Title: Improvements in or relating to spinnerets for the production of composite filaments
IPC: D01D5/32
Filed: 1962-10-31
Abstract: 974,118. Spinnerets. W. C. HERAEUS G.m.b.H. Oct. 31, 1962 [Nov. 2, 1961], No. 41198/62. Heading B5B. A spinneret for the production, from two spinning compositions, of composite filaments in the form of fibre components which are inseparably united longitudinally has at least one insert member in the spinneret plate to permit the two spinning compositions to be united only within the outlet apertures of the spinneret plate. As shown in Figs. 1 and 3, a spinneret plate 1 has an annular recess 2 which merges into a conical indentation 3, adjoining which are outlet apertures 4, preferably cylindrical, for the composite filaments. An annular insert member 5, seated in the annular recess 2, has an inner rim 6 resting on a shoulder 7 of the recess 2, and also has an outer rim 8 which has no bearing surface. Insert member 5 has an annular bead 10 with a knife edge 9, bead 10 being seated in conical indentation 3. The bead 10 separates two spinning compositions, one of which is supplied through a gap 11 formed by the spinneret plate 1 and insert member 5 to the outlet aperture 4, and the other of which flows to the outlet aperture through bores 12, preferably cylindrical, in insert member 5. The two spinning compositions are united in the outlet apertures 4 beneath the lowest point of the knife edge 9. In the spinneret of Figs. 4 and 6, separate insert members not connected to one another replace the single annular insert member. The spinneret plate 1 has cylindrical ducts 13 which merge into a cone 14 to which are connected the discharge apertures 15. Each insert member 16 is flattened on one side to co-operate with the spinneret plate 1 to form a gap 17 for the passage of one spinning composition, the remainder of the member being seated on the cone 14. The second spinning composition is supplied through conduits 18 which are drilled at an angle with respect to the axis of the ducts 13 in the spinneret plate. The two spinning compositions are united in the outlet aperture 15 below the lowest point of the insert member 16 merging into the knife edge 19. The spinnerets may be used for wet-spinning or melt-spinning of composite filaments of synthetic materials.

Title: Clearing mechanism for sweeping bowling pins into a pin pit of a bowling alley
IPC: A63D5/08
Filed: 1972-09-07
Abstract: 1404034 Bowling pin sweeper PATENT VERWERTUNGS - UND FINANZIERUNGSGESELLSCHAFT SERANIA AG 7 Sept 1972 [22 Sept 1971] 41583/72 Heading A6D A clearing mechanism for sweeping bowling pins into a pin pit comprises:-a sweeper guided for movement in stationary rails; motor driven means for causing the sweeper to perform a linear reciprocating movement along the guide rails between two end positions; a motor driven crank independent of said motor driven means for pivoting the sweeper about a substantially horizontal axis from a rest position to an operative position where it is capable of performing said reciprocating motion to sweep pins into a pit. As shown (Fig. 3) the sweeper 15 is supported by a trolley 20 guided by rails 19. Crank 36 is connected via links 25, 23, 22 to the trolley, the pivot being affixed to the machine frame. A further crank 7 is connected by chain 10 to hook 16, which is pivoted to the pin-setting carriage 2 (Fig. 1, not shown). The end of the hook is engagable with a bar 26 on the trolley. Operation. The 'rest' position is shown in Fig. 2. On operation of motor 32 crank 7 rotates anticlockwise and carriage 2 descends. Downward movement of hook 16 lowers the trolley so that wheel 30 enters the cut-away portion of the upturned end of the guide 28, the arm 44 thereby being lowered into the operative position. Continued rotation of crank 7 raises the pin setter 2, but due to the new inclination of the chain 10 the hook does not re-engage the bar 26. The motor 32 stops after one revolution of the crank 7. Motor 46 then performs one clockwise revolution to reciprocate the trolley along the straight part of the guides 19. Finally the motor 32 causes the crank 7 to perform one clockwise revolution during which the pin-setter is lowered, the hook re-engages bar 26, and both pin-setter and sweep are again raised to the rest position.

