Title: A-b-s polyblend
IPC: C08L51/04
Filed: 1968-10-23
Abstract: A polyblend comprises (A) a matrix of an interpolymer consisting of at least 50% by weight of a monovinylidene aromatic compound and an unsaturated nitrile, (B) a first graft copolymer having a rubber substrate and a superstrate of an interpolymer of the type specified under (A), said first graft copolymer being highly cross-linked with a swelling index of less than 15, and (C) a second graft copolymer of the type specified under (B), said second graft copolymer being relatively lowly cross-linked with a swelling index of not less than 20, said first and second graft copolymers together constituting 1 to 70% by weight of said polyblend and said first graft copolymer constituting from 60 to 95% by weight of the combined weight of the graft copolymers. The polyblend is prepared by blending separately prepared graft copolymers and additional matrix interpolymer, when required, or by grafting a mixture of two rubbers having different degrees of cross-linking. In the examples, styrene-acrylonitrile interpolymer is blended with (1) a graft copolymer of styrene and acrylonitrile on butadiene-styrene rubber which has been cross-linked with divinyl benzene and a similar graft copolymer with an uncross-linked substrate or (2) a graft copolymer of styrene and acrylonitrile on butadiene-acrylonitrile rubber which has been crosslinked with divinyl benzene and a similar graft copolymer with an uncross-linked substrate.

Title: Heat transfer
IPC: C02F1/06
Filed: 1968-12-04
Abstract: Saline water, such as sea water, flows down column 10 (Fig. 1) and up column 11 which is heated at the base e.g. by injection of steam at 14 successive evaporation of some of the water takes place as the saline water rises up column 11, and the vapours collect under plates 17 and pass through apertures 13 into column 10 where the vapours condense in the downflowing saline water thereby heating it so that salts such as calcium sulphate are precipitated and can be withdrawn through outlet 22. Softened water is collected in vessel 7 which is at a lower level than vessel 6 so that the flow of water takes place by pressure difference. Air is withdrawn from the apparatus by ejector 8. The two columns may be arranged at concentric tubes. Fig. 6 shows a plant wherein a heat-transfer apparatus 30 of the type specified above is associated with a multi-stage flash evaporator comprising one flash section B at high temperature, a heater 31 and two flash sections A and C at low temperature. Saline water is introduced into the plant through inlet a and desalinated water, which is collected in condensate trays below coils 32, 36, 37, is withdrawn through outlet c. Calcium sulphate is discharged through outlet d. Brine is withdrawn through outlet b some of this brine is discharged and the remainder is recycled to the flash sections by pump 35. Fig. 7 (not shown) illustrates a multi-stage flash evaporator associated with a heat-transfer apparatus comprising two units (30') and (30").

Patent ES-372537-A1 (ES)
Title: Digital code receiving system
IPC: G08C25/00
Filed: 1969-10-15
Abstract: A digital code receiving system (see Division G4) includes a number of decoders each responsive to a given digital code and each including four gates two of which are shown in Fig. 3. Each gate includes two transistors Q1, Q2 and Q3, Q4 which control the energization of polarized devices 75, 76, and further transistors Q5, Q6 used as inverters to control the transistors Q1, Q2 and Q3, Q4. The transistors are turned on in response to a mark applied to the respective code buses 27-34. With transistors Q1 and Q2 turned on the device 75 is energized to provide an output on lines 77 and 78. No output is delivered if either of the transistors Q3 and Q4 are turned on or shorted. In the receiving system after an output has occurred from the device 75 the incoming code is complemented and the two pairs of transistors Q1, Q2 and Q3 and Q4 exchange roles. The polarized device is shown in Fig. 4 and includes an oscillator including a transistor Q7 operable in response to positive and negative energization of the input wires. The generated frequency is applied via a transformer 82 and diode 83 to the base of an output transistor Q8 which is turned on only if the correct polarization has been applied to the inputs to the device. The diode is included to prevent the device operating in response to an abnormally low level input. The device is fail safe in that if transistor Q7 is shorted no voltage is induced in the transformer secondary. Each decoder produces a pulse on one line in response to its associated code and a pulse on a second line in response to the complement of that code and a control device, Fig. 5, responds to these two pulses by energizing a relay CR. The relay is energized by the discharge circuit of capacitor 87 through a switching transistor Q9 which is switched on by the pulse produced in response to the complementary code and switched off, thereby making a charging circuit for the capacitor 87, by the pulse produced in response to the code recognized by the decoder.

Title: Method of and circuit arrangement for picture transmission using multiplex techniques
IPC: H04N7/12
Filed: 1970-07-15
Abstract: The method and circuit arrangement for transmitting video pictures over a telephone line using time division multiplex techniques.

Each picture is divided into two partial pictures or images, each capable of transmission within a discrete pulse or time slot. The partial picture received during one time slot is stored until the second partial picture is received during a subsequent time slot, thereby completing the picture. The complete picture may then be released from the receiving end to suitable picture processing or display equipment.
