Patent GB-2220311-A (GB)
Title: Electric toaster with electronic timer
Inventor: DENT ROBERT GEORGE
IPC: A47J37/08
Filed: 1988-06-15
Abstract: The timer controls the toasting period in accordance with the immediate previous history of use of the toaster. When a capacitor C2, connected to the threshold pin 6 of a type 555 timer T, has charged to a threshold voltage, the timer T de-energises an electromagnet EM whereupon a toast support tray rises and the heating elements are turned off. Capacitor C2 is discharged relatively slowly via a delay resistor R4 and a resistive path internal to timer T between pin 6 and ground pin 1 (rather than rapidly via the discharge pin 7) so that if a new toasting cycle is initiated closely following a preceding cycle while the toaster is still hot, capacitor C2 reaches the threshold voltage in a shorter time producing a shorter toasting period. A toasting cycle may be terminated manually by a switch SW1. In an alternative embodiment, timing capacitor C2 and an operational amplifier (IC1a), (Fig 2), provide a descending ramp voltage which is compared by a second operational amplifier (IC1b) with a reference set by a resistor chain (R5, VR1, R6) and the discharge path for capacitor C2 includes a delay resistor (R4) and that resistor chain (R5, VR1, R6). <IMAGE>

Filed: 1989-12-19
Abstract: A board game for two to four players comprises a circular track 22 divided into squares 23 and radial tracks 24 leading from start squares 23a to a central finishing zone 25. Each player has a score module 27 and a token which is moved along the tracks in accordance with throws of a pair of die and with scores on the player's module. Scores are determined by the player's responses to situation cards which define several possible feelings and thoughts in given situations or reactions to those situations and give corresponding scores. Additional scores or score variations are determined by instruction cards I, C or S which the player picks up when his token lands on a square I, C or S. An alternative game for one or two players involves the scores being recorded on a single score module on a board (51, Fig 6). The score module may also be a free- standing rocker toy or learning tool (11, Fig 3) comprising an arcuate base and three arms, the rocker being symmetrical about the central arm and capable of resting on the base on a horizontal surface in a position of stable equilibrium. The rocker is displaceable from this position by weights attachable to the arms at predetermined locations. <IMAGE>

Patent GB-2246417-A (GB)
Title: Built-in valve-locking mechanism
Inventor: LAM KIM SONG
IPC: F16K35/06
Filed: 1990-06-05
Abstract: A locking mechanism built inside a valve is operated, when the valve is closed, by an indexing pin key (1) which has a set of pins on it. Once inserted into the hand knob (14), the pins on the key frees a rotatable plug (2) from spring biassed tumblers (3). When the plug is turned via the key, the cam pin (7) at its end slides home a latch bolt (8) into a slot in the fixed head (g). This jams the rotation of spindle (11) thus locking the valve (12). To unlock, turn the indexing pin key (1) anti-clockwise so that the latch bolt (8) fully retracts into the spindle (11) thus freeing it once more. This mechanism does not affect the normal operations of the ON/OFF regulation of the flow. <IMAGE>
Patent GB-901785-A (GB)
Abstract: 901,785. Automatic voltage-control systems. MASCHINENFABRIK OERLIKON. Sept. 7, 1959 [Sept. 12, 1958], No. 30516/59. Class 38 (4). An A.C. voltage error detector consists of two opposed circuits, one responsive to changes in both amplitude and frequency, the other responsive only to frequency changes so that frequency errors are eliminated. In one embodiment, Fig. 1, the output of a saturable transformer 2, which is independent of changes in the amplitude of the A.C. voltage U but varies with frequency changes, is rectified at 5 and compared with the output of a rectifier 14. Rectifier 14 is energized in accordance with the voltage across a linear impedance 15. Impedance 15 is in series with a resistor 16, the value of which is large relative to the reactance of impedance 15, the voltage across which, therefore, varies with both frequency and amplitude. The opposed D.C. voltages are applied to an unspecified regulator 10. In a modification, Fig. 2 (not shown), the rectifier 14 may be energized, by a 3-phase connection. In a second embodiment, Figs. 6 and 7 (not shown), the rectified output current of the saturable transformer is compared with the output current of the rectifier 14. A third rectifier 18 maintains the reference voltage in the event of a failure of the source U. To reduce the losses in resistor 16, the reactance of impedance 15 is effectively reduced either by shunting impedance 15 and part of resistor 16 with a capacitor 17, or by connecting the parallel combination of an impedance 3 and variable resistor 4 between the saturable transformer 2 and the rectifier 5.

Title: Process for producing surface-treated steel sheet superior in weldability and paint-adhesion
Inventor: KANEDA YOSHIHIRO
IPC: C25D11/38
Filed: 1992-01-23
Abstract: In the surface treatment, firstly, the surface of a steel sheet is subjected to tin-plating in an acidic tin plating bath containing a conventionally used brightener in an amount of from 0.001 to 0.05 g/l so as to form flattened granular tin coating deposits having a diameter of 0.4 - 2.4  mu  at a plated area ratio of 5 to 30% and to improve the adhesion to the steel sheet and decrease falling-off of the granular tin coating deposits until completion of chrome-plating, thereby the variation of the amount of tin coating being decreased, and subsequently, the sheet is plated with metallic chromium in an amount of 50 - 150 mg/m<2>, and further chromium hydrate oxide layer is formed in an amount of 2 - 40 mg/m<2> as chromium. Thus a surface-treated steel sheet suitable for food/beverage containers, which has satisfactory surface appearance, paint adhesiveness, under-paint-coating corrosion resistance of conventional tin-free steel sheets, and stable weldability, is producible at a low cost.
