Abstract: 1,028,834. Recording tracks of particles. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 2, 1964 [June 11, 1963], No. 22816/64. Heading G6P. In a device for indicating the distribution of a radio-active emitter over a given surface, a spark is formed at each point where radiation is incident on the indicator. The device consists of a vessel containing a low-pressure gas and a D.C. energized cathode and anode. A radiation particle enters the vessel, passing through the cathode, and causes electron multiplication in the gas. The D.C. voltage is so chosen that no spark is formed at this stage. An external circuit detects the electron pulse at the anode and causes an impulsive negative potential to be applied to the cathode, thus forming a spark at the point of impact of the radiation on the cathode. The metal cathode may be replaced by a scintillator and a photocathode.

Title: Improvements in and relating to signalling systems employing electric oscillations
IPC: H03D9/06
Filed: 1921-08-30
Abstract: 193,882. Taggart, J. Scott-, and Radio Communication Co., Ltd. Aug. 30, 1921. Heterodyne receiving systems; atmospherics and undesired signals, eliminating or limiting; thermionic amplifiers and detectors.-In a wireless receiving system operating on the heterodyne principle, the local oscillations are set in ' operation, or are controlled in magnitude or frequency, by the received signals. The system may be used for eliminating interfering signals which are weaker or stronger than the desired signals, and for reducing interference from atmospherics and damped waves. Fig. 2 shows one circuit arrangement in which the received oscillations after amplification in the valves V1, V2 are applied to the grid of a valve V3. This grid is normally given a negative potential by a potentiometer P4 of such value that only the stronger signals produce any effect in the anode circuit. The stronger signals cause a variation oi voltage across a condenser-shunted resistance R. which voltage is applied to the grid of a valve V4. This valve acts as an amplifier of the oscillations supplied by a local source L3, and is normally inoperative owing to the negative potential applied by a potentiometer P2 to its grid. The stronger signals cause amplified local oscillations to be supplied by a coil L4 to the receiving-circuits, and give audible beats in the telephone T. The weaker signals do not permit the local oscillations to become effective, and are therefore not heard. A two-electrode valve may replace the valve V3, the coil L2, potentiometer P4, and resistance R being in series in its anode-filament circuit. If the connections of the resistance R in the grid circuit of the valve V4 are reversed, signal reception will depress the potential of the grid and by this means strong signals and atmospherics may be reduced or rendered inaudible. Fig. 5 shows an arrangement in which a two-electrode limiter V3 is employed, the voltage across the resistance R being used to vary the resistance of a valve V4 which is connected as a shunt across the oscillatory circuit L10, L4, C10. Oscillations for heterodyning are sustained in this circuit by a valve V5, and the varying resistance of the valve V4, due to the received signals, varies the frequency of these oscillations. Signals are received in a telehpone T in the circuit of a detector valve V8 which has its grid circuit coupled jointly to the local oscillator V5 and to the receiving amplifier V7. Strong interfering signals may thus be arranged to vary the local frequency sufficiently to render the beats inaudible. Other sigals would give different beat notes in accordance with their intensity.

Abstract: 444,541. Centrifugal gas - cleaners. BOOTH, V., BOOTH, W., BOOTH, E., and BOOTH, J., Canal Wharf Works, Canal Road, Congleton, Cheshire. Aug. 16, 1935, No. 23094. [Class 23] The receiving chamber 1 of a cyclone separator communicates by an opening 6 with an expansion chamber 5 which is in communication with the atmosphere through filtering means 11, 12. A cone 2 forms the lower part of the chamber 1 and it is surrounded by an outer cone 4 with an outlet 7 controlled by an apertured damper 8. A baffle tube 16 depends from the cover 15, and an outlet tube 18 is arranged at its upper end to communicate with the atmosphere by lateral ports 19 which can be varied by the adjustment of a top baffle plate 21. The annular space between the tubes 16, 18 communicates with a helical conduit 23 which in the example shown, is connected by a pipe 24 to the intake 25 of a fan 26. The volume of gas passing out by this path is varied by a valve placed in the conduit 23 or the pipe 24. The gas charged with disintegrated material enters the apparatus by the pipe 28 under the pressure of the fan 26, and passes tangentially into the chamber 1. The coarser solids drop to the outlet 7 and the gas rises in the baffle tube 16 to pass to the fan by the helical conduit 23 and to the atmosphere through the tube 18. Part of the gas with fine solid matter suspended in it rises through the expansion chamber 5 and passes to the atmosphere through the filters 11, 12. These are made of wooden frames 14 carrying wire, silk, or other gauze of suitable mesh. A sack may be secured at the discharge opening 7.

