Title: Mine conveyor ventilating system - has holes through base channel for air entry and attachment of tube connected to exhaust fan
IPC: E21F5/00
Filed: 1973-03-16
Abstract: The mine conveyor running parallel to the cutting face has the lower strand of its conveyor belt ventilated over its complete length. Gases are extracted by circulation of air, reducing the danger of explosion. The base channel (3) furthest from the cutting face, has holes (4) through it so that air may enter. A flexible tube (5) connected to an exhaust fan (6) is connected to a selected hole. Further air can be admitted under the other parallel channel, by inserting wedges (7) underneath it.

Title: Automatic distortion correction for digital data transmission - which is set to defined condition when disturbance occurs by use of compensator with integrating units and operational amplifier
IPC: H04B3/06
Filed: 1973-04-18
Abstract: The application is to the processing of signals received from a data transmission link, for example PCM signals sent over a power line carrier, in order to compensate for distortion. In an automatic circuit for distortion correction control may be lost due to disturbances. In such an event the disturbance is detected and a preset dc voltage level applied to the compensator in place of the controlled voltage. Automatic control is restored after the disturbance has passed, and stable conditions rapidly re-established as recovery is from a defined starting point. Without the proposed modification the automatic correction may, due to the disturbance, reach a condition fom which recovery time is long. In one circuit arrangement, a dc voltage pulse is applied to an operational amplifier (OP), an integration resistor (Rj) in parallel with a coupling resistor (Rp) with switched output to an integrating capacitor (Cj) and an FET with output to a differential amplifier (A).

Abstract: Packing containers with fold-out pouring spout are used for a great number of beverages, e.g. milk. The pouring spout comprises a number of connected triangular wall panels which are delimited by folding lines. On opening the pouring spout is folded out and the packing container is opened in that an outer end of the pouring spout is removed. To prevent the pouring spout from reverting to its folded-in condition after the opening the folding lines which delimit the material panel of the pouring spout from the upper side of the packing container are arranged so that they run at unequal angles. In this manner the breaking open and the forming of the pouring spout are facilitated.

Abstract: To determine the calorific value of the combustible energy-carrying matter, particularly in gaseous form, flowing in a pipe (1), the combustible matter is burnt in a combustion chamber (110) suitable for measuring a small known fraction (qgas) of the mass flow rate (Qgas) of the matter. The air-fuel ratio (f) applying to the combustion in the chamber (110) is measured by means of a measuring circuit (104'). The mass flow rate of the air (qair) used for the combustion in a pipe (103) is measured by means of a measuring device (106). A computer (160) is used to deduce the calorific value (Pu) of the matter flowing in the pipe (1) from the measurements of the mass flow rate of the air (qair) used for the combustion flowing in the pipe (103) and from the measurement of the air-fuel ratio (f). In a variant, the air-fuel ratio (f) may be adjusted using a control circuit (104). <IMAGE>

Abstract: A device to be used in phonometric measurements on telephone equipment, simulating a human ear, has a generally disk-shaped body with an annular ridge encompassing a frustoconical central recess serving as a wide-open entrance cavity. The body has several internal cavities communicating with the recess through restricted channels, namely a pair of major cavities resonant at low audio frequencies, an intermediate cavity resonant in the middle audio range, and a minor cavity resonant at high audio frequencies, the last-mentioned cavity having the shape of a narrow cylinder extending generally along the body axis. A microphone, connected to a measuring circuit, rises from the bottom of the recess to substantially the top level of the surrounding ridge to pick up incoming sounds at that level.

Abstract: In a television transmission system for digital picture signals each picture is split up into sub-pictures of NxN pixels for the purpose of reducing the bit rate. Each sub-picture is subjected to a two-dimensional discrete cosine transform (DCT) for determining basic picture weighting factors (coefficients) which are converted by means of adaptive coding into code words of variable length. This two-dimensional DCT is realised by multiplying the pixels of each row of the sub-picture by the NxN DCT matrix (one-dimensional transform). Consequently, an NxN array of product elements is obtained. The transposed version thereof is once more multiplied by the NxN DCT matrix. Such a one-dimensional transform comprises three main steps. In a first main step the pixels of a row are converted in a first iteration step into N/2 sum elements u1,i and N/2 difference elements v1,i. In a subsequent iteration step the N/2 sum elements u1,i are converted into N/4 further sum elements u2,i and N/4 further difference elements v2,i. This process is repeated until only two sum elements are left. The difference elements obtained in each step are used to determine a plurality of auxiliary sum elements in still further iteration steps. The remaining two sum elements, the difference elements and the auxiliary sum elements are each multiplied in the second main step by an associated linear combination of elements of the DCT matrix. Of the sub-products thus obtained selected one's of those products are added together or are subtracted from each other in the third main step so that the desired product elements are obtained.

Abstract: The abovementioned compounds are prepared by reacting trialkyl phosphites with phosphorus trichloride and/or monoalkyl esters of dichlorophosphinous acid at -20 to +100 DEG C followed by immediately reacting the product with alkylmagnesium chloride or alkylmagnesium bromide at -60 to +50 DEG C, followed by removing the desired compounds from the distillate of the volatile compound. This allows dialkyl esters of alkylphosphonous acids and monoalkyl esters of dialkylphosphinous acids to be obtained without complicated and costly purification of intermediates. The phosphorus-containing esters obtained, in turn, are valuable intermediates, for example for the preparation of flameproofing agents and crop protection agents.
