Title: Programmecontrolled data processing systems
IPC: H04L12/52
Filed: 1972-01-14
Abstract: 1347453 Automatic exchange systems; telegraph exchanges SIEMENS AG 14 Jan 1972 [12 Feb 1971] 1828/72 Headings H4K and H4P In a programme controlled exchange in which digital data on an incoming feeder is entered into a storage cell allotted to that feeder prior to its onward transmission to a particular trunk identified by a word retained in the storage cell, modification of the stored data may be effected by the use of a temporarily allotted information converter which is connected to the store in the same manner as a feeder and a trunk. The converter may be a code changer or a distortion correction device. The store is of the core type. The substations Tn are arranged in groups each having a terminal equipment SA. Each substation has an incoming feeder and an outgoing trunk which have appearances on an input code converter ECW and an output code converter ACW that serve to buffer a central store KS to the substations. On a normal call, dialled information from substation Tn1 say, is labelled, in ECW, with its station's identity B so that the programme control may seize a storage location SZw in KS allotted to Tn1 and to write therein the identity A of the called line say Tn2 and also to write Tn1's indentity into the location SZv allotted to Tn2 so that a duplex connection therebetween may be effected. If the control decides that the call requires the use of additional equipment, it seizes two converters say E1, Em which have appearances on ECW and ACW exactly analogous to ordinary feeders and trunks. It then replaces or supplements the identity A of Tn2 in SZw with the identity of E1 and in the latter's storage location SZu it inserts the identity A of Tn2 so that further data emanating from Tn1 is modified by E prior to its transmission to Tn2. Converter Em is utilized in the same manner for data passing in the opposite direction.

Abstract: 1418724 Cartridge actuated fastener driving tools GUNNEBO BRUKS AB 15 Jan 1973 [4 April 1972] 2011/73 Heading B4C The cartridge magazine in a fastener driving tool comprises a storage means for cartridges and a feed channel which is movable from an operative position to permit a cartridge to be fed into the cartridge chamber to a non- operative position clear of the cartridge chamber to permit firing and discharge of the spent cartridge. As shown in Fig. 1, the cartridges 2 are held in a tubular magazine 4 which is filled through a removable screwcap 14. A cartridge is loaded into the chamber 3 by gravity after the barrel 7 has been pulled out to the position shown and inclined downwards at the same time as the magazine is rocked by hand about a pivot 11 against the action of a spring 13 from the raised non-operative position shown in broken lines. The cartridges may be stored instead in a rotary cylinder 17, Fig. 2. In another embodiment, Figs. 3 and 4 (not shown), the cartridges are stored in a rotary magazine cylinder (22) mounted at the side of the tool in a bracket (23) which permits the magazine to be pivoted against the action of a spring (25) into its operative position where a cartridge can be loaded directly into the chamber (3) under gravity when the tool is inclined downwardly. In a further embodiment, Figs. 5 and 6 (not shown), a tube similar to that of Fig. 1 is employed. The open end of the tube is covered by a leaf spring (31) which is held in an inoperative position during the movement of the tube into its loading position. In a still further embodiment, Fig. 7 (not shown), a rotary magazine cylinder (17) is mounted in a fixed position on the tool and feeds a tube (20) which can be pivoted about a pin (37) against the action of a spring (39) into the loading position. In the embodiments the cartridges may be pushed along the tube by a spring. Fasteners to be fired are inserted into the mouthpiece 16 of the tool.

