Title: Apparatus for the flat contact tempering of glass
IPC: C03B27/004
Filed: 1964-03-31
Abstract: An apparatus for tempering a glass sheet by contact when laid flat between a lower plate 2 (Fig. 1, not shown) and an upper plate 3 includes means for forcing a gas under pressure (e.g. air) through passageways 5 in the lower plate 2 to create a cushion of gas beneath the glass sheet 11 during the transfer of the latter on to the lower plate and before the upper plate 3 is lowered into contact with the sheet.  The lower plate 2 consists of a trued aluminium table having hollow passageways 4 for the circulation of a cooling fluid, and the passageways 5 are connected to a duct B for the passage of low pressure air, which may be heated.  The surface of plate 2 is also divided into zones by slots and grooves to permit of expansion.  Air is passed through the passageways 5, and is so directed as to assist in the movement of the sheet, during transfer of the sheet 11 on to the plate so that the sheet is not harmed by contact with the plate, after which the pressure is released until after the tempering operation. The upper plate 3, movable by a ram 10 towards plate 2, is made up of separate but contiguous components 3a forming a contact surface which is substantially plane but can deform to conform to the contour of the upper surface of the sheet 11.  The individual components 3a comprise a base 13 (Fig. 2, not shown) attached to a component 14 which is suspended from main frame 12 by a collar 18 resting on a flange of component 15 attached to frame 12, the parts 13, 14 thus being adapted to move vertically relative to part 15.  A flexible membrane 20 keeps the parts 13, 14 separated and also serves as a passage for a cooling fluid which passes against the bottom face of base 13 and out through a constricted passage 23.  Varying the pressure of tne fluid alters the pressure of the plate 3 on sheet 11. Both plates may be covered with a removable fibre-glass fabric 8 attached to a frame 9, and there may be a low coefficient of expansion metal between the fabric and the plates.

Abstract: 810,319. Lifts. MONTGOMERY ELEVATOR CO. April 30, 1956, No. 13225/56. Class 78 (3). [Also in Group XXXVII] A microswitch mounted on a lift cage is operable to cut-out the lift motors in the event of an overload in the cage, and another switch may be provided to give prior warning of an approaching overload. As shown, a switch 37, mounted on a beam 9 of a lift cage roof, is operated by movement of a lever 29 about its pivot 28, this movement being caused by a pin 40 attached to a plate 14 which can move laterally against the action of a spring 25 and to which plate the lift-supporting cables 17 are attached through springs 18. The plate 14 is connected to the beam 9 by links 16 joining bearing blocks 13, 15 on the beam and on the plate respectively, and the spring 25 is set by means of an adjustable stop 23 so that the plate 14 does not move until the load in the cage exceeds a predetermined maximum. Two switches may be operated by the lever 29, the first to operate giving an audible or visible warning and the second cutting out the lift motors.

[Class 2 (iii)] [Also in Group V] Rubber which has been partially halogenated while leaving the bulk of the double bonds free is heated with di- or poly-hydric phenols to obtain products varying from soft elastic to hard horn-like bodies. The products may be subsequently milled with substances normally used for vulcanizing or treating rubber such as sulphur, carbon, zinc oxide, accelerators, softeners &c. or with substances which form resinous compounds with phenolic compounds, e.g. formaldehyde, and the mixtures heated. In examples, brominated rubber is heated with resorcinol . or catechol. Composite bodies having a hard and soft section are formed by heating the mixture in conjunction with a rubber which vulcanizes to form a soft section at the temperature at which the mixture foims .a hard section. To facilitate adhesion, hexamethylenetetramine may be incorporated with the rubber mix. Rubber may be bonded to metal by an intermediate layer formed by milling and heating the brominated rubberphenol product with paraformaldehyde, zinc oxide, magnesium oxide, zinc stearate and anti-oxidant and then with a partially-formed phenol-formaldehyde resin, the composite product being heated in a mould for 30 minutes at 150‹ C.

