Title: Sea water desalination - using solar and wind energy for spraying preheated water and condensing saturated recirculating air
Inventor: MERZ HANS
IPC: C02F1/04
Filed: 1975-01-10
Abstract: In a desalination process, sea water is atomized by spraying it through nozzles in a room heated by solar energy. The cooling chamber is equipped with copper plate elements through which fresh sea water circulates to assist in the condensation of the circulated water vapour. Blowers result in an intensified air circulation; the power for them and for the water circulation is supplied by wind-driven generators.

Title: Thermal power rotary engine - mixes vapourised fluid with heavy substance injects it onto turbine running wheels
Inventor: VEESER HEINRICH
IPC: F01K27/00
Filed: 1975-02-22
Abstract: Thermal power machine, in which vaporising system (1) vapourises a fluid (2) which becomes vapour easily. The resultant vapour is mixed in the manner of a sand-blast unit with a heavy substance such as lead, and conducted on to one or more turbine running wheels (4). This enables a utilisation effect of 60 to 80% to be achieved, but can be further increased by conducting the condensed fluid to a gasifier motor which at the same time has a utilisation effect of approx. 27% so that this combination produces an overall effect of some 95%. Exhaust gases and heat are conducted to a vaporising plant, so that there is no heat loss. The heavy substance, such as lead, mentioned can be delivered via a feed medium to the injection nozzle.

Patent DE-2522342-A1 (DE)
Title: Compact colour television camera - uses plumbicon tube for green and photodiode matrixes for red and blue components
Inventor: LINS JUERGEN DIPL ING
IPC: H04N9/04
Filed: 1975-05-20
Abstract: The colour television camera consists of an object lens (o) with the usual colour-splitter arrangement which separates the received light into red, green and blue components (FA). The green component is passed to the light-sensitive screen of a picture tube e g. Plumbicon. The other two colour components produce electrical analogue signals by means of photodiode matrixes (CCD1) (CCD2). The respective signals are processed in colour matrix circuits to produce the luminance signal and colour-difference signals. The use of the picture tube sensitivity to green to provide the luminance value leads to a higher quality picture than is conventionally obtained. Since the light-sensitive matrixes can be made very small by employing charge- coupled devices constructed in the form of integrated circuits and since the picture tube target area need only be the same size as the matrixes, a colour television camera of very small dimensions can be achieved.

Title: Indoor or outdoor heat preserving swimming pool cover - is made of rigid insulating material lowered by central spindle
Inventor: HEMMING BERNHARD DIPL ING
IPC: E04H4/10
Filed: 1975-07-26
Abstract: The pool-sealing cover for swiming-pools, for open air or indoor use, is a rigid lid-type cover of material with a good heat-insulating capacity which can be lowered from above onto the surface of the pool. This is operated, mechanically or manually, by a central spindle shaft. In the case of indoor pools the shaft is attached to the ceiling, while out of doors the raising and lowering process is effected with the aid of telescopic uprights. Asymmetrical pool surfaces and entry spaces can be covered. A high degree of accident prevention security is provided, and unintentional lowering is checked by locking latches. The cover will bear the weight of peoples, making it possible to use the room or space for other purposes when the pool is not in use. The cover can be subsequently fitted to existing pools, with no structural alterations involved.

Title: Horizontal force component prodn. for vibrating sieve - use two unbalanced motor one switchable to freewheel to change vibration vector
Inventor: HANEMANN SIEGFRIED DIPL ING
IPC: B06B1/16
Filed: 1975-11-15
Abstract: A vibrating sieve is driven by a pair of electric motors (1) (2) with parallel shafts rotating in opposite directions (5) (6) and with eccentric weights (3) (4). Such motors are normally synchronised so that resultant out-of-balance force acts only in the vertical direction. If the motor (2) is switched off, it continues to run under no-load conditions but with a phase lag (7) relative to the powered motor (1). This changes the direction of the resultant force providing a small horizontal component which is useful for freeing a blocked sieve. The speed of the drive falls by about 1% to 2% and the power of the driving motor increases by 5%.
Patent DE-2556255-A1 (DE)
Title: Circuit for calling one of several terminals - has number of lines reduced by grouping and using diodes

Filed: 1975-12-13
Abstract: The call circuit allows any one of several terminals to be called by depressing a call button and is for use in blocks of flats or offices. Each call button (e.g. 12) is assigned to one terminal and is connected at one end to a common rail and at the other over a first diode to a first common rail common to a first group of terminal and over a second diode to a second common rail common to a second group of terminals. There are several first and second groups, each terminal being connected into both groups. The advantage lies in reducing the number of lines leading to the terminals.

Title: Vibratory drive with centrifugal weights - has automatic locking achieved by off centre positioning
Inventor: WALTHER CARL KURT
IPC: B06B1/16
Filed: 1975-12-19
Abstract: The vibratory drives, especially those of vibratory grain containers are fitted with centrifugal weights which can be braced in position by a head plate associated with a cross-bar mounted to swivel transversely to the drive shaft wherein the operating handle arm opposite the tension face of the cross-bar can be securely locked in the tensed position if the tension faces of the cross-bar exceeds a dead centre position T-T. A resilient splay element (43) which can consist of an annular cusion or buffer is mounted between the two centrifugal weights. The reaction force from the weights acts in the locking direction of the cross-bar so that there is no danger its tension face can pass undesired into the release position.

Title: Coin processing system for vending machines - permits coins to roll in coin tester and reach horizontal transport system at coin tester lower end
IPC: G07D9/04
Filed: 1976-03-12
Abstract: Received coins fall or roll at an acute angle in a coin tester and reach a horizontal transport system at the coin testing channel lower end. The transport system carries coins through mechanical, electrical and/or electronic test units, so that they fall in a corresponding compartment. They are then conveyed through vertical screw conveyors to an intermediate store consisting of tubes. Tube content is counted, and when the required value is reached, the screw conveyor motor is reversed, and money is transferred from the screw conveyor to a cash box. The horizontal transfer mechanism comprises basically a chain with grab levers set around two sprocket wheels permitting safe entry of the coins into the system.

Title: Plastics moulded drawer with inner and outer guides - has profiled guide section providing reinforcement against bending stresses
IPC: A47B88/12
Filed: 1976-05-06
Abstract: The plastics moulded drawer is provided with a roof-shaped guide section along the upper third of the side wall for engagement in an outer guide, e.g. slide or roller guide. This roof-shape pref. includes an angle in the range of 90 deg. to 120 deg. The outer arm (5) projects downwardly relative to the side wall. The upper part (7) of the latter runs perpendicular above the apex of the guide section whilst the lower part (6) runs straight down to adjoin the inner arm (4). Any bending forces acting on the side walls are partly taken up by the guide section and partly transferred to the outer guide so that the positive engagement between the guide section and outer guide is the stronger the greater the load on the drawer.
