Abstract: ABSTRACT OF THE DISCLOSURE           In an analog-to-digital converter for amplitude modulated pulses, two converters are used, each responsive to signals of one sign, and the sign of the signal is determined after conversion by determining which converter has produced an output, so as to avoid errors in sign identification due to sampling tansients.          Bits representing the sign and the encoding of the pulses are organised into a desired order using a parallel-in, serial-out register.

Abstract: INTRAVENOUS CATHETER ASSEMBLY WITH  FLUID FLOW RESTRICTION CAPABILITY                ABSTRACT OF THE DISCLOSURE    An intravenous catheter assembly for use in the administration of fluids to a patient includes a compressible, flexible hub having a bore therethrough. One end of the bore is adapted to receive a hollow tube such as an intravenous catheter so that fluid is flowable through the bore and the tube.  A pair of generally oppositely extending wing sections is connected to the hub, at least one of the wings being hingedly connected to the  hub to allow that wing to fold over the hub.  On the hingedly connected wing is a pinching protuberance for contact with the hub when the wing is folded thereover whereby, in use, the folded wing urges the protuberance against the flexible hub causing it to collapse and occlude the bore and thereby restrict fluid from passing therethrough.

Abstract: Abstract of the Disclosure A temperature compensated current source includes three successive source current paths to produce a controlled output current.  Each current path has a different value of current flowing therein so that current fluctua-tions in one current path will tend to be isolated from the other current paths because of the difference in current flow.  In the embodiment of the invention shown, a reference zener diode provides a reference voltage at the base of a first transistor to establish a first reference current as its emitter current. A second transistor uses the first current as the reference to establish a second current value which has a positive temperature coefficient.  Third, fourth and fifth transistors use the second reference current to establish a third reference current value independent of the gain values of these transis-tors.  In the embodiment of the invention described, the third reference cur-rent is used to establish a reference voltage stable with respect to variations in the power supply, transistor gain and resistivity fluctuations of the cir-cuit but with increasing voltage as a function of temperature.  This voltage variation is used in combination with a load to cancel the effect of the load variations with temperature by providing an increased source voltage as a function of temperature.

Abstract: 22,490 APPARATUS FOR SIGNALLING SYSTEM       ABSTRACT OF THE DISCLOSURE     Apparatus for a signalling system.  The signalling system includes a remote control unit arranged to com-municate with a centralized communications center.  The remote control unit operates at or following a speci-fied time of day to initiate a self-check call and to communicate data to the communications center.  The communications center includes a disc unit which stores therein self-check timing data specifying the time of day at which the remote control unit is scheduled to initiate a self-check call.  A computer at the commun-ications center receives data from the remote control unit and operates in response thereto to update the self-check timing data in the disc unit to specify the time of day at which the next self-check call is to be initiated by the remote control unit.  In the absence of data from the remote control unit, there is no up-dating of the self-check timing data.  On a regular basis, the self-check timing data in the disc unit is compared with time-of-day data produced by a clock and representing the present time of day.  In the event the self-check timing data in the disc unit specifies a time of day earlier by more than a predetermined amount than the present time of day, the computer operates to produce an output condition indicating a missing or late self-check call.  The output conditions may be used in the preparation of a hard-copy printout for maintenance purposes.

Abstract: A b s t r a c t The opening and closing device permits simultaneous opening of for instance 100 m long roof hatches. Gear wheels are permanently mounted in housings on a transverse driving shaft at regular intervals. The gear wheels drive their respective rack for simultaneous displacement of the entire window. The cogs of the gear wheel have a larger width and are thin compared to the corresponding measure-ments of the rack cogs. In order to ensure the gear wheel mesh the rack comprises supporting surfaces engaging the cylindrical surfaces of the gear wheel and support rolls.          This device ensures that the racks hinged to the window frames may be displaced along or turned about their engaging points with the gear wheel without disengaging said gear wheel, and in such a manner that squeezing is avoided in connection with the longitudinal stretching and shrinking of the shaft due to variations of the temperature.

Abstract: ABSTRACT        The invention is a process for the manufacture of substantially pore-free shaped articles from polycrystalline material, such as tungsten carbide, silicon nitride, titanium boride or silicon carbide, in which encased articles preformed from pulverulent materials and having open pores are isostatically hot-pressed in a vacuum-sealed casing of vitreous or ceramic-like material in a high-pressure autoclave using an inert gas as pressure-transfer medium. Before the application of the casing material, a first layer comprising material that can be decomposed or melted, such as an organic wax or a resin-like product, or of a compressible heat-resistant material such as inorganic fibers or felts, is applied to the preformed articles.  Then, the encased articles are thermally treated until the glass or ceramic layer is fused or sintered gas-tight.  The articles pretreated in this manner are then isostatically hot-pressed.
