Title: Improvements in electrolytic condensers
IPC: H01G9/048
Filed: 1938-11-29
Abstract: 521,962. Electrolytic condenser. NAAMLOOZE VENNOOTSCHA.P PHILIPS GrLOEILAMPENFABRIEEEN. Nov. 29, 1938, No. 34735. Convention date, Dec. 2, 1937. [Classes 37 and 41] The aluminium cathode of an electrolytic condenser, for example the casing 1, on the sides in contact with the electrolyte is roughened and then plated with chromium direct on the aluminium. The roughening may be effected by etching to increase the effective surface two to five times, for example in a bath containing 10 per cent. of hydrochloric acid for five minutes, after a preliminary degreasing. After rinsing the cathode is transferred directly to a bath containing 200 grams of chromic acid and 4 grams of sulphuric acid per litre of water, the current density being about 60 amp/dm<2> at 70‹ C. and the time about 3 minutes. This gives a layer of chromium about 1Á thick. As shown the casing has fitted within it an anode 2 carried on a base 4, and has at the other end a vent comprising a projection 6 perforations in which are closed by a rubber band 7. The vent is enclosed by a cover. 9 containing absorbent material 8.

Title: Improvements relating to homing systems
Inventor: WATSON EDWARD
IPC: F41G7/22
Filed: 1956-11-13
Abstract: 1,273,521. Automatic steering control. FAIREY CO. Ltd. Feb. 13, 1958, No.34746/56. Heading G3R. A missile is guided towards a target which points infrared radiation. Deviation of the missile from the target direction causes an alteration of the radiation incident upon a photo-electric cell carried by the missile, the output of which provides a steering surfaces control signal. In the first embodiment, the target is illuminated with infrared radiation the frequency of which is charged, cyclically, between two valves. Reflected radiation is received at the missile where a moving aperature, in front of the P. E. cell, periodically exposes the cell to the radiation. The speed of the aperature is continuously adjusted by the cell output signal, to allow for target-missile angular position charges. The signal effecting movement of the aperture simultaneously effects movement of the craft control surfaces. A target-missile position charge causes a difference in the relative amplitudes of the outputs from P.E. cell at the two frequencies. In the second and third embodiments, the radiation from the target is uniform and the periodic aperture charges produce a cell pulse output the phase of which is compared with a reference to give the craft deviation measurement and control signals.

Abstract: 1420230 Making electrical connections INTERNATIONAL COMPUTERS Ltd 17 July 1974 [21 July 1973] 34867/73 Heading B3A A tool 5 for use with a channel-shaped strip connector 1 having a row of holes along a base portion for co-operation with a row of connector pins 2, includes a first plate 6 having a line of teeth 18 along one edge which are spaced so as to allow passage of the pins 2 between them, each tooth having a tapered leading edge, and a second plate 7 maintained in face-to-face relationship with the first plate and slidably secured to it so that the plates can move relatively to each other between a first position in which the teeth are retracted and a second position in which they are exposed. The arrangement is such that when the teeth are exposed they engage between side regions of the strip connector so that the holes can be manually engaged with the pins. The plate 6 is then raised until the teeth are clear of the connector while the plate 7 continues to engage it until its side regions clamp on the pins 2 and the connector is then moved into the required position on the pins. A connector may be removed by reversing the placement steps. The tool 5 is as long as the strip 1 to avoid damaging it as it is normally of thin phosphor-bronze and the tool and strip are aligned either visually or by making the hole spacing in the strip such that aligning one end of the strip with, e.g. an edge 20 of the tool, aligns the holes with the slots 17. The strip may be formed with a separate connecting jaw (22) for each pin 2, Fig. 3 (not shown), the jaws being so dimensioned that each tool engages the edges of two adjacent jaws.

