Title: Improvements in Machines for Printing Fabrics or the like.
Inventor: SAMUEL ANDRE
IPC: B41F17/00
Filed: 1919-03-20
Abstract: 126,946. Samuel, A. May 16, 1918, [Convention date]. Rotary machines.-A machine for printing on fabrics &c. in successive transverse strips is constructed with a printing mecha,- nism adapted to be traversed across the fabric on a frame which is movable along the fabric into position for successive printings. The printing mechanism is carried on a frame h supported through two plain rolls i<2>, i<3> and two combined plain and toothed rolls i, i<1> on bearers g, g<1> of a carriage d, which is supported through four combined plain and toothed rolls e on bearers b arranged on each side of the table ai over which the fabric p is laid. The bearers have rack portions engaging the toothed parts of the rolls, and the frame h is traversed for printing across the fabric by means of a crank n acting through sprocket wheels m<1>, m and a chain l, mounted on the carriage d, driving a wheel k on the shaft of the roll i<1>. After the return movement of the frame h, during which it is tilted to raise the printing mechanism clear of the fabric, the frame d is traversed along the table a by means of a crank f into position for the next printing, this traverse being controlled by means of adjusting nuts 16 on a screwed rod 12 on the carriage d and a sleeve 13 embracing the rod and clamped to the side of the table. The sleeve is set against the lug 11 and then clamped. and the traverse of the carriage is limited by the nuts 12 coming against the sleeve. The frame h carries an engraved roller o, driven by gearing 1, z, y from the rack g<1> on the bearer, and a trough s fitted with a fountain roll r and adjustable doctor t from which ink is transferred by a roll q to the engraved roller o. The roll q is carried in a jointed lever u mounted on a pivot v carried by, and arranged eccentrically to, the spindle of the rolls i<2>, i<3>, and when the movement of the frame h brings the lever against a stop 8, the frame is lifted to one end so that the printing mechanism is held clear of the fabric during the return movement of the frame and lowered when the lever comes against a stop 7 at the other side of the machine. The fountain roll is driven by gear 4, 3, 2 from the rack g<1> and drives the roll q through gear 5, 6. When the length on the latter is printed this is drawn forward and rolled up and the fresh surface is printed by a backward traverse of the frame d.

Title: Screw
IPC: F16B5/02
Filed: 1978-02-22
Abstract: The screw (1) is provided for the fixed connection of structural elements with a defined intermediate distance, without special spacer elements being necessary. The screw has a thicker threaded part (4) on the tool side and a thinner part (6) provided with a thread. The two parts (4, 6) are connected by a conical transition part (5) provided with a thread, and all these parts (4, 5, 6) are provided with a wood screw thread of the same lead. The transition part (5) is designed with two opposite grooves (10) for chips, the cutting edges of which grooves cut chips from the outer structural element. The material-displacing action of the thicker threaded part (4) is thus reduced, with the result that a clean bore edge is achieved without swelling of the material. <IMAGE>

Title: Improvements in or relating to data recording system for process control apparatus
IPC: G07C3/12
Filed: 1966-02-18
Abstract: 1,095,962. Recording apparatus. GENERAL ELECTRIC CO. Feb. 18, 1966 [March 31, 1965], No.7181/66. Heading G1J. In an industrial process sensors T, P feed data continuously to transducers RC1, RC2 to record magnetically on an endless belt B from which the records are erased by a magnet WO before passing the transducers RC1, RC2 again. When a failure in the process occurs an alarm device ALM provides a signal which by actuating a relay causes a circuit to be closed through a capacitor C<SP>2</SP>, relay pick-up winding RP and a direct current supply to provide a pulse to the winding RP thereby closing contacts CC1, CC2, CC3, and CC4. A printer PTR then prints data picked up by transducers RP1, RP2 to provide a permanent record in conventional coding of conditions sensed before and at the time of the failure. Meanwhile a condenser C<SP>1</SP> becomes charged and a vacuum tube V passes current to operate a relay RL, and break the holding circuit of winding RH, so that the CC contacts open and printing ceases. A sample of the data can be printed at any time by closing a switch S.

