Abstract: The invention concerns a partial cutting machine for use as a working or advance heading machine, the machine having a cutting arm which comprises a rotating cutting head, in particular a transverse cutting head, and is mounted so as to be vertically and laterally pivotable on a pivot mechanism of the moving gear frame provided with tracklaying gear. The machine is provided with a loading table, which is disposed on the moving gear frame at the front below the cutting arm, and a central conveyer which extends from the loading table between the moving gear tracks to the rear of the machine where it forms a vertically and laterally pivotable extending ejector arm. The moving gear frame is divided in the longitudinal direction and consists of frame parts which can be pivoted relative to one another in the lateral direction and of which the front part comprises the tracklaying gear, with the pivot arm and the cutting arm, and the loading table, whilst the rear frame part forms the carrier of the extending ejector arm of the conveyor, said arm being laterally pivotable with the rear frame part. The rear frame part is connected to the front frame part via a pivot connection so that it can be pivoted laterally and drawn thereafter. The pivot mechanism with the cutting arm (12) is guided in an axially displaceable manner on the front frame part (1) in the direction of the working face and in the opposite direction by means of an advance cylinder device (20). The pivot connection (3) is disposed between the two moving gear frame parts (1, 2) at a spacing behind the tracklaying gear (4) of the front frame part (1). The front frame part (1) is provided with claws (7, 11) which relieve the load on the tracklaying gear (4) during cutting and can be extended towards the worked stratum (10).

Title: Process for preparing cyano group-containing aromatic methylamines
Inventor: MIURA MOTOO
IPC: C07C253/30
Filed: 1998-02-04
Abstract: A process for preparing a cyanoarylmethylamine by hydrogenating only one of the two cyano groups of an aromatic dinitrile, which enables the preparation of the objective amine in a high yield through the reaction of the dinitrile at a high conversion by the use of a small amount of a catalyst under the reaction conditions of low temperature and low pressure. In this process, at least one member selected from among activated Raney catalysts prepared by treating Raney catalysts with hydrogen in solvents and regenerated Raney catalysts prepared by treating Raney catalysts with hydrogen in the presence of alkalis in solvents is used as the catalyst in preparing a cyanoarylmethylamine from an aromatic dinitrile. The amount of the activated Raney catalyst to be used is preferably 0.1 to 10 wt.%, still preferably 0.5 to 5 wt.% based on the aromatic dinitrile and that of the regenerated Raney catalyst to be used is preferably 0.1 to 50 wt.%, still preferably 0.5 to 20 wt.%  based thereon. The activated Raney catalyst is preferably one containing nickel and/or cobalt and prepared through activation in a solvent under a hydrogen atmosphere, while the regenerated Raney catalyst is preferably one prepared by subjecting a Raney catalyst which has been used for the preparation of a cyanoarylmethylamine from an aromatic dinitrile to regeneration with hydrogen in a solvent in the presence of an alkali.

Patent CA-2258403-A1 (CA)
Title: Printed circuit board header attachment station
Inventor: LEKX DAVID
IPC: B23K1/008
Filed: 1999-01-13
Abstract: The printed circuit board (PCB) header attachment station mounts a header (PCB) onto a PCB having pre-existing solder joints, such as underneath a direct mount IC chip. The apparatus applies a soldering paste to PCB lands configured to receive the pins of the header; nests the header component in stacked alignment with the PCB in order to bring the header pins into contact with the respective PCB lands; heats the PCB to a temperature approaching the reflow temperature of the solder in the pre-existing PCB solder joints; and actuates a compliant heating block or bar to heat the header pins to an extent sufficient for the pins to conduct enough heat to locally reflow the solder on the corresponding PCB lands without reflowing the solder in the pre-existing solder joints. The local reflow of the solder precludes solder reflow in the surrounding pre-existing joints which may coalesce under the direct mount IC chip and render the PCB  defective.

Patent CA-2260686-A1 (CA)
Inventor: LEE KYOO J
IPC: H04L12/54
Filed: 1999-02-04
Abstract: A data system, such as a computer network or a telecommunications system, has a base station and a number of nodes called network interface units (NIUs). Each NIU  is assigned to one of a number of groups of NIUs. The base station transmits special data to the NIUs indicating which groups of NIUs are currently authorized to transmit upstream messages to the base station, where only the authorized NIUs are allowed to transmit upstream messages. When message collisions in the upstream direction becomes a problem, the base station can reduce the number of NIU groups that are authorized at any given time to transmit upstream messages, in order to attempt to reduce the rate of message collisions. In one possible embodiment, each NIU is assigned horizontal and vertical group words that identify to which group it is assigned. The special data contain additional horizontal and vertical code words that are monitored by the NIUs. If the bits in the downstream code words appropriately match the corresponding bits in the NIU's assigned group words, then the NIU  recognizes that it is authorized to transmit upstream messages to the base station. Otherwise, it is not. The horizontal and vertical code words correspond to two-dimensional patterns that indicate which subset of NIU groups are authorized at any given time. By cycling through a series of 2D patterns, the base station ensures that each NIU is authorized at least some of the time. Depending on the number of bits in the code words, a back-off scheme can be designed with different back-off levels, each of which authorizes a different number of groups to transmit. The base station can progressively decrease the rate of upstream transmission by selecting back-off levels with fewer and fewer NIU groups authorized to transmit.

Patent CA-2260941-A1 (CA)
Title: Energy saving power control system
Inventor: WALKER N EDWARD
IPC: G05F1/66
Filed: 1997-07-23
Abstract: Apparatus and methods for AC power regulation for a wide range of complex capacitive and inductive loads which provide substantial reduction in power consumption while also providing a leading power factor. The system is self-adjusting for a wide range of loads and can reduce power consumption by 25 percent in lighting loads while producing minimal reduction in light output.  The system utilizes a main switch (17) consisting of back-to-back MOS  controlled Thyristor devices (MCTs) and a parallel capacitor bank (70) in series with the load (4). The main switch is initially turned off slightly in advance of the load current zero crossing, and this in combination with the capacitor bank (70) allows power to be reduced in a low noise fashion. The turn-off time is advanced gradually to regulate power at a target reduced level. At the target power level, load phase angle is measured and maintained to control the power savings ratio.
