Filed: 1970-03-04
Abstract: 1305422 Conveyers; shoots HAUNTWERKE KORBER & CO KG 4 March 1970 [4 March 1969] 10438/70 Headings B8A and B8S A magazine 1 of a cigarette machine (not shown) is fed by a carrier 19 which reciprocates horizontally between positions A, B, the carrier being adapted to receive trays 75 which are fed by conveyer belts 76, 77 on to a vertically movable platform 78. After cigarettes are transferred into the carrier 19, the empty tray is discharged on to conveyer belts 79, 81 by a pusher 88. Carrier 19 is movable along rods 17, 18 by nut and screw means 68, 69 and has a base 46 slidable in grooves 48, 49. Projections 47 on the base are so dimensioned as to be slidable in grooves 119 formed in the base of tray 75. Depending guides 24, 25 are movable transversely of the carrier and may be received within grooves 118 of the side walls of the tray 75. The platform 78 is operated by nut and screw means 102, 103, 104, 105. In operation, as soon as the level of cigarettes in the magazine 1 falls below a light control 7, the carrier 19, already filled with cigarettes from a preceding cycle, is moved to position B, and the base 46 automatically retracted by a spring 57 to the position shown in the Figure, so that the cigarettes are released into the magazine. After the guides 24, 25 have been moved outwardly, the carrier 19 is returned to position A, and the guides again restored to their inner position. A full tray having been fed on to the platform 78, the latter is raised and the tray is received in the carrier, with the guides 24, 25 moving into the grooves 118 of the tray. A pneumatic cylinder 51 then moves the carrier base 46 towards the magazine and, with the cigarettes in the tray now resting on the base projections 47, the base is secured by latch means 63, 64. The tray, now empty, is lowered by the platform until level with the conveyer belts 79, 81 whereupon the pusher 88 transfers the tray on to the conveyer belts. The platform then completes its downward travel ready to receive a further filled tray. An electro-pneumatic control system is described and illustrated, Fig. 2 (not shown).

Filed: 1953-04-17
Abstract: 758,449. Tunnel furnaces. GIBBONS BROS., Ltd. July 19, 1954 [April 17, 1953], No. 10522/53. Class 51(2). In a tunnel furnace of the multiple-track tmiflow or counter-flow type, passageways for the articles to be treated are arranged in vertical rows 11a-11d heated in the firing zone by heating flues 17a-17e extending between a combustion chamber 14 and a waste gases header 20, each flue being associated with its own row of burners 16. The header 20 extends longitudinally on either side of the firing zone to further sets of vertical flues 18 and 19 respectively corresponding to the flues 17a-17e and leading to further headers 21 extending across the furnace and formed at each end with vertical outlet ducts for the waste gases, Fig. 3 (not shown). The flues 18, 19 may be given a zig-zag configuration and the header 20 may be so partitioned as to lead gases from the inner members of the flues 17 to the outer members of the flues 18, 19. A third set of waste gases flues may be provided in which case they will be dis. posed near the ends of a counterflow tunnel or near the exit end of a uniflow tunnel in which latter case the firing zone will be arranged near the furnace entrance. The outer heating flues 17a and 17e may have a greater cross-sectional area than the inner flues 17b-17d. Valves, dampers or the like may be provided in operative association with the burners or heating flues and made thermostatically responsive to the temperature in the particular passageways heated by the flues concerned. The outer passageways may have a more extensive heat exchange with the heating flues than those in the centre e.g. by the provision of a tertiary or additional traverse of the heating flues in the outer regions.

