Title: Improvements in or relating to venetian blind operating mechanism
IPC: E06B9/308
Filed: 1950-05-05
Abstract: 670,931. Venetian blinds. ROLLADENFABRIK A. GRIESSER AKT.-GES. May, 5, 1950 [May 6, 1949; Dec. 1, 1949; April 19, 1950], No. 11227/50. Class 20(iii) An operating mechanism for a venetian blind .in which the slats are raised or lowered by cords engaging pulleys on a winding shaft comprises a device which allows rotation of the shaft in either direction to adjust the height of the blind but prevents rotation of the shaft, when the drive is removed, by the weight of the blind, which thus remains in any set position. In the form shown, the mechanism consists of a shaft 2, rotatable in bearings 3 and 4 and carrying pulleys 5 for the lifting cords 6. Between and at each side of the pulleys a tube divided into three parts 15, 16, 17 is mounted on the shaft 2, the ladder tapes 11 of the blind being attached to each side of brackets 14 which connect the parts of the tube. The brackets 14 can be tilted to one side or the other by pulling cords 43 thus allowing the tilt of the slats 10 to be adjusted. The driving end of shaft 2 enters a gear box 20 and engages a shaft carrying a gear 21 which meshes with a gear 23 formed with a skirt portion 24 journalled in a fixed sleeve 25. The gear 23 can be rotated by a sleeve 29 which contacts a driving sleeve 27 pinned to the skirt 24 of gear 23.

Title: Method of and machine for agglomerating pulverulent materials
IPC: B30B11/12
Filed: 1934-04-14
Abstract: 441,328. Coldng-plant. ROBERT, P., 6, Rue de Madrid, Paris. April 14, 1934, No. 11291. Convention date, April 15, 1933. [Class 55 (i)] [See also Group V] In a method of agglomerating pulverulent materials which become pasty and give off gases or vapours under the action of heat, the material is charged and compressed into a container which is then closed and moved along a closed path while being subjected to heat and further pressure, the gases evolved by the material being permitted to escape from the container. Apparatus for carrying out the method comprises a rotary drum with peripheral mould pockets furnished with cam-actuated radial compression pistons and with perforations leading to collecting-means for the evolved vapours, a hollow duct for supplying heating- gases which are isolated from the evolved gaseous products, and means for charging the pockets and applying a preliminary pressure thereto. In the form shown, a drum carrying radial mould pockets in its periphery is rotated intermittently by a hand-spike 11<a> inserted in turn into one or other of the pockets, so that the rows of moulds are brought in succession beneath the charging-orifices 10 in the plate 5. A plate 3 is reciprocated so that holes 4 therein communicate alternately with the hopper 1 and orifices 10. Rams 13 mounted on pivoted counterweighted arms 14 apply a preliminary pressure to the loaded moulds while the holes 4 and 10 remain in register. Radial pistons 18, forming the bottoms of the mould pockets, are operated by a stationary cam 20 to compress the material against the inner wall of the outer casing and afterwards to eject the moulded product on to a receiver 41. The cam 20 is formed as a perforated hollow member to distribute heated gas to heat the interior of the apparatus and thus heat the material by conduction through the mould walls, the gases being led into and evacuated from the apparatus through headers at each end of the main casing. The gases or vapours evolved escape through perforations in the moulds to filtering-appliances 35 in the casing leading to a common collecting-duct 37 with or without suction so that the gases may be recovered as a by-product. The filtering appliances may be made of a number of sheets separated by spacers. The spacers may be formed by the burred edges of perforations formed in the plates. Fig. 5 shows a modified apparatus in which the feed hopper 1 is situated inside the ring of moulds, and the pistons 13 for applying preliminary pressure are inside the hopper. The pressure pistons 19 work radially inwards instead of outwards, and are operated by the cam-shaped outer ring 20. Both the outer casing and the mould carrier may be continually cleaned during the moulding operation.

