Title: Improvements in and relating to bottles
Inventor: WITTERSHEIM ADAM
IPC: G01F11/26
Filed: 1968-07-03
Abstract: 1,220,416. Compressible bottle and dispenser container; container closures. GOLDWELL G.m.b.H. CHEMISCHE FABRIK H. E. DOTTER. 3 July, 1968 [5 July, 1967; 3 May, 1968], No. 31779/68. Headings B8D and B8T. A storage bottle 1 for filling a dispensing container 7, wherein the bottle along at least part of its axial length is in the form of a compressible bellows 2 which, when an axial compression is applied to the bottle, causes liquid, e.g. a hair cosmetic, in the bottle to transfer through a take-off tube 6 in the bottle to the container. A cap or stopper 4 is inserted into the mouth 3 of the bottle, clinging in airtight fashion to the inner wall surface of the mouth and having a flange 5 overlapping the edge of the mouth. The take-off tube proceeds from an aperture 15 in the base of the stopper. A cavity in the stopper has two diametrically opposite projections 14 extending inwardly from the wall and accommodates the neck and closure cap 8 of the dispensing container 7. The head 9 of the closure cap has an axial bore 10 constituting a passage duct through which the container is filled and emptied. A substantially cylindrical sleeve 13 is drawn over the head and covers an air passage aperture 12 communicating with an air tube 11. When the head of the container is inserted into the cavity in the stopper of the bottle the sleeve is compressed laterally by the projections to assume an elliptical cross-section whereby the air passage aperture is exposed. If the dispensing container is then forced down, the bellows compress and liquid is forced up through the tube 6 and into the container, while air passes down tube 11 and escapes through aperture 12. Any excess liquid is forced down the air tube, collects in the cavity and flows back into the bottle through the aperture 15 after removal of the container. A screw cap with an inserted sealing disc may be affixed on to the externally threaded neck. The projections in the stopper may be made to embrace and retain (Fig. 2, not shown) the head of the dispensing container and a cover 17 provided to seat on a shoulder 18 immediately below the bellows. More than two projections may be formed, symmetrically disposed in the cavity of the stopper. The bottle and take-off tube may be made of a plastics material.

Title: Improvements in brakes with one or more brake shoes which can be pressed against theside of a cylindrical brake drum
IPC: F16D65/08
Filed: 1934-11-05
Abstract: 437,849. Drum brakes. SCHRODER, H., 27, Amagertorv, Copenhagen. Nov. 5, 1934, No. 31799. [Class 103 (i)] To avoid irregularity of wear of a brake shoe lining, the surface of the brake shoe facing the brake drum is shaped so that the brake lining when just filling the space between the brake shoe and the brake drum decreases in thickness towards each end. The curved surface A, B, D of the shoe 6 may have the same radius as the inner cylindrical surface of the brake drum 5. The variation in thickness of the lining may approximately follow the shape of a cosinusoid. The varying thickness of the lining may be calculated approximately from the equation tv = t cos v where t is the thickness at the thickest part and tv the thickness at any angle v taken from this part and the centre of the brake drum.

Abstract: 186,885. Viel, L. L. Oct. 3, 1921, [Convention date]. Spray carburettors.-A mixture richer than that normally used is produced by causing the throttle valve, after it has reached its fully open position, to actuate a member which restricts the flow of air to the interior of the fuel-nozzle, such air flow tending normally to reduce the flow of fuel. The fuel nozzle A fed from the float chamber B discharges through calibrated holes T and an annular orifice S into a restricted part E of the induction pipe F provided with a throttle valve H. Air is admitted to the interior of the nozzle through a conduit C provided with a valve 0, a permanent opening D, and an inlet M adapted to be controlled by a valve K loaded by a spring L and actuated at the fully-open position of the throttle valve by an arm I thereon. A slow-running nozzle X discharges into a pipe Y having a valve Z and entering the induction pipe above the throttle valve. The valve K may be actuated from the throttle indirectly by the accelerating pedal or lever. The spring L forms an elastic stop or division between the phase of normal running and that of running with the rich mixture.

Abstract: 493,041. Capacitance measurements; determining physical qualities of materials ; valve relay circuits. SHARLAND, L. A., and KENWELL RADIO, Ltd. Feb. 27, 1937, Nos. 32760/36, 12422/37, and 15647/37. [Class 37] [Also in Group XL] Apparatus for detecting the presence of foreign substances in air comprises two oscillators, one at least of which has associated with it a condenser exposed to the air to be tested, the oscillators being screened from one another and coupled in different ways to feed a valve which is screened from the oscillators. Changes in the amplitude or frequency of the anode current of this valve indicate the presence of gases &c. in the air by actuating a relay, indicator, or warning device. As shown in Fig. 1, one oscillator comprises a valve V1 having a grid coil LIG, and an anode coil LIA, in parallel with which is a variable condenser VC and a condenser DC influenced by the air to be tested. The valve of the second oscillator is formed by the triode section V2 of a multielectrode valve V2, V3, the anode coil L2A being tuned by a. fixed condenser FC. A coil LIC coupled to the coils LIA, LIG, picks up the oscillations of the first oscillator and transmits them to the control grid of the valve section V3. Oscillations from the second oscillator are fed to the valve section V3 by a connection within the multi-electrode valve between the control grid of the section V2 and the auxiliary grid of the section V3 interposed between screen grids. The frequency or amplitude, or both, of the anode current through the valve section V3 are determined by the feed from both oscillators, one feed being inductive and the other electronic. The anode of the valve section V3 is coupled to valves V4, V5 so as to actuate a relay RL and thereby give an indication or alarm. The condenser VC is adjusted so that under normal conditions the frequency of both oscillators is the same, the occurrence of any change in the air between the plates of the condenser DC causing a change in the anode current of the valve section V3 and thereby actuating the relay RL. In a modification, Fig. 2, the first oscillator comprises two valves V1, V2, and the second oscillator comprises a valve V3 and the triode section V4 4 of a multi-electrode valve V4, V5. The valve V2 is of the variablegain type, with a potentiometer resistance P for adjusting the gain. The oscillators are screened from one another and from the valve or valve section fed thereby, the screens being indicated in broken lines in Figs. 1 and 2. Air may be conveyed to the condenser DC by means of a small pump or impeller. Specification 405,598 is referred to.
