Abstract: ABSTRACT OF THE DISCLOSURE      An avalanche rocket to be fired from a barrel.  The rocket has a case with a nose and a tail and is able to receive an explosive charge, adjacent the nose.  The rocket includes a firing mechanism having a first housing in the case.  There is a piston in the housing able to travel in the housing towards the nose of the rocket and a spring to urge the piston to travel in the housing.  The piston can be stopped at the end of said travel.  There is a releasable safety catch to prevent movement of the piston in the housing and a device to release the safety means as the rocket is launched.  The rocket includes a firing pin and a second housing to receive the firing pin and a detonating charge for the explosive charge in the casing.  A pivotal link attaches the second housing to the first housing and the firing pin is retained within the second housing with a predetermined force that can be overcome, for example, when the rocket lands.

Patent CA-2051342-A1 (CA)
Title: Mobile disinfection installation
Inventor: NOETZEL HANS
IPC: A61L11/00
Filed: 1991-09-13
Abstract: ABSTRACT OF THE DISCLOSURE A   mobile   disinfection   installation   for hospital waste, mounted on a support structure, the installation   has   an   upwardly   sloping  screw conveyor, originating at the base of a feed hopper. A cutting mechanism is  installed in  the hopper. The hopper discharges into a rotary tube equipped with lifting scoops.   At the discharge end of the rotary  tube  a  closed  discharge  housing  with  a discharge device is provided for the disinfected waste and has an exhaust pipe for the treatment medium.  The actual disinfection takes place in the rotary tube  which has  a  large  cross-section  in comparison to the screw conveyor.   In this way, a high throughput capacity can be achieved in the cramped  space  of  a  mobile  installation.   The ascending screw conveyor bridges,  as intermediate conveyor, the difference in height between the base of the  feed hopper  and the  feed opening of the rotary tube.   In this way, it makes it possible to combine the feed hopper, which practically takes up the entire height permissible for a road transport vehicle,  with the rotary tube of which the feed opening has to be at a certain height above its bottom due  to the  relatively large diameter and taking into account the material discharge at the end of the rotary tube.
