Abstract: ABSTRACT OF THE DISCLOSURE    A communication system includes a device connected to a line through a hybrid coil and performing the transmission/reception of data and voice from and/to an opposite device.  A switching relay of a voice transmission/voice reception in the device is controlled by a control data from the opposite device.  The control data is sent out a plurality of times and after detection in a data detecting portion, a continuous transmission check is made in a continuous transmission checking portion.  In the device, a connection of data detecting portion and the line and a connection of a microphone and the line are alternately disconnected by a relay, so that a detection of data is made only when the transmission of voice is interrupted.  The disconnecting relay is driven in response to a pulse of a predetermined duty ratio.  If and when the first data is detected in the data detecting portion, a monostable multivibrator is triggered so that the disconnecting relay is maintained in condition that the detecting portion and the line are connected in response to the triggered output.

Abstract: ABSTRACT OF THE DISCLOSURE A mounting structure for resonators used as frequency standards and transducers which maximizes performance and reduces the sensitivity to environmental errors.  In one embodiment, force sensitive resonators having inherent unmounted temperature sensitivities are used in conjunction with reactive spring-like mounting arrangements having predetermined temperature stress characteristics such that the thermally induced mechanical stress of the mounting arrangements changes, compensates, and optimizes the overall combined temperature characteristics.  In another embodiment resonators are isolated from the external enviroment so that they are capable of sensing forces while operating in a vacuum or inert atmosphere.  Enviromental isolation is provided by bellows and/or diaphragm arrangements used along or in conjunc-tion with air-tight enclosures which enable forces to be applied to stress-sensitive resonators while isolating the resonators from the external force producing enviroment.

Abstract: Abstract Optical Parametrons A computing system is disclosed including a new optical parametric logic gate.  The parametric logic gate includes an optical resonant cavity having nonlinear optical characteristics, such that the cavity will generate a subharmonic output signal having a frequency f when supplied with a pump frequency of 2f.  The subharmonic output signal may have one of two possible phases which differ by ? radians to one another, and correspond to binary 1 and 0 respectively.  A bias signal having a frequency f is supplied to the resonant cavity.  Optical input signals are summed with the bias signal to produce a resultant seed input signal having one of the two phases.  The phase of the seed input signal is imparted to the phase of the output subharmonic.  The type of logical operation which the parametron performs can be controlled by adjusting the power of the bias signal. The subject disclosure also includes a description of computing systems having various pump arrangements. In addition, data input/output interlaces are disclosed.

Abstract: A B S T R A C T     A lamp carriage arm, adapted for attachment to a safety hat, is disclosed. The lamp carriage arm offers improved lighting for miners and other workers by virtue of the lamp being positioned roughly in the area of below the safety hat wearer's eye level and above and in front of the safety hat wearer's collarbone. The lamp carriage arm attaches at one end to one side of the safety hat, and extends downwardly in spaced relationship to the side of the safety hat wearer's head. Conventional lighting, e.g. a miner's lamp, is carried at the other end of the lamp car-riage arm. Preferably, the attachment of the lamp to the carriage arm is pivotal, so that the direction of the lamp beam may be varied. Thus the use of a ball and socket joint is disclosed, although other means may be employed. Adjust-ment means for varying the position of the lamp are also disclosed.

Abstract: ABSTRACT A battery feed circuit for a two wire telephone subscriber line is miniaturized by electronic integrated circuit (IC) without transformer. The electronic battery feed circuit is composed of first and second operational amplifiers, output resistors, a DC voltage feedback loop, an AC signal feedback loop, and a switching power supply.  The switching power supply is to control power source voltage of the first operational amplifier, corresponding to the length of the subscriber line loop and the status of a telephone set in the loop.  Low power consumption of the circuit is attained as follows.  Firstly, the losses in the output resistors are reduced by using small resistances and the loss in the second amplifier is reduced by using a small DC bias.  The loss in the first amplifier is reduced by lowering its power source voltage to a level lower than its output voltage by the switching power supply.  The switching power supply is composed of a zener diode, two comparators and a switching transistor circuit.

Abstract: ABSTRACT OF THE DISCLOSURE       A power plant is disclosed in which a steam turbine/ coal-fired steam boiler is integrated with an air turbine via using the convection section of the boiler to heat compressed air for the turbine, by indirect heat exchange with the flue gas, the hot turbine exhaust being sent to the boiler as preheated combustion air.  In this way, only clean air reaches the turbine and not combustion products which would result from direct firing of fuel in compressed air whereby coal may be burned instead of premium quality fuels.  Platens in the radiant section of the boiler are used both to regulate flue gas temperature and take over some of the usual convection section services to release it for compressed air heating service.

Abstract: ABSTRACT               In an impressed current cathodic protection system for a boat and/or its propulsion system the boat battery is connected to a switching type power converter which supplies the anode higher current at lower voltage than taken from the battery.  The voltage on the anode is regulated to be constant or to be fixed relative to the voltage at a reference half cell.  With either arrangement, the voltage drop across a reference resistor can be applied to an op amp to turn on a transistor to connect an alternate power source to the anode.  The voltage across the resistor is regulated by the power converter chip so the chip also regulates the alternate source to prevent excessive voltage on the anode.

Abstract: "PROCESS FOR PRODUCING HIGH PURITY BUTENE-1 WITH A LOW         ENERGY CONSUMPTION"                       Abstract High purity butene-1, in particular polymerisation grade butene-1, is obtained by means of the two-stage fractionation of a C4 hydrocarbon stream which contains it, substantially free from butadiene.       The first stage of the fractionation process allows practically all the isobutane contained in the C4 batch to be separated as the top stream.       The bottom phase of the first stage of fractions-tion is supplied to the second stage of fractionation thus obtaining high purity butene-1 as the top fraction, and the remaining components as the bottom phase.       A characteristic of the process according to the in vention is that the vapours of butene-1 obtained as the top stream from the second stage of fractionation are compressed; the heat of condensation is used for operat ing the reboilers of the two fractionation stages.

Abstract: Abstract Low Engine Oil Sensing Method A method for sensing when the quantity of oil in the crankcase of a reciprocating piston engine is inadequate for proper lubrication while the engine is operating.  During engine operation, the crankcase gas pressure cycles between positive and negative values as the piston reciprocates.  Positive crankcase gas pressures are vented though a check valve.  The resulting cyclic vacuum in the crankcase has a peak and average magnitude which is a function of the quantity of oil in the crankcase.  For a constant speed and substantially constant load engine, the crankcase vacuum can be used to indicate the approximate quantity of oil in the crankcase.  For constant or variable speed and load engines, a drop in the crankcase vacuum below a predetermined level can be used to automatically stop the engine prior to damage by inadequate lubrication.
