Title: Process and apparatus for detoxicating exhaust gases
IPC: F02C6/12
Filed: 1971-05-03
Abstract: 1325666 Treating I C engine exhaust gases; exhaust gas turbo-chargers KUHNLE KOPP & KAUSCH A G 3 May 1971 [2 May 1970 8 July 1970 (2)] 12805/71 Heading F1B and F1G Combustible CO and CH compounds in the exhaust gas from an I.C. engine are eliminated by passing the gas into a twist generator to cause the gas to expand, then into a diffuser at a pressure below atmospheric which causes combustion air to be sucked in, raising the pressure of the air-gas mixture and causing combustion thereof. An apparatus for carrying out the process comprises a twist generator 101 which is directly attached to the exhaust line by a flange 105 and which has guide vanes 116 which cause the gas to swirl. The cross-sectional area of the outlet 109 from the twist generator is controlled by the position of an axially displaceable hollow regulator 106 so that the depression at the outlet 109 causes combustion air 108 entering the interior of the regulator to be sucked out through slots 107 at its periphery. The mixture passes into a diffuser 102 with a strong swirl and is burnt therein. The combustion air is pre-heated by passing it through a heat-exchanger which encloses part of the exhaust manifold. In an alternative construction, Fig. 5, the guide vanes 116 are replaced by a turbine 5, which drives a super charger. Part of the air compressed by the super charger is bled off and enters a port 7a in a casing surrounding the diffuser 4, where it is preheated before entering ports 8a and passing via apertures 13, through the regulator 6 to emerge at the peripheral slots 19, where it mixes with the gas exhausted from the turbine through the variable area aperture 15. The combustion air may also enter through a chamber 16, in which case it helps to cool the turbine.

Abstract: 112,029. Mitchell, E. A. Sept. 11, 1916. Stuffing-box joints; sleeve joints. -Relates to pipe joints of the type in which the ends of the pipes a, b ara held in alinement in a sleeve c with enlarged ends c', and in which tight joints are effected by means of packing-rings d compressed in the enlargements c<1> by gland-like sleeves f slidable on the pipes and drawn together by bolts h. According to the invention, after the sleeves f have been drawn together, they are firmly secured to the pipes in order to prevent relative endlong movement of the pipes by means of set-screws k passing through threaded bosses on the sleeves and bearing directly on the pipes. Modifications are described in which the packing-rings d are located in enlargements at the ends of the sleeves f only, or both in enlargements at the ends of the sleeve c and in recesses at the ends of the sleeves f. The rigid bolts h may be replaced by a flexible connexion, such as a chain, a hook and eye connexion, or a link connexion in which the links are permitted relative movement to each other.

Title: Drilling machine
IPC: B23B41/00
Filed: 1944-07-06
Abstract: 585,045. Drilling-machines. PRIEST, C. H. July. 6, 1944, No. 12941. [Classes 83 (ii) and 83 (iii)] Making screws.-In a machine for cross-drilling the heads of slotted screws to receive a locking-wire, the screw is clamped by means of its slot in an adjustable jig-bush and is ejected by compressed air that also removes the cuttings. The jig consists of a bush 10 with a part flange 17 provided with a number of radial holes 18 brought in turn into line with the drill 6 as the previous hole becomes worn. The bush is held in the split end of a slide 5 by a screw 8, and it is tapped to receive an exchangeable work-holding bush 14 drilled according to the screw size and adjustable by a screw-driver slot 16 to bring the screw head into correct relation to the drill. The slide 5 moves in guides on the top flange 19 of an I-beam forming the main frame member, this flange and the web 22 being cut away as shown in Fig. 2. The slide is fed by a hand lever 50 clamped on a spindle 51 that also has an arm that operates the stem of a normally spring-closed air valve 64 to open the valve at the end of the return stroke of the slide admitting air at 62 to eject the blank that is conducted by a curved guide 70 to a receptacle 71, and at 73 to blow away the cuttings. The blank, inserted by hand, is clamped by a blade 11 that enters the slot in the head and is carried by levers 56 straddling the slide 5 and pivoted to it at 58. A cross-pin 59 on the levers is connected to tension springs 60 anchored to the web 22 at 61. As the slide 5 returns, the pin 59 contacts the edge 23 at the cut-away part of the web and lifts the blade clear of the slot prior to ejection. On the forward stroke, the pin 59 remains in contact with the edge 23 until the blade seats in the slot in the blank after which the pin leaves the edge stretching the springs and increasing the clamping pressure. The drill is driven from an electric motor 41 through belts 38, 32 and a countershaft 34. The spindle housing 28 is carried on a part of the top flange 19 and this flange may be stiffened by struts 49 beneath both the drill and the work-slide. Lubricant is supplied to the drill from a container 42 by a drip pipe 44 and is collected by a tray 48 supported by a spacer 47 from a base-plate 45 with angle-iron feet 46.

