Filed: 1964-08-26
Abstract: 1,019,866. Telegraphy. SIEMENS & HALSKE A.G. Aug. 26, 1964 [Aug. 27, 1963], No. 34856/64. Heading H4P. In a keyboard apparatus in which each key corresponds to two code characters, i.e. upper and lower case, means is provided whereby a code character representing one character on a key is transformed to a character representing the other character by reversing the polarity of certain of the code elements under control of a single transfer key. In an electrical system, Fig. 5 (not shown), depression of a character key causes code bars to Set switches T (a 7-bit code is referred to) which feeds signals via transmission contacts S. All keys in which, to change from the one character to the other, requires contact T3 to be reversed are coupled to group selector switch G2. If then transfer switch U is operated the third element is reversed. Switches G3 and G4 are associated with other keys which require the fourth and fifth elements to be reversed. A mechanical system, Fig. 6, includes code selector bars 1 (only one shown) which selectively places lever 2 to abut stop 3 on lever 4 which, under control of timing cam 6, operates switch 8. If depression of a key also moves group selector bar 10 rightwards, lever 9 is potentially above to abut stop 3, but, spring 13 being stronger than spring 11, it cannot do so until transfer key 14 is operated. Thus when bar 10 is to the right and the key 10 is operated switch 8 cannot be operated whether or not lever 2 is operated.  Other generally similar mechanical systems are described, Figs. 7-10 (not shown), including one in which a single group selector bar 10 is associated with two levers 9 for controlling two elements in a code combination.

Abstract: 1,200,221. Purification of water. CURZON DOBELL. 1 Aug., 1967, No.35178/67. Heading B1B. [Also in Divisions F3 and F4] Potable water is obtained from sea water (or other non-potable water) in reservoir 20 by passing a stream of atmospheric air over briaded-cotton wick plates 22, which are saturated with the sea water, so that the air takes up water-vapour, drawing the moistened air by if an 25 in section 17 where the air is cooled by coils 32, 33 and water-vapour condenses. The condensate .(i.e. potable water) is withdrawn from section 17 through pipe 41 by pump 42, and is received in tank 44. Partially unsaturated atmospheric air enters the apparatus through inlet 19 and is heated in section 15 before it passes over wick plates 22. The air may be heated by the sun, in which case baffle plates 30 are painted black. As shown, the apparatus will float in the sea at level 39; and rudder 45 adjusts its position so that inlet 19 is constantly facing the wind. Air is discharged from the apparatus through outlet 46. Coils 32, 33 may be cooled by feed water which then passes through pipe 36 to reservoir 20. A land-based apparatus is described wherein the air to be heated flows up an annular passage, the external wall of which has annular fins to absorb solar heat.

Abstract: 191,052. Groll, C. Dec. 27, 1921, [Convention date]. Air supply, regulating.-Hinged dampers 22, Fig. 3, connected by a rod 23, are closed by the opening of the furnace door and subsequently opened when the door is closed, being allowed to close gradually under the control of cataract mechanism. The dampers are connected by a chain 24 to a long counterweight 9, Figs. 1 and 2. By opening the furnace door, a chain 1 is operated to raise a slide 2 connected by tackle 6 and a link 21 to the counterweight 9, which is also raised and allows the dampers 22 to close. The cataract bell 7 is raised by a chain 14 and actuates, through a connecting-rod and bell-crank lever 16, a link 17, and thus allows a stepped cam mounted in a frame 11 to be pushed forward by. a balance weight 12 to engage with a projection 10 on a counterweight 4 which rises with the slide 2. Upon closing the door, the slide 2 falls and allows the counterweight 9 to fall and open the dampers 22. The bell of the cataract falls slowly and withdraws the stepped cam from engagement with the projection 10, thus allowing the weight 4 to fall and close the damper by means of the chain 18 and rod 20. The steps of the cam are formed by thin strips which are adjustable to vary the time of closing of the damper.

Abstract: 967,731. Lifting cradles with gripping tines. DIESEL EQUIPMENT Ltd. Oct. 18, 1960 [Oct. 20, 1959], No. 35438/59. Heading B8H. The tines of a lift fork are pivotally mounted on a frame about an axis substantially perpendicular to the tines but spaced from their longitudinal axes so that limited pivotal movement takes place between the tines and the frame when the frame is raised and engages a load, this pivotal movement causing grippers on each tine to be moved towards grippers on an adjacent tine to engage articles between them. As shown in Figs. 1, 4, each tine 12 is hooked over a bar 14 on the frame 10 of a lifting cradle and is provided with a rotatable shaft 30 on which are secured grippers 18 and a lug 28. Plates 22, pivoted at 24 on the tines, are urged in a counterclockwise direction by torsion rods 36, each secured at one end 38 to the shaft 30 and at the other end to the tine 12, so that when there is no load on the tines the plates 22 bear against a beam 16 on the frame 10 with sufficient force to maintain a gap 40, Fig. 4, between the ends of the tines 12 and the beam 16. On raising the lift fork after the tines have been inserted between articles in the bottom layer of a stack, the tines pivot about bar 14 on engaging the next layer, thereby rotating the plates 22 against the action of torsion rods 36 and rotating the shaft 30 to cause the grippers 18 to engage the articles of the bottom layer. In a modification, Fig. 6, the plate 22 and shaft 30 are replaced by a slidable bar 52, mounted on parallel links 53 and provided with gripping pads 66. As the tines engage the load and pivot on the bar 14, the bar 52 is moved longitudinally and at the same time moves laterally to grip the load. In a further modification, Fig. 7 (not shown), a lifting frame is provided at each end of the tines.
