Abstract: MANUFACTURE OF AN OPTICAL FIBRE PREFORM WITH MICRO-WAVE PLASMA ACTIVATED DEPOSITION IN A TUBE Abstract of the Disclosure For making a preform for production of optical fiber, the preform including fused silica, particulate material is deposited on the inside wall of a glass tube while the tube is reciprocated through a microwave cavity for production of a plasma in the tube.  Oxygen and a reactant gas containing silica is passed through the tube.  Dopant material can be added to the gas mixture and the concentration of the dopant varied to vary the refractive index.  After the deposit of a sufficient thickness of particulate material it is fused.  The material can be caused to fuse on to the inner wall of the tube or to shrink away from the inner wall and removed from the tube.  When the material is fused onto the wall of the tube it can then be collapsed, then either drawn to a fiber or placed in a further tube and drawn to a fiber.  When the fused material shrinks from the tube wall, then it is collapsed to a solid rod, placed in a tube and then drawn to a fiber.     - i -

Abstract: ABSTRACT           MANUFACTURE OF CABLE BELTS The invention relates to the manufacture of a cable belt of a type that includes a plurality of parallel cables embedded in a polymeric compound, the cables extending throughout the length-wise direction of the belt and being spaced apart from one another in the trans-verse direction of the belt.  In the specific cable belt to which the invention relates the longitudinal center-line of the belt differs from the longitudinal centerline of the equipment on which it is to be produced, and the belt cables are tensioned by a tensioner that is position-ed between a cable let off and a spacing comb, the spacing between adjacent cables of the belt being different at the tensioner from that at the comb.  In order to reduce asymmetry of tension of the cables, the proper edge of the belt is determined along with the effective number of cables from the proper edge at the tensioner.  The effective number of cables are positioned to extend from tensioner positions nearest the proper edge to comb posi-tions distributed substantially equally about the longi-tudinal centerline of the belt, and one-half of the remaining cables of the belt are positioned transversely at the comb an effective number of spaces towards the proper edge.

Abstract: ABSTRACT OF THE DISCLOSURE           A resistive fluid or boiler water type of detecting system has been disclosed.  A single conductor type of probe having a plurality of conducting regions that are capable of conducting a bidirectional electric current in either a full bidirectional mode or in a unidirectional mode has been disclosed.  The single probe element is capable of three separate and distinct states of operation.  The first state is when there is an absence of current, the second is when there is a unidirec-tional portion of the bidirectional current flowing, and the third state is when the full bidirectional electric current is allowed to flow.  An output device is responsive to these three states to provide different types or levels of control.

Abstract: PEAK DETECTION AND ELECTRONIC COMPENSATION OF D.C. SATURATION MAGNETIZATION IN CURRENT TRANSFORMERS USED IN WATT HOUR METER INSTALLATIONS            ABSTRACT OF THE DISCLOSURE           A watt hour meter installation is described which is of the type including an input transformer having an input winding for connection to an alternating current power supply line, an output winding for connection to a watt hour meter for measuring alternating current power being consumed and a core on which the input and output windings are wound.  The core is of the type which is susceptible to DC magnetization by a DC component superimposed on the alternating current being measured. In order to overcome the effect of the DC component on the magnetization characteristics of the input transformer, automatic compensation circuitry is provided which includes a sensor coupled to sense the current flowing through the input winding and for deriving a sensed output signal proportional to the sensed current and which includes both AC and DC components of the input current.  A sensed signal processing circuit is provided in the form of positive and negative peak voltage detecting and holding circuits together with a summation circuit and voltage to current converter for deriving from the sensed signal a feedback signal which is proportional only to the DC component of the current flowing in the input winding.  This feedback signal is supplied through a compensating winding wound on the input transformer core in a direction to automatically cancel out the effects of the superimposed DC component on the saturation characteristics of the input transformer.

Abstract: ABSTRACT OF THE DISCLOSURE       A probe thermostat is disclosed having a positive-off element included in the switch portion of the thermostat which prevents the switch from being closed when the variable control means of the thermostat is set to its extreme or "off" position.  The positive-off element assures that the switch will be open even if a malfunction occurs in the thermostat which would otherwise result in closing of the switch and undesirable current flow to the heating element.  The illustrated form of positive-off element comprises an insulative threaded fastener attached to a portion of the base of the thermostat which engages one of the contact arms to hold it away from the other contact arm when the variable control means is set to its extreme "off" position.
