Title: Improvements in or relating to winding apparatus for slubbings or other threads
IPC: B65H54/42
Filed: 1960-05-13
Abstract: 918,030. Winding threads and slubbings. SIMPSON, J. T., ASPINALL, E., and RATCLIFFE, A. Aug. 14, 1961 [May 13, 1960; July 14, 1960], Nos. 16909/60 and 24504/60. Classes 120 (1) and 120 (2). A loading device for bobbins in a slubbing or other thread winding apparatus in which the bobbin packages are rotated by frictional engagement with one or a pair of driving rollers, comprises a loaded lever and a bobbin engaging lever pivoted on the loaded lever, the bobbin engaging lever transmitting the load from the loaded lever to the bobbin to press it against the driving rolls. In Fig. 1 a bobbin package is forced against two driving rollers 32, 34 by means of a bobbin engaging lever 38 pivoted to a loaded lever 24 pivoted to the machine frame at 26. In Fig. 3 the package presses against a single roller (not shown) and as the package increases in diameter its shaft 52 is forced up a guide 50. To load the bobbin, a bobbin engaging arm 64 is pivotally connected to a loaded lever 60 pivoted to the machine frame at 58. In Fig. 4 an empty bobbin 124 is shown resting on bobbin driving rollers 126, 128. By manually raising a handle 114 a pivoted bobbin engaging lever 108 can be moved upwardly until a hook-shaped end on the lever moves over the shaft 122 of the bobbin. The handle 114 is then lowered so that a weight (not shown) hanging on the lever 112 can force the bobbin 124 against the rollers 126, 128. The apparatus is duplicated at the other end of the winding apparatus and the lever 108 is formed with two hook-shaped ends so that, should it become worn, it can be inverted and exchanged with the bobbin engaging lever 108 at the other end of the frame. In Fig. 6 an empty bobbin 130 is shown resting on a bobbin driving roller 132. By manually raising a loaded lever 136, pivoted at 120, the spindle 134 of the bobbin 130 rolls down an incline 148 on a bobbin engaging lever 142 pivotally mounted at 144 on the lever 136. A cam surface 146 on the lever 142 engages the lever 136 to prevent the lever 142 moving anticlockwise beyond the position illustrated. The spindle 134 then drops into a recess 150 in the lever 142 and the loaded lever 136 is then lowered so that the load is transmitted to the bobbin via the bobbin engaging lever 142. The levers 136 and 142 both pivot upwardly in the package on the bobbin increases in diameter. When the bobbin is full the lever 136 is again raised and the bobbin then drops out of the lower end of the recess 150. A forwardly projecting peg may be provided on the tip 152 to prevent the bobbin dropping straight through the recess 150 when the device is first actuated to load the bobbin. The apparatus is duplicated at the other end of the frame.

Title: Improvements in or relating to fluid valves
Inventor: KRETSCHMER WILLI
IPC: F16K17/40
Filed: 1954-06-10
Abstract: 769,418. Pressure-relieving devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 13, 1955 [June 10, 1954], No. 17051/54. Class. 135. In a valve having a passage 14 leading from an inlet 15 to an outlet 18, a burster disc 19 sealing the passage and supported against the inlet fluid pressure by one operative surface 29 of a piston 24, which latter is supported by a frangible disc 26 and presents a second operative surface 31 to a second fluid pressure, the disc 26 is fractured when the sum total of the inlet and secondary fluid pressures exceeds a given value, the inlet pressure then subsequently fracturing the burster disc 19. The inlet 15 is connected to a source of kerosene under pressure whilst the second fluid is comprised by pressurized steam and oxygen generated by the catalytic dissociation of hydrogen peroxide in a combustion chamber, not shown. When the pressure on the surface 31 attains a given value, which is less than the kerosene pressure, the combined effect of both pressures fractures the aluminium disc 26 so allowing the piston to move away from the polyvinylchloride disc 19, whereupon the kerosene breaks the disc and flows to the combustion chamber. In the inoperative position shown, a ring 22, which is of the same internal diameter as the passage 14, partially supports the piston 24. The disc 26 may be replaced by a shear pin. In a modification, the kerosene and pressure steam and oxygen flow to and from the combustion chamber by separate passages, the kerosene passage including a non-return valve not shown. In another modification, the piston acts to seal the outlet when supported by the frangible disc, and the secondary source of pressure acts on the annular piston surface.

A displacement encoding scale is sensed by five photo-cells (capacitive and inductive sensing is also mentioned) to produce outputs with relative phase angles of 0, 2#/5, 4#/5, 6#/5, 8#/5,   these outputs are amplified and attenuated by factors of +1, - 1, + ¢ and the resulting signals are combined selectively (one of each phase angle but of differing amplitudes) to produce five further signals of relative phases   0,2#/5 ... 8#/5 and equal amplitude. The further   signals are squared and supplied to a logic network comprising two parts. The first part has a group of 10 output leads which are energized one at a time in sequence as the scale is displaced, the direction of the sequence depending on the sense of movement. The second part receives the output from the first part and provides a train of pulses on one of two inputs of a reversible counter depending on the sense of the displacement, there being one pulse for each movement of <SP>1</SP>/ 10  of a scale cycle. The output of the first part of the logic network may be used to illuminate spacially arranged digits.

