Title: Protective external covering for pipes - has steel outer cover connected to inner plastic conveying pipe only at ends
Inventor: DRUCKREY WOLFGANG
IPC: F16L58/10
Filed: 1973-08-22
Abstract: The covering is intended for pipes that convey plastic material, such as hardening material for concrete. It has the advantages that adherence of concrete to the cover is largely prevented and the pipe is easily cleaned. The pipe and outer cover only contact one another at the ends. The connection between the two is simply achieved by warming and widening the end of the plastic internal pipe so that it presses against the steel cover. Concrete which would tend to stick and harden on the inner wall of the plastics liner is prevented from doing so by the resiliency of the material.

Patent DE-2403031-A1 (DE)
Title: Lock preventing unauthorised opening - has two part key to initiate primary and secondary unlocking modes
Inventor: YOSHIZAWA KENZO
IPC: E05B35/14
Filed: 1974-01-23
Abstract: The first rotation of the key together with the rotary shaft through an angle causes the first engagement element to engage with the first mating engagement member thereby making preparation for unlocking, and the subsequent rotation of said key through a certain angle causes the second engagement element to engage with the second mating engagement member so that the actual unlocking is effected. The engagement between the second engagement element and its mating engagement member becomes possible only when the unlocking preparation action takes place. The lock is thus protected against unauthorised opening by using false keys and allows many locks requiring different keys to be made from the same basic components.

Patent DE-2429738-A1 (DE)
Title: Nailing unit for case-making machine - has slipway fixed to pipe down which nails slide under own weight
IPC: B31B1/60
Filed: 1974-06-21
Abstract: Nails are required singly in the pipe, which moves forward to insert the nail in the case- unless, as sometimes proves preferable, the case is advanced against the nail. In the original design the nails had to be turned over from end to end, and the pipe turned through 90 deg. to receive them. Both these operations have been rendered unnecessary by installing a slipway fixed to the pipe down which the nails slide under their own weight. The permanent magnet used to hold the nail in position at the front end of the pipe, has been replaced by a sliding shutter or disc. The nail comes to lie against it because the pipe is tilted downwards slightly.
