Abstract: 1485830 Envelopes DISPLAY CORP INTERNATIONAL 21 Oct 1974 [27 Feb 1974 6 June 1974] 37806/76 Divided out of 1485829 Heading B8K An envelope 38 for carrying a flat article such as a road map and which is an example of one of several envelopes which are placed in a stack in a dispensing device for the sale of such articles, comprises a pair of flat side panels 60, 62 which are connected along one side edge 64 and along the opposite end edges 66, 68 to form a pocket which is closed at three sides and open at one side to receive a folded road map 40. Centrally located in each of the panels 60, 62 is an aperture 70 which is engaged by part of the dispensing mechanism (80, 82) of the dispensing device for movement through a dispensing slot (58), Fig. 2 (not shown). An alternative embodiment of envelope is shown in Figs. 9 and 10 (not shown).

Title: Internal combustion engine having an exhaust gas recirculating system
IPC: F02M25/07
Filed: 1974-09-02
Abstract: 1483355 Controlling exhaust gas recirculation FORD MOTOR CO Ltd 2 Sept 1974 [24 Sept 1973] 38243/74 Heading F1B An I.C. engine comprises a carburetter having an induction passage 18 containing a Venturi 22, a passage 44, 42, 46, 48, 50 connected to recirculate exhaust gases from exhaust manifold 38 to intake manifold 30, the passage containing a valve 56 responsive to both inlet manifold vacuum and Venturi vacuum and being movable between open and closed positions in dependence thereon by a servo 58 having a movable member (diaphragm 86) acted on on one side by the manifold vacuum and on the other side by the Venturi vacuum. The Venturi vacuum depends on the air flow to the engine and hence on the engine speed and acts in a chamber 80 whereas the manifold vacuum depends on the opening of throttle valve 24 and hence on engine load and acts in a chamber 70. Chambers 68 and 82 are open to atmospheric pressure and the diameters of diaphragms 68, 86 and 79 separating the various chambers are chosen so that a given depression at the Venturi would result in a force ten times as great being exerted on the valve 56 as would be exerted if the same depression occurred in the inlet manifold, to compensate for the fact that during part-throttle operation, the Venturi depression is much smaller than the inlet manifold depression as illustrated in Fig. 3 (not shown). At idle the manifold vacuum is high enough to lower valve 56 so that the valve land 92 closes on to seat 96 preventing exhaust gas recirculation and at maximum speed with wide open throttle recirculation is prevented by the valve's being raised until land 94 closes on to seat 98. At intermediate loads and speeds, recirculation is permitted.

Patent GB-344550-A (GB)
Title: Process for the electric purification of gases, in particular furnace gases
IPC: B03C3/014
Filed: 1929-12-16
Abstract: In the electrical purification of gases, in particular furnace gases, the gases, prior to entering the electro-filter, are first heated and then moistened by the injection of a small quantity of liquid, such as water, so that the gases possess a conductivity suitable for the purposes of separation, but are not cooled below the dew point.  The gases may be heated directly or indirectly e.g. by a gas flame, or in the case of combustible gases by an air flame.  In an example, furnace gases at a temperature of 50 DEG  C. and with a moisture of about 50 gr. per cubic metre, require a moisture content of 75 gr. per cubic metre to obtain good precipitation.  As by the introduction of 25 gr. per cubic metre of moisture, the temperature of the gases would be lowered by 50 DEG  C. and the formation of slime would occur in the electro-filter, the gases are first heated to 100 DEG  C., so that the final temperature after the necessary addition of moisture would be about 50 DEG  C.

