It incorporates a feed tube which directs all the rain water from the roof to the anchoring pole in the ground. The section of the guide tube above ground branches at the top which links it to the main water supply for use during a long period of drought. The guide tube is shaped with a knee under the ground so that the upper and lower sections run parallel and vertical and the two bends subtend and angle of 120 degrees.
Patent DE-2366020-A1 (DE)
Title: Fabricating thermoplastic layflat film - in two layers oriented at right angles
Inventor: SUDO MICHIO
IPC: B29C48/10
Filed: 1973-02-24
Abstract: In a process for fabricating a laminated cylindrical film with a plastic resin base, the laminated structure consists of three layers, the inner layer being stretch oriented transversely and the outer layer being stretch oriented longitudinally. The median layer is formed from a film having a lower fusion point than the inner and outer layers, and consolidation is brought about by heating to a temp. slightly below the fusion point of the median layer so that it is bonded to the other two layers. The three layers may be extruded from annular concentric orifices, and orientation in perpendicular directions gives greater strength and enables thinner films to be used for a given weight. The three films are extruded from concentric orifices. The outer layer is then stretched longitudinally between two sets of rolls while the inner film is expanded by a rotating mandrel, the film being then cooled rapidly and flattened. The outer and inner layers may be of a high m.pt. polyolefin while the median film may be of e.g. ethylene/vinyl acetate or ethylene/acrylonitrile copolymers.

Title: Polycrystalline diamond prodn. from diamond powder - at very high temp. and press. using diamond grains of different size and additives
Inventor: WJENPRINZEW WLADIMIR IWANOWITS
IPC: B01J3/06
Filed: 1974-01-02
Abstract: Polycrystalline diamond prodn. by applying high pressure to diamond powder at high temps. is improved in that the temp. is 2700-3700 degrees C (pref. 3100-3700 degrees C) and the pressure is equal to that at which graphite is converted into diamond, i.e. 120,000-170,000 atm. Alkaline earth cpds. can be added. Diamond grains of different size are mixed together. The application of higher press. and temp. compared with the known methods of producing polycrystalline diamonds improves the mechanical strength of the products, which are suitable for use in drilling tools. The wearing resistance is increased by the alkaline earth additions and by the use of diamond grains having different size. The pref. additives are fluorspar, limestone, chalk and talc; they are pref. applied in layers below and above the diamond powder layer. Pref. two diamond powder fractions are used having the size of 0.1-2.0 mu and 5-60 mu respectively; these fractions are used in a weight ratio of 20-80:80-20, pref. 50:50.

Title: Electro-mechanical mixer unit for liquids - has electronically controlled magnet for selecting flow ratio
Inventor: ARNDT HEINRICH
IPC: G05D23/13
Filed: 1974-03-05
Abstract: A mixer unit for liquids of different temperatures has an electronic regulator which is linked to a temperature sensor element located in the mixing zone. To regulate the two liquid flows, a rotary segment is placed between the hot and cold liquid inlet port. The segment is operated by a torque unit which is made from a permanent magnet and an electromagnet. It is controlled by the regulator unit. When the segment rotates, one inlet port cross section decreases whilst the other increases proportionally. Constant outlet temperature is obtained since the sensor data produces a comparison with a required datum temperature.

Title: Multi-layered wall condensation barrier - comprising materials absorbing condensation at low temperatures and releasing it when warmer
Inventor: FEIDNER ERICH DIPL ING
IPC: E04B1/62
Filed: 1974-03-15
Abstract: As a simple means of checking the formation of dew point formation inside the cross-section of multi-layered walls, esp. in residential buildings, where condensation can effect heat insulation and have harmful effects on hygiene and comfort, suitable building materials are fitted at the point of condensation formation to take up condensation which is deposited at low temperature, and release it again when heating takes place, thus preventing harmful dampening effects from penetrating the wall. Before installation the barrier layer may be joined to a moisture-checking heat-insulating layer. Plaster of Paris is a suitable material.

Title: Smoking chamber generator - has revolving raw material storage drum attached to distillation drum with external heating
Inventor: SCHILLING GERHARD ING GRAD
IPC: A23B4/052
Filed: 1974-05-18
Abstract: A smoke generator for the prodn. of smoke from sawdust or wood shavings for smoking chambers consists of a rotatable storage drum for the raw material with helical paddles inside, and a distilling drum of smaller dia. which is attached to its side and rotates with it around a horizontal axis. The distilling drum is externally heated by heating elements and discharges the residue at its open end. The thermostat control of the heating elements prevents any partial combustion of the raw materials which liberates noxious substances. The condition of the raw material does not affect the transport or the feed proportioning of it.

Title: Protective circuit for automatic equipment disconnection - is from a battery when discharge current exceeds a permissible maximum
Inventor: AST JAKOB
IPC: H02J7/00
Filed: 1974-09-16
Abstract: The battery can be a storage battery, esp. a small size one. When the equipment switch (5) is operated, a capacitor (7) connected to earth is charged, even if the negative connection is still broken by a switch (6), thus closing the circuit of a relay coil (4), through which at least one contact to the equipment input and output stage is made, so long as the equipment is connected. The circuit is automatically broken when the battery (8) voltage drops below the normal discharge value, this being too low to hold the relay.

Title: Combined cupola furnace and gas turbine process - has waste heat from furnace used to preheat turbine combustion air
Inventor: STRACH LOTHAR
IPC: F02C7/08
Filed: 1974-10-22
Abstract: The invention proposes that the waste gases from a cupola furnace should be utilised to pre heat the gas turbine combustion air after the air has left the compressor and before entering the combustion chamber. A temperature of 400 deg.C - 950 deg.C should be achieved whereby the fuel consumption would be reduced and produce an exhaust with an oxygen surplus content of 400 deg.C, part of which could be used to complete the cupola furnace waste gas combustion, thereby increasing the heat offer to the turbine. The remaining part of the gas turbine heat could be used as a separate hot air producer without the need of a recuperator. The mechanical or electrical energy produced by the turbine is used in the foundry.
