In Fig. 1 the first turbine 1 is connected to drive an air compressor, not shown, and the gases discharging from the turbine 1 are directed on to a second turbine 5 mounted on a shaft 6, the shaft 6 being connected to shaft 21 which in turn is connected through gearing 23, 24 to shaft 22 by which the helicopter rotor is driven. The gases discharging from the turbine 5 pass through a duct 11 which divides into two passages 12, 13, the gas flow through the inner passage 13 being directed by guide vanes 20 on to turbine blades 18 which thus drive fan blades 17 mounted on a rotor 16. The fan blades 17 are disposed in annular duct 9 and the air impelled by the fan blades is discharged through " cold " propulsion nozzle 10. The hot gases passing through the outer duct 12 by-pass the turbine 18 and discharge through a " hot " propulsion nozzle, the cross-sectional area of which is controlled by pivoted flaps 19, the flaps thus serving to control the proportions of hot gases which pass through the turbine 18 and the by-pass passage 12. Control flaps may alternatively be provided as indicated at 24. In a second embodiment, Fig. 2, the turbine 26 drives the helicopter rotor, the gases from the turbine 26 passing through two ducts 33, 34, the gases passing through the inner duct 34 being guided by vanes 36 on to turbine rotor blades 37, the turbine being connected through shaft 38 to drive ducted fan 39. The fan takes in air through inlet 41 and discharges it through " cold " propulsion nozzle 42A. The gases passing through the outer duct 33 by-pass the turbine 37 and discharge together with the exhaust gases from the turbine 37 through hot propulsion nozzle 31. Control flaps 47 are provided to control the proportions of gases passing through the turbine 37 and the by-pass passage 29.

Title: Improvements in or relating to machines for operating on sheets of cardboard or the like presented to operating parts thereof by hand
Inventor: GIBSON GEORGE WILLIAM
IPC: B65H3/38
Filed: 1959-01-19
Abstract: 938,315. Feeding sheets. BRITISH UNITED SHOE MACHINERY CO. Ltd. Jan. 15, 1960 [Jan. 19, 1959], No. 1819/59. Class 100 (1). In apparatus for lifting sheets by a suction member from a pile so that they can be presented by hand to a machine for operating on them, the sucker is reciprocated to and fro by a drive from the machine and yieldingly engage the top sheet so as to accommodate themselves to the level of the pile. A box-making machine of the type described in Specification 762,502 comprises gluing means 30, means 40 for folding end portions of the box after application of glue thereto and means comprising a vertically reciprocable late 50 and an abutment 82 between which an end of a box blank is pressed after gluing and folding. The operator holds each blank while it is being worked upon by the machine, taking the blanks one at a time from a pile 102 on a shelf 100. A rubber cup 106 is supported above the pile 102 by a rod 110 carried by an arm 112 which is fixed to a pin 114. The pin 114 is journalled in a bracket 116 fixed to the machine frame and carries a second arm 118. One end of a rod 120 is slidable in a hole in the arm 118, such sliding movement being limited by collars 124 and a spring 126. At the other end the rod 120 is pivoted to a lug projecting from the plate 50. Thus each time the plate 50 moves upwards the cup 106 is pressed down on to the top blank of the pile 102 with enough force to enable it to grasp the blank by suction. When the plate 50 moves downwards the cup 106 raises the top blank to the position shown, where it may easily be grasped by the operator; Variations in the height of the pile 102 are compensated for by the resilient connection between the arm 118 and the rod 120.

Abstract: 1499902 Optical brightener and filler DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT and HENKEL & CIE GmbH 16 Jan 1975 [17 Jan 1974] 1869/75 Heading D1P A dry, pulverulent composition contains an optical brightener and a finely divided (max particle size 0.1mm) water - insoluble alumino- or boro-silicate having a calcium binding capacity of at least 50mg CaO/g of anhydrous silicate (=AS), and of general formula;  wherein Cat represents a cation exchangeable with calcium and of valency n, x represents a number from 0.7 to 1.5, M represents boron or aluminium and y represents a number from 0.8 to 6. The exchangeable cation may be hydrogen, lithium, potassium, ammonium or magnesium or the cation of a water soluble organic base, but is preferably sodium. The brightener may be substantive to cotton, polyamide or polyester, and may be a diaminostilbenedisulphonic acid, diarylpyrazoline carbostyril, 1, 2 - di(2 - benzoxazolyl) - or 1, 2 - di - (2 - benzimideazolyl) - ethylene, benzoxazolylthiophene, coumarin or distryryldiphenyl derivative. The composition may be formed by hot - drying e.g. by unitary spray or rollers, a slurry of the components. In a modification, the silicate is formed, e.g. by admixture of sodium aluminate and sodium silicate, in aqueous suspension in the presence of the brightener, which is thus coated with the silicate upon drying. Hollow beads may thus be formed. The silicate may be amorphous or microcrystalline. Other water-soluble or finely divided water-insoluble inert substances may also be present.

