Title: Surface treating machine
Inventor: PETERSON RUBEN OLOF
IPC: B24B31/00
Filed: 1959-12-22
Abstract: 868,189. Surface treatment. OSBORN MANUFACTURING CO. Dec. 22, 1959, No. 43543/59. Class 60. A machine for subjecting articles to a surface treatment comprises a plurality of cylindrical power driven brushes, 7, 8, 9, 10 mounted on parallel axes and arranged to define an articlereceiving trough, the brushes conjointly forming substantial portions of the sides and bottom of the trough ; the trough may be closed to form a chamber by two further rotary brushes 5, 6, mounted on axes parallel to those of the other brushes. The gaps between these brushes are substantially closed by endless belts or bands 24, 27, 28, 29,. 30, which are power-driven generally in a direction to assist the passage of articles through the machine from a shoot 33, Fig. 2, fed by a conveyer 32, to discharge at the opposite end and removal by a conveyer 34 stationary wall portions may be provided instead of the belts 29, 30 and in some cases only the bottom conveyer 24 need be provided. The motors driving, individually, the brushes and belts may be reversible so that, by changes of direction, the articles may be continuously repositioned during treatment. The passage of the work through the machine is facilitated by pivotally mounting the front end frame 1, as at 3, and tilting the trough by.lifting the rear end frame 2 by screw-jacks 4. The brushing action may be supplemented by the application of stone chips, aluminium oxide, silicon carbide, wood-chips, nut-shells, sand, rouge, pumice, shot-pellets, water detergents, or solvents. Smaller particles of abrasive material are fed from a hopper 35 and through metering brushes 37, 38, to the treatment chamber through an elongated shoot 39 from which the material is discharged together with air and liquid from ducts 40, 41, 44, 45, the mixture being projected downward with considerable force by the impeller brushes 5, 6, which are rotated at higher speeds than the other brushes ; the liquid flow may be continued after the metering- brushes 37, 38, have been stopped so that loose particles are cleared from the work prior to discharge by the conveyer belts. A continuous conveyer-screen 51 sifts the larger particles of treatment material as it leaves the bottom of the trough and deposits them in a bin 54 whence they are transferred by a bucket elevator 55 to a hopper 56 and a slowly-rotating metering brush 57 to a shoot 58 leading to the supply port of the machine. The other portion of the abrasive mixture is collected in a sump 50 and is raised by a vertical screw conveyer 46, Fig. 1, to the hopper 35. The air supplied by ducts 40, 41 may be above atmospheric pressure and an outlet vent V, Fig. 1, may be used to suck away dust and fumes from the housing 23 between the end frames 1, 2. Pneumatically-operated vibrators 61, 62, 63, Fig. 2, having upwardlyprojecting rods 65, may be provided to joggle the work-pieces on the belts during their passage through the machine ; a bar B below the underside of the conveyer belt and having limited vertical movement is interposed between the vibrators and the belt.

Title: Cine cameras
IPC: G03B7/085
Filed: 1972-09-25
Abstract: 1396570 Cinematography AGFA-GEVAERT AG 25 Sept 1972 [24 Sept 1971] 44242/72 Heading G2E A cine camera capable of fading-in and fading- cut includes a capacitor which charges on fading- in and discharges on fading-out, or vice-versa and a control device which, only when the film drive is stationary, permits the capacitor to rapidly assume the state of charge corresponding to the commencement of a fade-in. The camera control circuit of Fig. 1 is similar to that described in Specification 1395731 and includes motor control circuit 100, aperture regulator 102, Schmitt trigger 103 and control stage 101. It operates as follows. On closing switch 104 the photo-resistor 128 determines the reading of the galvanometer 126 which in turn sets the camera aperture. Simultaneously the capacitor 135 is charged since the transistor 130 is off. If the dissolve switch 123 is now closed (with the film drive motor 106 switched off) the thyristor tetrode (t.t.) 118 supplies a positive pulse via the diode 119 and motor 106 to switch on transistor 130 abruptly, and to discharge capacitor 135 through the transistor 130. The resulting rapid increase in the galvanometer current causes a reduction in the aperture to produce a rapid fade-out. The switching on of the transistor supplies a pulse via resistor 146 to the trigger 103. This produces a pulse to the base of transistor 111. On closing switch 114, the capacitor 115 discharges to switch on the amplifier defined by transistors 109, 111 so energizing the electromagnet 110 to close contact 108 to power the motor 106. Simultaneously the t.t. 118 closes and the capacitor 135 charges since the transistor 130 is now off. The galvanometer current is reduced and the aperture opens to produce a fadein. To fade-out at the end of a filming sequence switch 123 is again closed the sequence of operations being the same as in Specification 1395731. In control circuit of Fig. 2, there are similar aperture control and motor control circuits and a bi-stable tripping stage 150. To operate, switch 104 is closed. To set the circuit ready for a fadein switch 123 is closed which supplies a pulse to transistor 152. The stage 150 thus pulses the base of transistor 130 opening it and causing a fade-out to rapidly occur. The capacitor 135 is discharged. Closing switch 114 switches on motor 106 and the movement of contact 108, caused in the switching on of the motor 106, short circuits the stage 150. The transistor 130 switches off slowly as capacitor 135 charges and a fade-in is produced. To fade-out while the motor 106 is running the switch 123 is again closed. Since the stage 150 is short circuited the transistor 130 switches on more slowly at a rate determined by the discharge rate of the capacitor 135.

Title: Improved can top
IPC: B65D17/34
Filed: 1965-10-19
Abstract: 1,086,989. Opening cans. E. C. FRAZE. Oct. 19, 1965 [Nov. 2, 1964], No. 44284/65. Heading B8D. A pull tab 15, attached to a tear-out portion 14 of a can end by means of an aperture in the tab surrounding a rivet 18 formed in the portion 14, has slits 24 leading to holes in the tab so that on raising the tab it bends about a line 26 and parts 27 of the tab fulcrum on the can end to start tearing out the portion 14 along the adjacent part of a score line 12 by which the portion 14 is defined. The tab is first raised to a position, Fig. 4 (not shown), at which the camming action by the parts 27 can begin, the stresses created during this secondary lever action then leading to rupture of the score line 12. At this moment, Fig. 6 (not shown), the rivet 18 serves as a guard against escaping gases from the contained liquid. The can top may be of aluminium or steel. The tab, of sheet metal, has a shoulder (30), strengthening rib (33), a raised end portion (34) and bosses (37) on its underside, Fig. 3 (not shown), enabling it to be readily grasped. The can end has a recess (35) permitting access to the tab and providing a means to prevent the can end flipping outwards during filling. Indentations (46) in the can end, Fig. 7 (not shown), below the parts 27 of the tab delay camming contact between the tab and can end.