Title: Improvements in and connected with the separation of collcidal and other suspensionsfrom liquids
IPC: C10M175/00
Filed: 1931-03-09
Abstract: <PICT:0374915/III/1> <PICT:0374915/III/2> Used lubricating and similar oils are freed from suspended impurities, such as colloidal carbon, by forming a fine dispersion of water in the oil under pressure and separating the coagulated impurities.  Used oil passes through an inlet 4 and is forced by a pump 5 into a vessel 7 in which it is heated to about 230 DEG  F.  The hot oil passes through a pipe 10 to a centrifuge 1 in which it is agitated with a small amount of hot water or steam admitted through pipes 15 and 11 from a heated tank 12.  The mixture of water and oil is discharged through an outlet 1<1> into a time-lag tank 2 containing baffles, in which coagulation proceeds, preferably with the aid of an electric field. The mixture then passes into a centrifuge 3, to which a trickle of water is supplied through a pipe 16.  Purified oil is discharged through an outlet 17, and the separated water and impurities pass through an outlet 18 into the tank 12, containing baffles.  The supernatant layer of impurities is drawn off from a trough 19.  The centrifuges 1, 3 may be combined in a unit in which the dispersion is formed at the centre of a rotating drum from which it is discharged against a pile of conical discs mounted therein.  In a preferred form of the centrifuge 3, a preliminary separating space is provided adjacent the central inlet, by mounting an annular ring baffle 44, Fig. 3, between the flat bottom of the bowl 41 and the lowermost cone 42, so that the outer edge of the baffle extends into the water line, and the inner edge is just outside the oil line.  The mixture of oil and water descends through the inlet 40 to the separating space between baffle 44 and cone 42.  The water flows around the tubes 45, mounted in the baffle, to the water space surrounding the cones, and the oil forced downwards to the space 43 from which it rises through the tubes 45 to the oil level.  The cones of the centrifuge may be alternately insulated and connected to a source of direct pulsating or alternating current.  Specification 282,466, [Class 23, Centrifugal machines &c.], is referred to.

Filed: 1933-03-09
Abstract: <PICT:0416082/III/1> <PICT:0416082/III/2> <PICT:0416082/III/3> In apparatus for the manufacture of cement, of the kind in which the raw slurry, before delivery to a rotary kiln 3, is dried and preheated by the waste gases from the kiln, the slurry is applied as a film to the surfaces of carrier bodies, e.g. pieces of chain or netting, attached to a movable support at points which move in a closed path of such form that, during part of their travel, the bodies form a layer resting on the support, and while in this position are subjected to the action of the hot gases.  Fig. 1 shows chains 4 attached to the outer surface of a rotary perforated drum 1 disposed within a chamber 2 which is fitted with a slurry tank 5 into which the chains dip and is traversed by the waste gases on their way from the kiln 3 to the outlet 9.  The dried material is removed from the chains by a rotary beater 6 and is delivered to the kiln by a worm 7 and elevator 8.  A modification is described in which chains are attached to both the inner and outer surfaces of the drum 1.  Fig. 4 shows a further construction in which the drum 1 is replaced by an endless perforated band 15 running over sprockets 16, 17.  The employment of worm 7 and elevator 8 may be rendered unnecessary by arranging the preheater at a level above that of the upper end of the kiln, a shoot being provided to convey the dried slurry directly into the kiln.  The chains 4 may be replaced by pieces of sheet iron 10, Fig. 2, pivotally mounted on bars 11 which form part of the supporting structure.

Title: Apparatus for operation of switches by means of signals
IPC: H02J13/00
Filed: 1917-05-22
Abstract: 244,203. Low, A. M. May 22, 1917. Controlling a p p a r a t u s; coherers.-In a method of selectively closing one of a number of circuits by a corresponding series of impulses, the time interval between successive impulses in a series must exceed a certain value and all the impulses must be received within a given time. The selector is restored by a prolonged current. In the wireless control system described, received impulses of sufficient strength and duration to affect the coherer 1, Figs. 1 and 7, of special construction, are repeated by a relay 2 to the main relay 4 which at each impulse permits the partial rotation of a motor-driven escapement disc 6, which closes for a definite period the circuit of the de-cohering magnet 11<a> so that further impulses during this period are ineffective. The first impulse is repeated by a relay 4 to a magnet 16, which through ratchet mechanism moves the shaft carrying the circuitclosing brush 24 and also releases a motor-driven commutator 17, which during the first part of its movement connects the magnet 16 to the contacts of the main relay 4, and comes to rest in a position in which the release magnet 27 is substituted for the magnet 16. Impulses received during the first part of the movement are thus repeated to the magnet 16, which steps the brush 24 round to the, desired contact 13, this circuit being completed over back contacts 30 of the release magnet 27 when the commutator 17 comes to rest. A prolonged release impulse is repeated to the sluggish release magnet 27 which restores the selector and opens the circuit of brush 24 during the. return movement of the brush.over contacts 13. In a modification, the escapement disc 6 is mounted on a threaded portion of its shaft in such a way that a prolonged impulse permits it to travel along the screw and close a restoring circuit. The motor 7 and other parts are shielded to prevent interference due to sparking. The capacity of the coherer is increased by using filings coated with sulphur or by enclosing the filings in a vessel containing carbon bisulphide. The impulses need not be of uniform duration and they may be of widely different strength, each strength operating a coherer of different type.

