Title: Improvements in gear pump assemblies
IPC: F04C11/00
Filed: 1962-01-25
Abstract: 987,587. Valves. C. VOGEL, [trading as W. VOGEL [firm of]]. Jan. 25, 1962 [Jan. 30, 1961], No. 2875/62. Heading F2V. [Also in Division F1] A gear pump unit, particularly in a centralized lubricating installation, comprises an intermediate housing member 6, Fig. 1, mounting on one side an electric motor 5, on its other side a gear pump 7, and housing a pressure relief valve 19, Fig. 2, a combined non-return valve 30 and return flow control valve 36 and a residual pressure control valve 32. The pump driven through a coupling 13 discharges through a bore 15 into a duct 17 and thence through a duct 20 and the non-return valve 30 into the delivery pipe 16. The valve 30 controls through a disc 33 the return flow control valve 36 which controls a transverse bore 38 in a valve housing 31 slidably mounting the residual pressure control valve 32. Normally, when the pump is operating the valve 30 is unseated and the valve 36 closes the bore 38 so that oil is delivered through the pipe 16. On the pressure surge of the pump ceasing, the valve 30 closes and the valve 36 opens so that residual oil in the installation returns through the pipe 16, bore 38 and an axial bore 37, to open the valve 32. Oil can then flow through a return bore 40 which may be closed by a plug 41 or alternatively through a duct 23 and a return bore 24. To close this latter bore a closure screw 42 is replaced by a longer screw. To prime the pump, a duct 45, Fig. 3, opens to atmosphere or the tank and a loose-ball 46 co-operates with a duct 43. So long as air is pumped, air escapes through the duct 45. On oil being pumped the ball closes the duct 45 so that the pump delivers to the bore 15. Screwed plugs 26, 35 permit the easy removal of the valve parts for servicing.

Title: Refuse Incinerator
IPC: F23G5/32
Filed: 1967-01-19
Abstract: 1,172,571. Refuse incinerators. DORR-OLIVER Inc. 19 Jan., 1967 [3 Feb., 1966], No. 2907/67. Heading F4B. A refuse incinerator having an outer refractory housing 24 and a stainless steel cylinder 23 is fed with sewage sludge under pressure through a nozzle 14, the combination of a compressed-air tube 21, motor 47 and end-plate 17 providing a rotating fan-shaped spray of sludge progressively spraying an entire circumferential zone of said cylinder 23. A tangential pipe 26 forces hot combustion gases around the steel cylinder 23 in the space 28 between the housing and the cylinder, heating said cylinder and igniting the dried sludge inside, until, in combination with preheated secondary air, the gas enters through opening 29 in the cylinder wall, to complete the combustion of the sludge. An exhaust outlet 37, connected to a cyclone, removes the combustion gases and the ash of the refuse, leaving only the oversize particles which disintegrate in the raceway formed by the annular projection 42 and the cylinder wall. The end walls of the housing are spaced apart by the length of the cylinder when cold plus the amount of thermal expansion of the cylinder when at combustion temperature, eliminating leakage of combustion gases when the cylinder is expanded. When the cylinder is cold, leakage is avoided by a spring 52 resiliently pressing the ends of the cylinder together. A pyrometer 56 can be used to record the temperature in space 28.

Compounds wherein R1 is mercapto may be prepared by reacting CS2 with a compound of formula <FORM:0874204/IV (b)/3> in the presence of a secondary or tertiary organic base and an alcohol as diluent.  Compounds in which R1 is alkylthio or aralkylthio may be obtained by treating the corresponding alkali metal mercaptide with a molecular equivalent of an alkylating or aralkylating agent. Compounds of the first formula in which R1 is hydrogen may be prepared by the catalytic reduction of the corresponding mercapto compound with a Raney nickel catalyst containing adsorbed hydrogen. Compounds of the first formula given above wherein R1 is hydrogen and R2 and R3 together make up the residue of a benzene ring may be prepared by the reaction of formic acid (or, according to the first Provisional Specification, an anhydride of an aliphatic or aromatic carboxylic acid) with a compound of formula <FORM:0874204/IV (b)/4> Compounds of the first formula given above wherein R1 is alkylthio or aralkylthio may be obtained by heating to a temperature above its melting point a compound of formula <FORM:0874204/IV (b)/5> where R4 is alkyl or aralkyl; these compounds, when boiled in glacial acetic acid, yield compounds of the first formula given above (R1 being alkylthio or aralkylthio).  According to the first Provisional Specification, when R2 and R3 together make up a benzene residue, R1 may also be alkyl, aralkyl or aryl; these values for R1 do not appear in the Complete Specification; these compounds may be prepared by reacting 2-hydrazino-4-hydroxyquinoazoline with formic acid or an anhydride of an aliphatic or aromatic carboxylic acid; and an additional example is given.  The triethylamine salt of 2-(4-methyl-6-hydroxy-2-pyrimidyl)-dithiocarbazinic acid is obtained as a by-product when reacting 4-methyl-6-hydroxy-2-pyrimidylhydrazine with CS2, methanol and triethylamine.  It is methylated with methyl iodide to yield 4-methyl-6-hydroxy-2[bis(methylthio)methylene hydrazino] -pyrimidine.  The compounds of the invention are used in photographic silver halide emulsions (see Group XX).  Specifications 851,815 and 851,816 are referred to.

