Title: Improvements in or relating to the treatment of anaemias and similar conditions
IPC: A61K31/00
Filed: 1943-02-05
Abstract: A liver preparation for the treatment of an mias is obtained by digesting mammalian liver with papain at a pH value of 5.5 at 60 DEG C. for three hours, and then rapidly raising the temperature to 100 DEG  C. and boiling, say, for five minutes, to destroy the activity of the enzyme without destruction of the active principles of the liver.  The product may be filtered and concentrated to half its volume, again filtered through sterile kieselguhr, the filtrate &c. passed through a Seitz filter, and a solid product be obtained from the final filtrate by spray drying or removal of water at a low temperature under reduced pressure. According to the Provisional Specification, other enzymes such as pepsin, trypsin, or bromelin may be used in the process, and their destruction effected by means other than heat; and the digestion may take place at a pH value of 5-5.5.

Inventor: FIRTH DONALD
IPC: G01N7/14
Filed: 1957-01-18
Abstract: <PICT:0832085/III/1> The amount of air or other gas entrained in a liquid is measured by an apparatus comprising a chamber for the liquid which is connected to a container full of discrete pieces of solid material and means provided whereby the liquid can be poured over the large surface area of the solid pieces in the container which has been evacuated and pressure of the gas occluded and released is measured by means of a monometer attached to the container.  A metal bottle 11 is connected in fluid-tight relationship with the vessel 19 which contains steel balls and rollers 22 commonly used in distillation columns.  The vessel 16 which encloses vessel 19 is mounted with a clamping collar 35 so that the vessel can be conveniently inverted about a horizontal diametrical axis at the suitable moment.  The connections of the pump 26 and the monometer 28 are flexible to allow for this inversion. When the vessel is inverted the valve 32 opens under its own weight allowing the contents of the container 11 to flow through the bore 29 and holes 38 in the walls of the guide body 14 within the vessel 16 and thence through the wall of the inner vessel 19 and over the fillings.  The apparatus is particularly suitable for testing silicones, non-flam hydraulic fluids and oils with a pressure of 0.0-0.05 millimetres of mercury in the apparatus using 4 to 5 cubic inches of liquid.

Patent GB-1376742-A (GB)
Title: Position resolvers
IPC: G06F3/03
Filed: 1971-10-26
Abstract: 1376742 Detecting position MARCONI CO Ltd 26 Oct 1971 [16 Jan 1971] 2223/71 Heading G4H The position of a member movable over a co-ordinate array of strips is determined by detecting movement of the member by an optical sensor.  In the embodiment of Figs. 1 and 2, in which lines are painted, etched or scratched on or wires are positioned on or embedded in for example a glass plate 1, the member is a light pen 4 and the optical sensor comprises two photo-cells 5, 6; 7, 8 for each co-ordinate direction X, Y. The photo detectors are connected to circuits 10, 11, 14, 15 arranged to detect the direction of movement in accordance with which detector in each pair is first energized as a line is crossed by the pen, the circuits pulsing add or subtract inputs of X, Y counters to give binary coded counts representing the position of the member.  In the embodiment of Fig. 3 (not shown) the lines comprise strips reflecting (for the X direction), blue and green light and (for the Y direction), green and red light. The pen comprises two bundles of light fibres, one leading to a light source and one to photo detectors responsive to blue, green and red light. The detectors are connected to logic circuitry so that as in the embodiment of Figs. 1 and 2, the amount and sense of movement may be represented by the count in two counters. In a modification of this embodiment the lines consist of strips reflecting green and all light and red and all light so that only two photo detectors are necessary. Instead of utilizing two bundles of light fibres, light may be transmitted from a source (20, Fig. 10, not -shown), through a semisilvered mirror (53) on to a light guide (18) connected to the movable member and light from the guide is reflected by the mirror to a photo detector assembly (21). The bundle may consist of a central fibre surrounded by six fibres placed at the corners of a hexagon, the six outer fibres being used for illumination and the inner fibre for carrying the reflected light to the detectors. Dichroic filter mirrors may be used to separate the colours in the reflected light. In an alternative embodiment (Fig. 13, not shown), each line is of coded form comprising a stripe (57) reflecting all light and a plurality of stripes (58-61) reflecting (for the X direction) red light and (for the Y direction) green light. The first and last stripes (47, 61) are wider than the rest. The strips may be so positioned that as they are scanned the pulses between the wide pulses represent the position of the member in binary form.

