Title: Improvements in or relating to apparatus for the treatment of turf
Inventor: MARGREAVES DEREK BURTT
IPC: A01B35/24
Filed: 1958-03-04
Abstract: 903,343. Agricultural implements; treatment of turf. HARGREAVES & CO. Ltd., W. March 3, 1959 [March 4, 1958], No. 6859/58. Classes 6(1) and 6(2). An implement for treating turf comprises a frame having slitter discs mounted at one end and an assembly of spring tines at the other, and provided with at least one handle. As shown in Fig. 2, the implement comprises a frame 10 provided at one end with rods 11 and 12 yieldingly supporting tines 13 and provided at the other end with a fixed axle 14 on which slitter discs 15 are freely mounted. The implement also comprises an X-shaped handle 18 pivoted at its lower extremities to the frame 10, and further connected to the frame by springs 19, so that pressure exerted on the handle is transmitted to the tines via the springs. In order to use the implement as a rake only, the axle 14 may be extended outside the frame to mount detachable wheels, thereby raising the slitter discs out of contact with the ground, or by turning the implement over, a slitting operation only may be effected. If the detachable wheels are mounted on the axle 14 with the implement in this latter position, transportation of the implement is facilitated. On a modification, the angle of the handle relative to the frame is adjusted by means of projections on the lower extremities of the handle engaging holes in the frame or abutting against the lower edges of the frame, and brackets are provided on the frame for the reception of a brick to add weight to the implement. Mention is made in the Specification of the possibility of mounting wheels permanently on the frame in such a manner as to be adjustable into and out of their operative position, and of converting the slitter-disc assembly into a roller by covering the assembly with two semi-cylindrical members.

Title: Improvements in or relating to Machines and Processes for Folding Canvas-strip for Driving-belts and other purposes.
Inventor: WARWICK GEORGE
IPC: F16G5/08
Filed: 1916-05-16
Abstract: 106,320. Warwick, G., and Crouch, A. P. May 16, 1916. Folding edges of sheet material.-In folding canvas strip for engine packing or to form the cores of driving-belts for motor-cycles, the strip is drawn through dies shaped to keep the main body of the strip flat but to turn up and fold over the edge to the main body, each die being arranged to repeat the process until the whole is folded into a compact band, as shown in Fig. 13. The canvas strip C, Fig. 1, passes over a support B to dies D, Fig. 5, where the edge is folded loosely, the fold being maintained by a curved plate E<1>. The strip then passes between dies F, Fig. 6, which fold the material more tightly, the upper die having a tongue F<2> formed by a metal strip F<3>, and the fold is then pressed between rollers G, G'. The strip then passes through dies H, Fig. 9, which fold partially the part already folded by the previous dies, and between dies J, Fig. 11, which complete the fold, and thence to rollers K, K<1>. The material then passes through a succession of dies, similar to the dies H, J, and rollers until the whole is folded up, succeeding dies being narrower in proportion to the unfolded width of the material and deeper in proportion to the increased depth of the folded part of the strip. To start the machine, the material is fed by hand through the dies D, F and thence between the rollers G, G'. The roller G is mounted on spring-controlled arms G<2> capable of being raised to insert the strip, and has a reduced portion adjacent to the folded material and loosely mounted on the shaft of the roller, and the lower roller G<1> has a knurled surface. The material is similarly passed through all the other dies and pairs of rollers, and the machine is then driven by a chain through a free-wheel sprocket G<8> on the lower roller G<1>, which drives the next roller by a chain K<2>, a sprocket G<9> fast on the roller G<1>, and a free-wheel sprocket K<3>, so that, if the tension between any two pairs of rollers is insufficient, the slack can be taken up by rotating the appropriate roller and all succeeding rollers by means of a key, such as K<5>, on the lower roller of the pair just beyond the slack part. In order to maintain the tension, each pair of rollers has a greater peripheral speed than the previous pair. The edge of the strip remote from the folded part is guided by adjustable side guides L.

