Title: System for translating a low level signal in the presence of noise
IPC: H03F1/20
Filed: 1955-05-26
Abstract: 780,774. Television. BENDIX AVIATION CORPORATION. May 26, 1955 [June 2, 1954], No. 15276/55. Drawings to Specification. Class 40 (3). [Also in Group XL (c)] A local-viewing television system employing a camera tube connected to supply signals to a cathode-ray tube via amplifying circuits is characterized in that each and every element or group of elements in the electric circuits which might be shock-excited by a transient to oscillate within the pass-band of the system is provided with damping means to an extent that each said element or group of elements is at least critically damped. The invention is described as applied to a system for intensifying X- ray images at a low light level and is effective to reduce the noise level produced on the cathode-ray tube screen to a figure close to that predicted from classical noise theory. The amplifier circuit comprises three cascadecoupled distributed amplifiers (see Group XL (c)), and in carrying out the invention, damping resistors are inserted in all leads where an oscillatory condition could exist. This is done, not only in the video channel itself, but in auxiliary circuits such as those concerned with power supply and the introduction of blanking and shading signals. In addition, the lines between the amplifier sections and the camera and cathode-ray tubes are damped. Reference is made to the need for damping the dynode circuits where the camera comprises an image orthicon. Preferably the signals are limited in frequency at the input to the pass-band of the system.

Title: Improvements in or relating to moulding compositions and the coating of sand with a phenol-formaldehyde resin
Inventor: PARKES ERIC
IPC: B22C1/22
Filed: 1962-04-24
Abstract: Discrete storage-stable particles of sand individually coated with a phenol-formaldehyde resin are obtained by mixing the sand with an aqueous alkaline solution obtained by condensing a molar excess of phenol with formaldehyde under acid conditions and then adding excess alkali.  Moulding compositions may be obtained by incorporating a curing agent, e.g. e.g. hexamethylenetetramino, and after mixing the sand and resin excess alkali may be neutralized with a mineral or organic acid or an acid oxide.  In a preferred embodiment resin and sand at 350 DEG  F. are milled for 4 minutes, acid is then added to neutralize excess alkali followed by a curing agent and a mould lubricant, e.g. a synthetic amide wax, with further milling first to distribute uniformly the curing agent and lubricant and then to break the mix down to free flowing particles.  The product may be used in the shell moulding process.

Abstract: 1431816 Moisture content measuring apparatus MANNESMANN AG 30 March 1973 [30 March 1972] 15583/73 Heading G1A A calibration curve for a radio metrically operating moisture measuring installation for materials is produced by filling a container, having a volume at least equal to the maximum volume to be measured, with the material, totally wetting the material with water, allowing the water to drain  off, with a radio metric probe measuring instrument switched on, until a stable reading is obtained, emptying the container and spreading out the material, gravimetrically measuring the moisture content of a sample of the spread out material, returning the material to the container after a sample has been taken, repeating, at time intervals, the measuring of the moisture content by the radio metric and gravimetric methods until the material is dry, correlating the measurements obtained to form an actual value curve, and transforming this curve into a calibration curve. The radio metric probe may consist of a source of neutrons e.g. <SP>241</SP> Americium-Beryllium, and a scintillometer. In order to be able to calibrate other instruments operating under like conditions, use is made of a moisture phantom with which different measured values of the calibration curve can be simulated. To this end, adjustable cadmium sheets which enclose the probe, are introduced as neutron absorbers for producing different measured values.  The method can also be carried out in the converse manner by starting off with dry material to establish the first measured value, and subsequently increasing the moisture content of the material.
