A process for preparing a cellular polymer containing perforated cell windows in the presence of a perforating agent being a substance that has a critical surface free energy of less than about 23 mj/m2 is disclosed. The cellular polymers obtained according to this invention have a fine cell structure and show enhanced dimensional and thermal insulation stability. The invention also relates to rig...

Apparatus for determining the position of a mobile vehicle relative to a fixed location marker device (10,20) which comprises a coil (22) energized to emit a magnetic field composed of lines of magnetic flux extending radially and arcuately from the ends of the coil's longitudinal axis (12). A sensor unit mounted on the mobile vehicle comprises four identical sensing coils (A,B,C,D,) each responsi...

The invention relates to a process for the production of substantially non-alcoholic beer by a continuous yeast treatment at a low temperature. In the process, wort which has been clarified and possibly treated by evaporating and/or with an absorbing agent is passed through a packed column reactor containing immobilized yeast at a temperature ranging between the freezing point of wort and +10 DEG ...

1. Dispositivo di sterzo regolato per mantenere in corsia autoveicoli in marcia.2.1. Nei noti dispositivi di regolazione della sterzatura, o si esegue una commutazione tra l'esercizio manuale ed automatico, il conducente non avendo alcuna possibilità di impegno diretto nell'esercizio automatico, oppure la regolazione stabilisce un momento di sterzatura, applicato in aggiunta a quello del conducent...

The invention relates to a process for producing a hard-metal or ceramic bar which has at least one helical internal hole (16) and a smooth outer surface. The plasticised extrusion compound is forced through a die (2) with a smooth bore (4). Arranged within the die (2) is a twisting device (8). This twisting device (8) imposes a twisting motion on the extrusion compound or, alternatively, a rotati...

In order to adjust or programme the control signal delivered by the receiver of a remote-control system to the object being controlled, the invention calls for an adjustment command (Y) to be transmitted to the receiver and to be processed by the receiver to adjust or programme its output unit at the interface with the object being controlled. Thus, instead of adjusting or programming th e output ...

A method of producing a liquor, comprising the steps of feeding yeast to be fixed into a fluidized bed reactor equipped with a liquid circulation pipe and a gas exhaust port, supplying a brewing raw material liquid to the reactor, extracting a part of a culture liquid from the top of the reactor and returning the culture liquid into the bottom of the reactor. By this method fermentation is conduct...

A waste compaction and liquid extraction system (10) and method are provided. The system includes a tank (12) for containing liquid and solids, and a tray (32) that seats on the tank. The tray includes a feeding system for moving bags (530, 540). A rotary disc impeller (64) is mounted in the tank for grinding. A stationary screw (34) is mounted to the outlet port of the tank. A cylindrical sieve (...

The invention relates to a safety ski binding, having a soleplate which is rotatable about a vertical journal on the baseplate and on which a heel restraint is mounted, provided with a sole holder which can be pivoted up against the force of a first spring acting on a releasable locking, on which soleplate a ski boot inserted into the binding rests, the soleplate being pressed into its central pos...

The support for the front of a ski-boot (2) sole on the ski (3) consists of a longitudinally-movable support-plate (6) and attachments for it. The attachments consists of a front (17) and back (18) crosswise ramp between which is positioned the movable support-plate (6). The gap between the front (17) and back (18) ramp is minimal in the vertical lengthwise plane of symmetry (P) of the support....
