Title: Apparatus for determining the distribution of anti-knock constituents in a fuel among the cylinders of an internal combustion engine
IPC: F02B47/00
Filed: 1945-07-25
Abstract: <PICT:0598084/III/1> An apparatus for determining the distribution of anti-knock constituents in a fuel among the cylinders of an internal combustion engine comprises a sampling tube 1, having a restriction, e.g., a sintered alumina nozzle, at its inlet end, a member 13 concentric with the sampling tube in which the anti-knock compounds are trapped or deposited, and detachable means in communication with the downstream end of the sampling tube for measuring the flow of exhaust gases.  The inlet of the device is inserted at different points in the exhaust manifold of the engine.  A glass wool filter may be arranged in an enlarged portion of the sampling tube or the tube may comprise perforations 6 and a baffle 12.  The quantity of fuel corresponding to the gas passing through the tube may be calculated from the amount of water condensed in a cooled coil 20; alternatively a flow meter calibrated by this method may be used. Lead and bromine compounds are washed out of the sampling tube and estimated by chemical analysis.

Abstract: 1,178,555. Polyphenylene ethers. GENERAL ELECTRIC CO. 25 April, 1967 [14 Nov.. 1966]. No. 19106/67. Heading C3R. Poly - (2,6 - diaryl - 1,4 - phenylene ether) is obtained by reacting oxygen with a 2,6-diarylphenol, wherein one aryl substituent is phenyl and the other is phenyl, alkyl-substituted phenyl, biphenylyl, terphenylyl or naphthyl, the catalyst being an amine-basic cupric salt complex having a nitrogen-to-copper ratio not greater than 5 to 1, the amine being n-butylamine, di-n-butylamine, tri-n-butylamine, cyclohexylamine, p-menthane-1,8-diamine or an amine of formula where R is hydrogen or methyl and n is 1 or 2, the reaction being carried out at 50‹ to 130‹ C. in a solvent in which the phenol and the complex are dissolved and the water formed in the reaction is removed as fast as it is formed. The complex may be prepared from either a cupric salt or a cuprous salt which can be converted to the cupric state by the oxygen.

Abstract: 893,184. Moderator structures. SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ N.V. May 31, 1960 [June 2, 1959], No. 19219/60. Class 39(4) The fuel rods of a nuclear reactor are surrounded by and spaced from a heat-insulating jacket formed of a finely divided, non- crystalline carbon. The carbon may be prepared either by milling coke or derived from natural gas or petroleum distillates. In a water moderated reactor, cooled by liquid sodium, the wall of the jacket adjoining the cool moderator is pressure resistant and the inner wall is thin. A leak occurring in the inner wall will admit liquid metal to the jacket which will tend to coagulate with the carbon to seal the break. Specification 807,221 and Swiss Specification 286,658 are referred to.

Title: Improvements in or relating to a method and apparatus for monitoring heart rate
IPC: A61B5/0452
Filed: 1969-04-16
Abstract: 1,267,680. Measuring frequency; automatic gain control. COROMETRICS MEDICAL SYSTEMS Inc. 16 April, 1969 [3 May, 1968], No. 19410/69. Headings H3A and H4R. [Also in Divisions G1 and G4] The frequency of a pulse train E, Fig. 4, is measured by binary counters 63 which count clock pulses from a generator 62 between consecutive pulses of train E. The leading edge of a pulse E fires an OSM (one-shot multivibrator) 65 whose output fires another OSM 67 after a fixed delay time. The pulse from OSM 67 resets counters 63 to zero and they then count clock pulses from generator 62. The next pulse E fires OSM 65 which opens gates 64 whereby the count in counters 63 is transferred to storage register 66, followed, after the fixed delay, by a pulse from OSM 67 which resets counters 63 to measure the next interval between the E pulses. The storage elements in register 66 control switching elements 68 to add or remove resistors 69 from parallel paths in a constant current loop, the resistors having a binary relation so that the resultant voltage drop is inversely proportional to the numerical content of register 66, and is therefore proportional to the frequency of pulse train E. The interval between successive pulses E is also measured by a counter 89, Fig. 7, and compared with the immediately preceding interval by means of a subtractor 90, the difference being converted to an analogue voltage signal at 93.  In an automatically gain-controlled amplifier 15, Fig. 3, the output of amplifier 50 is rectified by diode 52 to charge a capacitor 53 and control the input of amplifier 54 feeding a lamp 55 illuminating a photoresistor 51 in the feedback circuit of amplifier 50. Additional rate feedback is supplied from a point further along the circuitry.

Abstract: 1,218,504. Petrol pumps. KIENZLE APPARATE G.m.b.H. 16 April, 1969 [20 April, 1968], No. 19470/69. Heading G4D. The power for resetting the counters of a petrol pump is obtained by stretching a spring when the dispensing hose is hung up. Depression of arm 11 of a composite lever 5 stretches spring 10. A notch on spring-pressed lever 30 engages behind pin 31 on plate 22 which pushes bar 33 to the left, whereby bar 48 disengages projection 43 so that lever 42 cams roller 57 downwards to switch off the pump motor via levers 59, 62, 35. At the same time pin 52 disengages pawl 15 from teeth 14 to allow toothed segment 9 to rotate pinion 8, without having any effect on disc 7, however, because of a one-way drive 16, 8a. Preparatory to the next dispensing operation the dispensing hose is lifted. Spring 10 now drives the composite lever 5 counter-clockwise. Lever 30 swings control plate 22 so that its nose 23 disengages from a slot 20 in the rim of disc 7. Gear sector 9 now drives pinion 8 and disc 7 through 180 degrees, operating slide 25 to set the registers to zero in known manner via arms 27, 29. At this time roller 57 is allowed by cam lever 42 to swing upwards to ,reclose the pump motor switch. Also the nose 23 of control plate 22 falls into the opposite slot 20 on disc 7 so that the control parts resume original positions. In a modification (Figs. 7-9, not shown) the spring may be tensioned by a motor driven cam (65)

The products may be soluble in white spirit, raw or blown linseed oil, stand oil and oil-modified alkyd resins.  They may be cooked with oleoresinous vehicles in known manner or incorporated with alkyd resins during their manufacture or added to the drying oil used to modify such resins.

The additional ammonia added is preferably supplied to the wash tower in the form of aqueous ammonia and may be recycled by recovering ammonia from the wash liquor in known manner.  The wash liquor may be freed from dissolved hydrogen cyanide by the introduction of gases which are insoluble or difficultly soluble in water.  When the hydrogen cyanide being recovered has been synthesized from carbon monoxide and ammonia, the gases employed may be the residual hydrogen and carbon monoxide leaving the separation process.
