Title: Improvements in or relating to shell fuzes
IPC: F42C15/20
Filed: 1941-03-28
Abstract: 548,304. Shell fuzes. STIRLING ENGINEERING CO., Ltd., GRAY, C. L., and JOHNSON, C. H. March 28, 1941. Nos. 4216/41 and 3522/42. [Class 9 (i)] A shell fuze for attachment to a shell comprises a casing A, B with a screwed portion for attachment ot a shell, a striker casing 7 for enclosing the striker 6 and a percussion cap 8, a cross pin 11 engaging an aperture in the striker, an annular inertia plate 17 to retain the cross pin in the stop position, and a ball 2 engaging conical recesses in the cap 1 of the casing and in the end of the striker. The inertia plate has one edge engaging a niche A 2  on one side of the casing and is provided with a projection 16 having a key hole slot 15, the enlarged portion 15a of which is normally engaged by a safety pin 20 carried by an adhesive band 21 attached to the casing. The cross pin is provided with a head 12 engaged by a spring 13 in a recess in the casing and with a recessed end 14 adapted to be engaged by the key-slot in the concussion plate. As the shell is placed in the gun, the adhesive band is ripped off, so that the safety pin 20 is withdrawn from the inertia plate which is then freed, so that as the gun is fired the inertia plate sets back and releases the cross which is ejected.. By this time however, acceleration has ceased and so the firing pin is not pressed forwardly by the ball; on impact, however, the ball presses the striker against the percussion cap 8. In order to prevent accidents in case of misfire or to prevent the cross pin being ejected before the shell leaves the gun a bow spring 30 is adapted to be pressed by the gun barrel 31 against the end of the cross pin.

Abstract: 287,131. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. March 16, 1927, [Convention date]. Shaping glassware after formation.-Relates to a machine for melting-off the waste portions of glass bulbs after they have been blown and before they are made up into electric lamps. According to the invention, the devices which hold the bulbs grip them by suction, and means are provided for centering the bulbs in the holders, and for removing them from the holders when they are finished. The machine comprises a carrier 7 which is rotated intermittently about a shaft 4 and is provided with bearings 8 in which hollow bushes 9 are journaled. Pinions 10 secured on the bushes engage a gear wheel 11 mounted on, and constantly rotated by, the shaft 4. The bushes 9 have cupped lower ends that engage the bulbs 25, and they are also formed with slots 12 by means of which their interior spaces communicate with passages 13 formed in the carrier 7 and thence with a vacuum tank. Brackets 21 are secured to the carrier adjacent to the holders 9 and carry adjustable lugs 22. A pin 18 slides into the hollow interior of each holder 9 and is normally pressed upwards by a spring. In use, a bulb is pressed against the cupped end of a holder 9 and is held by suction. The holder is in constant rotation, and unless the bulb is correctly centred, it is brought into contact with a lug 22. which is so adjusted as to straighten the bulb in the holder. A burner 23 mounted on the table of the machine then fuses off the glass at the neck of the bulb. Movement of the carrier 7 eventually brings the bulb beneath an arm 20 which projects over the carrier. This arm engages the upper end of the pin 18 and presses it downwards, thus causing it to eject the bulb from the holder.

Abstract: 1,131,072. Aircraft navigation computing. SMITHS INDUSTRIES Ltd. 7 Feb., 1966 [5 Feb., 1965], No. 5080/65. Heading G4G [Also in Division H4] In an aircraft navigation instrument a signal representing the difference between actual aircraft height H and the sum of the height H d  of a predetermined destination point and the change C in height to the destination point is derived and utilized to actuate an indicator index 12 or an automatic pilot 15. The quantity C is obtained utilizing a distance measuring equipment 1 in the aircraft in conjunction with a responder at the destination point and a potentiometer 3 into which the desired flight slope is set in manually. The distance-to-go signal is differentiated to give ground speed and the latter, together with the former and a correction signal (allowing for change in height) controls a " time-to-go " index 20 on the aircraft clock. The ground speed signal is multiplied by the desired flight slope to afford control of a further index 18 representing required rate of change of height relative to that correct for the desired flight slope. The actual height H is taken from a barometric altimeter and the H d  signal is corrected for actual ground level air pressure at the destination point. Switch 2 is normally closed but is opened at the destination so that automatic pilot 15 can maintain the aircraft at height H d . The invention may be applied to ascending as well as descending paths; such paths need not necessarily be in a single straight line. The use of dead reckoning up-dated by a Doppler system is mentioned; the use of a hyperbolic radio navigation system is also mentioned.

Title: Improvements in or relating to the reduction of iron oxide
IPC: C21B13/08
Filed: 1961-02-10
Abstract: Iron oxide is reduced to a lower state of oxidation at a temperature between 750 DEG C. and incipient fusion in the presence of excess carbon and a dolomite or limestone flux, by carbon monoxide generated in situ by partial combustion of the carbon: an auxiliary fuel with the requisite oxygen is fed to maintain a uniform temperature in the reduction zone.  The iron oxide is at least 3 mm. in size and may have been pelletted and subjected to an oxidizing roast to remove sulphur.  The carbon, e.g. anthracite, has a particle size of 12 mm. or less and the flux, present in at least 4% of the charge, has a particle size of 1 to 3 mm.  Reduction is preferably effected in a rotary kiln, the charge being fed countercurrent to the burning auxiliary fuel which may be fed in axially as well as at spaced intervals along the kiln, in the form of oil or gas, for example town gas.  The reduced ore is preferably passed through a rotary cooler countercurrent to town gas which is then fed to the output end of the rotary kiln.  The reduced ore may be coated with graphite or lime, or both to prevent oxidation.ALSO:Iron oxide is reduced, so that 85-95% of the iron content is metallic, at temperatures between 750 DEG  C. and incipient fusion in the presence of excess carbon and a dolomite or limestone flux, by carbon monoxide generated in situ by partial combustion of the carbon; an auxiliary fuel with the requisite oxygen is fed to maintain a uniform temperature in the reduction zone.
