Patent EP-0341306-A1 (EP)
Inventor: NORLING BRIAN L
IPC: G01P15/10
Filed: 1988-10-10
Abstract: An accelerometer comprising a support (52) and 
a proof mass (40) mounted to the support by a flexure 
(50) or the like, such that the proof mass can rotate 
about a hinge axis (HA) perpendicular to sensitive axis 
(SA). An isolator (42) is also mounted to the support 
by an isolator suspension system (60, 62) that is rela­
tively compliant for isolator movement parallel to a 
transducer axis (TA) normal to the hinge axis, and rel­
atively noncompliant for isolator rotation about the 
hinge axis. Force transducers (80, 82) are connected 
between the isolator and the proof mass. The force 
transducers are parallel to the transducer axis, and po­
sitioned on opposite sides of the hinge axis from one 
another, such that rotation of the proof mass about the 
hinge axis puts one force transducer in tension and the 
other force transducer in compression. The isolator su­
spension system reduces the magnitude of common 
mode inputs, such as those caused by differential ther­
mal expansion of the crystals with respect to other ac­
celerometer components.

Title: Containers with tamper evident closures.
Inventor: CALVERT JOHN RICHARD
IPC: B65D45/32
Filed: 1989-03-15
Abstract: A tamper evident band (16) is provided around an area of cooperation between a container mouth (18) and a closure cap (11). Sloping faces (15) and (24) on the container and cap respectively allow the cap, surrounded by the strip (16) to be pushed on to the container, but shoulders (14) and (23) prevent subsequent removal of the cap without first removing the band (16). When the band (16) is removed, the cap can expand radially when pulled upwardly to release the engagement between the shoulders (14) and (23), and so allow removal of the cap. The cap and band (16) may be moulded together from a plastics material, with the band (16) depending from the edge of the cap and being attached thereto by a frangible portion (17, Fig. 1). At some point prior to, or during the assembly with the container, the frangible portion is broken and the band (16) moved to surround the cap as shown.

Abstract: Circuit for the regeneration of the clock signal within a message containing a preamble and random data. No assumptions on the message structure is required for the operation of such circuit, as this operates on the autocorrelation principle, which frees the datum format from the VCO which reconstructs the clock signal. 
     Such device finds its preferred application in a data transmission system and therefore belongs to the information and electrical communications theory field. 
     It is essentially formed by a phase correlator (1), a filter (2), an amplifying stage (3) and a VCO, where the correlator is in turn formed by a delay line (7), two multiplying elements (5) and a sampled delay element and may be implemented in a digital or analogue form.

Inventor: WIREMAN WALLACE H
IPC: B01D53/04
Filed: 1990-02-19
Abstract: An improved gas and odor adsorbing unit (1). The unit comprises a container (2) having a bed of particulate odor and gas adsorbing material therein constituting a molecular sieve. A tubular passage extends through the container and bed and is provided with a perforated peripheral wall (20) adjacent the bed. The bed is fully enclosed except at the perforated tube wall (20). Air containing moisture, gases and odors is directed through the tubular passage. The molecular sieve bed has an affinity for gases and odors and an affinity for moisture as well. By directing the air through the tubular passage, rather than directly through the bed itself, more of the gases and odors and less moisture will be adsorbed by the bed, increasing the working life of the bed. This effect may be further improved if the tubular passage is provided with diffuser material such as baffles, polyester, or fiberglass to slow down and disperse the air passing therethrough. The molecular sieve bed preferably contains indicator particles which change color when the bed needs to be changed. To this end, the container is preferably transparent allowing visual inspection of the bed. The unit can be either static or dynamic, depending upon whether air is directed through the tubular passage by the flue effect or by fan means.

Abstract: A method and compositions for reducing friction between relatively slideable components is described comprising applying to a slideably engaging surface of the slideable components a lubricating amount of at least one Newtonian, or non-Newtonian, metal overbased salt of a carboxylic acid wherein the metal is selected from the group consisting of lithium, calcium, sodium, barium, magnesium, and mixtures thereof, and the carboxylic acid comprises at least one linear unsaturated hydrocarbon group containing from about 8 to about 50 carbon atoms. The types of slideable components contemplated include flat bearings, rotating bearings, lead screws and nuts, gears, hydraulic systems, and pneumatic devices. The inventors have discovered that applying a metal overbased salt of the aforesaid carboxylic acids results in a remarkable reduction in static and dynamic coefficients of friction and provides anti-wear protection of an extreme pressure agent without requiring auxiliary friction-modifying agents or auxiliary extreme pressure agents.
