Patent CA-1110819-A (CA)
Inventor: VANDENHOEK HAROLD L
IPC: E05D5/02
Filed: 1979-02-23
Granted: 1981-10-20
Abstract: ABSTRACT OF THE DISCLOSURE                  The specification discloses a panel system in which panels are joined by one (at an angle) or two (in a straight line) elongated, flexible hinge(s) which is secured to each of the panels to be joined by being clamped between the end of the panel and an end cover which is readily removable from the panel.  The end cover and the end of the panel both include flanges which interengage.  The flanges on the end of the panel are relatively short so that by sliding the end cover only a short distance verti-cally, one can either secure it in position or remove it.      The end cover includes a top shoulder and the end of the panel includes a bottom shoulder between which the elongated flexible hinge member extends with its top edge generally adjacent or abutting the top shoulder and its bottom edge generally adjacent or abutting the bottom shoulder, such that two adjacent panels joined by the hinge are automatically properly aligned.

Abstract: ABSTRACT OF THE DISCLOSURE A process and a device for gutting fish with voluminous belly contents such as fish before spawning or tunny-species, is described. Non-decapitated fish lying on their backs and with their tail ends leading, are conveyed successively along a trough-shaped path in the direction of their longitudinal axes. While the fish are advancing, their belly cavities are cut open by a slitting knife. Thereafter, the intestines are loosened and removed upon fluid-floating by suction pumping after comminution and severing of parts of the intestines. To this end there is provided a water supply and cleaning tool in the form of a suction pump including a star-shaped rotating ejector.

Abstract: ABSTRACT OF THE DISCLOSURE           A practice projectile is described which comprises a tubular body having a closed downstream end and an open upstream end.  A nose cap closes the open upstream end and is secured to the tubular body.  Driving means are provided on the exterior of the projectile to impart spin to the same upon launching.  According to a particular feature of this invention, stress raising means are provided in the tubular body.  These stress raising means operate to increase tensile stresses in the tubular body to a predetermined value which, upon impact of the projectile with a target or the ground, causes total stresses in said body to exceed a designed maximum value.  Those excess stresses cause break-up or frag-mentation of the projectile.  The stress raising means in some instances are tubular boreholes extending axially in the tubular body, and spaced symmetrically to maintain mass symmetry, thus resulting in stability in free flight.  In more preferred forms the stress raising means are axial grooves in at least one of the inner and outer surfaces of the tubular body.     MR/

Abstract: Abstract of the Disclosure A drop-on-demand ink jet printer in which the print head includes a cavity having a nozzle portion at one end and a transducer mounted to contract a wall portion of the cavity when energized by a suitable voltage drive pulse.  The drive pulses are produced at a pre-determined rate but at a selectively controlled ampli-tude in response to the print data.  In cases where no drop is required to print the data, the drive pulse is at a lower amplitude than the threshold voltage level, and for the first drop to be formed following a time at which no drop was formed, the amplitude of the drive pulse is greater than the threshold voltage level,  At steady state operation of producing drops in sequence, the amplitude of the drive pulses equals the threshold voltage level.

Abstract: ABSTRACT OF THE DISCLOSURE A water slag granulator adopts a slurry tank and a sedimentation tank each provided with a screw conveyor or dewatering a slag slurry as it is transferred from the bottom of each associated tank where it is precipitated towards the outside of the tank.  Thus, dewatering tanks as used in the prior art equipment can be dispensed with.  Also, the dewatering operation can be peformed continuously and efficiently in the apparatus using the screw conveyor for the dewatering purpose, instead of a batch type dewatering system of the prior art.  Further, the blowing jet water can be controlled responsively to the molten slag feed and, thus, a relatively small water reservoir is sufficient for accomodating the molten slag feed variation, contributing to a reduction in the equipment cost.

Abstract: PROCESS FOR PREPARING CARBAMYL DERIVATIVES OF  .alpha.-HYDROXY ACIDS AND THE CORRESPONDING d-HYDROXY ACIDS.                        ABSTRACT This invention relates to a process for preparing carbamyl derivatives of .alpha.-hydroxy acids by the hydrolysis of 5-substi-tuted 2,4-oxazolidinediones.      The carbamyl derivatives can be further hydrolysed to .alpha.-hydroxy acids.          The invention also relates to a process for the enzymatic hydrolysis of raceme 5-substituted 2,4-oxazolidinediones to give only one of the two possible optical isomers, i.e. the D-carbamyl-.alpha.-hydroxy acid.   The free D-.alpha.-hydroxy acid can be obtained from the optically active carbamyl derivative by simple hydrolysis.   Of particular interest is the case in which the D-.alpha.-hydroxy acid is D(-)mandelic acid.   The enzymatic activity required for preparing the carbamyl derivative of D(-)mandelic acid has been found both in homogen-ised veal liver and in a series of microorganisms, including Agrobacterium radiobacter, Bacillus brevis, Bacillus stearo-thermophilus, Pseudomonas sp., Pseudomonas desmolytica, Pseudomonas fluorescens, Pseudomonas putida.
