Patent NL-7804831-A (NL)
IPC: C04B16/06
Filed: 1978-05-05
Abstract: A fibrous reinforcing element made from oriented polyolefin material for reinforcing a matrix material such as cement has longitudinally varying cross-sections and frayed surface portions from which fibrils extend. The element has cross-sections which vary along its length, a characteristic which combines with the fibrils of the frayed surface portions to facilitate anchoring of the element in the matrix. The anchoring and strength characteristics make the element particularly useful for constructing cement building products or any product produced from a matrix binding agent. The element is in the form of a fiber made from a polyolefin film which is stretched at least fifteen times and then cut by cutting means along lines at least partially transverse to the direction of orientation. In the preferred embodiment a building product formed from a matrix of Portland cement has dispersed therein, a plurality of fibrous reinforcing elements at least a portion of which are the individual polyolefin fibers described in accordance with the invention. By uniquely providing a combination of the inventive fibers with fibers of other types within the cement matrix, improved anchoring and dispersion of the fibers is achieved, while the improved strength characteristics of the elements contributes to a building product of unusually improved strength.

Title: Semiconductor memory circuit
IPC: H01L29/739
Filed: 1995-03-16
Abstract: A semiconductor memory device has a series of semiconductor memory cells in a common semiconductor body. Each memory cell is composed of a breakdown-type bipolar transistor having a channel zone and a capacitance of two first and second electrode zones separated from one another by insulating material, the channel zone being delimited, at least locally, by an annular gate zone (control zone) connected to a first conductor, said channel zone extending in the direction perpendicular to a principal plane of the semiconductor body between a feed zone (supply zone) connected to a second conductor and a storage zone forming the first electrode zone of the capacitance. The storage zone is highly doped and disposed separate from the feed zone. The channel zone is depleted and has a high specific resistance (resistivity) and such a low dopant concentration and such dimensions that a voltage barrier for charge carriers is formed in the channel zone, said voltage barrier, under the control of the voltage applied to the gate zone, imparting unsaturated current-voltage characteristics to the transistor. This configuration confers a high operating speed and high density of memory cells to the semiconductor memory device.

Abstract: 1482006 Mixing apparatus ACME-CLEVELAND CORP 14 Oct 1974 [19 Nov 1973] 44510/74 Heading B1C In apparatus for mixing foundry sand with a liquid binder, the binder constituents are supplied by pipes 51, 52 to the interior of a rotor 15 whence they are projected centrifugally through vertical slots 60 in the rotor walls and strike a falling curtain of sand. The latter is controlled by a gate 29 and is directed by guide surfaces through a central opening in a member 33 to a dished member 17; the members 17, 33 form an assembly rotating coaxially with but independently of the rotor 15. The sand is upwardly directed by the dished member 17 to strike the lip 44 of member 33, by which is it redirected downwardly and falls along the inner surface of the housing 54A, 54B. The path of the sand thus passes three times through the zone of projection of the liquid binder, at 71A, 71B and 71C. The dished member 17 carries a fan blade 157 to prevent material adhering to the inner surface of the housing. Air or other gas may also be supplied through a hollow support 56A and passages 118 to fan blades 109 mounted on the member 17, and through apertures 119, 126 to the interior of the rotor 15. The housing 54A, 54B is hinged at 70 to permit replacement of a liner 94, and the members 17, 33 may also have liners. A modified rotor, Fig. 3, enables two binder components to be dispensed in parallel planes. The rotor is driven at 5000 to 15000 rev/min or at a peripheral speed of 3000 to 16000 ft/sec.
