Title: Process and apparatus for the purification of water
IPC: C02F5/02
Filed: 1930-04-28
Abstract: 360,384. Purifying water ; gravity - separation apparatus. SOC. G•N•RALE D'EVAPORATION PROC•D•S PRACHE ET BOUILLON. 25, Rue de la PepiniÞre, Paris. April 28, 1930, No. 13078. Convention date, April 29, 1929. Void [Published under Sect. 91 of the Acts]. [Class 46]. In a process for the purification of water, the water and suitable chemical reagents are intensively mixed in the presence of steam and then subjected to a reduction of pressure which causes intense ebullition. The mixture of gas and vapour thus obtained is used to heat the incoming water while the non-vaporized water is decanted to remove precipitates. Two forms of apparatus are described. In Fig. 1 the water enters the apparatus by the tube 10, steam by the tube 12, and chemical reagents by the tube 31 from the tank 32. The mixture is circulated through the tank 1 by the propeller 3 and finally leaves by the valve 18 and passes into the receptacle 19 through the atomizer 20. Here it is partly vaporized and the mixture of gas and vapour passes to the condenser 23, heats the water supplied by the tube 26, and is removed by the pump 25. The unvaporized water in the receptacle 19 is led by the tube 28 to the decantation tank 29. In Fig. 2 the cold water from the tank 33 is heated in the heater 34 and flows on to the wheel 37 which regulates the supply of reagent from the hopper 40. The water and reagent are mixed in the tank 39 and then led by the pump 45 into the receptacle 46 from which they fall in cascades over the baffles 48 in the presence of steam admitted by the pipe 50. The pump 53 sucks the mixture up the tube 51 where it is atomized and the gas and vapour pass through the heater 34. Most of the unvaporized water in the tower 47<1> passes back to the tank 39 by the tube 58, while a fraction overflows through the tube 59 to the decantation tank 60 from which deposits are removed through the cock 61 controlled by the float 62. Excess steam passes through the tube 64 to the heater 34.

Title: Improvements in or relating to alkylene cyanohydrins and method of producing same
Filed: 1947-05-15
Abstract: Alkylene cyanohydrins are prepared by reacting alkylene oxides with hydrocyanic acid in the liquid phase and at a temperature of 50-100 DEG  C. in the presence of amine catalysts of the type <FORM:0630929/IV (b)/1> where R and R1 are alkyl radicals with 4 or less carbon atoms, R11 is hydrogen or an alkyl radical with 4 or less carbon atoms and R111 is hydrogen or a hydroxyalkyl or alkyl radical having 4 or less carbon atoms.  In working up the reaction product the amine catalyst is distilled off with the water, recovered and recycled.  In the preferred method the alkylene cyanohydrin and water are passed through reaction tubes heated to the necessary temperature, the alkylene oxide water and the catalyst are fed into the system and the crude product withdrawn continuously.  The product is distilled at normal pressure to remove the water and amine catalyst and then at reduced pressure to give the alkylene cyanohydrin.  The water and amine are recyled or the amine recovered by separation or distillation and recyled.  Examples are given using ethylene and propylene oxides, and di-isopropyl amine, di-sec-butylamine, di-isopropyl-b -hydroxy ethyl amine, di-iso-propyl ethyl amine and di-isopropyl methyl amine as catalysts.

