Abstract: A hinge, in particular for furniture doors, of the type in which a wing is designed to be fitted to a base secured to the piece of furniture, comprises an intermediate  element for connecting the wing to the base having a substantially U-shaped transversal configuration to determine two  rigid sides which laterally embrace the base.          The intermediate element is provided with fastening  means for securing  it  to  the  wing,  and  unfastenable  means connecting it to  the base  comprising members  yieldingly fitted onto the  intermediate  element  in  two  portions spaced apart from each other in the longitudinal direction of the wing. Said yielding members are elastically  biased to  move  into  a  position  in  which  they  engage  with complementary housings in the base in order to couple  the intermediate  element  to  the  latter,  the  movement  of approach between the  base and the  wing for the  coupling being amply indeterminate.          The yielding members  fitted in at  least one  of the  two positions longitudinally spaced apart from each other are, moreover, provided with a portion which can be gripped  in order to force the yielding member  to disengage from  the housing in the base.          Furthermore, the base comprises  a first portion  provided from above with said complementary housings and from below with a slot  shaped to  receive a  second portion  screwed onto said first  portion and provided  with through  holes for  screws  in  order  to  secure  it  to  the  piece  of furniture. The slot being shaped to enable movement for  transversal adjustment of the position of the hinge.

Title: Union for fluid conduits, in particular for high purity gas
Inventor: SABATIER ANDRE
IPC: F16L23/04
Filed: 1990-04-11
Granted: 1999-06-01
Abstract: Each end fitting of the union has an end for fixing the fluid line, and a coaxial metallic body terminating in an annular radial polished section where the internal bore of the union issues.  A washer made of a deformable synthetic material is pressed on this metallic body and has a flat annular radial face which, together with the polished section, forms the free face for connecting the end fitting. A cylindrical metallic ring accommodates internally with a contact fit the two washers and a portion of the two metallic bodies, so that the two free connecting faces come to be opposite each other.  Two clamping half-shells grip the two end fittings to ensure the connection of the fluid lines.

Title: Radio telephone suitable for portable and vehicle-mounted use
Inventor: UEDA HIDEKI
IPC: H04W4/00
Filed: 1990-04-19
Granted: 1995-05-30
Abstract: A portable radio telephone comprises a receiver section including at least an RF amplifier and a first frequency mixer.  The telephone also comprises a battery which supplies a first voltage to the receiver section when the telephone is in portable use.  When the telephone is mounted on a vehicle, a vehicle battery applies a second voltage which is higher than the first voltage, to the RF amplifier and to the frequency mixer.  By this higher voltage supply, the intermodulation characteristic and reception sensitivity of the receiver section can be improved in the vehicle-mounted use.  On the other hand, battery saving can be achieved by the lower voltage supply in the portable use.

Granted: 1997-01-28
Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate.  Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer having water-cooled metal walls.  Some of the waste fines are melted to form a molten slag-like material that is removed from the apparatus and cooled to form non-hazardous aggregate.  The portion of the material in the oxidizer that is not melted, is cooled, neutralized and subjected to a solid gas separation.  The solid is reintroduced to the oxidizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate.

Granted: 1996-07-02
Abstract: There  is  provided  a  method  and  device  for automatically aligning the proximal edges of two or more  appreciably  magnetic  sheets  to  be  connected along abutting edges.  The device preferably includes supports   to   align   the   magnetic   sheets   in substantially  planar  relationship  aligned  relative one  another with  their  proximal  edges  oriented  in approximately  abutting  relationship  and  generally aligned along a predetermined contiguous seam line. At least one of the sheets is to remain moveable on the  supports  relative  to  the  other  sheets.   The alignment  device  further  preferably  includes  an electromagnetic mechanism for simultaneously creating an effective north pole along the proximal edge of one of the supported sheets, and an effective south pole along the confronting proximal edge of the other sheet.    These opposing  poles  cause  a  magnetic attraction between the proximal edges of the sheets which  automatically  pulls  and  aligns  the  proximal edges into intimate contact along their length.  Once aligned in intimate contact, it is preferred that all of these sheets be restrained from further movement so that optimal welding procedures can be completed.

Title: Method of coating glass
Inventor: TERNEU ROBERT
IPC: C23C16/40
Filed: 1991-08-19
Granted: 2002-10-15
Abstract: In methods of forming a coating comprising a pyrolytically formed oxide layer on a travelling hot glass substrate, the substrate is contacted with coating precursor material in the presence of oxygen.      In order to prevent interaction between coating precursor material used for applying an upper coating stratum, and/or to facilitate modification of the optical or other properties of the coating as a whole, an oxide substratum of said coating ("the undercoat") is pyrolytically formed in an incompletely oxidized state by contacting the substrate in an undercoating chamber with undercoat precursor material in the presence of oxygen in insufficient quantity for full oxidation of the undercoat material on the substrate and in that such undercoat is overcoated with an upper coating layer while it is still in an incompletely oxidized state, and while the substrate is still hot, thereby to preserve such undercoat in an incompletely oxidized state.

Patent CA-2059935-C (CA)
Inventor: STEIGERWALD ROBERT LOUIS
IPC: H02M7/10
Filed: 1992-01-23
Granted: 2001-03-27
Abstract: An off-line switching power supply includes an ac rectifier and a dual-output switching converter having one output coupled between the ac rectifier and the input to the dual-output converter in order to provide a high power factor, the other output of the dual-output switching converter providing a do voltage as the power supply output.  The outputs of the dual-output converter are fully decoupled so as to allow independent control of the ac input current and the power supply output voltage. In a preferred embodiment, a full-wave ac rectifier bridge is coupled in series with the second output of the power converter via an input resonant boosting converter. A full-bridge dc-to-ac converter is coupled between the do link and ground for providing an ac signal to excite the boosting converter and for providing another ac voltage through a transformer to an output rectifier to generate a regulated do output voltage.  The amplitude of the regulated output voltage is controlled by pulse width modulation, while active frequency control of the boosting converter is provided to control the amplitude of the ac input current. Alternatively, frequency control of the boosting converter is passive, i.e., depends on the gain characteristics of the boosting converter resonant circuit.  As a result of thecomplete decoupling of the input boosting converter and the power supply output voltage, the off-line switching power supply is capable of drawing high quality current waveforms from the ac source while producing a regulated do output voltage with fast transient response.
