Abstract: A food preparation apparatus including a cooking 
chamber (12) having a pair of openings (22,24) in two 
opposite facing walls (26,27) thereof. A conveyor 
extends through the side wall openings (22,24) in the

Title: Method of quantitative analysis of hydrogen peroxide and reagent therefor
IPC: C12Q1/26
Filed: 1988-10-24
Abstract: A method for quantitative analysis of hydrogen peroxide at a high precision is disclosed. The method comprises reacting a divalent cobalt compound with hydrogen peroxide in the presence of peroxidase or a substance similar to peroxidase to produce a trivalent cobalt compound, reacting the trivalent cobalt compound thus produced with a trivalent cobalt indicator to produced a colored complex, and subjecting the colored complex to colorimetric quantitative analysis. The method enables various enzymatic activities producing hydrogen peroxide by the reaction with substrates as well as the amount or activity of substances involving the known enzymatic reactions linked with such enzymatic reactions, of enzymes and coenzymes, to be quantitatively determined very easily at a high sensitivity at a wavelength of above 600 nm without the interference of hemoglobin, bilirubin, or turbidity.

Title: Swivel-up type dispensing package
IPC: A45D40/04
Filed: 1988-10-07
Abstract: A dispensing package which automatically relieves residual pressure on a cream product and dispenses this product in incremental doses is disclosed. The package uses a feed screw (31) to drive an elevator (27) which impels the cream product in a unidirectional manner. The drive of the feed screw (31) is superimposed with reciprocatory motion caused by internal cams which retract the elevator (27). By intermittently retracting the elevator (27) a suitable distance, discrete amounts of the product are dispensed for each cycle and the residual pressure on the product is relieved, preventing it from weeping onto the applicating surface (22) of the dispenser. The dispensing package is well suited to contain and dispense cream deodorants and antiperspirants.

Abstract: In a cellular data transmission system non-interfering digital 
communication channels are added to existing analog or digital 
voice communications channels in the system by utilising 
frequency space between channels made possible by the

Abstract: A second bar code such as an add-on code which comprises 
only a character bar and is added to the side of the first 
bar code such as UPC, EAN and JAN and having a center bar 
and a guard bar can be correctly read out. When the scanning 
is made from the first bar code side to the second bar 
code side, a write address produces, when the right guard 
bar of the first bar code is recognized, a signal which 
is used to access the data of the second bar code. Conversely, 
where the scanning is made from the second bar code side 
to the first bar code side, the write address produces, 
when the center bar of the first bar code is recognized, 
a signal which is used to access the second bar code after 
subjecting to some arithmethic operation. Therefore, the 
first bar code can be clearly distinguished from the second 
bar code which is different in the bar code system and 
the second bar code can be correctly read out.
