Title: Enzymes having alpha-glycerol-3-phosphate oxidase activity, production and use thereof
IPC: C12N9/04
Filed: 1987-07-28
Abstract: An enzyme having  alpha -glycerol-3-phosphate oxidase activity characterised in that it has a Km of less then 2.5mM is disclosed, as is the production and use thereof. More particularly, such enzymes may be obtained from Propionibacterium species and may have Km values of less than 50 mu M, hence are advantageous for triglyceride/glycerol/ alpha -glycerol-3-phosphate determinations and test kits.
Patent EP-0265148-A3 (EP)
IPC: G06F3/02
Filed: 1987-10-13
Abstract: A bar code reader configuration and control system uses an 
interpreter routine in the operating system of the bar code 
reader and a menu with bar code tags encoded to invoke 
instructions which directly access and manipulate the system's 
memory. The instructions encoded in the bar code labels on 
the menu can access any memory address in the operating system 
to load any value at a given bit or byte location. By changing 
the values at the accessed memory locations, the menu tags 
perform two kinds of functions, configuring the operating 
characteristics of the bar code reader and controlling the 
operation of the reader. Other microprocessor controlled 
devices may accept a similar control system.

IPC: G06F12/08
Filed: 1988-03-25
Abstract: In a cache memory circuit which is operable in 
response to both an operand request and an operation 
code request which comprises an address tag memory 
portion (26), a valid tag memory portion (27), and a 
data memory portion (28), a dual port memory is used as 
each of the address tag memory portion, the valid memory 
portion, and the data memory portion to be accessed in 
response to both an input operand address and an input 
operation code address given through a pair of ports of 
the dual port memory on production of the operand and 
the operation code requests, respectively. Use of the

Title: Test composition device and method for the visual determination of hydrogen peroxide
IPC: C12Q1/28
Filed: 1988-08-30
Abstract: The invention involves the use of a multiple oxidative indicator system capable of generating different hues at different concentrations of hydrogen peroxide or at different concentrations of an analyte from which hydrogen peroxide is generated by means of the analyte specific oxidase. At least one component of the multiple oxidative indicator system changes from a particular hue to a different hue upon oxidation. A second indicator component is capable of being oxidized to a form having a hue which is visually distinct from the first indicator component in either of its forms. The test compositions of this invention are capable of generating visually distinct hues at different concentrations of hydrogen peroxide and can be used to generate a "rainbow" in an oxidative system.

Patent EP-0276954-A3 (EP)
IPC: C10G25/00
Filed: 1988-01-22
Abstract: A method of extruding clay and then treating the 
clay with acid to beneficiate the clay for increased 
capacity of filtration of oil-soluble colorant compounds 
from oil. The clay is first extruded through one or more 
die openings to align some of the clay platelets and to 
form the clay into cylindrical pellets. The extruded clay 
pellets are then acid treated, either before or after 
grinding, in an aqueous acid solution to form an acid 
slurry of the clay. The acid slurry of the clay is 
agitated for a sufficient time and temperature so that the 
acid reacts with a portion of the clay. Thereafter, the 
acid treated clay is separated from the acid solution; the 
clay is then washed to remove most of the acid solution 
from the clay, filtered and dried.

Title: Immobilizing particulate absorbents by conversion to hydrates
IPC: C08L101/00
Filed: 1988-09-20
Abstract: The invention provides absorbent compositions, a 
method for handling and immobilizing particulate 
absorbents and absorbent articles produced therefrom.  
     Absorbent materials such as cross-linked, 
water-soluble and water-swellable particulate polymers are 
immobilized and safely handled by adding thereto an 
aqueous liquid such as water or saline in amounts 
sufficient to form hydrates in which the water comprises 
from 20% to 80% by weight of the total hydrate. The 
hydrates may be extruded, sprinkled, or sprayed and can be 
incorporated into absorbent articles such as diaper and 
tampons by conventional means. The hydrates unexpectedly 
increase the total water absorbency of the absorbent on a 
dry basis.

Title: On-line web internal resistivity measuring apparatus
IPC: G01N27/07
Filed: 1989-03-09
Abstract: A web roller (20) is provided with at least two 
electrodes (70, 72) that are positioned parallel to 
each other on the roller surface end parallel to the 
longitudinal axis of the roller. Slip rings (50) 
provide individual electrical connections to the 
electrodes (70, 72). The electrodes (70, 72) are 
spaced apart a distance which permits both electrodes 
to be in contact with a web (40) of sheet material of 
the type having a conductive center (44) sandwiched 
between layers (42, 46) of insulating sheet. A 
position detector (80), positioned to detect the 
rotation of the roller, provides a pulse signal of a 
known magnitude to one of the electrodes (70), 
through a slip ring, when the electrodes are in 
contact with the web (40) of sheet material. A 
sensor (100) coupled to the other electrode (72), 
through a slip ring, receives the pulse signal after 
it has passed through the sheet material located 
between the two electrodes (70, 72). The magnitude 
of the received pulse is a function of the 
resistivity of the sheet material.

IPC: H01H35/02
Filed: 1989-03-10
Abstract: A motion detector (10) particularly adapted for use with the 
transmitter of a motor vehicle keyless entry system. The motion 
detector (10) causes the transmitter device carried by the 
user to transmit a coded signal when it is in motion, for 
example, as it is being carried by a user toward the vehicle. 
The motion detector includes a spool (12) surrounded by and 
electrically insulated from a shell (14). A ball (16) is 
positioned in the annular cavity around the spool (12). Asso­
ciated electronics are provided to sense a change in state 
of the motion detector as an indication of motion. Changes of 
state of the motion detector occur when the ball (16) moves 
into and out of direct contact with the spool (12) or shell (14) 
and further as the ball (16) rolls around the annular cavity 
while being supported by both the spool (12) and shell (14) 
caused by surface roughness of the interface surfaces.
