Title: Method for the immobilisation of waste material contaminated with organic chemical compounds
Inventor: HOOYKAAS CAREL W J
IPC: A62D101/26
Filed: 1993-09-17
Abstract: ABSTRACT OF THE DISCLOSURE            A method for the immobilisation of waste material contaminated with organic chemical compounds.      The application relates to a method for the immobilisation of organic contaminants in waste material, said method being directed in particular at the treatment of organochlorine and organophosphate pesticides which are difficult to decompose and which are contained in waste material, which material may be inadequately encapsulated by the known immobilisation processes. According to the invention, material contaminated with organic compounds is immobilised by mixing it with an inorganic hydraulic binder and, optionally, water and allowing the mixture to set, which method is characterised in that material contaminated with organic compounds which give off vaporous substances under alkaline conditions is immobilised by using an essentially calcium-free inorganic hydraulic binder, such as blast-furnace cement. Further, the waste material is, before the addition of said binder converted to a state saturated with water, and at least one salt of a transition metal, such as iron (III) sulphate, is added, followed by an oxidant, such as ammonium persulphate.
Patent CA-2107181-A1 (CA)
Inventor: TACHIKAWA YOSHIAKI
IPC: H01S5/10
Filed: 1993-09-28
Abstract: An optical device is presented which is useful for optical signal transmission and switching systems by multiplexing and demultiplexing optical signals in looped optical paths, consisting of a plurality of individual loop-back optical paths. The device is essentially a multi/demultiplexer having an arrayed waveguide grating disposed between a plurality of input sections and output sections which are joined by the plurality of individual loop-back optical paths.  Because the modulated signals are looped back into the same optical paths using the same devices, problems of mismatching performance introduced by using different optical devices are avoided.  The device processes individual optical signals of different wavelengths, minimizes splitting losses, and reduces noise components by producing narrow bandpass signals of high signal to noise ratio. Optical signal splitting and insertion, delay line memory and delay equalization circuits can all be handled by the same circuit configuration.  The device is simple in construction, reliable in performance and economical in production.

Title: Oligonucleotides derived from the sod family
Inventor: ZOLG WERNER
IPC: C12Q1/689
Filed: 1993-10-12
Abstract: The use of the superoxide dismutase (SOD; EC 1.15.1.1) gene system as a target for the detection and differentiation of pathogenic and non-pathogenic organisms including bacteria, fungi and protozoans is described. More particularly, there are described oligonucleotides derived from the SOD gene family which oligonucleotides are capable of hybridizing to a single-stranded nucleic acid sequence (target sequence) which is obtainable by amplifying and maturing a part of a gene coding for a superoxide dismutase (SOD) using a polymerase chain reaction (PCR) and a pair of primers, the first primer containing the sequence 5'-AGC TTC ACC ACA GCA AGC ACC A-3' (Seq. Id. No. 1; Z205) as priming sequence and the second primer containing the sequence 5'-TCG      G(T)CC CAG TTC ACG ACG(A,T) TTC CA-3' (Seq. Id. No. 2; Z212) as priming sequence. These oligonucleotides in the form of primers and probes are useful for the amplification and detection of target sequences derived from SOD genes, especially, from SOD genes of pathogenic and non-pathogenic organisms including bacteria (e.g. mycobacteria), fungi and protozoans.

IPC: A63B21/005
Filed: 1994-09-29
Abstract: A striding exercise device  includes a base having two elongated parallel tracks which curve upwardly in a constant radial arc, and two footskates which are rotatably  supported  on the  tracks  for  reciprocating movement thereon.  The radial arc generally corresponds to the natural swinging arc of a human leg as the leg pivots about the hip.  When the operator stands on the footskates and reciprocates the footskates back and forth along the upwardly curved tracks, the operator's torso is maintained in a stationary and balanced position over the base.   The reduction in torso movement substantially eliminates strain on the leg joints, particularly the knee and hip joints, caused by up and down movement of the torso  and  further  substantially  eliminates  back strain caused by reaching and bending at the waist.

Title: Modulated snubber driver for active snubber network
Inventor: GARCIA RICHARD R
IPC: H02M7/00
Filed: 1994-11-23
Abstract: A switching boost type voltage regulator includes a resonant snubber network connected in parallel with its FET power switch. The snubber includes a FET auxiliary switch that is connected and turned on in order to reduce the voltage across the FET power switch to a zero level at its turn-on transition. A driver circuit, driven by a voltage regulating pulse width modulation (PWM) pulse, initially turns on the FET auxiliary switch to reduce a voltage across the FET power switch and then turns on the FET power switch when the voltage across drops below a threshold level. The FET auxiliary switch is turned off when the FET power switch is turned on. A latch circuit insures the complimentary states of these two switches. The snubber circuit is disabled a near to zero voltage regardless of line and load levels and hence the power dissipation in the snubber is significantly reduced.
