Title: Methods of duplicating from sheet form printing masters onto moistened copy sheets
IPC: B41M5/025
Filed: 1965-12-10
Abstract: 1,101,159. Printing process. G. RITZERFELD. 10 Dec., 1965 [4 Jan., 1964], No. 52459/65. Heading B6C. A method of duplicating on to moistened copy sheets by means of sheet-form printing masters prepared by means of coated transfer sheets wherein duplicating is effected by chemical reaction between a plurality of substances which, individually have no colouring effect or only a weak colouring effect, and together form a dyestuff, comprises incorporating a first chemically reactive dyestuff component in the coating of the transfer sheet serving for the production of the printing master, whilst a solution of a second chemically reactive dyestuff component is used for directly moistening the image areas of the printing master already carrying the first reactive component, said moistening not resulting in the production of a colour reaction capable of reproduction by duplicating, whilst a third chemically reactive dyestuff component is used in solution for moistening the copysheet to be printed, either before or after the printing operation. That substance which requires to be present in the reaction in the smallest stoichiometric proportion is preferably used in the transfer sheet coating and may be an aromatic diamine or diamine derivative, e.g. m-phenylenediamine hydrochloride. The image areas of the printing master may be moistened with an aqueous or alcoholic solution of N,N- dialkyl (e.g. dimethyl or diethyl)-p-phenylenediamine hydrochloride. The copy-sheet may be moistened with an alcoholic solution of copper-II-chloride or of a quinene (e.g. benzoquinene). Instead of, or in addition to these substances, iodine may be employed in the moistening liquid.

Title: Antenna
IPC: H01Q7/00
Filed: 1972-11-15
Abstract: 1387679 Aerials D A R WALLACE 2 Oct 1973 [15 Nov 1972] 52725/72 Heading H4A An aerial comprises a base member such as a circular aluminium sheet 1 which is sufficiently flexible to be able at least approximately to adopt the contour of an underlying surface, a flexible dielectric material substrate 4, and support means which maintains a substantially uniform spacing between the substrate and the base when the latter is fitted to said underlying surface. The aerial also comprises a loop of electrically conductive material on the substrate, and a dual conductor connecting lead, one conductor of which is electrically connected to said loop. As described, the base member 1 has holes 2 around its periphery for securing it to the roof of a vehicle and for holding a radome 3 in place. The substrate 4 is made of fibreglass and bears two rings 5, 6 of conductive material connected respectively to the centre conductors of coaxial cables 7, 8, the outer conductors of which are connected to the base member 1. The cable connections are made close to pillars 9, 10 which provide electrical connection between the rings 5, 6 and the base member 1, and which rigidly support the substrate 4. Three other support pillars 11 are provided which are made of dielectric material and which allow for limited relative movement of the substrate, by means of elongated or oversize holes 13 for fixing screws 12. The rings 5, 6 are capacitively connected to the base member 1 at a point opposite the pillars 9, 10. As shown in Fig. 2c, one conductor of a short length of twin core flex 14 is connected to a ring, and the other conductor is connected to a variable capacitor 15 mounted on the base member 1 and having adjustment means 15<SP>1</SP>. The rings 5, 6 may be formed by printed circuit techniques and are used for different frequency ranges, according to their diameters. They may either be continuous, as shown, or they may have narrow gaps in the vicinity of the pillars 9, 8. The two coaxial cables 7, 8 may combine into a single cable (17), Fig. 3 (not shown), the length of the cable 7 being a multiple of a quarter-wavelength for the resonant frequency of the ring 6, and the length of the cable 8 being a multiple of a quarter wavelength for the resonant frequency of the ring 5. In another embodiment, which is suitable for a vehicle having a non-conducting roof, two substrates of similar design and construction, with one or more conductive loops thereupon, are supported in spaced-apart relationship from a common base member. In this case, the base member may also be of non- conductive material. Instead of the direct connection of the centre conductor of a feed cable to a ring, a capaoitive coupling may be employed in which the capacitor comprises an arcuate strip on the other side of the substrate, under a ring. The length of said strip corresponds to a quarter-wavelength at the resonant frequency of the ring.

