Title: Method of and apparatus for feeding glass
IPC: C03B7/10
Filed: 1928-10-18
Abstract: 315,160. Miller, W. J. Oct. 18, 1928. Cataracts and dashpots.-In a device for feeding molten glass, the speed of travel of a plunger is varied by dashpot mechanism in which a piston or plunger reciprocates in a cylinder or a vane carried by an axial shaft oscillates in a cylindrical casing. In one construction, the cylinder 63. Fig. 5, contains an inner cylinder 64 in which the piston 66 slides, both cylinders being filled with oil. The cylinder 64 is formed with a series of outwardly-opening valves 71 and with inwardlyopening valves 73, and the motion of the piston 66 causes oil to circulate between the two cylinders. The circulation of oil is controlled by means of set-screws 73<1>, 76 which enable any valve to be kept closed or the degree to which it opens to be regulated. Modified constructions of the retarding-device are described, in one of which a rod 98, Figs. 9 and 10, with a projecting wing 102 is oscillated in an inner cylinder 103, the space between the rod and the cylinder wall being partly closed by an abutment 110 which extends inwards from the cylinder wall. Oscillation of the rod on its axis varies the spaces between the wing 102 and the abutment 110, and oil is circulated through valves 72, 74 controlled as described above. In another construction, the movement of a piston causes liquid to pass to and from a tank, the plunger being retarded by the resistance offered to the movement of the liquid through the connecting pipes.

Title: High speed turbines, for aircraft engine starters
IPC: F01D21/04
Filed: 1958-09-22
Abstract: 872,258. Turbines. BENDIX CORPORATION. Sept. 22, 1958 [Oct. 31, 1957], No. 30225/58. Class 110 (3). In a high-speed turbine for aircraft engine starters in which the turbine blades are welded to the edge of the turbine disc and have their tips adjacent the internal surface of a housing encasing the turbine, the radial faces of the bases of adjacent blades are connected by interlocking means so constructed that when one blade separates at the low strength section constituted by the weld it will be retained by both the adjacent blades as they partially separate at their low strength sections whereupon the separated and partially separated blades will rub against the inner surface of the housing to effect braking of the turbine. A gas-turbine starter for aircraft engines shown in Figs. 1 and 2 comprises a combustion chamber 11, a turbine section 13 and a reduction gear and engine-engaging section 15. The turbine section includes a housing or shroud 17 and a turbine wheel 19 with blades 36 adjacent the housing and welded as at 33, Fig. 3, to the periphery of the turbine disc 31. A cut-off means 23 responsive to the speed of the turbine normally operates on a valve control means 25 to interrupt the blow of air and fuel to the combustion chamber 11 at a predetermined speed. If the control means fails to operate, the invention prevents excessive over-speeding. The lower part of the base section of each blade has a rectangular recess 41 co-operating with a slightly smaller tongue 43 on an adjacent blade and forming a blade interlocking means. Thus, if the weld of one of the blades fractures, this blade will move radially outwardly to close the outer of two gaps 44 and will be retained by the adjacent blades, causing the welds of the adjacent blades to fracture allowing the separated blades to rub against the housing and causing a braking of the turbine wheel. In an embodiment (not shown) the interlocking means comprises a circular pin which loosely engages two opposed semi-circular grooves in the facing base sides of the blades.

Filed: 1976-07-21
Abstract: 1494985 Moulding sliding clasp fasteners OPTI PATENT-FORSCHUNG. UND FABRIKATIONS AG 21 July 1976 [22 July 1975] 30357/76 A row of sliding clasp fastener members is made by feeding cold thermoplastics strip to mould cavities defined between co-operating rotating forming tools and subjecting the strip to ultrasonic energy to soften it to facilitate moulding. In a first embodiment, Figs. 1 and 2, a central forming roll 19 having peripheral cavities 21 is engaged by four outer forming rolls 20 each of which is provided with cavities 21 co-operating with those of the central roll. The rolls are synchronously driven from a motor 17 by a belt 18 and a gear train 14, 15, 16 and the central roll is connected to an ultrasonic generator 24. Plastic strip material is passed between each outer roll and the central roll to form the sliding clasp fastener members. It is preferred for the forming tools to be provided with co-operating circumferential grooves 23 which co-operate to form a strip from which the fastener member 22 project in tooth-like fashion. A pair of plastics strips sandwiching a carrier tape 28 may be passed between the tools to form a fastener strip provided by a carrier tape. In variations of the first embodiment, the central roll may co-operate with only two (Fig. 4, not shown) or three (Fig. 5 not shown), outer rolls. In a second embodiment, Fig. 7 the central and outer rolls 30 are provided with co-operating cavities 22 as before but the central roll is not connected to an ultrasonic generator. Rather a separate ultrasonically vibrated tool 33 projects into the recess 31 defined by the peripheral grooves of the rolls. The tool forms a groove in the resultant fastener strip into which a carrier tape may be bonded. In a third embodiment, Figs. 9 and 10, a pair of annular discs 35, 36 carry peripheral cavities 22 and are distorted into co-operation in a moulding region 39 by lower rolls 40 and guides 43 and are distorted out of co-operation in an ejection region by upper rolls 40. The discs are driven in unison by a lower drive gear 42 and guiding is aided by a pair of upper idle gears 41. In the moulding region the cavities 22 co-operate with an ultrasonic tool 44. In a variation of the third embodiment the annular discs may be replaced by cavitied conical discs, the sloping faces of which co-operate to define a moulding area. In all embodiments the cavities in the tools may be slightly circumferentially offset to provide members having locking shoulders.

