Abstract: A self-contained signalling device for insertion into a pipe of a drain system, such as a sewage system including a septic tank, the device being capable of emitting a signal, such as a pulsating sound, when the level of liquid in the pipe reaches a predetermined level.  The device includes an alarm portion which includes a circuitry having a power source and signal emitting component, such as a horn, and electrodes which cause activation of the signal emitting component when the electrodes are contacted by the liquid in a back-up condition.  The device further includes a member which carries the alarm portion and engages the pipe for holding the alarm portion in a preselected position in the pipe.  The device is designed to enable a householder to readily insert it in a pipe, such as in the floor drain, and from time to time remove it for battery replacement without accuiring the services of skilled personnel.  By properly placing the device in a floor drain pipe or inside of a clean-out opening, the householder is made aware of a failure in the sewer system and can then take action to prevent excessive damage which might otherwise be caused by the back-up reaching the stage of flooding a large area within the house.

The pulley device additionally includes a two piece sheave enclosing the outer race and the ring effective to place the ring under a compressive load whereby the main body of radial load on the pulley is transmitted to the bearing through the ring, resulting in the ring being com-pressed around the outer surface of the bearing assuring a firm, re-liable grip on the bearing, and while the sheaves are in contact with the end portion of the outer race of the bearing to maintain proper roundness of the bearing as precision ground.  A method of mounting a precision bearing in a sheave whose dimensions are less precise where the sheave is composed of two disc-like elements substantially identi-cal but of opposite hand comprising the steps of mounting an elastic ring on the outside diameter of the outer bearing race and compressing the elastic ring against the bearing race by bringing the disc-like elements together in face to face contacts so as to encircle the bear-ing and the ring.  The method additionally includes securing thereafter the disc-like elements together by riveting, bolting or the like.

Abstract: METHODS AND APPARATUS FOR ADJUSTING OPTICAL FIBER CONNECTOR COMPONENTS AND PRODUCTS PRODUCED THEREBY Abstract An alignment sleeve for holding two concially shaped portions of plugs each of which terminates an optical fiber includes two conically shaped cavities communicating through a common minimal diameter plane. After the sleeve has been molded, a tool faced with an abrasive material is inserted into each cavity of the sleeve and turned rotatably while a force is applied in a direction parallel to the longitudinal axis of the tool. This causes material to be removed from the walls defining the cavities so that when the two plugs are inserted into the cavities, the axes of the fibers will be aligned coaxially and the end faces of the fibers will have a predetermined separation.  The methods and apparatus of this invention also may be used to adjust a length measurement of plugs.  This is accomplished by inserting a plug into a conically shaped cavity of a tool.  A wall whcih defines the cavity of the tool is faced with an abrasive material which upon turning the plug abrades the plugs to thereby increase the distance from a reference circumference of the plug to a pedestal in which the free end of the optical fiber terminates.

Abstract: Abstract:         The present invention relates to a method of calibrating transmitting devices in a star configuration optical network which interconnects a plurality of data handling stations, where the network is a hub.  The method is comprised of the steps of adjusting a threshold detector in the hub to a predetermined level and adjusting the transmitting device of one of the stations connected to the network to transmit a signal of sufficient amplitude to exceed the predetermined level.  The method further includes the two steps of detecting signals exceeding a predetermined level in the network by the detector and adjusting the transmitting device of the one station to transmit another signal of a lower amplitude than the last previously transmitted signal.  The last two steps are then repeated until no signal exceeding the predetermined level is detected.  The threshold detector is then adjusted to a new level which is an increment lower than the predetermined level.  The transfer of signals through the hub is then inhibited for all signals below the new level.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention provides an approach for drilling offshore arctic wells in areas covered by floating ice. A grounded spray ice drilling structure having an inner drilling platform portion and an outer barrier portion which are contiguous is constructed by withdrawing water from beneath the ice sheet and spraying the water through the air when the air is below the freezing temperature of the water.  This causes the water to freeze into spray ice as it passes through the air.          The resulting spray ice is deposited on the ice sheet to build up the grounded spray ice drilling structure.  The outer barrier portion is built up to a greater freeboard than the inner drilling platform portion, and is adapted to laterally confine the inner drilling platform portion and to protect the inner drilling platform portion from natural ice forces.
