Abstract: 1322343 Electro-photographic printer EASTMAN KODAK CO 19 June 1970 [19 June 1969] 29887/70 Heading G2H In an electro-photographic machine the photosensitive material is a three layered web having keyhole apertures at each end so that when threaded through the machine it forms an endless band. This endless band is photo-exposed with an original image through apparatus 3 and is developed by apparatus 4. At the image transfer station a shut-feed roller 8 directs copy sheets into contact with the developed image on the band and each sheet is subjected to corona discharge by a device 5 and heat fixing by a device 7 before delivering to a tray 9. The band passes round a tensioning roller 48 before being cleaned by apparatus 6 which is bodily movable towards and away from the band. Charging is effected by a device 2 before re-imaging by the apparatus 3. When the band needs renewal the tensioning roller 43 is slackened and the band drive is reversed. An empty cassette 20 is placed in a box 10 adjacent the band and rollers 80 and 81 are dropped into position to contact the band the speed of the roller 80 being greater linearly than the band. The cleaning apparatus 6 is removed from the band surface and these operations are carried out automatically in dependence on an electrical control circuit. The contacting roller 80 disconnects the band at each end from fixing means 40 in the machine and causes it to be wound as a web into the cassette 20. A new web is fed to the machine from the box 10 being removed from a cassette therein by the rollers 80 and 81 after automatically typing through the leading keyhole apertures to a tie bar 40 carrying studs which is caused to move around the machine in the operative path of the endless band. The tie bar 40 carries studs to connect both ends of the web and from the band.

Abstract: 429,471. Wireless receiving systems. JOHNSON LABORATORIES, Inc., 609, West Lake Street, Chicago, U.S.A.-(Assignees of Polydoroff, W. J. ; 420, Fullerton Parkway, Chicago, U.S.A.) April 6, 1934, No. 30002. Convention date, April 22, 1933. Divided application. [Class 40 (v)] In a wireless receiver tuned by ganged variable inductances of the moving core type, the tuning range is altered by varying the capacity of the tuned circuits by switching in fixed condensers. In a modification, the tuning ranges may overlap, each frequency in the overlapping region corresponding to two settings of the moving cores and each setting corresponding to a different degree of selectivity. The tuning inductances 1, 1<a>, 1<b>, 1<c>, are associated with condensers 5, 5<a>, 5<b>, 5<c> respectively. On operating the wave band switches 15, condenser 6 is substituted for condenser 5 ; condenser 5 is put in parallel with condenser 4 to modify the aerial coupling ; condensers 6<a>, 6b, 6<c> are put in parallel with condensers 5<a>, 5<b>, 5<c> respectively ; and condenser 9 is put in parallel with condenser 8 to modify the coupling between valves 7, 7<a>. When the tuning ranges overlap, the ratio of inductance to high frequency resistance will be different over each range, giving different degrees of selectivity. In this case, each tuned circuit may comprise two separate inductances, each designed to cover separated ranges with or without additional capacities, each coil being adapted to cover two overlapping ranges. Each such pair of coils may co-operate with a single core transversely movable to engage either coil, Fig. 5, (not shown). The condensers 5, 6, 5<a>, 6a, &c., are enclosed with their associated coil in a shield. Specifications 366,475; 403,368, 403,426, and 405,623, [all in Group XXXVI], are referred to. According to the Specification as open to inspection under Sect. 91, the coils may be replaceable by a second set of coils designed to cover a different frequency range. This subject-matter does not appear in the Specification as accepted.
