Patent GB-1233455-A (GB)
IPC: F02D41/12
Filed: 1968-07-11
Abstract: 1,233,455. Electric control systems. ROBERT BOSCH G.m.b.H. July 11, 1968 [July 12, 1967], No.33016/68. Heading G1N. [Also in Division F1] In a fuel injection system for an internalcombustion engine comprising a solenoid operated fuel injection valve 3, the open period of which is controlled by the duration of the unstable state of a monostable multi-vibrator C in accordance with the pressure in the intake manifold, opening of the injection valve when the air intake butterfly valve (9) is in its idling position and the engine is running at a speed in excess of its idling speed is prevented by a switching circuit A which interrupts the transmission of triggering pulses to the monostable multi-vibrator C. In operation, pulses generate by a cam operated switch 10 cause momentary blocking of a normally conductive transistor thereby making a normally blocked transistor 50 conductive to trigger the monostable multi-vibrator C. When the butterfly valve (9) is not in the idling position, a switch 38 is open allowing a timing capacitor 31 to discharge rapidly through a transistor 30, diode 36 and resistor 37 so that transistor 40 reverts to its normal conductive state ready for the next pulse from the switch 10. However, when the butterfly valve is in its idling position, the switch 38 is closed thereby blocking diode 36 and retarding the discharge of capacitor 31. If the engine speed is great enough for the next pulse from switch 10 to occur before capacitor 31 has discharged, this pulse is not transmitted to the monostable multivibrator C because transistor 40 is still blocked. The engine speed at which cut-off becomes effective is made temperature dependent by an N. T. C. resistor 20 in thermal contact with the engine. When the engine is cold, diode 32 is conductive thereby increasing the discharge rate of capacitor 31. When the engine is hot, diode 32 is blocked. Hysteresis is introduced by a normally conducting transistor 80 which becomes blocked momentarily each time the multi-vibrator C is triggered thereby making diode 34 momentarily conductive to increase the discharge rate of capacitor 31. When the cut-off is effective, diode 34 is continuously blocked whereby triggering of the monostable multi-vibrator C is only resumed after the engine speed has dropped to a value sufficiently below that at which the cut-off became effective. The duration of the open period of the injection valve is controlled by arranging the position of the core 75 of a transformer in the timing circuit of the multi-vibrator C to be governed by the pressure in the inlet manifold.

Filed: 1965-08-03
Abstract: 1,121,992. Collars. A. LENZ. 3 Aug., 1965, No. 33087/65. Heading A3V. A collar comprises an interlining covered on both sides by a facing consisting of one or more pieces folded about the interlining at the ends of the collar and joined transversely of the collar by a seam or seams disposed on the underside of the collar so as to be invisible in wear, the facing being stitched to the interlining along the bottom edge of the collar, i.e. the edge remote from the neck in wear, the stitching being the only connection between the interlining and at least the cape portion of the facing. As shown, Fig. 4, a cape portion facing in two parts seamed on the underside at 3, 4, is placed with its bottom edge 6, overlying the edge portion 7 of an interlining 8 and stitched thereto at (9), Fig. 5 (not shown). To facilitate the sewing of seam 9 the two layers of the facing may first be sewn together at 5. The facing is turned round the interlining 8 and is ready to be secured to a neckband. A collar in which the cape portion and the neckband formed in one has button and buttonhole flaps joined to the facing at U-shaped cutouts therein, the angle of the U being such that, in the finished collar, the seams joining the flaps to the facing are hidden by the cape portion of the collar. In a further one-piece embodiment Fig. 17, the top and underside facing pieces 1 and 2 respectively are assembled as shown in Fig. 14 by seams 28. A multi-layer interlining, Fig. 16 (not shown) comprises a main piece (31) of approximately the same shape and extent as the facing, to which is secured, preferably by adhesive, a cape piece (32) which stops about 8 mm. short of the bottom edge of the main piece, a reinforcing patch (38) being stuck at each end of the layer (31). Extensions (33) of the piece (32) have bones (35) stuck or stitched to them and extensions (36) of the piece (31) overlie the collar fold line to soften it at the collar ends. A line of adhesive 37 is applied to the piece (32) for securing a fold line reinforcing strip. The facing is placed on the composite interlining with the top fabric 1 adjacent the piece (31) and the bottom edges level and is stitched thereto by a seam 40 which only passes through the piece (32), bisecting the 8 mm. portion referred to. The facing 1, 2 is turned over the interlining as indicated by the arrow in Fig. 17 whilst the pieces (31) and (32) are stitched together at (41) (Fig. 18, not shown) between the seam 40 and the bottom edge of the piece (31). The extensions (33) are then turned in on to the piece (31) and the facing 1, 2 turned over the interlining.

