Title: Electrophoretic Separation Apparatus
Inventor: PHILPOT JOHN ST LEGER
IPC: G01N27/447
Filed: 1965-02-05
Abstract: 1,150,722. Electro-phoretic separation. NATIONAL RESEARCH DEVELOPMENT CORP. May 4, 1966 [Feb. 5, 19651, No. 5213/65. Heading C7B. A method of electro-phoretic separation includes the steps of providing a main stream of restricted thickness of migrant-containing electrolyte, establishing a potential gradient across the thickness of the main stream and selectively removing separated fractions of the migrant from the main stream, the restricted thickness of the main stream being sufficiently small substantially to prevent turbulence in the electrolyte and the migrant. The migrant may be dissolved or suspended in the electrolyte and may consist of a mixture of proteins or biological cells or dye stuffs. Fig. 1 shows an annular main flow channel 8 whereas Fig. 4 (not shown) illustrates a planar main flow channel, the channels having porous walls. The migrant flows upwardly through the channel 8 between electrodes 16 and is electrophoretically separated into fractions which are taken from the apparatus at 23, 24 and 21. The migrant is introduced into the main flow channel 8 through a porous disc 19 and during its flow through the channel 8 is bounded by inner and/or outer dilute electrolyte layers introduced into the main flow channel 8 through inlets 17 and 18. The migrant and these layers together provide the main stream of migrantcontaining electrolyte. Further inlets and outlets supply concentrated electrolyte to and remove it from electrode chambers 6, 10. Some electrolyte percolates from the electrode chambers into the main flow channel 8. Fresh dilute electrolyte is supplied into the main flow channel at 20 and is arranged to be greater than the total liquid removed at outlets 23 and 24. Additional dilute electrolyte may be supplied through inlet 22 to prevent turbulence. As an alternative to feeding the migrant and dilute electrolytic liquids through porous walls, an arrangement such as illustrated in Fig. 3 (not shown) may be used. Outflow channels from the main flow channel 8 may be designed similarly. Amongst materials specified for the porous walls of the channel 8 are sintered acrylic or polystyrene granules. Gas bubbles in the concentrated electrolyte in the electrode chambers may be kept small by the addition of a small quantity of detergent. Foam so produced may be dispersed by a foam dispenser such as n-octanol or n-hexanol. In order to know through which exit feeds the migrants are going, they may be observed by absorption or scattering or refraction of light.

Title: Improvements in thermionic valves
IPC: H01J21/20
Filed: 1933-02-24
Abstract: 415,441. Thermionic valves. M-O VALVE CO., Ltd., Marconi House, Strand, London, and JACKSON, J. F., c/o General Electric Co., Wembley, Middlesex. Feb. 24, 1933, No. 5725. [Class 39 (i).] In a multiple valve in which a diode and a triode have a common cathode, the heating element for the cathode is so constructed that the energy dissipated per unit area is greater in the part of the element near the anode of the diode than elsewhere, whereby the end of the cathode emitting electrons to this anode is not cooler than the main part of the cathode. A heating filament for an indirectly-heated cathode is made thinner at the end near the diode, or the coils of a helical element are disposed closer together ; a directly-heated cathode may be made thinner at the end. A system with more than three electrodes may be used instead of the triode.

