Patent GB-931818-A (GB)
Title: Improvements relating to mills
Inventor: TOLLOW FREDERICK SIDNEY
IPC: B02C15/12
Filed: 1961-05-11
Abstract: 931,818. Ball-and-ring mills. BABCOCK & WILCOX Ltd. May 9, 1962 [May 11, 1961], No. 17317/61. Class 59. [Also in Groups XXIX and XXX] A mill, in which an elastic fluid carries the ground material to a classifier 20 returning oversize particles to the grinding zone for regrinding, has a valve device 32 disposed between the classifier and the grinding zone and consisting of a series of closely-adjacent members 38 pivoted at their upper ends and gravity-biased to overlapping positions to prevent passage of the elastic fluid and movable from these closed positions by the pressure of the oversize particles to effect discharge. As shown in Figs. 3 and 5, inner and outer members 38A, 38B are mounted on a ring 39 which is supported around the lower end of the classifier by webs 33 and a skirt ring 31. Material fed down a central duct 19 is directed, together with rejected material, to the grinding zone between an upper ring 8, which is urged downwardly by hydraulically-operated levers 11, and a lower ring 7 carried by a rotary table 6. Air supplied at 13 is directed upwardly through a throat 17 to carry ground material to the inlet 21 of the classifier. The classifier is provided with pivotable vanes 24 which can be set in the required angular position for whirling the material to cause oversize particles to fall out of suspension but allow suitably ground material to flow through an adjustable outlet 27. The oversize particles fall on to the frustoconical wall 22, Fig. 1, and build up on the bottom wall 36 of the valve device until, under gravity, they push open the members 38 and pass to the grinding zone.

Title: Automatic adjusting mechanism for brakes
IPC: F16D65/56
Filed: 1966-04-20
Abstract: 1,106,560. Internal shoe drum brakes. WAGNER ELECTRIC CORPORATION. 20 April, 1966 [26 April, 1965], No. 17365/66. Heading F2E. In an internal shoe drum brake of the doubleacting two-leading shoe type having hydraulic cylinders 9, 9a disposed at opposite ends of shoes 4, 4a and anchoring devices co-operating with both ends of the shoes, one of the anchoring devices for each shoe is automatically adjustable to compensate for lining wear by means comprising a screw 19 (for the shoe 4) which bears against the shoe web and is engaged in a threaded bore 20 of a housing 16 secured to the backing plate 2, the housing 16 having an extension which is slotted to receive the shoe web and which has a further, transverse, slot 23 accommodating a star wheel 21 having a splined connection with the screw 19. The teeth of the star wheel 21 are slipped by a pawl during braking in the reverse direction of the vehicle wheel to which the brake is to be fitted, when lining wear is substantial, by operation of an adjusting member 50 in the form of a two-armed lever having one arm providing the pawl which engages the star wheel, and a second arm which is connected by a rod 51 to one arm of a second lever 39 pivoted on an extension of a slotted pin 13 forming the other anchoring device for the shoe 4, a rod 42 in turn connecting the second lever to the shoe web. A spring 61 for returning the adjusting lever, to rotate the star wheel and thus effect brake adjustment, is connected between a fixed pin 63 and a lug on the member 50. The spring 61 does not, however, return the adjusting lever on release of the brake, since the shoe continues to bear on the screw, causing sufficient friction to prevent this. Instead, by providing lost-motion between the rod 51 and the adjusting lever 50, the second lever 39 is allowed to return without affecting the operation of the adjusting lever, the latter returning to effect brake adjustment during a subsequent brake application in the forward direction of rotation (indicated by the arrow), during which the shoe 4 leaves the upper anchoring device thereby allowing the screw 19 to be rotated. The shoes 4, 4a are held against lateral movement by studs 33, 33a, nuts 35, 35a and washers 32, 32a co-operating with slots in the shoe webs, and four shoe return springs 15, 15a, 36, 36a are provided, the springs 15, 15a being stronger than the springs 36, 36a to prevent the shoes leaving the anchor pins 13, 13a during forward braking. The housing 16 is formed integrally with a support 12 carrying the anchor pin 13a for the other shoe 4a and similarly a support 12a integral with the housing 16a of the adjustable anchoring device for the shoe 4a carries the anchor pin 13. The star wheels 21, 21a of the two adjusters may be rotated manually by insertion of a tool through holes in the backing plate.

This hole is of such a size as to provide a stable capillary membrane 26, Fig. 3, between the gas in the respective cell 20 and the liquid 12 enclosed by wall 22. The pressure of the gas on membrane 26 is sufficient to support the liquid 12. The structure 18 may be of polyimide, Mylar, Nomex, nylon or plastics impregnated kraft paper, and the cover 22 may be made of 1 mil. Mylar film, plastics impregnated glass fibre cloth, or 1 mil. Kapton film. The cells may be filled with convection reducing material such as loose polystyrafoam chips, rock wool fibres, glass fibre, ceramic felt, shredded paper or expanded pearlite, with radiation preventing foils of aluminium foil, aluminized Mylar or aluminized Kapton (Figs. 4 and 5, not shown).

Title: Improvements in or relating to electric cables
Inventor: JORDAN REGINALD JOHN
IPC: H01B7/32
Filed: 1965-04-26
Abstract: 1,142,612. Cable insulation. PIRELLI GENERAL CABLE WORKS Ltd. 9 March, 1966 [26 April, 1965], No. 17478/65. Heading H1A. To locate areas of overheating in a cable there is provided throughout the length of the cable a coaxial pair system which includes an insulating spacing medium which is in a first non- gaseous phase at normal cable temperatures and is in a second gaseous phase at higher abnormal cable temperatures, at which higher abnormal temperatures a significant change in the permittivity of the insulating medium is exhibited. The hot spot in the cable where this change in permittivity has occurred may be located by high frequency pulse fault locating techniques. In an example given the insulating medium is carbon tetrachloride which boils at 77‹ C. and exhibits considerable change in permittivity due to the transition from liquid to vapour phase.
