Abstract: Improved catoptric reduction imaging systems of a quassi-Cassegrainian type are presented wherein light from an object enters an imaging system through an aperture in one mirror of an imaging system and leaves the imaging system through an aperture in another mirror of the imaging system to form an image. In each imaging system, the sums of the inverses of the radii of the mirrors effecting each reflection are constrained to be substantially zero. 
     In a first improved catoptric reduction imaging system, two mirrors (12, 14), one convex and one concave of equal base radii, are disposed axially, light from the object (16) enters the imaging system through an aperture in the concave mirror (14), reflects from the convex mirror (12) to the concave mirror and reflects from the concave mirror to form the image (20) positioned beyond the convex mirror through an aperture (22) in the convex mirror. 
     Three alternative arrangements are disclosed.

Abstract: The descaler is designed as an angled piece (1) with a grip housing (2) and a tool housing (3) arranged at an angle thereto. A scraping device (27) can be inserted in the tool housing (3) in a bearing sleeve (24) mounted at its ends in bearings (28, 29), at different angular positions relative to the periphery of the bearing sleeve (24), can be displaced, and can be fixed by turning a clutch ring (42) by means of clutch members (46). Mounted in the grip housing (2) is a drive shaft (55) at whose end face (56) an eccentrically arranged carrier pin (57) and a coaxial bearing pin (58) are secured. On the bearing pin (58), an eccentric member (59) is pivotable about an angular range, which is defined by the size of a recess (61) arranged in the eccentric member (59). A spring-loaded rocker (63) co-operates with the eccentric member (59). The rocker (63) effects the jerky movement of the scraping device (27) relative to the tool housing (3) when the eccentric surface (67) recessed on the eccentric member (59) is directed towards the rocker (63). The descaler is of a simpler and more manageable construction than known descalers. …<IMAGE>…

Abstract: Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes a pair of probes (54) mounted on each ski that protrude below the running surface (14) of the ski and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts his run, or during his descent. Having deployed the probes, added maneuverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow.

Abstract: An interference detecting circuit is used in a cellular radiotelephone communication system which employs angular modulated frequencies in order to determine when to change the communication process so as to maintain the integrity of the communication path. For example, when the circuit detects an excessive amount of multipath or co-channel interference on a channel serving an active call, the system attempts to handoff the call to another channel. Also, when the circuit detects an excessive amount of multipath or co-channel interference on a channel serving an active call, the system may decrease the effective data bit rate. The circuit includes a logarithmic envelope detector 150 for receiving a channel's angular modulated signal and for providing a log envelope output signal, a high pass filter 152 for removing a particular range of undesired frequencies from the log envelope output signal, and a level detector 154 for indicating the level of filtered output signal. The output of the level detector represents the amount of interference on the angular modulated frequency signal. A microcomputer analyzes the amount of interference to determine when such communication process changes are desired or to determine if a handoff is required.