Title: Process for the manufacture of quaternary ammonium salts
IPC: C07D233/16
Filed: 1955-08-10
Abstract: Quaternary ammonium compounds are made by treating an amide X-R1-CO-NR2R3 with a tertiary amine Z-NR1R11, where R1 and R11 are alkyl or hydroxyalkyl, R1 is alkylene of 1-7 carbon atoms (which may be interrupted by hetero atoms), R2 and R3 are H or alkyl or substituted alkyl of 5 or less carbon atoms, and Z is the residue <FORM:0814246/IV (b)/1> or is R-CO-Y-A-, where R is a nonaromatic hydrocarbon radical of 8 or more carbon atoms, Y is a hetero-atom and A is alkylene of 2-6 carbon atoms; X is a substituent capable of forming the anion of the quaternary salt, e.g. halogen, but this may be exchanged for other inorganic or organic anions after the quaternation.  The imidazoline starting materials can be made by the method of Specification 793,786.  The amines containing the residue R-CO-Y-A- can be made by acylating a diamine or hydroxyamine with a suitable carboxylic acid (or chloride, ester or anhydride thereof), and if necessary converting the primary or secondary amino group into tertiary by alkylation or hydroxyalkylation (e.g. with ethylene oxide).  Such tertiary amines can be of the formula R-CO-O-A-NR1R11 or R-CO-NH-A-NR1R11, especially <FORM:0814246/IV (b)/2> where k, m and n are 1 or 2 and p is 10-16.  The quaternated products are washing, wetting, dispersing and emulsifying agents, especially for cosmetic or hair-treating preparations.  In examples, chloracetamide is treated with (1) coconut fatty acid ester of N : N-dimethylethanolamine; (2) the imidazoline obtained by heating coconut fatty acid and diethylenetriamine in the presence of boric acid and xylene, and treating the product with ethylene oxide or propylene oxide; (3) N : N-dimethylpropylenediamine acylated with coconut fatty acid; (4) N : N-diethyl-propylenediamine acylated with stearic acid.  The starting material may also be an acylated ethylene or hexamethylene diamine, dimethyl-ethanolamine, dipropyl-ethanolamine or triethanolamine.  Other carboxylic acids that may form the acyl residue are capric, lauric, myristic, palmitic, oleic or linoleic.  Specification 793,786 is referred to.

Abstract: 1,008,760. Hydrodynamic torque converters. ELEKTRO - MECHANIK - G.m.b.H. June 15, 1962 [June 20, 1961], No. 23110/62. Heading F2C. Oil is supplied to the working circuit of a hydrodynamic torque converter upstream of the pump at a radius greater than the minimum radius of the working circuit, and maintains the pressure in the circuit at the point of introduction at a desired value. This results in a lowering of the pressure in the working circuit in the vicinity of the converter axis under stall and near stall conditions. The radial distance of the point of introduction may be varied manually or automatically and the pressure at which the oil is introduced may also be varied. In one embodiment oil is introduced through a pipe 28 and a passage in a rotatable cylinder 32 to an eccentric port 33 opening into the converter working circuit. Rotation of the cylinder 32 by a lever 34 thus varies the distance of the port 33 from the axis of the converter. The pressure in the working circuit in the vicinity of the port 33 is maintained at the pressure at which the oil is supplied, and with the output shaft 22 stationary or rotating slowly the pressure in the vicinity of the converter axis is reduced below atmospheric and air passes through the oil seals 24 to reduce the filling of the converter and hence reduce the torque transmitted. In a modification filling oil is introduced through a tube which is adjustable radially of the converter to vary the point of admission of fluid to the circuit. In other embodiments the point of admission of fluid to the circuit may be fixed, and the oil seals 24 instead of being in the vicinity of the axis of the converter, may be in the vicinity of the point of introduction of fluid to prevent entry of air into the working circuit, thus maintaining a constant filling of the working circuit but still reducing the pressure at stall in the vicinity of the converter axis.