Abstract: 390,287. Reversing- gearing. SOLTER. BECK, O., Meiendorf, Rahlstedt, near Hamburg, Germany. Jan. 25, 1932, No. 2250. [Class 80 (ii).] In reversing-gearing the reversed drive is effected through a crank linkage in which a pair of driving-cranks f, g are connected to a pair of driven cranks h, i through four pairs of connecting-rods, each pair connected to one of four crossheads l, Figs. 1 and 2, sliding on the four arms of a guide in the form of a cross k<1>, k<2> secured inside a casing c loose upon driving and driven shafts a, b, which carry crank discs e<1>, e2 corresponding. The reversed drive is effective when the casing c is held fast by a coil brake n applied to a casing extension m. The forward drive is a solid one obtained by engaging a plate clutch x connecting the casing m to the driven shaft b. Control is effected by a lever r connected both to a pivoted wedge q and to a clutch cone s<1> splined on a sleeve c<1> rigid with the casing m. When the lever r is moved to the right of Fig. 1, the wedge q engages between scissor levers (not shown), which engage the coil n. Movement of the lever r to the left engages the cone s<1> with a loose cone s<2> carrying centrifugal levers t which through a sleeve u, levers v, and pins w effects the engagement of the clutch x. An arrangement of links pivoted to the casing equivalent to and in place of the cross guide is described. Eccentrics may replace the cranks.

The solid particles may be a nickeliferous matte, in which case, Ni values (as chloride) are leached preferentially from Cu and precious metals. The leach solution may contain copper which may be removed as sulphide by adding to the agitated leach solution, e.g., Ni 3 S 2  in the form of a nickeliferous matte and elemental S. The leach residue which contains precious metals may be treated for their recovery with aqua regia.

Title: Improvements in or relating to television and the like systems
IPC: H04N3/02
Filed: 1936-01-25
Abstract: 469,427. Optical systems. SCOPHONY, Ltd., and JEFFREE, J. H. Jan. 25, 1936, No. 2392. [Class 97 (i)] [Also in Group XL] From a light-source 4 an intermediate beam 9 is produced which has a larger convergence in one plane than in a perpendicular plane and is converted to an emergent beam with a dimension in one direction which is smaller than any dimension of the source of light. The light from the source has a relatively large light grasp in the two mutually perpendicular planes and the emergent beam has a relatively small light grasp in the direction of its smaller dimension and a relatively large light grasp in a perpendicular direction. The light grasp is the product of the width of the exit pupil and the angle of divergence of the beam, as described in Specification 433,945, and the total light grasp of a beam remains constant in the absence of stops or screens. The emergent beam is parallel in its smallest dimension but diverges in planes at right angles to that dimension. The intermediate beam is produced by a spherical lens 5 and, a cylindrical lens 6 or mirror in co-operation. The intermediate wedge-shaped beam is projected on a plurality of reflecting steps 8, each of which rotates the incident elemental wedgeshaped portion 10 through 90. The steps consist of staggered right-angled prisms 7a . . 7z with their parallel opposed surfaces contiguous. Alternatively, two sets of reflecting laminae with their parallel opposed major surfaces contiguous have their edges staggered to form staircases, the mean planes of which are relatively inclined, as described in Specification 469,426. The apparatus is used in a television receiver to obtain a flat beam of light to pass through the light-valve described in Specification 439,236.

Abstract: 710,579. Axial-flow blowers and turbines. DEMAG AKT.-GES. Jan. 31, 1952 [Jan, 31, 1951], No. 2656/52. Classes 110(1) and 110(3) In axial-flow machines, particularly blowers and turbines, the.rotor blades, which cannot be radially displaced, are adjusted through a number of elements conected in series and common to all the blades, the transmission means from the last common element to each blade including screw threaded spindles. The pitch of impeller blades 2 is adjusted by means of a central gearwheel 8 which, is rotated. manually or by a motor, through a pinion 9. For each blade, there is a screw-threaded spindle 4 driven, through a gearwheel 7, from the gearwheel 8. The resultant longitudinal movement of a nut 5 is transmitted by linkage 6, 3 to the corresponding blade 2. The gearing may be replaced by chain drive. The pitch-adjustment mechanism of the individual impellers of a multi-stage blower may be coupled together, and the screw-threaded spindles of the individual impellers may be of different pitch. To permit the adjustment to be made while the impeller is running, the drive to the mechanism may include elements arranged coaxially with the impeller. Where a motor is used, it may rotate with the impeller, current being fed to it through sliprings.
