Title: Biotransformation of fatty substrates
IPC: C12P7/64
Filed: 1990-08-31
Abstract: This invention relates to a process for enzymic oxidation of a fatty acid to produce an oxidation product in the presence of water and oxygen characterised in that the fatty acid, water and enzyme for the oxidation are substantially uniformly distributed throughout a porous bed of solid support material in the substantial absence of a continous liquid phase, oxygen is passed through the porous bed and the oxidation product is recovered from the porous bed. The invention is of particular value for production of methyl ketones from saturated fatty acids. Apparatus for carrying out the process is also novel and comprises a sealable vessel (1) that can contain a porous bed 4 of solid support material, a gas inlet (12) for supplying oxygenating gas to the reactor, a gas outlet (13), passage means (7) defining a plurality of upwardly extending passages that can open along their length into the bed and that communicate with the inlet (12) and that are preferably spaced 5 to 20cm (preferably 5 to 15cm) apart, and means for forcing oxygenating gas through the inlet and along and out from the passages and into the bed.

Patent EP-0493001-A3 (EP)
Title: A clock buffer with adjustable delay and fixed duty cycle output
IPC: H03L7/08
Filed: 1991-12-19
Abstract: A clock buffer circuit (10) for a computer system, and a computer system incorporating the same, are disclosed. The clock buffer circuit includes a differential input buffer (14) for receiving the input clock signal, with its output coupled to the input of a phase locked loop (PLL) (20). The switching level of the differential input buffer is adjustable (18), either by adjusting the DC bias applied to the input clock signal, or by adjusting the reference signal, which changes the point in the cycle of the input clock signal at which the differential buffer switches. The PLL synchronizes its output to an edge of the output of the differential buffer, but maintains the same duty cycle (e.g., 50%). Accordingly, the clock buffer circuit may have its delay adjusted, by modifying a voltage divider, applying a variable voltage, or programmably via a digital-to-analog converter, to match the delays of other clock buffer circuits in the computer system, reducing the clock skew in the system. A sine wave may be used as the input clock signal, so that harmonic noise is reduced in the system. <IMAGE>

Abstract: After a high-pressure container 1 is mounted to a
charging jig 2, on-off valves 82 and 83 are closed, and on-off
valves 81 and 84 are opened, so as to draw a vacuum in each
of a charging path7, the charging jig 2 and the high-pressure
container 1. After drawing the vacuum, the on-off valve 84
is closed, the on-off valve 83 is opened, for charging a
hydrogen from a combustible gas source 43 into the high-pressure
container 1 through a charging port 11. When a
pressure within the container reaches a predetermined pressure,
the on-off valve 81 and 83 are closed. In this manner, the
hydrogen is charged into the high-pressure container 1 in a
range except a flammable range. Then, the on-off valve 84 is
opened to draw a vacuum only in the charging path 7. After
drawing the vacuum, the on-off valve 84 is closed and the on-off
valve 82 is opened to charge an oxygen from an oxdizer gas source
5 into the high-pressure container 1. In this manner, the
oxygen is charged into the high-pressure container 1 in a range
except the flammable range. If a pressure within the
high-pressure container 1 reaches a predetermined pressure,
a sealing member operating mechanism 3 is operated so that the
charging port 11 of the high-pressure container 1 is sealed

Patent EP-0818738-A3 (EP)
Inventor: MOU ALEX ZHI-JIAN
IPC: G06F17/17
Filed: 1997-07-01
Abstract: Symmetry in a filter is used to reduce the complexity of an interpolator or a decimator and
to simplify derivation of resulting discrete samples. In particular, an inverse relationship between
weights applied to two samples is recognized and exploited. An inverse relationship is recognized
when a first weight is associated with a first of the samples and a second weight is associated with
a second of the samples and a weight which is equivalent to the first weight is associated with the
second sample and a weight which is equivalent to the second weight is associated with the first
sample. The inverse relationship is exploited by forming two composite weights of the first and
second weights and weighting composite sample signals with the composite weights. A first of
the composite weights has a value which is one-half of the sum of the values of the first and
second weights. A second of the composite weights has a value which is one-half of the
difference of the values of the first and second weights. The composite weights can be used
repeatedly for each subsequent interpolation or decimation and are therefore calculated only once
for processing many samples according to the same filter. The two composite samples have
values which are, respectively, (i) the sum of the values of the first and second samples and (ii) the
difference of the values of the first and second samples. The number of required adders is further
reduced in accordance with the present invention by using a single adder to produce two
intermediate signals corresponding to respective sums of two pairs of source samples. The adder
is used during one time interval to produce the first of the intermediate signals and during a
subsequent time interval to produce the second of the intermediate signals. The two intermediate
signals are combined in the production of a resulting sample by producing a signal corresponding
to the first intermediate signal, delaying for a time interval, producing a signal corresponding to
the second intermediate signal, and applying the signals corresponding to the intermediate signals
to an adder which produces a signal representing the sum of the values of the two signals.
