Title: Method of producing slitting or parting cutters, in particular for the production of wood wool
Inventor: BARKE HEINER DIPL KFM
IPC: B23P15/40
Filed: 1983-01-04
Abstract: In order to simplify a method of producing four-tip slitting cutters, in particular for the production of wood wool, the slitting cutters being made from endless strip steel, and thus to substantially reduce the cost of the slitting cutters, it is proposed that at least one cutting edge be rolled on the endless strip steel, that the strip steel provided with cutting edges be notched in the transverse direction, the notching also extending over the area of the rolled-on cutting edges, that the bores necessary for threading together the slitting cutters be punched into the strip steel, that the strip steel be rounded and extended at the preliminary notched points, that the slitting cutters be cut to length from the endless strip steel and that they be cut off by squeezing, and that during the squeezing operation a bevel be made on the two narrow sides of the slitting cutters separated from one another.

Filed: 1983-01-13
Abstract: In a filter unit, in particular a liquid filter for a marine engine, in order to prevent the fastening screws (8) of filter casing (1) and filter lid (2) from being released as long as the filter unit is still under pressure, a safety means dependent upon the operating pressure is provided. Access to the fastening screws (8) is blocked by a pin (25) in such a way that a spanner cannot be applied above a certain pressure in the interior (13) of the filter unit. <IMAGE>
Patent DE-3302160-A1 (DE)
Inventor: PFEIFFER PETER
IPC: B05B11/00
Filed: 1983-01-22
Abstract: A dosing mechanism in the form of a manually operable, single-acting piston pump, which dispenses a given quantity of a substance, e.g. in atomized form, during each actuating stroke has a counter. For this purpose, a counting ring mounted in rotary manner on a base part is provided, which is advanced by one step per actuating stroke by an indexing device with cooperating and correspondingly bevelled ribs, so that in each case a different character in the counting ring appears at a window in the actuating pusher casing. Two projections cooperating with one another in a given position of the counting ring form a locking device against further actuation of the atomizing pump, when a given number of strokes have been performed.

Title: Process for the economic disposal of scum in sewage treatment plants
Inventor: BORST ADOLF H
IPC: C02F11/12
Filed: 1983-03-03
Abstract: In sewage treatment plants, in the region of the sewage feed in the first zone, namely the so-called sand trap, in addition to the settling bottom sludge, scum is also formed. This scum is conventionally introduced into the digestion tower or thickener together with the bottom sludge, and forms there in turn a floating layer with corresponding disadvantages. The introduction of scum into a separate mixing unit, arranged downstream of the thickener, where certain chemicals are added to the sewage sludge for dewatering, is equally problematic, since the large-size fractions get stuck in the mixer and cause operating faults. There is still no suitable method up to now of feeding the scum produced in sewage treatment plants to the thickening or dewatering process in a suitable manner. The present invention provides that the scum is metered directly into the secondary thickener of the sewage treatment plant in an appropriate manner and that the proportional and necessary amount of chemicals, equivalent to these amounts of scum, is added as a correspondingly increased chemical proportion to the mixing unit situated upstream of the secondary thickener and to the remaining sewage sludge for dewatering.

Title: Coupling for the angle-preserving coupling of two revolving parts exhibiting a large offset
Inventor: HAARMANN WALTER DIPL ING
IPC: F16D3/04
Filed: 1983-10-19
Abstract: A description is given of a coupling for the angle-preserving coupling of two parts revolving about parallel axes of revolution and exhibiting a large offset, in which two coupling halves are connected via a parallel-link mechanism having cranked, relatively long links. Compensating means are provided, by means of which deviations in the offset due to the length of the links of the parallel-link mechanism can be compensated. In one embodiment, one coupling half is constructed of two parts which, for their part, are connected to one another by a parallel-link mechanism with short links rotating past one another in one plane. Other embodiments bring about the compensation by changing the length of the cranked links.

Title: Discharge printing process for dyed polyester fibres
Inventor: GAREIS GUNTHER
IPC: D06P5/15
Filed: 1983-12-24
Abstract: To achieve lighter pattern effects on a deeper colour ground, aqueous printing pastes are applied to textile webs of polyester fibres which have been predyed with dischargeable disperse dyes as is customary which contain a combination of alkali, carrier and dye solubiliser as discharge agent, after which the material treated in this way is subjected to a steam process under HT conditions. According to the process, polyester fibres dyed in this manner can be discharged to white or, if discharge-resistant disperse dyes are additionally used, discharged to coloured.

Title: Permanent-magnet floating-piston motor for using the energy of permanent-magnet force, having smoothing of irregularly occurring rotation energy
Inventor: HORVATH SANDOR
IPC: H02K49/10
Filed: 1984-03-08
Abstract: In order to smooth the irregularly occurring rotation energy of a screw or propeller shaft which is driven by the wind, water flow or solar energy with changing cloud cover, and for transmission to an output shaft which rotates smoothly and is stabilised by a flywheel, the invention proposes that the energy which is incident at the input of the device be picked off in a pulsed manner and be transmitted in a smoothed manner to a permanent-magnet motor, the output shaft being directly connected only to the magnetic motor and being provided with a crank drive, and its respective position being used to determine when an energy pulse is to be picked off and passed on. This ensures that the energy pulses at the crank drive of the output shaft are used in an optimum manner and support the connecting rod in the movement which is already respectively taking place.

Title: Collapsible transport container
Inventor: DAHMEN KARL
IPC: B65D6/20
Filed: 1984-04-07
Abstract: In a collapsible transport container, consisting of substantially panel-type components, for example made of metal or plastic, the articulated connection of the individual components generally consists of hinge strips whose attachment is time-consuming and costly and which, if damaged, are often no longer functional. In order to simplify and improve the articulated connection of the individual parts of a collapsible transport container, each joint consists of a covering of thermoplastic which adheres firmly to two components of the transport container to be connected to one another in an articulated manner and, at the transition point from one component to the other, forms a flexible bridge and is preferably injected in.

Patent DE-3438407-A1 (DE)
Title: Foldable walking-stick seat
Inventor: DOTZAUER LISA
IPC: A45B5/00
Filed: 1984-10-19
Abstract: In order to be able to use a walking stick as a seat as well, the seat of heart-shaped construction is mounted on the side of the stick. For this purpose, the narrow end is mounted pivotably in a hinge part fixed to the stick with spacing from the handle, while the support, mounted pivotably on the stick in the plane offset to said hinge part, is constructed to be engageable in the free, broader end of the seat. Both parts, that is to say the seat and the support, can thus be raised, mounted pivotably on the stick, in the same manner or can be mounted on the stick in such a way that they do not cause an obstruction when the stick is used as a walking aid. The necessary stability is achieved for the user of the stick on the one hand by his/her own feet and, on the other hand, due to the fact that the part of the walking stick projecting beyond the seat also serves as a back support. <IMAGE>
