Title: Thread cutting device for button holes and similar sewing machines
IPC: D05B65/00
Filed: 1934-09-27
Abstract: 423,492. Sewing-machines. DURKOPPWERKE AKT. - GES., 2, Nikolaus Durkoppstrasse, Bielefeld, Germany. Sept. 27, 1934, No. 27754. Convention date, Sept. 30, 1933. [Class 112] The thread cutters and thread-end holders of a buttonhole or like sewing-machine are freely mounted on an inclined guide at one end and pivotally supported at the other end, so that the cutting member performs a downwardly inclined forward movement when actuated. The device is removable. The base plate 1 of the device is removably mounted on a bracket 5 by a strap 2 suspended between pointed screws 3, 4. The front end rests on an inclined guide 6. The device is actuated by a pedal &c. acting on a chain 7. On pulling the chain, an arm 11 is swung in the direction of the arrow x, Fig. 2, by levers 8, 10. A roller 12 presses forward a plate 13 sliding on the plate 1. The plate 13 is guided by pins in inclined slots 16, 17. A plate 18 slidable on the plate 13 is shifted at the same time until its nose 19 comes into contact with an abutment 20 on the base plate 5, whereupon the plate 13 continues its forward movement alone. The plate 18 carries a strap 22 in which is mounted the axis 23 of the cutting members 28, 28<1>, 24. The tail of the cutter 24 is pivoted to a strap 21 moving with the plate 13 so that as the plate 13 continues to move, the plate 18 being stopped, the cutter 24 is rotated round the pivot 23, its cutting edge 26 approaching the clamping spring 27 and cutting edge 27<1> of the two-part cutter 28, 28<1>. When the swing of the cutter 24 is complete, the thread is severed and its end clamped on the upper edge of the inclined surface 29 of the edge 26. After cutting, the cutting members are returned by a spring 34, a pawl 36 being urged by a spring 35 to lock the plate 13. The cutting edges remain closed to hold the thread end till a few stitches have been made in the next buttonhole. The nose 38 of a lever 40 engaging the presser 39 then swings the pawl 36 out of its notch 41 and the device swings back into its inoperative position:

Title: Improvements in or relating to the automatic charging of secondary batteries
IPC: H02J7/12
Filed: 1939-10-13
Abstract: 535,702. Non-contact-making relays. STANDARD TELEPHONES & CABLES, Ltd. (Nys, L. J. G., Ballet, J. J. H., and Meeuws, V. C. J.) Oct. 13, 1939, No. 27850. [Class 40 (iv)] [Also in Group XXXV] A battery 1 is connected in circuit with a constant opposing potential, obtained for example from a tap 9 in a potentiometer 5 supplied through a constant voltage arrangement by transformers, the saturating winding of a choking coil SCR and a rectifier 3 so that a saturating current will only occur in the circuit when the battery volts have fallen to a predetermined minimum. The AC winding and the choke is in one of two normally balanced circuits supplying opposed coils of a relay 6 whereby contacts 7, 8 are closed to apply a charging source to the battery. A higher voltage (tap 10) is then connected with the saturating winding to determine the voltage at which charging shall be stopped by the cessation of saturating current. In a modification, two saturating circuits including different potentiometer voltages co-operate with two chokes and two balanced relays to supply charging current at two rates and in a further modification a single choke, progressively saturated as the battery volts fall, operates through a second saturable choke to operate successively two balanced relays controlling different charge rates. The battery may be connected alone to the saturating winding through a bridge circuit BC, Fig. 4, comprising non-linear resistances so that at a given voltage the circuit is balanced and the winding SCR 1  not energized. When the battery volts fall below this value the rising current Io in the choke and relay winding 62 is accompanied by a rise in current in a reaction winding SCR  2  accentuating the saturation whereby the relay is operated; the normal excitation due to winding SCR  2  is balanced by current in a winding SCR  3 . The reaction is not effective when the bridge is unbalanced in the opposite sense. The Specification describes the application of this reaction principle to the arrangements previously described.

