Title: Method and machine for joining veneer strips
Inventor: RIESMEIER WILHELM
IPC: B27D1/10
Filed: 1981-05-25
Abstract: Veneer edge strips (of wood) are joined endlessly for mechanical processing. Instead of a finger jointing of the individual veneer strips at their longitudinal ends in order to bond the strips together over an equal area and the subsequent need to make a mark in order to trace the junction points, which are cut out again in the subsequent processing of the endlessly produced veneer-strip ribbon, an overlapping junction of the veneer strips is now provided, the thickened overlapping point itself forming the mark. The veneer strips are joined together in a single operation on a corresponding machine, said veneer strips being passed through a conveying apparatus, a gluing apparatus and a pressing apparatus, and the conveying speeds of these apparatuses being so controlled that the rear strip in each case overtakes the front strip between the gluing apparatus and the pressing apparatus by the overlapping extent.

Title: Level-warning device
Inventor: KUHN MICHAEL
IPC: G01F23/00
Filed: 1981-07-04
Abstract: The invention relates to a level-warning device for a liquid container which can be sealed by a closure and is pressurised during operation. In particular, the liquid container can be a radiator or compensation container of the radiator of a motor vehicle. The level-warning device has a level switch (5) by means of which an alarm can be switched on when the liquid drops below a specific level. In order to indicate the lack of fluid in a level-warning device of this kind until the said lack is eliminated, an electrical fault signal can be fed to a memory unit by the level switch (5) when the level drops below a specific value, and can be stored by the said memory unit. Furthermore, an electrical clear signal which clears the fault signal can be fed in the event of the pressure of the liquid container being relieved, to the memory unit from a pressure switch (8) which can be switched by the pressure in the liquid container. In this process, the alarm is switched on by the memory unit in the case of a stored fault signal. <IMAGE>

Title: Device for wort boiling
Inventor: KOREK JOHANNES DIPL ING
IPC: C12C7/22
Filed: 1981-09-26
Abstract: A device for wort boiling has a wort preheater which is heated by exit vapour and which is located upstream of the boiling and steaming in a brew pan or of a pressure and temperature increase and subsequent let-down of the wort within defined residence times. Downstream of the boiling process, two or more evaporation stages are provided in series, in which an evaporation of the wort right into vacuum takes place. The heat arising during the condensation in the vapour condensers of the individual evaporation stages is transferred to brewing water as coolant, in the direction opposite to that of the wort evaporation, and the brewing water is at the same time heated. The equipment for wort-boiling has at least one sludge separation (20) which is located immediately upstream of the stage (82) at the highest pressure and highest temperature of the stage evaporator (82, 86) for the evaporation of the wort or immediately downstream of the stage (86) thereof at the lowest pressure and lowest temperature and at the same time upstream of the wort cooling (90). <IMAGE>

Title: Insulating slab for outer walls or buildings
Inventor: JABS WERNER
IPC: E04B1/76
Filed: 1982-01-05
Abstract: The invention relates to an insulating slab (1) for outer walls of buildings, which possesses a profile on its outer surface in order to apply finishing coat plasters (3) of low elasticity. This profile in the form of raised ribs (2, 2a, 10) extending diagonally to the horizontal and vertical edges of the insulating slab (1) produces, due to natural temperature fluctuations, above the ridges (4) of the ribs (2, 2a, 10), predetermined fracture points in the form of virtually invisible hairline cracks, and thus diamond-shaped areas (8), in the finishing coat plaster (3). By dividing the finishing coat plaster (3) up into relatively small diamond areas (8), only a very small expansion in the finishing coat plaster (3) in relation to the individual diamond area results, even in the case of large temperature differences. <IMAGE>
