Filed: 1967-08-21
Abstract: 1,150,119. Open-end spinning. SCHUBERT & SALZER MASCHINENFABRIK A.G. 21 Aug., 1967 [24 Aug., 1966], No. 38335/67. Heading D1D. In an open end spinning m/c the thread outlet tube is axially displaceable e.g. by an arm 67 to adjust the position of its mouth in the spinning chamber for different spinning conditions. The upper end of the tube may be formed with grooves or ribs or be sandblasted or be of a high friction material such as rubber. A number of axially displaceable tubes 610, 600, 620 may be provided one within the other so that by adjustment the forming yarn can be passed in contact with any of their ends which may be similar or different in surface finish and shape. As shown the separate tubes may be adjusted so that the yarn contacts a plurality of tube ends and passes along a curved path. The tubes may be non-rotatory or be rotated with the chamber 2. In Figs. 4 and 5, not shown, the spinning chambers are formed with lips against which the yarn rubs on its passage from the yarn forming surface to the outlet tube.

Title: Method of melting down solid metallic charge materials in metallurgical furnaces, for example in basic-oxygen converters
IPC: C21C5/56
Filed: 1965-09-08
Abstract: Solid metallic charge material such as scrap, pig or sponge iron is melted down in a metallurgical furnace e.g. a basic-oxygen converter using a fuel-oxygen burner by first pre-heating the charge material to white heat, i.e. above 1000 DEG C. but below its M.P. e.g. to 1200 DEG C., with a broad short flame which impinges on the whole charge surface, and then melting down with a narrow long flame which impinges on the central charge portion only, the burner distances from the charge surface being such during each period, e.g. 250 mm. in the pre-heating period and a constant 400 mm. in the melting down period, that the hottest zone of the flame touches the charge surface. A broad short flame may again be produced after the melting down period to melt remaining outermost solid portions of the charge. The final bath temperature may be 1610 DEG C.  The above process may be carried out in the converter while stationary and upright; after melting the converter may be rotated in the inclined position.

Title: Improvements in or relating to Change Speed Actuating Mechanisms.
IPC: F16H63/14
Filed: 1967-08-21
Abstract: 1,185,396. Change-speed control. HONDA GIJUTSU KENKYUSHO K.K. 21 Aug., 1967 [30 Aug., 1966], No. 38498/67. Heading F2D. In a ratchet stepwise shift change-speed control in which movement of the gear pedal 6 causes step-by-step rotation of a selector drum 1 through claws 9 and 10 on a lever 8 engaging pins 12, 13 on the drum, the neutral position is provided between the second and first speed positions, and neutral is always found on attempting a 2-1 downshift, two steps of the pedal 6, second-neutral and neutral-first, being required to effect such a downshift. As shown, the pin 13 is provided with a head 13A on which the arm 8 slides. Positive stops 24, 26 provided on the drum 1 and arm 8 respectively, abut to prevent further movement of arm 8, when moving from second to first, to find neutral, but, on releasing pedal 6 which returns to its inactive position under the action of spring 4, claw 9 rides on a cam surface 25 provided on stop 24 which cams the lever 8 off the head 13A of pin 13 on to the body thereof, spring 14 maintaining the lever against the side of the head. On again stepping the pedal 6, the stops are thus clear of each other, and first speed position is attained. Change speed arm 8 is then withdrawn by return spring 14, pin 12 pushing the arm 8 via the normally inoperative surface of claw 9 away from the pin neck towards and into contact with the pin head 13A. A spring-loaded roller detent 23 abuts concave surfaces 17-21, representing first-fourth speed positions and neutral respectively, in a cam plate 15 on drum 1, to retain the drum in its selected speed position.

