Title: Life saving arrangement for a vessel
IPC: B63C9/22
Filed: 1974-06-20
Abstract: 1426995 Launching inflatable lifeboats INTERCONTINENTAL MARINE Ltd 20 June 1974 [26 June 1973] 27414/74 Headings B7A and B7S An inflated lifeboat 10 (or an uninflated lifeboat in a buoyant container) is lashed to a ship's deck by straps 14 and is released automatically as the ship sinks, e.g. by buoyancy forces bursting the fastening 24. A buoy 12 is held by a strap 36 to the transom 30 of the lifeboat, and remains anchored to the sunken ship. The buoy also carries a flashing light 103, radio transmitter 109 and containers of marker dye and shark repellant. The buoy and boat are initially kept together to minimise the likelihood of fouling on rigging, but a trip line 45 about 50 feet long and attached to the sinking ship releases the fastening 42 on the strap 36 so that the buoy and boat float apart but remain connected by a line 125. Where the lifeboat is launched uninflated (Figs. 5 and 6, not shown) it is stowed in a container which opens into two halves when the boat is inflated. The boat is automatically inflated by CO 2  when a line connected to the ship is pulled taut. The buoy is as described in Specification 1,416,048, and has a reel carrying an anchoring cable attached to the ship.

Abstract: 602,557. Tip wagons. JONGERIUS, N. V., J. Oct. 18, 1945, No. 27427. Convention date, Dec. 21, 1943. [Classes 103 (iv) and 108 (i)] [Also in Group XXX] A vehicle or other body 2 is tipped hydraulically by means of a piston-rod 11 thrust between a pair of jointed links 5, 6 which are connected by their free ends to universal joints 8, 9 on the body and chassis respectively. The hydraulic cylinder 13 is connected by tension bars 14 to the hinge joint 7 of the links and the end of the piston rod 11 is provided with rollers 10 which bear on the links. The body is supported by pivots 4 in bearings 3 on the frame and when being tilted to the side or ends the corresponding pivots are locked in the bearings. The opening operation of either the side walls or rear wall may be performed automatically during the locking operation of the corresponding pivots 4. The links may be curved in such manner that the tilting movement of the body is obtained by a substantially constant hydraulic pressure throughout the lift. The body may be mounted on a turntable.
Patent GB-424506-A (GB)
Title: Improvements in or relating to the manufacture of condensation products from alcohols and phenols
IPC: C07C37/16
Filed: 1933-10-05
Abstract: Condensation products of alcohols and phenols are manufactured by effecting the condensation by means of zinc chloride in the presence of a volatile liquid having a boiling point lower than the appropriate operating temperature, which in the case of primary alcohols is about 180 DEG  C. and in the case of secondary and tertiary alcohols (to which the process is particularly applicable) about 130 DEG  C.  In the former case toluene and in the latter benzene or isohexylene are suitable, the last substance being advantageously used when the alcohol is methyl isobutyl carbinol, since in this case some isohexylene is produced in the reaction.  The zinc chloride need not be anhydrous, but may be in the form of an aqueous solution, e.g. obtained by concentrating the solution remaining from a previous operation.  The phenol is preferably employed in slight excess over the molecular proportion.  The reaction may be effected by adding the volatile liquid, the phenol and the alcohol to the zinc chloride solution, heating, preferably under reflux, separating the upper layer containing the condensation product, removing the volatile liquid, washing the condensation product with water to remove zinc chloride and purifying it, e.g. by vacuum distillation.  In examples, phenol is condensed with methyl isobutyl carbinol in the presence of (1) isohexylene, and (2) benzene.

Title: Device for the electrolysis of alkali metal chlorides with mercury cells

Abstract: 654,381. Electrolysis of alkali metal chlorides. NORA, O. DE. Oct. 15, 1947, No. 27607. Convention date, Feb. 27. [Class 41] In apparatus for the electrolysis of alkalimetal chlorides by means including a cathode of mercury which forms an analgam and is subsequently recovered for return to the electrolytic apparatus, the mercury is circulated by a single pump through at least two cells arranged in series or in parallel, the cells are coupled electrically in series, and means are provided for interrupting the flow of mercury to prevent short-circuiting. In the arrangement shown in Fig. 1, three cells A1 A2, A3 are connected in parallel to an amalgam decomposer D and a pump P. Valves E1, E2, E3 and U1, U2, U3 are provided which are capable of interrupting the metallic continuity of the mercury so that the mercury can flow without the passage of electric current, and therefore the connection of the cells electrically in series is unaffected. Instead of one decomposer, three may be provided, connected each to a cell. In the arrangement shown in Fig. 3, the cells are connected in series with the pump P and decomposer D. The valves shown are similar to those shown in Fig. 1. In a modification there are provided two pumps, one for each pair of cells, and four decomposers, one for each cell.

Abstract: 495,593. Addressing-machines. ADREMA MASCHINENBAUGES. Oct. 15, 1937, No. 28084. Convention date, Oct. 15, 1936. [Class 100 (ii)] In addressing-machines in which printing-plates 3 fed in the direction of their longer sides across a table 1 are adapted to print on strip-like sheets 7 a number of impressions arranged side-by-side parallel to the longer sides of the sheets, the sheets are fed intermittently to a printing station 6 transversely to the direction of their longer sides and at right-angles to the printing-plate track by belt conveyers and during the feeding movement strike against automatically-controlled stops whereupon, after each impression, they are fed sideways by feed-sectors, and, after the last impression, are ejected at rightangles to the track of the plates and delivered by belt conveyers. The sheets 7 are fed out of a box 8 by rotary segments 10 on to belts 11, 12 which advance the sheets up to a fixed stop 18 and to movable stops 19 carried by an angle bar 20 rotatable about a shaft 24 carrying rollers 25. The first impression is printed, and the sheet is then moved sideways in steps, to receive further impressions from the same plate, by a rotary segment 42 assisted during the last stage by a segment 43 ; rollers 49, 50 let into the table-top co-operate with the segments. The sheets are then resting on the belt 12 and on belts 26, 27, delivery being effected by raising the stops 19 and lowering the rollers 25. The stops 19 and the rollers 25 are actuated by a rod 32 operated from a cam 39 on the same shaft as the rollers 10, the rod 32 being attached to a triangular plate 29 to which the bar 20 and a crank 28 for rotating the shaft 24 are connected. The Specification as open to inspection under Sect. 91 comprises a modification in which the segment 43 lies between the belts 26, 27 and one of the stops 19 is replaced by a plate arranged alongside the belt 27 and adapted to be pressed on to the sheet by a cam carried by the segment. This subjectmatter does not appear in the Specification as accepted.

Abstract: 196,545. Hunter, W. C., and Sims, F. W. Oct. 19, 1922. Dolls.-A " sleeping " doll has means by which the eyes are closed only after the doll has been rocked. The eyes 1 are pivoted in the head, as usual, and are provided with a balance weight 2 to close them when the doll is recumbent. The eyes are prevented from closing, however, by a cranked lever 5 which is pivoted in the head and has one end formed as a detent .5<b> that engages a stop 4 on the eyes. The other end of the lever rests in a slot in the end of a casing 7 which contains a ball .8. When the doll is held in a child's arms, the lever 5 prevents the eyes from closing, but when the doll is rocked, the ball 8 strikes the other end of the lever and disengages the stop 4, thus allowing the eyes to close. Instead of a cranked lever, a straight arm pivoted at one end to the casing 7 and provided at its other end with a detent may be employed. The ball may also be free to roll about in the head, thus dispensing with the casing 7. A secured catch may also be provided to release the lever 5 when the doll is rocked sideways.
