Title: Improvements in or relating to corrosion inhibition
Inventor: DENMAN WAYNE L
IPC: C23F11/14
Filed: 1959-03-10
Abstract: 859,074. Preventing corrosion. DEARBORN CHEMICAL CO. March 10, 1959, No. 8258/59. Class 123(1) Metal water pipes and tanks are protected from corrosion by adding to the water flowing in the pipes or held in the tanks an inhibitor consisting of from 1 to 20 parts by weight of an aliphatic amine carried in an aqueous emulsion which is stabilized by the presence of one part by weight of water soluble condensate of at least 5 mols of ethylene oxide with an aliphatic amine, each aliphatic radicle being a C 12 -C 20  hydrocarbon radicle. The inhibitor is added to the water in a concentration sufficient to form a protective film on the metal but not exceeding 100 parts per million for each ingredient. The preferred amine both for use as the first ingredient and in the formation of the second is octadecyl amine. To give the desired water solubility and best emulsifying properties of the condensation product from 40-60 mols of ethylene oxide are combined with one mol of the octadecyl amine. To protect metal surfaces, e.g. of a tank, above the water level from corrosion a small amount of a vapour phase inhibitor such as cyclohexyl amine or morpholine may be incorporated into the inhibitor.

A blast finishing machine comprises a casing, an endless workpiece support belt disposed within said casing and guided and supported upon roller devices and driven to rotate so as to provide a workpiece support pocket subjecting supported workpieces to tumbling action therein, a blast media projection device directed inwardly of said casing and in the direction of workpieces supported upon said belt, and an alternative workpiece support device adapted to be detachably mounted upon said casing to extend inwardly thereof and having at its inner end a rotatable table device and adapted to support workpieces and to present them to the direction of projection of blast media into said casing while being rotated. Within a casing 1 a belt 2 travels round rollers 3, 4, 5 and round laterally spaced side discs 6, 6. Workpieces being tumbled in the trough so formed are blasted by abrasive or other medium entering through opening 7. The belt may be an endless rubber belt or may comprise a series of articulated metal plates; it has perforations 26 to permit spent blast-out to fall therethrough. The casing 1 has an access door 8 provided with bearings 9, 9 receiving a pivot portion 10 of an arm 11 terminating in a stub axle 12. The latter rotatably supports the hub 13 of a device comprising a drive-wheel 14 and a bracket 15 within which is removably supported an open-top basket 16 for workpieces. A spring 19 acts on the arm 11 to hold the drive wheel 14 in contact with one side disc 6 whereby the basket 16 is rotated. A flat tube may be used instead of the basket 16. The drive may include gearing; alternatively the vertical portion of the arm 11 may be adjustable in length so as to vary the position where the drive wheel 14 contacts the side disc 6, so as to vary the speed. The mounting of the device on the door 8 facilitates loading and unloading. The pivot pin 10 may be carried by bearing devices arranged so as to incline the pin away from the vertical while still being parallel to the door 8, the workpiece support table and basket 16 being correspondingly inclined away from the vertical. The drive wheel 14 will be held by gravity against a side disc 6 so that the spring 19 can be omitted. Several modifications are described.

Abstract: 1388612 Supply circuits for flash lamps GENERAL ELECTRIC CO 28 Feb 1972 [24 March 1971] 9173/72 Heading H2H [Also in Division G2] A photo flash circuit comprises a flash lamp 26 connected in series with an arc gap 33 and a source 11 for supplying a firing pulse to the series combination. The source 11 includes a piezoelectric element 12 provided with electrodes 13, 14 and an impactor 18 connected by a spring 19 to a support 20 which is carried by a camera housing or in a shutter mechanism. The element 12 is made of barium titanate, lead metaniobate or lead-zirconium-titanate and when the camera shutter is opened, the impactor 18 strikes the element to provide a high voltage pulse. The high voltage breaks down the arc gap 33 to cause the lamp 26, which contains shredded metal foil 27, to flash. Additional lamps such as 26<SP>1</SP> may be connected in parallel with the lamp 26 so that each firing pulse flashes the remaining lamp with the lowest flashing voltage characteristic. In a modification each lamp is connected to a respective arc gap, the arc gaps breaking down at different voltages to enable sequential flashing of the lamps. Alternatively the spark gaps may break down at the same voltage but are connected in series for sequential flashing of the lamps.

Abstract: 959,316. Amplifiers; reducing generation of a specified harmonic. STANDARD TELEPHONES & CABLES Ltd. March 14, 1961, No. 9305/61. Headings H3W and H4R. In a signal transmission arrangement there are derived from an input signal two signal components, each corresponding to the input signal and each in phase with the other, the level of one signal component is changed by attenuation or amplification, and both components are then separately amplified by identical amplifiers, whereafter the output of the amplifier to which the higher level component was applied is attenuated to bring the voltages of a particular harmonic to the same values as those present in the output of the other amplifier, the phase of one of the output voltages is reversed and the two are combined, thus removing the voltages of that particular harmonic from the resulting signal. As shown, an incoming signal is applied to an equal ratio hybrid coil 2 to produce equal in-phase components 3 and 4 which are amplified in identical amplifiers 7 and 9, the first component 3 being attenuated by L db at 5, and the second by nL ab at 11, where the nth harmonic is the one to be removed. The output of 11 is phase-reversed by the 1 : 1 zero loss transformer 12 and the components are recombined by the equal ratio hybrid coil 14. It is stated that the nth harmonic voltage at 10 exceeds that at 8 by nL db, so that the nth harmonic is not present at 15. In a second embodiment (Fig. 2, not shown), the attenuators 5 and 11 are omitted, the second signal is amplified prior to its application to the amplifier 9 and the different losses necessary are introduced by the use of an unequal ratio hybrid coil in place of coil 14.