Abstract: 1,237,843. Roller conveyers. TRANSPORTMECHANIK WITTENBERG VEB. 14 Jan., 1970, No. 1876/70. Heading B8A. A roller conveyer comprises double-armed levers 7 pivotally supported at 9 and pivotally carrying at one end a lever 6 on which a pair of rollers 2 is mounted. At the other end of the lever 7 a further roller 2 is carried. For driving the rollers 2, a belt 3 is supported on rollers 4, 5, but the rollers 4 may be replaced by a slide plate (11), Fig. 4 (not shown). At each end of the conveyer are additional driven rollers 15 together with an idler roller 16. Each end also includes means for stopping articles comprising arms 12 and a pressure roller 12a which are operated by a ram 13. Assuming the stop means is operative, Fig. 6, an upstream accumulation of articles is supported on the rollers 2, but the rollers are undriven since the length of each article is such that the double-armed levers 7 are in balance and the rollers 2 do not engage the belt 3. When the stop 12 is lowered the pressure roller 12a raises the belt 3 into engagement with the adjacent rollers 2 and the leading article is moved forwardly. The balance of the lever 7 supporting the second article is thus disturbed and the pair of rollers 2 mounted on the lever 6 engage the belt, thus causing the second article to move downstream. Succeeding articles are similarly moved. The belt 3 can be driven forwardly or rearwardly.

Title: Process for the conversion of gases which contain resinifying substances
Inventor: KROME HELMUT
IPC: C01B3/16
Filed: 1964-01-16
Abstract: A process for the catalytic reaction of gases containing CO and resin-forming substances with steam to form CO2 and H2 comprises passing the gases with steam at a temperature above 450 DEG  C. over a layer of catalyst containing iron oxide and chromium oxide, cooling the gases to a temperature favourable for the CO-conversion step, e.g. 340 DEG  to 400 DEG  C., and carrying out a conventional catalytic CO-conversion step with steam on the gases. The preferred temperature for the first catalytic reaction, which is a hydrogenation and partial conversion reaction, is 470 DEG  to 520 DEG C., and 20% to 40% by weight of the total catalyst is used in the first layer.  The second catalyst may be the same material as the first, or may contain copper and/or molybdenum. In a specific embodiment, gas at 900 DEG  C. obtained by cracking liquid hydrocarbons is the feedstock, and is passed in series through two waste heat boilers between which the first catalytic reactor is located.  The process may be carried out at atmospheric or superatmospheric pressure, and the process may be applied to coke oven and producer gas.

Title: Improvements in and relating to electro-optical switches
IPC: H05B39/08
Filed: 1935-01-21
Abstract: 450,844. Control systems for incandescent lamps. GEFFCKEN, H., 9, K÷nig- Albert-Strasse, Naunhof, near Leipsic, and RICHTER, H., 3, Wiederitzscherstrasse, Leipsic, Germany. Jan. 21, 1935, No. 2024. Convention date, Jan. 20, 1934. [Class 38 (iv)] [See also Group XL] In photocell apparatus for switching lamps on at night and off in the morning, the sensitivity is changed at each operation so that switching-off is effected at a lesser strength of daylight than that by which switching- on is effected ; and delay mechanism is provided to prevent the occurrence of hunting. The change may be produced by an alteration of circuits or by interposition of screens before the photocell. In the arrangement shown in Fig. 1, in which the lamp-controlling relay 5 is controlled through a valve 4 by a photocell 1, the parts 2 and 3 being resistances, the sensitivity is altered by switches 6 and 8 under the control of a delay-producing mechanism 9 utilizing a wiper contact or a thermal or electrostatic timing-device. In the arrangement shown in Fig. 2, the pendulum 20, which turns the lamp on and off by means not shown, closes contacts 16 in one position and contacts 15 in another ; in this way it controls the connections of a bridge of which the valve 4 and relay 12 are members, and so determines the sensitiveness of the relay. When the illumination of the photocell 1 increases in the morning, relay 12 causes relay 18 to move the pendulum 20 into the position shown, switching off the lamps. At the same time it closes contact 16 and opens contact 15, so as to alter the balance of the bridge and decrease the sensitivity of the device. This change of sensitivity causes relay 12 to reverse and pendulum 20 to be released, coil 17 being now energized instead of coil 18. But the latter now engages the toothed wheel 23 and holds it until the daylight has increased sufficiently to re-energize the relay 18 at the new threshold of sensitivity. The wheel 23 then revolves until a stop 26 carried by it engages a tooth 25 on the pendulum 20. A similar process in the reverse sense takes place at night. Fluctuation of the illumination during the rotation of the wheel 23 causes the pendulum 20 to fall back and lock the wheel temporarily.
