IPC: D04H3/07
Filed: 1951-08-21
Abstract: 713,543. Fabrics composed of adhesivelyunited threads. OWENS-CORNING FIBERGLASS CORPORATION. Aug. 21, 1951, No. 19715/51. Class 140 An open mesh fabric is made by moving a group of spaced parallel strands in a direction lengthwise of the strands, applying an adhesive coating to the strands, and laying one or more other strands on to the group of strands in a crosswise direction. In modifications, the adhesive may be applied to a single strand forming the crosswise elements, or the application of adhesive may be dispensed with where heatsoftenable or fusible strands such as cellulose acetate are assembled with heat-resistant material such as glass fibres, strands or yarns, union of the crossing strands being effected by heating the assembly. Threads 31, Fig. 1, drawn from bobbins 30 pass under a ring 33 supported by bars 34 welded to the ring and to a fixed framework 11. The threads are drawn upwardly in the form of a hollow cylinder, pass around a guide ring 54 provided with spacing fingers 56, downwardly under a second ring 58 which is immersed in a bonding material, e.g. heated asphalt, in an annular trough 46, and then resume their upward path in cylindrical formation. Threads are wound crosswise on the upwardly travelling cylinder of yarns, being led through guide eyes in brackets 81 from bobbins mounted on an annular platform 66 which is rotated by a belt drive from electric motor 75. The adhesive is set or hardened by heating, e.g. by gas jets 87, the fabric tube is passed over a set of rings which gradually change it to flattened form, the flattened tube is suit into two webs, e.g. by electrically-heated wires, and the webs are led off over feed rolls 36 to winding-up rollers 41. Two annular platforms rotating in opposite directions may be used to produce a fabric with oppositely inclined weftlike elements. The bonding agent may be applied to the warps by spraying. In an alternative form of apparatus threads 31<11>, Fig. 11, from bobbins 30<11>, are led upwardly as a hollow cylinder after passing around a ring 130 with spacing fingers 129; and pass downwardly as a hollow cylinder surrounding the first, after passing around ring 133. A glass strand 84<11> formed from molten glass extruded as a number of filaments 157 from orifices 156 is adhesive-coated while passing around a pulley 158, passes through a centrally-disposed guide 160, and is laid on the downwardly descending cylinder of warps by a-pulley 161 freely mounted on a cap 141 mounted on a vertical shaft 139 rotated by electricmotor 151. The adhesive is set by gas jets 176 and the fabric tube slit into two or more webs which are wound up at 174. The warp components may be cotton strands or yarns, on which cross-wise strands of cellulose acetate or nylon may be applied, or one or both. sets of components may consist of glass fibres. The adhesive may be starch, sugar, gum, polyvinyl chloride, acetate, vinyl chloride-acetate copolymer, polymethyl methacrylate, urea- or phenol-formaldehyde resin.

Abstract: 722,899. Reservoir pens. KOVACS, T. Aug. 23, 1951 [Sept. 4, 1950; Sept. 8, 1950], No. 19880/51. Class 146 (3). A reservoir pen has a cap 8, preferably of metal, screwed on the nib end 5 of the barrel by a thread 6 of coarse pitch co-operating with an internal thread 15 formed in a part 3 attached to the cap.. The threads may be multistart threads, for example,ten-start threads. A fixed or rotatable ring 9, which prevents unintentional unscrewing of the cap 8, is disposed around the barrel for frictional engagement with.the interior of the cap ; the ring 9 may be split, in which case it has a larger outer diameter than the internal diameter of the cap. When the cap is fully screwed on, the open end of the cap engages an abutment on the pen barrel formed by a reduced neck 7. The distance a, between the leading edges of the thread 6 and ring 9, is equal to or greater than the distance b between the rear edge of the thread 15 and the open end of the cap 8, such that the co-operating threads 6 and 15 engage before .the ring 9 contacts the cap 8. A ring, not shown, similar to the ring 9 may be provided to retain the cap on the rear end of the pen, short guide surfaces being provided in this case to engage the threads 15.

Title: Improvements in or relating to the energization and control of thermionic valves particularly for use in wireless reception
IPC: H01L35/00
Filed: 1924-08-25
Abstract: 231,819. Sabin Electrical Products Corporation, (Assignees of Sabin, B. E.). April 7, 1924, [Convention date]. Thermionic amplifiers and detectors; undesired signals, eliminating.-The filament current, plate voltage, and grid-biasing potential of a valve receiver are derived from alternating or direct current supply mains through the intermediary of a thermo-electric batterv of the kind described in Specification 219,296. The current from the mains heats a resistance element, which in turn feeds the hot junctions of the thermopile. As shown in Fig. 1, the thermopile is in three separate sections. The section 10 supplies the filament current, section 11 the plate tension, and section 12 the grid bias. In Fig. 2 the various sections are combined into one battery, switches 41, 42, 43 being provided for tapping off the desired voltages to the various parts. The battery is stated to be suitable for multivalve receivers of the super-heterodyne and neutrodyne types. A filter circuit, comprising inductances in series and capacities in shunt, is interposed between the power mains and the thermopile in order to eliminate commutator noise.

Ornamenting. - Pottery-ware which has been blackened during firing by deposition of carbon is ornamented by removing parts of the carbon deposit by oxidation, thus revealing the natural colour of the clay. In the prepared process a paste of clay with an oxidizing agent, for example potassium chlorate, is applied in a pattern to the blackened surface, and the article is heated to a temperature sufficient to release the oxygen, but below that at which the clay is fired. By suitable selection of the clay used in making the ware different colourings may be produced in different parts of the figuring.

Title: Improvements in or relating to spool changing in winding machines
IPC: B65H67/04
Filed: 1961-06-05
Abstract: 927,040. Winding and doffing spools. HEBERLEIN & CO. A.G. June 5, 1961 [June 8, 1960], No. 20231/61. Class 120 (2). The package b 1 , Fig. 2, is driven by a grooved drum a and when the shaft b 2  reaches the top of a guide groove d 1  the package is raised manually and deposited in a groove h 5  of a support h, Fig. 3. This causes the thread g to be draped over an empty spool e resting in a notch h 4  of the support h such that the spool e is in driven engagement with the drum a. The drum a and the spool e feed the thread g to the now stationary package b 1 so that the thread develops into a loop i 1  that increases in magnitude until it is of a size i sufficient to be caught between the spool e and a roller f driven by the spool e. The thread g now wraps around the spool e and is broken from the package b 1 . Spool e is then raised manually and placed with its shaft e 1  in the groove d 1  and the grooved drum a then continues to drive the spool e and guide the thread g thereon. The support h and associated arm h 1  is removable. In a modified construction, Fig. 5, the package b 1  is again driven by a grooved drum a and as the package increases in diameter its shaft moves up a groove p 1 . When the shaft reaches the top of the groove p 1  it rolls down the groove p 2 , thus carrying the finished package away from the drum a, Fig. 7. This motion of the package b 1  draws the thread g on to an empty spool e supported on one arm t 1  of a twoarmed lever t and, at the same time, a lever o is displaced by the package such that a spring- biased linkage system n, m, v rocks the lever t anti-clockwise, Fig. 9, to raise the spool e and align its shaft e 1  with the groove p 1 . The drum a and spool e now feed the thread g to the stationary package b 1  so that the thread develops into a loop q 1  that increases in magnitude until it is of a size q sufficient to be caught between the spool e and the driving drum a. The thread g now wraps around the spool e and is broken from the package b 1 . After the package b 1  has been removed, the lever o can be manually depressed to rotate the lever t back to the position shown in Fig. 5.
