Title: Improvements in or relating to roughcast surfaces for building purposes, and to glass fragments suitable for incorporation therein
IPC: E04F13/02
Filed: 1936-09-24
Abstract: Glass fragments suitable for incorporation in rough-cast surfaces are prepared by subjecting glass, which has been formed in the molten state and allowed to cool in a receptacle, to a subsequent heat treatment at a temperature in the neighbourhood of the softening point of the glass, followed by slow cooling at somewhat the same rate as for plate glass or heavy roofing glass, and comminution.  In the comminution process, the glass is first fed from above between a pair of rocking jaws which are pivoted at their lower ends and are spaced apart so as to leave a small gap at their lower ends and a larger gap at their upper ends; the jaws are provided with flutes running from top to bottom of the jaws. The crushed glass is then further crushed between adjustable rollers which are provided on their surfaces with rounded ribs extending parallel, or substantially parallel, to the axes of the rollers.

Title: Method of cleaning the contact members and other metal parts in electric switches operating in evacuated containers
IPC: H01H33/66
Filed: 1931-09-17
Abstract: 390,151. Switch contacts. BIRKA REGULATOR GES., 40, Konigstrasse, Wannsee, and ROZUMEK, E., 10, Marsschnerstrasse, Lichterfelde, both in Berlin. Sept. 17, 1931, No. 26096. Convention date, Sept. 17, 1930. [Class 38 (v).] The contacts of switches in evacuated containers are cleaned and freed from impurities during the evacuation of the container by being included in a circuit of relatively low voltage containing an inductance and carrying a current of the same order of magnitude as the normal working current so that a discharge from the inductance occurs repeatedly across the contacts and produces a series of sparks therebetween. As shown in the Figure, a number of thermal switches in containers 1 are disposed within an evacuating stove 4 and have their contact members 2 connected to a low voltage battery 6 in a circuit containing a large inductance 5. The thermal elements 3 are connected to brushes bearing on a rotary drum 7, the drum contact also passing to a control circuit 9, and as each brush 8 is engaged by the contact, the corresponding thermal element closes the switch contacts. Thus the opening of the contacts in turn by the thermal element as the drum contact leaves the brushes causes the discharge of the inductance to pass across the contacts 2 in turn and remove impurities, oxides, &c., therefrom during the evacuating process. In a modified arrangement, Fig. 2 (not shown), the contacts of the treated switches are arranged to be separated by a small gap across which the discharge of the inductance is arranged to be produced by an auxiliary thermal switch the switching movements of which are controlled by a drum switch in a manner similar to that already described in connection with the Figure. The battery 6 may be replaced by any other suitable source of current.

Title: Derivatives of cephalosporin c
Inventor: ABRAHAM EDWARD PENLEY
IPC: C07D501/38
Filed: 1959-08-04
Abstract: The nucleus of Cephalosporin C, Cephalosporin Cc or a Cephalosporin Ca compound is prepared by treating Cephalosporin C, Cephalosporin Cc or a Cephalosporin Ca compound, such as Cephalosporin Ca (pyridine), or a derivative of any of these compounds in which the amino group of the amino-adipoyl sidechain is blocked by a grouping which is not detached therefrom during the hydrolysis and which hinders Zwitterion formation in the sidechain, with acid under such conditions and for such a time that cleavage of the sidechain or blocked sidechain from the nucleus occurs to form the corresponding nucleus and separating the nucleus so formed from the reaction products.  The blocking group may be 2,4-dinitrophenyl or 2-nitro-4-carbomethoxyphenyl and the preferred acid is hydrochloric acid.  Other acids which may be used include sulphonic acids and sulphonated polystyrene resins.  The nucleus may be separated from the reaction products by electrophoresis, chromatography or ion exchange. The nucleus of Cephalosporin C forms salts, such as sodium, potassium and ammonium salts, on bases, and all three types of nuclei form acid addition salts at the primary amino group. The nuclei may be used in the production of new Cephalosporins by acylation of the 7-amino group. Specifications 810,196, 912,360 and 912,541 also are referred to.

