Title: Apparatus add method for the treatment of effluent
Inventor: DICKINSON JOHN GEOFFREY
IPC: B01D17/00
Filed: 1992-05-30
Abstract: A mobile apparatus for treating industrial effluent stored in a tank (16) on site comprises a wheeled chassis carrying a suction source, a series of storage tanks and a separator (23), which may be a belt press or centrifugal decanter, and separates liquid and solid fractions. Initially any oil floating on the surface in tank (16) is drawn into auxilliary tank (15), then the main contents of tank (16) is drawn into tank (14). Upper and lower level detectors (14a, 14b) in tank (14) control the flow into and out of tank (14) to hold the liquid surface between the two levels, liquid flowing only into or out of tank (14) at one time. The liquid is drawn from tank (14) by pump (19) through a muncher (18), which breaks up large solids, and fed to a further tank (20), also provided with level detectors which control pump (19) to maintain a level between (20a) and (20b) to supply separator (23). Solids are removed from separator (23), either as a thick pumpable slurry by pump (32) or by a screw conveyor feeding a belt conveyor. Liquid is removed from separator (23) by a pump (25) to tank (27) with more level detectors which control discharge from tank (27) via pump (28) or valve (U) to a sewer. <IMAGE>

Title: Mat manufacture
Inventor: HEDLEY TERENCE MICHAEL
IPC: B29C43/12
Filed: 1995-09-01
Abstract: A mat particularly a washable dust control mat, having a fabric layer (2) and a rubber backing layer (4) with a border extending beyond the fabric layer is made using a press which heat-cures the rubber and adheres it to the fabric and employs an inflatable bag to apply pressure by pressing the layers against a heated platen, wherein a frame (14) defining the extent of the border is located between the bag and the platen, and wherein the bag applies pressure to the assembled layers including the border portion of the backing layer. The frame can act as a dam for preventing outward movement of the rubber and provide an integral thickened border; in some cases it also provides a guillotine for trimming the rubber during pressing.

Title: Hinge mechanism for a clamshell-like device.
Inventor: SLOW WEE MIN
IPC: E05D11/08
Filed: 1996-08-19
Abstract: The first hinge (A) operates upon application of a first torque to pivot a panel (14) , such as the screen of a laptop computer, through a first range of motion (to 14") beyond which the first hinge (A) is opposed by a restrictive force. The second hinge (B) operates upon application of a second torque greater than the first torque, but less than the restrictive force. The panel (14) is then pivotable through a second range of motion (60). The hinges thus work sequentially to pivotally couple the panels (12, 14) of a clamshell-like device through substantially 360 degree rotation (* small Greek theta *2 ). The hinge (A) includes a friction bushing which sets the first torque. The hinge (B) includes a normally locked pintle which is released by being cammed axially against spring bias under the second torque.

Title: Complex and elementary integer operations
Inventor: HENSON ANDREW ROBERT
IPC: G06F9/318
Filed: 1996-10-18
Abstract: A computer program contains an "isize" directive, in the body of the program or as a field in the program header, indicative of the required bit size I for integers used by that program. A processor can perform integer operations on integers having up to a particular number N of bits as "elementary" operations, and on integers having a larger number of bits as "complex" operations. If an isize directive is not included, a default value of, say, 32 is assumed. The isize directive may be global, or on a per routine, per integer, or per expression basis.

Patent GB-2309130-A (GB)
Title: Arc welding; switch mode power supply
Inventor: GEISSLER STEVEN
IPC: B23K9/067
Filed: 1997-01-07
Abstract: An arc welding power supply includes a switching type inverter or converter with an adaptive hot start circuit enabling additional current to be supplied at start up, the amount of additional current being dependent on the output voltage. The supply may have a V-A characteristic, Fig.9, with a constant voltage portion 901 leading via a "droop" portion 902 to a constant current portion 903 which is operative at output voltages found under typical welding conditions. A "dig" portion 904 provides increasing current with decreasing voltage below a dig voltage threshold, the maximum dig current being user adjustable. At start up, the welding current is increased to twice the user set value for a predetermined period, plus additional current spikes as the output voltage crosses above and below the dig threshold, Fig. 10. In a series resonant converter (Figs. 1-6) which controls converter switching to give a desired constant current output, the voltage on a resonant tank capacitor and the current through the converter switches are sensed to determine if a dangerously high voltage would be generated on the capacitor during the next cycle of converter operation. The converter switches are not enabled for the next cycle until the capacitor voltage has bled down to a safe level. The converter may be used for induction heating, or may be combined with additional circuitry (Fig. 8) to provide a welding supply having the aforementioned V-A characteristic and start up operation.