Abstract: 1,204,026. Boring earth &c. BECKER DRILLS Ltd. 13 Nov., 1968 [21 Nov., 1967], No. 53823/68. Heading E1F. [Also in Division F2] A length of double walled pipe for a reverse circulation drill string (not shown) is joined to an adjacent length by threaded pin and bar ends 12, 13 on the outer pipes 11, 11' and a separate connector tube 22 for the inner pipes 16, 16', the inner pipes terminating short of the ends of the outer pipes and also short of the inner ends of the threading so as to receive enlarged socket ends 23 of the connector tube at positions where these ends can be accommodated without restricting flow in the annular flow passage 17 to an extent in excess of the restriction imposed by the thickened portions of the outer tube which are required to accommodate the tapered threading used for joining the ends 12, 13 while maintaining a constant outer diameter of the assembly. Ease of assembly is ensured by making the inside diameter of the socket ends 23 of a diameter sufficiently larger than that of the inner tubes to receive the latter easily, sealing being accomplished by a sealing ring 26 fitted in a groove 25 in each socket end. Where the permissable ratio of the diameters of inner and outer pipes is such that the outside diameter of the socket ends is only a little less than the inside diameter of the thickened portions of the outer tube ends, as shown in the case of the lower end of the outer tube 11; the guiding provided for the socket end of the connector tube by the interior of such thickened portion is sufficient to ensure easy location on the end of the inner tube. However, in the case of the lower socket end shown, and where the ratio of the diameters of inner and outer pipes is such that this guiding would be insufficient (as in the embodiment of Fig. 4, not shown) webs 17, 18 joining the inner and outer tubes in coaxially spaced relation may be extended to provide inclined ramp portions, as at 20 in Fig. 1, to guide the sockets smoothly into alignment with the inner tube ends. The connector tube may in a modification (Fig. 5 not shown) be a sheet metal pressing instead of a casting, as shown.

A lifting-jack comprises a truck frame 10 having two side pieces 11 arranged to receive partially therein two support arms 12, respectively, in inoperative position and spaced by an opening 13 to receive therein in inoperative position a lifting lever arm 14. The support arms 12 are pivotally secured at their forward ends to the side pieces 11 by aligned pivot pins 28 and at their rearward ends to the lifting lever arm 14 by aligned pivot pins 27. The lifting lever arm 14 is powered into elevated position through the support arms 12 by means of two telescopic hydraulic or air pressure rams 30 each pivoted at one end to one of the side pieces 11 by a pin 32 and to one of the support arms 12 at the other end by a wrist pin 35. The angular movement of the lifting lever arm 14 about the axes of the pins 27 is controlled in such a manner as to cause a lifting head 70 on the forward load bearing end of the lifting lever arm 14 to follow a substantially vertical straight path by horizontally guiding the rear end of the lifting lever arm 14 by guiding means 49 provided in conjunction with a housing 15. The guiding means 49 comprise rollers 65 riding on rails 57 and rollers (101), Fig. 15 (not shown), riding between upper and lower guide strips (51) and (54) respectively. The lifting head 70 is maintained horizontal by a parallel motion mechanism comprising a stabilizing arm 90. When the lifting lever arm 14 has reached its lifting limit the load can be transferred to a screw jack 25 pivoted at 85 to the lifting head 70 and, when in inoperative position, nested in the lifting lever arm 14. The truck frame 10 is supported on a pair of front wheels 16 and a pair of rear wheels 17. A pair of spring-loaded castor wheels 20 raise the forward end of the jack when it is not loaded. A pair of stabilizing brakes 22 lock the jack in position against movement along the ground while under load. A jack pad 75 is adapted to fit a jack point (not shown) secured to part of the load, e.g. the underside of the tail or wing of an aircraft to be lifted. The jack pad 75 operates for that purpose, not only during the full lift of the lifting lever arm 14 but also during the additional full operation of the screw jack 25 without changeover in the jack point of support, the jack 25 being released from its nested position, where it is retained by a chain (118), Fig. 5 (not shown), when the lever arm 14 has been fully raised.
