[Class 130] A continuous-rod filter-tip machine in which a continuous rod of tobacco is compressed before being allowed to expand as it passes through a tube 7. comprises a chamber 13 in a member 9, which is intermittently moved to replace a portion of the tobacco rod by a filter tip in another chamber, and a duct 16 leading to the usual garniture in which the paper wrapping is applied. The machine is similar to that described in Specification 414,087, but binding of the tobacco is prevented. The tobacco, which has been showered on to a tape 2 is compressed by a driven roller 3 and a free roller 4, an intermediary guide-block 6 being provided. The tube 7 gradually increases in bore and carries a perforated plate 8. The member 9 comprises a drum which is intermittently moved about a shaft 10 to bring a series of bores 13 in succession into line with the tube 7. The duct 16 is followed by a tubular part 17 cut away to accommodate the endless belt and the cigarette paper 19 coming over a roller 20 and moving on to the garniture. The bores 13 and the ducts 16, 17 both have greater diameter than the adjacent end of the tube 7. Mouthpiece stubs 154 are fed from a hopper 22 to a chamber 13 by a plunger 50 which is reciprocated by a pin on a disc 44. The drum is moved by a cam on the shaft 34 to sever the tobacco between the plate 8 and the duct 16, and to replace it by a stub in the next chamber, the severed tobacco being ejected later by a further plunger 51 moved simultaneously by a plunger 50, springs 53 preventing damage if jamming occurs. The tobacco carrying tape 2 moves at a faster rate than the paper 19.

Abstract: 657,523. Tape dispensers. SPYK, P. G. J. VAN, and STANDARD ADVERTISING TAPE CO., Ltd. Dec. 6, 1948, Nos. 31650/48 and 12680/49. [Class 18] A holder for a reel of advertising tape 2 for tying up parcels and for a roll of adhesive tape 30 for securing the advertising tape to the parcel comprises a housing 1 having a removable base 3, attached to the housing by lugs 4 and a finger operable spring clip 9. Slotted side panels 24 are bent up from the base 3 and support the reel of advertising tape 2 within the housing. A bracket 27, having slots in each side wall for supporting the roll of adhesive tape 30 is mounted on the top of the housing 1 and is provided with an aperture 33 in its front wall through which the adhesive tape 30 is withdrawn. The advertising tape 2 is withdrawn through a slot 38 in the top of the housing 1 and over a guide 39 which keeps it clear of a cutter 19 mounted on the front wall of the housing. A tensioning device for the advertising tape is provided in the form of a pivoted arm 42 which rests on the tape prior to it passing over the guide 39. A second cutter 32 having an ineffective central portion 32a is secured to the upper end of the front wall of the bracket 27. In operation the two tapes are gripped and withdrawn together from the holder being initially held apart by a separator 45 which comprises a rolled portion 45a secured to a pivoted arm 44 and having lugs which are attached to a second pivoted arm 43 carrying a coiled wire 46 over which the adhesive tape passes, the advertising tape passing below the rolled portion 45a. After sufficient length of adhesive tape has been withdrawn the two tapes are pressed against the cutter 32 which severs the adhesive tape but due to its ineffective central portion fails to sever the advertising tape. The advertising tape is then secured to a parcel by the adhesive tape and is then withdrawn by itself to tie up the parcel. To secure the end of the advertising tape the adhesive tape is again withdrawn with the advertising tape until sufficient tape has been withdrawn whereupon both tapes are severed on the cutter 19. When it is desired to use only the advertising tape, the adhesive tape is retained in an inoperative position by the raising of the separator 45. In so doing, however, the adhesive tape is led behind a looped wire 49 which prevents the advertising tape being inadvertently pressed against the adhesive tape. A hood 47 having an open front portion, encloses the bracket 27 and adhesive roll of tape, the hood being secured to the rear of the housing.

Title: Improvements relating to electric circuit-breakers of the auto-reclosing type
Inventor: GRAY WILLIAM
IPC: H01H75/04
Filed: 1959-09-16
Abstract: 902,245. Automatic circuit-breakers; protective cut-out systems. REYROLLE & CO. Ltd., A. Dec. 16, 1960 [Sept. 16, 1959], No. 31661/59. Class 38 (5). In an auto-reclosing circuit-breaker having a spring closing mechanism charged by a repeatably energized electromagnet in conjunction with a ratchet, the electromagnet winding is embedded in insulation of cast synthetic resin and a contact at which one end of the winding terminates is carried on the surface of the insulation and is repeatedly connected and disconnected from the circuitbreaker supply to effect spring charging. As shown, the main circuit-breaker contacts 10, 12 are tripped under fault conditions and a contact 13 on the supply side contact 12 engages a control bridge 29 to energize through contacts 28, 31, 29A, the winding 25 which is embedded in epoxy resin (preferably that known under the Registered Trade Mark " Araldite "). The armature 16 is attracted to move a rod 20 downward, stressing springs 24, 33 and driving a spring charging shaft 23 through an arm 21 and ratchet 22, the shaft also having a further ratchet (not shown) preventing reverse rotation. Near the end of the armature movement a mechanism, not shown, moves a detent 34 to the left, allowing a rod 32 to be moved downward by the spring 33 opening contacts 28, 29, 30 to de-energize the winding 25. The armature 16 and rod 20 move upward due to the spring 24 and a pin 37 on the rod 20 engages the end of a slot 38 to lift the rod 32 to relatch on the detent 34 and reclose the contacts 28, 29, 30 so as to repeat the charging stroke. When the closing spring is fully charged it is released to close contacts 10, 12 and contact 30 is moved to a position where it cannot be engaged by the contact 29. If the contacts 10, 12 reopen the charging operation is repeated and after a preset number of reclosures a counter (not shown) moves a bolt 40 into the path of an abutment 41 on the rod 32 to prevent reclosure of the contacts 28, 29, 30. Contact 29A is arranged to move with the contact bridge 29. In an alternative arrangement, not shown, the parts 33, 34, 37, 38 are omitted and the rods 20, 32 are coupled by a snap-action spring. The time delay between reclosures is the time required for spring charging.
