Title: Method and apparatus for optimally autocorrelating an fsk signal
Inventor: TJAHJADI TARUNA
IPC: H04L27/152
Filed: 1991-02-06
Abstract: An autocorrelator for FSK signals. An FSK signal, incoming an a telephone line is filtered by a bandpass filter (13) and sampled by an A/D converter (14). A sample clock (15) provides a fixed sampling frequency, FS. A first interpolating filter (20B) provides selectable delays which are non-integer multiples of 1/FS, and an integer delay (25) provides selectable delays which are integer multiples of 1/FS. The delayed signals are multiplied by a multiplier (26) and then filtered by a low pass filter (27) to provide a filtered autocorrelated signal. A second interpolating filter (20A) provides for reduced jitter in the band timing by increasing the number of samples provided to the decision logic (23). The decision logic (23) provides the decoded data output.

Title: Syndiotactic 1,2-polybutadiene synthesis in an aqueous medium
Inventor: BELL ANTHONY J
IPC: C08F2/22
Filed: 1991-02-19
Abstract: Pure syndiotactic 1,2-polybutadiene is a thermoplastic resin which has double bonds attached in an alternating fashion to its polymeric backbone.     Films, fibers and molded articles can be made utilizing syndiotactic 1,2-polybutadiene. It can also be blended into rubbers and cocured therewith. Syndiotactic 1,2-polybutadiene can be made by solution, emulsion or suspension polymerization. It typically has a melting point which is within the range of about 195°C to about 215°C. However, it is often desirable for the syndiotactic 1,2-polybutadiene to have a melting point of less than about 195°C. This invention discloses a process for preparing syndiotactic 1,2-polybutadiene having a melting point of less than about 195°C which comprises: polymerizing 1,3-butadiene monomer in an aqueous medium in the presence of (1) a catalyst composition which is made by reacting (a) at least one cobalt compound (b) at least one organoaluminum compound, and (c) at least one conjugated diene; (2) carbon disulfide; and (3) at least one modifier selected from the group consisting of (a) 4-(alkylamino)benzaldehydes, (b) 4-(dialkylamino)benzaldehydes, (c) 2,4-di-(alkoxy)benzaldehydes, (d) 2,6-di-(alkoxy)benzaldehydes, (e) 2,4,6-tri-(alkoxy)benzaldehydes, and (f) 4-(1-azacycloalkyl)benzaldehydes.

Title: Pharmaceutical compositions having depigmentating and antiphotoageing activity
Inventor: CAPUTO RUGGERO
IPC: A61P17/00
Filed: 1991-02-19
Abstract: Abstract PHARMACEUTICAL COMPOSITIONS HAVING DEPIGMENTATING AND ANTIPHOTOAGEING ACTIVITY    The object of the  present invention is a product based on a trans-retinoic acid (tretinoin) and azelaic acid combination having depigmentating effect and, more generally, antiphotoageing effect.   After   clinical   and   instrumental   comparative analysis  (clinical  and photographic  reports  and skin mould profilometry), the action on physiological and/or photoinduced skin ageing obtained with the combination of  the  invention  has  been  compared  with  the  one noticeable  after  the  treatment  with  azelaic  acid or retinoic acid only. Better results were obtained using the azelaic-retinoic combination.     The depigmentating  action  of  the  combination  is superimposable to the one observed by using separately the two active ingredients, but it can be achieved in a surprisingly shorter time (from six to three months).

Title: Four-way valve
Inventor: PHILLIPS EDWARD H
IPC: B62D5/083
Filed: 1990-03-19
Abstract: A four-way open-center rotary control valve (210, 260) is provided which features internally generated hydraulic reaction torque.  The hydraulic reaction torque is generated between inner (212, 262) and outer valve members (214, 264) having multiple inlet (220, 222) and return control orifices (232, 234) formed at differing radii. The return control orifices are formed at larger radii than the inlet control orifices - thereby resulting in expanded values of radially disposed area on either side of ridges which partially form the return control orifices. Thus, differential output pressure present in first and second output zones, which are alternately disposed between pairs of the inlet control orifices and pairs of the return control orifices, generates the hydraulic reaction torque via the product of the differential pressure, the expanded values of the radially disposed area and effective radius of the radially disposed area. Generally, the first and second output zones are coupled to either side of a double acting utilization device via controlled orifice flow restrictors (488), also of the present invention. The controlled orifice flow restrictors comprise an oversize orifice (494) which is selectively filled by a spring-loaded contoured valve member (496).

Abstract: - i -MANUAL OPERATOR FOR AN ELECTRICAL SWITCH                   Abstract of the Disclosure A manual  operator for opening and closing an electrical switch, including a switch-driving element, a relatively rotatable handle element, and a resilient transmission, e.g., a leaf spring or springs, extending between the two elements.  An abutment is fixed to one of the elements and a follower is fixed to the other, the  abutment  engaging  the  follower  only  after the  resilient transmission has been tensioned by rotation of the handle element.          When the driving element engages a portion of the switch mechanism, initial rotation of the handle causes the resilient transmission to be tensioned and the abutment to engage the follower.  Further rotation of the handle is transmitted through the abutment and follower to the driving element to initiate the movement of the switch  mechanism,   following  which  the  tensioned  resilient transmission instantly shifts the switch mechanism through the remainder of its movement to snap the switch open or closed.  A latch optionally rigidly interconnects the handle and driving elements to bypass the resilient transmission and transmit any rotation of the handle directly to the driving element.
