Patent DE-4337569-A1 (DE)
Inventor: WEBER HANS G
IPC: C08G18/66
Filed: 1993-11-04
Abstract: A process for the production of cellular polyurethane mouldings having a compact surface without using CFCs by reacting starting materials known per se which react to give polyurethane foams in closed moulds, using, as a blowing agent, carbamates obtainable from aliphatic amino alcohols and carbon dioxide, optionally in addition to further blowing agents. The process is particularly suitable for the production of foam sheathing of steering wheels, spoilers and of protective cushions in the passenger compartment of automobiles or for the production of shoe soles or shoe components.

Abstract: PCT No. PCT/EP94/04090 Sec. 371 Date Apr. 23, 1996 Sec. 102(e) Date Apr. 23, 1996 PCT Filed Dec. 9, 1994 PCT Pub. No. WO95/17292 PCT Pub. Date Jun. 29, 1995A mould closing device for an injection moulding machine includes a fixed (1) and a movable (4) mould clamping plate for support of screw drives (36) which are freely rotatable in the fixed mould clamping plate (1) and axially supported in one direction and supported in spindle nuts (39) secured in the movable mould clamping plate (4). Provided for actuation of the screw drives (36) for the closing and opening stroke of the movable mould clamping plate (4) are a rotary drive (44) and a hydraulic piston-cylinder unit (45, 46) interacting with the screw drives for effecting the closing force build-up. To ensure a dimensioning of the actuating drive of the screw drives substantially in accordance with the requirements for rapid opening and closing motions while the hydraulic piston-cylinder unit maintains a high closing pressure, it is proposed to form the hydraulic piston-cylinder unit of one or more pistons and hydraulic cylinders, with the admission of pressure medium for effecting the closing pressure build-up being effected by piston-cylinder units which are driven by the screw drives via interposed pressure transmitting devices (19).

Title: Planting aid for inserting planting material into the earth
Inventor: GEIGER ALBERT
IPC: A01G9/02
Filed: 1994-01-26
Abstract: The planting aid consists of a hollow planting container, which has a rigid wall and a pointed end portion which is intended for receiving a flower bulb or a small plant. The planting container is driven into the earth with the foot or with a knocking tool, whereupon the flower bulb is introduced into the planting container. The flower bulb is thereby inserted into the earth at the depth predetermined by the length of the planting container. Located in the wall of the planting container are holes, through which the excess pouring water or rainwater can flow off and pass through the developing roots. The planting container preferably consists of an NWR-based plastic which decays in damp earth and with which a fertiliser, gradually released in small doses during decay, is admixed before processing to form a planting container.

Patent DE-4418195-A1 (DE)
Title: Forced draught sifter with tangential coarse particle outlet
Inventor: NIED ROLAND DR ING
IPC: B07B7/083
Filed: 1994-05-25
Abstract: The sifter comprises a vaned sifting wheel (14) surrounded by a concentric array of variable guide vanes (11) which divide the annular space between the wheel and the spiral housing into outer and inner (9a) zones. Goods to be sifted (3) enter the inner zone and are forced by gas (5) to the outer zone. Coarse particles exit through a tube (8) located at the end of the spiral and between the wheel and variable guide vanes, with longitudinal axis tangential to the centre line of the gas stream. The last guide vane (12a) adjacent to the tube inlet end is adjustable to control the effective exit area. A fixed wall (19) bridges the gap between the tube end and the first guide vane (12b) to prevent incoming goods passing directly to the coarse particle outlet without being sifted.
