Abstract: Abstract of the Disclosure A protective stamp mount has a pair of opposed transparent glass plates which are hinged together by a silicone cement which is received in a recess formed by beveled adjacent edges of the plates.  The other three edges of the plates can also be beveled to provide a recess for permanently sealing the stamp between the plates.  A spacer and border provides clearance between the plates.  In a modified embodiment, a continuous rectangular metal band is sized to receive the plates and provide a metallic periphery for the plates to protect the edges thereof.

Abstract: RAILROAD HAND BRAKE WITH SPRING CLUTCH                 Abstract of the Disclosure A railroad hand brake includes a spring clutch interposed between an operating hand wheel and a gear drive for the chain drum.  The clutch. includes a spring cooperat-ing with a control drum and with an output drum connected to the gear drive.  An input element is rotated by the hand wheel in a forward direction to energize the spring so that the input element, the control drum and the output drum rotate as a unit to take up the brake load.  A ratchet and pawl prevent reverse movement of the control drum in order to maintain the brake load applied when the hand wheel is released.  When the hand wheel is rotated in the reverse direction, the input element tends to deenergize the spring, and the brake load is gradually released with a clutch action characterized by small input force and little wear.  A quick release element operable with a small manual force abruptly uncouples the spring from the load drum in order to free the load quickly while the input element and hand wheel are stationary.

Abstract: SPECTROPHOTOMETER     Abstract The spectrophotometer consists of a plate having a linear photo-diode array and an entrance aperture, a lens 8 and a reflecting dis-persing element preferably designed as an echelon grating.  The en-trance aperture is in the focal plane of the lens.  Since all beams entering through the entrance aperture are directed by the lens in parallel to the optical axis all beams forming any angle of diver-gence, or enclosing any angle within the optical axis, provided these angles are smaller than the aperture angle of the lens, can be measured with the same sensitivity and the same resolution.

Title: Degradation of 1-serine by periodic  acids for reducing scent of mammalian skin
Inventor: JONES DWIGHT G

Abstract: Abstract In sport and commercial fishing much attention is given to techniques and devices for attracting fish, whereas little effort is made to ensure that they are not repelled.  The amino acid l-serine is a strong fish repellent present in the sweat of mammals, and as such contaminates fishing tackle, water, and all surfaces which may come into contact with the human skin. In this invention the amino acid l-serine is degraded through the use of periodic acid or potassium periodate, and the human scent as a repellent is reduced. A dilute solution of periodic acid or potassium periodate as an  active ingredient in a cleaner is applied to the contaminated surface to break down the l-serine. The cleaner may be used when fishing, in aquariums, or in aqua-culture; whenever it is desirable not to alarm fish.

Abstract: RADIO RECEIVER BLANKER INHIBIT CIRCUIT                  Abstract of the Disclosure The noise blanker of a conventional FM radio is inhibited for several seconds upon closing of the receiver's squelch gate.  Following the inhibit period, the blanker is reacti-vated and again inhibited for the full period upon a subsequent squelch gate closing.  Thus, the blanker is inhibited for those signal conditions in which its operation would degrade the overall intelligibility of the processed signal as determined by the squelch control setting.

Abstract: THERMALLY ACTUATED CUT-OFF LINK OR SWITCH       AND METHOD OF MAKING THE SAME                       Abstract of Disclosure An ambient thermally actuated switch comprises a power lead extending longitudinally into and insulated from one end of a metal casing.  The power lead made of a soft low resistance material like copper is bifurcated at its inner end to form outwardly inclining arms which, in a normally closed embodiment of the switch, makes contact with the inner surface of the casing.  The arms are pressed against an insulating backing member so that the arms expand outwardly into a low resistance contact with the casing.  The backing member forms part of a spring-urged, longitudinally extending, sandwich of elements extending between the ends of the casing and preferably comprising a pellet of meltable material, a first partially compressed spring, said backing member, arm-deforming means positioned contiguous to and adapted to collapse said arms when released to do so, and a second fully compressed spring applying a force acting on said deforming means to force it into an arm-collapsing position when the pellet melts.  In assembling the switch, the bifurcated power lead is pushed against the backing member with a force which provides a desired measure low resistance and the power lead is anchored in this adjusted position.

Abstract: ABSTRACT         The invention relates to a method for temporarily alleviat-ing the symptoms of glaucoma. Conventional therapy for glaucoma is with pilocarpine and/or epinephrine administered topically several times daily. One of the problems with many conventional drugs for the treatment of glaucoma is that they decrease the size of the pupil, i.e., they are miotic drugs. This is an undesirable side effect, resulting in temporarily impaired vision. The present in-vention minimizes these difficulties by providing a method of re-ducing IOP and for treating glaucoma in which there is a minimum of miotic side effects. The present invention relates to a thera-peutic composition comprising a topically administrable ophthalmic pharmaceutical carrier and an effective amount of an alkaloid selected from colchicine or vinblastine. The present invention also relates to a method for reducing intraocular pressure and for temporarily alleviating the symptoms of glaucoma in humans comprising topically administering to the eyes of a human, having increased intraocular pressure or having glaucoma an effective amount of the foregoing composition.

Abstract: ABSTRACT OF THE DISCLOSURE       After pulverizing to minus 200 mesh, a mixture of coal and pyrite particles is passed through an A.C. silent corona discharge in the presence of a reactant gas. Simultaneously; the particles are de-agglomerated and an electrical or magnetic difference between them is enhanced. Thereafter, the pyrite is separated from the coal.  The effectiveness of the pulverizing step in separate pyrite particles from the coal matrix, especially small-size particles approximately 50 micrometers and less, is enhanced by pretreating the coal with a chemical comminutant.  One example is a solution of ammonia, used to presoak the coal for a short time, at, for example, atmospheric pressure and ambient temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           An  image  input  terminal  (IIT)  with automatic document handler for feeding documents to be scanned into registered position on the IIT platen. The IIT includes a pair of multi-element scanning arrays with cooperating scan lamp and optics on a movable carriage disposed in scanning relationship with the platen.  Analog image signals gener-ated by the scanning arrays are initially processed in separate channels and then combined into a serial stream. The  stream of  analog  image  signals  may  optionally  be thresholded or  screened  to provide  binary  level  image signals or converted to multi-bit gray scale.     A   control   system   including   microprocessor provides  timing  and  control  signals  for  synchronizing operation of the scanning carriage, document handler, and image signal reading and processing together with elec-tronic crossover between arrays to avoid loss of data, automatic signal gain control, and deletion of bad image signals or pixels.          A  defocused  calibration  strip  is  scanned  to provide  shading  signals  for  calibrating  the  individual scanning elements of the arrays, the shading signals being processed in successive blocks each of which comprises a preset number of shading signals.   Following processing, the shading  signals  are  stored  in memory  and  accessed during normal scanning.  The shading signals are employed in all operational modes to compensate the image signals produced by the IIT for deficiencies in the scanning com-ponents.
