Title: Heat exchanger tube support matrix - has short cylinders spaced by plates which slot in support plates
IPC: F16L3/223
Filed: 1973-04-20
Abstract: A method of supporting and separating bundles of straight parallel tubes, such as are used in heat exchangers. The body of the exchanger is divided by plates, parallel to each other and the longitudinal axis of the exchanger. Chains of short cylindrical rings connected by spacing plates are supported at an oblique angle by the set of parallel plates, the spacing plates interlocking in short saw cuts in the ring spacers. The assembly forms a matrix of short cylinders through which the long tubes of the exchanger pass, but since the matrix cylinders and the tubes are not rigidly connected, the tubes may expand and contract in length freely.

Title: Air treatment system for paint spraying booth - recycles washing liquid through heat exchangers to heat incoming air
IPC: B05B16/60
Filed: 1974-12-24
Abstract: The operating system is particularly for a painting booth, into which a given quantity of conditioned air is delivered, the air passing through a liquid washing unit as it is discharged. The washing liquid is recycled via a heat exchanger, through which a heat conductive medium passes. The latter then passes through a second heat exchanger in the incoming air passage before the air reaches the booth. The medium can be compressed between emerging from one heat exchanger and entering the other, and then expanded after emerging from the second heat exchanger. The operating conditions of the heat exchangers are interchangeable to suit air and liquid temperatures and the desired temperatures inside the booth.

Title: Window actuating handle with mechanism protector - has square plug with groove for shearing under excessive force
IPC: E05B17/00
Filed: 1975-07-22
Abstract: The actuating handle rotates within a rosette and this handle is coupled to the driving pinion of the window locking mechanism. A weak section is deliberately designed into this mechanism. This ensures that in the case of an overloading and failure the weak component is readily dismantled and replaced without dismantling the whole mechanism. The handle shank has a square central hole into which a square plug fits whose other end is connected to the square hole of the pinion. A neck (8) is machined into this plug and this weak position is a rounded groove which covers the whole circumference of this plug. In case of jamming this weak spot is sheared and this pin is readily replaced by removing the handle and inserting a new plug.

Title: Turbodrill for directional drilling of well bores - exhibits no decrease in turbine clearances as bearing taking reaction on bit wears
Inventor: IOANNESIAN R A
IPC: F16C39/02
Filed: 1975-08-07
Abstract: A turbodrill for use in directional drilling of walls is claimed including a first thrust bearing for taking the reaction on the bit and a second thrust bearing for taking the hydraulic load applied to the rotor shaft as a result of the pressure drop in the turbine. The shaft is assembled from endwise-interconnected sections and includes mechanism between the thrust bearings which transmits torque between two adjacent sections of the shaft and which is elastically deformable and relieves the second bearing of hydraulic load by transmitting it to the first bearing. The axial clearance between the rotor and stator blades does not decrease in response to wear of the bearing taking the reaction on the bit, so the drill can be used until the bearing is completely worn down.
