Title: Process for separating particles of electrically non-conductive material, in particular plastics material and/or paper, from waste, and a device for carrying out the process
Inventor: FREI JOSEF
IPC: B03C7/00

Granted: 1992-08-04
Abstract: ABSTRACT   A process for separating particles of electrically non-conductive material, especially plastics material and/or paper, from waste, in which before separation the waste may be prepared by comminution, dehydration and/or loosening up, is to be further developed so that the particles of non-conductive material can be removed simply and economically.  This is achieved by subjecting the waste, as a heterogeneous stream of material of limited particle size, at a first station to a treatment which electrostatically charges the particles of non-conductive material and at a subsequent second station extracting the electrostatically charged particles, in the fluidized or suspended state of the stream of material, from the stream of material by means of at least one receiver of opposite electrostatic charge.

IPC: G02B6/44
Filed: 1988-03-01
Granted: 1991-12-17
Abstract: ABSTRACT         Disclosed is an apparatus for manufacturing cables comprising optical fibers and of the type comprising a core pro-vided on its outer surface with at least one groove in the form of an open helix which receives at least one optical fiber.  The apparatus comprises a plurality of bobbins carrying the optical fibers and which rotate about their own axes and which are mounted on a fixed frame.  A head to insert the optical fibers in the grooves of the core is provided with a through cavity for the passage of the core and with a plurality of extensions to be inserted in the core grooves and extending from the wall of the through cavity, the extensions each having a through hole for the passage of the optical fibers.  A rigid tubular body inter-posed between the coil-holding frame and the head permits the passage of the cable core and supports the optical fibers on its outer surface.  A mechanism is provided for the rectilinear advancement of the core and causing alternative rotational move-ment of the head.  The apparatus has a first and a second optical system for each optical fiber.  The optical systems each comprise at least one photoelectric cell system arranged transversely to the direction of advancement of the optical fiber.  The first system provides signals determining an increase in the speed of the mechanism paying off the optical fiber and the second optical system provides signals determining a decrease in the speed of the mechanism paying off the optical fiber.  An axial plane con-taining the catenary configuration of the optical fiber inter-sects the light received by the photoelectric cells.

Abstract: ABSTRACT OF THE DISCLOSURE            A skimmer for subgrade preparation with a skimming beam which can be towed over the subgrade, and which has a cambered portion for receiving sand, gravel or similar material during operation.  The cambered portion opens towards the unfinished subgrade.  During operation the skimming beam can be towed by means of chains, ropes or similar connecting means from a mobile appliance.          The invention is characterized in that the cambered portion is shaped as a skip-like space which is designed to receive excess sand or gravel that is pared off during operation.  The space is bounded by a lower wall, sidewalls and a rear wall.  An attachment is provided on the skimming beam for the purpose of attaching the beam to the mobile appliance in a manner such that the beam can be manipulated therefrom, so as to enable it to be emptied.  An advantage of the skimmer is the skip-shaped container, in which the sand that is pared off during a skimming operation can be accommodated, so that there is no need to remove it by hand in the course of the skimming operation as is the case with prior art devices.

Abstract: ABSTRACT          A vehicle having  a  boom assembly for applying herbicides, pesticides,  or fertilizers  in  fluid  form,  i.e.  as  liquid, powders  or  granules,  over  tracts  of  land,  has  opposite end-portions  of  the  boom  projecting  away  from  respective opposite sides of the vehicle.  Each end-portion is connected by a universal joint to a central frame which is fixed to the vehicle,  and  its  weight  is  supported  by  guys  which  are tensioned  by  a  spring  and  interconnect  the  two  boom end-portions.  A spring leaf skid is provided under each boom end-portion  and bears on  the  ground  only  if  the  vehicle rocks.  The guying is so arranged that rocking of the vehicle in one direction causes the slack from the boom end-portion whose skid bears on the ground to be fed to the other boom end-portion so that the spacing from the ground of the two boom end-portions remains acceptably constant despite rocking of the vehicle.

Abstract: HINGE FOR SLEEPER CAB DOORS                   ABSTRACT OF THE DISCLOSURE            A hinge for a sleeper cab compartment door that pivots between open and closed positions about a general-ly vertical hinge axis. The door frame has a jamb adapted to support a butt hinge and the door has a hinge stile spaced from the jamb when the door is closed so that the respective jamb and stile surfaces are separated by an elongated gap that is closed on the outer side by an elongated skirt portion extending laterally from the front panel of the door and adapted to swing inward into the gap when the door is pivoted to its open position. The jamb leaf of the hinge has a longitudinal bend divid-ing it into two flat flanges angularly disposed relative to one another, one of the flanges being secured to the jamb and the other forming a bearing for the hinge pin. The stile leaf also has a  longitudinal bend dividing it into two: flanges angularly disposed relative to one another, one of the flanges being secured to the stile and the other terminating in a bearing for the hinge pin that interfits with the bearing of the corresponding flange of the jamb leaf.  When the door is opened, the edge of the skirt engages the other flange of the jamb leaf to limit the outward swing of the door and thus, prevent the outer surface from engaging the outside edge of the door frame.

Filed: 1988-08-18
Granted: 1992-10-27
Abstract: APPARATUS FOR REDUCING STRESSES THAT INITIATE RE-STRIKE OF BREAKERS IN DISCONNECTING OF CAPACITOR BANKS   ABSTRACT OF THE INVENTION         Re-strike in the circuit breaker of a capacitive load applied across an AC voltage power supply is reduced or avoided by connecting across the capacitor bank a tuned discharge circuit.  The tuned discharge circuit includes a transformer with a primary connected in parallel with the capacitor  bank  and  a  secondary which  can be  shorted through a switch.   The leakage reactance of the trans-former is equated to the capacitive reactance of the capa-citor bank so that the tuned circuit discharges the capa-citor voltage  in phase with the  supply voltage.   The discharge takes place  through a number of cycles thus gradually increasing the voltage across the breaker gap.        The switch in the secondary preferably comprises an anti-parallel pair of thyristors fired by a circuit responsive to current zero in the capacitive circuit detected over a delay period to avoid firing at normal zero crossing cur-rent.

Abstract: ABSTRACT            Tungsten-titanium sputtering targets with  improved characteristics are made from high-purity tungsten powder and a second powder consisting of high-purity titanium hydride powder or high-purity titanium hydride powder and high-purity titanium powder.  The second powder contains at least 5%, preferably 25% to 100% by weight of titanium hydride powder.  A powder mixture having a binodal particle size distribution with respect to the tungsten and second powders is placed under a containment pressure in a die. The die is heated in a vacuum hot-press chamber to a temperature sufficient to dehydride the titanium hydride, and to remove gases and alkali metals.  The die is then heated to a second temperature in the range of 1350 to 1550°C while maintaining the containment pressure and vacuum.  A compaction force in the range of 2000 to 5000 psi is then applied to form a compact.  The compaction force and vacuum are subsequently released and the compact is cooled. The compact is easily machined to give a sputtering target having a density of at least 95%, preferably, at least 100% of theoretical density, a total gas content of less than 850 ppm, a carbon content of less than 100 ppm and low particulates upon sputtering.