Title: Bimetallic timing mechanism for automatic bread toaster
IPC: A47J37/08
Filed: 1971-08-17
Abstract: 1332057 Electrically released switches; timing devices ROWENTA-WERKE GmbH 17 Aug 1971 [28 June 1971] 38510/71 Heading H1N A timing mechanism for an automatic toaster comprises a sliding member 46 coupled to the bread carriage of the toaster and operating main on/off contacts 32; a catch 40 for retaining the member 46 in its depressed position; and a pivotally mounted bi-metal blade 13 which is heated electrically during the early part of the toasting period, then acts on contacts 23 to stop the heating and finally cools towards its initial position in which it releases the member 46 to switch off the toaster and raise the bread carriage. When the sliding member 46 is depressed to start a toasting period an abutment 27 engages an arm 41 of the catch 40 depressing it below a slide 33 which moves under the tension of a spring 34 to retain the catch; when the member 46 is released it moves up under a spring 47 until the catch 40 engages a projection 42. The distance that the slide 33 is moved by spring 34 is determined by a cam 36 which is set by a knob 37 for adjusting the toasting period. As the bi-metal 13 is heated by its heater 14 it curls towards a slot 38 in slide 33 into which it eventually pivots under the action of a spring 20; an extension 21 on the bi-metal closes contacts 23 to short the heater 14. The bi-metal then cools pulling back to slide 33 as it uncurls eventually releasing the arm 41 of catch 40 to terminate the toasting period. The shaft 15 and the bi-metal 13 are threaded so that rotation of the shaft by a screwdriver slot 17 (Fig. 1, not shown) causes displacement of the bi-metal to set its operating range; the bi-metal is U-shaped or has a boss (not shown) to give it stability on the shaft 15. A further adjustment may be provided by a screw between the arm 41 and the frame 28.

Abstract: 1,066,187. Stretching polycarbonate filaments and films. FARBENFABRIKEN BAYER A.G. Sept. 22, 1964 [Sept. 25, 1963], No. 38595/64. Heading B5B. Filaments and films of high molecular weight crystallizable polycarbonates which have been stretched are further stretched at a temperature within 5 C. of that at which the tangent of the dielectric loss angle of the filament or film has its first subsidiary maximum, measured at a frequency of 1 kilocycle per second. Both the first and second stretching steps are effected in the longitudinal direction when the polycarbonates are in the form of films. The initial stretching may be effected at a stretch ratio of 4: 1 to 5: 1 and the elongation effected during the further stretching may be 20 to 50%. The polycarbonates may be prepared by polymerizing di - monohydroxy - diarylalkanes, -sulphones, -sulphoxides, -sulphides, or -ethers or mixtures of these dihydroxy compounds with each other. In an example, a polycarbonate prepared by the polymerization of 2: 2-(4: 4<SP>1</SP>-dioxy-diphenyl)-propane having an average molecular weight of 32,000 is melt spun to form filaments which are stretched at a stretch ratio of 3À5: 1 at the optimum temperature of 175 C. The filaments are then stretched at a temperature within the range 100 and 110 C. to a degree such that they are elongated 25%. On the basis of measurements of the tangent of the dielectric loss angle at 1 kilocycle per second the maximum value of this property is found to occur at 105 C.

