Title: Electronic mixture-proportioning systems
IPC: F02D43/00
Filed: 1971-04-19
Abstract: 1337448 Electronic fuel metering systems ROBERT BOSCH GmbH 19 April 1971 [26 March 1970 5 Feb 1971] 25333/71 Heading G1N In an electronically controlled I. C. engine fuel system, a function generator is arranged to control the metering of fuel in dependence upon engine operating parameters so that predetermined values of excess-air coefficient #, (i.e. a measure of the fuel/air ratio), are achieved. The system can then be arranged so that below a certain speed a weak mixture is provided to produce minimum exhaust of unburnt gases and above this speed a rich mixture is provided for optional engine performance. As shown in Fig. 3, a function generator 19 controls the metering of fuel in dependence upon signals from an accelerator angle sensor 14 e.g. a potentiometer, a rate of air-flow sensor 15, 16 or 15a, 16a and a speed sensor 18, e.g. a multi-vibrator. Sensor 15, 16 is a heated temperature responsive resistor mounted in a bridge circuit, Fig. 3a (not shown), and sensor 15a, 16a is an aperture plate connected to the wiper of a potentiometer, Fig. 3b (not shown).  To further reduce the amount of unburnt gases being exhausted, the position of the air throttle may be additionally controlled, Figs. 4 - 4c (not shown), the ignition timing and spark duration may be additionally controlled, Figs. 5- 9 (not shown), and the injection timing (if the system is an injection system), and the recirculation of the unburnt gases may be additionally controlled, Fig. 10 (not shown). Other engine parameters which may be utilized in the control are air temperature and pressure, water temperature, and amount of unburnt gases.

Title: Process for refining molten metal
IPC: C21C7/072
Filed: 1977-06-17
Abstract: The refining gas, for example nitrogen, is injected into the molten metal by means of an injection device comprising a rotor (1) with fins (2), driven by a vertical shaft (3) surrounded by a stationary sleeve (4). The gas is introduced through an annular passage arranged between the shaft and the sleeve and comes out by virtue of a clearance provided between the rotor and a grooved stator (11). In the molten metal, the rotor creates currents which make the bubbles of refining gas travel outwards and downwards, and this improves the gas-metal content. Since the gas is preheated in the sleeve (4), the bubbles do not expand within the metal and remain small. <IMAGE>

Title: Improvements in or relating to a process of making synthetic resins and the productsresulting therefrom
IPC: C08G8/28
Filed: 1950-10-19
Abstract: A synthetic resin is made by etherifying at least one phenolic hydroxyl group of a natural catechol tanning agent with mono-chloro or -bromo-acetic or propionic acid, by reaction in an alkaline medium with not more than 2 mols. of the acid per mol of the tanning agent, condensing the product thus formed with formaldehyde, and thereafter etherifying at least one of the remaining phenolic hydroxyl groups by reaction with an aralkyl halide in an alkaline aqueous medium.  The natural tanning agents specified are quebracho extract, wattle, cutch and mangrove. Benzyl chloride is the preferred aralkyl chloride.  In the example monochloracetic acid is added to a cooled mixture of quebracho extract and aqueous caustic soda followed by heating of the mix to 90-95 DEG C. for 1/2 hour.  To this solution, after cooling, is added further caustic soda and aqueous formaldehyde, the mixture being heated, but cooled again for the addition of benzyl chloride and thereafter heated.  A solution of caustic soda and sodium hydrosulphite is added to the mixture and the whole mass, while still hot, is poured into trays and solidified.  The free resin may be obtained by acidification with, e.g. hydrochloric or sulphuric acid. The resins, which are soluble in alkalis and solvents such as benzene, toluene, methanol, ethanol and propanol, may be used for making compositions for coating, e.g. leather, cloth and paper, as disclosed in Specification 703,409. Specification 703,407 also is referred to.

Title: Process for obtaining metals containing a regulatable quantity of hydrogen
IPC: B01J37/34
Filed: 1962-07-03
Abstract: Raney and similar metals in powder, or shaped forms containing absorbed hydrogen are freed from it wholly or partly, by treating in an electrolytic cell, where it is immersed in the electrolyte but not in contact with the electrodes.  The proportion of the current passing through the metal to remove the hydrogen depends on the shape and metal of the body, and is measured by the ratio of volume of cathode gas evolved to the amount of desorbed gas. This is determined in a preliminary test.  The treated body is no longer pyrophoric, and may be re-charged with hydrogen electrolytically.  Suitable electrolytes are sodium carbonate or caustic soda, and examples are given of treating Raney cobalt and nickel; immersed in alkali solution at the bottom of a U-tube, platinum electrodes being inserted at the top of each limb.  The treatment was effected at 0.2 amps. for 30-300 minutes.

Abstract: 1434918 Non-metallic springs METZELER Ltd 2 May 1973 [5 June 1972] 26180/72 Heading F2S A resilient mounting, e.g. for an I.C. engine, has two metal members 11A, 12A bonded to an intermediate elastomeric member 13A, the first, 11A, being partly embedded in the member 13A and the second having at least one side wall 14A or 16A extending along a side of the member 13A, there being a space 18A in the elastomer extending from an exposed portion 19A of the elastomeric member 13A between the member 11A and the side wall 14A or 16A. The space 18A closes at at least one side of the mounting, when there is sufficient relative displacement of the metal members 11A, 12A, so that resistance of the mounting to the displacement increases. A surface of the elastomer in the space 18A has at least one convex surface 21A to make the mounting progressively stiffer to displacement. Grooves 23A in the surface 21A close off progressively with the displacement to modify the stiffening. The mounting shown is used as a front mounting for an engine. A wall 15A of member 12A is uppermost and horizontal. The first (cast or pressed) member 11A has a rib 26 and the second member 12A has studs 25A, for securement of the mounting. In other embodiments, the second member (12) has three or four sides and each member has at least one stud. These may be aligned only by static load. An embodiment, Fig. 6, with a four-sided second member (12F) is intended primarily for compression of the elastomer, in use, by displacement of the first member (11F) towards a back wall of the second (12F). The mounting is made using a two-part vulcanizing mould with at least one insert for forming the space 18. The elastomer is vulcanized in situ in the second member 12 and the first member 11 embedded.
