Abstract: A glass fiber-reinforced composite material is produced by treating glass fibers with a silane composition comprising silane molecules having amine functional groups and silane molecules having ethylenically-unsaturated functional groups; admixing the treated glass fibers with a polyolefin resin, and a fiber bonding agent comprising a polymerizable unsaturated organic compound having at least two polymerizable unsaturation groups, a vinyl-polymerizable unsaturated, hydrolyzable silane, and a free radical generator, and exposing the resultant mixture to conditions of temperature and pressure sufficient to cause the formation of a glass fiber-reinforced composite material. The use of the silane composition promotes improved impact strength of the composite.

Abstract: A Geiger-Muller tube designed for use in an environment (for example, mounted on a rock drill) where subjected to mechanical shock and vibration has a tensioned anode wire (1) secured between first and second mounts (11,21) and (12,22) at opposite ends of the tube envelope. The wire tension is adjusted to a high value with a screwible-adjustment means (22,23,24) which is locked (*25) in the adjusted position, so that the natural frequency of vibration of the tensioned wire 1 does not resonate with (and may be much higher than) the frequencies to which the tube is subjected in use. The wire frequency is typically in excess of 400Hz and even 500Hz. The adjustment means (22,23,24) may be included in the mount (12,22) via which the envelope is evacuated and back-filled with the ionizible gas, and a gas-tight seal (30) can be provided around this part of the mount (12,22), for example by sealing off the gas pump tube. However the adjustment means may be designed into another part of the tube, for example using telescopic parts of the envelope whose sliding junction is made gas tight with a flexible seal.

Packets for use with the network comprise an address portion encoded in a broadcast format or in a shorter point-to-point format and an address type character identifying the type of address in the address portion. The nodes of the network respond to the address type character of a received packet. By selecting the appropriate decoding format for the packet address portion, a packet select unit decodes the address portion in accordance with the selected decoding format and selectively connects the packet to the network outputs.

Abstract: A two-dimensional phased array ultrasound imaging system (400) distributes signal delays between its probe (402) and its base section (404). The transducer elements (414) in the array are grouped and relative delays between elements of a group are introduced within the probe. Once the intragroup delays are introduced, the signals from the elements of a group are combined to generate a group signal. A group signal is generated for each group and, collectively, the group signals are transmitted to the base section via a multi-wire cable (426). Delays between groups are introduced at the base section. This distribution of delays maintains power dissipation within the probe at a tolerable level while requiring only a manageable number of data and signal lines between the probe and base section.

Abstract: There is disclosed a non-volatile semiconductor memory device wherein a pair of memory cells (1A, 1B; 2A, 2B) constituting one bit data memory unit are connected to a data line (100) in a manner that their drains are commonly connected. When compared to the case where drains of two memory cells are respectively connected to different data lines, the number of the connecting portions between drains and data lines is reduced and the area required for connection is lessened. Thus, a semiconductor memory device satisfactorily miniaturized from the viewpoint of practical use is provided. Further, since there is employed an arrangement such that the one bit data memory unit is comprised of two (a pair of) memory cells, the reliability can be improved. Individual select transistors may be arranged between the drain common junctions in the pair of memory cells, respectively, or a common select transistor may be arranged therebetween. In addition, the sources of the two memory cells may be respectively formed as individual sources.

Abstract: The present induction-heating device (10) serves for heating electrically conducting materials up to temperatures exceeding 300 DEG C. The device (10) comprises an open core (12) made of a ferric material. A Litz wire coil (15) is wound around the core (12). A power source (17) is connected to the ends (16) of the coil (15) so as to produce an excitation current in the latter, inside a frequency range varying from 12 to 25 kHz, in such a way as to generate a magnetic field when magnetised. Magnetic flux concentrator tubes (18) made of an electrically conducting material are arranged around the coil (15) and near the core (12), and are embedded in a material (19) which conducts heat but does not conduct electricity, for the purpose of maximising the useful flux. A cooling fluid circulates through the concentrator tubes (18) so as to cool the tubes (18), the core (12) and the coil (15). An induction zone is defined by the magnetic field generated between the opposing poles (13, 13') of the core (12) and penetrating the surface of the part to be heated. The part is heated by the eddy currents generated by the variable magnetic field on the surface. …<IMAGE>…
