A control circuit for the motor of an electric marine toilet which, effectively, causes the toilet to flush. A conventional D.C. source of potential is employed with a conventional marine toilet including a motor, a pump driven by the motor and a macerator driven by the motor. The lid of the toilet operates a normally open switch. An advantage of the invention is that the lid-operated switch prevents injury to the operator. Moreover, the lid-operated switch provides a motor control override. Tha...

A head includes a head chip, having first and second external connection electrodes, for reading a signal from a storage medium and writing a signal on the storage medium, a substrate having the head chip mounted thereon, a hot-side conductor path and a ground-side conductor path each formed on the surface of the substrate and electrically connected to the corresponding external connection electrodes of the head chip, and a chip varistor, mounted on the substrate, having first, second, and third...

A dredging apparatus having an improved dredging head in which the suction pump and drive motors for the same are mounted adjacent the clean-out and cutting augers for increased pumping efficiency. The augers include a cooperating plurality of cutting teeth mounted peripherally on the flighting of the auger and extending spirally along the same to provide for a continual shearing cutting surface in a line parallel to the rotational shaft of the augers for more efficient cutting of the fibrous ma...

A chin and cheek engaging head rest and holder is provided, intended primarily for use by beauty shop patrons while sitting under a fixed hair dryer. The chin and cheek engaging portion of the rest is desirably mounted on a chair arm with capacity for vertical, angular, lateral and tilting adjustments as a unit, and with provision for angular broadening and narrowing of the chin and cheek engaging portion of the rest, itself, to any desired extent within practical limits.

An apparatus and method for rotationally moving and positioning a work piece such as for dividing the workpiece into a predetermined number of equal segments. The movement is accomplished by repeatedly angularly displacing the work piece over a given swing increment of angular movement. The angular swing increment is established by summing angular displacements of each of a plurality of circular plates, each plate divided into a different number of equal segments. By a proper choice of the numbe...

The acoustic head is intended for ultrasonic measurement at non-destructive testing and quality control of solid bodies and articles. The herein disclosed head includes, in addition to an electromechanical transducer, e.g. a piezoelectric one, shock-damping means, protector and means for pressing the transducer to a test object, an electric motor (7) mounted in the housing (1) of the head, an eccentric (9) mounted on the shaft (8) of the motor and engaging the holder (3) of the transducer throug...

Ferrite recording head members are coated with a layer of silicon nitride prior to filling the gap between the members with nonmagnetic material. The silicon nitride coating protects the ferrite member from attack by the nonmagnetic material.

A shower head adapted to mix and dispense a detergent and water is disclosed. A rotational shaft with impeller blades mounted on one end and a rotary brush engaging a detergent bar on the other end is rotated in a shower head when water under pressure flowing through the shower head impinges on the blades. Means are employed to keep the rotary brush in contact with the detergent bar when the detergent bar is being consumed during use. Means for diverting water toward or away from the impeller bl...

A printing head provides an array of stylii and stylii drivers for forming characters in accordance with a desired matrix of dots. Each driver comprises a flat piezoelectric ceramic wafer and a levered beam having a stylus secured to one end and providing at the stylus end a multiplication of the movement of the wafer of approximately 4 to 1 to 7 to 1. The wafers and supporting structure are circular and structured to nest preferably coaxially, with each levered beam lying at a small angle relat...

This invention is directed to an improvement in die-heads and molds which are used in briquetting machines or presses for molding cylindrical briquettes from fibrous particles such as: wood particles, sawdust, wood shavings, paper, wood chips, and other fibrous materials. The die-head and the die for the briquette make it possible to achieve a briquette having a more uniform cross-sectional density and also a briquette of higher density than could be realized with prior briquetting machinery.
