Abstract: Abstract Boar taint in individual animal bodies, preferably carcasses or parts thereof, can be detected by pre-paring an extract of a meat and/or fat sample from the body or part thereof, reacting said extract with a colour reagent, for which the colour intensity developed at certain wavelengths exhibit a statistical relationship with boar taint, determining the trans-mittance or absorbance  of the reacted extract at one or more such wavelengths, and inserting the recorded values in the said statistical relationship.         A high correlation has been found to exist between colour reaction and boar taint evaluation so that the transmittance or absorptance at wave lengths charac-teristic of the colour reaction gives a quantitative measure of boar taint intensity.  This has made it possible to determine threshold values which objectively define organoleptic inacceptable taint levels.  The method is fast and accurate and requires no extensive work; in addition it has been possible to automatize it so that it can be used directly in connection with slaughter lines in slaughterhouses for industrial control and sorting of individual carcasses.

Abstract: ABSTRACT OF THE DISCLOSURE           The radar trigger and pretrigger generator determines the inherent component time delay through the radar modulator and transmitter during a first cycle of operation.  During the next cycle of operation a pre-trigger pulse is generated after a time corresponding to the previously measured delay and a trigger pulse is generated after a time corresponding to an operator selectable delay.  The trigger pulse is used to trigger the radar modulator, which in effect, permits the operator to control the elapsed time between pretrigger pulse and transmitter firing in a fashion which is completely  independent of circuit delay variances through the radar modulator and transmitter.

Abstract: ABSTRACT        Penicillin sulfoxide esters are reacted with an iso-cyanate to produce the corresponding (substituted)-2-carbamoyl-oxymethylpenam, the corresponding (substituted)-3-carbamoyl-oxycepham or the corresponding 3-methylcephem.  The 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephams) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-methylcephams.  The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.  Novel penams and cephams provided by the present invention (after removal of the carboxyl-protecting group to produce the free acid) are active against various Gram-positive and Gram-negative organisms and, accordingly, are useful antibacterial agents for the treatment of diseases caused by such organisms in animals, including man.

Title: Radio paging receiver having display control means
Inventor: TSUNODA KAZUYUKI
IPC: H04W88/02
Filed: 1983-02-11
Granted: 1986-06-17
Abstract: ABSTRACT A radio paging receiver is described. Typically, such receivers generate an alert tone and store display information or a message when a selective calling signal is received. One problem with prior art devices is that when the alert tone is manually switched off by the user the message displayed is then also lost, either immediately or after a preset delay. The invention provides the improvement in that the manual alert tone reset switch can be depressed without erasing the message which is retained indef-initely while the switch is maintained depressed. Only on releasing the switch is the display reset either immediately or after a preset delay. This gives better control to the user and assists in preventing inadvertent loss of message.
