Title: Improvements in or relating to the operation of compression ignition engines
Inventor: MONNOT GEORGES
IPC: F02B7/02
Filed: 1958-05-14
Abstract: 878,278. Direct-injection four-stroke engines. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. May 14, 1958 [May 15, 1957; Nov. 18, 1957], No. 15566/58. Drawings to Specification. Classes 7(2) and 7(3). In a compression-ignition engine two successive feeds of the same fuel are made to each cylinder for each cycle, the first feed being injected from 340 to 382 degrees of crank-shaft rotation before the firing T.D.C. to form a combustible mixture too weak to ignite before the second feed is effected and constituting up to about 50% of the total fuel supply. The second feed is injected from 320 to 360 degrees of crank-shaft rotation after the first, preferably as the first is about to ignite. The inlet air valve opens at 12 degrees before T.D.C. and closes at 36 degrees after B.D.C. and the exhaust valve opens at 36 degrees before B.D.C. and closes at 12 degrees after B.D.C. The first feed mixes with residual gases of the exhaust stage of the preceding cycle and reacts therewith until their temperature is lowered by the inlet air, the resulting partially oxidized mixture being presumed to cause even burning of the second feed. Quantitative results and pressure-time graphs of tests with a twocylinder in-line engine are given, the engine charge, speed and fuel type (petrol, gas-oil, paraffin) and the injection timing and amounts being varied. There may be two-injection pumps rotating at half crank-shaft speed, one for each feed, and each having as many cylinders as the engine, a cylinder from each pump feeding in parallel the injecter of a corresponding engine cylinder. Alternatively there may be one pump having twice as many cylinders as the engine; or having as many cylinders as the engine and operated by a double-lobe cam which may be unsymmetrical; or a pump operated at crankshaft speed may be used.

Title: Electric selecting systems
IPC: H04Q3/00
Filed: 1942-11-06
Abstract: 555,721. Electric selective signalling. STANDARD TELEPHONES & CABLES, Ltd. Nov. 6, 1942, Nos. 15703, 15704 and 15705. Convention dates, Nov. 21, 1941, Nov. 21, 1941 and Nov. 26, 1941. [Class 40 (i)] [Also in Group XXXIX] In a system in which one of a number of circuits is selected by the discharge of an argon &c. tube associated individually with it, an auxiliary electrode of each of the tubes is connected to a common resistance so that the discharge across the auxiliary gap in one tube produces a voltage drop which prevents the discharge of the others. The invention is described with reference to arrangements for preventing interference between simultaneous calls in a telephone system, (see Group XXXIX), Figs. 1 to 7 (not shown). In another arrangement for selecting one of a number of relays in accordance with the frequency of a received current, the signal voltages developed across the inductances 834, 836, 838 of tuned circuits are applied to the starting electrodes 827 ... 829 and ionization occurs between these electrodes and the cathodes in the tube corresponding to the received frequency and also in adjacent tubes. In the tube corresponding to the received frequency, however, the discharge transfers to the screen grid before it can do so in the others, and the resulting screen current produces voltages in the common resistances 821, 826, to prevent the spread of ionization in the other tubes.

Abstract: 184,927. Bruhn, F. W. G. June 11, 1921. Disc recording-apparatus.-In an instrument for recording upon a clock-driven disc the revoit.- tions made or distance traversed the moving or stationary condition of the machine or vehicle is separately recorded upon the disc by means of a vibration-responsive element. Provision is made for varying the rate of drive for the recorddisc and for recording the times, during whicn the rates are respectively operative. The recorddisc placed upon a fixed central plate 54 provided with retaining lips 55, is rotated by a pinion 68 driven from the clockwork 51 and bearing upon the rear face of the disc. By sliding a fingerpiece 73 connected to a clutch arm 72, the pinion can be shifted along its axis so as to gear with either of the crown-wheels 66, 67 and thus rotate the record-disc at one of two different speeds to receive either a 12-hour or a 24-hour record. The disc is maintained in driving contact with the pinion by means of a two-grooved bobbin 82<1> carried bv a spring-controlled pivoted arm 80, and is incidentally marked by the pinion along the inner or outer margin of the annulus 79. The distance and motion-recording punches 11, 13 operate along the edge of the curved abutment 16, normally held against the disc but displaced for accessibility thereto when the cover is removed. The drive from the vehicle wheel intermittently rotates, through an eccentric forked lever 22 and pawl 27 an interchangeable ratchet wheel 9 mounted on a shaft 30 and geared through a worm 32 with the odometer 19. The perforator 11 is carried by one arm of a bellcrank lever 40 caused to rock by a cam 37 fixed on the live spindle of the odometer and is inter mittently struck to perforate the record-disc by means of a hammer 42 operated from a ratchetcam 33 on the shaft 30.

Abstract: 593,215. Wave-guides. BRITISH THOMSON-HOUSTON CO.; Ltd., BROWN, L. W., and TAYLOR, H. B. June 25, 1945, No. 16151. [Class 40 (v)] In apparatus for measuring standing wave patterns in a wave-guide by means of a probe extending through a. slot into the guide, the guide is designed so as to ensure that the extension of the probe into the guide remains constant as the probe is traversed along the guide. In Fig. 2, a probe 4, connected to a detector in a housing 6, is mounted on a carriage 5 adapted for moving along a guide 1. The guide comprises a channel member 1 and a cover member 2 having an accurately finished undersurface which extends beyond the sides of the guide to provide a runway for steel balls 8 positioned between member 2 and accurately finished surfaces on overhanging extensions 7 of the carriage 5. Spring-urged balls or wheels 9 urge the carriage upwards against the balls 8, while lateral stability is ensured by a ball 10 and a spring-urged ball 11. In the embodiment shown in Fig. 4, the carriage 5 has an accurately finished undersurface of cylindrical or prismatic form which rides on balls 13 which have been accurately positioned relative to the accurately finished undersurface of cover member 12. The carriage is steadied by the interaction of a leaf spring 15 on one side of the carriage, and an adjustable spring-pressed ball 16 on an overhanging extension on the other side of the carriage. The guide may be of circular crosssection (Fig. 5, not shown).

The compounds of the invention may be used to separate sterols and chromanols from animal or vegetable fats and oils by formation of the complex in the presence of an anhydrous solvent, separating the complex by fractional crystallization, and decomposing the complex by addition of water.  Fractional crystallization may be employed to separate chromanols from sterols or from other chromanols, or to resolve chromanols into their optical isomers.  The compounds of the invention have antioxidant properties, e.g. for fats and oils; the piperazine complexes of a , b - and g -tocopherol have Vitamin E activity, and the complexes with sterols and 6-chromanols have anthelmintic activity.
