Patent DE-3639233-A1 (DE)
Inventor: TORBUS MAREK DIPL CHEM DR
IPC: B22C1/20
Filed: 1986-11-20
Abstract: PCT No. PCT/EP87/00691 Sec. 371 Date Jul. 13, 1988 Sec. 102(e) Date Jul. 13, 1988 PCT Filed Nov. 7, 1987 PCT Pub. No. WO88/03847 PCT Pub. Date Jun. 2, 1988.The binder serves to produce foundry moulds and comprises a solution (preferably an aqueous solution) of aldehyde reactive phenol substances and gaseous acetals (preferably dimethyl formal) as reaction partners and strong acids, e.g. sulphuric acid and sulphonic acids as a catalyst. The acetal is in this system hydrolysed by the acid, the basic aldehyde being formed, which will react with the aldehyde reactive phenol substance accompanied by cross-linking. The acid serves thereby simultaneously as a cross-linking catalyst. In principle, it is possible to regard as "aldehyde reactive phenol substances" any phenolic compounds which can in the acid range cross-link more or less spontaneously with aldehydes. Preferably, these are resorcinol or resorcinol products, e.g. resorcinol pitch or precondensates formed with a shortfall of aldehyde, e.g. based on resorcinol formaldehyde, phenol resorcinol formaldehyde or resorcinol melamine formaldehyde. To produce foundry moulds, a granular basic moulding material, e.g. sand, the solution of the aldehyde reactive phenol substance and the acid are used to produce a moulding mixture which is then caused to set by passing the gaseous acetal (formal) through it. The aldehyde cross-linking of the aldehyde raective phenol substance in the acid medium, the process which takes place thereby, produces duroplasts (resites), which combine a very good thermal resistance and a low pollutants emission during casting with a high strength and negligible sensitivity to moisture in the mouldings produced, features which make them extremely favorable.

Title: Pipeline, in particular of a vacuum cleaner
Inventor: APPEL WOLFGANG
IPC: F16L37/138
Filed: 1986-11-28
Abstract: The invention relates to a pipeline, in particular of a vacuum cleaner, having two pipe portions which overlap in the axial direction and are releasably fastened to one another in a manner appropriate for operation. In this arrangement, the pipe connection is to be configured such that it can be released more easily. In order to achieve this object, the invention proposes that the pipe portions (2, 4) have approximately the same cross-sections and butt against one another along an endless parting line (14). The said parting line (14) extends in the axial direction over the entire length of the overlap and, seen in an axis-parallel direction, exhibits an undercut, i.e. it intersects an axis-parallel surface line of the pipeline three times, and a connecting sleeve (40) coaxial with the pipe portions (2, 4) is guided on the pipe portions (2, 4) such that it can be displaced in the axial direction between an open position on one pipe portion (2) and a closed position engaging over the two pipe portions. <IMAGE>

Patent DE-3714858-A1 (DE)
Title: Gearing for small wind and water power plants
Inventor: SCHOPF WALTER
IPC: F03D9/25
Filed: 1987-05-05
Abstract: The object of the invention serves for more efficient acquisition and conversion of renewable forms of energy, such as wind and water power, into electricity, in particular for supplying independent supply districts (isolated operation) and for minimising plant costs.   The gear train as designed in the invention divides the power path coming from the prime mover into two power paths for two separate supply systems:   - a power path with automatic speed control for driving a small a.c. generator, for priority supply of a base-load system with clean, constant-frequency current; - and a power path for driving a larger generator without automatic speed control for converting the energy arising that exceeds the base demand, for example for heating, producing hydrogen electrolytically, or for other forms of storage.   Apart from the advantage of low losses, and thus efficient energy conversion, when only small amounts of energy are available, the construction effort and costs of the supply path with automatic speed control can be kept modest, and the components for converting sporadically occurring excess amounts of energy can be constructed in a robust, inexpensive and reliable manner.

Title: Hydraulic compensating element for inlet/exhaust valves of internal combustion engines
Inventor: RONNIGER CURT-ULLRICH
IPC: F01L13/00
Filed: 1987-06-02
Abstract: Provided in a hydraulic valve-clearance compensating element there is a restrictor passage via which a greater or lesser quantity of hydraulic medium is pumped out of a hydraulic chamber into a storage chamber as a function of the speed of the internal combustion engine. Thus, depending on the engine speed, only a somewhat reduced stroke is imparted to the valve by the cam. For the refilling of the hydraulic chamber, a separate filling passage provided with a non-return valve is provided and the enlargement of the hydraulic chamber takes place by means of a spiral spring provided between the tappets forming the chamber. Each compensating element for the simultaneous influencing of the valve stroke transmitted is optimised as regards efficiency and functional reliability.

Title: Means for securing against opening a tensioning lever with bare hands
IPC: E05C19/14
Filed: 1988-03-11
Abstract: According to VDE 160, clause 4.5.1.c, the opening of the covering of a housing with inbuilt electrical operating means is possible only by a tool, for example a screwdriver. When using tensioning levers (SH) as a quick-acting closure for fastening the covering, additional arresting means, such as screws, split-pins or locks, are known. However, these have to be mounted in a separate procedure when closing the covering. According to the invention, a securing plate (SB), composed of two flaps (L) covering the lateral engagement surfaces (AF) of the closed tensioning lever (SH) and spaced apart by a distance corresponding to the width of said tensioning lever (SH) and of a covering lug (AL) between the flaps (L), is arranged in front of the end of the closed tensioning lever (SH), as an adapted sheathing around the tensioning lever (SH). Said tensioning lever (SH) can thus be closed by finger pressure, but the flaps (L) and the covering lug (AL) prevent firm access to the side surfaces of the lever, which is subjected to spring stressing. Opening can only now take place by the insertion of a screwdriver into a gap between the tensioning lever (SH) and the flaps (L) and/or the covering lugs (AL). <IMAGE>

Title: Reciprocating piston internal combustion engine with piston cell
Inventor: DOLHAY ZSOLT
IPC: F01L3/06
Filed: 1988-08-10
Abstract: The fact that combustion in a confined space cannot be concentrated over the ideal period using the known solutions constitutes a general problem. For this reason the pressure and the temperature cannot be kept sufficiently high without the risk of excessive mechanical stressing. We are frequently unable to ensure sufficient swirling of the new air charge or the mixture. The object of the invention therefore is to put forward a solution to both these problems, thereby increasing the top speed and maximum power output of diesel engines. A reciprocating piston internal combustion engine with piston cell according to the present invention is characterised in that the valve seat ring block which lifts off from the cylinder head after the piston fills the upper part of the piston cell in the vicinity of the top dead centre of the piston.
