Title: Bus travel information system for the blind and vision-impaired
Inventor: YOUSAFZAI RABNAWAZ
IPC: H04M1/72481
Filed: 2009-06-08
Abstract: A Wise Personal Digital Assistant (WPDA) makes it easier for blind and vision-impaired passengers to obtain information about bus timings, locations and destinations. The technology passes real-time information from a talking bus stop to a handheld WPDA which also uses its in-built GPS to inform the user of his/her location, producing aural, spoken messages as its output. The WPDA communicates with the talking bus stop when it is within its vicinity and uses Orthogonal Frequency Division Multiplexing operating around the 5 GHz frequency. The WPDA is Bluetooth (RTM) and WiFi (RTM) enabled and is user-friendly due to its large tactile keys. It also has capacity for additional memory storage and auxiliary devices such as headphones. Aside from its stated purpose, the WPDA also provides useful additional features, such as telephone, talking books and radio. Consequently, the WPDA eliminates the need for carrying other items such as phones on person.

Title: Dynamic random access memory with shadow writes.
Inventor: BAINS KULJIT S
IPC: G06F13/16
Filed: 2009-12-16
Abstract: Disclosed are methods and apparatus for accessing dynamic random access memory (DRAM). The method has the steps of issuing a write column address strobe (CAS) to the DRAM to latch a valid write CAS address for accessing the DRAM. Next the method asserts a set of data values to be stored in a first set of DRAM locations corresponding to the write CAS address. After asserting the write CAS and prior to asserting the complete set of write data values, the method issues a read CAS to the DRAM to indicate a valid read CAS address. Finally, the method receives a set of read data values from a second set of DRAM locations corresponding to read CAS address after asserting the complete set of write data values. The first and second sets of CAS addresses may be in different bank groups. The issuing of the read CAS may occur at least 3 cycles after issuing the write CAS and occur 1 cycle before to asserting the last write data value.

Filed: 1975-04-24
Abstract: 1508981 Cooling brakes; multi-disc brakes GIRLING Ltd 24 April 1975 [7 March 1974] 10159/74 Heading F2E A brake comprises an assembly of friction pairs carried by alternating rotor and stator discs 8, 9 respectively constrained for axial movement relative to coaxial tubes 6, 12 a coolant liquid (e.g. water) being circulated around the outside of the outer tube 12 and inside the inner tube 6, while a gas (e.g. carbon dioxide gas) for protecting the friction pairs is circulated between the tubes 6, 12 and over the discs 8, 9. The fluid 'protects' by inhibiting or reducing deterioration of the friction surfaces of the discs 8, 9 and it may be used with a catalyst. The illustrated embodiment shows a brake for a rail vehicle with a rotatable axle 1 to to which is secured a sleeve 12 constituting the outer tube, the inner tube being constituted by a stationary hub 6. Three angularly spaced hydraulic actuators 15 act via a thrust member 14 to apply axial pressure to the discs 8, 9 to apply the brake. The axial thickness of the discs 8, 9 which are made of carbon fibre decreases progressively from the actuated end towards the other end. To eliminate or reduce wear of the discs 8, 9 caused by oxidation thereof the protective non- oxidizing gas such as carbon dioxide is circulated over the discs 8, 9 within a sealed chamber 16 by means of an impeller 17 rotating with the axle 1. It is envisaged that the system may originally be filled with air of which the oxygen constituent is rapidly converted to oxides of carbon-the pressure of oxygen initially may aid bedding-in of the discs. The cooling water enters the hub through an inlet port 19 and flows along inside the hub into a chamber 20 and thence through passages 22, 23 into a tube 24 by which it is led to an outlet port 25. The ports 19, 25 are preferably connected to an external pump and the circuit may include a radiator or a tank forming a heat sink. In a further embodiment for mounting on a motor or gear-box shaft the outer tube is stationary and the inner tube rotates, the actuators being mounted outside the outer tube. It is envisaged that the disc stack could be clamped by actuators at both ends or by intermediate actuators. The stator and rotor members could be broken up into pads separately supported for axial movement.

Abstract: 1,006,492. Cooling systems for electric generators. SIEMENS-SCHUCKERTWERKE A.G. March 14, 1963 [March 15, 1962], No. 10241/63. Heading F4U. A closed, liquid, pressurized cooling circuit for a machine such as an electric power generator includes in a zone 3b an upwardly extending tube 10 downstream of the machine 1 and upstream of the liquid circulating pump 5 so that in use, the pressure in that part of the system can influence the liquid level in the tube, the system including also in the zone 3b a compensating container 14 larger than, and arranged near the tube 10. The container 14 is connected into the system by a container inlet duct 15 incorporating a non-return valve 16, and by an outlet duct 17 incorporating valve 18. A temperature increase, in the circulating liquid in the zone 3b results in a volume and pressure increase and opens the valve 16 to allow liquid to pass into container 14. A temperature decrease operates a thermostat 19 which through a time relay or switch 20 opens the container outlet valve 18 at least for a limited period. If a defect such as a leak should develop in the system, the pump 5 will tend to draw liquid from the tube 10 and the fall in level is arranged to operate firstly a contact 12 arranged to operate a warning device, e.g. at the switchboard of the power station, and secondly after a further drop in the liquid level, to operate a contact 13 shutting down the generator. The system shown includes an auxiliary pump 5a, coolers 6a, 6b and filters 8, 9 for the circulating liquid. The system is pressurized through a line 11 by a gas such as nitrogen.

