Abstract: 1,132,914. Popgun. VICTOR COMPTOMETER CORP. 18 May, 1966 [15 June, 1965], No. 22174/66. Heading A6S. In a popgun of the type wherein, upon firing, a plunger assembly 19 is propelled along barrel 11 towards valve assembly 71, the latter being momentarily opened on contact with the plunger assembly, said valve assembly is spaced from muzzle end 101 of barrel 11 by a distance several times the diameter of the barrel whereby there is emitted an audible ring of air which is sufficiently coherent to produce an accurate and visible effect on targets up to 15 feet from the gun. For instance, the valve may be spaced 5 13/16" from the muzzle, the barrel having an internal diameter of ¥". Preferably the valve assembly 71 comprises cup 73 centrally apertured at 79, disc 81 held against cup wall 75 by spring 83 and having domed recess 89 and projections 91, and elastomeric seal 93 with rearward annular projection 99 which engages piston 25 in its forwardmost position. Spring 83 is strong enough to retain disc 81 against cup wall 75 until struck by rod 36 attached to piston 25, the length of rod 36 being such as to displace disc 81 only a small amount e.g. 1/6400th of an inch, whereby an instantaneous release of air compressed by the movement of piston 25 towards valve assembly 71 is effected causing a loud bang. A washer 37 of absorbent material and forming part of plunger assembly 19 is saturated with oil for lubrication and also has the effect of producing smoke when the gun is fired. The ring of air emitted may be doughnut-shaped.

Title: Improvements in cracking hydrocarbons
Inventor: FLESCH WILHELM
IPC: C10G9/00
Filed: 1954-07-30
Abstract: 785,453. Gasefying hydrocarbons. BADISCHE ANILIN- & SODA-FABRIK AKT.- GES. July 30, 1954, No. 22267/54. Classes 55 (1) and 55 (2). In a process for cracking hydrocarbons in the presence of moving granular heat carriers at about 600‹ to 900‹ C., the entrained finelygrained heat carrier is separated in more than one stage after leaving the reaction chamber. The first separation takes place at temperatures between 400‹ and 600‹ C. such as in cyclones, electrical high-voltage fields or by ultrasonics, practically none of the reaction products being deposited on the heat carrier, and the further separation takes place at such a low temperature that the effluent high boiling point cracking products are separated together with the remain - heat carrier particles. In an example granulated coke is kept in rolling motion in a cylindrical reaction chamber by introducing superheated steam. Oxygen is supplied by nozzles above the grate and a petroleum distillation residue through other nozzles above the first ones, a temperature of 750 ‹ C. being set up in the coke. An attached cyclone separates about 75 per cent of the dust from the gaseous and vaporous products at a temperature of 500‹ C. and returns it directly to the moving bed. After passing through the cyclone separator the gas-vapour stream is injected with a mixture of asphalt and high boiling point oil, the residual dust being washed out with the injected liquids at 300‹ C. to 400‹ C. and returned to the coke bed through the oil supply pipe.

Filed: 1972-05-12
Abstract: 1348609 Controlling position C REICHERT OPTISCHE WERKE AG 12 May 1972 [13 May 1971] 22426/72 Heading G4H [Also in G2] In trans-illumination microscopes using Kohler's principle the device for changing the objectives is connected to the illumination system adjustment drive. The illumination system 2 comprises a set of lenses movable by a motor 24 activated by a signal derived from a change of objective. The objectives 9 are mounted on a support 12 the outer surface of which has for each objective, a notch or groove 14 of different reflective properties. Thus when an objective is changed the reflection of light from a lamp 15 to photo-cell 17 changes, and a signal is fed to a transducer 19. If this signal does not equate with that derived from the present setting of lens system 2, through wiper 22, motor 24 is activated to alter the setting of system 2 to regain balance. Alternatively, rotation of the objective support 12 can also move a collector (29, Fig. 2a, 2b, not shown) into contactor with a resistor associated with the new objective to give an altered output signal which again activates motor 24. In the embodiment the movement of the illuminating lens system 2 to its final position may be indicated visually by lamps (37), (38) or aurally, or it may be shown on a television or other screen.
