Abstract: An anti-lock braking system incorporates an improved apportioning valve (11) for controlling the behaviour of a rear wheel brake (5) as dictated by the behaviour of a front wheel brake (3) incorporated in a common braking circuit with a master cylinder (1) and a modulator (10). The apportioning valve (11) is so arranged that the level of braking contributed by the rear brake (5) can increase after the level of braking contributed by the front brake (3) has been limited at the adhesion level of the front wheel (4), particularly on surfaces of relatively low co-efficients of friction. 
     The apportioning valve (11) incorporates a piston (14) which is movable in a bore (13) at a cut-in point against the force in a spring (23) in response to pressures acting over different areas (26, 28). This controls operation of a metering valve (17) through which fluid is supplied from the master cylinder (1) to the rear brake (5).

Abstract: Sheet molding compounds are thickened (or maturated) via "in situ" formation of polyureas made from aromatic primary diamines with reduced basicity and diisocyanates. The molding compounds, which can optionally contain mineral fillers such as chopped glass fiber, are generally based upon unsaturated polyester resins having a high percentage of hydroxyl end groups, polymerizable vinyl compounds such as styrene, and the like. The thickened compositions are tack-free and compression moldable after less than one day, typically after less than several hours, into permanently shaped, strong rigid articles, such as automotive body parts. A viscosity plateau is reached and maintained by the maturated compounds of the present invention for extended periods of time, e.g., several weeks.

Title: Process for removing sulfur moieties from claus tail-gas
Inventor: SERRAND WILLIBALD
IPC: B01D53/86
Filed: 1989-03-06
Abstract: Claus tail-gas containing H₂S and SO₂ in a mol ratio of 2:1 is passed in contact with a catalyst-adsorbent bed (19A) at a temperature of 135 to 150°C and a space velocity of 50 to 1500 h⁻¹ whereby elemental sulfur produced by the reaction of H₂S and SO₂ is deposited upon and/or adsorbed on said bed. The resulting sulfurous gas mixture is cooled by indirect heat exchange (26) to a temperature of 120 to 135°C and liquid elemental sulfur is recovered (27,54,55,101), the sulfurous gas (28) thereafter being cooled and diluted by adding cool inert gas (34) thereto to maintain the water partial pressure below the saturation vapour pressure, and the cooled diluted gas mixture is contacted with a bed of catalyst-adsorbent (32A) at a temperature of 90 to 125°C whereby further elemental sulfur is produced by the reaction of SO₂ and H₂S. The elemental sulfur deposits upon and/or is adsorbed on the catalyst-adsorbent and the resulting purified gas (34) is incinerated (37) and discharged (38) to the atmosphere. In one embodiment, the gas from the indirect heat exchange step (26) is contacted with catalyst-adsorbent (30A) at 120 to 135°C before cool inert gas (34) is mixed therewith, elemental sulfur being deposited upon and/or adsorbed on the catalyst-adsorbent. 
     Elemental sulfur is removed from the catalyst-adsorbent beds by a hot, inert purge gas (44,46) which is cooled (19B,52) for sulfur recovery. The purge gas is cooled (52) at the end of the sulfur-recovery step to cool the catalyst-adsorbent beds for a further cycle of sulfur recovery from Claus tail-gas.

Abstract: Data cryptography is achieved in an improved manner by associating with the data cryptography key, a control vector which provides the authorisation for the uses of the key intended by the originator of the key. Among the uses specified by the control vector are limitations on encryption, decryption, authentication code generation and verification, translation of the user's data. Complex combinations of data manipulation functions are possible using the control vectors, in accordance with the invention. The system administrator can exercise flexibility in changing the implementation of his security policy by selecting appropriate control vectors in accordance with the invention. Complex scenarios such as encrypted mail box, session protection, file protection, ciphertext translation centre, peer-to-peer ciphertext translation, message authentication, message authentication with non-repudiation and many others can be easily implemented by a system designer using the control vectors, in accordance with the invention.

Abstract: A special purpose circuit unit, responsive to a special BBD instruction, provides for more efficient execution of program branches required in poll and test type routines used by data processors. This unit can easily be added to almost any contemporary processing system to speed up performance of priority branch operations. It includes: a stack of registers loadable with branch addresses designating locations of branch target instructions, an input register for holding bits representing branch conditions accessible from immediate (programmable) storage, and a programmable priority encoder responsive to the BBD instruction to select an address from the stack in accordance with the position in the input register of a highest priority one of the bits representing an active request for instruction branching. The selected address is used to fetch an instruction representing the start of a program segment for attending to the selected branch condition. Contents of the branch address stack are alterable by program to allow for varying selections of branch routines to fulfil conditions denotable by different sets of bits loadable into the input register. The priority encoder includes a stack of selection control registers which are also loadable by programs, to allow for variability in the priority ordering accorded to the bit positions of the input register. By dynamically loading information into the branch address and priority selection stacks, subject BBD unit can be shared dynamically for resolving sequence branching relative to multiple different classes of conditions or events depending on system requirements. The unit is configurable to execute its priority and branch address selection operations together in a single clock cycle of the system. In pipelined systems, the BBD function can be conveniently accommodated in parallel with other system functions.
