Abstract: IMPROVEMENTS IN SENSITIVE DOOR EDGES              Abstract of the Disclosure A sensitive edge 10 for door systems, lifts, doors, or other moving portions of transit vehicles that come into contact with articles or passengers includes a body defining a resilient deformable leading edge portion 30 and a base portion 32 within which is defined an internal chamber.  A coupling portion is defined on and extending from the base for coupling the sensitive edge to the door or similar device 36.  The chamber 34 is hollow and at atmospheric pressure and in the preferred embodiment, is filled with air.  Within the chamber is mounted a Wiegand wire and pick-up coil 38 that is electrically coupled to a switch for recycling the door or similar device upon engagement of the sensitive edge with an object such as a passenger.  Also mounted within the chamber and spaced from the Wiegand wire or pick-up coil and wire is a magnet or similar magnetic field creating device 40 such that upon defor-mation of the sensitive edge, the magnet and Wiegand wire are brought sufficiently close together to cause a switching function to open the door or similar device.

Abstract: ABSTRACT    A process for preparing whole blood reference controls having long term stability up to six months for devices using electronic means for whole blood determinations including platelet count and mean cell volume and red blood distribution width.  The preconditioning diluent for the red blood cells consists essentially of an aqueous solution of lactose, sodium azide, and a non-ionic surfactant and is pH buffered and osmolality adjusted.  The media of the whole blood control includes lactose, fungicides and antibiotics, and supplementary agents including purine nucleosides.  It also includes additional components which alter red blood cell membranes including bile salts and cholic acid derivatives, phenothiazine compounds and the salts thereof having antihistamine properties, and 4-aminobenzoic acid ester derivatives and their salts having local anesthetic properties.  In the process, the red blood cells are separated from the whole blood and preconditioned by the diluent to attain desired size distribution width and volume.  The preconditioned red blood cells then are mixed in the media in suitable number for yielding the desired cell count for the whole blood reference control.

Abstract: ABSTRACT OF THE DISCLOSURE           A compressor start fault detection and control sys-tem for a reverse cycle refrigeration system for detecting faulty compressor startup operation and for controlling the system in response to the detection of a fault by inhibiting the compressor and for providing a fault indication.  The con-trol system comprises a controller receiving an input indica-tive of the temperature of the compressor discharge refrigerant and an output indicative of a demand from a building tempera-ture sensor for heating or cooling of the building.  The con-troller also includes (i) a timer, (ii) a comparator for com-paring the value of the compressor discharge temperature at the time of compressor start up and the value of the com-pressor discharge temperature after the compressor has been operating for a preselected time interval and (iii) circuitry to inhibit any further operation of the compressor unless the value of the later compressor discharge temperature is greater than the value of the initial or start up compressor disclos-ing temperature plus a preselected constant.

Abstract: INERTIAL DEFLECTION FIELD TILTING FOR      BI-DIRECTIONAL PRINTING IN INK JET PRINTERS               Abstract of the Disclosure In a continuous type ink jet printer having a conventional charging electrode for charging ink drops in accordance with a signal to be recorded on a record receiving media, a pair of deflection electrodes is mounted in a rocker which pivots on a holder mounted on the carrier.  As the carrier is accelerated from the stop condition to print speed, the acceleration of the carrier effects rotation of the rocker about the pivot and thus automatic tilt of the deflection electrodes backward from the direction of carrier movement thereby tilting or inclining the electric field formed between the electrodes to compensate for carrier movement.  In the preferred form, a simple magnetic type latch is applied to retain the rocker in one position for printing in a first direction, and to enable quick release and reversal, under inertial control, when the carrier moves in the opposite direction.

Abstract: A B S T R A C T            F12312/A3405      IMPROVED FRAME ALIGNER FOR        G. Chopping DIGITAL TELECOMMUNICATIONS    EXCHANGE SYSTEM            An aligner is used in a digital telecommunications switching system for correcting the drift between the exchange clocking system and the incoming digital line terminated on the digital line termination units DLT.  Typically aligners consists of so-called "elastic-lengthed" buffers having two frames worth of storage arranged such that the line information is written into one "frame area" while the time switch is fed from the other "frame area" and vice versa for each successive frame. Such an arrangement has severe limitations from a fault finding point of view.  The aligner of the invention consists of a "single chip" containing a set of five half frame serial shift registers together with read and write address counters and associated logic to ensure that separate "read" and "write" shift registers are maintained.  The use of five half frame shift registers through which the serially received data is passed allows the sync channel (time slot zero) to be monitored which ensures that the aligner is functioning correctly because the sync channel is fed through all the locations of the aligner.  The sub-division of the total store into odd numbers allows each register selection to be checked periodically for the appearance and non-appearance of the synchronisation pattern.  In addition the checkable channel pattern is arranged to be the last entry written to each register before the counter moves to a new register, hence, the counter itself is checked across its full range.

The mixture of the diastereoisomer amides thus obtained is resolved by fractional crystallization from organic solvents into the respective separated diastereoisomers.      These optically active amides are useful therapeutic agents for treating cardiac disorders, hyperlipidaemias and hyperlipoproteinaemias and, furthermore, can be hydrolyzed with procedures known per se into L-carnitine and D-carnitine, respectively.

Abstract: ABSTRACT OF THE DISCLOSURE Three or more work rolls are arranged substantially in line with each other so that the adjoining work rolls each form a roll pass between them.  The work rolls are driven in such a way that the rolls closer to the exit end of the rolling mill stand rotate with increasingly greater peripheral speeds.  Metal strip is continuously passed through each roll pass and is wound around part of the periphery of the work rolls disposed between the work rolls at both ends of the stand.  Thus, the strip is rolled between each pair of the adjoining work rolls.  The work rolls are also driven in such a way that at least in one of the pairs of the work rolls, the peripheral speed of the higher-speed work roll is greater than the speed with which the strip leaves, the roll pass formed by said pair of work rolls.

Abstract: Abstract of the Disclosure An image data conversion technique is disclosed in which the picture image data is converted into a runlength code in order to compress the bit information to be transmitted.  The invention achieves a shorter conversion time than prior systems while at the same time ensuring that a smaller conver-sion table than required by other prior systems can be used.  Particular use is made of a character code/character pattern converter.  This latter circuit includes a character pattern generator which generates a character pattern signal corresponding to the character code.  A converter converts the character pattern signal to a runlength code and this is then multiplied by a character enlargement coefficient.  A character interval is then added to the enlarged runlength code and an output signal obtained.
