Title: Improvements in submarine salvaging apparatus
IPC: B63C7/04
Filed: 1920-05-31
Abstract: 169,749. Lindquist, C. J. May 31, 1920. Sunken ships, raising.-A pontoon 7, Figs. 1 and 2, for raising sunken ships, is provided with mechanism for equalizing the load on the lifting cables 14, 16, comprising capstans 17, 18, Fig. 3, mounted on a table 61 sliding in channels 62 in the upper part of the pontoon, and with an anchor consisting of a chamber 10 carried by a post 11 sliding in a well 12. The pontoon floats horizontally when empty, and is submerged by opening the valve 32, Fig. 2, and operating a pump 48 to fill the anchor through the pipe 45 which parses through the hollow post 11. A partition 39 extending half-way across the pontoon confines the water at first to one end of the pontoon, which is thus caused to sink, and the anchor as it fills causes the post 11 to slide outwardly and downwardly so that the pontoon tilts and sinks still further and assumes a vertical position when about half full with the anchor resting on the sea bottom, as shown in Fig. 1. The entry of water is stopped when the working deck 27 is still above water level. The lifting cables 13, 14, 15, 16, which have previously been positioned under the vessel, are passed through guides 65, Fig. 1, located below the centre of buoyancy of the pontoon, and through guides 58. Fig. 3, into the upper chamber, and temporarily secured by pins 57. Each cable is then hauled tight in turn by connecting it temporarily by means of clamps to one of the jack-chains 19, 20, carried by the capstans 17, 18, and secured again by the pin 57 while the other cables are tightened. During this operation the sliding table 61 is locked in its central position by pins 69 inserted in holes 70 in the deck 27a. The cables 13 and 14 are then secured to the ends of the jack chain 20 and cables 15 and 16 to the ends of the jack-chain 19, and the pins 57 and 69 removed. The anchor 10 is emptied of water by admitting compressed air from a reservoir 47, Fig. 2, through the pipe 44, and then raised by means of a winch 53. Water is now discharged from the pontoon by means of a pump 21 mounted in a water-tight chamber 23 sliding on guides 24 and suspended by a cable 25 from a winch 26, raising the ship.

Title: Electrophotography
IPC: G03G15/045
Filed: 1966-07-12
Abstract: 1,165,407. Electro-photographic materials. CANON CAMERA CO. Inc. 12 July, 1966 [12 July, 1965; 28 Oct., 1965; 1 Dec., 1965; 23 Feb., 1966], No. 15109/69. Divided out of 1,165,405. Heading H1K. An electro-photographic member consists of a conductive layer, a photo-conductive layer, and an insulating layer. Either or both the conductive layer and the insulating layer are translucent. The member is such that upon the application to the insulating layer of a positive or negative charge, according to whether the photoconductive layer is N-type or P-type respectively, charges of opposite polarity are even in the absence of activating radiation injected into the photo-conductive layer from the conductive layer and bound in the region of the interface between the photo-conductive layer and the insulating layer, and is such that the insulating layer can support said charges without breakdown. In use (as claimed in co-pending Specification 1,165,405) the member is charged, then simultaneously image-wise exposed and reverse charged, and then (preferably) uniformly exposed to increase contrast. Normal dry or wet (particle suspension) development is used and the image thus formed is transferred to a receiving member by known processes. Suitable photo-conductors are cadmium sulphide and cadmium selenide (each of which may be doped with copper), zinc oxide (which may be doped with lithium), both amorphous and metallic forms of selenium, titania, selenium telluride (SeTe), lead monoxide, sulphur, anthracene, and carbazole. A binder may be present. The conductive layer may be of tin, copper, aluminium, aluminium-paper laminate, damp paper or conductive paint. The insulating layer may be of fluorethylene resin, polycarbonate resin, polyethylene, cellulose acetate, or of polyester resin: it is preferably 10-50 Á thick and may be preformed and the resin is bonded to the photoconductive layer. A member possessing at the same time high resolution and high sensitivity may have a divided photo-conductive layer; the sub layer nearest the insulating layer contains finely divided photo-conductor and that nearest the conductive layer contains coarse photoconductive granules. Specific embodiments are :-(1) aluminium bearing a layer of zinc oxide, Rose Bengal, and silicone resin and having a polyester film glued to the layer with epoxy resin; (2) aluminium bearing a layer of copperdoped cadmium sulphide in an acrylic binder and a superposed layer of fluorethylene resin; (3) a layer containing zinc oxide, bromophenol blue, Rose Bengal, fluorescein, copoly (styrenebutadiene), and chlorinated rubber, and having on one side a polyester film and on the other side a layer of conductive paint; (4) aluminium bearing a first layer of coarse cadmium sulphide particles in a copolymer of vinyl acetate and vinyl chloride, a second layer of fine zinc oxide particles with Rose Bengal in a silicone resin, and an adhered polyester film. A developed member may be cleaned of pigment particles after image transfer by subjecting the member to an A.C. discharge and then brushing the surface.

