Title: Improvements in thermionic valves and valve circuits
IPC: H01J21/20
Filed: 1933-05-15
Abstract: 419,731. Thermionic valves; valve circuits. ROBINSON, E. Y., Garvary, Dryden Road, Bush Hill Park, Enfield, Middlesex, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. May 15, 1933, No. 14108. [Classes 39 (i) and 40 (v).] In a thermionic valve having an indirectly heated cathode, or several such cathodes with a common heater system, the heater system in either case is provided with at least one tap which divides it into equal electrical sections, said tap or taps having no connection within the valve to a cathode and being separately brought out of the valve to enable heaters of unequal wattage to be employed in alternative series or parallel connection. In the arrangement shown in Fig. 1, valves 4, 5 having centre tapped heaters are connected in series with ordinary valves 1, 2, 3 of half the heater wattage and a ballast resistance 6, enabling connection to be made by a plug 8 to A.C. or D.C. supply mains. Connections from the tappings 10 and the ends of the heaters are taken alternately to groups of insulated contacts 11, 12 adapted to be connected by the switch 13 to the poles of a car battery 14. The sections of the tapped heater, which may consume 0.2 ampere at 12 or 13 volts, will thus operate in series or parallel connection. If the anode supply is independent of the car battery, the full-wave rectifier 5 is not included in the parallel connection, as shown, but if a vibratory generator is used one or both sections of the rectifier may be employed. The switches 8, 13 may be interconnected to prevent simultaneous connection. A power pentode is described having a double hairpin heater, with a separate connection to its electrical centre. In a " Class B " valve shown in Fig. 4, two cathodes 43 have a common heater system 44 with a centre-tapping connection 46. The cathodes may be connected inside the valve, or brought out to separate contacts for independent biassing &c. A rectifier valve such as 5 in Fig. 1 may be similarly constructed, separate cathodes being provided and the grids omitted. Specification 278,787, [Class 39 (i)], is referred to.

Filed: 1947-05-28
Abstract: 631,210. Electric filters. SANDEMAN, E. K. May 28, 1947, No. 14186. Drawings to Specification. [Class 40 (viii)] An electric filter of the kind comprising two lengths of the same kind of transmission line arranged in parallel between two input terminals and two output terminals, is provided with means to vary the electrical length of each path in such a way that as one increases the other decreases maintaining the sum of their electrical lengths constant. In one construction a closed loop is formed of two wire transmission line, with input terminals at one point and output at another. By forming either or both of these terminals as sliding contacts, the two paths from the input to output may be varied in length whereas their sum remains constant and equal to the circumference of the loop. A loop of coaxial line or a wave-guide may be used in alternative constructions. In this case the outer sheath must be slotted to permit slidable probes or similar adjustable terminals to be used.

Title: Process for producing textured polyester multifilament yarn
IPC: D02G1/02
Filed: 1975-04-08
Abstract: 1510171 Polyester yarn TEIJIN Ltd 8 April 1975 [15 April 1974] 14399/75 Headings D1F and D1W In a process for making textured polyester multifilament yarn, melt-spun linear ethylene terephthalate polyester filaments having a birefringence value of at most 0.04 are wound up without drawing, and before and/or after winding a finishing agent not capable of diffusing into the filaments but capable of preventing formation of protuberances having a surface protuberance number larger than 5 on the surface of the filaments when the treated yarn is twisted without drawing, at a twist number of 32,500 divided by the square root of the yarn denier, and untwisted, the treated yarn having been first aged at a temperature of 40‹C and a relative humidity of 70% for 21 days, the treated yarn being then subjected to a simultaneous or sequential draw-false-twisting operation. The surface protuberance number is determined by counting the number of protuberances revealed by a scattering electron microscope having a magnification of 1000 in a filament portion having a length equal to the filament diameter. The finishing agent may include an ester oil lubricant, a polyether lubricant consisting of copolymers of propylene oxide and ethylene oxide having a molecular weight of at least 2000, a non-ionic polymeric surface active compound having branch groups having 0 to 50 carbon atoms, or a mixture of two or more of these substances. A reduction in the number of protuberances resulting from the use of the non-diffusing finishing agent is said to produce a textured yarn which. when aged, was even in quality, particularly in dye-absorbing property.

