Abstract: 545,901. Developing photographic films. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). May 24, 1940, No. 9200. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1940.] [Class 98 (ii)] A film, e.g. of regenerated cellulose or of superficially-saponified acetyl cellulose, liable to deformation when wetted, is wound for development &c. in a single layer on a support having an invariable diameter and provided with a helical rib for separating the turns, and forces are exerted upon the film having a component directed towards the axis of the support to maintain the film thereon and prevent relative movement during treatment. The support may be a drum 1, having a helical rib 5 forming a track for the film 2, and rotatable in a shallow dish of arcuate section or in a cylinder which completely encloses the drum. The film may be wound on the drum under tension sufficient to ensure that it will still remain taut if it expands when wetted, and be held by end-clips at 6, 7 ; or it may be maintained on the drum by suction applied through holes in the drum from a duct in the drum-shaft. The developer may be a physical developer, e.g. metol, tartaric acid, and silver nitrate, whose quantity and composition are correlated to the area of film to be developed and the desired density of image. The material physically developed may be an exposed diazotype. Reference is made to Specification 512,527.

Title: Measuring and Recording Apparatus intended to be Connected to the Contact of a Conventional Movement Detector for Drilling Apparatus
IPC: G04F10/10
Filed: 1968-02-27
Abstract: 1,182,387. Recording-apparatus. GEOSERVICES. Feb. 27, 1968 [March 14, 1967], No.9438/68. Heading G1J. The depth of penetration of a drilling tool is recorded against elapsed time by apparatus, connected to the switch 11 of a movement detector and including electrically controlled pen-drive, and chart-drive mechanisms, by causing the chart to advance a unit distance each time the switch is actuated, generating a variable e.g. a voltage, proportional to the elapsed time from the last actuation of the switch and transmitting the instantaneous voltage to the pen-drive control on each occasion the switch is actuated. Chart-drive. Once in every revolution of a pulley over which the drill cable runs, a cam actuates the switch 11 to operate a relay 28, Fig.5, which makes its holding circuit and starts a motor 23 through switches 26, 27. The motor 23 drives the shaft 19 of a roller round which the chart is drawn and, in turning a toothed wheel 20, lifts a feeler 22 to actuate a switch 21 which releases the relay 28 and holds the circuit of the motor 23 until the feeler 22 falls into the next tooth space. Between successive actuations of the switch 11 a variable representing elapsed time is stored and its final value is transmitted to the pen-drive mechanism to be plotted on the chart before being erased. The timing may be done by a capacitor charged from a direct current source, connected to the pen mechanism through a resistance and discharged under control of a switch 37, Fig. 6 (not shown) and Fig. 15. Alternatively a clock or synchronous motor is used to drive the wiper of an annular potentiometer, Fig. 7 (not shown) or to drive a pen carrier when a clutch is engaged, Fig.8 (not shown). The control circuit, Fig.15, is connected through a rectifier 62 to the terminals 60, 61 of the chart-drive motor 23 for energization therewith. Operation of a relay 63, delayed by a capacitor 64, reverses switches 66 and 45: the latter, to operate the pen-drive and so to record the stored value representing elapsed time; the former to erase the stored value when the contacts 37 are operated by a relay 38 after capacitor 68 has discharged through resistance 69. The control circuit of a servomotor for driving the pen is described with reference to Fig. 10 (not shown) and Figs.9, 11 (not shown) illustrate a timing circuit and pen control circuit for recording elapsed time during interruptions for drill manoeuvres.

Title: Improvements in fluid control for internal combustion engines
IPC: F02M1/00
Filed: 1920-04-06
Abstract: 167,807. Pokorny, F. April 6, 1920. Fluids, regulating volume of flow of. - The cross - sectional area for the flow of mixture from the carburettor throttle of an internal - combustion engine to the intake manifold is automatically increased with the increase of engine suction by means of a gravity-returned valve, which is arranged to be slowly lifted during the first stages of increase of engine suction, and to be lifted more rapidly after a predetermined suction has been reached. Fig. 1 shows a casing 5 inserted between the throttle 6 and the intake manifold 2, and carrying therein a fixed nozzle 15 providing the normal passage for the mixture. A tubular valve 20 surrounds the nozzle and has a downward extension 20<a> working between fixed sleeves 10, 21, the upper part 23 of the valve co-operating with a sleeve 24. When the engine is running slowly, the valve, 20, as shown, closes the passage surrounding the nozzle 15. When the suction increases, the vacuum produced in the chamber x exerts a lifting-force on the valve, which, however, is opposed by the lesser action of the vacuum produced below the end of the extension 20<a>, so that the valve rises slowly and allows additional mixture to pass around the nozzle 15. The clearance between the upper part 23 of the valve and the sleeve 24 increases as the valve rises, thereby increasing the vacuum in the chamber x, and, consequently, the lift on the valve. In a modification, the extension 20a is provided with an internal flange at its lower end, the space between the sleeves 10, 21 being increased to receive this flange.

