Abstract: 1,216,296. Electro-plating piled panel edges. O. A. BECKER. June 5, 1969 [June 20, 1968; Aug. 1, 1968; Oct.17, 1968], No.28527/69. Heading C7B. The cut edges of sheet metal panels bearing lacquer, synthetic resin or metal coatings are electro-plated for protection by placing them one on top of the other in a pile and bringing at least one side face of the pile into contact with an electroplating electrolyte, each panel being connected to a D.C. source. One embodiment, Fig.1 shows a side face of the pile 17 pressed against an absorbent wall 3 of a sealed container 1 containing the electrolyte and suspended anode sheets, the wall consisting of panels 5 of felt, sponge or foam, e.g. supported between wire nettings in a carrier frame 3a. Two such containers may be pressed on opposite side faces of the pile to electro-plate simultaneously. The pile may be held by plates 31, 32 and abutment rods 34, with Cu wire brushes 30 oscillated by electromagnets (not shown) for intensive contact. Vertical electro-plating strips 27, 28 of absorbent material may be provided to electro-plate edges of panels having punched cut-outs; these strips may contain anode rods (22), Fig.3 (not shown) surrounded by sieve-tubes (23). Electrolyte dripping of the panel 3 may be collected in a trough 10 and returned via a pipe 11 and float valve 12. The cut edges may be first Zn plated, then Cr plated; acid or cyanide electrolytes may be used. The cut edges may be cleansed before and after plating by reciprocating brush bars mounted on the upper holder plate 32 as a horizontal sprinkler. The cut edges of Al shut panels may be anodized by reversing the electrical connections for the above container. A second embodiment, Fig. 5 shows the pile 17 partly inserted through an aperture in a front wall 1a of the container 1 which is filled with electrolyte from a storage container 62 via a pipe 61 containing a valve 61a by compressed air introduced through a pipe 63, the aperture being sealed against the pile by movable wall portions 43, 44 guided by framing 53 and provided on their edges with inflatable hoses 47, 46 and sealing strips and operated by pressure cylinders 49 having piston rods 50, inflatable hoses 42 being inserted in U-section frame 41 for sealing the wall portions.

Title: Method and apparatus for packaging articles
IPC: B65B33/00
Filed: 1961-08-10
Abstract: 950,101. Packaging. M. E. WALLIS. Aug. 10, 1961, No. 28952/61. Heading B8C. [Also in Division B2] A method for packaging comestible articles by applying a surface coating of a highly viscous liquid which hardens at room temperature comprises passing the article horizontally through a series of thin sprayed films of the liquid. The method may be carried out by a machine consisting of a conveyer belt 10 which advances the article to pass through non-intersecting, continuous, thin, planar films f1-f6 and over a mechanism 32 which coats the bottom of the article. Each article A passes through the casing 42, heated by lamps 73, on the conveyer 10 which is divided by the mechanism 32. The liquid films issue from nozzles 44, 46, 48, 50, 52 and 54 which are positioned so that selected faces of the article are coated evenly as it passes through them. For example as the article. A advances to intersect the sheet f1 the liquid is cut off at 76 by the side d while the rest of the film 78 will be carried completely over the top of the article (see Fig. 4). As it moves away from the film, side c is coated. The mechanism 32 comprises a tank having holes in its upper surface through which the liquid is forced against the bottom of the article. After the article has been through the film f6, it passes over a bottom film thickness control mechanism 43, comprising a series of rotatable rollers 140 in a frame 120, and then on to a discharge conveyer 38. The nozzles may be rotated and moved closer together or further apart to coat different size articles (Fig. 8, not shown) and are fed by means of a system of piping from a reservoir (Fig. 7, not shown). Chilled or frozen meat may be given wax or plastics coatings. A coating of acetylated monoglycerides combined with ethyl cellulose may be used.

Title: System for eliminating gyro on-off drift effects
Inventor: QUINN JAMES A
IPC: G01C19/08
Filed: 1971-06-21
Abstract: 1331150 Gyroscopes SINGER CO 21 June 1971 [19 Nov 1970] 29015/71 Heading G1C [Also in Division H2] In an instrument gyro system of the type having a gyro wheel driven by a synchronous motor with a solid rotor and being characterised by a drift rate that remains uniform during a given synchronised period and that is different in random manner for succeeding on-off gyro operations, the error effect of the on-off gyro drift is eliminated by repetitively shifting the phase of the motor supply voltage so that resynchronisation of the supply voltage field and the rotor occurs at spaced points around its periphery corresponding to each phase shift, thus causing the drift error to have a sinusoidal characteristic whose positive and negative portions balance out during a normal gyro operation, Fig. 6 (not shown). The invention is applied to a conventional two axis gyro, Fig. 1 (not shown) whose wheel 12 is coupled to the driving motor M supplied at 108, 110 with periodically phaseshifted pulse trains which constitute a two-phase 90 degrees de-phased voltage at approximately 480 HZ. These pulse trains are produced by a circuit comprising an oscillator having a constant frequency output of 1.2288 MHZ which is fed to a conventional flip-flop stage 64 where it is progressively divided to produce a square wave pulse train of frequency 1À92 KHZ. This pulse train is passed to a processing and gating stage 66 wherein periodic pulse suppression occurs such that a 1À92 KHZ pulse train, pulse suppressed at repetitive time intervals, is fed to a phase shifting and frequency dividing stage 68 whose squarewave output may be filtered before being passed to the outputs 108, 110. Circuit elements 64, 66, 68 are described, Fig. 3 (not shown) and comprise an arrangement of series-connected flipflops (element 64), series-connected dual flipflops, a single-shot multi-vibrator with an RC circuit and a quad gating arrangement including a N AND gate (element 66) and a pair of flip-flops having inter-connected outputs and inputs (element 68). Typical waveforms produced by the various elements are described, Fig.4 (not shown).

Title: A method and apparatus for encapsulating liquids
IPC: B01J13/04
Filed: 1963-07-24
Abstract: A carbonless transfer paper comprises a paper or plastic backing coated with encapsulated liquid particles.  The liquid may be a solution of a coloured or colour-forming substance, e.g. a dye-containing aqueous or organic carrier, a liquid which undergoes a colour-forming reaction upon exposure to air or atmospheric moisture, or one component of an azo dye forming system (to be associated with similar encapsulated particles of the second component).  The capsules are rupturable by the pressure of a stylus or type-bar.  The capsules may be naturally adherent to the backing or a binder may be used which may contain one component of a colour-forming system.  The capsules are made by forming core particles which at least partly comprise frozen liquid, forming a dispersion of said core particles in a gaseous stream and spraying into said dispersion a solution of an encapsulating material in a solvent which is volatile below the freezing point of said liquid to coat said core particles with a continuous film of said encapsulating material.  The dispersion may be a fluidised bed of the particles.  The particles may be produced by coating a core of clay, silica, alumina, calcium carbonate, sodium carbonate, sodium hydroxide, sodium chloride, sodium thiocyanate, ferric chloride, ferric sulphate, crystal violet or metal powders with the liquid and then freezing.  The liquid may be coloured.  The encapsulating layer may be shellac, natural or synthetic wax, natural or synthetic gum, asphalt, tar, hard fat, gelatine, sugar, lacquer, varnish, cellulose nitrate, cellulose acetate, sodium silicate, gluten, starch, a methacrylate resin, polystyrene, a polyolefine, polyvinylchloride or the material sold under the Registered Trade Mark "Saran".
