Title: Chair with foldable arm-rests - with double ball joints between arm-rests and side struts of backrest
Inventor: BACHT KLAUS
IPC: A47C3/04
Filed: 1973-07-07
Abstract: Chair has a pivotable backrest, and the arm-rests jointed to it can be latched in different positions on lateral supports, from which they can be separated, and are pivotable relative to the side struts, as in 2237641. Preferably the double ball joint is a universal joint. This gives a greater degree of freedom for the flap and pivoting motions of the arm-rests than the sleeve bearing the joint connection. The arm-rests are latched in a convenient position. To incline the backrest forward or backward, the armrests are easily lifted and correspondingly displaced relative to the latch. On lifting, the arm-rest pivots only in the perpendicular pivot plane of the double joint.

Title: Bar length monitoring system for rolling process - evaluates finished length from emerging length before the whole bar is finish rolled
Inventor: KLEIN GUENTER
IPC: B21B15/00
Filed: 1973-10-13
Abstract: Rolled material is measured by the monitoring appts. during the actual rolling process, and it analyses the material before it emerges from the rolling plant and reaches a downstream connected cutter. This arrangement yields early and accurate information about the material still to be rolled and it controls the machinery used for cutting the material to required lengths. The appts. predicts the finished length while it is still rolling and actuates means for preventing excessive cooling of the rolled material and also yields advance information about the material losses in the form of cut off lengths at the start and finish, to ensure economical parting of the finished length into commercial lengths. The distance between the rolling plant and cutter is very short and the hot material leaves the rolling plant into the shears. Photoelectric cell are arranged downstream of the rolls, and a photoelectric cell arranged upstream of the rolls reports the start and end of a bar.

Title: Cylinder lock preset by different key - has spacing elements pressed on resetting by springs into key notches
Inventor: FRANKE HELMUT DR
IPC: E05B27/00
Filed: 1973-11-02
Abstract: The cylinder lock with presetting features is used in situations when keys have to be changed in order to prevent unauthorised access without changing locks. Such situations can be railway station lockers, hotel rooms etc. The lock has a number of spacing elements in the form of spring loaded cylindrical rods or balls. The depth of these components corresponds to a depth stage of the key notch. The spacing elements are pushed from the core pin bores into the aligned storage channels when a new key is inserted. The lock has a hollow cylinder which is able to rotate within the cylinder housing. The enclosed central cylinder has a longitudinal slot for accommodating the key. This central cylinder contains tumbler pin bores in which pins of fixed length slide. On inserting a key an appropriate number of these spacing elements are displaced into the storage channels against the load of the spring. This lock can hence be modified without dismantling and merely by inserting a different key while the lock is opened.

Title: Jolt-squeeze sand moulding machine - using additional air cylinder to absorb the shock from the jolt
Inventor: GROLLA HERBERT
IPC: B22C15/10
Filed: 1973-11-22
Abstract: The machine consists of a frame supporting a moving jolt-table fitted with two circular skirts; the inner skirt fuctions as a cylinder round an anvil used as a piston, with an impact surface mating with the bottom surface of the cylinder. Compressed air is used to raise the table, and the anvil can also be raised be means of a piston housed in a pneumatic damping cylinder beneath the anvil. In its lowest position, the anvil rests on the top rim of the pneumatic damping cylinder but when the piston in this cylinder raises the anvil the air beneath the piston provides a cushioning or "spring" effect. The outer skirt on the table forms part of an annular cavity which is filled with air thereby raising the table still higher for squeezing the sand in the moulding box. The pneumatic cylinder absorbs part of the holt so it is not completely transferred to the foundation on which the machine is placed.
