Abstract: ABSTRACT          A racket frame is made by molding a thermosetting resin composition together with reinforcing fibers.  Molds are made of flexible strip members, such as plastics, wood pulp, paper pulp, wood, bamboo, etc., which are bent to form a racket frame in a fitting, thereby reducing the production cost incurred in fabrication of expensive molds.  The formed racket frame has no shell and core structure.

Abstract: ABSTRACT OF THE DISCLOSURE        A tamping machine is disclosed which has two tamping units which are inclinable transversely to the track in order to tamp the track switches.  Each of these tamping units is articulated at its upper part on a slide which is displaced by a cylinder-piston unit on a transverse slideway fastened on a rigid frame.  This frame is mounted for pivoting around a vertical axis on two brackets fastened to the frame of the tamping machine.  The inclination of each tamping unit is coordinated with its translation on the slideway by a rod which connects an element of the tamping unit to the chassis so as to reduce the differences in tamping depth caused by the transverse displacement of the tools.  The lower portion of the tamping units comprises an arm engaged in a curved slideway fastened to the frame in order to transmit the longitudinal tamping forces to the latter.  The tamping units of the present invention avoid problems involved with known tamping units, including substantial bending stresses in the units, unsatisfactory displacement problems, difficult align-ment problems and mobility problems.

Abstract: ABSTRACT OF THE DISCLOSURE     A semiconductor optical switch having a P-N junction with an active layer coupled with an input and output wave-guides has been found.  An input optical  signal with the wavelength close to the center Or the gain spectrum defined by said P-N junction is applied to said active layer, and said input optical signal is switched ON and OFF according to the injection current applied in said P-N junction. Said injection current for turning ON the optical switch is in the range between 80% and 90% of the threshold current which initiates oscillation operation of said P_N junction. When injection current is zero, an input optical signal does not appear at an output, and with the above injection current Or 80-90% of the threshold current, an input optical signal appears at an output terminal.  When a switch is in ON state, an input optical signal is amplified with some gain.

Abstract: ABSTRACT OF THE DISCLOSURE           Proteins are radiolabeld with technetium-99m in a reducing environment comprising buffered stannous chloride where-in the tin utilized to form the stannous chloride is non-oxidized, the buffered stannous chloride is purged of oxygen and the buffer comprises an alkali metal biphthalate and an alkali metal tartrate.         Proteins which have been preincubated with tin are radiolabeled with technetium-99m to form a strongly bonded, non-exchangeable radiolabeled tracer substance.  The radiolabeling can be accomplished immediately after pretinning, or the pretinned proteins can be freeze-dried and the radiolabeling accomplished at some time in the future when the pretinned proteins are re-solubilized in a saline solution of sodium pertechnetate - Tc-99m.          Pretinning can be accomplished in a reducing environment comprising stannous chloride buffered with an alkali metal biphthalate and an alkali metal tartrate, this solution having been purged of oxygen to assure that the stannous chloride is non-oxided.  When the pretinning proteins are freeze-dried, they can be utilized to prepare instant Tc-99m labeling kits for use as radio-pharmaceuticals.

Abstract: ABSTRACT OF THE DISCLOSURE         A  unique  design  and  method  of  construction  is presented for a tank-like structure which houses an electrical component immersed within a dielectric fluid.   The tank is formed by a generally cup-shaped enclosure and a cover.   In one  embodiment  the cover  carries a means  for  electrically connecting the interior of the tank with its exterior.   The cover  and  the  enclosure are joined by an overlapping edge means.  By overlapping the marginal portions of the cover and the enclosure, such that the leading edges are disposed in the opposite direction, a joint is formed which is less likely to rupture than one formed by overlapping the marginal portions with the leading edges disposed in the same direction.   The overlapping edge means, allows the designer to pre-select that portion of the interface between the cover and the enclosure where, in the event of an overpressure condition within the tank, a rupture should preferably occur, thereby minimizing the damage  which  could  result  from  the  discharge  of pressurized gas and liquid.   The tank design also includes provision for a retention means to hold the solid portions of the electrical apparatus housed by the tank within the tank in the event that the tank ruptures and fluid is lost.  Several specific embodiments are illustrated and described in detail, with specific reference to a tank which houses a plurality of capacitor packs.

Abstract: ABSTRACT        The operation of a coin testing apparatus is checked by switching the apparatus to a test mode.  In the test mode, the properties of items inserted into the apparatus are compared with stored "test" ranges, instead of "acceptability" ranges which are normally used to determine whether the item is a genuine coin.          A specially designed non-genuine coin is then inserted into the apparatus.  If the measured properties of the non-genuine coin fall within the "test" ranges, a signal is produced to indicate that the apparatus is operating correctly.  If any of the properties falls outside a "test" range, but within a further, contiguous range, a signal indicates that the apparatus is working adequately, but not optimally.

Abstract: ABSTRACT OF THE DISCLOSURE          OPTICAL MEMORY SYSTEM HAVING AN IMPROVED LONG SEEK CAPABILITY         A high density optical storage system employing a laser beam for reading data in a track on a rotating optical disk containing a large number of closely spaced concentric tracks.  When a long seek operation is to be provided, track following is suspended and a linear motor drives a galvanometer-controlled mirror to a new position corresponding to a new track called for by the long seek operation.  Arrival at the new position is determined by detecting when both the velocity of the linear motor and the difference between current and desired positions are below predetermined maximum values indicating that a stable condition has been reached, after which track following operation is resumed.  The linear motor also operates during track following in response to the detected angular position of the mirror so as to cause movement of the mirror in a direction which reduces the mirror deflection required to maintain the beam accurately following the track.

Abstract: ABSTRACT               PREPARATION OF 4-(.alpha.-ALKYL-.alpha.-CYANO-METHYL)-2,6-DI-SUBSTITUTED PHENOLS     4-(.alpha.-alkyl-.alpha.-cyano-methyl)2,6-di-substituted phenols having the formula   wherein R is hydrogen, methyl, ethyl, n-propyl or isopropyl and R1 and R2 are the same or different monovalent substituent selected from the group consisting of alkyl, aralkyl and cyclic alkyl radicals and are prepared by reacting a di-substituted phenol having the formula   wherein R1 and R2 are as defined above with an aliphatic aldehyde having a single aldehyde radical selected from formaldehyde, acetaldehyde, propion-aldehyde or butryaldehyde and an alkali metal cyanide or an alkaline earth metal cyanide in a suitable solvent.  The 4-(.alpha.-alkyl-.alpha.-cyano-methyl)2,6-di-substituted phenol thus formed can readily be converted to the corresponding 4-(.alpha.-alkyl-.alpha.-cyano-methyl)phenol by dealkylating the substituent groups ortho to the hydroxyl group from the 4-(.alpha.-alkyl-a-cyano-methyl)-2,6-di-substituted phenol which then can be converted on hydrolysis to the corresponding .alpha.-alkyl-4-hydroxyphenylacetic acid.  These acids are well-known insecticidal and acaricidal intermediates.
