Filed: 1946-12-23
Abstract: 623,098. Exhaust-silencers. DEHN, S. G. (Fluor Corporation, Ltd.). Dec. 23, 1946, No. 37757. [Class 7 (ii)] In an internal combustion engine silencer for dampening pulsations produced in an exhaust gas stream, there is provided a pair of relatively large pulsation-absorbing chambers through which the gas flows in series, and a circular cross-section conduit forming an acoustical inductance passage interconnecting the chambers, the minimum volume of each of the chambers and the dimensions of the passage having predetermined values substantially in accordance with the following equation : LV/R<SP>2</SP> C<SP>2</SP>/78.674F<SP>2</SP> wherein L=Length of the passage in inches R=Radius of the passage in inches. V=Minimum corresponding or common volume of the chambers in cubic inches. C=Velocity in feet per minute of sound in the gas. F=A selected value for the fundamental frequency per second of pulsations created in the gas stream. A cylindrical casing 11, Fig. 1, is divided by a transverse partition 12 into two chambers 13, 14 interconnected by one or more conduits 18. The exhaust gas enters the chamber 13 by an inlet pipe 15 and discharges from the chamber 14 by an outlet pipe 16, after taking a sinuous path. The casing 11 may be contained within an air jacket 21, the air being drawn through a space 22 by the induction action of the gases discharging from the outlet pipe 16. In a modification, Fig. 3, a centrally-disposed air conduit 34 extends throughout the length of the casing 30, whilst an exhaust inlet pipe 38, which is positioned within the conduit 34, has its other end situated in the wall of the latter to enable the exhaust gas to discharge opposite a baffle 46 into a lefthand chamber 31. The latter is formed in the cylindrical casing by a central transverse partition 33, from which by means of interconnecting conduits 45 disposed externally of conduit 34 the exhaust is led into the second chamber 32. The walls of the central air conduit 34 have two diametrically opposed openings in the second chamber 32 which by means of piping communicate with a common exhaust outlet pipe 42 located within the right hand end of central air conduit 34. The outer end of the exhaust outlet pipe 42 discharges into a venturi 36, that is a continuation of the central air conduit 34, wherein the air and exhaust gas are discharged together. In a further modification, the casing 30 is enclosed in an air jacket through which air travels from the outlet side of the silencer before being admitted into the central air conduit 34 near the inlet of the latter into the casing 30. Under these circumstances the main air inlet to conduit 34 may be c'osed.

Patent GB-1032137-A (GB)
Title: Improved energy-conducting devices and methods of manufacturing same
IPC: C03B37/15
Filed: 1964-09-21
Abstract: A method of manufacturing a fused energy-conducting structure comprising placing a number of long and thin glass clad energy-conducting elements longitudinally in a glass tube having one end closed, applying fluid pressure externally upon said tube and heating the combination of tube and elements to a temperature sufficient to fuse the glass claddings of the elements together, is characterized in that the combination is heated progressively along its length from the closed end to the open end so that the fluid pressure causes the tube to progressively collapse and compress the elements sufficient to close any interstices therebetween. Fibres of glass of a relatively high refractive index having a cladding of glass of relatively low refractive index, are placed within a glass tube 28 (Fig. 6, not shown) closed at one end such that they come less than half-way along the length of the tube.  This combination is then suspended vertically in a furnace 34 with the open end 32 depending.  To prevent collapse of tube 28 and also support the fibres a rigid tube 36, of stainless steel, is placed inside tube 28, with a foraminous screen 46 below the fibres. The open end 32 of the tube 28 is hermetically sealed to the furnace.  The furnace is heated up to a temperature below the glass fusion point so that any organic matter may be oxidized and gases drawn off from the fibres, oxygen being first passed into the tube 28 and then the whole evacuated. During evacuation the temperature is increased to about 1100 DEG  F. and simultaneously vacuum is applied to the chamber 105 of the furnace in which the combination is suspended.  The glass tube 28 with its fibres is then cooled a little.  A travelling heater 150 having heating coils 152 mounted for vertical longitudinal movement in the chamber 105 is then passed progressively along the length of the inhibited by the addition of a small quantity (less than stoichiometric) of the said phosphonic acid.

