Abstract: 798,995. Towing ships &c. McKERNANTERRY CORPORATION. Dec. 19, 1956, No. 38724/56. Class 14. A boom structure adapted to be mounted on a ship for towing vessels comprises a parallelogram arrangement of booms 16, 17 in superposed relationship with their outer ends connected by a head 18 and their inner ends pivoted at 14, 15 to a framework on a base 10 which also supports a drum 11 connected by an articulated cable 13 through a conical guide 22 to a vessel 24 to be towed. The drum surface is hexagonal to conform to the articulations of the cable 13 which passes over hexagonal sheaves 12, 21, the latter being mounted on the pivot 20 connecting the lower boom 17 to the head 18 so as to bring the cable 13 directly above the apex of the conical guide 22. The vessel 24 is held in the guide 22 by pivoted latches 37, Fig. 9, which engage stops 39 secured to the cable, the latches being retractible hydraulically when pressure liquid is admitted to the inner ends of cylinders 40. The booms 16, 17 form one side of a pair of struts arranged as a V and pivoted to the framework at their open base ends to permit the guide 22 and vessel 24 to be stowed between them in the inboard position to which they are drawn by the cable 13 when, in its hoisting movement, it has housed the vessel 24 in the guide 22. The drum is traversed to ensure a straight pull on the articulated cable 13. When the sheave 21 passes an upper dead centre position as it approaches the inboard, stowage position, a lost motion connection between the boom 17 and a lever 47 is taken up and the lever compresses an hydraulic cushion 45 as the mechanism approaches that position which is determined by a.resilient pad 36 on the boom engaging a stop 34 on the framework. In its outward, operative position, the boom is locked by hydraulically actuated pins 43 passing through an extension 41 of the boom 17 and a bracket 42 on the head 18 and engaged by the extension 41.

Abstract: 963,396. Correcting inductive disturbances. FERNSEH G.m.b.H. Nov. 17, 1960 [Nov. 17, 1959], No. 39472/60. Heading H4R. In an arrangement for minimizing earth current disturbances, an H.F. signal incoming over the inner conductor a coaxial cable 19 is applied between the control grid and cathode of a high impedance valve 1, the cathode being connected directly to the outer conductor of the cable and also to earth over a resistance 12, the output signal being taken from between the anode of the valve and earth. By this means the signal voltage only is applied to the valve, the earth current voltage being developed only across the resistance 12, so that it makes only a small contribution to the output as compared with the amplified signal. In a modification, Fig. 3, the resistor 12 is split into portions 12a 12b, so dimensioned that the voltage developed over 12a, which is applied to the grid cathode circuit of the valve, after amplification cancels out that developed over the portion 12b.

Abstract: 339,518. Moulet, J. L. L. A. A. Dec. 27, 1929. Diaphragm and flexible-chamber pumps; actuating by electromagnets and springs; regulating delivery by varying speed of motor.-The suction stroke of a diaphragm bellows or other pump 2 is effected by motion of the core or armature 6 of an electromagnet connected to the pump; the switch controlling the current comprises a lever 18 having a projection co-operating with a projection on a spring 15 mounted on the movable core. The discharge stroke is effected by the elasticity of the bellows &c. 2. The pump body, the casing 8 of the solenoid and the casing 80 of the lever are held together by a strap 28 pivoted on the pump body and carrying a set screw 29. Leakage is prevented by packing. Lubrication is effected through an oil cup 101, a duct 100 in the upper plate 11 of the solenoid casing, a groove containing a wick, and holes in the tube 10 surrounding the core 6 by which the oil is delivered to the core surface, afterwards flowing through a passage 104 in the stationary armature 71 to a recess in the lever 18, ducts in which convey oil to the pivot pin and the bevelled end; surplus oil escapes by an aperture 109 in the lever casing. Oil is used which flows only when warmed by the motion of the parts. The admission valve casing contains a filter 64 surrounding a tube 67 by which liquid is conveyed to the valve 33; an air cushion is left in the space 68 around the top of the tube. The lift and sway of the valve are limited by a member 35 held down by a spring, and by bent tongues 63 engaging a groove in the valve. If the discharge is stopped, e.g. by closing a discharge cock, the bellows stops on the discharge stroke and remains compressed until the discharge recommences, when it resumes its stroke. When the pump is used to supply a carburetter, the stoppages may be effected by movements of the needle valve at the outlet of the float chamber. A stop 110 limits the motion of the switch lever. A felt pad 75 on the fixed armature cushions the impact of the core 6.

