Title: Improvements in and relating to grinding machines
IPC: B24B5/06
Filed: 1946-04-04
Abstract: 634,156. Internal grinding machines. AKTIEBOLAGET LINHAM. April 4, 1946, No. 10432. Convention date, March 13, 1944. [Class 60] A method of grinding the inner surface of hollow work-pieces, by means of two coaxiallymounted rotating grinding tools operating on a work-piece to which is imparted a rotary and an axially reciprocating motion, consists in adjusting the grinding tools in an axial direction relative to each other and to the work-piece in such a manner that said grinding tools are located at a distance from each other which is less than the length of the inner surface of the work-piece, and reciprocating the work-piece over a distance such that during the grinding operation both grinding tools remain constantly in contact with the surface to be ground. Grinding spindles 1, 2, Fig. 1, carrying rollers 3, 4 are mounted in cylindrical housings 5, 6 axially displaceable in guide bearings in brackets 7, 8 carried by a plate 9 'movable transversely to the axis of the grinding spindles. The latter are rotated by compressed air turbines 10, 11 supplied through flexible pipes 12, 13., The housings 5, 6 are moved axially by bell-crank levers 14, 15 ; for accurate positioning of the grinding rollers when moved to their operative positions, the housings carry stop screws 20, 21. When the rollers have been moved into their operative positions, each housing is secured by a pair of clamps, each comprising a piston-like member 23, Figs. 3, 4, and a sleeve 24 which are forced together to engage the housing 6. The two pistons 23 of the pair of clamps have tension rods 25 with nuts 28 bearing on the ends of a bar 27, and the ends of a bar 26 bear on the sleeves 24 ; a central screw 30 operated by a handle 32 forces the bars 26, 27 apart, thus simultaneously actuating both clamps and distributing the clamping pressure. The arrangement ensures 'that the coaxial alignment of the spindles is maintained. Stop pins 33 co-operating with the handles 32 limit the clamping pressure. The work is carried by a chuck rotatably mounted in the head 36 of a holder 37 which is pivotally mounted so that the chuck can be swung into and out of the working position; the chuck is driven by a belt 45 from a pulley 47 driven by a motor (not shown) through worm-wheel 48 and worm 49, the shaft of the latter extending through a slot 50 in the wall of the holder 37 and passing through a hole in a fixed ring 54 which covers the slot. A trueing diamond 53 is provided on the holder 37 opposite the chuck.

Title: Improvements in door spring and check devices
IPC: E05F3/16
Filed: 1922-04-13
Abstract: 178,833. Mukden, F. G., (Assignee of Gerpat Ges f³r Erfindungen und Patentverwertung). April 19, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Operating doors by springs; checks.-A doorclosing spring is fitted with a piston in which are mounted cam-operated friction shoes which are forced into contact with the walls of the cylinder as the door is moved into the closed position. The piston 11 is mounted on a rod 14 on which is coiled the closing spring 24, and pivotally mounted in slots 15 of the piston are cam members 17, 18 in contact with movable friction blocks 21, 22. During the opening of the door when the spring 24 is being compressed, the end b of slot 28 in the rod 14 engages the cam members to release the friction blocks from engagement with the cylinder walls 9, 10, as shown in Fig. 4. During the door-closing operation, the abutment a at the other end of the slot 28 is forced against the cam members to oscillate them into a position whereby the friction blocks make contact with the cylinder walls, thus checking the closing operation. This braking action may be regulated by adjusting the compression of the spring 26 on the end of the rod 14. The frictional members are formed of gradually reduced thickness so that the door may close freely at the end of the closing movement.

Title: Improved method of and apparatus for gumming the flaps of envelopes or the like
IPC: B31B19/00
Filed: 1940-06-20
Abstract: 542,662. Gumming envelope flaps. BEASLEY, H. H., FRENCH, G. W., and BEASLEY, FRENCH & CO., Ltd. June 20, 1940, No. 10647. [Class 95] A machine for making envelopes or bags is provided, at its delivery end, with apparatus for gumming the flaps in a continuous stream, and the apparatus comprises a gum applying device and conveyers adapted to receive the envelopes in a continuous stream from the machine and to convey them, in overlapping relationship, to the gum applying device, with the areas of the flaps to be gummed exposed. Envelopes, from the envelope-making machine, are fed in a continuous stream 5, overlapping so as to expose their flaps, between a conveyer belt 6 and an endless belt 7. They are then carried between conveyers 11, 12, and enter between the lower track of a conveyer 17 and the upper track of an endless gumming brush 18. The conveyer 17 comprises two laterally spaced tapes or belts which engage the marginal portions of the envelopes. Parallel guide rails 20 support the envelopes as they issue from the gumming stage, and direct them on to a tensionadjustable endless conveyer 21, and thence to a conveyer 24. Heaters may be arranged in juxtaposition to the tracks of the conveyers. The conveyer 24 is preferably arranged so that its upper surface is barred transversely, and guides may be arranged along each edge of the conveyer, to engage the edges of the envelopes which are thereby bent or bowed, thereby preventing curling of the gummed flaps. The rate of travel of the brush 18 is greater than that of the chain of envelopes, and the rate of travel of the conveyer 21 is greater than that of the envelopes at the gumming stage, so that all the gummed areas are adequately separated. Cams 30 may be provided for adjustment of the frame 1, and also for lifting the conveyer 17 clear of the endless brush 18. Specifications 542,600 and 542,661, [Group XVII], are referred to.

Title: Oil stain resistant colour coated mineral granules
IPC: E04D5/12
Filed: 1957-04-05
Abstract: Mineral granules having a well-bonded weather-resistant colour coating over the surface thereof are provided with a stable minute water-insoluble second coating formed from an oleophobic fluorocarbon sizing agent to render them oil stain resistant and capable of forming an adherent bond with a bituminous substrate. The granules may be coated with a pigment and binder solution, dried and fired to a tack-free abrasion-resistant state, treated while still hot with a dilute aqueous aluminium chloride solution to pickle and partially to cool them, and then coated with an oleophobic fluorocarbon sizing agent dilutely contained in an aqueous vehicle, the said vehicle being dried from the granule surfaces principally by residual heat remaining in the granules. Oleophobic fluorocarbon sizing agents are carbon compounds which are characterized by having in the molecule one or more highly fluorinated or perfluorinated terminal chains or side chains. Preferred compounds are the fluorocarbon monocarboxylic acids and certain derivatives thereof.  These compounds can be employed in the form of the free acid, the metal or ammonium salts of the acid, or as polyvalent metal co-ordination complexes.  Examples are given of the use as sizing agents of (1) N-methyl N-perfluorooctanesulphonyl glycine and (2) the chromium complex of perfluorooctanoic acid applied to coloured granules of syenite. The treated granules may be employed in the preparation of bituminous roll roofing and asphalt shingles, being applied as a layer or coating to the heated asphalt-impregnated and asphalt-coated fibrous base sheet material and pressed into place by means of rolls.  The resistance of roofing materials prepared in this way to oil staining and to abrasion is compared with that of similar material which has not been treated with the fluorocarbon sizing agent.  Specifications 686,678, 703,435, 712,784, 857,334, 857,335, 865,393 and U.S.A. Specification 2,614,051 are referred to.
