Title: Policy enforcement in trusted platforms using external policy engines
Inventor: PROUDLER GRAEME JOHN
IPC: G06F21/57
Filed: 2008-10-31
Abstract: A trusted entity 90 in a trusted computing platform comprises an input for receiving a trusted operation request from a requesting application 96 (e.g. a request to release a secret key), a trusted process for generating a challenge for at least one external policy engine 98 that is identified for authorising the request, the challenge including an authorisation value (e.g. a random number), and an output for delivering the challenge to the identified policy engine. The policy engine and the requesting application interact to enforce the policy, e.g. by authenticating the requesting application and any user controlling the requesting application, and the policy engine then passes the authorisation value to the requesting application which in turn communicates it to the trusted entity. The trusted entity compares the received authorization value with its copy and performs the requested operation if there is a match. The invention enables a trusted entity to delegate responsibility for enforcing policies to external policy engines, i.e. policy engines outside of a trusted entity, either on the same trusted platform or on a remote platform. Thus, even more complex policies can be performed without significant additional resources being required within a trusted entity. The invention can be used for migrating a Certified Migratable Key (CMK) from one trusted entity to another.

Title: Fuel consumption controller
Inventor: MCALORUM JAMES
IPC: F23N1/00
Filed: 2009-10-14
Abstract: A fuel consumption controller, especially for an oil or gas fired domestic heating burner, wherein the amount of fuel burnt in a time period is estimated using the time the burner has been firing and the flow rate specification of a fuel nozzle 9 which delivers fuel to the burner 3, the operation of the burner is limited for the remainder of the time period if the estimated fuel consumption exceeds a volume limit. Preferably the burner is operated by a control waveform, such as a series of pulses each of which represents a fixed volume of fuel, and therefore the duration of the pulses depends on the flow rate specification of the fuel nozzle. The comparison between the estimated fuel use and the volume limit may be worked by counting down the number of pulses allowed within the time period.

Title: A device for producing a series of electric pulses
IPC: H03K3/26
Filed: 1959-03-24
Abstract: 847,458. Pulse modulation circuits; transistor oscillator circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. March 24, 1959 [March 26, 1958], No. 10108/59. Classes 40(5) and 40(6). Relates to pulse modulation devices, particularly for remote metering purposes, in which the duration of each pulse is proportional to one direct voltage and the interval between pulses is proportional to another or the same direct voltage. The circuit shown comprises two capacitors 1, 2, connected to a direct voltage source 5 through resistors 3, 4, and two pairs of input terminals 7, 9 to which the input voltages E 1 , E 2  are applied. Assuming capacitor 1 to be under charge, part of the charging current flows through resistor 24 to terminal 26, and the remainder flows through transistor 10, point 20 being at zero potential. Hence diode 12 conducts and capacitor 2 is short-circuited by diode 12 and transistor 10. No charging current flows through transistor 11 and point 21 is held at the potential of terminal 16 i.e. -26 volts, diode 13 being cut off. The charging current through transistor 10 flows through relay coil 17<SP>1</SP>, switch 17a is closed and a direct voltage is applied to output conductor 29. The voltage across capacitor 1 increases linearly until it equals E 1  at which point diode 6 conducts and most of the charging current is taken by capacitor 27 so that transistor 10 is cut-off. Point 20 assumes the potential -26 volts, diode 12 is cut off and charging of capacitor 2 commences. Capacitor 1 is short-circuited by diode 13 and transistor 11, and the charging current through relayc oil 17<SP>11</SP> opens switch 17a. Capacitor 2 is charged linearly until the voltage across it equals E 2  whereupon the charging process switches over to capacitor 1 and switch 17a is again closed. If the same voltage is applied to both pairs of input terminals 7, 9 the period of the pulse series produced is proportional to the voltage applied. The output pulse train may be derived from the voltage developed across either of resistors 18, 19.

Abstract: 649,151. Wave-guides. RADIO CORPORATION OF AMERICA.. April 12, 1948, No. 10123. Convention date, May 14, 1947. [Class 40 (viii)] [Also in Group XL (c)] A wave-guide system comprises a main guide connecting a source to a load and having increasing transverse dimensions from source to load and branch guides each connecting a source of lower frequency to the main guide at points at which its dimensions become large enough to transmit the lower frequencies. Energy of wavelength #A is fed to a tapered wave-guide 5 from a source A at the smaller end of width a. Energy of wavelengths #B, #C is fed to the guide 5 by branch guides 3, 4 of width b, c respectively. The branch guides are so positioned that energy from each source is only propagated along the main guide away from source A. The branch guide 3 is provided with a filter stub 26 comprising a section of width a and length adjusted to prevent energy of wavelength #A entering the guide 3, and a section of width b and length adjusted to reduce the effect of the discontinuities in the branch guide. The branch guide 4 is provided a filter and matching stub 15 similar to stub 26 but adjusted to prevent energy of wavelength #B entering the branch, and a second filter stub 16 comprising three sections of width a to prevent energy of wavelength #A entering the guide. The three sections may be so adjusted that side bands are also excluded. Branch guide 4 may also have a third stub similar to stub 16. The main guide may comprise rectangular sections of uniform dimensions connected by pyramidal sections, and the branch guides may be bent through 90 degrees at their junctions with the main guide.

Title: Potentiometers and adjustments thereto
Inventor: GALL DOUGLAS CRISP
IPC: H01C17/235
Filed: 1968-03-01
Abstract: 1,235,871. Machine tool details; making potentiometer windings; rotary filing. H. TINSLEY & CO. Ltd. 5 May, 1969 [1 March, 1968], No. 10150/68. Headings B3A, B3B and B3K. [Also in Division H1] A method of adjusting a potentiometer wire so that all its parts have equal resistances involves comparing each part in turn with a standard resistance (by means of a potentiometer circuit and galvanometer), and reducing (by filing) the cross-sectional area of a length of each part until the resistance of each part equals the standard resistance. The standard resistance is made equal to that of the part with highest resistance. The potentiometer wire 12 is supported between formers 14, 15 on a turntable 17. A file 21 is driven by a rotary motor 22 on a slide-plate 23 attached by lever 35 to a crank-wheel 33. A further motor 32 is caused to rotate the wheel 33 through one revolution when the resistance of a part 13 equals that of the standard resistance, so that the slide plate 23 and file 21 are moved away from and then towards the wire whilst a connection of pushrods and levers 45, 48, 52, 53, 55 leading to a ratchet mechanism (Fig. 2, not shown) causes the turntable to be advanced by one loop of the wire. A rocker motor 37 driving a rocker cam 38 causes slide arms 24 to pivot about axis 28 and thus raises and lowers the file 21. The shaft 35 is connected to the slide-plate 23 via a compression spring (71, Fig. 3, not shown). Switches and connections to the galvanometer are included (75, 76, 77, 65, 66, 78, 80, 81).
