronizing signal to the grid of valve V1 and pentode valves may be used to give the amplifier a higher gain. The common cathode resistor R4 may be replaced by a constant-current valve and a push-pull output may be taken from the multivibrator. In a modification the amplifier gain is increased by using a two-stage amplifier each stage comprising a long-tailed pair with a constant-current source serving as a cathode impedance for one of the stages.

Filed: 1960-07-28
Abstract: <PICT:0958580/C3/1> In obtaining edible oil and substantially dry edible protein meal, e.g. containing less than 10% by weight of water and less than 10% of oil or fat, from fresh oily proteinaceous material, such as nut kernels, soybeans, cotton seeds, fish and animal meat, the material is mixed with free oil similar to the oil it contains, and divided into discrete particles then dried, without risk of burning, at a temperature below 212 DEG  F. and a pressure below atmospheric pressure, and finally pressed to expel most of the oil and leave protein meal.  As exemplified, pieces of fresh wet coconut kernels mixed with free coconut oil are ground in a grinder 3 and the resulting mixture is pumped through a pipe 6, a preheater 7 and a pipe 9 into a heated drying chamber 11 maintained at reduced pressure by suction applied through a pipe 14, a condenser 13, a pipe 16 and a catchall 12.  The temperature in the preheater 7 and chamber 11 may be 180 DEG  F. The dried mixture, e.g. containing less than 5% of water, is then pumped, by a pump 24, through pipes 19 and 26 on to a screen 27, preferably a shaking screen, where oil drains away and is pumped, by a pump 33, through a pipe 34 and a filterpress 36 into storage.  The remaining material is then fed into a screw-press 28, e.g. of the type described in U.S.A.  Specification 2,004,408 or 2,149,736, from which protein meal, e.g. containing 5% of oil, is discharged through a conduit 29 into storage, and coconut oil is discharged, through a pipe 31 and a pump 32, into the pipe 34. Some of the oil from the pump 33 may be diverted, through a pipe 37, a cooler 38 and a spray 39, on to the exterior of the press 28 to cool it. The free coconut oil supplied to the grinder may come from the screw-press 28.

In a pneumatic motor of the type in which a vane or piston is oscillated or reciprocated in a cylinder by compressed air admitted alternately to each end of the cylinder, the other end being exhausted to atmosphere, by an automatic reversing valve, means are provided to restrict the area of the exhaust passage so that the air flow is reduced and a back pressure is created. The reversing valve (not shown) of a double-acting pneumatic motor is mounted on the motor output shaft 2 in a closed casing 3, to which compressed air is supplied, and oscillates with the shaft to alternately admit pressure air to one of two ports 5, 7 respectively communicating with opposite ends of the motor cylinder 1 and place the other port in communication with an exhaust port 6 leading via an opening 9 to an exhaust passage 13 in a body 11 attached to cylinder top. The free area of passage 13, which communicates with the atmosphere through an aperture 14 and filter 15, may be varied by an adjustable needle valve 16. In a modification the area of the exhaust passage is restricted by a ball valve which is provided in each of the passages leading from the reversing valve to opposite ends of the cylinder 1 and spring-urged towards a seating having notches therein, the arrangement being that the valve is automatically opened against its spring when pressure air flows through it into the cylinder and seated, by the spring and exhaust pressure to allow only a restricted flow through the notches in the seat when exhaust takes place.

[Also in Group XXIX] In vulcanizing rubber soles to boot and shoe uppers using a pneumatic press, an initially applied pressure is gradually increased, to allow air in the mould to escape more gently and to minimise burr formation, by using a threeway cock incorporating a mechanism for delaying the build up to full pressure in the press. In operation, a handle 7, Figs. 5, 6, adjusts the initially applied pressure by opening a valve 30 against the action of springs 31, 33, carried by flexible membrane 12. Pressure air through conduit 18 enters chamber 13 (which communicates with the press through conduits 19, 20) through valve 30, 301, 30<SP>11</SP>, to give the initial pressure in chamber 13. Valve 30 is then closed by flexible membrane 12, and the air pressure is gradually built up to full pressure by leakage through adjustable needle valve 28 and conduits 15 16. When vulcanization is complete the supply of pressure air is cut off by operating lever 4, Fig. 1, which, through link 5, depresses plunger 26, Fig. 6, and opens valve 25 to vent the chamber 13 through passages 23, 24 and 27 to the atmosphere.
