Title: Fabric density calculating means
IPC: G06M1/08
Filed: 1962-11-30
Abstract: 968,140. Inspecting fabrics; knitting; weaving SINGER-SUPREME CO. Inc. Nov. 30, 1962 [Dec. 19, 1961], No. 45504/62. Headings D1C, D1E and D1S. Means for indicating the density of a fabric during knitting, weaving &c.,is shown applied to a knitting machine and comprises means for measuring the number of courses in a measured length of the fabric and a computing device displaying indicia representing the density of courses in the said measure length. The number of courses is derived from actuations of a switch 46, Fig. 1. by a lug 44 on a bracket 29 of the machine cylinder 17. The measured length of the fabric F is obtained from the rotation of a spiked wheel 32 engaged therewith and a chain 35 having a lug 37 which actuates a switch 40. The computing device obtained from the rotation of a spiked wheel 32 engaged therewith and a chain 35 having a lug 37 which actuates a switch 40. The computing device comprises, Figs. 2 and 3, a first ratchet wheel 54 which is stepped clockwise against a spring by a pawl 70 actuated by a solenoid 74 under control of the switch 46, a pawl 77 preventing return movement. A lug 64 on wheel 54 engages a pin 65 on a second co-axial toothed wheel 58 to carry it round with the first wheel 54, a pawl 81 preventing return movement thereof This second wheel 58 has secured to it an indicating wheel 55 with indicia 57 upon it which are visible through a window 90 which are indicative of the density of the fabric. The pawls 81, 77 holding the wheels 58 and 54 respectively are released in turn by a solenoid 92 when momentarily energized by switch 40 being actuated by lug 37 of chain 35. Thus both wheels 54 and 58 together with indicating wheel 55 are first stepped round together by pawl 70 until, after a measured length of fabric has passed, the switch 40 is momentarily actuated. A solenoid 92 is thereby actuated to first release pawl 81 from wheel 58 and then on de-energization to re-engage pawl 81 but release pawl 77 from wheel 54 by engaging a link 96 thereon. The wheel 54 returns to its original position under spring pressure leaving wheel 58 and indicating wheel 55 in a set position showing a certain value of the indicia 57. The stepped operation of wheel 54 is then repeated by pawl 70 when the lug 64 may just abut pin 65 on wheel 58 again or if the density of the fabric has increased may move wheel 58 and indicating wheel 55 round further If the density has decreased lug 64 will not reach pin 65 and on release of pawl 81 wheel 58 will move back until pin 65 abuts lug 64 to give a new reading on wheel 55. A lever 102 resets link 96 of pawl 77 upon the first stroke of pawl 70.

Filed: 1974-10-25
Abstract: 1482548 Fuel injection pumps ROBERT BOSCH GmbH 25 Oct 1974 [26 Oct 1973] 46185/74 Heading F1A In a fuel injection pump having a rotatable and reciprocable piston 4 and an annular valve 17 which controls a relief passage 15 from the working chamber 6, the valve 17 also controls a further relief passage having two portions 35, 34 and 29 which are only in communication during a portion of each delivery stroke of the piston. The first portion comprises a transverse passage 35 in the piston branched from the passage 15 and in communication with an internal groove 34 in a cylinder liner 3'. In operation delivery is interrupted when the discharge port 30 of the second portion 29 becomes no longer covered by the valve 17 and the inlet port 31 of the portion 29 still communicates with the groove 34. As soon as this communication is broken delivery re-commences until the relief passage 15 becomes uncovered. If the valve 17 is moved downwards to decrease the quantity injected, the stroke b which occurs before the discharge port 30 is uncovered decreases and the main portion of the delivery occurs after the two passage portions are disconnected. The effect is therefore to delay or retard injection with decreasing load. Grooves 7 and 19 control the fuel entry and distribution of the delivery to outlets 20, respectively. In a second embodiment the first portion 34, 35 is replaced by a longitudinal passage (28) in the liner 3', the passage being arranged to register with the inlet port 31 via an annular groove (37) in the piston.

Abstract: 1,140,851. Read-only stores. ELLIOTT BROS. (LONDON) Ltd. 11 Feb., 1966 [17 Nov., 1964], No. 46682/64. Heading G4A. [Also in Divisions H1 and H3] Data in a read-only store is represented by magnetized portions of a magnetizable sheet 1, each at the intersection of a looped conductor 3a and a doubled magnetic and at least in part electrically conductive strip 2a, and may be read out by passing a saturating current pulse through a strip 2a, so that magnetic flux from the magnetized areas of sheet 1 adjacent to the strip is no longer diverted by it, but passes perpendicularly through it to link with conductors 3a and so produce outputs in them. A pulse in a strip 2a causes an emf. pulse of one polarity at its onset and another of opposite polarity at its onset and another of opposite polarity at its decay to appear across each conductor 3a which has a magnetized portion of shear 1 adjacent to its intersection with the strip. Insulating and supporting layers 2, 3, 6 may be placed between and adjacent to the conductors, and high-permeability, low-remanence sheets 4, 5 provided to close flux paths. Sheet 1 may be an insulating body with localized and/or distributed magnetic properties, or contain a plurality of magnetic members. Magnetically conductive material may be included in it between data storage points to provide easy flux return paths. Conducting or non-conducting magnetic material strips may be included in strip 3 between conductors 3a, as may a layer of low-remanence, highpermeability material for flux closure. The conductors 3a may have a plurality of turns, or be made with side-by-side loops in different directions. Sheet 1 may be removable and the data stored in it be exchanged by replacing it by a similar sheet, the sheets not in use being stored. Strips 2a may be composed of an electrical conductor surrounded by and insulated from magnetic material, or be composed of a number of magnetic conductors connected in parallel or in series or series-parallel. In this case the cores of the conductors remain unsaturated magnetically, apart from saturation imposed from outside them. They may be used for data storage in place of sheet 1, which is then omitted.
