Abstract: A method and apparatus for simulating the operation of a rechargeable battery. A value is obtained for at least one parameter that describes an internal state of the battery. The obtained value is used for calculating a prediction value for a characteristic of the battery that is observable outside the battery. These steps are repeated a multitude of times in order to simulate the operation of the battery over a certain period of time. A difference is detected between a calculated prediction value and a known value of a corresponding characteristic in a corresponding situation. The obtained value of the at least one parameter is corrected before a further prediction value is calculated by an amount that is proportional to the detected difference.

A spray gun comprises a pump piston 44 drawing coating material from a surge chamber 31, connected at 30 to a source of material under air pressure, through spring loaded valve controlled passages 34 and delivering through valve controlled passages 50 to a nozzle 54. The quantity discharged is controlled by a manually set throttle valve 62 connecting the pump chamber to the inlet passages 34. The piston 44 is connected to pistons 72, 74, the piston 72 being subjected to constant air pressure while the opposed side of the piston 74 is alternately connected to the air pressure supply under the control of a trigger activated valve which controls the supply to a passage 80 and a chamber 82 connected through passage 84 to an annuler chamber 86. A valve 88, seating in one position on the end 92 of the motor cylinder and in another, on an annuler seat 90, controls the connection between the chamber 86 and the motor cylinder and between parts 112 in the cylinder and an exhaust outlet 115; the valve is subjected to constant air pressure via a pipe 110. On forward movement of the piston 74 the ring 76 uncovers an exhaust part 94 and air is trapped behind the piston which assists return by pressure acting of the piston 72. Collapse of pressure in the motor cylinder causes valve 88 to seat on the end 92 and the parts 112 are connected to exhaust 115. On return of the piston 74 the parts 112 are closed by the ring 76 so that pressure builds up in the cylinder to lift the valve 88 from the seat 92. A bleed 116 is provided to ensure that the valve 88 lifts from seat 92 for starting purposes.

Abstract: 1,053,634. Programmed control of welding. INSTITUTE ELEKTROSVARKI "E. O. PATON. " Feb. 10, 1964, No. 5522/64. Heading G3N. In a resistance butt-welding operation, employing a burning-off method, the welding parameters are automatically controlled during successive periods of the operation by a programming device. As shown, clamping jaws 2 carrying one workpiece 3 move slowly towards stationary clamping jaws 1 carrying a second workpiece 3. Burning- off begins with initial contact between the electrodes and the current in a primary 5 of a welding transformer, supplying the jaws 1, 2, rises as the roughness is removed from the faces of the workpieces. The rising current is sensed by a transformer 8 and through a measuring device 9 is applied to a programme triggering unit 10, comprising a capacitor and transistor integrating combination, which measures the integral current magnitude and transmits a start signal to the input of the timer 11 which starts counting a first welding period of the programme during which the welding periods are maintained constant. At the end of the first welding period a voltage regulator 7, comprising controlled ignitrons, is brought in through a programming unit 14. Simultaneously a signal is sent to start a relay 12 which times the second period. During the second period the rate of movement of jaws 2 is maintained. At the end of the second period the relay 12 transmits a signal to a velocity programming unit 16, controlling a speed regulator 18 for the movable jaws 2, for a predetermined increase in the displacement rate prior to the operation of a process multi-circuit time delay relay 13 controlling the third period, upsetting through a drive 19, and the fourth period at the end of which the timer 11 and relay 12 are reset. The voltage programming unit 14 and velocity programming unit 15 operate on the change in the internal resistance of a triode with discharge of a capacitor in a control circuit. The welding programme is set up on a reader 17 wherein a double-sided system of spring contacts are separated by a stationary card having apertures therein. The contacts are connected with the core corresponding units of the system, the apertures determining the settings for the welding parameter.

Abstract: 1,225,763. Measuring stress relaxation; measuring stress relaxation electrically. MINISTER OF TECHNOLOGY. June 19, 1968 [March 20, 1967; Jan.16, 1968], Nos.12957/67 and 2268/68. Headings G1N and G1S. An instrument for measuring the stress relaxation of a material comprises means for loading a test piece 4 on the instrument to produce a given deformation of the test piece and means for measuring the reaction of the test piece on the loading means continuously or after a given time. The loading means comprises a rigid anvil 2 fixed to a base 1, a clamp 3 for securing the centre of the specimen to the anvil and loading prongs 9 attached to a ballistic pendulum 7 suspended by four cords 8. When an electromagnet 10 is energized by closing a switch 17, the core 10a attracts an iron armature 11 attached to the pendulum so that the prongs 9 bend the test piece against the anvil. The switch 17 also actuates a timer 16 which, after a pre-set time, de-energizes the electromagnet thereby allowing the pendulum to swing back. The restoring force, the magnitude of which due to the stress relaxation effect decreases as the time for which the test piece is clamped is increased, is measured by any of the following methods: a) A plunger 12 is fixed to the pendulum and has an iron core 12a which moves in a differential transformer connected to a recorder 14. The position of the core when the test piece is clamped and the position of the core corresponding to the maximum amplitude of the swing of the pendulum when the clamping is released are recorded. The measurement of these positions enables the restoring force to be calculated. b) A fine cord 21 passing through a glass guide tube 22 is attached by a bracket 7a to the pendulum and the two previously mentioned positions are measured by noting the change in position of a mark on the cord against a scale. c) A load cell 18 is connected to a recorder 19 and/or an indicating instrument 20 for continuously measuring the reaction of the test piece. The anvil may be enclosed in an oven for tests at various temperatures and the instrument may be used for test pieces in the form of discs, rings or pipes as well as beams. The instrument may be used for testing metals or elastic non-metals and is particularly suitable for testing plastics materials.

Abstract: 1,228,115. Insect traps. U.S. AGRILITE Inc. 2 Dec., 1969 [2 Dec., 1968], No. 58885/69. Heading A1M. [Also in Divisions A5 and C2] Traps for pink bollworm moths consist of plastic cups fitted with a wire or string across the top diameter to which are attached several folds of absorbent paper impregnated with the attractant compound cis-7-hexadecen- 1-ol acetate (see Division C2 for preparation). The attractant compound may be mixed with adhesive materials such as used to coat fly paper or may be used in conjunction with maze traps, funnel traps, electric light traps, electrocution grids or sterilizing gamma-ray sources.