Abstract: 1292399 Magnetic storage arrangements PLESSEY CO Ltd 23 July 1971 [19 Aug 1970] 39838/70 Heading H3B In a single wall circular domain movement arrangement in which a binary pattern of domains is propagated along a uniaxial, e.g. orthoferrite, thin magnetic layer, readout is effected by expanding each domain transversely of the propagation direction at a readout position until an abrupt division into two distinct domains occurs, the division causing a substantial electrical impulse to be generated in a conductive loop or Hall effect device. The thin uniaxial magnetic layer is located in a bias field, and circular domains of reverse magnetization are propagated by a rotating magnetic field along a path defined by a surface pattern of soft magnetic material, e.g. Permalloy. Such a pattern comprising stages A to G is shown in Fig. 4. At stage D the path A to D divides into two limbs, the domain propagating through stages E and F with progressively increased transverse dimension until at stage G the domain abruptly separates into two domains, one in each branch path. In a modification a binary pattern of domains is propagated along a second path which passes adjacent stage E, while a clock pattern of domains is transmitted along stages A to D. If at stage E a domain is present in both paths no domain expansion occurs due to magnetic neutralization, while if a binary domain is absent the division of a clock domain is able to take place at stage G, the arrangement then operating as an inverter. An inverted binary domain pattern is also available in the lower branch propagation path from stage G.

Abstract: 1310995 Vacuum sewage systems WARTSILA AB OY 19 Aug 1970 [20 Aug 1969] 39841/70 Heading E1C In a vacuum sewage system, an upper collecting chamber 4 for sewage received from an inlet 1 is normally sealed from a lower chamber 5 by a flap valve 7 which is maintained shut under the action of atmospheric pressure communicated to the chamber 5 from a vent pipe 11 via a three-way valve 10, so that sewage builds up in the chamber 4, either for a predetermined time or until the level has reached and operated a sensor 12, at which time valve 10 is caused to move to a position connecting vacuum pipe 2 with the lower chamber 5, as a result of which the sewage is discharged into the lower chamber, since its weight can then easily overcome the effect of a small counterweight on the flap valve 7, the sewage then being similarly held by a second flap valve until valve 10 has been returned to the position shown, this allowing the sewage to drop into a collecting receptacle 6. Preferably the receptacle 6 is detachable since the arrangement allows a lightweight receptacle to be used which can be removed without interfering with the maintenance of vacuum in the system.

Title: Improvements relating to precious metals and alloys thereof
Inventor: GAINSBURY PETER EDWARD
IPC: C22C1/10
Filed: 1962-05-07
Abstract: Sintered strip or sheet of a platinum group metal or alloy is made by compacting, sintering and working flake powder of the platinum group metal.  The flake powder may be compacted dry in a mould or it may be made into a paste with a liquid which will volatilize or decompose under heat, the paste is then applied to an inert support such as alumina, unglazed porcelain or zircon and sintered.  The sintering temperature is over 800  DEG C. and generally 1000-1100  DEG C. for Pt and Pd.  The liquid constituent of the paste may be water but preferably is a resin dissolved in an organic solvent such as a solution of alkaline condensed methanol methyl cyclohexanone polymer in 2-ethoxy ethanol, diacetone alcohol, 2-ethoxy acetate or similar solvent.  The resin content is about 35% and the metal content 10-90%. The thermally decomposable liquids for forming the paste include metal bearing liquids containing Pt group metals, Au or Ag, i.e. liquid bright metals, e.g. gold tertiary dodecyl mercaptan in heptane containing 30% Au.  For producing sintered alloys the metal components may be mixed together dry or the flake powder may be coated with, e.g., silver by mixing the flake with an organic silver solution and heating to reduce the silver compound.  Alternatively the liquid bright metals may be used for the source of the alloying metal. Refractory oxides such as alumina and thoria may also be incorporated in the sintered alloy either as a dry powder or as a solution in an organic solvent, e.g. thorium nitrate in acetone. The sintered compact does not adhere to the inert support and is worked either hot or cold, e.g. rolling or forging to the required degree. Specification 575,998 is referred to.
