Title: Metering and distributing device for granular bulk materials
Inventor: HEGE HANS-ULRICH
IPC: B65G65/48
Filed: 1982-11-27
Abstract: A metering and distributing device for granular bulk materials, in particular seeds, fertilizer or the like, is proposed which ensures precise and complete metering and distribution of the bulk material (51) to a plurality of discharge pipes (37) of a rotary distributor (33-36), and thus also avoids the mixing of residual amounts of one bulk material with another bulk material previously introduced. This is achieved by 1. an externally mounted cylinder (49) which forms an accumulating space without internal support struts and can, in addition, be exchanged for the purpose of working with different capacities, for upper cylinders having the same outside diameter, which is matched to the mount (38), but having a different hollow space; 2. a cover element (19) which covers the discharge aperture (16, 20) from the metering space (11), formed by a cone (6) and a strip (9), against bulk material (51) arriving from the accumulating space in the direction of fall; 3. a rotating collecting funnel (22, 23) of a rotary distributor (33-36). It is advantageous to introduce into the collecting funnel (22) a swirling device (26) which can consist of at least one bar (26) protruding radially into the interior of the collecting funnel (22).

Patent DE-3302461-A1 (DE)
Title: Method and arrangement for realising acoustic impedances
Inventor: SCHROETER JUERGEN DIPL ING
IPC: G10K11/02
Filed: 1983-01-26
Abstract: The invention relates to a method and arrangement for simulating acoustic impedances, for example that of the ear in the form of an ear simulator. Instead of the previously customary Helmholtz resonators, use is made here of acoustically active spur lines which are coupled to a main line. The input impedance of a spur line can be set in wide limits by selecting the respective inside diameter, the respective length and, as the case may be, the acoustic impedance of the termination used. Spur lines can be produced in a simple way for high resonance frequencies, as well, and this is more difficult for Helmholtz resonators. An exemplary embodiment having a total of eight spur lines arranged in parallel is shown in Figure 1. <IMAGE>

Title: Front end dog
Inventor: BELTHLE HEINZ ING GRAD
IPC: B23B33/00
Filed: 1983-10-24
Abstract: In the case of a front end dog, so that workpieces held between two lathe centres and having different diameters in each case can be held in place at the ends in such a way as to be rotable in their axis and can be rotated for machining by cutting machine tools without having to take manual measures to set the dog to a given workpiece diameter in each case, dog blades 5 and 6 running radially one behind the other are fastened on circular paths 10 and 11 which are at a distance from one another and are arranged concentrically to the centre point of the dog plate. Here, each circular path defines a different workpiece diameter relative to the other circular path. The dog blades running radially on the dog plate are alternately staggered 25 and 26 relative to one another from row to row, the individual blades 5, 6 in each case rising uniformly in their height from the centre up to the periphery of the dog plate 2. This design of the dog enables workpieces 20 held between two centres and having a minimum diameter D1 up to a maximum diameter which can still be covered by the peripheral blades to be acted upon at the ends in a rotatable manner and set in rotation without it being necessary to always manually set the dog blades arranged in a circle to a corresponding workpiece diameter. <IMAGE>

Title: Flush-mounted installation apparatus
Inventor: MUHL HORST-DIETER
IPC: H02G3/18
Filed: 1983-12-23
Abstract: A flush-mounted installation apparatus is provided with expanding claws which can be spread apart after installation. Before and during installation, the expanding claws are held in contact with elastic latching hooks which are arranged in a base, by means of said latching hooks. If the base consists of plastic, the latching hooks are preferably injection-moulded thereon. When the expanding claws are spread apart - for example by screwing a screw into the base, in which case a bent part of the expanding claws is pivoted downwards, and hence the expanding fingers of the expanding claws are pivoted outwards - the expanding fingers of the expanding claws are forced to move out of the latching hooks and lie on the inside of a recess in a flush-mounted empty socket or the like, so that the flush-mounted installation apparatus is held in its installation opening.

Title: Centre clamping blocks for clamping workpieces on machine tools
Inventor: SALZER KURT
IPC: B23Q3/10
Filed: 1984-01-11
Abstract: The invention forms a complete set of accessories for machine tools. System clamping means, for example in the form of standard units, are expanded by integrating centre clamping blocks in their field of use.   In the production of accurate rotation parts these are generally provided with centring bores according to DIN 332 and are turned or ground between centres. An essential feature of the invention is to be able to utilise the known advantages of this clamping method for multilateral surface machining. In particular, the problem of clamping a large number of workpieces to be milled is solved. Workpieces whose principle machining operations lie in several circumferential planes are ideally suited for machining between the centre clamping blocks. Workpieces with predetermined shape and positional tolerances according to DIN 7184 should be emphasised in particular. A particular advantage arises in the use of the invention on NC- and CNC-machines. Extensive machining operations can be performed in a program sequence when the workpiece is clamped just once.
