Title: Improvements in or relating to sliding clasp fasteners
IPC: A44B19/26
Filed: 1941-03-06
Abstract: 548,452. Sliding-clasp fasteners. SAMSTEGMAN, E. March 6, 1941, No. 3080. [Class 44] In a sliding clasp fastener the slider of which has guard members serving to prevent the contents of a bag &c. or material lying beneath the fastener from becoming engaged in the fastener elements, that end of the slider c which leads in the opening movement has a downwardly bent guard e serving to depress the fastener elements a together with the contents of the bag &c. below the entrance level at that end of the slider. The other end of the slider may have a guard g which may be downwardly bent, as in Fig. 1, but preferably is upwardly bent as in Fig. 9. Figs. 1, 2 shown the guard g provided with a cross-bar f spanning the gap between the opened stringers. A similar bar h may be provided on the upper plate of the slider. The ends of the bars are rounded, or alternatively, the ends of bar h may be downwardly bent to limit lateral separation of the stringer by engagement with the fastener members. The edges of the lower plate of the slider at the left as seen in Fig. 1 taper to a point, not shown, disposed on the central line of the engaged elements. In a modification guards e, f are integrally joined by a bridge-piece extending over the upper plate of the slider and serving to receive the usual operating tab. In another modification the cross-bar f is replaced by an elongated wire loop placed with its greater dimension transverse with respect to the length of the stringer. Fig. 9 embodies this modification and shows one long side of the loop anchored in the curled end of guard g, its other long side contacting the lower surface of the slider. Fig. 9 also shows a slider locking device comprising a member o pivoted at p and biased by spring r so that a projection q is urged into engagement between consecutive elements a. A V-form member t has one limb slidable on the upper slider plate, an arm on the end of this limb engaging at s under member o which is raised to release position when member t is moved to the left by tab d engaging the other limb, which is of channel section to slidably embrace the wire bridge-piece i, thus preventing lateral displacement of member t. Tab d is a wire link bent as shown to rest snugly against guard e.

Title: Improvements in or relating to gas turbines
Filed: 1942-03-09
Abstract: 573,783. Gas turbines. SOC. RATEAU. March 9, 1942, No. 3098. Convention date, March 10, 1941. [Class 110 (iii)] A useful output turbine Tm and an auxiliary turbine Ta driving a compressor C are supplied with gases from a combustion chamber Ch, and the temperature of the gases after leaving the first stage moving blades is maintained constant, or within a pre-determined temperature range. One or more compressors, with or. without intercooling ; and one or more auxiliary turbines with or without inter-heating may be used, and the plant includes two or more shafts. To lower the temperature of the gases after the first stage of Tm a valve O<1> is closed and a valve O<2> opened to speed up the turbine Ta and supply more air from C. A speed governor R<1>, or other regulator, controls the supply of fuel to a burner b, and a thermostat t<1> regulates the temperature at the required point by opening valve O<1> and closing valve O<2> (or vice versa) simultaneously. The turbines Tm and Ta may be in series. The thermostat t<1> may act on a single valve in a passage bypassing Tm. Either turbine may be the highpressure turbine. In Fig. 5 control is obtained by using an electric, hydraulic or pneumatic generator G which supplies a motor M on the shaft of Ta through a regulator controlled by t<1>. On a temperature rise at the first stage in Tm, the generator G speeds up the motor M and more air is supplied by C. In Fig. 6 a governor R<1> acts on a burner b, and a governor R<2> on one end of a balance-lever p, the other end of which is controlled by t<1>. In a further arrangement, Fig. 7, the compressor C supplies two combustion chambers, one for each turbine. A burner b<2> is controlled by a balance lever p<2> coupled to R<2> through a further lever p<1>2, and R<1> acts on b<1> and the other end of p2. In a modified arrangement one combustion chamber supplies branches leading to the two turbines, a thermostat t<1>, controls O<1> and O<2> and a valve in a passage leading compressed air to the turbine Ta is controlled by a balance lever p<1>2 functioning as in Fig. 7.