Title: A process for the preparation of starch derivatives capable of swelling in cold water
IPC: C08B30/14
Filed: 1957-03-29
Abstract: 863,574. Starch derivatives. MEIJER'S FABRIEKEN VOOR VERPAKTE ARTIKELEN N. V., O. J. March 29, 1957 [Oct. 3, 1956], No. 10422/57. Class 2(2). Starch derivatives capable of swelling and/or dissolving in cold water are made from a starting material which comprises a starch derivative as hereinafter defined or a starch and a substance capable of converting the starch into one of said derivatives and in which the original starch granules are microscopically recognisable, by increasing the particle size of the starting material in the presence of moisture by shear action in a single stage at a linear pressure of 100 to 10,000 kg./cm. and at a temperature below the gelatinization point of the starting material. The term "starch derivative" means a product obtained by acid treatment in suspension, oxidation, e.g. with hypochlorites, peroxides or persalts, etherification, esterification e.g. with monochloracetic acid or dextrinization to give products which do not dissolve or swell in cold water. An edge runner mill, with either a stationary or rotatable tray, is a suitable apparatus. By subsequent sieving and grinding the desired particle size can be selected. The viscosity of the product can be increased by adding alkali lye, borax or other alkaline agents before or during the process.

Title: A transistor switching system
IPC: F02P3/055
Filed: 1961-03-22
Abstract: 968,030. Ignition systems. ELECTRIC AUTO-LITE CO. March 22, 1961, No. 10465/61. Heading F1B. [Also in Division H3] An ignition system comprises a unidirectional source of current 10, a current consuming device (ignition transformer 20), a transistor 30, a unilateral conducting device D-1, a resistance unit, a main circuit connected across the source comprising in series connection the emitter and collector electrodes of the transistor with the unilateral conducting device and the current consuming device whereby the flow of current therein is controlled by the transistor, a second circuit for reducing the power dissipation of the transistor in which are interconnected the emitter and base electrodes of the transistor through the unilateral conducting device, a secondary circuit in which the resistance unit R3 is connected across the emitter and collector electrodes and switch means 53, 54 connected to the second circuit operable for connecting and disconnecting the second circuit to the source of unidirectional current. The diode D-1 is so connected that its forward voltage drop appears as a reverse bias on the base to the emitter electrode of the transistor. This reverse voltage on the diode D-1 causes both the collector base and emitter base junctions of the transistor to be reverse biased. This in turn causes leakage current of extremely low value in these two junctions so that the power dissipation of the transistor is materially reduced during its "Off " condition. Modifications including various arrangements of a second diode which may be a Zener diode are described. The system may be powered by a D.C. generator or a regulator source of supply for providing a substantially constant direct current for the energization of the primary winding of the ignition coil. The ignition transformer may have a substantially closed core of high permeability magnetizable material preferably of grain oriented high percentage silicon steel, a turn ratio at least greater than 250:1 and a primary winding having a very low inductance and comparatively few turns preferably not more than 80 turns.

A feed mechanism for a grinding machine having a support 12, Fig. 1, for a workpiece W, a movable support 11 for a grinding wheel 13, and a sizing device 30 for the work, comprises means for advancing the wheel support through a predetermined initial distance, means for further advancing the wheel support firstly by coarse and then by fine increments to grind the work to the required size as determined by the sizing device, and means actuated by the sizing device for reversing the advancing means to retract the wheel support and for reversing the means for further advancing the wheel support. The grinding wheel support 11 is movable towards and away from the workpiece on guideways on the machine bed 10 either by a handwheel 81 on a shaft 80 connected by a chain 83 to a shaft 85, in turn, connected by gears 86, 87 to a shaft 60 having a worm 61, Fig. 5, engaging a wheel 62 on a lead screw 40 co-operating with a nut 41 secured to the support 11 or by a motor 89, Fig. 1, connected by gears to the shaft 60. The support is also movable under the control of relay-operated, solenoid-controlled valves automatically and successively rapidly by a piston- and-cylinder device 50, 51, Fig. 5, axially moving the lead screw, at a slower but still fast speed by a piston-and-cylinder device 63, 64 axially moving the shaft 60 to rotate the lead screw for a preliminary fast grinding feed to within, say 0À001 inch of the finished size of the workpiece, in coarse increments by the reciprocation of a piston 111 having a pawl 110 engaging a ratchet 100 on the shaft 80, on which is the handwheel 81, and in fine increments by the reciprocation of a piston 104 having a pawl 103 also engaging the ratchet on the shaft 80. The successive movements are controlled by limit switches 1LS and 38LS operated by the ends of the lead screw and shaft 60, respectively, and the number of coarse increments is controlled by a counter actuated each time the piston 111 is operated. A time dwell to allow " spark out " of the wheel is permitted after the preliminary fast grinding and between each of the coarse and fine increments, the fine increments continuing until the workpiece is to size as determined by the sizing device represented by a caliper 30 which actuates a switch to operate a valve 90 and supply fluid to the opposite end of the cylinder 50, to a fast return cylinder 70 to reposition the shaft 60, and to a piston 121 having a pawl 120 which engages a ratchet 101 also on the shaft 80 adjacent the ratchet 100 and is operated the same number of times as the coarse piston 111 and pawl 110. Shuttle valves may be used for the incremental feeds in place of the pawl-andratchet mechanisms. The arrangement provides for the compensation of the reduction in material of the wheel from wear and trueing.
