Title: A heating and insulation arrangement for a network of installed pipes and method.
Inventor: MONTIERTH GARRY L
IPC: F16L53/38
Filed: 1988-02-02
Abstract: A technique for installing and replacing, if necessary, readily bendable electrical heat-tracing cable on and insulating a network of installed pipes including straight sections, straight joints, and elbow sections is disclosed herein. In accordance with this technique, initially provided heat-tracing cable is installed in individual continuous sections along the length of and adjacent to the straight pipe sections, joints and elbow sections. Routing guides are placed over and/or under lengthwise surfaces of at least those segments of the heat-tracing cable adjacent to the joints and elbows and retained in place along with the cable itself. With the cable and routing guides so retained, a layer of thermal insulation is placed over the network of pipes as well as the cable and routing guides so that opposite ends of individual cable sections are readily accessible for connection with the source of electrical power or a section of replacement cable.

Abstract: PCT No. PCT/GB88/00434 Sec. 371 Date Jan. 22, 1990 Sec. 102(e) Date Jan. 22, 1990 PCT Filed Jun. 2, 1988 PCT Pub. No. WO88/09740 PCT Pub. Date Dec. 15, 1988.A sewage treatment plant for use aboard ship comprises a vacuum assisted fresh water flush system delivering sewage to a collection tank. Sewage is collected from the collection tank in batches for treatment. The sewage first enters a settlement tank and is then transferred to an aeration tank. After aeration, treated sewage is then transferred out in batches. The batch processing overcomes the difficulties of operating a continuous flow arrangement on a moving platform where liquid can move back and forth, which presents difficulties in controlling the level of biological activity. A controlled amount of sewage transferred to the aeration tank is diluted with grey water. A sludge storage tank is provided and suspended solids probes are provided in the aeration and settlement tanks such that sludge is automatically withdrawn from these tanks to the storage tank to maintain the level of suspended solids within predetermined limits. The sludge storage tank is provided with aerators and its temperature is controlled such that aerobic digestion renders the sludge inert. Small batches of aerated liquid are drawn from the aeration tank into a chlorination tank via a separation system at controlled intervals between successive sewage batch transfers from the collection tank to the aeration tank via the settling tank prior to discharge from the plant.

     Abstract 
     In the process described, a compressed gas is withdrawn from the cylinder during a working cycle, temporarily 
stored, and introduced into the cylinder, together with the fuel, during the next working cycle. The process comprises the 
following steps: a) timed withdrawal of a small quantity, in particular 2 to 6 cm³, of hot compressed gas through a valve 
which opens into the combustion chamber of the cylinder, b) storage of the hot gas withdrawn in a chamber of the valve, c) 
injection of fuel into the hot gas, d) blowing of the stored fuel-gas mixture through the valve which opens into the cylinder. 
The process is carried out by a device which has an insufflation valve (2) with a chamber (18) facing toward the valve and 
a chamber (20) facing away from the valve, and a valve (16) which opens into the combustion chamber of the internal com­
bustion engine and controls the gas exchange between the combustion chamber (3) and the chamber (18) facing toward the 
valve. Said chamber (18) serves as a storage reservoir (4) for the gases withdrawn from the combustion chamber (3). The 
valve (16) is actuated by a drive element (14) which delimits the chamber (20) facing away from the valve. The chamber 
(18) facing towards the valve is connected to the chamber (20) facing away from the valve via a non-return valve (32). A 
pressure-generating unit (5) delivers fuel to the chamber (20) facing away from the valve.

Abstract: In a control housing for an air brake installation of a vehicle, a bleeder valve may ice up in cold temperatures due to the moisture contained in the air flowing through the valve. To avoid such icing-up, only the shut-off part (4) of the valve is selectively heated up by means of a PTC resistor heating device. By virtue of the heating-up only of the movable shut-off part of the valve, extremely little heating energy is sufficient for reliable prevention of icing-up of the valve. <IMAGE>

Abstract: For the joining of heating pipes (1; 2), which are composed of a medium pipe (3) made of steel, a jacket pipe (4) made of plastic and foam filler (5) in between, the medium pipes (3), which are exposed at the ends, are welded (6) in a known manner. A bridge (8) is then placed over the gap between the foam fillers (5) and supported on the two previously exposed ends (7) of the foam fillers. The bridge (8) is composed of a sideways U-shaped profile made of aluminium sheet; its arms are pressed into the foam. The gap between the jacket pipes (4) is then closed by flush insertion of a jacket pipe transition piece, the transition piece being connected to the two adjacent jacket pipes (4) by seams, in particular welded seams, and being closed at a longitudinal section. In this case, the bridge (8) serves as a support on said longitudinal section so that the transition piece does not shrink and sink in due to the heating on the longitudinal seam. Subsequently, the cavity is filled with foam. <IMAGE>

Abstract: A multi-disc brake suitable for an aircraft has a stack of rotor and stator discs in which the discs (5-9) of a set at one end of the stack each have a greater allowance for wear than the discs (1-4) of a set at the other end of the stack whereby the group of discs (1-4) are removed together from one end of the stack as a fully worn group at a brake servicing operation. An unworn group of discs is added to the other end of the stack. 
     The provision of selective variation of wear allowance in the initial construction of the brake allows it to be lighter and more compact than conventional brakes of similar performance and expected disc wear life.
