Title: Facsimile transmission systems
IPC: H04N1/409
Filed: 1958-08-08
Abstract: 842,235. Electric signal transmission systems. WESTERN ELECTRIC CO. Inc. Aug. 8, 1958 [Aug. 12, 1957], No. 25496/58. Class 40 (4). In a facsimile transmission system signals derived by scanning at the transmitter are converted into pulses comprising excursions from a first amplitude level to a second amplitude level and means for ensuring that the said excursions are of at least a predetermined duration. This enables the signal to be transmitted over a channel of more limited band-width. In practice, it means that with horizontal scanning thin vertical lines are transmitted as though they were slightly thicker. In one embodiment, Fig. 4 (not shown), the signal is passed through an amplitude slicer and then fed to a flip-flop circuit whose restoration time is equal to the required duration-and is combined with slicer output in an OR circuit whose output is then transmitted. In a second embodiment signals above a certain amplitude cut-off valve 64 of the flip-flop 64, 54 which is maintained in this state for the duration of the input signal if the latter is of duration greater than that prescribed. If this duration is less however, the flip-flop is maintained in this state for the prescribed duration by a time-constant circuit comprising condenser 61 and resistor 62. The output from the anode circuit of 54 is transmitted.

Title: Improvements in materials for refining hydrocarbon oils
IPC: C10G29/06
Filed: 1924-10-27
Abstract: Light hydrocarbons, e.g. gasoline, naphtha, benzine, and kerosene are purified by treating the vapour or hot or cold liquid with a combination or intimate mixture of hydrous aluminium silicate and a metal salt having an affinity for the sulphur compounds.  Basic materials such as caustic soda or other alkali, p  or compounds of magnesium, calcium, barium, or strontium may be added to neutralize acid.  Metals specified are copper, iron, lead, manganese, zinc, or antimony.  Preferably the silicate is impregnated with a solution of the salt in water, alcohol, glycerine, ethylene glycol, or other liquid not readily dissolving or being dissolved by the oil, and the mixture dried.  The Specification as open to inspection under Sect. 91 (3) (a) describes the use of any highly adsorbent inorganic material and a metal or its oxide or salt.  Adsorbents mentioned are hydrous aluminium silicates and zeoltes, e.g. Bentonite, fuller's earth, Green Sands, Permutite, Refinite, Borromite, Henlandite, Phillipsite, Hormatone, Stilbite or Desmine, Laumontite, Chabazite, Analcite, Natrolite, Scolocite, Thomisonite, Pyrophyllite, and the gels produced by treating sodium aluminium silicate or copper aluminium silicate with sulphuric acid.  The most effective combination is obtained by mixing a soluton of a salt with a colloidal clay to a cream or paste, and heating to 250-1200 DEG  F. to drive off the solvent and maybe reduce the salt to oxide or metal. The used material is regenerated by heating to 250-1200 DEG  F.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to change speed gear
IPC: F16H15/04
Filed: 1924-10-27
Abstract: 246,561. Mitchell, A. R. Oct. 27, 1924. Variable-speed friction gearing comprises a flexible disc which is bent at different zones into power-transmitting contact. The gearing, which may be used as a main transmission, is described in its application as an auxiliary to a toothed transmission gearing of the lay-shaft type upon a vehicle to facilitate the engagement of the change wheels. Thus a pair of discs 6, 7, Fig. 4, are feathered upon the main shaft 3 and arranged close to and overlapping a disc 8 mounted on the lav-shaft 5 so as to yield axially. Control rollers 20, 21 are adapted to be pressed selectively against the disc 6 so as to grip the system against an opposed fixed roller 29, the discs 6, 7 yielding against springs 18. Continuous speed variation may be arranged for by having a single control roller or pair of rollers movable in the line of the disc centres. Control of the main gear is effected by rocking a shaft 32, Figs. 2 and 3, and this through cams 30, 31 strikes up the levers 24, 25 alternatively, the control rollers 20, 21 being carried by these levers. To facilitate the deformation of the discs, slots 40, Fig. 1, may be formed in them. Specification 181,057 is referred to.