Abstract: 1,119,982. Straightening. HEAD WRIGHTSON & CO. Ltd. 4 Aug., 1966 [16 Aug., 1965], No. 34985/65. Heading B3E. A roller leveller for sheet or strip metal comprises a top roll assembly 14, a bottom work assembly 16 and a plurality of series of short back-up rolls 18 or 49 operatively associated with each assembly, each series of back-up rolls of the top and/or bottom work roll assemblies being supported independently and adjusting means being associated with the support of each series of back-up rolls to effect deflection of the coacting work rolls, the adjusting means being arranged and constructed so that the extent of deflection of the work rolls decreases progressively from the work roll at the entry side of the machine to the work roll at the exit side. Each of five series of back-up rolls 18 is carried by a cradle 21 which is vertically adjustable by wedges 35, 38, being urged upwardly by springs. The cradle 21 is adjustable angularly about a bearing block 30 the arcuate bearing surface of which, centred on the axis of the last exit work roll, bears on a support block 33. The angular adjustment is effected by movement of a support block 37 at the entry side of the apparatus to move a bearing block 31 along the wedge 38. Such movement of the block 37 of each cradle may be effected by a shaft common to all the cradles, in which case the angles of the wedges 38 differ, or by independent control shafts. The resultant effect is to curve the entry work rolls but not the exit work rolls.

Abstract: 935,507. Winding yarn. MUSCHAMP TEXTILE MACHINERY (SALES) Ltd. Sept. 12, 1961 [Oct. 14, 1960], No. 35256/60. Class 120 (2). A cop winding device has a rotatable member 20 over which the yarn 19 is initially passed along a path 19b to form a bunch winding on the cop 15. The movement of the yarn causes the member 20 to rotate and this rotary movement is used to cause the member 20 to withdraw along its polar axis so that the yarn eventually drops off the member 20 to a position 19a where it is caught up in a yarn reciprocating member 17. The shaft of the member 20 may have a screw-threaded portion engageable by spring- loaded finger on the frame of the apparatus such that as the shaft is rotated by the member 20 said shaft is forced to move axially. The rotatable member 20 may be eccentrically mounted or be peripherally non-circular to effect traverse of the yarn during bunchbuilding. The cop carrier 14 is urged to the right, as by weight means, into engagement with a freely rotatable cone 16 (not shown), the function of which is to determine the finished outer diameter of the cop by causing the carrier to be pushed to the left as the package is built up.

Title: Process of preparing an iron oxide-chromium oxide mixture
IPC: C07B35/04
Filed: 1957-11-15
Abstract: Intimate mixtures of iron and chromium oxides, suitable for use as catalysts, are prepared by a process which comprises adding a water-soluble chromium-containing compound to a suspension of ferric oxide monohydrate in an aqueous solution of a ferrous salt, the suspension having a pH of less than 7, and subjecting the suspension to oxidizing conditions in contact with pieces of metallic iron at a temperature of at least 55 DEG  C.  The chromium compound may be a salt, e.g. the sulphate or chloride or a salt of an oxyacid of chromium, e.g. potassium bichromate.  The ferrous salt may be any water-soluble salt, e.g. the sulphate or chloride and the preferred pH of the solution is between 3 and 4.  The oxidizing conditions may be achieved by passing air or any other free oxygen-containing gas through the suspension or slowly introducing a water-soluble oxidizing agent, e.g. H2O2 into the suspension.  When the chromium compound has oxidizing properties it should be added slowly.  The preferred ferric oxide is goethite, a -Fe2O3.H2O, suitably in the form of 0.5 to 1 micron crystals.  The iron pieces preferably have a large surface area provided that they are still readily separable from the suspension by decantation or straining.  Clippings from 0.6 mm. iron sheet and iron turnings are very suitable.  The mixture may be used as a catalyst as obtained by the process or it may first be subjected to further treatment, e.g. dehydration, reduction, oxidation or agglomeration.  In an example, 250 g. of yellow iron oxide monohydrate and 1500 g. of 6 to 10 mm. iron sheet waste were suspended in 3 litres of an aqueous ferrous sulphate solution containing 30 g. Fe++/litre and having a pH between 3 and 4.  The suspension was heated to 60 DEG  C. and 120 g. chromic sulphate in 500 c.c. of hot water added.  100 litres/hour of air were passed through the hot suspension for 48 hours and the metallic iron was then removed from the suspension which was subsequently filtered, washed and dried to give a mixture of ferric and chromium oxide containing 7% wt. Cr2O3.
