Title: Hydraulic fluid controller for tractor - uses increased hydraulic resistance of function to control other functions
IPC: E02F9/22
Filed: 1974-05-22
Abstract: Hydraulic fluids which operate various tools and functions on a tractor vary in pressure die to variations in resistance caused for example by a tool meeting an obstacle. Controllers and valves are connected into the hydraulic circuits. When the pressure of the fluid at one function or tool increases and exceeds a threshold set by a value the fluid acts on the controller. When this same fluid exceeds the threshold set by another valve then the fluid acts on the appropriate controller. This action can be repeated on other controllers. Various combinations of actions on tools and controllers is possible .

Pref. microorganisms is Candida tropicalis.
Patent FR-2243242-A1 (FR)
IPC: H01L21/52
Filed: 1974-09-05
Abstract: A flat surface of a semiconductor chip is soldered to a relatively larger flat surface of a heat sink by forming a plurality of closely spaced grooves in the flat surface of the heat sink, coating the flat surfaces of the chip and the heat sink with nickel, disposing solder between the coated surfaces of the chip and the heat sink, and heating the surfaces until the solder melts. The grooves in the heat sink prevent the entrapment of gas bubbles between the chip and the heat sink, thereby providing good thermal conductivity and a relatively low electrical resistance between the chip and the heat sink.

Title: Optimum temp. detector for frying vat cooking oil - has indicator operated at Curie point temp. of magnetic element
IPC: G01K7/38
Filed: 1975-02-18
Abstract: The optimum temperature of cooking oil in a frying vat is detected by a magnetic element whose Curic point temperature is slightly above the required value, and whose magnetic force acts against a speing. Two elements may be employed to signal upper and lower limits of temperature. The detector comprises a non-magnetic tube (1) closed at the lower end by a permanently magnetic plug (2). A second tube (4) slides inside the outer tube and is sealed at its lower end by magnetic plug (5). A spring (7) acts against the magnetic force of the plugs (2, 5) but has insufficient force at normal temperatures to overcome magnetic attraction. At the Curie point temperature the spring overcomes magnetic attraction to force the inner tube (4) upwards to expose coloured capping (6) as a signal.

Title: Injection mould - ith movable side and top members has automatic degating and sprue removal device
IPC: B29C45/33
Filed: 1975-12-30
Abstract: Injection mould having laterally openable side mould members which define open-ended mould cavity, base member and top closing member with sprue and runner passages. Automatic degating and sprue removal device consists of base mounted core pin which becomes anchored in the solidified sprue. Similar pins become anchored in individual runners. Opening movement of the top member causes the runners to break away at the gates and then pulls sprue and runners from the top member. Used esp. for moulding multiple articles with irregular shaped bottoms. Clean removal of sprue and runners during removal from the mould avoids subsequent manual work. The device avoids difficulty of operating with ejector pins on the irregular shaped bottoms. It is easier to change a machine for moulding different parts.

Title: Slatted curtains drive mechanism - with clear track between main and second secondary drive
IPC: E06B9/304
Filed: 1975-12-29
Abstract: The slatted curtains' drive mechanism incorporates a turning device for swivelling individual slats about their longitudinal axis and a transport medium to displace them across this axis for opening and closing the curtains, using plant gearing. Between the drive (4) and the second secondary drive (7) for the turning device or transport medium there is a clear track corresponding to a prescribed number of revolutions in the first secondary drive (6). This clear track is provided by switching in the planetary gearing (14, 15, 16) between drive and second secondary drive in such a way that a part (17) of the planetary gearing comes into play against a stop (18) at both ends of the clear track. Variations in the first or second secondary drives' braking moment have no effect on the drive moment at the disposal of the latter.
