Filed: 1956-02-03
Abstract: 792,586. Optical-projection apparatus. REFLECTONE CORPORATION. Feb. 3, 1956, No. 3542/56. Class 97(1) Apparatus for showing a composite projected picture of a plurality of relief objects, each having a light reflecting portion, comprises lenses associated with the respective objects to produce images of the light reflecting portions as a composite picture, the objects being mounted for simultaneous rotation about axes perpendicular' to their projection axes. In the form shown three separate objects 11, 12, 13, for example boat models, have different parts, intended to. be projected, rendered light reflecting, the remainder blackened, and are mounted on axes 18, 17, 23 at the centres of the light reflecting portions of which images are projected by lenses 14, 15, 16. The axes 18, 23 are carried on gear wheels 21, 24 meshing with fixed racks 20, 25 and also engaged by racks 22, 26 secured respectively to racks 30, 31 meshing with a gear wheel 27 on which the pivot 17 is carried. The wheel 27 is twice the size of the wheels 21, 24. This system produces simultaneous rotation of all the objects with opposite linear displacements of the 11, 13 as needed to maintain proper juxtaposition of their images with that of the object 12. In another form the parts of the models not to be projected are omitted, part models only being used. These models are pivoted about fixed axes identically related to the whole models of which they are in effect, parts and are coupled for simultaneous rotation. This causes an axial displacement of some of the part models during the rotation and this is compensated by adjustment of the objectives or parts of the objective systems this adjustment being coupled to the rotation of the models.

Abstract: A corrosion-protective coating comprises in adherent contact (i) an electrolytically deposited Nicontaining P-free lower layer, (ii) an intermediate layer of Ni-P alloy which may be deposited electrolytically or by electroless deposition, and (iii) an electrolytically deposited Nicontaining P-free upper layer, the intermediate layer being anodic relative to the upper and lower layers, i.e. more easily corroded.  The Ni-Palloy may include 0.4 to 10% by weight of P.  Each of the layers may contain Co, e.g. the lower, intermediate and upper layers respectively containing 0-25%, 0-25% and 0-50% by weight.  The Ni-P layer may include minor amounts of S, Se, Te and As.  The lower and upper layers may contain respectively less than 0.15% and 0-0.3% of S. The upper Ni layer may be electro-plated with Cr.  Specified substrates are of Fe, steel, Cu, Zn, Al, Mg and alloys thereof. The substrate may have a Cu strike thereon.  The Ni may be plated from a solution containing at least one of the following salts: nickel sulphate, chloride, fluoborate and sulphanate.  Where Ni-Co alloy is to be plated, the Co may be included in the solution as cobalt chloride, bromide or sulphate. Buffers such as boric acid, acetic acid, borax, formic acid or fluoborates and wetting agents, e.g. of the sulphate type, may be used.  The lower and upper layers of Ni may be deposited from baths containing one or more brighteners of a first class (a sulpho-oxygen carrier).  These compounds may comprise an aryl ring, a substituted aryl ring or an unsaturated aliphatic chain with a sulphur containing radical in the form of sulphonic acids, sulphonates, sulphonamides, sulphimides, sulphinic acid or sulphones.  These baths may in addition contain brighteners of a second class including organic compounds where the brightening action depends on the carbonyl, ethylenic or acetylenic radicals, azo or azine type nuclei or on the cyano or thioureide radicals. The Ni-P alloy plating baths may contain the P as <FORM:1081793/C6-C7/1> where n is O or 1, m is O or 1 and R represents H, an alkali metal, Ni, Co, or an alkyl, aralkyl, aryl or alkaryl radical. Specified P compounds include phosphorous acid, organic phosphonic, hypophosphorous, organic phosphinic, organic phosphonous and organic phosphinous acids and their derivatives. For electroless plating with Ni-P, hypophosphite baths are mentioned.  Many specific examples are given of solutions and plating conditions.

Abstract: 607,514. Operating clutches. NUFFIELD MECHANIZATIONS, Ltd., MERRITT, H. E., CULPIN, C., and GREGORY, G. Feb. 7, 1946, Nos. 3821 and 16269. [Class 80 (ii)] [Also in Group XXXI] Excessive pull on the draw-bar 12 of an agricultural tractor acts through a cam 16 to rock a trip-lever 1, on a fixed pivot 2, in opposition to a spring 11, to depress the tractor clutch-pedal 8 through a pull-rod 3 and preloaded spring 4, and the clutch is then latched in the disengaged position, as by a rollerfollower 21 on the trip-lever 1 falling into a recess 22 in the cam 16, until the cam is manually released by a re-set lever 17, or unless a supplementary hand-lever 23, fast on a shaft 24 which freely carries the clutch-pedal 8, is moved forwardly (to the left of Fig. 1) to reengage the clutch temporarily by raising the clutch-pedal 8 through a shoulder 27 on a fast lever 25, in opposition to the spring 4, which re-asserts itself and again depresses the clutchpedal 8 as soon as the hand-lever 23 is released. In normal operation the latch mechanism can also be tripped by rearward movement of the hand-lever 23 which acts, through the lever 25, on the pull-rod 3 in the same direction as the draw-bar 12, and with the clutch latched disengaged, the hand-lever can be used for spring- opposed clutch re-engagements as before, for manoeuvring the tractor. Fig. 2 (not shown) uses separate cam and latch levers an adjustable compression-spring in place of the tension-spring 11. Fig. 3 (not shown) uses a combined latch and cam lever, as in Fig. 1, which acts on a draftsensitive adjustable compression spring through a pull-rod connected also to the manual re-set lever, which applies a release thrust to the latch through a light-spring which yields without effect if the latch has not first been relieved of load by depression of the clutchpedal or operation of the hand-lever.
