Abstract: 1277408 Mountings for switches or instruments in motor vehicles JOSEPH LUCAS (INDUSTRIES) Ltd 2 Oct 1969 [15 Oct 1968] 48842/68 Heading B7H [Also in Division H1] A switch 16 or instrument is pivotally supported by lugs 17 to a frame 11 attached to a horizontal panel of a dashboard of a motor vehicle and is retained in its normal position secured within a recess in the panel by a front ribbed portion 18 which interengages with a corresponding rib portion 14 on the front edge of the recess. Normally during usage the effert exerted by manual manipulation is only sufficiently adequate to operate the switch or instrument. However, in the event of undue pressure being applied to the front of the switch or instrument due to a passenger being thrown against it as the result of a collision the force then exerted causes the switch or instrument to become disengaged from its frame, the rib portions 14, 18 being forcibly separated such that the switch or instrument swings downwardly and away from the passenger about the pivot lugs 17 thereby reducing the possibility of injury to the passenger. The switch or instrument may be initially mounted in the frame by sensing it through the recess from the top of the frame prior to the latter being secured in position. Alternatively the frame may have additional slots extending through the side edges of the recesses through which the lugs 17 are passed from beneath the frame and are subsequently engaged in recesses in the side edges, the front rib portion 18 simultaneously engaging above the rib portion 14 on the frame.

Title: Line at a time mosaic printers
IPC: B41J5/44
Filed: 1971-10-28
Abstract: 1365345 Printers CREED & CO Ltd 28 Oct 1971 50078/71 Heading G4H In a mosaic printer, an action store accumulates a predetermined plurality of character signals or a predetermined plurality of short lines of characters before printing starts, further character signals which arrive during printing being stored in a collection store. The characters arrive at 1 (or on a single line) and are passed via lines la, and gates 3, 5 to an action store 7, a counter 11 driven by clock-pulses accompanying the characters at 2 keeping a tally of the storage positions used. A "new-line" signal is detected at 12 to prevent its own entry into store 7, and cause the tally count at 11 to be saved in a tally store 16. When the tally counter 11 reaches capacity (store 7 full), a signal at 17 starts printing, and subsequent characters at 1 are gated 21 to a collection store 23 instead of to the action store 7. A reversible counter 25 is incremented to keep a tally of the positions filled in the collection store 23. The action store 7 (which is a shift register) recirculates via path 27, the circulation being timed by clock pulses at 28 from the printer which drive counter 11. Transfer gates 36 between action store 7 and a mosaic pattern generator for the printer are enabled under control of a comparator 29 responsive to counter 11 and tally store 16 to gate out the characters for one line (which need not be a full line), this being done as many times as there are rows in the mosaic, as determined by a mosaic row counter 38, after which the next line is read out similarly, and so on until all the lines in action store 7 have been printed, when tally store 16 is empty (all its contents having been used by comparator 29). This is detected at 40, to cause the contents of collection store 23 to be transferred at high speed to action store 7 with incrementing of counter 11 and decrementing of counter 25 until the latter is zero, after which operations proceed as before. As a modification, the collection store can be allowed to almost fill before printing begins so that when the action store contents have been printed the collection store will be full, thus avoiding stopping of the record surface. To prevent character loss at the input when a number of short lines are being printed (the printing time being proportional to number of lines, irrespective of their length), printing may begin on recognition of a predetermined number of lines in the action store even if this is not full, or alternatively character signals in the action store which have been printed could be replaced by fresh character signals from the collection store. The action store 7 could be a random access store instead of a shift register.

The powder container 16, Fig. 1-which may be of polyethylene-of a powder-fed flame spraying torch 12 has at least one movable wall such that inward collapse of at least part of the container takes place upon withdrawal of the powder. In the embodiment shown, the wall 38 is of bellows formation and the container is secured to the torch through a connector cup 20 the connection between the container neck 32, Fig. 3 (not shown) and the cup being effected by a bayonet type coupling 30. In a further embodiment the entire wall of the container is of bellows formation and a plug and cap device, Fig. 9 (not shown), is provided to seal the contents against contamination when the container is not fitted to the torch. In this embodiment the wall 38 is extremely flexible such that it may collapse completely into the container to an extent allowed by the remaining powder. In a modified form of the container of Fig. 1 a tube is located in the neck such that it extends into the container to within a short distance from the wall 38. The container 16c of Fig. 13 (not shown), comprises an air-filled space 58c separated from the powder filled space 60C by a flexible diaphragm 56C. In the container 16D of Fig. 15 (not shown), on the other hand, a wall 38D is made slidable, pistonlike, within a cylinder 16D. Marks 66D are provided as indicators denoting powder level within the container. The container 16E of Fig. 17 (not shown) comprises a flexible plastic powder filled sac locked within a rigid tube 68E the locking being effected by making the connector cup 70E from a resilient material and forming the sac with a flanged turn-over end 71E. The tube 68E is formed with a' flange 74E such that forceful insertion of the latter into the sac end 71E and the cup 70E causes a flange 76E on the cup to snap-over the assembled flange 74E and end 71E. If the tube and sac are of transparent plastic material the amount of powder in the container at any time is readily discernable.

