Title: Improvements in or relating to methods of, and apparatus for, determining colour values of illumination, more particularly in relation to colour photography
IPC: G01J3/51
Filed: 1934-10-22
Abstract: 446,016. Photometric apparatus. HARRISON, G. B., 23. Roden Street, and PURSLOW, E. T., Rodenside Laboratory, Roden Street, Ilford, Essex. Oct. 22, 1934, No. 30289. [Class 97 (i)] The colour values of illumination for colour photographic purposes are determined by measuring the relative proportions of predetermined colour components in a given light by testing the light for each predetermined colour separately by means of a photo-electric cell responsive, or rendered responsive, selectively to that component. In the form shown, the cells 17, 18, 19 are connected to galvanometers 23, 24, 25 which are shunted respectively by variable resistances 26, 27, 28. The resistances are capable of proportional variation by a single control comprising a toothed wheel 29 engaging wheels 30, 31, 32 connected, to the rotating arms of the resistances. The apparatus is primarily designed to enable the necessary filters for colour photography to be found for any illumination when those for a standard illumination are known. The standard filters 20, 21, 22 are placed in front of the cells and the standard illumination is allowed to fall on the cells. By means of the shunt resistances the reading of one galvanometer is adjusted to a predetermined value, e.g. 100, and the readings of the other two 'galvanometers noted. The light to be analyzed then illuminates the cells and again the reading of the same galvanometer is adjusted to 100, the composition of the light in relation to the standard being then deduced from the galvanometer readings. When rectifier cells are used the potentials developed by the cells may be balanced by the fall of potential across three resistances connected in series to the same potentiometer, thus making the potential falls proportionally adjustable.

Title: Improvements in or relating to tubular x-ray diaphragms
IPC: G21K1/06
Filed: 1948-11-23
Abstract: 654,807. X-ray apparatus. PHILIPS ELECTRICAL, Ltd. Nov. 23, 1948, No. 30355. Convention date, Nov. 26, 1947. [Class 98 (i)] In a limiting diaphragm for producing a narrow beam of X-rays by total reflection thereof at the walls of a tubular channel, the entry port d1, Fig. 3, and the exit d2 of the channel are of different sizes and the channel has a length l such that those X-rays entering the smaller port d1 which are inclined to the axis of the channel at an angle equal to the limiting angle of reflection of the channel wall material are reflected at least once. Preferably, the port d2 is not less than twice the size of port dl. Apparatus for the X-ray analysis of substances having lattice-plane spacings exceeding 100 Š may be provided with such a diaphragm. It is shown that at each reflection of a ray entering the diaphragm the angle between the ray and the axis of the channel becomes less, and may be made as small as desired by making the tube sufficiently long. The channel walls are made of material such as glass or vitreous enamel which does not emit secondary X-rays, or alternatively of material such as aluminium which emits secondary X-rays with a wavelength much longer than that of the primary X-rays, and are polished with material free from traces of substances which would give rise to secondary X-rays. If the X-ray beam originally includes rays of shorter wavelength than the predominant wavelength, these rays are largely removed, since the limiting angle of reflection decreases with wavelength. The channel is adjusted with respect to the X-ray source by turning it about the intersection of the axis with the plane of the entry aperture until the brightness of a screen placed on the exit side and struck by the beam is a maximum. A slot-shaped channel may be made by placing reflecting plates I and II, Fig. 4, having polished faces facing each other, on a plate III. Metal strips of thickness equal to the widths of the apertures are placed between the respective ends of plates I and II, a plate IV is placed over them, the four plates are stuck together, and the strips are removed. By using additional reflecting plates a multi-sided channel may be obtained.

Title: Improvements in or relating to the production of cheese
IPC: A23C19/05
Filed: 1952-12-01
Abstract: In making cheese, milk of low fat content is mixed with an acid-producing starter and then set to form an acid mixture of coagulated curds and whey, which are separated when the pH value of the acid mixture is between about 4.5 and 4.8 and its titratable acidity, expressed as lactic acid, is about 0.68 to 0.8 per cent, and when the compressibility of the curds is substantially at a maximum, i.e. when their compressibility factor is substantially at a minimum; the compressibility factor being the volume occupied by the compacted curds, expressed as a percentage of the total volume of the sample, after centrifuging a sample of curds and whey at 17,000 r.p.m. for 40 seconds in a 10 c.c. test tube.  The starter may be a low-acidity-producing culture and the amount of starter employed may be between 10 and 20 per cent of the volume of milk.  Calcium chloride and rennet may be added to the milk.  The mixture may be set at a temperature of at least 80 DEG F., e.g. between 86 and 92 DEG F., and it may be heated during setting or before separation, which may be effected at about 100 DEG F.  Albumins precipitated from previously separated whey may be added to the mixture.  The separated curds, e.g. blended with cream, may be heated to pasteurization temperature, homogenized with or without added milk solids and cooled.  Separation may be effected in a centrifugal separator having a rotating bowl with nozzles in its periphery (see Group II), through which nozzles the curds are discharged with two-stage pressure reduction and into which the aforementioned cream may be fed.  The nozzles help to homogenize the curds.

Title: Low dissipation logic gates
IPC: H03K19/084
Filed: 1965-07-19
Abstract: 1,110,066. Logic circuits. WESTINGHOUSE ELECTRIC CORPORATION. 19 July, 1965 [20 Aug., 1964], No. 30593/65. Heading H3T. In a logic circuit where the potential at a point depends on the potentials at input terminals connected to the point via transistors, the power dissipation is reduced by altering the bias on a control circuit between the point and the power supply through a semi-conductor device in accordance with the potential at the point. In a NOR circuit (Fig. 3) positive inputs are applied to the bases of transistors 53, 54, the presence of one of these inputs causing the output point potential 58 to be near earth. If neither input is present, point 58 will be at a higher potential (giving a significant output) and only then will transistor 60 be turned on to allow transistor 61 to pass current from the potential source to the outputs connected to 58. The transistors 60, 61 may be replaced by a PNPN device. Diodes may be included in the base leads of transistors 53, 54, 60 (Fig. 5, not shown) to provide a threshold to eliminate false actuation by noise. The circuit can be adapted for negative input signals. In a NAND circuit (Fig. 6) the inputs are applied via diodes 77, 78 to the base of a transistor 92 so that the potential at 82 will turn on transistor 92 only if all the positive input signals are present. Only if this is the case will transistor 85 be turned on to allow transistor 86 to pass current from the supply to transistor 92 and thus bring it into a low-impedance state to energize similar circuits joined to its collector. As in Fig. 5 (not shown), diodes 90 and 93 provide a threshold level for the input signals. The diodes 77, 78 may be replaced by a multiemitter transistor (Fig. 7, not shown). Alternatively (Fig. 8, not shown), transistor 85 and diode 90 may be replaced by a diode (123) connected between the base of a transistor (114 corresponding to 86) and the collector of transistor (113 corresponding to 92), thus controlling the output current directly. Fig. 9 (not shown) describes a fast-acting NAND circuit driving a plurality of output circuits represented by a capacitor (147). If all the inputs are positive, cutting off diodes (143, 144), all four transistors will be on, and capacitor (135) will be charged through low resistor (133), giving a " low " output. If one of the inputs drops, transistors (140) and (132) will be cut off, and all the current through resistor (129) will be diverted through (128), turning on transistor (131) rapidly to give a large pulse of current through the output, aided by the discharge of capacitor (135), which is however optional. When the output capacitor has charged up, transistors (128 and 131) cut off and no power is consumed until the input signals change once more.