Abstract: 1464442 Photographic materials and their use as originals THOMSON CSF 17 Jan 1974 [18 Jan 1973] 02288/74 Headings G2C and G2X A photographic material comprises (a) a support, (b) a photo-resist layer and (c) a non-metallic film or a film of Bi, Zn, or Cd which absorbs radiation to which the photo-resist is sensitive and which on heating undergoes residue for evaporation. The specified non-metallic film is polymethylmethacrylate which depolymerizes on heating and a dye is added to absorb the radiation. The material may be imagewise exposed to a laser or electron beam or particles, optionally controlled by an electrical modulating signal, to evaporate the film by heating the exposed areas. The remaining film now acts as a mask for exposure of the photo-resist which is developed after such exposure to produce a relief pattern. The material may be used to record video frequency signals.

IPC: G01L9/00
Filed: 1953-01-27
Abstract: 724,401. Measuring fluid pressure electrically. MAIHAK AKT.-GES., H. Jan. 27, 1953 [Feb. 9, 1952], No. 2357/53. Class 40 (1). A pressure sensitive element responsive to fluid pressure in the presence of a pressure exerted by solid material which has no effect on the element, e.g. a probe adapted to respond to liquid pressure in the soil, comprises a diaphragm 1 protected by a sintered metallic filter 2. The filter is of such fine porosity that the external liquid pressure is quickly applied by capillary attraction to the diaphragm which is spaced from the inner end of the filter by a distance of capillary size. The resonant frequency of a tensioned wire 3 secured at one to the diaphram and maintained in oscillation by an electromagnet 4, varies with the fluid pressure which is measured remotely by measuring the frequency of the current supplied to the magnet 4 to maintain resonance.

Title: Improvements in wrapping machines

Abstract: 969,797. Feeding webs. J. W. J. GREGORY. May 1, 1962 [Jan. 23, 1962], No. 2395/62. Heading B6B. [Also in Division B8] In a wrapping-machine of the type described in Specifications 453,165, 542,234, 551,523, 566,702, where wrapping web is drawn off a reel in amounts corresponding to the girth of an article being wrapped together with an overlap, a photo-electric monitor is positioned to monitor registration marks spaced on said web at intervals corresponding to the length of a single wrapper, so that, should a larger article take more web and cause a second registration mark to pass beneath said monitor, means is actuated after severing to draw back the free end of said web a fixed amount. In this manner a more consistent positioning of the wrapper pattern on the wrapped article is obtained. Each article passes along conveyers 2, 4 on to a platform 8, thereby catching an end 6a of web therebeneath and drawing it from the reel, and is moved upwards, a roller 10 meanwhile moving to draw the web down to provide an overlap, the roller being initially adjusted to give a greater overlap than normally required, whereafter a blade 11 severs the web. The article is then pushed off the platform by a member 9 and conveyed past further folding and heatsealing means (not detailed).  If a second mark passes under the photoelectric monitor 12, indicating that a prearranged length of wrapper has been exceeded, a signal transmitted by the monitor will be stored by cam-operated switch means (Fig. 3, not shown) to cause the web to be clamped by solenoid-operated members 16, and a roller 15 to push it down a fixed amount between rollers 14, thus drawing back the free end 6a, and also reducing the amount of overlap provided at the next wrapping operation. The stroke of roller 15 may be varied.  Specification 969,798 also is referred to.
