Patent GB-596179-A (GB)
Title: Improvements in or relating to electrical signalling systems
IPC: H02J13/00
Filed: 1945-07-24
Abstract: 596,179. Electric indicators. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and TURTON, G. D. July 24, 1945, No. 18889. [Class 40 (i)] The " closed " or " open " position of a circuit breaker is indicated by a visual glow from an appropriate gas discharge tube CCT3 or CCT4. A change in the position of the breaker being indicated by the extinction of the glowing tube and by an intermittent glow from the other tube. The closure of a circuit breaker momentarily applies a positive potential to the starter electrode of tube CCT1 which becomes conductive. Positive is now connected to the starter electrode of tube CCT3 which becomes conductive and glows steadily if key RSK is in the position shown. When the breaker is opened, a positive potential is applied to the starter electrode of tube CCT2 and the cathode of tube CCT1, so that tube CCT2 becomes conductive and tubes CCT1, CCT3 are extinquished. Positive is now connected to the starter electrode of tube CCT4 which becomes conductive, thus operating relay F which interacts with relay FL to flash tube CCT4 until key RSK is operated, after which the tube glows steadily because F is effectively shunted out. When the breaker again changes its position, CCT1 glows and CCT3 flashes until the key is restored to the position shown. In a modification, Fig. 2 (not shown), the glowing of tube CCT1 or CCT2 indicates the position of the breaker and the function of CCT3 and CCT4 is taken by a single tube which flashes when a change takes place and is extinguished by the reset key. In another modification, Fig. 1 (not shown), only tubes CCT1, CCT2 are used, the glowing of one or the other indicating the position of the breaker. The position of each of a number of circuit breakers is indicated by similar sets of discharge tubes, each set being connected into circuit, as required, via the appropriate contacts of switches A, B.

Title: A method of recovering palm oil
IPC: C11B1/04
Filed: 1950-07-31
Abstract: <PICT:0691266/III/1> Palm oil is obtained from the palm fruit by a combination of steps consisting in dilacerating the pericarp for several minutes at a low or moderate temperature without oil liberation, then causing the oil to diffuse out of the oil-containing cells in a closed vessel by the action of wet steam between about 101 DEG -105 DEG  C, thereupon collecting the virgin drain oil and finally recovering the residual free oil contained in the fibrous mass by any suitable known method, such as by washing or centrifugal action. The pericarp is composed of oil-containing cells assembled with one another and with cellulosic fibres by an intercellular cement of pectic character.  The latter is softened by saturated steam, particularly at 101 DEG  to 105 DEG C, and allows the oil to flow therethrough.  The dilaceration of the fruit is carried out in the cold or at a moderate temperature of 20 DEG  to 99 DEG C, and serves merely to open the fruit for the subsequent treatment with steam. The latter is effected in a closed vessel, wherein the slashed fruits contained in a basket are subjected to saturated steam at 101 DEG  to 105 DEG C.  The oil drips freely and is collected at the bottom of the vessel below the basket.  The residual free oil retained by the fibrous material may be recovered by water washing or centrifuging.  In a suitable plant, a vessel 1, having a perforated base 2 for supporting the charge of fruit, is arranged above a water tank 3 resting on a furnace 4.  The temperature reaches about 80 DEG C in the top part of the vessel.  A shaft 8, driven by a motor 5, has keyed thereto a 4-arm spider 9 carrying cutting paddles 10 with points 11.  The perforated plate 2 carries fixed paddles 12 with points 13 which alternate with the movable paddles 10.  The shaft 8 is rotated for a short time to give the fruits superficial kneading without oil liberation.  The kneading is now stopped and the vessel closed by a cover 14, the heating of the water being continued.  A pressure of 1.2 atmospheres is used, corresponding to wet steam at 105 DEG C.  The oil drains through the perforated plate 2 on to an inclined surface 18 and is removed through a duct 19.  The residual oil is finally obtained by hot water washing, the water from a heater 21 being supplied to a sprinkling ring 22, after the pressure has been released through cock 17.  The shaft 8 is again rotated.  The wash water drains through the perforated plate 2 and is drawn off through the cock 23.  After boiling and allowing to rest, the supernatant oil is decanted.

[Also in Group XIII] A gas burner, Fig. 3, for an air heater, Fig. 2, comprises a bowl shaped inlet 25 leading to a duct 26 and a plurality of gas discharge axially spaced outlets encircling the periphery of the burner and adapted to form an annular sheet of flame of substantial depth. The discharge outlets are formed by an assembly 31 of annular plane and radially corrugated plates arranged alternately. The outer end of the assembly is closed by a plate 32, and two annular plates 29 are mounted at the inlet to the assembly and support a conical deflector 30. Gas is supplied by a jet 14 to mix with air entering the bowl shaped inlet 25. Vanes 33 around the burner body reduce air turbulence. The gas burner is mounted within the' bottle shaped casing 1 of the air heater downstream of a fan 7 driven by an electric motor 6. A guide ring 12 surrounding the inlet end of the burner concentrates the airstream on to the burner flame. The burner is ignited by a pilot burner 16 itself ignited by an electric incandescent element energised by a press button on a control panel on the casing 1. The supply of gas to the main and pilot burners is controlled by a manuallyopened electromagnetic valve 35 held in open position by a current generated by a thermocouple heated by the pilot burner. A thermostat 37 closes the electromagnetic gas valve when the temperature within the heater becomes excessive. The inlet end of the casing 1 is covered by a wire gauze and the outlet end contains vanes 18 to reduce circulatory motion of the air stream. The casing 1 is mounted on a pair of wheels and has a loop handle 5.

Electrical apparatus having a plurality of connecting wires extending from the body of the apparatus is tested by positioning these wires in a two-part jig by sliding one part over the other, spaced grooves being provided in at least one of the opposing faces of the jig and the two parts being so shaped that the wires are guided each into one of the grooves by the sliding movement. The jig shown is for testing the characteristics of small thermionic valves having four projecting connecting wires, and is made of insulating material. The valve 17 to be tested is placed on top of one part 2 of the jig after splaying out the wires in a horizontal plane. The part 2 has four equally-spaced internal grooves parallel to the axis and flared out at the top. The second part 1 of the jig is then brought down over the valve and forced into the part 2 so that the lower end passes right through to the position shown. The projecting wires are forced into the grooves in the part 2. An arm 4 carrying the two-part jig 1, 2 and the valve 17 is then moved to bring the exposed portions of the four wires into engagement with contact-springs 19 which provide the connections for making the test. When this is completed the valve and jig are withdrawn from the contact springs. and the tube 1 is pushed further into the tube 2 until the connecting wires are free of the grooves and the valve is released. The arm 4 forms part of a rotary head which ensures that the arm 4 is correctly positioned over the base 8 when the head is turned, so that the jig is over the contact springs 9. The jig may form part of a machine which moves each valve to a plurality of testing stations in turn for making different tests.
