Title: Improvements in or relating to copying book-keeping apparatus
IPC: B41L3/14
Filed: 1960-09-08
Abstract: 905,995. Autographic registers. KONTEK SYSTEM A.B. Sept. 8, 1960 [Sept. 22, 1959], No. 31022/60. Class 16. Copying apparatus comprises a box-shaped housing 1 having a step-feed mechanism for feeding a blank holder 5 line by line towards the rear over the top surface of the housing, an envelope magazine 10 which is transversely displaceable and has a vertically adjustable bottom 11, and a control member 24 which energizes an electromagnet 15 and causes the holder 5 to advance one step over the base and the magazine to be pushed out partially beyond one side of the housing, Fig. 2, so that the inscribed envelope can be removed. Operation.-After a line has been filled in on the sheet in holder 5 mounted on a rail 6 and transferred to the uppermost envelope, member 24 is depressed to close spring contact 27 and energize the coil 15 which attracts a core 17 hinged to a lever 18. The lever 18 embraces a pin 20 attached to the magazine and as the lever swings the magazine 10 is pushed outwardly against the action of a spring 12. A catch 22 snaps down behind a projection 14 of the magazine in its extreme position to lock it and actuate a contact 28 to interrupt the current supply to the coil. A pawl 9 is mounted on a pillar on the magazine extension 14 and engages one of the teeth 7 on the rail 6 so that as the magazine is moved to the right the sheet in the holder 5 is advanced by one step. Pressure on the other end of member 24 releases the pawl 9, disengages the catch 22, and thus releases the magazine which is returned to the writing position by the spring 12. The plate 11 is then raised so that the envelopes are pressed upwards against the edge 13. If the electric supply fails the magazine may alternatively be pushed out manually by a rod 30.

Title: Gas turbine plants
Filed: 1953-11-11
Abstract: <PICT:0748163/III/1> In a gas turbine plant burning a fuel containing substances liable to form harmful combustion products, the fuel is distilled and the lighter fractions are burnt in a combustion chamber before the turbine and the remainder in a second combustion chamber after the turbine and before a heat exchanger heating the air entering the first combustion chamber.  In the arrangement shown, Fig. 4, the fuel is vaporised and the vaporised fuel which is thus freed from harmful constituents is burnt in the combustion chamber 145 arranged in front of the turbine 147 and the residue in the combustion chamber 152 which discharges through the heat exchanger 140 to atmosphere.  The raw fuel is supplied through a pipe 101 to a collecting vessel 102 from which it is forced by a pump 104 to a nest of tubes 106 of a preheater 107.  The preheated fuel then flows through a coil 111 in a heater 110, supplied with air by a blower 114 and heated by a burner 113.  The heated fuel passes through a reducing valve 117 into the expansion chamber 118 of a vaporizing device 119 in which a sub-atmospheric pressure is maintained.  The heavier fractions are collected in the bottom of the expansion chamber.  The fuel vapour is led through a pipe 120 to the preheater 107 where it condenses and is then drawn off by a pump 121.  Float actuated valves 155, 156 prevent the fuel levels in the preheater 107 and vaporizing device 119 from falling too low.  An ejector 125 maintains the pressure in the chamber 118 below atmospheric.  The condensed fuel vapour is supplied to the combustion chamber 145 and the heavier fractions are supplied to the combustion chamber 152.  In a modification of this arrangement, the compressor 136 is formed in two stages with an intercooler between them and the turbine 147 is formed in two stages, one of which drives the compressors and the other supplies useful power.  In this arrangement, the combustion chamber 152 and heat exchanger 140 is arranged in parallel with the turbine exhaust pipe from which the combustion air is supplied by a blower.  Further the heat for the heater 110 is supplied by combustion gases extracted from the turbine inlet.  The heat exchangers may be cleaned by injecting sand into the turbine exhaust gases.

Title: Improved automatic meter
IPC: G07F15/04
Filed: 1954-10-29
Abstract: 795,467. Locks. HOBBS, E. W. Jan. 30, 1956 [Oct. 29, 1954], No. 31309/54. Class 44 [Also in Group XVIII] A gas, electricity or other commodity meter of the pre-payment type is provided with a lock which relies for its security upon the use of a succession of combinations or keys, so that the meter can be preset to deliver a measured quantity, only if the lock is operated by the correct combination or key, the purchase price of such combination or key normally being equivalent to the price of the quantity to be delivered. As applied to a pre-payment type meter, a locking spindle a supports strip-like wards c providing a plurality of channels d. A detent e projects into each of a number of. the channels and is formed by an extension of a carrier piece f which is slidably mounted on a screw-threaded rod h rotatable by a knob i in conjunction with a combination device. A gap g is provided in every ward c, each gap being different and complementary in shape to a corresponding detent e. The position of any detent e is indicated by a spring j, one end of which traverses indentation k in the lock case and the other end of which is viewed against a scale of letters or numbers through a panel. In operation, adjustment of the detents e permits the spindle a to be advanced by the equivalent of one channel, after which further rotation of the spindle is prevented until the detents are again adjusted to their appropriate gaps in the wards c. A setting spindle o actuatable by a knob p controls the pre-setting element of the meter and is controlled for rotation in one direction only by a pawl and ratchet q and by the spindle a when that spindle is freed to rotate by the adjustment of the detents e. The drive between the spindles a and o comprises a member s attached to the spindle o which engages a toothed wheel attached to the spindle a. The spindle o is also controlled by a detent t which causes the spindle to be arrested towards the latter part of the pre-setting operation. The detent may be withdrawn manually to permit completion of the pre-setting. In an alternative arrangement, the carriers may be adjusted by means of a suitably warded keyway engageable by a suitably bitted key to effect directly or indirectly the adjustment of the carriers and to maintain a supplementary detent on the locking spindle while key movement is in progress.

