Filed: 1968-01-03
Abstract: 1,164,591. Printed circuits. PHOTOCIRCUITS CORP. 3 Jan., 1968, No. 409/68. Heading H1R. [Also in Divisions C1, C3 and C7] Printed circuits are obtained from blanks plated by electroless deposition of metal on a substrate wherein the substrates have been rendered catalytic to such deposition by incorporating a filler comprising inert, solid finely divided particles coated with a cationic wetting agent and a Group IB or VIII metal, e.g. Pd, Au or Ag. The filler may be incorporated by mixing with the other components of the substrate, e.g.resin, prior to formation thereof, or by impregnating after formation or by coating with an ink or an adhesive including the filler, on one or both sides of the substrate. The catalytic filler may not be uniformly dispersed in or on the substrate; thus the external or internal surfaces or the sides of holes drilled through the substrate may or may not be catalytic. The substrates may be separately coated by vapour deposition or electroless deposition with a metal film or foil prior to electroless deposition according to the invention. A further electrolytic deposition may be carried out after the electroless deposition. The production of single and multi-layer printed circuit wiring boards is described including the use of resin masks and subsequent etching by spraying with or immersing in the etchant, e.g. FeCl 3 or NH 4  persulphate. A series of drawings are provided illustrating these techniques, a typical example comprising (a) initially metal coating, (b) covering with a resin mask, (c) drilling a hole through the substrate, (d) further coating those areas not covered by the mask and the sides of the hole, (e) dissolving the resin mask, and (f) etching away the initial layer of metal covered by the mask.

Title: Improvements in or relating to feeding mechanism for shaping or other paper working apparatus
IPC: B65H11/00
Filed: 1924-01-08
Abstract: 210,415. Bobst et Fils Soc. Anon., J. Jan. 26, 1923, [Convention date]. Stopping-arrangements.-A sheet-feeding apparatus for shaping or other paper-working machines is constructed with a sheet-feed table 1, Fig. 1, to which the sheets are normally fed from a pile 3, the table 1 being fitted with tapes which advance the sheets to the shaping machine B. When hand-feed is required, the table 1 and its associated parts can be pivoted about its supporting shaft 10 by means of gears 19, 24, 25 operated by a crank 26, the table 1 thus being moved to the inoperative position shown in Fig. 2, forming a space through which the operator can pass. A hand-feed table 2 can then be moved into the operative position shown in Fig. 2 so as to permit of hand-feed of the machine. The sheetseparating mechanism is driven from a shaft 10 on which is a freely mounted gear 39 driven from the same bevel gearing as a gear 40 for driving the tapes of the table 21. When the sheets are separated automatically the gear 39 is clutched to shaft 10 by the clutch shown in Fig. 8. This clutch comprises a spring-pressed sleeve 52 splined to the shaft 10 on which the wheel 39 rotates freely. The sleeve is moved axially to disengage the driving-connection between a slot 55 in the sleeve and a tooth 56 on wheel 39 by means of a lever 48 operated by a cam 46 on a shaft 45 operated by a crank 44. The lever 48 is provided with an inclined surface 49 which engages a roller 51 on the sleeve 52 and moves the sleeve to the position shown in Fig. 8 to declutch the drive. The shaft 10 is locked in a predetermined position by a roller 59 on a spring-controlled lever mounted on the lever 48. The roller 59 engages a recess in a flange 61 in a cap secured to the shaft 10 bv the key 54, and locks the shaft when the drive is declutched.

Abstract: 767,247. Lathe details. FISCHER AKT.- GES., G. Jan. 12, 1955 [Jan. 12, 1954], No. 967/55. Class 83 (3). A steady-rest for lathes &c. for turning long workpieces which warp and run eccentrically during the machining operation, comprises transmission - means between the machinespindle and steady-elements so that the latter oscillate in timed relation to the work and follow the eccentricity thereof. This eccentricity may be caused by relief of stresses during machining, such eccentricity being measured by gauge and the steady-elements set accordingly. A bracket 18, Fig. 3, longitudinally adjustable along a guide 17, on the lathe frame, supports a member 23 which carries the steady-rollers 40. The member 23 may be adjusted towards and from the work 6 by bolts 21 secured to the bracket 18 and engaging slots in the member 23. The steady-rollers 40, Fig. 1, are supported on squared oblique spindles 36 by hubs 37 adjustable along the spindles to vary the eccentricity of running from zero to a maximum at the right-hand end. The spindles 36 are driven by gears 28, 29, 32, from a shaft 13 carried in a separate bracket 11 on the lathe frame. A telescopic connection and universal joints connect the shaft 13 and the spindle 25 carrying the gear 28. The oblique spindles are driven at the same speed as the work by a chain-drive from a sprocket 7 on the spindle to a sprocket 10 on the shaft 13. The sprocket 10 is secured to a hub 14 by bolts 16, the holes for which are elongated to permit adjustment to bring the movement of the steady rollers into phase agreement with any eccentric running of the work 6. If a larger adjustment is required the pinion 28 may be released on its shaft to vary the phase relationship.
