Title: Photographic projection printing apparatus
Inventor: HEIN HENRY FRANK
IPC: G03B21/11
Filed: 1968-09-06
Abstract: 1,245,837. Projection printing apparatus. EASTMAN KODAK CO. Sept. 6, 1968 [Sept.6, 1967], No.42633/68. Headings G2A and G2C. A photographic projection printing apparatus having a magnifiying lens 27 and mirror 28 for projecting microfilm images 21 on to a viewing screen 24 or on to a print exposure station 31, is provided with means for enabling the apparatus to make consecutively two prints of the same microfilm image and with superimposing mechanism which cause supplemental information from a film 40 to be projected on to the station 31 while the first print is being made but not while the second print is being made. The projected supplemental information will obscure part of the projected microfilm image on the finished print. In exposing light-sensitive material 33, a mirror 36 is pivoted from the position shown to a position in front of the screen 24, Fig. 5 (not shown). The apparatus may be used to take only one, unobscured, print of each microfilm image. After insertion of the microfilm in a cassette, a button is depressed to cause lamp 26 to illuminate an image for projection on to the screen 24. Depression of a further button (20a), Fig. 1 (not shown) causes the mirror 36 to pivot to its exposure position. When it is desired that two prints be taken of each microfilm image copied, a switch is closed either manually or (in the embodiment described) by a tab (47), Fig. 2 (not shown) of the microfilm cassette. This ensures that depression of the button (20a) to start a printing cycle will in this case cause the film 40 to be swung into position for projection on to the station 31 by a lamp 38 Fig. 6 (not shown). After the first composite print is made, the film 40 is returned to the position shown and a second print made.

Title: Improvements relating to self-locking nuts
Inventor: BROWNE HAROLD DOUGLAS
IPC: F16B39/284
Filed: 1960-12-20
Abstract: 922,333. Making nuts; forging. SIMMONDS AEROCESSORIES Ltd. Dec. 18, 1961 [Dec. 20, 1960], No. 43744/60. Classes 83 (2) and 83 (4). [Also in Group XXV] The blank, Figs. 2, 4, of a lock-nut (see Group XXV) ready for tapping and with a frusto-conical crown 3 with tapered flutes 8, is produced by cold forging a length of round rod (or by machining the end of hexagon rod, severing the end and then cold forging); the bore 6 is then tapped and a portion 9, Fig. 7, adjacent an edge of each flute 8 is pressed in towards the nut axis by means of a punch with a frusto-conical end recess which either has surface projections, Figs. 8, 9 (not shown), corresponding to the portions 9 and for coaction with a plain crown or has a plain recess for coaction with a crown which has lands 10 on its external surface as shown. Pressing-in of the lands 10 causes the formation of the locking projections 9 of the nut. There may be a final heat treatment. To make it immaterial which nut flat is chosen for orientation of the punch tool, there may be a flute opposite each flat of a landless nut although the edges of three of the flutes will remain undeformed. Cold forging of the round rod with punches and dies produces the hexagon, crown 3 and lands 10. The blank is then pierced to remove the central portion. The pierced slug is retained in the nut body by a spring-loaded devise until a punch removes the pierced slug and produces the three flutes 8, the dispersed material being absorbed. Stripper mechanism removes the blank from the punch. The hexagon bar is first drilled and an oversize frusto-conical crown machined at the end. The blank is then countersunk and severed and the other end countersunk. A cone-like punch is used to produce the lands 10 by cold swaging and the flutes 8 are produced by a formed punch before the bore is re-pierced for clean up.

Abstract: 932,113. Ratchet gearing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 30, 1960 [Dec. 30, 1959], No. 44707/60. Class 80 (3). In reversible ratchet gearing, particularly for selectively advancing or oscillating a punch card feed roll shaft 29, a pair of spring-loaded pawl lifters 34a, 34b are oscillated about pivots 35a, 35b by a cam 13a on a continuously rotating input shaft 12 and act on the ends of spring pawl members 26a, 26b engaging U- shaped notches in wheels 28a, 28b fixed to the output shaft 29, the spring pawls 26a, 26b being fixed to spring-loaded arms 14a, 14b which may selectively be held stationary by solenoids 41, 42 or be oscillated about pivots 16a, 16b by a common cam on the input shaft 12. The arms 14a, 14b are normally held stationary by continuously energized " hold " coils 41a, 42a but are released when opposing or " buck " coils 41b, 42b ate energized. Normally, therefore, as the shaft 12 rotates the pawls 26a, 26b are lifted in and out of the same wheel notches and shaft 29 is stationary. When, however, the coil 41b is energized or " pulsed " to release the arm 14a the pawl 26a is moved bodily in synchronism with its lifting movements and thus engages successive wheel notches to step the shaft 29 forwardly, the pawl 26b on stationary arm 14b being at the same time actuated by its lifter 34a to lock the shaft 29 between its forward steps. Similarly when arm 14b is released the shaft 29 is stepped rearwardly. If both arms 14a, 14b are released the shaft 29 is oscillated so that a punch card 11 is oscillated between adjacent columns. It is stated that the pawl mechanism may be used for moving a notched bar, instead of the notched wheels shown.
