Patent FR-2307628-A1 (FR)
Title: Horizontal reversing frame for tiles on transfer pallet - has thrust collars on frame shafts for clamping stroke
Inventor: LOTH MANFRED
IPC: B28B11/00
Filed: 1976-04-15
Abstract: A production line for ceramic tiles includes a station where the tiles are turned upside down. This operation is carried out with a hinged frame (1) which is free to swivel about a horizontal axis. Two identical platforms are placed opposite one another inside the frame so that the lower of the platforms receives the incoming tiles on a transfer pallet. A similar pallet is attached to the upper platform. By applying an axial load on two collar plates on the frame shafts, a lever arrangement closes the two platforms until the tiles are trapped between them. The frame is then rotated about 180 deg. and the pallet which now carries the tiles is pushed onto the discharge conveyor by the arrival of a new pallet.
Patent FR-2355537-A1 (FR)
Title: Flash evaporator for e.g. seawater or industrial effluent - has tapering duct to flash nozzles and diverging evaporator duct in each stage
IPC: C02F1/06
Filed: 1976-06-25
Abstract: A flash evaporator comprises a series of evaporator stages, each discharging through one or more flash nozzles into the next stage, the direction of discharge being transverse to the general flow direction. The evaporator comprises two sets of ducts, one set of lateral ducts tapers in its cross-section in the direction of flow towards the end of each evaporator stage, while the other duct or set of ducts increases in cross-section in the same direction. The water discharged from the first set of ducts through the flash nozzles into the second duct and at the downstream of the second duct, the water returns to the first duct of the next stage. A condenser receives and condenses the vapour from the second, diverging set of ducts. Used for any flash evapn. e.g. evapn. of sea water or industrial effluent, where the viscosity may be high. The arrangement ensures that a heavy thick layer of water does not discharge over the weir or nozzle into the evapn. duct, but that a sufficient area is exposed to evapn. to achieve improved thermal efficiency.

The two folding walls of the heads, integral with the base, are fixed to the two bottom lugs (2). Each head wall has at its edge opposite the base lug a top lug forming, with the three other lugs on a strip edge, a frame locked in plane on erecting by nails or hooks.

Where some Mn ore is used, discharge voltage is not so high, but increase in capacity is retained. Electrodes discharged at high current density for prolonged intermittent periods had capacities up to 2400 min.

Title: Multiple action pile driving ram system - has parallel connected rams with phase displacement eliminating ground vibrations
IPC: E02D7/18
Filed: 1977-02-25
Abstract: The multiple action oscillating ram system is used for driving piles or sheet piling. The ram system generates oscillations with different or reversed phases. The arrangement has a number of rams arranged in parallel. The phases can be shifted for driving and for extraction of piles. The parallel connected rams are driven to generate oscillations with different or reversed phases. The oscillations transmitted through the ground between columns or sheet piling wall elements are mutually eliminated which considerably reduces the area over which oscillations are transmitted. The ram assemblies with drives and oscillation generators are suspended by springs on a frame.

Title: Polarisation converter for amplified laser beam - for plasma containment, has two converters with different opposite proportionality factors
IPC: H01S3/00
Filed: 1977-12-28
Abstract: A generator for containing, electromagnetic waves, i.e. light, or infra-red waves, comprises a source and one or more wave amplifiers. The wave amplifier comprises a polarisation converter for causing the wave to propagate with a type of circular polarisation and with negative, azimuthal phase displacement. This plarisation converted consists of: a first converter which receives the linearly polarised wave of type TMo, and converts it to a wave with positive, azimuthal phase displacement by displacing its phase with a first, predetermined proportionality factor in a given first direction proportional to its azimuth, and a second polarisation converter, which displaces the phase of this wave with a positive, azimuthal phase displacement with a second proportionality factor equal to twice the first factor and in the opposite direction, so as to produce a wave with negative, azimuthal phase displacement; and also means for converting the wave with positive or with negative azimuthal phase displacement into a wave with circular polarisation.
