Abstract: 1,224,948. Equalizing tension in ropes; transshipping at sea. VYSSHEE MOREKHODNOE UCHILISCHE. 24 June, 1969 [24 June, 1968 (2)], No. 31949/69. Headings B8B and B8E. A crane for transferring cargo 22 from one ship 1 to another 8 under rough sea conditions comprises a luffing, slueing boom 3 with a jib 4. Hydraulic cylinders 10, 11, Fig. 2, are interconnected via a pipe-line 12 so that as the boom 3 is luffed by a hoist 7 the jib 4 remains horizontal. A load hoist 5 with a triple drum is connected by ropes 15, 16, 17 to a cargo suspension 21 over sets of pulley blocks 27, 28, 29, respectively, Fig. 4, which are mounted on a movable shaft 23 and a stationary shaft 24. The shaft 23 is connected to a pneumatic cylinder 25 supplied with air from an accumulator 26. The shafts 23, 24 also support pulley blocks 30 which guide a follow-up rope 9 connecting the ship 8 with a hoist 6. In use the tension in the rope 9 is pre-set using the hoist 6 and any movement of the ship 8 is compensated by the cylinder 25 moving the shaft 23, simultaneously adjusting the ropes 15, 16, 17 which thus maintain equal tension. Swinging of the cargo 22 is minimized by the three rope suspension 15, 16, 17, while luffing the boom 3 with the hoist 5 stopped results in horizontal displacement of the cargo 22.

Title: Improvements relating to electro-magnetic waveguides
IPC: H01P5/02
Filed: 1946-10-30
Abstract: 624,776. Wave-guides. MILLING, M. C. CROWLEY-, and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 30, 1946, No. 32233. [Class 40 (v)] A telescopic joint between two sections of wave-guide, slidable one over the other, is provided with matching means to prevent reflection at the joint, and sealing means to prevent leakage. One of the sections may be a connection between two main wave-guides of equal cross-section. Matching may be effected by stepping the wave-guide wall to form a transformer section, or by a suitably placed diaphragm or post. If the impedances of the guides are unequal, but bear a definite relationship, they may be matched by removing a length #g/4 of two adjacent faces of the smaller guide 2, Fig. 6, where #g is the geometric mean of the wavelengths in the two guides. Leakage at the joint may be prevented by providing quarter-wave chokes in one or both of the sliding surfaces. The chokes may be formed by a quarter-wave recess in the outer surface of the inner guide, or by two recesses spaced apart by a quarter wavelength. As shown, Fig. 9, a quarter-wave recess 9 is formed in the outer surface of the inner guide 2, while a second quarter-wave recess 11 is formed in the inner surface of the outer guide 1. In another embodiment, Fig. 10, the outer wave-guide 1 slides between the double walls of the inner wave-guide 2. Quarter-wave recesses 9, 14 are formed in the opposing faces of the double wall. Specifications 624,780 and 624,781 are referred to.

Abstract: 341,144. Cables. BEAVER, C. J., Bell Place, Stamford Road, Bowdon, Cheshire, and GLOVER & CO., Ltd., W. T., Trafford Park, Manchester. Oct. 23, 1929, No. 32242. [Class 36.] A device for maintaining the pressure in an oilfilled cable independently of the expansion or contraction of the oil, comprises a flat tube adapted to be wound spirally on the cable. A thin metal web is formed on one or both edges of the tube, each turn of the tube lying on the web portion of an adjacent turn, so that, in position on the cable, the tube forms a continuous metallic screen and exerts a uniform pressure on the insulation. In the construction shown, a flat strip 1 of metal tape is folded upon itself so as to form a shallow tube 3 and a thin web 4, the wall 5 of the tube being bent downwards and joined along its edge 7 to the web 4 by soldering, brazing, or welding. In order to make the tube flexible and to limit its collapse under pressure, corrugations or inwardly projecting portions 8 are formed in the wall 5. The tube may be connected to a source of gaseous pressure, or may be formed as a series of gas-filled containers. The tube may be formed in one operation by a machine which first forms corrugations in one part of the strip which is then folded over and joined to the other part; or two metal tapes, one of which is corrugated, have their offset edges placed together and joined. The offset edges may be provided only in the corrugated tape.

