Abstract: An automatic lead sensing and fine-forming system is disclosed for preparing the leads of electronic components so that they are ready to be inserted by robots into holes on printed circuit boards. The positions of the lead tips and the positions of the holes are sensed and compared to determine if any leads need to be bent. These leads are then bent and the force on the leads and their displacement are sensed and recorded during the process. The data recorded is then used for subsequent bendings, where necessary, for bending the leads to the target locations so that all the leads fit simultaneously into the holes. To simplify image processing, the lead tips are illuminated by light originating from substantially isotropic directions from locations substantially coplanar with the region of the lead tips. A telecentric lens system is used in the optical sensing of the position of the lead tips so that measurement of the distances between leads is unaffected by variations in the separation between the lead tips and the sensing device.

Abstract: An opto-electronic switch which shows a good signal rejection ratio between modes is also of particularly small dimensions. 
     The switch comprises a semiconductor laser 1 having four contacts 12, 12ʹ, 13, 13ʹ which provide gain guiding under two stripe windows 18, 19. By varying the bias currents supplied to the individual contacts 12, 12ʹ, 13, 13ʹ, or by inputting optical control signals to the waveguiding channels under the stripe windows 18, 19, different configurations of optical output from the laser 1 can be achieved. The two contacts, 12, 12ʹ and 13, 13ʹ, associated with each stripe window 18, 19 are effectively a single stripe contact with a discontinuity. It is thought that diffractive transverse coupling at the discontinuity allows the use of a shorter device than in known directional switches. With feedback, the switch operates as a memory device. 
     The switch finds particular application in optical communications, for instance in signal routing.

Abstract: A self-compensating seal (10) has a substantially toroidally shaped seal body (12) and a plurality of axially separated annular wipers (14,16, 18) extending radially inwardly from the inner rim of the seal body in parallel arrangement. When a shaft or rod (36) (see Fig. 5) having a diameter greater than the inside diameter of the seal opening is inserted through the central seal opening, the wipers (14,16, 18) are bent or collapsed so as to extend in an axial direction. Each of the wipers (14, 16, 18) is radially inwardly biased by an O-ring (32, 34) so that wear at the sealing surfaces of the wipers caused by shaft movement is compensated for.

Abstract: It has been found that in roll-bending machines with long rolls, inaccuracies in the bent product occur even if the synchronising control of the side rolls (3) works faultlessly. It has now been found that this is a consequence of the unsymmetrical deflection of the top roll (1) and that this fault can be rectified by a correction member (30) in the synchronising control, this correction member being intended to set the side roll (3) in an appropriate oblique position. This correction element can be an element (30) which is inserted between the synchronising valve (31) and the bearing (20) of the synchronising shaft (9) and whose effective length is changed in proportion to the pressure p acting on the bottom roll. <IMAGE>

Abstract: Methods and apparatus for use in quantifying components in a liquid sample, for example, white blood cells in blood. The invention provides a microscope slide for such use having at least one adhesive matrix, which is soluble in the liquid sample having components to be quantified, affixed to the operative face of the slide, and a plurality of substantially spherical beads of uniform diameter made of a substantially non-compressible material located within the adhesive matrix. A counting chamber is provided when a cover slip is provided with the slide. The invention further provides a stirring rod for use in quantifying components in a liquid sample having an adhesive matrix over one end portion, the adhesive matrix being analogous to the adhesive matrix on the microscope slide described above. The adhesive matrix or matrix can consist of a solid residue of dried liquid, and the liquid can be a hemolysing solution if the equipment is to be used for counting white blood cells. A standard microscope slide is provided by the invention when the adhesive matrix made of a solid residue of dried hemolysing solution, also contains a known number of control particles, treated so as not to lyse in the presence of the hemolysing solution and shaped and sized so as to stimulate human white blood cells. Methods for preparing this apparatus, using mixtures of adhesive liquids and beads, are also provided. Furthermore, methods of quantifying components in liquid samples using the apparatus described above are provided. Generally, the methods consist of either placing a liquid sample on the adhesive matrix of the microscope slide and mixing it so that the matrix dissolves in the sample, or placing a liquid sample on an unprepared microscope slide and stirring it with the stirring rod having the adhesive   matrix over one tip so that at least a portion of the adhesive matrix dissolves therein. A cover slip is then placed over the sample so that the cover slip rests on the beads and is spaced from the slide by a known distance determined by the diameter of the beads. The counting chamber provided thereby is placed under a microscope and the components in a known volume of sample are counted, wherein the known volume is determined by measuring the viewing area of the microscope and multiplying the viewing area by the distance between the slide and cover slip as determined by the diameter of the beads.

Abstract: Disclosed is a printing device with a data memory for efficiently storing character code data and other attribute data in a limited memory region. If a character code of a print data input from the keyboard is a space code, the print data is nullified, and a pitch data corresponding to the space code is added to the pitch data corresponding to the character code previously stored in a correction memory. Namely, the data are compressed. Since only the print data excepting the space code data is stored in the memory, the limited memory region is efficiently used.
