Title: High-frequency heating devices
IPC: H05B6/48
Filed: 1970-03-12
Abstract: 1293021 Dielectric heating SIEMENS AG 12 March 1970 [14 March 1969] 12019/70 Heading H5H Dielectric heating apparatus comprising a conveyer 3 for transporting material to be treated through a high frequency field formed between a main electrode 1 and the conveyer 3 which acts as the other main electrode, is provided with auxiliary electrodes 10 to 13 positioned between the conveyer 3 and electrode 1 which alter the intensity of the field at these positions. If, as is the case in drying cakes of yarn 4, it is desired to reduce the field intensity to which the material is initially subjected, the auxiliary electrodes 10-13 are earthed, as is the main conveyer electrode 3. If it is desired to increase the field intensity at certain points some of the auxiliary electrodes 10-13 are insulated from the main electrodes. The yarn cakes 4 are positioned between insulating discs 5 and equipotential covers 6. The main electrode 1 has rounded edges and extends longitudinally whereas the auxiliary electrodes extend transversely or at an acute angle to the main electrode 1. The electrodes 10-13 are  mounted on vertically adjustable supports 14 which may (Fig. 3, not shown) be provided with sawtooth notches to locate the auxiliary electrodes at different desired spacings. The auxiliary electrodes may be plates (Fig. 5, not shown), solid copper rods or hollow copper tubes. Such tubes may be of elliptical cross-section and they and the plates may be eccentrically pivoted to enable fine adjustment of the field intensity. The main and auxiliary electrodes may be heated by external radiant heaters, or when they are hollow by internal radiant heaters. The length of the transverse auxiliary electrodes 10-13 is greater than the width of the main electrode 1 to intercept stray fields. The auxiliary electrodes may extend parallel to the main electrodes. The auxiliary electrodes may be adjusted according to a preset programme. The device may be used for drying foundry cores or sugar and for altering the chemical composition of a material by heating.

Abstract: 163,967. Gouldbourn, J., Ricks, F., and British United Shoe Machinery Co., Ltd. Feb. 16, 1920. Chain-stitching machines; needles, dividing; rotary horns; presser bars with periodic control; feed by presser and the like; driving; starting and stopping gear.-The main driving shaft extends from front to rear of the machine and is provided with a hand-wheel 184. The stroke of the needlebar is determined by the position of the horn, which rises and falls as the thickness of the work varies, by means of mechanism 13, 15, 21, 23, 35 as described in Specification 10147/11. The presser and feed foot mechanism used is described in Specification 106,454. The speed of the machine is varied, as described in Specification 16186/10, by means of an epicyclic train including pinions 227 carried by a brake drum 213, the shoe of which is controlled from a cam 199 fast on the supporting shaft of the horn. The starting and stopping-gear includes a friction clutch 211 actuated from an inclined gimbal device and controlled from a treadle as described in Specification 720C/07, [Class 80, Mechanism &c.]. In moving the treadle to start the machine, a treadle rod 239 rises and throws in the clutch, the epicyclic gearing imparting the lowest speed to the machine. Further upward movement of the rod 239 raises a lever 231 and, by removing the brake from the drum 213, causes the speed to increase. Thereafter the speed is controlled by the cam 199.

Abstract: 558,501. Measuring short time-intervals; indicating apparatus. HUGHES & SON, Ltd., H. (Bludworth, T. F.). Aug. 31, 1942, No. 12243. [Class 106 (iv)] [Also in Group XVIII] A device for indicating short timeintervals comprises a stack of light transmitting bars having inner and outer ends and means to illuminate the inner end of at least one of said bars at the end of the measured interval of time. The device is shown as applied to echo-sounding apparatus in which a semi-cylindrical shutter 14 is rotated by a constant speed motor, and when in the position shown in Fig. 2 closes contacts to light a neon tube 6 and to send a sound impulse from a transmitter 1, Fig. 1. The signal is reflected from the ocean bed and is received by a receiver 3 and amplifier 5 to extinguish the neon tube 6, at which time the shutter has uncovered a number of bars 13 of translucent material, of which the ends adjacent a scale 10 have been glowing to indicate the depth. Alternatively the neon tube is flashed only when the signal is received. In a modification, the shutter is cylindrical with a small aperture illuminating only one bar at a time.

