Patent DE-2421476-A1 (DE)
Title: Heat reactor for sterilisation processing of fluids - esp. of ferment culture media, sewage sludge, industrial effluents
Inventor: SASSA NAGAMASA
IPC: B01J19/00
Filed: 1974-04-30
Abstract: A heat reactor installation arranged at ground level, esp. for the sterilisation of excess sewage sludge, comprises a combination of >=1 sets of condensation heat exchangers with one or more sets of vaporising coolers. The sludge and water mixture circulates through a series of pumps and condensation heat exchangers of the suction or force-feed type, whilst its heat is raised in stages to 200 degrees C., and then through a battery of vaporisation coolers, heat being recovered by the direct contact of the vapour from each cooler being brought into contact with the fluid passing through the corresponding heat exchanger, until the mixture is cooled sufficiently for filtration.

Title: Lighter carrying lash freighter - consists of catamaran with lock chamber to load and unload lighters
Inventor: MATTHIES JUN BERNHARD
IPC: B63B35/42
Filed: 1974-05-27
Abstract: The freighter is formed as a conventional catamaran. The Floating bodies (1, 2) have ballast tanks (20) in the walls, and contain lock chambers (4), to load and unload lighters (7, 10). At least one of the lock chambers is positioned far inside the floating body, so that a lighter may be accommodated in front of the lock gate. The main deck extends over the complete width of the hull, and is divided into water-tight cargo holds (12), which may be connected to individual lock chambers. The arrangement allows the mother ship to take on or release smaller river or canal vessels for travel on open seas without the need for cargo transfer at normal land based ports.
Patent DE-2427056-A1 (DE)
Title: Flat roof of bonded chippings overlying impermeable membrane - has thin separating sheet between preventing chippings sticking to membrane
Inventor: KLAPFENBERGER FERDINAND
IPC: E04D7/00
Filed: 1974-06-05
Abstract: A method of making a flat roof comprising a thick layer of chippings overlying a watertight membrane of PVC sheets or the like which are welded together in situ on the roof, is as follows: after the watertight membrane has been laid, a relatively thin layer of easily torn matl., e.g. an 0.2 mm. thick polyethylene sheet is laid over this; the chippings are premixed with a binding agent which will harden later and which does not penetrate through or attack the thin sheet, and this chippings mixt. is then laid on this thin sheet and sets hard to form a plate-like structure. The thin 0.2 mm. thick polyethylene sheet thus acts as a sepg. sheet between the chippings layer and the underlaying PVC membrane. A prefd. method of laying the chippings and binding agent mixt. is to palce open frames of strip steel or the like in squares on the roof and pour the mixt. into them, removing these frames later. These frames pref. have the final depth required for the chippings layer.

The additional, parallel line pref. has less than 50% of the cross-sectional area of the main steam line. In a preferred embodiment there are two safety valves associated with the additional line, these two valves pref. responding at different levels. A shut-off valve may be incorporated upstream of each of them. These valves are so interlocked that when one of them opens, the other closes.

Title: Tubular-column-supported spiral staircase - with spacer rings as compensating pieces with peripheral grooves forming wedge stems
Inventor: BRAUCKMANN JOHANNES
IPC: E04F11/032
Filed: 1975-01-17
Abstract: The spiral staircase incorporates a tubular column, over which the cylindrical parts of a series of step elements, and spacer rings between the step elements, are inserted and then firmly clamped. The spacer rings are in the form of compensating pieces, which have peripheral grooves on the outside of their top and bottom edges, with depth increasing towards the edge, to form wedge-shaped edge stems. At the top and bottom edges of the step elements there are congruently fitting facets sloping from the inside. The internal diameter of the cylindrical part of the step elements pref. exceeds that of the compensating pieces, or the external diameter of the tubular column. Less precision is needed in manufacture, and step elements can be quickly and easily set in place.

Title: Switching system for thermoelectric switches - has bridge contact carrier resting in no-load position on bearing surface
Inventor: BAYER HELMUT DIPL ING
IPC: H01H37/54
Filed: 1975-02-28
Abstract: The switching system is intended for temperature regulating and limiting switches with bimetal snap-action discs. The system contains a switching head with moving contact(s) on a contact carrier, actuatable by a bolt in positive connection with the bimetal disc, the bolt being brought out from the switching head. A contact bridge forms the contact carrier, which in no-load condition rests with its both ends on a bearing, and on the other hand is affected by a force of a spring pressing it against the bearings. The bolt counteracts the spring force at the contact bridge. The point of engagement of the spring is located between the point of engagement of the bolt and one end of the contact bridge.

Title: Height adjustment for book binding machines - has handwheel operated adjustment spindle located within table support
Inventor: THIEME GUENTER
IPC: B65H31/18
Filed: 1975-04-14
Abstract: Height adjustment system for the machine tables of book binding machines, especially folding machines. There are table supports guided within the machine frame with an adjustment spindle located within the table support with a handwheel actuating the height adjustment.

Title: Electrically driven runner for curtain - has limit switches which are operated by adjustable stops to prevent overtravel of runner driving mechanism
Inventor: BLUEMLE MANFRED
IPC: A47H5/02
Filed: 1975-08-01
Abstract: The curtain (15) is supported by rollers (16) which run off the lower flanges of the support rail. The curtain is moved along the rail by the electrically driven runner (7). Over-travel of the runner is prevented by the limit switches (3)(4)(5)(6). These switches are normally closed but are opened on striking the adjustable stops (9) (10) at each end of the curtain support rail. To remove the curtain from the rail it is only necessary to remove the blocks (11)(12). The limit switch stops (9) and (10) are thus not disturbed so that the ordinary housewife is not faced with the problem of resetting the switches when she removes the curtain.

Title: Telescopic steering column with bearing races - has races fitting in cylindrical cage with guides onto shallow grooves cut in shafts
Inventor: SCHULLER WALTER
IPC: F16D3/06
Filed: 1975-09-10
Abstract: A telescopic steering column has bearing races which prevent the two telescoping shafts from turning relative to one another. The grooves for the ball bearings are in the outer face of the inner shaft and the inner face of the outer shaft. This reduces the weakening of the shafts at the point where the grooves are cut and simplifies assembly. The grooves (10, 7) are partly in a cylindrical cage (9), fitting between the shafts (1, 2) and partly cut into the shafts themselves. The cage can be made of a series of shells, each shell having a running path for its own ball race. Connectors fit along the edge of the shells and the shells can be made from plastics. The cylinder can be designed as a group of interlocking segments.
