Title: Dewatering solids
Inventor: ADKINS STEPHEN JOHN
IPC: B01D21/01
Filed: 2008-07-01
Abstract: A process of providing dewatered solids derived from effluent resulting from the processing of granite or sand and gravel by concentrating an aqueous suspension of solid particles derived from the effluent, comprises the steps of adding to the aqueous suspension at least one organic polymeric flocculent to the suspension thereby forming flocculated solids, allowing the flocculated solids to settle in a gravimetric thickener to form a layer of suspended concentrated solids as a thickener underflow, and passing the thickener underflow to a dewatering stage, in which the process comprises the application of an effective amount of an agent, and in which the agent is selected from the group consisting of free radical agents, oxidising agents, enzymes and radiation. In particular, flocculated solids can be settled to form a bed in which higher solids and/or reduced yield stress can be achieved. Furthermore, when the concentrated suspension is dewatered on a filter press the process can provide a significant reduction in press cycle time.

Title: Method for adjusting media access control parameters in a wireless network
Inventor: DEB BUDHADITYA
IPC: H04W28/18
Filed: 2009-06-02
Abstract: A system for setting WLAN node operating parameters includes at least one access point (AP) radio and a plurality of nodes in wireless communication with the AP radio according to media access control (MAC) parameters. Each of the plurality of nodes has a quality of service (QoS) threshold for wireless communication with the AP radio that is a function of the MAC parameters and includes a controller configured to provide individualized control of the MAC parameters. The controller is programmed to measure current settings for at least a portion of the MAC parameters for the node, input the current settings for those MAC parameters of the node into a WLAN system model to generate a system model output, and adapt a setting of at least one of the MAC parameters for the node to meet the QoS threshold for the node based on the system model output.

Title: Shuttle propelling mechanism for looms
Inventor: WADE WORTH
IPC: D03D49/26
Filed: 1958-03-28
Abstract: 831,031. Picking-motions for looms. AMERICAN VISCOSE CORPORATION. March 28, 1958, No. 10023/58. Class 142(2) [Also in Group XXXV] A device for propelling a shuttle by an explosive charge in which the explosion is initiated by means actuated by movement of the shuttle has means for absorbing, initially, part of the force of the explosion and means for delaying the explosion after arrival of the shuttle in its box to allow time for shedding. In one embodiment (Fig. 4), the shuttle 14 is propelled by a piston 17, 19 in a combustion chamber 15 supplied with fluid propellant by a metering valve 25. The propellant may be detonated by a spark, by a quick acting heating element, or by a second fluid which reacts with the propellant to cause an explosion. The force of the explosion is partly absorbed by a spring 87 that is compressed during the first part of the piston movement and subsequently released by levers 97, 103 as a disc 89 moves to the right with the piston. Alternatively, a double acting oil dashpot may be fitted. This device also checks the shuttle on arrival in the box. The time delay is effected by a disc 43 turned by links 37, 39 secured to the piston and having a pin 47 engaging a slot 48. The disc carries a contact 49 for firing the propeliant. The amount of delay can be altered by varying the position of the contact 49, by altering the length of slot 48, or by altering the weight of the disc. In a second embodiment (Fig. 2), the time delay may be caused electronically. In this embodiment a switch 51 is closed by the shuttle during its flight and completes a circuit to a thyratron 57 which, after a preselected time interval, energizes a sparking plug 31 through a pulse-forming network 67 and an ignition coil 73. According to a third embodiment, the ignition circuit is energized through a bead thermistor when the shuttle closes the switch 51. The chamber 15 may be fitted with a silencer and an air exhaust duct. Specifications 759,562 and 776,100 are referred to.

Title: Digital circuitry.
IPC: H03K23/42
Filed: 1967-03-07
Abstract: 1,150,127. Electronic counters. RADIO CORPORATION OF AMERICA. 7 March, 1967 [14 March, 1966], No. 10763/67. Heading G4A. [Also in Division H3] A bi-stable circuit comprises a pair of inverters 20, 30 cross-coupled from the output of each to the input of the other by way of normally enabled gates 60, 70. The output from the inverter 30 is also coupled to a further inverter 10 (via gate 80) whose output is coupled to the input of the inverter 20 via a normally inhibited gate 90. Under steady state conditions the input clock signals #A, #B are at + V volts and the trigger input T is at 0 volts, resulting in gates 60, 70, 80 being open, and gate 90 being closed. If the circuit is initially in the stable state in which the input to inverters 10, 20 is 0 volts and that to inverter 30 is + V volts, then reversing the states of the input signals at t 1  closes gates 60, 70, 80 and opens gate 90 allowing the input capacitance of inverter 20 to charge to + V volts, thus changing its output to 0 volts. Reversal of state of #A and T at t 2  closes gate 90 and opens gate 60 to discharge the input capacitance of inverter 30 to 0 V. Input #B now reverts to +V volts at t 3  to open gates 70 and 80 allowing the input capacitance of inverter 10 to charge to +V volts. This is the second stable state of the circuit. The next switching sequence of #A, #B, T changes the input of inverter 20 to 0 at t 4 , the input of inverter 30 to + V volts at t 5  and the input of inverter 10 to 0 V at t 6 , i.e. the circuit is back in its first stable state. Each gate comprises a field effect transistor Fig. 3 (not shown) and each inverter comprises a pair of complementary field effect transistors, Fig. 1 (not shown), or a pair of the same conductivity type, Fig. 2 (not shown). The circuit forms part of a counter the second stage being similar to that described above except that the trigger gate 90 comprises two transistors 90a, 100a in series connected to the outputs from inverters 20, 30. Thus a trigger pulse for the second stage only occurs during the time when both outputs are +V volts, i.e. t 4  to t 5 .

Filed: 1927-04-22
Abstract: 277,892. Durand, P. March 22, 1927, [Convention date]. Addition to 215,375. Computing-apparatus. - The semi-automatic weighing-apparatus claimed in the parent Specification is modified by arranging the mechanism used for manipulating the capacity-increasing weights in such a manner as to vary simultaneously the position of an indicator device carrying a number of groups of cost indications corresponding to different prices per unit-weight so as to leave visible in each group only that indication corresponding to the weights used. In the form shown in Fig. 1, a stationary front plate bears fractional weight graduations 2 and is provided with apertures 3 for the display of the principal unit numerals carried upon drums 4 which are moved as described in the parent Specification by the hand-lever 6 used for changing the capacity weights. The front plate also bears a series of cost graduations 7 - - 7‹ and is pierced with openings 16 through which the cost numerals are displayed. These cost numerals are marked on a back plate 8 arranged to slide on guides 9 and connected to the operating handle 6 by a rod 10. Thus, when the handle 6 is manipulated to change the capacity weights the plate 8 is simultaneously adjusted to display the correct cost numerals through the openings 16 in the front plate. In a modification, Fig. 3, the cost numerals on the back plate are arranged in a circular manner and the back plate instead of sliding, receives a circular movement by means of eccentrics 11 and rack gearing 12 connected to the operating handle.
