摘要:
A vacuum pump comprises pumping elements arranged in a pumping chamber. An electric motor drives the pumping element. A frequency inverter is provided for changing the rotational speed of the electric motor. The frequency inverter is arranged in a frequency inverter housing immediately connected to the pump housing. An air cooler and a liquid cooler are arranged in the frequency inverter housing to cool the frequency inverter.

Accurate “Mixing” of a sound signal has hitherto required a recording studio environment. Currently, both professional music producers facing budgetary limitations and amateur music makers without access to such meet a difficulty in producing music which has been correctly “Mixed” and “Auditioned”. We therefore propose a “Mixing” and “Mix Audition” tool, which can use standard headphones as the method of reproducing the direct sound, together with a DSP system that can be used with a computer based music production system to simulate specific listening experiences. The present invention therefore provides an audio auditioning device comprising a sound input, a sound output, a digital signal processor, and a library of stored digital signal processor effects, wherein the digital signal processor is adapted to apply a chosen effect from the library to a sound signal provided to the device via the sound input and deliver this to the output, and the library includes a plurality of digital signal processor effects representing the effect on a sound signal of reproduction in different environments. The digital signal processor applies the chosen effect in real time. The effects can include a home stereo, a home multi channel cinema, a large cinema, a concert hall, a car interior, and a radio receiver, or the like. The audio auditioning device can be combined with a computing device which includes a stored sound signal, mixing software adapted to adjust the mix of the stored sound signal, and a sound output connected to the sound input of the audio auditioning device.

Methods for detecting cancer that include hybridizing a set of chromosomal probes to a biological sample obtained from a patient, and identifying if aneusomic cells are present in a selected subset of cells obtained from the biological sample are described. A set of chromosomal probes and kits for detecting cancer that include sets of chromosomal probes, are also described.

A hip, ridge or rake shingle comprised of a plurality of panels sandwiched on each panel portion side of a layer of shingle material, such that each panel portion can be folded along a fold line, and wherein tabs are provided for each panel portion, adapted to be bent backwardly upon themselves, sandwiching thickening panels therebetween. The shingles can be laid up on a hip, ridge or rake of a roof, to yield desirable thickened features.
摘要:
A shingle is provided and its method of manufacture, in which granules are applied to an upper surface of a hardenable coating on a layer of shingle-making material, with granules of different pre-selected visual aesthetics provided in different tab areas, separated by mixtures of granules from adjacent tab areas forming intermediate areas, and in which the intermediate areas are removed to yield slots separating adjacent tabs, leaving visually sharp, precise starting and ending delineations for the tabs of a given aesthetic, that can be the same as or different than the aesthetic of an adjacent tab.
摘要:
Rotary switches, and in particular riser-style commutators, are detailed together with featured strips from which they are made. Segments formed from the strips may include anchor notches and slots for receiving reinforcing rings. The structure of the strip additionally permits electrical isolation of adjacent riser segments to occur through its coining rather than through slotting.

A system of nodes may communicate a signal between nodes in a manner that prevents looping the same signal through the same node. When a node receives a signal, it may evaluate whether the signal itself includes an identifier of the receiving node, indicating whether or not the receiving node has previously broadcast the signal. The receiving node may have an internal memory with a record of previously broadcast signals, against which it may compare a received signal to determine if the received signal is one that has been previously broadcast. If the signal has previously been broadcast, then the receiving node may discard the signal. If the signal has not previously been broadcast, then the receiving node may add its own unique identifier to the signal and rebroadcast the signal. The internal memory of the receiving node may also be updated to reflect the broadcast.
摘要:
A screw vacuum pump, in particular for compression against atmospheric pressure, comprises a pump housing defining a suction chamber. Two meshing screw rotors are arranged in the suction chamber. Further, an overpressure outlet provided, which comprises an overpressure opening in a side wall of the suction chamber. Further, an overpressure valve is arranged in the overpressure outlet. The width (b) of the overpressure opening in the longitudinal direction of the screw rotors is smaller than or equal to a tooth width (B) of the screw rotors.
摘要:
A fastener system including a threaded fastener having a slot formed in the fastener head. Facets are formed in the slot walls, each facet having an angle of less than ninety degrees with respect to the base of the slot such that the slot has a variable width and at least a portion of the width of the base is greater than the width of the opening of the slot. A driver bit includes a blade configured to be inserted into the slot of the fastener. At least a portion of the free end of the blade has an increased width such that the blade is locked within the slot of the fastener when torque is applied to the driver bit.