Title: Improvements relating to the manufacture of hollow articles
Inventor: RAWSON HAROLD
IPC: C03B9/36
Filed: 1963-01-25
Abstract: <PICT:0989662/C1/1> <PICT:0989662/C1/2> Hollow glass articles closed at one end are manufactured by cohesively engaging the underside of viscous glass overlying an apertured support surface with a drawing head which is then moved downwards drawing the glass with it to form the closed-ended article beneath the aperture, after which the drawing head is detached and the article trimmed from the unwanted glass when the article is cool. Viscous glass 3 either as a sheet or ribbon, or as a circular disc, overlies an aperture 2 in a support 1. A drawing head 5 is moved into contact with the underside of the glass in the aperture and is then drawn downwardly to form a hollow article 6 closed at one end. The adhesion of the head 5 may be aided by the use of suction, or by chromium plating, to which glass does not stick when cool.  A blowing head 9 may be used to assist in the control of the article thickness.  Forced cooling 8 may also be used to help control the wall thickness. When finally drawn and cool the article is severed from the unwanted glass, as at 7, and the head 5 removed.  The sheet 2 may overlie a plurality of apertures to enable more than one article to be formed simultaneously.

Title: Method of distilling vinyltoluene
IPC: C07C15/46
Filed: 1957-01-30
Abstract: Vinyltoluene is separated from the reaction products of the thermal dehydrogenation of ethylbenzene by submitting the reaction products to fractional distillation in the presence of a small proportion (e.g. 0.01 to 0.1 per cent) of 2-nitrophenol or 2-nitrothiophene or a mixture thereof to inhibit the formation of polymeric material.  The purified vinyltoluene is obtained as distillate, while divinylbenzene and the inhibitor are retained in the distillation residues.  In an example, a vinyltoluene feedstock containing 0.5 per cent of divinylbenzene, to which 0.2 per cent of dinitrocresol had been added, was fed through inlet 2 into the reboiler 1 of a column 4, which was 26 feet long and was filled with ceramic saddles.  The upper part of the column was connected to condenser 6, receiver 8, distillate-withdrawal pipe 11, and reflux <PICT:0795650/III/1> return pipes 9, 14.  The fractionation was carried out at an absolute pressure of 85 to 95 mm., employing a reflux ratio of 3 : 1, while feeding 2-nitrophenol dissolved in a small amount of the reflux from vessel 12 into the column at a point 8 feet below the top in an amount corresponding to 0.04 per cent by weight of the feedstock supplied to the reboiler.  The distillation was carried out continuously over a period of 31 days without any apparent formation of polymer in the apparatus.

Title: Improvements in thermionic valve installations
IPC: H04B1/16
Filed: 1924-02-11
Abstract: 211,160. Depriester, R. Feb. 10, 1923, [Convention date]. Thermionic amplifiers and oscillation generators.-In order to prevent whistling in valve circuits in which an alternating current supply is used for heating the filament and for energizing. the plate, the impedance of the external portion of the grid-filament circuit, at the frequency of the supply, is reduced as far as possible, and negative polarization is applied to the grid. The circuit may be employed as a generator for medical or other purposes, as a signal receiver, or as an amplifier of continuous currents. The Figure shows a pair of valves A@ A2, with an input transformer TE, an inter-valve transformer T, and an output transformer TR supplying a telephone receiver O. The filaments of the valves are connected in parallel across the secondary of a supply transformer Tc through a control rheostat r1. High tension is applied to the valve plates by a supply transformer TF through a rectifying valve F and smoothing condensers and inductances L. The filament of the rectifying valve is fed through a transformer Tc and rheostat r2. The plate filament circuits are completed through a resistance R, shunted by a condenser C to approximately the mid-point of a resistance connected across the filament terminals. The resistance R is also in the grid circuits of the valves, so that the flow of direct current in the plate circuit gives a. negative bias to the grids. The back-coupling effect of the resistance R is eliminated by the shunt condenser C which has low impedance to the variable amplified currents. The impedance of the grid circuit to currents of the supply frequency is reduced by the condenser C and by employing an input transformer of thick wire with small magnetic leakage. Specification 209,184 is referred to. Reference has been directed by the Comptroller to Specification 186,069.
