Filed: 1976-04-30
Abstract: 1505217 Workpiece guides PFAFF INDUSTRIEMASCHINEN GmbH 30 April 1976 [24 July 1975] 17695/76 Heading D1G A guiding device on a sewing machine with a feed dog (11), Fig. 3 (not shown) has spaced apart plates 16, 17; 59, 60 with a pressure point 27, 28 located laterally in front of the stitching point, their spacing being adjustable by members 34, 35 or 77 which are coupled with further members 36 or 87 which alter the pressure between the plates supplied by spring 45 or 85, there also being a guide 23 or 64 disposed at an acute angle to the sewing feed direction to guide the material edge. In Figs. 1 and 2 the spacing is varied by eccentrics 34, 35 while eccentric 36 alters the spring pressure. In Fig. 4 the spacing adjustment is by moving slider 77 whose inclined parts 80, 81 support the edge of upper plate 60. Spring 85 is carried by slider 77 and its end runs up wedge shaped member 87 which alters its pressure. Further pressure adjustment is possible by nuts 31, 72 acting on springs 30, 71 and by set screw 43 or 84 which acts on the leaf spring. Material W passing between the plates rotates about the pressure point while its edge is guided by the pins 24 or 64 and then pins 56, see Fig. 1, to align its edge with the sewing needle 7. A reinforcing material F passes beneath the lower plate so avoiding the guide pins and pressure point and its edge is trimmed by a knife 14.

Title: Improvements in or relating to endless track vehicles
IPC: B62D55/24
Filed: 1931-06-18
Abstract: 370,264. Endless-track vehicles. MARTINAGE, L., 46, Rue de Courcelles, Paris. June 18, 1931, No. 17738. Convention date, Feb. 26. Addition to 368,628. [Class 79 (i).] The endless track described in the parent Specification, which owed its rigidity in one direction under load to the relationship between the lengths of the track links and the spacing of the track pivots and of the loadsupporting rollers, is modified in that the track links, instead of being pivoted together are secured to a flexible band of metal, rubber, leather or other suitable material. In the construction shown overlapping links 1, 2 are secured by bolts 7 to a band or belt 3, tread shoes 5, 6 also being secured to the band by the same bolts. The load-supporting rollers 9 run on the upper faces of the links 1, 2 and the track is guided by means of angle or channel members 10 bolted at 11 to the track and having side faces which engage the inner faces of the rollers. The track may be driven by means of blocks 11a secured to the track by the bolts 11. The links 1, 2 are formed of metal of channel, T, angle or other suitable section.
Patent GB-866780-A (GB)
Title: Method of and means for coating surfaces by electro-deposition
IPC: B41M5/10
Filed: 1957-06-04
Abstract: 866,780. Coated paper; coated fabrics; seaming non-metallic sheet materials. COMMONWEALTH OF AUSTRALIA. June 4, 1957 [June 14, 1956; March 26, 1957], No. 17809/57. Drawings to Specification. Classes 42 (1), 96, and 140. [Also in Groups XVI, XX, XXIII and XXXVI]  A coherent deposit is formed on a surface by electrophoresis (see Group XXXVI) from a dispersion in an electrically-insulating carrier liquid of a particulate material coated as by ball-milling with a control agent which effects maintenance of a chosen surface charge when the particles are suspended in the carrier liquid. Welding plastics.-Sheets of plastic arranged on a conducting former are joined together by such an electrophoretic deposition process along the gaps between the sheets using the former as the electrode to which the particles migrate. A suitable dispersion comprises methyl methacrylate in chloroform. The surface to be coated may form one electrode in the coating bath or may be disposed between positive and negative electrodes. For webs a roller or narrow bar over which the web passes may form one electrode, the other being a spaced rod or knife edge. Successive coatings may be applied by passing a web continuously through two deposition baths in tandem. Coated paper.-Separate sheets or webs of electrophotographic paper (see Group XXXVI) is produced by electrophoretic deposition of a coating from a dispersion in carbon tetrachloride of a paste formed by ball-milling together an alkyd resin (control agent), zinc oxide, yellow litharge, and cobalt and manganese driers in toluene. A web of carbon paper is similarly produced by deposition of a coating from a dispersion in carbon tetrachloride of a ball-milled paste of an alkyd resin, gas black, nigrosine and castor oil. A web of coloured paper is produced by deposition of a glossy red coating from a dispersion in toluene of a ball-milled mixture of epoxy ester resin, Toluidine Red and cobalt naphthenate in xylol. Patterns may be formed including more than one colour of pigment particles in the dispersing liquid, by varying the speed of the rollers feeding the paper web through the deposition bath, thus varying the coating thickness and intensity of colour, and by the use of shaped electrodes or masks to control the coating deposit. Coated fabrics.-Webs of leather, fabrics of wool, cotton, silk or plastic, or plastic sheets are coated in a manner similar to that described for paper with the difference that if the web is not sufficiently conductive the back of the web is coated with a material which makes it at least partially conductive, e.g. gelatine or silver chloride. By passage through separate treatment baths an adhesive and a granular material may be deposited in succession.

