Patent GB-2471997-A (GB)
Title: Automatic transmission control
Inventor: GENTILE MARTIN
IPC: F16H59/18
Filed: 2009-07-17
Abstract: A method for operating an automatic transmission for a vehicle, comprises the steps of detecting 12 whether a target speed of the vehicle is set, calculating 18 an optimum acceleration gear in dependence of an actual virtual accelerator pedal position, and, if the optimum acceleration gear differs from a current gear, storing 26 the actual virtual accelerator pedal position, shifting 26 to the optimum acceleration gear and ignoring newly calculated actual virtual accelerator pedal positions for an acceleration period of time. Since the actual virtual accelerator pedal position is stored 26 in the case of a detected necessary gear shift and further calculated actual virtual accelerator pedal positions are ignored for a time, the operating of the transmission is based mainly on the value of the actual virtual accelerator pedal position at the time, when a necessary gear shift is detected. The risk that due to insignificant changes of the accelerator pedal position the gear is shifted up and down several times "gear hunting" until the target speed is reached is reduced.

Title: Transducer
Inventor: ELY DAVID THOMAS
IPC: G01D5/12
Filed: 2008-04-28
Abstract: A transducer is described for use in a position sensor. The transducer has a magnetic field concentrating member, such as an elongate ferrite rod, a first coil operable, in use, to couple with a first portion of the magnetic field concentrating member positioned adjacent the first coil and a second coil operable, in use, to couple with a second portion of the magnetic field concentrating member positioned adjacent the second coil, the second portion being spaced along the magnetic field concentrating member from the first portion. The transducer also comprises a resonator having a coil wound around a portion of said magnetic field concentrating member which is located between said first and second portions. The transducer is arranged so that, during use, the electromagnetic coupling between the resonator and at least one of the first and second coils varies as a function of the relative position between the elongate field concentrating member and that coil. In this way, separate processing electronics can process the signals obtained from the transducer to determine the desired position information.

Title: Fall protection for hand-held electronic devices
Inventor: CHEN WEN-YU
IPC: H02H1/00
Filed: 2009-12-02
Abstract: The hand-held electronic device 1 includes a central processing unit 12, a memory unit 13, a state-detecting unit 10, a state-determining unit 11, a main power supply unit 15, a standby power supply unit 16, and a power supply switching unit 14. If the state-detecting unit 10 detects that the device 1 is in freefall, the state-determining unit 11 will output a fall prevention instruction which causes the central processing unit 12 to store operation data in the memory 13 and to switch to the low potential standby power supply unit 16; meanwhile, the power supply switching unit 14 monitors power output and continues to supply low-potential power. In case of a fall of the hand-held electronic device 1, the device and method protect operation data and reduce the otherwise power-consuming current. The less power-consuming current is conducive to the reduction of capacitance required for a backup battery. The low-potential current mode is effective in reducing the time taken to recover the operation mode of the electronic device 1. The state-detecting unit 10 may be a gyroscope or an acceleration detector.

Title: Improvements relating to welding studs to plates and the like
IPC: B23K9/20
Filed: 1945-04-27
Abstract: 601,459. Electric welding. NELSON, T. April 27, 1945, No. 10677. [Class 83 (iv)] In welding studs to plates &c. a refractory ferrule is slidably fitted over the end of the stud and has vent slots in the end adjacent the plate to allow gases, set up during welding, to escape. The ferrule 4, Fig. 1, consists of a sleeve of refractory material such as porcelain having a bore 6 large enough to permit axial movement on the stud 2. An enlarged bore at one end forms a small chamber 7 around the stud and radial vent slots 18 are formed in this end. The stud is resiliently held by the jaws of a chuck 17 and a spring 12 is fitted over the jaws, its coils 13 engaging threads thereon at one end whilst close coils 9 lightly grip the neck 8 of the ferrule at the opposite end. In operation, the spring and ferrule are adjusted so that the ferrule is flush or “ inch proud of the end of the stud and the assembly is pressed against the work 3 ; as the stud is withdrawn to-create an arc, the spring ensures close contact of the ferrule and work. The hot gases escape through the vent slots, thus avoiding blow-out and spatter of hot metal, and producing even heat conditions. After completion of the weld, the remains of the ferrule may be left or removed by breaking with a hammer blow &c.

