Title: Improvements in and relating to the manufacture of spectacle frames or blanks
IPC: B29D12/02
Filed: 1947-08-19
Abstract: 636,236. Moulding spectacle frames. PLASTIC FASHIONS, Ltd., RUSSELL, J. R. K., and PRASSER, A. Aug. 19, 1947, No. 22967. [Class 87 (ii)] [Also in Group XX] In the manufacture of spectacle frames from mouldable organic composition the blanks are formed without lens apertures, Fig. 1, and the apertures are cut afterwards. The eye piece portions 1 and bridge portion 2 are formed in one plane and the bridge portion subsequently bent out of that plane, under heat, to the position shown in Fig. 8. In moulding the blanks by injection moulding the composition is injected into the portion of the mould in which one of the eye pieces is formed so that it flows from that portion across the portion of the mould forming the bridge to that forming the other eye piece. Bevelling, grooving and other finishing operations complete the manufacture.

Title: An improved carburettor float
IPC: F02M1/00
Filed: 1929-07-26
Abstract: 318,241. Murphy, S. J., and Odlum, W. P. Aug. 31, 1928, [Convention date]. Spray carburettors. - A carburettor float the buoyancy of which is automatically adjusted in accordance with changes of temperature of the carburetting liquid, is divided into two compartments of which one is hermetically sealed, and the other is provided with a vent opening below the surface of and into the fuel in the float chamber. A cylindrical float c, Fig. 1, is closed at its ends by diaphragms D, E, and is divided into chambers N, K by an intermediate diaphragm F. The chamber K is sealed, but the chamber N is vented bv an annular passage O formed between tubes J, L and open at both ends. As the carburettor temperature rises, the air in the chamber N will expand and part will be expelled, rendering the float slightly more buoyant. When the engine again cools down, fuel will be drawn up the passage O into chamber N, thus decreasing the buoyancy. This process is repeated, more fuel being drawn into chamber N each time until it becomes filled. The behaviour of the float may be varied by varying the dimensions of the two chambers. The initial buoyancy of the float may be adjusted bv adding weights to a recess at its top. The chambers K, N in one form are relatively adjustable. In another form the chamber N is surrounded by the chamber K both being coaxial with the float. In still another form the chamber N is below the chamber K, and its venting passage is in the form of a siphon. An annular float is also described.

Abstract: 519,975. Loud-speakers ; microphones. STEVENS, A. H. (Brush Development Co.). Aug. 4, 1938, No. 23074. [Class 40 (iv)] A sound-transmitting or receiving device comprises a main'vibratory diaphragm and an auxiliary diaphragm which. is disposed adjacent to the main diaphragm in the. direct path of the sound waves to or from the main diaphragm, and which is so constructed and mass loaded near its centre as to have vibratory characteristics adapted'to compensate at least partially for the non-uniform response of the main diaphragm. Fig. 2 shows an example in which a microphone comprises a piezo-electric unit 2 of the type described in Specification 318,934, [Class 40 (iv)], supported at three corners on a casing 1 by pads 3 of rubber &c., the free corner being connected to the apex of a main diaphragm 4. The air space in the casing behind the diaphragm 4 is open to the outer air through a tube 8. A compensating diaphragm 9, arranged as shown, has a disc 10 of compliant material cemented to it, the disc carrying a weight 11 at its centre. The diaphragm 9 may be moulded of somewhat porous fibrous material and may be finely perforated. It may be loaded by a weight at the apex instead of the weight 11. In other arrangements, the auxiliary diaphragm may be a single flat or conical diaphragm with concentric annular weights, or a cone of varying thickness. A number of compensating diaphragms in addition to the loaded one may be provided and arranged one above another over the main diaphragm. The invention is applicable to devices operating outside the audible frequency range as well as to usual microphones and loudspeakers. The Provisional Specification also describes and shows a corrugated conical auxiliary diaphragm and an arrangement of four auxiliary cone-shaped diaphragms side by side.

