Title: Improvements relating to means for electrically heating parts of electric discharge devices
IPC: H05B41/06
Filed: 1934-12-21
Abstract: 430,475. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. f³r Elektrische Gliihlampen; 11, Ehrenbergstrasse, Berlin) Dec. 21, 1934, No. 36719. Convention date, Dec. 22, 1933. [Class 39 (i)] [See also Groups XI and XXXVII] Means for electrically heating a part of a discharge device comprises a switch which by its closure short-circuits a resistance, and a timing resistance in series with an electromagnet operating the switch, the timing resistance having a negative temperature coefficient and the arrangement being such that the resistance remains short-circuited until the timing resistances reaches a predetermined temperature. In one form, Fig. 1, the heating element 3 is supplied from mains 1 through a resistance 2. At starting, the switch 5 short-circuits ths resistance, but as the timing resistance 7 warms up the current through the electromagnet 6 increases, eventually opening the switch 5. In a modification, the timing resistance 7 and magnet 6 are in series with the resistance 2, and the whole group is shunted by the switch 5 and a resistance in series with it. Fig. 4 shows the various members connected in a circuit of this kind and mounted in an envelope filled with hydrogen, nitrogen or a rare gas. The resistance 9 is in series with the switch 5 and the resistance 2 is in series with the coil 6 and the timing resistance 7. The switch may be placed in a cap of the envelope. The resistance 7 may be of chromium oxide, in which case it must be pre-heated, for example by the resistance 9, or of uranium oxide, and the resistances 2 and 9 may be of refractory metals and may be constructed so that they become incandescent in operation. Fig. 5 shows the invention applied to the cathode heating circuit; in this case the anode to cathode path 2 serves as resistance and is initially short-circuited by the switch 5. If it is desired to heat the cathode during operation by means additional to the discharge current the switch 5 may be shunted by a resistance.

Title: Improvements in or relating to a method of producing a food-stuff
IPC: A23L19/18
Filed: 1955-12-22
Abstract: A dry material used for producing a fried, crisp food-stuff is prepared by mixing a dry, mainly starch-containing powder with sufficient water to give a mixture of 30 to 40% moisture content, extruding it at a pressure of at least 6 atmospheres to form a coherent ribbon, and drying the ribbon either in continuous lengths or as separate pieces to a moisture content of 6 to 10%, the extruded and dried material being then ready for frying in hot oil.  The starch-containing powder is preferably made by stewing or cooling potato tubers followed by drying or milling to produce a powder.  A starch-containing cereal powder, i.e. rice powder, can also be used. Up to 50% of the powder can be replaced by another starch-containing powder consisting mainly of starch grains which are preswelled by combined heat and moisture, followed by drying and powdering.  An admixture of up to 15% raw starch powder is also possible.  In an example, potato powder of 11% moisture content and of such a grain size that 99% passes a 45-mesh B.S.S. screen, is mixed with water and, e.g., seasoning such as salt or spices, and the mix is extruded as ribbon at about 9 atmospheres pressure.  The ribbon is dried to a final moisture content of 8% with hot air, cut into pieces and fried in hot oil at 180 DEG  to 200 DEG  C. for about 7 seconds. Specifications 687,015 and 750,217 are referred to.

Abstract: 817,268. Transistor oscillator circuits. GENERAL ELECTRIC CO. Dec. 23, 1955 [Jan. 26, 1955], No. 36878/55. Class 40 (6). In a transistor circuit having a tuned collector load, the base of the transistor is connected to a bias source through a negative temperature coefficient resistance so as to vary the bias with changes in ambient temperature to compensate for variations in a frequency characteristic of the circuit. The Figure shows a Colpitts oscillator comprising an N.P.N. junction transistor 11 coupled to a tuned circuit 21, 22, 23, 24 and having its base connected to a potentiometer comprising a fixed resistor 17 and a negative temperature co-efficient resistor 18 chosen to adjust the base potential and thus the transistor input capacitance as the ambient temperature changes in such a manner that the oscillation frequency remains constant. When the temperature characteristics of the transistor are such that the oscillation frequency tends to rise with increase in temperature the resistance 17 instead of resistance 18 must have the negative temperature coefficient. The invention is also applicable to tuned amplifiers.

Title: Process for preparing dry water-soluble dyestuffs
IPC: C09B67/54
Filed: 1966-08-19
Abstract: A process for preparing a dry water-soluble dye comprises crystallizing the dye from a concentrated aqueous salt solution, separating the crystalline dye from the concentrated salt solution as a wet crystal magma, washing the adherent concentrated salt solution from the said magma with a water-miscible organic solvent of boiling point below 180 DEG  C. and drying the washed magma.  Specified solvents are acetone, methylethyl ketone, dioxane and preferably alkanols.  In an example sodium chloride was added to a slightly alkaline aqueous solution of Tartrazine containing disodium phosphate at 50 DEG  C. and crystallization induced by seeding and cooling to 0-5 DEG C.  The crystals were filtered off, washed with sodium chloride solution, blown to remove adherent liquor, washed with ethanol until 75% of the salt solution was removed (indicated by specific gravity of the wash liquor) and dried at 70-80 DEG  C.  A dye of improved tinctorial strength when mixed with sugar was obtained.  The monoazo dye 1-(4-sulphophenylazo)-2-hydroxynaphthalene-6-sulphoni acid (Na salt) was similarly treated.

