Abstract: 1,234,483. Anodizing aluminium; electrophoresis. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Nov. 11, 1968, No. 53424/68. Heading C7B. [Also in Division H1] An insulation coated conductor of Al metal or alloy wire or strip 1 e.g. for solenoid formation is produced by applying an insulating material 2 on the Al metal or alloy surface at uniform intervals and then anodizing to form an oxide coating 3 of locally reduced thickness, the density of the reduced thickness portions being 20-100 per 1 mm length of the wire or strip and the thickness reduction percentage of the coating at each of these portions being 5-50%. The insulating material may be natural or synthetic resin or glass powder applied by spraying over the surface of a previously heated Al conductor, whereby the powder is electrostatically attached to the conductor surface andthen fused with heat; by a fluidized bed coated process; or by electro-phoresis, where the powder is dispersed in a liquid and then fused with heat. An example specifies a silica powder-containing thixotropic epoxy resin applied on Al foil by photogravure printing to form square patterns arranged at 8Á intervals. Anodic oxidation may be effected in aqueous sulphuric, oxalic or chromic acid.

Abstract: 1,238,559. Radio receiving circuits. AUTOVOX S.p.A. 13 Aug., 1969 [13 Aug., 1968], 40427/69. Heading H3Q. A remote control device for a radio receiver such as is disclosed in Specification 1,160,684, using electronic tuning means, and particularly automatic tuning and scanning means, comprises a combined on-off switch 51, Fig. 3, and volume control 52, a tone control 53 and a band selection control C, Fig. 4, which switches in frequency modulation tuner FM or amplitudemodulation tuner AM, two bands being covered in the latter by rendering conductive or non- conductive diodes, e.g. D2 shunting inductors L2: tuning is by means of varactor diodes, e.g. D 1. The arrangement also includes controls for manual tuning and for switching over from manual to automatic tuning, comprising a potentiometer 61, Fig. 5, and three-position switch 60, which in a first position provides manual tuning, the automatic tuning unit RA being connected to earth while the sliding contact of manual tuning potentiometer 67 is connected over emitter-follower transistor T1 to electronic tuning means comprising varactor diodes D3. In a second " auto " position of switch 60, automatic tuning occurs, the base of transistor T1 being connected by lead 64 to the automatic tuning unit RA, while a third position of switch 60 provides for scanning to commence. Unit D provides for switching between " distant " and "local" " station reception: for " local " reception on A.M. bands a low value resistance 108 is shunted across receiver filter circuit 112 during scanning, by means of diode 106 which is rendered conductive from the bistable circuit BS, becoming non-conductive when scanning ceases. On the F.M. band, the bi-stable circuit BS switches the collectoremitter path of transistor 136 in shunt with tuned circuit 142. In addition, on both bands the amplification of an R.F. amplifier transistor 170 is reduced by the application of a potential from bi-stable circuit BS to the base of transistor 160, rendering it non-conductive: the collectoremitter path of this transistor shunts the emitter-circuit resistor 172 of transistor 170.

Abstract: 1,252,338. Cathode-ray tube circuits. A.S. NYCOTRON. 15 July, 1969, No. 35610/69. Heading H4T. In an arrangement for displaying curves on the screen of a cathode-ray tube by the application of beam bright-up pulses (indicative of curve plotting points) during the formation of a line-scanned raster the duration of each brightup pulse, within predetermined upper and lower limits, is made dependent on the slope of the curve at the position indicated by such brightup pulse. This manner of operation allows curves to be traced with a luminous density which is independent of the slope of such curves, i.e. compensation is effected for the decreasing density of plotted points with increasing slope of the curve. Figs. 1 and 2 show the result of plotting the curves shown at a, by the arrangement of the invention, curves c, in comparison with the conventional manner utilizing brightup pulses of constant duration, curves b. The raster is scanned with a fast vertical line scan and a slow horizontal (time-base) scan and the lower limit of the pulse duration is set at a value which gives satisfactory luminous intensity and continuity for a curve portion parallel to the horizontal scan. The maximum pulse duration is made adjustable, depending on the type of curve to be displayed so that " overshoot " when the curve direction is nearly vertical is prevented. This is shown at Fig. 3b in comparison with the original pulse curve, Fig. 3a. The arrangement is stated to be of advantage in medical electronics, e.g. in the recording of cardiograms.

Expanded polybutylene articles are produced by heating and compressing expanded particles of polybutylene or butylene copolymers until fused in a confined space, e.g. a closed mould, from which gaseous or liquid substances can escape but not the expanded particles. Heating medium can be passed through the confined space e.g. through at least one probe or perforated tube, which is withdrawn before fusing and compression of the particles. The particles, which are preferably closed-cell, may be compressed from two directions toward the centre of the mould e.g. by 5-60% of their original bulk volume. The heating medium is preferably recycled. Hot steam may be used as the heating medium but heating may also be effected with infra-red radiation or by blowing in hot air. The particles may be coated with a small amount of a substance having a high dielectric loss, e.g. water, aqueous salt solutions and heated in a high frequency field. Copolymers of butylene, e.g. with isobutylene, ethylene, may also be used.

Abstract: 1,257,558. Glycols, purification by distillation. UNION CARBIDE CORP. 21 Aug., 1969 [22 Aug., 1968], No. 41755/69. Heading BIB. [Also in Division C2] A glycol of the formula: in which R is H, CH 3  or C 2 H 5  and n is 1, 2, 3, or 4, is purified by feeding the impure glycol into a fractionating column wherein it is distilled under reflux in the presence of water so that there is at least 40% by weight of water at the glycol feed point and in part of the lower section of the column, the pressure being maintained at a value from 50 to 760mm Hg absolute, whereby the impurities distil off with water, and recovering the purified glycol from the bottoms fraction by distillation in a further column. If the impure glycol contains hydrolyzable impurities, a mineral acid is added to the first column in order to maintain the liquid in the lower section at a pH between 2 and 5; but the pH of the bottoms fraction is adjusted to a pH greater than 7 prior to further distillation. An example relates to the purification of spent monoethylene glycol containing terephthalic acid, terephthalic ester and carbonyl compounds. The spent glycol was mixed with an equal amount of ion-exchanged water and introduced as hot feed (75‹C) to the 10th tray (above the kettle) of a 20-tray oldershaw column. The bottoms fraction, consisting essentially of dry monoethylene glycol and minor amounts of diethylene glycol and triethylene glycol, was introduced to the 5th tray of a 15-tray oldershaw column. Purified monoethylene glycol was withdrawn as a liquid sidestream from the 10th tray. Other examples relate to the purification of diethylene glycol containing typical impurities generated during the manufacture of the glycol.

The probe 1, in the form of a solid cylindrical core sharpened at one end and surrounded by a tubular envelope carrying the electrodes, is secured at the opposite end to a casing carrying a pointer instrument and lamps, Figs.1 and 4 (not shown). As the probe passes through the carcass the bridge becomes unbalanced every time the current path extends in a different layer to that of the current paths 8, 9, a telescopic measuring rule mounted on the probe allowing the depth of penetration to be measured. In an alternative arrangement the probe is provided with a plurality of electrodes distributed evenly over a length of the probe corresponding at least to the maximum thickness of the carcass, Fig.3 (not shown) and each connected to a respective terminal. A three contact arm switch successively connects three electrodes into a common or individual bridge circuit. The desired thickness values are obtained as the number of switching stages between positions of unbalance and the spacing of the electrodes instead of the measuring rule. The electrodes may be helical. The measurement and recording may be automatic, Fig. 5 (not shown) in which case a transducer generating an electrical signal for controlling the recorder in dependence on the pentration is mounted on the probe.
