Title: Improvements in or relating to the manufacture of glassware
IPC: C03B9/30
Filed: 1940-03-13
Abstract: 537,795. Glass manufacture. BRITISH HARTFORDFAIRMONT SYNDICATE, Ltd. March 13, 1940, No. 4726. Convention date, March 17, 1939. [Class 56] Apparatus for blowing and internally cooling hollow glass articles comprises a blowhead with a tube for delivering pressure fluid to the interior of a parison in a mould and with an outlet to the atmosphere, and cam operated valves for controlling the inflow and exhaust of pressure fluid. The pressure fluid may be steam, vapour, air, or other gas as described in. Specification 537,796, and means are provided scavenging residual fluid from the interior of the article after the blowing and main cooling have been completed. U.S.A. Specification 2,123,145 also is referred to. The blowhead may be supported on a vertical reciprocating rod 10, Fig. 1, which may be the piston rod of a pneumatic cylinder 11 as described in Specification 257,637, [Class 56]. A bracket 15, clamped to the rod, has at its outer end a vertical bore in which is mounted the hollow stem of a chuck or holder 18 for a blowhead 19. A tube 25, for delivering air or gaseous fluid under pressure to a parison 27 in a mould 28, has its upper end secured to a plug in the holder 18, the plug dividing the holder into upper end lower chambers. The upper chamber is connected to a valve 37, Fig. 5, which controls the admission of pressure fluid to the tube 25, and the lower chamber is connected to a valve 42 which controls the escape of pressure fluid from the glass article in the mould to the atmosphere through an exhaust pipe. The end of this pipe is covered with a deflector to protect the operator from injury when steam or hot pressure fluid is used. The escape of pressure fluid cools the interior of the glass article. The valves 37, 42 are opened at appropriate times by cams 46, 47, respectively, on a shaft 48 which may be rotated continuously but preferably is turned step-by-step by a ratchet pawl 57, Fig. 1, which is oscillated by a rack 55 operated by a pneumatic cylinder 68. After the glass articles have been blown, and while they are being carried by a conveyer 99, Fig. 9, to a leer or to other machinery, they pass under a hood 100 having a bottom plate 101 with numerous small perforations. Dry air under pressure blown through these perforations in small jets, enters the glass articles and forces out any steam or residual moisture that remains in the articles.

Patent GB-979378-A (GB)
Title: Manufacture of dense sodium carbonate
IPC: C01D7/35
Filed: 1963-02-06
Abstract: Dense sodium carbonate is prepared by reacting caustic soda solution with sufficient sodium bicarbonate, with or without CO2, in the presence of anhydrous Na2CO3 to fix all water as Na2CO3.H2O and calcining the monohydrate. Caustic soda solutions, containing more than 40% NaOH, may be those from the electrolysis of sodium chloride in mercury-cathode cells, at 70 DEG  C.  The crude product of the carbonation of ammoniacal brine in the ammonia-soda process may be the moist sodium bicarbonate, and the light Na2CO3 product of such process, at 180 DEG  C. may also be the anhydrous Na2CO3. The reaction may be at 100 DEG  C. in a stirred vessel, a paddle or screw mixer, or a rotating drum.  The reactants may be added simultaneously or successively in any order, e.g. bicarbonate, carbonate, solution, or solution, bicarbonate, carbonate, or half carbonate, bicarbonate, half carbonate, solution.  Alternatively, a saturated solution of Na2CO3 may be added to the three reactants, giving a more fluid magma, e.g. 200-400 g./1000 g.  The saturated Na2CO3 solution after removal of the Na2CO3.H2O may be used again.  Particle size distribution of the final product is tabulated.

Title: Coal breaker
IPC: B02C4/28
Filed: 1960-02-11
Abstract: 923,206. Coal breakers. A. OELLRICH, [trading as MASCHINENFABRIK UND EISENGIESSEREI A. BEIEN.]. Feb. 11, 1960 [Feb. 12, 1959 (2)], No. 4898/60. Class 59. A coal breaker the drive for the breaker elements of which is provided with a safety coupling which has at least one safety element adapted to be loaded to breakage and in which the passage cross-section is adjustable or variable by means of a lifting device is characterized in that a reversal safety device connected between the safety coupling and the lifting device is connected to a propellant line and constructed as a control system which in the event of breakage of the safety coupling automatically reverses and in so doing brings the lifting device into the open position. The reversal device preferably has associated therewith a warning device which may be an acoustic signal. The breaker shown in Fig. 1 comprises a breaker roller 6 mounted in a member 3 which is rockable about an axis 2 relative to a base frame 1. The roller 6 is driven by a motor 4 through a transmission 5. Cylinders 7 are pivotally connected between the frame 1 and the free end of the member 3. In normal operation, the lower chambers of the cylinders are operated by means of compressed air, or pressure liquid, supplied from a line 9 through a four-way cock 10 and a control slide 12 while the upper chambers of the cylinders are vented through the slide 12 to the cock 10. A branch line 17, 17<SP>1</SP> leading to an end chamber 19 of the slide 12 contains an operating member 18 in the form of a shut-off cock disposed on the housing of the transmission 5. A whistle 20 is connected to the line 17<SP>1</SP>. A crown wheel 23, Fig. 2, driven by the motor 4 drives the shaft 22 of the transmission 5 through a coupling bush 24, a breaking element 25 and a claw coupling 29. The breaking element has an annular recess 30 which predetermines the breaking point. When an undesirably high resistance occurs in the region of the breaker roller, the breaking element divides into two parts 25a, 25b. The part 25a remains coupled to the shaft 22 while the part 25b continues to be rotated by the crown wheel 23. An eccentric sleeve 31 secured to the shaft 22 then pushes outwardly a pin 32 slidably mounted in the bush 24 so as to move angularly a spring- influenced rocking lever 34 mounted on the member 18 thereby connecting the lines 17, 17<SP>1</SP>. This has the effect of venting the lower cylinder chambers and of supplying compressed air to the upper cylinder chambers to lift the member 3 and thereby increase the passage cross-section of the breaker. At the same time, the whistle 20 sounds. The motor 4 is then stopped and a main shut-off valve 21 closed. After replacement of the element 25, the pin 32 is pushed inwardly to break the connection of the lines 17, 17<SP>1</SP>. The motor 4 is then started and the valve 21 opened whereupon the breaker resumes normal operation.

