Patent DE-2150182-A1 (DE)
Title: Drilling rig control system
Inventor: BROMELL RAYMOND JOHN
IPC: E21B44/00
Filed: 1971-10-08
Abstract: A control circuit for a well drilling rig receives signals representative of drill string torque and wt and acts to sound alarms and shut down the rig if these signals depart unduly from set point signals representative of estimated torque and wt. Mud pump pressure can also be sensed. The circuit functions both during actual drilling and during round-tripping. The abnormal conditions detected include drill string twist-off, "sloughing shale", ledge and bridge encounter in a hole, worn bits and punctured drill string.
Patent DE-2159958-A1 (DE)
Title: Pre-stressed concrete reactor pressure vessel - - utilising sectional spiral construction
IPC: G21C13/093
Filed: 1971-12-03
Abstract: In a pre-stressed concrete cylindrical pressure vessel, in which the wall is constructed in sections wiht sleeves for circumferential and vertical stressing cables, the sections follow a circumferential spiral path with the radial joints stepped and the joint faces set square to the spiral gradient. The stressing cables are tensioned as each section is completed and the cables are extended by jointing to effect continuity throughout the construction. Pre-cast blocks can be used an alternative to shuttering and in-situ concrete pouring. The technique has application in the construction of reactor pressure vessels and the geometry is not limited to cylindrical forms.

Title: Reflective surface glass bulb - has flame sprayed reflective layer
IPC: C03C17/06
Filed: 1971-12-08
Abstract: The glass bulb is given a reflecting surface zone by the flame spraying of a reflecting layer onto the final shape but still warm bulb. The reflecting Cu or Al layer is sprayed onto the bulb surface away from the direction of reflection and is done pref. in a reduced atmosphere. The method is used for electric bulb mfr. It is a cheaper process than the conventional process, where the surface to be coated has to be scrupulously cleaned prior to coating, which is not necessary for the new process.

Title: Weight controlled castings - using computer weight controlled casting ladles
Inventor: EUGEN POELYVUORI LEO
IPC: G01G13/00
Filed: 1972-01-22
Abstract: Casting of fixed weight or size objects is done from a ladle, the weight of which is determined after a stream of metal feeding it has been interrupted. This value is fed into a computer with a memory storage facility which stores it. The figure is used as reference against which is compared the variable produced by the continuously reducing weight of the ladle during casting, which is stopped when a pre-set figure is reached. Feeding of the casting ladle is pref. done via a storage ladle interposed between the continuously discharging furnace and the ladle. The method is used for the casting of copper anodes and permits fully automatic castings by remote control.

Title: Compensating dynamic errors in impulse-bound strap down gyroscopes - is by incorporating analog regulators between gyroscope and modulator
Inventor: LANGE THOMAS DIPL ING
IPC: G01C21/16

Title: Emergency gravity lock for outwards opening windows - has gravity locking rod with locking seat for locking hook
Inventor: HABERL JOSEF
IPC: E05C9/02
Filed: 1973-11-09
Abstract: The gravity emergency lock is used for doors or windows which open outwards. The locks of this kind are used in coastal and mountain areas subject to high winds and storms.

The gravity locking rod has at its upper end a locking bracket which engages with the locking hook. The wedge shaped connection between the hooks and this bracket ensures positive locking. At the lower end is arranged a closing bracket with sloping ribs which makes firm contact with the lower end of the locking rod. This locking arrangement can be used for double panel arrangement and for single panel arrangements.
