Title: Improvements in or relating to printing presses
IPC: B65H1/14
Filed: 1922-07-27
Abstract: 184,174. American Type Founders Co., (Assignees of Kelly, W. M.). Aug. 6, 1921, [Convention date]. Pile tables and supports for sheet-feeds.- Sheets are fed to printing-presses from a pilewhich may be raised by automatic mechanism controlled by the height of the pile, or the pile can be raised independently as desired by manual devices operating through a one-way clutch and gearing so arranged that the friction of the gearing is normally sufficient to hold the table in its raised position, but is not sufficient to do so if the hand-wheel which operates the raising worm is spun in a reverse direction. As shown the pile table 10 is supported by vertically guided brackets 11 carried by chains 16 passing over sprockets 15, the loose ends of the chains depending from the sprockets and being held by members 17. The sprockets 15 are mounted on a shaft 14 geared to a shaft 18, which is capable of being operated automatically or by hand. The automatic means comprise a ratchet 22 operated by a pawl 27 on an arm 21 freely mounted about shaft 18 and oscillated in unison with a camoperated arm 24 by means of a link 26. A pawl 29 prevents backward motion of ratchet 22. The raising means may be held out of action when the pile is at the required height by a pin 47 on a lever 45 controlled by a feeler 41 on an arm 39 connected to a shaft 38. The shaft 38 transmits its motion to the lever 45 via lever and link mechanism 43, 41, 46, Fig. 1, and the pin 47 acts on a pin 48 on link 26 and prevents the action of the arm 21 when the pile is sufficiently high. The shaft 18 may also be operated as desired by a worm 52 on a hand-operated shaft 53 and a worm-wheel 49 which drives shaft 18 through a uni-directional roller clutch. Or the shaft 18 may be driven directly by a crank 56 which can be moved axially to cause a notch 57 to engage a bevelled tooth 58 on the wheel 49. The automatic drive may be put out of action when desired by engaging a pivoted plate 31 by a catch 34. This plate raises the pawl 27 out of action by acting on a pin 37 on the pawl, and the locking pawl 29 is also raised out of action by a circular aperture 32 on a pin 33, the aperture being of such a size as to allow of the normal motion of pawl 29. It is stated that the pitch of worm 52 is such that when the pawl 29 is out of action the friction between the worm and wheel is sufficient to hold the table, but if the wheel on shaft 53 is spun in a reversed direction the friction is not sufficient to hold the table.

Filed: 1966-05-10
Abstract: 1303801 Demagnetizing ships GERMANY MINISTER OF DEFENCE 10 May 1966 [28 July 1965] 20761/66 Heading B7S [Also in Division H1] A ferromagnetic floating body, e.g., a steel ship, is demagnetized by passing along and in the direct vicinity of the body a multi-dimensional loop system adapted to produce vibratory magnetic fields, and if necessary additional constant magnetic fields superimposed thereon, in three Cartesian co-ordinate directions. Preferably two loop systems are mounted in a vertically adjustable manner on two floats which are moved in synchronism, one to port and one to starboard, along the floating body. Mounted on each float 1, as shown in Fig. 1, are a Y-coil 2, an X-coil 3, a Z-coil 4, a braking winch 5, a guide roller 6 for the braking cable, and rollers 7 for enabling the float to move along the hull without damage. By means of a hauling winch and hauling cables to which are secured current supply cables, which hang from cable-carrier floats, the floats 1 are moved along a ship against the braking effect of the winch 5, which effect is transmitted through a braking line fixed at one end to the ship. The floats are kept as close as possible to the hull by the pull-in action of connecting cables which are fitted between the floats and hang below the ship. Alternating current or pulsating direct current is fed into any or all of the coils to produce vibratory fields. There may be superimposed upon, for example, a horizontally acting vibratory field, a constant field for compensating the horizontally acting component of the earth's field. The speed of the floats is regulated to suit the magnetic characteristics of the ship, which are ascertained beforehand. By controlling the speed, it is possible to cause the vibratory fields produced to operate for an appropriate length of time at those points that are particularly heavily magnetized.

