Abstract: 1,071,596. Haymaking machines. PATENT CONCERN N.V. Aug. 11, 1964 [Aug. 16, 1963], No. 32771/64. Heading A1F. A haymaking machine comprises a frame 1 and a plurality of positively-driven rake-heads 14-17 arranged in pairs, each pair being supported on two groundwheels 24 and being coupled to the frame by a supporting structure comprising sleeves 2, 3, 6, 7, 8, 9, and gearboxes 4, 5, 10-13, each supporting-structure being rotatable freely about a horizontal axis constituted by the axis of a driving shaft within the sleeve 2 or 3. The frame includes a chain-casing 60 housing a chain 58 (Fig. 2) entrained around sprockets 41, 43 and driven by a shaft 56 which can be coupled to the towing tractor (not shown). The sprockets 41, 43 drive the driving shafts within the sleeves 2, 3, which, in turn drive pairs of shafts in the sleeves 6, 7 and 8, 9. Each final gearbox, such as 10, houses a bevel gear 39 driving a bevelgear 29 on a sleeve 28 which carries the spokes 30 of the rake-head 14 the sleeve 29 being rotatable on a shaft 18 the lower end 19 of which adjustably carries the cranked axle 23 of the ground wheel 24. The machine is drawn along by a drawbar 72 securable to brackets 62 on the main frame 1, the working height of the units being adjustable by vertically adjusting the drawbar about its axis 74 of attachment by means of a screwed spindle 71. For transport, the chain-casing 60 is turned through 90 degrees so that it lies above the frame-beam 1 (Fig. 6) and the rake-head pairs are swung about the sleeve-axes 2, 3 to lie perpendicular to the beam 1 so that the machine rests upon the four ground-wheels 24. The drawbar 72 is then attached to a pair of lugs on the sleeves 8, 9. Each rake-head spoke 30 (Fig. 4) carries on its outer end a double tine 31, 31A anchored to the spoke by coils 32, 33 engaging a cross-pin 35, the coils being largely surrounded by a shroud 36 through which the tines 31, 31A protrude. In a modification, (Fig. 9) the working height is set by relative movement of the drawbar 88 and an arm 82 secured to the gearbox 4, as set by a screwed spindle 98. The ground-wheel supporting arm 23 extends first forwardly from the wheel 24 and then rearwardly and upwardly.

Patent GB-347296-A (GB)
Title: Improvements relating to thermionic valve circuits
IPC: H04B15/00
Filed: 1929-10-30
Abstract: 347,296. Valve amplifying circuits. GREELEY, P. H., 2632, Garfield Street, Washington, U.S.A. Oct. 30, 1929, No. 33017. [Class 40 (v).] In a thermionic amplifier in which the grid circuit of one valve is in parallel with the anode impedance of the preceding valve hum is prevented by providing predetermined impedances between the plates of a pair of valves and the high tension source so that the plate circuit impedance of the first valve is as many times greater than the impedance of the following valve as the amplification factor of the valve. The arrangement also prevents the large plate current variations of the output valve from affecting the earlier valves. Fig. 1 shows valves T1, T2 having anode impedances L1, R3 and L2, R4 fed from a source E having an alternating component G. Fig. 4 shows the application to a high-frequency amplifier in which hum may be produced by the resistance of the choke L11. In this case a resistance R12 may be added to make the resistance of the plate circuit of T10 equal to the resistance of the plate circuit of T11 multiplied by the amplification factor of the valve. The invention is also applicable to transformer coupled valves, in which case the transformer in the output of the first valve has a primary winding of low impedance. The leads between the valves and the coupling elements, if long, are twisted together to prevent undesirable pick-up of relatively high-frequency currents which would otherwise produce a high-pitched whistle. Specification 326,859, [Class 40 (v), Wireless signalling &c.], is referred to.

Title: Improvements in or relating to electrical signalling systems
IPC: H04B1/66
Filed: 1937-12-01
Abstract: 482,267. Band - width compression. ELECTRICAL RESEARCH PRODUCTS, Inc. Dec. 1, 1937, No. 33178. Convention date, Dec. 2, 1936. Addition to 466,327. [Class 40 (iv)] In a system in which, as described in the parent Specification, signals indicative of the energy in a number of bands into which speech or other complex signal is arbitrarily divided and of the momentary value of the fundamental frequency, if any, are transmitted instead of the speech &c. itself, the transmission of these signals over a single circuit is effected with the aid of distributers instead of by carrier multiplex methods. As shown in Figs. 2 and 3, the signals, produced as in the prior system, pass to matching networks P0 .. P10 and integrating circuits 10 .. I10, which arrange for the distributer brush S to encounter on each segment a voltage representative of conditions since last the segment concerned was engaged rather than the instantaneous signal voltages existing at the moments of engagement. Additional brushes discharge the integrator circuits as soon as their record has been employed. At the receiving end, the signals are passed by distributer RD<1> to speech reconstituting circuits via filters F<1>30 ... F<1>40 arranged to prolong the effect of a signal during one rotation of the distributer but no longer. The relationship between distributer speed and signal frequency and the effect of leaving out the integrating circuits 10 &c. are discussed. In a modification, the discharging brush C is omitted and the transmission line is provided with resistances RS, R<I>S and condenser Cs as shown in Fig. 18, to cause any given signal to spread a little into the period allotted for the next. By the use of delay circuits it can be arranged that any signal comprises portions of the subsequent as well as the preceding signal, Fig. 19, (not shown). In a further modification, Fig. 20. the prolonging network in the line is omitted and the spread of one signal into the subsequent and preceding time periods may be looked after by delay networks D, 2D and attenuation pads LP arranged in 3 channels into which each channel is sub-divided. Isolating amplifiers are provided at IA. The lower part of this Figure shows a further development in which there is subdivision into seven channels to make the effect more closely analogous to that of the use of a sine-shaped scanning beam in television. The arrangement shown in this figure may have a discharging brush G similar to that shown in Fig. 2. The signals are D.C. signals and if the line cannot handle them in this form, a means may be provided to re-introduce the D.C. component at the receiving end.

