IPC: B60J5/06
Filed: 1961-12-12
Abstract: 950,232. Door fastenings. FORD MOTOR CO. Ltd. Dec. 4, 1962 [Dec. 12, 1961], No. 44508/61. Heading E2A. A retaining device for attachment to a sliding door comprises an elongated member 10 having spaced notches 17 for co-operation with a projection 4 to retain the door in any of a series of positions the elongated member being pivotally mountable on the door and spring urged to an inoperative position clear of the projection 4 and manually movable to operative position, means being provided to fasten the member 10 in the operative position. In the construction shown the member 10 is pivotally attached to a second elongated member 7 which in turn is pivotally attached to a third elongated member 6. In use the member 6 is bolted to an inner panel 2 of the door in a depression 5 and biasing springs 9 and 13 are provided between the members 6, 7 and 10 to retain the member 10 in contact with one or more rubber buffers 14 in the depression. The pivot pin 8 between the two members 6 and 7 is welded to the member 7 so that rotation of the pin causes rotation of the member 7. The end of the pin 8 is cranked so that when it is rotated to bring the member 10 into contact with the projection 4 it becomes trapped behind a spring 15 attached to a rod 16 which operates the conventional door latch releasing mechanism. The spring 13 between the members 7 and 10 enables the member 10 to rest with its free edge in contact with the projection 4 until movement of the door allows the nearest notch 17 to engage with the projection 4 to prevent further motion of the door. The rod 8 is automatically released when the rod 16 is depressed to release the door latch and the spring 9 then rotates the members 7 and 10 until the member 10 comes into contact with the buffer or buffers 14. Pressure on the door handle then enables the door to be moved.

Title: Method of and apparatus for testing the hardness of materials
IPC: G01N3/52
Filed: 1975-10-31
Abstract: 1485218 Measuring hardness PROCEQ SA 31 Oct 1975 [7 Nov 1974.] 45554/75 Headings G1N and G1S The hardness characteristic of a material is determined by causing a test tip to be impacted with the surface of the test material and calculating the ration of the test tip velocities immediately before and after impact. As shown, Fig. 1, a test tip 1 consisting of a hard steel ball embedded in an impact mass 2 is initially drawn back from the test material 15 by virtue of the mechanical coupling between the resilient bottom portion 8 of a rod 7 and an upper bore 2a of the mass 2. The portion 8 has four longitudinal slots 8b, so that by pressing down the upper ports 10, 11 of the assembly shown the rod 7 enters and is retained in the bore 2a. The upper parts 10, 11 are then withdrawn by a spring 12 until the coneshaped upper part 9a of the portion 8 abuts against an end-face 6a of a bushing 6. This squeezes the end of portion 8 and the impact mass 2 is released to be forced by spring 5 on to the surface 15 of the test material. The mass 2 carries a permanent magnet 3 which co-operates with a coil 14 externally located at the bottom of the housing 4 to produce an output voltage which has a positive maximum just before impact and a negative maximum just after impact, these voltages being proportional to the corresponding velocities of the impact mass 2. In another embodiment the test tip is separated from the impact mass, and the maximum velocities of either are measured.

Abstract: 1,237,553. Bulked yarns. E.I. DU PONT DE NEMOURS & CO. 27 Sept., 1968 [29 Sept., 1967], No. 46033/68. Headings D1F and D1W. Bulky yarn is produced by applying mechanical crimping and heat-setting to mixed yarn comprising intermingled polyamide filaments of at least two different types (differing particularly in respect of shrinkage capacity and possibly cross-sectional form) each derived from stereoisomeric bis- (para-aminocyclohexyl) methane and its diamine homologs. The filaments are formed, and perhaps mixed, by simultaneous extrusion from different holes in the same spinneret and may be mixed subsequently in a pneumatic interlacing jet or by bundling. The crimping may be effected by false-twisting (combined with heat-setting) using a spindle or a torque jet, or by a stuffer-box crimper. Fabrics comprising at least 30% by weight of the bulky yarn may be warp or weft knit or woven. Each type of filament is constituted at least 50% by weight of repeating units according , to the formula: wherein X is 1 or 2, Y is an integer in the range of 9-14 and R represents the same or different member of the class consisting of hydrogen and methyl and S stands for saturated, at least 40% by weight of the diamine polymer constituent being of a trans-trans stereoisomeric configuration. In the bulked yarn, the two types of filament have a difference in filament length (due to filament shrinkage) of at least 5%, the "crimp index" (a measure of the amount of elongation available due to crimp) is 2-25%, and crimp frequency (based on extended length) is at least 10 crimps per inch.

