Patent GB-1259087-A (GB)
IPC: H02P23/24
Filed: 1970-02-20
Abstract: 1,259,087. Control of A.C. motors. CHARLES MAIER & CO. 20 Feb., 1970 [5 March, 1969], No. 8174/70. Heading H2J. A three-phase motor is supplied through reversing contactors P2, P3, and a triac is connected in each of the three supply lines, an additional relay P1 having contacts for transmitting switching signals to the triacs. The motor is reversed by blocking the triacs by de-energizing relay P1, de-energizing contactor P2, energizing contactor P3, and firing the triacs by energizing the relay P1. Each step in this operation is divided by a timing interval. When contacts 11, 12 are closed, transistors T1, T2 are conductive so that relays P1, P2 are energized. Opening of the contacts 11, 12 discharges capacitor C1 abruptly through diode D1 and transistor Tl so that the relay P1 is de-energized quickly. Capacitor C2 is discharged through diode D5, relay P2, and transistor T2, the relay P2 being de-energized after the relay P1. When contacts 11, 13 are closed, capacitor C3 does not commence to charge as long as there is voltage across capacitor C2, this voltage causing transistor T6 to conduct and bridge the capacitor C3. After capacitor C2 has discharged, capacitor C3 charges slowly until trigger diode D3 breaks down to render transistor T3 conductive whereby relay P3 is energized. Transistor T4 is rendered non-conducting when transistor T3 starts to conduct so that capacitor C1 is charged through resistor R1. Transistor Tl conducts after a time delay whereby the relay P1 is energized. The switching sequence back to the original direction of rotation is similar. In a modification, the capacitors C2, C3 are associated with monostable trigger circuits which act as threshold devices, Fig. 3 (not shown). If contacts 11, 13 close before contacts 11, 12 open, transistor T4 conducts to deenergize relay P1.

Abstract: 1,259,356. Valves. I.F.R. CROOK. 16 July, 1970 [16 April, 1969], No. 19463/69. Heading F2V. [Also in Division H1] An operating member 1, Fig. 5, for an electric switch or fluid valve comprises a rockable element supported at at least one end by a resilient diaphragm 4 whereby the member has two alternative stable positions. In the example the member 1 is pivoted on a ridge 13 of the base 14 which may be an integrally moulded flexible hinge. In another example the actuator 22, Fig. 9, is mounted on an integral flexible hinge 25 and has a flexible diaphragm 23 at one end only, and which extends peripherally along the rounded end and sides of the actuator 22 so that the diaphragm is of a generally crescent form. A rigid extension 26 of the actuator may extend upwardly above the face of the face plate 24 when the actuator 22 is depressed so that it may be restored to the initial position (shown) by depression of the extension 26. In a modification a rigid actuator 30, Fig. 11, has a downwardly extending web 31 with triangular shaped flexible diaphragm ends 33 integral with fixed ribs 32 whereby two alternative stable positions are also obtained.

Inventor: HAAMER JOEL
IPC: A23L17/50
Filed: 1999-06-14
Abstract: The invention relates to a method and a device for cooking and vacuum packing mussels with their shell and other foodstuffs by microwave heating so that they can be stored as chilled or frozen goods for an extended period. When mussels are vacuum packed, many of the shells often break, and moreover the subsequent cooking in water is too slow for the mussel meat to coagulate satisfactorily. The invention solves this problem by packing the product to be preserved, in the first place mussels, in a somewhat flexible plastic container which is sealed. On the top side of the container there is a venting hole which permits the escape of steam during boiling but which is sealed immediately as microwave heating ceases, whereupon a vacuum arises inside the container as the steam condenses. A vacuum packed and pasturized product is thus obtained in one and the same operation.
