Title: Food service cart with individually removable heaters
Inventor: WIMPEE JULIA T
IPC: A47B31/02
Filed: 1990-08-06
Abstract: A heating system for use in a food service cart (12) includes a plurality of vertically spaced tray supports (30) attached to the cart (12) and a plurality of heaters attached to the cart at a plurality of vertically spaced locations in alignment with shelf locations for heating foods carried on service trays and supported by the tray supports. The heaters are individually removable from the cart. A thermostatic control controls the power supplied by each respective heater during a predetermined time period and includes a sensing mechanism for sensing temperature and a power adjusting mechanism for adjusting the power supplied by the heater.  The sensing mechanism senses temperature over a predetermined range having upper and lower temperature limits, and the power adjusting mechanism reduces the power at which the heater operates to a lower power level when the sensing mechanism senses the upper temperature limit and increases the power at which the heater operates to a higher power level above the lower power level when the sensing mechanism senses temperature at or below the lower temperature limit. Food is rethermalized by a method that continuously applies power through a heater over the predetermined time period, alternately at the high and low power levels.

Inventor: BARBOUR R JAMES
IPC: G01N33/46
Filed: 1992-05-20
Abstract: The presence of decay is determined in wood by testing a sample.  The wood tested may be standing timber, cut timber or when coated in building structures. The testing occurs in very short time intervals so that tests can be carried out on timber in mills and the like. The method of testing includes heating a portion of a wood sample at a temperature in the range of about 220 to 350°C to evaporate analytes from the wood, conveying the analytes in a sample gas flow into an ionizing chamber of an ion  mobility spectrometer detector, ionizing the analytes within the ionizing chamber at a temperature in the range of about 220 to 350°C, generating an ion drift time signature in the detector, and comparing the signature with predetermined signatures representing decay in wood.

Patent CA-2078965-A1 (CA)
Title: Pour Spout
Inventor: MITCHELL ROBERT K
IPC: B65D47/32
Filed: 1992-09-23
Abstract: A pour spout for pouring a fluid, such as fuel, by gravity from a container to a tank.  The spout includes a conduit having one end connected to the fuel container and having a second end to be positioned within the neck of the tank.  A sleeve is mounted for sliding movement within the conduit and the outer end of the sleeve carries a closure which closes off the discharge end of the conduit.  A vent tube is disposed within the conduit and has an inlet end which is adapted to communicate with the fuel tank when the closure is in the open position.  A check valve is mounted within the vent tube and permits the flow of fuel vapor and air from the tank through the tube to the container, but prevents flow of fuel in the opposite direction.  An annular collar is mounted on the conduit and with the collar engaged with the neck of the fuel tank, a downward force applied through the container on the sleeve will open the closure to admit fuel through the conduit to the tank.  The collar is adjustably mounted along the length of the fluid conduit to accommodate tank necks of different configurations.  The closure carries a rotatable tab which encloses the inlet of the vent tube when the closure is in the closed position to prevent foreign material from entering the vent tube, but permits limited vapor and air flow to eliminate a buildup of pressure or vacuum in the fuel container.  By rotating the tab, the tab can be brought into sealing engagement with the inlet of the vent tube to prevent vapor or liquid flow therethrough.

Title: Method and apparatus for automatically identifying a program including a sound signal
Inventor: FARDEAU MICHEL
IPC: H04B17/00
Filed: 1992-09-28
Abstract: A method and apparatus for automatically identifying a program broadcast by a radio station or by a television channel, or recorded on a medium, by adding an inaudible encoded message to the sound signal of the program, the message identifying the broadcasting channel or station, the program, and/or the exact date. In one embodiment the sound signal is transmitted via an analog-to-digital converter to a data processor enabling frequency components to be split up, enabling the energy in some of the frequency components to be altered in a predetermined manner to form an encoded identification message, and with the output from the data processor being connected via a digital-to-analog converter to an audio output for broadcasting or recording the sound signal. In another embodiment, an analog bandpass filter is employed to separate a band of frequencies from the sound signal so that energy in the separated band may be thus altered to encode the sound signal. The invention is particularly applicable to measuring the audiences of programs that are broadcast by radio or television, or that are recorded.

Title: Hood for fireplace
Inventor: RIEGER HEINZ H
IPC: F24B1/18
Filed: 1992-11-12
Abstract: A fireplace has a manifold positioned between a combustion chamber and a flue.  The manifold has a pair of inlets to supply dilution air to the flue, one extending from a front face of the fireplace, and the other from a rearward location.  A baffle extends across the outlet of the manifold to prevent direct communication between the combustion chamber and flue. The inlet at the front face enables the flow of dilution air to be checked with the fireplace installed without having to accomodate the full flow of dilution air.  The baffle prevents downdrafts from adversely affecting the combustion in the combustion chamber.

Abstract: ABSTRACT     In a process for a basis:  for a beverage, a yogurt, or cheese; which is comprised of an extraction from almonds or other nuts through heat in a mixture of milk and the option of honey (or other sweetener).  It is a new product  even  though  comprised of  traditional  ingredients  and methods.   The recipe is as follows:  1 part, or 1 cup, of nuts are chopped in a blender or food processor and added to 4 parts, or 4 cups, of milk and 3 teaspoons of honey in a double boiler (or other cooking method).  The solution is then covered and cooked for 45 minutes; these are suggested measures and times, for in experimenting substituting 1/2 part of nuts instead of 1 part of nuts that the beverage was too weak. However 1 1/2 parts of nuts  cooked to the above directions was ideal for the yogurt but far too strong for a beverage. Please note that honey or any sweetener is optional for cheeses. Once cooked the solution is then passed through a strainer to remove the nuts and is ready to drink, or once cooled to have live yogurt cultures added, or cheese cultures added, and be packaged when ready.   The residue of nutmeats can be placed at the bottom of the yogurt cup, or dispersed throughout the yogurt or cheese, or discarded.     *These are suggested measures and times.

Title: Viral defective vaccine produced by transcomplementing cell line
Inventor: INGLIS STEPHEN C
IPC: A61K39/245
Filed: 1991-09-23
Abstract: A mutant virus for use as a vaccine, wherein the genome of the virus is defective in respect of a gene essential for the pro-duction of infectious virus. In one aspect the mutant virus is capable of protecting a susceptible species immunized therewith against infection by the corresponding wild-type virus. In another aspect, the mutant virus acts as a vector for an immunogenic protein derived from a pathogen and which is encoded by foreign DNA  incorporated in the mutant virus. The mutant virus can be produced in a recombinant host cell which expresses a gene complementing the defect. The mutant virus is preferably infec-tious for the host to be protected, but the defective gene allows expression in the infected host of at least some of the viral genes, which can provoke a cell-mediated immune response.