In the latter form the recesses may be so pronounced as to produce a star or cross cross-section. Each member has a projection on one face and a recess on the other and is bifurcated to clip on the edge of the stringer in the usual way.
Patent GB-742468-A (GB)
Title: Improvements in or relating to corrosion-inhibiting compositions
IPC: C23F11/12
Filed: 1952-03-19
Abstract: A composition for retarding the corrosion of a metal surface comprises an inert solvent and a plurality of compounds, each including a carboxylic acid group, at least one of said compounds being aromatic and at least one being present as a bivalent metal salt, the aromatic compound being present in an amount in excess of that soluble in the solvent in the absence of other ingredients, any of said compounds not present as bivalent metal salt being present as the acid itself.  Preferably the composition contains only two compounds, one an acid and one a salt, one non-aromatic and one aromatic comprising mono-and polybasic mono- and polycyclic aromatic acids which may be substituted in the nucleus by hydroxy, amino, alkyl, alkoxy or hydroxy-alkyl, the number of side chain carbon atoms not exceeding 12.  Aliphatic, alicyclic, or heterocyclic acids may be used.  Examples of the various types are given.  Complex formation occurs between the acid compounds.  For treating razor blades, a preferred composition contains benzoic acid and zinc naphthenate with a non-drying oil, grease or wax as solvent.  Solvents include mineral oils, and synthetic ester, polyether or silicone oils. The solvent may be present in the liquid or paste compositions obtained commercially, e.g. as "crude" naphthenates.  The compositions are also used in compounded lubricating oils.  The acid and metal salt are normally used in equimolar amounts, the total concentration being such as to avoid settling out from the solvent.  Using benzoic acid-zinc naphthenate, if these are first heated together, a greater amount is taken up by the solvent at room temperature.  With solvents having high solvent power for benzoic acid, e.g. isopropanol or methyl ethyl ketone, these are best saturated with benzoic acid prior to adding the combined materials.  The concentration of aromatic acid in the composition is generally .007-20 per cent.  Auxiliary agents include anti-oxidants, stabilizers, and anti-freeze while mineral spirits may be added to give desired fluidity.  Examples describe the preparation and use of compositions containing benzoic acid and "crude" zinc, calcium strontium, barium or lead naphthenate, benzoic acid, zinc naphthenate and mineral oil, anti-corrosion oil or di-(2-ethylhexyl) sebacate; zinc benzoate, naphthenic acid, and mineral oil; p-toluic acid, zinc naphthenate, and di-(2-ethylhexyl) sebacate; benzoic acid, zinc caprylate, and mineral oil; a -naphthoic acid, calcium naphthenate, and mineral oil; benzoic acid, zinc benzoate, and mineral oil; benzoic acid, lead acetate and di-(2-ethylhexyl) sebacate; zinc benzoate and "crude" zinc naphthenate; and lead benzoate and "crude" calcium naphthenate.

Title: An improved element for storage battery cells
IPC: H01M4/02
Filed: 1922-03-10
Abstract: 176,801. VarÚ, E. March 10, 1921, [Convention date]. Electrodes.-A storage battery electrode comprising a conductor surrounded by active material contained in a porous vessel is constructed so that the horizontal sectional area of the active material can be increased to allow for expansion. In one form shown in plan in Fig. 2 a corrugated elastic plate 8 is inserted between the porous vessel 1 and active material 2. In a modified construction the conductor inserted in the active material is hollow and of star shape in section as shown in Fig. 3. Expansion of the active material causes the parts 6, 7 of the conductor to move towards one another. The Specification as open to inspection under Sect. 91 (3) (a) describes other methods of allowing for the expansion of the active material. In one method elastic or plastic bodies of gutta-percha, paraffin or celluloid are placed in the porous vessel. Another method consists in making the active material in the form of hollow granules capable of collapsing under increased pressure, or the active material may contain hollow granules made by cutting up thin-walled metal tubes which form empty spaces into which the active material can expand or which can collapse under increased pressure. This subject-matter does not appear in the Specification as accepted.

Patent GB-1075193-A (GB)
Title: Improvements in or relating to a process for preparing densified particles of nitrocellulose
IPC: C08B5/06
Filed: 1965-02-22
Abstract: "Densified" nitrocellulose particles are produced by forming a slurry by agitating water-moist nitrocellulose fibres free from fibre aggregates in a mixture of a volatile hydrocarbon diluent, a volatile nitrocellulose solvent miscible in all proportions therewith and a small proportion of a water-soluble protective colloid, the mixture of diluent and solvent being capable of softening and swelling the nitrocellulose fibres but not of dissolving them and the solvent being soluble in water at ordinary atmospheric temperatures to the extent of at least 2.5% by weight, subjecting the slurry to high shear action until the softened and swollen fibres break down into smooth surfaced rounded particles, initiating the hardening of the particles by dilution of the slurry with the hydrocarbon diluent while the high shear agitation is continued, and finally removing substantially all of the nitrocellulose solvent and water by azeotropic distillation in the presence of hydrocarbon diluent (in a proportion sufficient to prevent resoftening of the particles) to complete the hardening and densification of the nitrocellulose particles. The diluent may be a volatile petroleum hydrocarbon or mixture of volatile petroleum hydrocarbons, for example heptane in a petroleum distillate boiling between 190 DEG  and 240 DEG  F. preferably between 201 DEG  and 217 DEG  F.  The nitrocellulose solvent may be methyl ethyl ketone and the nitrogen content of the nitrocellulose may be about 11% by weight or over 12.6% by weight. The initial ratio (by weight) of the diluent to the solvent in the slurry may be between 1.0 and 1.2.
