Abstract: A loading arrangement for loading fluids onto a ship at sea comprises a coupling manifold on board said ship. A pulling line which is connected with a winch on board said  ship  and  comprises  a  loading  fork  with  two diverging parts which at a respective end are connected with coupling head, may be guided on board and towards said winch,  via a guide pulley which is mounted on board said ship to be movable in a controlled manner in the direction of pulling line towards and away from said winch. Coupling manifold is mounted to be slewable about  a horizontal  axis,  so  that  it may be  slewed towards  and  away  from  the  loading  fork.  Coupling manifold has a guiding means in the shape of a curved screen,  which in vertical  elevation has a trapezoid shape adapted to  the triangular area of loading fork between the two parts. When loading fork is brought into a position outside coupling manifold by the aid of winch,  the  coupling  manifold  may  be  slewed  in  a direction towards the loading fork so that the guiding means,  i.e.  curved screen,  contacts loading fork and fixes  the  latter  in  the  fork  plane.  Cooperation between screen and fork is facilitated by the fact that guide  pulley  is,  as  mentioned,  displaceable  in  the direction of the pulling line, towards and away from the winch.

Abstract: A method for setting an ophthalmic lens in a pair of goggles having a flat front transparent lamina  for  permitting  vision  and  also  having  a shielding rim surrounding the lamina extending towards the face of the wearer for the abutment thereon is characterised by a lens secured inside the shielding rim adjacent the lamina.  The ophthalmic lens has a flat plane adjacent the lamina separated therefrom by an  air  gap.    A  first  silicone-base  caulking  is deposited between the periphery of the lens and the shielding   rim   up   to   a   level   substantially corresponding to the thickness of the air gap.  This first caulking has a viscosity sufficiently sag-proof to maintain the caulking at the periphery of the gap during its hardening.   A second caulking having a lower viscosity is deposited on the top of the first caulking up to a level corresponding to the top of the lens.  The caulking is selected to be free of toxic and corrosive gas.  The lens has a peripheral groove to improve the adherence of the second caulking.

Abstract: The present invention relates to a contrast correction device for correcting the contrast of an image formed by video signals.  The device includes a brightness/darkness detecting circuit for detecting a tone level of the image and for producing a bright signal when the tone level is greater than a predetermined brightness, and a dark signal when the tone level is less than a predetermined darkness.  A correction circuit is provided for correcting a luminance signal by a negative gamma correction in response to the bright signal, and a positive gamma correction in response to the dark signal.  Thus, the contrast of bright areas in the image are enhanced when the bright signal is produced, and the same are suppressed when the dark signal is produced.

Abstract: Abstract of the Disclosure A portable telephone set having a cover attached rotatably to a body.  When closed, the cover covers and protects a switch portion of the telephone set, while when opened, it is held in a stable position at a predetermined angle relative to the body by means of a cover holding mechanism.  The cover is held with respect to the body by the cover holding mechanism so that the cover is disengaged from the body when it is about to be opened forcibly beyond an allowable range of its rotation.  Since the cover when opened can function as a sound collector, it is possible to provide a microphone on the body side and attain the reduction in size of the portable telephone set.

Abstract: RD-20,855 TWO-STAGE RESONANT STARTING CIRCUIT FOR AN ELECTRODELESS HIGH INTENSITY DISCHARGE                      LAMP                            Abstract A starting circuit for an electrodeless HID lamp provides a two-stage resonant starting signal to a gas probe starter of the type comprising a starting chamber which contains a relatively low-pressure gas and is attached to the outer wall of the arc tube.  The starting circuit comprises a resonant LC circuit of variable impedance including the series combination of a variable inductance and the parasitic capacitance between the gas probe starter and the excitation coil.  In operation, the resonant circuit is tuned to a predetermined value so that, upon application of an RF signal to the excitation coil, resonant operation of the starting circuit results in the application of a sufficiently high starting voltage to the starting chamber to ignite a low-current glow discharge therein.  Once the glow discharge is ignited, the starting circuit is retuned to ensure that a sufficiently high starting voltage is capacitively coupled to the arc tube to ionize the arc tube fill and initiate an arc discharge therein.

Abstract: Apparatus for and a method of digital signal processing utilises a technique known as sub-band decomposition and reconstruction. A plurality of input channels are provided each of which is mixed with a vernier frequency correction. In a multiplexer implementation, an FFT weighted overlap-add demultiplexer (c) is provided for decomposing each input channel into sub-bands. The sub-band outputs are decimated by a factor (d) to the common input sampling rate of a multiplexer, the sub-bands from each channel then being passed into the appropriate ports of an FFT weighted overlap-add multiplexer (f) by means of a switch matrix (e). The multiplexer (f) reconstructs the individual channels, interpolates each channel up to the output sampling rate of the FDM signal, mixes each channel up to its assigned carrier frequency in the FDM and multiplexes the channels.       This provides a computationally efficient architecture with the flexibility to accommodate channels of differing bandwidths.

Abstract: A spring applied - hydraulically released (SAHR) type wet disc brake for a wheeled vehicle having a large braking torque and energy absorption capacity. The brake unit includes a piston housing in which an annular piston is mounted for reciprocal movement towards and away from a disc housing. The disc housing defines a disc chamber in which a plurality of interleaved non-rotating and rotating discs are disposed. A pressure plate disposed on one side of the disc pack is mounted for reciprocating movement towards and away from the disc pack and is operative to apply clamping forces to the discs in order to generate braking torque. A plurality of biasing springs urges the pressure plate towards engagement with the disc pack. Pressurized fluid applied to the piston maintains the pressure plate in a released position. Selective reduction of pressure to the piston effects braking action. A piston-to-reaction plate seal inhibits coolant flow between an inner face of the pressure plate and the adjacent disc. A pressure plate seal carried by a periphery of the pressure plate sealingly engages the disc housing and inhibits coolant flow from the disc chamber, across the pressure plate. A coolant inlet distributes coolant throughout the periphery of the disc chamber. Coolant then flows between the interleaved rotating and non-rotating discs toward a central region from where it is exhausted through one of the spring chambers. Aligned locations defined by teeth removed from the rotating discs together with a wheel hub member form coolant passages. The pressure plate includes a plurality of standoffs that extend across the disc pack and are engageable by the piston located on the opposite side of the disc pack. The piston applies forces which oppose the spring applied forces.
