Patent FR-2334395-A1 (FR)
Title: Horizontal rotary drum for countercurrent extraction by liq. - from solids, esp. sugar from sliced sugar beet
IPC: C13B10/10
Filed: 1975-12-09
Abstract: Machine comprises a horizontal, cylindrical, rotary drum having twin, internal, helical scrolls. The scrolls form two series of conveying cells which carry the solids axially through the drum, counter-current to the liq. At the solids infeed end of drum, each inter-scroll cell is enlarged with a liq. accumulating chamber formed on the exterior of the drum circumference. Each liq. accumulating chamber is pref. formed as a convex pocket on the outside of the cell with which it communicates via baffles extending into the cell and inclined in the opposite direction to that in which the drum rotates. Liq. is pref. drawn off as its temp. drops below that suitable for extraction and is replaced with hotter liq. The liq. accumulating chambers serve as reservoirs of liq. so that a continuous feed of solids becomes soaked in a completely homogenous fashion immediately on entering the drum. This improves extraction efficiency.

Title: Conveyor system with driven trolley - has running wheels of different diameters, and corresponding guide tracks
IPC: B65G21/22
Filed: 1976-04-13
Abstract: The conveyor system has trolleys, running with wheels on tracks, and driven via a parallel current path. The trolleys have several groups of running wheels (L1, L2) of different diameters. The support tracks (TS) have a group of guide tracks (TS, ZB) corresponding to the number of groups of running wheels. The guide tracks are positioned along the support tracks, so that at any point on the latter, only one group is in contact with the associated group of wheels. At the transfer points between two groups of guide tracks, one group of wheels moves out of contact with its guide tracks, and the wheels of another group engage on their associated tracks. One group of guide tracks may form an integral part of the support track, and extend over its complete length.

Title: Circular loom weft insertion - using radially-adjusted healds to allow weft to be laid in continuous circular path
IPC: D03D33/00
Filed: 1976-09-14
Abstract: The loom is composed of >=2 gps. of operating units arranged in a circular plane so that, in their radial adjustment, they are controlled to move a number of warps alternatively inwards and outwards. The warps are fed to the radially-positioned operating units, while guides rotate in the same direction to control the simultaneous radial movement of the two gps. to position the warps. The weft insertion unit travels continuously in a circular path to lay the weft between the warps, with a weft supply system, and a mechanism to wind the woven fabric. Device is used for the mfr. of linen, velvet, striped or loom knitted materials, foam-type fabrics, etc. with interrupted or continuous yarns. The design allows the advantages of conventional looms to be exploited, while eliminating the noise and variable shuttle speeds when the weft is laid in a reciprocating movement, increasing the rate of weft insertion, using conventional fabric winding beams.

Title: Hot air tunnel to dry fruit esp. plums to make prunes - increases output by using only fresh air with intermittent heating
IPC: A23N12/08
Filed: 1977-04-27
Abstract: The tunnel has an air heater and a blower which directs heated air to an intermediate compartment of the tunnel. Trollies loaded with fruit advance, counter current to hot air, along a tunnel section leading to the intermediate compartment. From the compartment the trollies leave along a second tunnel section, now moving co-current with the hot air. Air blown into the tunnel is now drawn entirely from outside the tunnel without recycling any air exhausted from the tunnel. The air heater is operated intermittently under control of an adjustable cycle timer. The tunnel is used for a drying process in which air is heated to about 100 degrees for introduction to the intermediate compartment. Air at this temp. would rapidly spoil the prod. but is only used for short spells of about 18-20 mins with intervals of 4-5 mins. during which unheated air is blown through the tunnel. Process parametes are pref. selected so that fruits adjacent the intermediate compartment are retained in a temp. range with upper and lower limits =20 degrees apart.

Title: Proximity fuse for explosive projectile - uses micro-cavity, contg. emitter-receptor of radar radiation and circuit detecting radiation received and initiating firing
Inventor: CASTERA ANDRE
IPC: F42C13/04
Filed: 1978-01-09
Abstract: A proximity fuse for a projectile incorporates an open radar micr-cavity machined in the head of the projectile, with an emitter-receptor of radar radiation inside the cavity and an electrical circuit to detect a radiation received and to initiate the firing of the proximity fuse. The emitter-receptor is pref. a GUNN diode to which is applied a direct potential so as to cause it to emit a fixed ultra-high-frequency wave. Applications of the fuse include antivehicle mines, antipersonnel mines, hollow charges, bombs and torpedoes. Existing proximity fuses use antennae, e.g. electrical windings, for the emission and reception of radioelectric waves to detect the doppler effect produced by the wave reflected by a target, necessitating a large vol. in the nose of the projectile. The use of a micro-cavity as proposed by the invention reduces the vol. of the emitter-receptor since it is possible to make cavities of dia. as small as four to five mm.
