Title: Metering/shutter cocking interlock
IPC: G03B17/42
Filed: 1974-04-29
Abstract: 1466939 Advance and shutter mechanism EASTMAN KODAK CO 29 April 1974 [30 April 1973] 18631/74 Heading G2A In a camera for receiving a film having metering perforations and having means for sensing said perforations by entering same, upon which the film advancing mechanism is disabled, this disablement does not take place if the shutter driving means has not been cocked. Fig. 1 shows the mechanism in the cocked position, just prior to the picture-taking operation. The high energy lever 30 is biased clockwise by a spring 34 engaging a lug 35 thereon, and when released, a surface 36 thereof actuates the shutter. The lever 30 is latched in the Fig. 1 position by a lug 26 on a release lever 22. A metering lever 42 is biased clockwise about a pin 44 by a spring 46. In the Fig. 1 position a sensing slide 54 is biased by a spring 58 connecting it to lever 42, and the slide terminates in a pawl 60 which is shown as engaged in a perforation 18 in the film-strip 14. The lower end of lever 42 has a pawl 63 which is shown as engaged with a ratchet wheel 64, preventing rotation of the ratchet and hence the film advance mechanism of the camera. When the release lever 22 is depressed, lug 26 disengages from high energy lever 30, which is accordingly driven clockwise to actuate the shutter, position of Fig. 4. Lug 35 of the lever engages and pivots lever 42 anti-clockwise, so that pawl 63 is disengaged from ratchet 64, and slide 54 is pulled downwards to disengage pawl 60 from the film perforation. At the same time a cam surface on lever 22 causes lever 30 to take a tilted position Fig. 5 (not shown), so that an inner cam surface 38 on lever 30 comes into a position where it is engageable by a lug 62 on lever 42. The film is now advanced by pushing slide 70 to the left. At the same time a lug 74 on the slide engages lug 35 on lever 30 and pivots it towards its cocked position. Lever 42 moves with lever 30, because of spring 46, and slide 54 also moves upward until pawl 60 bears against the underside of film 14. After slide 70 has moved about two thirds of its full travel, lug 35 disengages from lever 42. This is, however, prevented from being driven by spring 46 into locking engagement with ratchet 64 since lug 62 is still engaged with cam surface 38 because of the tilted position of lever 30. As slide 70 reaches the end of its full travel, lever 30 reaches its fully cocked position, and also disengages from the cam surface on lever 22, so that it is no longer tilted. As a perforation 18 becomes aligned with pawl 60, it is entered thereby. Further movement of the film causes the perforation to pivot slide 54, and so allows lever 42 to be pivoted once more into the transportlocking position of Fig. 1.

Abstract: 1,218,866. F.E.T. storage circuits. INTERNATIONAL BUSINESS MACHINES CORP. 24 April, 1968 [25 May, 1967], No. 19305/68. Heading H3T. [Also in Division G4] In a storage circuit having a bi-stable circuit including two cross-coupled insulated gate field effect transistors Q1, Q2, the load of each transistor includes an insulated gate field effect transistor Q3, Q4 and the gate of each transistor Q1, Q2 iS connected to a semi-conductor switching device Q5, Q6, whereby when both the load transistors Q3, Q4 and the switching devices Q5, Q6 are off the gates of the transistors Q1, Q2 are effectively isolated. The power dissipated in the bi-stable storage circuit Q1,Q2 iS reduced by pulse operation of transistors Q3, Q4. The state of the transistors Q1, Q2 is maintained due to the voltage stored across the circuit capacitances C1 C2. If transistors Q1, Q3 and Q4 are ON and transistors Q3 and Q4 turn OFF then transistor Q1 also turns OFF, but on Q3 and Q4 turning ON again the voltage stored across C2 turns ON Q1 so that the state of the circuit is maintained. In formation may be read out of the store by applying a negative word pulse at 16 which turns ON transistors Q5, Q6-and allows the output at A and B to be fed via 12, 14 to a differential amplifier, the resultant output of which indicates the state of the store. Information may be written in by applying a negative word pulse at 16 and a positive pulse at 12 or 14. The transistors Q1-Q6 may be MOS. In an alternative circuit (Fig. 5, not shown), the gates of transistors Q3 and Q4 may be controlled from separate associative search sources and their drains may be connected to an associative sense line so that the condition of store can be determined by signals applied to the gates of these transistors Q3, Q4. The storage circuits may be connected to form a memory array (Fig. 4, not shown). The write, read and power lines may be transmission lines coupled to the storage circuits by directional coupling techniques. Each row has a common word line and each column has a common sense amplifier connected to the inputs 12, 14. The memory can be powered row by row at different times.

