Title: Anti-skid system for the wheels of vehicles
IPC: B60T8/66
Filed: 1971-09-29
Abstract: 1363484 Anti-skid systems WABCO WESTINGHOUSE GmbH 29 Sept 1971 [14 Oct 1970] 45342/71 Heading F2F In an anti-skid system, incipient locking of each wheel is detected by comparing its speed with a reference value representing vehicle speed and derived from the rotational speed of the most rapidly rotating of the four wheels VL, VR, HL, HR through a signal-shaping circuit 5 operating between preset limits of vehicle deceleration. Each wheel drives a pulse generator 2a whose signal is converted to D.C. at 3a and is fed into the shaping circuit through a diode 4a. This ensures that only the highest signal, i.e. that from the fastest wheel which is least likely to be skidding, is fed to the circuit 5 to represent vehicle speed. This signal is compared with that of each individual wheel at 11a, 11b, 11c or 11d, and any difference passes through a logic circuit to the brake control valve to relieve the braking pressure. A non-driven wheel VL is also provided with an acceleration transducer 16 comprising a tachometer signal differentiator 6a, an attenuator 8a and a trigger 10a, preferably incorporating damping to produce delay in the transmission of a control signal '+b' to the logic circuit 12a. The system depends on the assumption that at least one wheel is not skidding. The function of the transducer circuit 16 is to increase the likelihood that arbitrarily selected wheel VL retains adhesion, by blocking any increase in brake pressure until the transducer output has dropped below a certain level. Details of the logic circuit for achieving this are described with reference to Fig. 2 (not shown) but its function is to prevent re-application of braking to this wheel until its acceleration is at a low level, e.g. zero, signifying that adhesion is restored. The other wheels are then compared with this, as described. The system is stabilized by damping and by a timer (17) and a shift register (26) acting as a counter of application cycles.

Title: Improvements in or relating to the manufacture of polyols
Inventor: CHAPMAN JOHN FREDERICK
IPC: C08G18/50
Filed: 1962-12-03
Abstract: Rigid, flexible, cellular or homogeneous polyurethanes may be made by reacting an organic polyisocyanate with a hydroxyl group-containing oxyalkylated aromatic amine made by reacting an aromatic amino compound containing at least two primary or secondary amino groups, at least one of which is directly attached to an aromatic nucleus, with from 0.1 to 0.6 molecular proportions of alkylene oxide for each equivalent proportion of active hydrogen in the amino compound, incorporating an alkaline catalyst which is then reacted with the hydroxyl groups with elimination of water and subsequently continuing the addition of alkylene oxide. The polyisocyanates include aliphatic diisocyanates, aromatic diisocyanates, cycloaliphatic dissocyanates, triisocyanates and reaction products of a diisocyanate with polyhydric alcohols. Foamed polyurethanes may be made by carrying out the reaction in the presence of water and/or a low boiling point liquid such as a fluorinated alkaline.  Suitable catalysts include tertiary amines, organotin compounds, potassium acetate, iron acetylacetonate, stannous carboxylates and lead carboxylates. Surface-active agents may be present including alkyl and aryl polysiloxanes, siloxane-oxyalkylene block copolymers, oxyethylated phenols, oxyethylated fatty alcohols and block copolymers of ethylene and propylene oxides.ALSO:Hydroxyl group-containing oxyalkylated aromatic amines are made by reacting an aromatic amino compound containing at least two primary or secondary amino groups, at least one of which is directly attached to an aromatic nucleus, with from 0-1 to 0-6 molecular proportions of alkylene oxide for each equivalent proportion of active hydrogen in the amino compound, incorporating the alkaline catalyst which is then reacted with the hydroxyl groups of the partially oxyalkylated amino compound with elimination of water and subsequently continuing the addition of alkylene oxide until an oxyalkylated aromatic amine having the desired molecular weight is obtained.  Suitable amino compounds are listed, 2: 4- and 2: 6-diaminotoluenes and mixtures thereof being preferred. Alkylene oxides include ethylene oxide, 1: 2-propylene oxide, 1: 2-butylene oxide, 2: 3-butylene oxide and mixtures thereof. Temperatures of from 50 DEG  to 150 DEG  C. and pressures of up to 80 p.s.i. may be employed in reacting the amine and alkylene oxide. Alkaline catalysts include alkali metal hydroxides and alcoholates and quaternary ammonium hydroxides. The alkylene oxide reacted in the final stage may be the same or different from that used prior to incorporation of catalyst.  The oxyalkylation products may be rendered alkali-free by treatment with acid followed by filtration or treatment with active carbon or an absorbent earth followed by filtration.  A detailed example is given.

Abstract: 1512225 Fish breeding tanks AIR PRODUCTS & CHEMICALS INC 15 Oct 1976 [31 Oct 1975] 45571/75 Heading A1A [Also in Division Bl] An apparatus for dissolving oxygen in fish farming water, comprises a surface aerator 4 covered by a movable hood 3. In operation, air is first expelled from the hood through a vent 11, oxygen is then passed into the tank through a diffuser 8 via a motorised valve 10 which is closed after a preset time, a sensor 18 then generates a signal which is compared with a signal in a control box 16 to determine whether sufficient oxygen has dissolved in the water, if sufficient has not been dissolved, a motor 5 is actuated to rotate the surface aerator until the concentration of oxygen in the water reaches the desired level and then the motor is deactuated. If the desired level is not reached after a predetermined time, e.g. 50 minutes, the gaseous mixture in the hood is expelled through the vent 11. In a second embodiment (Fig. 2 not shown) the concentration of oxygen in the hood is measured by a sensor (21) within the hood and when the concentration falls below a predetermined level the hood is vented. In a third embodiment (Fig. 3 not shown) the concentration of oxygen in the hood is measured indirectly by a level sensor (22) within the hood and which causes the hood to be vented when the sensor touches the water. In a fourth embodiment (Fig. 4 not shown) the submersible motor is replaced by a motor supported above the tank and having a drive shaft (23) passing through a gas tight bearing in the hood. In a fifth embodiment the hood is provided with floats (25) and oxygen is fed through a pipe (26) directly into the hood. As oxygen is dissolved in the water the level of water within the hood 3 rises relative to the level of water outside the hood 3. When the oxygen concentration falls to a predetermined level a vacuum is applied to the vent 11 until the hood is flooded.