Title: Improvements in or relating to circuit arrangements for a switching system for use for example in a telephone installation
IPC: H04Q3/00
Filed: 1960-07-22
Abstract: 954,044. Automatic exchange systems. SIEMENS & HALSKE A.G. July 22, 1960 [July 23, 1959], No. 25675/60. Heading H4K. In a switching stage in which the possibility of setting up a connection between any free inlet and an outlet of a particular group is independent of whether connections to outlets of other groups exist, and in which such a connection is set up under control of a marker, use is made of testing networks each arranged to cover only the possibilities of connection between the inlets and a single group of outlets, there being as many such networks as there are different types of outlet group, the networks being connected in common to a first group of wires connectable to the inlets to be served, and the outlets of a wanted group being connectable through a second group of wires to that network which is suitable for the outlet group in question. The switches employed are cross-point matrices, the cross-point contacts not being shown. The inlets 1-k are multipled to the column wires, but the outlet (horizontal) multiple is split. The testing networks Sr, Sq consist of two-input AND gates of which the resistors are common to the gates of Sr and Sq, the first input of each gate being connectable via one of the wires PI to an inlet and the second via one of the wires PII to an inlet to which that outlet may have access. The outlet groups have either r or q (q<r) outlets and the corresponding network Sr or Sq is connected up in each case, The out. put conductors of the network gates are connected to the input terminals of a one-at-a-time selector W which chooses one of the inlets which corresponds to a free path through the stage viz., inlet free and outlet free. This determines the inlet and outlet to be connected together, and the marker sets up the required connection. Thus to set up a connection to an outlet of the second row of switch B31 the contacts 311-31k are closed to connect the wires PI to the inlets of B31, contacts 3121-312q to connect PII to the second row outlets, and contacts 123- (k-2)(k-1)k to connect up Sq. Free inlets have negative free potential thereon, and busy outlets positive busy potential. As resistances Z1-Zk have higher values than the forward resistances of G1q-Gkq the busy potential overrides the free potential, so that negative free potential appears only at those inlets of W which correspond to free inlets and free outlets. One such inlet is chosen by the selector W and the connection is set up by the marker (not shown). Specifications 904,463 and 945,357 are referred to.

IPC: F01D11/02
Filed: 1968-05-30
Abstract: 1,174,207. Turbines; gas turbine plant. ROLLS-ROYCE Ltd. May 30, 1968, No.25922/68. Headings F1G and F1T. [Also in Divisions F2 and G3] Apparatus for controlling the axial gap between a fixed structure and an axially movable rotatable structure of a fluid-flow machine comprises fluidpressure means responsive to changes in a supply pressure and controlling a power source capable of producing relative axial movement between the fixed and rotatable structures, the supply pressure being fed to the fluid-pressure means from a chamber bounded by the structures via an orifice which is closable by a part of the rotatable structure so as to vary the supply pressure in dependence on the size of the gap. When applied to a gas turbine engine to maintain constant the axial clearance "A" between the tips of the turbine rotor blades 22 and part of the housing 21, the invention includes a chamber 20 bounded by a heat shield 18 and pressurized by air from the engine compressor. Axial and radially extending seals 30, 32 maintain the air pressure in chamber 20. An annular flange 26 on an extension 28 of the turbine disc 10 co-operates with a pad 34 secured to heat shield 18, the size of the axial gap between the flange and pad determining the rate of leak-off of air from chamber 20 to a duct 36, 38 and hence the pressure in the duct. The latter is connected to a chamber 40 on one side of a spring loaded diaphragm 44 attached to a spool valve 50 slidable in a bore 52 in a housing 54. A hydraulic pump 68 supplies fluid through a pipe 70 to an inlet port 60 of the bore 52 and, according to the position of spool valve 50, the fluid may pass to one or other of pipes 74, 76, leading to opposite sides of an annular piston 78 slidable in a fixed cylinder 80. The piston 78 is attached to the outer race 82 of a bearing 84, the inner race 86 of which is mounted on the shaft 14 connecting the turbine 10 to the high-pressure compressor (6, Fig.1, not shown), of the engine. Thus any change in pressure in duct 38 as a result of a departure from the desired value of the axial gap causes adjustment of the spool valve 50 and axial movement of bearing 84 and shaft 14 to restore the gap to its desired value. In a modification, the piston 78 is fixed and cylinder 80 movable and attached to shaft 14.
