Abstract: 1407220 Forming furrows and trenches BAGGERMAATSCHAPPIJ BOS & KALIS NV 18 Dec 1972 [21 Dec 1971] 58316/72 Heading A1B An implement for tilling or excavating comprises a frame 5 mounted on a tractor and carrying an inclined upper surface 4 which is moved forwards, upwards, backwards and downwards relative to the frame as the implement is pulled through the soil, to reduce the drag on the implement. In Fig. 1 the surface 4 is cycled by two eccentrics 8 mounted in fly wheels driven from a pinion 11 through a chain 10. The upper eccentric may be omitted. In Fig. 12 (not shown) the drive is transmitted through a connecting rod and two links. On the upward stroke the resistance to forward motion of the surface 4 holds the implement back and the forward motion of the tractor is accommodated by a hydraulic cylinder connected between the implement and the tractor. The implement may be used for laying a drainpipe in the trench formed or for tilling. The excavated soil is shifted over the surface 4 into the trench behind the implement. The surface 4 may be formed as a grid to mix the soil before it is returned to the ground. In Fig. 8 (not shown) the cross-section of the surface 4 corresponds to that of a trench to be dug and the excavated soil is shifted laterally by a conveyor at the upper end of the surface 4. In Fig. 9 (not shown) a strip of soil is moved up the surface 4 and cut into slices by a rotating knife. The slices are inverted and returned to the ground. In Figs. 10 and 11 (not shown) the implement is used underwater at the end of the suction pipe of a suction or cutter dredger. The implement may also be used as the shovel or pushing element of a bulldozer.

Filed: 1973-12-19
Abstract: 1455259 Dry shavers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Dec 1973 [22 Dec 1972] 58760/73 Heading B4B An electric dry-shaver comprises an electric motor 2 having a stator 3 and armature 4, and a long-hair clipper including a reciprocable cutter 28 which may be engaged or disengaged from driving connection with the armature of the motor by means of a manually operable actuating member 29, the actuating member having a pivot-forming part 32 adapted to engage with a further pivot-forming part 31 provided on a lever 30 when the cutter is in driving connection with the armature. As shown in Fig. 1, the armature is mounted on a pivot pin 13 secured to frame plates 9, 10 which are secured to the stator 5. The lever 30 is pivotally connected at one end 43 to the armature by a pin 4 and, at its other end, engages with lugs 39 formed on the cutter. In the position of the actuating member 29 shown in Fig. 1, the pivot-forming part or pin 31 is located between projections 32 on the actuating member thereby causing the cutter to be reciprocated by the lever upon oscillation of the armature; the actuating member is retained in this position by a spring 34. Upon depressing the actuating member, the projections are moved out of engagement with the pivot pin 31 thereby allowing the lever to pivot about its end located between the lugs 39 on the cutter; the cutter is prevented from movement by friction. In the modification shown in Fig. 7, the actuating member is in the form of a rotatable knob 48 having an elongated slot 50. In one position of the knob, the larger sides of the slot engage pin 49 on the lever 30 to cause reciprocation of the cutter; in a second position of the knob, the pin is free to move within the slot and thus prevent actuation of the cutter. The actuating member may be of nylon. In a further modification the oscillating type motor may be replaced by a rotary motor, suitable mechanism being provided for converting the rotary motion of the motor shaft into reciprocating movement of the end 43 of the lever.

Typical support materials which may be foamed, comprise polystyrene, polyesters, polyolefines, polyamides, polycarbonates, polyvinyl chloride, or cellulose acetate resins or polyacetals. In admixture therewith, titanium dioxide, barium sulphate, calcium sulphate, barium carbonate, lithopon, alumina white, calcium carbonate, silica white and similar white pigments may be present together with coloured pigments. In example 6 the support is a cellulose triacetate coated silver band. The roughened surface is in the form of fine open pores and/or projections and may be formed by mechanical or chemical means. The surface may additionally be pre-treated with a Corona discharge, or by ultra-violet radiation and/or ozone oxidation activation or by coating with a surface active agent. The support is preferably in the form of a film. The hydrophilic resin coating is preferably applied by dipping and this resin may comprise a natural or synthetic polymer having some hydrophilic groups such as -OH, -COOH, -COOCO-, -SO 3 M (where M is a hydrogen atom or an alkali metal), -NH 2 , or -CONR 1 R 2  (where each of R 1  and R 2  is a hydrogen atom or alkyl group). Examples of SL ch polymers are gelatin, cafein, cellulose aceta e maleate, vinyl-maleic anhydride copolymer, polyvinyl pyrrolidone, polyacrylate, and polya crylic acid. The support may then be coated with a photographic emulsion such as silver chlorobromide and gelatin emulsion. Where the surface treatment is applied to foams, t is rendered receptive to aqueous inks, paints and adhesives facilitating production of, for example, ornaments, building materials and toys.
