Title: Bottle coating device
IPC: C03C17/00
Filed: 1957-02-19
Abstract: <PICT:0837322/III/1> Apparatus for coating the outer surface of glass bottles or the like of predetermined size and having an open top comprises two spray guns arranged above and on opposite sides of a conveyer, each gun having an outlet arranged to direct a spray on to the bottles as they are carried in upright position by the conveyer, means for confining the spray from the guns to regions of the bottles below their open tops, and a valve member for each gun normally closing its outlet, control means being operatively associated with each valve member and with the conveyer to open the outlets of the guns simultaneously in response to the movement of a bottle or bottles into a position adjacent to the spraying device.  As shown, conveyer 20 carries bottles 24 past spraying apparatus 26.  This comprises two spray guns 30, each mounted on a rod 60 so as to point downwards at an angle of about 30 degrees to the horizontal on to the shoulders of the bottle. These rods are adjustable vertically by means of rollers 62 and set-screws to accommodate bottles of different sizes.  Each spray gun has a nozzle 48, and is supplied with coating material through conduit 36 and compressed-air for spraying through conduit 46. Nozzle 48 is kept normally closed by a spring-loaded plunger inside the gun.  The other end of this plunger is attached to a piston moving in a cylinder at the rear end of the gun.  The space on one side of the piston is vented to atmosphere, that on the other side is connected through conduit 56 and valve 88 with the compressed-air supply.  A feeler 86 is spring-loaded and is arranged so that when a bottle is in the position shown it is deflected to close the switch 941 in an electrical circuit which energizes solenoid 91 and so opens valve 88 to admit compressed-air to the cylinder at the rear of the gun and so open the nozzle 48 and permit spraying to begin.  When a bottle is not present, arm 86 swings outwards, switch 941 opens and spraying stops.  Shields may be arranged to further protect against entry of material into the bottles.  The supply tank for coating material may be under pressure. Specification 837,323 is referred to.

Title: Improvements in the chlorination of iron sulphide containing materials
IPC: C01B17/06
Filed: 1931-02-25
Abstract: In the recovery of sulphur from material containing iron and other sulphides, e.g. nickel and copper, the material is subjected to a chlorinating agent, such as chlorine, sulphuryl or sulphur chloride, in a reaction chamber, the sulphur is condensed and the chlorides produced are treated with air and steam to produce hydrogen chloride from which chlorine is recovered.  The powdered material is fed into a rotary reaction chamber having a temperature of 450 DEG  C. near the charging end and 300-350 DEG  C. at the discharging end where the chlorinating agent, sulphur chloride, is introduced.  The hot residue containing ferrous, nickel and copper chlorides is treated with air and steam at temperatures of 400-600 DEG  C., preferably 500 DEG  C., to produce hydrogen chlorides and ferric, nickel and copper oxides, the process being carried out in counter-current in a rotary chamber. Means, such as porcelain balls, may be provided to prevent adhesion of the oxides to the chamber.  The issuing gases are dried by sulphuric acid and the hydrogen chloride is treated with air at 530 DEG  C. in a catalytic chamber filled with pumice &c. coated with a chloride or sulphate of copper or nickel to produce chlorine; a chloride may be produced in situ by the action of the hydrogen chloride on the corresponding oxide carried by the pumice, and two or more catalytic chambers may be used. Alternatively, the oxides formed during the steam treatment may be utilized as the catalyst.  The catalytic chamber is maintained at 370-400 DEG  C. though 530 DEG  C. may be employed.  As the reaction is not complete, the gases may be dried and the treatment repeated. Separation of the hydrogen chloride from the chlorine is effected by washing with water from which the hydrogen chloride may be recovered.  Sulphur chloride is regenerated by passing the chlorine so formed, after drying, into molten sulphur maintained above the boiling point of sulphur chloride, e.g. at 150 DEG  C. Specifications 307,190, [Class 1 (iii), Oxides &c., Metallic], 374,069 and 374,070 are referred to.

