Abstract: 923,260. Collapsible mobile tower-cranes. ETABLISSEMENTS F. POTAIN & CIE. May 12, 1961 [May 18, 1960], No. 17363/61. Class 78 (4). As the tower 5a, Fig. 1, of a crane is raised into a vertical position the jib 7 is swung into a horizontal position by a member 11. As described, the member 11 is a cable, connected between a bracket 12 on a support 3 and a point 10 on a jib-carrying head 6, which tightens as the tower is raised by a winch 13. the part 5b of the tower telescopes within the part 5a. Two cables 11 may be provided, one on each side, or a single cable may be passed round two pulleys on the head 6, the ends being attached to the supports 3. In the embodiment shown in Fig. 6, a cable 11, which is initially taut, extends between points 10 and 12 and passes over pulleys 17, 18 mounted on the tower. In Fig. 9 a rigid strut 21 is connected between a pivot 20 on a bracket 19 on the jibcarrying bead 6 and a pivot 22 on the support 3, to form a parallel linkage with the tower. In a modification of this embodiment the strut 21 is arranged above the tower instead of below it when the tower is horizontal. In Fig. 11 the tower is mounted on brackets 3a and raised by a winch 13 and cable 14, a similar parallel link 21 being provided. In Fig. 12 a cable 11 which raises the jib does not form a parallel linkage with the tower. To compensate for this the cable 11 is wound on a subsidiary drum of a winch 24 which also raises the tower by means of a cable 14.

IPC: F16D65/22
Abstract: 1,051,671. Master cylinder for hydraulic brakes. SOC. ANON. FRANCAISE DU FERODO. March 25, 1964 [March 26, 1963], No. 12710/64. Heading F2F. A master cylinder 10 comprises a piston assembly 14 defining two primary chambers 19, 21 from which the piston, when operated, expels equal or proportional volumes into two primary conduits 78, 80 leading to two brakes 70, 71, a secondary chamber 20 connected to secondary conduits 82, 83, 84 balancing the reactions of these two brakes and a safety unit 92-94 which senses the pressure in the secondary conduits and leaves the primary pressures unbalanced when it is high but balances them when it is low, the primary chambers 19 and 21 being contiguous and followed by the secondary chamber 20. The safety unit which senses the secondary pressure comprises a poppet or clack-valve on a piston 92 seating at 96a so as to seal off from each other passages 97 and 98 from the two primary chambers. The piston 93 is held forward against the seating by a spring 101 but can be moved therefrom by pressure in the passage 97 to interconnect the latter with the passage 98. The travel of the piston is restricted by its shank 99 which extends into a chamber 94 connected to the chamber 20 and through a valve 64 to brake circuits 84 and 89. When the brakes are applied rise in the pressure in the primary brake cylinders 74 and 76 lead to a rise in pressure in the secondary brake cylinders 75 and 77 and secondary conduits, causing the valve 64 to close. If the consequent pressure in the chamber 94 is sufficient the piston 92 moves forward again on to the seating 96a. Chambers 19, 20, 21 are all connected to a reservoir container 22, chambers 19 and 21 being separated therefrom by valves 23, 25 which are held half-open by pistons of the assembly 14 when the brakes are off, but which are otherwise closed. Chamber 20 has no valve in this connection. An indicator light is provided at 67..

Abstract: 1,052,550. Stereoregular polypropylene film. HERCULES POWDER CO. June 2, 1965 [June 12, 1964], No. 23476/65. Heading B5B. [Also in Division C3] An elastic polypropylene film is formed by extruding polypropylene at 220-290 C. into a film, subjecting the film to a melt draw down of # 24: 1, quenching the film at 80-110C. within #- inch from the extrusion die, and heat-treating the film at 130-150 C. in the relaxed state. The films are of stereoregular polypropylene, capable of at least 80% recovery from an elongation of 75% in the machine direction. The polymer may contain an azido cross-linking agent, e.g. a sulphonazide or azidoformate, there being e.g. 0À1-0À8 moles agent per mole polypropylene. In the Figure (not shown), film extruded from die 3 is quenched by inert liquid 5, e.g. H 2 O, at 80- 110 C. The film is drawn through the liquid by nip rolls 7 and 8 positively driven at 24-80 times the linear rate of extrusion of film 14 through die 3, thus stretching the film at the molten portion immediately following die 3. From nip rolls 7 and 8 the film passes into a heattreatment oven 9 wherein the film is maintained free of tension at below its softening point. The film passes round idler rolls 10 in the oven, and leaves the oven via nip rolls 11 and 12 driven at the same rate as the inlet nip rolls 7 and 8, and is then wound into rolls.

A disc brake for vehicles comprises a conventional hydraulically actuated disc brake mechanism applying friction pads 4 against radially extending surfaces of the brake disc and a secondary shoe-drum brake used as a parking brake in which a single freely mounted brake shoe 9 is adapted to engage the inner cylindrical surface 1a of the brake disc flange when a two-armed lever 8 pivoted at 7 is actuated. The arm 8b of the lever 8 engages the centre of the brake shoe 9 which can abut against two abutment members (11), (12) (Fig. 2, not shown) disposed on an axle tube 10 to ensure that the shoe acts as a primary shoe in both directions of rotation of the brake disc 1 so that the applying force on the parking brake is increased by self-energization in both directions of rotation of the brake disc. Reference has been directed by the Comptroller to Specification 688,382.

A method for recovering a quaternary ammonium salt from an acrylonitrile electrohydrodimerization effluent by removing water-soluble impurities involves extracting with the effluent a mixture of acrylonitrile and water to form an aqueous salt phase and an organic phase, separating and concentrating said aqueous-salt phase and thereafter extracting at least a portion of the resulting aqueous phase containing the quaternary ammonium salt with acrylonitrile in the presence of not more than 0.8 parts by weight of water per part of quaternary ammonium salt to provide a substantial portion of water soluble impurity and a quaternary ammonium salt-containing acrylonitrile phase. The aqueous phase is preferably extracted with 2-20 parts by wt. of acrylonitrile per part of quaternary ammonium salt. The process effects separation of water-soluble impurities such as organic acids, salts thereof or divalent sulphate ions from the quaternary ammonium compound which can then be reused as the electrolyte in the said process without any detrimental effect, compared with fresh electrolyte. Suitable quaternary ammonium salts are tetra-alkylammonium alkylsulphates, arylsulphonates and alkarylsulphonates where each alkyl group has 1-4 C atoms. The examples relate to tetraethylammonium ethyl sulphate.