Title: Type lever mechanism for power-driven keyboard-operated office machines
IPC: B41J23/12
Filed: 1960-11-09
Abstract: 969,208. Typewriters. M. GRUNDIG, [trading as GRUNDIG ELEKTRO-MECHANISCHE VERSUCHSANSTALT]. Nov. 9, 1960 [Jan. 12, 1960], No. 38481/60. Heading B6F. Power-roller type-actions.-A type-lever mechanism comprises a key-lever 1, a release pawl 5 and a friction shoe 15 pivotally mounted on an intermediate lever 14 and capable of single or continuous type action. The release pawl 5 has three contact surfaces, the first, surface 9, contacts an adjustably mounted stop 9 when the key is in unoperated position, the second, surface 10, brings the friction shoe 15 into engagement with its driving roller 26 and, the third, surface 11, serves as a stop for the intermediate lever 14 by which the pawl 5 is displaced off a contact bar 20. When the keylever is depressed a pin 4 causes the pawl 5 to contact the bar 20 and surface 10 to initiate action by tilting the shoe 15. At the end of the action 12 is determined by the adjustable eccentric 25 engaging the end 12 of the friction shoe lever. The nose 22 of the intermediate lever 14 at this time moves the pawl 5 so the lug 19 slides over the bar 20. In this position no continuous actions can take place. For continuous action the key-lever is depressed deeper, and although the lug 19 is still behind the bar 20 the deeper depression causes the bent end 12 of friction shoe lever to strike against the depressed contact surface 10 so that the shoe 15 immediately lies again on the power-roller 26 to effect a repeat action. Adjustable impact, letter-by-letter.-Adjustment of the eccentric 25 determines the knockoff time of the shoe 15 so each type-lever has a required impact. Touch control.-This is controlled by vertical adjustment of either or both upper stop 8 and control bar 20 which are attached to the typewriter framework by slotted angle pieces. Further the lugs 3 may be adjusted by means of a tool. Key construction.-The key-levers 1 may be constructed so one pattern will suit all rows: a number of separate pivot holes 4 is provided, one for each row of keys.

Title: Apparatus for enabling close tolerance punching with a reusable type punching system
IPC: B21D28/26
Filed: 1977-09-20
Abstract: The tool is a combination of a pillar die set and a guided punch. The alignment of the punches (54) to the dies (44) is to be more accurate than hitherto, without a significant increase in costs. The previous alignment tolerance of +/- 0.13 mm is to be reduced to 0.025 mm. Use is made of a free-hanging pendulous guide plate (16), which lies between the punches and the die plate (14) carrying the dies. By means of the guide plate (16), the punch tips (76) are guided vertically and horizontally. The guide plate (16) and the die plate (14) are provided with pilots (94) which align the guide plate and the die plate relative to one another. The thickness of the guide plate is independent of the thickness of the workpiece (18) to be punched and need no longer be thick or of multi-layer design. In order to achieve this, rubber-elastic stripper sleeves (60, 138) are used with the punches (54) and pilots (94), these being compressed during the punching operation. <IMAGE>

Abstract: 1,149,648. Sterilising particulate materials. MERCK & CO. Inc. 5 Sept., 1966 [7 Sept., 1965], No. 39536/66. Headings A5B and ASG. particulate water-insoluble solid medicinal materials are sterilised by suspending them in an aqueous saturated solution of sodium chloride containing excess undissolved sodium chloride, heating the suspension to a temperature above 100‹C, and maintaining this temperature until sterilisation is effected, the excess of sodium chloride being sufficient to maintain saturation at the said temperature. Heating is preferably at 110‹ to 130‹C at elevated pressure, (e.g. by autoclaving); the sodium chloride may be present in 10% excess of the amount needed to form a saturated solution at 100‹C. The process is especially directed to sterilising steroids, such as dexamethasone or its phosphate, acetate or tertiary butyl-acetate, hydrocortisone, methyl prednisolone acetate, betamethasone acetate, and triamcinolone acetonide, but may also be used for any non- electrolyte salts or salt formers, e.g. indomethacin and thiobendazole. The aqueous suspension preferably includes a surface active agent, e.g. polyoxyethylene sorbitan monolaurate. Sterile compositions for parenteral use or opthalmic application are prepared, which contain in addition to one or more of the aforesaid ingredients, one or more suspending agents, e.g. sodium carboxymethyl cellulose, hydroxyethyl cellulose or sorbitol; chelating agents, e.g. N, - ethylene - diamine - tetra - acetate; preservatives, e.g. Na. - bisulphite or benzalkonium chloride; lecithin; creatinine; phenethyl alcohol; benzyl alcohol; and lidocaine. The process is useful for sterilizing drugs of pre-determined particle size, and is said not to cause alteration of the particle size.

Comprises inner and outer layers 1 and 3 and at least one intermediate layer 2, having different combustion rates. A chamber defined by the inner layer presents a continuous smoothly curved ignition surface Z and communicates with atmosphere through an exhaust nozzle 5. The interfaces and the outer face B are shaped similarly to the surface 2. The arrangement is such that the combustion frontier advances smoothly through the layers and is transferred gradually from one layer to the next whilst reaching the outer limiting surface B simultaneously at all points. As shown in a spherical arrangement, the interfaces are eccentrically offset from the surface Z and outer face B which are concentric. The layers are of progressively decreasing burning rate. The combustion frontier is transferred from layer to layer at the points 6 and 8 so that the thrust drops until the preceding layer is exhausted, whereafter the thrust increases in the fully burning layer as the square power of the radius of the frontier. In a second embodiment the interfaces are ellipsoidal and offset from spherical ignition and outer faces which are concentric. In one modification the interfaces are ellipsoidal without being offset and with their major axes at right angles. In another modification without offset all the surfaces and interfaces are ellipsoidal.
