Title: Frequency synthesizer
IPC: H03B23/00
Filed: 1988-11-24
Abstract: A frequency synthesizer is provided in which the output is a 
truly continuous sweep of frequency, not a staircase of spot 
frequencies. A programmable frequency divider PD is connected to 
the output of a voltage-controlled oscillator (VCO) to divide the 
VCO output by a variable integer N. At each VCO output cycle, 
the integer N is incremented (or decremented). The output of a 
phase comparator PC, which compares the divider output with a 
fixed reference frequency, is connected via an integrator (10) to 
the VCO frequency control input (2). A constant phase error 
produces a ramp rise of VCO frequency.

Abstract: A rotary valve has a valve rotor (10) with an angular discontinuity (17), the valve rotor (10) being mounted for rotation relative to a port (15), so that as it rotates the rotor (10) will open and close the port (15); a drive train (20,21) is provided to rotate the rotor (10), said train (20,21) being arranged to reduce the speed of the rotor (10) so that it is stationary or near stationary when the port (15) is closed; the port (15) is surrounded by a seating area and the valve rotor (10) is arranged to move into engagement with the seating area and close the port (15) as the speed of the rotor (10) is reduced and move away from the seating area as the speed of the rotor (10) increases.
Patent EP-0295965-A3 (EP)
IPC: C12Q1/6825
Filed: 1988-06-20
Abstract: A method for detecting a first member of a 
specific binding pair in a sample, the first member 
being capable of forming a complex with a second member 
of the specific binding pair, includes immobilizing the 
second member on a surface of a piezo-electric crystal 
oscillator, determining a first vibrational frequency 
of the oscillator on which the second member has been 
immobilized, contacting the surface of the oscillator 
on which the second member has been immobilized with 
the sample under conditions permitting formation of the 
complex, and with a mass increasing particle under 
conditions permitting binding of the particle with the 
first member, mass coupling the bound particle with the 
oscillator, and determining a second vibrational 
frequency of the oscillator with which the particle has 
been mass coupled, the difference between the first 
vibrational frequency and the second vibrational 
frequency providing a measure of the quantity of the 
first member in the sample. In an alternative method a 
particle binding member is used, having two binding 
regions capable of binding to the first member and the 
particle, respectively.  
     Because the mass of each particle is relatively 
greater than that of the member, the mass coupling on 
the surface effectively amplifies the mass increase 
owing to the specific complexing.

Title: Epoxide crosslinkable latices
IPC: C08L13/02
Filed: 1989-02-10
Abstract: It is known to crosslink polymers containing 
carboxylic acid groups using reactive resins or agents. 
Usually such systems contain or generate formaldehyde. It 
is now proposed to crosslink latices of low gel polymers 
containing carboxylic acid groups with lower alkyl esters 
of non terminal expoxides of long chain unsaturated fats or 
oils. Such epoxide esters have a low solubility in water 
and thus a good pot life yet react when heated at 
temperatures of less than 150°C in less than 30 minutes.

Title: Circuitry for the synchronisation of an asynchronous digital signal with a system clock
IPC: H04L7/033
Filed: 1989-08-10
Abstract: A synchronous output pulse of defined length is to be provided for an asynchronous digital signal of arbitrary length, maintaining high noise immunity with respect to metastable states. The asynchronous digital signal (IN) controls an alerting flip-flop (KO) which is connected to two series-connected synchronising flip-flops (K1, K2) which are controlled by clocks (CK1, CK2) which are phase-shifted with respect to one another in such a manner that a noise-free synchronous output pulse (OUT) of defined length is emitted within a predetermined time window. A special field of application is the synchronous transfer of asynchronously occurring data signals in processing units. <IMAGE>

Title: Method & apparatus for reducing power consumption in a radio telecommunication apparatus
IPC: H04B1/40
Filed: 1989-06-13
Abstract: A radio telecommunication apparatus is used in a radio tele­
communication system wherein one or more base stations broadcast 
radio signals over a plurality of radio channels. The apparatus selects 
at least a radio channel out of the plurality of radio channels and 
detects the availability of the selected radio channel. In response to 
the unavailability of the selected radio channel, the apparatus is 
intermittently powered so as to detect the availability of the selected 
radio channel while conserving battery power consumption. Even if 
the availability of the selected radio channel is detected, only recep­
tion and transmission sections are intermittently powered so that the 
presence of information signals to be transmitted is detected.

or unlocked to permit pivoting of boot parts about the living hinge. 
The boot also includes front and rear cuffs (20,22), and a releasable 
strap (28) securing the two cuffs together which, under predetermined 
rearwardly-directed load conditions, separates the two cuffs and permits 
free movement of the rear cuff. The resistance of the ski boot to 
forward and rear lean is controlled by a pair of oppositely directed 
springs (54,56) secured to the front cuff.

Title: A spreader bar apparatus
IPC: B65H35/02
Filed: 1989-10-12
Abstract: A spreader bar apparatus (10A) is disclosed for 
separating slit portions (30-34) of a web (WA). The 
apparatus includes a first spreader bar (12A) which 
extends in a cross-machine direction (CD) relative to 
the web. The first spreader bar (12A) is bowed relative 
to the slit portions (30-34) such that the slit portions 
are separated axially relative to each other when the 
slit portions (30-34) are guided around the first 
spreader bar (12A). A second spreader bar (14A) is 
disposed downstream relative to the first bar (12A) and 
extends in a cross-machine direction (CD) relative to 
the web (WA) for guiding the separated slit portions 
(40-44). The second bar (14A) is bowed relative to the 
separated slit portions (40-44) such that each of the 
slit portions (50-54) disposed downstream relative to 
the second bar (14A) is disposed parallel to each other. 
A first and a second porous layer are connected to the 
first and second bars (12A, 14A) respectively such that 
when the bars are connected to a source of pressurized 
air, air flows through the bars (12A, 14A) and the 
porous layers towards the slit portions(30-34, 40-44) 
for generating respectively a first and second air 
cushion. The cushions reduce the frictional resistance 
between the moving slit portions (30-34, 40-44) and the 
bars (12A, 14A). Additionally, the air cushions reduce 
the noise level caused by movement of the slit portions 
when the slit portions move relative to and are guided 
by the spreader bars (12A, 14A).