Filed: 1974-04-05
Abstract: 1453531 Boring earth &c COMPAGNIE FRANCAISE DES PETROLES 5 April 1974 [17 April 1973] 15171/74 Heading E1F A drill tool 31 has a central portion 34 (Fig. 4) which can be removed and replaced by a core barrel assembly 8 (Figs. 1, 2), the central portion 34 and core barrel assembly 8 each being attached to a member 10 having seals 12 which seats on a receiver tube 7 fixed to the tool 31, the sealing member 10 isolating the interior of tube 7 from injection or drilling mud, the core barrel assembly and tool central portion including channels for circulation of mud at a pressure less than the pressure of mud located above the sealing member 10. As described the tool 31 is rotated by a turbine (not shown) driven by injection mud 2 at high pressure in a casing 1 and a tube 7 is fixed to the tool 31. The core barrel 8 is connected by couplings 16, 17, 18, 19 and ball bearings 11 to a sealing member 10 which engages seat 13 on the tube 7, the member 10 being provided with seals 12 and a fishing head 9. Low pressure mud from the turbine circulates as shown by the arrows in Figs. 1, 2, the mud passing through channels 19a, 14a to lubricate the ball bearings 11. The central portion 34 of the tool 31 (Fig. 4) is connected to a tube 36 which is secured to a sealing member (not shown) similar to sealing member 10. When the central portion 34 is inserted into tube 7 the portion 34 engages a seat 35 before the sealing member engages seat 13 on tube 7. The high pressure mud causes the sealing member to move downwardly, breaking shear pin 42 so that wedge member 45 moves latches 38 outwardly to engage abutments 56 fixed to the tool 31. Thus the central portion 34 is rotated with the tool. Additionally or alternatively the central portion 34 may be rotated by splines (not shown) in the central portion 34 engaging grooves in the tool 31. In a modification the tool 31 is rotated by a pipe string controlled from the surface.

Abstract: 618,256. Supply systems for discharge apparatus. KIRCHNER, K. F. May 20, 1946, No. 15177. Convention date, June 1, 1945. [Class 38 (iv)] A fluorescent lamp 6 or other discharge device, having a striking voltage in excess of the voltage of a D.C. supply source 7, 8, is started by the voltage induced in a choke 15, Fig. 1, or autotransformer 16, Fig. 2, upon cessation of the charging current which flows into a condenser 9 at the moment of closing a starting switch 14. A resistive ballast 12 of large positive temperature coefficient, such as an incandescent lamp, stabilizes the lamp current under running conditions. A leak resistor 11 ensures discharge of the condenser when the switch 14 is open. The circuit of Fig. 1 is particularly advantageous when the supply 7, 8 is subject to wide voltage fluctuations, the choke condenser combination repeatedly feeding the lamp with high voltage pulses when the supply volts fall below the running volts of the lamp. The circuit of Fig. 2 may be modified by interchanging the connections of the ballast and condenser to the terminals 17, 18 of the transformer, or by connecting the lamp directly across the condenser and connecting terminal 19 of the transformer to an external starting electrode adjacent the lamp.

Filed: 1973-03-30
Abstract: 1470381 Infra-red gas analyzer MULLARD Ltd 18 June 1974 [30 March 1973] 15350/73 Heading G1A An infrared gas analyzer is arranged to measure the concentrations of a plurality of components in vehicle exhaust. Infrared radiation having passed through the gas mixture is passed through a rotating filter wheel which has sections passing peak absorption wavelengths characteristic of the various components. The detected radiation signals are stored, compared with a reference level and corrected for any overlapping regions of the absorption characteristics. As shown in Fig. 1, the exhaust gas passes through a cell formed by two concave mirrors, source 1 and detector 10 being at their foci. The filter wheel 9, is formed of a circularly variable continuous interference film but is masked off by mask 15 to allow transmission only through apertures 19 at positions corresponding, to the absorption wavelengths characteristic of the various components, Fig. 2. A projection 16 associated with a photo-electric system provides synchronizing signals for multi-plex de-coder which receives signals from the detector 10 and distributes them to respective integration circuits 35-40, which store the detector outputs corresponding to the different gas components. Integration circuit 41 is reserved for detector signals relating to cut-out 20 of the filter wheel, which characterises none of the gases but is used as a reference. Its output. is fed back to input amplifier 31 where in an automatic gain control circuit it is compared with a reference. The reference provided by 41 is used in amplifiers 42 to standardize the signals on all channels, which signals are then linearized in logarithmic units 47-51 for all but that channel including integrator 38, which does not produce a high enough output to require such correction. Overlapping absorption bands are dealt with by combining the outputs of channels e.g. the H 2 O signal from 51 with the CO 2  signal from 47, in amplifier 60, to obtain accurate concentration representative signals for all components.
