Granted: 1991-07-23
Abstract: ABSTRACT      Fastener installation apparatus for operating cyclically so as to instal successively a plurality of fasteners of the type in which a portion is broken off at installation (e.g. breakstem blind rivets) comprises a fastener installation head (11) and a pipe (31) for conveying the broken-off portions away from the head to a receptacle (15).  Detection means (48) is mounted adjacent the pipe (31) to detect the presence of a broken-off fastener portion at a pre-determined position (58) there along near the receptacle (15).  When a portion is thus sensed, an electrical signal is sent by the detection means (48), via a relay (51), to the installation control system (14a, 14b), so as to allow cyclical operation of the system to continue.

Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE          A novel method for manufacturing cement utilizing crushed refuse.  The method comprises a first step of preparing a homogeneous powder mixture from a majority of crushed refuse substantially free of metal constituents and a minority of at least one first mineral material containing calcium oxide in the free or combined state.  In a second step, the powder mixture is granulated under pressure.  A third step comprises heat treating the granules at a temperature between 130°C and 230°C for a length of time sufficient to bring the water content of the granules to between about 0.1 and 1.0% by weight. The third step produces a refuse product.  A fourth step comprises mixing the refuse product with a first starting mixture and firing the resulting clinker mixture in a kiln, producing a clinker.  In the last step, gypsum is added to the clinker and the resulting cement mixture is crushed.

Abstract: ABSTRACT      Drive unit for a vertical blind or the like, where the slats of the vertical blinds can be moved by an endless pull element, such as a pull chain.  The drive unit has a housing (5) formed, for example, of plastic, an electric drive motor (6) placed in the housing (5), and a drive pinion or the like coupled to the drive motor, optionally by an inserted reduction gear.   By enclosing of the drive components within the housing, a safe and unobtrusive drive unit is created.  Preferred embodiments of the unit are constructed to enable the pull element  to enter  the  housing through  openings therein and be hung on the drive pinion.   By this construction and the provision of control switches on the housing for operation of the electric drive motor, the  drive  unit  is  inexpensive  and  able  to  be retrofitted simply and versatily.  Additionally, in an emergency, easy hand operation of the vertical blinds is still possible.   Still further, the drive unit is designed to enable mounting of it in each of two positions  that are displaced  180°  relative  to  each other by the provision of openings for the pull element at each of opposite sides  of  the housing and by enabling the mounting position of the switch controls to be  inverted relative  to the  remainder  of  the housing.
