Abstract: An endoscope has a shaft (4) detachably connected to a handle (2) to enable the shaft (4) to be detached for repair or maintenance. The shaft (4) and handle (2) are detachably connected by spring-loaded latches (10) in the handle which are frictionally engageable with pins (8) projecting from the coupling face of the shaft (4). An external locking sleeve (20) prevents inadvertent separation of the shaft and handle. Illuminating light and the image to be viewed are coupled across the handle/shaft interface by abutting ends of fiber optic bundles (76, 80, 86, 92). The shaft (4) can be flexed by adjustment of manual controls on the handle as a result of racks (40, 44) in the handle (2) exerting a pushing motion on racks (50, 52) in the shaft (4), this pushing motion being transmitted into a pulling action applied to flexure wires (66, 62) extending in the shaft by virtue of pinions (54, 56) interconnecting the two racks of each pair of racks (50, 52) in the shaft (4). An alternative embodiment (FIGS.

Abstract: A high pressure, high temperature reactor device having a pair of spaced tube sheets for supporting a tube nest, one tube sheet being formed with a bellows to compensate for expansion and contraction of the tube nest longitudinally during temperature changes and the second tube sheet supporting the opposite end tubes of the tube nest, with injector tubes mating with each reactor tube and projecting through the reactor shell.

Abstract: A simple, inexpensive gun-type dispenser is disclosed whereby purchased cartridges of heat softenable adhesive or sealant compound can be heated and dispensed during non-commercial projects such as crack sealing or gluing of components by a home handyman. The dispenser comprises a barrel having a breech with an axially aligned opening therein for the loading of cartridges of the compound to be dispensed, a breech access for uncovering the breech opening and for closure thereof after the insertion of a cartridge, electrical heating elements for heating the outer end of the barrel, and a mechanical feeder for urging the compound into the heated end of the barrel.

Abstract: An anode configuration, anode basket and method of packaging anodes within the basket.

Abstract: A method or process for transferring finely divided solids from a first location under the influence of atmospheric pressure to a second location under the influence of pressures of the order of 500 to 10,000 psi.
