Title: Packet data communication system
Inventor: TYMES LAROY
IPC: H04L12/56
Filed: 1992-06-23
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Filed: 1990-11-21
Abstract: A mold (30) for the casting of aluminum sow ingots (40) includes a mold box having a bottom wall (32) and side walls (34, 36) that define a generally rectangular mold cavity (38). The bottom wall includes a central raised longitudinally extending protrusion (42) and side longitudinally extending protrusions (58) adapted to define corresponding depressions (48, 60', 60') in the ingot bottom (52). The side depressions (60') establish ledges for receiving a pair of fork lift blades or tines (25) entering the ledges from either transverse side of the ingot perpendicular to the ledges. A pair of transversely extending protrusions (44, 46) in the mold bottom wall establish corresponding transverse depressions (50) in the mold bottom that are perpendicular to the central longitudinal depression and equispaced from the central transverse axis by a distance enabling the pair of fork lift blades to enter the transverse depressions from a direction perpendicular to either of the longitudinally extending ingot sides to provide a dual entry feature for ease of handling. The depressions in the ingot bottom also define a surface to volume ratio enabling a solidification front in the molten metal to occur that moves from the ingot bottom surface to the top surface to significantly reduce formation of voids in the ingot and depression of the top surface. Also provided is an improved sow ingot having depressions in its bottom surface that facilitate solidification and stacking of the ingot.

IPC: H01P1/205
Filed: 1993-08-18
Abstract: A dielectric filter having at least two adjacently-positioned resonators extended therethrough. The two adjacently-positioned resonators are of trapezoidal cross-sections to form thereby trapezoidal resonators. By suitable selection of the configurations of such resonators, the amount of coupling between such adjacent resonators may be controlled. For instance a minor base side of the first trapezoidal resonator may be positioned adjacent to a corresponding minor base side of the adjacent trapezoidal resonator, or a major base side of the first trapezoidal resonator may be positioned adjacent to a major base side of the adjacent trapezoidal resonator, or a minor base side of the first trapezoidal resonator may be positioned adjacent to a major base side of the second trapezoidal resonator. Such electromagnetic coupling between the adjacent resonators is controlled by the relative configurations of such resonators rather than by increasing the spacings between such adjacent resonators.

Abstract: The gripper (10) has two gripper parts (11, 13), of which the one, first gripper part (11) is pivotable relative to the other, second gripper part (13). To hold a printed product (P), the free ends (12a, 14a) of the two gripper parts (11, 13) interact. The first gripper part (11) is mounted in a bearing part (21) by means of a ball joint (22), said bearing part being seated non-rotatably on a rotatably mounted hollow shaft (17). Arranged between the bearing part (21) and the first gripper part (11) mounted like a ball therein is a compression spring (27) which exerts a compression force on the first gripper part (11) in the closed position of the bearing part (21). The ball joint (22) is offset towards the rear relative to the pivot axis (17') of the bearing part (21). An extension of the limb (12) of the first gripper part (11) towards the rear is thus achieved, which leads to more favourable leverage ratios and, in the case of a given compression spring (27), correspondingly to higher clamping forces at the free end (12a) of the first gripper part (11). <IMAGE>
