Title: Phosphate recovery from waste waters - comprising flocculation, hydroxide sludge formation and reuse after passing through anion exchanger
Inventor: KAEUFFER CARL CLEMENS DIPL CHE
IPC: C02F1/52
Filed: 1976-05-08
Abstract: Parent Patent discloses a process for phosphate recovery from waste waters. Waste water is set to pH 4-9 with acid or alkali, and mixed with Fe- and/or Al salts and opt. flocculants. Hydroxide sludge is sepd. from pure water. Hydroxide sludge is then treated with acid or alkali in concns. such that only the hydroxides, but not the organic cpds., go into soln. Hydroxide soln. is then added to the crude water. In present Patent of Addn. the hydroxide soln. passes through a phosphate ion-bonding anion exchanger before its re-use, thereby keeping pH below hydroxide pptn. level. Phosphate enrichment is prevented. Phosphate can be removed in a usable form, e.g. as Ca phosphate for use as fertiliser.

Title: Sluice gate with for river water - has float valve which raises gate when water level exceeds given level
Inventor: REPPERT HERBERT
IPC: E02B7/20
Filed: 1976-08-04
Abstract: The sluice gate comprises a tank (6) secured to the upstream side of the gate and having at its bottom an outlet (4) to the downstream side of the gate.

Title: Automatic plant watering system - with vacuum maintained in water feed channel corresponding to plant suction pressure
Inventor: GILEAD GIDEON
IPC: A01G27/00
Filed: 1977-01-26
Abstract: The watering procedure uses a feed channel which has outlets close to the plant roots. A vacuum is maintained in the water feed channel and this corresponds to the suction pressure of the plants during the desired watering. The water outlet is sealed against air entry into the water feed channel by a seal, especially a liquid seal. A temporary pressure which is higher than the operating pressure is set up in the water feed channel so that a fluid film is produced to seal the water outlet. The vacuum in the water feed channel is varied according to the water demand which varies with plant growth and this variation is automatically programmed.

Title: Release mechanism for normally engaged brake - has ratchet compensating for brake wear by allowing control rod to return under spring pressure (NL 31.5.78)
Inventor: MINNS GEORGE ERIC
IPC: F16D65/74
Filed: 1977-11-26
Abstract: The normally engaged brake has two external shoes (4, 5) urged against a drum (6) by a pair of spring-pressed levers (2, 3). A brake release mechanism has a rod (18) by which the levers can be pushed apart. The rod is pivoted to one (2), and freely projects through the other (3) lever. To release the brake the projecting end is urged against the other lever by a mechanical ratchet (19) supported on the latter. When not operated, the ratchet leaves the rod free to take up a position determined by brake wear. The opening movement of the ratchet is therefore independent of brake wear. The ratchet may be hydraulic.

The printing unit utilizes the masters to print on one side of a sheet of material as it passes through a printing nip. During a printing operation, blank sheets are sequentially fed from a supply pile through the printing nip and the first master is utilized to print images on first or front sides of the sheets.
