Abstract: ABSTRACT OF THE DISCLOSURE         A portable electric lamp.  The lamp has a body including a lens, a lens holder, a reflector, and a bulb holder connectable through a switch with a source of electric power.  A translucent diffuser sleeve is co-axial with and surrounds the bulb holder.  The sleeve is asso-ciated with a drive so that it may be moved axially relative to the bulb holder between a retracted position at which a bulb held in the bulb holder is arranged to direct a spot beam through the lens and a forward position at which light from the bulb is diffused by passage through the diffuser sleeve.  The lamp can provide a beam of light and a spread of light for local work.  It is particularly useful in mines.  It may be mounted on a cap or safety helmet or held in the hand.

Abstract: Abstract of the Disclosure An output frequency of a first variable frequency oscillator is frequency-divided and the frequency divided signal is compared in phase with the output frequency of a reference frequency oscillator.  The result of the phase comparing is fed back to the first variable frequency oscillator for controlling the output frequency of the first variable frequency oscillator.  The output frequency of a second variable frequency oscillator is mixed with the output frequency of a fixed frequency oscillator to produce a difference frequency between both output frequencies.  The difference frequency is compared in phase with the output frequency of the first variable frequency oscillator.  The result of the phase comparing is used for controlling the output frequency of the second variable frequency oscillator.  The output frequency of the fixed frequency oscillator is frequency-modulated by the frequency of a modulating signal.  The result is that, even when the frequency of the second variable frequency oscillator is greatly changed, a stable frequency modulated wave is obtained from the second variable frequency oscillator.

Abstract: PATENT APPLICATION       of LOUIS T. ZITELLI and WILLIAM L. BEAVER                for ULTRASONIC IMAGING SYSTEM            ABSTRACT      An electrical-to-acoustic wave transducer contains an array of piezoelectric elements connected to wave delay circuits to generate a directed acoustic beam and to receive a  similarly directed, reflected beam.  The distance of a reflecting object is sensed by the time delay of the reflected wave.  The apparatus is adapted to sense reflections from both the Fresnel region and the far-field of the array.  During the time when reflections from nearby objects in the Fresnel region are received, the effective aperture of the array is reduced by disconnecting elements near its extremities or reducing their gain, producing a narrower beam for improved angular resolution.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to truss rod assemblies for adjust-ing the curvature of the neck of a musical instrument.  A number of prob-lems have been encountered in use of truss rod assemblies of the prior art.  The central portion of the fill strip is normally required to be very thin which creates the possibility of it cracking in handling and failure in use of the instrument.  More importantly, the cylindrical truss rods of the prior art are not very flexible, making the assembly procedure for the instrument difficult to accomplish.  According to the present invention, these problems are solved in a manner unknown hereto-fore.  With the present invention, it is possible to increase the thick ness of the fill strip at the center thereof to minimize the possibility of cracking same during the handling thereof and the possibility of failure thereof during use.  Furthermore, with the present truss rod assembly, the flexibility of the truss rod is substantially increased so that the truss rod more readily conforms to the curvature of  the slot in the instrument neck, highly simplifying manufacturing procedures and increasing the reliability of the finished product.  Briefly, the present improvement in a truss rod assembly consists of flattening a major part of the central portion of the truss rod to increase the flexibility thereof in the plane of curvature thereof.  Initially, the entire truss rod is cylindrical and the central portion thereof  is flattened in a press.

Title: Bland vegetable protein products and method of manufacture
Inventor: CAMPBELL MICHAEL F
IPC: A23L5/20

Granted: 1981-06-16
Abstract: BLAND VEGETABLE PROTEIN PRODUCT      METHOD OF MANUFACTURE     ABSTRACT An improved, commercial scale solvent extraction and desolventizing process for making bland vegetable protein concentrate which removes substantially all flavor-bearing substances from the concentrate, provides a nitrogen solubility index (NSI) of about 6-15 and a water absorbency of the concentrate in the range of 270-350.  The resulting vegetable protein concentrate is highly suitable as a protein extender for frankfurter sausages, braunschweiger and other prepared meats.  The subject vegetable protein concentrate is also useful in many other protein-containing foods including simulated meats, cereals, baked goods and snacks.     The process includes extracting defatted vegetable protein flakes with an aqueous alcohol solution to remove soluble carbohydrates and flavors, and thereafter slowly desolventizing the alcohol-extracted product in a humid gas atmosphere at a relative low gas temperature of less than about 180°F (82.2°C.) for about l-6 hours.  The resulting, desolventized vegetable protein concentrate is very bland, light-colored and is an economical protein extender for prepared meats which blends well and has no adverse effect on the texture or flavor of the blended products,  The low temperature, fluidized bed desolventizing preserves the desirable properties obtained by the above solvent treatments and removes substantially all remaining solvent from the bland product so that the product usually contains less than .2% (2000 ppm) residual alcohol, and preferably less than .1% (1000 ppm) alcohol.     The process has primary application to vegetable protein concentrate derived from soybean.  Other potential vegetable protein raw materials include rapeseed, sesame seed, safflower seed, cottonseed, sunflower seed, peanut, maize, yellow field pea, horse bean.
