Title: Automatic adjustment of veneer lathe nose bar height relative to knife during peeling
Inventor: ELY GARY W
IPC: B23Q15/013
Filed: 1995-03-07
Abstract: A veneer lathe apparatus and method are described in which the height of the nose bar roller relative to the knife is automatically adjusted during peeling by a computer control system. In addition, the two veneer exit gaps between the nose bar and the knife and between the nose bar and the knife backing member are automatically maintained substantially the same as or slightly greater than the veneer path width which is equal to the thickness of the veneer plus a clearance space of a predetermined amount. As a result the automatic control positions the nose bar as close as possible to the knife during peeling thereby greatly improving the quality of the veneer. The height of the nose bar is adjusted by moving a moveable wedge along a fixed wedge with a control cylinder in response to a computer generated control signal. A resilient hold-down device is employed for mounting the nose bar carriage to enable its horizontal movement and vertical movement with respect to the main carriages during peeling due to height adjustment and horizontal gap adjustment of the nose bar relative to the knife.

Title: Modem for selectively connecting to a land line or to a cellular telephone
Inventor: NAGEL PAUL E
IPC: H04M11/00
Filed: 1993-11-08
Abstract: A modem (12) is incorporated into a laptop computer (10) and directly connected to either a cellular phone (22), a land line (18), or both. The modem is provided with two connectors (14, 16), one for connection with a cellular phone or external DAA (24), the other for connection to a normal land line via an internal DAA (112). The modem selectively enables either the connec-tor for the cellular phone or external DAA, or the connector for its internal DAA. The modem defaults to selecting the cellular phone or external DAA if it is connected, and only if they are not connected selects the internal DAA. These defaults can be over-ridden by user commands. Further, the modem can independently power down a connected internal DAA, external DAA, or cel-lular phone to conserve power.

Title: Compressed air system to deliver dry and clean air
Inventor: KORYCKI LESZEK S
IPC: B01D45/12
Filed: 1995-05-11
Abstract: A compressed air system to deliver dry and clean air whereby the compressed air supplied by the air compressor is passed through a primary circuit of a heat exchanger and a liquid separator where it is cooled down close to the freezing point of the water so that the majority of the water vapor in the air will condense.  The condensate as well as majority of the oil in the air is removed from the air stream with a centrifugal action inside the liquid separator which consists of a precooling chamber, cooling lines, conical centrifugal separator section, vertical centre cavity and exit passage.   me superheated air leaving the liquid separator unit can be dried further by passing the air through the freezer dryer units where its temperature is lowered below the freezing point of the water so that the remaining water forms into ice crystals and will get attached to the inside walls of the freezer dryer.  The returning air from the liquid separator is guided through the secondary circuit of the heat exchanger before it enters the air reservoir tank.  The remaining oil particles as well as rust and dust in the air stream can be removed with an oil filter unit placed downstream  from  the  storage  tank.

Title: Process for hydrotreating heavy hydrocarbon oil
Inventor: KUBO JUNICHI
IPC: C10G49/00
Filed: 1995-05-25
Abstract: A novel hydrotreating process is provided, which comprises hydrotreating a mixed oil of a heavy hydrocarbon oil feedstock and at least one additive oil or partially aromatic ring-hydrogenated oil thereof in an amount of 0.3 to 15% by weight with respect to the feedstock, at a temperature of 330 to 460°C, a hydrogen partial pressure of 50 to 250 Kg/cm2, a liquid hourly space velocity (LHSV) of 0.1 to 4.0 hr-1 in the presence of a hydrotreating catalyst, the additive oil being selected from the group consisting of coal-tar oils, tar-sand oils, oil shale- or bitumen-derived oils, and oils obtained by coal liquefaction.  According to the process, coke formation, which cause clogging of heat exchangers, an increase in the pressure drop of preheaters, and a decrease in catalytic activity, can be greatly reduced.
Patent CA-2153608-A1 (CA)
Inventor: BRAUN EUGENE R
IPC: F16H1/22
Filed: 1995-07-11
Abstract: A compound vehicular transmission having a main section and an auxiliary section which includes an auxiliary countershaft gear assembly having an auxiliary countershaft, a first auxiliary countershaft gear fixed to the auxiliary countershaft and constantly meshed with an output shaft range gear,  and a second auxiliary countershaft  gear  selectively  coupleable  to  the auxiliary countershaft and constantly meshed with an intermediate  shaft  output  gear.   A  jaw  clutch  is provided for coupling either the auxiliary countershaft to the main countershaft, or the auxiliary countershaft to the second auxiliary countershaft gear.  This allows fewer gears to be utilized to achieve a desired number of speed ratios.  Since the auxiliary countershaft drive gears are clutched only when used,  this arrangement reduces spin back speed of the intermediate shaft to accommodate  smoother  and  faster  shifting  of  the transmission.  Alternative embodiments include the use of a two-speed master clutch splitter section or a two-position synchronizing clutch assembly as the input to the main transmission section.
Patent CA-2157587-A1 (CA)
Inventor: SEIP D ERIC
IPC: H05K3/38
Filed: 1994-03-02
Abstract: Drum or smooth side-treated metal foil can be used either as an intermediate product for use in the manufacture of laminate or as a part of the finished laminate to be used in the manufacture of multi-layer printed circuit board (PCB) packages. By treating the drum or smooth side (11) of metal foil (10) with a bond strength enhancer (13) rather than treating the matte side or rough side (12), or both sides, several time-consuming and costly steps can be bypassed in the manufacture of multi-layer printed circuit boards (PCB) while the integrity of the metal foil, laminate and multi-layer PCB are not compromised and are actually enhanced by way of improved impedance control and adhesion characteristics after relamination. This novel foil can be initially bonded to substrate on either side before circuit formation and can be used either as an internal foil layer or as a foil cap. The invention includes methods of manufacture of the metal foil, laminate and multi-layer printed circuit board. A variation of the invention involves a component or tool for use in manufacturing articles such as printed circuit boards. The component is a temporary laminate constructed of one or more sheets of drum-side-treated copper foil mounted on a sheet of aluminium. The copper foil, which, in a finished printed circuit board, will constitute a functional element, has a drum-side, which has been subjected to an adhesion-promoting treatment, and a rough side, which has not been subjected to the adhesion-promoting treatment. The sheet of aluminium constitutes a discardable or reusable element. Either surface (treated drum-side or untreated matte side) of each copper sheet can be bonded to the aluminium, depending on which embodiment of the basic invention is being used. The side of the copper foil not bonded to the aluminium will be bonded to the resin in the next step.
