Filed: 1941-08-22
Abstract: 551,488. Mixing apparatus. MARSH, R. D. Aug. 22, 1941, No. 10738. [Class 86] An apparatus particularly for beating liquid glue into foam comprises a framework which can be moved about on rollers 20-22, and which supports a container 12 secured by spring clips 33 to a freely rotatable turntable 13, and a whisk or stirrer 47, 46 movable into and out of the container with its axis parallel to, but laterally displaced from, the axis of the container. The stirrer comprises lengths of metal rod passed through a tube 46 and bent to form skeleton blades, the tube being secured by a collar 45 to the shaft 15 of a motor 16, which is carried by a plate 44 adapted to be raised and lowered to move the stirrer out of and into the container by a cable 50 operated by a handle 53.

Title: Improvements in or relating to Voltage Controlled Negative Resistance Circuits
Inventor: GIBLIN ROGER ARTHUR
IPC: H03H11/52
Filed: 1967-03-08
Abstract: 1,175,895. Protective arrangements. R. A. GIBLIN. 7 May, 1968 [8 March, 1967], No. 10788/67. Heading H2K. [Also in Division H3] For use as a self-actuating protective switch responsive to an excessive value of V, the negative resistance region of the circuit of Fig. 5 is made as nearly as possible parallel to the current axis by reducing R2, the switch being self-resetting upon reduction of the voltage V. In a current limiting circuit, two circuits as in Fig. 5, one having a negative resistance approaching infinity, are connected in parallel across the voltage V (giving characteristic of Fig. 7, not shown); and two such pairs may themselves be arranged in parallel with reverse biased protective diodes between them (to give the characteristic of Fig. 8, not shown). The voltage controlled negative resistance circuit, Fig. 5, has a transistor T1 across the control voltage V, a second transistor T2 in the emitter base circuit of Tl and deriving its own base current from the voltage V through a variable resistance R2 which controls the value of the negative resistance (R, Fig. 1, not shown), and a third transistor T3, connected in series with T2 and in the base-collector circuit of T1. Transistor T3 has in its base circuit an e.m.f. source and a variable resistance R3 which controls the current peak (Ip) of the voltage-current characteristic, and may also have a collector resistor to control the slope of the initial positive resistance part of the characteristic. Instead of the transistor T3, there may be a F.E.T. or a M.O.S.T. with its gate open-circuited, or a drift or diffusion transistor with its base open-circuited, the current peak (Ip) then being fixed. In a further modification, the transistor T3 together with its base resistor R3 and e.m.f. source, may be replaced by a second complete circuit as in Fig. 5 (i.e. Fig. 11, connected in Fig. 10, at XX, not shown). The circuit thus acts like a tunnel diode.

Abstract: 636,527. Electric resonators. FREDHOLM, J. O. H., and CLAESSON, P. H. E. April 9, 1946, No. 10898. [Class 40 (viii)] A cavity resonator is tuned by moving a wall or a portion of a wall thereof by varying fluidpressure applied thereto. As shown, two resonators 1 and 2 forming a velocity modulation oscillator have flexible walls 3 and 6 which also form walls of fluid containing spaces 14 and 15.

Title: Improvements in distillation process
IPC: B01D3/12
Filed: 1937-04-19
Abstract: In a high vacuum distillation process, the undistilled residue from the still is circulated over the vaporizing element of the still. Apparatus for the process comprises a container 16 for the liquid, such as cod liver oil, which is drawn by a pump 56 through a strainer 48 and forced to a meter 58 from which it flows to an annular chamber 36 surrounding the vaporizing element 22 and provided with holes 37 through which the liquid flows down the outer surface of the element 22.  The distillate flows down the condensing surface 10 surrounding the element 22 and is drawn off by a pipe 43, while the residue drops through a cooling chamber 44 into the vessel 16, from which it is recycled over the element 22 until all required fractions have been distilled.  During each successive cycle, the temperature of the element 22 may be raised. High vacuum is maintained in the chamber 10 by pipes 39, 40, and during the first stage, gases and volatile <PICT:0479816/III/1> constituents are removed from the liquid.  The element 22 may be heated by an electric coil 35 controlled by resistances 30, 31, and the upper part may be heated to a higher temperature than the lower.  In another form the liquid is distributed by a row of perforated pipes arranged over a row of heating elements, and the distillate condenses on a row of angle plates arranged above the pipes, while the residue drops from the heating elements into perforated channels leading to the vessel 16. The distillate drops off the angle plates on to sloping channels leading to a draw-off pipe.  In another form, a series of vaporizers similar to that shown in Fig. 1 are used, each surrounded by a distributing annulus 36 and condensing surface 10 immersed in a cooling jacket. The process may use short-path high vacuum distillation and may be applied to animal and vegetable oils, fats and waxes, and may be used for the production of fat soluble vitamin concentrates. Specification 415,088 is referred to.

Filed: 1932-04-18
Abstract: <PICT:0395115/IV/1> Relates to modifications of the condensing system and of the devices controlling the movement of the air in the spinning cell of the parent Specification.  The condenser 16 is provided with an external cooling jacket 17, and it is connected to the spinning cell at a point 14 above the level of the spinning jet 8, both of these modifications enabling the cooling surface to be increased and the efficiency of the condenser to be improved. The conical member used at the lower part of the spinning cell proper 2 in the construction of the parent Specification is dispensed with, and the relative strength of the two currents of air at this point is determined by an extension 4 adjustably sliding on the lower part of the cell 2.  Further, in order to ensure a transverse flow of the air emerging from the nozzle 11, there is fitted above the jet a diaphragm 12 having on the opposite side to the nozzle 11 an aperture 13 adjacent to and below the outlet to the condenser. Heat-insulating diaphragms are fitted at the points 15, 21, and at the former there is also provided a perforated diaphragm which serves to control the flow of air through the system.

[Class 80 (ii).] An automatic reversing gear includes a pair of clutches which are energized and de-energized automatically at predetermined alternate times by means of a hunting member of a rotary mechanism. Loosely mounted on a shaft 9 are three toothed wheels 12, 14, 17, the central wheel 14 being driven at a slightly different speed to the wheels 12, 17, from a gear 10 on a shaft 24. The wheel 14 has a series of rollers 15 engageable with cam faces 12a, 18a on the wheels 12, 17, the arrangement being such that the wheels 12, 17 are moved axially alternately to lock clutch plates 11, 19 to clutch members 31, 39, keyed to the shaft 9. A member 7 of the clutch 11 gears with a wheel 1 on the shaft 24 through an intermediate wheel 2, and the wheel 17 is fixed to a sleeve 43 loose on the shaft 9 and carrying a pulley or pinion. When the clutch 11 is energized the shafts 9, 24 rotate in the same direction, when the clutch 19 is energized the shafts rotate in opposite directions. Either shaft may be the driven shaft. In a modification the hunting wheel has two cam surfaces which engage rollers on levers pivoted to the wheels 12, 17.

Abstract: 968,170. Operating single indication receivers. CHARBONNAGES DE FRANCE. March 22, 1963 [March 24, 1962],No. 11536/63. Heading G4F. A control system for an alarm device 1 comprises a first transistor 3, normally biased to be cut-off, a second transistor 5 connected to the first, and a switch 13 normally connecting the bases of the two transistors, the arrangement being such that breaking the circuit between the two bases causes both transistors to conduct and actuate the alarm. In order to prevent tampering with the device, the unit containing the actuating switch 13 is connected to the transistor unit by a three wire circuit 8, 9, 10. If the wires are cut, the transistors become forward biased and the alarm operates. If the wires are shorted together transistor 3 is forward biased and the alarm will again operate.