Title: Improvements in and relating to reservoir writing instruments
Inventor: FEHLING HANS REINHARD
IPC: B43K1/08
Filed: 1946-05-13
Abstract: 688,891. Reservoir pens. COMPANIA URUGUAYA DE FOMENTO INDUSTRIAL SOC. ANON. Sept. 12, 1947. [May 13, 1946 ; June 3, 1946] Nos. 14406/46 and 16831/46. Class 146,(iii). An ink reservoir for a ball-point pen has a diameter of not more than 6mms. and is equipped with a piston which has a "bulk" density (i.e. including cavities therein) the same or nearly the same as the density of the ink and which is a close sliding fit in the reservoir, so that the piston floats on and moves along the reservoir, with the ink surface and prevents seepage of ink. The floating piston 4 may be hollowed out as shown and may have attached thereto or contacting it on the side remote from the ink a flaccid tubular bag 5. The latter is secured by a clip 6 at its open end to the outer wall 2, and prevents leakage of any ink which seeps past the piston. The inside of the tube is open to the atmosphere through a passage 7. The piston is conical at 4a so as not to trap any air when it is inserted in the ink. Further, the piston diameter may be decreased at the side remote from the ink (see Fig. 6), so that ink drawn into the gap by capillary forces does not reach the end of the piston. In all cases the arrangement is such. that the piston follows and remains in contact with the surface of the ink whatever the position of the pen. In place of the bag 5, an extra piston may be employed and may be lubricated with a high-viscosity lubricant ; it may contain an air passage leading to the inktrap space between the pistons. Alternatively, or in addition to the extra piston an absorbent pad may be used. In another construction, Fig. 6, the piston 22 floats on the ink in the non- writing position of the pen. It slides on a central capillary tube 24 leading to the feed duct in the point section 26. An air-hole 27 is provided above the piston 22 and an absorbent pad 25 prevents leakage. The point section may be formed as described in Specifications 564,172, 609,817 and 650,754 Inks. A suitable ink contains an oleaginous solvent (e.g. olein, castor oil, ricinoleic acid or a combination thereof), an adhesive thickener (e.g. colophony) and a dye (e.g. aniline). A small proportion of a metal soap (e.g. sodium oleate) may be added. Proportions are given. Specifications 573,747 and 621,847 also are referred to. Reference has been directed by the Comptroller to Specification 615,548.

Abstract: 626,180. Filleting fish. FISADCO, Ltd., and FARRER, E. R. B. June 2, 1947, No. 14583. [Class 28(ii)] In a fish filleting machine in which the fish is drawn tail first past main filleting knives and in which succeeding blade knives enter the previous filleting cuts and move towards the tail clamp faster than the travel of the fish so as to cut off the tail root as in Specification 491,452 the blade knives 5, 6 are caused to open out from one another to prise out and then sever the fillets from the tail root. The blade knives and their operating mechanism are carried on a rotating shaft 2, and are actuated by cam grooves in a fixed plate 14. The blade knives 5, 6, have sickle shaped edges and are secured to plates 30, 31 which are forced by cams to rock through 45 degrees to make the knives open out to V-shape, Fig. 1. The cutting edges of 5 and 6 then move away from the backbone to prise the flesh off. Each blade knife moves into the already made filleting cut and in its movement severs the fillets at the tail, the cutting movement being towards the tail clamp 100 so as to tend to push the fish into a clamp, instead of a pull-away cut so avoiding risk of tensile break away of the body from the tail. The blades 5, 6 are carried by a rotary structure mainly as in Specification 491,452. The structure comprises a rotary shaft 2 carrying a sleeve 3 of a plate 7 carrying the knife structure the plate being oscillated in timed relation by a linkage 8, 9, 10 carrying a cam roller 12 operating in a fixed cam slot 13. A hill-and-dale fixed cam slot 19 operating on a roller 18 oscillates a bellcrank 17 to which is geared at 24 a similar bell crank whereby the fillet clamps 15, 16 open and close on their anvils 40, 41. A bell crank 60 carrying a cam roller 63 running in a cam slot 13 is rocked whereby rod 55 slides to and fro whereby a plate 54 reciprocates and its slots 52, 53 move pins 50 and 51 on plates 30, 31 to make the knives open out into V-shape so that their cutting edges move away from the backbone. Before the tail is cut off each fillet is seized and held between a clamp 15 and its anvil 40. Specification 454,496 also is referred to.
