Abstract: 1454383 Cutting apparatus ARMSTRONG CORK CO 28 Nov 1973 [29 Nov 1972] 55204/73 Heading B4B [Also in Division B8R] An apparatus for forming carpet tiles comprises a feed structure 6 for positioning a sheet 2 of carpet upon a needle board conveyer means 8, conveyer means 16 for passing the needle board and sheet past a number of cutting discs 14 to slit the sheet into a number of strips and further conveyer means 20 for moving the board and sheet past a second set of cutting discs 22 to thereby divide the sheet into squares. The needle board is pulled past the cutting discs 14 by means of a lug on a chain 19 engaging the rear edge of the board until the latter reaches a ball-type transfer conveyer 18; the board is then moved manually until a lug on a second chain 21 engages the board to thereby move the latter and carpet sheet past the second set of cutting discs 22. The separated carpet tiles are then removed from the board which is returned to the starting point via a further ball conveyer 24 and other transfer means (not shown). The uncut sheet is fed on to the needle board by means of a shoot 4, Fig. 2, which is supported by a pivotable member 30. The leading end of the shoot is formed with fingers 36 so that by pivoting the member 30 by a compressed-air actuated means the leading end can be lowered into the needle board; as the needle board is moved by the chain 19, the carpet sheet is drawn from the shoot. The lowering of the shoot is controlled by a switch 40 actuated by movement of the needle board.

Title: Method and apparatus for analyzing microscopic particles
IPC: A61B5/145
Filed: 1972-12-07
Abstract: 1404628 Photo-electric particle analyzers COULTER ELECTRONICS Inc 7 Dec 1972 56446/72 Heading G1A Microscopic particles are analyzed by illuminating them with a sequence of pulses of EM radiation and separately scanning the image produced by each pulse to produce output data, the system being arranged so that data relating to different parameters of the particules are obtained by successive pulses. In a first embodiment, Fig. 1, three flash tubes 22, 24, 26 are arranged with a pair of dichroic mirrors 32, 34 to trans-illuminate particles carried on a microscope slide 16. The image magnified by the microscope 10 is viewed by a vidicon camera 12 which is preferably of the storage type. The target of the vidicon is scanned with a raster and is provided with vertical blanking pulses which are also applied via shaping circuitry to a ring counter which triggers the flash tubes in turn, Fig. 3 (not shown). This results in the sample being illuminated by a sequence of flashes of red, blue and green light each flash occuring in the blanking intervals between successive scans. The output of the vidicon and signals from the scanning circuits and flash tube control circuits are applied to a signal processor, which is provided with a store to enable the parameters of the particles to be determined and hence the particles to be identified and counted. Instead of trans-illumination the flash tubes may be arranged for reflective illumination. The light from the flash tubes may be individually filtered, the dichroic mirrors being replaced by half silvered mirrors. A single flash tube may be used together with a synchronously rotated filtered wheel placed in front of the camera. The illumination may also consist of IR or UV radiation. The slide may be moved continuously or stepwise during the measurements. In a specific application the sample is blood stained with Wright's stain. With green light the white cell nuclei and platelets stand out in sharp contrast and can be differential by, their sizes and shapes. With blue light the white cell nuclei cannot be distinguished from the cytoplasm, the white and red cells being equally opaque while the platelets are transparent. These parameters can be utilized to determine the numbers of white cells, red cells and platelets in the sample.

When handle 26 is pulled forwardly the rotation of shaft 28 is transferred to shaft 60 provided a coin has been deposited to form a mechanical link between bearings 44, 46 and hence between rods 50 and 56. After the deposited coin has moved below an abutment 80, it is ejected from its position between bearings 44, 46 and the consequent release of rod 56 and its bearing 46 allows rotation of shaft 60 in the opposite direction under the action of a spring 62 and free-wheel spinning of reels 68, 70 as segments  72, 74 engage, then disengage, gear-wheels 76, 78. During the initial rotation of shaft 60, an arm 84 fixed thereto, Fig. 5, is withdrawn from interaction with cams 88 and 86, Fig. 7, which face one another and are fixed to reels 70 and 68 respectively, to free the reels. Arm 84 is held in a retracted position by the engagement of a rod 97, Figs. 4 and 5, with protrusions 100 of a pivoted release mechanism 92. To stop the reels, button 90 on mechanism 92 is pressed to release rod 97 and allow arm 84 to swing into engagement with cams 86, 88 under the action of spring 62, the precise stopped position of the reels depending on the relative positions of cams 86, 88. Cam 88, Fig. 5, has recesses 89, 91 and should one of these be engaged by arm 84 and be simultaneously aligned with a recess 93 of cam 86, Fig. 7, a pay-out is made proportional to the depth of recess 93. As shown, three depths of recess 93 are provided giving three pivoted pay-out positions of an elbow 102 attached to arm 84. Elbow 102 engages a dispensing wheel 38, Fig. 6, having a coin pocket 40 provided with fulcrum points 108, 110, so that one, two or three coins are dispensed depending on which pay-out position is reached, if any, by elbow 102. Coins are supplied to pocket 40 via storage compartment 34 and coins arrive in the latter either after release from bearings 44, 46 or by deposit in an opening 22.

Filed: 1970-12-18
Abstract: 1333603 Assembly force fits TELETYPE CORP 18 Dec 1970 [29 Dec 1969] 60224/70 Heading B3U A tool for inserting a workpiece 16 into a receiving member 38 comprises a member 11 for pushing the workpiece into the receiving member, means for sensing a movement of the workpiece indicating that a minimum withdrawal strength of the workpiece has not been met when the workpiece is pushed into the receiving member, and means for preventing further insertion of the workpiece into the receiving member upon the sensing of said movement. In operation a force is applied to the shaft 11 by sliding a housing 21 to the left, as seen in Fig. 1, so as to disengage the housing from a surface 39 of a blocking member 33 and compress a spring 26 between a slidable spacer 24 and a spacer 13. The end 22 of the housing 21 and the spacer 24 are thus temporarily aligned with a slot 36 in the member 33. If the workpiece has not moved appreciably into the member 38, the spacer 13 will still engage with a surface 41 of the member 33 and so hold the latter against the force exerted by a spring 34. Continued movement of the housing 21 moves the spacer 24 so that it engages a surface 43 of the member 33 and abuts a sleeve 14 of the spacer 13. There is then a direct drive between the force applied to the housing 21 and the shaft 11, and the workpiece 16 is driven into the member 38. If there is an unacceptable press fit the workpiece moves into the member 38 before the spacer 24 has engaged with the surface 43. Thus the spacer 13 disengages from surface 41 before the spacer 24 engages 43 so that the blocking member 33 moves upwardly because of spring 34 to accommodate the spacer 24 and end 22 in the slot 36, and the spacer 13 in the slot 37. Further movement of the spacer 24 is stopped and a solenoid 47 is operated to withdraw blocking member 33 and allow the retraction of spacer 24 and housing 21 to their initial position. The force exerted on the workpiece in response to a particular force exerted on the shaft 11 by the spacer 13 may be altered by the engagement of a drag screw 40 with the shaft 11.
