Title: Method of and means for producing fuel in internal combustion engines
IPC: F02M31/08
Filed: 1949-04-28
Abstract: 681,811. Vaporizers. WILLIAMS, K. April 28. 1949 [May 17, 1948], No. 11365/49. Class (iii). In a method of producing fuel for an internalcombustion engine having a carburetter 10 and a heat-exchanger 3 comprising admixing water in a firely divided state, with the working substance to be induced in the engine between the carburetter and heat-exchanger and raising the temperature of the water and working substances gradually over a range from the existing atmospheric tempeature to approximately 170‹ to 180‹ F. whereby the water in the mixture is vaporised at tempeatures below its boiling point, at least part of the heat required for the vaporization of the water is supplied by the latent heat of condensation of water vapour in the exhaust gases; the water may be introduced in sufficient quantity to substantially saturate the mixture at the upper limit of temperature. The fuel-air mixture from the carburetter 10 has water added to it from another carburetter 7 and an atomizing jet 5, the water being cut off at starting until normal operating temperature is reached. The air-fuel-water mixture tnen traverses a reverse flow heat-exchanger 3 before entering the inlet manifold 19. The heat exchanger 3 which comprises a number of curved, fine-bore tubes 14 is connected to the exhaust, and the condensate either escapes with exhaust gases or is passed from a water trap in the exhaust outlet 17 to an economizer, not shown. The engine water jacket and radiator may be materially reduced in size or dispensed with. In a modification the water is atomized and injected directly into the fuel-air mixture in the heat-exchanger by a nozzle supplied from an engine driven pump whilst in compression-ignition engines, air only is passed over the water atomizing means. The heat-exchanger, cylinders, cylinder heads and inlet and exhaust manifolds are lagged. The Provisional Specification describes also a heat exchanger with one through conduit instead of a number of fine-bore tubes; the exhaust pipe passes through the conduit, and the spaces between and within the conduit and pipe are filled with such material as copper wool. The condensate from the exhaust may be removed to the container from which the water nozzles are fed.

Abstract: 557,251. Hoppers. AVERY, Ltd., W. & T., and PARKER, A. H. Aug. 15, 1942, No. 11448. [Class 78 (i)] [Also in Group XVIII] In an automatic weighing machine wherein shortage of material within the supply hopper causes movement of a hinged flap a therein to arrest the operation of the machine, the hinged flap is indirectly connected (as by a bar d and lever e) to a rod g having a lateral extension g<SP>1</SP> located beneath the usual toggle linkage h of the feed gate c. With sufficient material in the supply hopper, the lateral extension g<SP>1</SP> breaks the toggle joint and permits the feed gate to open in the normal operation of the machine. If a shortage of material occurs, the flap a rocks, and lowers the lateral extension g<SP>1</SP> thus allowing the toggle linkage to straighten and prevent the feed gate from opening, thereby arresting further operation until an adequate supply is provided. Specifications 16286/12 and 119,264, [both in Class 143], are referred to.

