Title: Improvements in or relating to sewing machines
IPC: D05B69/22
Filed: 1960-04-27
Abstract: 892,077. Sewing machines. NECCHI S.p.A. April 27, 1960 [May 11, 1959], No. 14727/60. Class 112 [Also in Group XXIV] The main shaft of a sewing machine is driven through a single revolution by means comprising a driving member journalled on the main shaft, a spring rigid at one end with the main shaft and coiled around said member to couple the latter frictionally to the main shaft, an abutment adapted to engage the other end of the spring for releasing the frictional coupling, and handoperated means adapted to move said abutment from a position engaging the spring end and to return the abutment to said position before said spring end has completed a single revolution with said member and shaft. The machine is arranged to stop with the needle in its uppermost position, and the machine is thereby enabled to form individual stitches. A pulley 8, journalled on the main shaft 3 and driven by a belt 7, is formed with a surface 9 on which is coiled a spring 10. One end of the latter is anchored by means of an eye 11 to a pin 12 carried by a block 12<SP>1</SP> rigid with the handwheel 13 fast on shaft 3. The other end 14 of the spring is anchored to a radial lug 15 on a ring 16 journalled on the central boss of the handwheel 13. Ring 16 is turned clockwise by spring 10, and the latter thereby grips the surface 9. An abutment 20 may be interposed in the path of movement of lug 15, whereby the latter is moved counterclockwise to engage a rubber pad 19<SP>1</SP> on block 12<SP>1</SP> and spring 10 is unwound to release its grip on surface 9. Abutment 20 is the free end of a lever 21 pivoted at 22 on the machine frame. A spring 24 biases lever 21 to engage an extension 23 on the latter with a cam 25 rotatable by means of a handle (not shown). When extension 23 engages a trough of cam 25, abutment 20 engages lug 15. A lever 30, pivoted at 33 on the machine frame, has pivoted thereto at 29 a lever 28 carrying a lug 31 biased against the edge of lever 30 by a spring 32 on pivot 29. A spring 36 biases lever 30 to engage a nose 37 on lever 30 with a fixed stop 38, when a nose 27 on lever 28 engages a bracket 26 on lever 21. When lever 30 is turned counter-clockwise by means of a handle 35, nose 27 co-operates with bracket 26 to swing lever 21 and thereby disengage abutment 20 from lug 15. Bracket 26 then rides over the upper edge of lever 28, whereby abutment 20 resumes its original position to engage abutment 15 after shaft 3 has turned through one revolution. If cam 25 is turned to engage a crest thereon with extension 23, abutment 20 and bracket 26 are moved permanently out of the paths of movement of lug 15 and nose 27.

Title: Method of forming metal workpieces by electro-chemical metal  disintegration
IPC: B23H5/02
Filed: 1972-03-29
Abstract: 1368841 Electrolytic machining POLYGRAPH LEIPZIG KOMBINAT FœR POLYGRAPHISCHE MASCHINEN UND AUSRœSTUNGEN VEB 29  March 1972 14748/72 Heading C7B A method of electro-chemical machining comprises moving an electrode and workpiece together until contact is made at small protrusions on the metal surfaces, passing an electric current through the electrolyte between the electrode and the workpiece, and moving the electrode and workpiece apart so that when contact is broken, electric sparks ignite hydrogen and oxygen released by the electrolysis. Workpiece 1 rests on sliding table 3 and is fed in direction X against steel strip electrode 2 moving in direction Y. The table 3 is driven by motor 12 via gear-wheel 11 and spindle 10. In order to ensure that only light intermetallic contact is produced the strip 2 is elastically mounted. When workpiece 1 touches the strip 2 contact is made at 9 and the feed motor is switched off. Sparks produced at the subsequent loss of contact at the surfaces ignite the hydrogen and oxygen. Alternatively the feeding rate and operating voltage can be controlled so that the amount of intermetallic contact can be varied. The method is applicable to both cutting and drilling. The electrolyte may be a solution of 5 gms NaCl, 1-3gms NaClO 3 , and 10gms. NaNO 3  per litre of water with a Sg 1À12-1À18 and raised to PH 2-5 by adding an acid such as phosphoric acid.

