A microimage display system uses a stack of films in spaced parallel planes, the films each having similarly arranged arrays of individual microimages which have been reduced by up to 200 times, as in Specification 942, 639, correspondingly positioned microimages being superposed, the stack being orthogonally adjustable in holder 14 to position a selected superposed set of microimages for projection on to screen 16, and microscope projection objective 17 being adjustable to focus on anyone of the microimages in the selected set for projection. Superposed films spaced by perhaps 375 microns are placed between glass plates 31, 32 in holder 14, the lower plate 32 carrying indexing indicia for each microimage position which may be projected on to a separate screen 60 using beam splitter 64 and mirror 62. Cam 18 is operated by lever 22 to focus spring- loaded objective 17 on either film, screen 60 being correspondingly adjusted by linkage 65. For simultaneous display of superposed microimages, screen 60 is replaced by a further screen 16 which is adjusted to allow for the separation of the two films, a further projection lens 23 being inserted between beam splitter 64 and mirror 62.

Title: Method for the recovery of nuclear fuel from nuclear fuel or breeder elements
IPC: G21C19/38
Filed: 1967-11-30
Abstract: 1,202,074. Processing spent nuclear fuel. KERNFORSCHUNGSANLAGE JULICH G.m.b.H. 30 Nov., 1967 [12 Dec., 1966], No. 54536/67. Heading G6R. Nuclear fuel is recovered from fuel elements or fuel particles which are canned or coated with metal, graphite, or carbides by treating the elements or particles with a molten metal to dissolve the canning or coating and then separating the fuel from the molten bath. Commercial iron, pig iron, or steel serap may be used as the metallic material. If the fuel is in metal or carbide form, the bath is treated with an oxidizing agent, such as iron oxide, air, oxygen, Co 2 , or steam to produce a slag containing the fuel in oxide form. When a large amount of carbon has dissolved in the molten metal, it may be removed by combustion. Reference is made also to the use of tin as the metallic material.

Title: A Device for Moving the Stators of Electric Machines into Various Winding Positions During Winding
Inventor: KUNZEL GOTTFRIED
IPC: H02K15/085
Filed: 1966-12-08
Abstract: 1,162,105. Winding stators. ELEKTROMAT VEB. 8 Dec., 1966, No. 54903/66. Headings B3A and B3E. A device for a stator winding machine for moving a stator to various winding positions during winding comprises rotatable take-up means 1 for the stator, a rotatable ring 2 coaxially mounted therewith, the means 1 and the ring 2 being secured to one another by resilient means 8, the take-up means 1 co-operating with a stop 12 so that when it is locked thereby, the resilient means 8 is stressed, the take-up means being pivoted to the next winding position by the means 8 when the stop is released as the winding arm is momentarily stationary at the limit of its travel. The take-up means 1 is held against rotation by an electro-magnetically held stop 14 which engages in recesses 13 adjacent the stops 12. While the means 1 is thus held the ring 2 is rotated by a motor 7 via a gear 6 which engages teeth 4 on the ring 2 therby loading the springs of the means 8. As the ring 2 rotates following release of the stop 14, the stop follows the course of a groove 11 until it enters the next recess 13. In a device where the winding arm performs only a reciprocating motion, the necessary rotational motion is performed by the take-up means 1. In this case the ring 2 and motor 7 move together.

Abstract: 1359963 Rock drills A I BAZHAL and L P PONOMARENKO 29 Nov 1972 55175/72 Heading B3C [Also in Division B4] A percussive drill with independent rotation of a drill steel 2 comprises an air-operated redprocating hammer 9 accommodated in a rearhead for striking the spindle 38 holding the drill steel, and an air-operated rotary striking piston 18 accommodated in a fronthead and provided with projections 27 which when oscillated deliver blows to projections 20 of a rotary anvil 17 which is connected to the drill steel as by detents 35 on the rotary anvil in engagement with a drive sleeve 36 and which is connected to the fronthead body 11 by a ratchet mechanism, Fig. 6b, consisting of spring- loaded pawls 34 in an end face of the rotary anvil in engagement with teeth 14 around the body. When the rotary anvil 17 moves through an angle α, the ratchet pawls slip over the teeth 14 through the same angle and lock the rotary anvil with the drill steel in each new position to prevent a reverse oscillating movement of the rotary anvil and drill steel caused by the resilient reaction of the drill steel under torsional forces while rock drilling. Compressed air for oscillating the rotary striking piston 18 is supplied through an inlet 15 and exhausted through an outlet 16, annular air distribution, and exhaust passages 21, 22 being provided in the outer surface of the rotary anvil for communicating with radial inlet passages (23, 24) Figs. 5a, 5b (not shown), and radial outlet passages (25, 26) of the rotary anvil. The rotary striking piston 18 is rotatable in the bore of the rotary anvil 17 and is provided with longitudinal passages 28, 29, Fig. 3b which place working stroke chambers 30 and return stroke chambers 31 in communication with either the inlet passages (23, 24) or the outlet passages (25, 26). In operation, when air is admitted through the inlet 15 of the fronthead it flows through the annular passage 21, radial passages (23) and longitudinal passages 28 into the working stroke chambers 30 to rotate the projections 27 into engagement with the projections 20 on the anvil. During this working stroke, the return stroke chambers 31 are initially connected to exhaust through the longitudinal passages 29 and the air supply is cut off to the working stroke chambers 30 before the return stroke chambers 31 are connected to the air supply. To prevent "dead centres", the radial passages of the rotary anvil are offset with respect to the longitudinal passages of the rotary striking piston. The drill may be mounted on a feed device (4), Fig. 1 (not shown), supported on a trolly (5), the air being supplied independently to the rearhead and fronthead at (A) and (B).

Catalysts mentioned include combinations of nickel and tungsten, preferably sulphided, on alumina, and nickel, cobalt and molybdenum on alumina. Up to 5% by weight of fluorine may be included.

Abstract: 1,161,070. Rocket motors. HAYES INTERNATIONAL CORP. 6 Dec., 1967, No. 55437/67. Heading F3A. [Also in Divisions F1 and G4] In a solid/hybrid rocket motor (Fig. 1) a fuel body 13 includes its own oxidant while a fuel body 14 requires an external oxidizer from tank 17 over valve 18 which is closed at ignition so that fuel 13 burns intially. The chamber pressure 11 is measured by transducer 19 deriving an electric analog signal Ei which is integrated at 21 to E o  = AsE i  dt and compared at 22 with a reference electric signal E r  analogous to a predetermined value of total impulse. When E o  # E r , comparator 22 develops a control electric signal to open, valve 18 to admit oxidant for the second fuel and a timer 23 closes the valve after a predetermined time to close valve 18 and terminate combustion of a fuel unaffected by temperature. If the fuel is so affected the integrated signal E o  is applied to a second comparator (not shown) to terminate combustion after a second predetermined value of total impulse has been reached. The comparator (Fig. 2, not shown) comprises an amplifier with regenerative feedback receiving E o  and E r  over summing resistors with earthed bipolar overload limiting diodes which saturate to produce a constant control signal when Eg > E r . The sevice is applicable to other forms of reaction motor, and may alternatively operate pneumatically or hydraulically.