Abstract: 741,976. Tractor-mounted implements. INTERNATIONAL HARVESTER CO. Nov. 23, 1953 [Nov. 22, 1952], No. 32414/53. Class 6 (1). [Also in Group XXXI] A linkage for attaching mounted implements to a tractor comprises a U-shaped drawbar 31 connected by a pivoted member 34 to the tractor, the limbs of the drawbar carrying sockets 59, 60 adapted to receive spaced spigots 61 on the implement, and further comprises a second U- shaped member 18, the arms 27, 28 of which are pivotally linked to the drawbar-limbs 44, 45 by elements 29, 30, 52, 53 which permit both lateral and vertical floating of the drawbar 31 relatively to the tractor, these elements being optionally lockable to eliminate the floating action. The drawbar 31 is carried at its front end by a pivoted bail 34 which is linked by a rod 35 to a lateral power-lift arm 37 on the tractor. The U-shaped member 18 passes through a pair of spaced plates 16, 17 pivoted to the tractor chassis. The plate 16 houses a ball and socket bearing 19 for the shaft 18 while the plate 17 has a slot 20 enabling this end of the shaft to be raised by a bell-crank 21, 24 connected by a rod 25 to a second lateral power-lift arm 26. The members 48, 49 are channel-section links the webs 50, 51 of which rest on the arms 27, 28 so as to be positively movable therewith only on upward movement of the arms. The links are universally-jointed to dependent links 52, 53 which are pivoted on pins 56 to members 57 pivoted to the limbs 44, 45. Insertion of pins 83, 85 locks the members 49, 28 and 53, 57 together thereby eliminating floating movement between the arms 27, 28 and the drawbar limbs 44, 45. The arms 27, 28 are lifted by a doubleacting hydraulic ram 72 pivoted to the plate 17 and having its piston-rod 74 pivoted to a standard 76 pivoted to an L-shaped lever 78. The lever 78 is pivoted at 79 in a channel-section arm 80 integral with the shaft 18, and when locked to the arm by a pin 90, enables the arms 27, 28 to be positively moved in either direction under hydraulic power. Removal of the pin 90 permits power-lifting only. The sockets 59, 60 incorporate spring-loaded detent-plungers 65 which engage slots 69 on the spigots 61. The ram 72 and further rams actuating the lift-arms 27, 37 are supplied with oil from a pump on the tractor. Specification 724,355 is referred to.

Title: Improvements in the production of arylaluminium compounds
Inventor: LAUTENSCHLAGER HANS
IPC: C07F5/06
Filed: 1961-09-12
Abstract: Arylaluminium compounds may be produced by reacting aryl halides and activated aluminium.  Suitable aryl halides include iodobenzene, bromobenzene, chlorobenzene, 1-chloronaphthalene, 2-chloronaphthalene, halo-toluenes and halo-xylenes.  Compounds with several halo-phenyl radicals or with more than one halogen attached to the phenyl nucleus may be used.  The aluminium should be comminuted e.g. aluminium dust, powder or grit, and may be activated by mechanical and/or chemical means.  A halide of an element of Group Ia, IIa or IIIa may be present, or may be added to the reaction product.  A reducing metal e.g., lithium, sodium, potassium, magnesium, calcium, barium, zinc, titanium or magnesium may also be present, and if desired the aluminium may be used as an alloy.  Inert solvents such as aliphatic or aromatic hydrocarbons may be used, but it is preferred to use as solvent the aryl halide employed in the reaction.  The immediate product of the reaction is a sesquichloride, which by reaction with a p  Group Ia, IIa or IIIa halide may be separated into its components, (thus phenyl-aluminium sesquichloride reacts with sodium chloride to give sodium phenyl aluminium trichloride and sodium diphenyl aluminium dichloride) or which by reaction with a reducing metal gives a triaryl aluminium compound.