Abstract: 958,751. Rolling. MORGAN CONSTRUCTION CO. May 9, 1962 [June 29, 1961], No. 17820/62. Heading B3M. [Also in Division B8] Bars 20 are cooled on a walking beam conveyer 46 and are aligned at their ends by rolls 8 so that they pass on to shuffle bars 22, 24 which are operated by eccentrics mounted on shaft 26 to convey bars 20 as shown till these are checked by a stop 51. When the operator wishes to feed bars 20 on to roller conveyer 42, he causes stop 51 to pivot clockwise to the position of Fig. 3. At the same time rollers 25, which support the right-hand ends of the shuffle bars, are caused by linkage 46 to move clockwise so as to raise said ends of the shuffle bars. The effect of both movements is to free the rods from stop 51 to discharge themselves on to the roller way till the linkage 51-46-25 is moved back to its original position.

Title: Improvements in and relating to electric circuit breakers
IPC: H01H71/50
Filed: 1936-06-27
Abstract: 455,204. Snap - action switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 27, 1936, No. 17923. Convention date, June 27, 1935. [Class 38 (v)] Springs, arrangement of.-A circuit breaker comprises a movable contactmember normally biassed to closed position and means manually operable to one position for striking the member a hammer blow to move it to open position against the bias, the manual means being operable to a second position to permit movement of the member to closed position according to the bias thereon. Current-responsive means strike the member a hammer blow to open it independently of the manually operable means on the occurrence of predetermined current conditions. The movable bridge-contact 22 of each pole is pressed by spring 23 into engagement with fixed contacts 16, 17 in cavities 11, 14 formed, respectively, in the base 10 and insulating block 13. These contacts in one pole, Fig. 2, are connected directly to terminals 20, 21, but in the other pole is inserted the heating coil of a fusible mass and ratchet arrangement 26. An insulating member 28 slidable in guides engages both bridge-members 22. The operating handle 40 is pivoted at 39 within the cut-away part 34 of a plate 31 which has a pair of inturned plates 35, 36, over which is fitted a hollow, rectangular operating link 37 pivotally engaging notches 38 in the plates 35, 36. A deadcentre spring 44 engages the link 37 and an abutment 43 on the handle 40, clockwise operation of which carries the abutment 43 through the hole in 37 and carries the spring 44 over the dead centre. The link 37 thereby moves over against the other limbs of plates 35, 36 and imparts a hammer blow to the shoulder 45 of member 28, so forcibly separating the contacts. On reverse rotation of the handle, the springs 22 reclose the contacts. Electrically-released switches.-The fusiblyretained ratchet 26 normally serves to retain a U-shaped trip member 46, the limbs of which are pivoted at 39 whereas the yoke supports a pair of fibre plates 47, which in turn support a latch part proper 48 for engaging the ratchet 26. When the latter is released on overload, a spring 50 anchored to part 48 draws the member 46 down and causes it to engage the part 52 of the slide 28, so imparting a hammer blow to open the contacts.. To reset the member 46, handle 40 is rotated from the position shown, whereby a part 42 thereon engages a part 53 on member 46. On returning the handle and link 37 to the position shown, the springs 23 close the contacts. A partition 54, Fig. 1, separates the heating coil of the fusible trip from the mechanism. Arc-rupturing devices.-The arc is confined in housings formed by the cavities in the members 10, 13, and member 28 moves through and closes an aperture in one wall of each housing during the opening movement.

