Title: Improved method of and apparatus for counteracting undesired magnetic fields
IPC: G01C17/38
Filed: 1928-03-02
Abstract: 286,277. Pioneer Instrument Co., Inc., (Assignees of Titterington, M. M.). March 2, 1927, [Convention date]. Magnets. - An undesired magnetic field is counteracted by setting up an external field which is the resultant of two coaxial and opposed fields. Such a field is preferably produced by a magnet having consequent poles, e.g. a South pole at each end and a North pole at its centre, the relative intensities of the two fields being adjustable by axial displacement of an iron &c. sleeve surrounding the magnet. The Figures show the invention applied to the correction of a magnetic compass for semicircular and heeling errors. In Fig. 1 two magnets 21, 22, each of the above kind, are arranged at right angles to each other in a casing 19 below the compass 16. The magnets are clamped within rotatable bushes 23, and are keyed within externally-threaded sleeves 28 passing through fixed nuts 29. The sleeves can thus be displaced along the magnets by turning the heads 24. The casing 19 may be provided with a downward extension containing a third, vertically-disposed, correcting magnet similar to the magnets 21, 22. In a modifica- Lion, Fig. 5, a single correcting-magnet 46 is mounted in a casing 40, which can be rotated relatively to the compass 37, the magnet being externally threaded to receive the internallythreaded sleeve 47. In using the device shown in Fig. 1, the aircraft &c. carrying the compass is turned so as to be headed due north, and any compass error is annulled by adjusting the sleeve 28 over the magnet 22 which then lies east and west. The aircraft is then turned through 90‹ and the error annulled by adjustment of the sleeve on the magnet 21. The vertical correcting-magnet, when used, is adjusted when the aircraft is tilted in relation to the horizontal plane. In using the form shown in Fig. 5, the setting of the casing 40 is ascertained from a. graph showing the compass error in various azimuths.

Filed: 1916-05-09
Abstract: 104,957. Baker, G. R., and Owen, J. W. May 9, 1916. Dough dividing and working machines; rolling-machines.-Dough is mixed with a fermenting-agent, and then, without proving, is sheeted and folded a large number of times in succession, each sheeting and folding being effected at right angles to that preceding. The complete process of making bread by this method is diagrammatically shown in Fig. 2. The dough, which has been mixed with yeast and preferably with an acid substance such as cream of tartar, is kneaded in kneaders 2, and then transferred to a dividing and handing-up machine 3, from which the separate pieces are carried by an elevator 4 to two bucket conveyers 5 delivering the pieces to two sheeting and folding machines 7 of the type described below, from which the conveyers 8, 8<a> lead them to other conveyers 9 which bring them all to one moulding machine 10. This may be of the kind shown in Specification 17598/12. The moulded pieces are then put into tins, and the tins are carried by a conveyer 11 to a prover 12 of any known kind, and thence pass into a travelling oven 13. After leaving this oven, the loaves are removed from the tins, passed down a slide 14 and carried by conveyers 15, 17 to the bread-room, the tins being returned by a shoot 18, conveyer 19, shoot 20, and conveyer 21 to a receiving-bench 22. To perform the special sheeting and folding operation, the apparatus shown in Fig. 3 is employed- A feed-band 29 carries definite portions of the dough to a pair of rollers 30 at the top of the machine, whence each piece falls and folds upon an intermittently-driven web 31, to be then transferred to a second pair of rolls 32 at right-angles to the first. Again falling in a folded sheet upon another web 33, it is carried to a third pair of rollers 34 at right-angles to the second pair. Proceeding thus, it is carried bv webs to rollers 35, 37, 39, 41, 42, each pair of rollers being at right angles to the preceding pair. Falling upon the last belt 43, it is carried first between belts 8, 8<a>, and then, on the level part of 8<a>, below a flexible board or plate 8<b> of a known kind for coiling the dough and thence to the moulding-machine. Each pairs of rollers is adjustable for distance apart, and each web for tension. The rollers and the webs may be driven by the gearing shown from the shaft 45, the rollers being driven continuously, and the webs intermittently.

Title: Improvements in or relating to blocking oscillators
IPC: H03K4/16
Filed: 1951-03-30
Abstract: 683,109. Saw-tooth generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 30, 1951 [April 4, 1950], No. 7433/51. Class 40 (vi). A blocking oscillator for generating saw-tooth voltages comprises a discharge tube having an output electrode transformer coupled to the control grid, the control grid winding being connected in series with a capacitor, one side of which is connected to cathode, and the voltage across which is applied to a second grid located between the control grid and output electrode. In this way the amplitude of the saw-tooth voltage produced across the capacitor is maintained constant with changes on the frequency of the blocking oscillator. The Figure shows a blocking oscillator in which the voltage generated across the grid capacitor 6 is applied directly to the suppressor grid 8 so that when the negative charge on capacitor 6 increases the anode current of the valve 1 is cut-off by the negative suppressor grid voltage before the control grid potential has fallen sufficiently to render the valve non-conductive. Thus the maximum and minimum values of the saw-tooth voltage are determined by the control-grid voltage/ anode current and suppressor-grid voltage/ anode current characteristics respectively of the valve. In a modification, Fig. 2 (not shown), the suppressor grid is biased from an external source and is capacitatively coupled to the grid capacitor.
Patent GB-794619-A (GB)
Title: Composition of lubricating greases
Filed: 1956-03-12
Abstract: A lubricating grease comprises a lubricating oil, a grease-making proportion of a metal soap and a minor proportion of a reaction product of an alkylene oxide with a resinous alkyl phenol-aldehyde-ammonia condensation product.  The lubricating oil may be mineral or synthetic, while the soap may be alkali metal or alkaline earth metal, particularly sodium or lithium, soap of a fatty acid derived from animal, marine or vegetable oils or from the oxidation of hydrocarbons.  The grease may also contain adhesion-improving agents, anti-rust agents and extreme pressure agents.  In the examples, a reaction product of ethylene oxide with a resinous octyl phenol-trioxymethylene-ammonia condensation product is added to a lubricating grease consisting of mineral oil thickened with sodium stearate.  For comparison purposes, the effect of adding the resinous condensation product instead of the reaction product thereof with ethylene oxide is described.ALSO:An additive for lubricating greases (see Group III) is prepared by reacting an alkylene oxide with a resinous condensation product obtained by condensing an alkyl phenol with formaldehyde, or with a polymer of formaldehyde such as paraformaldehyde or trioxymethylene, in the presence of ammonia.  The resinous condensation product is stated to contain the groups -OH and -NH2.  Alkylene oxides mentioned are ethylene, propylene and butylene oxides.  In examples, p-iso-octyl phenol is condensed with trioxymethylene in the presence of ammonia and a mineral oil diluent and the resin obtained is reacted with ethylene oxide.