Patent GB-721484-A (GB)
Title: Improvements in or relating to the degradation of dextran
IPC: C12P19/14
Filed: 1952-04-17
Abstract: An aminoacid-stimulated dextran-acclimated enzyme which degrades dextran in an aqueous medium (see Group V), is obtained by cultivating an Aspergillus mould, e.g. a strain of Aspergillus Wentii in a nutrient solution containing dextran (see Group VI). The enzyme may be separated from the culture medium by filtration and precipitated from the filtrate by adding acetone or dioxane. Alternatively, the enzyme may be salted out by adding ammonium sulphate, sodium sulphate or sodium chloride to the filtrate.  The precipitate may be dried to yield a powder.ALSO:In making dextran of low molecular weight from dextran of relatively high molecular weight, an aminoacid-stimulated, dextran-acclimated enzyme from an Aspergillus mould, e.g. a strain of Aspergillus Wentii (see Groups IV(b) and VI) is mixed with dextran of high molecular weight in an aqueous medium, the mixture is kept until the desired degree of degradation is attained and dextran of low molecular weight is removed, e.g. precipitated by adding to the degraded mixture an organic precipitant such as alcohol.  The degraded mixture may first be separated into layers by adding acetone and a degraded dextran fraction may then be precipitated from each layer.  The precipitate may be dissolved in water and reprecipitated.  The precipitates may be dried in vacuo.  The action of the enzyme may be stopped by bringing the pH of the mixture into the range of about 2.0 to 3.0 or 9.0 to 10.0, e.g. when the viscosity of the mixture relative to water is 2.0.  The enzyme may be added to a medium containing about 7 per cent. of dextran.ALSO:An Aspergillus mould, e.g. a strain of Aspergillus Wentii is cultivated in an aqueous nutrient solution containing dextran, e.g., from 5.0 to 50 g dextran per litre, and a source of aminoacids so that a dextran-acclimated, aminoacid-stimulated enzyme (see Group IV(b)) is produced.  This enzyme is used to degrade dextran (see Group V).  The nutrient solution may contain the following substances in g. per litre; peptone 5.0, dextran 10.0, magnesium sulphate 0.1, sodium chloride 0.1, ferrous sulphate 0.1, sodium chloride 0.1, ferrous sulphate 0.01, manganous sulphate 0.01, potassium dihydrogen phosphate 0.1, sodium acetate 2.0, potassium acetate 0.5, with or without the following vitamins in m.g. per litre :-nicotinic acid 1.0, riboflavin 0.5, thiamine 0.5, calcium pantothenate 0.5, pyridoxine 0.4, folic acid 0.01, biotin 0.001.  The peptone may be replaced by 5.0 g casein hydrolysate per litre.  The vitamins may be replaced by 0.4 g. yeast extract per litre.

Title: Improvements in surgical trusses
IPC: A61F5/26
Filed: 1924-04-17
Abstract: 225,117. Schutze, F. April 17, 1924. Addition to 216,445. Trusses.-In surgical trusses in which, as described in the parent Specification, the pad is connected to the main portion of the belt by means including one or more coiled springs, a plurality of springs or sets of springs is provided which are adapted to be brought into action successively as the belt is tightened. The belt 1, as described in the parent Specification, is connected to the pad 3 at one side by a stud or button 4 and at the other side by a strap 10 connected to a fabric loop 11 between which and a loop 14 connected to the back portion 2 the springs are arranged, the belt being made in the form of an open-ended sheath to permit the proper working of the springs. As shown in Fig. 3, three springs 15 - - 17 are provided, of which the middle spring 16 is directly connected to the plates 12, 13 attached to the loops 11, 14 respectively. The springs 15, 17 are directly joined to one of the plates but are joined to the other by means of chains or like flexible connections 18, 19, the chain 18 being the longer. By means of the buckle 21 the belt can be adjusted so that the spring 16 alone, the springs 16, 17, or all three springs, are operative. The number of springs may be varied, a set of two or more springs, for example, being used to give the initial tension and other springs or sets of springs being arranged to be brought successively into play. A modified construction is described in which the chains 18, 19 are replaced bv headed rods of different lengths which are drawn through the springs as the belt is tightened until the heads engage end abutments on the springs and cause them to extend. Fig. 7 shows another construction in which compression springs are used. The bar 12 slides on the wires 25 as the belt is tightened and brings the springs, which are of different lengths, successively into play. Fig. 9 shows a further modification in which two sets of springs 26, 27 are connected in series, the set 27 being the stronger. The springs 26 are operative until the belt is tightened sufficiently to extend the check chains 28, after which the springs 27 come into action. Both sides of the belt may contain springs instead of one side only.