Title: Radar apparatus with variable pulse recurrence frequency
IPC: G01S1/02
Filed: 1954-02-26
Abstract: 753,035. Radar. NAAMLOOZE VENNOOTSCHAP HOLLANDSE SIGNAALAPPARATEN. Feb. 26, 1954 [Feb. 27, 1953], No. 5745/54. Class 40 (7). In a radar apparatus having a scanning beam aerial system the angular velocity of which varies in the course of the scanning cycle the pulse recurrence frequency of the radar transmitter is arranged to vary in correspondence with the variation of angular velocity and in the same sense. This enables the whole scanning operation to be completed in a shorter time without overheating the transmitting valves although the latter may be called upon to dissipate energy greater than the permissible average value during that part of the time when the scanning beam velocity is highest. It may be arranged that the pulse recurrence frequency is proportional to the angular velocity as, for example, by using the scanning motion drive to control a device for adjusting a variable resistor, inductor or capacitor forming part of the modulation oscillator circuit. However, the modulator preferably consists of a directly driven mechanical generator as, for example, a disc with commutator segments having the right distribution driven in synchronism with the aerial scan. Other types of mechanical generators such as slotted discs or drums controlling the light falling on a photo-electric cell or discs carrying suitably distributed means for influencing the flux in a stationary magnetic circuit can also be used. A magnetic recording device, either wire, tape or drum, on which the pulses are recorded and picked-off as the recording medium is driven is also a possible modulation pulse source. It is not essential that the mechanical pulse generators referred to above should have their pulse producing units arranged irregularly. They may be constructed so that the number of pulses produced per unit of displacement is constant and driven at a variable speed in accordance with the variable angular velocity of the aerial beam scan. Arrangements must be made to prevent overheating due to the maximum average pulse repetition rate being exceeded for too long and to prevent the pulse recurrence frequency dropping below a certain minimum value. It is not essential for the pulse recurrence frequency to be proportional to angular velocity of the aerial beam; it may be made to vary in steps according to the angular velocity. In a limiting case the scan may include a part covering a desired area and a part directed outside that area wherein the scan may change direction. In such a case the velocity of scan over the desired area may be substantially constant and the pulse recurrence frequency constant; the velocity of the scan outside the area will be less and the pulse recurrence frequency zero. The invention may be applied to the aerial scan arrangements described in Specifications 753,038 and 753,039.

Abstract: 372,851. Pressure-regulating valves. HORSTMANN, F. O., HORSTMANN, P. F., and HORSTMANN GEAR CO., Ltd., Newbridge Works, Bath. Feb. 24, 1931, No. 5755. [Class 135.] A pressure regulator comprises a vertical cylindrical bore 1 having an outlet 4 at its lower end and an upper part 10 of larger diameter in which a control piston 11 reciprocates. The latter is subject to outlet pressure introduced through an axial passage 12 in a piston valve 2 working in the bore 1 and connected to said control piston, inlet ports being provided in the skirt of the piston valve 2 and in the bore 1. Fluid entering the lateral inlet 3 passes to an annular porting 5 and through ports 9 in the piston valve 2 to the outlet 4. The lower end of a rod 13 integral with the piston 11 is connected to the piston valve 2 by a universal joint or swivel 14. The downward movement of the pistons is limited by a band 8 on the piston valve 2, the ports then being in register. A conical or similar surface 19 formed in the piston valve 2 causes the incoming fluid to produce an ejector effect at the lower end of the passage 12, said ejector effect increasing the set pressure on the controlled side in proportion to the volume of fluid passing through the regulator.

[Class 100 (ii)] A wire gauze stencil for printing on fabrics by the screen-printing method is manufactured by forming a photographic positive on the gauze, coating the gauze with a metallic paste adapted to fill up the meshes of the remaining parts, removing the insoluble gelatine to expose the parts of the gauze forming the positive, and finally strengthening the filled-up reserve parts by electroplating one or both sides of the gauze. The metallic paste may consist of finely powdered metal such as aluminium or copper suspended in a vehicle having a cellulose base. When electro-plating the wire gauze, which is stretched in the usual frame, the plating may be extended up to the inside edge of the frame so as to form a joint adapted to prevent the dye from infiltrating between the gauze and the frame.

Convention date, Feb. 22, 1933. [Class 98 (i)] [See also Groups XL and XXXVI] Fluorescent screens of cathode-ray tubes are made electrically conductive by applying between the screen-carrier or glass wall and the fluorescent layer a thin metal layer by cathodic sputtering, the distance of the sputtered cathode from its associated anode and the screen-carrier being 1 cm or less. With this small spacing and with a low sputtering voltage, the metal atoms do not penetrate into the wall but form a transparent conductive layer on its surface, and a television image can be observed through the layer and wall. The sputtered cathode is of the same size and shape as the screen. The anode during the sputtering is a ring or a metal net which is close to the screen and which may be moved to and fro during the sputtering to obtain a uniform layer. During the sputtering, the electrodes are cooled by cooling ribs or water circulation or by cooling the outside of the tube, and a hydrogen pressure of 10<-2> mm. is maintained by introducing hydrogen through a pipe to the middle of the cathode and evacuating it from the neck of the tube by a regulable pump.
