Title: Rivetting apparatus
IPC: B21J15/10
Filed: 1973-11-26
Abstract: 1453087 Riveting C E BREWER 26 Nov 1974 [26 Nov 1973] 54822/73 Heading B3U A riveting apparatus comprises at least one rivet engaging assembly 3 displaceable from a tubular rivet receiving station A to a riveting station C and having at least one member 21<SP>1</SP>, Fig. 3, which is displaceable into a rivet engaging position during its travel from station C to station A and which is removable from the rivet at the riveting station C before substantial deformation of the rivet has occurred. In one embodiment, four or more assemblies 3 are mounted on a rotor 1. Each assembly 3 comprises an anvil 20<SP>1</SP> urged radially outwardly by springs (51<SP>1</SP>) (Fig. 4, not shown) and rivet engaging pins 21<SP>1</SP> urged outwardly by springs 29<SP>1</SP> mounted in a slide block 22<SP>1</SP> which is releasably connected to a cam follower 23<SP>1</SP> via a spring biased pin 35<SP>1</SP> engaging rollers on the follower 23<SP>1</SP>. When a hammer 9 is lowered by a ram 5 to effect riveting at the station C, the anvil 20<SP>1</SP> and slide block 22<SP>1</SP> are forced inwards by the hammer 9 causing the slide block 22<SP>1</SP> to disengage the cam follower 23<SP>1</SP> and to drop on to a block 43<SP>1</SP> so as to withdraw the pins 211 from the rivets. During the return stroke of the hammer 9, the rotor is rotated through 90 degrees by a rack 6, connected to the hammer 9, and pawl 16. During rotation of the rotor, the cam follower 23<SP>1</SP> is pressed downwardly against spring bias 41<SP>1</SP> by a cam surface 10<SP>1</SP> so as to re-engage the slide block 22<SP>1</SP>. At station A, the cam surface 10<SP>1</SP> is discontinued so that the cam follower 23<SP>1</SP> is moved upwardly by the spring 41<SP>1</SP> taking the slide block 22 with it, thereby causing the pins 21<SP>1</SP> to engage the bores of rivets waiting at station A. During descent of the rack 6, the rotor is prevented from rotating by a spring loaded stop 18. In another embodiment, the anvils 20<SP>1</SP> are rigidly attached to the rotor and each slide block 22<SP>1</SP> is lowered at station C by a member 60, Fig. 2, which is pushed into a recess 56 in the block 22<SP>1</SP> by a cam 176 when the hammer 9 is lowered. During travel from station A to C, the rivets are prevented from disengaging the pins 21<SP>1</SP> by an arcuate guide or by the exhaust gas from the ram 5. More than one rotor may be provided.

Abstract: 1,160,479. Rolling. SCHLOEMANN A.G. 4 Dec., 1967 [7 Dec., 1966], No. 55071/67. Heading B3M. [Also in Division F2] A rolling mill coupling, for releasably connecting an articulated driving spindle 15 and a roll journal 1, includes link box 2 which has cavities at opposite ends for receiving the spindle and journal, and which carries pawls 5 pivoted to a fixed plate 7. The pawls are spring urged outwardly so that noses 5<SP>1</SP> of the pawls are received in a transverse, undercut, groove 3 in the journal 1 to retain the journal within the link box. The pawls are releasable from the groove by pins 11 which are movable radially inwardly, by means of pressure pistons (not shown) carried by members displaceably arranged on the mill housing. The release of the link box from the splined or flattened roll journal is relatively simple and quick, in order to facilitate rapid roll changing in the mill.

Filed: 1971-12-01
Abstract: 1330963 Film cartridge BELL & HOWELL CO 1 Dec 1971 [14 Dec 1970 16 July 1971] 55683/71 Heading G2E A film cartridge has a housing apart 11 which provides space for a roll of film 44 and a second part 10 able to accommodate an audio tape cassette 13, and film drive sprocket wheels 39, 40. Film guiding surfaces 14, 18, 20, 21 can support the film 44 and direct it towards member 31 which is urged by spring 35 towards the wall 36. The member 31 urges film 44 being would into the cartridge to form a wound mass. When a film 44 has been almost wound back into the cartridge and the sprocket wheels 39, 40 engage only two film perforations the spring urged member 31 resists the further take-up of film on to the wound mass so causing the film 44 to move from the piston shown in continuous lines to that shown by dotted lines in Fig. 3. Thus when removal of the film 44 from the cartridge is required clockwise rotation (as viewed) of the sprocket wheels 39, 40 will readily withdraw the film, the need to engage the leading end of the film 44 being avoided.

A method of testing coins and selecting those coins of a predetermined denomination irrespective of whether the coins contain magnetic or non-magnetic material comprises passing an alternating magnetic field through the coin to be tested, detecting the variation in field strength due to the coin and applying the detected signal to discriminating means so that coins causing a variation within predetermined limits are accepted and all others rejected, the frequency of the magnetic field being chosen so that the variation in field strength will be substantially the same for both types of coin of said predetermined denomination. The coin 19 passes between an energizing circuit 22 generating an alternating magnetic field and a detection winding 25. An additional winding 27 encircling the coin may be connected in series with the detection winding. The alternating voltage induced in the winding 25 is rectified and applied to peak detectors 30, 31. If the value of the induced voltage lies between the limits set by peak detectors 30, 31 logic circuit 32 is operated to energize relay 34 controlling a deflector in the path of the coin.

The removal may be by brushes (3, 3') rotated by a motor (4) as illustrated in the Fig. (not shown). Alternatively, the removal may be by ultrasonic vibrations, jets of liquid under pressure or by vigorous stirring of the electrolyte. Porous Ag powder can be produced having particle sizes of 300 to 1500 Angstroms. the complexed Ag cations may be derived from silver nitrate, sulphate, acetate, halide, oxalate or ammoniacal silver hydroxides. A colloid such as carboxymethylcellulose may be added to the electrolyte to prevent agglomeration of the powder. The electrolyte may be circulated through a heat exchanger (6) by a peristaltic pump (5). Specified electrolyzing conditions are a temperature of 10-50‹C, a current density of 2-50 ma/cm<SP>2</SP> , an aqueous electrolyte made up from AgNO 3 , Na 2 B 4 O 7 NaOH, NH 4 OH and carboxymethylcellulose.

Abstract: 598,441. Combined printing and embossing apparatus. ROYAL LACE PAPER WORKS. Sept. 4, 1945, No. 22706. Convention date, Nov. 25, 1944. [Class 100 (ii)] Ornamental articles such as shelf edgings are produced by a combined transfer printing and embossing process upon a layer of plastic material 1 such as a thermoplastic or thermosetting artificial resin or cellulose material. A transfer web 7 which may be formed of or coated with polystyrene is printed by rolls P, P<1> with an ink comprising an alcohol or water soluble dye dissolved in a resin such as polyvinyl acetate, and the web 7 transfers a printed impression to a layer 1 of cellulose acetate as it is conveyed by a belt 9 from an extruder 8. The layer 1 may be of cellulose acetate butyrate, polyvinyl acetate, polyvinyl acetate chloride, nylon, or vinylidene resin, and the printing medium is adapted to the plastic. An embossing roller E acts upon the belt 7 at places corresponding to the whole or part of the printed impression, so as to give a bas relief effect to the whole or part of the design, e.g., the bloom of a rose of which the stem and leaves are not embossed. The bas relief is seen when viewed from the unprinted side of the transparent plastic. The plastic layer may be finished by applying a coat of varnish. The invention may be carried out by flat printing and embosssing processes, and variations may be made in the nature of the printing ink and the transfer surface 7.
