Abstract: An engine (10) that is applicable for automotive and truck use but is also adaptive for other power producing uses and can be designed with two or more cylinders. The engine has multifuel capabilities. Two reciprocating cylinders (70, 72) are housed within an outer cylinder (36). A piston (126, 128) is housed within each of the two reciprocating cylinders (70, 72). The reciprocating cylinders (70, 72) are so designed that after combustion in one reciprocating cylinder, the movement caused by the combustion will aid in setting up the circumstances necessary for combustion in the opposing compression chamber formed by the opposing reciprocating cylinder and piston. Due to this design, the horizontal movement caused by the combustion in both opposing reciprocating cylinders (70, 72) and both opposing pistons (126, 128) is useful. The horizontal movement of the reciprocating cylinders (70, 72) and pistons (126, 128) is translated into rotational energy in the crankshaft (24) by three scotch yokes (118, 120, 145) each scotch yoke (118, 120, 145) housing a scotch block (156, 158, 160), each scotch block (156, 158, 160) in turn surrounding one crankthrow (162, 164, 166).

Abstract: 1.         Cigarette pack, especially hinge-lid box.   2.1.       Known conventional cigarette packs, especially those with a hinge-lid box (10), an inner blank (29) made of tin-foil and possibly an outer wrapping made of plastics foil are not suitable for disposing of smoked cigarettes (waste-cigarettes 48). It is felt to be undesirable that smoked cigarettes are thrown away individually. This goes especially for "artificial cigarettes" which have recently appeared on the market.   2.2.       In order to achieve an improved waste-disposal, the present cigarette pack, especially as regards its em-bodiment with hinge-lid box (10), is provided with a waste compartment (47) for holding waste-cigarettes (48). Part of the inner blank (28), namely its rear-wall (30), forms a partition between the waste compartment (47) and a cigarette compartment (46). Smoked cigarettes are reinserted into the pack through an insert-opening (54).     2.3.       The cigarette pack practically does not differ from conventional cigarette packs regarding its dimensions and shape. But it still offers the possibility of dis-posing of the cigarette pack including all smoked cig-arettes as a whole.

Abstract: A road path searching apparatus applicable to a car navigation system is disclosed.  Road map data with different detailedness for defining a predetermined area is stored previously in a memory device.  First, nodes Nai and Nbj adjacent to each of the search nodes Pa and PB are detected based on map data of high detailedness (step 13).          When nodes Nai and Nbj exist on a map of lower detailedness (steps 14, 18), a map of one level lower detailedness is selected as a map to be used in the searching process (step 19).  Accordingly, as following searching process is performed based on the map data of lower detailedness, time required for processing is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE         A memory medium includes a memory layer of a polymer liquid crystal and a reflection layer disposed on a substrate.  A record part having a different refractive index from that of a non-record part is formed in the memory layer so that the record part and the non-record part have a difference in optical thickness of the memory layer.  In a reproduction step, the memory medium is irradiated with a reproduction beam of coherent light so that the reproduction beam is transmitted through the memory layer, reflected at the reflection layer and re-transmitted through the memory layer, during which the reproduction beam is subjected to interferential diffraction due to the optical thickness difference between the record part and the non-record part to allow readout of the recorded data.

Title: Receiver for data transmission system with nonlinearities
Inventor: BERGMANS JOHANNES WILHELMUS MA
IPC: G11B20/18
Filed: 1990-06-22
Granted: 1999-10-26
Abstract: A system for transmitting a data signal at a symbol rate 1/T through a noisy dispersive channel to a data receiver is described. The channel introduces intersymbol interference and noise into the transmitted data signal. The receiver estimates the most likely sequence of transmitted data symbols by keeping track of candidate data sequences that are recursively updated on the basis of likelihood measures which are determined by estimating hypothesized channel outputs in the absence of noise. The hypothesized channel output signals in the absence of noise are estimated using one or more look-up tables. As look-up tables are ideally suited to store nonlinear input-output relations, they can account for any nonlinearity of the channel. Furthmore, because they all operate on digital data symbols, these look-up tables are often more conveniently implemented in digital technology than the linear weighing networks in receivers of the above-mentioned prior art. In this way the ability to handle nonlinear ISI is generally accompanied by a decreased receiver complexity.

Title: Screw device for fixing prostheses to bones, a method for applying the device, and the relative instrument
Inventor: VRESPA GIUSEPPE
IPC: A61B17/86

Granted: 2001-12-25
Abstract: In a screw device (10; 80) for fixing prostheses to bones, the threaded shank (14) comprises a core (32, 34) of overall frusto-conical shape. The screw has a cylindrical neck (12) of diameter equal to or greater than the maximum diameter of the thread. This latter is of two different types, namely a first thread (26) of large pitch for fixing into the trabecular bone tissue (52) and a second thread (28), which can be of the self-tapping type, for fixing into the cortical bone opposite the point at which the screw is inserted into the bone. The second thread (28) has a number of starts which is a multiple of that of the first thread (26). For orthopedic use the screw (80) can comprise a third thread (128) on a part of the neck (112) for fixing into the relative cortical bone (50).      A method for applying the screw device (10; 80) consists of forming a precision hole (90) in the bone, tapping said hole with a tapper (60; 100), and screwing the screw (10; 80) into it. The precision hole (40) is obtained by using a cutter (100) in the shape of an inverted "wedding cake", then reaming the obtained cavity with a manual reamer (1-10).
