Title: Differential master cylinder for vehicle brakes - has chargeable piston reservoir, back pressure valve and working piston in cylinder
Inventor: OBERTHUER HEINRICH
IPC: B60T11/224
Filed: 1974-07-31
Abstract: The design overcomes the disadvantage that rapid operation of the brake can cause premature operation of the over pressure relief valve. It also reduces the risk of failure due to sealing loss. There is chargable piston into which fluid is forced out of a reservoir via a back pressure valve. The piston moves in a cylinder and operates a second working piston. The closing force is reduced by a spring operating on the pressure relief valve. The latter valve is acted on only by the pressure in the fluid reservoir and is fitted in the centre of the chargeable piston. A ram (34) of the valve projects through an opening in the reservoir.
Patent DE-2439998-A1 (DE)
Title: Pressed sheet steel wall profile - has folded flanges for improving wall profile stiffness
IPC: E04C2/08
Filed: 1974-08-21
Abstract: The wall elements are used for constructing especially hall or shed walls, and the pressed profiles have stiffening grooves to increase their bending stiffness without increasing the depth of the stiffening ribs and without increasing the thickness of the walls. The flanges (5, 6) which are bent at the edges (4) of the channel shaped panels are folded over one or more times for increasing the stiffness and they can be used for connecting the edges of these profiles on building up a wall. The additional stiffness ensures resistance to high wind loads and fewer vertical supports are needed for supporting the wall.

Title: Machine readable coding of electrical components - using magnetic or optical methods allows identification for automatic assembly processes
Inventor: GOEBEL ROLF
IPC: H05K1/02
Filed: 1975-10-21
Abstract: A general method is used for coding of electrical components e. g. capacitors and resistors, such that automatic code recognition can occur to identify a specific component. The method of coding proposed is either based upon magnetic particles within a top varnish coating layer or else a magnetic film covering. Either coating technique lends itself to automatic scanning by a sensing head. Depending upon the sequence of information received from the sensing head, a decision may be made to identify the component and also itself relative orientation. Once identified the component may be manipulated into the correct position for assembly on a circuit board.

Patent DE-2558836-A1 (DE)
Inventor: RUEDENAUER WERNER
IPC: F42C11/02
Filed: 1975-12-27
Abstract: The electrical detonator is provided with a piezoelectric voltage pulse transmitter which supplies a voltage pulse, corresponding to the braking moment, as a result of the sudden braking when the projectile strikes the target. The pulse transmitter is located in a detonator body (1) which is located in the nose of the projectile (3) and in whose tip a pulse transducer is arranged. The pulse transducer contains a nose part (7) having a cylindrical recess (11, 12) which expands in the shape of a funnel at the front and whose front edge is designed as a sharp gripping edge (10) and in whose cylindrical section a plug (14, 17) is inserted which covers the funnel-shaped expansion, overhangs the nose part and consists of a plastic material which can be deformed elastically. The sharp gripping edge causes the projectile to "stick" to the target object if it strikes at a flat impact angle, and the elastic plastic plug is intended to supply impact damping for those cases where the projectile strikes "soft" targets (foliage, rain etc.) and thus no detonation is intended to occur. <IMAGE>
