Abstract: The method entails passing impure gases from an incineration plant such as a destructor, process furnace, crematory furnace or heating boiler, through a burner in an afterburner where through enforced mixture with combustion gas they undergo complete combustion. The combustion gas, depending on the composition of the flue gases, may consist of air or oxygen or either mixed with liquid petroleum gas. 
<??>In the device for implementation of the method the flue gases and the combustion gas are introduced into a burner (10, 44) which blows the gas mixture into a flame bowl (3, 52) where temperatures in the 1500 - 2000 DEG C range can be achieved. In one version of the invention the burner (44) produces a conical basketshaped flame in which the flue gases undergo complete combustion.

Abstract: For the measurement of large currents, d.c. as well as a.c., a so called zero-flux current transformer may be used. It comprises two identically wound toroidal cores (11,12), in which the magnetic flux induced by a main or primary current (I1) is neutralized by a counter-flux induced by a compensation current (I2), which by means of an amplifier circuit (40) is passed through a compensation winding (14) common for both cores (11,12) and having many turns. The compensation current (I2) is adjusted by means of the amplifier (40) to such a value, that the mean flux in the cores (11,12) is zero. The intensity of the compensation current (I2) is measured by the voltage drop across a measuring resistor (15). Any unbalances between the primary and secondary ampere-turns are sensed by a detecting circuit comprising a sensing winding (21,22) wound on each core (11,12) and divided into two subwindings which carries a magnetizing current (I3) from a current source (23) in such a way, that the odd-harmonic components contained in the magnetizing current are outbalanced, whilst the even-harmonic components contained therein are added and conducted to a synchronous rectifier (32) to provide a control signal to the amplifier (40) for the adjusting of the compensation current (I2). 
<??>Hereby is obtained a largely improved signal-to-noise ratio for the signal applied to the synchronous rectifier (32), and the need for a complex and expensive active 2nd-harmonic filter is eliminated.

Abstract: A method of preparation for acetals utilizing saturated or unsaturated aldehydes, in particular, the preparation of dimethylacetals of acetaldehyde, acrolein and methacrolein. The production of the acetal takes place in a liquid phase in the presence of a solid acid catalyst, such as a strongly acidic ion exchange resin or zeolite. The conversion mixture is extracted by means of water and by means of water insoluble organic solvents. There is obtained not only the desired acetals, but in addition also the unconverted initial quantities of the starting materials by a simple method and with very good yields.

Abstract: Synchronisation signals are transmitted in the form of alternating digital words placed at the beginning of the lines of a television signal. Receiving apparatus comprises means (20, 21) for deriving a signal indicative of the presence of each of the digital words and an evaluating circuit (22, 25) which compares the derived signal representing each word with the same signal derived one line earlier and stored in a delay circuit (24) in order to determine whether the correct alternating sequence has been received and to generate a line sync signal if the correct sequence has been received. In a further embodiment adaptive control of the evaluating circuit (23, 25) is provided. Field syncs can also be generated by detecting repetition of one of the words at the end of one field and repetition of the other of the words at the start of the next field.

Abstract: A material particularly used for protecting a lens surface against scratching comprises a solution containing nitrocellulose in solvent the nitrocellulose being present in the solvent in the range 2.5% to 3.8% by weight. When the material is applied to a lens a coating adheres to the lens in which nitrocellulose is the principal constituent. This coating protects the lens against scratching during manufacture and enables traditional manufacturing processes to be applied for identifying and marking the focal centre of the lens blank prior to shaping the periphery of the blank because the coating does not disguise the optical properties of the lens.

Abstract: An improvement to electrical circuit test probes of the type wherein a socket tube having a cylindrical spring loaded plunger therein is mounted in a test fixture. Electrical contact is assured between the socket and the plunger as the plunger moves longitudinally by the plunger having a resiliently flexible wand extending inwardly therefrom at an angular offset to the longitudinal axis of the plunger and the wand terminating in a bulbous contact member. The contact member is disposed within a cylindrical plunger tube and passes through an opening through which the contact member cannot pass. As a result, the wand acts as a flexible resilient finger holding the contact member firmly against the inner wall of the plunger tube as the plunger is moved in and out through its limits of movement.

Abstract: A detector for an alarm system receives a disturbance signal and transmits an alarm signal to a remote station. A group of such detectors can be connected in circuitto operate a common alarm. The detector has means (6,26,33) for suppressing a first disturbance signal so that only a second and subsequent ones trigger the alarm. There are also means (8, 30) whereby a disturbance signal only of a given length can pass to trigger the alarm. With another facility (38, 43) the detector registers whether it is the first or a subsequent one in a group to be disturbed. The detector is largely embodied on an integrated circuit chip and all these facilities are selectable by making or omitting simple pin connections.
