Patent GB-953187-A (GB)
IPC: B01J27/13
Abstract: 953,187. Catalyst compositions. BRITISH PETROLEUM CO. Ltd., A. G. GOBLE, and J. N. HARESNAPE. Aug. 25, 1961 [Sept. 7, 1960; Oct. 21, 1960], Nos. 30821/60 and 36154/60. Heading B1E. [Also in Division Cl] Alumina containing surface bonded hydrogen is treated under non-reducing conditions with vapours of compounds of formula C Cl 2 XY (where X and Y which may be the same or different are H, Cl, Br, F, SCI, or where X and Y together may be S or O) without the production of free aluminium chloride. Preferred compounds are carbon tetrachloride, chloroform, methylene chloride, dichloro-difluoromethane, trichlorobromomethane, thiocarbonyltetrachloride, phosgene and thiophosgene. The alumina so treated, which may already bear catalytic components, is suitable for isomerization of C 4  and higher paraffins boiling up to 400 ‹F. The alumina may contain up to 50% of a Group II-V oxide, especially silica, titania, beryllia, zirconia and magnesium, also 0À01- 5% of a hydrogenating component in the form of a metal of Group VIA (i.e. chromium molybdenum and tungsten) or VIII (i.e. atomic members 44-46 or 76-78) of the Periodic Table, especially platinum or palladium, or compounds thereof. The preferred amount of chlorine taken up is from 1-15% by weight. Alumina hydrates in which the trihydrates predominates and those containing a major proportion of #-alumina trihydrates are especially suitable. Conveniently the alumina is prepared by hydrolysis of an aluminium alcoholate, e.g. aluminium isopropoxide in an inert hydrocarbon solvent, e.g. benzene. Inert or oxidizing conditions are employed, the latter being preferred, and carrier gases nitrogen, oxygen or air are used to contact the alumina with the chlorine compound at atmospheric pressure, and temperatures of 300 - 1100 ‹F. The addition rate of chlorine compound should not exceed 1.3 % of the weight of catalyst per minute. The catalysts are susceptible to water hydrolysis and are stored under anhydrous conditions. In Examples 1, 2, 3, 4 and 12 alumina catalyst containing platinum was treated with carbon tetrachloride at temperatures between 392-662 ‹F. using nitrogen as a carrier gas. Example 8, deionized water was added to aluminium isopropoxide in benzene, the slurry was filtered and washed yielding alumina hydrogel. After incorporation of palladium the alumina was contacted with carbon tetrachloride at 570 ‹F. Examples 6, 7 and 9 employ alumina catalyst containing platinum and chloroform in nitrogen at temperatures between 428-572 ‹ F. In Examples 5, 10 and 11 alumina catalyst containing platinum was treated with methylene chloride, trichlorobromomethane, and difluoro-dichloromethane respectively. In comparative Example 13, carbon tetrachloride was used with nitrogen but without platinum or palladium; in Examples 14 and 15, carbon tetrachloride was used under reducing conditions, and in Example 16 tetrachloroethane, 1,2 dichloroethane, tetrachloroethylene and methylene chloride were used with nitrogen giving unsatisfactory results. Specification 953,189 is referred to.

Patent GB-2303726-A (GB)
Title: Immobilization protection system for electronic products and components
Inventor: COLLINS PETER DAVID
IPC: G06F21/88
Filed: 1996-07-25
Abstract: An electronic security system embeds electronic immobilization protection devices (IPDs) in electronic products and components. IPDs have controlled access to a security service provider (SSP). At power on, and periodically there after, the IPD sends a cryptographically secure "challenge" to the SSP. If a part has not been reported stolen, then the SSP replies with a valid cryptographically secure "response", otherwise it replies with an invalid "response". If the IPD receives an invalid "response", or when a limited time has elapsed without a "response", it renders the part inoperative. A valid "response", inside the time limit, allows the part to function normally. A stolen and recovered product can be identified and traced to its rightful owner, who contacts the SSP to re-enable the product. IPDs allow specific parts to function normally for a limited period of time, so that existing hardware, software and network resources can be utilized to communicate to the SSP.

Filed: 1993-07-07
Abstract: A friction clutch with a pressure plate 403 which is connected to a housing 402 so that it cannot rotate relative to the housing but can move axially relative to the housing by a limited amount. A contact pressure plate spring 404 biases the pressure plate 3 in the direction of a clutch disc 408 which can be clamped between this pressure plate and a counter pressure plate (not shown). An adjustment device 416 is provided which automatically compensates for wear of the friction linings of the clutch disc and causes a practically constant force biasing the pressure plate 403 through the contact pressure plate spring. The adjustment device causes axial movement of a swivel support pad 412 on the housing side of the spring 404. The contact pressure plate spring 402 is supported by a supporting force whose size can change in dependence on the speed and which is directed towards the swivel pad 412 on the housing side. A plate spring 413 may provide the supporting force, the force increasing with speed due to the effort of centrifugal force acting on axially extending tongues 450 of the spring 413.

Patent GB-2315630-A (GB)
Title: General-purpose automatic focussing system
Inventor: SATO OSAMU
IPC: G02B7/28
Filed: 1997-07-21
Abstract: A focussing system 11 has three spaced and aligned sensor arrays 13A, 13B, 13C. Controller 31 controls the accumulation (integration) of charge. The system can operate in two modes, one of which is selected in accordance with whether the camera is of the single lens reflex or lens-shutter type. In the first case, each of the line sensors operates to determine the defocus repeatedly as the lens is focussed; in the latter case, only the outermost line sensors are used to determine the object distance once, and hence the amount to move the lens. This allows the use of a single, general-purpose focus system in a variety of cameras.

Title: Mapping interrupt handler routine between memories when switching between operational modes
Inventor: MOSHE DROR
IPC: G06F12/06
Filed: 1998-05-15
Abstract: A computer system (1, fig. 1) is operable in two modes of operation, for example "normal" and "sleep" modes and includes a CPU (5, fig. 1) operably coupled to first, e.g. FLASH, and second, e.g. DRAM, memory devices (6, 7, fig. 1). During initialisation, the interrupt handler routine is stored in both memories, 102, 104. During the "normal" mode of operation, and when an interrupt for switching into "sleep" mode occurs, 106, the interrupt handler routine is run from the second memory but causes the address for pointing to the interrupt handler routine to be mapped to the first memory, 108. The system is then switched to "sleep" mode, 110. When an interrupt for "wake up" arrives, 112, the interrupt handler is operated from the first memory but is re-mapped to the second memory, 114 prior to switching back to the "normal" mode, 116. Mapping the interrupt routine between the two memories obviates the need for accessing, and possibly damaging, the routine in DRAM when it is in the self-refresh (low power) mode.
