Patent EP-0399387-A3 (EP)
Title: Rotary vane machine
IPC: F04B27/08
Filed: 1990-05-18
Abstract: A vane-type rotary hydraulic machine that comprises 
a housing (12), a rotor (40) mounted within the housing and having a 
plurality of radially extending peripheral slots (42), and a plurality 
of vanes (44) individually slidably mounted in the rotor slots. A 
cam ring (32) within the housing surrounds the rotor and has a 
radially inwardly directed surface (46) forming a track for sliding 
engagement with the vanes. Symmetrical diametrically opposed 
fluid pressure cavities (48) are formed between the cam ring surface 
and the rotor, and fluid inlet (58) and 
outlet (68) passages in the housing 
are coupled to the fluid pressure cavities. Both of the fluid 
inlet and outlet passages comprise housing fluid passages (60, 62) that 
open to side faces of the rotor radially inwardly of the fluid 
pressure cavities, and fluid passages (54, 56) extending radially through 
the rotor between outer ends opening at the periphery of the 
rotor between adjacent slots and an inner end opening axially 
at the side faces of the rotor for communication with the housing 
fluid passage as a function of rotation of the rotor.

Title: Anti-theft case, particularly for compact disc cassettes, video cassettes, and the like
IPC: E05B73/00
Filed: 1990-06-11
Abstract: An anti-theft case, particularly for compact discs, music cassettes, video cassettes, and the like, is provided with movable means (7, 7 min ) for locking a cassette (15) within such a case. According to the invention, the case comprises a box (1) having substantially a parallelpipedal shape, and being provided with an opening (2) for a cassette to be inserted therethrough into its box, which is formed in at least one of the box sides, in such a manner as to leave at least two wall portions (3, 4) which extend from two opposite end-side walls (5, 6) of box (1), and which are longer than the extent of cassette (15) in the direction in which a cassette is inserted into its box. A movable abutment member (7, 7 min ) is provided in the region of one of the two end-side wall portions (3, 4) of the box sides, and is caused to cooperate with one end-side edge of cassette (15), the said movable abutment member (7, 7 min ) being pushed by spring means (10, 10 min ) into its abutting active position, or vice-versa. By a locking and unlocking device (11) the movable abutment member (7, 7 min ) is moved from the said abutting active position into a withdrwan inactive position. The cassette (15) is inserted into its case in an inclined condition, and with the movable abutment member (7, 7 min ) in its inactive position, the cassette is so shifted as to be engaged under the end-side wall portion (4) which is associated with the movable abutment member (7, 7 min ), by being passed thereover, whereupon the cassette (15) is moved backward so as to be engaged also under the opposite end-side wall portion (3), thus uncovering the movable abutment mem ber (7, 7 min ) which is moved into its active position, in which it is caused to cooperate with the associated end-side edge of cassette (15), whereby any such shiftement of cassette (15) is prevented, that may be apt to disengage the same for the two end-side wall portions (3, 4).

Patent EP-0382343-A3 (EP)
Title: Uv-visible monochronometer order subtraction technique
IPC: G01N21/27
Filed: 1990-01-15
Abstract: In an instrument wherein a sample in a solvent with a 
solute is interrogated for absorption by monochromatic light, 
a method and apparatus for electronically measuring and 
subtracting the effect of half order chromatic components is 
disclosed. The light is originally produced by a relatively 
broad spectrum light source having its spectral output 
separated to a monochromatic interrogating beam produced by 
reflection at an angle from a diffraction grating. Inevitably 
present in such diffraction grating produced chromatic light 
are half order light components. The process includes turning 
the diffraction grating with respect to the light source to 
have a primary output in the frequency of the half order 
component of the selected primary monochromatic frequency and 
taking a measure of the system absorption at the half order 
component. System absorption can be taken either by passage 
through the system free of soivent, solute and sample or 
alternatively passage through a reference cell containing 
solvent and solute within the system. The diffraction grating 
is then turned with respect to the light source to have a 
primary output in the primary monochromatic frequency. The 
ratio of primary monochromatic frequency to half order 
transmission (a known constant for any diffraction grating) is 
utilized to calculate the half order component in any selected 
primary monochromatic frequency. Thereafter, and for a sample 
in a solvent and solute, the log of the ratio of absorption of 
all light less the calculated half order light absorption for 
the sample in the solute and the solvent over the absorption 
of all light for the system less the calculated half order 
light absorption for the system is taken to describe relative 
light absorption. It is preferred to use a reference cell for 
the system absorption measurement to describe relative light 
absorption between the sample cell and reference cell. 
Utility can be present in comparing the absorption between 
 
 
differing solvents, solutes or samples. The apparatus and 
method finds preferred utility in observing centrifugation 
induced separation through windows in a spinning rotor during 
the process of separation.

Title: Video control circuit
IPC: H04N5/45
Filed: 1990-04-12
Abstract: A contrast control circuit (54) develops a video gain 
control signal for continuously varying the video gain of a video 
signal to adjust the contrast of the video signal and limit beam 
current. The contrast control circuit may comprise an auto 
contrast control (24) responsive to video signal peaks, a contrast 
limiter (70) responsive to a beam current control signal related to 
average picture intensity and a manual control (20). A brightness 
modulator (72) is also responsive to the contrast control signal 
for continuously adjusting the brightness of the video signal 
inversely with the contrast. The brightness modulation is 
especially useful as part of a pix-in-pix video control circuit, 
further comprising video sources (30, 32) for first and second 
video signals and a selector (34) for alternatively feeding the 
first and second video signals to a video amplifier (52) to form a 
primary picture with an inset secondary picture.

Abstract: The invention relates to a rubber tire composed of
carbon black reinforced rubber carcass and having a
rubber tread which is quantitatively reinforced with an
electrically non conductive filler pigment such as, for
example silica, and which, in turn, is at least
partially, and preferably substantially, enveloped by
carbon reinforced rubber of a consistent, or continuous,
composition. 
     In one aspect, said rubber layer extends across at
least a portion of the outer surface of the tread which
is normally intended to be ground-contacting and envelops
both the ends and optionally an inner surface of a tire
tread, which may be a tread cap (7) of a tread of
cap/base construction. 
     The said rubber layer connects with at least one
other carbon black reinforced rubber component of the
tire in a manner to provide a path of reduced electrical
resistance from said layer on the outer surface of the
tread to the bead portion of the tire carcass and,
therefore, such a path from the vehicle to a road
surface. 
     In one aspect, it is envisioned that the tread
construction may be a dual extrusion of (i) said tread
rubber, and (ii) said rubber layer composed of tread
wings (8) and associated rubber layer extension (9) over
the outer surface of the tread.