IPC: B08B9/44
Filed: 1927-05-16
Abstract: 297,399. Marks, E. C. R., (Meyer Manufacturing Co., G. J.). May 16, 1927. Bottles, washing.- In a bottle-cleaning machine, the bottles are pushed from a loading table 30 into holders 28 in a conveyer which passes the bottles through a soaking tank 32, then over rinsing sprays and between rotary brushes for cleaning the exterior of the bottles, then over rotary brushes 35 which enter the bottles and finally, after the bottles have been rinsed, they are delivered on to an unloading table 60 adjacent to the loading table. Means are provided for yieldingly supporting the bottles against breakage and obstruction and for permitting varying sizes of bottles to be cleaned. The loading table 30 pivotally and adjustably mounted in the machine frame and pressed upwardly at its front end against adjustable stops, by means of springs 44, is provided with troughs for a row of bottles and with slots to permit rods 50 to push the bottles from the table into a row of bottle-holder 28 in .an intermittently-moving conveyer. The rods 50 are secured to a shaft 49 which is adapted to be rocked in one direction by means of a driven cam wheel 56 acting through linkage 57 and in the reverse direction by a counterweight 54. The effect of the counterweight may be assisted by means of a spring-pressed rod 72 tending to raise a pivoted unloading frame 62 about its pivots whereby an arm 67, with a slotted end 68 engaging a pin on a lever 70 secured to the shaft 49, acts to rock the shaft 49. The upward movement of the rod 72 transfers bottles from an unloading table 60 to a conveyer 74. The bottles on the conveyer as they arrive at the unloading position are pushed from their holders by means of a bar 58 carried by rocking arms 59, the bar being adapted to engage the necks of the bottles. For driving the machine, a motor 82 is provided on the frame.

Patent GB-135297-A (GB)
IPC: H01H19/18
Abstract: 135,297. Horn, J. Nov. 21, 1918. Switches, actuating; switches, quick-action. - Relates to mechanism for periodically and automtically reversing electric switches &c., and consists of a series of actuators and means automatically movable relatively to said actuators to successively operate the same to cause actuation of the switches or the like, the movement of the said means being automatically stopped at the completion of the operation of said actuators and automatically restarted to again operate said actuators after a predetermined period of rest. As shown, regenerator furnace valves are automatically reversed at fifteen minute intervals by piston-rods 14 in cylinders supplied with fluid by valves operated by members 24 engaged by a tappet 29 when a nut 25 travels along a screw thread 26 driven by a motor 31. In the motor circuit contact is made at 36, 37 by cams 35, 35' on an arbor 33 rotating once per hour. At the end of the travel of the nut 25, when all the valves have been reversed, a member 43 on the nut shifts a rod 39 and breaks the motor circuit at one of two pairs of contacts 41, 42 causing the nut 25 to rest. At the same time the electric contact is completed at the other pair of contacts 41 or 42 so that the nut 25 commences its reverse travel immediately contact is made at 36 or 37. The screw 26 may rotate always in the same direction, the threads being then reversible. In a modification, the members 24 control electric switches instead of valves, a switch blade 60, Fig. 4, bridging one of two pairs of terminals 61, 62, the blade being held against the contacts by a pivoted telescopic spring-link 63.

Abstract: 774,376. Measurement of vibrations. RUSTON & HORNSBY, Ltd. June 2, 1954 [May 15, 1953], No. 13723/53. Class 40 (1). In an electronic instrument for measuring amplitude of mechanical vibrations, e.g. of a crankshaft, including a pick-up for converting them to electrical potentials, an amplifier to which these potentials are applied and an indicator, comprising a peak reading voltmeter, fed by the amplifier, power for said voltmeter is supplied from a low-tension battery through a vibrator and transformer combination. The output of a pick-up is amplified in valves V1, V2 and then applied either directly or through a unity gain integrator stage V3 according to the position of switch SW2 to a peak reading valve voltmeter (Fig. 3) and to the Y plates of a monitoring electrostatic cathode-ray tube (Fig. 2, not shown), using a known time base circuit. The valve voltmeter comprises a pair of triodes V4, V5, the cathodes of which are connected through D.C. meter M1 and one of the range resistors CR1, CR2, CR3. The grids are fed via blocking capacitor C18 and a double diode balancing circuit, the peak voltage being built up on capacitor C20 which forms part of the load of diode D2. The corresponding changes in cathode potential of V4 are measured by the meter to give a measure of vibration amplitude. The H.T. for valves V4, V5 and V1 is stabilized by regulator tubes REG3, REG2 respectively. The CRT time base may be synchronized with the vibration frequency by means of shorting contacts in that circuit driven by the crankshaft. The power unit including the vibrator and transformer is shown in Fig. 5.
