Title: Water drive rotary grill - operates using wheel onto which water pours from and into containers, made of U=shaped sections
Inventor: LITZLBECK GEORG
IPC: A47J37/07
Filed: 1980-05-22
Abstract: The rotary grill is driven round by a water wheel (7) which is fed by water running onto it from a container (2) over it. The water runs off the wheel (7) into a container (10) underneath, when it is used again. The water wheel (7) is formed of U-shaped sections which are cut at acute angles to each other and are inserted into each other to form segments of the wheel, and are supplemented to form enclosed containers.

Title: Quick release ring for vacuum pipe joint - has clamping bolt pivoting about axial stud in end lug, and has lever in plane of clamp
Inventor: LINNEMANN FRIEDRICH
IPC: F16L23/06
Filed: 1980-06-18
Abstract: The quick release clamp for V-flange joints of vacuum pipes consists of two identical half clamps (9,10), hinged together by a link (11). End lugs (14,15) are formed on the half clamps on the sides opposite to the link. These lugs have surfaces (18,19) which slope towards each other in the direction of the clamp centre line. The half clamps are joined by a bolt (23) which is pivoted directly to one half clamp. The other end of the bolt screws into a pin (29) with a transversely tapped hole. This pin forms a pivot for a locking lever (31) with a triangular head. One side of the head abuts against the sloping face (19) of one end lug (15). The clamp is released by swinging the locking lever outwards and pressing the two clamps together until a nose (38) of the triangular head clears the lug surface.

Title: Accurate semi-automatic fruit packaging and weighing machine - has wide and narrow vibrators with electronic controller
Inventor: LEON RODRIGUEZ RODA JUAN ANTON
IPC: G01G13/02
Filed: 1980-07-08
Abstract: The semi-automatic weighing device is used for fruit being packaged in given wt. units and enables the supply of fruit to be interrupted when the desired wt. is reached. The feed is automatically interrupted so that the desired wt. is not exceeded. The feeder contains two vibrating elements (2,3) of different widths between a hopper or distribution container (1). The balance contains an electronic control unit which deactivates the vibrating elements when the desired wt. is achieved. Alternatively, the wider vibrator is stopped when the wt. is well below the desired level. The narrower vibrator is stopped when the desired wt. is actually reached. The weighing balance pan can be manually tilted. A side wall opens and the fruit is discharged, thus beginning a new cycle.

Title: Boosting liq. jet cutting properties - using high energy laser beam, directed onto liq. jet for pulsing
Inventor: ODOZYNSKI RYSZARD JAN DR
IPC: B26F3/00
Filed: 1980-09-15
Abstract: High energy water jets are used both for material machining and for rock disintegration in mining etc. The water jet cutting characteristics are successfully boosted by pulsed interruption of a uniform and continuous water jet, emerging from a nozzle. In addition the water jet may be also modulated. This boosting is attained by directing a high-energy pulsed laser beam onto the water jet. Pref. the laser beam is directed orthogonally onto the water jet. The latter may be divided in individual segments. If the laser beam is concentrated inside the water jet, it is possible to produce cavitations. The system provides well controlled and pronounced modulation of the water jet.

Title: Method and device for automatically controlling an electro-erosive treatment process
Inventor: VASILIEV JURIJ VIKTOROVIC
IPC: B23H1/02
Filed: 1981-05-06
Abstract: A method for automatically controlling the electro-erosive treatment process consists of the electrical resistance of the spark gap being measured during additionally produced periodic pauses between the pulse group of a generator. The magnitude of the electrical resistance is determined from the voltage drop across the spark gap, which is a linear function of the resistance of this spark gap to be measured. This voltage drop is produced across the said spark gap only for the duration of the spark gap resistance measurement. The device intended for implementing this method contains a supply source (1), which is connected via a diode (2) to the electrodes (3, 4) which form the spark gap (5), and a clock pulse generator (6), which is electrically connected to a pulse generator (7) and to an electrical resistance sensor (9). The pulse generator (7) and the resistance sensor (9) are additionally connected to the electrodes (3, 4). The supply source (1) contains a transistor (10) and two voltage sources (11, 12). The outputs of one voltage source (11) are connected via the diode (2) and the base-collector junction of the transistor (10) to the electrodes (3 and 4). The outputs of the other voltage source (12) are connected to the base and to the emitter of the transistor (10), and its input is electrically connected to the clock pulse generator (6). <IMAGE>

Title: Package, in particular for use in the automatic packaging of a stack of coins
Inventor: PEDERSEN AGNER JESPER
IPC: B65D75/06
Filed: 1981-05-14
Abstract: A package, in particular for use in the automatic packaging of a stack of identical coins (9) so that a roll (6) of coins is produced, has a piece of web-like material (1) which is rolled around the stack of coins and whose edges are simultaneously folded over at the two ends of the stack of coins to form annular beads (7, 8). The web-like material (1) is provided with parallel lines of weakness (2, 3) formed in the longitudinal direction of the web and arranged symmetrically about the centre-line in the longitudinal direction of the web and with a mutual spacing primarily corresponding to the length of the stack of coins to be packaged. It is thus achieved that the package can easily be opened in that the central section (12) between the lines of weakness (2, 3) is unrolled and torn off while the remaining part of the package and the stack of coins rotate in the hand so that all the coins are released from the package simultaneously. <IMAGE>

Title: Typewriter
Inventor: HIMBERT JUERGEN
IPC: B41J13/036
Filed: 1981-05-23
Abstract: The invention relates to a typewriter which has a platen, a rotary drive and guides for guiding a sheet to be typed around the platen. Known typewriters have the disadvantage that the greatest possible width of a sheet is limited by the respective length of the platen. This limitation is removed in a typewriter designed according to the invention and characterised in that a tandem roller is provided parallel to the platen, in that the platen can be driven by the tandem roller synchronously and in the same direction of rotation, in that the sheet is guided in each case around part of the circumference of the tandem roller and of the platen, and in that the tandem roller can be driven by a drive roller which engages on the part of the sheet guided around the tandem roller. With this typewriter, a sheet of any desired width can thus be typed without the length of the platen having to be matched thereto. <IMAGE>

Title: Model for demonstrating the function of an eye, in particular the accommodation of the eye
Inventor: PFITZNER KLAUS
IPC: G09B23/32
Filed: 1981-11-20
Abstract: The invention relates to a model for demonstrating the function of an eye, in particular the accommodation of the eye. The model according to the invention is characterised by the provision as crystalline lens of a convex, preferably planoconvex, liquid lens, which is arranged in the beam path between an imaging object and a screen serving as substitute retina and whose curved boundary surface is a transparent elastic membrane skin. This yields the advantage that the refractive properties of the liquid bubble located in the liquid lens can be varied in the simplest way in order to represent the accommodation by varying the pressure of the liquid in the liquid lens, the elastic membrane skin being deformed.

Abstract: The invention proposes a solid state control and switching circuit for an automatic flue-gas register system, which contains two AC switches. The first switch is controlled by the thermostat and applies a control signal to the control terminals for the ignition of a gas furnace or oil burner. The second AC switch responds to the output signal of a timer which can be programmed as required and, after a programmable delay, passes a control signal to the register motor in order to close a flue-gas register flap which is fitted in the extraction chimney of the heating device.
