Patent FR-2470534-A1 (FR)
Title: Machinery for releasing and trimming moulded cream cheeses - by automatically disengaging a floating ram and an open-topped mould
Inventor: LAIGNEAU PIERRE JACQUES JEAN
IPC: A01J25/12
Filed: 1979-11-30
Abstract: A machine for extracting and trimming moulded creamed cheeses prepared in open-topped moulds and compressed by a floating flanged ram has two complementary parts. In the first part, the moulds are loaded sequentially on to a conveyor above which pairs of rails engage the upper flange of the ram to rock the fam from side to side, breaking contact with the cheese surface, before lifting the ram clear of the mould while the latter held down by ancillary rails. The moulds are automatically transferred to the second part of the machine where reciprocating suckers lift the cheese out of the moulds and support the cheeses while a residual meniscus is trimmed off by a rotary knife. The trimmings are removed by a conveyor having gaps through which the suckers can reach down to the moulds and raise the cheeses before the conveyor surface steps into position to collect the parings. Reduces the amount of manual work traditionally involved in preparing Saint Paulin or similar cheeses moulded in a cloth cover. Removes the residual meniscus generated at the mould/ram interface.

Title: Magnet assisted snap switch - has contact pin controlled by springs biased towards its end position and thus requires less force for its actuation
IPC: H01H5/02
Filed: 1980-04-18
Abstract: The shorter path of the snap switch limits the gap to under 1 mm and reduces the cost by simplifying the design and results in a unit requiring less force for its actuation. The contact pressure is enhanced by the spring bias in the direction of the final position of the moving contact. The bias at the mid position of unstable dead point ensures the improved operating characteristic of the switch. THe housing (10) guides the switching pin (12) exhibiting recess (14) for the contact bridge (16) biased by a spring (22). Two additional leaf springs (28) engage a groove of the contact pin which carries a magnetically permeable plate (32) with bolts (34) passing through holes of the housing where a permanent magnet (36) is screened by casing (38).

Patent FR-2483047-A1 (FR)
Inventor: HANTELMANN HARALD
IPC: C02F1/04
Filed: 1981-05-19
Abstract: In the case of the method for extracting heat from an aqueous base medium by means of expansion of the latter, expansion is carried out in steps in a number of expansion steps which are arranged one behind the other with respect to the medium flow. The vapour extracted in each expansion step is drawn off from the step and the individual quantities of vapour are subjected in each case to thermal utilisation and/or enhancement measures parallel to one another. In one embodiment, the base medium takes the form of water fed through a boiler, which water is circulated via a heat pick-up point and through the expansion steps. The vapour extracted is subjected to thermal compression and is fed to a common vapour rail. The heat pick-up point and the heat exchangers (35, 36 and 37) are heated by a waste-heat source (39). One product of this method is pure water vapour.
