Patent GB-1241287-A (GB)
Title: System for marking of objects, in particular fuel elements in nuclear reactors
Inventor: CRUTZEN SERGE
IPC: G21C3/16
Filed: 1970-07-09
Abstract: 1,241,287. Fuel elements. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 9 July, 1970 [10 July, 1969], No. 33458/70. Heading G6C. In a system for marking fuel elements by means of a plurality of marks in random configuration with scanning means for the location of such marks, the marks comprise inclusions of foreign matter disposed below the surface of the element in a zone which is defined or can be determined from the exterior. Small tungsten balls may be used for fuel elements encased in steel, which balls are located from the exterior by ultrasonic or magnetic scanning means. In the case of MTR fuel elements of slightly curved plate form, the marking is applied to the non-active edge zone of one narrow side and the scanning apparatus locates the inclusions along the edge as well as in a direction at right angles to the edge. In one example, before the casing around the fuel is closed a number of small balls are scattered on the flat internal surface in the edge zone of one casing side. A genuine random distribution is obtained by shaking of the base. Subsequently, a stamp, the external dimensions of which correspond to the scanning zone, impresses the balls into the base. The remaining balls are blown away after which the fuel element is closed. In rod-shaped fuel elements the scanning zone will be preferably disposed on the upper end which is free of fissile material and along a circumferential line near the edge or along a surface line. In this case, the marks are also impressed into the inside of the casing during manufacture.

An electrical connector comprises a sleeve 6 fitted over and extending from one end of a conductor-receiving ferrule 4, the sleeve having an inwardly extending, double-walled, annular projection 10 which inclines towards, and acts to locate, the ferrule. The projection is formed by a fold in the sleeve and serves as a funnel to guide the conductor into its place in the connector, and acts as a stop to the insulation on the conductor. The internal surface of the ferrule has serrations 7. The sleeve may be plated, and is covered with a further insulating sleeve 8. When the conductor is in position the connector is crimped on to it and on to its insulation. In an alternative embodiment (Fig. 4, not shown), the portion of the sleeve extending from the ferrule is of much greater diameter than the portion on the ferrule, so that conductors having a thick layer of insulation may be accommodated. The annular projection is formed by a spinning operation during manufacture of the sleeve, and has an inclination of preferably 30 degrees to the axis of the sleeve. The connector may be formed as a splice to interconnect two wires.

Abstract: 810,309. Boring &c. machine details. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Nov. 25, 1955 [Dec. 8, 1954], No. 33805/55. Class 83 (3). [Also in Group XXIX] In a boring &c. machine wherein a verticallyadjustable beam 9 supported near each end by a piston 14, 15 and along which a tool-carrying headstock 12 is movable horizontally, means h1, h2, 36, 36 are provided for adjusting the pressure beneath the pistons in accordance with the position of the headstock. The pistons are supported in cylinders 16, 17 fed with oil from continuously-rotary pumps a, d, further pumps b, c delivering oil beneath the pistons only when the beam is raised, under the control of screws 24 rotatable in nuts 26 in the beam, by an electric motor (not shown). The pressure in the cylinders is adjusted through valves h1, h2 which are subjected to a variable-pressure from circuits V1, V2 controlled by the headstock, the valves controlling the escape of pressure between the pumps a, d and cylinders and hence the pressure in the cylinders. A further, highpressure, pump e supplies oil through a line t to a pair of valves 36, Fig. 3, on the beam, connected in parallel, and each controlling the pressure in one of the circuits V1, V2 respectively. Each valve is pressed against its adjustable operating-lever 33 by a spring 38, and has diagonally-opposite chamfers 44, 45 which afford a lead into the associated circuit V1 or V2 and out to exhaust, the latter through one of the ports 39 in the valve-housing 37, which are interconnected by an annular channel in the bore of the housing, and through a return-pipe 46 in the valve-box 27. The operating lever 33 is pressed against a follower 20, and the latter against one of a pair of oppositely-inclined plate-cams 22 on the headstock 12, by a plunger 35. Adjustment of the headstock towards the left-hand end of the beam causes the follower 20 for piston 16 to rise and the associated valve 36 to fall, thus increasing the valve-opening 39 to circuit V1 and reducing the valve openings at 45 and h1 to exhaust. A corresponding, opposite movement of valve h2 occurs, reducing the pressure in cylinder 17. Free barrier-pistons in cylinders m1, m2 prevent the transmission of heat between the oil passing through the pumps and that in cylinders 16, 17, valves in the pistons opening, to compensate for loss of oil, when the pistons reach the ends of the cylinders. The beam of a single-column, horizontal boring-machine (Fig. 4, not shown), may be balanced in the same manner.