Abstract: 891,027. Coating bakers' goods. UNILEVER Ltd. March 7, 1958 [March 12, 1957; April 19, 1957], No. 7392/58. Class 28 (1). [Also in Group XVII] A device for dispensing at least two paste-like materials to form a striped stream comprises a container, which may be formed as a collapsible tube 1 having one or more projections 9 formed in a main passage of an inner tube 2, one or more secondary passages 10 passing through the wall of the nozzle 6 of the tube 2. Each tube is filled at 7 with paste of a different colour, the striping effect being obtained as the paste in the tube 1 is delivered through the passages 10 when the tubes are squeezed. In a modification the bore of the inner tube is divided by projections, Fig. 8 (not shown), which meet at the centre of the bore, in place of the projections 9. Alternatively, Fig. 3, the device may be in the form of a single tube 13 having a tubular insert 15 forming a part of the main passage, paste of one colour filling the space surrounding insert 15 only, the remainder of the tube 13 containing paste of a second colour. Again, Figs. 5-7 (not shown), the tubular insert may have internal projections meeting at the centre, similar to those described above, and such projections may be integral with the tube nozzle rather than on the insert. The tubular insert may define the whole of the main passage. The tube or tubes may be of aluminium. The device may be used in decorating cakes. Reference has been directed by the Comptroller to Specification 813,514.
Patent GB-452930-A (GB)
Title: Improvements in and connected with harrows
IPC: A01B19/10
Filed: 1935-03-09
Abstract: 452,930. Harrows. WILLETT, L. H. M., Bishopstone, and BARTRAM, W. B., St. Vincent's, Cricketfield Road, both in Seaford, Sussex. March 9, 1935, No. 7455. [Class 6 (i)] In order that harrows may be raised and lowered either continuously intermittently or when necessary, they are connected by flexible means to pivoted levers, or to pivoted frames carrying levers, on a wheeled structure adapted to be drawn by a horse or tractor, the levers being tilted to raise and lower the harrows by mechanical devices driven by the wheels. The wheeled structure may consist of a main frame 1 provided with a draw-bar 2 and mounted on the axle 3 of ground wheels 4. A frame 5 pivoted on the axle 3 carries levers 6 connected to a harrow 20 by chains 19, 21 at their forward and rear ends, respectively. The frame 5 and levers 6 are tilted by throwing a pawl 7 into engagement with a ratchet wheel 9 on the wheel 4 by means of a finger-10 mounted on a pin 11 to which is fixed a lever 12 linked to a pivoted and spring-controlled lever 15 movable by means of a cord 17. The front tines of the harrow remain on the ground as the levers are tilted and the pull of the chain 19 thus assists in raising the rear part of the harrow. When the harrow is at its maximum height the pawl 7 is released by striking a stationary cam. An operator on a seat 17a may move the pawl 7 by pressing on a foot-lever 17b. Frictionclutch or band-brake mechanism may be substituted for the ratch-and-pawl mechanism. The frame 5 may be locked when the harrow is in working position ; and a hook may be provided to hold the harrows in position for transport. In a modification the levers are tilted intermittently by cams or crank arms on a shaft driven continuously from the wheel 4. In another modification the main frame is mounted on three wheels and the front of the harrow is pivotally connected to it, the chain 19 being dispensed with. In this construction the levers 6 are pivoted on the axle and are actuated by cams or crank arms engaging the forward ends and mounted on a divided or undivided shaft driven from the wheels. Clutches may be provided. In another modiiication cams engage the levers behind the axle and the rear ends of the levers are connected to the harrow by rigid links. The chains 19, 21 may be connected to brackets adjustably mounted on the levers. The levers may be connected together to form a frame. Chains, bars, or grids, with or without weights, may act as scrapers as the harrow is lifted.
