Title: (b a)-bit-a/d convertor with b-bit auxiliary a/d  convertor
Inventor: PEEK JOHANNES B H

Abstract: ABSTRACT:          An analog-to-digital converter is described for converting an analog-signal into a sequence of (b+a)-bit code words by means of a b-bit auxiliary analog-to-digital converter.  To reduce the quantizing noise result-ing from the requisite quantizing of the analog signal samples this analog signal is applied to an integrating network whose output is connected to an amplitude-limit-ing device which brings the integrated signal within the signal range of the auxiliary analog-to-digital converter, which in its turn produces a sequence of b-bit code words which are applied to a digital output filter via a cascade arrangement of an amplitude-restoration device and a difference network.         Sampling pulses which occur at a frequency exceeding the Nyquist sampling frequency associated with the analog signal are applied to the auxiliary analog-to-digital converter.

These polypeptides have the capability of in-ducing the differentiation of T-lymphocytes as measured by the acquisition of the thymic differentiation antigen Th-l, as well as B-lymphocytes as measured by the acquisi-tion of the differentiation antigen Bu-l.  The polypeptides are thus useful in thymic function and immunity areas such as in treatment for congenital absence of thymus.  Also provided are therapeutic compositions and methods for use of the polypeptides.

Abstract: ABSTRACT OF THE DISCLOSURE A container and method of adhesive bonding of two tele-scopic container halves wherein each container half has a cylindrical body, the inner container portion being circum-ferentially loaded to temporarily reduce its diameter and being forced in centered relation to the outer portion into a bead of adhesive laid in the interior of the outer portion to coat the raw edge on the inner portion, the inner portion shearing through the adhesive without wiping it off from the interior of the inner portion and thereafter the hoop stress on the inner portion being relieved so it springs out and squeezes excess bonding material from between the inner and outer portion and thus obtains a thin film adhesive bond with good stress shear characteristics while holding the film in compression therebetween during curing or setting of the adhesive.

Abstract: Abstract A time interval meter for measuring extreme-ly  short  time  intervals  includes  a  timing  circuit operable at  a  fast  predetermined  rate over  the time interval between first and second events, and operable at a slow predetermined rate which is precisely scaled to  the  first  rate over a  time  interval between  the occurence of the second event and the upper limit of a predetermined  timing  window.  During  the  slow  ramp period,  clock pulses are  counted to provide a  count which is proportional to that portion of the predeter-mined  timing window occupied by the slow ramp inter-val. The fast  ramp time interval may then be readily attained by  subtracting  the  slow ramp interval  from the  total  time  of  the  timing  window.  The  circuit includes a control circuit, a timing circuit including a capacitor and a pair of selectable constant current sources, and a counter.

Abstract: Transmission Filler Assembly Abstract Service personnel may confuse one dip stick for another in vehicles having a number of fluid reservoirs.  When the reservoirs have air entrapped within them during filling, hydraulic lock can occur. Herein, a filler tube structure and a dip stick tube structure have their top ends held within a tubular fitting which is covered by a single cap.  This eliminates any possible confusion as to the dip stick tube structure which corresponds to a particular reservoir or chamber.  In the preferred embodiment venting of the chamber to which the fluid is being added is provided via an interior passage of the dip stick tube structure, thus preventing hydraulic lock.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a medical device, namely a novel clip to be used in conjunction with a Harrington rod for the treatment of spinal disorders.  The hook has a body portion with a housing at one end thereof, with a hooked portion at the opposite end. A sleeve is inserted through and is retained in a channel which extends through the housing by a retaining means.          Using this clip, it is possible to spread the load over more than one lamina as more than one hook may be used in the proce-dure.  This thus allows a patient to be mobile without external support immediately following surgery which has been impossible with the prior art devices.

Abstract: ABSTRACT   A description is given of a method for non-contact measurement of direct and alternating currents, more particularly instantaneous current-values, using an iron-circuit having an air-gap, a magnetic-field-dependent resistor through which a control-current flows, and at least one winding through which a measuring current flows.  In order to obtain the highest possible measuring speed which will detect a rapid instaneous value, e.g. any high peak-currents arising, at an equivalent current winding is arranged in the iron circuit.  The voltage-drops at the magnetic-field-dependent resistor, in the event of peak-values or other typical values of the current to be measured, are detected and stored, while no current flows in the equivalent-current winding,  thereafter, the current to be measured is stopped and current is caused to rise on the equivalent current winding.  The stored voltages are compared, consecutively with the voltage-drop at the magnetic-field-dependent resistor, with the rising current in the equivalent-current winding are indicative of the typical values being measured.  To obtain the exact typical values of the measuring current the equivalent current values are multiplied according to the number of turns of the equivalent winding.
