Patent EP-0318075-A2 (EP)
Inventor: CORNELISSEN BERNARDUS HENRICUS
IPC: G06F7/508
Filed: 1988-10-28
Abstract: A digital integrated circuit, specifically a carry look ahead circuit consists of a carry transfer stage (12) and a logic network (10). The carry transfer stage (12) transfers the carry from a preceding stage to a next following stage unless altered by its associated logic network (10) which is able to provide symmetrical outputs. The logic network (10) comprises two or more half adders connected sequentially between a common node (38) in the carry transfer stage (12) and a voltage supply line (50). Each half adder comprises first, second and third active switching devices (K i , G i  and P i ). The third active switching devices (P i ) are connected in series between the common node (38) and the voltage supply line (50). The first and second active switching devices (K i , G i ) of each half adder are connected in series and a common junction of the series connected devices is connected to the common junction of its associated third active device and the next following third active device or the connection to the supply voltage line 50. Corresponding free terminals of the first and second switching devices constitute symmetrical outputs of the logic network. The first switching devices are activated in response to A i  * B i  = 1 where A i  and B i  are bits of corresponding significance to be added, the second switching devices are activated in response to  A i +B i    = 1 and the third switching devices are activated in response to A i ⊕B i  = 1.

Title: Screw press
Inventor: CLAASEN KARL HERMANN
IPC: B21J9/18

Abstract: The invention relates to a screw press (1) with a screw (3) and a screw nut (5), which are accommodated in a press frame (18), with a flywheel (7) running uninterruptedly in the same direction of rotation, with a clutch (19) actuable by a pressure medium, which is arranged between the flywheel (7) and the screw (3) and establishes a connection between the flywheel (7) and the screw (3) only during the downward stroke and partially during the working stroke, and with a hydraulic lifting device (7) for returning the ram (2), a plurality of oil outlet holes being formed in the region of flanks of the screw nut (5) for the purpose of lubrication. To improve the mounting conditions, the invention proposes that the oil outlet holes should be arranged in the form of bearing pockets (8) on the bearing flanks (11) of the screw nut (5), in order to form a hydrostatic bearing, and that the bearing force of the hydrostatic bearing should be set to a smaller force than that which corresponds to the maximum force of the screw press (1). <IMAGE>

Abstract: In order to prevent thermal distortion and always ensure a secure contact between the stirrup electrode (B) and the soldering point, at least the soldering web (Ls) facing the soldering point consists of a nickel-iron alloy with a nickel content of less than 50% by weight, i.e. with an extremely low coefficient of thermal expansion. By means of an electrically insulating ceramic coating (K) additionally applied to the underside of the soldering web (Ls), with its thermal response matched to the thermal response of the electrode material in order to achieve strong adhesion, discharge of the stirrup electrode current via low-impedance conductor paths can be ruled out. <IMAGE>

Abstract: A method of making an intermediate bulk container having zones (12) for the attachment of lifting loops (20) from a fabric (10) having eight such zones with lifting loops attached to the zones comprises attaching the opposite selvedges (14, 16) of the fabric together and then attaching the base (26) to complete the bag. The zones (12) are arranged in four pairs with a zone (12a) of one of the pairs being adjacent to one of the fabric selvedges (14). The side seam (24) of the bag so made is thus spaced from its adjacent corner. This means that all four lifting loops can be attached to the fabric while it is still in the flat state since no lifting loop has to cross the seam in the finished IBC> This form of construction lends itself to automatic stitching processes and radically increases speed of production.

Abstract: A pneumatic radial tire with highly durable bead portions includes a pair of bead portions (1), a pair of sidewalls (2) and a tread (3) extending between the sidewalls, and further includes as a body reinforcement a carcass (4) extending between ths bead portions and consisting of plies whose cores are radially arranged. At least one ply is turned up about bead cores (6) of the bead portions from inside to outside of the tire to form a turn-up portion. A carcass pass line in radial section of the tire in its self-holding position inflated to 5% of a normal internal pressure under no-load condition includes curvature changing areas (v) in a carcass profile curved toward the turned-up portions in the proximities of positions corresponding to a height (h) of turn-up ends of the ply from a rim diameter line (RL) to cause compressive stresses in the bead portions near to the turn-up ends of the ply by deformation of the carcass when the tire is inflated to normal internal pressure. With the above arrangement, the durability at the bead portions of the tire is improved to an extent required for prolongation of life time obtained by recapping the tire repeatedly.

Abstract: A method of producing a magnetic head core slider including integrally formed slider body (62) and yoke portion (56). The slider body has two parallel air bearing portions (46), while the yoke portion has a track portion (40). The slider body and yoke portion cooperatively provide a magnetic gap (30) open in the track portion. The core slider is prepared from an integral ferrite bar consisting of a first and a second ferrite block which give the slider body (62) and the yoke portion (56), respectively. Track-defining grooves (38) are formed by laser-induced etching in one surface of the bar, such that the grooves extend across the interface of the bonded two blocks. The grooves define the width of the track portion. An etching mask is applied to cover portions of the bar corresponding to the air bearing portions (46) and the track portion (40). The masked surface of the bar is chemically etched to form the air bearing portions, and a track protrusion including the track portion, such that the air bearing portion and the track protrusion have the same height.
