Inventor: WINGEN RAINER
IPC: C09K19/58
Filed: 1988-04-15
Abstract: Optically active and mesogenic 1,3-dioxolane-4-carboxylic esters are suitable for use as dopants in liquid crystal mixtures. They lead to liquid-crystalline ferroelectric phases having short response times and to electroclinic phases having large electroclinic coefficients. Their particular advantage is that they induce a helix of very large pitch, so that there is no need for any helix compensation by other dopants. Moreover, the 1,3-dioxolane-4-carboxylic esters exhibit high UV stability.

Title: Method for producing hard protection coatings on articles made of aluminium alloys
Inventor: SHARTROV ALEXANDR SERGEEVICH
IPC: C25D11/06
Filed: 1997-12-17
Granted: 2002-11-07
Abstract: The proposed invention relates to the sphere of plasma electrolytic oxide coating of aluminium alloys. The method incorporates anode-cathode oxide coating in an alkaline electrolyte at a temperature of 15-50 DEG C, using 50-60 Hz frequency alternating current. In the initial stage of the process oxide coating is carried on for 5-90 seconds at a current density of 160-180 A/dm<2>, then the current density is dropped to 3-30 A/dm<2> and the process is continued in a regimen of spontaneous diminution of power demand without on-line adjustment of the regimen until the set coating thickness is achieved. The alkaline electrolyte used is an aqueous solution of alkaline metal hydroxide at 1-5 g/l, an alkaline metal silicate at 2-15 g/l, an alkaline metal pyrophosphate at 2-20 g/l and peroxide compounds at 2-7 g/l (in terms of H2O2 - 30%). The proposed method enables the protective properties of ceramic oxide coatings to be enhanced through an increase in the micro-hardness, density and strength of adhesion to the substrate without any additional energy outlay or time required.

Title: Multiplexed hydraulic control systems
Inventor: LEESON PLATO J
IPC: G05B19/46
Filed: 1990-01-31
Granted: 1993-11-09
Abstract: Abstract Of The Disclosure A time division multiplexed (TDM) hydraulic control system having a plurality of channels, each channel having a servo actuator.  Electrical demand signals are arranged in TDM sequence and applied to a single multiplexed pilot valve so that the pilot valve produces a plurality of hydraulic signals. Commutator means are associated with the pilot valve for distributing the hydraulic signals to the associated channels.  In order to achieve useful output flow rates in the channels, each channel includes a second stage valve which integrates the hydraulic signals for its channel to produce an output flow rate which is a function of the integrated signal.  The flow rates are continuously produced (as compared to the multiplexed output signals) and are coupled to actuators in the channels for controllably adjusting the position thereof. Feedback means associated with the actuators includes rate feedback for stabilizing the multiplexed control loops.

Abstract: ABSTRACT OF THE DISCLOSURE A modular tile (10) for interlocking with other similar tiles to form a floor covering which provides enhanced traction at its playing surface and improved tolerance to sudden lateral movement.  The tile comprises a plastic support grid having rectangular configuration bounded by a perimeter wall (12) and including a repeating pattern of intersecting cross members (13) with interstitial openings (15) formed inbetween.  A plurality of support legs (16) are coupled to a base side of the cross junctions (14) in general perpendicular orientation.  Interlock structure (20, 21) is coupled to and extends outward from the perimeter wall to enable removable attachment with other modular tiles of similar design.  The interlock structure provides a continuous, uniform displacement gap (23) between adjacent perimeter walls (12) which establishes a separation distance between the range of 0.5 to 2 millimeters, and also provides a yielding response to absorb lateral forces.  A continuous sheet of plastic (18) provides a flat surface cap to the tile, which enables its use as part of a continuous flat athletic floor covering.

Title: Wideband digital equalizers for subscriber loops
Inventor: CRESPO PEDRO MIGUEL
IPC: H04B3/14
Filed: 1990-08-13
Granted: 1995-06-06
Abstract: A digital decision feedback equalizer is disclosed in which compensation for the post-cursors of the impulse response of the transmission channel is divided up into two regions. A first region encompasses the initial rapidly changing unpredictable transient response, possibly oscillatory, of the transmission channel. A fast acting, close-tracking linear filter is used to compensate for this largely unpredictable initial transient. The second region of the impulse response is the slowly changing, easily predictable asymptotic tail of the impulse response. This second region can be compensated for by a relatively slowacting, simple pole-zero filter. Together, the two equalizer sections provide anoverall equalizer design far less complicated and less expensive than an equalizer based on a single linear compensating filter. A finite impulse response (FIR) filter is used to compensate for the unpredictable, rapidly changing initial transient portion of the impulse response, while an infinite impulse response (IIR) filter is used to compensate for the slower acting tail portion of the impulse response.

Abstract: An electrode for a plasma carburizing furnace is disclosed which is adapted to provide a dynamic gas shroud for inhibiting the buildup of carbon soot on the insulating elements of the electrode.  The reduction of carbon soot buildup on the insulating components dramatically reduces the frequency of electrical short-circuits across the insulating components, thereby increasing the availability of the furnace for processing of workpieces.
Patent CA-2031140-C (CA)
Inventor: POLLACK JEREMY D
IPC: H04N5/445
Filed: 1990-11-29
Granted: 1995-04-25
Abstract: A sleep timer function for consumer electronics equipment automatically turns off the equipment after a predetermined time interval. During the final two minutes of the sleep time interval, the sleep timer circuitry gradually decreases the volume or provides a visual indication that automatic turn off is imminent. The reception of any modulated infrared (IR) signal, transmitted from any source, during the timer period is interpreted by the sleep timer function controller as an indication that the user is still awake. In response, the controller resets the count of the sleep timer to the maximum period, thus deferring the automatic turn off of the equipment.

Abstract: A CDMA cellular radio-telephone system (FIG. 2) has switching systems (201) synchronized to public telephone network (100) timing signals (600), and radio telephones (203) and cell base stations (202) synchronized to a different clock (1000). Transmission delays between the cell base stations and the telephone network are variable. Switching systems include digital communications interfaces (264) to the telephone system, whose connections to the telephone system are synchronized to the telephone system, and whose connections to the cells arenominally also synchronized to the telephone system but whose processor (602) operates for each call within predefined windows (1302, 1402) of phase relationships to the operation of the cell that is handling the call, and occasionally adjusts(FIGS. 13-16) its phase relationships to the operation of the telephone system to achieve and maintain its operation within the predefined windows. Packet-switched communications (350) between the cells and the switching systems absorb the phase relationship fluctuations and the timing adjustments in inter-packet intervals. Circuit-switched digital communications between the switching systems and the telephone system absorb the timing adjustments by means of vocoder (604)-implemented slips --bit insertions or deletions-- in the communications traffic bit stream.