Title: Improvements in or relating to straight bar knitting machines and variable control means primarily applicable thereto
Inventor: BLOOD RAYMOND
IPC: D04B15/64
Filed: 1957-09-11
Abstract: 897,763. Knitting-machines. COTTON Ltd., WILLIAM. Sept. 4, 1958 [Sept. 11, 1957], No. 28595/57. Class 74 (2). [Also in Group XXIV] In adjusting the screw 39 of the draw lever 24 to vary the draw bar motion in relation to the periodic adjustment of constant amount of the carrier end stops of a straight-bar machine, the effect of the varying leverage of the lever 24 is compensated for by gradually increasing or decreasing the amount of turn given to the screw so that the adjustments in the movement of the draw bar are also of constant amount whereby the lead of the thread carriers over the slurcocks remains constant. This variable adjustment of the screw 39 which is effected from the constant adjustment of the carrier end stops is achieved through control mechanism 45 comprising an input shaft 2 which is coupled to and rotated with the carrier end stops so that it also receives periodic adjustment of constant amount. Mounted on the shaft 2 is a member 3 of near conical formation haivng a helically grooved surface on which is wrapped a sprocket chain 5 rigidly secured at each end so that it extends around the member 3 in a helical formation. A shaft 12 mounted in the end of the housing of the mechanism freely supports a bracket 11 carrying at its outer end a sprocket 8 which engages with the chain 5 on the member 3. The sprocket 8 is coupled with a sprocket 9 and this latter sprocket 9 is connected by a chain 13 to a further sprocket 14 mounted on and coupled by a splined connection to the shaft 12. The bracket 11 is slidable along the shaft 12 and is moved together with the sprocket 14 along it as the member 3 is rotated. This slidable movement of the bracket 11 is imparted by a screw 18, of the same pitch as the helical surface of the member 3, traversing a nut having a lug 17a engaging between the arms of a fork 11a formed on the bracket 11. The shaft 18 is driven by chain and sprocket gearing 19, 20 from the shaft 2 so that the sprocket 8 engages with and traverses the helically wound chain over the varying diameter of the member 3 such that its rotation, imparted by the rotation of member 3, and that of the shaft 12 is varied as it moves along the member 3. The bracket 11 carries a roller 15 which engages with a cam surface 16 on the top of the housing as the bracket is moved along the shaft 12 so as to hold the sprocket 8 in engagement with the chain 5. The shaft 12 is coupled to the draw lever screw 39 to make the necessary adjustments. As illustrated in Fig. 7 similar control mechanism 46 is provided for adjusting a screw 40 of a lever 28 associated with the draw lever 24, the screws 39 and 40 being coupled together by a link 27 carrying the nuts 41, 42 which adjust the position of the link 27 when the screws are rotated and thereby control the movement of the draw bar from the draw cam 33 operating the levers through the truck lever 31 and link 30.

Title: Process for the upgrading of hydrocarbons by hydrogendonor diluent cracking
IPC: C10G47/34
Filed: 1954-10-05
Abstract: <PICT:0760546/III/1> In processes of the kind in which heavy mineral oils are converted into gasoline by cracking them in admixture with a diluent oil which acts as hydrogen donor to the heavy oil, the products of the cracking reaction are fractionated to isolate a middle fraction which is solvent extracted to obtain an aromatic fraction which is then partially hydrogenated to produce the hydrogen donor diluent oil; the fraction denuded of aromatic constituents is then cracked catalytically.  The aromatic fraction may be obtained by extraction with phenol, sulphur dioxide, antimony trichloride or furfural.  Feed supplied through line 10 is mixed with the hydrogen donor fraction supplied through line 11 and the mixture is passed through a heater 1 to a digester 2 where temperatures of 500-1,200F., pressures of 100-3,000 p.s.i.g. and residence time of 0.1-5.0 V/V/hr. are employed.  The cracked products pass to fractionator 3 where separation is effected into gaseous products removed through line 14, gas oil through line 15, a suitable diluent cut through line 16 and bottoms through line 17.  The diluent cut is fed through line 16a (with the addition of an externally supplied cut fed through line 31b if desired) and to the extraction column 4 where the aromatic constituents are extracted by treatment with phenol supplied through line 20 the extract and solvent passing to the stripper 5 where the phenol is recovered and recycled to line 20 the enriched aromatic cut passing to the hydrogenator 6 and the hydrogenated product being recycled through line 24 to the line 11.  The raffinate is fed through line 19 to stripper 7 and the stripped aromatic poor oil is removed as a product of the process through line 29.  The bottoms from the fractionator 3 may (a) be purged in part through line 28 (b) recycled through line 25 to mix with the crude feed (c) - (e) fed through line 18 as the diluent cut where no special cut is taken off through line 16 (d) be sent direct to the hydrogenator 6.  The diluent cut can be similarly treated.
