Patent GB-616267-A (GB)
Title: Improvements in or relating to the production of substantially oxy- and photo-stable biologically active pigment units and constituents thereof from raw plant material
IPC: A61K36/81
Filed: 1945-09-11
Abstract: Biologically active photo- and oxy-stable plant pigment units are prepared from raw plant material by forming from such material a hydrosol of colloidal dispersoids containing pigment protein and lipin constituents, filtering, separating the plant pigment units from the hydrosol by centrifuging or by electro-dialysis, and drying the pigments under careful conditions.  The mother liquor from which the pigments have been separated may, if desired, be further treated to separate cytoplasmic plant protein.  The raw material such as fresh leaves, raw vegetables or fruits is washed to remove surface dirt, then chopped into small pieces and finally ground in a colloid mill with a small quantity of distilled water. The filtration step which follows is carried out through paper or a fritted glass filter. If the pigment units are to be separated by centrifugation the so-called super-centrifuges which revolve at 2900 r.p.m. are used. If electrodialysis is used, collodion sacs are employed as the dialysing membrane, the hydrosol being on one side of the membrane and distilled water on the other and a current of 110 volts and 1.8 to 2 amperes is passed.  The drying is preferably carried out in dry air at about 30 DEG  C.  The dried pigments so obtained may be further separated by selective-solvent partition or by chromatographic adsorption. Examples are given starting with spinach, parsley and tomato, and a description of the therapeutic uses is included.

Abstract: 1454902 Image converter tubes AGFA-GEVAERT 8 May 1974 [21 May 1973] 24166/73 Heading HID A radiation-e.g. X-ray-image is recorded as an electrostatic charge pattern on a removable sheet of insulating material mounted in an envelope maintained at a gas pressure of less than 10<SP>-3</SP> torr, by irradiating a photocathode 40 with the image and accelerating the resulting electron image through a channel multiplier 41 on to the resin recording sheet 42, which is subsequently removed from the envelope to permit development on transfer of the electrostatic image. As described, the photocathode 40 is of lead or uranium on an aluminium sheet 44; the channel multiplier is mounted less than 0À3 mm. from the photocathode by means of insulators 49 and clamps 48 which permit application of a potential difference across the multiplier; and the resin sheet 42 may be coated with a transparent or semi-transparent layer 43, e.g. of aluminium or copper iodide. Modified arrangements referred to include: the support of the channel multiplier from the photocathode by an interposed microchannel plate of material which is electrically insulating and may be secondary electron emissive, and of which the channel openings contacting the photocathode surface are larger, e.g. by a factor of 5, than the electron multiplier channels; the channel multiplier may be tilted through an angle of up to 10 degrees with respect to the normal to the photoeathode surface; to increase multiplication the input base of the channel multiplier may be coated with a transmission secondary electron multiplying material, e.g. zinc sulphide, potassium chloride, potassium bromide, magnesium fluoride, or calcium fluoride; and the photocathode may be responsive to an infra-red, visible, or ultraviolet image, which may be produced by the incidence on a contacting phosphor layer (55, Fig. 2, not shown) of an X-ray, gamma ray, beta ray, fast electron, or neutron image. A variety of known methods for finally effecting the development of the electrostatic charge pattern produced on the resin sheet 42 are referred to.

In a vibrating contact regulator for a shunt wound D.C. generator, a transistor is interposed between the contacts and the field winding, thereby reducing the current handled by the contacts. A transistor 10 is connected in common emitter mode in series with the field winding F across the armature G and is rendered conducting when the contacts of the regulator 12 open and remove the negative base bias. In a modification, Fig. 2 (not shown), the contacts of the regulator close at the regulated voltage, so the biasing polarity is reversed. In other modifications, Figs. 3 and 4 (not shown), the transistor in series with the field is connected in common collector mode, and the base bias is controlled either by a single vibrating contact regulator which includes a load current limiting winding; or by separate voltage and current regulators so as to give two-stage regulation.

Title: A method and apparatus for bottling completely sterile liquids particularly milk
Inventor: ENOCK ARTHUR GRAHAM
IPC: B67C7/00
Filed: 1963-06-20
Abstract: 1,016,360. Sterilizing and filling bottles. GRAHAM ENOCK MANUFACTURING CO. Ltd. June 17, 1964 [June 20, 1963], No. 24536/63. Heading B8T. A method of bottling a completely sterile liquid e.g. milk comprises subjecting partially sterile bottles to external steam treatment, whilst they are sealed to steam but open for the release of air, until the bottles are completely sterile internally, and then admitting the completely sterile liquid. The bottles 5 are passed singly from a conveyer to one of a series of pedestals 8 continuously rotating on a rotary table, the pedestal then being in its lower position. When the pedestal is raised together with the bottle 5 which is to be sterilized, the bottle is lifted into a steam chamber 3, a surface 11 of the pedestal sealing the bottom of the steam chamber whilst the top is sealed by a filling valve 4. There is one valve device 4 with depending chamber 3 for each pedestal and bottle. When the bottle is lifted into this position and engages a rubber seal 29 a spring loaded slideable cup 27 is lifted and the lower end of a sleeve 24 slideable on a container 18 projects into the neck of the bottle, the sleeve being forced by a spring 25 against a relatively fixed mushroom valve 23 in order to prevent milk from leaving the container 18. Thus the valve device seals the bottle interior to steam but allows release of air through a passage 30 with a non-return valve 31. On continuing the rotation of the turntable, a steam inlet valve 13 is opened and steam supplied, a steam outlet valve 16 being closed after a few moments so that a steam pressure builds up and the bottle interior is completely sterilized. When the sterilization is completed a cam follower 32 engages a stationary cam 33 to lift the valve sleeve 24 away from the mushroom head 23 and thus fill the bottle with a measured quantity of milk. Immediately after filling is initiated, the steam inlet valve 13 is closed and at some point during filling the steam exhaust valve 16 is opened. After filling, the sleeve 24 lowers to close the passage around the mushroom head 23 of the valve 4 and the pedestal 8 together with the bottle 5 is lowered and the cup 27 returns to its lower position. After leaving the steam chamber and until it reaches the capping section, the bottle neck passes under a hood into which sterile air under pressure is continuously introduced.
