Patent CA-2122430-A1 (CA)
Title: Ambient condition detector with high intensity strobe light
Inventor: SWIEBODA MICHAEL A
IPC: G08B5/36
Filed: 1994-04-28
Abstract: A drive circuit for use with an ambient condition detector limits heat dissipation and associated temperature rises in the presence of varying RMS values of an applied AC signal. The drive circuit includes a voltage doubler with a current regulator located between first and second storage elements. In the presence of a sensed ambient condition, which exceeds a predetermined threshold the regulator is enabled permitting one of the storage elements to be charged to a voltage on the order of twice the peak value of the applied AC voltage. A digital timer is used to trigger a flashable visual indicator from the stored DC voltage. The regulator provides a substantially constant DC voltage to the visual indicator in the presence of a varying AC line voltage.

Title: Cargo Tiedown
Inventor: DAVIS JIM B
IPC: B60P7/08
Filed: 1994-05-25
Abstract: A cargo tiedown permanently installable to the bed or floor of the cargo area of a pickup truck, trailer, or other vehicle, provides security for relatively thin, flat or narrow articles (e.g., sheet material, pipe, elongate extrusions, etc.) carried on the bed of floor. The tiedowns are preferably installed in pairs, on opposite sides of the floor or bed. The tiedown is monolithically formed of a series of base portions with tiedown loops or bridges extending therebetween. Each of the base portions include at least one fastener passage providing for securing the tiedown to the vehicle cargo floor. Each tiedown may include two or more tiedown loops or bridges, providing for the securing of a rope or other retainer laterally across the floor or bed. The base portions may be hollow, in order to save weight and material, and may include bosses extending through the hollow base portions for greater strength. The device is formed to eliminate sharp edges, in order to better protect any articles with which it might come in contact. Preferably, the fastener holes are countersunk for use with flat head screws, in order to eliminate any protrusion of screw heads from the upper surfaces of the base portions. The main body of the device may be formed of a variety of materials, such as aluminum or steel, either standard or stainless, or even plastic.

Patent CA-2127530-A1 (CA)
Title: Metal complexes of water soluble texaphyrins
Inventor: SESSLER JONATHAN L
IPC: C07H17/02
Filed: 1993-01-07
Abstract: The present invention involves water soluble hydroxy-substituted texaphyrins retaining lipophilicity, of formula (I) wherein: M is H, a divalent or a trivalent metal cation; R1, R2, R3, R4 and R5 are independently H, OH, C n H(2n+1)O y or OC n H(2n+1)O y where at least one of R1, R2, R3, R4 and R5 has at least one hydroxy substituent; the molecular weight of any one of R1, R2, R3, R4 or R5 is less than or equal to about 1000 daltons; n is a positive integer or zero; y is zero or a positive integer less than or equal to (2n+ 1); and N is an integer between -20 and +2. These expanded porphyrin-like macrocycles are efficient chelators of divalent and trivalent metal ions. Various metal (e.g., transition, main group, and lanthanide) complexes of the hydroxy-substituted texaphyrin derivatives of the present invention have unusual water solubility and stability. They absorb light strongly in a physiologically important region (i.e. 690-880 nm). They have enhanced relaxivity and therefore are useful in magnetic resonance imaging. They form long-lived triplet states in high yield and act as photosensitizers for the generation of singlet oxygen. Thus, they are useful for inactivation or destruction of human immunodeficiency virus (HIV-1), mononuclear or other cells infected with such virus as well as tumor cells. They are water soluble, yet they retain sufficient lipophilicity so as to have greater affinity for lipid rich areas such as atheroma and tumors. They may be used for magnetic resonance imaging followed by photodynamic tumor therapy in the treatment of atheroma and tumors. These properties, coupled with their high chemical stability and appreciable solubility in water, add to their usefulness.

