Title: Improvements in or relating to tower cranes
IPC: B66C23/28
Filed: 1966-06-14
Abstract: 1,130,459. Tower cranes. RICHIER. 14 June, 1966 [14 June, 1965], No. 26517/66. Heading B8B. The hoisting means 17 of a tower crane is suspended from a crab 12 and is actuated by a lifting cable 8 extending around pulleys 12a, 12b mounted on said crab and pulleys 9, 10, 11 mounted on the jib 3 of the crane. One end of the cable 8 is attached to a winch 7 and the other end passes over pulleys 14a, 14b on an auxiliary arm 5 and is connected to a further hoisting means 16. For operation of either hoisting means the other is first raised and then locked relative to its support whereby on operation of the winch 7 the unlocked hoisting means may be raised or lowered. The auxiliary arm 5 is mounted for independent rotation about the vertical axis on the top of the tower above the jib and is of a length slightly greater than the maximum radial dimensions of the tower whereby the arm may still be fully rotated when the crane is close to a building. Components such as 6 may be raised by the further hoisting means 16 to form an extension of the tower. In an alternative embodiment, not shown, the end of the cable 8, remote from the winch, is attached to the auxiliary arm 5 and the further hoisting means 16 suspended by a cable loop formed between the fixed end and the pulley 14b.

Abstract: 297,830. I. G. Farbenindustrie Akt.- Ges. Sept. 80, 1927, [Convention date]. Tanning with special chemicals. - Synthetic tanning agents, in solid form and requiring the addition of water only to produce a bath of requisite acidity, are obtained by the addition of solid organic or inorganic acids or acidic substances to the alkali salts of phenol condensation products containing sulphur, which are not precipitated from solution by dilute acids. The phenol condensation products are of known formation and are obtained, for example, by the action of formaldehyde and a neutral sulphide (or a bisulphide) on a phenol condensation compound containing sulphur, or by the action of a neutral sulphite and air on a phenol-sulphur condensation compound. Suitable substances for addition to the alkali salts of such agents are oxalic acid, potassium bisulphate, 2-naphthalene sulphonic acid.
Patent GB-671975-A (GB)
Title: Improvements in or relating to the treatment of metal-on-metal coatings
IPC: C25D5/50
Filed: 1949-10-19
Abstract: A metal coating is sintered to a metal base by subjecting the coated surface to the effect of an H.F. current of at least 300,000 c.p.s. to bring about the skin glow effect.  When the thickness of the coating layer is near to the lower limit of the range 0.0025 to 1 m.m. the distance between the oscillation source and the article, and the frequency, are adjusted so that the thickness of the layer of the base metal affected is greater than the thickness of the coating layer, and when near the upper limit is less than the thickness of the coating layer.  The oscillation source and the metal article are moved relative to one another and in the case of internally coated hollow articles, e.g. tubes, the oscillation source is moved through the article.  In the case of hard chromium plated articles the last traces of hydrogen left in the chromium layer are removed by the glow effect.

Title: Improvements in variable-speed transmissions for motor vehicles and the like
IPC: F16H47/08
Filed: 1956-09-04
Abstract: 842,715. Variable-speed gearing. CARP, P. J. Sept. 4, 1956, No. 26961/56. Addition to 759,555. Class 80 (2). The transmission claimed in the parent Specification is modified by providing the hydraulic torque converter coupling with a stall torque ratio of substantially 2.5 to 1 or greater, by providing the planetary gear system with a plurality of forward gear ratios and one reverse ratio, and by providing a second gear system for supplementary ratios. As shown, the hydraulic coupling 1, clutch 2, freewheel 9, and control means 3 are as described in the parent Specification. A compound planet gear 4 provides two forward gear ratios by actuating a clutch 6 and a brake band 6a and a reverse gear ratio by applying brake band 10. The planet carrier which is the driven member of the gear is connected to the planet carrier 14 of the second gear system. In this gear the annulus 5 is fixed to the final driven member 15. Application of a clutch 7 produces a solid drive in the gear whereas application of band brake 7a gives an overdrive. If desired the second gear system may be fitted between the vehicle engine and the first gear system.

Title: Gravity-controlled valves for continuous liquid supply tanks
IPC: B64D37/22
Filed: 1956-09-04
Abstract: 797,824. Emptying tanks. JAY, K. W. Sept. 4, 1956 [Sept. 7, 1955], No. 27030/56. Class 21. [Also in Group XXIX] An oil or fuel tank for aircraft with a number of differently positioned outlets, has a gravity actuated valve for each outlet comprising a piston 23 movable over ports 21 in a cylinder 14 under the control of a tension spring 24 and a weight 26 attached to the piston by a flexible connector 27, the weight applying to the piston a greater force than the spring so that when the valve is in the vertical position, as shown, the piston is drawn down upon a stop 19b to close the ports 21. The weight 26 is housed within a perforated box 12 contained within the tank and is offset to one corner thereof whereby when the tank is tilted so that either of its sides 12A, 12B is at the bottom the weight 26 rests on that side and allows the spring 24 to open the valve. The valve is also opened when the tank is completely inverted but is closed when the tank is tilted such that either of the sides opposite the sides 12A, 12B is at the bottom owing to the fact that the length of the flexible connector 27 is insufficient to allow the weight 26 to touch either of those sides. A passage 23a in the piston 23 equalizes the pressures on each side of the piston. The inlet from the tank is through the perforations 12a in the box 12 and passages 20 in the valve casing. The outlet from the ports 21 is by way of an annular chamber 15 to a pipe 22a and this pipe may connect with other valves at other corners of the tank. In one embodiment four such valves are described at four corners of a tank whilst in another embodiment a valve is placed at each of the eight corners of a tank.
