IPC: B41J33/516
Filed: 1957-12-20
Abstract: 845,732. Ink-ribbon mechanism. INTERNATIONAL COMPUTERS & TABULATORS Ltd Nov. 10, 1958 [Dec. 20, 1957], No. 39711/57. Class 100(4) Reversing mechanism. An automatic ribbon reversing mechanism of the kind having a feed pawl 10 for each ratchet 9 of each ribbon spool spindle 2, 2A comprises a rockable support 12, 12A for each feed pawl 10, 10a actuated by arms 18, 18A, a connecting link 22; an operating member 31 having a stroke of constant length; and a spring-loaded changeover device coupling the link 22 and member 31; this device is arranged to normally transmit movement to rock the arms 18, 18A and effect feeding movement of the active feed pawl and when the spring-loading is exceeded by the load applied to the link 31 the device amplifies the movement of the link 31 whereby, in conjunction with feed pawl trip cams 20, changes over the active and machine feed pawls. As shown in Fig. 1 the right-hand spool 3A is being driven by active pawl 10A through parts 12A, 18A, 22 from a driven link 23 pivoted to a crank plate 24 pivoted at 25 to a bell crank lever 26. This, in turn, is pivoted at 27 to the frames and is urged by a spring 28 against either stop 29 or 30. The crank plate 24 has a change-over pin 39 extending into an opening formed in a change-over arm 40 and when spool 3A is being driven it works against guide face 42. When the other spool is exhausted the load required to drive the spool is increased and the pull of driver link 23 exceeds the loading of spring 28, this exerts torque on the crank lever 26 which moves away from the stop 29. Pin 39 moves out of engagement with the guide face 42, arm 40 moves counterclockwise and pin 39 engages recess 44 (see Fig. 9). The return movement of operating member 31 pivots the crank plate 24, and lever 26 moves against stop 30. On next operating movement the crank plate 24 is first rocked about pin 39 and causes, through link 23, the connecting link to be given a greater than normal movement to make trip cams 20A, 20 disengage driving pawl 10A and engage pawl 10 respectively. Spool brakes. Spring urged brake plates 6, 6A, Fig. 3 engage the rims of the spools. Detachable structure. The ribbon-feeding apparatus is constructed as a unit which can be fitted to or removed from a machine as an entity.

Title: Liquid applicator
IPC: A45D34/00

Abstract: 880,486. Diaphragm pumps; raising liquids. HEDLEY & CO. Ltd., THOMAS. Dec. 10, 1958 [Dec. 11, 1957], No. 39890/58. Classes 102(1) and 102(2). A liquid applicator comprises an apertured transverse wall 21, extending across the opening of a liquid container, and a diaphragm member 25, provided with slit like openings 26, forming a variable volume space 30 which is greater in volume than the bore of a dip tube 24 extending from the aperture to the bottom of the container. On fixing the applicator to the container the air in the container is compressed and liquid is forced in the space 30 where there will be a bubble of air 35. The member 25 is applied to the surface to receive the liquid and is rubbed over this surface causing the diaphragm to be depressed or released and the apertures to be covered or uncovered. Thus liquid is continually forced through the openings and air also flows through the openings into the reservoir and is forced through the dip tube 24 causing an increase in pressure in the space 34 of the container which forces further liquid in to the reservoir. The diaphragm may be received in a circular slot 28 (as shown) or the applicator may be moulded as a single piece which receives the transverse wall The diaphragm is preferably provided with ribs so that it readily expands to its natural shape.

Abstract: 1458973 Automatic control GEC-ELLIOTT AUTOMATION Ltd 23 Aug 1974 [23 Aug 1973] 40000/73 Heading G3N The rolling of strip material in a rolling mill is automatically controlled in response to calculations deriving the ideal roll force on a stand which will give the nose of the strip material a shape threadable into a subsequent stand or within predetermined limits of badness. As shown, a digital computer 22 is programmed to provide, or is fed from punched-tape, a rolling schedule in ablock 100. The schedule is fed to a calculator block 101, in which the roll force occurring on the nose of a strip is determined, and to a calculator block 102 which determines the thermal camber to be used in determining the zero shape roll force in a calculator block 103. The outputs of blocks 101, 103 are compared in a comparator 104 and the output used to calculate the jack force settings and gauge changes in a block 105 which is then used by a programmer 106 to apply these settings to the mill during threading and subsequently to remove them as the strip passes through the mill. The calculations to be carried out in the blocks 101-105 are set out in detail in the Specification.

Abstract: 1483963 Object comparison WESTING- HOUSE ELECTRIC CORP 6 Oct 1975 [15 Oct 1974] 40773/75 Heading H4F Selected portions of the video signal of an object to be evaluated are compared 12 with the corresponding selected portions of a stored 11 video signal of a model object, and any resulting difference signals are passed to threshold circuitry 20, 21 which generates an error signal whenever a difference signal exceeds a predetermined value for a predetermined time period. The portions, e.g. scan lines, of the video signals to be compared are selected by means of a programmed memory 14 which actuates a gate 15 to pass the difference signals from the selected portions to a video to pulse converter 20 having a predetermined threshold value, and then to a pulse discriminator 21 which only passes pulses above a predetermined width (i.e. time period) to an error display. The output of discriminator 21 may pass via additional circuitry (Fig. 3, not shown), including a shift register and decoding circuitry, which supplies a signal to the display only when an error signal is produced by the discriminator in a selected number (e.g. four) of adjacent scan lines.

Title: Method of and apparatus for handling cheese curd
IPC: A01J25/11
Filed: 1965-09-26
Abstract: Strips are cut from a block of cheese curd which is contained along a pair of opposed sides by a pair of parallel wall surfaces, by shifting the block relative to the wall surfaces so that a segment of the block projects, applying pressure to the exposed surfaces in a direction normal to the exposed surfaces, and severing a strip from the segment by means of a knife extending generally normal to the wall surfaces.  The block may be formed by depositing the curd in an open-topped receptacle wherein it is compacted, and the so formed block has one of its sides exposed by displacing one side wall of the receptacle, and then the block is shifted relative to the receptacle to expose a projecting segment.