Filed: 1969-01-20
Abstract: 1,206,573. Selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 Jan., 1969, No. 3094/69. Heading G4H.  In a displacement measuring system of the type in which two detectors (photoelectric cells) produce quadrature spaced pulse trains which are processed to apply pulses to forward or backward inputs of a counter which thereby indicates the resultant displacement, compensation for ageing of the detectors-which results in asymmetry in each pulse train (i.e. a mark/ space ratio different from unity) and incorrect operation of the processing circuits-is effected either by applying a bias voltage to each detector or by arranging each detector in a bridge and varying the impedance in one of the bridge arms, in such a way that any asymmetry is removed, the necessary control for this being effected, for each detector, by comparing the average D.C. level of the resulting pulse train So with that of its inverse S o  in a transistor longtailed pair 5 (Fig. 3, not shown), this comparison only being operative when the counter is being stepped sufficiently rapidly which is detected by mixing T, the forward T and backward H counting pulses and using the integrated and smoothed output to control the impedance T 4  in the tail of the comparator. In this way no attempt at compensation is made when the member whose displacement is being measured is either stationary or moving very slowly.

Abstract: 1293641 Pressurized dispensing containers COSTER TECNOLOGIE SPECIALI S p A 22 Jan 1970 [30 Jan 1969] 3201/70 Heading F1R A double valve assembly for a pressurized double container package dispenses a mixture of two liquids or one only of the two, depending on whether the valve actuator is tilted or axially moved respectively. Axial movement opens one valve while the other is held on its seat. During filling the other valve is positively held on its seat. As shown, a deformable receptacle 18 is secured to a body 4 of the valve and the combined assembly, mounted on a cup 1, is mounted on the container 2. The valve comprises plugs 6 and 7, the plug 6 having a recess into which project guide ribs 11, for securing the stem 12 therein, and which define passages therebetween. A recess 8 is provided in plug 7 which co-operates with the projected end 9 of plug 6. Depressing the stem 12 axially downwards causes the plug 6 to move towards plug 7, the end 9 of plug 6 abutting the lower surface of recess 8 in plug 7 thus preventing any further axial movement, and the outer container is opened to the atmosphere via the valve chamber, passages defined by ribs 11 and the discharge passage provided in the stem. In this position the plug 7, overlying the orifice 14, is held firmly against the inner lower surface of the valve body 4 closing the orifice 14 from the valve chamber. When the stem 12 is tilted, the force is transmitted to the plug 7 causing it to tilt on its edge thus opening the orifice 14 to the chamber and the mixture of the two liquids to be dispensed. When the mixture is to be dispensed a button 20 having one or more teeth 22 which cause tilting of the stem on depression, is fitted.

Title: A pulse-modulated doppler-type electro-magnetic detection system
IPC: G01S7/285
Filed: 1969-01-22
Abstract: 1,253,551. Radar. THOMSON CSF. 22 Jan., 1969 [23 Jan., 1968], No. 3682/69. Heading H4D.  In a pulsed doppler radar operating over a predetermined doppler frequency range, the carrier frequency fs, the local frequency fo, the intermediate frequency f 1  = fs#fo and the pulse frequency ft are all produced by frequency multiplying or dividing, the output of a single oscillator, such that said carrier, local, intermediate and pulse frequencies have a common aliquot part, which is chosen greater than the upper limit of said predetermined doppler frequency range. By this selection it is ensured that any interference signals produced in the radar receiver, by the beating together of any of the above mentioned frequencies, will have a frequency which does not pass into the doppler signal processing circuit. In the arrangement of Fig. 2 the pilot oscillator 21 produces a signal, at frequency f Q . This is frequency divided in means 22 by factor i, to give the intermediate frequency f I , and is further divided in means 25 by factor t/i, to give the pulse frequency ft. Thus:- The pulse frequency is further divided in means 26 by factor n/t, to give frequency f I /n. This frequency is fed to an input of frequency shift means 23, having the frequency f Q  applied to its other input. Means 23, which may be a suppressed carrier single side band modulator, produces frequency f Q +f I /n. The carrier frequency fs = nf Q  and the local frequency fo = fs+f I  = nf Q +f1. The outputs of oscillator 21 and shift means 23 are thus alternatively gated through means 24, under the control of the pulse frequency, during the transmission and waiting intervals respectively, to a frequency multiplier 27, using the factor n. Signals fs and fo are thus fed during their correct periods to the pulse modulator 111 and the receiver mixer 15 respectively. The I.F. amplifier 17 is disabled during the transmission period, by the pulse frequency. The intermediate frequency fl is fed to the phase detector 18. The common aliquot part of the above frequencies, is the pulse frequency ft and is chosen as described. In the embodiment of Fig. 3 (not shown) the pilot oscillator operates of the intermediate frequency f I , and the carrier fs and local fo frequencies are produced by individual multipliers operating with respective factors n and (n+1).