The compounds in which R11 is an acyl group may also be prepared by acylating the corresponding compounds in which R11 is a hydrogen atom.  Thiosemicarbazones of the Formula II are prepared by reacting a thiosemicarbazide of the formula <FORM:1058694/C2/3> with a substituted acrolein of the formula <FORM:1058694/C2/4>

Abstract: 340,128. Horns for sound reproducers. DOUW, J. C., HEIN, J. W. V., HENNY, C. H., and HENNY, M. A. (trading as SYNDICATE J. C. DOUW'S PATENTS), 68. Frankenstraat, The Hague. Dec. 17, 1929, No. 38657. Convention date, Feb. 2. [Class 13.] A sound-amplifying horn, for example for gramophones or loud-speakers, consists of a relatively thin sheet of wood the grain of which is arranged to run in a direction transverse to the main axis of the horn, and which is held under tension by a flexible material applied to its outer surface. A combination of maple wood and the woven material known as " Lancaster " is stated to be particularly suitable. In preparing the horn, the wood and the covering material are united in the flat, and the composite sheet is then bent to the desired shape. The horn may be coated on the inside and outside with lacquer or varnish, which may be such as to cause the flexible material to shrink slightly. A plate with an opening of the necessary size may be glued around the wider end of the horn, to stiffen the structure.

The exhaust chest 19 is open at the top and registers with a flue 23. In a second embodiment refuse is fed continuously into the furnace by a piston reciprocating in a tubular charging duct beneath an open-topped hopper. A gas extraction duct leading to the atmosphere by way of a scrubber, separator or heat exchanger may replace the exhaust chest and flue arrangement. The lining of the furnaces may be acidic or basic depending on the type of refuse. Iron compounds may be added to the molten bath to reduce the fusion temperature of ceramic components in the refuse.

Abstract: 1,166,599. Cathode ray tubes. NIPPON ELECTRIC CO. Ltd. 16 Aug., 1968 [19 Aug., 1967], No. 39339/68. Heading H1D. The luminescent screen of a numerical display tube comprises a base-plate formed with a number of grooves corresponding to segments of the numbers to be displayed, each groove containing luminescent material. Since the edges of the luminescent material are clearly defined by the edges of the grooves, the usual masking electrode is unnecessary. The baseplate may be of glass or ceramic in which the grooves are formed by etching, after which the grooves are coated with a conductive coating on which the fluorescent material is deposited by sedimentation. In an alternative the base-plate may be of metal with the luminescent material deposited in grooves formed in the metal.

Abstract: 918,166. Tube couplings. PARKERHANNIFIN CORPORATION. Nov. 8, 1961, No. 40061/61. Class 99(1). In a coupling for the flared end of a tube T of work-hardening metal, including a coupling member 1 of work-hardening metal formed with a frusto-conical seat 3 having a taper complementary to that of the flared end of the tube, the seat has secured thereto a thin film 10 of a resilient resin having properties like those of tetrafluoroethylene resin and a thickness of from about 0.0003 to 0.0005 inch whereby irregularities on the seat and the flared end of the tube can be filled by the resin without extrusion of the resin from between the surfaces. As shown, the angle of taper of the seat is from about 30 to about 45 degrees, and the flared end of the tube is forced on to the seat by a nut 2 and through the intermediary of a sleeve 6 provided with a head 5 engaged by a flange 4 of the nut; the exterior surface of the head is tapered, about 1 degree, to allow resilient expansion of the sleeve without causing binding between the head and nut as the latter is tightened up.

Abstract: 989,124. Moulding reinforced articles. PLAST ANSTALT. Nov. 9, 1961 [Nov. 15, 1960], No. 40217/61. Heading B5A. In a method of moulding, a hardenable synthetic resin is introduced at atmospheric pressure into a mould containing reinforcements, allowed to partially harden, and a further amount of resin introduced at superatmospheric pressure to compensate for any shrinkage. The reinforcements are secured against further movement by the initial partial hardening of the resin. In the embodiment shown, a covered mould 3, 4, 5 containing reinforcement 6 is carried by a spring base 2, mounted and vertically movable member 1. The member 1 is raised to contact member 7 to form an airtight chamber, a hole in cover 5 co-operating with the feed pipe 11, 27 of a resin reservoir 12. The chamber is then evacuated through valve 10 and resin under atmospheric pressure admitted to the mould through valve 13 and allowed to partially harden. The valve 15 is then operated to put space 25 under superatmospheric pressure thus forcing more resin into the mould, the valve 15 being subsequently closed. After complete hardening of the resin, air under atmospheric pressure is re-admitted to the chamber through valve 19, the member 1 lowered and the finished article removed.
