Patent GB-1600783-A (GB)
Title: Extrusion head
IPC: B29C48/12
Filed: 1978-03-08
Abstract: The extrusion adapter includes a breaker plate (16) placed between the tip (17) of the extruder screws and the pressure-equalising chamber (18). The downstream side of this breaker plate, coming before the pressure-equalising chamber, has a plane face whereas the upstream side has a recess which has the shape of a cone whose apex (opening) angle is the same as that of the tip of the screws. This breaker plate is formed by two series of parallel-axis channels (20).   This extrusion adapter is intended especially for equipping a line for manufacturing products in the form of sheet (strip) by the cooking-extrusion-expansion process, in particular for the manufacture of food products. <IMAGE>

IPC: B65B51/06
Filed: 1961-03-14
Abstract: 921,104. Applying adhesive strips. JAGEN. BERG-WERKE A.G. March 14, 1961 [April 5, 1960], No. 9261/61. Class 73. Refers to apparatus for securing together the corners of a box by adhesive strips. The strip 15, Fig. 1, is fed from a roll 14 via rollers 16, 17, 18 by a driven roller 19 and counterroller 20 shaped as shown in Fig. 4 to bend the strip to a V-shape, the strip then being severed by means of a stationary knife 23 and a knife 24 secured to the front side of a movable pressure jaw 4 located on a double-armed lever 6. The severed portion of the strip is held to the jaw 4 by movable tongues 25, Figs. 1, 6 until the pressure jaw 4 pivots downwardly to press the strip 15 on to the box 2 located on a stationary jaw or anvil 3. The intermittent movement of the jaw 4 is effected by a cam 8 and cam follower 9 while the drive for the feed roller 19 is also effected by the cam 8, a cam follower 28 on one end of a two-armed lever 26 and a cord or chain 29 which engages the other end of the lever 26 and passes over rollers 30, 27 and is connected to a fixed point of the apparatus via the hub of the roller 19 and a spring 33. The pivot axes 5 of the lever 6 is eccentrically disposed to provide for adjustment of the setting of the jaw 4. The jaw or anvil 3 is supported on an elastic component 10 and is secured to the holder 11 by a pin and bore arrangement 12, 13 which permits limited lateral play of the jaw 3. A heating element may be located in the jaw 4 for use with thermoplastic adhesive strip.

Patent GB-837796-A (GB)
Title: Improvements relating to the recovery of fluorine from fluorine-containing waste gases
IPC: A47J47/12
Filed: 1958-03-25
Abstract: Fluorine values are recovered from waste gases deriving from the electrolytic production of aluminium in a fluoride-containing fused salt bath, which gases also contain sulfur dioxide, by washing the gases with water until a 3% to 10% hydrofluoric acid solution is obtained, and then reacting this solution with aluminium-and sodium-containing materials to precipitate a double fluoride of sodium and aluminium.  The aluminium- and sodium-containing materials are selected from the group consisting of sodium compounds, aluminium compounds, and their solutions, which are soluble in the hydrofluoric acid solution, and also metallic aluminium, for example in the form of dross or skimmings.  Thus, a solution of sodium aluminate may be added to the hydrofluoric acid solution, or aluminium hydroxide or dross or skimmings may be added to form aluminium fluoride, to which is then added a sodium fluoride solution to precipitate the double fluoride.  If the aluminium fluoride contains excess HF, the sodium fluoride may be formed in situ by adding for example sodium hydroxide or carbonate.  The sodium fluoride solution may be obtained by leaching wastes from the electrolytic furnace and reacting the liquor obtained with HF, or the liquor may be added directly with the HF-AlF3 solution.  Alternatively, the sodium fluoride solution may be obtained by washing part of the waste gases with a solution of sodium carbonate or hydroxide or with the furnace waste leach liquor previously referred to.