Abstract: 1408606 Incinerators JOSEF MARTIN FEUERUNGSBAU GmbH 6 Oct 1972 [9 Oct 1971] 46094/72 Heading F4B In a process and apparatus for the simultaneous combustion of refuse and sewage, the refuse is fed to furnace 1, and the sewage sludge is fed through pipe 8 to an evaporator 7 where part of the water content of the sludge is removed. The evaporator 7 is heated to a temperature of 40-60 C. by steam from a boiler 5 heated by the combustion of the refuse. A reduced pressure is produced in the evaporator 7 by a venturi 12 which draws off the vapour and mixes it with the steam in line 6. The vapour and steam condense in heat exchanger 13 and are drawn off at 14. The concentrated sewage sludge is fed by a pump 9 into the furnace 1 to be burnt with the refuse on a grate 3. In a modification the sewage is concentrated in a centrifuge and only the liquid part passes to the evaporator. The concentrated sludge passes direct to the furnace. The thickened sludge leaving the evaporator may also be passed back to the centrifuge. Alternatively the sewage may be thickened in two stages, an evaporator 7 as in the form of Fig. 1 and a further evaporator in which the sludge is dried in a thin film on steam-heated surfaces. The dried sludge is scraped off and passed to the furnace. Both evaporators are connected to venturi jets to produce a low temperature. The second evaporator may have a separate steam supply from boiler 5 and the vapour produced may be added to the steam entering the heat-exchanger 13. The condensate from the heat exchanger is drawn off and any remaining vapour passed to the furnace over line 10. The dried sludge is fed to the furnace with the refuse. In the form of Fig. 5 the sewage is introduced at 8 first with a preheater 37 fed with steam at 38, it then passes over line 17 to evaporator 7 having a steam coil 13 and a vent 11 connected to the venturi 12. The vapour drawn off from the second evaporator 20 may be blown into the furnace.

Title: Sampling gas for analysis
IPC: C21C5/46
Filed: 1974-10-28
Abstract: 1500508 Sampling gases BRITISH STEEL CORP 28 Oct 1975 [28 Oct 1974] 46432/74 Heading G1B A method for the rapid transfer of gas from a sampling probe at a source of the gas to a gas analyzer remote from the gas source, comprises passing the gas from the probe along a first gas sampling duct intercommunicating with a second gas sampling duct which transfers a gas sample to the gas analyzer, the first gas sampling duct being relatively long compared with the second gas sampling duct and the gas being transferred along the first duct at a high gas transfer rate relative to the transfer rate along the second duct, a proportion of the gas in the second gas sampling duct being vented to the atmosphere immediately prior to the analysis of the remaining gas. In an example a steelmaking vessel 10 is shown with a hood 11 and an oxygen lance 12. The hood draws the hod exhaust gases into a waste gas duct 14. Waste gas sampled through the probe 15 passes at about 56 litres per minute along a first sampling duct 16 through filter 17 and cooler 18 to vacuum pump 19. In the filter fume particles are removed, and in the cooler the gas temperature is reduced to ambient temperature. Beyond the pump 19 the sampled gas continues along the duct 16 at a positive pressure until the duct leads into an analysis room 20. The duct 16 passes through the analysis room and the bulk of the sampled gas is exhausted to atmosphere at 24. A second sampling duct 25 branches from the first duct 16 within the analysis room and part of the sampled gas is drawn along the second duct 25 and through a further filter 26 at about 5 litres per minute by pump 27. From pump 27 the second sampling duct leads through a further cooler 28, to remove any residual moisture in the gas, to three gas analysers e.g. a paramagnetic oxygen analyzer 31 and infrared analyzers 32 and 33 for carbon monoxide and carbon dioxide respectively. From these analyzers the gas is exhausted through a duct 35. The analyzers 31, 32 and 33 require a gas supply rate of about one litre per minute. A bleed line 36 is provided in the second gas sampling duct 25 prior to the analyzers to vent excess gas to the atmosphere. It is possible to operate the steelmaking process with a time lag of as little as 10 to 15 seconds between sampling the waste gas and obtaining an analysis of its oxygen, carbon monoxide and carbon dioxide content. Pump 19 transfers gas at about 56 litres per minute along duct 16 at a pressure of about 22mm. mercury gauge. Duct 16 is unrestricted and of 12À7mm. internal diameter. The second gas sampling duct 25 is of 6À3 mm. internal diameter and is provided with gas from pump 27 at a pressure of approximately 60 mm. mercury gauge.
