Abstract: 144,717. Kolb & Sorgel. Sept. 20, 1917, [Convention date]. Studding-chucks.-In a hvdraulic machine-driven tool for inserting studs, the fluid in the lower cylindrical part of the casing a is compressed by the action of the stud on a pressure plate e of a piston d packed by a spring - retained leather ring f. The upper portion of the tool has a rotatable piston r having a bolt q adapted to slide in an inclined slot in the casing. This piston is integral with the part p having dogs which engage similar dogs on the casing to drive in either direction. On reversing the tool, the piston r is lowered by the bolt q sliding in its groove and the valve k being thereby opened fluid flows into the upper chambers and relieves the pressure. When the plate e leaves the stud the piston d is returned by its spring and the displaced fluid flows back into the lower chamber.

Abstract: 594,040. Radio receiving circuits. PERCIVAL, W. S.June 23. 1945, No. 16052. [Class 40 (v)] In a receiver for amplitude modulated carrier waves having a discriminator for effecting automatic frequency control of the receiver, means are provided whereby an output of said discriminator due to phase modulation of a received carrier wave is arranged to reduce the gain of the receiver when the carrier wave is phase modulated to a predetermined degree. As shown in a superheterodyne receiver, a coil 6 in the output of an I.F. amplifier 5 is coupled to coil 7, detectoramplifier 8 and low-frequency stages not shown, and also to a coil 9 which with elements 10, 11, 12 and 13 comprises a frequency discriminator of the phase shift type. A frequency control voltage is taken across resistances 11, 12 and after smoothing at 14, 15 is fed to the grid of amplifier 5 to alter the current through a transformer winding 16 in the cathode lead. By altering the saturation of the transformer core the inductance of winding 17 is altered and similarly the inductance of coils18, 3, thus altering the frequency of local oscillator 2, to restore correct tuning. Audiofrequency potential due to phase modulation resulting from interference are fed from the discriminator to an amplifier 20 and full-wave rectifier 22, the output from which is fed through a short-time constant circuit 23, 24 as bias to the R.F. amplifier 1, to reduce the gain on the occurrence of interference. A switch 25 is provided to suspend the action of valve 20 during tuning. This switch may be actuated automatically by the act of tuning. Alternatively, the A.F.G. voltage from network 14, 15 may be fed so as to block valve 20 when the set is off tune. Specification 504,229 is referred. to.

Title: An improved process for transforming ammonia into a salt for use as a fertilizer
IPC: C05C3/00
Filed: 1920-07-14
Abstract: The cooling of the concentrated ammonium chloride liquors of the ammonia-soda process for the separation of ammonium chloride, as described in Specification 144,659, is effected by placing the hot concentrated liquor after the separation of the sodium chloride, into a vacuum apparatus so that the resulting evaporation effects the required cooling.  The cooling and evaporation may be increased by allowing a small quantity of air to enter the liquid so as to cause agitation.  The evaporation may be increased by supplying a quantity of heat during the vacuum treatment, but the total evaporation must not be so great as to cause the separated ammonium chloride to be contaminated with sodium chloride.  The hot concentrated liquor to be treated is the mother-liquor obtained after the separation of the sodium bicarbonate and subsequent concentration first at for example 60-80 DEG  C. and then at 100 DEG  C. until the sodium chloride that precipitates shows an admixture of ammonium chloride.ALSO:Sodium chloride is recovered from the mother-liquor obtained in the ammonia-soda process, by subsequent evaporation first at for example 60-80 DEG  C. and then at 100 DEG  C. until the sodium chloride that separates is contaminated with ammonium chloride.

