Title: Improvements in a double exposure preventative for cameras
IPC: G03B19/04
Filed: 1928-09-21
Abstract: 297,440. I. G. Farbenindustrie Akt.- Ges., (Assignees of Slocum, B. A.). Sept. 21, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Magazine hand cameras for roll films, with connected action between shutter and changing-mechanism.- The shutter operating- lever of the camera, is prevented from returning to its original position after making an exposure by a hook which is moved from its obstructing position only when the film is wound. The device may be associated with a exposure counter actuated by the shutter operating-lever. As shown, the shubter operating-lever 5, Fig. 1, is connected by a link 25 to a lever 27 fast with a shaft carrying a counter disc 21 and a toothed wheel 20 engaged by a spring-urged driving and retaining pawls 28, 41, mounted respectively on the pivot 26 of the link 25, and on a fixed pivot. 40. A resilient arm 31 fixed at one end 30 carries a hook 33, and is connected at its free end 39 by a cable 38, Fig. 4, to a bell-crank lever 34 the arm 36 of which lies in the path of a claw 11 adapted to feed the perforated sensitive film 13 in known manner when the slide 7 carrying the claw is' displaced by operating an external knob 8. Before exposure, the hook 33 is pressed by the arm 31 against the rear face of the link 25. On depressing thet lever 5 to make an exposure, the link 25 moves downwardly and laterally, the pawl 28 turns the counter disc 21, and the hook 33 slips off and engages the edge of the link 25 so that, when the lever 5 is released, the link 25 and therefore the lever 5 cannot return to their original positions until the winding of a fresh length of the film. acting through the gearing 11, 34, 38, displaces the hook 33 out of the return path of the link 25. If the camera has no exposure, counter, the hook 33 mav co-operate with an extension provided on the lever 5. The device functions when the shutter is set for time exposures owing to the fact that the partial return of the lever 5 after the first downward stroke is permitted.

Title: Hole digging apparatus
IPC: E21B11/04
Filed: 1949-10-24
Abstract: 658,232. Borehole apparatus. WITHERS, J. S. (Darin & Armstrong, Inc.). Oct. 24, 1949, No. 27250. [Class 85] Apparatus for boring in the earth vertical holes 115 with enlarged bottoms 116 for concrete columns comprises a bucket 20 having formed in the bottom a hinged cutting door or doors 24 that dig away the bottom of the hole and guide earth into the bucket as it rotates. To enlarge the cross section of the hole at any particular level, hinged cutting portions 26 forming parts of the bucket sides are swung outwardly about axes upwardly inclined away from the direction of rotation of the bucket. The bucket is rotated by a shaft 22 of square cross section slidably engaging in an orifice of similar cross section formed in the bracing struts 90 of the bucket, the shaft being rotated by a rotary table structure 81 secured to the crane boom 13. Separate cables support the shaft and the bucket, and for boring a shaft of regular cross section relative movement between the bucket and the shaft is prevented by a pin 92 passing through them, the bucket and shaft supporting cables being paid in or out at the same rate as the assembly is lowered into or withdrawn from the hole. To open the doors for dumping, either the bucket supporting cable is paid out, or the other cable wound in. The side cutters are connected to a plate 132 by pivoted arms 170 and are moved to and from a digging position when the plate is rotated. The rotation is caused by relative movement between the shaft and the bucket, the pin 92 having been withdrawn. To the shaft are connected two ropes 145, 160 which, having passed over suitable pulleys are wound in opposite directions around the periphery of a disc 140 secured by a tube 135 to the plate so that, as the shaft moves relative to the bucket into or out of the sleeve, one cable is paid off and the other cable is paid onto the disc resulting in a rotation of the disc, sleeve and plate, and movement of the side cutters. In a modified form, the side cutters are moved as the shaft moves relative to the bucket by a system of levers, there being no rotating parts.

Title: Improvements in tanning machines
IPC: C14B1/00
Filed: 1945-10-18
Abstract: 625,653. Tanning- machines. WILKS, G. L. Oct. 18, 1945, No. 27444. [Class 76] The tanning of hides is expedited by drawing each hide 1 through a pit containing the tanning liquor and over a roller or equivalent member 3 in order to flex the hide progressively from top to bottom ; the movement of the hides through the pit and over the roller is then reversed so as to flex the hides in the opposite direction. The hides are carried by clips 36 on poles 2 stretching across the pit, and pick-up devices 14 mounted on a chain 4, engage with pins 15 and move the poles one at a time through the pit. The pick-up devices are formed with spring- urged arms 16 which are lifted clear of the pins 15 when the rollers 19 travel over the poles. Fig. 8 shows a device disengaging. When all the hides have been transferred, the chain 4 is reversed, a spring-urged pawl 23 altering the position of the pick-up devices. The roller 3 is attached to a second chain 9 and is moved slowly in a direction opposite to that of the hides ; the last pole carries a pin 31 by means of which the roller is detached from the chain and transferred to the other end of the pit. In a modification, Fig. 20, the pit is traversed by a carriage 39 which carries endless chains 43 provided with the pick-up members, so that the hide may be drawn slowly over the roller 3 carried by the carriage, whilst the latter traverses the pit. The carriage carries motors driving the chain sprockets 42, and flanged wheels 40 running on rails 41. A chaintensioning idler pulley 44 is shown. The carriage is provided with two pivoted stop members 53 for the poles which members are lifted out of engagement through link-work 56, 57 when the pick-up members engage depending trip levers. Brackets 61 on the carriage support guide channels 60 for blocks 62 bearing the roller-carrying arms 24, and provision is made whereby pins 31 on the endmost poles disengage dog-clutches to transport the roller assembly from one end of the guide channels 60 to the other. Ramps 59 attached to arms 61 permit movement of the poles over the roller mechanism.