Abstract: 1464480 Separating aldehydes RUHRCHEMIE AG 8 Dec 1975 [14 Dec 1974] 50239/75 Heading C2C A process for the recovery of an n-aldehyde from an n-/i-aldehyde mixture comprises treating the mixture in the presence of a solvent with an alkali metal bisulphite in an amount not more than that which is stoichiometrically equivalent to the n-aldehyde in the mixture, separating the resulting precipitated bisulphite addition compound, washing it and decomposing it to the n-aldehyde, e.g. by addition of formaldehyde, n- or i-butyraldehyde. The initial aldehyde mixture may be derived from the hydroformylation of a terminal olefin. In one variant, less than the stoichiometric amount of bisulphite is used initially and the filtrate after separation of the precipitate is treated with excess bisulphite and the resulting precipitate, together with aqueous bisulphite, is used to precipitate the n-aldehyde from a further batch of the isomeric mixture. Examples separate mixtures of 2-phenyl-propanol-1 and 3- phenylpropanol-1 (from hydroformylation of styrene) and n- and i-C 11 - and C 13/15/17 -Oxo alcohols.

Filed: 1972-11-07
Abstract: 1414507 Controlling control sheet thickness OWENS-ILLINOIS Inc 7 Nov 1972 [9 Nov 1971] 51309/72 Heading B5A The thickness of an extruding foaming thermoplastics sheet and the molecular orientation thereof, e.g. for use in shrink wrapping applications, is independently regulated at locations across its width by streams of cooling gas, e.g. air, or carbon dioxide, directed against the sheet downstream of the die and which streams are disposed along the length of the orifice, on either or both sides of the sheet, and are independently manually or automatically controllable in respect of the temperature and/or flow rate of the gas. Increased cooling produces decreased thickness with increased density, and vice versa. The particular description relates to polystyrene of a thickness of 0À020 inches, which can be varied by 0À002 inch using cooling air pressures of 1 to 12 ounces per sq. inch. Various other thermoplastics are specified as well as nucleating agents, and blowing agents which can either be injected in the extruder or incorporated prior to extrusion. In the Figs. 2 and 3, embodiment, a tube 16 is extruded from the lips 14, 15 of a heated die and is drawn around an internal sizing mandrel (19), Fig. 1 (not shown), and slit into two separate sheets in passage to drawing rollers, the tube being diametrically expanded between the die and mandrel by internally circulating low velocity air admitted and withdrawn via the sizing mandrel. The cooling streams 35 are each directed on to the extrudate 16 from circumferentially aligned channels, e.g. 24a to 24e, which are spaced 10 degrees to yield 36 channels for an 11 inch diameter die. A plurality of such channels may be provided in axial alignment between adjacent discs 24-28. The channels are each provided with a gas flow rate damper, e.g. 36-39 which is controlled independently, either manually or by the sheet thickness measuring apparatus described in Specification 1,372,501. The cooling effect of the gas streams may be enhanced by vacuum withdrawal of the gas, via passageways 52-54 which may be circumferentially divided and provided with needle valve controls in correspondence with channels 24a-24e &c. Instead of the passageways 52- 54, circumferentially alternate ones of the channels 24a and 24e may be employed for cooling gas delivery and vacuum application. The extruding tube may be cooled additionally, or alternately, internally by the apparatus of the Fig. 4 embodiment providing cooling gas channels 68-71, and vacuum passages 72- 74, arranged circumferentially and independently controlled as in the Fig. 2 and 3 embodiment. The apparatus is supported from the sizing mandrel 19 and heat insulated from the die by material 93.
