Patent GB-2254914-A (GB)
Title: Automobile heater
Inventor: HIGASHIHARA AKIHITO
IPC: B60H1/08
Filed: 1992-03-16
Abstract: The amount of high temperature engine cooling water supplied to heater core 21 and the amount of low temperature cooling water from the heater core 21 passed through return passageway 46 are controlled by an on-off manner control of first and second valves 25a and 25b, respectively, and thus a ratio of a mixture of the high temperature water and the low temperature water, which corresponds to a time average value of the temperature of the cooling water introduced into the heater core, is controlled in accordance with a duty ratio of the on-off signals operating the valves 25a and 25b. This on-off control of the valves 25a and 25b prevents deposition of impurities between the valves and valve seats. The frequency of the on-off cycle can be reduced, to prolong the service life of the device. A by-pass passageway 47 is provided for preventing water hammer. <IMAGE>

Patent GB-2262430-A (GB)
Title: Improvements relating to packaging of potatoes
Inventor: WOOTTON RONALD MICHAEL
IPC: B65B25/04
Filed: 1992-11-24
Abstract: A potato (19) is sealed into a pack (18) formed from sheet material so as to enclose atmospheric air or a comparable oxygen-containing gas. The sheet material is impermeable to the gas or semi-permeable to oxygen. The initial oxygen volume is between 4% and 12% of the volume of the potato. This control of the atmosphere within the pack ensures that the rate at which greening or sprouting occurs is kept low and in addition the creation of conditions which might lead to rapid decay are avoided.

Title: Tranformerless modem
Inventor: YOUNG STEVEN JAY
IPC: H03K17/795

Title: High speed access control
Inventor: AKIZAWA MITSURU
IPC: G06F13/42
Filed: 1993-02-24
Abstract: In a computer system having an interface with an I/O bus 160 given disconnect/reconnect functions and a plurality of magnetic disk subsystems 170-0 to 170-3 connected with the I/O bus, control divides a file at a disk access time with reference to disk management information, file management information and file descriptor translation information to read/ write a plurality of such files asynchronously. Thus, high speed file access can be realized by only the plurality of magnetic disk subsystems without requiring any special control hardware. A corresponding relation between subfiles in a virtual directory and the application request file can be taken to construct the directory, thus making the divided storage transparent to the application. <IMAGE>
Patent GB-2276011-A (GB)
Title: Power meters
Inventor: PAYNE KENNETH
IPC: G01R19/252
Filed: 1993-03-13
Abstract: An apparatus for measuring electrical power is adapted to produce an output signal proportional to the product of a supply voltage and current flowing through a load connected thereto. A first signal proportional to the supply voltage and a second signal proportional to the load current are used to modulate the period of two constant frequency carrier signals. At least the voltage modulated signal is averaged by signal processing means 13 - 19 to provide a zero reference value for the apparatus. Multiplication at 26 of the modulated signals by the microprocessor produces the power product output signal. Successive values of the period-modulated voltage-related signal are accumulated. The accumulated value is periodically latched and fed to a computer. A pulse counter and timer may be provided to receive and measure the voltage-related period varying-signal. <IMAGE>

Patent GB-2307123-A (GB)
Title: Phase-frequency tracking apparatus
Inventor: HULBERT ANTHONY PETER
IPC: H03D3/00
Filed: 1995-11-07
Abstract: The phase-frequency tracking apparatus comprises a phase detector including frequency discriminator 2 and an accumulator 6,8. The frequency discriminator receives complex base band inphase and quadrature phase signals, which are also received by a mathematical argument function module 4. The output of the frequency discriminator is passed via an adder 6 and a multiplier 10 to a further adder 14. The adder 6 at a further input receives the output signal from the further adder 14 which is fed back via a shift circuit 8. The output of the module 4 is passed via a multiplier 12 to a further input of a further adder 14. The output of the adder 14 which represents the extended phase output is switched between the output of the frequency discriminator 2 and the output of the module 4. This is achieved by a controlling signal which is applied to a further input of the multipliers 10, 12, and is generated from a digital recursive filter 16, 18, 20, 22. The output of the filter * small Greek alpha * is scaled by circuit 24 to produce an output * small Greek beta * which is passed via a circuit 26 which generates the controlling signal * small Greek gamma * ensuring that the signal * small Greek beta * is always positive. The frequency discriminator may be of the type disclosed at figure 2 (not shown).

Inventor: BARBUR VICKI ANN
IPC: G05B19/418
Filed: 1996-02-03
Abstract: The product has specified performance characteristics, and is manufactured using a plurality of constituents. A set of properties of the constituents which affect the product performance characteristics is defined, sampling data on the set is determined, and a model is defined using the sampled data in terms of parameters T 2 and Q res where T 2 is derived from the sum of the squares of each of the principal components of the model, and Q res is derived from a weighted sum of squares of principal components not included in the model. The derived T 2 value is compared with a standard for that product and, if the value of T 2 exceeds a predetermined limit, there is an indication that there has been a significant change in the typical properties of the constituents. The relevant constituent and property can be determined, and action can be taken to replace defaulting constituents prior to manufacturing.
