Title: Edge trimming knives for thermoplastic floor covering moulds - melt and cut away edges projecting from mould joints
Inventor: LUEBNITZ KLAUS
IPC: B26F3/06
Filed: 1976-07-08
Abstract: In the mfr. of moulded floor coverings pressed out from thermoplastic mats arranged between upper and lower moulds, the material projecting from the joints of the moulds is cut away automatically by heated melting knives arranged with expansion slots between them, in the zone of the joint. The knives set up a configuration corresp. to the contour of the edge of the prod., and contact the thermoplastic material only when the mould is practically closed. The expansion slots in the plane of the knives run at an angle relative to the line of motion of the knives towards the thermoplastic material. The knives may have the form of a parallelogram or of a trapezium. The planes of the knives run relative to the direction of the line of motion towards the thermoplastic material so that after cutting off the surplus, they move away from the edge of the moulding. The knife holders are arranged so that when the surplus edge is cut, they push the material away. The operation of cutting away by hand with a knife the edges projecting beyond the joints of the mould is eliminated. The work is automated and is effected within close tolerances.

Title: Folding door locking system - operates with linkage preventing locking unless all latches are engaged and has two rails held back by pivoting arm
Inventor: BOEVING EGON
IPC: E05C7/04
Filed: 1976-12-18
Abstract: The two adjacent leaves (1, 2) of the door are secured in the locked position by pivoted forks (6, 7) engaging with studs (8, 9). The upper fork pivots (11, 12) mounted on the door frame are connected to the sliding rails (19, 23) by double levers.

Title: Emergency non blocking brake for trailer - has emergency piston with smaller than combined area of relay and braking valves
Inventor: REINECKE ERICH
IPC: B60T15/18
Filed: 1977-02-17
Abstract: The trailer pneumatic brakes are operated by a relay valve and a braking valve. In the event of brake line fracture, the loss in pressure operates an emergency piston valve to apply the trailer brakes. For a stable braking control, the area of the emergency piston is less than the combined area of the relay and braking valve. The emergency braking action is thus modulated w.r.t. the full braking capability. This prevents the trailer wheels from blocking and causing instability.