Filed: 1926-12-01
Abstract: 291,475. Freeman, N. H. Dec. 1, 1926. Mineral and tar oils, extracting. -Oil is obtained from shales, coals, and like oil-bearing minerals by heating them to and maintaining them at a predetermined critical temperature until substantially the whole of the hydrocarbon content is soluble in a hydrocarbon oil, as described in Specification 248,014, and removing the oil in a heated entraining agent e.g. superheated steam, gas, or oil vapour. Normally, a critical temperature of about 300‹ C. maintained for about 1 hour is satisfactory. When treating bodies yielding more than say 80 gallons of oil per ton the vapour of the oil exuded and made evident by the preliminary heating may be the entraining agent, distillation being continued up to about 400‹ C. Using the apparatus shown, shale is passed with continuous agitation through a retort or heater a, e.g, of the kind described in Specification 124,015, [Class 55 (i), Coking &c.], having a series of heating chambers connected to separate condensers b, the critical temperature and the duration of treatment being determined by a preliminary test. The heated shale is conveyed through a box f to rotating extraction retort h provided with a stirring and feeding device i and heating means such as a gas flue j, and is treated with steam at 360-400‹ C. admitted from a boiler r by a pipe k. The vapours and steam pass by a pipe m to a condenser n, ash &c. is fed to the end box l and discharged to a conveyer o and a dump p. The conveyers g, o serve as sealing devices for the retort h once they are in operation, dumpers q being used when starting.

Abstract: 815,714. Seats. LORENZ, A. Oct. 25, 1955 [Nov. 5, 1954], No. 30458/55. Class 52(2) In a reclining chair having a back rest and seat structure rockably mounted on a support and a leg-rest extended automatically as the structure is rocked rearwardly the leg-rest is actuated by a lazytong linkage one inner end of which is pivoted to the support and the other inner end of which is actuated by the structure. As shown in Fig. 1, the lazy-tongs consist of two pairs of links 40, 44 and 32, 30. The latter pair carries the leg-rest 52 on a pivot 56 and a pivoted link 60. The inner ends of links 40, 44 are pivoted respectively to the support 10 at 42 and to a downward extension 20 of the back rest 16 at 46. Tilting back of the back rest 16 causes link 44 to swing link 40 about pivot 42 whereupon a link 48 moves the seat 22 and the lazy-tong linkage extends the leg-rest. As shown in Fig. 2 (not shown), the seat is raised by an upward extension of link 32. In a further modification, Fig. 3 (not shown), the seat is raised by a link pivoted both to the front of the seat and to the forward part of link 30. As shown in Fig. 4, the lazy-tong linkage consists of pairs of links 340, 344 and 332, 330 and is pivoted to the support at 342. The inner end of link 344 is pivoted at 372 to the foot of link 374 pivoted at 376 to the support. The back rest and seat are formed as an integral unit 368 pivoted to the support at 370 and, when tilted rearwards, a downward extension 384 thereof, acting through a link 378, swings the link 374 and actuates the lazy-tongs to extend the leg-rest. In a modification, Fig. 5 (not shown), the back rest and seat unit is pivoted at the foot of extension 384 to the support and a link and bell crank actuate the lazy-tong linkage. In a further modification, Fig. 6 (not shown), the rear part of the back rest and seat unit merely bears on one end of a bell crank, the other arm of which actuates the lazy-tong linkage. Stops may be provided to limit the pivoting in the sitting and reclining positions, and means may be provided for locking the parts in adjusted position. Specification 815,713 is referred to.

Title: A process for the production of modified urea-formaldehyde resins
IPC: C08G12/04
Filed: 1950-12-14
Abstract: Urea-formaldehyde resins are modified with carbamic acid esters containing free hydroxyl groups.  The ester may be made by fusing excess of urea with a polyhydric alcohol at about 170-180 DEG  C., the degree of esterification being estimated by following the evolution of ammonia.  The reaction product is then reacted with formaldehyde.  Preferably less than two mols. formaldehyde are used for each mol. of total urea (i.e. free urea plus urea combined in the ester) and preferably 2-4 mols. of free urea, 1 mol. carbamic acid ester and 4-8 mols. formaldehyde are used. These proportions give water-soluble products suitable as adhesives and impregnants for textiles and paper.  The preferred pH for the formaldehyde condensation is 3-6, the reaction product being adjusted to pH 7.  In a modification, a water-soluble condensate of urea and formaldehyde (e.g. methylol urea) is reacted with the carbamic acid ester.  In examples: (1) 3 mols. urea were fused at 175 DEG  C. with rather more than one mol. pentaerythritol and after the evolution of approximately two mols. ammonia the reaction product was boiled at pH 3-3.5 with formalin containing 8 mols. formaldehyde to give, after adjusting the pH to 7, a clear, stable solution hardenable with acids; (2) similar to (1); (3) similar to (1) using glycerol; (4) similar to (1) using a dimethylol urea solution instead of formalin.ALSO:Carbamic acid esters containing at least one free hydroxyl group are made by fusing urea with a polyhydric alcohol, preferably at about 170-180 DEG  C.  The degree of esterification of the alcohol can be estimated by following the evolution of ammonia. In examples: (1) to (4) esters are prepared from urea and pentaerythritol and from urea and glycerol by heating at about 175 DEG  C., various quantities of ammonia being liberated.  The products are used as modifiers for urea-formaldehyde resins (see Group IV (a)).
