Title: Improved process for the production of fluorescent monotriazole compounds and the resulting product
Filed: 1955-01-11
Abstract: In the preparation of 2-stilbyl-(naptho-11.21:4.5) -1 : 2 : 3-triazoles by the process of the parent Specification, the handling of 2-aminonaphthalene in the first step is avoided by employing as coupling component a sulphonated derivative of 2-aminonaphthalene, coupling in the 1-position, from which the sulphonic acid group or the radical carrying it is split off at a suitable stage in the dyestuff or triazole formation.  As coupling components from which the sulphonic acid group is split off during coupling may be used 2-aminonaphthalene-1-sulphonic acid or 2-naphthylsulphamic acid, which, owing to their relatively slight coupling power, are advantageously coupled at a higher temperature than is usual (e.g. at 40-60 DEG C.), in the presence of additives which stabilize the diazo compound (e.g. naphthalene-mono- and di-sulphonic acids or tetrahydronaphthalenesulphonic acids).  Alternatively there may be used N-2-naphthylmethylamine - o  - sulphonic acid, from which the sulphomethyl radical is subsequently split off, advantageously by alkaline hydrolysis before the oxidation step, or such 2-aminonaphthalenesulphonic acids, coupling in the 1-position, the sulphonic acid group of which can be split off by mineral acid hydrolysis of either the aminoazo dyestuff or the triazole. Examples describe the use of the three coupling components specified above, the diazo component in each case being 4-aminostilbene-2-sulphonic acid and the o-aminoazo dyestuff being oxidized with sodium hypochlorite to 2-(stilbyl -411) - (naphtho - 11.21:4.5) - 1.2.3 - triazol -211-sulphonic acid.ALSO:In the process of the Parent Specification, the handling of 2-aminonaphthalene is avoided by coupling the diazotized 4-aminostilbene-2-sulphonic acid with a sulphonated derivative of 2-aminonaphthalene, coupling in the 1-position, from which the sulphonic acid group or the radical carrying it is simultaneously or subsequently split off.  As coupling components from which the sulphonic acid group is split off during coupling may be used 2-aminonaphthalene-1-sulphonic acid or 2-naphthylsulphonic acid, which, owing to their relatively slight coupling power, are advantageously coupled at a higher temperature than is usual (e.g. at 40-60 DEG C.), in the presence of additives which stabilize the diazo compound (e.g. naphthalene-mono- and di-sulphonic acids or tetrahydronaphthalenesulphonic acids). Alternatively there may be used N-2-naphthylmethylamine - o  - sulphonic acid, from which the sulphomethyl radical is subsequently split off, advantageously by alkaline hydrolysis, or such 2-aminonaphthalenesulphonic acids, coupling in the 1-position, the sulphonic acid group of which can be split off by mineral acid hydrolysis.  Examples describe the use of the three coupling components specified above.

Title: Improvements in or relating to hydraulic brake systems
IPC: F16D65/22
Filed: 1940-01-15
Abstract: 534,189. Hydraulic brakes. CLEVELAND, F. J. (Bendix Aviation Corporation). Jan. 15, 1940, No. 865. [Class 103 (i)] In a hydraulically actuated wheel brake assembly, in which a fixed cylinder has a pair of pistons pressed apart to apply the brake and each piston is provided with packing means having a forwardly directed lip, each of the pistons and/or its packing is shaped to occupy substantially the whole of the space occupied by the lip. leaving between the fullyretracted pistons a substantially flat circular space communicating at one side through a port 19 with the pressure supply and at the opposite side with a bleeding outlet by means of a port 31. In the form shown in Fig. 2 the packings 32 and 33 with lip portions 34 have their centres filled by thickenings 36 of the packings, the annular space between the lips and projections being utilized to receive a compression spring 35 for forcing the packings against their respective pistons. A number of other forms are described in which the packings are centrally filled by separate metal pieces or by projections from the pistons. As shown in Fig. 2 the upper piston is provided with a non- rotatable plug 22 axially adjustable by being threaded into a flanged collar 23, a projection 25 of the shoe 13 abutting on the plug 22 and a projection 27 on the shoe 14 abutting on a wear plate in the lower piston.

Title: Improvements in or relating to variable-speed transmission gear
IPC: F16H3/72
Filed: 1939-01-11
Abstract: 523,637. Variable-speed gearing. MOSES, R. I. Jan. 11, 1939, No. 958. [Class 80 (ii)] A variable-speed gearing comprises a driving shaft 2 carrying a pinion 6 driving a wheel 4 on a driven shaft 1 through a planet gear 11 on a sleeve 7. The motion of the gear 11 about the axis of the shaft 2 is controlled by an eccentric 12 in a block 13 freely slidable vertically in a member 15 pivoted on a pin 16. The swinging motion of the member 15 is controlled by fluid in a cylinder. When the shaft 1 is stationary fluid freely travels from one side of the piston to the other to allow free movement of the member 15 and pinion 11. The maximum rotation of the shaft 1 is effected by locking the carrier 8 of the pinion. The fluid spaces at the two ends of the cylinders are connected by pipes and a throttle valve actuated by hand or automatically.

