Title: Process for detecting a water deficiency in the water inflow in a program-controlled washing machine
Inventor: STEHR THOMAS
IPC: D06F33/34
Filed: 1981-11-24
Abstract: In a program-controlled washing machine which is equipped with separate inflow paths for cold and hot fresh water, a water deficiency occurring in the inflow of cold and hot water is to be detected, a signal transmitted to the control and the attendant given an indication as to the cause. In the solution for detecting a water deficiency, the water level in the tub is measured respectively before the inflow of cold and hot water and for a predetermined period of time thereafter, the two measurement results are compared with one another and, if the difference falls below a predetermined minimum value, the program cycle is cut off and an optical and/or acoustic fault alarm triggered. The process according to the invention is carried out by an automatic drum-type washing machine which contains a master control part (for example, a microcomputer), solenoid valves for the cold-water and hot-water inflow and a slave controlled part assigned to the process according to the invention. The latter consists essentially of three prime elements (3, 7, 15) for the cold-water inflow, level steadying and hot-water inflow and of an electronic level sensor (17), a sample-and-hold amplifier (6), an analog switch (10), a comparator (11), an error flipflop (12), a short-time element (5) for the acquisition time of the sample-and-hold amplifier (12) and a short-time element (9) for the comparison time of the comparator (11). <IMAGE>

Title: Cardboard knife having a knife-blade holder comprising a handle
IPC: B26B5/00
Filed: 1982-01-30
Abstract: In a cardboard knife having a blade holder of substantially rectangular basic shape, the blade holder, together with a handle body, consists of a metal part, e.g. a zinc die-cast part. A catch projection passing through the knife blade in a recess is formed in a spatially fixed manner on the blade-locating face of the blade holder forming an undercut retaining groove. Slidably arranged in the undercut retaining groove is a protective plate which overlaps the blade except for a protruding corner thereof. The protective plate forms a spring web merging materially integrally into the protective plate both at its front and at its rear narrow side and carrying catch recesses. The catch recesses, facing the blade, of the spring web cooperate with the catch projection and permit operationally reliable spring locking of the protective plate in an advanced protective position and in a retracted working position.

Title: Active media-free inertial rudder
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G01C19/00
Filed: 1982-02-15
Abstract: The coaxial gyro-rudder design of the main application is improved insofar as only two exogenous locking mechanisms are now necessary, which are placed coaxially to A-A in the shields of the rudder, even when an arbitrary multiplicity of gyro-spokes is installed per unit. Said exogenous locking mechanisms, of spherical or latch design, are provided with much space in this arrangement and can be chosen to be quite large, in contrast to the main application where they are coaxial to C-C. The drawback of the design (Figure 1), as in the main application, is that, in contrast to the binaxial rudder which, for the first time in the history of gyro-rudders, was able to straighten the gyroscopic couples simply by the application of the sin<2>  phi principle without locking mechanisms, locking mechanisms once more become necessary in addition to the sin<2>  phi  principle which is also applied in this case. This drawback is overcome completely by endogenous locking, the exogenous locking mechanisms (10, 12) being omitted again, and in contrast to Figure 1 the frictional components (18-24) being dispensed with and, for the purpose of reversing the rudder steering moment, the input being reversed, as reversing of @3 in endogenous selective decoupling would not serve the purpose and reversing can only be achieved by turning @1. <IMAGE>

Title: Inflatable boat for stern motor drive with a U-shaped buoyancy tube
Inventor: VOLKHAUSEN ROLF
IPC: B63B7/08
Filed: 1982-02-16
Abstract: The invention relates to an inflatable boat for stern motor drive with a U-shaped buoyancy tube, the stern legs of which are connected via a transversely running transom serving as the motor mounting and which has a keel which can be shaped. By means of a keel tube, inserted between insertion base and bottom skin, the keel can be shaped in such a way that its full shape (cross-section) is obtained after about 1 DIVIDED 3 of its length and this shape (cross-section) is retained up to the stern. In this arrangement, the bottom skin is reinforced in the rear third by an insertable, rigid bottom and it is thus given a hydrodynamically favourable design. <IMAGE>
Patent DE-3212562-A1 (DE)
Inventor: LAUDENBERG HANS-JOSEF DR ING
IPC: F01L3/02
Filed: 1982-04-03
Abstract: The valves, particularly the exhaust valves of internal combustion engines, are damaged by high temperatures and corrosion. The cooling allows to reduce the temperature and hence corrosion. The transfer of heat to cooling water results in an energy loss, which reduces the engine efficiency. Owing to the combination of good heat conducting materials with a corrosion and temperature shield made of a bad conductor material, it is possible to reduce the heat transmission to the inside and therefore to increase the engine efficiency. The portion of heat transmitted to the inside may be conducted, by means of the good conductor material, in the stem and in the cooling water. The core and the stem remain cooler and may better comply with the requirements of heat resistance in order to reduce deformations.

