Title: Ring for fixing max. load plate to lifting gear - has pivoted ring halves with mutually engaging snap-in tongue and groove ends
Inventor: WALTERMANN HUBERT
IPC: F16B45/02
Filed: 1980-05-12
Abstract: The ring is intended for permanent securing a maximum load and/or parameter plate or the like to lifting gear. It comprises two part-annular portions (1,2) having one end (3,4) connected via a pivot (5) parallel to the ring axis, whilst their other ends (6,10) form a tongue (7) and groove (13) respectively, which align these ends (6,10) relative to each other on engagement. These ends are further shaped to form a snap-in coupling (7-9-11) whilst at least one end has a tapering portion (12) which, on mutual engagement, causes the ring portions to be tensioned against their resilient spring action.

Title: Electrode for intermittent welding, esp. spot welding of aluminium - is made of material such as silver so that unsightly marks are not left on workpieces
Inventor: MENGELBERG HANS-DIETER DR
IPC: B23K35/22
Filed: 1980-06-26
Abstract: The electrode is used for the welding of material which is a good conductor of electricity, e.g. Al. The material of which the electrode is made forms reaction prods. with the workpiece; and the reaction prods. are easily removed by light mechanical action, e.g. wiping or rinsing, after pickling. The electrode is made e.g. of silver, which is dispersion hardened; reinforced by fibres; or hardened by finely dispersed powder consisting of Al2O3, BeO, SiO2, SnO2, or similar powder. Useful as a replacement of copper electrodes which form black marks on the workpieces being welded. Such black marks are very difficult to remove.

Title: Tablet consisting of porous, fibrous carrier - and as water swellable binder polyvinyl alcohol, cellulose ether or alginate
Inventor: DUDZIK JOACHIM
IPC: A61K9/70
Filed: 1980-11-14
Abstract: The parent patent describes a tablet consisting of a carrier, contg. at least one active ingredient (A), which is an absorbent fibre fleece and includes a water-swellable binder. It automatically decomposes into a fibre slurry when the binder swells. (A) is either metered onto the surface of the carrier, or injected into it. Improvement is that the binder is polyvinyl alcohol (PVA); a water-soluble cellulose ether or a water-soluble alginate. (I) is esp. a nutrient; pharmaceutical or chemical compsn.; a plant seed or animal semen, and the fibre fleece is pref. of cellulose, esp. paper or textile. The parent patent suggests gelatin and bone glue as binders, but these do not have consistent swellability or water-solubility properties, esp. in cold water. The properties of the new binders are more reproducible and controllable.

Title: Process for the preheating of viscous fuel
Inventor: PANICK KARL
IPC: F23D11/44
Filed: 1981-03-18
Abstract: In order, in a heating appliance in which viscous fuel is burnt, to avoid the need for the preheating, necessary at very low initial temperatures, of the fuel quantity to be sprayed out first or of the nozzle or nozzle bank normally taking effect shortly before the heating appliance is switched on, a long-time heating or continuous heating of the nozzle is to take place, and this, with a low heating capacity, keeps the nozzle and the fuel quantity already located in it at a temperature increased in relation to the low ambient temperature.

Title: Device for determining the material separation parameters of rotating tools
Inventor: HUEBSCHER HANS-JOACHIM DIPL PH
IPC: G01N3/58
Filed: 1981-04-10
Abstract: The device serves for investigating the material separation properties of rotating tools by means of which organic and/or inorganic material is machined. In particular, the separation parameters of a motor trephine used in ophthalmic surgery can be determined under the most varied conditions. This is achieved by mounting the material specimen rotatably below the rotating tool, and arranging the cutting tool or the material specimen on one side of a double-sided lever or hollow-plunger system which acts as a force-transmitting system, while a receptacle for weights for the pressure force is located on the other side. Furthermore, an adjustable stroke limiter is arranged on the holder which supports the tool, and is connected to a timer via electric leads, or a displacement sensor which makes it possible to record the temporal change in position between the tool and material specimen is attached. A thread whose ends act on both sides on a force measuring device is wound on a cylindrical rotating element of the holder for the material specimen in order to measure the torque transmitted to the material.

Title: Device for inserting sleeve core (M-core) laminates into a coil former
Inventor: WAASNER BRUNO
IPC: H01F41/02
Filed: 1981-09-16
Abstract: A device exists for the reciprocal insertion of sleeve core laminates having an open yoke into a coil former, in the case of which device a holding appliance (17) for the coil former is arranged between two magazines (1) for the laminates, and two slides (3) which can be displaced in a reciprocating manner horizontally and are coupled to one another in each case alternately remove a laminate downwards from the associated magazine and move it into the region of the holding appliance for the coil former. In this case it is desirable for sleeve core laminates having an open yoke to be interleaved with disturbances (defects) being avoided, in that the two outer limbs on the one hand and the centre limb on the other hand are pressed apart from one another before insertion or for insertion. This is achieved in that the holding appliance (17) holds the lower region of the coil former window at the level of the slides (3), and guiding devices (15, 16, 26, 27, 31, 38) which press the two outer limbs of the core laminate downwards and a guiding device (18) which presses the centre limb of the core laminate upwards are provided in each case between the holding appliance and the magazine (1), in that two inclined tabs (31), which are allocated to the outer limbs, project deeper downwards from above than an inclined ramp (18), which is allocated to the centre limb, projects upwards from below. This device operates without disturbance and carries out the interleaving operation until the window is full. <IMAGE>

Title: Fuel-heated heat source
Inventor: VAILLANT KARL-ERNST DIPL ING
IPC: F24H9/20
Filed: 1982-02-10
Abstract: The present invention relates to a fuel-heated heat source with main burner and pilot burner and a blower lying along an air supply or air removal pipe for forced aeration of the firing chamber of the heat source. If, in such a heat source, no heat is required, the blower stops while the ignition gas burner continues to burn. Under unfavourable operating conditions, it can in this case lead to overheating of the firing chamber and of the heat exchanger which extends through the firing chamber. To avoid this overheating, a temperature sensor is provided in the firing chamber, which sensor causes the blower motor to run for a short time in the event of a set limit temperature being exceeded.

Title: Sorting device for a copier
Inventor: HARAMAKI TOSHIO
IPC: B65H39/11
Filed: 1982-03-10
Abstract: A sorting device for a copier, wherein the sorting device is pivotably attached to the copier and thus allows easy access to the paper transport path in order, for example, to eliminate blockages of paper. The sorting device has a transport system and a sorting mechanism, the transport system being mounted fixedly at the output of the copier and being fitted with transport rollers which transport the paper to the sorting mechanism. The sorting mechanism has an input opening and a plurality of chambers which serve for receiving the copies. The sorting mechanism is pivotably attached to the transport system and can be pivoted from a closed position to an opened position in order to allow access to the paper transport path of the sorting device. In the case of a blockage of paper, the operating personnel can open the sorting mechanism with a horizontal pivoting movement and thus easily reach the jammed paper. Furthermore, the jammed paper can be removed easily and quickly in the direction of the paper transport path without fear of the paper tearing.
