Wide-band modulating potentials are superimposed in the grid circuit of a driven wide-band amplifier stage to which a narrow-band driving carrier-frequency amplifier is coupled through a constant impedance network comprising at least two sections. In one embodiment the driving amplifier V1 has an anode circuit L1, C1, sharply tuned to the carrier frequency input and coupled to inductance 2L1. (The numerical part of the references is not a multiplier but merely a distinguishing number.) The first network section comprises the elements L, C, R dimensioned so that #L/C=R. Inductance 2L1 is of such a value that it tunes capacitance C to the carrier frequency. Capacitance 2C1 is included to tune the inductance L to the carrier frequency. A second network section comprises elements 2L, 2C, 2R dimensioned as in the first section and capacitance 3C1 and inductance 3L1 are included to tune inductance 2L and capacitance 2C, respectively, to the carrier frequency. The wide-band modulating source M is included in the shunt arm 2C, 2R, across the input grid circuit of the wide-band driven amplifier V2. The second network section includes an effective resistance R which is presented by the whole network consisting of the elements L1, C1, 2L1, C, L, 2C1, and R connected between earth and the junction of 2C1 and 2L, and which is numerically equal, over the narrow band of the driving stage, to the value of the resistance 2R. A further similar embodiment is described in which the elements of the network are arranged differently and the input capacitance of stage V2 is tuned to the carrier frequency, Fig. 2 (not shown).

Abstract: 387,701. Safety razors. JONES, T. P., 53A, Quartz Street, Hospital Hill, Johannesburg, South Africa. Aug. 10, 1931, No. 22560. [Class 30.] . In a safety razor having one or two pairs of oppositely inclined blades, the individual blades of each pair cutting alternately on forward and reverse strokes, means are provided for adjusting the inclination of the blades. The idle blade operates to stretch the skin ahead of the cutting blade. The razor shown in Fig. 1 has two pairs of blades 16, the carriers 10 .. 13 of which are pivoted at 18 in a rectangular frame 4, pivotally mounted at 5 and locked by a spring-pressed handled pin 7 in a U-shaped frame 3 to enable either pair of blades to be used. The inclination of all the blade carriers is simultaneously adjusted by rotating the milled head of a left-and-right-hand threaded screw 40 engaging guided nuts 43, 44 connected by links 47 with the carriers. The modification shown in Fig. 3 uses one pair of blade carriers adjusted by rotating a nut 55, fixed to the base 54, about a screwed elbow 53 carrying a rubber pad 52 engaging arms 58 on the blade carrier. The nut is locked by a groove-engaging set-screw 57. The bladeclamping carriers 10 .. 13 each comprise a lower plate 14 having a central longitudinal depression 20 engaged by a similar depression 32 on a clamping-plate 15 and projecting through a slot 30 in the blade. The depression 20 is deepened somewhat at its ends to receive internal tongues 31 on the blade which are bent down by the clamping-plate. The blade is clamped flat or bent and is also located on the plate 14 by small projections at the side of the depression 20. To clamp the blade, a lower bar 36, pivoted and longitudinally slidable in end lugs 34 on the clamping-plate 15, is passed through stirrups 23 on the lower plate 14 into an aperture in a square pin 33 projecting from the clamping-plate 15. The clamping-plate can be disengaged by pivotal movement about the end of the bar 36 after it has been freed from the pin 33. Finger notches 38 in the clamping-plate and near the edge of the depression 20 in the lower plate facilitate lifting the clamping-plate and blade respectively. The lower plates 14 have corner lugs 26 which shield the blade corners and form mounts for rods rotatably carrying beads 28 which serve as guards. The aligned handle 1 which screws on or is integral with the frame 3 or elbow 53 is longitudinally split and pressed apart by coil springs 48 located by studs 49. The resilience can be varied by sliding a loose ring 51 into an appropriate groove 50.

Abstract: A liquid binder, such as glue, is applied to wood shavings or chips, the binder being formed into a thin film having a comparatively large area by passing the binder successively over cylinders arranged in contact with one another so that the binder is transferred from one roller to another to form on the final cylinder a film of reduced thickness.  The shavings or chips are conveyed in contact with this film so as to <PICT:0621786/III/1> <PICT:0621786/III/2> coat the individual shavings or chips in a uniform manner.  The thickness of the film may be progressively reduced in passing from one cylinder to the next.  Fig. 1 shows one form of apparatus. The liquid binder 2 is taken up by the roller 3, the excess being kept back by the scraper 4.  A film of binder is passed to roller 5 which is adjustable by the spring 7, and then to the final roller 6.  Chips or shavings are passed down between two such final rollers and then disaggregated by the toothed rollers 9. The process is repeated by passing these coated shavings or chips through a similar set of rollers.  In another form of apparatus, shown in Fig. 2, the shavings or chips are caused to be thrown against the binder film by means of the rotating fluted cylinders 10 and 11 which have a greater peripheral speed than the cylinder 6.ALSO:Wood shavings or chips are coated with a liquid binding substance such as glue in a uniform manner by passing the binder over successive rollers so as to form on the final roller a film of reduced thickness and comparatively large area and then conveying the chips or shavings into contact with the film.

Title: Process for the production of neutral alkyl esters of sulphuric acid
IPC: C07C29/06
Filed: 1920-08-03
Abstract: Dialkyl sulphates are prepared by vacuum distilling alkyl acid esters of sulphuric acid with neutral salts of non-volatile polybasic acids, or with salts of non-volatile acids with more than two replaceable hydrogen atoms of which at least two are replaced by a metal.  The added salt takes up the free sulphuric acid as produced, and thus prevents hydrolysis of the acid ester. In a modification, the formation of free sulphuric acid is avoided by distilling a mixture of an alkyl acid sulphate and the corresponding alkyl sodium sulphate, which latter may have been produced during an alkylation in alkaline solution.  Examples are given in which a mixture of ethyl hydrogen sulphate and anhydrous sodium sulphate, or of ethyl hydrogen sulphate and ethyl sodium sulphate, is subjected to vacuum distillation at a pressure of 10-15 mm. of mercury and a temperature of 90-170 DEG  C.