Title: Self-supporting stair arrangement
Inventor: NOGVA OLAV
IPC: E04F11/035
Filed: 1982-04-21
Abstract: According to the invention, the system consists of a U-shaped bracket which can be produced from, for example, wooden composite material, plastic, steel glass, concrete or metal and formed in circular, square or rectangular shape. The U-shaped brackets, of which in each case one is situated on both sides of the width of the step, are arranged so as to be displaceable in the vertical plane, in such a way that the height difference between the brackets determines the step height of the stair, and that the brackets are firmly connected to one another by means of two screw bolts, and that the upper, free ends of the brackets are provided with bored holes (bored hole) for fixing the steps themselves. In a modified embodiment, which is intended for use when joining together two brackets and adjusting the step height, one bracket is arranged with a recess, whereas the other bracket has a milled track, with the result that a threaded bolt with an adjustable nut is mounted in engagement with the recess of the abutting bracket. In another embodiment which is intended for joining together two brackets and regulating the step height, the brackets are arranged with sawtooth-shaped recesses made downwards over the brackets. To be able to determine the step height more easily during erection at building sites, a boring-measuring instrument is provided, which consists of an upwardly projecting arm or pin displaceably fixed to a scale and is provided with two holes for boring the upper holes of the brackets when joining the latter together.

Title: Adjustable insert barrel for centrally fired pellet cartridges for fitting into shot-firing guns
Inventor: LOEFFLER ERNST
IPC: F41A21/10
Filed: 1982-05-14
Abstract: Adjustable insert barrel for centrally fired pellet cartridges for fitting into shot-firing guns, with clamping free of bending stress within the shot barrel and with a freely oscillating barrel muzzle. The adjustable insert barrels known hitherto in the construction of hunting weapons for centrally fired pellet cartridges present many problems in terms of fire power and a constant hit-point position because of the bending stresses occurring during adjustment and clamping. The insert-barrel muzzle cannot oscillate freely and the adaptation work for the various shot-barrel lengths and diameters involves a very high outlay. In the partly conventional clamping by means of rubber rings, the shot barrel is sealed off, so that condensation water and therefore rust can form in the shot barrel. To solve these problems, the insert barrel is designed with an adjusting and clamping device free of bending stress and with a freely oscillating barrel muzzle. The insert barrel can expand virtually freely in the longitudinal direction under heating and is ventilated within the shot barrel. The retention or locking of the adjusting or clamping device guarantees an absolutely constant hit-point position during subsequent removal and refitting. The insert barrel can be produced as standard and economically in terms of mass production for various shot-barrel lengths and diameters and needs only a little adaptation work, so that it can be produced cheaply and easily for shot-firing guns, especially for combined hunting guns, such as rifle/shotgun combinations and three-barrelled guns.

Patent DE-3226388-A1 (DE)
Title: Paper machine
Inventor: KOCHENDOERFER MICHAEL
IPC: D21F9/02
Filed: 1982-07-15
Abstract: The paper machine comprises at least one water-permeable drainage belt (wire 1 or 12) to form a fibre mat, in particular a ply of a multi-ply fibre mat, and a headbox device (15 or 16) for feeding a stock suspension which is to be applied in a free jet to the drainage belt (wire 1 or 12). Between the headbox device (15) and the section (1a, 12a), running along the latter, of the drainage belt (wire 1 or 12), at least one deflection device (51), which can be introduced into an edge region of the free jet, is located for separating off and removing a part stream of the stock suspension. This arrangement allows, for example, an infinitely variable adjustment of the format width of the fibre mat to be produced. In this case, the part stream diverted before the formation of the fibre mat is kept away from the downstream working regions of the paper machine, in particular from a second fibre mat located there, and, if desired - for reutilisation of the unmixed fibre material - recycled into the stock feeding system upstream of the headbox device (15 or 16). <IMAGE>

Title: Protective device for the dredging bucket extension arms of portal dredging buckets
Inventor: WIRSCHING KNUT ING GRAD
IPC: B65G65/00
Filed: 1982-11-27
Abstract: In all methods for removing heaps of bulk material which necessitate lateral movement of the dredging bucket extension arm into the material, compression and/or hardening of the material in the heap, for example due to freezing, give rise to excessive transverse and/or lateral forces, which may lead to warping or other permanent deformation of the dredging bucket extension arm; this applies particularly to dredging bucket extension arms of great length. To provide protection against impermissible lateral forces and to prevent permanent deformation of the dredging bucket extension arms of portal dredging buckets, the latter are provided with a safety device according to this new proposal. The safety device comprises a traction mechanism on each of the long sides of the dredging bucket extension arm at a small distance from the latter along the portal leg adjacent to the point of the dredging bucket, which traction mechanism is attached by means of prestressing to the dredging bucket portal, and also at least one monitoring element responsive to changes in length or forces which is connected to the circuit of the running gear motor and which switches the running gear motor in a manner dependent on changes in the length of or force exerted by the traction mechanism.
