Title: Dummy element of dynamic semiconductor store - with compensation capacitance, compensating for parasitic voltage pulse on bit line
Inventor: MEUSBURGER GUENTHER DIPL ING
IPC: G11C11/4099
Filed: 1974-08-28
Abstract: One electrode of the compensation capacitance (14, 44) of the dummy storage element is connected in the first intersection (141, 441) to a compensation selection line (16, 46). The other electrode of the compensation capacitance (14, 44) is connected in the second intersection (142, 442) to a bib line (10, 20). The compensation capacitance (14, 44) is dimensioned in accordance with a formula, so that during the selection of a storage element the outgoing parasitic voltage pulse on the bib line (10, 20) is compensated by parasitic capacitances of the dummy element and a corresponding position (15, 45) on the compensation capacitance (14, 44). The dummy storage element is designed using metal-oxide semiconductor technology.

Title: Eccentric Ferris wheel amusement appts. - has eccentric wheel with suspended seats on axial struts rotated by radial weight displacement of riders
Inventor: SCHUETZ JOHANN
IPC: A63G27/00
Filed: 1975-07-08

Title: Control system for extrusion of plastics through annular orifices - derives electrical signal which is a function of issuing workpiece cross section and which is passed back to hydraulic mechanism of press
IPC: B29C48/09
Filed: 1975-07-24
Abstract: The outlet channel of the extruder nozzle is constructed with a core displaceable axially relative to the preferably conically-formed outlet opening. The outlet channel also cooperates with the displacement device. This system is modified so that a monitoring element is provided continuously scanning the path of the issuing section of material the appropriate position of the element being exhibited as an electrical signal via slider potentiometer. This magnitude acts on a function generator the output voltage of which serves as a function of the input voltage and a pre-set value. This information is used to regulate a control valve linked to the hydraulic system of the extrusion press. In contrast to the usual extrusion system for producing e.g. blow moulded articles, in which control of tube length and/or wall thickness, is which a number of parameters e.g. temp. moulding speed, material composition, pressure change uncontrollably it becomes possible to determine parameters instantly and to compensate for changes in these.

Title: Structural sliding bearing with friction modified over time period - uses disintegrating capsules holding grease or other friction influencing medium
Inventor: LANGE JOHANNES
IPC: E01D19/04
Filed: 1975-08-13
Abstract: A sliding bearing, for a building structure, is designed so that its coefficient of friction can be maintained permanently, or for a long period, or for the friction to be increased if required. For this purpose capsules (4), or similar units, are fitted between the parts carrying out the relative movement (1, 2). These contain a medium such as grease, which influences the friction resistance in the contact surface area (3). The sidewalls of the capsules are formed so that they are destroyed or released under the effect of time, temperature, pressure, radiation, ultrasonics, corrosion, aggressive media or other factors. The capsules may be made of self-destructive plastics.

Title: Shoulder pads of elastically deformable foam - are produced by making planar cutting of end of cylindrical blank in suction mould
Inventor: PUTZLAGER JOHANN
IPC: A41D27/26
