Title: Timing systems for electronic timepieces
IPC: G04G3/02
Filed: 1972-08-22
Abstract: 1398537 Electronic watches BULOVA WATCH CO Inc 22 Aug 1972 [27 Aug 1971] 39143/72 Headings G4D D7X D6Y D6C1 and D6C2 The high frequency standard for a timepiece operates at a frequency less than an ideal frequency and additional pulses are injected into a frequency divider arrangement to provide a number of useable pulses in a set time that equals the number obtainable from the ideal frequency source. The frequency source 10, which conveniently is a crystal controlled oscillator, supplies a main divider section 11 consisting of n stages of binary division connected in series which supplies a display 12 which may be a liquid crystal, electroluminescent or mechanical time indicator. The output is also supplied to a supplementary divider 13 which has m stages and supplies a pre-set section 14 which is connected to the inputs of L stages of the main divider. Thus over a set time the number of deficient pulses is added in either as an initial setting to the divider for each set time or by distributing them evenly during the set time. The number to be added can be pre-set in the divider by making specific connections or alternatively by providing a memory circuit, including bi-stable elements, which can be externally set to regulate the timing. It is stated that a radio-active source emitting α-particles may be used as the frequency source.

Abstract: 1,126,470. Treating textiles. LINEN INDUSTRY RESEARCH ASSOCIATION. 27 Sept., 1965. [25 Sept., 1964], No. 39147/64. Heading DIP. Yarn whether incorporated in a fabric or not is subjected to a treatment which produces a yarn having invariable manner through the cross-sections of the yarn a property, such as the ability to shrink, swell or extend, which can be subsequently activated by a further uniformly applied treatment, the treatment comprising subjecting the yarn to to process which is controlled so that only the outer filaments or fibres of the yarn are affected so that a yarn is produced different parts of the cross-section of which will respond differently to the further treatment. Linen fabric may be mercerised by passing it once through caustic soda liquor under tension, iminedaitely washed while held under tension and stenter dried, the treatment being carried and as rapidly as possible under tension with no delay period so that the caustic liquor is prevented from penetrating entirely through the cross-section of the consistent yarns of the fabric. The fabric may subsequently be shrunk with caustic soda liquor of mercurising strength using a delay period of necessary, washed free of caustic soda on a tensionless machine and dried, the outer parts of the yarn which were affected by the mercerising liquor in the first pant of the treatment shrinking less than the other parts, the differential fibre shrinkage which occurs in the second pant of the treatment causing an opening of the yarn structure. Alternatively the fabric may be treated with a cross-linking agent in the presence of a swelling agent whilst under restraint the outer filaments or fibres only of the yarn being affected so that subsequent treatment with caustic soda of mercerising strength causes the outer and inner filaments or fibres to shrink differentially.

Title: Method of heating metallurgical and like products and a furnace for performing the same
IPC: F27B9/36
Filed: 1970-08-14
Abstract: 1311298 Conveyers for furnaces SOC ANON HEURTEY 14 Aug 1970 [19 Aug 1969] 39221/70 Heading F4B A furnace, heated by downwardly radiated heat from its roof, is provided with a conveyer (not shown) preferably of the walking beam type which advances metallurgical products 5 along its hearth in cyclic steps, each step being made up of sequential movements of the products in alternating directions and of differing extents. In this way uniform heating of the undersurfaces of the products by absorbed heat re-radiated from previously uncovered hearth areas is attained. Thus for products having a length 6 to mutual spacing 4 ratio of 3 : 1, each product, e.g. 5a, Fig. 1, is moved one increment or one-third of its length forward to the Fig. 2 position to uncover hearth area 7c, and to cover up previously uncovered hearth area 7b by the leading third of its length which absorbs heat therefrom. It is then moved one increment back, so the back third of its length, see Fig. 3, once more covers hearth area 7c to absorb heat from it, and area 7d is uncovered. Finally to complete one cyclic step, it is moved two increments forward to the Fig. 4 position in which the middle third of its length absorbs heat from the now covered hearth area 7d, and a fresh area is uncovered downstream of it ready for the next cyclic step. The hearth includes an upper heat accumulating and conducting layer 2 of refractory brick or chromium containing cement, and an insulating backing layer 3.

Abstract: 884,008. Feeding quills to yarn-stripping apparatus. DEERING MILLIKEN RESEARCH CORPORATION. Dec. 19, 1957 [Dec. 19. 1956], No. 39577/57. Class 120(3) Apparatus for separating and feeding entangled yarn-wound quills comprises a reciprocating shaker conveyer 19 and a yarn cutter 65 lower than, and adjacent to, the discharge end of the conveyer. The quills, which may be interconnected in groups by entangled yarn ends, and are to be fed to a yarn-stripping apparatus 191, are placed in a bin 11. Conveyer 19, which is stepped, forms part of the floor of bin 11. Baffles in the bin, which ensure that bobbins are fed on to shaker 19 from the rear and one side only, and a weighted door 57 prevent quills from jamming in the discharge opening. Shaker 19 feeds quills over a plate 69 having V-shaped notches which guide the yarn ends between pairs of roll cutters 65. From plate 69, the quills fall on to a pivoted floor 81 and thence pass to a second shaker 89. A pivoted overhead "door" 101 provides an approximate one-by-one discharge of quills from shaker 89. A second guide plate 109 and cutters 115 sever the yarn ends which escaped cutters 65. From plate 109, quills are discharged into a supply hopper 117, having a pivoted floor 119, feeding a troughshaped conveyer 131 the sides of which are formed by endless belts 135 inclined to each other and to the horozintal. The quills are conveyed along slot between belts 135 with their heads supported in the belts. A pair of roll cutters 145, with an associated guide plate 147, sever upwardly-extending yam tails. Belts 135 feed quills to a slide 181, 183 in which they are frictionally retarded by a bar 185 and which discharges them to stripper 191 in a continuous flow. Shakers 19, 89 are respectively reciprocated by air motors 30, 91 controlled by solenoidoperated valves. By appropriate switch control of the solenoids motor 30 is stopped by weightoverload of floor 81 or, optionally, by movement of door 101; motor 91 is stopped by weightoverload of floor 119, movement of a ball 161 consequent on a pile-up of quills on belts 135, or simultaneous movement of two switches 163, 165 consequent on a back-up of quills on belts 135. Photo-cells may be substituted for switches 163, 165, and a time-delay relay may ensure that shaker 89 is not stopped by a series of pulses caused by quills passing in succession. In a modification, a single bin is designed to supply two or more spaced shakers. Specification 884,009 is referred to.
