Patent CA-2401810-A1 (CA)
Inventor: HAGELSTEIN PETER L
IPC: H02N3/00
Filed: 2001-03-06
Abstract: Solid state thermionic energy converter semiconductor diode implementation and method for conversion of thermal energy to electric energy, and electric energy to refrigeration. In embodiments of this invention a highly doped N region (16) can serve as an emitter region, from which carriers can be injected into a gap region. The gap region can be P-type, intrinsic, or moderately doped N-type (14). A hot ohmic contact (20) is connected to the N-type region. A cold ohmic contact (12) serves as a collector and is connected to the other side of the gap region. The cold ohmic contact has a recombination region formed between the cold ohmic contact and the gap region and a blocking compensation layer that reduces the thermoelectric back flow component. The heated emitter relative to the collector generates an EMF which drives current through a series load. The inventive principle works for hole conductivity, as well as for electrons.

Abstract: A portable apparatus for upconverting and downconverting the signals used to provide information interchange between terminals in terrestrial or satellite communications systems. The apparatus enables the upconversion and downconversion of electronic signals from baseband to the frequencies of the radio waves used for communications between the terminals. Such frequencies would typically be in the microwave range, i.e. from several GHz upwards. In the preferred embodiment the apparatus comprises two suitcase-sized units. One unit contains the apparatus for the modulation of electronic signals from base band frequencies to a chosen intermediate frequency and microprocessor-based circuitry to provide a centralized interface for overall monitoring and control of the apparatus. In addition, the first unit includes a built-in spectrum analyzer module which enables the visual spectral display of both transmit and receive signals. The second unit contains upconverters and downconverters for upconversion and downconversion of the selected intermediate frequencies to and from the desired air-link frequencies.

Abstract: This invention relates to intervertebral spacers (10, 30, 70, 90, 110, 120, 140 and 150) for use in orthopedic treatment of spinal defects. The intervertebral space is formed of a shaped memory polymer material. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.

Patent CA-2427605-A1 (CA)
Inventor: SCHULZ ROBERT
IPC: C01B6/24
Filed: 2001-10-02
Abstract: Disclosed is a method for rapidly carrying out a hydrogenation of a material capable of absorbing hydrogen. It was discovered that when a powder of a material capable of absorbing hydrogen is ground under a hydrogen pressure, not at room temperature but at a higher temperature (about 300~C in the case of magnesium) and in the presence of a hydrogenation activator such as graphite and optionally a catalyst, it is possible to transform completely the powder of this material into a hydride. Such a transformation is achieved in a period of time less than 1 hour whereas the known methods call for periods of time as much as 10 times longer. This is an unexpected result which gives rise to a considerable reduction in the cost of manufacture of an hydride, particularly MgH2.

Title: A process for preparing vegetable oil fractions rich in non-tocolic, high-melting, unsaponifiable matter
Inventor: ENKELUND JERGEN VALENTIN
IPC: A23L1/30
Filed: 2001-12-20
Abstract: A vegtable oil fraction rich in non-tocolic, high-melting, unsaponifiable matter is prepared by the following steps: A vegetable oil having a slip melting point of not more thatn 30~C and a content of unsaponifiable matter of at least 0.5% by weight is hydrongenated to fully saturate the fatty acids of the glycerides and to reach a slip melting point of at least 57~C. To the hydrongenated oil is added from 1 to 75% by weight of the unhydrogenated starting oil or another oil having a slip melting poing of not more than 30~C  in order to act as a carrier and vehicle for the unsaponifiable matter. Then, a solvent is added to the oil mixture in a ratio between oil and solvent from 1:2 to 1:20, and the mixture is heated to transparency. The oil/-solvent-mixture is cooled in one or more steps to a final temperature in the range from -35 to+30~C, and the precipitated high-melting fraction(s) is (are) filtered off. The filtrate is desolventised, leaving a fraction rich in unsaponifiable matter. By this process very high concentrations of in particular the non-tocolic, higher melting unsaponifiables can be achieved, and the composition of the glyceridic part of the enriched fraction can betailored to specific applications. Also, a novel blood cholesterol-lowering effect of the unsaponifiable constituents from shea butter has been found.

Title: Fastener collation strip having magazine rail-engaging members defining point-contact tip regions
Inventor: GUPTA HARISH C
IPC: B25C1/18
Filed: 2003-07-23
Abstract: A fastener collation strip has pairs of vertically aligned rail-engaging members or projections which have convergent sides disposed within at least two mutually orthogonal planes such that lower and upper tip regions of the rail-engaging members or projections define point-type contacts whereby the fastener collation strips are movably supported upon the rail members of the magazine section of the fastener-driving tool. As a result of the point-type contacts, frictional forces generated between the collation strips of fasteners and the rail members of the magazine section of the fastener-driving tool are effectively reduced as much as possible whereby the conveyance or transportation of the collation strips of fasteners through the magazine section of the fastener-driving tool is effectively facilitated so as to render the conveyance or transportation of the collation strips of fasteners through the magazine section of the fastener-driving tool as smooth as possible. In this manner, any tendency of the fastener collation strips to become retarded, "hung-up", or jammed within the magazine section of the fastener-driving tool is effectively prevented.

Filed: 2003-08-28
Abstract: A surveillance system having two specialized surveillance cameras with corresponding specialized illuminators is provided in a dual compartment container that eliminates internal light reflection problems by separating each camera and corresponding illuminator while combining each camera with an alternate illuminator, rendering the system more accurate, yet more compact and suited to unobtrusive placement. Considerable beat is generated by specialized illuminators, requiring a heat ink to preserve illuminator life expectancy and to prevent the adjacent cameras from being adversely affected by the heat. Another feature enabling the system to work in its compact form despite the heat from the illuminators in that protective case itself is adapted to be a heat sink for the illuminators.

Abstract: A phage genome is engineered to include a novel restriction site at one of two different positions. In a first embodiment, a restriction site is inserted into the phage genome I between the end of gene IV and the MOS hairpin which serves as a phage packaging signal for newly synthesized single strands of phage DNA. In a second embodiment, a restriction site is inserted into the phage genome after the MOS hairpin and prior to the minus strand origin. Once the phage genome is modified to contain the new restriction site, the vector can be engineered to be a "33" vector by inserting at the new restriction site a nucleotide sequence encoding at least a functional domain of pIII and at least a first cloning site for receiving a gene encoding a polypeptide to be displayed and, optionally a second cloning site for receiving a second gene encoding a polypeptide capable of dimerizing with the polypeptide to be displayed. In particularly useful embodiments, the novel vectors are engineered to produce phage particles that display antibodies.
