Title: Method of highly concentrating sulfuric acid, and apparatus therefor
IPC: C01B17/88
Filed: 1960-08-05
Abstract: 940,656. Concentrating sulphuric acid. APPAREILS ET EVAPORATEURS KESTNER. Aug. 5, 1960 [Aug. 13, 1959], No. 27198/60. Heading BIB. Sulphuric acid is concentrated up to 95% H 2  S04 in a multi-stage process, the first stage or stages being carried out by heating the acid under a vacuum of 60 mm. Hg absolute until the concentration is 85 % H 2  SO 4 , the final stage being carried out by heating the 85% acid under a vacuum of 10 mm. Hg absolute or less, and passing the vapours from the final stage into a condenser where -the vapours are brought into direct contact with cool sulphuric acid, which is maintained in circulation through cooling- means and the condenser. In the apparatus shown, first-stage heater 16 is maintained at 155 ‹C. and is evacuated by pump 20, which is connected to the heater via surface condenser 18 and liquid/vapour separator 17. The second heater 21 is maintained at 175 ‹C. and is connected via separator 22 to direct-contact condenser 23 which is evacuated by ejector 29. The acid product (95% H 2  SO 4 ) is collected in receiver 28. The mixture of steam and sulphuric acid vapours flows from separator 22 into condenser 23 where it is contacted with 64% H 2  SO 4  which is pumped into the lower part of the condenser from receiver 30 via cooler 24, which cools the acid to 35 ‹C. Owing to the condensation of the vapours the coolant-acid becomes diluted, and it is maintained at 64% H 2  SO 4  by pumping some of the 95% H 2  SO 4 , from receiver 28, into the top of the condenser via cooler 27. The excess 64% H 2  SO 4  from receiver 30 is recycled to feed-tank 11 via line 13. If the strength of the feed-acid exceeds 64%, it is supplied to the circuit of condenser 23, instead of being introduced into the system through line 12.

Title: Improvements in exhaust driven accessories for internal combustion engines
IPC: F01D17/14
Filed: 1934-09-24
Abstract: 440,286. Elastic - fluid turbines. ELLOR, J. E., Grandell, South Drive, Chain Lane, Mickleover, Derby. Sept. 24, 1934, No. 27369. [Class 110 (iii)] The effective area of the nozzles of a turbine driven by the exhaust from a reciprocating internal-combustion engine is increased after the high initial pressure stage has passed in order to allow the gases to be evacuated without back pressure during the subsequent stages of exhaust. The increase is effected by the withdrawal of obturators d<1> from the nozzles d3. The obturators are withdrawn against the pressure of springs d<4> by a cam actuated linkage f<1>, f<2>, f3. With a six cylinder engine four nozzles in 'each half of the turbine casing are connected to the manifold of three cylinders. Three of the four nozzles are provided with obturators which are worked in unison by the linkage.

[Also in Groups XXII, XXIII and XXXV] A brush-making machine (see Group XXIII) comprises photo-electric controls for the tufting tool and for the bristle feeding head. The main shaft of the machine carries a disc 200a rotating between a lamp 203a and a photo-electric cell 202a and provided with two apertures 201a so that two pulses are produced at the output of the cell for each revolution of the disc. These pulses are amplified in a device 204a and applied to a bi-stable circuit 205a the output of which is fed to a differential amplifier 207a. This causes a rectifier circuit 208a to pass a current through the operating winding 412 of the tufting tool in direction i 1  or i 2  according to the condition of the bi-stable circuit. In Fig. 2 a bristle layer 11 is fed to the tufting tool by means of motors 26, 27 in lengths controlled by a photo-electric cell and apertured disc arrangement 30, 31, 32 which it is suggested could co-operate with an electronic cumulative counter-arrangement.
