Title: Sulphur recovery from relatively conc. sulphur di:oxide gas - by redn. to sulphur vapour and hydrogen sulphide in conjunction with water gas reaction
Inventor: WATANABE TERUO
IPC: C01B17/04
Filed: 1980-07-31
Abstract: In the recovery of S, a hot gas (I) contg. steam and O2 and a relatively highly conc. SO2 gas (II) are introduced into the lower pt. of a bed of carboniferous particles flowing downwards, so that pt. of the SO2 is reduced to S vapour and pt. to H2S. The gas stream contg. SO2, S vapour and H2S discharged at the top is freed from dust, then the S vapour is condensed. The gas is then mixed with (II) and introduced into a reactor contg. a Claus catalyst to produce S vapour, which is sepd. by condensn. Combination of SO2 redn. with the water gas reaction leads to a higher yield than usual.

Title: Oil lubrication system, in particular for knitting machines
Inventor: KUEHN FALK
IPC: D04B35/28
Filed: 1981-03-09
Abstract: The main application claims an oil lubrication system, in particular for knitting machines, having piston pumps (1), one of which is assigned to each individual lubrication point, and which have a pot-shaped electromagnet with a disc-shaped armature for the drive and which receive excitation current pulses (11) of adjustable pulse frequency from an electronic circuit arrangement (10). To increase the operational safety, according to the proposal of the additional patent application, a scanning device (7) is arranged on each piston pump (1) and produces an acknowledgement pulse (8) during the operating stroke when the pump piston reaches its end position. A monitoring device (14) is provided which recognises the occurence of an acknowledgement pulse (8) within a given time after each current pulse (11) and, if there is no acknowledgement pulse (8) transmits an interference signal (15). In this case, a display lamp (16) which flashes with each current pulse (11) switches to a continuous signal. The oil supply container (3) feeding the pumps can be provided with a filling level monitor (21) whose electric low-oil signal (22) together with the interference signal (15) are passed to a switching-off unit (18) which switches the machine off. <IMAGE>

Inventor: SATO YOSHIRO
IPC: H03B29/00
Filed: 1981-03-12
Abstract: In the present invention, a simulated noise signal is injected into the mains supply line of a device under test with no ensuing loss of AC power. This is possible through the use of a series resonant circuit (4, 5) whose resonant frequency is the same as the mains frequency. The series resonant circuit (4, 5) is placed within the mains supply line (I2) in parallel with the device (3), while an additional capacitor (6) is provided which is disposed in parallel with the mains voltage source (1). The simulated noise signal is injected at both ends of the series resonant circuit (4, 5), the occurrence of a power loss being prevented by the provision of the series resonant circuit (4, 5) concerned. A switch element (7) can also be provided in order to effect a short circuit of the series resonant circuit (4, 5) when a noise signal simulation is not used. <IMAGE>

Title: Door hinge for furniture doors or the like
Inventor: GRASS SEN ALFRED
IPC: E05D7/04
Filed: 1981-04-10
Abstract: The invention relates to a door hinge for furniture doors. The object of the invention is to develop a door hinge in such a way that the lateral adjustment allows a wider range of adjustment and takes place independently of the vertical adjustment and the correction can be made quickly. The object is achieved in that there are present between the screw-on plate and the body-frame end face means which, for the lateral adjustment of the furniture door, make it possible to vary the spacing, parallel in a horizontal and vertical plane, between the furniture-frame end face and the inner face of the screw-on plate, whilst maintaining parallelism. The essential feature of the invention is, therefore, that there is proposed a half-concealed single-jointed hinge, if appropriate with an integrated closing-pressure device, which is designed with separately adjustable vertical and lateral adjustment.

Patent DE-3200090-A1 (DE)
Title: Vacuum cleaner
Inventor: DIEBOLD MAX
IPC: A47L7/00
Filed: 1982-01-05
Abstract: In vacuum cleaners with a filter (5) projecting into the dust container (1), in the case of wet suction cleaning there is a higher level of liquid in the interior (6) of the filter than in the dust container (1) as a result of pressure differences. Consequently, its volume cannot be fully utilised during wet suction cleaning. In order to obtain a constant level of liquid in the entire device, a pressure compensation line (12) is provided between the interior (6) of the filter and the dust container (1), which pressure compensation line can be closed by a valve (13) which can be opened during dry suction cleaning. <IMAGE>

Title: Dual microphone probe for head-related stereophony (ear stereo microphone)
Inventor: DIESING HANS-WOLFGANG
IPC: H04R5/027
Filed: 1982-02-03
Abstract: Artificial-head stereophony provides audio recordings which convey three-dimensional sound patterns when reproduced via headphones. The natural quality of the sound reproduction puts into question the conventional criteria for faithful reproduction. One's own head is even more suitable than an artificial head as carrier for the two microphone capsules. It is only recently that electret capsules have become available which are small enough to be attached directly with ear clips at the optimum location in front of the entrance to the auditory canal without impeding the sound field of the outer ear. Attachment by clips to the ear lobes ensures excellent decoupling of the directly transmitted sound which can occur due to jolting and impact on the feed line. A much improved phantom feed which automatically switches itself on when the two jack plugs are inserted prevents switching-on from being forgotten before the beginning of the recording and the battery from being unnecessarily discharged afterwards. In addition, it also brings the microphone within the means of amateurs and it can be carried easily and inconspicuously. This is of particular importance for recordings with stereo cassette recorders in pocket format.
Patent DE-3204423-A1 (DE)
Title: Electrical stepping switch
Inventor: ILG WALTER
IPC: H01H3/46
Filed: 1982-02-09
Abstract: The invention relates to an electrical stepping switch having a moving contact part, a push rod and an operating handle, the push rod being pivoted on the moving contact part and on the operating handle, and the pivoting taking place at one end via an adjustment device. It is intended to create a stepping switch of this type which can be adjusted simply and reliably with little manufacturing complexity, so that exact switch positions of the moving contact part correspond to the various positions of the operating handle. This object is achieved in that an adjustment device which is arranged either on the moving contact part or on the operating handle has a pivoting lever which is joined to the moving contact part or to the operating handle such that it can pivot and has a hinge point for the push rod which is remote from its hinge point, and whose free end is movable for example in the movement direction of the contact part or of the operating handle and relative thereto, and the moving contact part or the operating handle and the pivoting lever have latching devices with a plurality of latching positions for latching in different positions relative to one another. <IMAGE>

IPC: B65G47/90
Filed: 1982-03-23
Abstract: method and device for transferring dough pieces of different weights and volumes from kneading plates of different structural form and kneading-trough number onto ancillary set-down surfaces/fermentation supports or onto conveyor belts of rolling-out, folding and long-kneading devices without and with automatic set-down on fermentation supports in an arrangement appropriate for baking. The device hangs on a bracket above the receiving conveyor belt of the further-processing device or is moved away automatically on a slide via a static set-down surface, if the dough pieces are to be set down in a manner suitable for baking without further deformation. A kneading plate filled with dough pieces is introduced into the device and the dough pieces are removed therefrom by two alternately active grippers/suckers and transferred to an integrated conveyor or accumulator belt which forwards the dough pieces individually or in rows for processing. Manual removal of the dough pieces from the kneading plate is thus rendered superfluous.
