Filed: 1951-12-20
Abstract: 730,790. Washing. SULZMANN, E. Dec. 20, 1951, No. 29815/51. Class 138 (2). A washing process using a plurality of washing machines I ... VI interconnected in the manner of a ring, consists in isolating a first group (b) of the machines from a circulation of liquid which is maintained successively through a second group (a) of the machines, whilst removing washed articles from a further machine (VI in Fig. 4) disconnected from the ring and refilling it with articles to be washed, so as to enable washing to be effected within the first group (b) by the introduction of chemicals and heat into the machines thereof substantially without transfer of contained liquid from one machine to the other within that group, rinsing being effected in the second group (a), and also to enable a fresh machine containing washed and rinsed articles to become available in each washing stage for disconnection from the ring and for emptying and refilling as aforesaid, by reforming the two groups at the end of each stage one machine in advance of their previous arrangement in the direction of the circulation of liquid. Liquid may be circulated through both groups (a) and (b) (Fig. 4), prior to isolation of the first group (b) (Fig. 5). A third group (c) (Fig. 5) of one or more machines may be isolated from the circulation for one stage or for half a stage to enable articles to be soaked in stationary liquid contained therein. In Figs. 1 to 3 (not shown), twelve machines are connected in a ring and each stage lasts five minutes. In Figs. 4 to 6 six machines are used, each stage lasting ten minutes. A waste outflow 11 and a through-flow 12 are provided between each pair of machines, these connections being controlled by plugs 13 or valves. In the first half of one stage (Fig. 4), machine VI is out of operation and is being charged with linen to be washed. In the second half of this stage (Fig. 5) the through-flow 12 between machines V and VI is opened so as to admit liquid to machine VI up to the level determined by a central overflow 15, in order to soak the linen. Steam may be added at 18 in machine IV, and alkali and soap in machines III and/or IV. Acidification may take place in machine I 2¢ minutes before the end of the rinsing process. At the end of the ten-minute stage machine I is withdrawn from operation and the fresh water feed 17 transferred to machine II, so that machines II, III act as rinsing machines, and machines IV, V and VI as washing machines (Fig. 6, not shown). Specification 672,755 is referred to.

Title: Improvements in the driving and feeding arrangements for the tool heads of drilling,milling, boring, reaming and like machine -tools
IPC: B23B47/20
Filed: 1947-11-12
Abstract: 647,402. Drilling machines ; actuating slides. REGIE NATIONALE DES USINES RENAULT. Nov. 12, 1947, No. 30155. Convention date, Dec. 30, 1946. [Class 83 (iii)] A tool-head A for a drilling, boring, milling, reaming or screw-tapping operations is mounted on a slide B and adapted to be fed and returned slowly by a reversing electric motor C which also rotates the tool or tools through gearing, a second reversing electric motor K being provided for rapid traverse of the head in either direction. The motor C drives the tools through pinions E<SP>1</SP>, E and a shaft D while feeding the tool-head A through bevel gears E<SP>2</SP>, E3, pinions F, F<SP>1</SP>, and a worm G which drives a worm wheel H attached to a sleeve V connected to the head. A nut I formed on the end of the sleeve V is in threadedengagement with a screw J which is connected to the slide B. The screw J is provided at one end with a worm wheel M and worm L forming an irreversible coupling adapted to hold the screw stationary while the nut I is being fed thereon. For rapid traverse, the motor K drives the worm L and screw J to increase the rate of travel of the nut I. A cam P on the head A actuates a lever Q against a spring-pressed plunger Q<SP>1</SP> which operates contacts in a distributer N on the slide B so that the motors are controlled by relays. A spring-urged dog clutch (not shown) on the worm G is adapted to slip so as to prevent the strain on the screw J from becoming excessive. The pinions E<SP>2</SP>, E<SP>3</SP> may be reversed in order to reverse the drive, or interchanged to provide a different drive ratio. In a modification, Fig. 3, the irreversible coupling is replaced by an electro-magnetic clutch which, when de-energized, retains the screw J in a stationary position by gripping a flange 0 formed on a driving shaft J<SP>1</SP> for the screw J between a fixed face U and a disc T pressed by a spring R. When the motor K is energized, an electromagnet S attracts the disc T against the influence of the spring R and releases the grip on the flange 0 so that the shaft J1 may be driven by spur gearing from the motor. In a further modification (not shown), the irreversible coupling is replaced by a cone clutch on the armature of the motor K which in this case is of the sliding-armature type. On energizing the motor, the armature is drawn into the field of excitation against spring- pressure so as to disengage the clutch.

Title: Improvements in or relating to metal plating
Inventor: DUNSTER DAVE FRANCIS THOMAS
IPC: H01L21/00
Filed: 1963-08-01
Abstract: An insulator or semi-conductor (e.g. of Si) is initially metallized in any way and then plated from an electroless plating solution with a layer of a first metal or alloy (e.g. Ni or Cu) by successive applications interspersed with "flashes" of a second metal (e.g. Au) from another electroless plating solution, the flashes serving to prevent grain growth of the first metal and thereby to provide an adherent non-spongy coating.  As illustrated in the Fig. (not shown) a semi-conductor Si slice, having impurities diffused therein to form junctions which appear under a layer of SiO2, is cleared selectively by weak HF to remove the SiO2 in areas to be coated with Ni.  An initial layer of Ni is coated either from an electroless bath based on phosphate or by evaporation and then sintered in air or N2. This Ni is roughened by etching and Ni layers and Au "flashes" are then built up in succession by electroless deposition using a phosphate bath for the Ni and a cyanide bath for the Au which works on the replacement process Au for Ni.  The composite plated layer may be subsequently sintered.
