Abstract: 1527449 Making ferrous martensitic sintered bodies FORD MOTOR CO Ltd 14 June 1977 [26 Oct 1976] 24766/77 Heading C7D A ferrous based compact with a martensitic structure is made by impacting the ferrous particles at ambient temperature e.g. in a ball mill, with Fe or Cu balls at least 50 times larger than the particles to cold work the particles and cool them with Cu or Fe. The coated particles are then compacted and sintered e.g. at 2000-2100F. The particles used are preferably machine turnings which are heat treated to form at least 80% martensitic structure and then milled to chips of -30 mesh. The Fe or Cu balls used in impacting are at least 0À1 inch diameter.

The supply of gas to the burners 8 may be controlled by thermostats 23, 26 arranged in the generatorabsorber and the evaporator respectively of the machine. A device 25 cuts off the supply of gas to the burners 8 if the pilot jet 24 is extinguished. Cold water is admitted to the tank and the sink through pipes 27, 28 respectively, while hot water is drawn from the tank to the sink through the pipe 30. In a modification, the generator-absorber is placed in the tank, while in another arrangement, the condenser of the machine and the condenser of an evaporator-condenser cooling system for the generator-absorber are disposed in the tank.

Title: Improvements in or relating to the production of water-resistant basic or neutral calcium sulphite in the form of lumps
IPC: C01F11/48
Filed: 1934-08-29
Abstract: Water-resistant basic or neutral calcium sulphite in the form of lumps is produced by treating with sulphur dioxide at normal temperature calcium hydroxide in the form of lumps or in the form of bodies that have been shaped with the aid of water, and heating the resultant product between 100 and 400 DEG  C., preferably in the presence of sulphur dioxide, until by dehydration the necessary stability in water has been obtained.  Cooling of the product may take place also in the presence of sulphur dioxide.  When using shaped bodies of calcium hydroxide, the shaping preferably takes place in the presence of a plasticizer such as sodium carbonate or of substances adapted to increase the porosity of the bodies, such as wood charcoal, active carbon, silica gel, asbestos, pumice stone, metallic aluminium, magnesium, or calcium, or ammonium salts.  The products may be used for purifying liquids, or for removing oxidizing or acid gases, such as chlorine, ozone, carbon dioxide, or sulphur dioxide, from gas mixtures.  The Specification as open to inspection under Sect. 91, comprises also a modification for the production of bodies containing neutral sulphite and calcium carbonate, wherein the shaped bodies consist of calcium hydroxide or carbonate or mixtures thereof, and after the sulphur dioxide treatment in the cold, a treatment with carbon dioxide is interposed, if necessary before the heat treatment.  This subject-matter does not appear in the Specification as accepted.

Title: An improved springing arrangement for bicycles, motor cycles, and power-driven vehicles of all kinds

Abstract: 347,992. Cycle &c. spring frames. WAGNER, W., 31, Offenbacherstrasse, Sprendlingen, Germany. Aug. 26, 1930, No. 25434. Convention date, Aug. 27, 1929. [Class 136 (iii).] In a spring suspension for cycle saddles, handlebars, motor vehicle axles, &c. a resilient member, such as a helical spring, is interposed between a rack and a pinion meshing therewith, or between parts rigidly connected with these members, and one of the relatively-sprung parts is connected either to the rack or to the pinion, and the other of the relatively-sprung parts to a second rack guided parallel to the first rack, the second rack meshing with the pinion or with another pinion rotating positively therewith. The suspension is shown applied to a cycle saddle, and comprises pairs of pinions 1, 2, rotatably mounted on opposite sides of a U-shaped frame 5 and in mesh with racks 6, 7, rigid with a tubular member 24 adapted to be secured to the seat pillar &c. of the cycle frame, the pinions 1, 2 also meshing with racks 8, 9, which are connected rigidly together by a U-shaped frame 10 and are displaceable vertically parallel to the racks 6, 7. The movement is controlled by a helical spring 12, which is interposed between the frame 10 and a bracket 11 on the frame 5 and is mounted on a guide rod 13 slidable through the bracket 11. Additional springs 36, 37 may also be arranged between the frames 5, 10. The frame 5 is rigidly connected by struts 14, 15, 16 to a horizontal member 17, to which the saddle is secured. Parts 20, 21 are supported on the cycle frame, and are connected together by inclined struts 22, 23 and a tubular member 19, to which the member 24 is fixed. The pinions are rigid with grooved rollers engaging guide bars rigid with the racks 8, 9, the rear edges of the guide bars being engaged by further grooved rollers 31, 32. The opposed racks 6, 8 and 7, 9 respectively, instead of being engaged by the same pinions 1, 2, may be engaged by separate pinions of different sizes keyed on the same shafts, so that the displacement of the racks 8, 9 is different from that of the racks 6, 7. Further springing may be provided by connecting the frame 5 by links 39, 42 to one arm of a bell-crank lever, which is pivoted on the front of the cycle &c. frame and has its other arm connected to a helical spring.

Title: Improvements in or relating to aerials
Inventor: RAMSAY JOHN FORREST
IPC: H01Q15/22
Filed: 1956-08-21
Abstract: 807,828. Radio reflectors. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 7, 1957 [Aug. 21, 1956], No. 25513/56. Class 40 (7). The invention relates to an aerial structure which functions in substantially the same way as the structure described in Specification 776,258 and comprises an arrangement stated to be easier to construct. According to the invention the surface of revolution of more than 180 degrees of arc and provided with reflector elements each substantially at right angles to the diametrically opposed element if any previously disclosed is subdivided into sections bounded by planes perpendicular to the axis of revolution. The elements in each section are each arranged, as before, to be at right angles to the element diametrically opposite, which element is in the same section. The surface of revolution may be parabolic, elliptical or spherical and Fig. 1 shows a parabolic surface extending over a full 360 degrees of arc about its axis of revolution and divided into six sections referenced 3 to 8 inclusive. As shown more particularly with reference to section 6 each reflector element is a wire shaped to follow the direct projection, on the surface of revolution of the section, of a line at 45 degrees to the tangent to the mid-circular arc of that section, the line passing through the point of contact of the tangent and lying in a plane including said tangent and perpendicular to the radius of said arc at the point of tangency. In the Figure the mid-circular arc of the section 6 is indicated at 10. Reflector elements shaped thus depart from the correct theoretical angular alignment by an amount proportional to the distance from the mid-section circular arc. However, if the number, of sections is adequate a structure of considerable axial height can be made in which no large errors occur. If a divergent radio energy beam from an internally arranged horn 9 is directed on to the internal surface of the structure with a polarization such that reflector occurs it will be reflected across the structure and pass unimpeded through the opposite side as a substantially parallel beam. The horn 9 may be rotated about the axis of the structure to give an azimuthal scan or a plurality of angularly separated horns may be used to give a like plurality of independently directed radio beams. The structure may conveniently be made by preparing a woven material of glass fibres incorporating parallel reflector wires and placing strips of this material having the wires at 45 degrees to the length of the strip and a width appropriate to the required section height round a former and then impregnating the structure in known manner to achieve the necessary mechanical rigidity. The structure may also be built up of rigid wires or the reflector elements may be resonant dipoles or slots.
