Title: Dna molecule encoding freezing tolerance proteins in gramineae
Inventor: SARHAN FATHEY
IPC: C12N15/82
Filed: 1993-08-16
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to three novel genes which  have  been  isolated  from  cold-tolerant  wheat species and which are induced by low temperature.  The first gene, Wcs19, is preferentially expressed in green leaf tissues of tolerant gramineae species and requires both light and low temperature for maximal induction.          The  second  gene,  Wcs120,  is  induced  only  by  low temperature.   Different from the protein encoded by Wcs19,  the protein  encoded by Wcs120  contains  two repeated domains that are highly conserved among RAB          (rice abscisic acid-induced) and dehydrin families and appears to be light-independent.   The Wcs120 protein does not however contain a serine-rich sequence present in RAB and dehydrin families.   Finally,  the present invention also relates to a third gene, Wcor410, also induced by low temperature as well as water stress and, to a lesser extent, by ABA.  Its expression is light-independent.  The protein encoded by this gene contains a  serine-rich  stretch  as  found  in  several  drought induced proteins.

Patent CA-2108922-A1 (CA)
Title: A disk player
Inventor: SHIMIZU HIDETOSHI
IPC: G11B19/28
Filed: 1993-10-21
Abstract: The present invention provides a disk player, which is capable of changing the playing linear velocity by a multiple stages to shorten the reading time.  The disk player includes the conventional motor, and an optical pick-up.  A first clock section generates master clock signals,  for changing the frequency of the master clock signals by multiple stages, as well as an oscillating circuit for generating standard clock signals.    First  and  second divider  circuits  divide  the standard clock signals and generate first and second divided signals.  A phase comparing circuit compares the phases of the first and second divided signals and generates phase-deviation signals which correspond to the phase deviation thereof.  A processing   section  generates   setting   signals,   which respectively define the dividing ratio of the first and second divider circuits.   A second clock section generates second clock signals whose frequency is equal to the frequency of synchronizing signals.  A comparing section compares mutual frequency and phase of the master clock signals and the second signals and generates deviation signals whose voltage level corresponds to the differences of the frequency and the phase thereof.  A drive section sends drive signals, whose voltage level changes according to voltage changes of the deviation signals, to the motor.  Thus, the drive section controls the motor so as to synchronize the frequency and the phase of the second clock signals with those of the master clock signals.

Title: Use of oxidase inhibitor with dextromethorphan to treat intractable coughing and dermatitis
Inventor: SMITH RICHARD A
IPC: A61K31/47
Filed: 1994-01-26
Abstract: USE OF OXIDASE INHIBITOR WITH DEXTROMETHORPHAN  TO TREAT INTRACTABLE COUGHING AND DERMATITIS                           ABSTRACT      This invention discloses a method for increasing the effectiveness of dextromethorphan (DM) in treating either severe coughing or dermatitis which do not respond to other drug treatments. This method involves the administration, to a patient who is an extensive metabolizer of dextromethorphan and who is suffering from severe coughing or dermatitis, of dextromethorphan along with a second agent that inhibits the enzymatic activity of debrisoquin hydroxylase (also called sparteine monooxygenase, cytochrome P450DB' and cytochrome P450-2D6). Quinidine is an especially potent inhibitor of enzymatic DM oxidation, but it is not well tolerated by everyone. Other antioxidants which are less potent and better tolerated by some patients include quinine, yohimbine, fluoxetine, haloperidol, ajmaline, lobeline, and pipamperone. Since people have major variations in their oxidative enzyme activities, screening tests should be undertaken under the supervision of a physician to select a preferred antioxidant for each particular patient. In tests described herein, patients suffering from intractable coughing or dermatitis which did not respond adequately to any other safe and non-addictive drugs reported excellent results and virtually complete elimination of their coughing or dermatitis. In addition, the treated patients did not report any adverse side effects such as drowsiness, fatigue, or nausea.

Patent CA-2124646-A1 (CA)
Title: Hammers for hammer mills
Inventor: DORSCHT JOHN P
IPC: B02C13/28
Filed: 1994-05-30
Abstract: The hammers provide multiple impact points for debris, by providing impact points via tips at different radii from the axis of rotation of the hammer mill.  The tips preferably are at substantially the same radius from the axis of rotation of the hammer about the hammer support shaft, so that efficiency is maintained even as the hammers lay back.  The multiple impact points produce a more effective result, by partially sizing the debris on initial impact, before more precise final sizing in the grinding chamber.  Angled surfaces on the hammer tips provide more effective shearing and tearing action than with conventional bar hammers.  Wear patterns are such that grinding efficiency as the hammers wear down is maintained throughout the life of the replaceable tips.  Preferably, the hammers weigh substantially more than conventional hammers, to provide a higher energy impact, and to reduce the tendency of the hammers to lay back.

Title: A bottle inspection machine
Inventor: ZODROW RUDOLF
IPC: B07C5/12
Filed: 1993-01-13
Abstract: ABSTRACT            The present invention relates to a bottle inspection machine with a plurality of inspection sections (8-10) that are equipped to perform different inspection tasks and a sorting station (11) which, depending on the results of the inspection, releases the bottles to different conveyor sections (2-5).  In order to provide functional control of the machine, a secondary conveyor section that is formed by a rotating bottle carrier (13) together with the inspection sections (8-10) forms a closed circuit into which test bottles (T) can be introduced from a magazine.  The inspection sections (8-10) that are formed by rotating bottle carriers, like the bottle carriers (13) that form the secondary conveyor section, have receiving points for the bottles on their peripheries and during functional checking form a continuous row with their receiving points.  In this way, a system test of the control systems can be carried out, even with the machine at high operating power, with very few test bottles (T), in particular if the test bottles (T) pass through the machine several times, without manual intervention.            Figure 2 is intended for this abstract.

Abstract: BOW ARM SUPPORT STABILIZER SYSTEM                 ABSTRACT OF THE INVENTION      A bow arm support stabilizer system for supporting the weight of the bow while aiming and shooting is disclosed.  The system has a horizontal connecting shaft with a rear end pinned to the handle section of the bow beneath an intermediate hand grip portion thereof.   A pair  of  closely  vertically  spaced  pins  projecting forwardly from the forward facing edge of the handle section are received in corresponding axial bores formed in  the  shaft  rear  end  to  provide  a  non-rotational connection.  A strap may be used to connect the shaft rear end to the handle section.  A telescopic support rod assembly is pivotally mounted to the front end of the horizontal shaft.   The lower end of the support rod assembly  is  provided with  a  rubber  cap  adapted  to frictionally engage the  top of the archer's shoe to support the bow through the support rod assembly and the horizontal shaft. The non-rotational connection prevents relative twisting movement between the bow and the shaft as a result of high torque at these points of connection generated by the moment arm effect of the support rod assembly relative to the ground.
