Abstract: 1,065,668. Magazine slide projectors. FOTEK CORPORATION PTY Ltd. June 30, 1964 [July 12, 1963], No. 26997/64. Heading G2J. A slide projector has a slide changing and magazine indexing mechanism in which a manually or motor-operated saddle 20 as in Fig. 7 moves normally to the optical axis and causes a slider 28 to move parallel to said axis when the saddle is displaced in that direction by engagement of cam slot 19 with pin 17 Fig. 4 on the rod 16 of slide pusher 14, this displacement of saddle 20 indexing the slide magazine 15 through the engagement of pin 21 Fig. 4 with rack 22 Fig. 7. Slots 24, 25 in saddle 20 engage projections 26, 27 of slider 28 below whose longitudinal part has slots 29, 30 receiving studs 31, 32 fixed to the projector base. Manual operation Slide pusher 14 is driven forward by handle 13 to the full-line position of Fig. 4, pusher 14 entering a slot in the magazine 15 to transport a slide to the projection gate. The turned end 18 Fig. 7 of pin 17 returns the slide to the magazine when handle 13 is withdrawn, and pin 17 then engages cam slot 19 as above, for magazine indexing. Motor-driven operation Cooling fan motor 33 Fig. 1 has a belt drive to top pulley 37 which drives a lower disc through a solenoid 45 operated slipping clutch Fig. 4, whereby pinion 40 on the spindle 39 is rotated to drive turntable 42 by meshing with ring gear 41. Pin 43 on the turntable engages slot 48 in a follower 44 fixed to rod 16 of the slide pusher which is thereby oscillated as the turntable rotates. The slides are thus changed and the magazine indexed as above. After one cycle, detent 46 actuates micro-switch 47 to de-energize solenoid 45. To change the slide, the solenoid is switched on by the operator. To change to manual operation, pin 43 is dis-engaged from slot 48. Blind 49 covers the gate when no slide is contained therein. Objective lens 1 is focused by friction roller means controlled by knob 9, the lens barrel moving on four supporting wheels.

Title: Improvements in or relating to sleeve-valve two-stroke internal combustion engines, operated in conjunction with exhaustdriven turbo-blowers
IPC: F02C6/12
Filed: 1935-10-02
Abstract: 463,566. Sleeve valve engines; cylinders. KIPFER, P. Oct. 2, 1935, No. 27228. Convention date, Oct. 2, 1934. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine operating in conjunction with an exhaust-driven turbo-blower, each cylinder has two rows of exhaust ports and a single row of scavenging ports controlled by a sleeve valve so that the main exhaust ports, which lead to the turbine, are opened before, and closed substantially simultaneously with, the opening of the scavenging ports and the residual exhaust ports. In Figs. 1, 3, the scavenging ports 10, which are controlled by the upper edge of, or ports in, the sleeve valve are fed by an annular passage 11 ; the main exhaust ports 5 and the residual exhaust ports 8 lead to passages 6, 9, and are controlled by a double row 4, 7, or a single row, of ports in the sleeve valve. The ports 5 may be subdivided into a number of rows leading the exhaust to different turbine rotors, or to different pressure-stages in the same turbine, the arrangement being such that escape round the sides of the piston is prevented. The edges of the ports are rounded in the direction of flow, or kept sharp in the reverse direction. The exhaust and inlet ports 5, 10 may both be at the lower end of the cylinder and controlled by the same sleeve-valve ports, the ports 5 being thus cooled. Diagrams, not shown, are used to set out the relative position, during the cycle of the piston face and the ports in both the sleeve valve and the cylinder. In one arrangement the ports 10 do not commence to open until the ports 5 are closed, they continue to open during the closure of the ports 8 and have their maximum opening at the closure point of these ports. Pumps.-Fig. 6 shows the general arrangement of a radial cylinder engine and turboblower ; the main exhaust stream flows by a short path to the nozzles, after which it is joined by residual exhaust stream, the two streams exerting an ejector action on one another; the exhaust from separate cylinders may be separated by partitions to enhance this ejector action. In a multi-stage turbine the residual exhaust is led in at the place where the exit velocity is a maximum. The charge is delivered by pipes which are curved to fit round the cylinder fins and increase the cooling effect of the air-stream thereon. The cylinders may be in two rows. If the cylinders are in line the turbo-compressor axis is arranged at right angles to the crankshaft axis the turbine blades and the compressor outlet being at substantially the same height as the corresponding ports, there being two or more turbo-compressors to each line of cylinders, the compressors being shared between the lines in V-engines.

IPC: G21C21/16
Filed: 1962-07-16
Abstract: A process for preparing a uranium molybdenum alloy (e.g. Mo 0.3-0.6% by weight, balance U) comprises melting the two metals under vacuum in a graphite crucible covered with a reducing cement (e.g. alumina or calcium zirconate), casting the melt and subjecting the bars or tubes so formed to a heat treatment in a molten salt bath followed by a stepped tempering to produce a grain size of 60-80 microns.  The heat treatment is carried out at 675-800 DEG C. followed by cooling to 550 DEG C., keeping at this temperature for 15 minutes and then cooling to ambient temperatures at the rate of 20-60 DEG C. per minute.  The alloy is stated to be useful as a nuclear reactor fuel element. In the example impurities in the starting materials are as follows:  100 p.p.m. of Al, Fe, Ni, Cr, Mn, 100 p.p.m. Si and 90 p.p.m. C in the uranium and 100 p.p.m. C and 120 p.p.m. metallic impurities in the molybdenum.
