Abstract: ABSTRACT OF THE DISCLOSURE     An electrically-heated, glass melting furnace with a cooling trough and with cooling means for the trough is provided.          The furnace is heated by means of electrodes immersed in molten glass in the furnace; particularly as the throughput of the furnace increases, the molten glass becomes hotter.  To overcome this, the cooling trough is provided in a portion of the furnace bottom, extending beyond a throat to a riser, with the bottom and the side walls of the trough being exposed to ambient temperatures below the furnace.  The resulting heat loss aids in cooling the glass flowing out of the furnace to overcome the inherent heat rise at high throughputs.  Cooling means are also provided extending along the trough, with the rate of cooling achieved thereby being capable of selective control.  Specifically, an air duct extends along the cooling trough and has outlets spaced therealong directed at the trough bottom to supply cooling air in heat exchange relationship with the bottom.  Electrodes also can extend upwardly through the trough bottom into the trough, the electrodes serving to further cool the trough by providing heat conductive paths from the trough to the ambient conditions below the furnace.  The trough electrodes, if desired, can also be heated by an emergency power supply to prevent glass from solidifying in the trough in the event that a major power failure should occur and power to the main heating electrodes is off.

Abstract: METHOD AND APPARATUS FOR MANUFACTURING   A THREE-DIMENSIONED CRIMP FILAMENT                ABSTRACT OF THE DISCLOSURE             A three-dimensioned crimp filament is prepared by twisting a bundle of large denier filaments into a single twist while said filaments are stretched between a freely-rotatable first roller with a peripheral groove having 10-500 mm of diameter at a grooved portion and at least one other freely-rotatable second roller in a total denier of 50,000 - 3,000,000 denier by means of twisting action in a subsequent double twist step, double twisting said single-twisted filaments into a double twist up to said first roller and heating the filaments thus twisted into a double twist while passing them through a tubular guide means, cooling said double-twisted filaments to effect a heat-set while maintaining the twisting action; untwisting said double-twisted filaments thus heat-set to form three-dimensioned crimp filaments, and cutting said untwisted three-dimensioned crimp filaments into staple lengths.  The diameter of the first roller at the grooved portion is correlated with the diameter of the double-twisted filaments formed to prevent the spread of the double twist back beyond the first roller, and the width of the peripheral groove and the diameter of the tubular guide means are sufficient freely to receive the double-twisted filament but insufficient to allow it to curl into a greater multiple twist.

Abstract: ABSTRACT       The device has a gas passage of adjustable flow cross-section through which gas flows in normal use.  Inflowing gas also acts on a blocking member, and when the pressure of the inflow gas rises above a certain value, the pressure on the blocking member is sufficient to move the blocking member into the gas passage to block the passage.          The blocking member is then retained in position in the passage, blocking the gas flow by the gas pressure.  The blocking member can be a ball which is moved against the force of gravity by the pressure of the gas to close the passage.

Abstract: POWER SUPPLY UTILIZING A HIGH FREQUENCY MAGNETIC AMPLIFIER     ABSTRACT        A regulated power supply includes an oscillating inverter circuit for generating a high frequency square wave signal that drives a saturable reactor which pulse-width modulates the square wave as a function of a control current through a control winding on the saturable reactor.  The output voltage generated by the power supply is sensed by a feedback circuit and fed back as a modulating signal of the control current through the saturable reactor control winding to vary the power transferred by the saturable reactor to an output transformer. The  variation in power supplied to the output transformer compensates the output voltage as sensed by the feedback circuit. A protective circuit is provided to sense an output overvoltage condition and inactive the power supply by terminating the oscillation of the inverter.

Abstract: Abstract The invention relates to frame synchronisation of time division multiplex systems which provides satisfactory insensitivity to simulation of synchronising features, without requiring an excessive channel trans-mission capacity.  According to the invention there is provided a synchron-isation apparatus for a receiving station for the reception of time divi-multiplex (t.d.m.) signals in the form of a series of t.d.m. frames each of m bits one of which is a synchronising bit and wherein a plurality p, where p is at least 6, of consecutive synchronising bits form a synchronising word. A synchronising word recognition device is arranged in operation to monitor the synchronising words and to recognise when such words conform to a predetermined bit pattern.  A monitor produces a synchronisation alarm for indicating lack of synchronism and is responsive to the recognition of two consecutive synchronising words to commence a test period the duration of which is at least one multiple of p t.d.m. frames and, if not reset, terminates, the synchronisation alarm at the end of the test period.  A reset device is responsive to failure to recognise a synchronising word during the test period to reset the monitoring means.  A synchronisation loss recognition device is responsive to failure to recognise a prcdetermin-ed plurality of consecutive synchronising words to reinstate the synchron-isation alarm signal.

Abstract: R. TREIBER - 5 Abstract of the Disclosure The present invention discloses a reduced power dissi-pation telephone subscriber line feed circuit in which the battery feed current from the central office is determined by the subscriber loop resistance for medium to long loops, and for shorter loops, for which the battery feed current would exceed a given predetermined threshold, the feed current is limited to the threshold value.  The invention also relates to compensation for loop and sunset attenua-tion characteristics.      During operation in the current limited mode, attenua-tion is automatically inserted into the signal transmission and receiving paths in order that normal equalizer operation will not be impaired by current limiting of the battery feed current.  A multiple telephone subscriber system is disclosed wherein the circuitry used in deriving current limiting control signals is shared in a multiplexed arrangement by a plurality of subscriber lines.  Line feed current is limited in discrete steps to a predetermined threshold value in each subscriber loop upon the detection of an OFF HOOK condition when the feed current drawn by the subset exceeds the thresh-old value.  A plurality of discrete signals are derived by sensing the amount by which the line voltages exceeds a predetermined selected reference voltage value.  These discrete signals are used to determine both the effective battery voltage which will produce a d.c. feed current corresponding to the limiting value and the amount of attenuation to be added at the central office by the line circuit to compensate for the equalizer effect in the subscriber set which occurs as a result of the current limiting.
