Title: Improved key operating machine
IPC: B41J7/60
Filed: 1960-11-18
Abstract: 899,368. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION, Nov. 18, 1960 [March 28, 1960], No. 39684/60. Class 100(4) A key operated machine such as the single element printer shown has key buttons 5 on key levers 6 and associated interposers 7 which may be integral therewith. The key levers and interposers are clamped to a bar 1 and depression of a key causes the interposer to flex and its finger portion 9 to pass through an opening 12 into holes 16, 17 in control tapes 15. This downward movement of the interposer 7 causes a reduced portion 27 to move down an opening 31 in a plate 30 to become engaged behind a shoulder 35 to hold the interposer latched if the key is released. Later in a cycle of operations thus initiated a cam 75 on a power shaft 50 acts through linkage to move a knock-off bar 38 to the left to disengage the interposer 7 from the shoulder 35 to allow it to return to an inoperative position and to its initial position when the key is released. In the single element printer shown flexing of an interposer 7 rocks a bail 26 to close contacts 28 to initiate a single cycle of the power shaft 50 by engaging a clutch 53. In the cycle a cam 70 releases the tapes 15 so that those having long holes 17 engaged by the finger 9 move under the action of springs 20 while those having holes 16 engaged are held stationary. Movement of the tapes 15 acts through selecting links 90-94 selectively engaged by a bail 140 actuated by cams 72, 73, as described in Specification 873,920, to rotate and tilt the print head 44 to select the desired character which is imprinted when a cam 71 actuates a lever 152. The cam 70 then acts to restore the tapes 15 to their original position while release of the finger 9 allows the interposer to rise to return the bail 26 to open the contacts 28 to disengage the clutch 53.

A closure for the upper ends of chromatography columns comprises a porous body, a capillary duct for admitting a liquid to one surface of the porous body and a packing means, fitting within the column and through which the capillary duct passes, for locating and retaining the porous body in a position which prevents the formation of a liquidfilled space above the charge in the column. In Fig. 3 (not shown), capillary (1) passes through closure (4) and terminates above porous body (5) which is made from layers of filter paper. In Fig. 4 (not shown) the duct through closure (4) (for example a rubber bung) leads to a conical recess (6) within the closure, the recess being filled with a porous body, the interface between the porous body and the column charge being convex to the charge. In Fig. 5, the centre portion of the porous filling is made less permeable by application of a plastics material 13. Packing device 4<SP>1</SP> is held between tubular nut 8 and plate 10; packing sleeve 14 is compressed between plates 10 and 15. In Fig. 6, plate 10 has upward and downward extensions, bottom nut 20 being screwed on its lower end and tube 11 to its upper end. Thread 19 may be truncated or may have a longitudinal groove (Fig. 9) to allow liquid fed in by capillary 1 to flow upwards to porous body 22, which may be of polyetetrafluorethylene or sintered glass. Fig. 7 is a version of the apparatus of Fig. 6 permitting its use in columns of varying diameters. Fig. 8 illustrates a clamping device for capillary (1) for use in narrow columns, for example 1.5 to 3 mm. i.d. In Fig. 10, sleeve 14 or I4<SP>1</SP> has circumferental grooves arranged so that they tend to open under the pressure below the closure.

Abstract: 1481996 Discharging hoppers TRW Inc 16 Sept 1974 [27 Sept 1973] 40283/74 Heading B8S Articles, e.g. fasteners, are fed in succession along a track 20 from a vibratory bowl (14) to a transfer station (22) at which each fastener in turn is pushed from the station (22) into a workpiece (26), Fig. 1 (not shown), the transfer station (22) including a passage 60 which is a continuation of the track 20 and a ram 24 disposed above the end of the passage 60 which is movable downwardly to push the leading fastener down into the workpiece, the leading fastener when in the station (22) being located on two spring loaded feet 68, Fig. 9, while the next fastener is also located on two such feet, each of the feet 68 being biased by a spring 78 such that their ends are located below the passage 60 to support a fastener thereon. The transfer station 22 also includes means for keeping the leading and the second or next fastener prior to the engagement, and during the engagement, of the ram 24 with the leading fastener, this means comprising a carrier 82, Fig. 6, having a pair of downwardly extending fingers 90 (only one shown in Fig. 6), and a pin 98 which extends through the upper portion of the carrier 82 rests near its ends on springs (102) which bias the carrier 82 upwardly, Fig. 12 (not shown). Downward movement of the ram 24 from its initial position of Fig. 5 (not shown) causes its engagement with a member 106 located on the carrier 82 such that the carrier 82 is moved vertically downwardly to its position shown in Fig. 6 until the pin 98 is prevented from further movement whereby the carrier 82 then rotates in a clockwise direction and its fingers 90 engage the second fastener thereby pushing the latter away from the path of the ram 24 as shown in Fig. 7 (not shown). This action of the carrier 82 results in the separation of the second fastener even when the latter is initially located partially over the leading fastener as shown in Fig. 6. The downwardly tapering punch member extending from the ram 24 extends through a cylindrical bore in each fastener. When the ram 24 is retracted the carrier 82 is rotated anticlockwise to its position shown in Fig. 6 by the action of a spring and plunger not numbered in Fig. 6, the carrier 82 then moving upwardly to its initial position under the action of the springs (102). If during the clockwise rotation of the carrier 82 to its position shown in Fig. 7 (not shown) the fingers 90 are unable to move due to jamming of fasteners in the passage 60, the member 106 on the carrier 82 is movable relative to the carrier 82 under the pressure of the ram 24 to prevent damage to the carrier 82.