Title: Improvements relating to the ventilation of dynamo-electric machines
IPC: H02K5/20
Filed: 1926-12-10
Abstract: 262,808. Allgemeine Elektricitõts Ges. Dec. 10, 1925, [Convention date]. Armatures and field-magnets, cooling and ventilating.-Consists in au arrangement of ducts and separators for directing cooling air or other gaseous medium through the cores of dynamoelectric machines in which the medium enters the core radially from the outer circumference through inlet ducts between packets of the stampings, passes axially through passages and issues from the core radially through other outlet ducts between the stampings, the latter ducts preferably alternating with the former. Separating members are inserted between the packets of laminae such that pocket-like chambers are formed whereby cooling air which enters these pockets in the outlet slots from the air supply passages passes through the axial passages into the adjacent inlet slots, while in the inlet slots at the places where they cross the axial passages a part of the air issuing through the outlet slots passes outwardly after flowing through the corresponding axial cooling passages of the inlet slots. Fig. 1 shows a longitudinal section through a machine on the plane A, B, Fig. 4, and Figs. 3 and 4 respectively are sections on the planes EF, GH, Fig. 1. The medium passes from the end spaces 10 and passages 4 through inlet ducts 5, 5<1> between the packets and, owing to blocking rings 12 adjoining the air-gap, is deflected through axial passages 9 behind the winding slots to the inner parts of outlet ducts 6, 6<1>, whence it emerges from the machine at 11, as shown in Fig. 4. Separators 7 in the outlet ducts shut off a portion of these ducts so that their enclosed portions serve also to deflect some of the incoming medium axially through the passages 8 so as to join that in the inlet ducts 5, as shown in Fig. 1. Similar separators 7, Fig. 3, define pocket-shaped chambers at the outer parts of the inlet ducts such that a portion of the medium flowing radially outwards through the ducts 6, 6<1> from the axial passages 9 is deflected axially through the passages 8 into the enclosed upper parts of the inlet ducts 5 whence it emerges from the machine, as shown at 11, Fig. 3. Thus, each inter-packet duct is completely utilized, partly by incoming and partly by outgoing medium. The outlet ducts 6, 6' are open at the air-gap and the passages 9 may be merged into the winding slots without intervening iron. In place of air, nitrogen, hydrogen, carbonic acid gas or other medium may be used and it may be passed through the machine either by pressure or suction. In an alternative arrangement, the medium may pass along the air-gap instead of or in addition to the passages 9; also the pressure chambers 10 may be transposed to the centre of the machine in place of being at the ends. Specification 16391/13 is referred to.

Patent GB-305310-A (GB)
Title: Improved apparatus for developing photographic prints and the like
IPC: G03D5/06
Filed: 1927-11-24
Abstract: 305,310. Hall, B. J. Nov. 24. 1927. Developing apparatus. - In a machine for developing photographic prints, the development is effected, by the action of two developer carriers impregnated with developer and rubbing in opposite directions on the surface of the print as it travels forward on an endless band. In Fig. 1, the endless band 2 carrying the print passes between adjustable gripping rollers and then under the developer carriers 1, 3 comprising rollers geared together to rotate in opposite directions. The roller 1 is mounted in fixed bearings and the roller 3 in bearings which can be rotated about the axis of the roller 1. At the commencement of the operation the roller 3 is raised above the print, but as the rollers rotate a pawl on the end of an arm 4 by engagement with the gear wheel of the roller 1 causes the roller 3 to be lowered into operative position. When development of the print is completed the roller 3 is again raised by means of an arm 8. The roller 1 moves in the same direction as the band 2 and its peripheral speed is greater than the speed of the band so that the rollers rub the print in opposite directions. In Fig. 3. the roller 3 is replaced by an impregnated pad or damper 9 which is lowered into contact with the band 2. In either form the means shown for lowering the roller 3 or the pad 9 may be replaced by a timing device in the form of a dash-pot. The gripping rollers 5 may be replaced by a single roller over which the band 2 passes. The prints leaving the band 2 are received on an endless band 10, Fig. 5, and passed between said band and an intercepter 11. The band 10 takes up clean water from a tank 12 and passes it over the print. The quantity of water carried by the band may be increased by attaching absorbent members 15 thereto.
