Title: Improvements in or relating to photographic printing apparatus
IPC: G03B27/46
Filed: 1939-07-26
Abstract: 530,431. Photo-electric control of photographic exposure. KODAK, Ltd. July 26, 1939, No. 21698. Convention date, July 26, 1938. [Class 40 (iii)] [Also in Groups XX and XVI] A photographic printing apparatus comprises a driven power shaft, mechanism for feeding a negative film strip into position in front of a printing lamp, mechanism for feeding a strip of printing paper or other sensitized material over a rotatable drum positioned in the path of the rays transmitted by an image area on the film strip, a gate member associated with the drums for holding the sensitized material thereagainst during the exposure, means controlled in accordance with the density of said area for adjusting the intensity of the rays, and means for intermittently connecting the film feeding and paper feeding mechanisms to the power shaft. The apparatus shown diagrammatically in Fig. 1 is intended for enlarging from eight-exposurenegative films, which are joined together to form a continuous strip 30 having blank portions at the joins equal in size to the frames. Two frames are projected simultaneously on to printing paper 268, forming images arranged side-by-side on it. Before each exposure photo-electric cells measure the light passing through each frame and adjust a resistance in the circuit of the corresponding projecting lamp the intensity of which is thereby varied to give the correct exposure. The image areas are separately illuminated with different light from lamps 202 conveyed through internally-reflecting blocks 209 with sheets of ground or opal glass 210 at their ends. Before the exposure is made, photo-electric cells 222 arranged out of the path of the direct rays measure the intensity of the light transmitted through each frame and cause contact members 227 to be correspondingly adjusted between spaced fixed and movable resistance elements 225, 226, Figs. 14 and 25. During this period the lamps are fed through pre-adjusted resistances 221. A cam 241 on the shaft 46 then raises a rod 234 carrying a cross-arm 233 which raises members 230 carrying the resistance elements 226, which are thereby moved to clamp the contact members 227 between them and the elements 225. At the same time an arm 247 operates switches 244 which substitute these resistances thus adjusted, for the resistances 221, thereby adjusting the intensity of the lamps in accordance with the density of the images. Pivoted shutter blades 251 are then moved to uncover the lenses 249 for a definite time.

Title: Improvements in or relating to machines suitable for sewing rands to shoes
IPC: D05B15/00
Filed: 1954-07-31
Abstract: 773,895. Welt Butting &c. machines ; sewing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (Deutsche Vereinigte Schuhmaschinen Akt.-Ges.). July 28, 1955 [July 31, 1954], No. 22405/54. Classes 17 (1) and 112. A rand cutting attachment for use in a machine for severing rands to the marginal portions of shoe uppers, has a rand detecting feeler device 37, a knife 3 associated therewith, means to move the device along the marginal portions of the upper into contact with the leading edge of the rand already attached to the shoe, and means to cause the knife to sever the rand in a locality determined by this position of the detecting device. The knife 3 is slidable in a housing 2 which is adjustable on carrier arm 5 pivoted at 15 in bracket 20 pivoted on shaft 1, has on opening 8 through which the rand passes in its approach to the needle, and provides a shearing edge 9 for the knife. The upper face of the rand lies against a pin 10, and springs 14 hold the rand in position for cutting and support the severed end. The feeler device comprises an upper rod 35 with a roll 36, and a lower feeler rod 37 with a turned and bevelled end 38 for engaging the bevelled end of the rand. Rods 35, 37 are adjustable lengthwise in blocks 39, 40 hinged together on a stud 43 on arm 44 secured to arm 5. The feelers are normally held apart, clear of the shoe, by spring 61. In operation the machine is stopped after the rand has been almost completely attached, e.g. as in Fig. 1, and knob 64 is twisted anticlockwise about 90 degrees so that shaft 46 is turned and, by engagement of pin 48 in spiral groove 47, moved lengthwise, and this movement is transmitted through cable B to close the feelers on the work. The knob, held in this position is moved to the right to swing lever 25 and bracket 20 so that the feeler device and severing mechanism move along the shoe margin until the bevelled face of feeler 38 engages the leading end of the rand. This movement of lever 25 is transmitted yieldingly through spring 28 to prevent distortion of the end of the rand, and if desired lever 25 may be moved to and fro, about the pivot provided by balls 21, to ensure that the feeler is engaging the rand. Lever 25 is then swung downwardly about stud 24, and through cable A causes the knife 3 to sever the rand at a point, determined by feeler 38, such that the ends of the rand will abut neatly.