Abstract: 405,358. Current and pressure meters. COLE, Ltd., E. K., Priory Crescent, Southendon-Sea, and DAWE, F. W., Franwyn, St. James's Gardens, Westeliff-on-Sea. Aug. 19, 1932, No. 23241. [Class 37.] A signal generator for use in testing radio receivers comprises a radio-frequency oscillator 4, an audio-frequency oscillator 1 and means for combining them to derive a modulated output and to indicate the degree of modulation. As shown, the low-frequency oscillator 1 feeds a transformer primary coil 2 through a potentiometer R1, and the secondary coil 3 is in series in the plate supply circuit of the radio-frequency oscillator 4. A variable series resistance R in this supply circuit serves to pre-set the oscillation amplitude. The valves 1, 4 are fed from a supply unit S. Low-frequency amplitude or percentage modulation is indicated in a meter M, and radio-frequency amplitude in a meter N. The modulated oscillations are fed to an adjustable attenuating network 9, whence they pass to a busbar 11, Fig. 2, fed also by similar generators O1-O5 operating at different radio frequencies. The busbar 11 is connected by a screened lead 12 to a distributing box 13 from which connections are taken to dummy aerials 15 feeding the receivers R to be tested. Meters 16 indicate the output of the several sets.

Filed: 1924-10-04
Abstract: 224,511. Fuller Fuel Co., (Assignees of Kaemmerling, G. H.). Nov. 6, 1923, [Convention date]. Liquid, gaseous, and pulverulent fuel furnaces. -The combustion of liquid, gaseous or pulverulent fuel is effected in a combustion chamber of small volume closed at one end and open at the other to a chamber where the heat is utilized for heating a boiler or the like, the fuel being injected with air into the combustion chamber so as to form a, number of intersecting streams producing a rotating mass of flame. The combustion chamber 10 may be rectangular in cross section, as shown in Figs. 1 and 2, or it may have any number of sides, its walls being independent of the walls of the heat-utilizing chamber 18 to facilitate renewal. Fuel and air are supplied through adjustable tubes 13 arranged in openings 14 in such a manner that the flame from one tube intersects that of an adjacent-tube. Doors 12 are provided for the removal of residues. The walls of the chamber 18 may be protected by boiler tubes and the floor 20 may incline downwardly towards the combustion chamber 10 or, according to a modification, the combustion chamber may extend upwardly above the floor of the chamber 18, the floor 20 being inclined downwardly and outwardly towards cleaning doors in the side walls. The walls of the combustion chamber may be enclosed by an outer wall, as shown in Fig. 5, forming a space 10<c> to which air under pressure is supplied and heated prior to being supplied with the fuel to the combustion chamber or through the ports 24 for secondary combustion. Instead of reducing the temperature of the combustion chamber walls by the circulation of air, the walls may be cooled by water tubes embedded therein and forming part of the water circulation system of the boiler. In a further modification, shown in Fig. 7, the combustion chamber is inverted and arranged in the roof 26 of the heat-utilizing chamber 18. Specification 1810/91 is referred to.

Abstract: 788,014. Bottling. DETREZ, R. Aug. 17, 1955 [Aug. 20, 1954], No. 23650/55. Class 125(2). In vacuum or reservoir and syphon bottling apparatus having a vacuum tube 8, a liquid supply tube 6 and a seal 4 for the bottle neck, high pressure gas is supplied to the headspace when filling is completed but before the bottle is lowered, to clear tubes 6 and 8 of liquid. As shown, the invention is applied to rotating table vacuum machines in which suction is applied to tube 8 and, when a bottle is in engagement with seal 4, liquid is drawn from a reservoir through pipe 7 to tube 6. After filling, a fixed cam 16 opens a valve 12 to allow high pressure gas to flow through pipe 14, chamber 11 and passage 9 to the headspace. In a modified form the machine, which may be of the syphon type or the vacuum type, has the liquid tube slidable on and normally closed by the vent tube and the high pressure gas is not supplied until the bottle has been lowered to an intermediate position in which the liquid tube is closed and in which the bottle neck is still in engagement with the seal 4. Specification 692,551 is referred to.
