Title: Ringing arrangement for telephone systems
IPC: H04J1/14
Filed: 1926-02-17
Abstract: 270,825. Standard Telephones &. Cables, Ltd., (Western Electric Co., Inc.). Feb. 17, 1926. Wired wireless systems; calling systems. - In a transmission line connected to outgoing and incoming branch circuits in conjugate relation by means of a hybrid coil, provision is made for sending and receiving ringing calls diagonally through the hybrid coil without unbalancing the associated circuits. An outgoing ringing-signal impressed upon the line L energizes a relay 6 which in turn operates relays 7 and 8. Relay 7 disconnects the line L from the hybrid coil H. Relay 8 disconnects conductor 14 from the lefthand terminal of coil H, and allows a 20-cycle ringing current from a generator G to pass through the upper left-hand winding of coil H to the modulator M and thence to the outgoing line, the return circuit being made through the lower right-handing winding of coil H and contact of relay 8. Simultaneously, relay 10 disconnects the balancing network N from the hybrid coil, whilst relay 12 disconnects the receiving apparatus 17, 18, for incoming calls from the conductors 14. Incoming call signals after passing through demodulator DA are impressed on the coil H and are selectively transmitted through a tuned circuit 17 to the input of a detector 18. The output from the latter actuates first relay 19 and then relay 20, which in turn short-circuits relay 21 and so establishes an operating circuit for relay 15. Relay 15 introduces a 20-cycle ringing source into the line L, and simultaneously energizes relays 7 and 10 to disconnect the hybrid coil H and the balancing network N.

Title: Improvements relating to the production of fat-soluble vitamin concentrates
IPC: A61K31/59
Filed: 1948-02-17
Abstract: Vitamin concentrates are obtained from oleaginous vitamin-containing materials by saponifying, e.g. with potassium hydroxide, the oleaginous material to form a soap mass, extracting the soap mass with a hydrocarbon or halogenated hydrocarbon, e.g. ethylene di-chloride, or a mixture of such solvents while maintaining the temperature of the solvent and the soap between about 40 DEG  C. and just below the boiling point of the solvent, and separating the warm solvent from the warm soap, the process being characterized in that the water content of the soap during the extraction is maintained at such an amount that the soap is slightly soluble in the solvent, i.e. the soap is less than 1 per cent soluble in the solvent.  As starting materials there may be used substances of marine origin, e.g. fish liver oils.  Detailed examples are given.  Specification 550,845 is referred to.

Title: Improvements in pump operated central heating systems
IPC: F24D19/10
Filed: 1969-01-29
Abstract: 1,236,834. Water heaters. JUNKERS & CO. G.m.b.H. 29 Jan., 1969 [2 Feb., 1968], No. 4903/69. Heading F4A. In a pump-operated central heating system of the kind having a boiler which serves as a heat source selectively for the central heating system or for a domestic water heater, the water circulation being directed either to the heating elements of the central heating system or to the domestic water heater by means of a three-way valve controlled by a thermostat whose temperature senser is arranged in the water space of a domestic water reservoir serving as the domestic water heater, the reservoir is an independent unit, and the three-way valve and thermostat are arranged solely on the unit. This facilitates the addition of a domestic water heater to an existing central heating system. The central heating system shown comprises a gas-fired boiler 10 supplying radiators 16, the circulating pump 23 being located in the main return line 22. Domestic hot water is supplied from a unit 11 comprising a hot water tank 45, circulating flow being diverted from the radiators 16 to a calorifier 18 by a three-way valve 14 under the control of a priority switch 38 and a thermostat 34 comprising a temperature senser 35 and a switch 36. The priority switch 38 causes the gas flow regulator 42 to operate at a higher level when the circulating water is flowing through the calorifier 18 instead of the radiators 16. If the temperature of the circulating water exceeds a predetermined value, a switch 44 of a thermostat 43 renders the boiler 10 inoperative. The three-way valve 14 and the thermostats 34, 43 are arranged on the housing 47 of the hot water tank 45 so that the domestic hot water unit 11 is separate from the boiler 10, the valve and thermostats preferably being mounted on a wall of the housing, facing the boiler. A hard foam insulation 48 is provided. An adjustable by-pass valve 26 can be provided to afford a minimum flow of circulating water for controlling a water-deficiency safety device. The boiler 10 is provided with a thermostatically controlled by-pass valve 25. The unit 11 may be inverted, the long cold water inlet pipe 29 and the short hot water outlet pipe 30 then being interchanged. There may be more than one domestic hot water tank, connected either in parallel or in series with each other.

Abstract: 691,636. Glass manufacture. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., PARTRIDGE, J. H., and SIMMS, C. H. Feb. 29, 1952 [March 1, 1951], No. 5003/51. Class 56. [Also in Group XL (a)] In manufacturing a glass envelope for a cathode-ray tube of the type comprising three portions sealed together, namely a dished plate end section, a central section of approximately truncated conical form and a cylindrical section housing the electrode assembly the central section 1 is pressed with a closed narrower end terminating in a short cylindrical stub 2 which is at least partly hollow inside. The stub and adjacent end of the section 1 is subsequently softened by heating, the stub 2 is cut at its hollow part, and into the opening thus formed is placed an internal roller 5 shaped at 6 which rotates about a spindle 8 mounted on block 7. A co-operating shaped roller 9 rotating about spindle 11 on block 10 is brought against the external surface of the stub and adjacent part of section 1, the rollers being squeezed together whilst the conical section 1 is rotated about its axis, the internal and external surfaces of the stub and adjacent part of the section 1 thus being tooled to the requisite dimensions, and the stub elongated to form a cylindrical tube having considerably thinner walls than the remainder of the conical section. The length of the tubular stub 2 is controlled by a third roller 13 rotating about a horizontal spindle 14 in the block 10 or the roller 13 is omitted and the stub subsequently cut to size. The cylindrical, electrode containing, section is of similar diameter and wall thickness to the elongated stub 2 to which it is secured. In a modification, the rollers 5, 9, are in relatively rotatable sections for matching the different peripheral speeds of the different parts of the glass against which they abut.