Title: Fire alarm signal systems
IPC: H04M11/04
Filed: 1948-04-06
Abstract: 647,852. Fire alarm systems. TATE, T. J. April 6, 1948, No. 9631. [Class 40 (i)] In a fire alarm system applicable to a conventional PBX telephone installation, each extension pair 11, 12 is bridged adjacently to its telephone instrument 15 by a thermallyoperated switch 18 closing at, e.g. 135‹ F. and in series with an automatic interrupter 20. The rise of temperature due to an outbreak of fire at the extension, closes 18 and loops the extension pair to intermittently operate the extension call-lamp or signal at the PBX, 10. In a modification (Fig. 2, not shown), duplicate thermal switches may be used with one interrupter to operate over the telephone pair and an independent pair.
Patent GB-935474-A (GB)
Title: Improvements in or relating to key controlled switching devices
IPC: H01H36/00
Filed: 1960-03-18
Abstract: 935,474. Magnetic switches. STANDARD TELEPHONES & CABLES Ltd. March 18, 1960 [March 21, 1959 ; March 26, 1959], No. 9666/60. Class 38 (5). [Also in Group XXXIX] On depressing a key of a keyboard switching device at least one permanent magnet is moved relative to an adjacent reed switch to close the reed switch. Strips X1, X2, X3, X4, Y1, Y2, Y3, Fig. 1, preferably of non-magnetic material are fastened to a base-plate 1 by springs 2, 4 and are held in a position of equilibrium by permanent magnets 3, 5 which are fixed to side walls to attract the ends of springs 2, 4. The strips (except for strip X1) carry permanent magnets 6 for actuation of reed switches a, b . . . i (a not shown) each comprising two magnetic reed contacts in a sealed protective envelope. Each key is arranged at the intersection of two strips and, when depressed, engages profiles in the two strips at the intersection and displaces such strips longitudinally against the action of springs 2, 4 to bring at least one magnet 6 into proximity with an associated reed switch a, b . . . &c. to operate such reed switch. Alternative arrangements.-Rods X, Y, Fig. 2, are used as coupling elements and one of each is rotated on depressing a key, projections 13, 14 on the key engaging projections 11, 12 on the rods. At one end of each rod is a permanent magnet 16 which, on depressing an appropriate key, is rotated from a short-circuit position in a shunt 17 to a position, adjacent flux-deflecting members 15, in which it operates a reed switch a. A spiral spring (not shown) provides the return motion. In a third arrangement a housing 29, Figs. 4, 5, carries a support 32 on which are mounted four reed switches 25, one above the other. Pivotally mounted arms 23 have extensions which carry permanent magnets 24 for actuation of the switches 25, the arms being moved by movement of keys 21. Springs 26 restore the arms 23 and springs 36 restore the keys 21. Movement of any key 21 also provides operation of a common reed switch 25<SP>1</SP> by movement of permanent magnet 241 through slide 27, Fig. 6. Slots 34 in the slide 27 prevent intercoupling of the arms 23 and consequent movement of all magnets 24 when only one key is depressed. Reed switch 25<SP>1</SP> is normally closed, and is released when any key is operated but, by mounting magnet 24<SP>1</SP> higher up, the reverse condition could be obtained. Reed switches 25 may be made to close at the end of travel of the arms 23 but, with a larger travel, they may be made to close momentarily during the key depression and to be released while the key is fully depressed.

An unloading, loading and tooling operation is performed at the station F, Fig. 2, in addition to the normal operations at the remaining stations; the former two operations are effected by the cross-slide 4 reciprocated by cam and lever mechanism 27, 28 and the associated longitudinal slide 6, mounted on the cross-slide 4 and reciprocated by cam and lever and rod and lever mechanism 14, 15, 16, 17, Figs. 1, 2 and 5. The blanks 11 are fed down the shoot 1 which is kept closed by an associated part 26 of the cross-slide until the latter is in position for the commencement of a feeding operation, the blank falls into a recess 9, Fig. 5, in the auxiliary slide 6 and is supported also by a cradle lever 7 spring-urged against a stop 7a to maintain it in correct supporting alignment with the recess 9. The cross-slide is moved inwards to bring the blank into line with the chuck 20 and then the auxiliary slide 6 is moved longitudinally to feed the blank into position against an ejector 22 which is thereby compressed and remains so when the chuck is closed on the work. The auxiliary slide is then moved axially away from the chuck and the cross-slide withdrawn, the cradle-lever rocking downwardly under the blank to free it therefrom. The ejectors 22 are interchangeable in the jaws 22a of the known spindle heads 21.
