Title: Improvements in or relating to stopper units for attachment to bottles to render thesame non-refillable
IPC: B65D49/06
Filed: 1933-09-23
Abstract: 426,130. Non-refillable bottles; delivering measured quantities of liquid. GREENE, E., 29, Laurel Place, Upper Montclair, New Jersey, U.S.A. Sept. 23, 1933, No. 26297. [Class 125 (i)] [See also Group XVIII] A stopper for a non- refillable bottle comprises a shell 1 adapted to be supported on the neck of the bottle, a buoyant valve disc 14, and a co-operating weight 15, the shell having an upwardly projecting bottom with an opening 5 therein, the rim of the opening forming a substantially flat annular valve seat with an annular gutter therearound. As shown the shell has a top flange 3 positioned on a gasket 12, and a porcelain cap 60 having lugs 111 which fit frictionally within the shell, is superimposed on the flange and gasket, the assembly being secured to the bottle by an aluminium ferrule 63 spun into the beads of the bottle neck. Resting on the weight is a guard 16 which prevents the introduction of a wire and guides the weight and disc. The contiguous faces of the weight and disc are such as to adhere under air pressure when wet. When the bottle is inverted the weight takes the disc with it, and for this purpose the contact area between the weight and disc should be greater than that between the disc and its seat 4. To facilitate escape of the liquid and minimize adhesion and friction between the shell and valve parts the shell is formed with ribs 2. The construction shown is so dimensioned that only a certain quantity, e.g. one teaspoonful, will escape at each inversion. Two modifications are described in which the part 60 is provided with a screw-cap ; in one of them part 60 is formed integral with the ferrule.

Title: Improvements in combustion control means for a steam generating plant
IPC: F23N1/02
Filed: 1924-11-10
Abstract: 224,556. Smoot, C. H. Nov. 8, 1923, [Convention date]. Regulating combustion.-In a group of interconnected steam boilers, the supply to each boiler furnace of a fixed proportion of an operative medium, such as fuel and air, is regulated automatically, the condition of such regulation is indicated at a central point and like functions influencing the output of each boiler are indicated in juxtaposition so as to show any departure in the output of one boiler from the average output of all the boilers. As shown in Fig. 1, the steam pressure in the main 9 acts upon a diaphragm 12 of the master controller 1 and operates a spring- loaded yoke 13 connected by a lever 16 to an inverted cup 19 which allows compressed air to escape from the chamber 4 to the atmosphere. the amount of leakage determining the pressure in the chamber 4. An increased load on the boiler reduces the leakage and the pressure in the chamber 4 increases and is transmitted through openings controlled by valves 21 to pressure gauges 25 and through the pipes 26 - - 29 to the various regulators one of which is shown in Fig. 2 as applied to a blower. Increase of pressure of the air on the diaphragm 47 tends to close the valve 55 and reduce leakage of steam to the atmosphere from the chamber 49 by way of the orifice 53. The increased pressure in the chamber 1 is transmitted to the piston 5 which rises and actuates the lever 58 to open the throttle valve of the blower engine. Relative movement between the piston 51 and diaphragm 47 is provided for by a dash-pot 60. The balance of the apparatus is again restored by the increased pressure in the air-supply duct leading from the blower being transmitted to the upper surface of a diaphragm 39, lever 40 and one end of a lever 42, the other end of which is acted upon by the pressure on the diaphragm 47. When the lever 58 is employed to actuate the damper in the furnace air supply conduit, the upper and lower sides of the diaphragm 39 are respectively connected to a venturi tube and Pitot tube in the air supply conduit. In the case of the stack damper, the pressure in the stack is communicated to the diaphragm 39. In a modified form of regulator applied to the engine of the mechanical stoker, the diaphragm 39 is dispensed with and balance is restored to the apparatus by an oil type governor driven by the engine and connected to the lever 42. Indicators 77, 78. Fig. 1, are employed for comparing any group of variables or functions influencing the output. Specification 179,953 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) mentions the application of the invention to furnaces fired by gas or powdered fuel. This subject-matter does not appear in the Specification as accepted.

[Also in Group XL (c)] In a direct coupled amplifier suitable for a measuring circuit, the input signal is applied between the base electrodes of a pair of transistors and the output is derived from between the collector electrodes, negative feedback being applied in dependence upon the mean collector current flowing in the two transistors. The Figure shows an amplifier of bridge form having input terminals 8, 9 and feeding a meter 10, negative feedback for the amplifier being derived from the mid-point of a potentiometer 11, 12 connected between the collector electrodes and applied to the base electrodes in series with a battery 15. At the minimum temperature of operation the bias applied through resistors 6, 7 is such that no current flows through the battery and the feedback will then maintain the collector currents constant as the temperature increases and so maintain balance of the circuit. The tapping on the potentiometer 11, 12 may be variable.
