Title: Separator
Inventor: MARRIOTT PAUL A
IPC: B03B5/00
Filed: 1990-10-02
Abstract: ABSTRACT      A gravity separator for the separation of heavier particles from lighter waste material comprises a stack of decks (4) mounted for resonant oscillatory motion within a supporting frame (1).  A motor (9) oscillates the decks at their resonant frequency while a distribution system (6) supplies a feed in the form of a slurry to the surface of the decks.  As shaking continues, the heavier particles within the slurry are gradually separated from the lighter particles. Optimal separation is provided by a control system which, if necessary, automatically changes the amplitude of oscillation and/or the timing of the stages as separation proceeds, for example in response to outputs of detectors which measure the frequency of oscillation and the power being consumed.

IPC: G10L25/78
Filed: 1991-04-08
Abstract: ABSTRACT OF THE DISCLOSURE      A speech detection apparatus capable of reliably detecting speech segments in audio signals regardless of the levels of the input audio signals and the background noises. In the apparatus, a parameter of input audio signals is calculated frame by frame, and then compared with a threshold in order to judge each input frame as one of a speech segment and a noise segment, while the parameters of the input frames which are judged as the noise segments are stored in the buffer and the threshold is updated according to the parameters stored in the buffer. The apparatus may utilize a transformed parameter obtained from the parameter, in which a difference between speech and noise is emphasized, and noise standard patterns constructed from the parameters of the input frames pre-estimated as noise segments.

Abstract: A rake head having an elongate hollow body with an aperture in one side of the body.  A cylindrical plug extends through the aperture and across the inside of the body where it is anchored to the rake head by a screw.  The rake handle is fitted over the plug and held in place with another screw fastening the head,  the handle and the plug together.   The rake  head  has  a  row of tines  spaced along the body and projecting from it orthogonally with respect to the handle.          The tines are each rhombic in profile, with long diagonals aligned  transversely  of  the  body  and  short  diagonals substantially  perpendicular  to  the  long  diagonal.    This produces a reduced drag compared with cylindrical or other rounded tines.  The rake head has an octagonal profile with a trailing face adjacent the tines oriented at an obtuse angle with respect to the tines.
