Title: Process and apparatus for the formation and processing of a stack of blanks
Inventor: RUEDIGER FRIEDRICH
IPC: B65H45/101
Filed: 1982-11-22
Abstract: A process and an apparatus for the formation and processing of a stack of textile blanks relate particularly to the production of bed linen. In this, the economic outlay in the work phases preceding the sewing process is reduced in that the number of necessary working operations between the completed finishing of the textile web and the sewing process is decreased and use is made of an apparatus according to the invention, in which cutting is carried out simultaneously during the folding operation to form a vertical pile. For this, the folding blade is equipped with a respective edge groove and two horizontal band knives are arranged. A vertical pile of unfolded or prefolded blank parts is obtained. The blank is thus introduced for the first time into the preliminary-stage operation and already prefabricated blank parts are transported to the various end-product operations and completed there. <IMAGE>

Patent DE-3306632-A1 (DE)
Title: Wire-lining mat with fine-meshed net
Inventor: GIERKE HEINRICH R
IPC: E21D11/15
Filed: 1983-02-25
Abstract: Wire-lining mats for use underground consist of longitudinal and transverse bars crossing one another in a coarse mesh, the longitudinal bars being bent to form hooks. This supporting framework is assigned, on the transverse bar side, a textile fabric which is expediently designed to be longer than the mat itself on one side and in the mat longitudinal direction. The textile fabric is in each case joined to the adjacent lining mats by means of this excess length or the overlap in the mat longitudinal direction, so that a continuously sealed closure is produced. This sealed closure is advantageously also possible without the mats having to be fitted in overlapping manner. They can, in fact, be fitted mutually abutting and thus without great outlay by subsequently joining the overlapping or protruding parts of the textile fabric to one another, for example by means of a velcro strip fastener. <IMAGE>

Title: Method for measuring the edges of a piece of timber undergoing longitudinal transport, and device herefor
IPC: G01B11/04
Filed: 1983-05-11
Abstract: A method for measuring the edges of a piece of timber undergoing longitudinal transport and a device herefor are specified, in which the top side of a piece of timber is separately illuminated for in each case one pair of edges from edges situated diagonally on the piece of timber, and from this an image is produced in which the edges appear as contrast lines between light and dark. Of the edges adjoining the non-illuminated side of the board, the known methods are capable of measuring only those whose distance from a reference plane is greater than that of the adjacent edge at the illuminated side. The aim is also to be able to measure edges whose distance is smaller. This is achieved by a special arrangement of the receiving device 9, 10 which produces the images.

Patent DE-3319686-A1 (DE)
Title: Water-saving single-chamber flushing cistern for toilets
Inventor: BOERNER HELMUT
IPC: E03D1/14
Filed: 1983-05-31
Abstract: By enforcing saving measures in the household, 10% of the amount of water supplied, which in 1981 amounted to 3,647 million cubic metres, can quite easily be saved in just a few years. However, saving drinking water when flushing the toilet, which accounts for 32% of the total amount of water supplied, conflicts with DIN standard 19542, the revised version of which is planned. Up until now, industry therefore saw no necessity to concern itself with water-saving technologies, so that a definitive judgement still cannot be passed on the numerous patent applications. The designs presented by companies at the ISH in March 1983 in Frankfurt can only be regarded as stopgaps with respect to the universal demand to save drinking-water. The suggestion to the effect that the flushing process can be interrupted by the user at will must be regarded as nonsense. The majority of patent applications are based on a two-chamber system, which fulfils the demand for a metered discharge of water but which would give rise to additional costs for the manufacturers of flushing cisterns as a result of changes in production. With the present invention, the inventor has complied with the demand for a metered discharge of water (about 3 litres for the short flushing process and about 9 litres for the long flushing process) in that he has only completely redesigned the prior-art outlet device (bell), but has retained the basic elements of the bell. In this way, it is possible for only that amount of water necessary for the respective flushing actually to be discharged. The user is not thus continually faced with the necessity of having to fix himself/herself how much water is to be used for the respective flushing. This invention thus fully complies with the demand for saving drinking water while observing hygiene regulations.

Patent DE-3416271-A1 (DE)
Title: Stirling motor
Inventor: BECKER FRIEDRICH
IPC: F02G1/043
Filed: 1984-05-03
Abstract: The invention relates to a piston heat engine with external combustion. In a cylinder chamber is a piston acting on both sides, which in a working cycle utilises the expansion force of a heated gas on the one side, and on the other side, under cooling, compresses the gas from a preceding working cycle. The residual heat of the working gas is utilised by a regenerator for a new working cycle. The compressed and cooled gas is collected in a cylinder, small in relation to the working cylinder, likewise with a piston acting on both sides, in order, during the working cycle, to be driven into the working cylinder utilising the expansion force of the heated gas. The small cylinder, the regenerator and the associated valves can be accommodated inside the working piston. The necessary pipelines are thereby shortened considerably.

Title: Device for the venting of fuel tanks, especially in motor vehicles
Inventor: SCHEURENBRAND DIETER
IPC: B60K15/035
Filed: 1984-05-11
Abstract: In fuel tanks, which are equipped in the upper area of the tank interior with an expansion tank connected to an expansion line leading into the open, in order to prevent fuel from being able to pass into this tank and flow out into the open a double-armed pendulum element is provided at each of the open ends of the expansion tank, standing off in front of these, the one arm of which carries a closing part and the other a weight. In order, for example in the event of lateral turning of the fuel tank due to an accident, to ensure a closure of the open ends of the expansion tank for as long as these are situated separately or together in the fuel, it is proposed to arrange the weight so that it can move on the pendulum elements in a plane perpendicular to their swivel axis and to design the movement space of the weight, starting from its rest position when the fuel tank is in its normal position upwards and towards the adjacent tank end wall extending in the vehicle's longitudinal direction so that with the fuel tank in the head position the centre of gravity of the weight is located in the area of the horizontal plane containing the swivel axis of the pendulum elements.

Patent DE-3436375-A1 (DE)
Inventor: RUSTIGE HAYNO DIPL ING
IPC: F04C15/00
Filed: 1984-10-04
Abstract: The pinion motor has two pinions which engage on their external sides (14, 15) the shafts of the pinions being supported on both sides in bearings (18 to 21). The bearing elements (19, 21) on one side of the pinions are designed with a lesser thickness than those on the other side. They are pressed against the lateral surfaces of the pinions by pressure regions (26, 27). The application forces of the thinner bearing elements (19, 21) against the inner wall (11) of the housing (10) must not be too large, since otherwise the starting-up behaviour of the pinion motor is impaired. These application forces are, inter alia, proportioned to the thickness of the bearing elements; the bearing elements on which the pressure regions are provided are not so thick.

Patent DE-3437536-A1 (DE)
Title: Arrangement of an additional filter in a vacuum-cleaner housing
Inventor: FLEISCHER WOLFGANG
IPC: A47L9/12
Filed: 1984-10-12
Abstract: The invention relates to an arrangement of an additional filter in a vacuum-cleaner housing. In this arrangement, the additional filter (6) is inserted in a mounting (5) in front of a passage opening (2) provided in a wall (1) of the vacuum-cleaner housing. A quantity of air necessary for proper cooling of the fan unit even in the event of severe clogging of the additional filter is ensured by virtue of the fact that the additional filter (6) is of flexible design and is supported in the mounting (5), against the force of the air stream, only partially in such a way that it can bend, in the clogged state, under the force of the air stream in the non-supported regions. Owing to the change in position of the additional filter (6) relative to the position assumed in the unloaded state, which is brought about by the bending, gaps are freed through which some of the air stream can flow. <IMAGE>
