Title: Improvements in method and apparatus for shaping tyre casings
IPC: B29D30/36
Filed: 1952-08-29
Abstract: 717,221. Shaping tyre casings. PIRELLI SOC. PER AZIONI. Aug. 29, 1952 [Oct. 25 1951], No. 21829/52. Class 87 (2) A tyre casing is shaped from a pulley band by means of a hollow expansible core C which is attached to a suction and pressure head for insertion and removal from the casing and is removed, together with the casing, from the suction &c. head for performance of the intermediate vulcanization step. The core C has a central aperture F which is fitted over the suction head, Fig. 3. The suction head comprises a hydraulically-movable piston 15 having an upper cylindrical extension 20 which is surrounded by a cylindrical elastic diaphragm 21. This diaphragm is attached at its upper edge to the cylinder 20 and at its lower edge to the frame B of the machine. When the piston 15 is lowered from its original upper position (not shown) the diaphragm 21 bulges to form a flange which yieldingly holds the core C in position. The upper surface 43 of the core rests on a head 34 mounted for limited vertical movement in the upper end of a central stem 8 so that it may rise and fall with the cylinder 20 upon which it rests. To distort the core the stem 8 with the head 34 is raised by a hydraulic cylinder 10 and suction is applied to the core C via the inlet 38. The pulley-band may now be placed over the distorted core, Fig. 5 (not shown), with its lower bead engaging a step 11 in the platen 1. The upper platen 2 is then lowered until the step 11<1> engages the upper bead. Further downward movement of the upper platen 2 with application of fluid pressure to the core C accomplishes the shaping of the casing D, Fig. 6 (not shown). After the core has been exhausted of fluid, the piston 15 is raised to eliminate the flange 25 and the casing, together with the core, is removed for vulcanization. To remove the core from the vulcanized casing it is once more fixed to the suction head, Fig. 8, and distorted in the manner already described.

Title: Automated blood cell identification
IPC: A61B5/145
Filed: 1974-05-16
Abstract: 1465162 Analysing tissue photo-electrically CORNING GLASS WORKS 16 May 1974 [21 May 1974] 21929/74 Heading G1A Apparatus for identifying an eosinophil blood cell, i.e. a leukocyte whose nuclear granules stain red when tinged with Wright's stain, comprises: a high-resolution microscope disposable to form an image of a blood cell carried on a smeared slide; beam-splitting means and filters for producing two differently-coloured images; a detector for converting points on each image into electrical signals; an A/D converter producing coded signals representing the electrical signals; means for generating optical-density histograms; means for comparing respective portions of the histograms and for signalling when one histogram portion contains more points than the other. Histograms of yellow and blue optical densities in an eosinophil cell are given in Figs. 2A and 2B respectively. Both curves have minima at Ty and TB respectively corresponding to a background density in the cytoplasm and nucleus of a non-staining cell; but the summed counts at all densities above these minima are found to show a marked excess of blue-dense over yellow-dense points, the ratio being 1À5-2À5 for eosinophils, in contrast to other cells where the ratio is about 0À9-1À2. A high-resolution microscope 11, Fig. 1 is automatically controlled 13, 14, 15, to acquire and focus on a blood cell on a smeared slide 12. Optics 16, a beam-splitter 17, 18 and filters 19, 20, produce respectively yellow and blue images on the screen of a vidicon tube 21 which generates electric charges analogous to the brightnesses of successive points on the two images. An A/D converter 22 and memory 23 produce and store signals representing the optical density point by point. A six-bit signal for each point in turn is retrieved from the memory 23 and passed to a computer 24, of which the input stages are identical registers 25, Fig. 3A and (26), Fig. 3B (not shown) for yellow and blue signals respectively. The sixbit yellow signal is fed simultaneously to all of 64 decoders 27 ... 29, each of which is set to emit a pulse if the optical density is of a specific magnitude. As the memory is scanned the pulses emitted by the decoders 27 ... 29 are stored in 64 counters which collectively will contain, at the end of a scan, a histogram n 1  ... n 64  of the yellowdense points. A comparator 37 identifies the density T Y  having the minimum count n min  and passes all counts at this density and above to an adder 38. Similar apparatus is illustrated in (Fig. 3B) for operating on the blue densities. The ouputs Ny, NB from the adders 38 Fig. 3A, (39) (Fig. 3B), are converted to a ratio N B /N Y  in a divider 40 Fig. 3A. A comparator 41 signals the presence of an eosinophil cell if this ratio exceeds a threshold set at 1À5.

Title: Machine for treating pulp material
IPC: D21D1/24
Filed: 1965-05-25
Abstract: In a cylindrical pulp refiner wherein the opposed attritioning surfaces of the rotor and stator have bars for treating the fibres of the pulp as the pulp passes between the attritioning surfaces, each of the bars on both attritioning surfaces extends in a single plane but with the planes of the bars on one of the surfaces intersecting the planes of the bars on the other of the surfaces at the same relative angularity of between 18 degrees and 38 degrees at corresponding crossing points and the side faces of each of the bars on one of the surfaces being inclined in one direction relative to the adjacent portion of the surface at the base of the bar at one end of the bar and being inclined in the opposite direction relative to the adjacent portion of the surface at the base of the bar at the opposite end of the bar whereby the fibres of the pulp passing between the attritioning surfaces will be subjected to combined cutting and brushing actions with the proportionate amount of cutting being greatest at one end of the attritioning surfaces and least at the opposite end of the attritioning surfaces.  In one example, the bars on the attritioning surface of the rotor extend in radial planes intersecting on the axis of the rotor and the planes of the bars on the attritioning surface of the stator intersect at points on the common axis of the rotor and stator.  The side faces of the bars on the stator are inclined against the direction of rotation of the rotor at one end of the stator and inclined in the direction of rotation of the rotor at the opposite end of the stator.  In alternative constructions, the planes of the bars on the attritioning surface of the rotor or on the attritioning surfaces of both the rotor and stator may intersect at points on the common axis of the rotor and stator.
