Title: Apparatus for mixing and homogenising preferably paste-like mixes
Inventor: BERENTS ALWIN
IPC: B01F7/02
Filed: 1983-11-18
Abstract: Apparatuses for mixing, in particular, paste-like mixes, for example creams, ointments and the like, must achieve complete blending of the whole mix, even if the batch is small. In addition, it should be possible to empty them completely and to clean them easily. Known apparatuses of this type meet these requirements only in part. The invention therefore proposes an apparatus in which the mixing vessel (10) is arranged at an angle in a frame (14), with a central drive (18) of the agitator (anchor agitator 15) from the bottom of the mixing vessel (10). As a result of the inclined position of the mixing vessel (10) complete blending of the mix is possible, including blending in the vertical direction. In addition, the inclined mixing vessel (10), as a consequence of the centred drive, has an eccentrically positioned outlet port (19) which - as a result of the inclined position of the mixing vessel (10) - nevertheless is located at the lowest point thereof. Complete emptying, and the mixing of small batches, are likewise ensured by this arrangement. The cover (13) of such a mixing apparatus can easily be swung open by means of a hinge (33), for easy cleaning of the apparatus. <IMAGE>

Patent DE-3437960-A1 (DE)
Title: Lathe
Inventor: LAUTENBACH FRIEDRICH
IPC: B23Q3/16
Filed: 1984-10-17
Abstract: Lathes contain a holding device which can be set in rotation by a drive and which is intended for the workpiece to be machined, the holding device containing radially displaceable clamping elements. The larger the workpiece and the further the clamping elements are therefore displaced outwards, the greater the risk that the clamping forces will be cancelled by the centrifugal force and the clamped workpiece will be capable of coming loose from its mounting. To prevent this, there is arranged along the displacement path of at least one of the clamping elements a control device which limits the rotational speed of the holding device as a function of the radial position of the clamping elements, thereby automatically preventing the possibility that inadmissable circumferential speeds will occur when the clamping jaws are extended too far.

Filed: 1984-11-09
Abstract: A novel comb attachment for use with a hair clipper is disclosed herein. The comb attachment is adapted to fit over the front portion of the hair clipper including a cutter assembly having an elongated cutting edge. The cutter assembly comprises a movable cutter reciprocating with respect to a stationary cutter, these cutters defining therebetween a cutting plane. Formed in the front end of the attachment is a series of spaced comb teeth the row of which is in close and parallel relationship with the cutting edge of the cutter assembly for guiding hairs into the cutting edge. Each of the comb teeth is formed at the location above the cutting plane with at least one barb projecting on its side and upper faces to define therebehind a rearwardly oriented shoulder. These shoulders act as stoppers for the clipped hair strands which have been sheared and fed rearwardly of the cutting edge when advancing the hair clipper through a user's hair for a continuous hair cut. Accordingly, the clipped hair strands can be well prevented from gliding back to the tips of the comb teeth and into the cutting edge during the advancing movement of the hair clipper, whereby assuring a smooth cutting action which is free from the reentry of the clipped hair strands in the cutting edge, while retaining a smooth combing action by the comb teeth.
