Title: Method and apparatus for processing log for sawmill including end dogging carriage which rotationally repositions log to cutting position determined by computer after non-rotational scanning
Inventor: MCGEE ARTHUR L
IPC: B27B1/00
Filed: 1994-10-28
Abstract: A log processing method and apparatus are described in which the log is moved laterally through a light scanner by a pair of charger arms to determine the configuration of the log and the best cutting pattern solution for such log by a computer from the scan data.      The log is skewed by adjusting the length and angular position of the charger arms to align the central axis of the log with the center of the cutting pattern solution. Then the log is swing by pivoting the charger arms into a transfer position where the log is transferred to an end dogging log carriage. After transfer, the log is rotationally repositioned into the desired cutting position by rotating it about a selected chuck of a plurality of chucks on one end dog with a driven dog blade on the other end dog which is aligned with the centerline of the cutting solution. After repositioning the log is clamped against further rotation by extending additional end dog chucks into engagement with the log. Then the clamped log is conveyed on the carriage through the cutting devices.      One of the cutting devices is a bottom chipping head which is vertically adjusted in height by the computer during cutting to produce a curved or straight bottom surface on the log.

Title: Method for manufacture of colored particles and suede-type paint constituents using the colored particles obtained by this method
Inventor: NISHIMURA YOSHIHIKO
IPC: C09D7/12

Abstract: To produce colored particles with a 10-200 µm average grain size simply, efficiently, and in high yields, in order to obtain suede-type paint constituents with excellent decorative features capable of producing finely detailed, marble-like, multi-color patterns. Water-insoluble particles and a polyvalent carboxylic acid resin with an acid value (solid-based) of about 20-120, either water-soluble or water-diffusing are mixed in water; and after primary coated particles are formed on the surfaces of the water-insoluble particles on which the polyvalent carboxylic acid resin is adsorbed, a dispersion-stabilized emulsion resin containing a colored pigment is mixed in the dispersion liquid; and a metal salt is added to this mixture so that colored particles with an average particle size of about 10-200 µm with a surface colored coating are obtained. The water-insoluble particles can be either synthetic resin particles or inorganic particles.

IPC: B27C7/06
Filed: 1995-01-13
Abstract: A method of controlling the clearance angle of a veneer lathe knife in a veneer lathe having a knife holder beam rotatably mounted on a knife carrier.   The beam's vibration frequency is continuously measured and compared with a stored representation of a vibration frequency range (about 50-200 Hz.) characteristic of disruption of the veneer peeling operation.  If the comparison reveals that the measured vibration frequency is within the characteristic disruptive range, the beam is rotatably adjusted until the comparison reveals that the measured vibration frequency no longer lies within the disruptive range.  Usually, the adjustment accelerates lowering of the beam in order to make the knife clearance angle less positive.

Title: Efficient digital quadrature demodulator
Inventor: INKOL ROBERT J
IPC: H03D3/00
Filed: 1995-05-29
Abstract: A digital quadrature demodulator for an intermediate frequency (IF) input signal with an analog-to-digital (A/D) converter having a sampling frequency fs and an input to which the IF input signal is applied where the IF input signal has a bandwith B<fs/4 centered about a frequency of fs/4.  The demodulator includes an arrangement to direct even numbered output signals from the A/D converter to an inphase channel and odd numbered output signals from the A/D converter to a quadrature channel where each channel contains a highpass filter and the demodulator includes circuits to decimate by 4 signals of the channels to generate, together with the filters, a quadrature output signal Q(nT) at an output of the quadrature channel and an inphase output signal I(nT) at an output of the inphase channel.  The quadrature highpass filter in the quadrature channel has an optimized transform architecture in which the filter coefficients hk correspond to those of a lowpass prototype filter with N=2k+1 coefficients after multiplication by sin(k.pi./2) where k identifies a particular stage of the filter.  The inphase highpass filter in the inphase channel has an optimized transform architecture in which the filter coefficients hk correspond to those of a lowpass prototype filter after multiplication by cos(k.pi./2).  Employing optimized filter architectures and simplified filter coefficients obtained with a new design procedure provides a practical quadrature demodulator design which can be economically implemented in hardware.

Title: Mechanical link arms
Inventor: SMITH JOHN EDWARD
IPC: F16H51/00
Filed: 1996-01-05
Abstract: A mechanical link arm for connecting together two rotary windscreen wiper shafts comprises a hollow tube of plastics material integrally formed by gas injection moulding with a socket connector at each end. Each socket connector closes off the end of the tube and serves for connection to a complementary ball connector on an associated one of the windscreen wiper shafts. Such a link arm is produced in one piece in a single fabrication step, and is therefore capable of being manufactured at significantly less cost than a conventional link arm. Furthermore the link arm is fabricated from a suitable plastics material so as to be both strong and light, and in addition so as to permit some flexing of the arm in the event of a mechanical overload so that such a mechanical overload will be less likely to cause burning out of the wiper motor.

Title: Preparation of fruits or vegetable pieces with homogeneous concentrations of ingredients and controlled textures and water activity
Inventor: HUYGHUES-DESPOINTES ALEXIS
IPC: A23L2/02
Filed: 1996-01-23
Abstract: In the field of dried fruits or dried vegetables, pre-drying treatments aim at improving the preservation, appearance, texture and sweetness of the dehydrated fruit while retaining the natural characteristics (flavours/colours) of the fruit.  In the present process, the cellular structure of fruits or vegetables tissues is disrupted by a thermal process and the natural soluble content of the disrupted tissues is partially and completely replaced by selected ingredients contained in a infusion medium.  The infused product is then partially dehydrated to an appropriate water activity.  Thus, the objective of the process is to substantially degrade the natural characteristics of fruit or vegetable tissues and use the disrupted tissue as a template for ingredients.  The key advantage of this process is to rapidly obtain a homogeneous distribution of ingredients within the porous disrupted tissues, allowing for the preparation of a spectrum of products with exotic colours, textures, and organoleptic properties.  The treated product pieces may be packaged in their original form or as a shaped mash of smaller pieces.
