Title: Pistonless internal combustion engine (diaphragm motor)
Inventor: BREITGRAF HANS J
IPC: F02B75/02
Filed: 1988-01-05
Abstract: Pistonless internal combustion engine (diaphragm motor), especially as prime mover for motor vehicles. In conventional reciprocating piston engines, damage and malfunctions, which sometimes seriously impair the functioning and the service life of the engines, occur on cylinders, pistons and piston rings due to sealing and lubrication problems. In order to solve these problems, the piston reciprocating in the cylinder of the reciprocating piston engine, which piston serves for movably sealing off the combustion chamber (number 16 of the drawing) from the crankcase, is replaced by a fixed, unlubricated diaphragm (4). The pressure applied to the diaphragm (4) by the heat energy of the combustion gases (14) is converted in a hydraulic cylinder (1) filled with a hydraulic fluid (3) into hydraulic energy and thence into mechanical energy by the hydraulic piston (2) moved in the hydraulic cylinder (1) by that hydraulic energy. <IMAGE>

Title: Orthopaedic pillow
Inventor: FISCHER JOSEF W DR MED
IPC: A47G9/10
Filed: 1988-06-08
Abstract: In order to avoid discomfort that may result from damage to the cervical spine it is conventional to use orthopaedic pillows which have a plate-shaped part of an elastic foam intended to support the head and provided with a reinforced edge portion forming a type of bolster. These pillows are deficient in that their size is inadequately adapted to the personal constitution of the user. The invention provides an orthopaedic pillow which has two rectangular, essentially congruent plate parts (1, 2) arranged one on top of the other in a common fabric covering (21) which are made, for example, of a soft foam. One of these plate parts (2) is provided on its side facing the other plate part (1) with a peripheral foam frame (3) whose sections (5 to 8) allocated to the individual edge portions of the plate part (2) have different widths and/or heights and hence different supporting properties. Moreover, a differing design of the plate parts (1, 2) or the arrangement of an intermediate part (9) makes it possible for the cushion to have two sides of different hardness. This results in many variations which permit people of different constitutions to find the optimum position of the pillow. <IMAGE>

Title: Device for capturing the working time of machines
Inventor: FENINGER CLAUS
IPC: G07C3/10
Filed: 1988-07-30
Abstract: A device (1) is used to capture the working time, and if required also the costs, of machines (2 or 3) by means of a time capturing device which is contained in a programmable computer (4). At least one input device (5) is connected to the computer (4), to input and store the data which characterises the current work process. Also, at least one control line (8) to a contactor (9), relay or similar is connected to the computer (4), and this contactor (9) or switch is arranged in the current feed to the machine (2, 3). The contactor (9) can be triggered by the computer (4) to enable the current feed to the machine (2, 3) only after all the data has been entered and checked by the computer. Thus, to switch on the machine (2 or 3), the user has to enter the data which is required for time capture at the input device (5), correctly and completely, since the machine can start to work only after this data has been checked. <IMAGE>

Title: Bulky material made from glass fibre, preferably for reinforcing various plastic materials
Inventor: VOGEL BERND DR ING
IPC: D04H3/105
Filed: 1988-09-24
Abstract: The invention relates to a bulky material made from glass fibre. The material produced in the glass industry during the further processing of glass-fibre spinning threads can be used for reinforcing various plastic materials, such as polyester resin, phenol resin, epoxy resin and PUR resin, and is suitable particularly for processing by the vacuum-injection, pressure-injection and pressing methods. According to the invention, the product consists of glass-fibre spinning threads which are deposited next to, in, behind and above one another in the form of a loop, sling or ring and of which a significant proportion is broken apart and fanned out, the remaining loops, slings and rings being connected flexibly, but also permanently, to the material perpendicularly to the sheet-like extension of the latter. There is no tying from the top side of the material to the underside, and displaceability is guaranteed, without the binding points being destroyed, whilst the furry structure is preserved. Additional sewing threads in the edge region and the additional use of also other thread-like materials are possible.
Patent DE-3833798-A1 (DE)
Inventor: HELLDOERFER REINHARD DIPL ING
IPC: G01C17/38
Filed: 1988-10-05
Abstract: A process is disclosed for determining the interference from consumers and units that can be switched on and off in vehicle electronic navigation systems having a display, a computer and a magnetic field sensor for determining the orientation of the earth's magnetic field from the total field (H) measured by the magnetic field sensor. For this purpose, an elliptic locus curve (O) is stored in the computer when the consumers are switched off; the centre (O) of the locus curve is offset in relation to the point of origin of the vectorial diagram around the vector (Hs) of the hard magnetic interference field present at the magnetic field sensor. In order to check the extent of interference from additional consumers, the total field (H, Hv1) active at the magnetic field sensor is first measured with switched on and off consumers, while the vehicle is stopped, the vector ( DELTA s) of the interference field variation is derived therefrom and the maximal angular error ( DELTA  phi ), as a function of the interference field variation ( DELTA s), is calculated with an algorithm by means of the locus curve (O). These steps are repeated with every additional consumer until all consumers or units that cause errors exceeding a predetermined limit value have been detected.

Patent DE-3940424-A1 (DE)
Inventor: LIPPMEIER WILLIAM CHARLES
IPC: F02K1/80
Filed: 1989-12-07
Abstract: An interflap segmented seal 30 is provided for use between adjacent flaps (28) (Figs. 1, 10, 11) of an axisymmetric vectorable exhaust nozzle (10) in order to minimize flow loss therebetween when the flaps are pivoted through different angles in order to turn the exhaust flow and vector the thrust. The overlapping seal segments 56 are mounted to a backbone 50, having an elliptical cross-section, by a flange 60 with a lobed hole 72 in it through which the backbone passes. Spacers 64 between the flanges axially position the individual segments from each other. The mounting arrangement permits twisting of the seal and variable movement between adjacent flaps 28 to produce different angles between the sealing edges of the flaps which are often skewed with respect to each other and the flexibility afforded by the seals 30 allows the seals to minimize the leakage between the flaps and the seals. <IMAGE>
