Abstract: 270,629. Ereky, C. May 7, 1926, [Convention date]. Medicinal preparations; extracts, making.-In the manufacture of medicines for human beings, green fodder, including all green plants or plant waste, vegetables, and medicinal herbs, is subjected to a cutting-up process which disrupts the cells. The process may be carried out in a stream of liquid, which may be the thin pulp derived from a previous operation. This thin pulp is protected from decay by formaldehyde or sulphurous acid. The pulp so obtained may be divided into two parts, one containing the cell juice, which is rich in plasma, the other containing the cell-wall residues. The pulp, or the cell juice, may be treated by cooling, or by disinfectants, or both, and may be stored. The Specification as open to inspection under Sect. 91 (3) (a) states also that the water may be extracted at a low temperature and reduced pressure, disinfectants, e.g. formaldehyde or sulphurous acid, being added. The cell-wall residues may also be dried and stored. The pulp or cell juice may also be kneaded with the pulverized dry product of a previous operation, or with flour, starch, &c., or other powdered substance, and formed into plates &c. and dried. This subject-matter does not appear in the Specification as accepted.
Patent GB-518102-A (GB)
Title: Improvements in or relating to alternating current electric switches
IPC: H01H9/56
Filed: 1938-08-15
Abstract: 518,102. Arc-rupturing in switches. PATENTVERWERTUNGS-GES. HERMES. Aug. 15, 1938, No. 24049. Convention date, Aug. 13, 1937. [Class 38 (v)] In an A.C. switch with multiple micro-gaps for spark-quenching, the control and separating movement of the individual contact member are effected synchronously with the phase-position of the current, thereby enabling high-current circuits to be opened satisfactorily in the neighbourhood of the'current-zero and avoiding the arc-like flashover which occurs in micro-gap switches when interrupting currents above a certain value and cannot be extinguished. Contacts of good heat conductivity are employed for the gaps. In Fig. 1, when the blade 12 is opened at the desired instant on overload, the current or a component thereof is shunted through an electromagnet 7, which co-operates with an armature 6 on a spring or pivoted blade 4 to increase the pressure between a number of contacts 3 and cooperating fixed contacts 1 forming the seriesconnected breaks. At the same time a directcurrent magnet 8 is excited,'and when the current in 7 approaches zero the force exerted by 8 on the armature 6 predominates, so that 3 are separated from 1 to the extent of a fraction of a millimetre. Pressure gas (air or nitrogen) or other insulating medium, as oil, may be admitted to casing 2 through the pipe 14 in order to reduce the number of gaps, and the potential drops across the several breaks are equalized by capacity and/or resistance or auxiliary potentials. The Specification refers also to a spring or permanent magnet in place of the electromagnet 8, and to the arrangement of the micro-gap switches around the periphery of a circular member. The synchronous control could be effected, alternatively, in the manner described in Specification 422,775. The switch may be combined with one or more choking coils which are saturated at currents within the limit of values suitable for arc-quenching, and can then be combined with some of the arrangements disclosed in Specifications 490,509, 492,639, and 493,436, the choke being inserted in circuit at the moment of opening the blade 12. In Fig. 2, the blade 18 is in series with the contacts 1, 3 and carries a projection 23 which, in the closed position, bears on a spring 22 which is connected by a pin 21 passing through the support of contact 1 and packed or soldered in a diaphragm closing the bottom of the container 2, so as to maintain the armature 6 against the electromagnet 7. When 18 is moved slightly in the opening direction, while still engaging 19, the spring 22 comes into play and at a predetermined current-value overcomes the magnet 7 and the electrodynamic attraction of the currentloop formed by the contact supports, and opens the contacts 1, 3. Thereafter the blade 18 is fully separated. The invention is also stated to be applicable to rectifiers, inverters and frequency changers employing a synchronously oscillating or rotating arrangement, such as a synchronous motor

Abstract: 651,939. Cable joints. PIRELLI-GENERAL CABLE WORKS, Ltd. Sept. 14, 1948, No. 24074. Convention date, June 11, 1940. [Class 38 (i)] [Also in Group XXII] In an oil-filled electric cable, a method of joining two hollow conductors by a soldering operation is provided, while a flow of oil is maintained through one or both conductors in which the flow of oil is diverted from passage through the point of junction during soldering. In an embodiment, Fig. 1, conductors 1, 1<SP>1</SP> formed by a single layer of wire have passage 4, 41 made therein by bending some of the wires towards the conductor axis to allow oil supplied by reservoirs at the remote ends of the conductors 1, 1<SP>1</SP> to flow from the conductors 1, 1<SP>1</SP> as indicated at 5, 5<SP>1</SP>. Solid core 6, 61 of aluminium if the conductors 1, 11 are of aluminium, are placed in the conductor ends and metal rings 7, 7<SP>1</SP> are compressed on the wires around the cores 6, 6<SP>1</SP> to prevent oil flow along the wires. A mould is placed about the wires at the junction point 8, into which molten aluminium is poured to effect the soldering of the conductors 1, 1<SP>1</SP> and cores 6, 6<SP>1</SP>. When soldering is complete an electrostatic screen is placed around the conductors 1, 1<SP>1</SP> so that oil flows from the passage 4 through the screen to the passage 4<SP>1</SP> to maintain oil flow through the cable. In a modification in which the conductor is formed of two wire layers, some wires are bent towards the axis and some away from it to provide the byepass passage. In a further embodiment in which a cable end is connected to a terminal, the conductor 19, Fig. 4, is provided with a passage 25 and an iron core 27 having a lateral hole 28 and a closing diaphragm 33 is entered into the conductor 19 while a ring 29 is compressed on the wires about the core 27. A sleeve 22 is placed over the core 27 so that a hole 23 therein corresponds with the hole 23 and soldering with molten aluminium at 30 takes place when the conductors are of aluminium. When soldering is complete and the passage 25 is closed by insulation 34 a bell 31 connected to an insulator 32 is placed about the conductors and the diaphragm 33 is punctured to establish communication between the hollow cable and the terminal chamber. If the conductor is made of strips, passages are formed by mating holes in one or more strips.
