A self-rising dough-containing food product, particularly pizza, in which a non-yeast containing leavening system is combined with an uncooked dough in the presence of a moisture retention agent and dough conditioners to provide a frozen raw food product that may be cooked directly from the freezer in a microwave oven. The dough in the self-rising dough containing food product reaches full development in shorter mixing times at lower mixing speeds than conventional dough-containing products.

Apparatus for use in the bleeding of fluid systems, especially the hydraulic brake system of a motor vehicle, comprises fluid pumping equipment (1) for pumping fluid to a main fluid reservoir (8) of the fluid system via a supply conduit (24). The pumping equipment (1) includes a fluid container (6) and an air pump (2) serving to discharge fluid from the container (6) into the supply conduit (24). The pump (2) is driven through an electric circuit (C1.C2) including a fluid pressure control (14) and a fluid level control (15A) of the container (6). The delivery end of the supply conduit (24) passes through an opening (26) of the reservoir (8) which opening (26) is sealed by an elastomeric plug (18) laterally expandable by a compression device. The above apparatus considerably conveniences the bleeding of motor vehicle brake systems.
摘要:
A dewatering module adapted to be inserted between a rock drill bit and a drill string comprising an outer housing and having a first end remote from the drill bit and a second end adapted to lie immediately adjacent the drill bit; an air/water inlet at the first end of the module adapted to receive a high pressure composite air and water flow from within the drill string and to deliver said flow into a main chamber within the module; an inner tubular housing within the chamber defining a passage within the chamber from its first and inlet end adjacent the air/water inlet to its outlet and second end at the drill bit; the first and inlet end of the inner housing being shielded by a first baffle from the composite air water flow entering the chamber; the first baffle comprising a deflector overlying the first and inlet end of the inner housing and having a skirt being of larger diameter than the tubular inner housing inlet such that air entering the inner housing is forced to reverse direction and traverse an “S” shaped path to enter the inner housing before traveling therethrough to the drill bit; a second laterally extending separator baffle beneath the skirt of the first baffle located such that and being of a diameter adequate to prevent direct entry into the inlet of an air/water stream deflected from the base of the main chamber upwardly towards the inlet of the inner housing; holes in the sides of the outer housing remote from the air/water inlet and baffle and adjacent its second end to facilitate evacuation of water from the chamber and into the area where debris from the drilling operation is being exhausted.
摘要:
A speaker assembly aimable relative to a remote target. The speaker assembly comprising a sound generating device configured to project sound in a sound pattern about a sound axis. A speaker aiming device is coupled to the sound generating device for use in visually aiming the sound generating device relative to the remote target. The speaker aiming device having first and second aiming portions spaced apart from each other and positioned along an aiming axis in a fixed orientation relative to the sound axis. The first and second aiming portions being positioned to allow a user to visually see along the aiming axis past the first and second portions aiming device to the remote target.

摘要:
A speaker aiming system in accordance with one embodiment includes a speaker portion movable relative to a support portion, and a rotation adjustment device coupled to the speaker portion for rotation of the speaker portion relative to the support portion in first and second directions. The rotation adjustment device has first and second arcuate guides spaced apart from each other and rear rotation guide with first and second portions. The first arcuate guide and the first portion of the rear rotation guide are positioned along a common first arc that defines a first center of rotation. The second arcuate guide and the second portion of the rear rotation guide are positioned along a common second arc that defines a second center of rotation spaced apart from the first center of rotation.
摘要:
A method for learning that combines physical, verbal and visual interaction between a computer processing device (102) and a user. The method includes building an assessment matrix and generating an interactivity model for the user. The method also includes outputting one or more questions and associated answer choices to the user. The questions and answers can be outputted to a display device (202) of the computer processing device and/or to a speaker (202) of the computer processing device. The method further includes receiving an answer input from the user. Data associated with the answer input is processed by the computer processing device for building a user performance table. A response can be generated based on the answer input and in accordance with a verbal response mode (450). The response is then outputted to the display device and/or the speaker. Subsequently, the assessment matrix is modified to accommodate a level of expertise demonstrated by the user. A computer program product for learning that combines physical, verbal and visual interaction to assess and help raise the skill levels of various users is also provided.