Abstract: 473,415. Labelling-machines. KIMBALL CO., A. May 3, 1937, No. 12582. Convention date, May 21, 1936. [Class 73] A machine for applying labels having cut-out parts forming tabs consists in means for feeding the labels in strip form to a station where the end label is printed and severed from the strip, the tab being then opened and the label fed forward to engage the article to be labelled, the tab being then pushed back through the plane of the label to secure it. The machine is driven by motor on a shaft 4, Fig. 6, which drives the main shaft 18 through a one-revolution clutch having means for rendering it inoperative for continuous operation. The strip of labels is fed from a reel supply by a reciprocating slide 50 operated by a lever 55 from a cam 58. The label is printed by a printing head 11, Fig. 7, which is oscillated by a cam 70, the type being inked by a reciprocating pad 12 operated by a lever 76 and cam 79. After being printed the strip is fed forward and the end label is severed by a pivoted cutter 82 operated by the printing head. The label is received in a vertically reciprocating member 90 and the tab is opened by a finger 100 pivoted to a slide 102 and the opened tag is pushed by the end of the slide into engagement with the article. The plunger 120 then rises and pushes the tab through the plane of the label.

Abstract: 1,116,009. Photo-electric filament thickness measurement. ZELLWEGER Ltd. March 23, 1966 [May 25, 1965], No.12861/66. Heading G1A. The presence of a double thread where one thread should be is detected by measuring the thread (or threads) thickness in more than one direction so any substantial difference in the measured values indicates a double thread. In Fig. 7 a light beam is directed on to the threads 1 from three different directions in turn as the slit arrangement 15 is rotated about the lamp 2 and projects light along paths B, A and C. The detector 3 effectively produces an A.C. signal superimposed upon a D.C. signal Fig. 8 (not shown): the amplitude of the A. C. represents thickness variations and is evaluated by a discriminator 62 and threshold device 9 for double threads. In another arrangement producing an A. C. signal the light source and detector are mounted upon a disc through a centre-hole in which the thread passes and the disc is either continuously rotated Fig. 3 (not shown) or rotated back and forth Fig. 5 (not shown). Alternatively the thread itself may be twisted and the light source and detector remain stationary. In other arrangements two or three pairs of stationary detectors and light sources scan the moving thread simultaneously; differences in two or three detector signals then provide an indication of double threads Figs .1 and 2 (not shown).
Patent GB-754761-A (GB)
Title: Dewaxing of hydrocarbon oils
IPC: C10G73/06
Filed: 1954-05-04
Abstract: In a process for dewaxing hydrocarbon oils, wherein the oil is dissoved in a hydrocarbon solvent and the waxy constituents of the oil are selectively precipitated, a small quantity of ammonia, less than 2 per cent by weight based on the solvent, is added to the solvent.  During the dewaxing of hydrocarbon oils, employing a hydrocarbon solvent, low temperatures are often used so that any water in the system is converted to ice.  The ammonia depresses the freezing point of the water, thus preventing the formation of ice. Hydrocarbon oils mentioned are petroleum oil fractions such as paraffin distillates and waxy lubricating oils.  The hydrocarbon solvent may contain 2-5 carbon atoms in the molecule, and is preferably liquid propane.  Apparatus is described in which petroleum lubricating oil is mixed with a blend of liquid propane and ammonia, and the mixture is heated to secure complete miscibility, and then cooled to precipitate the wax.  The wax is removed by filtration and the liquid propane and ammonia are recovered for reuse.
