Abstract: Abstract:         The present invention relates to a network hub element for a star configuration optical network for transferring data among a plurality of data handling stations each connected by a transmission unit to the hub.  The hub is comprised of a receiver which is comprised of an optical combiner for additively combining the optical signals received from the transmission units for receiving serial data streams from the stations.  A transmitter is provided for transmitting signals to the stations.  A data transfer unit is coupled to the receiver and the transmitter for monitoring the data contents of the combined data stream as it is transferred from the receiver to the transmitter.  The transfer unit is responsive to the monitored data for selectively generating signals at the transmitter for transmission to selected ones of the data handling stations.

Abstract: ABSTRACT OF THE DISCLOSURE    Described is a method and a recording apparatus whereby audio and video signals can be recorded on a plurality of recording tracks on the same recording medium.  A series of temporarily consecutive audio signals can be recorded across a plurality of tracks.  On at least the audio track, information signals including the leading track number, the next following track number and the number of the video track bearing the corresponding video signals, are recorded.  The track number data of the information signals on these audio tracks are written in corresponding positions of a digital, table memory.  These control code data are recorded on a predetermined control track on the recording medium such that a series of desired audio signals and the corresponding video signals can be selectively reproduced smoothly and promptly by first reading the control track and then reproducing the audio and video tracks in accordance with the control code data information.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to sealing and support bushings which are located between the manifold and the mold back plate to encircle each valve pin in a multi-cavity valve gated injection molding system.  Each bushing is bolted through the manifold to a respective heated nozzle with central bores in alignment to receive the valve pin ltherethrough.  The bushing has an outer flanged portion which extends to contact the mold back plate and forms a leakage containment chamber between them.  Thus, the bushings retain the manifold in place, seal against substantial melt leakage around the reciprocating valve pins and collect any melt which does escape to prevent it entering the insulative air space between the hot manifold and the cooled mold back plate.  Location of the bushing between the manifold and the mold back plate also enables the use of a standard manifold having longitudinal and transverse bores without requiring diagonal bores.

Abstract: "Satellite Communications System with Random Multiple Access and Time Slot Reservation ABSTRACT OF THE DISCLOSURE        A multiple access data communication system is disclosed wherein a communication channel is shared by a plurality of stations.  The channel is divided into frames each being partitioned into time slots smaller in number than the number of stations of the system.  A reservation status signal is constantly broadcast at frame intervals from a central station to all remote stations to indicate reserved status of the time slots.  When a transmission request is made in a remote station, it discrimates a message signal shorter than the time slot length as a single packet having a time slot length and detects an idle time slot from the channel using the reservation status signal. If the message signal is longer than the time slot length, the station divides it into a series of packets of the time slot length and transmits a reservation request to the central station to receive from it a time-slot assignment signal and inserts the long-message packets to time slots specified by the time-slot assignment signal.

Abstract: LOW-LOSS SILICA OPTICAL WAVEGUIDES          Abstract Certain dopant materials, when present in a significant power-carrying portion of a silica-based optical waveguide fiber, are effective as intrinsic loss reducing agents; the concentration of such dopant materials is at significantly lower levels as compared with levels used for producing a refractive index difference.  Suitable in this respect are germania and phosphorus pentoxide as added to essentially pure silica or to silica containing other dopant additives such as, e.g., alumina or fluorine as may be used in a waveguiding core-cladding structure.  Intrinsic loss in the vicinity of 0.2 dB/km is readily realized.

Abstract: ABSTRACT CONTINUOUS EXTRUSION OF METALS         A continuous extrusion machine in which feedstock is admitted (at 50) to a peripheral groove (12) in a rotating wheel (10), is enclosed in that groove by a cooperating shoe (24), and is frictionally dragged along the arcuate passageway (48) formed by said groove and a projecting portion (30) of said shoe towards an abutment (36) carried by the shoe.  The pressure in the metal in front of the abutment continuously extrudes a metal product through a die (42).  The abutment tip and adjacent wheel parts disposed downstream of the abutment are cooled directly by a jet of cooling fluid issuing from a nozzle (64) carried downstream on the shoe.  An annular band (Figure 2, 74) of a good thermally-conductive metal embedded concentrically in the wheel enhances the cooling obtained.  Flash (68) extruded through clearance gaps (32, 34) between cooperating wheel and shoe surfaces is intercepted and broken off periodically, in short lengths, by teeth 70 projecting from the wheel.  The radial depth of the passageway (48) progressively decreases in the direction of wheel rotation in a zone extending upstream from the abutment (36), so as to improve in that zone, in the case of particulate or comminuted feedstock, the metal flow pattern adjacent the abutment, such feedstock in that zone being in a fully compacted condition without voids. This is achieved by the shaping of a surface (40A) of a die block (40) which adjoins the abutment (36) and incorporates the die member (42).  That shaping produces with particulate or comminuted feedstock a metal flow pattern closely resembling that achievable with feedstock in solid form.  A continuous extrusion product (Fig. 5, 102) issuing from a continuous extrusion apparatus (Fig. 1, 10; Fig. 5, 100) is threaded through e treatment die (104) whereby to change its cross-section and is continuously drawn there through by a tensioning device (106,112) under the control of a system which (a) sense the temperature of the product (102) as it leaves the extrusion apparatus (100); (b) converts a temperature signal (120) so produced, in a function generator (124), into a tension reference signal (126); (c) compares with that tension reference signal a tension feedback signal (116) derived from a sensor (118) adjacent the extrusion apparatus; and (d) controls the tensioning device in accordance with the difference of the tension reference and feedback signals so as to prevent the sensed tension in the product extending between the extrusion apparatus (100) and the treatment die (104) from exceeding a safe value which is less than the yield tress tension of that product at the sensed temperature.

Abstract: Process for preparing stabilised erythrocyte prepns. (I), wherein blood (e.g. from rabbit, rat, dove, sheep, chicken, man, etc.) is mixed with an isotonic anti-coagulant, centrifuged, and the erythrocytes washed with neutral buffer. They are then suspended in neutral buffer (>10 vols.), treated with propan-1-al-2-one (1 vol.) overnight, washed, resuspended, treated with formalin (1 vol) and again washed. The erythrocytes may then be stored for a long time below 4 deg. without agglutinating or haemolysing spontaneously. This treatment has no noticeable effect on the normal immunological properties of the erythrocytes. - The erythrocytes may also be activated by treating with suitable antigens, pref. 1-24 hrs. at 24 deg. and pH3.6-7-0. Both activation and stability are improved by cooling to - 190 deg., and storing subsequently at -20 deg. for 16 weeks, by cycling for 6 weeks from -20 deg. (6-7 days) to +24 deg. (a few hrs.), or by treatment with NaIO4. Alternatively, activation may be carried out by fibrinogen treatment. The products can be stored at -190 deg. or freeze dried, until required. - Haemagglutination tests for detection and determination of gamma-globulins, bacterial and virus infections, histocompatability, auto immune diseases, and for assay of antigens.
