Title: Paper coating composition
Inventor: HAHN KARL
IPC: C09D133/04
Filed: 1992-12-31
Abstract: ABSTRACT           A paper coating composition comprising an aqueous plastic dispersion prepared from 15 to 85% by weight of a C8 to C12 monovinyl aromatic compound, 14 to 84% by weight of a plasti-cising component selected from the group consisting of C4 to C6 acyclic, conjugated diolefines and C4 to C6 alkyl (meth)acrylates, 0.5 to 10% by weight of a C3 to C6 .alpha.,.beta.-monoethylenically unsaturated carboxylic acid and 0.25 to 15% of .alpha.-methyleneglutaronitrile as binder.  The last monomer is essential in that it replaces acrylo-nitrile, usually used in this kind of coating compositions, which is acknowledged to be a hazardous material.  Papers coated with the coating composition according to the invention show a good wet pick resistance and good colour uptake resulting in an improved printability.

Title: A method and apparatus for manufacturing a flexible abrasive hone
Inventor: FOWLIE ROBERT G
IPC: B24D3/28
Filed: 1993-01-22
Abstract: The method and apparatus enables enlarged multi-phase globules 65 to be firmly and non-detachably mounted on tip end portions of flexible hone bristles 55, By one method aspect, a first coating 90 of an at least semi-liquid, controllably hardenable adhesive matrix material 85a is applied to each tip end portion 60 of the bristles in a desired lamina thickness, as determined in part by the natural retention characteristics of the coated bristle tip end portions 60. each first coating 90 is fixed and immobilized relative to its bristle tip end portion 60 whereby to substantially inhibit and prevent displacement of excess liquid, or partly liquid portions of said matrix material 85a from occurring on, and along, the bristle tip end portion 60. A quantity of usually dry particles of finely-divided abrasive material 115 is brought into mating and bonding contact with said coating 90 while it is still in at least partially semi-liquid form, thereby causing the effective picking-up of abrasive particles by said matrix material and the effective intermixing thereof into an effective two-phase, composite abrasive-matrix material 90 + 115. Said bristle tip end portions 60, carrying said coating are then subjected to the required physical conditions needed for hardening and curing said composite abrasive-matrix material on said bristle tip end portions, to a desired extent. The method permits quick and efficient mass production of flexible abrasive hones. Figs.1 and 8.

Abstract: ABSTRACT OF THE DISCLOSURE    An electronic clinical thermometer which detects temperature of a measured part and determines equilibrium temperature by prediction calculation based on change of the detected temperature.  One of classified temperature rise data groups is selected based on the change of the detected temperature and one of prediction equations and a set of prediction parameters are designated in accordance with the selected data group.  The selected data group can be changed based on change of the detected temperature in a predetermined period after the selection of data group.          Further, reliability of the measurement is judged based on the detected or predicted temperature and the predicted value can be corrected if the reliability is insufficient.

Title: Apparatus for measuring thickness of metals on a rolling mill
Inventor: KRAYBILL JOHN
IPC: G01B15/02
Filed: 1993-07-08
Abstract: ABSTRACT   An apparatus and method for gauging the thickness of a moving sheet material, typically a metal, which has a variable alloy composition over its length. This is accomplished by measuring the spectral energy of a radiation beam which has not been absorbed by the material and passed perpendicularly through the material by utilizing a length absorption filter radiation detector.The length absorption filter spectrally filters the radiation into separate wavelengths and measures the intensity of these wavelengths. Electrical outputs representing these measured values is output to a processor which then determines the thickness of the material based on the transmission ratios measured for each measured energy band and the absorption coefficients of the elements in the material. This result is then used to control the rolling mill to provide real-time on-line feedback.

Title: Electronic combination lock with time delay feature to control opening
Inventor: DAWSON GERALD L
IPC: G07C9/00
Filed: 1993-09-07
Abstract: ELECTRONIC COMBINATION LOCK WITH TIME DELAY               FEATURE TO CONTROL OPENING                 Abstract of the Disclosure An electronic lock is provided with a timer capability to delay the operability of the lock for a preset period of time following the proper and correct entry of a combination into the lock.  This delay prevents the lock from opening until both the time has expired and an access code entered following the time delay. If the access code entered after the time delay is incorrect, a further time delay or penalty delay will prevent the operator from an immediate attempt to enter a second access code.  If a second access code is entered after the penalty delay and also is incorrect, the entire lock operation resets and the operation of the lock must begin with the re-entry of the correct combination.  The entry of a combination to operate the lock which is offset by a predetermined value from the authorized combination will indicate by alarm at a remote monitoring center that the lock is being opened and may be opened under duress to the operator.  The combination of the time delay as well as the entry of the alarm combination provide an opportunity for the monitoring center personnel either to react or to notify the appropriate security/law enforcement personnel to respond to a potential robbery.

Abstract: ABSTRACT OF THE DISCLOSURE A modified method of playing the card game "Twenty-One" or "Blackjack", wherein a common card, referred to as the "Fast Action Card", is counted in the hands of each of the players and the dealer.  To begin a hand, each player makes an ante wager.  Then the dealer deals each player and the dealer one card, preferably all face up, and deals the fast action card face down.   The players then each have an option to make an additional wager, referred to as the "even money" wager.   Each player also has the option to make an insurance wager if the dealer's first card is an ace.  Then the fast action card is turned face up and each of the players has the option to double down, based upon the combination of his first card and the fast action card, and to make a double down wager,  if his hand qualifies.   The play then proceeds in accordance with the conventional manner of play of Twenty-One.  Winnings are paid and losing wagers are collected by the dealer.

Title: Peptides useful as internal standards for microsequencing and methods for their use
Inventor: PARMELEE DAVID C
IPC: C07K14/47
Filed: 1993-07-23
Abstract: The present invention provides a novel internal standard for amino acid sequencing which contains a peptide consisting of unnatural amino acid res-idues, such as ornithine, norvaline, norleucine and .alpha.-aminobutyric acid, that is capable of being sequenced si-multaneously with an unknown pep-tide or protein without interfering with the analysis. The internal standard peptide has an amino acid sequence containing at least two different unnat-ural amino acid residues having reten-tion times distinct from the corre-sponding retention times for natural amino acid residues. Information de-rived from the sequencing of the inter-nal standard allows determination of repetitive yield, lag, N-terminal block-age and discrimination between blank cycles caused by missed injection and blank cycles caused by faulty delivery of chemicals during the sequencer reactions. The present invention further provides novel synthetic control peptides containing from about 3 to 100 natural amino acid residues that are designed for use in monitoring the proper operation of amino acid se-quencers and to monitor peptide or protein cleavage reactions. The control peptide, or mixture of control peptides, are designed to obtain data for many or all common, uncommon and difficult to measure amino acids within 15 sequencer cycles and to pro-vide cleavage sites for at least 4 different amino acide cleavage reactants.
