Title: Improvements in or relating to method of and apparatus for measuring the metacentric height of ships or similar bodies
IPC: B63B9/00
Filed: 1930-01-27
Abstract: 349,486. Determining metacentric height of ships. STABILITY METER CORPORATION, 120,Broadway, New York, U.S.A.-(Assignees of Wilson, J. L. ; 24, Old Slip, New York, U.S.A.) Jan. 27, 1930, No. 2796. Convention date, Feb. 8, 1929. [Class 113 (i).] Apparatus for determining the metacentric height of ships comprises the combination of a gyroscope arranged to precess an extent commensurate with the angular velocity of roll with a pendulum to give the angle of roll, these values jointly controlling an indicator which gives the metacentric height. An athwart ship shaft 7 mounted in brackets 2, 3 on a baseplate 1 carries a yoke 11 on which the gyroscope 15 is mounted. The transverse rolling of the ship causing precession of the gyroscope is restrained by springs 31, clamped to the shaft 7 by a sleeve 32. The shaft 7 also carries a pendulum yoke member 10 supporting on pivots 13 the pendulum 14, which is provided with an extension 24 employed to move scissors members 22, 23 to the position of maximum roll. The members 22, 23 work on the inside and outside respectively of a resistance 21 wound on a quadrant 20 and serving as a potentiometer, the scissor member 21, 22 being returned to the zero position under the action of spring-controlled core rods 27, 28 of solenoids 25, 26. A similar piece of apparatus is employed to indicate the maximum velocity of roll given by the precession of the gyroscope and the two values are combined to operate an indicator such as shown in Fig. 4, where coil members 45, 46 are carried at right-angles on a shaft 47 mounted in the instrument, and carrying a pointer 49 moving over a dial 50. The coils 45, 46 are within the magnetic field of the solenoid 48 and the values of the separate voltages applied to the coils 45, 46 being determined by the positions of the scissors members controlled by the pendulum and gyroscope on the potentiometer quadrants, the coils 45,46 take up a position bearing a definite relation to the values of these voltages and the pointer 49 indicates the metacentric height on the dial 50.

Abstract: 542,123. Automatic guns. ROE & CO., Ltd., A. V., and REDRUP, C. B. Feb. 14, 1940, No. 2808. [Class 92 (ii)] Relates to cartridge fed mechanism of the kind in which the cartridges are carried in pockets formed by stitching belt portions a, b together at intervals, the stitches being torn apart by tension applied to the belt portions by spiked rollers f driven by hydraulic motors e as described in Specifications 542,119 and 542,122. According to the present invention, premature separation of the belt portions is prevented by the arms j, k of sprockets arranged on opposite sides of the belt and revolved by the cartridges. The arms act as struts to support the stitched lengths of belt between the cartridges.

A corner support for modular flooring comprises a cap 14 adjustably mounted on a screwthreaded pillar 10, the cap having a convex upper surface 15 which mates with concave under surface 17 of a pad 16 composed of hard rubber or other substance having equivalent properties. Above the pad 16 is fitted a resilient and electrically insulating cap 20 having upstanding webs 21 defining quadrantal depressions 22 which receive the meeting corners of floor modules 23. Sealing strips 25, 26 prevent egress of dust to the floor cavity. In a modification, Fig. 2, concave upper surface 115 of the cap 14 co-operates with a convex under surface 117 of the pad 16. The foot of the pillar 10 is secured in a screwthreaded tube 32. The construction permits any divergence from the truly vertical of the pillar 10 to be compensated for by manipulation of the pad 16.

Title: Improvements in and relating to the cooling of naphthalene-laden and/or tar-laden gases
Inventor: WINDT PETRUS JOSEPHUS VAN DER
IPC: C10K1/04
Filed: 1953-02-02
Abstract: <PICT:0746183/III/1> A method of cooling gases containing naphthalene and/or tar vapours comprises causing the gases to flow horizontally in a single pass and substantially in a straight line over generally vertical cooling tubes through which coolant is directed in a zig-zag path in contra-flow to the gases the length of the tubes being such and successive reversals of the flow direction of the coolant being sufficiently frequent as to ensure that tarry condensates running down the outside of the tubes can reach the bottom of the tubes without solidifying or becoming so viscous as to adhere to the tube. In apparatus for carrying out the method, the gases enter a chamber 1 at an inlet 2 and flow in substantially a straight, horizontal path over tubes 6 to the outlet 3 of the chamber and the cross-sectional area of the gas passage decreases in the direction of gas flow, either by a progressive decrease in the cross-sectional area of the cooling chamber or by a progressively closer spacing of the tubes. The tubes are divided into groups through which the coolant flows serially in zig-zag fashion and extend between headers 7, 12 each header being divided by baffles 13 into compartments whereby the tube groups are serially interconnected.  Condensates flowing down the tubes are collected in troughs formed by shallow transverse walls 16. An outlet 17 from each trough leads to a common discharge line 18 for the condensates.  Specification 681,251 is referred to.

Abstract: 1292731 Friction welding CATERPILLAR TRACTOR CO 21 Jan 1970 [4 Feb 1969] 3020/70 Heading B3R A process of friction welding an aluminium or aluminium alloy workpiece to a steel workpiece comprises cleaning the part of the steel workpiece to be welded, and providing the aluminium or aluminium alloy workpiece with a projection which at its end is of smaller cross-sectional area than that of the rest of the workpiece. Such a projection may be a conical projection which wears down as the friction between the workpieces takes place to form a weld. The aluminium workpiece may also be cleaned and various acids are described for cleaning both workpieces. The apparatus comprises an axially movable non-rotatable workpiece which is actuated by an hydraulic load cylinder and a fixed rotatable workpiece having flywheels connected to its work-holder. The rotatable workpiece is actuated by a motor via an hydraulic pump and motor assembly and is accelerated to a predetermined velocity at which point the power is disconnected. A two step load cycle is carried out by means of the load cylinder the initial thrust being of low value and the final step being of high value.

In an I.C. engine having an injection pump 11, Fig.2, an exhaust brake 1 and an exhaust-gas turbo-supercharger, a retarding means delays the closing of flap 2 until the pump delivery has been suspended. A valve 7 controls the supply of hydraulic or pneumatic pressure to piston/ cylinder devices 5, 3 and 13, 10 which respectively control the exhaust brake 1 and the delivery of injection pump 11. When the supercharger pressure in pipe 17 falls, after a reduction in pump delivery, spring 21 moves valve 20a, 20b to admit pressure medium to cylinder 3 to cause closing of flap 2. In another embodiment spring 21 is omitted and the valve is actuated from an extension (27), Fig.3 (not shown) of pump regulating rod 14. In a further embodiment the valve is omitted and a throttling orifice (9), Fig. 1 (not shown) is arranged between valve 7 and cylinder 3 downstream of the connection to cylinder 10. In an embodiment employing electrical operation of brake flap 2, Fig.4, a switch 28 controls a circuit through a relay 29 to a magnet 30 which controls the delivery of pump 11 and through a delayed-action relay 31 to a magnet 32 controlling flap 2.