Title: Computer system particularly for use in a fuel injection control system
IPC: F02D41/34
Filed: 1974-04-25
Abstract: 1439422 Automatic control of I C engines ROCKWELL INTERNATIONAL CORP 25 April 1974 [25 April 1973 (4)] 18202/74 Heading G3N [Also in Divisions Fl G4 and H3] In a fuel injection control system for an internal combustion engine, the width of pulse required to operate the fuel injectors is calculated, by a programmed digital computer 12, from digital values derived from parameter sensors 10 e.g. for pressure, temerature and position. The timing of the injection pulses is also variable in dependence on the operating speed range of the engine as indicated by one or more distributers 13. The system is generally reset by a switch 39, Fig. 4, when power is turned on as by an ignition switch. In operation a distributer 40 provides a pulse DIST at some point in each cycle of each cylinder and these pulses are synchronized with a clock signal C to produce pulses DP which are counted by a counter 23, the counter output REF identifying the cylinders in firing order sequence. A reset pulse RP is applied to counter 23 once in each complete engine cycle indicated by a further distributer signal IDENT. A timer 29 is advanced by the clock signal C in the interval between successive pulses DP and produces an output DFT from a detector 32 at a given delay from the start of each DP pulse interval. The timer count is also used to detect when the engine speed is below a predetermined (cranking) threshold and to determine the range of speeds within which the engine is operating - the latter being identified by the count attained in a counter 37 which is incremented to read successive speed range thresholds from a memory 36 unfil correspondence with the timer output is obtained. A further counter (SERVO), Fig. 5 (not shown) and comparator are used to detect when a change from one speed range to another occurs so as to inhibit the production of a FIRE pulse from a DP pulse or to insert an additional FIRE pulse between two successive DP pulses thereby adjusting the relative timing of the injectors by one DP pulse interval. The additional pulse is obtained from the timed signal DFT chosen to occur after the recovery period of an injector since the last DP pulse has elapsed. Fig. 6 shows the injector driver circuits. A de-coder 61 receives the difference between the REF and SERVO counts so as to distribute the FIRE pulses to the appropriate driver circuits via gates 66, 67. Each driver circuit includes a bi-stable 68, 69 the output Q of which enables counting up of a corresponding clock counter 63, 65 until a count equal to the computed pulse width value PW is obtained, the bi-stable then being reset to terminate the injection pulse.

Title: Improvements in or relating to machines for cutting or slicing grain or other granular materials
IPC: B02C9/02
Filed: 1924-07-30
Abstract: 226,129. Booth, V. July 30, 1924. Apparatus.-In a machine for cutting or slicing grain or other granular material and having a reciprocating receptacle into which the grain &c. is fed and through the perforated bottom of which it passes to the cutting and slicing means, a fixed transversely-extending part in the receptacle holds the grain stationary during the movement of the receptacle in one direction but allows it to move with the receptacle in the opposite direction, during which more grain is fed down in front of the transversely-extending part. As shown, the transversely-extending part is the rear wall of the hopper 2, Figs. 1 and 2, for feeding the grain into the reciprocating box 3 which has a central longitudinal partition 10 integral with or secured to the thin perforated bottom plate 8 of the box. A series of parallel, spaced, and double-edged cutters disposed transversely against the underside of the plate 8 is fixed to the edges of the rectangular frame 4 on which the box slides, and intermeduiate between the cutters is fixed a series of transverse members 13 the top surfaces of which are slightly lower than those of the cutters. The box is actuated by a rod 16 from an eccentric 21 on a driving-shaft 17, the stroke of the eccentric being greater than the spacing of the cutters 11. Longitudinal flanges 15 on the edges of the box work in grooved guides formed by plates 14 bolted to the frame 4. The grain is discharged from the hopper 2 on either side of the partition 10, through openings controlled by adjustable gates 20. The grains pass partly through the perforations in the plate 8 and rest on the transverse members 13 until they come under the action of the cutters 11. By adjusting the distance of the members 13 from the plate 8, as by means of packing-material or springs acting between the frame 4 and the members 13, the thickness of the cut grains can be varied.
