Title: Resealable closure device for encapsulating spliced  cables
Inventor: CHARLTON JOHN R
IPC: H02G15/10
Filed: 1981-01-15
Granted: 1983-07-05
Abstract: ABSTRACT OF THE DISCLOSURE         This invention discloses a new closure device for encapsulating spliced cables therein which are succeptible to atmospheric conditions.  The device comprises a main body filled with a curable, alcohol or alkoxy terminated silicone resin which is curable upon exposure to moisture and a cap for closing the container.  The device allows the installer to quickly and easily install the device in the desired location without mixing or measuring the components of the prior art resins.  Also, the device is not succeptible to atmospheric conditions as were the prior art devices and in fact, the resin will reseal itself to protect the splice of the spliced cables in the event that the body becomes distorted or damaged.

Abstract: A B S T R A C T        Fishing equipment has a tiltable arm on a standard.          A supply of line is led through a guide means below and a small amount inwardly of the outer end of the tiltable arm when the latter is in an horizontal attitude.  From the guide means the line is led upwardly and over a retaining means on the end of the tiltable arm.  From the retaining means the line hangs into the water.  The tiltable arm tilts under the pull of a fish on the line.  The retaining means is designed so that such tilt of the arm releases the line from the arm when it swings inwardly of the guide means.

Abstract: ABSTRACT OF THE DISCLOSURE     Magnetic recording medium conventionally utilizes the in-plane magnetization mode, but, recently, the perpendicular magnetization mode utilizing the perpendicular anisotropy of an hcp cobalt alloy layer, in which C axis is oriented normal to the layer surface, is proposed.  The known perpendicular magnetic recording medium has been produced by an RF sputtering, but such medium is of too low flexibility to use it in the form of a magnetic tape.  In addition, the production rate of the perpendicular magnetic recording medium by RF sputtering is very low.    The perpendicular magnetic recording medium is very flexible due to particle pattern (Figs. 10, 12 and 13) completely distinct from the conventional columnar pattern (Figs. 8 and 11).  In addition, the production rate is high, because the base (20) is located beside a space between the targets (T1 , T2) of a sputtering device and further the magnetic field is generated perpendicularly to the sputtering surfaces (T1s , T2s) by a field coil (31) or magnets (32, 33).  The present invention makes it possible to commercially produce the perpendicular magnetic recording medium, especially in the tape form.

Abstract: ABSTRACT:         The image contrast in an image display tube having a channel plate electron multiplier can be improved by preventing secondary electrons created on the outer face of the input dynode of a stack of dis-crete apertured dynodes from entering channels located at a relatively large distance from their origin. This is done by disposing a grid at a short distance from the input dynode. If the grid is held at a posi-tive voltage relative to the input dynode then stray secondary electrons will be attracted towards the grid. Alternatively by the grid being at a negative voltage relative to that of the input dynode then substantially all the secondary electrons will be induced to enter channels close to their origin thus contributing to the overall brightness of the image. Either way the image viewed is spatially correct.

Abstract: Abstract of the Disclosure A focusing current or voltage applied to a focusing coil or focusing electrode to focus an electron beam on a target of a camera tube is modulated by a modulation signal so that the focusing current or voltage varies between a maximum value and a minimum value with its average value as the center.  The focusing states of the electron beam at the maximum and minimum values of the modulated focusing current or voltage are detected by a video signal from the pickup tube.  Based on this detection of focusing states of the electron beam, the average value of the modulated focusing current or voltage is corrected in such a way that the focusing states of the electron beam become equal to each other which correspond to the maximum and minimum values of the modulated focusing current or voltage.  The correcting operation is carried out until the focusing states of the electron beam become equal at the maximum and minimum values, and the electron beam is -then focused by the focusing current or voltage corresponding to the average value in the state.

Abstract: INFUSION PUMP CONTROLLER                 Abstract of the Disclosure A closed loop medication introduction system controls the rate at which medication is introduced into a patient in response to a monitored physiological condition.  The system includes a monitor for monitoring the level or magnitude of the physiological condition and an infusion pump for introducing medication for controlling the selected physiological condition into the patient at a variably controllable rate.  A controller controls the infusion pump in response to monitored changes in the physiological condition of the patient.   A display means displays various information about the monitored physiological condition and the introduction of medication into the patient.          The controller produces a rate control signal for controlling the infusion pump in response to signals from the monitor.          After an increase in the medication introduction rate, the controller blocks subsequent increases until a sufficient time has passed for the patient to respond to the increase in the amount of medication. If during this time the patient's blood pressure stabilizes, the controller increases the time allowed for the patient to respond to the increased amount of medication.  If during this time the patient's blood pressure increases still further, the controller makes a small, interim rate increase.  If the patient's blood pressure decreases below the preselected level, the controller decreases the medication introduction rate.

Abstract: ABSTRACT                 COMMUNICATION SET AND METHOD      A telephone communication method provides simul-taneoulsy duplex channels between respective pairs of stations over a single wire pair highway by frequency division multiplexing.  Each duplex channel has a pre-determined pair of carrier frequencies, but only carrier frequency pairs of channels in use for communication are present on the highway at any time.  On initiating a call, a station seeks for a free channel and reserves it by generating the "go" carrier of the free channel modulated with the call sign of the desired station, and also generating an alert signal.  Quiescent stations respond-to the alert by seeking a "go" carrier with call sign data and, on identifying their own call sign, gene-rating the corresponding return carrier to set up the channel.
