Title: Anodic oxidation on Al or Al alloys
Inventor: OKUBO KEIGO
IPC: C25D11/12
Filed: 1983-10-24
Abstract: A method in which a coloured anodic oxidation coating is formed on a surface of a material comprising aluminium to which an alloying element is added or an aluminium alloy, the alloying element developing a colour upon reaction with a sulphur compound, by chemically forming an anodic coating by passage of an electric current through an electrolyte containing either or both of sulphuric acid and an and organic acid is described. The method comprises the steps of:   (a) primary chemical production utilizing an alternating current (Figure 1A) with a short negative reversing period in each cycle, and   (b) secondary chemical production comprising subsequently utilizing in the same electrolyte an alternating current (Figure 1B) of a longer negative reversing period than that of step (a) for a relatively short time, whereby an anodic oxidation coating is formed on the surface with enhanced colour and hardness. d

Title: Process for the conversion of corrinoids produced by microorganisms into cyanocorrinoids
Inventor: KELEMEN DR AGNES
IPC: C12R1/15
Filed: 1984-10-04
Abstract: Cyanocorrinoids, substantially uncontaminated by free cyanide ions, can be prepared by a process wherein hydroxycorrinoids or sulfitocorrinoids are treated with cyanide ions while bound to an adsorbent or cation-exchange resin and the resulting cyanocorrinoids are eluted, following washing of the adsorbent or cation-exchanger, e.g. with water, to remove unreacted cyanide ions. In this process. cyanide ions can be used in a much lower amount than in known processes for the preparation of cyanocorrinoids.

Title: Dual rotating stretch wrapping apparatus and process
Inventor: LANCASTER PATRICK RAYFIELD
IPC: B65B11/58
Filed: 1985-02-22
Abstract: There is disclosed an apparatus and process for high speed continuous stretch wrapping of uniform loads, in which a first web is wound in a first direction about the being-conveyed load to from a first helical stretched wrap and a second web is wound in a direction opposite the first direction about the load to form a second helical stretched wrap of opposite bias. This dual wrap nullifies the disabling effects of helical wrap bias when a single wrap is applied to a moving load, and produces a longitudinal containment force after film web recovery overtime on leading and trailing ends of the load. In the apparatus, two wrapping stations 36, 436 are provided together with a wrapping conveyor assembly 34 which carries the film web wrapped around the load and conveyor through the two stations. Each station includes a dispensing ring on which a film roll and an elongation mechanism are mounted, a drive motor to rotate the ring and means to drive the elongation mechanism to draw film web from the roll and stretch the same beyond its yield point prior to wrapping. <IMAGE>

Title: Method of manufacturing a reinforced flexible electrical connectors
Inventor: KNIGHT ROBERT
IPC: H01B7/08
Filed: 1985-08-30
Abstract: A flexible electrical connector is used to join two rigid electrical components and is of insulating material 14 bearing conductive tracks 16. Often these connectors tends to test and this can be difficult and expensive to remedy. By including a reinforcing thread 18 along an edge of the connector, these tears tend to be stopped. In one method for laying down the thread 18, it is fed through an aperture 20 in an extension 21 of an applicator 17. The extension 21 is arranged to be heated during operation, such that as the applicator is drawn across the surface of the insulating material the path it takes is heated causing thermosetting adhesive 15 on the insulating layer to soften and hence cause the member 18 to stick in position. In another method (Fig. 3) a heating effect is provided by causing the extension to vibrate whereby the adhesive is frictionally heated.   <IMAGE>

Title: Ladle for holding molten material
Inventor: URAM ZANE STUART
IPC: B22D41/04
Filed: 1985-10-04
Abstract: A ladle (12) has above its rim (24) a pair of upstanding ears (16) which in use are above the level of molten metal which can be poured from the spout (30). The outer faces of the ears have indentations (36) into which fit protrusions (44) of a gripper apparatus (14).

Title: Circular weft knitting machine
Inventor: TIBBALS JR EDWARD CAMP
IPC: D04B15/99
Filed: 1986-11-20
Abstract: A circular knitting machine has needles, preferably compound needles 84, with flexible intermediate portions which allow selective displacement of butts into cam tracks, 340,346 recessed into the inner surface of an external stationary sleeve 86. The flexible portion normally biases the butts out of the tracks 340,346 and further butts on the needle element and its closing element into cam tracks 352,354 recessed in an internal stationary sleeve 78. For selection the butt ends of the elements are cammed outwardly against magnetic selectors 400 having a pair of permanent magnets with an electromagnet therebetween which can be selectively pulsed to negate the permanent magnet flux and release the elements. The cam tracks are symmetrical about the feed positions and about points halfway between the feeds, at which latter points the selectors 400 are located, to enable operation in both directions of rotation. <IMAGE>

Title: Means for preventing twist of a connecting line for a temperature probe in a microwave range
Inventor: LEE HEE JIN
IPC: H05B6/80
Filed: 1986-11-28
Abstract: Means for preventing twist of a connecting line for a temperature probe in a microwave range is disclosed. An electromagnet 20 which is automatically actuated according to a connecting rod being inserted into a jack 42 is provided so that a steel piece 18b of an activating lever 18 is attracted thereto to result in a stopping pin 18a of the activating lever being outwardly moved away from a disk 22 having a protrusion 22a at its peripheral surface and mounted on a rotating axis of a synchronous motor 16 driving turntable 10. As a result if the probe line is mounted in jack 42 pin 18a engages protrusion 22a when disk 22 rotates. When this occurs motor 16 reverses direction and accordingly line 48 is not twisted. If the probe is removed from jack 42 lever 18 is actuated and pin 18a moved clear of protrusion 22a and consequently turntable 10 can rotate in a single direction. <IMAGE>
