Abstract: 1,250,805. Electroless plating of non- metallic substrates. HOOKER CHEMICAL CORP. Nov.11, 1968 No. 53301/68. Addition to 1,221,111. Heading C7F. A metal free non-metallic substrate is contacted with a low oxidation state phosphorus compound in a solvent and then contacted with a metal salt, the metal being selected from Groups IB, IIB, IVB, VB, VIB, VIIB, and VIII of the periodic table, and subsequently electroless and electrolytically plated with e.g. Ni. The substrate may be cloth, paper, wood, cork, cardboard, clay, porcelain, leather, glass, asbestos, cement or plastics. Many examples of plastics are described which may be filled with glass, carbon, talc, asbestos, wood, flour wax or nylon. The phosphorous compound may be trihydroxymethyl phosphine, phosphorus sesquisulphide, P 4 H 2 , phosphine, diphosphine, hypophosphorous and phosphorous acids and salts thereof or compounds made by reacting phosphorus with nucleophilic agents or organometal compounds. The solvent for the phosphorous compound may cause the surface to swell and a large number of solvents are described. The surface is then contacted with an inorganic or organic salt of Cu, Ag, Au, Cr, Mn, Co, Ni, Pd, Ti, Zr, V, Ta, Cd, W or Mo. A complexing agent may be used and the solution may be aqueous or non-aqueous.

Abstract: 1,250,831. Time sharing system. R.C.A. CORPORATION. 13 Jan., 1969 [7 Feb., 1968], No. 1916/69. Heading G4A. A subsystem in a time-shared task performing system keeps account of each user's employment of the component parts of the system and contains a register matrix having storage locations each containing a rental weight register and an elapsed time register for each unit, a counter sequentially accessing the contents of the registers, an adder generating the sum of the elapsed time and rental weight values and returning the sum to the elapsed time register and means allowing the system to access the rental weight register contents to update their value and return the updated value. The subsystem gates are operated under the control of a timer producing pulses t 1 -t 13 , t 1 -t 6  being used for the time updating and t 7 -t 13  for weight modifying. At t 1  the counter 30 contents are applied to a decoder 18 to access one of the memory locations which at t 2  is stored in registers 22, 24. At t 3  the contents of the registers are applied to the adder 40 and at t 4  the sum is stored in register 24. At t 5  the contents are returned to the memory and at t 6  the counter is incremented. At t 7  the system which may be a computer supplies an address of one of the memory locations and at t 8  the contents are stored in registers 22, 24. At t 9  the weight value is supplied to the system for updating where necessary, i.e. to account for the different weighting values of the component parts of the system. The updated value is returned at t 10  and at t 11  the time value is accessed to enable the system to compute the charges to be billed to the user, the value being returned at t 12  and the contents of register 22, 24 being stored at t 13 .

In a vehicle wheel 12 a flange 40 formed on a spider 16 is resistance seam welded to the rim 14 by a plurality of circumferential seam welds, each including a series of overlapping weld nuggets. A seam weld is accomplished simultaneously at 90 degree intervals around the circumference of the wheel 12. The spider 16 is first press fitted into the rim 14 and a mandrel 50 is inserted into the opening 44 of the spider and secured thereto by pins 51 provided on the mandrel which engage openings 42 in the spider. A weld nugget is produced at 90 degree intervals by electrode wheels 60, 62 which are forced into contact by piston and slidable yoke assemblies 53, 58. The electrodes 60, 62 are de-energized and the mandrel 50 turned so that a second weld nugget partially overlaps the first and this process is repeated until the desired length of seam weld is formed. A water source 63 cools the rim during welding operations. The electrode wheels 60, 62 are positioned in planes angled with respect to each other to achieve a point contact with the rim and flange. A single stage welding unit working on one area of the wheel 12 at a time may alternatively be employed.

The network may be produced by passing a corded web of unbonded crimped staple fibres between rows of cog teeth on cylinders. Successive rows of teeth are displaced by one-half pitch. As shown in Fig. 7, the unbonded web 34 is passed between cog teeth 78 on a cylinder 74 and co-operating cog teeth on satellite rolls 80. The satellite rolls are all driven by a common chain 90 and individual rolls may be brought into or out of co-operation with the cylinder 74. The web is carried between the cog teeth by an endless conveyer 100 consisting of narrow belts which run between the rows of cog teeth. After forming, a binder is incorporated in the network by spraying; in the use of thermoplastic fibres bonding is by heating. The fibres may be hogs' hair, cotton, sisal, hemp, nylon, rayon, acetate, polyester, acrylonitrile polymers, polypropylene, polyvinylidene chloride-polyvinyl chloride copolymers or glass.

Abstract: 1297851 IGFETs PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Feb 1970 [1 March 1969] 9376/70 Heading H1K An IGFET has its gate insulation protected by a parallel connected diode comprising at least one PN junction, each junction and the diode as a whole having a breakdown voltage of less than 15. The diode may be formed by diffusion in the transistor substrate. Fig. 8 shows a tetrode with two annular gates 8, 9, each protected by a pair of back to back diodes to permit biasing the gates in either polarity. One gate carries a fixed bias while the input signal is fed to the other. A substrate of 10 ohm cm. P- type silicon is used and each diode pair consists of a P+ zone within an N-type zone which is adjacent, and in another embodiment, surrounded by a further P + zone. The further P + zone 17 associated with the input gate extends to source diffusion 3 to which it is shorted by a surface metallization. Though the corresponding zone 32 is connected via the substrate it may have a lateral extension to drain zone 4. The pair of diodes 30-32 is shown located within the inner gate but the gates may be widely spaced locally to accommodate the diodes between them. Silicon oxide or nitride is used in the insulating layer and aluminium for electrodes. All the N layers are formed in a single phosphorus diffusion step and the P + zones by a boron diffusion. External gate connections are made to pads 14, 35 which directly overlie the diodes to provide them with a low resistance charging path. If gate voltages of only one polarity are to be used, one diode of each pair can be dispensed with, i.e. by eliminating zones 22, 34. Corresponding single-gate embodiments are described and an alternative interdigitated source-drain configuration suggested.

The solutions may be those resulting from the reduction of esterified and N-blocked precursors for the said cephalosporanic acids with zinc and formic or acetic acid, after removal of unreacted zinc. The solution, preferably after concentration, is mixed with methanol and a suitable acid, e.g. hydrochloric, perchloric, or p-toluene-sulphonic acid or Amberlyst 15 (Registered Trade Mark), and the resulting methyl formate or acetate is then distilled off, preferably under reduced pressure at about room temperature. Phosphorus oxychloride may be used in place of the said acids, since it reacts with the methanol and also with water produced by the esterification reaction, to provide hydrochloric acid. The substantially aqueous solutions remaining after the distillation may be further purified by the process described in Specification 1,317,159.
