Title: Method of and apparatus for verifying voice signals
IPC: G06V30/194
Filed: 1980-05-15
Abstract: The characteristic values are obtained from the signal to be verified, e.g. in the case of a voice signal the total energy in the individual frequency spectrum ranges, and these characteristic values are quantified. The frequency with which the individual partial ranges of the quantified characteristic values occur is found during a sampling phase, and these frequencies are stored. In the test phase, the signal is analyzed in the same way and the stored frequencies of the partial ranges into which the characteristic values of the signal to be verified have fallen are multiplied and compared with a threshold. In an arrangement for implementing the method, there is a characteristic store with a store address for a multi-digit binary number for each partial range of each characteristic. This store is addressed by a counter, the positions of which are allocated to the individual characteristics or spectrum ranges of the voice signal, and by the numbers of the partial ranges of the characteristics found during the analysis into which the characteristic values of the signal to be analyzed have fallen. In the sampling phase the content of each addressed store address is raised by 1 and in the test phase the frequencies obtained in the store addresses addressed are multiplied together. When a voice signal is processed for verification of the speaker, with the stepwise formation of the long-term spectrum, the intermediate values are compared with a range limit of a partial range read out from a range limit store and increased by 1 on exceeding a number allocated to this characteristic in an intermediate store. In this manner, it is possible at the end of the voice signal, immediately and without any further processing steps to obtain the quantified characteristics in the form of the numbers of the partial ranges which can then be used to increase the frequencies in the characteristic store. A summation over all spectrum values is made to standardize the incoming voice signals. Subsequently, to all spectrum values is added a given fraction of their value, performed in the simplest manner by position shifting, until the sum of all spectrum values exceeds a predetermined constant. Thus the determination of the quantified characteristics or the partial range sums is immediately effective. The multiplication of the frequencies may be replaced by the addition of the logarithmic frequencies.

Title: Refinement of sulfonated hydrocarbons
IPC: C07C303/32
Filed: 1980-05-20
Abstract: In a process for the preparation of petroleum sulfonates by sulfonation of a hydrocarbon feedstock with sulfur trioxide, product petroleum sulfonates are separated from unreacted hydrocarbon by a two stage separation process in which the crude product is first mixed with water. A first quantity of unreacted hydrocarbon is then separated to provide an aqueous sulfonate product still containing 5-15 volume % of unreacted hydrocarbon. This is then neutralized and the remaining unreacted hydrocarbon separated from the neutralized product.

Title: Electro-precipitator discharge electrode
IPC: B03C3/41
Filed: 1980-10-08
Abstract: To cheapen the construction and avoid alignment problems of its component parts, a mast discharge electrode, as used in an electro- precipitator, comprises a tube (11) having holes (15) punched transversely therethrough, cross members (12) secured in the holes, e.g. frictionally as by knurling at 16, and at least two wires (13) extending parallel to the tube and passing through holes (20) in the cross members, the wires (13) being secured in the holes also by friction, as by crimping the cross members.

Title: A thermal imaging system
IPC: H01L27/14
Filed: 1981-03-11
Abstract: A thermal imaging system including a biassed elongate detector element (3) of photoconductive material, over which an image of a thermal scene is scanned at a velocity that is matched to the ambipolar drift velocity of photocarriers generated in the element (3). In order to improve responsivity and detectivity the length of the detector element (3) or the magnitudes of bias and scan velocity, are selected so that the time taken to scan the detector element (3) from one end (5) to a read-out region (9) of the detector element (3) is greater than the lifetime of the photocarriers generated in the element (3). In order to avoid loss of resolution by photocarrier diffusion the photocarrier lifetime of the detector material is of necessity of relatively low value. In the example described the detector is of cadmium mercury telluride material sensitive to infra-red radiation in the 8 to 14  mu m band and has a characteristic photocarrier lifetime of around 2  mu s. The system may include several detector elements (3) arranged in parallel. <IMAGE>

Title: Canine biscuit containing discrete meat and/or meat by-product particles and method for making same
Inventor: GELLMAN GARY
IPC: A23K1/00
Filed: 1983-01-21
Abstract: A dry hard or soft canine biscuit having visually apparent, discrete meat and/or meat by-product particles distributed substantially uniformly throughout the biscuit is obtained by blending the non-fat solids portion of a canine biscuit dough with the particles which are substantially inert with respect of the dog biscuit dough, mixing the dry-blended mixture with water and with the fat portion of the pet biscuit dough to form a dough, forming the dough into pieces, and baking and drying the formed pieces to obtain a microbiologically stable product which can be packaged without a barrier material. Meat and/or meat by-product particle inertness is made possible by using particles having: 1) a moisture content of 35% by weight or less and, 2) a water activity which is less than the water activity of said biscuit dough.

Title: Emergency braking mechanism for rail vehicles
Inventor: PISTOR ULRICH
IPC: B61H7/04
Filed: 1983-05-16
Abstract: The mechanism has a plurality of braking shoes (13, 14) which are lowered onto the rails (4) in emergency braking conditions and are linked with the entire vehicle in such a way that approximately full axle load of the vehicle comes to rest on shoes (13, 14) to generate the braking force. In such braking, the entire vehicle runs onto the braking shoes (e.g. 14) resting on the rails (4) in front of the vehicle wheels (2) in the travel direction, the braking shoes (13, 14) having a run-on surface (23) and a braking surface (24), the shoes being mounted on a frame with bars (10) and cross ties (12) which is caused to fall under its own dead weight. The frame is released to fall down by disengaging a latch (18) by means of a rod, or a cable (21). Cable (21) could be operated or substituted by a withdrawable safety mechanism, such as a pin. <IMAGE>

Title: Auxiliary planetary gearbox
Inventor: ANDERSSON SVEN
IPC: F16H3/78
Filed: 1983-06-03
Abstract: A range gearbox of planetary type, designed to be attached to a further vehicle gearbox, a so-called base gearbox has an annulus or gear ring (13) non-rotatably joined to a shift sleeve (14), by means of which the annulus can be locked either to a coupling ring (20) securely joined to the rear housing end wall (4) of the base gearbox, or to a coupling ring (16) which is non-rotatably mounted on the input shaft (5) of the range gearbox. The shift sleeve serves as an annulus carrier and displaces the annulus axially during the shift movement. The range gearbox housing 3 does not take the torque reaction from the annulus and so may be made thinner than if it did take the torque reaction, or may be made of aluminium.

Title: Improvements in or relating to cistern overflow devices
Inventor: FARKAS ISTVAN
IPC: E03D1/00
Filed: 1983-09-13
Abstract: In a siphon-discharge w.c. cistern 1 a bypass pipe 5 of small cross-section is connected across the arms 3 and 6 of the siphon tube to act as a cistern overflow. The ends of the pipe 5 are secured to the pipes 3 and 6 by flanges 7 in an airtight manner. Because the pipe 5 is of small cross-section it will not interfere with the normal flushing operation of the cistern. However, if the water level in the cistern 1 rises above the normal level 2 water will be able to overflow down the outlet arm 6 of the siphon tube by passing from the bell 9 through the bypass pipe 5. <IMAGE>
