Title: Barrel for converting shotguns for firing bullets - has separate cartridge chamber and joint for aligning with aiming system
Inventor: RADAU ALWIL
IPC: F41A21/10
Filed: 1975-04-29
Abstract: The insertion barrel is used for converting shotguns for firing different calibre ammunition preferably cartridges. This ensures that a shotgun can be readily adapted to the ammunition required by law for hunting certain animals. The inserted barrel can accommodate also higher gas pressures which exceed 2600 bar. The inserted barrel is readily adapted to the existing aiming device and the barrel is firmly held without need for readjustment. The inserted cartridge chamber and inserted barrel are separate components. The cartridge chamber has a bullet channel which projects into the barrel and this channel is aligned by a ball joint with the barrel guiding the bullet. The ball element forms an integral part of the inserted barrel and the projection has a seat for the ball.

Title: Sealing label for filled bag - is fitted over mouth between two filling nozzles and sealed lower down
Inventor: THUERLINGS FRITZ DIPL ING
IPC: B65B51/04
Filed: 1975-05-07
Abstract: The method of applying a sealing label across the open mouth of a filled bag, includes the use of four filling nozzles which stretch open the mouth of the bag, holding it up during filling, then are rotated to allow the bag to sink onto a support. Two nozzles are longer than the other pair, and remain in engagement with the mouth of the bag, and stretch it while a folded label is lowered between them, and pressed against the sides of the open mouth, thus sealing the filled bag. The label has a cut-out each end of its fold line, to clear the two nozzles. The label is deep enough to seal the bag below the level of the nozzles.

Title: Dynamic mounting for lorry load surface - with support frame fitted to chassis on three pivot points
Inventor: EYERLE ANTON
IPC: B62D24/02
Filed: 1975-07-31
Abstract: The load surface of the lorry is bolted to a rigid support frame which is mounted on the chassis using three pivot points. A front pivot point is located in the centre line of the lorry, between front and rear axles, and pivots about a longitudinal axis. The two rear points are at the rear corners of the lorry and pivot about transverse axes. The system isolates the load surface from chassis torsitional twisting over rough ground.

Title: High speed camera focusing system - uses setting wheel with recess with standardised positions which can be felt
Inventor: SCHEUERER JAKOB
IPC: G03B13/18
Filed: 1975-08-04
Abstract: The device is used for accelerating the setting of the focus of a camera. It may be in the form of a dimple-like recess, or in the case of larger camera a profiled wheel, on the lens, so that the setting can be sensed with the fingers and if required altered while the camera is being moved towards the eye. When the dimple-like recess is at the top of the lens, the setting is long distance, and when it is in the 9 o'clock position, the distance setting is 5-7 m. The same positions apply to a profiled wheel. This device saves time when taking snapshots as the photographer need not take his eye off the view.

Title: Steering for large wheeled skip trailer - with interlocked hydraulic steering using double action rams with balanced pressure in each
Inventor: OLIVETTI GUISEPPE
IPC: B62D7/06
Filed: 1975-11-07
Abstract: The large wheels of the skip trailer have at least two wheels, on the same axle line, steerable, without any direct mechanical link between them. The steerable wheels (2) are steered by double action rams (1) linked to the wheel support and controlled by a hydraulic circuit which ensures equal pressures in each ram. The hydraulic circuit is protected by a set of valves which can lock the two rams in the ahead setting for normal towing. If steered then the rams operate in equal and opposite directions for accurate tracking. The system allows fine steering control with large suspension displacements, as on rough ground.

Title: Slow moving cam switch for storage heater - has upper and lower plates connected by spring (OE150876)
Inventor: BAEUML WALTER ING
IPC: H01H19/62

Title: Automatic brake for pallet shelving tracks - uses centrifugal force of pendulum to act as friction brake above preset speeds
Inventor: JUERGENS WALTER DR ING
IPC: B65G13/075
Filed: 1976-05-04
Abstract: The brake for pallet shelving acts as a friction brake by using centrifugal force so that it only blocks and thus brakes the castors on which the transported goods are moved from a certain adjustable speed. A pendulum is mounted on an axle of a wheel and swings to a greater or lesser extent independence on the movement and speed of the castor. When the latter is moving at a sufficiently high speed the pendulum swings so far that is is stopped by a barrier to act as the brake.

Title: Compensated air velocity meter using thermistors - has differential heating corrected in bridge using feedback amplifiers
Inventor: BROEZEL RUDOLF
IPC: G01P13/02
Filed: 1976-06-18
Abstract: The compensated air-velocity meter consists of a pair of thermistor probes in line in a detector tube. Each thermistor is connected into a bridge circuit containing a standard resistor and a differential amplifier. The output of each amplifier is fed back to the bridge so that the temp. of each thermistor is equal to that of the other. This compensates for differential heating of the thermistors which would otherwise occur. The feed-back voltage component of the amplifiers is tapped off and fed to a comparator whose output signal is proportional to the air-flow velocity in the tube. The device can be used as a rate-of-climp indicator in aircraft.

Filed: 1976-06-24
Abstract: The yarn cutting mechanism on a creel, supporting a number of bobbins supplying yarns to e.g., a warping beam, has two cutting blades of creel height, each fitted with powered oscillating cutting teeth. The mechanical yarn cutting is activated without using the yarn holding arms and without requiring a small gap between the spool frame and the tensioning assembly. The yarn cutting mechanism is continuously mobile. The cutting teeth are pointed or rounded in the direction of travel, and are set as saw teeth, while projecting blade carriers cover the bases of the toothed sections. The cutting blades and/or the blade carriers are mounted on rollers at top and bottom riding in slits and guide rails in the tensioning assembly, a common drive being used to move the cutters for positioning and to oscillate the cutting teeth. The drive is positioned at the top guide slit of the unit, and can be arranged to drive only one blade.
