Title: Improvements in protective papers for use in agriculture and in horticulture
IPC: C09K17/52
Filed: 1931-01-02
Abstract: A protective paper for agricultural or horticultural use, capable of rotting when buried in the soil, contains added fertilizer, or fertilizer and insecticide, and also one or more added animal or vegetable oils or waxes so that the paper is capable of long exposure on wet soil or to rain without becoming defibred or pulped.  The paper may be impregnated with oil such as fish oil or coated with wax such as stearin and it may be coated or impregnated with fertilizer or fertilizer and insecticide.  A compound sheet may be formed having the fertilizer or fertilizer and insecticide placed between adjacent papers.  In such compound sheets, two or more papers may have waxed surfaces on the outside, such surfaces being incised or perforated to allow water to penetrate to the fertilizer and carry it into the soil.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form wherein paper semi-parchmentized with sulphuric acid or zinc chloride is used.  This subject-matter does not appear in the Specification as accepted.

Jan. 8,1946, Nos. 700 and 701. Convention dates, Dec. 7, 1944, and Aug. 7, 1945. [Class 38 (iv)] In a device for distributing a common load between a number of generator units on a basis of economy, the parameters of the regulators associated with the generator units, as described in Specification 617,234, are adjusted and an e.m.f. is introduced in each regulator in accordance with the load fluctuations. As shown, the servo-motor 3 causes the contact arm 1 to be positioned longitudinally corresponding to the instantaneous total power. Contact is made with one of the segments 4, 41, 4<11>, 4<111>, 4<1111>, to cause energization of the associated relay 5a, 5b &c. from source 9. Corresponding with each relay is a set of resistors R, R<1>, R<11> and an e.m.f. source S<0>, associated with each generator or power station regulator, which control the output of that regulator, i.e. A, B or C in correspondence with whichever of the segments 4, 4<1> &c. is in contact with arm 1. The law followed by the power output of each generator unit is of the form y = ax + b, where x represents the total power supplied by the system. In modifications, the generators are conditioned to meet changed load conditions before their commencement and they may be adjusted to yield a constant output over a given extent of total load change.

Fixed contacts i - - i<5> comprise copper strips with doubled inclined ends as shown, the strips being adjusted by screws m and carried by terminal brackets h. A helical compression spring forces the core c up against a stop and into a position in which the fixed and moving contacts are all touching with the spring pressure of the contacts acting against the compression spring. The moving contacts f - - f<2> are all at the same height and the contacts i - - i<5> are at successively greater heights in the order i<5>, i, i<3>, i<2>, i<4>, i<1> so that, as the current in the coil increases, the contacts are broken in this order and the pressure on opposite, sides of the core is equalized throughout. Resistances R - - R', Fig. 3. preferably of positive temperature coefficient are connected between the fixed contacts i in the circuit from the cut-in switch q to the lamps r and are successively thrown into circuit as the voltage increases, the coil b being connected in shunt as shown with or without some series turns.

[Class 100 (ii).] In a paper-folding machine employing an oscillating blade 5, the operation of the blade is wholly independent of the main driving mechanism and is controlled electrically by the travelling sheet through a clutch mechanism. In the arrangement shown diagrammatically in Fig. 3, the blade 5 is carried by a double-armed lever 5a, 5b, controlled by a balancing spring 19, and is depressed by a lever 18 connected near to the centre of the arm 5a and oscillated by a balanced crank 17 on a shaft 9. A clutch coupling 10 is provided between the shaft 9 and a high-speed shaft driven by an electric motor, the knife 5 being held in its raised position normally by the engagement of a pin 25 on the part of the coupling 10 attached to the shaft 9 with a stop 12. As a sheet reaches the folding position beneath the knife 5, it engages a stop 15 and lifts a feeler 16, the latter operating an electric relay 21, 22 which causes an electromagnet 13 to be energized and thus, through an armature 23, to lift the stop 12. When the pin 25 is freed, the coupling 10 is thrown into operation and the knife 5 folds the sheet. The stop 12 returns to its initial position and engages the pin 25 so as to release the coupling 10 after one revolution. Further, the crank 17 may be connected directly to the centre of the arm 5a or to the end of the arm 5b. The connection of the crank 17 to the lever 18 or arm 5a is adjustable to vary the throw.