Title: Improvements in the gasification of carbonaceous materials
IPC: C10J1/207
Filed: 1939-05-04
Abstract: 528,338. Gas manufacture. GAS ENGINEERS, INSTITUTION OF, DENT, F. J., and APPLETON, E. V. May 4,1939, No. 13350. CClass 55 (i)] A gas suitable for use as town gas is obtained by the gasification of weakly caking bituminous coal or coke by the action of oxygen and steam under pressure, with a high rate of gasification, to produce a gas consisting mainly of hydrogen and carbon-monoxide which are caused to react and form methane whilst the gases are still under pressure, the heat evolved by this reaction being used to preheat steam under pressure for use in the gasification. Pressures in the generator of 10 and 15 atmospheres are referred to in examples. The gas from the generator 1 passes through a cooler 2 to separate steam and tar, a washer 3 for absorbing carbon dioxide and hydrogen sulphide, and a purifier 4 for removing residual hydrogen sulphide. The purified gas passes through a reaction chamber 6 forming part of a heat exchanger 7 and containing a catalyst for this methane reaction, and the gas then passes through a washer 9 for removal of carbon dioxide, and passes by a pipe 10 to storage. Part of the generator may be byepassed through pipe 11 direct to the outlet, and part of the gas from pipe 8 may be re-circulated through the reaction chamber by pump 14. Steam from pipe 15 and oxygen from pipe 17 pass through the heat exchanger, but unheated oxygen may be supplied through pipe 16. In an example, the steam and oxygen supplied at a temperature of 300 ‹C. to the heat exchanger were further heated to 900‹C. in the latter. The concentration of carbon monoxide supplied to the reaction chamber can be controlled by the relative proportions of steam and oxygen supplied to the generator, and for further control some of the carbon monoxide may be caused to react with steam in the presence of a catalyst to produce hydrogen. Both the reaction chamber 6 and the heat exchanger 7 may be charged with the catalyst, and the steam and oxygen passed through these alternately with the generator gas in order to regenerate the exhausted catalyst. Specifications 364,407, 380,158 and 392,427 are referred to.

Filed: 1926-05-27
Abstract: 268,580. Marks, E. C. R., (Toledo Scale Co.). May 27, 1926. Computing-apparatus .-A weighing device for determining and indicating the percentage gain or loss of weight of a treated material over an untreated material of the same volume comprises a relatively movable index and chart, the latter being graduated in percentages, and a commodity receiver pivotally mounted on the scale beam and capable of adjustment to bring the index to zero position on the chart whereby a direct reading of the percentage of gain or loss in the weight of a commodity of a given size may be ascertained. In the form shown in Figs. 1 and 2, suitable for testing ice cream or similar material ,the lever 3 is connected to a pendulum 7 and to an indicating hand 8 co-operating with a chart 9. An arm 17 is pivoted on the lever 3 by means of a screw 18 and carries at one end a suspended bracket 13 for supporting a container 11. A weight 19 on the arm is adjusted to balance the empty container and associated parts about the pivot screw 18. An operating handle 21 and an indicating pointer 22 co-operating with a scale 23 are attached to the arm 17. In using the device, a definite volume of the mix or cream is placed in the container 11 and the handle 21 is adjusted to bring the indicator hand 8 to zero on the chart 9. The cream is then replaced by the same volume of aerated or frozen cream, and the reading on the chart gives the percentage of decrease compared with the weight of the first sample. In a modified device, Fig. 4, for use in determining the percentage of moisture in lumber, wool &c. a supporting grid 11<1> is substituted for the container, and the chart is marked with a number of rows 12<1> of graduations having their zero indications arranged in echelon. By this arrangement greater variation may be permitted in the weight of the test piece of lumber as any convenient row 12<1> of graduations may be selected when bringing the indicating hand to zero position with 'a moist test piece on the grid. The selected row is afterwards used to give the percentage of decrease in weight after the test piece has been dried.