Title: The recovery of sulphur
IPC: C01B17/06
Filed: 1931-12-01
Abstract: In the production of sulphur from metallic sulphides, such as iron pyrites, spent oxide, &c., the material is treated with superheated steam in a reaction chamber at a temperature of 440-1000 DEG  C. whereby sulphur. metallic oxides, hydrogen and sulphuretted hydrogen are formed, the hydrogen sulphide being largely decomposed to hydrogen and sulphur.  The reaction is maintained by the temperature or the amount of steam supplied and the conditions are such that all the reaction products resulting in the formation of sulphur leave the chamber in the gaseous or vaporous form.  Any sulphur dioxide produced at higher temperatures reacts with sulphuretted hydrogen to produce sulphur. In a continuous method of treating iron pyrites, the pyrites, ground to pass a three eighths inch screen, is fed into the top of the chamber and treated with superheated steam at 900 DEG  C. introduced from below.  Steam and sulphur are removed from the gases by condensation and the hydrogen sulphide is absorbed by water in a scrubber, the hydrogen being either collected or used for steam generation.  Hydrogen sulphide is recovered from the scrubbing liquor by reduced pressure and returned to the reaction chamber. Alternatively, the sulphur may be removed electrostatically, the steam and gases being reheated and returned to the process.  In a second modification, the pyrites is finely ground and fed in with the steam at the base of the reaction chamber, the iron oxide carried over being deposited in a settling chamber or in an electro static precipitator maintained at above the boiling point of sulphur. Specification 18007/14, [Class 90, Non-metallic elements &c.], is referred to.

Title: Automatic machine for punching and shaping sealing caps or covers and feeding them to containers
IPC: B67B3/02
Filed: 1946-11-20
Abstract: 630,261. Applying closures to bottles. CHELLE, P. L. Nov. 20, 1946, No. 34412. Convention date, Jan. 17, 1946. [Class 125(ii)] In a machine for punching and shaping sealing caps from continuous metal strip, and delivering them to bottles or like containers fed by a conveyer associated with the machine as the containers pass in front of the machine, the machine being of the kind in which the passing of a container on the conveyer controls; through a linkage actuating a clutch on the machine drive shaft, the movements of the metal strip and a punching die, the caps after being punched and shaped by the die drop onto projections on a horizontal rotary plate which brings them into the path of movement of a rotary ejector. As shown, Fig. 1, a slide 59 carrying the punching die 58 is actuated by a rod 62 at the lower end of which is a frame member 63 reciprocated by a cam 15 and a return cam 66. Cams 15 and 66 are both fixed to a sleeve 7 which is freely rotatable on driving shaft 5, and is driven therefrom via a sleeve 8 having a ratchet flange 10, and a pawl 12 carried by cam 15. Flanges 6 connect shaft 5 with the driving shafts of a milk filling machine on one side and a sealing machine on the other. Absence of a bottle 4 from conveyer 2 allows lever 25, Fig. 2, to swing over, movement of a ramp surface 24 permitting a lever 20, keyed to shaft 19, to rise, thereby depressing a lever 18, Fig. 1, also keyed to shaft 19, which forces pawl 12 out of engagement with ratchet flange 10. The drive to sleeve 7 is thus interrupted, arresting the movement of die 58 and also of the metal strip feed rollers 32, 33 which are intermittently driven from sleeve 7 via a Maltese cross member 45. Aluminium strip 40 is drawn from a reel 29, and after punching, the scrap strip is wound on a reel 34 driven from roller 33 via a friction transmission disc. Before passing under die 58, the strip is given an annular coating of neutral oil on both faces, where the cap is to be cut, by two felt rings which are supplied with oil from a pump 72 and are brought into contact with the strip by movement of an arm 81 carried by slide 59. After a cap has been punched, shaped and released by die 58, it falls onto one projecting arm of a rotary member 88 driven from shaft 5 via shaft 89. Member 88 propels the formed cap through a passage which causes a projecting ear on the cap to be correctly angularly positioned after which it is passed by a rotary ejector 94 through a further passage 97 where it is sterilized by the flame from an alcohol burner, the flame being lowered to a pilot flame in the absence of a bottle by a linkage 106 operated by lever 20. The cap 100 is then delivered down a chute 98 to a distributer 99, where it is resiliently retained by two spring arms 114 until it is removed by a passing bottle 4, rubber scraping members 111, 112 serving to engage the cap correctly with the bottle mouth.

Filed: 1921-12-21
Abstract: 173,503. Jacquelin, A. Dec. 28, 1920, [Convention date]. Reciprocating or oscillating sieves. - Oscillating sieves carried by a pivoted triangular frame and reciprocated by a crank or eccentric are mounted so that perpendiculars from the pivotal point fall outside the perforated portions of the sieves towards the front ends to which the material is travelling, the vertical component of the radial movement thus decreasing as these ends are reached. Damping arrangements, comprising sets of opposed spiral springs, are provided to overcome inertia effects. A series of sieves 4 - - 9 are carried in a casing 1 pivoted on a shaft 2 by angularly arranged legs 3 so situated that perpendiculars from the shaft 2 to the sieves fall outside the fronts of the sieves. The material to be sieved is fed over a plate 20 which may be partly replaced by a grid 21 for the removal of dust. Plates 24 - - 29 are provided to collect the various grades of material from the sieves, the product from the lowest sieve passing, if need be, through a grid 22 into a shoot 30 to which the dust separated by the grid 20 may be communicated by a passage 31. To prevent too rapid a movement along the sieves, angle-pieces 34 - - 39 are mounted thereon. Movement is imparted to the sieve by a crank or eccentric through a rod 48 which may be rotated by hand, mechanically, or by a motor 43. The damping-device comprises a series of springs 44, 45 placed on either side of a fixed support 46 and surrounding the rod 48.
