Title: Fuel cell battery
IPC: H01M8/08
Filed: 1974-04-25
Abstract: 1457024 Pumping liquids by gaseous pressure VARTA BATTERIE AG 25 April 1974 [26 April 1973] 18158/74 Heading F1R [Also in Division H 1] A pump 81 for supplying electrolyte 4 to a fuel cell battery (see Division H 1] comprises a vertically movable float 82 provided with a magnet 88. The magnet is attracted to a nickel ring 87 and the upthrust on the float in the electrolyte causes a valve cone 90 to close a gas outlet 85. The reactant hydrogen and oxygen gases fed to the fuel cells are exhausted through pipes 83, 84 and displace the electrolyte from the pump into the fuel cells via a pipe 2. The electrolyte is returned to a tank 3 via an outlet pipe 7. The level of the electrolyte in the. pump falls until the effects of gravity overcome the combined magnetic and buoyancy effects whereupon the outlet 85 is opened allowing the escape of gas and the inflow of fresh electrolyte into the pump through a valve 89. The float then returns to its upper position and a fresh cycle of operations commences.

Title: Improved manufacture of liquid fuel from petroleum
IPC: C10L1/04
Filed: 1919-07-21
Abstract: A liquid fuel is obtained by distilling crude petroleum by the aid of superheated steam or inert gases until a residual pitch of high melting-point, e.g. 192 DEG  F., is obtained, and then mixing the pitch while still hot with an oil of low viscosity, e.g. 49 DEG Saybolt at 100 DEG  F., and low cold test, e.g. pouring below 0 DEG F. The oil so used may be the " pressure tar " obtained as a residue in distilling heavy petroleum distillates (preferably freed from lubricants and waxes) under pressure for the production of gasolene, as described in Specification 29862/12, [Class 32, Distilling &c.]. The pitch and pressure tar may thus be derived from the same crude oil.  The crude petroleum is continuously distilled by passage through a series of stills, the pressure tar being supplied to the last still.

Title: Improvements relating to the recording of television pictures on film
Inventor: MCKEE KENNETH MACINTOSH
IPC: H04N3/40
Filed: 1951-08-01
Abstract: 698,574. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 31, 1952 [Aug. 1, 1951], No. 18184/51. Addition to 650,879. Class 40 (iii). Apparatus for recording television images on film as disclosed in the parent Specification, wherein a plurality of cinematograph films are exposed in alternate or cyclic order, for times such that each records sequencies of partial pictures (e.g. single frames of interlaced pictures), is modified in that each film is exposed for times corresponding to one complete television picture. The modification reduces the amount of film utilized in making a recording, and eliminates the interlacing errors due to incorrect registry where the films are combined to produce a final film. One modification merely involves the operation of the camera shutters by the frame synchronizing pulses so that the films are exposed for the duration of one complete picture. Alternatively the apparatus may be modified by dispensing with the prism system employed to divide the light beam from the cathode-ray tube screen to the cameras. The scanning circuits are then arranged such that alternate or successive pictures appear on different areas of the screen, the areas being contiguous or disposed one above the other. Separate lenses are provided for focusing the images from the different areas on to the gates in the separate cameras. With this modification it is possible to dispense with the camera shutters. The invention is applicable to the recording of colour and stereoscopic television pictures, in the latter case the stereoscopic components are transmitted sequentially and the films, after developing and printing, are not combined in a final film but are reproduced and viewed simultaneously through suitable optical filters. In preparing a final film from the separate films the separate films may be printed on the final film in adjacent positions by employing separate printing heads. Alternatively one film may be printed on first, leaving spaces for the other film.

Title: Improvements in or relating to magnetostatic relays
IPC: H03K17/60
Filed: 1959-05-28
Abstract: 878,061. Magnetic amplifiers. COMPAGNIE INDUSTRIELLE DES TELEPHONES. May 28, 1959 [June 2, 1958], No. 18224/59. Addition to 871,623. Class 40 (9). A magnetic amplifier comprises a winding a on a saturable core fed by alternating current, the output of the winding passing through a rectifier Rd to be fed across the base resistor R 2  of a transistor T whose collector current feeds the load Rc. The magnitude of the negative half cycle current I m  from the core is shown in Fig. 3 in terms of the D.C. control ampere-turns N c , I c  of the control windings   b.c. When I m  exceeds a threshold value U o  / R 2  the emitter current I e  flows, the corresponding curve being shown in Fig. 5. The collector current I s  (and hence the load current) follows a similar curve with the exception that the current is limited to a value I 1  which occurs when the collector and base achieve the same potential. The characteristic of the amplifier is thus as shown at G 4 , Fig. 6. Bi-stable operation may be effected by the introduction of positive feedback via winding d. A resistance may be inserted between point F and the collector of the transistor to prevent excessive discharge current from the smoothing condenser Ca from damaging the transistor.

