Title: A method of separating yeast by centrifugal treatment
IPC: C12N1/02
Filed: 1938-11-28
Abstract: 503,307. Centrifuges. AKTIEBOLAGET SEPARATOR. Nov. 28, 1938, No. 34576. Convention date, Dec. 1, 1937. [Class 23] During the treatment of yeast in a centrifuge the air, which is mixed with the yeast concentrate when the latter is thrown out to its collecting vessel and which is discharged with the concentrate, is separated from it and brought back to the collecting vessel. The bacteria are absorbed from the air by the early concentrate and the air is afterwards free from harmful organisms. The concentrate leaves the bowl of the separator 1 through nozzles 9 and passes to the collecting vessel 10; splashing is prevented by the downwardly directed air current through the slot 11. The concentrate then passes through the pipe 2 to the closed tank 3 where the air separates and flows through the pipe 8 back to the centrifuge casing, and then passes through the slot 11 to the collecting vessel 10. A valve 4 with a float 7 controls the outflow of the yeast concentrate from the tank 3. Where a number of centrifuges are used a separate tank may be associated with each centrifuge or a common tank may be used for all the centrifuges.

Title: Improvements in or relating to windscreen cleaning apparatus
Inventor: D ALBA ANTHONY RUSSELL
IPC: B60S1/48
Filed: 1964-08-26
Abstract: 1,080,497. Windscreen cleaning systems. TRICO PRODUCTS CORPORATION. Aug. 26, 1964 [Aug 26, 1963], No. 34976/64. Heading A4F. [Also in Division F1] In a windscreen cleaning system the pump 32 (see Division F1) is actuated in one direction by a cam driven by the windscreen wiper motor and in the other by negative or positive pressure applied to the underside of the pump piston, the arrangement being such that the pump piston actuating mechanism is clear of the drive cam when the pump is not in operation. As shown the windscreen wiper blades 18 are driven by an oscillating motor 20 which also drives a cam for actuating the pump. A control 78 connects a pipe 75 either to a source of negative pressure e.g. the manifold 73 or to atmosphere, the pipe 75 being connected through a timing device 77 to the pump and to a device 83 for starting the motor 20. When the pipe 75 is connected to atmosphere the pump stops at once but the timing device 77 restricts the flow to the starting device 83 so that the motor continues to operate the wiper blades for a set period after the pump has stopped. In a modification the pump drive cam is driven through gearing from a rotary motor and in a further modification the pump drive cam is mounted on the shaft of one of the wiper blades.

Abstract: 1305747 Aircraft control system TEXTRON Inc 20 July 1970 [8 Aug 1969] 35085/70 Heading B7G An aircraft control system comprises a plurality of control surfaces 12, 14 and 16 controlled by pilot-controlled means, and a plurality of stabilizing surfaces 18, 20 and 22 controlled by actuators 60, 62 and 64 respectively which are responsive to signals from stabilizers 72, 74 and 76 which sense instability of the aircraft, and comparator means 92 which detects non-comformity of any of the actuators and causes the or each non-conforming actuator to be disabled. The comparator 92 may also detect and disable a non-conforming stabilizer. Disabling of any member is indicated to the pilot on the control panel. By non-conforming is meant that a member produces signals which differ from those from the other members, or which lie outside predetermined signal limits stored in the comparator. The actuators may be hydraulic or pneumatic servo mechanisms and the signals from the stabilizers, via lines 84, may be hydraulic or pneumatic, or may be electrical. A single stabilizing surface may be able to effect stability control; in the event of all the stabilizing surfaces being disabled flight control is effected by means of control surfaces 12, 14 and 16 which are under direct duplicated manual control. The control and stabilizing surfaces may be on an aircraft wing, or may for example be on the rotor of a helicopter. (For Figure see next page.)