Title: Improvements relating to the extraction of oils or fats from oleaginous vegetable matter
IPC: C11B1/10
Filed: 1922-05-08
Abstract: 179,931. Cellulose et Papiers, Soc. de Recherches et d'Applications. May 12, 1921, [Convention date]. Fats and fatty oils, extracting by solvents. Oils and fats are extracted from oleaginous vegetable matter, by wetting it, with or without previous preparation such as grinding, with a quantity of solvent less than one half of that usually employed, and then extracting the solvent and oil together under low pressure, say 1-10 kilograms per square centimetre. The temperature of operation is kept below that of volatilization of the solvent, e.g. 30-70‹ C. In one form of apparatus, Fig. 1, a vessel 1 provided with a plunger 2 is used. The solvent is introduced by an inlet 4, and the oil and solvent run off through an outlet 6. The residual cake 5 may be heated to drive the solvent off through a pipe 7. Another form of apparatus, Fig. 2, consists of a rotary extractor 8, provided with an oppositely-rotating agitator, and enclosed in a chamber 9 having an inlet 10 and an outlet 11. After treating with solvent for say 10-20 minutes, the vegetable matter is subjected to rotation at a speed corresponding with the low pressure desired. In examples, palm nut cake containing 45 per cent of oil is treated with 10 per cent of kerosene or petrol, and a pressure of 10 kq. per sq. cm. is applied for 20 minutes at 75‹ C.. Similarly crushed ground-nuts containing 49 per cent of oil are wetted with 20 per cent of alcohol, and a pressure of 10 kg. per sq. cm. is applied for 15 minutes at 50‹ C.

IPC: F02M17/36
Filed: 1926-05-21
Abstract: 252,389. Jensen, L. May 22, 1925, [Convention date]. Spray carburettors.-Rich mixture is supplied to the mixing-chamber 4 by an inclined passage 12 formed in a plug 5 cut away at the sides to form air passages, the plug being surrounded by a manually-rotatable valve 6 provided with ports 6<1> and controlling the admission of air from the inlet 3, and the outlet of mixture to the chamber 4. Fuel flows through orifices 11 in the bottom of the plug 5 to the interior of a tube 13 held in position by a cap 15 and provided with a calibrated orifice at each end; fuel and air enter respectively through these orifices, the rich mixture passing through the annular space 14 to the passage 12. The orifices in the tube 13 are of different sizes, and by removing the cap 15 the tube may be inverted, or replaced by another with different sized orifices, to vary the fuel supply according to atmospheric conditions. The valve 6 also controls the admission of air through a port 7, the inlet to which is controlled by a slide 8, this air being cut off when the valve is fully open. An orifice 6<11> for slow-running is provided in the valve, and also an annular groove 6A opening into the bottom of the ports 6<1>, air passing through the groove at high suctions. The fuel level in the float chamber 20 is controlled by a cup 24 provided with a valve 25, the fuel flowing over the rim 24<1> of the cup until it is sufficiently weighted to close the valve. For starting, the cup 24 may be lifted by a rod 26.