Abstract: A PREASSEMBLED TRAY/SHROUD CONTAINER     ABSTRACT OF THE DISCLOSURE    A tray/shroud  shipping container which  is convertible to  a display container upon removal  of the shroud.   The container  is preassembled  before  being  filled  with  packaged  goods  from  two separate   blanks which are joined together to form the container. The container is made from a tray blank for forming the tray and a shroud blank for forming the shroud.  The shroud telescopes within the tray and is releasably secured within the tray and covers and protects the packaged goods.  The container includes two diagonally opposing  vertical  fold  lines  which  comprise  two  substantially parallel lines of weakness.  The lines of weakness of each pair are spaced apart by distances least as great as the thickness of the container so that the container can be folded along the lines of weakness  thereby  collapsing  the  container  to  a  generally  flat condition.

Title: Electronic power converter circuit arrangement and method for driving same
Inventor: GERSTER CHRISTIAN
IPC: H02M1/088
Filed: 1994-09-01
Abstract: A method and a device for driving a series circuit of power semicondutor switches (2) are specified. In this case, the voltage loading of the individual switches of the series circuit is balanced by providing that the voltage (Ucel ... Ucen) across each switch of the series circuit is measured as the controlled variable, and that this measured voltage is used to vary the switching instants in such a way that the voltage loading during switching is essentially equal for all the switches. In addition, the level of the control voltage (Ugeoff1 ... Ugeoffn) in the blocking state can be influenced with the aid of the measured voltage in such a way that the blocking voltages of the switches are essentially equal. The advantage of the invention is to be seen in that the voltage loading of the individual semiconductors can be balanced not only during switching, but also in the blocking state. In addition, the control also balances influences of parameter differences and parameter changes, as well as influences of the circuit. As a result, the switches can be optimally utilized in terms both of power and of frequency.

Title: Glazing unit and a method for its manufacture
Inventor: CHINZI CALOGERO
IPC: B32B17/10
Filed: 1994-11-21
Abstract: A glazing unit is described comprising a composite glazing panel having a pair of vitreous sheets (21, 22) with an intervening layer (23) of polymeric material sandwiched therebetween. The polymeric material layer has viscoelastic properties such that the critical frequency of coincidence (or the lower or lowest critical frequency of coincidence if there is more than one) of the panel ["the coincidence frequency (.PHI.p) of the panel"] is greater than the critical frequency of coincidence of a notional monolithic vitreous sheet ["the coincidence frequency (.PHI.m) of the equivalent monolith"] which monolithic sheet is of the same shape and area as the panel and has a mass equal to the total mass of vitreous material in the panel. An adhesive material (29, 30) is in contact with each vitreous sheet. The adhesive material exhibits, at 20°C, an elongation of not more than 12.5% when subjected to a tensile stress of 0.1 MPa, as measured according to ISO 8339. There is such adhesive material in contact with an outer face of at least one of said sheets (22), at a marginal portion thereof. The arrangement enables more secure fixing of the composite panel in the unit.       (Fig. 2)

Title: Flavor enhancing composition containing colloidal silica and method for its preparation and use
Inventor: HOLCOMB ROBERT R
IPC: A23L21/10
Filed: 1993-07-09
Abstract: Flavor enhancing compositions include an aqueous mixture containing charged colloidal silica of preferable 10-100 angstrom particle size. The colloidal silica acts synergistically with other flavor inducing agents. The compositions enhance flavor, tenderize meats, aid in the formation of a stable crust on breaded fired foods, and impart improved body, consistency, and flavor in soups, dressings, and beverages. The colloidal silica may be generated by circulating an aqueous solution containing colloidal silica particles, preferably in about 3 to about 4 molar NaOH with citric acid or a salt thereof also present, through a magnetic field so that the silica particles cut through the field to generate a charge thereon. The solution is preferably circulated through a helical coil (21) in a magnetic field created by a quadrilateral arrangement of magnets (34, 35, 36 and 37), and then passes through an area of magnetic void (33) between the magnets. The solution is diluted and titrated as it is circulated.
