Patent DE-4216191-A1 (DE)
Title: Coating machine for coating long lengths of material - has coating device to apply hot melt adhesive e.g. ethylene@]-vinyl] acetate to material, with adhesive chamber, coating roller and coating control means
Inventor: MILLER RAINER
IPC: B05C5/04
Filed: 1992-05-15
Abstract: A machine has a coating device to apply a hot melt adhesive to the material; with (a) a chamber for the adhesive; (b) a coating roller fed from the chamber, and (c) a means of controlling the coating and hence the coating thickness. The coating system has arrangements so that different hot melt adhesives can be selectively fed to the chamber. The machine pref. has a supply of one adhesive based on ethylene-vinyl-acetate and another based on polyurethane. The coating device (30) has an open side (33) towards the work to be coated and a vent (35) in its top. It (30) holds a vertical baffle (42) which can close off the interior as it turns about a vertical axis (45). This divides the interior between a front hot melt chamber (50) and a rear chamber (51) which is part of a feed for ethylene-vinylacetate adhesive fed in through the opening (37). The front chamber (50) has a feed bore (38) for polyurethane-based adhesive; this is within the range of the revolving baffle (44) which therefore can close it off. A coating roller (53) is located in front of the open side (33) so as to leave a gap (47). As the roller (53) revolves it draws adhesive out, and a horizontal rod (54) runs parallel to the roller (53) at an adjustable distance away, so as to control the thickness of adhesive on the coating roller (53).

Also claimed are enantiomer pure cpds. (I), excluding (2S,3S,5R)-2-hexyl-3-benzoyloxy-5-undecyl-delta-valerolactone, (2S,3S,5R)-2-hexyl-2-acyloxy-5-undecyl-delta-valerolactone is also claimed. USE/ADVANTAGE - (I) are intermediates in the prepn. of pharmaceutically active oxetanones, e.g. enantiomer pure (2S,3S,5R)-2-hexyl-3-hydroxy-5-undecyl valerolactone (Ia) can be used in the prepn. of N-(vinyl-L-leucine (S)-1-(((2S,3S)-3-hexyl-4-oxo-oxetan-2-yl) methyl) dodecyl ester, known as a lipase inhibitor with the trivial name tetrahydrolipstatin (THL). The enantiomer sepn. is rapid and highly selective and occurs at an early stage of the oxetanone synthesis. The conventionally used, poor yield step of cyclisation to pyran is avoided.

Title: Axial piston swash plate compressor for vehicle - uses valve control to convey residual gas at high and at low pressures
Inventor: KIMURA KAZUYA
IPC: F04B39/10
Filed: 1993-10-02
Abstract: The swash plate compressor for air conditioning has a valve (76, 78, 90) with the aid of which residual gas can be conveyed from one cylinder bore at the end of a compression stroke to another cylinder bore (20A to 20F) during a given short time interval after the end of the suction stroke in the bore concerned. The valve is so formed that apart of the residual gas having a high pressure can be led to a cylinder bore in which the compression stroke is being carried out. In addition part of the gas having a low pressure can be led to a cylinder bore where the compression stroke is just starting. ADVANTAGE - Allows the suction volume attainable in practice to be raised close to the theoretical volume.

Title: Device having a carrying rod for conveying products in transport containers, such as lorries
Inventor: BERNS HARALD PROF DIPL ING
IPC: B65D90/00
Filed: 1993-10-27
Abstract: The device comprises a carrying rod having two connection heads at the two rod ends in order thus to be coupled to opposite side walls of a transport container, such as the structure of a lorry. Such a connection head is generally structured in three axial sections of different profiles. A central section serves to support the head in the body of the hole. One end section is provided with a radially projecting lug which is intended to engage behind the hole when coupled. Finally, a starting section serves to attach the connection head to the carrying rod. In order to obtain an easily operable and reliable coupling engagement, it is proposed to provide the connection head with a transversely displaceable latching part in which the radial lug of the end section is integrated. This latching part can then be displaced between two end positions, namely a locking position providing a reliable coupling engagement on the one hand and a release position which facilitates the coupling operation on the other hand.

Title: Procedure for three-level controller for e.g. rudder machine
Inventor: LESZKE HANS-H
IPC: G05B19/416
Filed: 1993-12-09
Abstract: In the procedure for adjustments of a mechanical system, the positions and the overrun of the mechanical system are measured and stored at specific intervals by a suitable sensor (21) and are taken into account in the generation of the next adjustment signal so that the controller has an adaptive behaviour.The overrun of the mechanical system is measured separately for two directions. The values determined are stored in a data memory and separately taken into account in the generation of the next adjustment signal.An error integrator additionally adds up the remaining residual errors and the added-up error is taken into account in the generation of the next adjustment signal(s). The error integrator is reset by signal (RESET signal) and the summation process is stopped as long as an adjustment signal is active. The time constant of the summation process is changed as a function of other signals and operational sequences, with the influences specified either acting singly or in combination on the integrator.

Title: Safety pressure valve for container
Inventor: TEICHMANN RALF DR ING
IPC: F16K17/196
Filed: 1994-03-14
Abstract: The safety valve has a main valve element (52) which is pressed against a valve seat by a main spring (82) from the inside of the container. The centre of the main valve element has a cutout with an outwards facing valve seat (64) and has a secondary valve element (72) pulled down onto the valve seat by a tensile shaft (88) between this valve element and the bottom of the valve housing. A second valve spring (96) is braced between the bottom of the valve housing and a thrust element (100) under the main valve element. The main valve opens under negative pressure inside the container and the secondary valve element opens under positive pressure. As soon as either valve element is lifted, by either excess positive- or excess negative pressure, the air flow through the valve opens it further to provide a rapid correction of the pressure. The two valve elements and valve springs are coaxial in a compact mounting.
