Patent NO-178884-C (NO)
Inventor: MOTT JOHN R
IPC: C04B14/42
Filed: 1990-04-30
Abstract: A ladle is used in the manufacture of metals and for receiving molten metal for further chemical processing or for transportation. The ladle comprises a glass-cement outer shell (18), refractory linings (20,22) and trunnions (30). The ladle is transparent to a wide range of electromagnetic radiation wavelengths which allows the metal to be heated or stirred by induction without heating the ladle itself. As the ladle is made of glass fibre and an inorganic cement, strength is provided along with high temperature resistance. The ladle is manufactured by winding glass fibre around a mandrel, and incorporating an inorganic cement. The cement may be coated on the fibre as an aqueous slurry, and the product allowed to air cure after winding. Alternatively, the cement may be adhered to the fibre by electrostatic attraction. After winding is complete, additional cement may be added and the product placed in an autoclave supplied with steam whereby the cement takes up water; it is then allowed to cure. After curing, the moulding is preferably sawn in half to form two inductively transparent ladles.

Abstract: A tobacco product for producing a home-made cigarette, consisting of one or more tobacco portion(s) (47) comprising in each case at least two partial quantities (48 or 50) and being held together by inner and/or outer fixing means (49), each partial quantity (48 or 50) containing approximately the quantity of tobacco required for one cigarette, and the outer surface of the tobacco portion (47) and/or partial quantities (50) being permeable to air in such a way that it is impossible as such to draw through it and it is thus unsmokable. The tobacco portion (47) is formed either by two or more partial quantities (50) of rod-like shape in each case and connected, in particular bonded, to one another to form a rod belt (51), or by a flat oval tobacco unit comprising two or more partial quantities (48). The tobacco portion (47) is held together in each case in such a way that, when one partial quantity (48 or 50) is separated, this and the partial quantity immediately adjoining it are inevitably destroyed or broken up whilst removing the inner holding-together thereof. A stuffing apparatus is provided, in adaptation to the abovementioned tobacco, with a magazine (52) and a separating knife (1) for separating the individual partial quantities (48 or 50). <IMAGE>

Title: Full duplex lightwave communication system
Inventor: LINKE RICHARD A
IPC: H04B10/61
Filed: 1989-12-20
Granted: 1993-06-29
Abstract: FULL DUPLEX LIGHTWAVE COMMUNICATION SYSTEM Abstract Full duplex operation is achieved in a lightwave communication system by employing terminals having a distributed Bragg reflector (DBR) laser having separate electrically controllable Bragg reflector and gain sections. While operating as the basic heterodyne reception element, the DBR laser simultaneously generates lightwave signals for transmission to other terminals. External circuits process the electrical (intermediate frequency) signals from the simultaneously modulated and signal mixing laser to extract received information. In one embodiment, full duplex operation is described for an FSK lightwave communication system.

Abstract: A  method  is  described  for  balancing  and  then retaining  a rotatable unit  in a dynamically balanced condition.  In each end of the unit, there is an annular channel concentric with the rotational axis encircled by a flexible rim.  A plurality of balls of substantially identical  size  and  weight  are  inserted  in  an  outer portion of each channel in which the balls are freely movable.   While the unit is rotated at a speed above resonance,  a balancing instrument is used to determine the mass magnitude and angle necessary to dynamically balance the unit.  Then the balls are circumferentially relocated by vector balancing to provide mass at points equivalent  to  the  determined  mass  and  angle.   The relocated  balls  are  then  forced  axially  past  an interference  ridge  and  into  an  inner portion of  the respective channel in which the rim is flexed and the balls are held against movement.
