Abstract: 179,527. Bonnet, L. May 3, 1921, [Convention date]. Beads, making.-Imitation pearls in glass or enamel are formed on a solid metal wire provided with a thin coating of friable and refractory material, such as a mixture of alumina and kaolin in equal parts, to prevent the fused material from adhering to the wire. The pearls are removed by being slid along the wire. The wire 1 is held at one end in a chuck 6 on a rotary shaft 5, the other end being hooked at 8 to a rod 7 provided with a spring 9 acting between a nut 10 and a vertical support 4 to tension the wire. Intermediate vertical supports 11 with top grooves are provided on the table 3 which also carries a ramp or rest 13 for the hands of the operator, who holds a blowpipe and a rod 14 of glass or enamel. The shaft 5 is rotated by a motor and driving-gear having speed-regulating means. The alumina and kaolin worked to a paste in water is applied with a spatula to the wire

Abstract: 1459822 Automatic control of clay plasticity MANFRED LEISENBERG KG INDUSTRIEFEUERUNGEN 14 March 1974 [26 May 1973] 11314/74 Heading G3R In a system for controlling the water content of clay passing from a mixer 5 to an extruder 7 by the metered addition of water or steam, or dry substance(s) if the clay is too moist, the power input to the mixer drive motor 6 is measured and a corresponding signal 25 fed to a comparator 26 along with a reference signal 27 to give an error signal 28, 30 which is used to control a dosing device 31 in a pipe-line 34 to the mixer, and the plasticity of the clay 3 in or leaving the extruder is also measured and compared with a further reference signal 19, a resultant error signal 20, 22 being used to adjust the reference signal 27 fed to the first comparator 26. Dosing device 31 comprises a D.C. pulse converter 32 controlling an electromagnetic valve 33 or alternatively a D.C. motor (35) Fig. 3 (not shown), actuating a metering device. The power measurement is performed by a C.T. 23 and an A.C.-D.C. converter 24. The respective error signals 20, 28 are passed through an integrator 21 and a proportional controller 29. Each of the latter comprises an operational amplifier (41) Fig. 2 (not shown) with a parallel RC feedback circuit to give a response with a long time constant. During a production stoppage, relays (44) open-circuit the capacitors so that they retain their stored charge until start-up. To prevent overswing on start-up, a feedback capacitor (47) in the integrating section of device 21 is also opencircuited by a further relay (48) during a stoppage.

Title: Improvements in and relating to self-driving hydraulic installations
IPC: F03G7/10
Filed: 1931-04-17
Abstract: 371,597. Self-driving hydraulic machines. BROWN, J., 4414, Chesapeake Street, Northwest, Washington, U.S.A. April 17, 1931, No. 11435. [Class 10.] In a self-driving hydraulic prime-mover, fluid pressure produced by a plunger 4 is transmitted to the spaces 7, 7<1> of two cylinders containing pistons 8, 8<1> each formed with an annular and a circular end working in correspondingly formed spaces in the cylinder and so designed that the spaces 7, 7<1> do not alter in volume as the piston moves. The pistons are stated to move downwards under the pressure in the spaces 7, 7<1>, and the piston heads 10 form the plungers of two pumps which deliver to a Pelton wheel 15, the water from which passes back to the pumps in a closed circuit. Valves actuated by the pistons connect each space 7, 7<1> to the pressure pipe 5 on the downstroke, and cut off the connection on the upstroke, of the respective piston. Each piston carries a pair of vertical plungers 19 operating in connected vertical bores 20, containing an incompressible fluid, the two pistons being thus constrained to work in opposite phase. The apparatus shown is intended to be operated by a head of water acting on the underface of a member 1 connected by a lever 3 to the plunger 4, which thus places the fluid in the pipe 5 under pressure. A modification comprises opposed cylinders mechanically coupled.

Title: Penicillins
IPC: C07D499/42
Filed: 1968-03-08
Abstract: 1,212,551. Penicillins. ANKERFARM S.p.A. 8 March, 1968 [8 March, 1967], No. 11530/68. Heading C2A. A semi-synthetic penicillin is produced by the acylatiqn of 6 - aminopenicillanic acid adsorbed on an anion exchange resin e.g. Amberlite (Registered Trade Mark) IRA-401. The 6-APA is obtained by the enzymatic hydrolysis of a penicillin such as benzyl penicillin. Preferably the penicillin acylase is derived from a micro-organism resistant to high concentrations of the acyl moiety of the starting penicillin, e.g. phenylacetic acid or phenoxyacetic acid. Thus, in the case of benzylpenicillin, the micro-organism may be a mutant of E. coli Ankerfarm Sp. 27/14 (CBS 128À67) cultured serially on media containing increasing concentrations of phenylacetic acid or phenoxyacetic acid. The hydrolysis of the penicillin may be carried out with cultures or enzyme extracts of the micro-organisms. After hydrolysis, impurities may be removed by extraction with a water-immiscible solvent, e.g. ether, and the aqueous phase containing the 6- APA treated with the resin at pH 6À0. The 6-APA resinate is separated from the solvent, washed to remove impurities and then suspended in water of pH 7 to 9 containing sodium chloride. The acylating agent is used as the chloride or anhydride, which is dissolved in a watermiscible solvent such as acetone and added to the aqueous suspension of 6-APA resinate at e.g. 0‹ C. After acidifying to e.g. pH 2À0, the result ant penicillin may be extracted with a waterimmiscible solvent e.g. ethyl acetate. The penicillin may be recovered as a salt by extracting the organic solution thereof with an aqueous solution of a base, e.g. sodium bicarbonate solution.

Class 110(1) To protect the user of a vacuum cleaner from electrical shock, the impeller, which can be touched by the user when the suction nozzle is removed from the suction aperture of the vacuum cleaner housing, is electrically insulated from the driving shaft by a cap of insulating material which at the same time covers the free end end of the shaft. In one embodiment, Fig. 2, the metal impeller 6 is insulated from the driving motor shaft 5 by a rubber cap 8. A flange 8<SP>1</SP> of the cap separates the impeller hub 9 from an adjacent shoulder of the shaft. In the embodiment shown in Fig. 3, the insulation is in the form of a rubber coating 10 which is advantageously sprayed on to the impeller. The rubber coating protects the impeller blades 7 from damage by metal objects drawn in by the vacuum cleaner, and reduces noise. In an alternative construction, the impeller blades are of rubber and are integral with the rubber coating 10.

Title: Improvements in or relating to moderator structures for heterogeneous nuclear reactors

IPC: G21C5/04
Filed: 1966-03-17
Abstract: 1,090,587. Moderator structures. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 17, 1966 [March 17, 1965], No. 11689/66. Heading G6C. A solid moderator, e.g. graphite, bar is formed with at least one helical slot which is cut in a lateral surface of the bar. Where the bar includes a bore, the outside surface and/or the inside surface can be formed with helical slots. Preferably, slots are formed in both the outside and the inside surfaces and are of the same pitch and hand. From the point of view of bar strength, the outer slots should be offset from the inner slots. The slots should be very narrow in order to limit loss of moderator material. The region of the cross-section of the bar in which the stresses due to the Wigner effect have not been interrupted is reduced by this means to that between two cylinders of revolution on which the bases of the outer and inner slots lie. Alternatively, the outer slots may be of the same pitch as the inner slots but of opposite hand, or the slots in any one surface may be in the form of two series of helices which have the same pitch and opposite hands. In zones where axial or circumferential stresses are severe, the outer or inner slots can have veryshort-pitch or very-long-pitch slots, respectively, superimposed on them.
