[Class 113 (i)] For defouling the sides and bottom of a floating or submerged ship's hull, the ship is traversed in contact with scrubbing devices yieldingly carried by stationary supports erected in a waterway. In the form shown, stiff wire side scrubers 5, 5<SP>1</SP> are carried by gates G which are hinged to dolphins B<SP>1</SP>, B<SP>2</SP> and which are outwardly biased by weights 2 connected to chains 3 passing round pulleys 4, 4a and provided with limiting stops 5. Buffers 6 also are provided. Bottom scrubbers 53 are carried by a horizontal beam 7 which is guided by vertical members 8 on dolphins Cl, C2 and which is upwardly biased by weights 9 connected to chains 10 passing round pulleys 11, 12. Further chains 13 are connected to the weights 9 and to hard winches 14. Pressure due to the weights 2, 9 may be augmented by mechanical means.

Abstract: 747,181. Metal-vapour discharge apparatus. GENERAL ELECTRIC CO. Jan. 26, 1953 [Jan. 30, 1952], No. 2177/53. Class 39 (1). To equalize the magnetic fields within a mercury-pool device due to the current in the cathode leads, these are formed of a number of parallel conductors 8, Fig. 1, equally spaced in a circle about the axis of the non-magnetic metal envelope portion 1. Cathode current is led by conductors 12, 13 to lower bus-bar 10 and taken off from upper bus-bar 9, after flowing equally through the four conductors 8. If the cathode is insulated from the envelope, the bus-bars 9, 10 are both insulated from the envelope; if not, only bus-bar 9 is. In another form the conductors 8, Fig. 3, start from the top of the metal envelope 1 and surround the anode seal 5, 6, 7; bus-bar 10 is electrically in contact with envelope 1.

Title: Improvements in apparatus for the projection of sound and motion picture films
IPC: G07F17/16
Filed: 1959-01-23
Abstract: 904,370. Sound-on-film juke boxes. GODIN, G. M., BOURG, R. D., and PERIER, R. I. Jan. 23 1959, No. 2569/59. Class 40 (2). [Also in Group XX] Apparatus for the projection of one of a number of different sound and motion picture films comprises a sound and motion picture projector and selecting means for choosing and projecting a desired film, the selecting means comprising a base with a series of reels each supporting a film disposed round the periphery of the base which is rotatable to bring a chosen reel into a position where the film on it can be engaged by mechanism for feeding it through the projector to optically project the picture sequence and reproduce audibly the sound track. As shown, supply spools 10 for sound and picture films 1 are carried by a disc 6 rotatable by a rubber roller 19 driven by a motor 18. When a coin is inserted in the machine a selector mechanism is released for manual operation and such operation energizes the motor 16. When the chosen film 1 is in position for feeding an electromagnet 9 is energized stopping the motor 16, the magnet core latching the disc 6 by engaging in a notch in the frame 7 and displacing against return springs a block 8 having a magnetic insert to which is attracted a metal hook 4 secured to the end of the film 1 so that the hook 3 on the leader strip 2 threaded through the projector passes through the opening 12 in the end of the film, and thereafter the electromagnet causes the projector drive motor to start so that the leader strip latches on to the film to feed it through the picture gate P and sound head 15. When the performance has finished, a contact finger of the switch 22 which bears on the film operates the switch, closing the circuit to the motor 18 and a solenoid 21 which tilts the motor and its driven rubber roller 19 so that the roller engages the reel 10 to rewind the film and reverses the projector motor. When the hook 4 reaches the finger 5, this finger 5 is moved upwardly to engage the lever 22, and operate the switch 22 to break the circuit to solenoid 21 and motor 18 thus stopping rewinding of the film, whereupon the hook 3 disengages from the hook 4 so separating film and leader strip, the finger 5 returning under gravity to the position shown and the selecting mechanism de-energizes the electromagnet 9 and energizes the motor 16 to return the platform to its original position. In a modification, the finger 5 instead of sliding in a guideway is mounted on a rail and the film and leader strip are arrested in their end positions by wedges rotated by the film and strip whereafter the electromagnet 9 is de-energized. In this modification the film has no terminal hook but a pair of longitudinally-spaced apertures in which a similarly spaced pair of hooks on the leader strip engage.

Patent GB-211125-A (GB)
IPC: C07C11/24
Filed: 1924-02-02
Abstract: 211,125. Gros, F. Feb. 8, 1923, [Convention date]. Hydrogen and acetylene are produced by subjecting gases containing methane or ethylene or their homologues to the action of electric sparks. The gases forming the starting material may comprise the distillation gases from coal, lignite, peat, and wood, e.g. lighting gas and coke oven gas, from which the components other than methane may have been wholly or partially removed, methane produced by the catalytic interaction of hydrogen and carbon monoxide, natural gases containing methane, ethylene obtained by the decomposition of ethyl alcohol in the presence of alumina, and gases obtained by the heat treatment of cellulose and resins. The reaction takes place in the annular space between a stationary insulated casing a and a rotor c driven by a pulley d. Both the rotor and stator are conically shaped and the gap between them can be adjusted by screwing the collar m into the bush n, whilst both are provided with projections e, f between which the sparks pass. These projections are made of metal such as platinum, nickel, aluminium, or copper covered with platinum or nickel and are arranged in corresponding helical lines. The gases enter the apparatus by the pipe k and leave by the pipe l. The acetylene formed is separated either by liquefaction or by dissolution under pressure in a solvent such as acetone. Benzene and tarry hydrocarbons are then eliminated. The hydrogen is subsequently removed by liquefaction and may be used for the production of methane from carbon monoxide or gases such as water gas containing carbon monoxide, the methane being then utilized as starting material. According to the examples, lighting gas under pressure is conducted over a catalyst of nickel or reduced iron maintained at a temperature of 300-400‹ C.; the resulting gas is then cooled to liquefy the methane and the latter subjected in the gaseous condition to the action of electric sparks, the products compressed, benzene and tarry constituents removed by washing with water, and the gas finally passed into a liquid such as acetone to absorb the acetylene. Any residual gas is mixed with the gases issuing from the catalytic reduction apparatus for retreatment. The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of the resulting acetylene by passing it through a coil of iron. nickel, or nickel-iron heated to red heat in order to obtain more hydrogen. This subject-matter does not appear in the Specification as accepted.

The field system consists of groups of three poles A, B, C, D, E, F, Fig. 1, and means are provided for exciting it so that the ratio between the flux in the middle or booster poles B, E of each group to the flux in the outer or main poles A, C and D, F varies with variations in the input voltage is such a way as to tend to maintain the output voltage constant. If a is the flux in each main pole, and b that in each booster pole, the necessary condition is that the ratio 2a + b should vary inversely or directly as the input voltage according as the 6-pole winding functions as the input or output respectively. The main poles have shunt windings A<SP>1</SP>, C' D<SP>1</SP>, F<SP>1</SP> and the booster poles have two windings B<SP>1</SP>, B<SP>2</SP> and El, E<SP>2</SP> connected across the supply, in parallel with the armature which has a 6-pole wave-wound input winding G, Fig. 2, and two or more 2-pole lap wound output windings H, J.