Title: Improvements in or relating to ship stabilizer systems
Inventor: MUIRHEAD FRANCIS HERON
IPC: B63B39/06
Filed: 1959-08-04
Abstract: 873,378. Stabilizing strips. MUIRHEAD & CO. Ltd. Dec. 1, 1959 [Aug. 4, 1959 ; Aug. 6, 1959], Nos. 26580/59 and 26947/59. Class 113. A stabilizer system comprises fins spaced along the hull in the region of the bilge for oscillation about a neutral position by means of hydraulic motors, pump means, pipe lines for circulating fluid from the pump through said motors, valve means for controlling the fluid flow to the motors, sensing means mounted to respond to roll of the hull and means for operating the valve means from the roll sensing means. Each fin 2, Fig. 1a, is made from an elastomer and is rotatably supported on a shaft 1 rigidly attached to the ship structure 3, the unsupported and non-reinforced outer port X-X<SP>1</SP> being sufficiently rigid to withstand the normal forces of lift and drag but yieldable to abnormal forces. As a safety device the fin shaft may have a section of reduced diameter to permit the fins breaking off on impact with a solid object. In Fig. 4 pump 59 delivers hydraulic fluid to units 35<SP>1</SP>, 35<SP>11</SP> housing the valves in pipe lines 67 to one side of the appropriate motor actuating a fin 2 and pipe lines 68 to the other side. The valves are operated in sequence by a tilting arm 51 connected to the roll sensing device 50. Pipe lines 62 extend from the pump to a bolt actuating cylinder associated with each fin to hold same in neutral position when not required for active stabilising, the fins then acting as bilge keels. Sea water may be used as the hydraulic fluid. The number of fins in operation may be reduced with increased ship speed. In Fig. 8 the roll sensing device 50 operates tilting arm 51 via a slotted lever 71 in which a fulcrum 73 slides under the control of a device 69 sensitive to ship speed. The fin actuating motors are of the rotary vane type, but as shown in Fig. 10, a jack type may be employed. A cylinder block attached to the fin has plungers 86, 87 abutting a thrust block 88 integral with the fin pintle 89. The valves controlling supply of fluid to the cylinders are actuated by push rods 75 in contact with the face 74a, b, c of a cam 74 carried on shaft 50a. Another set of push rods actuate the valves of the motors on the other side of the ship to move the fins in the opposite direction.

Abstract: 1,045,376. Cleaning tubes. S. A. CHRISTENSEN & CO. A.S. June 25, 1965 [June 27, 1964], No. 2704G/65. Heading F2N. [Also in Division A1] A device for cleansing milking equipment 1 and pipe lines 2 comprises a vessel 8 of cleansing fluid, a tank 4 mounted for vertical movement above the vessel and connected by a multiway valve 10 to a vacuum pump, the bottom of the tank 4 communicating through a pipe connection 5, 7 and a suction or vacuum closure 6 with the vessel 8 and the top of the tank 4 communicating with the vessel 8 through the pipe 2 and the equipment 1 whereby on operation of the pump cleaning fluid circulates from the vessel 8 through the equipment, the pipe, the tank and back to the vessel 8. The closure 6 comprises a thin, flexible rubber tube which tends to close due to external pressure when the vessel 4 is under suction or a ball-valve (Fig. 3, not shown) which acts similarly. The tank 4 is supported in rings 13a and 13b on a two-armed lever 14 pivoted at 15 and having a counterweight 16 sufficient to raise the tank in the rings 13a and 13b when it is empty. In this position the valve 10 connects the tank to the vacuum pump, causing the closure 6 to close and sucking up cleansing fluid through the pipe 2 until it reaches a predetermined level in the tank where the counterweight 16 is outbalanced. The frame 13 and tank 4 then fall and a projection 12 on the lever 14 which hits in an extension 11 on the valve control, causing the valve 10 to disconnect the interior of the tank from the pump and to connect it to atmosphere. As the pressure in the tank 4 rises again the closure 6 opens and the cleansing fluid in the tank flows back into the vessel 8. If only one washing cycle is desired it may be arranged for a time switch to cut off the vacuum pump when the tank 4 falls again; alternatively, the washing sequence may be repeated and the pump cut off , by a time switch (not shown).