Title: A device for removing a yarn package, more especially a cop, from a winding machine spindle
IPC: B65H67/04
Filed: 1956-02-20
Abstract: 795,115. Winding yarns. OFFICINA MECCANICA BRUEGGAR SOC. PER AZIONI. Feb. 20, 1956 [Feb. 21, 1955], No. 5115/56. Class 120(2) A device for removing a yarn package more especially a cap, from a winding machine spindle comprises a lead screw- and-nut mechanism adapted to be actuated on completion of a package to displace the spindle and remove it from the package, which is restrained against movement by reaction of a conical portion thereof against an associated roller. A spindle 10 mounted in a carraige 12 slidable by means of rollers 14 on guides secured to the machine frame moves axially against the action of a counterweight during building up of the cop. Due to the reaction against end-forming rollers R, the carriage 12 is brought towards a bush 62 locked by a screw 64 in predetermined position on a shaft 60. When the cop reaches a predetermined position a block 46 slidably mounted in a cylinder 48 on the carriage 12 strikes a spring pusher 66 on the bush 62 and the block 46 slides into the cylinder 48 against the action of a spring. This causes a pinion 42 and disc 36 to rotate and, by means of pins 28, 30 in spiral slots 32, 34, of the disc 36, the two halves of the nut 22, 24 are brought into engagement with the screw 20, which is constantly rotated. The spindle 10 is stopped and the carriage 12 driven back by rotation of the screw 20, thus withdrawing the spindle from the cop. The carriage 12 moves back to a predetermined position, where a nose 56 on a spring catch 54 strikes an abutment 58 and raises the catch 54, thus freeing the block 46 from the cylinder 48 and allowing it to slide so'that the rack 44 drives the disc 36 to disengage the halves 22, 24 of the nut. This stops the backward movement of the carriage 12 and a new winding operation can begin.

Title: Improvements in or appertaining to strong boxes, jewel cases and the like
IPC: G08B13/14
Filed: 1922-02-22
Abstract: 197,439. Sutton, C. J. Feb. 22, 1922. Theft and like alarms.-In jewel cases and the like which contain devices for giving an alarm in movement, a plate covering the keyhole is pivoted on an axle extending through the wall of the case, said axle having fixed on it a lever or wheel provided with parts which actuate a lever on the inside of the case to give an alarm. The lower edge of this plate may be on a level with the lower edge of the box and broadened out so that the box must be tilted to move the plate, thereby causing the alarm to be given by means of any usual device. A lever, Fig. 11, or a wheel 3, Fig. 2, may be arranged inside the box on the axle of the plate 1 and carry studs 3d or 3a which on turning of the plate press a lever 5 on to contacts to close an alarm circuit. The wheel may be a ratchet, held from turning in one direction by a pawl 4. When the plate is turned the studs 3<a> lock the setting on lever of the ordinary alarm arrangement against movement. In modifications, a single spring contact piece is disposed on the wheel 3, or the plate slidable and a sliding member attached to it inside the box depresses the lever to close the alarm circuit. The arrangements for giving an alarm on the. box being tilted may be as shown in Fig. 6, in which a pendant 13 when displaced gives an alarm and may be reset by the lever 7. The lever moved by the cover plate may be arranged to displace the pendant. According to one Provisional Specification, a projecting piece on the key when inserted into the lock may release the alarm.

Title: An Improved Valve Mechanism.
IPC: F15B13/00
Filed: 1968-02-01
Abstract: 1,175,163. Valves. MEKANPRODUKTER HANS HOLM A.B. 1 Feb., 1968 [10 Feb., 1967], No. 5143/68. Heading F2V. [Also in Division G4] A valve which can be optionally adjusted to give an OR-function or an AND-function, comprises two inlet ducts 25, 23 and 26, 24, two outlet ducts 29, 27 and 30, 28, both of which outlets lead to a service line 31, and a valve member 11 which is adapted for controlling the flow between the various ducts, the valve housing being formed of two abutting parts 4, 5 of which the latter has a closed bore 6 formed therein for accommodating the valve member 11. In the state of the valve shown, wherein the outlet 29, 27 is blocked by a rubber membrane 32, fluid pressure applied from corresponding impulse valves, not shown, to one only of either one of the inlets does not result in any pressure transfer to the line 31 in view of the blocked outlet. If, however, pressure pulses are applied simultaneously to both inlets then that from inlet 25, 23 serves to move the valve member against its spring bias so permitting the inlet 26, 24 to communicate with the outlet 30, 28 via an annular space 15 defined by the valve member. The valve thus gives an AND-function. Alternately, if the seal 33 and membrane 32 are interchanged, so blocking outlet 30, 28, then the inlet 26, 24 is in communication with the outlet 29, 27, via the annular space 15, and the inlet 25, 23 can be brought into communication with the outlet 29, 27 if the pressure in the inlet is sufficient to move the valve member upwardly, the valve thus giving an OR-function. In a modification, a recess may be provided between the two housing parts to accommodate seal 33 and membrane 32, which would then be formed integral with one another, and so to facilitate the change over from one function to the other by simple pivoted movement of the integral seal and membrane.
