Title: Settling tank esp. for dirty water from sugar prodn. - has feed pipe above ground for easy maintenance
Inventor: BRUNKE HEINZ
IPC: B01D21/24
Filed: 1977-02-18
Abstract: A purification plant, esp. for flotation water from a sugar production plant, comprises a circular tank with central dirty water feed, annular channel around the perimeter for removing the overflowing clarified water, and annular trough at the bottom of the tank for sludge removal. A radial revolving bridge spans from the central tower to a roller support at the perimeter wall and carries sludge scrapers and also a sludge extration pump which dredges out the trough. The feed line for dirty water is stationarily mounted above the tank, and is connected to the central dirty water feed leading into the tank by one or more revolving intermediate collecting vessels, arranged to revolve about the central tower. The feed line for dirty water to the tank is above ground instead of being buried. At low throughput rates, therefore, there is no risk of a pipe below ground becoming clogged with settled sludge.
Patent DE-2710448-A1 (DE)
Inventor: FROEHLICH ECKHARD
IPC: B65H3/08
Filed: 1977-03-10
Abstract: To improve the operating reliability in a simple manner, a lifting device (1, 2) is provided which, as regards the energy supply, is separate from the suction device but carries the suction device. The pressure loss occurring in the suction channels (13, 15, 14, 9) or the suction lines on sucking in a sheet serves for controlling the drive of the lifting device (1, 2). Preferably the vacuum source, as a pneumatic energy source, is connected via a second suction line both to the suction line and to a directional-control valve. <IMAGE>

Title: Cylinder liner for piston engine - has internal surface indentations left after honing to improve oil distribution
Inventor: FRANKE GERHARD DR ING
IPC: F02F1/10
Filed: 1977-10-08
Abstract: The cylinder tubes for piston engines are lapped to produce the final internal surface finish. Before this production process, the internal surface of the cylinder tubes is subjected to a process which produces indentations on the surface which are not totally removed by the lapping operation. This indentations can be produced by using a vibrating cutting tool for the final turning, or the surface can be blasted with steel balls. It is also possible to apply chemical erosion on the internal tube surface. The indentations ensure adequate oil distribution on the cylinder wall.
Patent DE-2749707-A1 (DE)
Title: Alarm system for car accidents - automatically dials emergency number via car radio telephone and replays tape recorded emergency message
Inventor: LAUDIEN DIETER
IPC: G08B25/01
Filed: 1977-11-07
Abstract: The alarm system, for motor vehicle accidents, sends a recorded massage via the public radio communications network (car telephone network) when an accident occurs. The output of a tape recorder is connected to the telephone set's LF circuit, which is also connected to the output of a microphone's preamplifier. An alarm button (operated by the driver) disconnects the headset's loudspeaker and the microphone from the LF circuit, connects the microphone plus preamp. and the tape recorder's output to the LF circuit and switches on the tape recorder. The button also initiates the dialling of a preprogrammed emergency number to which the recorded emergency massage is replayed. The microphone which is now-sensitive picks up the noises of the accident within e.g. a radius of a few metres.

Title: Coin tester using electronic probe - selects mechanical sorter for predicted coin type and examines dimensions of coins
IPC: G07D5/00
Filed: 1978-04-03
Abstract: The coin testing appts. tests each coin testing appts. tests each coin electronically by means of a probe (4). The appropriate mechanical sorter103, 203, is then operated according to the type of coin detected by the probe. Subsequently a counter (110) is operated. Coins which fail the electronic test fall past a member which only moves into position to intercept or guide coins which have passed the electronic test. Timing stages delay the energisation of the selected mechanical sorter after the electronic test to allow time for a good coin to reach the mechanical sorter and a bad coin to pass by.

Title: Wheel rim with tyre retaining band - has normal well to permit tyre fitting and band in well with tightening system
Inventor: MATSUMIYA JAMES AKIRA
IPC: B60B21/12
Filed: 1978-09-28
Abstract: An obstructor element for a wheel rim has a bead receiving well in its base. The obstructor element is used for surrounding the whole of the periphery of the well, and consists of a band of which a major part, extending along a major portion of the periphery of the rim, is for positioning adjacent the mouth of the well. A minor part is an inset cranked portion, the inset portion including a floor part, the floor part being spaced radially inwardly from the remainder of the band-like element by a radial distance corresponding to the radial depth of the well. The floor part of the band-like element is for overlying a base of the well when the major part of the band-like element is adjacent the mouth of the well to prevent ingress of any tyre bead into the latter, the cranked portion of the band-like element being adapted to be positioned adjacent to a valve aperture in the well.

Title: Pin table amusement machine - is played with circular slide element which recoils actively on meeting an obstruction
Inventor: DOEBLER HANS J
IPC: A63F7/40
Filed: 1979-01-13
Abstract: The amusement machine uses circular slide elements (5) instead of balls. Each slide element contains a mechanism which causes it to recoil energetically, whenever it touches a post or the rim of the table. The posts and the table rim are provided with contact strips, connected to an electric power supply, at the same height as the contact discs (37, 38) on the slide element. One contact disc (38) is of larger diameter and is free to move radially, so that it is moved off centre when the slide element meets an obstruction. When both contact discs are in contact with the supply strips, the solenoid (26) is energized and its armature (34) is pulled down. The cone (31) on the armature recentres the disc, and this accelerates the slide element away from the obstruction.

Title: Electronic coin tester with oscillator feedback sensing coil - evaluates half-wave rectified input or output using threshold circuit controlling sorters
IPC: G07D5/08
Filed: 1979-04-19
Abstract: The electronic coin tester passes coins through an alternating magnetic field of an oscillator coil. The oscillation variations are analysed using threshold circuits controlling sorters and/or generating pulses. It has higher checking resolution and is cheaper to manufacture than its commercially available alternatives. The oscillator is a LC push-pull type with two complementary amplifiers. The oscillator feedback impedance inductivity varies with the effect of the coins. The oscillator is asymmetric and has different input and output capacitances. One amplifier is connected to the operating voltage via a resistor and the other to earth. The oscillator gain is dependent on the operating voltage. The high frequency oscillator input or output voltage is half-wave rectified and evaluated.
