Abstract: An apparatus for dispensing measured quantities of viscous material from a pressurized supply source including a measuring cylinder having a spring loaded piston therein and a rotary valve for alternately communicating the measuring cylinder with the supply source and with a discharge outlet. The rotary valve member has axially spaced O-ring seals to inhibit leakage from the ends of the valve member and an inlet seal for sealing against leakage from the pressurized inlet passage in a direction circumferentially of the rotary valve member.

Abstract: A bottle formed of a flexible plastics material such as biaxially oriented polyethylene terephthalate having a convex, generally rounded bottom incapable of supporting the bottle in a stable, upright position, and a flexible snap-on supporting cup applied to the bottom of the bottle. The base of the cup has a support surface for supporting the bottle in a stable, upright position.

Abstract: The invention includes the process of shaping a workpiece and for producing a surface contour complementary to the surface contour of a model. The process comprises the steps of applying a masking material to at least a portion of the surface of the workpiece to be shaped, the masking material being adapted to protect the surface from the effects of etchant. A template is then pressed against the surface, the template having a surface contour comprising a negative image of the surface contour to be formed in the workpiece, the template surface being comprised of material adapted to remove the masking material when the template is pressed against the surface and removed from the surface. The template is then withdrawn from the surface to remove masking material from those portions of the surface contacted by the template surface. Etchant is then applied to the surface not covered by the masking material.

Abstract: The improved automatic ripper reset mechanism of the present invention includes a punch fixedly disposed on the distal free end of a ripper blade head for downward arcuate motion in response to the ripper blade striking an obstruction, a die having a matching contour surface, an incrementally fed shear bar disposed opposite the punch for fixed engagement between the punch and the die when the reset apparatus is in ripping functional position, and to be sheared off when the reset mechanism is sprung, a reset mechanism frame supporting a spring loaded push block means for incrementally advancing the shear bar, brake means for preventing expulsion of the shear bar from the frame by the push block means when the reset mechanism is in sprung position, and torque storage means for receiving torque during the springing of the reset mechanism by means of striking an obstruction and for retransmitting the stored torque to reset the mechanism.

Abstract: A toilet has first and second hinges equidistantly spaced on opposite sides of a medial plane of the toilet with each hinge including a vertical hinge post having a horizontal pivot hole receiving a tubular pivot sleeve extending unitarily from a cover hinge body member with a pivot shaft of a seat hinge extending into the pivot sleeve for pivotal movement. The seat hinge and cover hinge each have outwardly extending spikes inserted in mounting bores in the seat and cover with the spikes having protrusions for retention in the mounting bores and being oriented at an acute angle to and flaring outwardly in reverse manner with respect to the medial plane with the post and hinge components being formed of fiberglass reinforced polypropylene.

Abstract: There is provided a method for tenderizing cut portions of meat, wherein the portions are slit by passing the portions into a plurality of rotating slitting blades having a plurality of discrete cutting surfaces on each slitting blade along the periphery thereof. A series of closely spaced first cut slits are produced from at least one surface into the said portions. The portions are then sprayed with a tenderizer solution containing a tenderizing phosphate, and the solution penetrates into and is retained in the said first slits. Further slitting of the portions is achieved by passing the portions into a further assembly of the rotating slitting blades and a series of closely spaced further cut slits are placed on the portions. The further slits are close to or in part overlap the first slits and the solution penetrates from or flows from the first slits into the said further slits during the further slitting and subsequent thereto. Immediately thereafter the portions are packaged and fast frozen.

Abstract: A carrying case which has a telescoping wall structure for varying the carrying capacity of the case. The case has an articulated wall construction and includes a bottom section which is adapted to fit snugly for retention within the lower end of the top section without the use of fastener elements. The case is integrally formed with the top and bottom sections being interconnected by a flexible coupling panel.

Abstract: A double nozzle injector system includes a manifold block with an internal conical sealing surface which receives an external conical sealing surface of a spindle coupling connected to an extruder for receiving molten plastic into an axial passageway terminating at a main outflow passageway extending transversely through the coupling. An annular flushing groove encircles the coupling with a plurality of angularly spaced radial flush passageways of small diameter extending between the annular flush groove and the interior of the coupling at the main outflow passageway. Runners in the manifold block are provided with plugs having spherical surfaces for directing flow to a pair of nozzle members attached to the manifold block. Upper and lower portions of the manifold block are controlled by separate heaters and thermostats.

Abstract: Dough compositions which are leavened and flavored by certain yeasts are provided, along with a process for production thereof. The particular yeasts are Candida lusitaniae and Saccharomyces delbrueckii. The yeasts do not effectively use sucrose as the primary energy source and the compositions will contain another sugar, e.g. dextrose.

Abstract: A key loop for releasably supporting keys on the key head of a key case. The loop is of integral construction and formed of spring metal rod stock and includes an enlarged head for connecting the loop to the key head at the upper end of a shank portion which extends downwardly from the head. From the lower end of the shank, the key loop is reversably curved outwardly and upwardly with its free end terminating adjacent the inner surface of the shank at a substantial distance below the head. The free end of the key loop includes a retainer portion which extends inwardly and at least partially toward the lower end of the loop. The upper surface of said retainer portion and opposed portion of the shank provide an access opening for the apertured head of a key. The inner surface of said retainer portion serves to prevent inadvertent removal of a key from the loop.

Abstract: A method and apparatus for controlling operation of a semi-frozen product dispensing machine. The control system includes a viscosity sensing mechanism for sensing the viscosity of the product in the freezing chamber and for shutting off flow of refrigerant to the freezing chamber evaporator when the product reaches the desired viscosity. The control system also includes a refrigerant pressure sensing mechanism for sensing the pressure on the refrigerant in the freezing chamber evaporator when the supply of refrigerant is shut off and for restarting the refrigerating mechanism when the refrigerant pressure in the evaporator rises to a preselected value. The control system also includes circuitry for restarting the refrigerating mechanism when the dispensing valve is opened.

Abstract: A puffable food composition is provided by extruding a mixture of ground animal parts and starch whereby the mixture is at least partially gelatinized during extrusion into a shape-sustaining form. The form is puffed either at the die of the extruder, or in subsequent hot oil frying, or both. With added flavoring, the puffed composition has the taste, texture and mouth feel of fried pork skins. The process accommodates a wide variety of animal parts without the necessity of substantial changes in the process parameters.

Abstract: A touch dimmer switch incorporating an integrated circuit for controlling a thyristor dimming circuit, has a touch control connected in a high impedance, unidirectionally conducting circuit, and a filter circuit for filtering out ambient electrical noise. The touch control is isolated from the AC power source so that the polarity of connection to the power source is not critical.
