A container is disclosed for storing refrigerated liquids, in particular for liquefied gases, which comprises a steel reinforced concrete outer container and a steel inner container inserted into the outer container, where the steel inner container rests on an insulation and where an annular interspace is present between the outer circumference of the inner steel container and the inner circumfere...

A dry shaver has a shearing foil clamped to a holder detachably mounted on a shaver housing over a cutter. The holder is arranged to enable the shearing foil to be moved between an operating position wherein the shearing foil is wrapped around the cutter in a wrap angle exceeding 180 DEG and a second position wherein the wrap angle is less than 180 DEG to facilitate removal of the holder and she...

A novel reactor for enzymatic reactions comprises a flow cell which is constituted by two semi-blocks having a planar surface. The enzyme is immobilized on one of the semi-blocks while a thin channel is provided on the face of the other semi-block. The two semi-blocks are hermetically closed. The substrate solution follows a tangential motion and travels with a laminar flow. The reactor permits to...

Filter medium in the form of a stable body made of ceramic material and employed for filtering molten metals. The filter medium is made up of at least two effective filter layers such that a relatively thick layer of large pore diameter lies on a relatively thin layer of small pore diameter. This arrangement aims at attaining the maximum possible wetting of the interior of the filter medium.

PURPOSE:To prevent a driver or passenger from taking his seat under hazardous condition by installing a stopper slidably on the seat cushion and making thereby the seat back swingable in the forward tipped position. CONSTITUTION:A hook part 7' of a seat back locking device 7 is disengaged from the locking pin 8 to tip the seat back 5 forwards, and a seat locking device 14 is unlocked to rotate the...

PURPOSE:To attain quick coordinate input with a simple constitution, by reflecting an incident light given from a rotary mirror toward the tablet surface and reflecting the light to the back side of tablet after the scanning toward x and y directions. CONSTITUTION:The light from the rotary mirror 11 passes through the back side of a tablet board 10 and is made incident on reflecting mirrors 13, 14...

In a method of manufacturing a glazing panel comprising sheets which are joined together along the margin of the panel using heat-activatable bonding medium (e.g. solder) which is electrically conductive and/or in contact with electrically conductive material and which is activated in situ by induction heating, the induction heating is performed using an inductor 65 powered by an aperiodic generat...

The present invention relates to a method of manufacturing terra cotta pavings which may be used for ground surfacing, said pavings not being frost-susceptible, being porous and water-permeable, comprising the steps of: intimately mixing 100 parts by volume of clay with 80 to 160 parts by volume of dry, non-compressed sawdust, essentially formed of particles whose average diameter is included betw...

A system (10) for determining the level of a fluidised bed uses a minimum number of pressure sensors. A pressure sensor (12) is positioned at the base of the bed, another pressure sensor (14) is positioned at approximately 2.44 m (8 ft) above a distributor plate, and other pressure sensors (16, 18) are positioned at intermediate locations therebetween. The measurements from the sensors are selecti...