Abstract: 596,538. Bearings. CRAWFORD, T. A., WAITE, J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 30, 1945, No. 19424. [Class 12 (i)] [Also in Group XXVI] Two relatively moving members in bearing contact and exposed to contact by liquid have one of such members provided with a bearing surface formed by a sleeve of silicon iron rigidly held to such member and under compressive stress. The silicon iron should contain at least 8 per cent. of silicon preferably a minimum of 13 per cent. but more preferably contains 14“ to 15 per cent. Thus, as shown in Fig. 1, a centrifugal pump for handling sulphuric acid has its impeller shaft 1 provided with a silicon-iron sleeve 3 forming the journal surface which is supported solely by the packing material 9 of the gland through which the shaft passes. If a simple fixed bearing surface is used it is made of a metal softer than the silicon iron. The silicon-iron sleeve is firmly held on the stainless or mild steel shaft by a stainless or mild steel muff piece 8 shrunk over the sleeve end where it butts against a stainless or mild steel ring 6 engaging against a shoulder on the shaft 1. The sleeve end and ring may be of reduced diameter to allow the muff to lie flush. The shaft 1 screws into a boss on the impeller 2 whereby.the silicon-iron sleeve 3 is put under compressive stress; a thin layer of corrosion resistant material (artificial resin) may be interposed at 4. The packing 9 is of chlorinated rubber and blue asbestos known under the trade name " Clorsul" and is compressed by a gland ring 22 the latter being formed with a lubricant space 25 which is open to the surface of the silicon-iron sleeve 3. In the centrifugal pump shown in Fig. 2 the impeller 20 is keyed to the shaft and a cast-iron or a ductile metal (phosphor bronze) sleeve 13 on the shaft also engages the key such cast-iron or ductile metal sleeve being reduced in diameter for the outer part of its length to receive the silicon-iron sleeve 16 which is held thereon and under compression by a counter-sunk nut 17 screwed on the outer end 19 of the shaft. The silicon-iron sleeve co-operates with packing 18 of material known under the trade name " Clornite " if nitric acid is being pumped. A grease lubricator 29 supplies a space between rings of such packing. The invention is applicable to reciprocating rods, to valve spindles, to stirrers. Lead packing may be used.

Abstract: 1,056,614. Gas dryer; disiccant composition. GENERAL-ERIE CORP. May 11, 1964, No. 19582/64. Heading B1L. Shell 1 containing a desiccant composition has a cooling jacket 40 at its lower end through which water is circulated. Air enters at 50 and after passing through the pipe 52 coiled around the base of shell 1, enters the dryer through pipe 54 which is positioned to discharge the air against the desiccant solution passing through hole 21 in the lower end of cylinder 17. Thus the desiccant solution is atomized and the air thoroughly contacted with the solution. The air then rises through holes in the sides of cylinder 17, through the opening in horizontal partition 7 and passes into contact with the desiccant composition after passage through a foraminous diffuser 10. The dry air passes through pipe 32 and leaves by outlet 30. The upper portion of the shell 1 which is not filled with desiccant acts as a storage space for dry air. Desiccant material may be added through shaft 34. In another embodiment (Fig. 1, not shown) the cooling jacket 40 may be omitted. A further modification may be effected by the omission of cylinder 17. A preferred desicant composition for use in the apparatus comprises 100 parts pelleted urea, 5 parts or less anhydrous flaked calcium chloride, and ¢ part or less of a corrosion inhibitor consisting of sodium borate 96% and sodium nitrite 4%. This desiccant composition may be made by adding an aqueous solution of calcium chloride to pelleted urea whilst it is rotated in a drum mixer. The inhibitor is then added to the mixer.
