Abstract: An infrared intrusion detector having a predetermined number of rows of radiation reception zones comprises a primary reflector and a secondary reflector for each row of radiation reception zones. The primary reflectors and their associated secondary reflectors form a folded radiation path. The folded radiation path allows for compact construction and simple manufacturing of the infrared intrusion detector. One reflector of each radiation reception zone forms together with the infrared sensor a compact structural unit. The other reflectors of each radiation reception zone are combined to form a further structural unit which is arranged in a predetermined spaced relationship to the first compact structural unit. In order to achieve uniform detection sensitivity in radiation reception zones having different angles of inclination to the horizontal plane, a larger focal length is chosen for radiation reception zones with smaller angles of inclination and longer range. Likewise, to achieve uniform detection sensitivity even with oblique infrared radiation impingement, the surface area of the primary reflectors increases within each horizontal row from the middle to the sides.

Title: Manipulator gear head
Inventor: ZIMMER ERNST
IPC: B25J17/02
Filed: 1986-07-15
Granted: 1989-06-22
Abstract: The invention is a further development of the gear-head unit for a manipulator described in German Open Patent Application No. 34 28 748. In order to increase the radius of action and range of applicability of the gear-head unit a structural arrangement with three concentric drive axes and four allowed rotational motions of front, intermediate and rear segments of the manipulator is set forth. These front, intermediate and rear segments are pivotally mounted together about first and second inclined pivot axes which are inclined to each other and to the main drive shaft axis. Along these inclined pivot axes two hollow drive shafts connected with each other extend which are supported by reduction gears in the front and/or intermediate segments. Because of that simultaneous opposing rotational motions of the intermediate and rear segments can be obtained from a single drive motor. In the rear segment an output drive shaft attached to a front plate for a tool holder is rotatably mounted which is driven by coupled intermediate drive shafts guided through the hollow drive shafts.

Abstract: The main body of the punch, namely base portion (20) and support portion (19), is formed as an extruded profile, e.g of aluminium. Respective end plates (11, 12), e.g. of moulded plastics, are preferably fitted thereto to maintain overall strength and rigidity so that the thickness of the extruded material can be reduced. The length of the extruded profile and the positioning of openings (42, 43) for cutting tools (15) can be varied without the need for new production moulds, thereby simplifying and reducing the cost of production of a range of different sizes of punch. 
<??>The main body of the punch may alternatively be formed of two or more extruded profiles. 
<??>Press bar (14) may also be formed as an extruded profile.

Abstract: A bidirectional heat transfer system including a reversing valve and a compressor has a compressor control which is subject to a welded contact failure. The system is monitored to determine when the control system has signaled for the compressor operation to stop but the compressor has, in fact, continued to operate. Under these circumstances, a safety mode of operation is commenced to keep a load on the compressor to thereby save the compressor from self-destruction. Preferably, this is done by repetitively reversing the state of the reversing valve.

Abstract: An optical arrangement of the Michelson interferometer type having a measuring arm for measuring optical properties of at least two mutually spaced regions in an optically transparent and/or diffusive object. A reference arm has a path length variation unit which generates a periodic change in path length for the radiation in the reference arm. Arranged in the measuring arm upstream of the object is a detour unit. The detour unit imparts a detour which is larger than at least one second measuring beam into at least one measuring beam. The detour unit selects a detour to be equal to a distance between regions to be measured in the object. Using the optical arrangement the object is irradiated with the aid of a number of measuring beams corresponding to the number of regions. In each case two measuring beams have an optical path difference which corresponds to a geometrical distance between two regions. Each reflection beam of the measuring beams which is reflected by one of the regions is superimposed in an interfering fashion with a third beam having a temporal variation in path length, and is detected. This arrangement can carry out "in-vivo" measurements of distances, thicknesses, at and/or in the human eye with the minimization of measuring errors within a sub-second time. The object does not have to be fixed during the measurement.
