Title: A process for treating articles and masses obtained from phenolaldehyde condensation products
IPC: C08L61/10
Filed: 1927-02-18
Abstract: 292,636. Petroff, G. Feb. 18, 1927. Phenol-aldehyde condensation products.- Articles and masses obtained from phenol-aldehyde condensation products (alone or mixed with fillers) in the infusible and insoluble state are coloured and/or protected against atmospheric influences and the action of light by treating them with solutions of colouring agents and/or of phenolic substances in alcohols, aldehydes, lower ketones, volatile organic acids, or mixtures thereof. Suitable phenolic substances are hydroquinone, pyrogallol, gallic acid, tannin, and aminophenols. It is preferred to include in the treating solution a stable resin, such as shellac, or a cellulose ether, and when colouring is effected with a water-soluble colouring matter, it is preferred also to fix the colour by subsequent boiling in aqueous solutions of suitable fixing agents, such as bichromates, alum, ferric or copper salts, Glauber's salt, or tannin. In one example, an article made from a phenol-aldehyde. condensation product is kept at ordinary temperature for 20 hours in an alcoholic solution of Diamond Green B, and in another example, a hot alcoholic solution of the, same dvestuff and shellac is used. In a further example, the article is boiled in an alcoholic solution of Fast Brown Ont. and hydroquinone.

Patent GB-999654-A (GB)
Title: Improvements in or relating to multi-speed transmission hubs
IPC: B62M11/14
Filed: 1963-02-05
Abstract: 999,654. Variable-speed epicyclic gear. FICHTEL & SACHS A.G. Feb. 5, 1963 [Feb. 7, 1962], No. 4700/63. Addition to 937,633. Heading F2D. In a change-speed hub gear without backpedal braking, change of ratio is effected by backpedalling which moves a stop body against a stationary stop which has an overload disconnecting arrangement with respect to a stationary hub part. In a two-speed hub gear, drive from a sprocket 29 is transmitted to a planet carrier 4 having planet gears 12 meshing with a sun gear 13, rigid with the wheel spindle 1, and with a ring gear 14 having an extension formed with internal ratchet teeth 19. The planet carrier 4 also drives a drive sleeve 9, freely rotatable on spindle 1, on which is rotatably mounted a pawl carrier 15 having pawls 17 engaging the teeth of the carrier 4 and opposite handed pawls 16 engaging a locking ring 20 in lost-motion connection with the hub shell 7. The pawl carrier 15 is in backpedalling connection by a clamping spring 18 with a movable stop body 22 in screw-thread connection 26 with the sleeve 9, such that on backpedalling the stop body 22 moves axially to contact a fixed stop 27 and limit the backpedal movement to that necessary for ratio change. In direct drive, the drive passes from the sprocket 29 to carrier 4, driving sleeve 9 and pawls 50 on the stop-body 22 to the hub shell 7. On backpedalling the ring gear rotates while the pawl carrier 15 is held by the spring 18, allowing the pawls 16 to move into a deeper part of the teeth 19 and engage the teeth of the locking ring 20 to drive through the planet gears and ring gear to the hub shell. The stop 27 is in torque limiting frictional engagement through a friction strip 28 with the stationary hub part 3 to prevent jamming of the stop 22 on excess backpedalling. In modifications, the stop 27 has torque limiting means comprising ball detents, torque disengaging profile teeth and axially disengageable teeth, all of which are spring loaded.

The strips 2, 3, sewn to the bat by rows of stitching 4, are preferably of paper. Two lines of stitching may be used to each strip, so that the finished material may if desired be divided down the centre of the strips. The covering sheet 5 may be of paper or other material, applied to one or both sides of the base by means of an adhesive such as a solution of sodium silicate, asphalt, or glue.

Abstract: 1,016,044. Ticket validating apparatus. R. C. RINGHOLZ. Feb. 13, 1964 [July 25, 1963], No. 6045/64. Heading G4T. A ticket validating apparatus has means for preventing the insertion of further tickets for validation after a predetermined number have been validated. The apparatus is for use in shops &c. which are situated in a restricted parking area and is arranged to print validation markings on a car park ticket or a bus or taxi ticket to indicate that an association to which the shop keeper belongs will pay the cost of the ticket to the car park attendant &c. As described, a ticket to be validated is inserted in a slot 12 and its lower edge is pressed against fingers 58A, 60A so that a print sector 60 bearing a porous ink bearing print plate, and an anvil or backing sector 64 are pivoted downwardly against the action of a spring 78. The sectors 60, 64 grip the ticket to prevent its withdrawal until the sectors have been lowered the full printing distance and raised again under the control of a full stroke pawl 82. The pawl operates a buzzer circuit to indicate to the shop keeper that the apparatus is being used. Each time the sector 60 is depressed an escapement 86 is operated to advance an escapement wheel 46 connected to a sprocket drive which advances an edge punched indicator tape past an aperture 14. The tape passes from an idler drum 44 to a spring or motor-driven drum 32 and indicates how many validations are left before the shop keeper has to pay more money to the association. The machine can be opened by a lock 24 in order to rewind the tape. A stop pawl 50 has a tooth 52 which is spring- biased against the tape so that as the tape end is approached, the tooth 52 drops through a stop aperture in the tape so as to project into an aperture in a sector 48 which is rigidly attached to the sector 60. Thus the sector 60 is locked so that no further tickets can be inserted.
