Title: Improvements in or relating to hydrocarbon halogenation
IPC: C07C17/10
Filed: 1958-03-27
Abstract: In the thermal gas-phase chlorination of methane, the gaseous reaction product is condensed to give a liquid containing chlorinated methanes and saturated and unsaturated chlorinated higher aliphatic hydrocarbons (produced by molecular fragmentation of the methane and re-combination of the fragments), elemental chlorine is dissolved in the liquid reaction product in amount in excess of that required to react with the unsaturated components of the mixture, the mixture is passed to a reaction zone and exposed to actinic light, while maintaining the mixture in the liquid phase, thereby selectively chlorinating the chlorinated higher hydrocarbons while effecting substantially no further chlorination of the chlorinated methanes, and the mixture is withdrawn from the reaction zone and the components separated by distillation.  Methylene chloride and chloroform are mentioned as the principal reaction products.

Abstract: 372,056. Vehicle ventilators. ELLIS, R. E., 70, Chancery Lane, London.- (Kuckuck, H. ; 17, Pieperstrasse, Bremen, Germany.) April 1, 1931, Nos. 9891 and 24764. [Class 137.] A ventilator, intended more particularly for vehicles, comprises an apertured base 1 and a cover-plate 7 adapted to be secured to the roof or wall of an enclosure, forming a flat-shaped extraction passage open at one or both ends, the edge of the cover-plate at an open end being bent up to extend above the roof of the passage and a deflecting plate secured upon the base either perpendicular thereto or partially bent outwards at its free edge away from the extraction passage. In the form shown in Fig. 2, the extraction passage is open at each end and the upper part of each deflecting plate 8 is curved slightly outwards and the plate as a whole is given a slightly concave form end to end. The space between the deflecting plate and the open end of the passage is preferably subdivided by one or more blades or strips 10 arched over the base and curved in approximately the same manner as the plate 8. The structure is strengthened by bracing pins connecting the plate 8 and blades 10 with the upturned edge of the cover. A transverse groove 13 in the cover adjacent the upturned edge adds rigidity and drains off rainwater. A downwardly curved rain shield 14 may be provided beneath the edge of the cover. In a modification, Fig. 5, each deflecting plate is substantially flat and straight from end to end but the free edge is bent outwardly as at 16. The blades 10 are dished inwardly from their outer to their inner edges. In a further modification, Fig. 7, the extraction passage is open at one end only and the blades 10 are omitted. One or more depending fins 21 are attached to the rain shield 14 to subdivide the air stream.

Title: Improvements in and connected with the coating or covering of shoe and boot heels
IPC: A43B21/00
Filed: 1934-04-03
Abstract: 435,866. Ornamenting. PEARSON, L. R., 1, East Avenue, Leicester. April 3, 1934, No. 9945. [Class 93] [See also Groups VII and VIII] The surface of a shoe heel blank is coated with an adhesive and, while the adhesive is still tacky, subdivided fibrous material, such as textile material in the form of short staple disintegrated wool or cotton flock or disintegrated leather, is sprayed on under pressure in sufficient quantity to conceal the surface. An imitation suede effect may be produced by spraying dyed fibrous material on to cellulosic adhesive applied to the blank. If desired, a proofing solution may be first applied to render it non-absorbent to water and adhesive, and the surface may then be dyed or lacquered. After the spraying, the surface is compacted by a light smoothing pressure and loose material is brushed off. Coatings of differently dyed materials may be applied to the surface through stencils if desired. Specifications 19981/12, [Class 93], and 366,754, [Group VIII], are referred to.

Title: On-the-fly multibyte error correction
Inventor: PATEL ARVIND MOTIBHAI
IPC: G06F/
Filed: 1994-12-08
Abstract: In the multibyte error correcting system, up to t errors are correctable by processing 2t syndrome bytes. Syndrome bytes are converted into t+1 coefficients of the error locator polynomial by predetermined product operations and exclusive-OR operations involving selected syndrome bytes to produce cofactors that correspond to the desired coefficients when less then t errors occurred in the codeword. The cofactors are combined to produce coefficients when t errors occur and the correct set of coefficients are selected in accordance with the number of errors that are detected. Up to t erroneous bytes in one codeword and corrected during its transfer from the system while the next codeword is entered in the system, so that correction is on-the-fly.

Title: Grip gear with speed-limit device arranged on cabin for elevators
Inventor: PEARSON DAVID B
IPC: B66B5/04
Filed: 1991-09-13
Abstract: A safety apparatus includes a safety device and a centrifugal force speed governor for preventing overspeed conditions of an elevator car in both the downward direction and the upward direction. A bracket attached to the elevator car slidably retains a shaft at right angle to a guide rail attached to an elevator shaft wall. A U-shaped frame is attached to an end of the shaft and rotatably carries a running wheel. A compression spring extends over the shaft between the bracket and the frame to bias the running wheel against the web of the guide rail. On each side of the running wheel, a pair of release levers are rotatably supported to rotate during travel of the car in normal operation. In response to an overspeed condition, the release levers pivot into engagement with a pair of stationary ratchet wheels which are connected with a pair of actuating levers. The ratchet wheels are rotated by the running wheel which movement rotates the actuating levers. The actuating levers each move a release arm and one of the levers is connected to an actuating rod, which in turn is in connected to a release arm of another safety device on the car. The release arms extend into a wedge box of the safety device to actuate wedge-shaped jaws to engage the guide rail. For resetting the safety apparatus, the elevator car is restarted after a safety stop in the opposite direction of travel.

Filed: 1992-01-08
Abstract: PURPOSE:To prevent the unwanted consumption of an internal battery by turning on a switching means only in the case of detecting the voltage if the internal battery and connecting a pull down resistor. CONSTITUTION:When the control signal C of an H signal is supplied by external operation in the case of demanding for detecting the voltage of the internal battery 6, the switching means 10 is turned on and the pull down resistor 7 is connected to a connection point between the battery 6 and a current limitting resistor R connecting with a back flow preventing diode D. Then, when the battery 6 is loaded actually, the voltage V of the battery is detected by a comparator 8, and when not loaded, the voltage V is detected without erroneous decision since the voltage of the comparison input terminal (-) of the comparator 8 is fixed to an 'L'. On the other hand, when the voltage detection of the battery 6 is not demanded while operating normally, the means 10 is turned off and the resistor 7 is separated from the battery 6 and the unwanted consumption of the internal battery is prevented and the battery life is lengthened.

Filed: 1980-01-11
Abstract: PURPOSE: To make linear the output voltage to the input voltage, by applying an input to the 1st transistor and forming a negative feedback circuit with the 2nd and 3rd transistors to this transistor.  
     CONSTITUTION: When a signal is fed to the base of a transistor TRQ 11 , an output signal is picked up from the collector of TRQ 13 . The relation between currents i 11  and i 12  by the constant current sources I 11  and I 12  is i 12 ≈1/2I 11 , and since TRs Q 12  and Q 13  form a negative feedback circuit, the voltage at the connecting point A between the base of TRQ 12  and the emitter of TRQ 13  is almost equal to the input voltage. Thus, the voltage change in the connecting point A is almost equal to the change in the input voltage, and the current flowing to a resistor R 11  is depending on the voltage at the point A. Thus, linearity to the input voltage is kept. Since the current flowing to the resistor R 11  is the emitter current of TRQ 13 , the output voltage across the resistor R 12  is also linear.
