Methods of applying an electrical conductor of conductive epoxy resin comprise applying the resin to a substrate, applying a resist over part of the conductors (14) leaving exposed contact pads (16), applying e.g. by printing polymer ink, temporary conductors (20) to the substrate (10) connected to the areas (16), immersing the substrate in an electroplating bath and passing an electric current th...

A surface coil arrangement for magnetic resonance data acquisition comprising a first coil designed to generate a circular magnetic field and a second coil designed to generate a linear magnetic field in quadrature to said circular magnetic field with said first and second coils positioned relative to one another to provide circular polarization.

An insert (l4) for a breast pump of the type comprising a milk reservoir, an essentially rigid suction bell (ll, 2l) having a flared open end, and a suction means for temporarily reducing an ambient pressure within said pump; the insert (l4) is formed of a soft and resilient polymer material that is inert against water at a temperature of at least about l00 DEG C and is a substantially monolithic ...

The present invention provides nuclear magnetic resonance apparatus for producing resonance information in the form of first and second spin echo signals, comprising: means for applying a static magnetic field to a subject being examined; means for applying a first radio frequency signal to said subject for inducing nuclear magnetic resonance information signals; means for applying a second rad...

A system for detecting the failure of a control system and its object includes a mathematical model of the control system and its object which continuously predicts the output of the object. An error signal is continuously calculated which is the difference between the model output and the actual output of the object. Error signals exceeding a predetermined minimum value or deadband are integrated...

A novel 1,3-dithiane of the formula wherein R1 is a di-substituted amino group; R2 and R3 are such that one of them is an electron-withdrawing group with the other being a hydrogen atom, a hydrocarbon group or heterocyclic group of the class consisting of thienyl, triazolyl, and pyridyl, which may optionally be substituted or that R2 and R3 taken together with the adjacent carbon atom fo...

A stable hydrocortisone-based composition comprises hydrocortisone solubilized in a mixture of an aliphatic alcohol, propyleneglycol and dimethyl coco-benzylammonium chloride.

The in-tank metering feed apportions additive as a function of a float-indicated tank level. A piston (11) controlled by the tank float (2) rides in a cylinder (5) to move additive volume as a function of the tank level. The feed volume of additive is in a constant ratio to the fuel replenishment volume. Assuming constant cylinder to tank (1) cross-section relationship, the ratio is pre-set at the...

Roll changers used previously are designed in such a way that rolls of web-type printing carrier, which have been prepared so that they are ready for gluing, are inserted into the respective replacement roll position and are completely unwound in each case when the roll change has taken place. The possibility of automatic application of an adhesive to the replacement roll and only partial unwindin...

An illumination device utilizes an electrical discharge through inert gas especially neon, argon, and mercury vapor or mixtures thereof, the electrical discharge being contained within two or more vitreous plates and confined within one or more channels within the vitreous plates. These channels, in combination with evacuation and gas filling means, provide one or more ionization chambers, the cha...

The tamper-proof device for closures of containers, in particular bottles, has a label (12) which, when it has been removed or damaged, makes opening recognisable. The closure parts (4, 6), which are to be moved apart for opening, are provided with flat depressions to accommodate the label (12). The depressions pass from one closure part into the other or others and jointly have the contour and si...

The bobsleigh training appliance takes up less room than an actual bobsleigh and can be erected anywhere. The appliance has running strips (6) for the bob-sleigh (1) athlete, simulating the starter tracks. The tobogganer practises run-up speeds, with a chronometer (12) measuring and indicating the run-up times. USE/ADVANTAGE - A high-intensity of training can be achieved with the bobsleigh trainin...

A breakstem blind rivet comprises a deformable tubular shell (11) of aluminium alloy having a bore (12) inside it. A stem (13) of low-carbon steel is a close fit within the bore, extending along the bore and having a head (14) adjacent the tail end (15) of the shell. The outside of the shell is formed with at least three zones (27, 28, 29) of modified strength spaced apart along its length, these ...

An improved method of initiating handoffs between sectors so as to reduce sectored voice channel interference is disclosed. The sectors that are adjacent and to the rear of the sector that is serving the mobile unit are scanned for signal quality. A handoff request message is sent to the cell controller if the signal quality detected by any of the scanned sectors is better than the signal quality ...

The invention relates to a seal for detection of the access to an object or a relative motion between a plurality of juxtaposed objects. According to the invention, the seal is comprised of an envelope (1) with dimensional recovery arranged to cover at least partially the object or objects (21, 22) and presenting, at least after dimensional recovery, weakening areas (4). Application particularly t...
