Abstract: A garden memorial arch floral material holder is installed in a cemetary with two ground penetrating stake assemblies and a flora holding assembly. The flora holding assembly comprises a plurality of rods connected in tandem and the rods have sufficient flexibility to elastically deform from an unstressed straight linear aspect to an arcuate aspect encompassing a semi-circular arch configuration, without permanent deformation. Rods of different length may be connected in different combinations to provide different arch assembly lengths. The rod connections have abutments limiting telescopic overlapping and friction detents to resist disconnection. Each of the two stake assemblies has a horizontal brace portion to be engaged by foot to force a stake portion into a cemetery ground, to engage the ground to limit the penetration, and to provide vertical alignment. The stake assemblies are in spaced apart parallel planes that are perpendicular to the arch assembly to stabilize the holder.

Abstract: Overhead conveying system trolleys supported by canted driven rollers engage on and form spiral loci of engagement with a rotated drive shaft in a powered section, and each has a top wheel used to lift the driven rollers off of the drive shaft as the trolley enters a gravity rail section where the wheel is supported on a rail and where a step feeder releases trolleys one at a time from or along the gravity rail section. A pivoted step feeder arm in a receiving and holding position receives the wheel of the lead trolley, which actuates a release limit switch, to cause the arm to rotate and release the trolley. In this release position, the retention abutment mounted on the accumulation side of the arm, prevents any following trolley from actuating the release limit switch. The arm remains in the release position until a second limit switch is actuated by the released trolley moving away, to cause the arm to rotate to the receiving and holding position to receive the next lead trolley.

Abstract: The method and apparatus sucks the entire combustion air volume in laterally with respect to the direction of flow of the air current with the help of the impulse of a fuel gas jet out of the air current into a mixing pipe and the formation of a differential pressure between the mixing pipe input and the waste gas output into the air current is prevented with the help of current guidance sheet metal pieces. The burner is arranged in a shaft-like housing, the fuel gas nozzle and the lower part of mixing pipe are surrounded by a pot-shaped current guidance sheet metal piece. A cylindrical current guidance sheet metal piece adjoins the cooled burner plate. The burner which, for example, can be used in dryers, for heating room air with so-called make-up air units and in gas water heaters, operates completely independently of the air flowing around it in a wide heat load range, without any change in the air coefficient. Because of the super-stoichiometric premixing of the burning gas with the air, the NO.sub.

Abstract: A continuous casting method in which molten metal is continuously poured into a moving mould cavity formed between a rotary casting wheel having a peripheral casting groove and a moving belt partially covering the peripheral casting groove. The cast billet which has been solidified at least outer surfaces thereof is continuously pulled out from the moving mould cavity by means of pinch rollers which are rotated at a peripheral speed greater than that of the rotary casting wheel.

Abstract: A method of repairing the housing of a control rod driving system of a nuclear reactor, the housing being inserted through the wall of a pressure vessel of the reactor into a cylindrical sleeve secured to the inner surface of the vessel, which housing is jointed by welding to the cylindrical sleeve. The method comprises the steps of: cutting the housing in the circumferential direction of the housing at a position defined between the weld joint and the inner surface of the reactor vessel and surrounded by the cylindrical sleeve, thereby to divide the housing into a first housing part still attaching to the weld joint and another removable housing part; removing the removable other housing part; inserting a second housing part into said cylindrical sleeve through the wall of the nuclear reactor vessel; and uniting the first housing part and the second housing part by welding thereby to form a new housing for the control rod driving system.
