In an extrusion adapter 10 for preparing multi-layer films or sheets a cylindrical passage 12 is contained in a housing 11. The housing also contains hemi-toroidal plenums 40 and 41, the plenums being separated by dam portions 28 and 38, communicating with polymer sources 45 and 46 respectively, and with the central passage by a passageway 43, and hemi-toroidal plenums 59 and 60 separated by dams 50 and 57 and communicating with polymer sources 63 and 64 and with the central passage by a passageway 61. Two bushings 70 and 75 are located in the central passage and have inlet ends of circular cross-section and outlet ends of elongate cross-section, the bushings being oriented in such a way that their elongated slots are parallel to the slot of the sheeting die. The bushings are disposed such that their discharge ends are situated between the plenum passageways and the discharge end of the central passage. In operation the discharge end 13 of the central passage communicates with a sheeting die (not shown) and a first polymer is supplied to the inlet end 14 of the passage 12. The bushing 75 forms this material into an elongate configuration at its discharge end 77 where second and third polymers from hemi-toroidal plenums 59 and 60 enter through passageway 61 and encapsulate the first material. The composite stream issuing from the second bushing 70 is then encapsulated with polymers from hemitoroidal plenums 40 and 41 entering by passageway 43. The five layer composite film then passes to the sheeting die from where it is extruded.

Title: Improvements in and relating to wage registering and printing apparatus
IPC: G06C27/00
Filed: 1938-09-15
Abstract: 519,182. Registering and printing apparatus. MARSCHIK, C. Sept. 15, 1938, No. 26930. Convention date, Sept. 16, 1937. [Class 106 (i)]  A device for registering and printing wages corresponding to work done on a machine comprises a counter with indicating numerals and type elements, a frame provided with means for holding one or more tickets interleaved with carbon paper and adapted to slide beneath the counter, an impression means operated by the sliding movement of the frame to home position, and mechanism for zeroizing the counter on the reverse movement of the frame. The indicating and type wheels, which form part of or are driven by a wages registering mechanism of a machine (not shown), are mounted on a spindle 19, Fig. 1, in a support 10 formed with guides for a sliding frame 7. The frame 7 supports an auxiliary frame 11 with a hinged flap 13 for the reception of ticket blanks 16 and carbon sheets. Extensions 9 on the frame 7 carry tappets 8 adapted to co-operate with pivoted cams 6 on spring-controlled arms 2 that support an impression bar or hammer 1. When the frame 7 is pushed into the support 10 the tappets 8 stress the springs 4 and then' release the cams 6 to permit the hammer 1 to make an impression on the tickets 16. At the end of this movement one of the tappets 8 operates a bell-crank 24 and a cam 22 thereon, Figs. 3 and 4, moves a sleeve 20 axially of the shaft 19 to engage a pinion 21 with rack teeth 25 on an extension 9 of the frame 7.

Title: Improvements in or relating to electrical gas discharge tube circuits
IPC: H01J21/06
Filed: 1953-10-05
Abstract: 743,237. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and BEESLEY, J. H. Sept. 30, 1954 [Oct. 5, 1953], No. 27240/53. Class 40 (4). A set of gas discharge tubes are arranged in groups, and their outputs are connected to leads in such a way that on a combination of tubes, one from each group, being struck a signal appears on a lead individual to that combination. The arrangement is described with reference to a translator in which coded signals applied one to each of the leads of groups A ... C are converted into a route designating signal on one of leads 45 . . . 53. Thus assuming signals are received on leads 2, 5, 8, these are arranged to strike tubes 10, 18, 21, whose cathodes are connected via rectifiers 61, 64 and resistance 58 respectively to lead 49, whose potential only rises sufficiently when all three of the tubes are struck, to fire a route-designating tube 27. Since the firing of a tube 21 in group C might transmit over lead 49 to the cathodes of tubes in the other groups a sufficient rise in potential to prevent them being struck, it is arranged that no tube in group C may be struck until one tube in each of the other groups is struck. Thus the striking of any tube in group A causes tube 10 to strike and a similar tube 12 is provided for group .B. Only when both of these tubes is struck can tube 11 of group C strike, thereby back-biasing rectifiers 41 . . . 43 to remove a shunt on the input paths 7 ... 9 for the tubes 20 ... 22 so permitting the appropriate one to be struck.
