Title: Method and apparatus for treating sewage
Inventor: GARRETT MICHAEL ERNEST
IPC: C02F3/22
Filed: 1982-10-07
Abstract: In order to prevent bacterial formation of hydrogen sulphide in a gravity sewer, the sewage flowing therethrough is oxygenated. A part of the flow is diverted from the main sewer through a conduit 6 into an oxygenator 10 that includes a well 16 having a pipe or tube 18 inserted therein. The well 16 and pipe or tube 18 define a downward leg 12 and an upward leg 14 for the sewage. Flow of sewage through the oxygenator is made possible or assisted by the introduction of a multiplicity of oxygen bubbles into the bottom of the upward leg 14, which bubbles dissolve as they ascend the upward leg 14. Oxygenated sewage flows from the upward leg into a second conduit 8 and back to the gravity sewer. <IMAGE>

Title: Electrical resistance seam welding apparatus and electrode roller and welding-current supply means therefor
Inventor: PORTMANN NIKLAUS
IPC: H01R39/64
Filed: 1985-11-21
Abstract: The apparatus described is so constructed that narrow can bodies having an internal diameter of 52 mm for example can be produced from rounded blanks by welding the edges of the blanks. The supply of welding current to the electrode roller is effected through copper caps, a clamping member, contact members disposed at each side thereof, contact jaws silver contact segments and peripheral surfaces of wide hubs which are provided on the electrode roller. The contact jaws engage the hubs of the electrode roller at both sides of the roller from above and below, as a result of which there is a large area for the transmission of current and a low specific contact pressure. The hub surfaces, which form the actual contact surfaces of the electrode roller, are continuously lubricated through felt lubricating segments. The contact pressure of the contact jaws can be adjusted in a simple manner by means of a screw. The whole apparatus and particularly the electrode roller are extensively cooled internally by a special cooling device.

IPC: E04C3/02
Filed: 1986-11-27
Abstract: A structural metal member which may form part of a lintel or beam for example has plaster or mortar keying means (13) formed without substantial removal of metal. Each keying means has a central slot (14), the borders (15, 16) of which are deformed out of the general plane of the metal to protrude in opposite directions, forming an obliquely angled passageway (20) to guide settable material such as mortar or plaster through the keying means.

Title: Optical temperature transducers
Inventor: OXLEY NEIL ANDREW
IPC: G01N21/15
Filed: 1986-12-22
Abstract: The presence of contaminants on the lens (2) of a radiation temperature transducer is determined by providing a means of measuring the electrical resistance across the external surface of the lens of the transducer e.g. using electrodes on the surface of the lens or extending through the lens to emerge at its outer surface. Thus, at first installation or at the onset of an operation when the lens is known to be clean, a high resistance is measured across the surface of the lens and which becomes a datum. As contaminants build up on the lens a progressively lower resistance is measured and the arrangement can be such that either a signal is provided when contaminants have built up to a sufficient degree to generate an unacceptably artificially low temperature reading or the arrangement can be such that an automatic compensation factor can be added to the output from the transducer in accordance with the degree of build up of contaminants on the lens to ensure that an accurate temperature reading is maintained irrespective as to the degree of build up of contaminants.
