Title: Spark erosion machine
IPC: B23H7/28
Filed: 1978-04-27
Abstract: The electrical discharge machine tool has a work table and a quill head (20, 5, 10) arranged above the work table and having a rotatable quill (1) mounted therein, the bottom end (2) of which is connected to an interchangeable electrode holder. A drive without projecting components for a movement of the electrode holder in a plane at right angles to the feed direction is to be created at the quill head, in which drive this movement results by superimposing two linear movements. To this end, the bearing arrangement (5) of the quill is guided in two coordinate guides (13, 16; 17, 19) running at right angles to one another, each of which is provided with a separate linear drive (21). Here, the quill together with the electrode holder performs these translatory movements. However, the quill remains rotatable independently thereof. <IMAGE>

Abstract: 851,281. Welding by fusion. QUASI-ARC Ltd. May 20, 1959 [May 23, 1958], No. 16739/58. Class 83 (4). A longitudinal seam in a tube is internally welded by an arc torch on a support extending through the seam and using a flux-carrying electrode fed through the seam. The electrode is flux-cored or coated, and may consist of a core surrounded by wire windings in which flux is embedded such as is described in Specification 584,299. Conduits 11 for cooling water and shielding gas, e.g. argon or carbon dioxide, pass through the open seam and the support 7 for the torch 4 maintains the tube 1 in correct alignment. The seam is closed adjacent the welding- point by rolls 9 and the internal weld is made using a backing-plate 17. The tube 1 is fed by rolls 3 past the torch 4, is turned through 180 degrees by rolls 18 and is fed by rolls 19 past a torch 21 similar to the torch 4 for the seam to be externally welded. In a modification the external weld is effected by a torch positioned below the tube and adjacent the inner torch.

Metal or other sheets are fed to the gripper cylinder 6 of a printing &c. machine by a pusher-finger 17 secured to a travelling endless chain 16 which has an effective length approximately equal to that of the circumference of the cylinder, the chain making one cycle for every rotation of the cylinder. The front sprocketwheel of the chain 16 is driven through a pawl and ratchet device 19 by a chain 15 which engages a sprocket 14 driven indirectly from a drive shaft 5. The drive comprises a camplate 1, adjustably secured to the machine frame by studs 3, having a grooved cam track 7 therein in which a roller 8 engages. The roller 8 is mounted on a bracket 9, pivoted on the outer end of a lever 10 which is keyed to the shaft 5, having gear teeth 11 engaging a toothed arc 12 on a lever 13. The lever 13 is loosely mounted on the shaft 5, and is secured at its outer end 13a to the sprocket 14. The driving arrangement is such that the pusher 17 will be retarded temporarily before passing over the front sprocket; to allow the tail of the sheet to be drawn by the cylinder grippers clear of the pusher, and then the pusher will be accelerated temporarily to preserve the timing of the movement of the pusher. Several chains 16, each with a pusher 17, may be arranged side by side, each pusher engaging the sheet to be fed.

Abstract: 446,377. Boiler &c. furnaces. DUPUY, H., 27, Rue du Banquier, Paris. June 15, 1935, No. 17317. [Class 51 (i)] A solid-fuel furnace comprises an inclined surface A which is imperforate or provided with spaced air inlets only and on which is spread a layer of fuel supported at the bottom by an end plate B and means whereby the zone of active combustion is progressively moved away from said plate relatively so that ash and clinker resulting from the combustion can collect on said surface in the space between the plate and the combustion zone for comparatively long periods without interfering with the combustion. In Fig. 1 the surface A has spaced air inlets O1 .. 05, Air is first supplied through the lower inlet O1 and as the fuel thereover is burnt, that inlet is closed 'and the next higher inlet 02 opened and so on. The inlets may be operated automatically by valves controlled by means of heat or light sensitive devices located opposite the inlets. In another form, Fig. 2, the air for combustion enters from a chamber V. As the fuel near the air inlet is burnt the supporting plate B is moved further down the surface A. The downward movement of the plate may be controlled by a rack secured to the plate and engaging a pinion whose rotation is permitted at intervals by an escapement mechanism under the control of a heat or light sensitive device adjacent the combustion zone.

IPC: H04L12/18
Filed: 1929-06-06
Abstract: 313,130. Potay, M. June 7, 1928, [Convention date]. Selective signalling apparatus. -Relates to apparatus for repeating at a distance manually transmitted orders or the indications of apparatus such as a totalizer. As shown, orders transmitted by a manually operated handle 12 are signalled by an indicating drum 29. The handle 12 controls a contact arm 15 which co-operates with a series of contacts 1, 2, 3, &c. corresponding to the orders on the dial 13 and connected to corresponding contacts in the series 1<1>, 2<1>, 3<1>, &c. on a stationary plate at the receiver. A group of contacts the number of which is one less than the number of contacts 1', 2', 3<1>, &c. is mounted on a rotatable carrier 35 and is adapted to cooperate with all except one of the contacts 1<1>, 2<1>, 3<1> in each indicating position. The carrier is mounted on a shaft 33 carrying an escapement wheel 34 and adapted to be driven through friction gearing by a continuously driven shaft 30. The indicating drum also is geared to the shaft 33 and the arrangement is such that when the contact arm 15 is set into a signalling position the circuit of an escapement magnet 36 is completed over the appropriate contact at the receiver to permit the shaft 33 to rotate through a distance corresponding to one tooth of the escapement wheel 34 and thereby bring the succeeding order on the indicating drum into view and move the contact carrier 35 one step to again complete the circuit of the magnet 36 over the line selected by the transmitter. This cycle of operations is repeated until the selected line is open-circuited at the marked contact of the receiver by the carrier 35. In this manner a number of impulses is transmitted over the selected line to operate the indicating drum into a position corresponding to the setting of the transmitter. Distributors G, H are provided to facilitate the operation of a plurality of receivers by a corresponding number of transmitters in order to obtain a composed signal. The transmitters and receivers are connected to the outer contacts of the distributors G, H respectively and the arrangement is such that the contact arms 25, 26 mounted on a common shaft bring into operation corresponding transmitters and receivers successively. The Specification as open to inspection under Sect. 91 (3) (a) also states that the indicating drum may be driven directly from the ratchet and pawl mechanism. This subject-matter does not appear in the Specification as accepted.
