Title: Method fo protecting metals against atmospheric corrosion
IPC: C23F11/02
Filed: 1973-11-09
Abstract: 1414025 A method of protecting metal objects against corrosion INSTITUT FIZICHESKOI KHIMII AKADEMII NAUK SSSR 9 Nov 1973 52027/73 Heading B8C A method of protecting the surfaces of metal products, e.g. of complex configuration, against atmospheric corrosion by vapour phase inhibitors in a sealed space, is characterized in that a porous carrier is located in said space, the carrier being a silica gel, or a zeolite and containing a vapour phase inhibitor, in the form of a primary, secondary or tertiary amine, a mixture of amines, or derivatives of amines. The silica gels and zeolites, which have a high adsorbtional capacity, provide a large store of vapour phase inhibitor with a small volume of porous carrier, the silica gels and zeolites having pores of a diameter from 20-140 Š and 4-15 Š, respectively. Primary amines-cyclohexylamine, benzylamine; secondary amines-hexaethyleneamine, dicyclohexylamine; tertiary aminestriethylamine, cyclohexylamine carbonate, as well as mixtures of these amines, are used. The silica gels and zeolite are dried at 200- 300‹ C., cooled in a closed vessel up to 15.20‹ C., and then immersed in the vapour phase inhibitor or, in its solution, in an organic solvent such as spirits, or acetone, the released heat being allowed to escape. The inhibitor, or its solution, may be applied to the carrier in portions up to complete saturation, any excess amount being removed by way of natural drying, or by passing the carrier through absorbent rollers. The silica gel, or zeolite, loaded with vapour phase inhibitor, can be placed in perforated cartridges which are made of glass, cardboard &c., which does not interact with the inhibitor. The cartridges are adapted, e.g. to be placed into the cavity of a steam boiler, kept in storage as a reserve for a long time or to be placed in a polyethylene container which sealingly contains, e.g., a number of tightlypacked, electronic, precision instruments.

Title: Improvements in and relating to governors
IPC: F02D41/38
Filed: 1969-10-27
Abstract: 1281090 Automatic control of speed ROBERT BOSCH GmbH 27 Oct 1969 [25 Oct 1968 (2) 7 Nov 1968] 52462/69 Heading G3R An electronic governor for an internalcombustion engine, e.g. a diesel, comprises a regulator having an operational amplifier 27 having non-inverting and inverting input terminals, to the latter of which is connected an engine speed signal and a feedback network R which determines the governor characteristics. As shown, a speed reference voltage from a pedal operated potentiometer is applied to the non-inverting input 29 and a voltage from a tachogenerator is applied to a speed input 33. The tachogenerator may produce pulses or an A. C. signal whose frequency is proportional to speed, and this is converted to a D.C. voltage by an RC circuit Figs. 2 and 3 (not shown). In the feedback network shown a capacitor 36 provides a differential component and a potentiometer 38 controls the slope of the speed/fuel supply characteristic. The output of 27 controls the fuel injector by an electrohydraulic system of an electric servomotor, and injector position feedback is provided. A number of alternative embodiments are described Figs. 7... 20 (not shown) for operating governors which control speed throughout the range and/ or the idling and maximum speed characteristics only and include arrangements for producing non- linear features such as a kink in the idling characteristic. This is produced by a diode circuit whose conduction is determined by an adjustable resistor network Fig. 7 (not shown) or an auxiliary voltage source, Fig. 10 (not shown). Also positive feedback may be used to produce a positive slope to the load limiting characteristic, Fig. 11 (not shown) and a further diode circuit used for temperature compensation, Fig. 17 (not shown). In Figs. 21 to 32 (not shown) separate amplifiers are connected in parallel with the main amplifier to produce the required characteristics, and these are further modified by various transistor circuits between the tachogenerator and the amplifier input.

Abstract: 1,075,340. Rotary vacuum-pumps. CENCO INSTRUMENTS CORPORATION. Dec. 29, 1964 [July 22, 1964], No. 52713/64. Heading F1F. [Also in Division F2] A rotary vacuum-pump of the outwardly-sliding radial-vane type comprises a low-pressure stage 22 and a high-pressure stage 24 with a plate 24 therebetween, the two stages being sealed by oil situated in a space 32 externally thereof. The stage 24 includes an intake port (49), Fig. 7 (not shown), which is connected to a cylindrical chamber (48) containing a pumping rotor (50) by a hollow block (47), and an exhaust port (72) connected to an intake port (95), Figs. 1 and 8 (not shown), for a cylindrical chamber (90) containing a pumping rotor (93) in the stage 24 by an opening (88) in the plate 26, an exhaust port (94) for the chamber (90) being controlled by a non-return valve (96), Fig. 4 (not shown), (see Division F2). The rotors (50, 93) are attached to a common driving-shaft 33 and are made hollow so that oil for sealing and cooling purposes can pass therethrough, the oil being taken from the space 32 by the action of the rotors through a hole 116 in a hollow end-cap 112 attached to an end-plate 110 for the stage 24, a passage 120 in said endplate, a passage 104 in the plate 26 and a passage 126 in an end-plate 82 for the stage 22, which passage communicates with the interior of a hollow end-cap 122 attached to the plate 82. While oil passes through interior of the rotor (93) gas mixed therewith is ejected by centrifugal action and escapes into the opening (88) through a groove (130), Figs. 1 and 4, in the plate 26. Sealing of a pair of diametrally-opposed radialvanes 52, 53 in each rotor is effected by centrifugal displacement of the oil within the rotor, surplus oil on the exterior portions of the rotor and the vanes being entrained with the gases being pumped. Gases and oil entrained therewith that are discharged from the stage 24 through the port (94) enter the space 32 whence the gases escape through a cowl or bonnet attached to a portion 29 of an external housing for the stages. The stage 22 may be charged with ballasting gases e. g. air, at atmospheric pressure through a pipe 36. Pressure-relief valves 86, (86') are provided on the plates 82, 110 at the ends of passages 84, (84') communicating with the ports (72, 95), respectively. The vanes are biased outwardly in a radial direction by springs 68 mounted on pins 67 attached to a tongue or so called leg 65 on one of the vanes in each pair thereof, said pins being slidingly engaged by radial bores in a tongue on the other vane. The tongues 65 engage with slots 70 in the shaft 33. The pump may be modified to include additional stages operating in parallel with the stages 22, 24.

The process may be carried out continuously using as seed crystals, crystals taken from a previous crystallization and recrystallization may be accelerated by blowing warm dry air on to the surface of the mass to evaporate water therefrom during crystallisation. The rate of crystallisation of fructose may be increased by the addition to the solution of 2-4% by weight, based on the sugar solids, of methanol, ethanol, and/or isopropanol.

Title: Apparatus for making a tabe by helically winding an elogate strip
IPC: B21C37/12
Filed: 1977-12-23
Abstract: The apparatus serves for the production of tubes by winding up a strip, in particular a strip of sheet metal, helically using a winding device. To guide the strip (1) in a circle to form a strip coil (10), this winding device (7) has two joining rollers (5, 6), which are arranged at the strip entry point, engage on the two broad sides of the strip (1) and join together the strip coils (10) adjacent to one another in the tube. In order to be able to produce tubes in precisely the desired, constant or varying, diameter with this apparatus, the peripheral speed of one joining roller can be varied relative to that of the other joining roller. Thus, the joining roller on the inside of the strip coil can be varied in its rotational speed and the joining roller on the outside of this coil can be driven at a constant rotational speed. <IMAGE>
