Title: Resolution of (cis-1,2-epoxypropyl)phosphonic acid into its optically-active forms
IPC: C07F9/14
Filed: 1968-10-25
Abstract: A diastereoisomeric salt of an antipode of (cis - 1,2 - epoxypropyl)phosphonic acid is obtained by reacting a mixture of such antipodes or a salt thereof with an optically active salt-forming compound, and separating and recovering the said diastereoisomeric salt. The optically active salt-forming compound is preferably an optically active base and may be used in an amount sufficient to form the optically active salts of one or both ( + ) and (-) enantiomers. When the salt of one enantiomer is formed the other enantiomer can be recovered from the mixture remaining after separation of the diastereoisomeric salt and when both salts are formed, one of the salts is first separated and the other salt is then recovered. The diastereoisomeric salts formed may be converted to the free (cis - 1,2 - epoxypropyl) phosphonic acid or to a different salt thereof, e.g. to an alkali metal- or alkaline earth metal salt. The process can also be carried out by reacting a mixture of the enantiomers with a mixture of an optically active base and an optically inactive salt-forming base and separating the optically active base salt of one of the enantiomers from the resulting reaction mixture, at least one-half mole of the optically active base being preferably used per mole of the enantiomers. In this procedure the two bases may be added to a solution of a mixture of the antipodes in a solvent and the optically active salt of one of the enantiomers separated from the reaction mixture. Thus the (+) - [alpha] - phenethyl - ammonium (-)(cis - 1,2 - epoxypropyl)phosphonate crystallizes from an aqueous solution of a mixture of (+) - [alpha] - phenethylamine and triethylamine salts of the racemic phosphonic salt. The optically active bases may be for example amines, hydrazines, imines, imino-esters, hydrazides, phosphines, biphosphines, phosphonium, stibonium or sulphonium compounds, stibines, arsines, alkaloids (e.g. (-) quinine), amino steroids or amino acids and several suitable bases are specified. Optically active allenes, spiranes, biphenyls, cycloalkenes and certain substituted ethanes may also be used as saltforming compounds. The diastereoisomeric salts can be separated by fractional crystallization from suitable solvents, especially C 1 -C 5 alkanols or aqueous C 1 -C 5 alkanols, or by chromatography or by the use of ureas, thioureas, or clathrates to form inclusion products with one of the diastereoisomeric salts.

Patent ES-412452-A1 (ES)
Title: Mechanism for the anti-locking braking of a wheel of a motor vehicle
IPC: B60T8/42
Filed: 1973-03-08
Abstract: An anti-locking braking system for a wheel of a motor vehicle in which a first valve is actuated by a sensing device when the wheel is tending to lock and blocks the supply of fluid under pressure to the brake cylinder and allows the pressure fluid from the cylinder to exhaust via a path including an accumulator whose volume can be increased by the pressure of the exhausting fluid overcoming spring pressure. Upon the volume of the accumulator exceeding a predetermined value a second valve operates to reduce the rate at which the pressure of the exhausting fluid falls. Thus the pressure drop in the cylinder is at first relatively large and subsequently more slow which reduces the chance of jerking of the vehicle.

Title: Torque responsive electric switch assembly
IPC: F16D7/04
Filed: 1976-03-20
Abstract: The safety coupling has two parts (1, 9) which transmit the torque to one another, can be rotated from an operating position in a limited manner with respect to one another against a restoring force while maintaining the same mutual axial position and are coupled to one another via an engagement part (11). The engagement part is guided in an axially displaceable manner on the first part (1) and is held engaged with the second part (9) by a spring (18), via a cam track (8) which rises axially from the operating position in the circumferential direction. During displacement from the operating position along the cam track, the engagement part operates an electrical switching device (20). The second part (9), which transmits the torque, encloses the engagement part (11) together with the cam track (8), the spring (18) and the electrical switching device (20). The critical parts of the coupling are thus protected. If the safety coupling is used as an opposing bearing for a drive motor, then the motor can automatically be disconnected on reaching the switching torque. In this case, the coupling maintains a positive lock.

Title: Steering control for an integrated brake and steering system
IPC: B62D5/08
Filed: 1979-03-30
Abstract: A steering mechanism for use in an integrated brake and steering system. The steering mechanism has a driver gear connected to a rack mechanism by a pinion member. The driver gear is connected to a gear attached to a steering shaft by a linkage member. A carrier member attached to a rotary valve holds first and second sprocket wheels taut against the linkage member. A steering input signal applied to the steering shaft by an operator creates a steering torque in the linkage member. The steering torque causes the rotary valve to move and restrict the communication from a source of fluid to develop a pressure differential across the rack mechanism. This pressure differential moves the rack and provides the driver gear with an operational rotary torque. This operational rotary torque is transmitted by the linkage to the gear on the shaft to provide a power assist in the operation of the steering gear connected to the wheels of a vehicle.
