Title: Clinical analysis methods and systems
Inventor: MAZZA JOHN C
IPC: B01F33/40
Filed: 1987-04-29
Granted: 1991-07-09
Abstract: ABSTRACT          An improved and unique mixing technique particularly useful as part of the process for the clinical analysis or liquid biological samples is described.  The sample is placed in a cuvette along with a reagent and a diluent.  The top (opening) of the cuvette is squeezed (reduced in size) and an air jet is directed against the liquid surface formed in the cuvette adjacent the junction of the liquid surface with the wall of the cuvette to create a vortex to produce thorough mixing of the contents of the cuvette and substantially prevent any splashing of the liquid contents.

Abstract: Data Transmission System Abstract of the Disclosure Data is  transmitted from  a mobile  or a  base station to a booster or repeater station which,  if  it  identifies,  that the same message  has been  retransmitted a preset number of times by the mobile  or base  station it automatically  retransmits the data. The number of times a message has been retransmitted may be coded on each message  or  determined  by  comparing  the retransmitted messages with a peviously sent message that will have been stored in memory by the repeater and  when  the  message  in  memory and retransmitted   message   are the   same,  registering  another transmission of the message until the preset number is registered and then retransmitting the message preferrably from memory.   In another arrangement the  relay  station  receives  and  stores or otherwise identifies data from the mobile or base and listens for an   acknowledgement  from   the   receiving   station,   if  no acknowledgement is  received within  a preset  period of time the message is automatically retransmitted by the relay station.   In either  case  the  first  time  a message is received it will not except in certain circumstances be retransmitted by the repeater.

Abstract: ABSTRACT OF THE DISCLOSURE         A  plastic  encapsulated  integrated  circuit package in which a chip is secured to the upper surface of a base and is connected to leads which have their lower surfaces in a plane above that of the bottom of the base. An electrostatic shield is electrically connected to the bottom of the base and underlies the leads without touching them, to reduce crosstalk. The support for the base is integrally connected by a conductive strip to the lead  for  the  ground pin  of  the  chip,  to  ground  the shield.  The whole  is plastic  encapsulated.  To  permit encapsulation, the shield extends towards but stops short of the dam bars for the leads.

Title: Synchronous demodulator with digital signal output
Inventor: SCHROEDER WERNER
IPC: G06F3/05
Filed: 1987-11-03
Granted: 1991-09-17
Abstract: Abstract:    A synchronous demodulation system with digital signal output contains a summation circuit receiving an input signal to be demodulated and a control signal.  The output of the summation circuit is applied to a synchronous demodulator which feeds into a controller.  The controller comprises an integrator, which precedes an A/D converter and a processor that acquires the output pulses of the A/D converter.  The processor drives a D/A converter supplying the control signal to the summation circuit so that the summation of the input signal and the output of the D/A converter, averaged over time, leads to an (approximately) zero signal in the synchronous demodulator.  Due to digital control the circuit is distinguished by a large dynamic range and high accuracy with simultaneous insensitivity.

Abstract: TIE-DOWN SECURITY SYSTEM AND SECURITY PLATE               ABSTRACT OF THE DISCLOSURE           An improved security system for preventing the theft of items, such as typewriters and personal computers.  The system has a security plate which is fixed to the item that is to be secured.  A bendable member is permanently attached to a center area of a plate base, and has a free end spaced from the center area of the base.  A loop is advantageously formed on the free end for attaching the bendable member to a cable, chain or the like used to attach the plate to the anchor.  When an attempt is made to forcibly remove the item, the bendable member bends to direct the removal force to the center of the plate where it can be distributed over the entire base and thereby more effectively resisted.

Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed in an optical information recording and reproducing apparatus in which parts including a one-chip microcontroller, an error flag counter and an error comparison circuit are provided to detect whether or not an optical disk or an internal optical head of the apparatus is fouled.  When the optical disk or the internal optical head is fouled due to attraction of dust floating in air, a recording laser beam is scattered by the dust resulting in reduced recording power, and a reproducing laser beam is also scattered by the dust, with the result that signal recording and reproduction cannot be satisfactorily carried out.  In the optical information recording and reproducing apparatus, test data is recorded on a self-diagnostic area of the optical disk when the optical disk loaded in the apparatus is new and has not been used yet, and initial error information detected in the test data reproduced from the self-diagnostic area is registered on an error managing area of the optical disk.  On the other hand, when the optical disk which has been used already is loaded, error informa-tion detected in the test data recorded on and reproduced from the self-diagnostic area of the optical disk is compared with the initial error information registered in the error managing area of the optical disk.  When the result of comparison proves that the number of data errors increases over a predetermined reference value, the optical disk or the internal optical head is fouled with dust to such an extent that the recording and reproducing function cannot be satisfactorily performed.

Abstract: ABSTRACT          COMBINATION OF AN INJECTING UNIT AND PLASTICIZING UNIT FOR          AN INJECTION MOLDING MACHINE         The means for locking a horizontal plasticizing cylinder to the carrying block of the injecting unit of an injection molding machine comprises two cylinder-locking sliders, which are disposed on opposite sides of the axis of said cylinder and are radially movable by means of hydraulic cylinders. In a locking position, said sliders extend in diametrically opposite recesses of the plasti-cizing cylinder. A shaft for driving the feed screw of the plasticizing unit comprises a coupling section, which is formed with a radial guide groove, in which a screw-locking slider is radially displaceably mounted. That screw-locking slider is non-rotatably connected to said shaft. A coupling bridge is secured to the upper one of the cylinder-locking sliders. When the feed screw is in a desired angular position said coupling bridge is coupled to the screw-locking slider so that said one cylinder-locking slider and said screw-locking slider are simul-taneously moved to their locking position. Such an ar-rangement will facilitate an automatic change of the plasticizing unit and will also facilitate the manufacture in series and the assembling because an unlocking movement of the screw-locking slider can directly be derived from an unlocking movement of the cylinder-locking slider.

Granted: 1992-03-17
Abstract: ABSTRACT         Ultrasonic  vibrations  indicating  trouble  at  remote locations are detected by sensors spaced in the vicinity of expected  trouble.    These  sensors  have  weather  resistant transducers that convert ultrasonic vibrations from a leak in a conduit, electrical arc, bearing vibration or like, into an electrical  signal.   In the  sensor there  are circuits that amplify the electrical signal and transmit it with a current loop transmission system over a twisted pair of wires to a central control and analysis computer.   The amplification of the signal at the sensor is controlled by a signal from the central computer which changes the gain increments until the sensor circuits are not saturated by the ultrasonic signal. This gain control signal is also delivered to the sensors over a twisted pair of wires by current loop transmission system.            (19)
