Title: Revolving raking shield bridge support - on basin rim by rollers in separately adjustable bogies
IPC: B01D21/06
Filed: 1976-09-25
Abstract: A revolving bridge carrying a bottom raking shield for settling basins in sewage sedimentation systems rests at one end in the centre of the circular basin and at the free end on the basin rim by the rollers of the travelling gear, one of which is driven by a motor. Each roller is supported in a sepd. bogie so that the radius of their running track can be readily and steplessly adjusted. Inaccuracies in the construction of the basin cannot now lead to premature abrasive wear of the rollers and the bridge can be easily adapted to basins of different dia.

Title: Warp tension control - using adjustment wheel as torque converter to control warp negative tension
Inventor: BORISCH FRED
IPC: D03D49/08
Filed: 1976-11-10
Abstract: A weight is used to control the tension of the warp yarns in a loom, as they are drawn off the warping beam. On one side, the control weight has a drive connection to the warping beam through a wound holding mechanism, such as an adjustment wheel carrying a pulling medium. On the other side, a connected control motor opposing the wound wheel drives it by the same value as the warping beam drive. The system controls the warps' negative tension simply, giving a constant tension without monitoring.

Patent DE-2723425-A1 (DE)
Title: Aeration of effluent in a treatment basin - which includes a flotation device for inspection and maintenance
Inventor: FUJITA TETSUO
IPC: B01F3/04
Filed: 1977-05-24
Abstract: Effluent is aerated and the aerated effluent is circulated through a treatment tank. The aerating and circulating device consists of a propellor mounted on a vertical shaft driving the effluent upwards through the rotors and thence through a series of ducts which direct the flow upwards and outwards. On the suction of the propellor is a basket mounted on the same shaft which is connected to an air compressor. The air issuing from the basket is entrained in the upward flowing stream of effluent passes through the propellor blades where a certain proportion of the bubbles is broken into smaller bubbles and is then carried with the stream of effluent up into the treatment basis. At the surface, the coarser bubbles pass into the atmosphere, but the finer bubbles are carried back with the circulation of the effluent down the outer wall of the basin and back into the suction of the propellor. The entire appratus is attached to a flotation chamber so that it can be floated to the surface for inspection and maintenance purposes. Existing processes for aerating treatment basis consist either of surface agitators which entrain surface air by means of mechanical agitation, a process which is noisy inefficient and cannot operate when the surface is frozen or of air distribution systems immersed in the basin which are liable to blockage and are difficult to maintain. The above system overcomes the disadvantages of the traditional equipment.

Title: Milking machine pulsator damping system - uses hydraulic chambers or springs and throttling hole system for control membrane
Inventor: HAPPEL FRITZ
IPC: A01J5/12
Filed: 1977-08-26
Abstract: The chamber (1) divides into two parts (3, 4) by a thin membrane (11) and forming a milking machine pulsator, also incorporates a braking system for its reciprocating spindle (7). The membrane is enclosed inside a further membrane (2) filled with fluid, and divided into two liquid filled chambers (9, 10).

Title: Floating oil barrier on water - in tubular sheet wall with dividing seam, battens, buoyant panels and heavy strips
Inventor: FUELLING WERNER
IPC: E02B15/06
Filed: 1978-12-15
Abstract: A flexible protruding wall, borne on buoyant units and loaded with weights, forms the barrier to keep water surfaces clear of oil floating towards them. It is made of double-layered foil sheeting or textiles joined to form a tube. It has a lengthways seam dividing it into a wider upper tube-shaped part and lower narrower one. Transverse battens of stiff material and openings between these on one side, partition it into sections. Panel-shaped buoyant units are inserted in the wider part between the battens and openings, and heavy metal strips in the narrower part. This is effective on fast-flowing water, checking oil and preventing it from passing underneath.
Patent DE-2854601-A1 (DE)
Inventor: NISHIMURA SATOSHI
IPC: G10L21/04
Filed: 1978-12-18
Abstract: An analog sound signal the time axis of which is compressed is sampled responsive to a write clock signal and the sampled output is stored in an analog shift register having a given capacity, whereupon the stored signal is read out from the analog shift register responsive to a read clock signal the frequency of which is smaller than that of the write clock signal. The above described operation is alternately repeated, whereby the output signal read out from the analog shift register is compiled for sound synthesization. The synthesizing junction of the sound signal is controlled by a microcomputer. The microcomputer is adapted to evaluate the similarity of the data concerning the waveform at the trailing end portion of a preceding sound element stored in the random-access memory and the data concerning the waveform at the leading end portion of the succeeding sound element stored in the random-access memory. Evaluation of similarity of the waveforms is effected by evaluating a mean square error or a mutual correlation function of two sets of data. The shift amount of the leading end of the succeeding sound element to be joined to the trailing end portion of the preceding sound element is determined based upon the result of the evaluation, whereby a read circuit is controlled to correct the time axis of the succeeding sound element, thereby to achieve continuity of the waveform at the synthesizing junction of the preceding and succeeding sound elements.
Patent DE-2856590-A1 (DE)
Title: Punched magnetic tape for automatic text writing system - has identifying hole to locate position of required stop and functions with mechanical, optical or electronic marking
Inventor: SISTIG GEORG
IPC: G06K19/06
Filed: 1978-12-29
Abstract: An automatic typewriter system uses data storage on punched tape that is used with a specific identification hole to enable the tape to be stopped at a specific point. The system is partic. advantageous in the production of standard letters, with the facility providing an automatic stop for the insertion of an address. Standard five hole tape is used with the drive track (3) located between tracks 2 and 3. A large hole (4) that takes in two of the drive track holes may be inserted either manually or by machine to indicate the requirement for the tape to be stopped. An alternative version uses a slot inserted on the drive track and is of the same width and takes in two drive track holes. The technique may also be applied to magnetic tape.
Patent DE-2910533-A1 (DE)
Title: Water supply for car wash - has water recycling control and dirt removal
Inventor: WARNECKE OTTO
IPC: B60S3/00
Filed: 1979-03-17
Abstract: A wash facility for a passenger vehicle has a closed circuit supply with fresh water top up and soiled water vent. The water from the wash and rinse stations (1, 2) is collected in a sump (4) where dirt etc. settle and are separated. The sump is periodically pumped out via a vent discharge (32). Cleaner water is recycled by pumping to a preparation chamber (7) from where it is passed to a supply chamber (14) or a mixing chamber for the wash facility. A sensor (17) in the sump determines if the water is clean enough for treatment for recycling or is to be dumped. The sensor is coupled to a processor which also controls the treatment and top up facility.
Patent DE-2913865-A1 (DE)
Title: Crankshaft in IC engines, esp. for motor vehicles - where journals and fillets are surface hardened, and then middle zone of journals is tempered to permit inexpensive straightening of shaft
Inventor: HORA PAVEL DIPL ING
IPC: B23P15/00
Filed: 1979-04-06
Abstract: Crank pins and journals plus their fillets are hardened, and then the middle zone of each pin is tempered for local redn. of the hardness. The crankshaft is pref. made of unalloyed C steel, which is hardened and then induction tempered in zones, followed by straightening so permanent deformation only occurs in zones. Straightening is pref. carried out via a press; cold or warm roll straightened; or during the induction tempering operation. Oil holes are pref. drilled in the crankshaft after tempering to avoid hardening cracks. When crankshafts are hardened in their fillets, simple straightening is normally impossible and expensive grinding operations are required. Invention eliminates such operations so inexpensive mass prodn. is achieved.