Abstract: 1302466 Digital data storage; AC plasma matrix SPERRY RAND CORP 21 May 1971 [25 May 1970] 16195/71 Heading G4C  An information storage system, e.g. for digital data symbols or graphical data, comprises a matrix of A.C. plasma cells. Prior art.-In an A.C. plasma cell data can be stored by the presence or absence of gas ionization discharges across the cell. Initially all the cells are off and an A.C. sustaining potential less than the potential for ionization, is applied. To write in a cell, a write pulse is applied during part of the sustaining potential cycle which in combination with the sustaining signal switches the cell on, i.e. ionizes the gas. Ions and electrons flow to the cell plates and extinguish the discharge but during the next part of the sustaining cycle the gas ionizes again. This occurs at great frequency and, to an observer, the cell appears to be on continuously. To read out, the sustaining signal is briefly removed and then selectively reapplied to the desired cells for read out. In the present system the sustaining signal is not removed. Apparatus.-This comprises the plates 11, 12, 13 of glass or other dielectric material, plate 11 having a matrix of apertures 14 forming cells and all three being held together with a gas tight seal around their periphery. An X selection matrix 18 is connected through transformers 28 1-4  to electrodes 16 1 -16 4  attached to plate 12 and a Y selection matrix 22 is connected through transformers 21 1 -21 4  to electrodes 19 1 -19 4  attached to plate 13. A sustaining level signal V s  sin wt passes through the cells from A.C. source 23 and current detectors 28 1 -28 4  are provided. It is assumed that all of the cells A to P are on and interrogate signals go to the X and Y matrices from a computer or an operator, the signal going half to the X and half to the Y line. The cells are scanned in turn, e.g. row 19, column 16, are energized, then 19 1  and 16 2  &c. row by row. The net interrogation signal is equal in frequency but twice the amplitude and anti-phase (Figs. 2a, 2b, not shown) which gives a resultant signal of - V s  sin wt in the selected cell and thus the cell functions as before. At the half selected cells the signals cancel out and the non-selected cells continue as before. Thus only the selected cell gives a current output. A photo-cell could also be used to detect the state of a cell. Other features.-In place of individual apertures 14 there can be one large aperture holding a number of cells. In a modification (Figs. 3a to 3c, not shown) the interrogation signal is of the form V s  (sin 2 wt - sin wt). Readout may be performed without coincident addressing by applying the interrogating and sustaining signal to a single row or column of cells. The cells receiving the interrogating signal would provide current and light output pulses at double the frequency of the sustaining signal.

Title: Improvements in drying or eliminating water vapours and nitric or nitrous acid vapours from gases derived from oxidized ammonia
IPC: C01B21/26
Filed: 1921-06-13
Abstract: Water is removed from the gases produced by the oxidation of ammonia, to enable them to be condensed without injury to the refrigerating apparatus, by spraying with liquid oxides in packed towers of known type.  Preferably, the gases are first washed with nitric acid of less than 68 per cent strength to secure partial dehydration.  Using gases containing from 1 to 10 per cent of nitrogen oxides and liquid nitrogen oxides, both at 15 DEG  C, and with a preliminary washing with nitric acid of 15 to 50 per cent strength, the issuing gases are cooled to 0.2 to 0.20 DEG  C. owing to the loss of latent heat of the evaporated nitrogen oxides.  The gases being practically free from water and nitrous and nitric acid vapours at this temperature are then liquefied by cooling for instance to 100 DEG  C. in a refrigerating apparatus such as is used for condensing nitrogen oxides obtained by the oxidation of nitrogen.  A portion of the liquid nitrogen oxides so obtained is used for treating further quantities of nitrous gases.

A mechanism for setting and restoring riders 10 of a tabulator for typewriters and like machines having a slidable platen carriage, .comprises on the carriage a support rail 6 for the riders 10 pivoted with the support on a common axis 11 so that by the actuation of a single member 12 into any of four positions the riders 10 can be set individually, can be restored individually, restored simultaneously or remain in a rest position. In Fig. 3 the member 12 and support 6 are shown in the latter position indicated by I and wherein the riders 10 travel freely between two centrally placed fixed stops 13, 14 and clear of a tabulating-keyoperated stop 5 also positioned in the centre of the machine. To set individual riders the carriage is slidably moved until ,the desired tabulating position is central in respect to the machine and the member 12 is moved against spring pressure 9 into position II, see Fig. 4, whereon the stop 13 engages and anticlockwisely displaces the selected rider 10. The member 12 is returned to position I so that the set riders are in line with the stop 5. Restoring the set keys individually is effected by pivoting the member 12 into position III whereupon the fixed stop 14 restores the riders 10 and to restore all set stops simultaneously the member 12 is moved to position IV so that the riders are all restored to normal by a continuous bar 16 extending the length of the support 6. The rider opposite the stop 14 will however be moved clockwise a greater amount but when the support 6 is brought back to position I this. rider will be corrected by the stop B. Specification 634,817 is referred to.
