Title: Continuous concrete pipe prodn. on site - with casting device drawn along trench to form top and bottom halves together
Inventor: KELLER GEORG M
IPC: F16L1/038
Filed: 1978-02-20
Abstract: Continuous cement type pipe is produced on site in an open trench. A sliding carriage (with feed inlet) moves it along the trench, a casting device moulds concrete into the lower half of the pipe on the trench floor, and has a rigid cylinder which is convex on top. The carriage is drawn along the trench to move the casting device and cylinder and to mould the top half of the pipe, the material is poured into the inlet forming top and bottom halves of the pipe which remains stationary. The freshly formed top half (produced by the clydiner) is thereby left unsupported, while the top half is moved off the cylinder a form which is open underneath is left behind; this form is cured when the cylinder is removed from the top half and material for the top half is supported by that form until is cures. The form remains permanently in the pipe. Process saves cost and labour of stripping a mould; there is no restriction in dia. and formation of mould marks as weak areas is eliminated. Used for corrosion resistant applications.

Title: Angle coder for aircraft control surface servo - sends digital word defining position of disc linked to pilot control
Inventor: GIEGERICH WOLFGANG
IPC: B64C13/50
Filed: 1979-05-15
Abstract: Movement of a pilot's control, in an aircraft, rotates a disc, via a crank and rod. The angular position of the disc is sensed by a radial row of fixed detectors aligned with marks on the disc. The marks are spaced at equal angles, e.g. on a spiral, so that for any angular position of the disc, one detector is operated. Each detector is connected to a coder which sends a digital word to the position servo for the control surface. Alternatively, each mark carries a unique address which is read by its detector and sent to all the coders. Each coder is programmed to recognise its own address. When it receives it, it sends a digital word to the servo. For reliability, a duplicate set of detectors and marks on the disc is used with a duplicate set of coders.

Title: Concrete mixture batching plant - has automatic consistency regulation process, which adds water dependent on values recorded in schedule
Inventor: RAPP JOACHIM
IPC: G05D24/02
Filed: 1980-01-19
Abstract: The process regulates the water supply in a concrete batching plant, measuring the consistency of the material mixed by its electrical resistance or by the power absorbed by the mixer drive. In a first operation, a relatively large first quantity of water is delivered, this being reduced to allow for the maximum possible moisture content of the additives, together with a number of equal smaller quantities of water, so as to give a set consistency of the concrete. The consistency values achieved after adding each quantity of water, and the corresponding absolute water quantities, are recorded in a schedule. All subsequent batches are prepared using an initial quantity of water greater than the first one referred to above, the actual consistency being then determined and the adjacent consistency values in the schedule found, and used by interpolation to determine the actual water wauntity. Values a adjacent to the desired consistency are found in the table, the total water quantity necessary to reach this consistency being likewise found by interpolation and the necessary balance of water added.
