Title: Motor chain saw oscillation system - has vibration absorption device using elastic buffer between parts of vibration damper
IPC: F16F1/54
Filed: 1971-06-26
Abstract: The oscillation-generating assembly is held in a clasping frame which contains the fuel tank for the motor chain saw, suspended by means of vibration dampers. These are mounted in the main oscillation plane, and consist of two spaced part elements, and are shear loaded by vibrations occurring in this plane. One of these vibration dampers(44), at least, inserted between the top of the motor assembly and the clamp assembly, has an independent elastic buffer(108) inserted between the part elements. This is compression-loaded lengthways by excessive oscillations in the blade plane, but at normal oscillation amplitudes it is ineffective. The buffer may be conical at one end, with an axial blind hole in it. This permits rapid small-amplitude oscillations to be well absorbed, but stronger forces to be intercepted without excessive stress on the attenuator elements.

Patent JP-H0629205-B2 (JP)
IPC: C07C45/51
Filed: 1985-01-31
Abstract: The preparation of 1,4-butandial (succindialdehyde) is obtained using acrolein. The acrolein is first converted with an alkanol into 3,3-dialkoxy-1-propene and this is then hydroformylated in the presence of hydridotristriphenylphosphine-rhodiumcarbonyl mixed with triphenylphosphine or triphenylphosphite as the catalyst. The thereby obtained 4,4-dialkoxy-butanal is removed from the hydroformylation product by means of distillation and is then hydrolyzed to 1,4-butandial.
Patent JP-3364505-B2 (JP)
IPC: B65G47/52
Filed: 1993-02-19
Granted: 2003-01-08
Abstract: The present invention provides an apparatus for receiving, in an infeed section (10), a stream of distributed articles (100), such as food items and the like, deposited in rows of like position. A slide mechanism (11) is used to retard the motion of the items (100) as they drop off the infeed section (10). In particular, the slide mechanism (11) is alternately moveable between a slide position and a flip position. In the slide position, the item drops off the edge of the belt (10) and slides across the primary slide surface (11A) and onto a second slide mechanism (12) having a secondary slide surface (12A) that is positioned to be in substantially the same plane as the primary slide surface (11A). The slide mechanism (11) is moved into the flip position for every other row of items (100). The items (100) to be flipped come off the conveyor belt (10) and come into contact with an abutting surface (11B). This surface (11B) changes the direction of the item (100) as it moves towards the transport mechanism (20) in conjunction with a reverse slide surface (12B) of the second slide mechanism (12). The item slides down the reverse slide surface (12B) on its top surface, thus flipping over at least 180 DEG  from its orientation on the infeed conveyor belt (10). As a result a plurality of rows can be conveyed by the transport mechanism (20) to the filling and capping stations of an automatic sandwich making system, wherein alternate rows of food items (100) are oriented with their bottom surfaces facing upwards from the surface of the transport mechanism. <IMAGE>

Abstract: A method for decoding and synthesizing a synthetic digital speech signal from digital bits of the type produced by dividing a speech signal into frames and encoding the speech signal by an MBE based encoder. The method includes the steps of decoding the bits to provide spectral envelope and voicing information for each of the frames, processing the spectral envelope information to determine regenerated spectral phase information for each of the frames based on local envelope smoothness determining from the voicing information whether frequency bands for a particular frame are voiced or unvoiced. The method further includes synthesizing speech components for voiced frequency bands using the regenerated spectral phase information, synthesizing a speech component representing the speech signal in at least one unvoiced frequency band, and synthesizing the speech signal by combining the synthesized speech components for voiced and unvoiced frequency bands.

Patent JP-S6323806-B2 (JP)
IPC: B01D3/42
Filed: 1980-04-18
Abstract: A process and apparatus are provided controlling the heat input of an extractive distillation column. The bottom of the column is heated with a major stream of thermal energy which is either slowly varying in time or controlled by the amount of starting material mixture and with a minor stream of thermal energy which is controlled by sensing the thermodynamic state in the upper half of the column during the process. The major stream can provide about 90 percent and the minor stream about 10 percent of the heat fed to the column. The minor stream can be controlled by the temperature at one point in the upper half of the column, by the temperature difference at two points in the upper half of the column or by gas chromatographic analysis of the extract material concentration near the top of the column. The process allows one to keep a low concentration of the extract material in the raffinate.

Granted: 2001-04-03
Abstract: A floating point processor for performing arithmetic operations on floating point numbers includes a first arithmetic operation unit configured to operate on normalized numbers and a second arithmetic operation unit which includes a denormalizer for denormalizing normalized numbers and a normalizer for normalizing denormalized numbers. Each arithmetic operation unit has first and second inputs for receiving first and second operands, respectively, and an output for transmitting a result of the arithmetic operation. When an denormalized operand is presented as an input to the arithmetic operation unit configured to operate on normalized numbers, the denormalized input operand is redirected through the second arithmetic unit for normalization of the denormalized operand. The first arithmetic operation unit then performs its arithmetic operation using the normalized input operands. The result of the arithmetic operation is then analysed to determine whether it has a zero or negative exponent. If the result has a zero or negative exponent, the result is directed through the second arithmetic unit a second time so that the result is denormalized. The denormalized result is then output.

The method comprises the step of projecting the predefined surface area to a plane perpendicular to a line of sight between a predefined viewpoint and the print carrier, placing the advertisement information within boundaries of the projected predefined surface area and generating the advertisement print by graphically transforming the projected predefined surface area together with the advertisement information to an area similar to the predefined surface area of the substantially plane print carrier. The invention further relates to an advertisement print being printed on a substantially plane print carrier. The print is optimised to be placed on a surface of an inclined plane having a first inclination, and the print comprises a first element being a perspective projection of a first three-dimensional element to the inclined plane. The projection is optimised to a predefined viewpoint, where a supporting surface of the three-dimensional element is parallel to a supporting plane having a second inclination being different from the first inclination. <IMAGE>