Patent GB-850803-A (GB)
Title: Improvements in or relating to the oxide coating of glass surfaces
IPC: H01J9/20
Filed: 1957-05-30
Abstract: A coating of a metal oxide or silica on the inner surface of a glass container is produced by mixing a volatile halogen-containing compound of a metal or silicon with a gas containing oxygen or hydrogen and igniting the mixture to form a flame in a gas containing hydrogen or oxygen respectively; the resultant hydrolysis taking place in said container or in a separate reactor from which the reaction products are led to said container.  The deposition thereby takes place in the presence of hydrogen halide which improves the adhesion and other properties of the coating.  Halides specified are SiCl4, TiCl4 and SnCl4.  Preferabl the flame-forming gases are substantially pure oxygen and hydrogen.  When the reaction is performed remotely from the deposition and the oxides carried into the container by means of a tube, it is preferred to provide means to attract the oxide to the glass electrostatically.  The glass container is preferably rotated during the deposition and a flat or fishtail oxyhydrogen flame is preferred.  Suitable apparatus for the production of the flame is described in Specification 704,189, to which reference is made.

Title: Radiation thermostat control for toaster
IPC: A47J37/08
Filed: 1946-06-06
Abstract: 639,393. Electric toasters. DEHN, S. G. (Sunbeam Corporation). June 6, 1946, No. 17233. [Class 39 (iii)] [Also in Groups VI, XIII, XXXV and XXXVII] Heat supply in a toaster is cut off when the bread surface reaches a predetermined temperature by a thermostat 78 spaced from the bread slice and operated by radiant energy emitted from a large area of the bread surface ; and the thermostat comprises a bimetallic strip 78 in a housing 73 open at the front only so that the strip is subjected to heat only from the bread and is shielded from direct radiation from the heating elements when the bread is being toasted. The strip 78 actuates a switch 87 to cut off current when the bread surface reaches a certain temperature, but as the toast then cools, the switch continues the heating in a cyclic manner. When the bread is removed, radiation from an opposite heating element 65 impinges on the strip 78 and current is again supplied cyclically. The bread 43 is supported between tensioned wires 48 in a metal casing with wire-wound heating rods 65 on opposite sides of the bread. Reflectors 54 shaped so that the toast is heated evenly are held in transverse end walls and in a central transverse partition 59. The toaster has a slidably removable bottom plate 69 carrying a crumb tray 72. A lamp 93 indicates when the heaters are on. The bimetallic strip 78 is constructed in accordance with Specification 564,991, [Group XXXVII], and its ends, which are of reduced width, are held against angular movement on expansion by bolts 83. The high expansion side of the strip faces the bread so that the strip on rise of temperature moves outwardly to open contacts 87, 88 to cut off current supply. Outward movement of the strip is limited by an adjustable stop 97. The strip is mounted in a housing 73 in a reflector 54 so that its mid-portion only, which is coated with carbon, is exposed to heat from the bread surface. The housing 73 has a polished interior and focuses heat from the bread on to the strip. The strip moves by snap-action and its ends are polished, one end being slotted so that it is held adjustably by bolt 83 to vary the stress of the strip. The ends of the strip compensate for the temperature of the housing. A control knob 34 moves through links a baffle 102 pivoted on a rod 103 whereby the strip may be adjustably shielded by the baffle from radiation from the bread. A silver strip 86 connects contact 87 to a bolt 83.
Patent GB-146159-A (GB)
Title: Improved manufacture of phenolic condensation products
IPC: C08L61/10
Filed: 1920-06-24
Abstract: A moulded phenolic condensation product is made by preparing an initial mixture of an anhydrous fusible phenolic resin, a phenol, a methylene compound such as hexamethylenetetramine, and a fibrous filler such as asbestos, in suitable proportions, moulding this mixture under pressure in the cold or at higher temperature for a brief period, and converting the product, after removal from the mould, into the final hard infusible material by prolonged heat treatment. In the example, the mixture consists of specified proportions of a fusible resin prepared from cresol and hexamethylenetetramine, cresol, hexamethylenetramine, asbestos pulp, and asbestos fibre, with or without solvents such as alcohol, acetone, etc.; the mass is kneaded until homogeneous, then quickly pressed in a mould, and finally baked. The fusible resin employed may be prepared by heating excess of cresol with hexamethylenetetramine, blowing off part of the excess cresol by hot air, then adding more hexamethylenetetramine and creosote oil, cooling, and pulverizing the product. Alternatively, the fusible resin may be prepared by reaction of excess of a phenol with formaldehyde solution in the presence of a catalyst, removing the water and part of the excess phenol, and then adding hexamethylenetetramine and creosote oil as described above. Or the fusible resin may be prepared in the manner described in Specification 119,252. Instead of asbestos, other fillers such as mica, flock, wood-pulp, &c. may be used; a moulded product containing over 60 per cent of asbestos is flame-proof.  The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification of the process in which the prepared phenolic resin is omitted, and the moulding mixture is compounded of hexamethylenetetramine, cresol, asbestos pulp and fibre, with or without addition of resins, asphalt, or pitch dissolved in solvents. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 9291/14, 119,252, and 119,253.
