IPC: G05B19/18
Abstract: 1,054,378. Machine tool details. FOSDICK MACHINE TOOL CO. Aug. 23, 1963, No. 33518/63. Headings B3B and B3C. [Also in Division G3] A machine tool comprises means for advancing a spindle 5, Fig. 13 (not shown), rapidly to the surface of a workpiece and then for feeding it to a predetermined depth. The spindle 5 is supported in a head 3 which can be adjusted vertically by coarse and fine adjustment hand wheels 9, 10. The machine may be numerically controlled or set up manually by switches on a panel 45, and include tool selection, by switches 47, 48, 52 or automatically, the tool in use being indicated on a board 46. The work-slides may be positioned by gauging apparatus as described in Specification 893,795. A control rod 18 moves with the spindle and co-operates with two sets of gauges-one for coarse and one for fine feed. The position of the rod 18 can be adjusted by push-buttons 54, 55 or automatically by a motor 24, Fig. 5 (not shown), and gearing including a nut engaging the rod, to compensate for different tool lengths. The adjustment for tool length is set up manually by potentiometers on a board 56, so that, in operation, adjustment is effected by a comparison circuit. In its downward movement, a switch 28 on the rod 18 engages one of indexible abutments 31 on the coarse gauging means to start the slow feed and the rod then engages and carries down a similar abutment 35 on the fine gauging means until a switch 36 is operated through a lever 81. The spindle is retracted after a dial indicator 37 has been actuated to indicate the completion and accuracy of the machining stroke. The gauges are set by push-buttons or automatically by a motor 43 and the settings are indicated by dials 27, 33 visible in a window 40, Fig. 13 (not shown). A rod in each of the gauging drums is selected by energizing a particular contact of a selector switch associated with the drum, so that when the drum rotates, a brush completes a circuit to a solenoid 61, Fig. 6 (not shown), to actuate a pawl and stop the drum, the engagement of the pawl causing the drive to that drum to slip. Thus, for instance, the position of an abutment 31 is determined by moving its carrier 30 downwardly until the selected gauge bars are caught between stops 66, 67. The fine feed gauge bars 69-72 are caught between stops 78, 80, the latter being mounted on the lever 81. After a gauging operation is complete, the gauge bars are moved axially to their initial positions by springs. Before the next gauge bars are selected, the gauge carrier 30 is raised by the motor 43 through crank mechanism until an upper plate 93 actuates a switch to start the indexing movement. The spindle-quill is rack-fed by a motor driving through an electrically-controlled clutch which can be disengaged to allow the rapid traverse from a separate motor. A further such clutch stops the drive at the end of the feed movement. Should the feed overshoot, the lever 81 engages a safety switch to stop the feed.

Abstract: 1,225,300. Drawing and supporting glass sheet. LIBBEY - OWENS - FORD CO. 7 Aug., 1968 [30 Aug., 1967], No. 37764/68. Heading C1M: To create a film of air between a glass ribbon 17 and a supporting surface 28 over which it is moving while in a highly heated softened condition, particularly when a glass sheet is drawn vertically and deflected over a bending roll 28 to a horizontal direction or for the take-off roll at the end of a float glass bath, a supply of the air is maintained under pressure behind the supporting surface and directed through a slot 29 extending generally transversely to the path of the ribbon 17, the air flowing in individual streams, as through apertures 42, Fig. 3, or a mesh 51 of stainless steel, Fig. 5, into a chamber 43 or chambers 59, behind the surface so as to be dispersed within the chamber(s) to give uniform flow against the ribbon 17. As in Fig. 3, the apertures 42 are in side walls 41 of a member 39 so that the air streams mix in chamber 43, the member 39 having fixing flanges sliding in a pair of upper slots 37. In a modification, the apertures (49) are in the base (48) of a similar member (44) with thick side walls (46) which are undercut at (47) so that air through the apertures impinges against the side wall undercut. As in Fig. 5, the chambers 59 are formed between a member 52 and the walls of slot 29, the mesh 51 resting on the bottom of a pair of lower slots 38 and flanges 56 on member 52 extending into slots 37 to give two chambers 59 and two chambers 60 above. The member 52 is secured by bolts 55 into cross pieces 36 in the lower part 35 of slot 29.

When the composition is used in an imaging process, it is placed on a transparent injecting electrode comprising glass coated with Au, SnO, Cu or Cu 2 I 2 , or a cellulose acetate sheet. A blocking electrode in the form of a roll or sheet of conductive rubber, steel, Al, Cu, brass, baryta paper, polyvinyl fluoride, polyurethane, cellulose acetate, polystyrene, PTFE, or polyethylene terephthalate is provided. The pigment image may be fixed by coating it with a thermoplastic layer or transferred to a paper sheet by an electrostatic field or an adhesive tape and there fixed by spraying with a binder or laminating an overlay on it.

For stripping, the members 9, 11 are unscrewed to a desired length and the cable introduced into the stripper through bores 16 and 15 against the blade. As member 9 is rotated around 11, the blade follows a helical path to cut the sheath and then along a circular path to trim the cut face. The head 6 or the pitch of the screw thread can be altered to suit cable diameter and the operation can be done either manually or automatically.

A process for making a lithographic plate comprises imagewise exposing a material comprising a support coated in either order with a metal layer and a layer which reacts on exposure with the metal layer at the boundary of the layers to form an interreaction product which differs in hydrophilicity from the metallic and reactive layers, so that the product is formed at the exposed areas and all of the top layer is consumed on these areas, treating the top layer with water which wets the hydrophilic areas and then with an oily ink to ink the oleophilic areas. If the reactive layer is the top layer, the reaction product and the removing reactive layer may be removed by washing before wetting and inking; the support in this case differing in hydrophilicity from the metallic layer and preferably being a hydrophilic grained aluminium support. The reactive layer may be arsenic tri- or perta-sulphide and the metallic layer may be copper, silver or an alloy thereof. If the metallic layer is the top layer, generally the remaining metal areas after exposure are oleophilic and the reaction product hydrophilic but if the metal is cleaned and treated with gum arabic before exposure, the metal areas after exposure are hydrophilic.

Abstract: 1,234,343. Cathode-ray tubes. SONY CORP. 11 Nov., 1969 [13 Nov., 1968], No. 55231/69. Heading H1D. In a co-planar triple-beam tube for colour television wherein the three beams are converged by an auxiliary lens at the centre of a main lens from which the beams diverge, the beams being subsequently converged by deflection means, the focusing effect of the auxiliary lens is different for the centre beam than for the two outer beams; this is corrected by further focusing means adapted to influence either the centre beam only or the two outer beams only. Fig. 4A shows a cross-section of a convergence deflection system wherein the outer beams are converged by the electric fields between the inner plates P2 at anode potential VP2 and the outer plates P1 at a lower potential VP1. In Fig. 4A a cylinder 15 at potential VP1 is provided within the inner plates P2 to form a converging lens providing additional focusing for the centre beam. Outer cylinders of smaller diameter may be placed adjacent each end of the cylinder 15 and connected to the potential VP2 (Fig. 7, not shown). The voltage VP1 may be of parabolic waveform (Fig. 6, not shown) to provide dynamic convergence, and in this case the system will provide dynamic focusing also. In an alternative arrangement, Fig. 5 (not shown) cylindrical electrodes are arranged between P1 and P2 and between P1<SP>1</SP> and P2<SP>1</SP>, and are connected to a higher potential than VP2 to provide divergent lenses in the paths of each of the two outer beams.