Title: Improvements in or relating to pneumatically operated controlling mechanism for electric motors
IPC: B60L15/34
Filed: 1928-01-11
Abstract: 283,526. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.) Jan. 12, 1927, [Convention date]. Locking. - in pneumatically-operated ratchet mechanism for the controllers of electric motors, the solenoidoperated valves, one of which is shc.wn at 1, Fig. 1, are locked during rotation of the ratchet by a notched disc 9 pressing through a bell-crank lever 7 upon a friction clamp 5. At the stationary points of the controller and notched disc a spring 6 draws back the clamping member and thus frees the valve. A pneumatic relay may be interposed between the lever 7 and the clamping member. For locking the valve in one position only and at the same time pressing it firmly on its seat, a roller 20, Fig. 4, actuated by the notched disc as in the other modifications, moves across a cam-surfaced plate 16 spring-seated on the valve-rod 21. Direct pneumatic pressure may be put on the valve-rod for the same object. As shown in Fig. 6, the valve-locking member may be associated with a device 29 for opening a switch 28 in the circuit of the valve solenoid 27, the switch being held open by a winding 28<1> if the motor is taking an excessive current. The driver's master controller 23 is connected to the solenoid circuit in such a manner that the ratchet progression stops at intermediate stages until the master controller is moved a step further.
Patent HK-21794-A (HK)
Title: An adaptive threshold voiced detector
Inventor: THOMSON DAVID LYNN
IPC: G10L25/93
Filed: 1994-03-10
Abstract: Apparatus for detecting a fundamental frequency in speech by statistically analyzing a discriminant variable generated by a discriminant voiced detector (102) so as to determine the presence of the fundamental frequency in a changing speech environment. A statistical calculator (103) is responsive to the discriminant variable to first calculate the average of all of the values of the discriminant variable over the present and past speech frames and then to determine the overall probability that any frame will be unvoiced. In addition, the calculator informs two values, one value represents the statistical average of discriminant values that an unvoiced frame's discriminant variable would have and the other value represents the statistical average of the discriminant values for voice frames. These latter calculations are performed utilizing not only the average discriminant value but also a weight value and a threshold value which are adaptively determined by a threshold calculator (104) from frame to frame. An unvoiced/voiced determinator (105) makes the unvoiced/voiced decision by utilizing the weight and threshold values.

Title: Method and apparatus for the naming of database component files to avoid duplication of files
Inventor: GRAMLICH WAYNE C
IPC: G06F17/30
Filed: 1994-05-24
Abstract: In the method and apparatus of the present invention a file to be added to the database is given a unique name that is dependent upon the contents of the file such that, when the contents of the source file changes, the name of the database component file to be added to the database also changes. Conversely, if two files of the same name have the same information contained therein, the same file name will be generated and the duplication of information in the database is prevented by providing a simple test that checks for the existence of the name of the database file before the generation and addition of the new file to the database. If the file name exists in the database, information is already contained in the database and the file is not generated and added to the database information. Preferably the name of the file is generated by computing a hash value from the contents of the file concatenating the hash value to the name of the source file. Because the source file name is used in conjunction with the hash value to construct the database file name, the hash value does not have to be unique for all files but only for those source files having the same name.

Title: Method and apparatus for measuring the strength of a radio frequency signal
Inventor: MCLAUGHLIN MICHAEL JOSEPH
IPC: H04B7/26
Filed: 1989-12-07
Abstract: A method and apparatus for measuring the strength of a radio frequency (RF) signal subject to Rayleigh fading. The strength of the RF signal is sampled two or more times during a predetermined time interval and the sampled signal strength having the largest magnitude is selected. The selected signal strength is a reasonably accurate measure of the signal strength since the true average strength of a Rayleigh fading signal is close to its peak signal strength. The inventive method and apparatus is particularly well adapted for use in a scanning receiver located in a base station radio (111, 121, 131) of a cellular radiotelephone communications system. The scanning receiver includes an antenna selector (102) for selecting one of a plurality of sector antennas, an RF signal receiver (104) tunable to a plurality of different RF signal frequencies, an analog-to-digital converter (106) for converting RF signal strength samples to a binary data signal and a microprocessor (114) together with peripheral devices (108, 110, 112, 116, 118, 120) for controlling the operation of the antenna selector (102), RF signal receiver (104) and analog-to-digital converter (106).
