Abstract: 771,612. Conveyers; terminals for overhead ways; gripping devices. BAKER PERKINS, Ltd. Sept. 6,1955 [sepa6,1954], No. 25817/54. Classes 78 (1) and 78 (4). Bread or cake tins 12 are transferred between bakery units 14 and 14a by a gripping mechanism 3 which travels along a gantry 1, is lowered at the ends thereof to pick-up and deposit the tins, and is driven in timed relation with the conveyers in units 14, 14a. As shown in Fig. 1, the mechanism 3 is suspended from a carriage 2 which is provided with rollers 5 and is traversable along the gantry by a rack- and-pinion mechanism 7, 8 driven by a motor 10. The carriage is adapted to be moved off each end of the gantry on to trackcarrying platforms 11, which are raised and lowered by levers 15a, and thrustors 15 located either above or below the bakery units. Operation of motor 10 and thrustors 15 is controlled by trip mechanism (not shown). Pairs of arms 30 of the gripping mechanism are actuated through links 42 when an arm 35 is swung about a pivot 36 by a fork 46 which engages a roller 52 on arm 35, and which is moved by the engagement of a lever (not shown) on shaft 47 with fixed abutments (also not shown) at the loading and unloading stations. The lever 35 is acted upon by an over-centre spring 40. In a modification (Fig. 7, not shown) the platforms are raised and lowered by linkages actuated by cams driven synchronously with the conveyer drive mechanisms. In another modification (not shown) the platforms are raised and lowered by screw-and-nut mechanisms. Fig. 5 shows an arrangement in which the gantry 1a is provided with downward extensions 60, 61 which allow the carriage 2a to move directly to the loading and unloading stations under the power of a motor-driven pinion (not shown). The carriage is freely suspended from a single pair of guide rollers 5a. In Fig. 6 (not shown) the gantry is shaped as shown in Fig. 5 but the carriage is moved between the two bakery units by an endless chain guided to follow the path of the gantry. Specifications 700,976, 700,977, and 702,663, [all in Group VI], are referred to.

Abstract: 906,584. Valve frequency selective amplifying circuits; valve oscillating circuits. STANDARD TELEPHONES & CABLES Ltd. July 17, 1961 [July 21, 1960], No. 25856/61. Class 40 (6). An amplifier or oscillator comprises a cavity resonator operating in a radial mode and a plurality of valves having their grids and anodes connected to its end walls, the valves having their electrodes on a common circumference with its centre at the axis of the resonator and being spaced equidistantly round that circumference, and a tuning slug located at the axis of the resonator. In an embodiment two valves 4, 5 are provided, set across a cylindrical resonator 1, the anodes being coupled to the end-plate 2 by means of flanges which form capacitors with the end-plate 2 and using rings 8, 9 of dielectric material. The grids 10, 11 are directly connected to the second end-plate 3; the arrangement is tuned by means of an adjustable slug 12 on the axis of the cylinder. Output is taken off via a coupling loop 13. An input is applied to the cathodes by means of a second resonator comprising end-plate 3, a cylindrical wall 14 and a bottom end-plate 15 to which the cathodes 16, 17 are coupled by means of extension tubes 18, 19 and capacitors 20, 21. This cavity is provided with a tuning slug 22 and is of smaller diameter than the first cavity, so that the grid-cathode paths of the valves may be located at points of low impedance; this is made possible by adjustment of dimension d or by loading the centre of the cavity with capacitance. Input is applied by means of a coupling loop (Fig. 4, not shown). In a frequencymultiplier application the second cavity may be replaced by a circuit with humped constants. In an oscillator, the two resonators are coupled by a link circuit.

Title: Production of cyclic di-p-xylylene
IPC: C07C2/00
Filed: 1965-06-21
Abstract: Cyclic di-p-xylylene is obtained by pyrolysing xylene in the presence of steam to obtain a stream containing p-xylylene radicals which is cooled to 450-800 DEG  C., conveyed to a first spray zone while thermally and physically isolating the stream from non-wetted surfaces which are maintained below 350 DEG  C., contacting the stream with a spray of quench liquor which is a solvent for p-xylylene radicals, whereby p-xylylene radicals are dissolved and condensed and the stream is cooled by vaporization of the quench liquor, contacting the effluent with further spray of quench liquor in a second quench zone to remove residual p-xylylene radicals, maintaining all surfaces in the first and second spray zones wet with quench liquor and the temperature of the quench liquor above the condensation temperature of the steam and recovering cyclic di-p-xylylene from the quench liquor. Preferably p-xylene is pyrolysed at 800-1000 DEG  C. and then cooled to below 800 DEG  C. by injecting steam.  The transition zone between this and the quench zone preferably comprises a thermally insulated conduit leading into a conical entrance to a downcomer leading to the spray zones, this conical inlet being continuously washed with quench liquor. Alternatively a porous walled conduit is used and vapour passed through the wall to form a continuous vapour barrier.  Preferred quench liquor is p-xylene; also mentioned are o- and m-xylene, toluene, cumene, benzene, methyl-naphthalene, o-dichlorobenzene, 1,2 - di - p - tolylethane, di-phenylmethane and heptane.  Product is recovered from a bleed stream of quench liquor, the remainder being recycled, to maintain a di-p-xylylene concentration in the circulating liquor below 10%.

Abstract: <PICT:0715769/III/1> In apparatus for indicating the quantity of or detecting a particular constituent in a fluid which apparatus comprises an inflow and outflow plate a passageway for fluids in each plate positioned to communicate one with the other when the plates are in assembled relation, a continuously driven element operable to draw a sensing medium between the plates and laterally across the openings of the communicating passageways, means on the plate to hold them in proper relative position and to guide the sensing medium, and means associated with one passageway to produce a flow of the fluid to be analysed through the passageway associated with the inflow plate and to the sensing medium, one of the plates presses against the other so that the sensing medium acts as a gasket and thereby eliminates leakage into the fluid stream from the atmosphere.  The apparatus shown comprises an inflow chamber 10 which is mounted above an outflow chamber 11 and located by projections 23 engaging in slots 24.  Conduits 12, 13 are connected to these chambers, conduit 13 being connected through pipe 18 to a suction pump so that fluid is drawn through conduit 12, e.g. from a combustion chamber.  Through the gap between chambers 10, 11 and thus across the path of the fluid a filter tape 25 is fed continuously by rollers 27 this tape being guided by the projections 23.  Hence, if smoke or other contaminant is contained in the fluid, a deposit 26 will appear on the tape 25. The lower surface of chamber 10 and the upper surface of chamber 11 have slots in which are placed inserts 21, 22 with rectangular slots therein; a series of such inserts with slots of different sizes are provided so that the area of filter tape exposed to the fluid in unit time may be regulated.  Conduit 13 is also connected through a bellows 30 with a switch 32 for sounding an alarm (not shown) when the deposit on filter tape 25 reaches a certain amount.  The filter tape 25 may be chemically treated (e.g. with iodine) to give a colour change if a certain constituent (e.g. starch or sulphur) is present in the fluid.