Title: Improvements in or relating to time-lag or delay action devices
IPC: H01H7/02
Filed: 1942-07-31
Abstract: 560,113. Automatic circuit-breakers. REYROLLE & CO., Ltd., A., and FELCE, A: July 31, 1942, No. 10735. [Class 38 (v)] [Also in Group XXXII] An automatically operated electric switch includes an electromagnetic device combined with a time - lag or delayaction device comprising two closed liquidcontaining chambers connected by a passage constituting or including a liquid-restricting device, one chamber having a flexible wall or diaphragm operable by the electromagnetic device while the other chamber is capable of accommodating additional liquid and either has a similar diaphragm or contains a body of gas so that movement of one diaphragm varies the volume of its own chamber and forces liquid through the passage from one chamber into the other chamber. As shown in Fig. 1, the chambers are formed by diaphragms C, D, and a fixed partition B in a cylindrical casing A, diaphragm C being operable by a plunger C<1> controlled by a solenoid C<2> and diaphragm D carrying an adjustable, spring-pressed plunger D<1>. The bore of the restricting passage B<1> may be varied by using interchangeable jets or nozzles or by a manually-adjustable needle valve or automatically by a valve carried by a flexible arm. The solenoid C<2> may form part of a tripping mechanism for a circuit-breaker and the current necessary to move diaphragm C can be varied by adjusting the spring D<2>. Alternatively, if the resetting time is required to be independent of the current setting, the relative position of the armature and magnet pole face may be adjusted to vary the current required to overcome the spring. If, however, a time-lag is required substantially independent of the force exerted by the electromagnet, a suitable spring may be arranged between the magnet armature and the operating diaphragm or an additional spring-loaded diaphragm may be provided in a chamber which communicates with the operating diaphragm. In a modification; the diaphragm C is adapted to force liquid through an aperture in a fixed.partition into a chamber containing air or gas, the second diaphragm being dispensed with. In another construction, Fig. 7, the opposite faces of the partition D are dish-shaped and air is enclosed between diaphragm .C and the liquid in order to give a snap-action finish to the operation of the device. The effect of cavitation is employed in the construction shown in Fig. 8, in which an operating rod J pulls the operating diaphragm J<1> away from partition B against the action of spring J<2> so that the diaphragm leaves the liquid and effects substantially instantaneous operation when the pulling force exceeds a certain value.

Abstract: 1,253,699. Laminated heater. MATSUSHITA DENKO K.K. 28 Feb., 1969 [29 Feb., 1968; 12 March, 1968; 18 April, 1968 (2); 31 May, 1968 (2); 18 June, 1968; 15 Aug., 1968], No. 10872/69. Heading B5N. [Also in Divisions H3-H5] A flexible surface heater comprises a zigzag form foil conductor 2 embedded between two heat resistant, insulating plastics films 1, 3 using a thermoplastic resin filler 4. Suitable fillers include polyethylene, polyamide, polyvinyl formal, polyurethane adhesive and nitrile rubber adhesives. The plastics films 1, 3 have similar thermal expansion coefficients to the conductor 2. Films 1, 3 are of polyamide, saturated polyester, polytrifluoroethylene, or polycarbonate, while conductor 2 is of zinc, aluminium, copper, iron, tin/lead or alloys. Manufacturing involves laminating a metallic foil 2 on a plastics film 1 using resin filler printing with anti-corrosive ink and etching to remove imprinted foil, washing, drying, application of molten resin and laminating of the other plastics film 3, Figs. 2A-2C (not shown). The thermoplastic filler, when having a negative temperature coefficient of resistance, is used for protection against excessive temperature rises of the heater, the filler 13 then allowing leakage currents to flow through it to cause opening of the circuit to resistance conductor 2 via a switch 14, Figs. 3A-3C (not shown), or an extra layer 13 of thermo-sensitive material, Figs. 4B and 4A, 4C, 4D (not shown), with melted resin layer 13<SP>1</SP> as filler, allows similar leakage current to open switch 14, Figs. 4C, 4D, (not shown), in a protective device 16 in series with a diode 20, the metal layer 18 being applied to film 13 by vacuum evaporation. The connection of the surface heater to lead wires is described, Figs. 5A, 5B (not shown). The heater may bear a design, Fig. 6A, formed by the varying widths of the parts of conductor 2, and visible through a transparent plastics sheet 25, such heaters being attached to walls or floors. Alternatively a decorative pattern is formed on film 1, Fig. 6B (not shown). Different areas of the heater may generate different amounts of heat by suitable design of conductor 2, Fig. 7, with a wider part B and a narrower width part C.
