Title: Automatic release for life-raft - has water pressure operated catch to release mooring line
Inventor: WILDHAGEN BIRGITT INGEBORG
IPC: B63C9/22
Filed: 1977-02-28
Abstract: The liferaft is secured on the ship by a strap which is opened by the self inflating action, after manual release. The inflated liferaft is then moored to the ship by a securing line linked to a safety catch (4, 6), which is held in the deck mounting by a release catch (31). This is moved aside by a water pressure switch as the ship sinks to release the raft. A manual overide releases the line before the ship sinks. If the ship sinks with the raft not inflated then the automatic release operates to release the raft as well as to open the self inflating mechanism.

Title: Metal powder prodn. - by atomising molten metal stream through pressurised agent jets and collecting droplets in reducing fluid
Inventor: LARSON ULF RUTGER
IPC: B22F9/08
Filed: 1977-07-21
Abstract: Metal powder is produced in an enclosed granulation chamber with a reducing liquid in the lower part and a reducing gas atmosphere filling the upper part. Metal is poured in the molten state and intersected by streams of pressurised atomising agents. The metal particles are chilled in the gas atmosphere and collected in the reducing liquid. This enables a fine-grained product to be produced which has an extremely low oxygen content. The process is much cheaper than one using nitrogen or argon for the atomisation.

Title: Grid construction sight screen - has grid bars with special height, depth, width ratio, spaced apart and off set
Inventor: MAURICH ROLF VON
IPC: A47G5/00
Filed: 1978-05-12
Abstract: The sight screen (10) is formed from two grid plates (11, 12) mounted spaced one behind the other. The grid bars (12) in plan view are twice as deep (t ) as their height and width. Although no more expensive to manufacture they provide a better screen so that it is not possible to see through to the other side. The grid bars of the two plates are preferably offset relative to each other further increasing the screen protection. A clear disc (14) or plate can be detachably slid in between the two plates to serve as a wind shield.

Title: Indicator showing saturation of filter in extractor hoods - operates without maintenance, manual control but according to pressure differentials
Inventor: WACHENFELD ADOLF
IPC: F24C15/20
Filed: 1978-06-22
Abstract: The extractor hood contains an underpressure chamber (3) located behind the fat filter (2) and a ventilator (6) which feeds the air from this chamber to an excess pressure chamber (4). Here, the pressure arising in the underpressure chamber between the non-saturated and saturated filter serves as the value for actuating the sound indicator mechanism (7) which shows when the filter is saturated. This indicator is immediately ready for use once the filter is changed and requires no maintenance. It preferably has a channel housing connected with the excess pressure chamber.

Title: Valve push rod for IC engine - is steel tube welded to case hardened end piece which has flat proximal and curved distal surfaces
Inventor: USUI MASAYOSHI
IPC: F01L1/14
Filed: 1978-09-30
Abstract: The valve push-rod for an IC engine if formed by electric resistance welding a case-hardened end piece (2) on the end of a steel tube (1) and controlling the rate of cooling following cessation of the welding current. This may be effected by heating the weld zone so as to form a transition layer comprising a mixed alpha-martensite and primary troostite structure. This bridges the annular weld zone boundary around the tube wall in the region of the end of its base. The heating current is applied simultaneously with cessation of the welding current.

Title: Milk flow stabilisation procedure - involves introducing air into part flows from teat cups depending on milk volume
Inventor: HAMANN JOERN DR
IPC: A01J5/04
Filed: 1978-11-13
Abstract: The milk flow stabilisation procedure is for a milking machine operating with an alternating suction and discharge phase. The part flows leaving the individual teat cups are brought together to form a complete flow and the complete flow of milk is taken away via a milk-passing system. The part flows (29, 31) are aligned in the direction of the leaving total flow before they are brought together in a conical receptacle (5). Air is introduced into the flows towards the total flow. The volume of air depends on the total volume of the extracted milk and on the vacuum level.

Title: Bank cash handling machine powered by electric motor - allows coins or notes of different denominations to be packaged into predetermined amounts using potentiometer adjustment
Inventor: FURUYA KATASUKE
IPC: G07D9/06
Filed: 1978-12-02
Abstract: The cash handling system is for coins or banknotes and is designed to accommodate a large range of denominations and currencies. The system is based upon a number of different controlled positions of an indexing selector. The system avoids the use of cam mechanisms by using a potentiometer based positioning system. The drive motor (17) of the system is controlled by signals transmitted to a drive stage (16) from a control circuit (15). A pair of potentiometers (11, 13) provide a difference signal to control the direction and position of the motor coupled load. One potentiometer (11) is used to set the reqd. position relating to a specific denomination. The motor moves the load table until the coupled potentiometer (13) produces a volt. signal to reduce the difference to zero.