Title: Gas turbine engine fuel systems
Inventor: YOUNG JOHN MICHAEL CRISPIN
IPC: F02C7/22
Filed: 1961-06-12
Abstract: 975,916. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 5, 1962 [June 12, 1961], No. 21088/61. Heading F1G. A fuel system for a gas turbine engine comprises a pump, the output of which is dependent solely upon its speed, a throttle valve through which fuel from the pump can be supplied to the engine, a branch passage through which fuel can be spilled from the upstream side of the throttle valve, a centrifugally operable valve for at least in part controlling the spill through the branch passage, and a balancing valve for establishing a pre-determined relationship between the pressure at the downstream side of the throttle and the pressure in the branch pipe. In the embodiment shown there is provided an engine-driven gear pump 1 which supplies fuel through a line containing a throttle valve 2, a shut-off valve 3 and a pressurising valve 4 to a line 5 leading to the fuel burners. A line 6 leads to burners used at starting. A branch passage 7 leads from a point between the pump 1 and the throttle valve 2 and fuel may pass therethrough back to the suction side of the pump. Fuel in the passage 7 enters a bore 11 and discharges therefrom through spill ports 12 the effective area of the ports being controlled by a centrifugallyoperable valve member 10. The fuel spilling through the ports 12 passes to a balancing valve 9 which comprises a cylinder having disposed therein a piston valve 17 the position of which controls the area of a spill port 19. The lower side of the piston valve communicates with the fuel supply line between the throttle valve 2 and the pressurising valve 4 so that the piston 17 takes up a position dependent on the difference in pressure between that downstream of the throttle valve 2 and that downstream of the centrifugally-operable valve 8. An adjustable orifice 12a is disposed in parallel flow with the spill ports 12. The centrifugally-operable valve member 10 is acted on by a pair of centrifugal weights 13 mounted on a rotor 14, the weights acting on the valve member in opposition to a spring 15. The loading of the spring 15 is controlled by the position of the throttle valve 2 so as to increase with increasing throttle opening. A relief valve 1a is provided at the pump discharge. A check valve 20 may be disposed between the valve 8 and the balancing valve 9, a by-pass passage with a variable restriction 21 being disposed across the valve.
Patent GB-889732-A (GB)
Title: Improvements in synthetic rubber latex
IPC: C08L29/10
Filed: 1960-06-16
Abstract: The size of the dispersed polymer particles in a butadiene polymer synthetic rubber latex is increased by adding to the latex a polyvinyl methyl ether the cross-linking of which has been increased by heating before its addition to the latex.  The cross-linking is measured by the decrease in the amount of n-heptane necessary to precipitate the ether from its benzene solution.  The expression "butadiene polymer synthetic rubber latex" means an aqueous emulsion polymerizate of butadiene, isoprene, 2,3-dimethylbutadiene, piperylene, their mixtures, or their mixtures with styrene, vinyl toluene, alpha methyl styrene, chlorostyrene, dichlorostyrene, vinyl naphthalene, acrylic acid, methyl acrylate, methyl methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, 2-vinyl pyridine, 2-methyl-5-vinyl pyridine, methyl vinyl ketone and vinylidene chloride.  An alkali salt electrolyte may also be present, e.g. in amounts up to 2%, the percentage of treated ether being up to 1%, thus raising the solids content of the latex from 20 to 50% to 60 to 70%.  Specifications 859,699 and 889,731 are referred to.

Title: Improvements in methods of producing semi-conductor arrangements
IPC: H01L29/00
Filed: 1961-06-13
Abstract: 923,801. Coating with metals; coating by vapour dep sition. SIEMENS & HALSKE A.G. June 13, 1961 [June 13, 1960], No. 21279/61. Class 82. [Also in Group XXXVI] A PN junction is made by deposition of semi-conductor material on a substrate in two stages from a gaseous mixture containing a decomposable compound of the semi-conductor and, in the first stage a donor (acceptor) impurity to form an N(P) layer, and in the second stage an acceptor (donor) impurity to form a P(N) layer. The layers are each less than 500 thick and the impurities and the temperature of the substrate and rate of deposition in the second stage are so selected that the density of the minority impurity at the side of each region remove from the PN junction resulting from interfacial diffusion is not more than half the density of the same impurity in the other region. A tunnel diode is made in the apparatus shown in Fig. 1 using a monocrystalline silicon substrate 1 on a monocrystalline semi-conductor support 4. The wafer 1 is etch polished and then purified in the chamber by evaporation or surface blasting in a protective gas such as hydrogen or in vacuo. In the first deposition stage silico-chloroform or silicon tetrachloride and hydrogen are introduced into the chamber with a decomposable compound of a donor and a degenerate N type zone 500  thick deposited with the substrate at 1100 C. In the next stage with the substrate at 1000 C. a second more lightly doped (5 Î 10<SP>19</SP> donors/c.c.) but degenerate N zone 100  thick is formed, the deposition rate being controlled at a low value by addition of an inhibitor such as hydrogenchloride or a diluent such as hydrogen to the gaseous mixture. In this step the donor is obtained by suddenly heating coil 11 containing donor impurity. In a third stage a similarly doped P-type zone 100  thick is deposited including acceptor material obtained by suddenly heating coil 12 containing it. The doping materials such as BrP are therefore vapour deposited from heaters 11 and 12. The substrate is maintained at 1000 C. during this stage and the deposition rate is rapid. As a result, diffusion between the second and third layers is minimized. Subsequently, a fourth more heavily doped P zone 2000  thick is deposited with the substrate at 950 C., the deposition rate being maintained at the maximum consistent with obtaining monocrystalline material by removal of inhibitor and diluent gases. A rapid flow of the gas, which is preferably preheated, is maintained throughout the process, the inpurities being thoroughly mixed with the gases by the turbulent flow through vanes 10. If the silicon substrate is replaced by one of metal this forms one electrode of the device, a second being then formed on the fourth zone by deposition from a decomposable metal compound. Use of silane or germane in the above process permits the use of lower substrate temperatures with a consequent reduction in diffusion. Metals may also be deposited by vapour deposition to form required contacts.
