Title: Detonation system for underwater projectile - is actuated by hydrodynamic pressure acting on piston in projectile nose
Inventor: PLEINES KARL-HEINZ
IPC: F42C15/29
Filed: 1986-07-30
Abstract: An underwater projectile (1) has a detonation system (2) which is actuated by the hydro-dynamic pressure acting on the ose of the projectile.

Title: Method of producing a treatment atmosphere, and plant and device intended to perform the method
Inventor: BLAUDSZUN BERND DIPL ING
IPC: A61F7/00
Filed: 1986-10-03
Abstract: The invention relates to a method of producing a treatment atmosphere for the treatment of patients suffering from rheumatic disorders by low-temperature therapy. The therapy gas, e.g. nitrogen, oxygen, noble gas, hydrocarbon mixture or the like, is liquefied in a heat exchanger by temperature cooling. For local treatment, the liquid gas removed is kept at a temperature, by adjusting the cooling medium to which the heat exchanger is exposed, such that the gas stream impinges on the body surface to be treated in a homogeneous gas phase. For treatment of the whole body, a treatment atmosphere is mixed in a ratio corresponding approximately to that of normal air, of liquid oxygen to liquid nitrogen and then fed to the treatment cabin in a volume flow-controlled manner.

Title: Simple antitheft device for automatic vehicles and car radios
Inventor: OHM KLAUS DR
IPC: B60R25/00
Filed: 1987-12-18
Abstract: To provide protection against theft, door locks, alarm systems, electronic locks, mechanical steering wheel locking devices have hitherto been used, while car radios have been protected by means of safety cassettes, devices for carrying the radio when the vehicle is exited, electronic safety devices which make the car radio unusable etc.. The new antitheft device is intended to be simple, practical and cheap. The car and car radio can be protected in an amazingly simple manner by inserting a bore hole in the gear lever and/or its safety button. If the gear lever is placed in the parking position P and the U-shaped piece of a padlock is passed through the bore hole when required, the gear lever cannot be moved out of the parking position. The car is therefore secured and the car radio cannot be pulled without difficulty out of the radio slot owing to the fact that the blocked gear lever is situated in front of it. Antitheft device for automatic vehicles and car radios.
