Title: An improved fuel economy device for use on internal combustion engines
IPC: F02D9/00
Filed: 1949-12-05
Abstract: 688,474. Auxiliary fuel charges. HILL, J. A. Dec. 5, 1950 [Dec. 5, 1949], No. 31134/49. Class 7 (ii). In an improved fuel economy means for internal-combustion engines in which a connection 22, Fig. 1, is made between the crankcase and the engine intake manifold, a venturi 11, Fig. 2, is provided between the engine and carburetter, not shown, and the connection 22 is made substantially at the venturi throat. The apparatus comprises a body 1, Fig. 1, that is shaped to be inserted between the flanges of the intake manifold and the carburetter and which has a bore 1a of the same diameter as that of the manifold; the bore 1a communicates with an inlet passage 4 through a valve chamber 3 and a passage 2, which inlet passage is joined by the copper or plastic pipe 22 to the oil filler cap or some other part of the crankcase. Within the bore 1a is inserted the venturi 11, Fig. 2, which has a groove 11a in its outer surface that communicates through a number of radial inwardly-tapering bores 11b, Fig. 1, with the interior of the venturi and hence the intake manifold. In the chamber 3 is a rotary valve 6 on a spindle 5, the upper part of which latter is provided with a vane 8, Fig. 2, located within the venturi, and the lower part with a counterweight 10. When the engine is first started mixture only from the carburetter passes to the engine through an opening 8b in the vane 8 and as the engine gains speed the suction increases and' moves the vane 8 thereby opening valve 6 to permit fuel-laden air from the crankcase to pass up passage 2 into groove 11a and thence by bores 11b into the inlet manifold. The heat of the, crankcase, air promotes vaporization of the normal air-fuel mixture, and the oil particles in the air improves cylinder lubrication. In a modification, the vane has an outer inclined portion to prevent fluttering. In a further modification the valve is controlled conjointly with the throttle and the vane is dispensed with.

Title: Improvements in or relating to circuits for providing a signal indicating the presence or the absence of clock pulses
IPC: G06F1/04
Filed: 1962-08-14
Abstract: 939,308. Voltage detecting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 14, 1962 [Aug. 17, 1961], No. 31165/62. Class 37. [Also in Group XL (e)] A circuit for detecting the presence or absence of needle-like clock pulses comprises a bi-stable circuit FF1, the 1 input of which is fed with the monitored clock pulses, the 0 input being fed from the output of a pulse generator delivering needle-like pulses of a lower frequency and the output of the bi-stable circuit controls a gate P also fed with the lower frequency pulses, the operating delay of gate-P being greater than the duration of each lower frequency pulse. As shown, a generator X delivers square wave clock signals in phase opposition via gates Q1, Q2 to terminals 7, 8. The square waves are differentiated at 1, 2 and the resulting positive needle-like pulses from each phase are passed via diodes 4, 5 to the transistorized Eccles-Jordan bi-stable circuit FF1. A square wave from a second clock generator Y is differentiated at 3 and the positive needle-like pulses therefrom fed to the 0 input of FF1 so that the circuit is set to its 1 state by each positive pulse from X and reset by each positive pulse from Y. The operating delay of FF1 and the gate P is such that, under normal circumstances, needle-like pulses from diode 6 do not have time to pass gate P. In the event of failure of generator X, circuit FF1 will remain in its 0 state hence the next pulse through diode 6 will set the bi-stable circuit FF2 to its 0 state, closing gates Q1, Q2 and opening gates R1, R2, thereby connecting the output terminals 7, 8 to the auxiliary clock generator Y. Bi-stable circuit FF2 is reset manually by switch S2. Operation of the circuit may be checked by opening switch S1. Fig. 1 (not shown) relates to an alarm circuit in which gates Q1, Q2, R1, R2 are omitted and clock generator Y is replaced by a pulse generator having a frequency two-thirds that of the monitored clock generator.

