Title: Device for taking up wear for a disc brake and a brake including said device
IPC: F16D65/097
Filed: 1972-06-06
Abstract: 1326860 Fluid-and-mechanical spot-type disc brakes; wear adjusting PONT-A-MOUSSON SA 6 June 1972 [25 June 1971] 26242/72 Heading F2E An automatic wear-adjusting device in a spot-type disc brake includes a piston 7, Fig. 5, constituting a nut, a screw 12 having a smooth cylindrical bearing portion 13 located between its threaded portion and its (larger) head 14, a ring 17 slidable on portion 13 but constrained to rotate with the screw by engagement of apertures 16 in the ring with studs 15 extending from screw head 14, and a spring-loaded finger member 19 having teeth 25, Fig. 2, which cooperate with equivalent teeth 18, of saw-tooth section and oriented obliquely to the ring axis, provided on the ring. On brake application, hydraulic fluid introduced at 32 forces piston 30 leftwards, and, with it, screw 12, ring 17 and piston 7, all without rotation; brake pad 3 is applied by reaction on sliding caliper 2. Leftward movement of ring 17 causes finger member 19 to ride up the teeth 18, but if pad wear is only sufficient to cause ring 17 to move a distance not exceeding m, Fig. 4, the components return to their former positions on release of fluid pressure. In the event of excessive pad wear, ring 17 may move a distant L greater than m, Fig. 4, whereupon ring 17 jumps one tooth relative to finger member 19. On release, piston 7 and screw 12 are initially still under load, so mutual rotation is not possible, and because piston 7 is not rotatable, screw 12 cannot rotate either; ring 17 is also prevented from rotating by studs 15, so it is held axially at this stage. When piston 7 and screw 12 have returned sufficiently far for pressure between them to be relieved, horizontal springs 29, Fig. 5, acting through fingers 26, urge ring 17 to the right; ring 17 is constrained to rotate by finger member 19, so screw 12 is rotated, whereupon piston 7 is urged to the left, taking up the wear. In Fig. 1 (not shown) piston 30 is normally in contact with a plug closing bore portion 6, but in Fig. 5, piston 30 may alternatively be operated by rotatable arm-screw assembly 33, 34 in fixed nut 35, via simple ball-bearing assembly 37. The wear adjusting device operates, when necessary, exactly as before.
Patent GB-793760-A (GB)
Title: Organic titanium compounds
IPC: C07F7/00
Filed: 1956-08-28
Abstract: Solutions of chelate complexes of titanium with a -hydroxy carboxylic acids are stabilized to alkaline conditions, heating and dilution by the addition of a polyol containing from three to eight hydroxy groups on adjacent carbon atoms.  The ratio of titanium salt to polyol is from 1:0.1 to 1:2, the titanium salt containing 1-4 mols. of a -hydroxy acid per gram atom of Ti. The a -hydroxy carboxylic acid may be a simple compound such as glycolic, lactic or a -hydroxybutyric acid, or may contain aromatic rings, e.g. mandelic acid, or may contain other carboxyl or hydroxyl groups, e.g. malic, citric or tartaric acids. Suitable polyols are polyhydroxy aliphatic or alicyclic alcohols or their derivatives, especially the six-carbon straight-chain hexahydroxy alcohols such as sorbitol, mannitol, and dulcitol; hexoses such as glucose and mannose; and hexose derivatives such as glucosides, glucamines and glyconic acids.  Such stabilized solutions are used in the textile, leather and cosmetic industries, e.g. in the dyeing of cloth.  Examples describe the stabilization of solutions of titanium monolactate, dilactate, diglycolate, monomandelate, malate, citrate and tetralactate with sorbitol, mannitol, dulcitol, inositol, glycerol, N-methylglucamine, methylglucoside, gluconic acid and erythritol.ALSO:Aqueous solutions of the chelate complexes of titanium with a -hydroxycarboxylic acids, stabilized to alkaline conditions, heat and dilution by the addition of a polyol containing from 3 to 8 hydroxy groups on adjacent carbon atoms, are used in dyeing cloth.  Thus a molar solution of titanium monolactate containing 0.5 mol. of sorbitol per gram molecule of titanium monolactate is used as a mordant in dyeing nylon cloth with a blue direct dye.

Title: Accidental-motion compensation with collimated light
IPC: G02B27/64
Filed: 1968-06-04
Abstract: 1,235,175. Stabilized optical systems. OPTICAL RESEARCH & DEVELOPMENT CORP. June 4, 1968 [June 1, 1967], No.26627/68. Heading G2J. An accidental motion compensator for optical systems such as cameras telescopes or binoculars comprises a housing 32 including an approximately two power erecting telescope 31, inertially mounted reflecting means 37 to reflect collimated light from the telescope along a line parallel to the incoming beam, inertial means 41 mounted to the reflecting means arranged to maintain the reflecting means 37 in a substantially fixed angular alignment irrespective of small angular displacements of the housing, and rigidly mounted optical means 42 to form an image from the light reflected from the reflecting means. Light parallel to the axis of the telescope enters a prism 37 mounted for free movement about two mutually perpendicular axes through a point 39 and stabilized by a unit 41 comprising a free gyroscope with controlled processing means so that the element 37 is stabilized for small movement of the housing 32 but follows the housing for large movements. The light is then directed to a lens 42 and triple reflective prism 44 and is focused in a stabilized image plane 43. The pivot axes may be displaced from each other. Upon a small deviation of the optic axis the magnification of the telescope causes light to be incident on the prism at an angle # to the surface. It is reflected at an angle # to the surface and thus perpendicular to the front surface of the second prism from which it is reflected on to the image plane 43 as though no rotation had taken place. In a camera a second reversing prism is not necessary, but normally at least one is employed for parity correction. In an alternative embodiment three mirrors fixed relative to one another and moveable as a unit may be used instead of the triple reflecting prism.