Title: Control valve assembly
IPC: F23K5/04
Filed: 1973-08-16
Abstract: 1432185 Valves DANFOSS AS 16 Aug 1973 [22 Aug 1972] 38732/73 Heading F2V [Also in Division F4] An oil burner control valve assembly comprises a cut-off valve 7, for closing a pressure line 4 from a pump 1 to a nozzle 6 when the pressure in line 4 falls below a predetermined level, a pressure-regulating valve 10 in a return line 9, 20 acting to maintain a substantially constant pressure in line 4, a control device 11 in series with valve 10, and a normally closed bypass valve 16 in parallel with valve 10 and device 11, device 11 acting to open valve 16 whereby valve 7 closes rapidly when the flow rate falls below a predetermined value. A check valve 48 may be located in series with by-pass valve 16. Valves 7, 10, 16, 48 and device 11 are defined by components located in a bore 18 of the pump casing 19. When the pump starts oil flows to line 4 and via a peripheral recess 27 in a slide 23 and a chamber 21 to act initially on part only of an end wall 25 of slide 23 whereby the slide moves against a spring 24 to open valve 7, comprising face 25 and seal 26, the initial opening exposing the whole face 25 to the oil pressure to execute full opening rapidly. Movement of slide 23 moves recess 27 into communication with return opening 21, recess 28 and opening 22 defining the pressure regulator 10 whereby the oil pressure urges a piston 38, having a spindle 41, fluid-tightly sliding in a stop ring 33 fixed in slide 23, against a spring 40 whereby oil flows between piston 38 and an inner wall 39 of slide 23 to a chamber 30 and thence to return line 20, piston 38 and wall 39 defining a flow restrictor 12 of device 11. When the pump is de-energized pressure in line 4 drops, spring 24 partly closes valve 7, 25, 26 and spring 40 urges piston 38 leftwards whereby spindle 41 acts through oil in chamber 42 and part 37 of a slide 34 to urge slide 34 leftwards relative to slide 23 against spring 35 whereby a transverse bore 31 in slide 23 is uncovered and oil flows from line 4 through bore 31, a gap between slide 34 and ring 33, a transverse bore 45 in spindle 41 and thence via bore 46 of spindle 41 and chamber 30 to return line 20 whereby pressure in line 4 is rapidly lowered and spring 24 closes valve 7, 25, 26. Bore 31 and wall 36 of slide 34 define the by-pass valve 16 and a recess 44 in spindle 41 and inner peripheral surface 47a slide 34 define check valve 48. The oil in chamber 42 flows thereto when piston 38 is in its rightwards position from chamber 30 via bores 45, 46 of spindle 41 and via a clearance 43 between spindle 41 and part 37 of slide 34. When valve 7 has closed and the pump has stopped, spring 35 gradually returns slide 34 to the start position, Fig. 2, as the oil in chamber 42 is discharged to return line 20 via clearance 43, bores 45, 46 and chamber 30.

Title: Improvements in or relating to internal combustion engines
IPC: F02D9/18
Filed: 1961-10-30
Abstract: 950,670. Spray carburetters; silencers. FICHTEL & SACHS A.G. Oct. 30, 1961 [Nov. 19, 1960], No. 38799/61. Heading F1B. [Also in Division G3] In a hollow annular, throttle regulating member 2 for an I.C. engine, the air flow is controlled by varying its internal diameter through variation in the pneumatic pressure in the space 3, which is bounded on all sides or only in the vicinity of the variable internal diameter by an elastic wall, the space being connected by a pressure feedback pipe with a region of vacuum or over-pressure existing within the engine, regulation being effected by varying the feedback pressure. When valve 17 is opened or closed the vacuum in crank-case 14 and intermediate pipe 12 produces a pressure reduction in space 3 through pipes 13, 4, which distorts the elastic wall 2 to decrease or increase the flow crosssection 11. In a modification, the elastic wall of hollow space 3 is bounded outwardly by the bore in the carburetter. In another embodiment the space 3, Fig. 3, communicates with crank-case 14 through a non-return valve 21. A vacuum is produced in space 24 by the vacuum existing in the duct 37 of a coolant air blower 38 by which the diaphragm 26 is lifted to admit air through groove 25 to pipe 27 in order to prevent rise of engine speed above a predetermined value. For cold-start conditions a valve 22 in fuel pipe 19 admits fuel into pipe 4. In a further embodiment, the overpressure produced in an engine muffler acts on the annular space and for starting a piston acting in a cylinder against a spring compresses the air in the annular space to reduce the throttle cross-section. The fuel pipe 7 is controlled by a needle 36.

