Title: Cabling machine
Inventor: NORTENIUS BENGT A
IPC: G02B6/44
Filed: 1991-09-20
Abstract: The present invention relates to a cabling machine for laying optofibres, cables or the like in an oscillating, wavy path around a smooth pull-reliever or into grooves of oscillating, wavy shape extruded around a pull-reliever, so-called S/Z-cabling. The machine includes a pull-reliever reeling-off device, a braking capstan, a fibre reeling-off device or devices, an S/Z-bench for laying the fibre/fibres around the pull-reliever, a yarn spinner for fixating the fibre/fibres on the pull-reliever, and a wheel capstan and a taking-up device for forwardly pulling and taking-up the finished cable respectively, the S/Z-bench including a laying-on tube provided with a laying-on head, wherein the fibre/fibres pass over the laying-on tube and up to and through holes in the laying-on head, where they are laid on the pull-reliever and fixated with yarn taken from the yarn spinner located immediately downstream of the laying-on head. According to a first aspect of the invention, the S/Z-bench (6) includes an aligning mechanism (13) which grips around and guides the pull-reliever (2), and a motor (15) which imparts an oscillating, rotational movement to the aligning mechanism via a transmission (14). The laying-on tube (11) is fixed to or connected to the transmission (14) which imparts an oscillatory, rotational movement to the laying-on tube in a direction opposite to the aligning mechanism (13). A sensor (17) is connected to the transmission (14) and controls rotational movement of the motor (15) and therewith of the laying-on tube (11) and/or the aligning mechanism (13), wherein rotational movement of the laying-on tube is restricted so that the fibre/fi-bres (5) will only be wound onto the laying-on tube (11) to a small extent. According to another aspect of the invention, the pull-reliever reeling-off device (1) and the braking capstan (3) are rotatably mounted and the laying-on tube (11) is freely rotatable and guided by the action of laying the fibre/fibres (5) into the grooves in the pull-reliever (2). The laying-on tube (11) is connected to the transmission (14) and a sensor (17) is connected to the transmission and functions to detect rotation of the laying-on tube (11) caused by the oscillating waveshape of the grooves and causes the reeling-off device (1) and the braking capstan (3) to rotate to perform a correcting function and therewith counteract excessive rotation of the laying-on tube (11) so that the grooves in the pull-reliever (2) in the vicinity of the laying-on head will extend substantially rectilinearly and such that the fibre/fibres (5) extend substantially parallel with the laying-on tube.

Title: Low nox cogeneration process and system
Inventor: BELL RONALD D
IPC: F01K23/10
Filed: 1991-03-13
Abstract: A process and system for low NOx cogeneration to produce electricity and useful heat. Fuel (12) and oxygen (14) are provided to an internal combustion engine (10) connected to drive an electric generator (9), to thereby generate electricity. An exhaust stream is recovered from the engine at a temperature of about 500· to 1000 ·F which includes from about 6 to 15 percent oxygen. Fuel is added to the exhaust stream to create a fuel-rich mixture, the quantity of fuel being sufficient to react with the oxygen and reduce the NOx in said exhaust stream. The fuel-enriched stream is provided to an afterburner (18), and the fuel, NOx and available oxygen are reacted to provide a heated oxygen-depleted stream (20). The oxygen-depleted stream (20) is cooled in a heat exchanger (22). Conversion oxygen (29) is admixed with the cooled stream which is then passed over a catalyst bed (25) under overall reducing conditions. NO is converted to NO2 at the forward end of the bed, and the NO2 then reacts on the remainder of the bed with excess combustibles. Air is added to the resulting stream from the catalyst bed (25) to produce a cooled stream (24) having a stoichiometric excess of oxygen, and the cooled stream is passed over an oxidizing catalyst bed (26) to oxidize remaining combustibles. The resultant low NOx stream can then be provided for venting.

IPC: A44B18/00
Filed: 1991-06-03
Abstract: The invention is an improved process for forming a mechanical fastening prong and the prongs (22) produced thereby.