Title: Improvements in or relating to thermo couples
IPC: H01L35/00
Filed: 1953-06-01
Abstract: 735,925. Thermometers. FOSTER INSTRUMENT CO., Ltd., and OUGHTON, H. G. June 8, 1954 [June 1, 1953], No. 15196/53. Class 97 (3). A thermo-couple which is protected by a sheath, e.g. a metal or ceramic sheath has means for passing a gas, preferably an oxidizing gas such as air, through the sheath to remove and/or counteract any deleterious gases which may enter through the pores of the sheath when hot. As shown, the thermo-couple 1 is enclosed by a metal sheath 5 extending up to a connector head 6. A fan 7 produces forced draught for a furnace, and tube 8 extends into the fan outlet, facing the air stream. Air is thus forced along tube 8 to a stainless steel tube 11 to the vicinity of the hot junction 2, and thence back through sheath 5 until it escapes through holes 12 near connector head 6. The air flow is so slow that it acquires the temperature of the surroundings of sheath 5 in the vicinity of hot junction 2. In a modification, the air flows in the reverse direction.

A typographical line-justification apparatus comprises a binary counter 11 which is initially set to a count representing the required line length. The setting of the six highest stages is also repeated in a second counter 12 by closing switches 8. During operation of character-selection and interword spacing units 9, 10, the width of the characters and the minimum width of the spaces is subtracted in the counter 11, and also in the counter 12 by means of a conductor 6 connecting the "256" stages. In addition, for each space a subtractive entry of 256 units, representing the difference between the minimum and maximum space width, is made to the counter 12 through a conductor 13. When the counter 12 reaches zero, the similar conditions of its six stages are sensed by AND gates 14, and an output signal to a circuit 17 lights a lamp to indicate that justification is possible. When the counter 11 has nearly reached zero, a circuit 18 lights a warning lamp, and at zero a circuit 19 lights a third lamp to indicate that the line can no longer be justified without reducing the inter-word space below the predetermined minimum.

Abstract: 485,814. Briquette presses. JACKSON, L. MELLERSH-. (Krupp Grusonwerk Akt.- Ges., F.) June 7, 1937, No. 15730. [Class 87 (ii)] A briquette press of the kind in which a pressure roller 15, Figs. 3 and 4, rotates within a ring 4 is provided with packings between the roller and the ring, and between those parts and the feeding-device, in order to prevent the material to be agglomerated from escaping. As shown, the ring 4 is provided with a channelled groove 4<1> for co-operating with the roller 15 in order to produce simultaneously two strips A, B of moulded material. The periphery of the roller is made of segments 16, 17 separated by packing 18 and secured by a segmented locking-ring 19 and bolts 20. The material to be pressed is fed into a casing 31 fitting the inner edge of the ring at 33 and the bottom of the moulding grooves at 32, and has a rib 35 extending around the casing and entering into the channel 4<1> below the moulding grooves of the ring 4. The rib 35 is provided with felt packing 38 to close the space between the moulding grooves for the strips A, B, and with further felt packings 36. The slits between the roller 15 and the inner edge of the ring are packed by felt strips 39 acted upon by strips 40 yieldingly pressed by screws 41 carried by arms 42 secured to the casing 31 of the feeding-device. The material is fed from a hopper 21, Fig. 5, to a worm 22 and thence to a worm 23. The worm 23 feeds the material into the casing 31 that is provided with a motor-driven centrifugal wheel 24 having blades 30 for throwing the material into the moulding spaces. The blades are interconnected by a central V-shaped rib 34. The excess of material from the worm 22 passes through an overflow 26 to a return worm 27 that also receives any excess of material from the casing 31 by an overflow 28.
