Abstract: 1,026,582. Haymaking machines. C. VAN DER LELY N.V. April 24, 1964 [May 13, 1963], No. 17188/64. Heading A1F. In a rake-wheel type of haymaking machine each rake-wheel is rotatable about a fixed axis and is also adjustable relative to two mutually-perpendicular axes which intersect the fixed axis. The mechanismframe 1 is L-shaped in plan and is mounted on three casters 2 which are height-adjustable, the rotation-plane of the reamost being also lockable. A shaft 5 is rotatably mounted across the extremities of the frame and is driven by a belt-drive 7, 8, 9 from a shaft 31, connected to the power take-off of a tractor 33 by a jointed shaft 10. The hub 14 of each rake-wheel 6 includes a double gimbol-mounting 17, 18, 19, 20 connecting it to the shaft 5 and is suspended freely in a ring-bearing on the lower end of a T-shaped lever 15, the upper limbs of which are mounted in a pair of parallel bars 22 connected together for both relative movement in opposite directions and bodily movement in unison across the frame. Bodily movement tilts the planes of the T-shaped levers to the vertical, and, with them, the rake-wheels; relative movement of the rods rotates the levers 15 about their vertical axes so that the rake-wheels alter their inclination to the line of draft, while remaining vertical. In a modification (Fig. 4. not shown) the gimbol-bearings 18, 20 are spring-mounted to enable the rakewheel more readily to absorb shocks.

Patent GB-564583-A (GB)
Title: Improvements in and relating to the parchmentisation and vulcanisation of cellulose fibres
IPC: D21H17/65
Filed: 1942-12-10
Abstract: Cellulosic materials are pre-treated with sulphuric acid of less than parchmentizing strength and are then treated with sulphuric acid of parchmentizing strength without substantial solution of the cellulose.  Treatment with the stronger acid may be continued until a product suitable for moulding is obtained. After the parchmentizing treatment, the acid may be removed by washing or by neutralization. The treated material may be pressed and dried so as to form a mass which is hard and light, is a good electrical insulator, and is capable of being moulded under heat and pressure.  Cellulose fibres in the form of sheets of paper may be subjected to the acid treatment and then laminated and pressed together.  Fibres, yarns, films, scoured sawdust, wood pulp, macerated paper, or knitted or woven cellulosic fabrics may be treated.  In an example, several sheets of bleached or unbleached kraft paper are individually dipped in sulphuric acid of 90 DEG  Tw. for a few minutes.  Excess of liquid is then squeezed out and the sheets are dipped in sulphuric acid of 160 DEG  Tw. for about 1 minute at room temperature.  The sheets are washed and then laminated, pressed, and dried to form a hard mass capable of being moulded.  Formaldehyde may be added to the strong sulphuric acid.

Abstract: 284,929. Khan, H. R. July 4, 1927. Aerials.-A radiating system comprises elevated conductors e', e<2> lying in the same straight line and fed with high-frequency currents at the points d<1>, d<2> the circuit being completed across an intervening space between the two free ends f<1>, f<2> which are preferably fitted with a bundle of points as shown. The feeding-cables are enclosed in conduits of sheet-iron, wire-netting, or other suitable screening means, spaced a sufficient distance away from the wires to miminize inductive action on the supply current. The feeding cables are of equal length and gauge, and the radiating conductors are so loaded with inductance and capacity that the current at any instant in the system is stated to be in the same direction and to have the same frequency, intensity, and phase. Maximum radiation occurs in a plane at right angles to the current flow. The number of conductors may be increased as shown in Fig. 4, or they may be mounted in a vertical plane as shown in Fig. 5. To increase the directional effect, auxiliary reflecting antennae may be associated with the conductors e<1>, e<2>, Fig. 5, either in a straight line or in the form of an arc. Iron sheets or wire netting may also be arranged to cut off back radiation and to increase the concentration of energy in any desired direction. One or more of the aerial conductors, as in Fig. 4 may be switched out of operation to reduce consumption for short-range working. The conductors may be mounted at any angle to the horizon, provided that each working pair is arranged in the same straight line and that sharp angles are also as far as possible avoided in the feeding-cables. To prevent leakage losses the masts, stays, and guys are coated with insulating compound. The earth in the vicinity of the aerial system is preferably cleared of vegetation and covered with a thin layer of coal tar or other insulating material. The radiating system is preferably mounted on a rotatable framework, supported by rails, and capable of being set to any desired orientation. The invention is based upon a particular theory of wave propagation which is set out in detail in the Specification.