[Also in Division G4] A record card is made of opaque plastics material and carries a magnetic coating, on one face or between two sheets, which contains a magnetic oxide of low coercivity with "noise" recorded therein and a magnetic oxide of high coercivity with a number of pulses recorded therein. Boxes.-A packet having flaps 556 is folded along dotted lines 557 to form "box-girder" reinforced edges. The packet is coated with self-sealing adhesive in the dotted areas. Two slots 558 display the contents, e.g. bank-notes. A coloured marking-strip is placed at one edge to facilitate the correct stacking of packets. The packet is erected by a shallow rigid tray having projections to receive the slots 558 of the packet, and walls which turn up the packet sides as the blank is inserted, by machine or by hand. Reciprocating conveyers.-Packets are stacked in a container 501 of a money-dispensing machine (see Divisions G4-G6), having a hinged rear wall 502, and are supported on a first trolley 509 (Fig. 6). Trolley 509 and a trolley 510 are reciprocated in turn by levers 515 and 525, respectively (Fig. 7), pivoted at 516 and 526, which are controlled by a cam 511 through their co-operating pins 519 and 527. Cam 511 is rotated by the motor 512 (Fig. 6) which is switched off by a switch 529 after one revolution of the cam by switch-arm 530 moving into a depression in the cam. Trolley 509 is withdrawn leftwards from the stack (Fig. 6) which falls on to the floor of the container 501, and while returning it pushes the bottom packet through slot 508, under restraining brushes 550, on to trolley 510. Trolley 510 then moves rightwards (Fig. 15), causing a rod 540 mounted beneath the trolley to be moved longitudinally by a cam 543. A pin 541 on the rod 540 engages in a helical groove 542 in a pivoted plate 538, thereby raising the plate and the carton 532. As the trolley 510 returns, the packet is transferred to a platform 545 constituting the base of a delivery recess for removal by a customer. The recess may be closed by a hinged cover. The platform edge is movable vertically and, or alternatively, may have a longitudinal slot to accommodate the raised plate 538. The plate is lowered as the rod 540 meets a guide 549 as returning. Rotation of the cam 511 is prevented by a pin 551 until the pin is withdrawn by a solenoid 552 (Fig. 6).

Title: Improvements in and relating to the production of ammonium sulphate
Inventor: RINISLAND KLEMENS
IPC: C01C1/242
Filed: 1960-03-25
Abstract: <PICT:0874061/III/1> Coarse crystals (as defined) of ammonium sulphate are continuously produced by passing a stream of ammonia-containing vapour through a 3-10% strength dilute sulphuric acid bath maintained at 80-90 DEG C., passing a stream or streams of air upwardly through a confined zone of the ammonia saturated acid to promote growth of ammonium sulphate crystals therein and extracting crystals from the bath, further acid being added to the bath to maintain the desired acid concentration, the crystals being constantly circulated in the confined zone by the air stream or streams until they reach a sufficient size or weight to sink therein and the vapour, after ammonia removal, being recovered separately from the air stream or streams.  In operation, a cylindrical vessel 11 having a frustro-conical closed base 12 is filled to level 15 with sulphuric acid and ammonia-containing vapour, e.g. retort or coke oven gas, from conduits 19 is passed through the acid to exit as ammonia-free vapour through outlet 27.  Ammonium sulphate crystals forming in the bath are kept in motion by a flow of air through nozzle 22 upwards within the space 29 of the inner vessel formed by cylinder 14.  Crystals and liquor caused to flow by the air stream flow in the direction of arrows 30 and 31 around deflector cylinder 25.  The fresh acid is added through conduit 21. Crystals under continued motion in space 29 grow until they are of sufficient size or weight to fall to the bottom 12 of the vessel 11 where they are removed through port 13.  Mother liquor subsequently separated from the crystals may be returned to the acid bath through conduit 21. Air streams passing up through space 29 exit through outlet 24.

Patent GB-1017806-A (GB)
Title: Esterification process
Inventor: ENSOR GORDON ROY
IPC: C07C69/54
Filed: 1963-03-28
Abstract: Acrylic acid esters are produced by contacting the vapour of the acrylic acid and the vapour of a monohydric alcohol with an acid esterification catalyst, especially at a temperature of 100 DEG  to 180 DEG  C., and especially using as catalyst sulphuric acid, benzenesulphonic acid or toluenesulphonic acid.  A preferred feature is the use of a solid support for absorbing the catalyst, especially in a granular form for use as a catalyst bed.  An inert gas stream may be employed to convey the reaction products from the reaction zone.  Particularly suitable starting materials are acrylic acid itself or an alpha-alkyl acrylic acid, namely methacrylic acid.  It is also possible to impregnate the solid support with an ester of the catalysts such as, for example, dimethyl sulphate, which hydrolyses to yield the catalyst proper after primary contact with the reactants.  A modification of the reaction employs the first part of the catalyst bed as a pre-heater to effect volatilization of the reactants. The examples describe the production of methyl methacrylate using toluene sulphonic acid on a support and sulphuric acid on a support. A stream of nitrogen is used as a diluent in both the examples.
