Abstract: The present invention relates to a laminated foil, the raw materials of which can be separated and recovered. The bond (14) between the layers (12, 16) of the laminate keeps the layers together when no external force is exerted on the layers, but allows the layers to be separated from each other either by hand or mechanically. Bondless edges (22) have been formed on the foil, i.e. the bonding material has been removed from the edge in order to facilitate the separation of the layers. A foil like this can be cut into blanks to be used as wrappings in packing. Preferably the bondless edges are formed at the packing machine. Thereby it is easy for the consumer to get a hold of the pre-separated edges (32) of the layers and to separate the layers from each other by pulling them apart by hand.

Abstract: A communication network is comprised of a first, second, third and fourth controller node in line communication. Each controller node includes a microprocessor. Each microprocessor is programmable to respond to and generate data message bytes, each data byte having one start bit, eight data bits, one programmably settable bit and one stop bit. Each microprocessor is further programmable to respond only to a unique address-command data message byte from a message source node. The address-command byte is recognised because the settable bit is set. Each microprocessor is programmed to generate a reply message byte with the ninth bit not set and to then receive from the source node a message count byte followed uninterrupted by the data message bytes. Upon receiving a complete data message conforming to the received count of the count byte, the microprocessor then generates an acknowledgement byte.

Title: Vertical semiconductor laser with lateral electrode contact
Inventor: LURYI SERGEY
IPC: H01S5/042
Filed: 1990-12-05
Granted: 1995-04-18
Abstract: A vertical laser is typically formed by successive horizontal layers, epitaxially grown on a substrate, suitable for forming a bottom mirror, a bottomcladding layer, an active region, a top cladding layer, and a top mirror. In prior art, one of a pair of electrodes for enabling electrical pumping the laser--the "top"electrode--is attached to the top surface of the top mirror, whereby undesirably large amounts of heat are generated because of the relatively high impedance of the top mirror. To reduce this heat generation, the laser is redesigned to enable the top electrode to make lateral contact with the top cladding layer, whereby the impedance and hence the power loss are reduced.

Abstract: Circuitry and method for integrating current pulses, the circuitry including an integration amplifier having an integration capacitor located in its feedback loop.  The current pulse integrator also includes three current sources and four current switches.  A first current switch is located between a first current source and a second current source.  A second current switch is located between the output of the integration amplifier and the second current source.  A third current switch has one end connected to the first current source and the input to the integration amplifier, and the other end connected to the third current source.  A fourth current switch is connected between the output of the integration amplifier and the third current source.  Current passes through the integration capacitor in a first direction to charge the integration capacitor during a charge state of operation of the current pulse integrator. Current is prevented from passing through the integration capacitor in the first direction during at least one other state of operation of the current pulse integrator.  An output current from the integration amplifier during the charge state of operation is substantially equal to an output current from the integration amplifier during the other state or states of operation.

Granted: 1999-01-05
Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system.  A flow management screen station is rovided which divides an incoming unacceptable flow (F0) into two fractional flows (F1, F2), neither of which is acceptable for feeding to the digester.  One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow.  The other output flow is concentrated in undersized chips and particles compared to the incoming flow.  The output flows from the flow management screen are then fed to second and third screens (16, 14) which separate "overs" and "unders" from the respective flows to provide acceptable flows to the digester.

Abstract: Novel modified nylon-6 may be produced by using a combination of one or more dicarboxylic acids and triethylene glycol diamine and tetraethylene glycol diamine, but not a diethylene glycol diamine. A dicarboxylic acid/polyethylene glycol diamine salt may be reacted with .epsilon.-caprolactam to provide the modified nylon-6. The diamines have the formula NH2-(CH2CH2O)x-CH2CH2-NH2, where x ranges from 2 to 3.    Surprisingly, the suitable diamines include triethylene glycol diamine (x = 2; JEFFAMINE R EDR-148 Amine) and tetraethylene glycol diamine (x = 3;      JEFFAMINE R EDR-192 Amine), but not closely related bis-aminoethyl ether (x = 1; BAEE). Unexpectedly, BAEE, which only differs from JEFFAMINE EDR-148 Amine by one -(CH2CH2O)- group, did not give satisfactory product ~ the fibers were too weak. The resulting modified nylon-6 polymers of the invention, however, including fibers therefrom, have improved water absorbancy properties and greater flexibility.      Polyamide products with a wide range of water adsorbancies may be obtained by adjusting the amount of amide.