Title: Improvements in or relating to constant pressure regulators, especially for gases
IPC: G05D16/06
Filed: 1956-12-20
Abstract: 856,201. Fluid-pressure servomotor control systems; valves. VENNER, H. A. L. (Massindustrie Werdau VEB.). Dec. 20, 1956, No. 38907/56. Class 135. A pressure regulator, more particularly for maintaining a constant pressure of gas supplied to pneumatic gauging apparatus, consists of a fixed closure member 11 coacting with a movable member 5 supported by bellows 1, 2, 3 and arranged to be set into oscillation to effect pressure control. The member 5 is biased downwardly by a loading spring 4 or by a weight or a combination of spring and weight so that gas entering the regulator through a connection 18 and passing through a passage 21, the interior of the bellows 3 and an annular throttling passage 23 passes to an outlet chamber 24, where it reacts on the member 5 causing it to move upwardly. The outlet pressure also passes through the hollow centre of the fixed member 11 and a passage 30 to the annular space 26 between the bellows 2, 3 thereby urging the member 5 downwardly. Oscillations of the member 5, which are generated by the friction of the fluid flowing through the member 5 and by the fact that as the opening between the members 5, 11 increases the area of the throttling passage 23 decreases, are stated to vary both in frequency and amplitude in such a manner as to maintain a substantially constant pressure of gas flowing from the outlet of the regulator. The gas flows from the chamber 24 to the outlet by way of passages 25 and a helical passage 16 formed between inner and outer body members 15, 17, the walls of the helical passage being of a material having good heat conductivity so that the gas attains room temperature before leaving the outlet. The fixed member 11 is mounted for adjustment of alignment by means of a domed end 10 seating against a conical recess 12 in a cap 27 at the upper end of the body and held in its adjusted position by a nut 14 screwing on to the connection 18. To provide a degree of damping of the oscillations should the regulator be used to control large rates of flow liquid may be introduced into the chamber 26 or into the space 29 between the bellows and the body member 15. A safety valve 35 loaded by a spring 36 against which it is opened by pressure in a bellows 34 vents the chamber 26 to atmosphere in the event of excess pressure in the helical outlet passage 16.

Title: Improvements in and relating to automatic traverse mechanism
Inventor: LOWE GERALD WILLIAM
IPC: F16H47/02
Filed: 1966-09-01
Abstract: 1,138,743. Automatic reversing drives; tensioning chains. BERRIDGE ENG. Ltd. 10 Aug., 1967 [1 Sept., 1966], No. 38967/66. Headings F2D and F2Q. [Also in Division B2] An automatic traverse mechanism moves a carriage 13 carrying one or more spray guns (not shown) to and fro along a guide 12. The carriage is secured to one flight of a drive chain 16 passing round sprockets 17, 19 at opposite ends of the guide 12, sprocket 17 being secured to an output shaft 18 of a drive unit 11 comprising an electrically driven hydrostatic transmission including a variable displacement reversible hydraulic motor. The motor displacement is controlled by a lever 25 secured to a control shaft 24 and spring-urged to a neutral position for zero motor displacement. When the carriage trips one or other of two limit valves 14, 15 adjustably secured to the guide 12, a double-acting pneumatic ram 27 is actuated to move the lever 25 to reverse the hydraulic motor and hence the carriage. To centre the lever 25 a pin 30 thereon is acted upon by arms 31a, 31b pivoted at 24 and urged together on to a stop 33 by a spring 32. Alternatively, (Fig. 9, not shown), arms (31a, 31b) are parts of respective bell-cranks, the other arms 31c, 31d of which are acted on by springs (60a, 60b). Adjustable stops 34a, 34b limit the movement of lever 25 in opposite directions from its neutral position, to control the carriage speeds, which may be different, in the two directions of movement. The drive chain is tensioned by bolts 23 which position bearing blocks 22 for the sprocket 19 relative to a housing 20 on the guide 12. The guide 12 is mounted on drive unit 11 so as to be adjustable to any desired inclination. The pneumatic control circuit (Fig. 3).-With manual valves 35, 36 open, compressed air is admitted alternately to the two ends of ram 27 under the control of a reversing valve 37 actuated by air from the normally closed limit valves 14, 15 when the carriage reaches one or other of them. With valve 35 closed, opening of a manual valve 38 causes a single cycle of carriage movement to be completed, the opening of valve 15 admitting air to close the valve 38. The traverse mechanism is used in paintspraying apparatus (see Division B2).
