Abstract: ABSTRACT OF THE DISCLOSURE    A guide clamp is disclosed which includes a clamping jaw at one end of a guide bar.  An opposing shifting jaw is slidably carried on the guide bar to permit a workpiece to be embraced by the jaws.  A pull rod associated with and parallel to the guide bar is connected to a lever on the clamp jaw.  The shifting jaw locks onto this pull rod when the jaws embrace a workpiece and actuation of the lever then pulls the jaws together to clamp onto the workpiece and hold the guide clamp thereon.  The shifting jaw will lock onto the pull rod by engaging a smooth-surfaced pull rod with a frictional grip or by engaging threads or notches on the pull rod with a locking grip.  Guideways to guide and hold tools, jigs and the like are provided on the guide bar.

Abstract: Abrégé Procédé de salage des grains de caillé de fromage permettant la maîtrise de l'évolution fermentaire du caillé en cours de travail technologique, et la machine pour la mise en oeuvre du procédé. La maîtrise du développement de fermentation dans la fabrication du fromage, à chacune des étapes est très difficile. L'innovation technologique du procédé selon l'invention permet à un moment critique de la fabrication (au cours duquel antérieurement on n'avait aucun moyen d'intervenir), de ralentir ou d'accélérer l'activité des fermentations et donc de maîtriser la modification du substrat, sans avoir à subir les conséquences de la poursuite de cette activité liée à la température au cours de la phase d'égouttage. Selon le procédé à la fin du travail mécanique et de l'égouttage, on immerge les grains de caillé dans un bain de saumure sans modification de leur aspect à une température contrôlée du bain indépendante de la température au cours de la phase d'égouttage, et en salant les grains de caillé dans ce bain de saumure salé à un taux déterminé, constant et contrôlé, lesdits grains étant évacués vers une zône d'égouttage, en vue des phases ultérieures de fabrication du fromage.

Abstract: ABSTRACT     A multistate organic optical storage medium is disclosed, wherein an optical beam can switch any "data storage spot" on said optical storage medium into three or more memory states.          The optical storage medium may consist of a mixture of bistate switching modules, or it may consist of large delocalized amphoteric molecules.  The illuminated area of said optical storage medium will undergo an electrochemical topactic redox reaction which will cause certain moieties in the illuminated area to change oxidation state.  By changing the intensity of the optical "write" beam the illuminated area can be switched to a plurality of specific states each state having a unique set of oxidation species.  An optical/spectroscopic means is used to identify the presence of oxidation species and to "read" the data stored.

Abstract: ABSTRACT OF THE DISCLOSURE:           An air scrubber apparatus which purifies foul air produced during an embalming, an autopsy or the like carried out on a work table disposed in a room. This scrubber appa-ratus comprises a housing positioned above the work table and defining a central compartment provided with a bottom opening, and first and second longitudinal, side compartments adjacent  the central compartment and provided with end outlets to the room.  An air filter is positioned over the bottom opening of the central compartment and comprises a filtering material including aluminium oxide and potassium permanganate.  First and second fans move the foul air towards the interior of the central compartment through the air filter for the purpose of purifying this foul air.  The first fan also transfers the purified air from the central compartment to the first outer compartment while the second fan transfers it from the central compartment to the second outer compartment, to thereby disperse the purified air in the room through the end outlets of the outer compartments.  At least one ultraviolet ray tube or an additional filter may also be provided to kill germs, bacteria and the like present in the moved foul air. In order to increase the efficiency of the scrubber apparatus, a wall structure may define a substantially closed volume between the housing and the work table.

Abstract: HIGHLY INSULATING BRICK FOR MASONRY            Abstract of the disclosure The brick consists of one or more sub-blocks. Each sub-block is divided into air chambers of contained width but extensive in length. The walls which divide each sub-block into chambers are shaped as alternatively concave and convex arcs of a circle. The chambers are connected by first septa of minimum length. The sub-blocks are connected by second septa also of minimum length and never coincident with the periphery of the brick nor placed in correspondence with the inner cores of the successive sub-block, on a line with them.     Thermal bridges between the inside and outside of a wall are thus almost completely eliminated, with a brick light in weight, very strong and low in cost.

Abstract: RADAR WARNING RECEIVER                Abstract of the Disclosure A radar warning receiver includes means for distinguishing pulsed or  continuous fixed frequency radar signals emanating from a radar transmitter from variable  frequency  signals  such  as  those  radiated from a nearly superhomodyne receiver.  This invention includes  a  superheterodyne  receiver  having  a  local oscillator  that  is  repeatedly  varied  in  frequency over a range of frequencies sufficiently large and at a rate fast enough to cause any signals within an input range of frequencies to be detected by a sensi-tive, limited bandwidth detector.  If an input signal is fixed in frequency, that signal will be detected at  the  same  time during  successive sweeps  of  the local  oscillator,  and  a  correlated output will be generated; otherwise, an uncorrelated output will be generated.  If the number of correlated outputs equal or exceed the uncorrelated outputs detected, then an alarm is provided.   Even when the  receiver of this invention is receiving signals from a superhomodyne receiver, if a fixed frequency signal is detected for a predetermined number of consecutive sweeps of the local  oscillator,  then  an  alarm,  indicating  the presence  of  that  fixed  frequency  signal,  is  again provided.

Abstract: ABSTRACT OF THE INVENTION   The present invention provides a quick hitch for connecting a prime mover to an implement to be used with the prime mover.  The prime mover has a male assembly which can be quickly and easily hitched and unhitched to the female assembly of the implement.  The male and female assemblies matingly receive one another and a locking mechanism on the female assembly maintains the two assemblies in a locked relationship.  The prime mover is driven towards said implement until said male and female assemblies matingly engage one another, thereby engaging the locking mechanism and hitching the implement to the prime mover.  To unhitch the male an female assemblies, the locking mechanism is moved to the unlocked position and the prime mover is driven away from the implement.

One of the jaws includes an assembly of probes mounted for longitudinal displacement in a direction normal to the  longitudinal  axis  of  the  pipe  or  coupling,  the probes  also  being  slideably  supported  within  the assembly  for  transverse  displacement  in  a  direction parallel  to  the  longitudinal  axis  of  the  pipe.          Transducers are provided for measurement of the motion of the probe.  The second jaw coacts with the first jaw for clamping the assembly to the pipe thread.  During the   clamping   action,   the   probes   are   displaced transversely so as to set into troughs of the threads whereby  the  probes  are  aligned  for  measurement  of thread length.   The taper is measured by means of an inclinometer disposed at the end of the assembly away from the probes.   Normal displacement measures thread height  as  well  as  deviation  in pitch  line,  the  latter providing  a measure  of  the  non-linearity  of  the  thread pitch line.
