The specification and drawings disclose an apparatus for dispensing a fine dispersion of grease into the interior of baking pans. The disclosed apparatus comprises a continuous screen belt which moves above a conveyor on which the pans are traveling. Above one run of the belt is an air chamber from which high-velocity, short-duration air jets are directed downwardly through the screen. The air jets are laid out in a pattern generally corresponding to the shape of the interior of the baking pans....

A screen printed capacitor to provide a predetermined temperature coefficient of capacitance. The capacitance device utilizes a common electrode with a uniform dielectric layer in conjunction with two side-by-side base electrodes resulting in opposite polarity temperature coefficient of capacitance values. The proportion of the area of each of the side-by-side base electrodes with respect to each other determines the predetermined temperature coefficient of capacitance required.

A calibrated torquing wrench that can be set to a predetermined value and upon reaching this torque by the rotation of the wrench will release the gear (28), spring (34) engagement and will allow the wrench to free-wheel for a small angle before re-engagement of the gear (28) and spring (34). The wrench will then endlessly rotate and repeat the predetermined value without exceeding the setting.

A support frame (10) for a plurality of predetermined characters (24A-24G) removably mounted in openings (22A-22G) of associated holders (20A-20G). The holders (20A-20G) are press fitted within a generally rectangular opening (14) of an outer frame member (12). Tongue and groove combinations (21, 26) retain holders (20A-20G) within the outer frame member (12). The characters (24A-24G) may comprise alphabetical letters, numerals, or various symbols.

A predetermined separation fitting for a fluid conduit includes a body and walls in the body defining a predetermined separation point. A force applied to the body above a predetermined value will cause the fitting to separate.

A process for the production of a composition modulated alloy having a predetermined concentration is disclosed, in which alternating layers of at least two metals are successively deposited upon a substrate by electrodeposition, vacuum deposition, vapor deposition, or sputtering. The individual thicknesses of at least one metal's layers are varied in a predetermined manner. Pulsed galvanostatic electrodeposition using a tailored waveform is preferred. A copper-nickel concentration graded alloy ...

An endodontic instrument for use in root canal therapy which comprises an inner core of a metal having a specific flexibility, and at least one outer shell of a metal having a different flexibility. By selecting the ratio of the two metals, the instrument may be designed to have a predetermined desired flexibility which is sufficient to assure proper operation of the instrument, yet not so stiff as to risk damage to the tooth canal. A kit which is composed of several such instruments of increasi...

A method by which certain material on a master can be reproduced while suppressing reproduction of other material on either the master or copy paper in xerography or like processes. The method uses a master which has the material to be copied printed in light absorbing ink, while the material on the master or copy paper to be suppressed during copying is printed in transparent ink. As examples, the master or copy paper can have background material or instructions printed in colored transparent i...

A differential amplifier, having a first and a second transistor, each transistor having two series-connected resistors connected to the collector, and having two output transistors; one of the output transistors having its base connected through a temperature compensating diode to the junction of the two resistors which are connected to the collector of the first differential amplifier transistor, and having its emitter connected to the collector of the second differential amplifier transistor;...

The clamp with predetermined clamping force disclosed herein is provided with first and second opposed wires having hooks thereon for engagement through aligned holes in sheet material intended to be clamped. A tee is extendable relatively to the wires between the wires to engage the hooks at the edges of the holes. The clamp body engages the sheets opposite to the hooks so that the force by which the hooks are pulled into the body is the sheet clamping force. This force is created by stressing ...
