Patent DE-2033844-A1 (DE)
Title: Drill string driving head
IPC: E21B3/04
Filed: 1970-07-08
Abstract: The connector which screws into the end of the drill string, has a spherical head clamped between two shell pieces, the lower one carrying a sleeve onto which a drive pinion is keyed.

Title: Decorative coloured plate prodn - by casting zinc alloys with coloured oxide film formed on the melt surface
IPC: B22D25/02
Filed: 1970-07-23
Abstract: Molten zinc alloy is exposed to an oxidising atmosphere under controlled temp. conditions, for a predetermined time, to form a coloured oxide film on the surface of the melt, which is tehn cast into a flat mould in such a manner that the oxide film is tiered and forms a coloured flow pattern on the surface of the cast plate. Before the solidification, the structure of the cast surface can be influenced by heating, cooling or mechanical movement. Thus, pattern-coloured plates are obtained without any subsequent processing. They can be used for decorative structural application.

Title: Isolating water-insol ammonium polyphosphate - from polyphosphate by washing with ammonia or ammonium salts
Inventor: HECHT HORSTMAR DIPL CHEM DR
IPC: C05B13/06
Filed: 1973-04-02
Abstract: Crystalline, water-insol. ammonium polyphosphates are isolated from their mixts with sol. ammonium phosphates, by dissolving out the water-sol. component of the mixts with aq. ammonia or with aq. solns of ammonium salts (e.g. ammonium ortho-, oligo- or polyphosphates) having a concn. of >1 wt.% (calculated as NH3). The process is pref. carried out on freshly-prepd. ammonium polyphosphate-contg. mixts. Ammonium polyphosphates are used as components of liquid fertilizers.

Patent DE-2337245-A1 (DE)
Title: Heavy load handling servo system - is double acting hydrostatic cylinders with lift rate dependant upon load
Inventor: KUCHARZYK REINHARD
IPC: F15B11/04
Filed: 1973-07-21
Abstract: Apart from the repeatability of the lifting characteristic also non-varying lifting time at varying loads is required. The transport cylinder or the hydromotor-driven lifting rod contains an infinitely variable hydraulic throttle, which works in conjunction with a remotely controlled pressure-independent operation. To change the lifting characteristic it is necessary to change the differential pressure on the hydraulic throttle, changing at the same time the path/throttling characteristic. The change can be carried out by changing the shape of the throttling opening.

The slabs may have bracket flanges on one or both sides underneath. Connection is improved, and production and assembly costs are reduced.
Patent DE-2360961-A1 (DE)
Title: Film transport interlock for cassette camera - has cassette sensor to inhibit transport lock when cassette is removed from camera
Inventor: ZOBEL SIEGFRIED
IPC: G03B17/42
Filed: 1973-12-06
Abstract: The camera as in 2315097 has the film transport operated by sliding the transport lever twice for each frame, with a sensor falling into the frame perforation hole to operate the transport lock, until the frame is exposed. Also a safety catch controls the return movement for the second stroke of the transport lever to provide a different 'feel' for the second stroke. A sensor monitors the position of the cassette and when the latter is removed the safety catch is bypassed to allow normal operation of the lever. This enables the user to repair and check its operation.

Title: Simple effective fume extraction hood for kitchens - incorporates standard water cooling system with thermostatic water supply
Inventor: ABOUSTEIT GEB LUECHT TALEA
IPC: F24C15/20
Filed: 1974-03-26
Abstract: The vapour extraction hood is fitted with a known water cooling system which condenses the greater part of the steam and vapours in the hood which can then be drained off with the cooling water. The supply of cooling water from the water pipe is regulated by a known electromagnetic valve and thermostat to ensure constant effectiveness. The vapours and steam are condensed evenly without the need for expensive filters which need to be replaced. The vapour extraction hood prevents environmental nuisance due to the discharge of clouds of steam contaminated with cooking smells condensing most of the steam and vapours leaves the air relatively pure.

Title: Safety mechanism for land mines - has arming and safety devices feature for recovery of armed mines
Inventor: HELD MANFRED DIPL PHYS DR
IPC: F42C15/44
Filed: 1974-05-16
Abstract: The land mine has a safety device which can be switched into the armed or safe position and vive versa. The safe position is clearly indicated. The mine can be armed on laying and it can be made safe from a distance if, for example, a clear path is required for own troops or for lifting of mines. The mine has a connecting element (16) which accommodates the mine charge detonator initiator. This connecting element acts as a blocking element which can be moved through safety, arming and restored safety position. The latter is indicated by a marking charge (38) which ejects the mine cover plate (8). In this case the main charge initiating cap is also exploded and rendered harmless and hence the marked mine can no longer be exploded by the usual initiating system.
