Abstract: ABSTRACT     A deep-fat fried expanded snack product is made from a moist dough according to a technique which prevents undue distortion of the snack during frying.  The dough can include cooked potato solids, masa, and/or one or more cereal flours, with a moisture content of about 35% to 60% at the time of frying.  An amount of ungelatinized starch can be present in the dough when fried.  In one embodiment, the dough is extruded as a pair of separate long, thin strands which are formed into a composite dough piece by adhering the strands by surface contact along the long dimension of the strands.  The two adherent strands can be straight solid dough pieces in side-by-side contact, or the strands can be twisted together to form a braid.  In another embodiment, a sheeted dough piece can be slit lengthwise along its center and partially through the depth of the dough piece to form the equivalent of a pair of adhering strands.  The composite dough piece is immediately fried following the forming step, producing an expanded finished snack that is essentially straight with a shape virtually free of distortion.  The strands in the composite dough piece, when fried, also expand more than if each strand is fried singly.

Abstract: INVENTORS: Klaus SCHLENSOG            Christian BEER Robert RIEDWEG INVENTION: BREAST PUMP     ABSTRACT            A breast pump for manual operation of the type comprising a receptacle that is put against the breast to surround a teat and has a variable enclosed volume in the manner of a cylin-der-and-piston-pump which when operated in contact with a breast causes the milk to be drawn into the receptacle due to the suction generated by an enlargement of the enclosed volume.            The tubular part of the hollow piston is tapered such that its upper end has a smaller outer diameter than its lower end that carries an annular lip seal; consequently, the out-er cylinder which is manipulated, i.e. moved to-and-fro re-lative to the hollow piston, can be tilted to some extent without concurrent tilting of the piston and the suction bell that is integrally connected therewith; thus, pump-induced motion of or at the sensitive area of teat and areola is min-imized for improved user comfort. The suction bell is arrang-ed at a predetermined angle with respect to the longitudinal axis of the tapered tubular part so that the outer cylinder can be held more nearly vertical when the pump is used in a normal sitting position; back-flow of the milk from the reser-voir to the breast can be reduced or ellminated.

Abstract: A B S T R A C T     The object of this invention is to provide a means of collecting and disposing of any waste matter deposited by natural means on a base such as a sidewalk, grass surface, snow, wooden walks etc.   This is accomplished by placing a plastic or similar type disposable bag over the waste matter and tightening the noose at the base which will separate the matter from the base and then it can be lifted and disposed of without touching with the hands or even bending over.    At this time the public is becoming increasingly aware of the problems of environmental pollution and more cities are introducing by-laws to restrict the exercising of pets in public streets, parks, beaches etc.    If an easy-to-use device were available for cleaning up after pets their owners would make use of it and reduce the problem of keeping public areas clean.    Until now, to the best of my knowledge, there have been no devices available to the public for this purpose which are simple to use, inconspicuous and hygienically acceptable.    In appearance this device is a walking stick-neat, sturdy and attractive. It is simple to use without soiling the hands or the device and does not even require bending over.    The disposable bags could be carried inside the handle of the stick and are thus readily available.

Abstract: Abstract of the Disclosure This invention relates to a temperature control indicator unit comprising a substrate having supported thereon (a) microcapsules enclosing a hydrophobic organic compound possessing an arbitrarily selected melting point, (b) a methine dye and (c) an oxidizing material.  More particularly, a unit made by combining an irreversibly color-developing methine dye and an oxidizing material with microcapsules enclosing a hydrophobic organic compound possessing a predetermined melting point and supporting them on a substrate is used f or temperature control purposes.  A suitable measure is taken, preferably at or below the desired control temperature to break at least a part of the microcapsules of the unit and thereby produce fissures or the like in the microcapsule membrane.  Then, the unit is stored or transported together with an article to be placed under temperature control.  As a result, if the article is exposed to temperatures exceeding the desired control temperature, the non-volatile organic compound present in the broken microcapsules melts and diffuses out.  This brings the methine dye into contact with the oxidizing material present in proximity thereto and causes an irreversible color development of the methine dye.          Thus, the occurrence of abnormal temperature control conditions can be detected by observing such color development.

Abstract: TITLE Apparatus and Method for Transferring a Bingham Solid through a Long Conduit Abstract Of The Disclosure An apparatus for injecting a lubricating liquid, e.g., water, into a conduit as an annular layer around a flowing Bingham solid, e.g., a water gel or water-in-oil emulsion explosive, to facilitate the flow of the Bingham solid has an annular passageway from which the lubricating liquid flows into a cylindrical chamber containing the flowing Bingham solid.  The annular passageway has a constricted throat portion of adjustable width, which, along with the flow rates of the Bingham solid and the lubricating liquid, is adjusted to produce a thin film of lubricant which allows lubricated plug flow of the Bingham solid in a descending section of conduit under the propelling force of gravity alone. Low drag permits the delivery of Bingham solid explosives into very deep vertical holes with no increase in the required pumping pressure.

Title: Tire uniformity grinder and method
Inventor: UGO JOHN W
IPC: B24B5/36
Filed: 1984-06-29
Granted: 1988-08-09
Abstract: The apparatus for improving tire uniformity includes contrarotating grinding wheels for removing tire material from the upper and lower shoulder portions of the tire. The grinders are moved into grinding engagement with the tire along a path that is defined by a radius of the tire to ensure that both grinding wheels at each shoulder of the tire make simultaneous contact with the tire. The amount and extent of grinding accomplished by the contra-rotating grinders is controlled by a grind control circuit. The grind control circuit measures the no-load current level of the grinder motor and compares the no-load current level with the current level when the grinder motors are under load. When the grinder current under load is above a predetermined maximum load current, the control circuit will signal the grinders to retract from engagement with the tire until the load current drops below the predetermined maximum level. When the motor load current is below the minimum operating range level, the grinders are signalled to advance into engagement with the tire until the load current reaches the predetermined minimum level. This operation is repeated in cyclic fashion until the tire has been ground a sufficient amount to bring it within an acceptable correction range. An alarm circuit which cooperates with the grind control circuit assures that once a grinding operation is begun it will have a predetermined minimum time duration. The alarm circuit also detects whether one of the shoulder grinders takes too long to engage the tire after the other shoulder grinder has made such engagement. The alarm circuit will stop the grinding operation if too long a period of time has elapsed and if there are other malfunctions of the grinders.
