Title: Thermoplastic molded part with stress reducing juncture
IPC: B29C35/00
Filed: 1982-04-23
Abstract: An improved thermoplastic molded part (30) is disclosed including a stress reducing juncture (40) which is operative to reduce differential shrinkage of the molded plastic, which would otherwise develop due to uneven cooling of the plastic to room temperature, thereby inhibiting warping of the part. More specifically, an improved thermoplastic molded part (30) is provided including at least one wall member (34) formed unitary with another structural element such as another wall (36), flange or boss area. The thermoplastic part is further provided with a stress reducing juncture (40), defined by an elongated trough-like recess (42), located in the wall member (34) adjacent the other structural element (36). Preferably, the recess (42) has a width approximately equal to the width of the wall member (34) and a depth equal to approximately one half that width. The recess functions to decrease internal stresses that normally develop due to differential shrinkage of the molded plastic during cooling to room temperature. By reducing internal stresses, unwanted warping of the part is minimized. <IMAGE>

Patent GB-2149915-A (GB)
Title: An improved method of ultrasonic inspection
Inventor: KAPRANOS PLATON ATHANASIOS
IPC: G01N29/11
Filed: 1983-11-02
Abstract: In the ultrasonic scanning of a material, a compressive stress is applied to the material. The reflected signals obtained during the application of the compressive stress are compared with the reflected signals obtained in the absence of such stress. A difference in the amplitude of the compared signals is indicative of the presence of a flaw in the material. The effect can be used to distinguish between signals resulting from cracks in austenitic welds and signals arising from the metallurgical structure of such welds, the latter being unaffected by the application of compressive stress, and the former being closed by the compressive stress.

Title: Fluid flow tracing and monitoring of sewage-treatment-plant operation
Inventor: BROWN LESLIE
IPC: G01F1/704
Filed: 1984-07-02
Abstract: A method of tracing fluid flows is described in which a tracer is metered into a flow at one point and flow samples taken downstream of the addition point are subjected to high performance liquid chromatography and spectroscopic analysis to determine the concentration of the tracer therein. The results are used to determine the flow rate of the fluid at the injection point and/or the degree of dilution of the flow by additional fluids. Bromophenol blue is used as the tracer in sewage treatment plants where flow results are compared with known dilution profiles for the plants to check for operational abnormalities. Flow dilution measurements may also be combined with uric acid, hippuric acid or creatinine concentration measurements to monitor the progress of biodegradation reactions throughout the biodegradation stage of the plants. The measurements may be carried out automatically and used to control the operation of the plants.

Title: Air cooled gas turbine aerofoil
Inventor: LIVSEY DUNCAN JOHN
IPC: F01D5/18
Filed: 1984-12-01
Abstract: A hollow turbine blade has cooling air feed passages 14 in the wall defining the central cavity 12. The wall surfaces 14b of the feed passages slope away from the central cavity 12 in a diverging manner, so as to reduce the step difference in metal thickness between the passages 14 reletive to the thickness of metal dividing each passage 14 and the central cavity 12. The temperature gradient between the blade external surface 16 and the wall surface 18 of the central cavity 12 is thus also reduced, avoiding thermal stresses. <IMAGE>

Patent GB-2158201-A (GB)
Title: Improvements relating to valve assemblies
Inventor: MAYO SEAN ALFRED
IPC: F16K31/08
Filed: 1985-04-04
Abstract: A valve body 1, forming part of a fluid supply pipe of a central heating radiator, carries a valve incorporating a magnetic plunger 3 biased down onto a valve seat 6 by a spring 7. An operating pulse passed through a coil 9 is sufficient to enhance the magnetic field of a permanent magnet 13 to draw the plunger 3 upwardly to remove the valve head 4 from the valve seat 6. When the plunger 3 is in the raised position the magnetic field of the magnet 13 alone is sufficient to hold the plunger 3 in the raised position against the bias of the spring 7. A pulse passed in the opposite direction through the coil 9 will create a magnetic field in opposition to that created by the magnet 13 so that the overall magnetic field will then be insufficient to overcome the bias of the spring 7 and the plunger 3 will return the valve to the closed condition. <IMAGE>

Title: A roller bearing cage
Inventor: OLSCHEWSKI ARMIN
IPC: B29C45/44
Filed: 1985-07-03
Abstract: A plastics roller bearing cage has two end rings and axially extending bars 11 forming pockets 12. Each bar 11 has a projection 16 on one side protruding into one pocket to prevent a roller in the pocket from dropping out. To keep tooling costs down by the use of one piece radially movable sliders 18 and yet allow the use of relatively rigid plastics material, each bar 11 has a recess 17 on the other side. As the sliders 18 are withdrawn the recess 17 of the next adjacent pocket allows the bar 11 to be elastically bent so preventing the projection 16 from being broken off. <IMAGE>
