Patent DE-2814183-A1 (DE)
Inventor: MENKE WILHELM
IPC: G07F17/34
Filed: 1978-04-01
Abstract: To increase the incentive to play and prevent the possibility of fraudulent manipulations, at least one of the play-feature carriers (4) is connected to a synchronous motor (15) for generating a running at approximately constant speed which is slow in comparison with the other play-feature carriers. The speed of this play-feature carrier (4) can be controlled via a computer. The time interval between the successively occurring positions (I to XX) of the loss and win symbols can be recorded by photoelectric scanning. This time interval between the individual positions can be compared with a specific desired timespan entered in the computer. At the moment of actuation of a stop button assigned to this play-feature carrier (4), the computer monitors the position state of this play-feature carrier (4) via the photoelectric scanning. The play-feature carrier (4) is provided with coded hole combinations (21) which are parallel to its axis and which belong in a specific number to a position (I to XX) of the play-feature carriers. The smallest hole (25) of the hole combination (21) belonging to a position is assigned a strobe bit. <IMAGE>

Title: Printed circuit board protected against tugging strain - has T=shaped slot in edge providing simple tension-relief for flat connection cable
Inventor: STRINGA HANS
IPC: H05K3/32
Filed: 1978-06-07
Abstract: The printed circuit board has a T-shaped slot (4) in one edge to provide strain protection for the flat flexible connection cable (3). The bared ends of the wires (31-34) projecting from the cable fit into contact holes (11-14) located in a row parallel to the T's crosspiece and just next to this crosspiece in body of the board. The cable is inserted into the slot's stem sideways and then turned to lie in the crosspiece. The wires are soldered into the holes. The advantage lies in simplicity, no extra components are needed for tension relief.

Title: Railway safety data transfer device - is used on sectioned track with associated fixed stations enabling speed dependent vehicle spacings
Inventor: FIEDLER JOERG ING GRAD
IPC: B61L3/22
Filed: 1978-07-12
Abstract: A railway safety device enables continuous signal transfer between the railway vehicles and a fixed station via a data channel carrying a uniform series of signals permitting telegraphic exchanges. The vehicles on the section of track associated with a station receive selective signals from it. the station receives data enabling determination of the control information.

Title: Ski brake made from U=shaped spring wire - has steep screw thread pivots to generate rotation under spring action when released
Inventor: UNGER PAUL
IPC: A63C7/10
Filed: 1978-08-30
Abstract: A ski-brake (10) consists of a piece of spring wire bent to a U shape with the arms (11) of the U diverging when the spring is in its free state. The brake (10) is fixed to the ski (1) by screws with a very steep angled thread (13). As the brake is swung down to its travelling position the arms (11) are pulled towards each other and lie parallel to the edge of the ski. When the ski is released from the ski-boot the spring force pushes the arms outwards and the steep angle of the thread (13) causes the brake to rotate and dig into the snow.

Title: Coded information transmission system - uses recurrent code with two correction syndromes and timing stage to provide signal at given interval after last detected signal
Inventor: MARKWITZ WERNHARD DIPL ING
IPC: H04L1/00
Filed: 1978-10-18
Abstract: The transmission system uses two syndromes (S1, S2) one of which is used to correct the information and the error signalling bits of the other syndromes (S2) used to reset a counter (21), so that a given count value is only achieved if no errors are indicated. A timing stage (ZST) provides a signal (ZS) at a given duration after the last detected error signalling bit of both syndromes. This duration is less than the least time required to obtain the given count value, and the signal (ZS) from the timing stage (ZST) is used to reset the counter (Z1). The timing stage (ZST) may use a second counter supplied with the same count pulses (T) as the first counter (Z1) and supplying the reset signal (ZS) for the latter when it reaches a second count value.

Title: Activated sludge aeration control - by adjustment to optimum dissolved oxygen concentration
Inventor: TANUMA RYOUHEI DIPL ING
IPC: C02F3/00
Filed: 1979-08-30
Abstract: A method for optimising the air input in an activated sludge mixt. in a sewage treatment plant is based on forming a function F.P2, where P is the difference of the partial oxygen pressures in the air entering the leaving the mixt., and F is the air input rate. The derivative of this function is used as the controlling figure for the optimum air input rate. The concentration of the dissolved oxygen is then just right to effect a 100% aerobic reaction, corresponding to approximately 0.4 ppm dissolved oxygen.

Title: Temp. compensating circuit for quartz crystal - applies discrete tuning volts to varactor diode at given temperature intervals
Inventor: FRANKE MANFRED
IPC: H03L1/02
Filed: 1979-09-08
Abstract: The compensating circuit compensates for frequency changes produced by changes in temp. at the quartz crystal (4) in the oscillator (3). A varactor diode (5) tunes the frequency of the crystal. The tuning voltage applied to the varactor does not change continuously with the temp. but in discrete steps at given temp. intervals. The tuning voltages are produced by a set of resistors (8-11) connected in parallel and forming one half of a voltage divider and connected to a selection switch (12). The selection switch connects each resistor to one supply pole and is controlled by the output of the temp. sensor (19). Alternatively, the tuning voltages may be produced by analog/digital and digital/analog converters.

Title: IC engine with external ignition - has high compression ratio and late ignition for constant pressure combustion
Inventor: RIEDEL HANS DIPL ING
IPC: F02B1/06
Filed: 1980-02-01
Abstract: An internal combustion engine with an external ignition source is operated to give combustion at constant pressure. A compression ratio of 16 to 1 or higher is used, depending on the fuel octane number, together with a very lean mixture with about 35% excess air. The limit is set by the need to avoid self-ignition at top dead centre. The ignition device is modified to suit the higher compression pressure and combustion velocity. Ignition at full load and speed is timed as near as possible to top dead centre while avoiding knocking, typically at about 15 deg. past top dead centre. More efficient combustion and pollution free running is obtained.

Title: Wire stand for steam iron - stows away under board top and permits angular support
Inventor: ESKILSSON HANS-AKE
IPC: D06F81/00
Filed: 1980-03-13
Abstract: A stand for a flat iron, especially one steam outlets in the sole plate, is a frame made of substantial metal wire and is attached to a plastic block underneath the ironing board at one end. The central wire is pushed in when the iron is not in use so that the whole strand disappears to below the board top. To use it, it is pulled out and turned through 180 degrees when a detent holds it. Bent-up wires hold the rear and the sides of the iron. To achieve the desirable 45 degrees side turn for a steam iron, another detent holds the stand at that angle. This stand can also be used by left-handed person who would then stand at the other side; the stand can also be turned 45 degrees towards that side.

Title: Metal chip crushing plant - has vibrating tippable screening and sorting hopper fitted before chip entry to rotary crusher
Inventor: ADOLPH MANFRED
IPC: B02C21/00
Filed: 1980-04-23
Abstract: The metal chip waste (31) is deposited in front of the feed end of the crusher and is periodically fed by a grab (29) travelling on an overhead rail (30). The grab (29) drops the waste into a hopper (12), hinged on one side to the machine frame, while the other side is resting by an extending bracket (18) on a set of springs (20). The bracket (18) is under the action of a vibrating device (19). The bottom (14) of the hopper (12) is perforated with holes allowing the finer fractions of the metal waste to pass through and drop through a chute (25) into the transport container (11). The vibrating movement of the hopper (12) removes larger particles through slot (a), chute (26) into container (27), from where they are removed for crushing.
