Patent CA-2020239-A1 (CA)
Inventor: ENG KAI Y
IPC: H04L12/56
Filed: 1990-06-29
Abstract: This invention is an inventive N input by L output interconnect fabric. In operation, packets comprising an information field and an address are received at the N inputs to the interconnect fabric, and the address in each packet is mapped to a group of outputs, rather than to any particular output. Each packet is then routed to any available one of the interconnect fabric outputs associated with the group to which the packet is mapped. If a number of packets destined for the same group simultaneously arrive at the interconnect fabric inputs and the group to which they are all destined does not comprise enough outputs to accept them, then all packets in excess of the number that the destined group can accept are simply discarded. The probability of lost packets due to such discarded packets is acceptably small. In one exemplary embodiment, the invention can be utilized to build arbitrarily large packet switches.

Title: Disposable collector and container
Inventor: BARDES DALE L
IPC: B65D85/00
Filed: 1990-07-06
Abstract: A disposable device for the manual collection and containment  of  small  amounts  of  material  without direct  manual  contact.   The  device  comprises  an elongated  bag  of  flexible,  moisture-proof  material having an open end and a closed end.  The bag is so sized as to comfortably receive the user's hand.  The closed end of the bag is two ply with a thin layer of air  therebetween  for  puncture  resistance  and  is gusseted to have a "W"-shape in cross-section.  This gusseting  provides  two  interior  pockets  for  the receipt   of  the   user's   fingers   and   thumb, respectively, and an intermediate exterior pocket to receive the collected material which is picked up by opposing forces applied thereto by the user's fingers and  thumb.   Once  the  material  to  be  collected  is engaged in the intermediate exterior pocket, the user employs  his  free  hand  to  strip  the  bag  from  his occupied hand by engaging  the  open end  of  the bag with his free hand and pulling it forwardly of his occupied  hand,   turning  the  bag  inside-out  and completely  enclosing  the  collected  material.   The elongated body of the bag can be tied in a knot or provided with an appropriate tying or sealing means.

Abstract: The present invention relates to a process for the preparation of alcohols by reacting organic carbonyl compounds with hydrogen at increased temperature and optionally increased pressure, in two steps, where, in the first step, the gaseous carbonyl compounds are passed to a copper-containing catalyst and, in the second step, the liquid carbonyl compounds are passed to a nickel-containing catalyst. The carbonyl compounds are reacted in the first step to an extent of 80 to 99.5% of theory and in the second step by means of a support catalyst which contains nickel, aluminium oxide and zirconium dioxide. The carbonyl compounds used are aldehydes and their derivatives, in particular aliphatic unsaturated and saturated aldehydes.

Patent CA-2033796-A1 (CA)
IPC: H04B5/00
Filed: 1991-01-08
Abstract: A regenerative RF bi-directional communications system is provided for establishing RF coverage within a RF block tunnel area.  The system uses a plurality of cascaded amplifier stages for periodically regenerating signals which are transmitted and received along a series of radiating cable length which link base station transceivers to hand-held or like mobile communication units. An intermediate frequency distribution system is used so that the required level of amplification is achieved through the several cascaded amplifier stages at the level of low-power IF signals generated from the original RF signals in conjunction with the appropriate oscillator and pilot signals. The IF distribution system restricts the cascading effect occurring due to the plurality of cascaded amplifier stages on the relatively low-power IF signals, thereby producing a negligible amount of intermodulation.

Title: Method for the sheeting of deep trenches
Inventor: HESS WILHELM
IPC: E02D5/02
Filed: 1992-04-07
Abstract: A method for sheeting deep trenches by means of supporting frames mountable lengthwise the trench at equal distances. The supporting frames comprise two parallel supporting elements and a rigid frame movable in the longitudinal direction of the supporting elements and connecting and keeping them spaced-apart, and large sheeting panels insertable into guide channels of the supporting elements. The supporting frames and the sheeting panels are pressed or lowered into the trench, following the direction of excavation. The rigid frame is movably guided between a lower stop and an upper stop along the supporting elements, whereby the lower stop is positioned at the required shovel clearance approximately 1 to 1.50 m from the end of the supporting element, and the upper stop is positioned at a distance from the lower stop, which distance corresponds to the height of the rigid frame, e.g., 1.75 m, and to an admissible support advance, e.g., 0.5 m. Once the supporting frame has been installed and lowered to a level at which the upper edge of the rigid frame is on the level of the trench's edge, the upper stops are removed, a second rigid frame is inserted into the supporting elements of the supporting frame, and the upper stops are fastened to the supporting elements at a distance above the second rigid frame. After lowering the supporting frame by another depth equal to a rigid frame, the upper stops are removed and, if necessary, a third rigid frame is inserted into the supporting elements of the supporting frame. The rigid frames are interconnected with each other to permit dismantling of the supporting frame.
