Title: Process for the processing of thermoplastic polymers by means of the injection-moulding technique
Inventor: AEPPLI ETIENNE
IPC: B29C45/00
Filed: 1994-12-15
Abstract: In the case of liquid crystal polymers, on the one hand the rigid molecule chains and on the other hand possibly present fibrous reinforcing materials are aligned largely parallel to a weld line or flow line, with the result that the physical properties are lacking in the region of the weld line or flow line. It is an object of the invention to provide a possible way of preventing weld lines or flow lines from occurring in the first place. For this purpose, the liquidified material is subjected to a shearing energy from its entry into the injection mould, over at least part of the length of the workpiece. This shearing energy is produced by relative movement between two surfaces of the mould parts. <IMAGE>

Title: Synthesis gas generator with combustion and quench chambers
Inventor: DEEKE WOLFGANG
IPC: C10J3/48
Filed: 1998-04-01
Abstract: The synthesis gas generator incudes combustion and quenching chambers. Gases are formed by partial oxidation in the combustion chamber. These are quenched, cooled and cleaned in the remainder of the unit. In this novel design, separate combustion (3) and quenching (7) chambers are connected by a duct (6). At the gas inlet region of the quench chamber, tuyere-like blast pipes (10, 11) are terminated by quenching nozzles (9). These distribute finely-divided quench medium (8, e.g. water) into the product gas. The quench zone is followed by a gas mixing zone (7a). The quench chamber outlet (20) is conical and discharges over a water bath (21). The gas is returned through 180 degrees just beyond the cone termination, and leaves by the outlet connections (23).

Title: Process for the production of a thermal insulating panel
Inventor: MCLOUGHLIN JAMES ANTHONY
IPC: F16L59/02
Filed: 1994-02-24
Granted: 1997-03-19
Abstract: A thermal insulating panel is manufactured from a substantially rectangular sheet (11) of porous material by folding the sheet over on itself to bring a pair of opposite edges (12, 13) into overlying aligned interfacial engagement with one another and securing the overlying edges together along the interface therebetween to form a tubular member having a seam extending in an axial direction. The tubular member is then flattened to form two opposed closed side edges (15, 16) extending in the axial direction and two lateral opposed open side edges (17, 18), the seam being positioned intermediate the two opposed closed side edges. One of the two open side edges (17) is then closed to form an envelope open along one side edge (18) and particulate thermal insulating material is introduced into the envelope through the open side edge which is then closed. Pressure is applied to the exterior of the envelope to consolidate the insulating material and to form a substantially rectangular panel having two opposed side edges (15, 16) neither of which contains the seam. <IMAGE>

Title: Motorized bicycle with integrated dual traction (muscular and mechanical)
Inventor: PELLEGRINO GIOVANNI
IPC: B62K/
Filed: 1990-08-30
Granted: 1994-11-28
Abstract: Motorized bicycle with integrated dual traction (muscular and mechanical), consisting essentially of a bicycle, preferably a touring or racing bicycle, motorized by a light-duty motor (approx. 0.2 - 0.8 hp) designed to be able to supply a fraction (for example one half) of the entire drive necessary for propulsion, the other fraction being provided by the user via the pedals. The result is a novel and original two-wheeled vehicle allowing the user to make a healthy investment of exercise which, with a moderate physical effort, results in the gratifying motion produced by the sum of the two propulsions, viz. muscle power and mechanical power. There is also, compared with travelling at the same speed on an ordinary moped, great simplicity of construction and hence a cost saving, a halving of the weight and size of the motor, and of its consumption and of the associated harmful emissions. <IMAGE>