Title: Improvements in process for the production of penicillin
IPC: C07D499/00
Filed: 1946-11-14
Abstract: A penicillin which forms a crystallizable salt with a symmetrical trialkylamine selected from trimethylamine, triethylamine, tri-n-propylamine and tri-isopropylamine is recovered and purified by adding the trialkylamine to a solution of the crude penicillin in a solvent which has selective solvent properties for the trialkylamine salt of the penicillin, and subsequently crystallizing and separating the trialkylamine salt of the penicillin from the resulting solution. In the preferred embodiment of the invention, a substantially anhydrous solution of penicillin is made in ether, methyl isobutyl ketone, amyl acetate or methylamyl acetate (or, less satisfactorily, 1 : 4-dioxane or n-butyl alcohol), sufficient trialkylamine (especially triethylamine) is added to precipitate the impurities, which are filtered off, and a further quantity of trialkylamine is added to cause crystallization of the trialkylamine salt of the penicillin.  Alternatively, excess of triethylamine is added to a solution of crude penicillin in a mixture of ether and aqueous acetone until the solution is alkaline, when it is diluted with ether until cloudiness is barely perceptible and the triethylamine salt of the penicillin is crystallized out while maintaining the impurities in solution. The process is particularly applicable to the purification of penicillin G, the starting material being preferably obtained from the filtered culture medium by acidifying it to about pH 2, extracting it with anyl acetate, extracting the amyl acetate with water buffered with disodium phosphate until the combined extracts have a pH about 7, acidifying them to about pH 2, extracting with chloroform, extracting the chloroform solution with alkali to about pH 7, and extracting the aqueous solution with ether with the addition of acid to about pH 2.  The triethylamine salt of penicillin G may be converted to other salts, such as the sodium salt (e.g. by acidifying an aqueous solution of the triethylamine salt, extracting with a water-immiscible solvent, extracting the resulting solution with aqueous caustic soda to about pH 6.8 and freeze-drying), or the calcium or potassium salt.  Examples illustrate the various features of the invention.

Title: Improvements in or relating to electrical current and voltage regulation devices
IPC: H02J7/16
Filed: 1956-11-08
Abstract: 815,635. Automatic voltage-control systems. GENERAL MOTORS CORPORATION. Nov. 8, 1956 [Nov. 14, 1955], No. 34135/56. Class 38(4). The field current of a self-excited D.C. generator (for use on a motor vehicle) is controlled by connecting the field in series with a transistor which is itself controlled in dependence on the output voltage and current of the generator. In one embodiment, Fig. 1, the generator 20 supplies a battery through a rectifier 36 (or a conventional cut-out). The field 22 is connected across the generator in series with a transistor 30. When the output voltage tapped off a potential divider 34 exceeds the breakdown voltage of a Zener diode 74 the resulting reduction in the base potential of a common emitter amplifier transistor 62 reduces the current through the transistor 30 via the emitter follower transistor 48. The load current through resistor 32 controls a two-stage transistor amplifier 102, 92, the point 84 becoming less positive as the load current increases until a Zener diode 82 breaks down and the current is controlled by transistor 62 as above. In a second embodiment, Fig. 2, the field 22 is controlled by a unipolar transistor 112, the junction gate of which is subject to the generator output voltage plus the voltage drop across resistor 132 carrying the load current, when the Zener diode 122 breaks down. The voltage across resistor 132 is also amplified by transistors 128, 130 and applied to the Zener diode 126 to provide current control above the valve at which the diode 126 breaks down. In a third embodiment, Fig. 3 (hot shown), the unipolar transistor is replaced by a junction transistor directly coupled to a transistor amplifier sensitive to output voltage and current derived as in Fig. 2. Specification 787,160 is referred to.

Abstract: 325,549. Pollak, J. E., (Associated Telephone & Telegraph Co.).. Nov. 21, 1928. Coin-freed apparatus; impulse transmitters for automatic exchange systems. - Urgent calls, such as ambulance, police and fire calls, are allotted numbers having less than the full number of digits, and may be completed without the deposit of any coins, an attachment being made to the dial by which the impulse-springs are short-circuited after a predetermined number of digits unless a suitable coin has been deposited in order to prevent the fraudulent setting up of calls which need to be paid for. The arrangement is also applicable to a system in which a subscriber may set up freely only local calls, other calls requiring a greater number of digits being completed with the help of an operator. The arm 1, which normally operates the shunt springs, for each digit dialled advances a ratchet member 8 one step by means of a pawl 7 on the end of a bent lever 2. After a predetermined number of digits, the ratchet member 8 operates contact springs 13 which shunt the impulse-springs. The initial position of the ratchet member is determined by a stop 11 on a member 15 which may be adjusted as required, and locked by a screw 17 passing through a slot 16. In Fig. 2, the springs CS are controlled by the coin shoot, and the springs DS are those controlled by the dial. If no coin is deposited, the instruments are in condition for conversation, and the dial is effective only for the number of digits necessary for an urgent call. If a coin is deposited, the springs CS are operated, and the instruments are put out of action, but the shunt applied across the impulse-springs at the springs DS is rendered ineffective; the springs CS are restored by depression of the cashing-in button. Replacing of the receiver restores the springs. DS. Alternatively, the insertion of a coin may raise the holding pawl to render the ratchet mechanism ineffective. It may also be aranged that the ratchet mechanism is ineffective if certain digits are dialled. Specifications 234,036 and 316,261 are referred to.
