Title: Improvements in and relating to the coating of articles with metals
Inventor: KERRIDGE FRANK ENOCH
IPC: H01B1/00
Filed: 1963-03-27
Abstract: A preheated surface of an article, e.g. a capacitor dielectric disc of barium titanate or mica, is coated with metal, e.g. Ag, Au or one of the Pt group, e.g. palladium, by the momentary application of a rod of thermoplastic metallizing composition containing the metal in powder or flake form, to cause part of the rod to melt and to be deposited on a portion of the article.  The deposit retaining the same cross-section as the rod, is then cooled and solidified, after which the article is fired in the usual way to remove organic matter. As described, the composition, comprising 80 parts Ag flake, 3 parts low melting point borosilicate glass and 15 parts paraffin wax and zinc resinate mixture, is extruded through a die to form a rod of desired section, which when cooled is suspended above a conveyer belt carrying the dics heated to 60-80  DEG C. and is applied to each disc as it is brought beneath the rod for a period dependent on the thickness of deposit required.  Both sides of the discs may be coated simultaneously by arranging two rods moving on a common axis.ALSO:A preheated surface of an article, e.g. a capacitor dielectric disc of barium titanate or mica, is coated with metal, e.g. Ag, Au or one of the Pt group, e.g. palladium, by the momentary application of a rod of thermoplastic metallizing composition containing the metal in powder or flake form, to cause part of the rod to melt and to be deposited on a portion of the article, the deposit, retaining the same cross-section as the rod, is then cooled and solidified, after which the article is fired in the usual way to remove organic matter.

Filed: 1947-05-08
Abstract: 654,361. Moulding glass. RUBISSOW, G. A. May 8, 1947, No. 12502. [Class 56] [Also in Groups V and XXII] In a centrifugal casting machine the passage leading from the pouring gate to the mould has an overflow opening from which metal may be discharged when the mould has been filled. Two or more moulds M arranged in a rotary casing 11. Fig. 1, each comprise mould cavities S and a gate G which communicates through a member R<SP>1</SP> and a passage 20 with the bottom of a downwardly flared pouring chamber 19 which rotates with the casing. The pouring chamber is adjustable in guides 27 by hydraulic or other means to align the passages 20 with the openings into the gates G. In each member R<SP>1</SP> is an outlet 53. As a result of rotation of the apparatus in the direction of the arrow A, metal flowing from the passage 20 normally passes into the gate G, but when the mould is filled. overflow can occur from the passage 53 and may be detected visually through a window 62, or a photo-electric cell may detect the sound and/or glare of the overflow. In a modification, two mould casings 11A, Fig. 10, are mounted either by a bayonet joint as at 124 or by screw-threaded engagement as at 124A to discs formed with bevel gears 123 meshing with a non-rotating gear 125. As the shaft RS is driven the moulds M are thus rotated about two axes, X-X and Y-Y. The molten metal is fed to the moulds along axial gates and any overflow escapes through passages 53A. The mould casings may be heated electrically by current supplied through sliding circular contacts 130, 131. In addition to the casting of metals the machine may be used for plastics or glass.

Abstract: 1312602 Monitoring material opacity photoelectrically SINGER CO 4 May 1971 [18 May 1970] 12876/71 Heading G1A [Also in Division G3] Material being sewn is automatically steered so that the stitches are placed at a constant distance from its edge 16 by an arrangement which uses a photo-detector 19 to detect the edge position one average stitch length ahead of the needle and further photo-detectors 20---22 placed ahead of the needle to detect the amount of curvature of the approaching edge so as to regulate the feed rate, slowing it for high curvature, to ensure that the steering mechanism has time to operate. A second photo-detector 23 adjacent the needle provides a signal which compensates for variations in the opacity of the material. The photo-detectors are photo-diodes having the bar shape shown so that their resistance is proportional to the length of bar exposed. The steering error signal is derived in a circuit Fig.2b, (not shown) comprising operational amplifiers in which the gain of the circuit is effectively modified by the signal from the opacity detector 23. This modulates the intensity of a lamp illuminating a photo-resistor (50) in the input circuit of the final operational amplifier. The same lamp illuminates further photo-resistors connected in a similar way in circuits associated with the feed-rate controlling detectors 20---22. The reference value for edge distance is nominally the centre line 17 of the detectors, but this can be offset by a variable bias voltage. The error signal is transistor amplified and applied to an "integrated transistor chopper" (82) Fig.3, (not shown) controlling a steering servo motor (M), with a lamp and photo-diode arrangement associated with a shutter in the machine to ensure that adjustments are made only between feed movements. The steering mechanism is not disclosed. A tachogenerator provides rate feedback for the servo drive. Zener diodes act as voltage limiters. Feed rate control. The outputs of the detectors 20---22, corrected for opacity in the manner of the distance error detector 19, are made unidirectional, "weighted" according to their distance from the needle, and combined according to a given formula to produce a single voltage for controlling the feed drive. Two alternative circuits are described (Figs.3 and 4) one of which produces a continuously variable drive signal and the other a variable mark/space ratio signal which controls a driving clutch.
