Patent CA-2235019-A1 (CA)
Title: A power-conserving linear broadband rf amplifier
Inventor: DAVIS PAUL COOPER
IPC: H04B1/40
Filed: 1998-04-16
Abstract: A power-conserving, linear and broadband RF amplifier, suitable for use at more than one band in the ultra-high frequency regions allotted to radiotelephone transceivers, employs an emitter-follower output transistor to deliver the nominal 1.0 milliwatt RF power to a single-ended load from a low voltage battery, typically 2.7 v. dc, without the use of output coupling transformers. The amplifier receives only a small differential input signal from the preceding mixer or multiplier stage having a typical peak-to-peak magnitude of 0.3 v. The differential input signal is applied to the emitters of a pair of transistors whose bases are interconnected, one transistor of which is diode-connected in a current-mirror configuration and the other of which is configured in a common-base connection with emitter degeneration. The signals are summed at the collector of the common-base transistor to deliver a substantial voltage swing, illustratively 1.7 volts peak to peak, which is large enough to drive the base of the emitter-follower output transistor without requiring the high standby current in the emitter-follower normally required to maintain an emitter-follower in class A operation.
Patent CA-2236033-A1 (CA)
Inventor: WULLIMANN FRANK
IPC: B66D5/04
Filed: 1995-12-04
Abstract: In order to increase the operational safety and to reduce the rope wear, hoisting/lowering apparatus comprise one or a combination of novel features: an adaptor (3) is provided in order to allow the attachment of accessories (50), preferably by insertion. Possible accessories are e.g. holders having a loop for the attachment of hooks, and single or multiple blocks for the formation of lifting blocks. Substantially, the adaptor is formed of a number of slot-shaped recesses which are transversely traversed by rod-shaped retaining elements (11,9). One of said retaining elements (9) is displaceably mounted in order to allow the attachment resp. detachment of an accessory (50). Another measure is to provide a rope stop (102) on the traction side. The rope (103) runs through the rope stop (102) and drives a knurled wheel (110). At a given rope speed, said wheel is coupled to a pivotable brake appendix (118) by means of a centrifugal coupling (113, 115). The rope (103) is then squeezed and blocked between said appendix (118) and a counterpart (108). A third measure consists in providing guiding rolls (36, 37) in order to ensure a spiral-shaped travel of the rope (103) which is free of crossings.

Title: Combined wire lead and interphase barrier for power switches
Inventor: SKOUG KENNETH N
IPC: H01H71/02
Filed: 1998-05-27
Abstract: Insulative guide members secured to an end face of switching apparatus between power terminals route electrical leads from attachment devices mounted inside the molded housing of the switch which exit the housing above the power terminals down between the power terminals toward the rear face thereby providing physical separation and electrical isolation between these leads and the power terminals and conductors connected to them. The insulative guide members are secured to the molded housing by a tongue-and-groove connection. The insulative guide members also form interface barriers with increased, oversurface distance between adjacent power terminals and conductors which can be further increased by longitudinal ribs on the guide members. In another configuration, the guide members can be secured to the confronting end faces of adjacent switching apparatus to provide interface isolation and to route leads from auxiliary switches from adjacent a front face of the switches toward a rear face.

Abstract: Fibrous cellulosic material is treated by applying an aqueous solution including a polycarboxylic acid crosslinking agent and an organic or inorganic sulphonic or sulfinic acid, particulalry p-toluene sulphonic acid, methane sulphonic acid and dodecyl benzene sulphonic acid, or salt particularly alkali metal, ammonium or alkaline earth metal salts, as an esterification catalyst, drying the fabric and heating it to promote crosslinking esterification of the polycarboxylic acid and the cellulose of the fibrous cellulosic material to give fabric with improved wrinkle and/or crease and/or shrink resistance and/or smooth drying properties. The method has the advantage that it does not use formaldehyde derivatives and thus the operation of the method and treated materials do not release formaldehyde during manufacture or use and the catalysts do not contain or use phosphorus containing compounds.

Patent CA-2251921-A1 (CA)
Title: Receiver with frequency offset correcting function
Inventor: MURAKAMI KEISHI
IPC: H04B7/01
Filed: 1997-03-04
Abstract: A receiver with frequency offset correcting function corrects distortion caused by interference between codes and a frequency offset in received signals. In order to correct the distorsion, a frequency offset correcting circuit (21) corrects the received signals based on an estimated frequency offset value. A first CIR estimating circuit (22) finds an estimated CIR value at a first position based on an already known training sequence in the corrected received signals. A second estimating circuit (24) finds another estimated CIR value at a second position which is different from the first position by updating the estimated CIR value at the first position as an initial value in accordance with an LMS algorithm based on the corrected received signals and a decision value outputted from an equalizer (13). A  phase deviation detecting circuit (15) calculates phase deviations based on the estimated CIR values at the first and second positions and an averaging circuit (26) averages the phase deviations and outputs the average phase deviation to a frequency offset correcting circuit (21) as an estimated frequency offset value.

Inventor: RUSSEK STEVEN LEE
IPC: C07C29/151
Filed: 1998-12-21
Abstract: Hydrocarbon feedstocks are converted into synthesis gas in a two-stage process comprising an initial steam reforming step followed by final conversion to synthesis gas in a mixed conducting membrane reactor. The steam reforming step converts a portion of the methane into synthesis gas and converts essentially all of the hydrocarbons heavier than methane into methane, hydrogen, and carbon oxides. The steam reforming step produces an intermediate feed stream containing methane, hydrogen, carbon oxides, and steam which can be processed without operating problems in a mixed conducting membrane reactor. The steam reforming and mixed conducting membrane reactors can be heat-integrated for maximum operating efficiency and produce synthesis gas with compositions suitable for a variety of final products. Synthesis gas produced by the methods of the invention is further reacted to yield liquid hydrocarbon or oxygenated organic liquid products.

Title: Disinfectant plastic sponge material
Inventor: SHANBROM EDWARD
IPC: C08L59/00
Filed: 1998-09-15
Abstract: A germicidal absorptive material for use in surgical packings, sanitary tampons and similar uses is provided by a sponge-like matrix of polyvinyl alcohol-acetal copolymer to which is tightly bound a germicidal disinfectant dye. Polyvinyl alcohol-acetal polymer shows exceptional avidity for a number of disinfectant dyes, both acidic and basic, such as methylene blue and gentian violet. Consequently, sponges of this material containing disinfectant dye release no dye to an aqueous solution. The material is generally a porous matrix that release no particles or fines into wounds or body orifices. Presence of bound disinfectant dye allows the sponge to inhibit bacterial growth in a number of different situations. Several common bacteria are killed by being incubated in the presence of an embodiment of the invention which contains both methylene blue and gentian violet.
