Title: Moulding tool coating system - sprays lubricant onto working surfaces intermittently and briefly before each compression operation
Inventor: VOSS GUNTER M
IPC: B30B15/00
Filed: 1978-03-23
Abstract: The system sprays a coating of lubricant in solution, fusion or suspension onto dies and punches used in the manufacture of moulded items. Before each compression operation, the lubricant is deposited on the working outer surfaces of the tools by means of nozzles working briefly and intermittently. The nozzles can spray a single substance, or use compressed air, steam or gas as an entraining medium for the lubricant. As alternatives, deposition can be effected by an ultrasonic oscillator, or a continuous jet can be divided into successive ones by a perforated disc driven by a synchronous motor.

Title: Shearing machine or guillotine for cutting wide metal sections - imparts combined vertical and lateral motion to shearing blades
Inventor: ZWICK GERHARD
IPC: B23D23/00
Filed: 1978-09-01
Abstract: A shearing machine or guillotine for shearing wide metal sections has two side members which guide a frame. The latter is in the shape of an inverted U and is driven from an overhead crankshaft. A blade is fixed to the U frame and slides towards a second blade as the U frame moves downwards. The second blade is attached to a beam which is mounted on hinged jacks. As the U frame approaches the end of its stroke the rounded end engages a recess of a hinged bracket. This causes the frame to move sideways so that a sideways motion is imparted to the shear blades carried by the frame and produces a cleaner cut through the metal section.

It is for a ski-lift shackle suspended on a circulating cable with spring-operated winding gear. A catch fork is movable guided between pick-up position and lower delivery position against return spring force. In the delivery position there is a fork- or shackle-activated release mechanism to carry the shackle over into a rail guideway at an entry point, at about thigh level for an adult skier. The fork guide can have a straight path at an angle to the horizontal.

Title: Insulated layered window or door composite profile - has shaped metal spacers in half shell recesses to hold centre layer
Inventor: DIEHM WALTER
IPC: E06B3/263
Filed: 1978-11-15
Abstract: Two half shells are interconnected by one or more intervening heat-insulating layers to form a single entity.

Title: Removal of foreign bodies from material stream - uses transmitter and receiver to detect presence of different material
Inventor: KNUTH MANFRED DR ING
IPC: B07C5/36
Filed: 1979-01-26
Abstract: Foreign bodies e.g. stone or metal particles are removed from a stream of material (3) by allowing the material to fall between a transmitting device (2') and a receiver (2"). The transmitting device may transmit an electro-magnet or a sound wave. Any foreign body in the material stream changes the signal received by the receiver. The receiver is connected to an electronic circuit which controls a hydraulic actuator (11). This actuator extends a defelctor plate (7) at the instant that the foreign body is passing the transmitter so that it is deflected away from the receptacle (9) into the separate receptacle (12).

The heat produced by the element (14) melts away the ice and thus frees the lock. The leads (18) to the heater element are pref. connected through two switches, a main switch (22), which may be switched on during cold weather periods, and the operating switch (24). The leads are connected to the car battery.