Title: Automatic change speed gear mechanism
Filed: 1932-11-07
Abstract: 393,851. Change-speed gearing. VETTER, J. M., 345, Newtonstraat, The Hague. Nov. 7, 1932, No. 31325. [Class 80 (ii).] Change-speed gearing for vehicles is operated automatically by a fan upon or geared to the driven shaft which actuates a pneumatic switch which distributes current selectively to the valves of engine-suction servomotors, one for each speed. The fan 34, Fig. 7, on a shaft 2 geared to the driven shaft 59, Fig. 2, sucks air in through a sieve 36 and sends it by a pipe 37 past a relief valve 45, Fig. 3, which is connected to the accelerator to steady the pneumatic distributor, and into a coil expansible tube 39 of the distributor 38. The tube 39 is connected at 42a to a switch arm 42 which moves over contacts a .. d corre. sponding to 1st, 2nd, 3rd, and 4th speeds. A selective switch box 46, Fig. 5, secured to the dash-board has contacts N, A for neutral and for automatic action, and others R, 1 .. 4 for reverse and for the four forward speeds, which can thus be operated manually. Current from a battery &c. passes through the switch box 46, then through the distributor 38 to a pair of control coils 22, Fig. 1, of a servomotor which pulls a control rod 17 corresponding to the speed selected. There is a servomotor, a rod 17, and a pivoted lever 14 for each of the five clutches 3 shown in Fig. 2. These are plate clutches which overlap in action and the gearing shown has a driving- shaft I, a countershaft 2, and a driven shaft 59. The tooth reaction of helical gears 1b, 1c, 1d for first, second, and third speeds tends to keep the plate clutch engaged. Ihe last clutch 3 on the right is for direct drive. Each rod 17 is pulled to effect a speed by two pistons 18, Fig. 1, which come into action in succession to cushion the start of the stroke. Valve doors 29 on these pistons by gradually covering suction ports 27 cushion the end of the stroke. The engine suction is applied at 26 and the coils 22 act by lifting two leather-covered valves 23 admitting suction under two pistons 21 on valve stems 24 which are thus sucked downwards against springs 25. Piston valves 19 on the stems 24 close two air inlets 28, one to each cylinder 72, and then other valves 20, one after the other, open the outlets 27 to the main suction ports 26. The gear clutch corresponding is now in and remains so until the fan 34 causes the distributor arm 42 to move to another contact whereupon the rod 17 previously in use is returned to the right by a spring 30, Fig. 1, and another motor acts. The electric current passes from the coils 22 of the motor in action from a trailing connection 71 through a lamp and back to the battery, and the lamps are of different colours to indicate which speed is in operation at the time. An engine clutch is used with this transmission.

Title: Improvements in or relating to wood preserving agents
IPC: B27K3/32
Filed: 1954-11-01
Abstract: 796,871. Preserving wood. ALLGEMEINE HOLZIMPRAGNIERUNG DR. WOLMAN GES. Nov. 1, 1954 [Nov. 6, 1953; Oct. 11, 1954], No. 31535/54. Drawings to Specification. Class 140. A wood preserving composition comprises 2 gram atoms of hexavalent chromium in the form of alkali metal salts of chromic acid or of dichromic acid or in the form of chromic acid, 6 m mols. of alkali metal fluoride and/or n mols. of alkali metal arsenate, wherein m+n=2 and from 0.2 to 1.2 times the quantity of hydrogen equivalents in the form of acids-other than arsenic acid-as are required by theory to neutralize the alkali liberated from said compositions during the reduction of the hexavalent chromium by substances present in the wood. Chemical equations are given with the aid of which the quantity of hydrogen equivalents, in the form of acids, required by theory may be calculated. The alkali metal ions may be sodium or potassium or mixtures thereof which may also contain the ammonium ion. As acids there may be used sulphuric acid, mixtures of ammonium sulphate and sulphuric acid, alkali metal bifluorides, alkali metal bisulphates, potassium pyrosulphate or ammonium bifluoride. The salt mixtures of the invention may also contain dinitrophenols or dinitrocresols. The reactions, which take place, in practice, by the action of reducing agents, in the wood itself, lead to the fixation of fluorine as chromium cryolite and of arsenic as chromic arsenate. Besides inorganic acids and substances yielding inorganic acids by hydrolysis or otherwise, organic acids may also be used if they are not too rapidly oxidized by bichromates or chromates. In an example, small cubes of pine sap wood are dried and then vacuum impregnated with solutions containing disodium hydrogen arsenate, sodium bichromate and different amounts of sulphuric acid.
