Title: Method and device for the axial adjustment of a sleeve mounted loosely on a roll, in a roll stand
Inventor: OGAWA SHIGERU
IPC: B21B37/40
Filed: 1981-01-27
Abstract: A roll stand having at least one roll which loosely carries a sleeve, where the sleeve is tilted slightly by the application of radially inward-directed forces at two spaced locations on the outer circumferential surface of the sleeve in order to displace the sleeve or limit the displacement of the sleeve in the axial direction, the locations at which forces are introduced being independent of the direction of rotation of the sleeve, with the result that only one device for introducing forces is necessary, even when the direction of rolling is reversed. By controlling the relative value or difference between the two forces, camber control can be achieved in the case of rolling stock of varying width. The guide means for the sleeve have an increased service life even at high rolling speeds for mass production.
Patent DE-3106333-A1 (DE)
Title: An apparatus for lifting and tilting containers
IPC: B65F3/04
Filed: 1981-02-20
Abstract: An apparatus for lifting and tilting containers, especially for emptying refuse vessels in refuse collection vehicles, consists of a lifting and tilting frame which receives the container, a pivot arm which supports the lifting and tilting frame via a four-bar linkage, and an actuating device for raising or lowering the lifting and tilting frame relative to the pivot arm in order to raise and lower a received container and pivot the pivot arm in order to tilt the container. Such a lifting and tilting device is to be significantly improved, to the effect that excess stresses and tensions occurring at the wall of the container which is to be emptied within the lifting and tilting frame are restricted to an acceptable extent, and elements sliding over the container wall with friction are to be avoided. It is therefore proposed that a separate container bearing piece (10), movably affixed in the lower part of the four-bar guide, and devices (12) for deriving the movement of the container bearing piece out of the position of rest into the operating position, and vice versa, from the lifting and lowering movements of the four-bar guide (15) relative to the pivot arm (23) are provided. It is also proposed that the container bearing piece (10) has devices (11) for support in the operating position relative to the pivot arm (23). The most varied embodiments are possible. For example, direct pivotable attachment of the container bearing piece (10) by means of a supporting lever (11) on the pivot arm, using a flexible or articulated tension member in order to bring the container bearing piece into its operating position when the lifting and tilting frame (20) is raised. Another possible embodiment comprises fixedly attaching an additional pivot lever on the container support piece above the support lever, by means of which additional pivot lever the container bearing piece can be suspended freely on a connecting rod of the four-bar guide. Finally, the container bearing piece with its support lever can also be fixedly attached to a lower connecting rod.   <IMAGE>

Title: Air inlet ducts on heating appliances and systems
Inventor: AUGUSTIN FRITZ
IPC: F02C3/00
Filed: 1981-07-10
Abstract: The invention belongs in the sphere of heating technology. It is intended for saving energy. By utilising the movement of the combustion air of heating appliances, air inlet ducts are according to the invention assigned to the heating air flow. Due to the chimney effect of the air inlet ducts the heating air flow is increased. Due to the funnel-shaped enlargement of the air outlet shaft a larger cross section of the heating air outlet is achieved. This enlargement produces the optimum functioning of the air inlet ducts. The secondary air obtained from the air inlet ducts due to the ascending current of heating air does not produce any acceleration of the heating air but, due to the enlargement of the air outlet shaft, an increase of the air outlet flow. The drive force from the heating air and the secondary air generates current by way of a large-bladed generator, the ratio of heating air movement and secondary air flow being the determining factor. One possible application would be the self propelling heating fan as shown in the attached drawing, Fig. 1.   <IMAGE>