Abstract: 927,374. Automatic circuit-breakers; arcrupturing in switches; switch contacts. FEDERAL PACIFIC ELECTRIC CO. Feb. 17, 1961 [Feb. 23, 1960], No. 6000/61. Class 38 (5). A moulded case automatic circuit-breaker has two separately-vented arc chambers containing three contacts forming two breaks, electrically and mechanically in series, the arc chambers being sealed from each other during circuit-breaking and in the open condition of the breaker by the intermediate contact. The moving contact 14a is carried by an arm 14 pivoted at 16 and having a pivoted actuator 24 connected by a U-shaped link 22 to a pivoted handle 18, the actuator 24 carrying an ambienttemperature-compensating bi-metal 24a. The arm 14 also carries a bi-metal 26 and a magnetic pole structure 28 to which is pivoted an armature 32 biased anti-clockwise by a spring 34 and spaced from the bi-metal 26, which has an insulating lever 32b engaging a hook 32c of the armature. The contact 14a co-operates with a contact 50b mounted on a copper carrier 50c pivoted clockwise about a shoulder 50d by a spring 52, the carrier also having a contact 50a co-operating with a contact 44a secured to an element 44 slidable in guides 45 against a compression spring 46. Arcing chambers for the contact pairs are formed by the breaker case 10 and cover, by shoulders 54 and ribs 58, these chambers having vents 56, 60 and being normally sealed from one another by the carrier 50c. To close the breaker, the handle 18 is turned anti-clockwise against a spring 36 to rotate, through members 22, 24, the arm 14, the contacts 44a, 50a, 506 being raised by contact 14a during which they engage with a wiping action, Figs. 2, 3 (not shown). The breaker is held closed by the engagement of members 24a, 32 and by members 18, 22 forming an overset toggle, disengagement of members 24a, 32 due to downward flexing of the bi-metal 26 or attraction of the pole 28, allowing springs 36, 46, 52 to open the contacts and restore the mechanism to the position shown in Fig. 1. During opening the arc between contacts 44a, 50a produces pressure which assists the spring 52 to restore the carrier 50c and isolate the arc chambers. Specification 871,931 is referred to.

Title: Device for automatically positioning a floating installation by means of moorings with controlled tension
Inventor: MOULIN PIERRE
IPC: B63B21/50
Filed: 1967-02-09
Abstract: 1,140,796. Automatic position control of floating installations. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. Feb.9, 1967 [Feb. 9, 1966], No. 6289/67. Heading G3R. A floating platform or ship N is automatically maintained in a desired reference position by regulating the respective tensions in mooring ropes 1--6 which are fixed to the water bottom at 7--12 and are controlled by winches 13--18 mounted on the platform N. Each winch (e. g. 13 in Fig. 3) is controlled by a reversible hydraulic motor M having pressure reducing valves (RR 1  ) 13  , (RR 2  ) 13  and safety valves (RV 1  ) 13 , (RV 2  ) 13  which co-operate in pairs according to whether M is acting as a motor or a pump and maintain a substantially constant pressure respectively downstream and upstream of their locations irrespective of variations in flow-rate. The rope tension during winding and unwinding is respectively proportional to the pressure difference between valves (RR 1  ) 13  and (RV 2  ) 13  and between the valves (RV 1  ) 13  and (RR 2 ) 13 . In the described embodiment the valves (RR 1  ) 13  and (RV 1 ) 13  are simultaneously adjusted in response to a control signal produced by deviation in a particular direction from the reference position (e. g. the X axis for the winch 13) so that the winding and unwinding tensions are simultaneously adjusted in the same sense, the control signal actuating the valves through an arrangement comprising gearing and rods operated by a piston movable one way or another according to energization by the signal of one or other of two electrically-controlled valves, Fig. 4 (not shown). The deviation may be arranged to control one winch and/or the other with which it co-operates, e.g. winch 13 and/or winch 16 for a displacement in the X direction, so that appropriate variation in the rope tension(s) provides a limiting and then a restoring force. Response of the system may be immediate or after a predetermined displacement, which may be detected by known devices, e. g. a tiltmeter, inclinometer, gyroscopic compass, ranging or beaconing devices using radio waves, or means for detecting the rotation of the winch. Typical arrangements are described for using deviation signals derived from X, Y axis and angular displacements to control the winch valves, Figs. 5, 6 and 7 (not shown). The signal may be represented by the number of a series of constant amplitude signals or by the value of a single signal, may be intermittently applied, and may include a differential component representative of the speed of displacement. Delays may be introduced into the regulation of the rope tension to achieve desired correcting or restoring effects. Safety is ensured by providing each winch with an electromagnetic brake 61 responsive to the pressure in the pipe 26.

