Abstract: A method of forming a polymer-reinforced paper which includes preparing an aqueous suspension of fibers, at least about 50 percent, by dry weight, of which are cellulosic fibers; distributing the suspension on a forming wire; removing water from the distributed suspension to form a paper; and treating the paper thus formed with a polymer-reinforcing medium which contains a bulking agent to give the polymer-reinforced paper. The treatment of the paper is adapted to provide in the polymer-reinforced paper from about 15 to about 70 percent, by weight, of bulking agent, based on the dry weight of the cellulosic fibers in the paper. Alternatively, the bulking agent can be added to a polymer-reinforced paper after it has been formed. In certain embodiments, the bulking agent is a polyhydric alcohol. In other embodiments, the bulking agent is a polyethylene glycol having a molecular weight in the range of from about 100 to about 1,500.

Abstract: A tackle box rod holder including a generally cylindrical tube portion having a first and second end and means for connecting the tube portion to a tackle box for secure and fixed attachment without interfering with the normal swingable operation of the tackle box.

Abstract: A pile driver operated by a pressure supply of compressible fluid has a cushioning fluid chamber for transmitting the driving pulses to a pile. Both the cushioning chamber and the working chambers for generating the driving pulses are connected to an enclosed space from which the exhaust flow of fluid is able to escape by way of muffler means. The cushioning chamber draws in air at or near atmospheric pressure by way of said space which is in permanent communication with the exterior through the muffler means.

Abstract: An electronic control arrangement for a sewing machine with a frame having access openings at the top and bottom thereof and supporting therein functional mechanical and electromechanical and electrical sewing machine components. The electronic control arrangement includes a control panel disposed over a portion of the top access opening and interconnected with printed circuit boards having electronic components thereon for regulation of the electromechanical sewing machine components, the entire arrangement being organized to be removable as a whole for replacement or substitution from the top access opening. Means are provided accessible from the bottom access opening to removably support the control arrangement at the bottom thereof and provide a heat sink therefor.

Abstract: A fuel pumping apparatus comprises an injection pump including a cam angularly movable to vary the timing of injection of fuel, the cam being operated by a servo-mechanism which is controlled by an electrical torque motor. The supply of electrical energy to the torque motor is controlled by a control circuit which receives signals indicative of the speed of and the load on the engine, and also a signal from a transducer indicative of the actual timing of injection of fuel to the engine and also a signal from a transducer indicating the position of the parts of the engine. The control circuit processes the signals to provide for variation in the timing of injection of fuel in accordance with the speed and the load, and also checks that the actual instant of injection is correct.

Abstract: A nonmagnetic supporting member is adapted to surround a picture tube neck portion and includes a first collar having a plurality of circumferentially spaced cam-receiving apertures and a captivating collar spaced from the first collar, the supporting member including a clamp arrangement for fixedly mounting the member to the tube neck. A plurality of rotatable magnetized rings are mounted adjacent to the captivating collar and a rotatable second collar is mounted between the magnetized rings and the first collar. The second collar includes a plurality of ramp portions which, when rotated by tabs located on the first and second collars to locate the ramps within the apertures, unlocks the magnetized rings to enable adjustment. A second set of tabs formed on the first and second collars permit rotation of the ramp portions out of the apertures which increases the pressure on the magnetized rings between the captivating and first collars for effectively locking the rings in position.

Abstract: A deflection yoke includes a core having front and rear grooved end caps for securing conductor turns at the front and rear of the yoke. A third set of conductor grooves is disposed on the inside of the core at a position between the front and rear end caps for securing conductor turns at that position for forming precision-disposed non-radial active turns. The coils formed by the conductor turns may be toroidal or saddle, depending on the return conductor disposition.

Abstract: A heat sink arrangement for a circuit board in a sewing machine which supports the circuit board for ready disassembly therefrom, and makes use of the sewing machine frame as an additional heat sink. The circuit board is riveted to an aluminum heat sink member which carrys the power transistors in a manner to provide good thermal conductivity thereto but electrically isolated therefrom by mica laminae. An aluminum bracket firmly affixed to the sewing machine frame for good thermal conductivity has a large area planar surface thereof contiguous a similar large area planar surface of the heat sink member. A clamp member which extends through a slot in the bracket has a pair of upstanding arms with reentrant angles which touch the surface of the heat sink member opposite the large planar surface. The surface of the bracket opposite the large planar surface is formed with a cylindrical surface at an angle to coact with a cone pointed screw carried by the clamp member.

Abstract: A distributor type fuel injection pump includes an injection pump to which fuel is supplied from one end of a bore accommodating a slidable shuttle. The shuttle is moved towards the one end of the bore during the filling strokes of the injection pump by way of a first valve means and is allowed to move away from said one end of the bore during an interval between the filling strokes of the injection pump by fuel under pressure derived from the outlet of a feed pump by way of a second valve means. An electrically operable valve is provided to limit the amount of fuel which can flow from said other end of the bore and a sensor is provided to detect the position of the shuttle within the bore and which by way of a control circuit actuates said electrically operable valve. A third valve means is provided to admit fluid under pressure to said other end of the bore when it is required to fill the injection pump.

Abstract: In a telephone switching system wherein a plurality of line circuits are terminated in station sets, the line circuits are interconnectable to a plurality of trunk circuits through a multistage switching network. A call originated by a calling party to a called party, engaged in a conversation with a third party, is completed at the conclusion of the conversation between the called party and the third party by ringing back the calling party provided the calling party is equipped with the class of service which permits executive ringback. The ringback feature is initiated by the calling party upon receipt of a busy tone by a flashing of his switchhook.

Abstract: In a telephone switching system wherein a plurality of line circuits are terminated in station sets, the line circuits are interconnectable to a plurality of trunk circuits through a multistage switching network. A call originated by a calling party to a called party, engaged in a conversation with a third party, is completed by overriding the conversation between the called party and the third party provided the calling party is equipped with a class of service which permits call override. Call override is initiated by the calling party upon receipt of a busy tone by a flashing of his switchhook.
