Abstract: An incendiary device, a method of remotely initiating a fire, and a method of making an incendiary device for remotely igniting fires are provided. The method of making an incendiary device includes forming a solid incendiary composition from potassium nitrate, sulfur, and a polymer. The solid incendiary composition is extruded into a continuous extrusion and then cut into sections to form individual incendiary devices. The method of making the incendiary device further includes extruding the incendiary composition with a wire or bore formed there through. The incendiary device produces a predetermined flame pattern when an ignition wire extending there through is ignited. The incendiary device can be dispensed from a remote location into an area for starting a fire.

Abstract: An incendiary method and apparatus includes a method of making an incendiary apparatus for remotely igniting fires which includes forming the incendiary apparatus with a composition of potassium nitrate, sulfur, and a polymer and then extruding the incendiary composition into a continuous extrusion and cutting the extrusion into sections to form individual incendiary devices. The method includes extruding the incendiary composition with a wire or bore formed therethrough into a generally cylindrical shape. The method also includes selecting an incendiary apparatus having a predetermined shape for producing a predetermined flame pattern when ignited and having an ignition wire extending therethrough, heating the ignition wire, and dispensing the selected incendiary apparatus having the heated ignition wire from a remote location into an area for starting a fire.

Abstract: A testing voltage of 800 to 5000 volts is applied to a measuring electrode constructed of carbon fiber brushes. This testing voltage is regulated to the desired value by means of a control circuit. Sparkover pulses travel through a filter to an output, with the response level of the testing voltage being regulated accordingly. Thus the test is reliable without highly electrically or mechanically stressing the test object.

Abstract: In a process for the measurement of absolute values by means of a non-linearly working measured value emitter, calibration of the measuring device is achieved by determining, for each of a range of measured values emitted, the corresponding absolute values, by means acting independently of the output signal of the measured value emitter, and storing each of the determined absolute values in a store at addresses defined by the measured value, and during a subsequent measuring process the store is interrogated by means of measured value information whereby the stored absolute values are determined. There is also described an apparatus for carrying out the process.

Abstract: A device for measuring at least one dimension of an object comprises two light channels of which one is intended to receive the object and the other serves as a reference channel. Light from the two channels is conducted to respective photo-electric transducers the outputs of which are connected to a comparison circuit. The relationship between the relative intensities of illumination of the transducers provides a measure of the dimension of the object. In order to improve the response characteristics of the transducers they are connected in parallel with mutually reversed polarity and the difference between the electric currents passed by the two transducers is compensated by negative feedback via a resistor connected to the output of an amplifier at the input of which the said transducers are connected.

Abstract: A method and device for contactless measuring of the thickness of layers, particularly of insulating layers on metallic parts whereby a contactless pneumatic servo-mechanism approaches to and maintains a measuring head at a predetermined distance from the layer and whereby the thickness of the layer is ascertained by a measuring pick-up located in the measuring head.

Abstract: A device for positioning a part comprises a signal generator which, upon movement of said part within the vicinity of a required position of the part, produces a signal value which passes through zero at a point when said part is in said required position, and a servo system responsive to said signal value to transmit movement to said part until said signal value reaches zero. The signal generator may operate to define a predetermined stop position into which a part, for example a machine part or a workpiece, is to be moved, or, in cooperation with an appropriately movable member, it may be used to trace a predetermined pattern of movement so that the part to be moved follows said pattern.