Abstract: 1,201,372. Two-part couplings. GENERAL ELECTRIC CO. 16 Aug., 1967 [6 Sept., 1966], No. 37805/67. Heading H2E. A flat contact 76 is gripped by a pair of opposed curved blades 94 cut from a metal sheet 86-88, the blades having contact-engaging portions 92 which lie parallel to the inserted contact 76. The blades 94 resist withdrawal of the contact 76 owing to their curved nature, and cut-outs adjacent the blades 94 reduce stress on the metal sheet. A single metal sheet may include a row of contact blade pairs arranged for insertion of flat contacts from opposite sides of the sheet. Four such sheets 20, 22, 24, 26, Fig. 2, are moulded in a resilient insulating body so that live and neutral contacts 30, 32 of a plug engage blades of the sheets 20, 22 and the plug earth contact 28 engages blades of either the sheet 24 or the sheet 26, depending on the insertion direction of the plug. In another arrangement, (Figs. 20-22, not shown) each side-piece of a U-shaped metal strip is formed with a contact blade pair (140) and an elongated slot (138) arranged in a T, so that a flat contact can be inserted in either of two perpendicular directions to engage the blade pair of one T and the slot of the other T. Instead of being formed as in the Fig. 7 arrangement, the blades may be constituted by rolled-over opposite longitudinal edges (114, Figs. 11-17, not shown) of a metal strip (120) which are bent into facing relationship, the edges (111) of a central longitudinal slit (112) in the strip being bent outwardly to define a contact-receiving slot.

Title: Improvements in mechanisms for use in continuous counting
IPC: G06M1/04
Filed: 1946-12-24
Abstract: 624,122. Counting-apparatus. BRECKNELL, MUNRO & ROGERS, Ltd., and DOLMAN, H. J. Dec. 24, 1946, Nos. 37845/46 and 26202/47. [Class 106 (i)] A mechanism for counting the total number of operations of several appliances comprises a rotary distributer carrying in differing phase relationship several displaceable toothed members, each of which co-operates with a trigger associated with one of the appliances and releasable thereby to cause the toothed member to move into a position in which it actuates once a rotary driver connected to operate a counter. For converting the operations of two groups of appliances, the triggers 46 are arranged in two rows corresponding to two shafts 6 and 7, Figs. 2 and 4, which are driver by an electric motor 11 either continuously on for at least one revolution whenever an electromagnet 48 is energized by the operation of an appliance to release a trigger 46. The release of a trigger permits a pawl 51, carried by a cam disc 17, to engage a ratchet-wheel 16 secured to, say, the shaft 6, and thereby causes the corresponding disc 17 to rotate for one revolution so as to lower a cam surface 60 on a yoke 56 in order that it may engage a projection 61 on a toothed member 23 pivoted to a disc 14 rotating with the shaft 6. The toothed member thus engages, and moves on by one step, a spur-wheel 45 secured to a rotary driver 27 geared to a counter 30. A lever 66, or according to the first Provisional Specification, a second toothed member, is also pivoted to the rotating disc 14 so as to be engaged by the lowered cam surface 60 in such a way as to rock the toothed member 23, or to be rocked itself, to step on a second spur-wheel 45 on a rotary driver 28 which is also actuated by the corresponding toothed member 23, when it is caused to project, of the shaft 7. The rotary driver 28 is geared to a counter 31 which registers the total number of operations of both groups of appliances. A third rotary driver 29 is actuated by the toothed member on the shaft 7 only and is geared to a counter 32. Over-driving of the rotary drivers may be prevented by providing each with a sprung escapement mechanism (Fig. 5, not shown), or with a sprung lever which, by engaging notched discs on the rotary driver and corresponding shaft 6 or 7 respectively, synchronizes the movements thereof (Fig. 6, not shown). In a modification, Fig. 7, each rotary driver is formed by a ratchet wheel, such as 82, geared to the counter 32, and is spring-urged against a rotating friction ring 91, which may be secured on the shaft 6 or 7. The ratchet wheel 82 is normally prevented from rotating by a pawl 85 which, however, is tripped by a link 88 when a shaft 79 is rocked by the engagement of one of the toothed members 23 of the corresponding shaft 6 or 7 with an arm 80 on the shaft 79. The rotary driver 82 is thus permitted to move on by one tooth. A shaft 92 carrying a series of arms 93, 94 is actuated by any projecting teeth on both of the shafts 6 and 7 and controls a rotary driver geared to the counter 31.