Filed: 1928-11-13
Abstract: 318,192. Soc. Anon. des Ateliers d'Aviation L. Breguet. Aug. 30, 1928, [Convention date]. Fluid-pressure; disc.- Wheel brakes for aircraft which can be applied only when the tail skid is in contact with the ground are applied by compressed air which is admitted to the brake piping by a slide valve controlled by the tail skid, the slide valve being in series with a distributing valve under the control of the pilot. Compressed air from a reservoir 10 is admitted to a pipe 11 when a spring-loaded valve 8 is moved to the right by a rod 7 connected to a lever 5 pivoted at 6 and coupled bv a rubber cord 4 to the tail skid 2. The pipe 11 leads to a chamber 24, and when a valve 16 is lowered by movement of a lever 17 air passes through ports 25, 26 to an annular space 41 from which air passes through ports 39, 40 in a rotatable disc 37 to pipes 22, 23 leading to the brakes. A third port in the disc 37, which is rotatable by the handle 17 enables either brake to be applied without the other. When the valve 16 is raised the pipes 22, 23 are vented through ports 26 to an open space 34. The pressure fluid acts upon pistons 54 in cylinders 33 to move levers 55, 56 to press rings 28, 29 against discs 30 on the wheels, spring strips 31, 32 anchoring the rings against rotation and separating them when the pressure is released.

Filed: 1922-12-06
Abstract: 204,972. Siemens Bros. & Co., Ltd., Ferreira, L. de M. G., and Insell, R. J. Dec. 6, 1922. Signals and points, interlocking.-In order to adjust for wear of the members of a detector of the kind in which detecting members enter notches in detector bars, a frame 9 carrying the circuit-closing members 23 and the contact springs 18 is adjustable relatively to the detecting member. The plates 14 slide in the frame 9. Pivoted levers 13 engage slots in the plates 14 and are urged by springs 15 between the levers and the frames against the ends of links 32, the other ends of which bear in recesses in the arms 28 of bell-cranks. The arms 28 have rollers 31 co-operating with notches 36 in detector blades 1, 2, connected to the point-tongues. The other arms 27 of the bell-cranks co-operate with notches 35 in the locking bolt 3 or a part connected thereto so that the bell-cranks can only move when the points are bolted. The frames 9 are held by screws 11 passing through slotted holes to permit adjustment, which is effected by means of a screw 17 abutting against the casing. A slight movement of the frame 9 carrying the lever 13 causes the lever to rock about the end of the link 32 to produce a larger movement of the plate 14 in the opposite direction to that of the frame.

Title: Foamable thermoplastic polymer granules and method of making
IPC: C08F2/44
Filed: 1961-09-21
Abstract: Free flowing foamable thermoplastic polymeric particles comprise a thermoplastic polymer and a volatile organic fluid foaming agent which is substantially not a solvent for the polymer, which polymer particles have a reduced tendency of clamping by virtue of the presence of a coat of a fluid polysiloxane which is not sufficiently compatible with the thermoplastic polymeric composition to act as a good plasticizer. The particles may be partially foamed or prefoamed with the capacity of further increasing in volume in a suitable foaming treatment.  They may also contain flame-retarding agents e.g. dibromotetrachloroethane. In the preferred siloxanes all the units may be (CH3)2 SiO or a minor proportion of C6H5(CH3) SiO or (C6H5)2 SiO units may be present.  The thermoplastic polymers can be derived from monomers of the formula ArCR=CH2 in which Ar is a hydrocarbon or nuclearly halogen-substituted hydrocarbon radical of the benzene series and R is hydrogen or a methyl radical.  The coating of the granules may be effected by applying a solution or an aqueous emulsion of the fluid polysiloxane and then airdrying them. Aliphatic hydrocarbons and chlorofluorocarbons are suitable foaming agents. In the examples polystyrene beads are used.  They are coated before or after prefoaming and then put in a mould and converted to cellular bodies.ALSO:Free flowing foamable thermoplastic polymeric particles comprise a thermoplastic polymer and a volatile organic fluid foaming agent which is substantially not a solvent for the polymer, which polymer particles have a reduced tendency of clumping by virtue of the presence of a coat of a fluid polysiloxane which is not sufficiently compatible with the thermoplastic polymeric composition to act as a good plasticizer.
