Title: Implement for displacing fodder on ground - uses rotors mounted on beam inclined to ground their height increasing in direction fodder movement
Inventor: ARON JEROME
IPC: A01D78/10
Filed: 1982-04-08
Abstract: The implement may be mounted on the rear of a tractor and is designed to displace fodder lying on the ground. It comprises an elongated support frame (1) equipped with rotors (11-14) which are imparted with rotation during operational phases. The rotor axes are inclined to the vertical and the support is not parallel to the ground, the effect of support inclination being that each rotor has a different effective height. The support may subtend an angle (alpha) of some three degrees with the ground and may rise in the direction in which fodder is displaced. The rate at which rotor height varies is uniform.

Title: Fixture for three dimensional structures - has pairs of U-shaped elements welded into three principal axis
Inventor: NASI CESARINO
IPC: E04B1/24

Abstract: The node has three assemblies (X,Y,Z) of paired hollow or U-shaped elements (3x,4x,3y,4y,3z,4z) the pairs of each assembly being welded together parallel but spaced to allow a cross formation without interruption of material. Each pair traverses the space existing between the other pairs and each piece has a number of holes (6-13) allowing the attachment of profiles (p) of square or circular cross-section. The assembly allows profiles to be introduced without deformation in the hollow elements or between two hollow elements of the same assembly.

Title: Combined trigger and safety catch mechanism for abattoir pistol - is automatically self-setting each time firing pin is loaded
IPC: A22B3/02
Filed: 1982-05-11
Abstract: Safety catch mechanism for an abattoir pistol of the type comprising a hollow, cylindrical breech partly surrounded by a coaxial, knurled sleeve. Within the breech a firing pin can be spring-loaded by axially displacing the pin until a shoulder on the pin engages a stop. The stop is a collar through which the pin is axially slidable. The collar is pushed into engagement with the collar by a spring. A cam surface on a pivoted lever can be used to move the collar out of engagement with the shoulder so that the firing pin is released. The lever serves as a combined trigger and safety catch. The lever is telescopic and cannot be pivoted sufficiently to release the firing pin until the lever is oulled out to an extended position. Before extension, a buffer stud limits pivotal movement. When extended, the stud can move into a cavity or clear space to allow increased pivotal movement. To allow increased pivotal movement. Pref. the telescopic extension of the lever is against spring pressure sufficient to retract the extension. Although the device is simple and inexpensive, the safety catch is automatically self-setting each time the firing pin is loaded. After that, the pistol cannot be fired until the catch is released which requires the lever to be telescopically extended.

Title: Preheating audio or video disc moulding materials - by intermittent induction to minimise heat losses and temp. differentials
Inventor: NEUMAN MARCEL
IPC: B29C43/52
Filed: 1982-05-26
Abstract: In a compression moulding process for producing audio or video record discs, the material is brought to temp. by a succession of brief high frequency induction heating impulses during which the blank disc may also be compressed to bring it to the correct size and temp. for definitive shaping and cooling while using sustained compression. Used for moulding gramophone or video discs from thermoplastic moulding materials, having a high dielectric loss tangent, such as PVC, cellulose acetate, acetal polymers, etc. Reduces heat use and losses compared with processes in which heat transfer for heating and cooling is effected by conduction involving bulky metallic components in significant repetitive temp. changes. Use of intermittent inductive heating results in a more uniform temp. distribution than continuous induction, by reducing the effects of preferential heat adsorption by any relatively warm material having thereby an enhanced dielectric loss factor.