Abstract: 1424371 Fluid-pressure servomotor systems G TEATINI 8 Feb 1973 [29 Feb 1972] 6323/73 Heading G3P A flow regulating valve comprises a closure member 9, Fig. 1, slidably arranged within a chamber 4 connected with upstream flow via throttled passage 5 and with downstream flow via throttled passage 16. Adjustment of lever 25 compresses spring 30 so that adjustable spring 28 can pivot lever 20 about pin 21 in a direction causing needle 18 to reduce the throttling of passage 16. The consequent fall in pressure in chamber 4 causes the closure member 9 to move away from its seat 10 to an equilibrium position and establish throughflow. Variations in the flow-rate are sensed by a disc 24 causing movement of the throttle 18 and consequent compensating movement of the closure member 9. The latter may also be moved in accordance with other variables such as changes in upstream and downstream pressure or any pressure differential. In Fig. 3 (not shown), the upper end of the lever 20 is acted on, in addition to the spring 28, by means (31)  responsive to downstream pressure. In Fig. 4 (not shown), the lever 20 is replaced by a pivoted lever  and leaf-spring device (122, 125), the closure member is arranged at the upstream end of the  valve, and the needle throttle is replaced by a  piston-type slide valve (115).

Abstract: 689,427. Smallarms. PROLA, G., and PROLA, C. March 16, 1951 [March 16, 1950; Feb. 22, 1951], No. 6409/51. Class 119 A self-loading firearm with fixed barrel comprises a breech-block 6 and a link 7 connected therewith, the link being adapted to descend during the rearward motion of the breech-block under the actior of an inertia mass 8, which is adapted tc move forward slightly on firing and before the shot has left the barrel and then tc recoil to engage the link and carrying the breech-block into an open position. Fig 1, shows the position of the parts at the moment of discharge. the hammer 20 which has just been released from engagement with a sear 23 by the pull of either one of two triggers 24, 25, being shown in the act of striking the firing pin 55 in the breech-block 6. Upon discharge the mass 8 moves forwardly through a small distance when the gun recoils to compress a spring 65; the energy thus stored is used immediately afterwards to drive the mass rearwardly into the butt 4 against the action of a return spring 18. Fig. 7. As the mass recoils a shoulder 60 in a recess thereof engages with a nose on the lever 7, such engagement serving first to move the lever downwardly from locking engagement with the front faces of fillets 13 in the breech casing and then to pull the lever and thus the breech-block to the rear. The breech-block is guided at 11 in the casing and its recoil serves to re-cock the hammer 20, and also, by extractor 56, to bring the spent case against a fixed stop in the casing cover 3. The stop ejects the case through a side aperture in the cover. this aperture being closed at the time of firing bv a plate 58 pivoted to the breechblock. The mass 8 is temporarily held in the retracted position by the engagement of a catch 39 thereon with the rear end of a cartridge elevator 32. In the meantime a forward extension 27 of the pulled trigger has moved a lug 28 or 29 at the front of a pivotally mounted magazine (not shown). and a fresh cartridge is fed bv the magazine spring on to the elevator, the cartridge moving aside an elevator-retaining detent 36, Fig. 3, during this movement. The elevator is now free to rise under the action of a spring to bring the cartridge into line with the breech. and at the same time to move clear of the catch 39 on the mass 8. The spring 18 then moves the parts 8, 7, 6 to the loading position, a second nose on the mass 8 moving the lever 7 to the locking position during this action. A lever 41, Fig. 7, fulcrummed at 42 in the butt is suitably linked to the mass 8 to effect cocking by hand.