Patent GB-115660-A (GB)
IPC: G07D11/00
Abstract: 115,660. Morris, H. A. April 17, 1917. Money-delivering apparatus.-A machine for paying out wages &c. comprises a reciprocating carriage carrying a keyboard and pushing pieces for actuating coin &c. ejecting slides which pass through slots in tubes containing the coin &c. The carriage 17 is reciprocated on rails 18 or in grooves behind the tubes 1, 2, respectively containing copper and silver coins, by a handle 12 which operates through bevel gear a shaft 13 having crank-pins 15 at each end engaging forks &c. 16 on the carriage. The machine comprises two keyboards, controlling the issue of silver and copper coins respectively. Notes doubled over thin bars are ejected from columns 3, 4, and the arrangement is such that the delivery of onepound notes may be controlled from the silvercoin keyboard, and that of the ten-shilling notes from the copper coin keyboard. A series of vertically-movable push-bars 19, Figs. 4 and 8, is mounted beneath each keyboard, each bar being provided on its underside with one or more projecting parts 19' adapted to engage projections 9 on corresponding coin-ejecting slides 10 when the carriage is reciprocated, the slides being returned by the engagement of a bar on the carriage with other projections 11 on the slides. The upper side of the bars is provided with holes into which at intervals are screwed pins 191, so that when a lever 20 is depressed, corresponding push-bars are moved into position to engage the required coinejector. By varying the position of the pins, the combination of coins making up the sum required may be altered. Each keyboard has two sets of keys 23, 24. After a key 23 is actuated, the depressed lever 20 is locked in position by a rotating tappet 25 until the carriage, on moving back after ejecting the coins, brings the tappet in contact with a knuckle-hinged restoring flap 32. If a key 24 is actuated, a lever 21 is depressed along with the lever 20, to which it is knuckle-hinged, and, in addition to depressing push-bars 19, it depresses a bar 30 which actuates the push-piece 31 of the note-ejecting slide through levers 27, 29 and a rod 28. Both note-ejectors may be actuated simultaneously by depressing a link 30<a> loosely pivoted to each bar 30. Either push-piece 31 may be put out of action by removing the rod 28, and then may be worked by hand. A record is obtained on a strip of paper drawn between two plates 20<b> by rollers actuated through ratchet or other mechanism at each movement of the keys, the paper being perforated by spring-controlled pins 20<a> depressed by the levers 20. The coin tubes fit removably in sockets and are provided at the lower end with a slide which is withdrawn when the tube is in position. A dummy, which is attached to a curved withdrawinn rod thicker than an ordinary coin, rests on the top of the pile of coins in the tube, and, when these are all ejected, stops the machine. The coins fall into a hopper 7 with sloping sides 8. In a form described in the Provisional Specification, the keys are secured to vertically movable plates cut away so as to engage, each in a different manner, with longitudinal movable boards.

Title: Method of forming an epitaxial semiconductor layer with smooth surface
IPC: H01L21/208
Filed: 1972-03-13
Abstract: 1373673 Semiconductors by liquid epitaxy R C A CORPORATION 13 March 1972 [21 June 1971] 11569/72 Heading B1S A smooth surfaced epitaxial layer of a semiconductor material is produced on a substrate by bringing a surface of the substrate into contact with a solution of the semiconductor in a molten metallic solvent and cooling to deposit an epitaxial layer on the surface, and while the layer is still covered with a film of said first solution bringing it into contact with a second solution of the same molten metallic solvent saturated with the same semiconductor and also containing an additional metal which increases the surface cohesion of the second solution and finally removing the coated substrate from the second solutionwithout retaining any of the second solution on the epitaxial layer. The process may be used to deposit a layer of gallium arsenide containing if desired, a dopant upon a gallium arsenide substrate, in which case the solvent metal may be gallium. The metal used to increase the surface adhesion of the second solution may be aluminium or tin. In a particular embodiment a furnace boat 12 of inert refractory material such as graphite is formed with wells 14, 16-18 and provided with a slide 22 of the same material moving in a passage 20 in the boat 12. The slide has a recess 24 into which a substrate of gallium arsenide 26 is placed. A solution of gallium arsenide in gallium and containing dopants (tin, tellurium, silicon or zinc, germanium, magnesium) is placed in well 14 and a solution of gallium arsenide and either tin or aluminium in gallium is placed in well 16. The boat is heated in a flow of hydrogen to ensure complete solution and cooled while the slide is moved so that the substrate is in contact with the solution in well 14, thus depositing an epitaxial layer of gallium arsenide on the substrate. On moving the slide further in the direction of the arrow a thin film of the first solution is carried along on the deposited layer. When this comes into contact with the solution in well 16, the film of first solution dissolves in the solution in well 16. This takes place rapidly (in a few seconds) and on moving the slide out of contact with well 16 the high surface cohesion of the second solution ensures its total retention in the well and effectively the liquid layer from 14 is scraped off the surface of the epitaxial deposit, so that on reaching well 18 a smooth surfaced layer is found on the substrate.
