Abstract: Rigid expanded plastics insulation slab which is adapted, in its width, to the width of a corrugated asbestos cement slab and has, on one side, a corresponding corrugated surface, in which the wave crests and wave troughs extend perpendicularly to the width, in which the edge regions parallel to the wave crests and wave troughs end in an edge wave crest and in an edge wave trough, in which these edge regions are constructed rabbet-like at their end faces, and in which the edge wave crest of one edge region is reduced in width along its outer flank. By a particular configuration of the edge regions of the insulation slab, laying on a roof covered with corrugated asbestos cement slabs is facilitated and definite heat insulation is always achieved in the region of the junction between adjacent insulation slabs, independently of the varying division in the overlapping region of the corrugated asbestos cement slabs. <IMAGE>

Inventor: LUTZ KARL
IPC: F04D13/08
Filed: 1988-03-14
Abstract: The container pump has a sliding sleeve (13) at the bottom end of its housing shell (5), which in the open position frees the inlet apertures (11) at the bottom end of the housing shell (5) and in the closed position, in which it is applied against a base plate (12), closes these inlet apertures. The base plate (12) projects in a radial direction beyond the housing shell (5), thereby sealing the pump off from below. Fluid can thereby be admitted only via the inlet apertures provided on the circumference of the pump's housing shell (5). Displacement of the sliding sleeve (13) is achieved by the provision of thrust pieces (19) on the underside of the sliding sleeve, which in the closed position project downwards beyond the base plate (12) and when the pump is switched on are forced upward against the action of a spring (15) loading the sliding sleeve (13) owing to the downward acting weight of the pump, as a result of which the sliding sleeve (13) is released from its sealing seat on the base plate (12) thereby permitting the entrance of fluid through the inlet apertures (11). When the pump lifts, the sliding sleeve (13) is forced back into its closed position by the spring (15). The sliding sleeve can also be operated manually by an operating device.

Abstract: An improved take-out assembly for removing workpieces from a blow molding machine particularly adapted for blow molding machines having a continuously rotating turn table which rotates about a horizontal axis. The take-out assembly includes a turntable with a plurality of extending pick-up units having suction cup type engaging pads at their ends. Rotation of the take-out assembly turntable is coordinated with the blow molder turntable such that a suction cup pick-up unit is positioned to engage a workpiece at the desired work station. The pick-up units are radially movable to extend and retract to provide clearance during rotation and to properly engage the workpiece at the discharge station. A rotary timing valve is used to conduct a vacuum source to the individual pick-up heads at the desired point in the operating cycle of the take-out assembly. Workpieces being removed from the blow molder turntable are transported by the pick-up assembly into registry with an associated material handling device such as an endless belt type conveyor. The take-out assembly mechanism further includes a mechanism for enabling it to be moved away from the blow molder discharge station to enable manual removal of workpieces which is desirable during machine start up, testing modification, etc.

Abstract: A metal connector for the end of an internally and externally plastics coated metal tube (22,23,24) maintains the metal of the tube, for example aluminium (24), out of contact with the metal of the connector, for example brass, and thereby avoids problems of anodic corrosion. This is achieved by forming the male portion of the connector with a tapered shank (14) over which the tube end is to be forced, and a shoulder (18) to act as a stop for the tube end, the shoulder being of such relatively shallow depth that it abuts the internal plastics coating but not the metal of the tube.

Title: Contact lens disinfection case with locking mechanism
Inventor: MONESTERE MARTIN
IPC: A61L12/08
Filed: 1988-09-15
Abstract: A contact lens disinfection case includes a hollow cylindrical body with two open ends, and first and second end caps mounted on the open ends of the body to define with the body a fluid-tight housing. A contact lens holding basket is mounted on and is removable with the first end cap. An elongate locking member extends through the hollow body and engages the first and second end caps when the end caps are mounted on the body. The second end cap, when mounted on the body, abuts against the elongate locking member and causes it to engage the first end cap, locking it in place and preventing its removal. When the second end cap is not mounted on the body, the elongate locking member is positionable in non-engagement with the first end cap, allowing the first end cap to be removed from the hollow body.

Abstract: A thermal transfer material comprising a support and at least a first ink layer and a second ink layer disposed in the order named on the support, wherein the adhesion strength F₁ between the support and the first ink layer and the adhesion strength F₂ between the first and second ink layers satisfy the relation of F₁ > F₂ at 90 °C. The thermal transfer material also provides a peeling strength of 1 - 5 g/cm at 90 °C. Two color recording is effected by superposing the thermal transfer material on plain paper, applying a pattern of heat and separating the thermal transfer material from the paper while changing the time from heating until the separation, i.e., temperature at the time of separation. Sharp edge-­cutting of the heated portion and the selective transferability of the second ink layer are ensured by the definition of the peeling strength.
