Title: Improvements in the manufacture and production of artificial masses, lacquers and solutions containing both cellulose esters and rubber
IPC: C08L1/10
Filed: 1928-08-27
Abstract: 321,258. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 27, 1928. Adhesives.-Solutions of low viscosity suitable for use as adhesives and containing both cellulose esters and rubber are obtained by the use of esters of unsaturated aliphatic carboxylic acids. including the aromatic substitution products of the said acids. Suitable esters include volatile esters of acrylic and crotonic acids, especially a crotonic ethyl ester, and esters with an alipbatic alcohol of the acrylic acid series containing from 3-6 carbon atoms. Any tendency to form polymerization products is avoided by carrying out the process without heating and avoiding the influence of daylight. High boiling esters of the acrylic acid series may be used as softeners, or other softeners, and also drying oils, solvents, dyestuff and fillers may be added. Solutions in high boiling solvents or plastic masses are prepared by the use of esters of high molecular homologues of acrylic acid e.g. methyl oleate ethyl, propyl and butyl cinnamates : the cellulose esters and rubber being dissolved in the solvent, if desired at an elevated temperature in a kneading machine. In the case of nitrocellulose rubber solutions, solutions of nitrocellulose, in a low-boiling solvent e.g. acetone, ethyl acetate &c. may be mixed with solutions of rubber in methyl oleate &c. For the preparation of acetyl-cellulose-rubber solutions, the solutions are preferably prepared separately, with the simultaneous use of the usual solvents for acetylcellulose to effect solution and then mixed. The known solvents and diluents for the preparation of nitrocellulose and acetylcellulose solutions may be employed, together with softening agents e.g. alkyl or aryl phosphates, camphor or camphor substitutes, phthalic acid esters or castor oil, colouring materials, resins or fillers. Examples with proportions are given.

Title: Air-fuel ratio control system for internal-combustion engines with controlled ignition
IPC: F02M7/10
Filed: 1975-06-11
Abstract: 1509577 Fuel control systems CONSIGLIO NAZIONALE DELLE RICERCHE 11 June 1975 [24 June 1974] 24973/75 Heading F1H A fuel control system for an I.C. engine comprises a main pump 12 and a fluidic control device 29 receiving fuel supplied via three lines, directly via a main or power line 41; adjustably via a line 40; and by way of a diaphragm valve 10 via a line 39, lines 39 and 40 constituting control inputs. Valve 10 which may be adjusted during engine operations, responds to the pressure upstream and downstream of throttle valve 6 located in an inlet 1 having coaxial Venturi 7, 8. The fuel leaves device 29 via two outlets, a line 30 leading to a recycle reservoir 14, and a line 32 communicating with the inner Venturi 8 via a spray nozzle 3 and with an inlet downstream of the throttle valve via a slow running control valve 5. Electrical valves 27, 28 controlled by a pressure switch 25 shut off the fuel-flow when the pressure within the intake manifold 9 falls below a predetermined minimum value such as occurs on engine overrun. Adjustment in line 40 may be effected by a valve 11. Valve 10 includes a spring loaded diaphragm 35 adjustable by a screw B7 and connected to a needle valve 38 governing the fuel-flow through line 39, a pressure limiting device 44 maintaining constant the fuel pressure downstream of the pump 12 which is electrically driven. An electrical fuel injector 19 controlled by a pressure switch 58 provides extra fuel for high load conditions, the switch being governed by a pneumatic cylinder 23. A closed or partially open throttle valve causes the inlet pressure downstream thereof to become subatmospheric; air entering cylinder 23 via check valve 21 therefore causes retraction of a piston 24 against the compression in a spring 22. When the throttle valve opens under heavy load conditions such as acceleration, the inlet pressure rises and piston 24 returns, the indrawn air closing switch 58 which activates the injector 19. The opening time of the injector may be varied by an outlet valve 61. In another embodiment, Fig. 2 (not shown), cylinder 23 is connected directly to chamber 47 of valve 10 to provide pressurized air to the chamber to open the needle valve for providing extra fuel during high load conditions. In a third embodiment, Fig. 3 (not shown), the electrical pump 12 is replaced by a volumetric pump driven in time with the engine, the limiting device 44 being omitted. In a fourth embodiment, Fig. 4 (not shown), valve 11 is omitted and line 40 is connected upstream of pump 12, the fuel through the line being delivered via a volumetric engine driven pump. Fig. 5 shows a fifth embodiment in which the fuel to valve 10 is delivered by a volumetric pump 50b driven in time with the engine.

Abstract: 888,130. Change-speed gear; clutches. FORD MOTOR CO. Ltd. July 18, 1960 [July 17, 1959], No. 24980/60. Class 80 (2). [Also in Group XXXI] In a variable-speed transmission of the type comprising a number of planetary gear units arranged in series and in which the gear ratios are established by the operation of brakes and multi-disc clutches, provision is made for lubricating any clutch in which relative rotation of the two sets of discs may occur during operation. General arrangement.-The transmission shown is for a tractor drive giving ten forward and two reverse gear ratios, and is also arranged to enable a power take-off shaft 22 to be connected to the input shaft 10 or output shaft 12. The main transmission comprises four planetary gear units 14, 16, 18, 20, three band-brakes 86, 106, 136 and three fluid-pressure-operated clutches 96, 126, 146. Gear units 16, 18 are effective to provide five forward and one reverse gear ratios, while unit 14 provides an overdrive which may be combined with each of the ratios obtainable with units 16, 18, and unit 20 is a are actuated by a cam 190 on the gear 156 to reduction gear for all the ratios provided by units 14, 16, 18. A " park " condition, with input shaft 10 rotating, may be obtained by engaging the second and third brakes 106, 136. A pump 48 driven by input shaft 10 furnishes pressure liquid for operating the control system and for lubrication. Clutch lubrication.-In first gear with the third brake 136 and third clutch 146 engaged, and in third gear when the first brake 86 is also engaged, relative rotation of the discs of the second clutch 126 occurs and to reduce friction under such conditions the clutch is lubricated by liquid from pump 48 which passes along an axial bore in the main shaft 10 and through a radial passage 242 to the clutch drum 240, from which it escapes between the discs through axial slots 270, Fig. 3. Power take-off.-Input shaft 10 may be connected to take-off shaft 22 by drive pinions 62, 64 meshing with a compound pinion 184, 186, selection of the appropriate drive-pinion being effected by an axially-movable toothed clutch 60, and the drive being established by the engagement of a fluid-pressure-operated disc clutch 26 housed within compound pinion member 182. Bevel gearing 190, 202 is arranged between member 182 and shaft 22 and this may be used to drive one or more auxiliary transverse shafts. Output shaft 12 is connected to shaft 22 by pinions 172, 174, the latter of which is normally free on shaft 22, but may be coupled therewith by an axially-movable toothed clutch 226.
