Title: Easily scatterable fertiliser prodn. plant - includes reservoir and mixer separated by dosing container
IPC: A01C3/00
Filed: 1978-10-28
Abstract: Appts. is described for prodn. of fertiliser from organic materials that are liquid or have a high liquid content e.g. manure or clarification sludge and at least one solid mixing component e.g. burnt lime. There is a collecting container for the manure, a mixer, and input and output devices for liquid and solid components. A dosing container is interposed between the collecting container and the mixer, the capacity of the dosing container being less than that of the mixer. The mixer has force-mixer fitted with stirrer and input devices for the burnt lime and for finely ground straw or turf. Incorporation of burnt lime etc. into the manure reduces odour problems, but raises the risk of overliming the soil. Incorporation of the dosing container into the apparatus reduces the risk of overliming.

A perforated water catchment and removal channel (5) may be provided at the bottom edge. Fibres pref. run vertically. This does not give rise to diffusion problems, and is architectural acceptable, without appreciable increase in cost.
Patent DE-2901252-A1 (DE)
Title: Positive hook fastener for fur or synthetic skin garments - has L=shaped closure pieces partly of magnetic material allowing easy handling
Inventor: MADL JOSEF
IPC: A41F1/00
Filed: 1979-01-13
Abstract: The overlap and underlap of the coat etc can be fastened by the closure members (1, 2) which are each L-shaped with a longer and shorter arm (3, 4:5, 6) with the longer arms (3, 4) designed to fasten beneath the overlap and underlap. The shorter arms (5, 6) meanwhile are to engage like hooks wherein one arm consists at least partly of a magnetic material whilst the other arm consists at least in part of a magnetisable or magnetic material. The L-shape design ensures a secure hook fastening whilst the frictional forces caused by the mutual magnetic attraction of the shorter arms prevents accidental opening. Authorised opening however, is easy without strain on the surrounding skin since a suitable choice of effective magnetic forces allows the two parts to move apart parallel to the two arms and then separated.

Title: Measuring and monitoring short term stresses in concrete - using mercury-filled pressure pad connected to indicator capillary
Inventor: GLOETZL RAINER
IPC: G01L7/02
Filed: 1979-02-09
Abstract: A pressure measurement device for measuring and monitoring short duration stresses in concrete consists of a pressure and (1) placed on the concrete and connected to a measurement device (6) via a pipe (3).

Title: Spark ignition IC engine - has turbocharger and valves, timed to give different expansion and compression ratios
Inventor: GOESCHEL BURKHARD DR ING
IPC: F02B1/04
Filed: 1979-03-29
Abstract: The engine has a piston (2) reciprocating in a cylinder (1) with cam operated inlet and exhaust valves. The exhaust valve opens before the end of the expansion stroke to reduce the effective expansion ratio. The inlet valve closes after the commencement of the compression stroke to reduce the effective compression ratio. The timing is so set that the effective compression ratio is less than the effective expansion ratio. The theoretical or geometric expansion ratio is greater than 9 to 1. The engine is equipped with a turbocharger (13). The combination of these features increases the efficiency without loss of output.

Title: Heat exchanger matrix made with meltable pattern - on which metal is deposited electrolytically or chemically
Inventor: ZLOTEK SEN RUDOLF ING
IPC: C25D1/08
Filed: 1980-05-07
Abstract: Heat exchanger matrix for a vehicle cooling radiator air conditioner etc., wherein a set of passages for coolant liq. are interspersed with air passages, is made by first forming a positive pattern from readily fusible metal or other low m.p. material such as wax. This pattern is coated with a suitable thickness of metal by electrodeposition or chemical deposition. The pattern is then melted and removed, leaving the metal exchanger matrix. Auxiliary features such as header tanks, inlet and outlet pipes, can be produced simultaneously in situ during the same operation, or made separately for subsequent attachment. All the exchanger metal used appears in the final product, leaving no scrap. The matrix needs no brazing, welding, pressing or heat treatment, and its unitary stress-free structure is highly resistant to vibration. The matrix may be of complex form or incorporate a sequence of differently shaped passageways.
