Patent ZA-843248-B (ZA)
Title: Brake system incorporating a stepping motor
Inventor: WASHBOURN JACK
IPC: B60T8/36
Filed: 1984-05-01
Abstract: An electro-pneumatic brake system in which an electric brake demand signal controls the energisation of a stepping motor (B). The shaft (2A) of the motor is threadedly engaged with a captive nut (2) which bears against an abutment carried by a brake controlling valve (3, 4), the opening of which determines brake actuating pressure downstream of the valve (4). Rotation of the motor (3) therefore directly controls the brake pressure by movement of the valve (4).

Title: Catalyst activation
Inventor: POST MARTIN FRANCISCUS MARIA
IPC: C07C1/04
Filed: 1985-07-18
Abstract: During the activation of Co/Zr/SiO2 catalysts by contacting them with a H2-containing gas at a temperature between 200 and 350 DEG C and a H2 partial pressure between 0,001 and 75 bar, the H2 partial pressure is gradually or stepwise increased from an initial value (PH2) to an ultimate value (PH2)U in such a way that (PH2)U &sccue& 5x(PH2)i. The time required for the activation can be drastically reduced (to about 10 hours or less) by carrying out the activation as described hereinbefore as a result of which catalysts with an improved activity and selectivity are obtained for the conversion of a mixture of CO and H2 into hydrocarbon.

Title: Process for hydrating soft contact lenses
Inventor: KINDT-LARSEN TURE
IPC: B29D11/00
Filed: 1991-04-16
Abstract: A process for releasing leachable substances from a polymeric contact lens blank. The contact lens is confined in a cavity within a carrier to permit the hydration of the lens without permitting it to invert or roll over.

Patent ZA-953655-B (ZA)
Title: Compounds
Inventor: DAVISON BRUCE EVERETT
IPC: C07C233/27
Filed: 1995-05-05
Abstract: The present invention relates to compounds which are useful as sunscreens. The compounds persist on the skin for much longer than conventional sunscreens because they comprise a Michael acceptor linked directly or indirectly to a chromophore. The Michael acceptor is capable of undergoing a conjugate addition reaction with thiol groups present in cysteine residues of keratin and thus the compound is chemically bound to the skin and will not be removed by immersion in water.

Filed: 1997-05-12
Abstract: PCT No. PCT/DE97/00740 Sec. 371 Date Nov. 13, 1998 Sec. 102(e) Date Nov. 13, 1998 PCT Filed Apr. 12, 1997 PCT Pub. No. WO97/43556 PCT Pub. Date Nov. 20, 1997The conical clamping set (100) serves, for example, to connect a shaft (1) with a hub (3) and is arranged in the radial clearance (5) between the cylindrical outer-circumference surface (2) of the shaft (1) and the cylindrical inner-circumference surface (4) of the hub (3). It includes inner conical rings (11, 12) with a cylindrical inner-circumference surface and a conical outer-circumference surface (8', 8''), as well as a thin-walled external conical ring (10, 18', 18'') with conical, inner-circumference surfaces (7', 7'') fitting onto the outer-circumference surfaces (8', 8'') of the inner conical ring (11, 2) and a cylindrical outer-circumference surface (6) intended for application on the inner-circumference surface (4) of the hub (3). Axial clamping screws (19) are distributed over the circumference; the conical rings (11, 12) can be axially pulled against each other by tightening the clamping screws. Because of a radial stepping down (24) or circumference slot, the axial extension of the zone (21) of the cylindrical outer-circumference surface (6) of the external conical ring (10), in which the radial clamping forces are transferred to the inner circumference of the recess (4) of the hub (3), is smaller than the axial extension of the zone (35), in which the radial clamping forces act against the outer circumference (2) of the shaft (1), so the surface pressure on the surfaces (4, 6) is increased.

Title: Method of standby operation in a mobile telephone
Inventor: ROMAO FERNANDO
IPC: H04W52/02
Filed: 2000-03-20
Granted: 2003-12-24
Abstract: In order to reduce current consumption in a mobile telephone, a slow clock signal is used while the mobile is in a standby state. The circuit providing the slow clock signal is calibrated by the circuit providing the fast clock signal before it is deactivated. Data received from the network is used to determine a known period of time delta between a first date T<SB>0</SB> and second date T<SB>1</SB>. The number of time periods of the fast clock during one period of the slow clock N is determined. A value of the duration delta is divided by the number N and a number M is obtained, M comprises an integer part E and a decimal part D. m periods are counted with the fast clock signal, where m<n with n equal to D x N, between the date T<SB>0</SB> and a first edge of the slow clock signal after the date T<SB>0</SB>. A value r of the remainder of the subtraction between m and n is stored in the data memory of the mobile. The mobile is then placed in a standby state, E periods are counted with the slow clock signal, r periods are counted with a fast clock signal. The mobile is subsequently placed in an active state.

Title: A communication system and method of allocating resource thereof
Inventor: THOMAS HOWARD
IPC: H04B7/26
Filed: 2002-07-24
Granted: 2005-12-21
Abstract: A system for allocating resource in a cellular communication system (200) having cell specific spreading codes. An interference processor (239) identifies that a detrimental interference relationship exists between a first group of subscriber units (211, 215, 219). A code allocator (241) allocates a common spreading code to the first group of subscriber units (211, 215, 219) thereby creating a shared resource. A resource allocator (243) then allocates resource of the shared resource between the subscriber units of the first group (211, 215, 219) and resource of the cell specific spreading code to the remaining subscriber units. Joint detection is used for the subscriber units (211, 215, 219) of the first group of subscriber units whereby inter-cell interference is significantly reduced. The invention is applicable to a plurality of communication systems using cell separation spreading codes and in particular to UMTS TDD communication systems.

Abstract: A control head for a thermostatic valve is disclosed which comprises a housing, within which is contained a sensing element (100). The sensing element (100) has a body and an actuating member, the actuating member being operative to move along an axis (A) with respect to the body in response to change in ambient temperature. There is a carrier (102) within the housing. There is further provided connecting means (42) whereby the housing can be secured to a flow valve (10). The body of the sensing element (100) is disposed on the carrier (102) and the actuating member of the sensing element (100) projects from the body such that it can operate a flow valve (10) to which the control head is attached. A user control (61), which may be constituted by part of the housing, is rotatable about an axis parallel to or coaxial with the operating axis (A) of the sensing element. Such rotation causes liner movement of the carrier (102) parallel to the operating axis but causing substantially no axial movement of the housing with respect to the connecting means (42). <IMAGE>
