Patent DE-3305446-A1 (DE)
Title: Coal bunker comprising self-supporting flanged plates
Inventor: LAMPFERHOFF JUN ALOYS
IPC: B65D88/26
Filed: 1983-02-17
Abstract: Fully automatic, dust-free coal heating-boiler installations are equipped with a coal bunker which is adapted in its shape and capacity without great expenditure to the respective conditions, in particular to basement areas. The coal bunker comprises individual constructional elements or plates which are preshaped in a modular fashion and are of a flanged design at the sides. These flanges have punched slots, so that such coal bunkers can be assembled without any welding work even in the most difficult positions in a simple way and without great expenditure. The flanges serve as reinforcing ribs and also make it possible to attach continuous flat bars to reinforce large coal bunkers. <IMAGE>
Patent DE-3306621-A1 (DE)
Inventor: KORNRUMPF WOLFGANG DIPL CHEM D
IPC: C08B11/00
Filed: 1983-02-25
Abstract: In modern processes for the preparation of cellulose ethers containing one or more types of substituents (such as MC, CMC, HEC, HPC, MHEC or EHEC), cellulose is reacted with etherifying agents in the presence of water, base and a mixture of preferably inert organic solvents (as a dispersing auxiliary). Dimethoxyethane (ethylene glycol dimethyl ether) and at least one organic solvent selected from the group including alkanols, alkane diols and alkoxy alkanols (for example, methanol and/or isopropanol) are employed in the mixture of organic solvents used for these syntheses, particularly in quantities of 1 to 30 parts by weight per 1 part by weight of cellulose.

Title: Form-truing attachment for double-tapered grinding bodies of tooth-flank grinding machines
Inventor: SOBCZYK REINHARD DIPL ING
IPC: B24B53/08
Filed: 1983-07-09
Abstract: Form-truing attachment for truing any circular arcs, tangent to the profile, for double-tapered grinding bodies of tooth-flank grinding machines, with a truing tool arranged on a driven pivoted lever. The aim of the invention is to achieve short machining times by means of the greatest possible stiffness of the tool. This is achieved by the bearing element of the pivoted lever having a surmountable resistance hindering the displacement of the pivoted lever and by being arranged in such a way that it can itself be displaced between two end points against a smaller resistance. It is of advantage if the end points can be set by means of stops. Furthermore, it is advantageous if the resistances are independent of the drive direction of the pivoted lever. <IMAGE>

IPC: B60N2/48
Filed: 1983-09-05
Abstract: The housing 12 is provided with a bore 20 and an opening 22 which extends in the transverse direction relative to the bore 20 and intersects the latter. The actuating device 16 is in snap-on engagement with the housing 12 in order to hold the spring 14 in the opening 22. At least one part of the actuating device 16, for example the arm 30, is movable in the inward or outward direction of the opening 22 in order to vary the extent to which the spring 14 impedes the bore 20. The spring fastener 10 is used in particular in the removal or adjustment of headrests on the backrests of vehicle seats. Even if it is concealed by the upholstery on the backrest of the vehicle seat, the arm 30 can easily be squeezed in order to release the spring 14 from the lug ring extending downwards from the headrest. <IMAGE>

Title: Table for a child's car seat
Inventor: HEIDER HANS
IPC: B60N2/28
Filed: 1984-04-05
Abstract: By means of the invention, an attachment for the table of a child's car seat is provided which comprises a plate made of flexible material which fits the dimensions of the table and in which the axle of a steering wheel which can be rotated by the child is mounted. The upper side of this plate is provided with the controls of a car dashboard so that the child has the impression of sitting himself at the steering wheel of a car. In the plate there are also displays, for example in the form of a picture disc connected to the steering wheel axle, which disc bears images on its upper side and, when the steering wheel is turned, runs past below an opening in the plate above the disc so that the child can view moving images through a window in the plate. The plate and steering wheel and axle consist of material which is sufficiently soft to exclude any risk of injury to the child in the case of an accident and, moreover, provides a softer surface for the child to strike against than the table of the child's car seat. <IMAGE>
Patent DE-3422297-A1 (DE)
Title: Picture stage for a photographic enlarger
IPC: G03B27/62
Filed: 1984-06-15
Abstract: Picture stage (6) for a photographic enlarger, which has an automatic transport drive (1) for films (27) and automatically proceeding acquisition of measured values and simplifies working with enlargers. For the purpose of optimum matching to the film material to be processed, the picture stage (6) and the transport drive (1) can be exchanged via guide bolts (5) and guide bushes (54). A light-measuring device (37) having light sensors (38) and light-conducting rods (39) scans the film (27) by the rotary movement of a spindle (36). A picture is projected on a pivotable diaphragm (29) via a positive lens (32). A measuring cell (33) detects the reflected light and converts the integrally measured light intensity into an electrical pulse. The movable carrier plate (31) serves as a receptacle for the positive lens (32) and for the measuring cell (33). The film-supporting window (13) can be lowered by means of displaceable wedges. An expanded design of the picture stage consists, in addition, of a supply magazine and collecting magazine. A guide groove connects the two magazines. A driver pin, driven by a spindle, conveys a framed slide in the guide groove up to the picture gate. After exposure has been performed, the slide drops into the collecting magazine via a slope. <IMAGE>
Patent DE-3424421-A1 (DE)
Title: Gearing with mechanical power transmission for the infinitely variable adjustment of torque, speed and direction of rotation
Inventor: RUDOLF WALTER
IPC: F16H37/10
Filed: 1984-07-03
Abstract: The gearing is characterised by the differential load distribution of the input torque by the differential gear mechanism 1 between the two transmission stages 8 and 9, of different dimensions, which represent the smallest and the largest transmission ratios. The torque is allocated to the two transmission stages as a function of loading and the desired speed by control by way of alternate actuation of the hydraulic brakes 5 and 6 or of both brakes simultaneously. In the differential gear mechanism 2, the torque from the two transmission stages is recombined and passed to the output 4. By appropriate control of the hydraulic brakes 5 and 6, the gearing can be used without special arrangements as a retarder (wear-free brake). With the exception of a change in the direction of rotation, all the gearwheels are permanently in engagement. Power is transmitted in a purely mechanical manner, the hydraulic brakes merely providing the "counterweight" for the allocation of the torque to the two transmission stages. If the hydraulic brakes 5 and 6 are equipped with lock-up clutches, a return flow of power and braking at a standstill are possible. <IMAGE>

Title: Wind vane arrangement on aircraft wheels
Inventor: FRIES HERBERT
IPC: B64C25/40
Filed: 1985-01-22
Abstract: Wind vane arrangement on aircraft wheels. The wind vanes prevent the excessive wear of the tyre rubber when the aircraft is landing. The wind vanes are arranged inside the rim and project somewhat laterally on the rim. The vanes extend from the wheel hub to the edge of the rim. They are bent in the direction of the wind's motion. As soon as the undercarriage is lowered, the vanes give the wheel a relatively high speed of rotation and thus result in less wear of the tyre rubber, and less noise.