Apparatus for cutting thin hard material comprises multiple blades 123 separated by spacers 124 extending substantially over the whole length and width of the blades and clamped therewith in backing plates 42 carried by a blade support frame 31 which is reciprocated along slideways 23, 24 on a main support frame 14, and a workpiece feed mechanism 81 mounted on a bracket 71. The workpiece may be a thin wafer of semi-conductor material having a plurality of microminiature electronic circuits which is to be cut into a plurality of small dice of, for example, 0À030 x 0À030 inch, each bearing a complete circuit, the wafer being 0À010 inch thick. Support-structure 14 is mounted on three pads 16 on a support 12 having three feet 17. A blade-supporting frame 31 is connected by a quick-release device 61 to a plate 56 having a slot 57 engaged by an eccentrically driven pin 55 whereby the frame is reciprocated along the slideways. One end of the backing plates 42 is located by pins 131 on the frame, and the other end of the frames has means for aligning the blades with the movement of the frame. The edges of the blades may be ground so as to be in a common plane, and when worn may be adjusted by shims. The bracket 71 is secured to the support structure 14 by bolts 77 and has a nylon bearing 91 slidably supporting a cylindrical plunger 94 of the feed mechanism which is prevented from rotation by rollers 104 engaging a bar 101 fixed to an upper flange 95 supporting a workpiece supporting plate 96. The plunger is urged upwardly by weights 115 on a lever 110, which is pivotally mounted on the support 12 and is formed with a yoke having rollers 117 engaging the flange 95 and can be lowered by movement of a pivoted lever 192 engaging a roller 191 on the plunger. The plate 96 supports a series of vacuum assemblies 141 for holding the workpieces, each assembly being disposed between a pair of supports 151 having clamp member 153. To locate and orientate the workpieces, a thin transparent flat member (161, Fig. 7) is mounted on the supports and the blades are reciprocated over the member in the presence of abrasive to scribe reference lines thereon. The member is then replaced by two short blocks (162, Fig. 8) and reference lines are scribed thereon by the blades. The workpieces are then bonded to circular workpiece supports (175) and held by a light vacuum on the assemblies (141), and the thin transparent member (162), with spacing blocks (163) secured thereto, is inverted end for end and aligned, by means of a viewing device and the reference lines with the short blocks (162). The workpiece is then accurately positioned beneath the reference lines and held in position by a high vacuum. The procedure is repeated for each assembly and the transparent member removed so that the blades can be reciprocated to cut the workpiece. The procedure is then repeated with the workpiece displaced through a right-angle to produce the dice.

Abstract: 1302595 Washing textiles RIMAR SpA 11 March 1970 [26 March 1969] 11671/70 Heading D1L Textile fabrics are washed with a solvent (which may be an organic solvent, water or detergent solution) in an apparatus comprising a perforated chamber or basket 1 which is swingable about an axis Z and through which the fabric 19 passes in folded form, this chamber being within a stationary tank 12 containing the solvent 2. The chamber 1 is, as shown, of semicircular shape the passage being broader at the outlet end B for the fabric than at the inlet end A. Blades 17 are arranged protruding from the perforated sides 15 and 16 of the chamber, alternately on one side and the other similar blades 4 being arranged on the surfaces 13 and 14 of the stationary tank 12 interleaving with those on the chamber 1, such that when the chamber is swung back and forth by means of bar 18 and crank 5 and 5', alternate pressure increases and decreases on either side of the chamber where the blades approach one another or move apart cause a pumping action of the solvent across the chamber through the perforations. The increasing width of the chamber from A to B also causes the fabric to move through the chamber from A to B as the chamber swings. The solvent 2 is circulated by pumps 28 and 29, these drawing solvent from the tank and passing it to sprays 30 and 34, to the latter spray via a distillator (not shown). The fabric is drawn off via hollow rolls 22 and 23 both of which are subject to a suction draught of air, this drying the fabric.

Abstract: 1430499 Retractor reel SIGMATEX AG 15 March 1974 [16 March 1973 1 Oct 1973] 11688/74 Heading A3V A reel locatable by a pawl 74 engageable with ratchet 32 includes a flywheel 42 rotatable on the reel shaft and a locking member couplable between the shaft and flywheel so that on relative rotation there between at a predetermined acceleration of shaft, locking of the pawl is initiated. The reel is mounted on a shaft 22 having an enlarged end 34 which entrains the flywheel 42 by means of a peg 46 and coil, spring 50 housed in a slot 38. A locking dog 54 is lodged in mutually opposite recesses 40, 52 in the end 34 and flywheel. An annular actuator 56 having an internal ratchet 60 surrounds the end -34 and is urged against a stop by a spring 66. When the belt is un-reeled rapidly, relative rotation between the end 34 and flywheel 40 forces the dog radially outwards to entrain the ratchet 60. Rotation of the actuator takes arm 64 anti-clockwise so that it strikes pawl 74, forcing it into the path of the teeth of a ratchet 32 fixed to the reel shaft. The reel is thereby arrested. In a modification the dog and coil spring are replaced by a leaf spring (110 Fig. 7 not shown) flexed to project beyond the flywheel periphery on relative rotation of the flywheel and shaft to initiate locking. The reel will also lock if pendulum 86 is displaced thereby raising lever 96 against the pawl.
