Abstract: PHN.9763                                        20.1.81 ABSTRACT "Dry-shaving apparatus with hair-trimming means"     A dry-shaving apparatus is provided with hair-trimming means comprising two pairs of cooperating toothed cutters, each pair consisting of a reciprocating cutter and a stationary cutter. One pair of cutters (6 or 7) is adjustable between different positions and forms a first hair trimmer of relatively short length for trimming hairs which are not easy to get at with a full-length trimmer, for example, hairs in the ears. The other pair of cutters (5 or 9) is either arranged for operation in line and in juxaposition with the first pair in one of the positions thereof so as to form with the first pair of cutters a second trimmer of greater length than the first trimmer, or has a greater length than the first pair of cutters and forms a full-length second hair trimmer independently of the first trimmer. (Figures 1, 2 and 3).

Abstract: TIME DIVISION SWITCHING MATRIX ABSTRACT OF THE DISCLOSURE           A time division switching matrix which receives time division multiplexed signals on a plurality of input lines according to a first sequence and switches them to a plurality of output lines according to a second sequence, after storage in a data memory.  A controller can read any of the signals stored in the data memory and can also substitute data signals on the output lines in place of the signals stored in the data memory. Accordingly the switching matrix controller can receive data signals destined for it on the same PCM lines which normally carry PCM input voice signals, and can transmit data or control signals on the same output PCM lines as would normally carry PCM output voice signals.  Controller to controller communication on the PCM lines can thus be obtained throughout an extended network, without providing separate controller communication lines.

Abstract: ABSTRACT OF THE DISCLOSURE A method for thermally treating pulverulent material, i.e., keeping the material at a certain temperature, the treating temperature, in a desired period of time, in particular sintering, pulverulent material in a rotary kiln slightly inclined to the horizontal. The method is especially applicable for thermally treating materials which tend to become sticky at the treating temperature, in particular for sintering pulverulent materials, i.e., agglomerating these by heating without complete melting. However, the method is also useful for general thermal treatment where sintering is not intended, e.g., for burning Bauxite, Mesa and phosphate bearing ores. An example of a sintering process to which the invention is particularly applicable is the manufacture of cement clinker where the pulverulent material to be sintered is hot calcined cement raw meal. An apparatus for practicing the method of the present invention is also disclosed.

Abstract: Apparatus for Projecting a Series of Images Onto Dies of a Semiconductor Wafer Abstract An apparatus for forming on a semiconductor wafer unit magnification  images  of  a  reticle  pattern.   A  reticle (20-30)  containing an image pattern corresponding to  the size of the desired wafer pattern is substantially uniformly illuminated (34-47) to produce an image which passes through a one-to-one stationary projection optical system (50-59) to form an image of the reticle pattern at a predetermined focal  plane.   A  selectively  positionable  vacuum  chuck (79-83, 201, 202, 302, 303) holds the wafer.  An alignment system  (60-78)  steps  and  orients  the  chuck  to  register markings on the  individual  sides  of the wafer with the projected image of corresponding markings on the reticle.  A fluid servo system (100-139) acts on the chuck to hold at least a portion of the wafer in the predetermined focal plane of the projection optical system.

Abstract: MICROBENDING OF OPTICAL FIBERS FOR REMOTE FORCE MEASUREMENT              ABSTRACT OF THE DISCLOSURE           A system for remote measurement of structural forces includes  a plurality of microbend  transduc-ers mounted along the length of the structure for micro-bending  an optical  fiber  in response to structural forces, such as stress acting upon an oil or gas pipeline or  the like.   An optical time domain reflectometer (OTDR) has a light source for launching a pulsed optical signal for passage through the fiber and a photodetector for sensing  as a function of time the intensity of backscattered  light  reflected  back  through  the  fiber, wherein this sensed time function is correlated directly with discrete longitudinal positions along the length of the fiber and the structure.  When one or more of the microbend transducers is activated to induce a microbend in the fiber in response to localized forces acting upon the structure, a portion of the backscattered light is lost at the microbend.  This attenuation in backscattered light intensity is sensed quantitatively and positionally identified by the photodetector. Specific preferred constructions  for  microbend  transducers  and  system arrangements particularly adapted for detecting structur-al strain in an oil or gas pipeline are disclosed.
