Patent DE-3621016-A1 (DE)
Title: Releasable fastener
Inventor: HESS HERMAN A
IPC: A44C5/20
Filed: 1986-06-23
Abstract: A releasable fastener has a male fastener part (10) with a shank (14) and a T-shaped head (16) with two arms (18, 20), and has a female fastener part (12) which is formed from a long main part (26) with a rear section (28) and a front section (30). The front section (30) is bent in a curve and forms a hook (31) of J-shape in cross-section in such a way that the section (30) ends in an end piece (31a) which is arranged approximately parallel to, but with spacing from, the rear section (28). A long opening (32) passes through the fastener part (12), said opening being sufficiently long to allow an arm (18) of the head (16) to be introduced. The free edge (34) of the end piece (31a) allows the head (16) to be passed completely through the opening (32) in the fastener part (12) only in a particular position. The edge (34) has a recess (36) to receive the head (16) when the fastener part (10) assumes the particular position in order to allow the head (16) to pass completely through the opening (32). Unintentional release of the fastener parts (10, 12) from one another by shaking or impact is extremely unlikely because, for this purpose, the fastener part (10) would firstly have to be released from the depression formed by the hook (31) and then turn into the exact position in which it is congruent with the recess (36) and the opening (32) in the fastener part (12). <IMAGE>
Patent DE-3629609-A1 (DE)
Title: Hydromechanical control of the valve opening times on internal combustion engines
Inventor: KLEINMANN PAUL
IPC: F01L13/00
Filed: 1986-08-30
Abstract: For the optimum utilisation of power, torque, consumption and exhaust gas composition, the timings of the valves must be adjusted according to the speed and load output of the engine. Known solutions are of very expensive design and therefore uneconomic. The invention solves this problem in that from the pressure chamber of the hydraulic clearance adjusting element an oil passage leads to a control element, which allows variable quantities of oil to flow out during opening and closing of the valve. As a result, the adjusting element is compressed, the valve opens later and closes earlier.
Patent DE-3632055-A1 (DE)
Inventor: PLAKSIN EUGEN
IPC: B01D53/24
Filed: 1986-09-20
Abstract: Device for treating the combustion air of jet engines comprising at least one combustion chamber (4). The purpose of the invention is to reduce the percentage of nitrogen contained in the combustion air and reaching the combustion chamber, and to increase the percentage of oxygen. Furthermore, the nitrogen must serve at least partly to cool the turbine, which undergoes high thermal stresses. Guide means (20) are provided in order to impart to the combustion air, before entry into the combustion chamber (4), not only an axial movement but also a rotatory movement around the longitudinal axis (22) of the jet engine. Furthermore, at least one separating element (7) separates the relatively heavy oxygen and/or ozone molecules from the comparatively light nitrogen molecules and conducts the former into the combustion chamber (4), thus causing the nitrogen to be led passed said chamber.

Title: Method and device for piercing open gas cartridges
Inventor: BRIESECK HERBERT
IPC: F17C7/00
Filed: 1986-12-30
Abstract: The invention relates to a device and a method of piercing open gas cartridges. In order to ensure targeted penetration of the piercer into the cartridge wall and to empty the gas cartridge in an operationally safe manner it is proposed, according to the invention, that the gas cartridge be brought up to a piercer located in a cartridge chamber by means of a pressure plate actuable by a hydraulic cylinder, pierced and separated again from the piercer by the pressure plate. The pressure plate has a carrier which can be brought into interlocking connection with the gas cartridge. According to the method, the pressure plate and the cartridge are first brought up to the piercer, and the cartridge wall is then pierced in a quick, abrupt movement. <IMAGE>

Title: Elements for locating, in particular, cylindrical work-pieces in a pallet
Inventor: KRAEMER FRIEDHELM
IPC: B65D19/44
Filed: 1987-01-16
Abstract: In known pallets for storing and transporting cylindrical work-pieces, there are few possibilities of having a variable arrangement of the elements receiving the work-pieces inside the pallet. The solution proposed is intended to provide a multiplicity of possibilities of arranging the elements and is not only to be usable for the storage of work-pieces of different sizes, but also to make the most complete use of the pallet interior for storage. Each of the elements (9) receiving the work-pieces (8) extends over at least two, but preferably over three, beads (3) of the pallet interior and has a length which forms an integral part of the distance between opposite pallet walls (2), said distance being measured transversely to and/or in the longitudinal direction of the beads. Additionally, the element (9) is fitted with tongues (13) and depressions (14) which permit the elements (9) to be connected to one another in a positive-locking manner. Different configurations in the arrangement of the elements (9) inside the pallet are therefore possible. <IMAGE>

Patent DE-3704441-A1 (DE)
Title: Electronic starter for a high-pressure discharge lamp
Inventor: WUERSCHING ISTVAN
IPC: H05B41/18
Filed: 1987-02-12
Abstract: The electronic three-point starter, which is constructed using the strip-mounted system is connected by means of its input to a radio-frequency filter capacitor as well as to a capacitor (which is connected in series with the primary winding of a high-voltage pulse transformer), a resistor and a rectifier diode. The output is formed by the secondary winding of the pulse transformer, while a semiconductor switch (which connects the capacitor to the primary winding of the pulse transformer) is connected in parallel with a series element which consists of the resistor and the diode. The starter according to the invention can be characterised in that the semiconductor switch is a SIDAC (bidirectional diode thyristor) which is connected to a second diode, whose polarity is opposite to that of the first diode, and thus bridges the series element which consists of the resistor and the diode.

Title: Arrangement for feeding stored liquids to an end of a tuft of hair
Inventor: BLANKSCHEIN WERNER
IPC: A46B11/00
Filed: 1987-04-24
Abstract: A tuft of hair preferably made of synthetic hair is contacted partially with the outer side, which is free of holding means, at least temporarily by a storage device filled with liquid, said liquid being conveyed to the tip of the tuft of hair by means of the capillary effect which is produced by matching the surface roughness of the hairs to the viscosity of the liquid. The arrangement according to the invention serves to produce tufts of hair with storage devices, similar to felt-tip pens or eyeliners in plastic containers. <IMAGE>

Patent DE-3724551-A1 (DE)
Title: Process for the preparation of an organic/organic fertiliser
Inventor: HEINZE GERALD DR
IPC: C05F9/00
Filed: 1987-07-24
Abstract: The invention relates to a process for the preparation of an organic/organic fertiliser from organic fibre which is obtained by processing refuse and waste material and admixing farmyard manure. The farmyard manure must be rapidly degradable, for example cattle manure, pig manure, liquid manure and the like. This process allows organic waste materials and excess farmyard manure to be used in a useful manner. The substances can be mixed with each other, or agglomerations can be formed. The result is a composition of slowly degradable organic fibre and rapidly degradable organic fertiliser, and such a composition is of importance for soil fertility. The organic fibre, which is converted in the soil, stores the nutrients incorporated via the different types of manure so that they are kept available for the plants.
