Title: Apparatus for pressing together the plastic and fabric layers of a laminated article of footwear
IPC: A43D25/07
Filed: 1949-06-10
Abstract: 658,582. Pneumatic presses. UNITED STATES RUBBER CO. June 10, 1949, No. 15495. Convention date, Aug. 18, 1948. [Class 122(iii)] [Also in Groups V and VIII] A laminated article of footwear 17, the laminations of which comprise plastic and fabric layers, is pressed between two thin elastic diaphragms 11 and 14 by atmospheric'pressure, the space between the diaphragms (which form a closed envelope) being evacuated of air through a pipe 20 secured to diaphragm 11. Diaphragm 11 is secured in a rectangular frame 12 which rests upon the machine frame-work 13. Diaphragm 14 is secured in a rectangular frame 15 which is pivoted at 16 to 13 and is raised to the open position shown by a pneumatic piston rod 23 acting through arm 27, shaft 28 and side arms 29 carrying rollers 30 which bear against brackets 31 on frame 15. Diaphragm 14 descends from the position shown by gravity. The position shown is the rest position of the machine and from that position one cycle of operations is initiated by the operator; the machine runs through the cycle and stops in the position shown. Thus, with the lasted footwear resting on diaphragm 11, the operator grasps two valve handles 51, 52 one with each hand (this is a safety provision) to open valves 53, 54 and admit air pressure from valve 37 to cylinder 24, whereupon rod 23 and diaphragm 14 descend to complete the envelope around the footwear. Just before the end of the downward stroke of rod 23, an adjustable pin 61 on arm 62 secured to shaft 28 makes contact with plunger 60 to open a valve 59 to connect a vacuum pipe line 58 with pipe 20 to exhaust air from the envelope. This closed position persists until air pressure is built up to reverse valve 37, whereupon the parts return to the position shown. A shield 75, for the operator's arm is secured to arm 29 on each side of the machine. The diaphragm 14 is secured in a sub-frame 77 which is fastened to the main frame 78. Fig. 7 shows how the air pressure is built up. Valve 37 comprises a casing 39 housing a piston-type valve 38 which is shown in its rest position. In this position air pressure passes from pipe 40 through port 41 and pipe 32 to hold piston rod 23 up. When the operator opens valves 53 and 54, pressure from 40 through 56, 57 moves valve 38 to the left, to the dotted line position, in which air pressure passes from 40 through port 41 and pipe 33 to depress rod 23. Pipes 43, 43<SP>1</SP> are exhausts. When pressure stands in 33 (during the footwear-pressing operation) it leaks through throttle valve 67, pipe 66, chamber 68 and presently depresses a valve 72 to open it, thus allowing pressure from 40 through 40a and 40b to restore valve 38 to the position shown.

Abstract: 882,978. Photo-conductive devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 16, 1958 [May 16, 1957], No. 15601/57. Class 37. An image intensifier comprises a photo-conductive layer A and an insulating layer C sandwiched between two transparent conductive layers B and D together with apparatus for applying a potential to the conducting layer and for producing a signal voltage across a load resistor R which may be amplified and used to produce an image, for example on the screen of a cathode-ray tube when the photo-conductive layer is scanned according to a raster. Charges are built up in the layer C in accordance with the intensity of the radiation from the image falling on A. When the irradiating image is removed, the potential source across B, D is removed or reversed and the layer A is scanned with a radiation beam thus freeing the charges built up in C. In an alternative embodiment the layers A and C are replaced by two photoconductive layers separated by a thin, opaque, packed mosaic of evaporated metal material so that it is conductive in a direction normal its surface but insulating in a direction parallel to its surface. One photo-conductive layer is intended to be irradiated by the image and the other by the scanning beam. In this embodiment there is no need to remove the irradiating image or to reverse the polarizing voltage in order to read the signal out. Suitable photoconductive materials are amorphous selenium, antimony trisulphide or lead oxide.
