Title: Inclined plate clarifier - for separation of solids from liquid suspensions
IPC: B01D21/00
Filed: 1971-10-30
Abstract: The unit is a settling chamber where velocity of the fluid is reduced to a level when solids separate by gravity and are collected on the surface of parallel plates in two banks sloping to the middle forming a "V" in cross-section. The angle of plates is 35 to 60 degrees to the horizontal. Parallel plates are approx. 2.5 cm. apart and in the middle there should be a clearance of 7.6 cm. It is essential that the liquid flow over the plates is laminar and uniform. Under such conditions back mixing does not take plce. To aid sepn. it is possible to add coagulants. Capacity can be increased by installation of masking plate at entry to the bank of parallel lates.

Title: Rod type fuel element - with glass interface between fuel and cladding
Inventor: GREGORIUS KLAUS DIPL PHYS
IPC: G21C3/20
Filed: 1971-11-09
Abstract: In a rod type fuel element the interspace between the fuel and outer cladding is filled with glass to provide a H2 impervious barrier with voids which, dependant on their size and quantity, limit the fuel swelling rate. Metal oxides and alkali carbonates included in the glass in the fabrication stage gasify to fill the voids and during operation exert a balancing press. to that exerted by gaseous fission prods. The interspace layer lends itself to the inclusion of metal hydrides to act as moderators and also excess reactivity compensators such as B or rare earths such as Gd, and Sm. Thermal conductivity can also the enhanced by Mo, Fe or Ni additives.

Title: Mandrel for tube rolling mill - has hard weld deposit sleeves for calibration purposes and lubrication channels
Inventor: DORP WALTER VOM
IPC: B21B25/00
Filed: 1973-06-21
Abstract: The mandrel used for sizing the bore of the tube blank which is rolled in successive sizing rolls is a steel rod with integral welded sleeves. The diameter of the sleeves is the same as that of the mandrel rod. The mandrel has a central bore for supplying lubricant. Radial bores ensure outlet of this lubricant into the space between the mandrel outside diameter and the bore diameter of the tube blanks. The mandrel can be parallel or its outside diameter of the deposit welded calibrating sections can increase along the mandrel for final sizing. A final smoothing and sizing section can be connected to the mandrel. The mandrel is relatively cheap to produce because the main body of the mandrel is made of cheaper material than the calibrating sections.

Title: Trim flap for fast motor boat - mounted away from hull line behind water intake for max. effect
Inventor: RHODA RALPH ALLEN
IPC: F01B23/04
Filed: 1973-07-16
Abstract: Fast motor boats, powered by an impeller driven water jet have low pressure areas on the hull immediately behind the water intakes. This reduces the effectiveness of the trim flaps at fast speeds. The water intake is improved by extending its bottom surface out of the hull line to position the trim flap surface back into the water flow. The flap extends over the width of the intake and some way backwards. The intake can be fitted with flwo guides set at the planing angle of the boat to streamline the intake flow and further reduce the low pressure area. This also reduces drag.
