Patent EP-0291715-A1 (EP)
Inventor: LAPEYRE JAMES M
IPC: B65G33/32
Filed: 1988-04-21
Abstract: Screw conveyor apparatus fabricated from integrally molded plastic modules (10A, 10B, 10C) is disclosed. The apparatus includes a multiplicity of modules axially aligned and joined or bonded so as to provide a unitary plastic screw conveyor of a desired length. A plastic axial member (12A, 12B, 12C) extending the length of the screw conveyor and which defines an elongated aperture (18A, 18B, 18C) of a non-circular cross-section is formed by joining or bonding the individual modules. In addition, each of the modules include a flight member (14A, 14B, 14C) which individually helically encircle not more than 360°, but when bonded together result in an overall flight member encircling more than 360° and which extends the length of the joined or bonded modules. The plastic screw conveyor is driven by a drive shaft (28) which has a non-circular cross-section and which is inserted through and cooperates with the non-circular aperture extending the length of the joined axial members. A drive or power source (34) is connected to the drive shaft for rotating the apparatus.

IPC: F42C17/04

Abstract: A device for determining the roll angle of a missile (10) launched from a tube (20), by means of a first magnetic-field sensor (11) located in or on the missile (10), is described. In known devices of this type, the sensor signal is dependent not only on the roll angle, but also on the flight direction of the missile (10). To obtain a definite angular relation between the missile and the phase of the sensor signal in any flight direction, it is proposed that the missile (10) should have a second magnetic-field sensor (12) located at a predetermined distance in the flight direction. In addition, a reference magnet (21) is provided on the tube (20), so that, when the missile flies past the reference magnet (21), the second magnetic-field sensor (12) generates a reference signal determining the instantaneous angular position of the missile (10). The roll angle can then be determined at any moment from this angular position by means of the detected speed of the projectile. <IMAGE>

Abstract: A cartridge for a mechanical pencil has a tubular body (2) wherein pencil leads are contained. Upon insertion of one end of the cartridge in a complementary passage (77) of a lead guide (7), a cylindrical axial projection (71) is received into a hole (107a) provided in a capping structure (10) of resiliently deformable material which closes the end of the cartridge. The end of the projection (71) is received and engages a membrane-like tongue part provided with a central passage 11. When relaxed, the passage 11 is of a diameter too small to allow for the transfer of leads. Engagement with the projection stresses the tongue part to expand the passage 11 and allow the lead to be transferred singly from the cartridge to the lead guide (7) for use. The capping structure (10) is received within the end of the cartridge body (2) and is provided with a circumferential flange (103) which engages the rim of the cartridge body (2).

Abstract: Orthopedic supports (10, 36, 42, 46) are made from a flexible, resilient composite material (12) which includes a base layer (28) of a flexible, closed cell elastomeric material such as neoprene rubber in thin sheet form, with a multiplicity of relatively large air holes (30) extending through the depth of the sheet and dispersed across the surface of the sheet. A skin-­protecting first layer (32) of a soft, flexible, stretchable porous knitted fabric is adhered to a first face of the base layer (28). A protective second layer (34) of a flexible, stretchable porous knitted fabric is adhered to the second face of the base layer (28). The composite material (12) is porous to air and water passing through the depth of the composite layer. Orthopedic supports (10, 36, 42, 46) made from the material (12) are sufficiently elastic to provide compression around a body part supported by the composite material (12) in its stretched condition. The composite material (12) is sufficiently porous to ventilate the supported body part during use such that elasticity and support is provided while heat discomfort and perspiration are prevented. Another embodiment includes a prosthetic stocking (62) made from the composite material (64) which is porous to fluids to provide air circulation during use to avoid heat discomfort.

Title: Discharge nozzle for a gas cigarette lighter
Inventor: EUN UN KEE
IPC: F23Q2/16
Filed: 1988-03-23
Abstract: A discharge nozzle for a gas cigarette lighter comprises an outer sleeve (1) defining a gas flow passage (6) and a coaxial gas ejecting passage (8). Received within the gas ejecting passage (8) is a gas dispersing element (9) which has an inner central smooth bore (10) and an outer threaded surface (11). Both the inner passage, constituted by the bore (10) and the outer passage (12), defined by the threaded surface (11) of the gas dispersing element (9) and the inner surface of the sleeve communicate with the gas flow passage (6). When gas is discharged from the nozzle a proportion of the gas flows around the outer passage (12) and is induced to describe a spiralling motion such that as it exits the gas is dispersed outwardly into the vicinity of a spark created by a piezo-electric sparking device. At the same time the remainder of the gas is discharged through the inner passage. The gas is ignited more easily as the outwardly moving gas reaches the vicinity of the spark and the central jet maintains a stable flame once ignition has occurred.

Abstract: The pump operates using an electromagnetically vibrated armature (26) with a central through-conduit (4) and passive valves (5,6,). The armature has a narrower extension (32) to operate the valves, through which the conduit also passes. 
     In order to avoid fluid building up between the armature and its guide (13), and impeding the movements of the armature, at least one of these is irregularly shaped, to provide firstly longitudinal through paths for such fluid to be quickly scavenged and removed, and secondly, cooperating guiding surfaces which are bypassed by the fluid, and not subject to fluid build-up between them. 
     Therefore, power losses through fluid build ups is avoided, without necessity for state of the art radial drilling of the armature (13).

Abstract: This invention relates to a process for preparing 2,2-bis(4-hydroxyphenyl)propane, e.g. bisphenol A and particularly to a process for preparing high quality bisphenol A with good workability by distilling the intermediate adduct of bisphenol A and phenol. 
     The adduct of bisphenol A and phenol is fed to a distillation column. Phenol is recovered from the top of the column and bisphenol A is obtained from its bottom. In this distillation process, the adduct of bisphenol A and phenol is added with a part of recycled bottom liquid. Consequently troubles such as plugging of the distillation column are prevented, continuous operation becomes possible for a long period of time and high quality bisphenol A can be steadily obtained.