Title: Fully checked electronic printing system
IPC: G06K15/07
Filed: 1965-06-30
Abstract: 1,056,906. Electronic printer control. ANELEX CORPORATION. June 30, 1965 [Sept. 1. 1964], No. 27629/65. Heading G4H. A line printer control circuit includes means for detecting incorrect operation of the print hammers and for detecting when printing of a stored character has been omitted. A line of coded characters is stored in a core matrix (14), Fig. 3a (not shown), and as a character on the continuously rotating type drum enters the printing position, a photo-electric shaft encoder (9) produces the corresponding coded character for successive comparison at (18) with all the characters stored in matrix (14). When code agreement is detected the appropriate print hammers arc actuated by means of distributer gates (39), Fig. 3b (not shown), and gates (25) are inhibited to prevent re-entry of the character in matrix (14). The process is repeated for succeeding characters on the type drum so that, when all characters in the line have been printed, matrix (14) is empty. The delayed print-actuating pulses and the code agreement pulses are supplied to OR gate (OR3), Fig. 3b, which, if a print hammer is correctly operated, produces two successive pulses to set and reset bi-stable circuit (FF5). If a hammer fails to operate, following an agreement pulse or operates when no agreement pulse has been produced, an alarm signal is produced by AND gate (A6): In the character cycle following printing of the last character remaining in matrix (14) OR gate (OR2), Fig. 3b, does not produce an output to set (FF2) and at the end of this character cycle AND gate (A4) produces a " print complete " signal which may be used to initiate printing of the next line, i.e. the line cycle may be terminated before the print drum has completed one revolution from the start of the cycle. If (OR2) is still producing an output after the type drum has performed one revolution (timed by timer (31)) a further alarm signal is developed by AND gate (A5) signifying that not all characters in the line have been printed. This alarm may be used to cause printing of a special character signifying an illegitimate character in matrix (14).

Abstract: 1,137,768. Finishing yarns. GLANZSTOFF A.G. 21 June, 1966 [23 June, 1965], No. 27640/66. Headings D1F and D1W. A multifilment, nylon yarn (which may have been compressively crimped) has uniform, regularly occurring constrictions formed along the length thereof by imposing a compulsory oscillation on the travelling yarn between two fixed points, defined by thread guides, under the action of a gas stream flowing perpendicularly to the direction of travel of the yarn and through which stream the yarn travels twice in each oscillation period. The yarn is fed to the zone between the guides at a speed 5-50%. higher than withdrawal therefrom. In the blowing device shown, a compressed air supply pipe 11 terminates in a "mouthpiece" 13 having a nozzle 12 facing a resonance plate 14. A sleeve 15 comprises slots 16 constituting the thread guides and bores 18 which prevent any back pressure of air in the space between plate 14 and nozzle 12 thereby, making possible the yarn oscillation.

Abstract: 1393385 Photo-electric spectrometers FLORIDA BOARD OF REGENTS STATE OF 13 June 1972 27694/72 Heading G1A In a photo-electric spectrometer, the entrance slit 13 of the mono-chromator 14 is arranged to be oscillated at constant frequency so as to modulate the wavelength of the input beam sinusoidally. As shown, light from source 11 and mirror 12 is passed through the oscillating slit, constructional details of which are as shown in Fig. 2, with apertured plate 35 being carried by rod 42 which is driven back and forth by elongated magnet 43 moving inside solenoids 44, 45 against the pressure of leaf-springs 39. The circuit for the slit drive is illustrated in Fig. 3 (not shown). The grating mono-chromator 14 output passes through test cell 16, in which e.g. polluted gases may be contained, to a photo-multiplier 18. The detector output is amplified at 22 and the D.C. component applied direct to recorder 21, while the A.C. component is filtered at 25, amplified at 26, and detected by chopper/rectifier 27 operating at the second harmonic of the slit frequency. The filtered signal is applied to recorder 21 where it is divided by the D.C. signal to obtain an indication free of source intensity variations. By tuning the amplifier 26 to the slit oscillation fundamental frequency, a first derivative result is obtained; if the second harmonic is used, a second derivative spectrum is obtained.