Title: Device for treating the pulp-canals of a tooth
IPC: A61C5/02
Filed: 1975-10-15
Abstract: 1516587 Treating pulp canals and chambers of teeth L DETAILLE 15 Oct 1975 [18 Oct 1974] 42128/75 Heading A5R A device for raising the opened pulp chamber 3 and canals 1 of a tooth with a solution, which is subject to two periodic changes of pressure, one of higher frequency than the other, a feed pipe 19 into a chamber 18 within a housing which is a taper fit with a ring 6 adapted to be mounted in the tooth opening and secured by cement 8. The solution passes from the chamber 18 through apertures 21 into the tooth and leaves via conduits 22 and 24 carrying with it the dissolved matter from the tooth. The solution contains 1.5 to 3.75% chloramine and may be followed by a rinsing liquid, drying fluid and a fluid or paste filler. The solution is supplied from a tank 25 by a peristaltic pump 26 through a three-way valve 28 which alternately provides for sucking of the solution and air, the latter through a side pipe 29. A pressostat 31 which reacts to the solution/air mixture acts on the pump when high and low pressures are obtained to disengage and re-engage the pump to create the low frequency pressure oscillations. A further valve 32 is added upon by an electronic vibratory system 33 to generate the high frequency pressure, oscillations at the rate of 40-160 per minute. Alternatively the valve 32 may be dispensed with and the system 33 acts upon the valve 28. The solution is applied to the tooth at the rate of 50-200 cc/minute. In place of air, oxygen or ozone may be used in the solution. For running or drying the tank 25 is replaced by an appropriate container with the respective liquid or fluid. In a modification, Fig. 4, the solution is fed from tank 25 by a pressurized gas, e.g. air, from a pipe 34 which includes a pressure reducer 36, speed regulators 38, 41 and a valve 39 which is subjected to the output of a pressostat 31 so that low frequency pressure fluctuations are produced in the gas and hence in the solution. A by-pass pipe 43 leads gas to the feed pipe 19 and has a valve to supply the solution with gas, this pipe 43 and the pipe 19 having valves 44, 45 which are subjected to the electronic vibratory system 33 to provide the high frequency pressure fluctuations.

Title: Word recognition
IPC: G06F15/18
Filed: 1973-09-10
Abstract: 1435779 Recognition of sounds THRESHOLD TECHNOLOGY Inc 10 Sept 1973 [21 Sept 1972] 42533/73 Heading G4R Apparatus for recognizing sounds, e.g. spoken words, is trained by a succession of training words prior to receiving a word to be recognized. The apparatus includes a known feature extraction circuit for generating feature signals on corresponding features output for each input word. The feature signals are stored as a function of their time of occurrence in a word. The stored feature signals of the unknown word are compared with stored feature signals of each training word to provide a correlation signal indicative of the degree of match. In the training mode, the input word waveform is filtered by a bank of filters, each providing a signal representing the spectral components in a corresponding frequency band. The signals are rectified, filtered, and logarithmically amplified prior to passing to the feature extraction circuit. For each word the circuit provides, on each of 31 leads, an output bit representing the presence or absence of the corresponding feature at successive sampling instants, e.g. millisecond intervals. The feature signal bits are stored as a function of their time of occurrence (e.g. as in Fig. 3, not shown). The stored feature signals are now normalized with respect to time unless the feature circuit has found that the word is of such short duration that it must be considered to be noise, in which case the store is cleared. The normalized feature signals are stored (e.g. as in Fig. 4, not shown). Normalized signals are similarly derived for each training word. In the recognition mode the apparatus operates in the same manner to enter normalized feature signals derived from the unknown word into a further store. The feature signals from this store are compared with the features of the first training word. When the comparison indicates the presence of the same feature in corresponding time slots the correlation figure S is increased by one, and if the feature is present in only one of the time slots S is reduced by one. S is unchanged if there is no feature in either slot. Correlations figures are generated similarly by comparison of the unknown word feature signals with those of the first training word shifted one time slot forwards S<SP>+1</SP> and one slot backwards S<SP>-1</SP>. The correlation value S=2S<SP>0</SP>+S<SP>+1</SP>+S<SP>-1</SP> is then formed and stored. The presence of S<SP>+1</SP> and S<SP>-1</SP> in S compensates for small time variations of features within the same word spoken by the same speaker. Correlation values S are obtained similarly in respect of each training word, and the largest is selected. Provided that the selected value S exceeds a preset minimum the unknown word is identified with the corresponding training word.
