Title: Grinding machine including a sliding unit
IPC: B23Q11/00
Filed: 1974-09-16
Abstract: 1476522 Grinding VOUMARD MACHINES CO SA 16 Sept 1974 [17 Sept 1973] 41090/84 Heading B3D A sliding unit for a grinding machine comprises a block table 1 having parallel upper and lower faces and of a height to enable it to be placed on a base table 6 of the machine and carry on its upper face an operating arrangement of the grinding machine, and a slide drive mechanism within the table to cause the arrangement to carry out, under direct manual control or under indirect (manual or automatic) control, by means of an operator, functional movements of the grinding machine in the direction of slide of the slide mechanism. The unit may be used in an internal grinding machine and the functional movements consist of plunge cut and coarse feed movements, engagement/disengagement consisting of movement within and retraction from the workpiece, and taking up of wear of the wheel. The unit has a cast base 2 which may be secured to a base-plate 3 and is mounted on the table 6 of the grinding machine. A lever 7 consists of two parts 7a, 7c which are secured together and mounted on a pivot 8, and a part 7b which is secured to parts 7a, 7c and around which a roller 11 is supported by a roller bearing. A pivot 9 on the lever supports a further roller 10, the distance of the axis of roller 10 from pivot 8 being five times that of the axis of roller 11 from the pivot 8. The plunge cut and coarse-feed movement is produced by a stepping motor 12 which is secured to the base 2 and rotates a rod 15 mounted in play-eliminating means 18 and having screw-threaded engagement with a micrometer sleeve 19. A head 22 of the sleeve engages the roller 10. The upper portion of the unit consists of a plate 25 slidable in crossed roller bearings 28 on the base 2, the plate forming a table for the grinding wheel support. A sleeve 26 is secured to the table and connected to a rod 27 having a piston slidable in a cylinder 29, fluid pressure supplied to one or other side of the piston causing the engagement or disengagement movement of the table. The disengagement position is determined by a stop 35 adjustable by a manually-operated drum 36. The engagement position is determined by engagement of the rod 27 with the roller 11 of lever 7, the movement of which by the stepping motor 12 effects the plunge feed which may be in steps of ¢ micron on the radius of the workpiece. Wear or dressing of the grinding wheel is taken up by advancing the sleeve 26 relative to the rod 27 by relative rotation of the sleeve 47 which carries sleeve 26 and has a micrometer thread engagement with the rod 27, the sleeve 47 being rotatable by a toothed-belt drive 42 from a stepping motor 40. The motor can be operated automatically or by hand-operated drum 44.

Abstract: 949,203. Overhead conveyers. FISHER & LUDLOW Ltd. Feb. 27, 1961, No. 40312/59. Addition to 819,343. Heading B7L. In a conveying installation in which loadcarrying trolleys are propelled along a track by driving elements projecting from a driving chain there is provided at one or more locations on the installation a plurality of carrier drive disengaging elements, a plurality of actuating elements operatively connected to a carrier drive disengaging element situated rearwardly thereof in relation to the direction of advancement of the carriers by the driving element, and arresting members on or associated with each carrier drive element for arresting the carriers within longitudinal limits such that an arrested carrier is effective to move the disengagement element next in rear thereof into its operative position to ensure arrest of the next newly arrived carrier, each actuating element being so arranged as to be operated by a carrier which is being pushed in front of the succeeding carrier before the latter has advanced beyond the carrier drive disengaging element associated with the actuating element, whereby the last disengaging element is then effective at least to disengage the driving element from the succeeding carrier. In the arrangement shown a carrier 13a is pushed along a track 12 by a driving dog 15 depending from a chain 11 running on a overhead track 10. On arrival at a stopping point along the track 12 the leading carrier 13a engages an element 38 to pivot a stop 20 and a carrier drive disengaging element 23 into the path of the succeeding carrier 13b. The stop 20 prevents further forward movement of the carrier 13b and the element 23 is engaged by cam follower 32 to lift the driving dog 15 out of driving engagement with the carrier 13b. Specifications 875,082, 875,083, 949,204 and 949,205 also are referred to.

Abstract: 1340019 Chocolate fillings KARLSCHLOSS ANSTALT 8 Sept 1972 [8 Sept 1971] 41904/72 Heading A2B Confectionery is made by preparing a hot non-supersaturated sugar solution (e.g. saccharose solution at 88‹C) which has a saturation point (58‹C) above the melting point of chocolate (typical melting point is 34‹C), rendering the solution supersaturated by cooling it to at least 25‹C below the melting point of chololate (preferably to between -10‹C and 0‹C), introducing the solution at this temperature into preformed chocolate shells, and allowing it to rise to ambient temperature, when crystallisation occurs. The saturation point of the sugar solution is preferably at least 40‹C. The chocolate shell is closed by a chocolate cover after the solution is introduced. Flavourings (e.g. coffee, brandy or cognac) may be added to the sugar solution before cooling. Apparatus for continuous preparation of the confectionery may comprise a steel band conveyer cooled by spraying with brine at -15‹C to -20‹C, and metering piston pumps with downwardly directed nozzles. The cooled sugar solution is removed from the steel band by a scraper blade. The solution is initially cooled by 40‹C in two seconds and total cooling time is about half a minute. The sugar solution layer on the band is 2-10 mm. thick. Cooling may alternatively be done batchwise. The confectionery is packaged and stored in a conditioning chamber at 10‹C-25‹C for 2-3 days, turning at least once for uniform crystallisation.

A motion picture projector comprises a shiftable transmission connecting a film advancing mechanism with a unidirectional motor, manually operable means to start the motor and control the shiftable transmission, and means to change the speed of film advance to either of two different speeds, interlocking means being provided to prevent speed change when the transmission is in a neutral position. In the cine projector shown in Fig 1, a circular shutter 12 and film feed means 11 are driven by means of a belt 29 coupled to a driven pulley 22. Pulley 22 is movable by means of pivoted lever 19 so that it is coupled to pulley 18 or by a belt 25 for forward or backwards drive of pulley 22j pulley 18 being connected to a unidirectional motor. In an intermediate non operated position, pulley 22, 18 are uncoupled. Belt 29 may engage one of two different diameter grooves in pulley 22 for forward drive (corresponding to different film speeds) and is controlled by means of a manually operated forked lever system 37, 36. A lever 19 is connected to lever 55 which is in turn connected by over centre spring toggle system to a lever 51. The lever 19 and drive motor are both operated by means of a five positioned manually operated lever 37 connected by gears 42,43 to a switch means 45 of the electric motor and by cam 48 (Fig 7) connected to gear 43, and by pivotted cam follower lever 46 to lever 51 of the lever 19 control means. The five positions of lever 37, switch 45 and cam 48 are "off", "forward", "forward with lamp", "reverse", "reverse with lamp"; the position "with lamp" having no adjusting effects on lever 19. To lock the film speed adjusting lever 36 during reverse drive a pivoted lever 67, controlled by cam 48 through lever 46, is provided. In the "reverse" or "off" position on end of lever 67 engages slot 72 or 73 of lever 36 and prevents lateral movement when as in the "forward" positions the end of the lever 67 is in slot 71 and lever 36 is free to move.
