Abstract: 1,229,723. Electro-chemical analysis. INTERNATIONAL BUSINESS MACHINES CORP. July 1, 1969 [July 15, 1968], No.33043/69. Heading G1N. The concentration of a component of a fluid 1 is measured using two identical glass electrodes 5, 6, the ion sensitive surface of one being contacted by an electrolyte 13 containing a reagent that reacts with said component and of the other being contacted by a similar electrolyte 14 not containing the reagent. Semipermeable membranes 3, 4 separate the electrolytes 13, 14 from the fluid 1 but allow the component to diffuse through. The electrodes may be pH sensitive and have HC1 electrolytes 7, 8 and Ag- AgCl leads 9, 10. Electrolytes 13, 14 may be KH 2 PO 4  solutions. For determining glucose in blood, the reagent is the enzyme glucose oxidase, producing gluconic acid and hydrogen peroxide. For determining urea in blood, the reagent is urease, producing ammonium carbonate. In an alternative arrangement Fig. 2 (not shown) the electrodes comprise ion sensitive glass tubes (20, 22) through which the fluid flows, membranes (23, 24) holding the electrolytes (32, -33) against the inner surfaces of the respective tubes.

Abstract: 1,229,861. Ornamenting. BEST STAMP & MFG. CO. 22 Jan., 1968 [13 Feb., 1967], No. 3283/68. Heading B6G. [Also in Divisions B3 and H1] Indicia are produced on an object having a surface of an abradable material by coating the portion of the surface with a protective composition resistant to abrasion and comprising a polyamide or a major proportion of polyvinyl alcohol or of polyvinyl alcohol and polyvinyl acetate and being susceptible to a solvent, rendering selected areas of the coating incapable of being acted upon by the solvent, dissolving the remainder of the coating in the solvent to present coated and uncoated portions of the surface, and abrading the surface sufficiently to remove the material from the uncoated portions. The coating composition may be light sensitive and the desired coated portions formed by exposing the coating to light so as to insolubilize the coating at these points. The object may be a multi-layer plastics or metal clad laminate where it is desired to selectively abrade certain surface areas to erode the top layer of the laminate and reveal a lower layer, e.g. two colour melamine or phenolic laminates may be selectively abraded to produce a multi-colour sign, or a copper clad insulation layer may be selectively abraided to produce a printed circuit. Glass, plastics or metal articles may be selectively abraded to produce an engraved appearance or a cut-glass effect. Small plastics, glass or metal parts may be cut from a sheet of base stock. The object may be cleaned to render it susceptible to receiving a resin coating, e.g. by degreasing and dipping in chromic cleaning solution and primed by application of a coating of polyvinyl acetate aqueous emulsion by flush coating, brushing, spraying or centrifugal spin coating. The polyvinyl alcohol-polyvinyl acetate film may be plasticized with, e.g., glycerine and may be made light sensitive by inclusion of a light-sensitizable catalyst, e.g. potassium dichromate. The coating may be applied by flush and dip coating centrifugal coating. The selectively coated object may be abraded by blasting with alumina powder, silicone carbide. After the abrading the protective coating may be removed.

Abstract: 1,250,174. Mechanical switches. AMP Inc. 2 Sept., 1969 [27 Sept., 1968; 26 June, 1969], Nos. 45877/68 and 32208/69. Heading H1N. A switching device suitable for transmitting numerical data comprises a plurality of sliders 12 to 17 each of which operates one of a respective set of contact pairs according to its longitudinal position. Each slider is associated with a set of ten spring fingers 30 (Fig. 2) which may be formed integrally, as shown, from a flat lamina 27 of spring copper or may be subdivided into a number of sections, each with a terminal tag 28. The six sets of contact fingers are mounted in a housing 25 with transversely extending rods 31 forming fixed contacts common to corresponding fingers 30. Each slider has a notch 32 which, when positioned adjacent a finger 30, allows that finger to engage its associated rod 31. Each slider has grooves 11 aligned with digits 0 to 9 on the front panel 1 and extends behind an indicator slot 8, 9 or 10 such that, when moved by engaging a suitable implement (e.g., a ball-point pen) in a selected groove 11 and moving it downwards to the end of the appropriate slot 2 to 7, the contact finger then operated is indicated by the corresponding digit appearing in the slot 8, 9 or 10. After read-out of the contacts thus set up by moving the individual sliders, all six sliders may be simultaneously returned to their non-operated positions by means of a lever 35. In a modification (Fig. 4, not shown) the housing 25 is pivoted (at 20) so that it can be moved away from the sliders between readings, allowing all the fingers 30 to engage rods 31 in the rest position, thereby keeping the contact areas clean and avoiding unnecessary flexing of the fingers as the sliders are moved. A solenoid (21) is energized to cam the housing into position for a read-out.

Abstract: 1,250,764. Control of A.C. motors. BBA GROUP Ltd. 10 March, 1969 [19 March, 1968], No. 13192/68. Heading H2J. An induction motor M is stopped by actuating a micro-switch to de-energize relay IL and disconnect the motor from the supply. Relay IIL is connected across capacitor Q and rectifier V which are now supplied by the motor moving under its own inertia. Capacitors S, T, V, are thus connected across the stator windings so that the motor is self-excited for braking. As the motor speed decreases, the relay RL becomes insufficiently energized to hold contact Ra, whereby relay IIIL is energized from capacitor Y. This causes the stator windings to be shortcircuited, and the motor is brought to rest. Capacitors X and Z maintain the relays IIL and IIIL energized for a period longer than the stopping-time of the motor. In a modification, two stages of capacitive braking are introduced, and this is followed by D.C. injection braking, Figs. 2 (not shown). In a further embodiment the contactors are replaced by thyristors, Fig. 3 (not shown).
