Title: Waste paper processing - using container to breakdown material by heat and pressure followed by dilution and sorting in rotating drum with perforated mantle
Inventor: MUSSELMANN WALTER
IPC: D21B1/34
Filed: 1993-03-05
Abstract: To break down used paper material, with a consistency of 8-15%, it is processed in a closed vessel together with gas or steam to give an overpressure of 0.2-4.0 bar and a temp. of 90-150 deg.C followed by dilution to a consistency of 3-5%. The material is sorted by rotation in a drum, pref. on a horizontal axis, with a perforated mantle, where the material is blown in through one end side. Appts. includes a container (1) with a feed opening for the used paper material which is covered by a lid (4) in a steam-sealed fit. A rotor (2) is at or near the base of the container to break down the material. At least one steam or gas feed (21) is connected to the container (1). The perforated mantle of the sorting drum pref. has openings of 6-20 mm and pref. 6-8 mm. The drum, with a reversing drive and interior bars to advance the material through it, is initially rotated for 3-5 mins. to carry the charge from the feed end as far as the closed end of the drum. For the remainder of the process time, up to max. 30 mins., the drum rotation is reversed to move the material axially back to the feed end for the heavy and large impurities and other large debris to be removed. USE/ADVANTAGE - The method is for breaking down used paper, for recycling, using heat and pressure. The operation gives an effective break-down and sorting of the material in a reliable and simple process, with cost savings.

Title: Method for making a thread connection by splicing
Inventor: HAASEN ROLF
IPC: B65H69/06
Filed: 1993-05-06
Abstract: The invention relates to such a method in which, in the course of a thread-connecting cycle, the drive device of the thread-connecting device executes a closed movement run-off of the time-coupled sequence. The object is to develop further such a method, so that the effectiveness of the splicing as a whole is increased. This object is achieved, according to the invention, in that the release of the splicing air is suppressed if the conditions necessary for a successful splicing operation are not present within the time-coupled sequence at the moment of release of the splicing air. These conditions can be the feed of the thread end located on the run-off bobbin side or run-on bobbin side, the presence of the necessary splicing pressure or of the necessary splicing temperature at a thermal splicer. In addition to the air used directly for splicing, under the conditions mentioned the opening air necessary for preparing the thread ends can also be suppressed. <IMAGE>

Title: Remnant shredder
Inventor: DIEMER BODO
IPC: B02C18/02
Filed: 1993-05-15
Abstract: The remnant shredder has a feed point for the remnants to be shredded as well as movable paring knives and a counterknife fixed to the machine. It cooperates with the paring knives during the shredding operation. Such remnant shredders are unsuitable for use in handicraft businesses and in small woodworking businesses. In order to allow an optimum comminution of remnants along with low initial costs, low electrical connected loads and low noise emission, the paring knives are provided on at least one knife carrier which is movable to and fro and above which the paring knives project. Only very low drive forces are required for this knife carrier. The remnant shredder is excellent for small businesses and handicraft businesses.

Patent DE-4317578-A1 (DE)
IPC: C22B13/02
Filed: 1993-05-27
Abstract: The working-up of zinc- and lead-bearing metallurgical plant residues is carried out by thermal treatment in a circulating fluidised bed, the heat requirement being met by combustion of solid carbon in the fluidised-bed reactor of the circulating fluidised bed. The solid carbon content in the lower part of the fluidised bed is adjusted to 5 to 30%. Oxygen-containing gases are introduced into the upper part of the fluidised-bed reactor, and the formation of CO2 is taken only so far that metallic zinc is not reoxidised. The discharged suspension is largely freed of solids in a return cyclone, and the solids are recycled. The gas is cooled to a temperature at which the metallic zinc is oxidised to ZnO, and the zinc and lead compounds in the form of dust are precipitated from the gas. <IMAGE>

Title: Throttle housing for internal combustion engines
Inventor: KOCHS MICHAEL DR
IPC: F02D9/10
Filed: 1993-07-10
Abstract: In the said throttle housing considerable leakages occur when the throttle valve is closed and low intake pressure prevails downstream of the throttle valve. In contrast to this the new arrangement has the characteristic feature that the throttle valve (11) is manufactured in a closed position in the body (2) with the throttle valve shaft (4) injection-moulded, the wall (9) of the intake port section (3) in which the throttle valve (11) is arranged forming the shell (9) of an injection mould (10), the end faces (7, 8) of which are formed by injection-moulding machine force moulds (5, 6) projecting into the intake port section (3) on both sides of the throttle valve shaft (4), which force moulds, if necessary, have injection and vent passages (12, 13). The expensive throttle valve assembly is dispensed with. Minimal leakages are achieved with the throttle valve (11) closed. <IMAGE>

Title: Hand-guided cutting tool
Inventor: LENKAT UDO
IPC: B26B5/00
Filed: 1993-09-17
Abstract: A hand-guided cutting tool, for example a trimming knife for plastic parts having a replaceable blade (3) is to be capable of being produced in a cost effective fashion. Furthermore, it is to be possible to exchange the replacement blade very rapidly. According to the invention, the guide groove (6), accommodating the replaceable blade (3) is rectangular in cross section. The base of the groove extends parallel to and at a distance from the longitudinal edges of the groove. Into the lateral webs (7, 8) there is inserted a transverse pin (5) which forms an abutment for a clamping wedge (4) and a stop for an actuating limb (4b) of the clamping wedge (4), the inclined surface (4a) of which faces away from the replaceable blade (3). The inclined surface inclines downwards from the end face of the handle (2) in such a way that the replaceable blade (3) is released when the clamping wedge (4) is displaced in the direction of the point of the replaceable blade. The invention is especially well suited for cutting tools used in industry. <IMAGE>
