Abstract: TITLE OF INVENTION     Threo-adrenalinecarboxylic acid, and the production and uses thereof.          ABSTRACT OF THE DISCLOSURE      DL- or L-Threo-3-(3,4-dihydroxyphenyl)-N-methyl-serine which may also be termed as DL- or L-threo-adrenalinecarboxylic acid are now provided, which are new compounds useful for therapeutic treatment of Parkinson's disease and mental depression disease.  DL-Adrenalinecarboxylic acid may be produced by a new process comprising reacting glycine with O-protected 3,4-dihydroxybenzaldehyde, hydrolyzing the resultant reaction product under acidic conditions to form O-protected DL-3-(3,4-dihydroxyphenyl)serine, isolating the O-protected DL-3-(3,4-dihydroxyphenyl)serine into the threo isomer and the erythro isomer by recrystallization from a suitable organic solvent, introducing an unsubstituted or substituted benzyl group into the 2-amino group of the resulting O-protected DL-threo-3-(3,4-dihydroxyphenyl)serine, then N-methylating the resulting O-protected DL-threo-3--(3,4-dihydroxyphenyl)-N-benzylserine, and removing the O-protecting groups as well as the unsubstituted or sub-stituted benzyl group at the 2-methylamino group of the N-methylation product.      L-Adrenalinecarboxylic acid may be produced by a new process comprising introducing a p-methoxybenzyloxycarbonyl group into the 2-amino group of the O-protected DL-threo-3-(3,4-dihydroxyphenyl)serine obtained as an intermediate product, optically resolving the resultant O-protected DL-threo-3-(3,4-dihydroxyphenyl)-N-p-methoxybenzyloxycarbonyl--serine by reacting the latter with an optically active amine and recrystallizing the resultant amine salt products from a suitable organic solvent, removing the p-methoxy-benzyloxycarbonyl group from the resultant O-protected L-threo-(3,4-dihydroxyphenyl)-N-p-methoxybenzyloxycarbonyl -serine, reacting the resultant O-protected L-threo-(3,4--dihydroxyphenyl)serine with dimethyl sulfate in dry acetone to form an O-protected L- or D-threo-(3,4-dihydroxyphenyl)--N-methylserine methyl ester, saponifying this methyl ester and then removing the O-protecting groups from the saponifi-cation product.

Abstract: TITLE:  ILLUMINATING TOY UTILIZING CAPTIVE         LIGHT CONDUCTING ELEMENTS                 ABSTRACT      A toy for displaying an illuminated pattern has a first and second panel located in a housing, each panel includng an equal number of a plurality of openings aligned with the openings of the other panel. Located between the panels are light conducting members and an opaque membrane having a plurality of apertures, both the light conducting members and the apertures equal in num-ber to  and aligned with the openings in the panels.  The light conducting members are fixedly retained in the housing and are positionable in a first, or closed, position, and a second, or open, position in association with the panels.  Each light conducting member is capable of being moved from its first to its second posi-tion.  When the light conducting members are in the closed position, the apertures, which are closed,  inhibit trans-mission of light through the light conducting members. When any light conducting member is depressed to the second, or open position, that light conducting member moves into at least partial engagement with the aperture with which it is aligned, thus temporarily completing an optical pathway between the opening in the second panel and the viewing surface of the toy.  A reset means asso-ciated with the housing resets each of the light conduct-ing members to its first, or closed position, allowing the user of the toy to create an unlimited number of new and different patterns at will.

Abstract: Abstract Disclosed is a control unit including a flexible decoder unit providing control patterns  for controlling functional units in data processing equipment.  The control unit  includes  hardwired  decoder logic  which  decodes  a multi-bit key to provide primary decoded outputs as control patterns.   The  decoder  unit  also  decodes  one  or  more alternate decoded outputs  for  future use.   The  decoder includes  a plurality of  flexibility inputs which,  when connected  to  an  alternate  decoded  output,  provide new control  patterns  and  thus  provides  flexibility  to  the hardwired decoder.  Because of the flexibility, the control patterns formed by the hardwired decoder can be readily changed.  The flexible hardwired decoder is of great value, therefore, when design changes are desired in a computer.

Abstract: Abstract A catheter placement device is provided which includes an adapter with an elastomeric grommet having a bore through which a pliable catheter is fed into a blood vessel of a patient.  The grommet has a flange engageable with the catheter and effects a relatively low resistance to distal movement of the catheter and a relatively high resistance to proximal movement of the catheter.  A pair of adapters may be used with one adapter carrying a grommet and the other having a frusto-conical bore receiving an end of the grommet.  The adapters are relatively rotatable to cause the grommet to lock the catheter against axial movement relative to the adapters.  Retention members may be used to prevent inadvertent separation of the adapters during relative rotation.

Abstract: METHOD FOR PRESSING A COMPOSITE ASSEMBLY          ABSTRACT      The present invention relates to a process of forming an extended elongate product from a plurality of strands by subjecting the strands to heat and pressure. The improvement of the present inven-tion comprises a method for compressing the strands in a manner to reduce internal stresses imparted to the product during its subjection to pressure. The method includes the steps of: (a) transporting in a longitudinal direction the strands in a generally parallel and overlapping relationship through a compressing zone of a press assembly;          (b) increasing the pressure on the strands as they pass from an inlet end to an outlet end of the compressing zone by gradually converging facing walls of the press assembly so that: (i) the strands being com-pressed move relative to one another through at least a portion of the compressing zone; and (ii) the strands being compressed lock up so that they no longer move relative to one another but rather only compress relative to one another at a point in the compressing zone where the radius of curvature in the longitudinal direction on either side of a central reference plane of the mat being compressed is at least about 30 feet to provide a low remembered internal stress.

Abstract: ABSTRACT: Method of, and a circuit for, estimating true data from distorted digital data signals.             A method of, and a circuit for, estimating true data from distorted digital data signals in which signals, which may have become degraded due to say noise, are clocked into a shift register (12) at a rate higher than the data rate, for example eight times  the data rate. The n outputs of the shift register (12) stages are coupled to respective inputs of a majority logic circuit (16) which has (n + 1) inputs. A latching circuit (18) clocked in antiphase to the clocking of the shift register (12) is coupled to an output of the majority logic circuit (16). The output of the latching circuit (18) is fed back to the (n + 1)th input of the majority logic circuit.     By having a feedback connection a smaller number of samples can be used to reshape a degrated digital data signal than would be the case without feedback. (Figure 1).
