Title: Pencil case with swivel mounted pencil holder - has U-shaped spring walls holding pencils in position for easy removal
Inventor: MUELLER EMIL
IPC: A45C11/34
Filed: 1974-09-20
Abstract: The pencil or pen case has a swivel mounted insert (16) by means of which the pencils can be held secure even when the case is tipped up. The insert (16) preferably has a U-section with a base wall (24), an upper wall (20) having longitudinal slots and a rear wall (26) connecting the other two walls together. A resilient tongue (22) can be mounted between each two longitudinal slots (18) in the upper wall (20) so as to press the pencil against the base wall (24). In this way each pencil can be secured independently of the others so that they can easily be removed individually. Since the insert can in any case be swivelled up out of the case the removal of the pencils is made much easier.

Title: Fire damper for ventilation ducts - has material forming a foam at high temperatures in vapour proof sachets
Inventor: PETRI KLAUS ING GRAD
IPC: A62C2/06
Filed: 1975-07-04
Abstract: The damper has a circular casing whch flanges into a section of the ventilation duct. Within the casing a grid is placed perpendicularly to the direction of air flow.

Title: Sonar target position tracking system - uses sound receptors in submarine and torpedo to enable triangulation calculations to be performed
Inventor: MATUSCHE HEINZ DR
IPC: G01S5/20
Filed: 1975-11-08
Abstract: The system is used for tracking the position and speed of moving objects at sea, such as submarines and torpedos.