Patent GB-1302570-A (GB)
IPC: G01J3/42
Filed: 1970-07-20
Abstract: 1302570 Double beam absorption spectrometry COMPAGNIE D'APPLICATIONS MECANIQUES A L'ELECTRONIQUE AU CINEMA ET A L'ATOMISTIQUE 20 July 1970 [21 July 1969] 35137/70 Heading G1A The ratio of the transmission coefficients, K 0 /K 1 , of a sample channel 10 and a reference channel 11 for a particular infrared wavelength, selected by a stepping monochromator 3, is determined by first setting a mirror 24 to direct radiation through the sample to a photo-cell b and integrating the output for a time (T 0 ) until a fixed value E is reached, and then altering the mirror position to direct radiation, through the reference channel 11 for a time (T 1 ) until this fixed value E is again obtained, the ratio T 1 /T 0  being equal to K 0 /K 1 . This ratio is displayed on a pen recorder 9, plotted against the position of the grating 13 of the monochromator. The grating is stepped on to a new position after each pair of measurements for a single grating position. The radiation is initially filtered and passed through a rotating slotted chopping disc 2, and the detector is tuned to the chopping frequency. The detector circuitry Fig.2 (not shown) includes an integrator (71) operative to integrate the detector output from both channels. During each timing interval T 0 , T 1  this integrator (71) actuates a multivibrator (91) to produce a corresponding output pulse. The first and second timing pulses are stored in two timing integrators (72, 75 respectively). By employing further integrators (73, 74) in the circuit, the eventual output from the second timing integrator (75) is arranged to be proportional to the ratio T 1 /T 0 . A logarithmic matching device (20) is provided to give, in addition, the function log T 1 /T 0 , i.e. the relative optical density of the two channels. The second timing integrator is also by-passed to give a record of just the "single-channel" absorption of the sample. A single programmer unit (30) switches the integrators from their "storage" to their "measuring" mode, and also resets them to zero at the appropriate point of the measuring cycle. This programmer also controls the movement of the grating and the mirror. In a second embodiment Fig.4 (not shown) the detector output from the first channel is integrated for a known fixed time, T 0 , and the integrated output is stored. The second part of the cycle then merely involves using a timing integrator (78) to measure the time taken for the second channel to accumulate the same integrated intensity. The timing integrators may be replaced by timers supplied from a clock pulse generator.

Abstract: 1,261,678. Primable cell. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 21 July, 1970 [1 Aug., 1969], No. 35376/70. Heading H1B. A sealed deferred-action cell assembly comprises (a) a cell enclosing the electrode in an inert gas atmosphere, (b) a liquid reservoir containing priming fluid, (c) a liquid duct from the bottom of the reservoir to the cell closed by a breakable partition, (d) a vent pipe from the top of the cell to the top of the liquid reservoir also closed by a breakable partition and (e) a priming device to rupture both partitions and enable the priming liquid to flow into the cell and displace the inert gas into the reservoir. The cell may be a lithium-cuprous chloride cell with lithium tetrachloroaluminate dissolved in methyl chloroformate as electrolyte. The priming fluid may be electrolyte, the inert gas may be argon and the partitions may be of stainless steel or tantalum. In a particular embodiment (Fig. 2), two or more cells 16 in a line perpendicular to the paper are supplied by a single reservoir 19, via manifold 20. Gas manifold 14 connects the cells to vent pipe 25. The assembly is primed by depressing plunger 35, rupturing aluminium disc 36 and releasing lever 40 from spring clip 42. Continued depression of lever 40 presses down tubular plunger 28 within sealing ring 29, rupturing partition 27 and eventually acting upon a second tubular plunger 30. At rest upward movement of plunger 30 is prevented by stainless steel ring 53 and downward movement is prevented by expandable P.T.F.E. ring 51, but on application of downward pressure ring 51 expands and the plunger descends rupturing partition 22. Liquid is now able to flow into the cell via apertures 46 and 47, tubular plunger 30 and manifold 20, displacing the inert gas into the reservoir via manifold 14, pipe 25, aperture 45, (now suitably aligned) tubular plungers 28 and 30 and apertures 48.

Filed: 1920-12-20
Abstract: 155,762. Rheinische Metallwaarenund Maschinenfabrik. Dec. 23, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Buffers.-In a buffer for railway vehicles, the buffer and plunger casings are formed of seamless steel tubes, of the size of existing buffer casings, manufactured by pressing, drawing, or rolling and are flanged to enable the buffer plate and buffing-disk to be secured to them. The sides of the casings are slotted to form guides to receive the segmental ends of a disk on which the springs bear. The plunger casing b has longitudinal slots f which terminate near the open end of the casing. The metal at the end e of the slot f may be flanged and work in a slot d formed in the buffer casing a into which the segments i<2> of the disk g<1> also enter and prevent the plunger casing from revolving. Similar longitudinal slots on a diameter at right-angles to the diameter joining the centre-lines of the slots f may also be made in the front end of the plunger casing to receive the segments of a disk g<2>; extensions of these slots are made in the open end of the buffer casing a. A spring k<1> is placed under compression between the disk g<2> and the buffing-face c, and is inserted before, the latter is riveted to the tube b. The spring k<2> is also under compression and is inserted before the buffing-plate l is secured to the tube a. In buffing, the spring k<2> is compressed and on further compression the segments of the disc g<2> reach the bottom of the slot in the tube a and the spring k<1> is compressed. In a modification, one spring k<2> and one disk g<1> only may be used. In a further modification only one disk g' between the two springs k<1>, k<2> is provided which slides in slots cut in the buffer plunger b, the spring k<1> having an initial compression equal to or greater than the terminal compression of the spring k<2>.