Filed: 1968-04-18
Abstract: 1,270,927. Transformers and inductors; camoperated electric switches. MIDLAND TRANSFORMER CO. Ltd. 18 July, 1969 [18 April, 1968], No. 18264/68. Headings H1N and H1T. In the coil tapping apparatus of Fig. 4, turns 41-46 of the coil are associated with respective main tapping elements 49-54 which move within a common current collecting bar 47 when operated by means of a slider 61 moving parallel with the coil, along the screw 62. Bridging tapping elements 55-59 are each associated with respective adjacent turns, e.g. tapping element 55 contacts both turns 41, 42 when operated. The slider 61, which may alternatively be a roller or cam, is offset (see Fig. 6), such that during the period between the slider part 64 leaving tapping element 50 and engaging element 51, slider part 63 operates element 56, thus ensuring the continuity of the circuit. The electrical-contact making end of the bridging tapping element has a relatively high resistance, carbon, face so as to limit the circulating current during the short period of interconnection of the two windings. In an alternative embodiment, Figs. 1-3 (not shown), adjacent main tapping members on separate current collecting bars, are, for a short transitional period, both in contact with their respective turns and a centre-tapped inductance choke is connected across the two bars so as to limit the circulating current. In alternative embodiments the contact surface of the main tapping elements may be laminated, the laminations of which spread on engaging the associated turn, or may be pyramidal or conical and engage an appropriate seating in its associated turn. Also, a wiping action may be present when the tapping element and the associated turn engage, e.g. the tapping element may be rotated by a disc engaged off-centre by the operating means. The direction of movement of the main tapping elements is not necessarily perpendicular to the contact surface of the elements.

Title: Improvements in and relating to titanium and aluminium salt solutions
Inventor: OLIVER DEREK JOHN
IPC: C09C3/06
Filed: 1959-05-29
Abstract: An aqueous solution of aluminium and titanium sulphates is prepared by filtering an aqueous suspension of a titanium dioxide hydrolysate using an organic filter aid, incorporating hydrogen peroxide, or an inorganic peracid, or a sodium, potassium or ammonium salt of an inorganic peracid, with the filtered titanium dioxide in an amount such that the final solution is substantially free from carbonaceous colouring matter, dissolving the titanium dioxide in sulphuric acid, and forming a solution containing aluminium sulphate in admixture with the titanium sulphate.  The filter-aid may be wood flour.  The titanium dioxide may be washed after filtering.  The aluminium sulphate may be prepared by reacting aluminium, aluminium hydroxide, or hydrated alumina with sulphuric acid, and may be formed either apart from, or in the presence of the hydrolysate.  Alternatively, aluminium hydrate may be dissolved in an excess of sulphuric acid and the hydrolysate added to the resulting solution.  The sulphuric acid may have a concentration of from 93 to 20% oleum. The mixed solution obtained will normally be hot and viscous and may be cast in moulds in which it solidifies on cooling, or it may be diluted to prevent solidification.  The solution may be employed for the surface treatments of pigments and fillers, such as titanium dioxide, blanc fixe, or calcium sulphate by depositing hydrated titanium dioxide on the surface of the pigment or filler.ALSO:The surfaces of pigments, such as titanium dioxide, mixed pigments containing titanium dioxide, and coloured pigments, may be treated by depositing on their surfaces mixed hydrated titanium dioxide and alumina from an aqueous solution of titanium and aluminium sulphate substantially free of carbonaceous colouring matter (see Division C1).  In an example, a yellow titanium pigment was prepared by forming an aqueous suspension containing 100 parts titanium dioxide, 16.5 parts hydrated nickel sulphate, and 18 parts antimony oxide, drying, calcining, and grinding.  The resultant pigment was dispersed in water with the addition of sodium silicate solution, and the titanium and aluminium sulphate solution was then added. The pH of the resultant mixture was brought to 7 by the addition of sodium hydroxide solution, with the resultant deposition of the hydrous oxides of silicon, aluminium, and titanium. The suspension was then filtered, washed, dried, and disintegrated to give an improved pigment.
