Title: Improvements in and relating to an agricultural machine adapted to be suspended on a tractor
IPC: A01B59/06
Filed: 1968-03-12
Abstract: 1,223,913. Agricultural machines. LANDBOUWWERKTUIGEN-EN MACHINEFABRIEK H. VISSERS N.V. 12 March, 1968 [15 March, 1967; 14 Sept., 1967], No. 12084/68. Headings A1B and A1P. An agricultural machine is connected to the two lifting links 29 of a tractor power lift mechanism by links 35 connected to the implement frame-members 3 each of which is swingable with respect to the implement frame 6 about bolts 37. The implement oscillates transversely of the machine and the arrangement allows movement of the implement with respect to the tractor in longitudinal directions limited by buffers 39. In another embodiment (Figs. 4, 5, not shown) the links (35) are replaced by a transverse rod (40) having lugs (36) on each side and connected to the implementframe through a vertical pin (41) and the studs (42) are surrounded by springs (43). Means can be provided on the rod (40) for attaching a second implement. The implement is driven by the tractor power take-off shaft connected to the implementdrive-shaft 15 through a cardan coupling 14 positioned vertically above the pin (41).

Title: Improvements in small spring return valve- or damper-operating motors
Inventor: SAWYER WILFRID ALBERT
IPC: H02K7/10
Filed: 1949-05-05
Abstract: 664,090. Motor - driving arrangements. RHEOSTATIC CO., Ltd. May 1, 1950 (May 5, 1949], No. 12163/49. Class 35. In a spring-loaded electric motor assembly the motor 1 is connected to the spring 15 through gear-wheels 4 and a friction clutch comprising a disc 6 on a shaft 5, discs 8, 9 and plate 10, 11 connected to the spring mechanism at 12. The spring is connected to the discs so that it exerts a constant rotative force on the shafts. When the motor is energized, windings 20, 21 are in parallel, a crank 18 is operated, and the spring is compressed. At the end of the required run a cam operates a switch 24 to disconnect one winding and subsequently operate a switch 25 to connect the winding in series so that in the stalled position, the torque of the motor balances the effect of the spring. When the motor is de-energized the crank 18 is returned to its original position by the spring but to prevent abrupt stoppage of the gear train 14 and motor 1, after the plates 10, 11 have been stopped by a nut 26, the disc 6, gearing 4 and motor 1 may run on slightly against the action of the friction clutch.
Patent GB-179194-A (GB)
Title: Improvements in method for separating the constituents of emulsions, or emulsion-like mixtures
IPC: B01D17/02
Filed: 1922-05-01
Abstract: Emulsions are caused to separate into their constituents by being passed into or absorbed in and subsequently expressed from the pores of a material, such as cotton waste, which exerts a capillary action thereon, and which is preferably of a spongy nature.  The process is suitable for decomposing aqueous emulsions of water-gas tar and coal-gas tar, and certain petroleum emulsions known as "brown sediments."  The Specification as open to inspection under Sect. 91 (3) (a) refers to apparatus for carrying out the process.  One form comprises a horizontal cylinder divided into annular compartments lined with the porous material and containing rolling weights which compress the material as the cylinder rotates.  The emulsion is fed into one end of the cylinder and flows through the successive compartments, the heterogeneous mixture of the constituents leaving at the other end.  Another apparatus consists of a centrifugal separator containing cotton, the speed of the apparatus being periodically varied to cause alternate absorption and expulsion of liquid.  A third device comprises an endless moving belt of cotton, which dips into the emulsion at one point and is squeezed between two pulleys at another point.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to travelling wave amplifier arrangements
IPC: H01J25/38
Filed: 1959-04-13
Abstract: 850,577. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 13, 1959 [April 30, 1958], No. 12401/59. Class 39(1). In a travelling wave amplifier there are a plurality of delay lines each having a respective associated electron beam, the electron beams not being coupled to one another but the delay lines being coupled to one another and an equal plurality of cavity resonators, terminating the delay lines and each traversed by an electron beam means to feed a single wave to all the delay lines and means for extracting amplified energy from the resonators, the electron beams having slightly different velocities from one another to increase the frequency pass band of operation. The electron beams have separate guns, and the delay lines and output resonators are coupled by transverse apertures. There may be more than two systems side by side. Each system is equivalent to a disc loaded waveguide or it is stated can be replaced by other types of delay line. The two Wehnelt electrodes of the two electron guns and the two cathodes carry different D.C. potentials. The lossy coating 24 completely absorbs the waves travelling along the delay lines and the density modulated electron beams induce an output in the cavity resonators 13. The output resonators have tuning screws 14 which are adjusted to give the desired band width in the output, operation being in dispersive regions for both electron beams. The coupling apertures 18, 19 widen the pass band since they lower the Q. The guns have indirectly heated cathodes 6, 7 Wehnelt electrodes 8 and a common anode 10. In a modification there may be several cavities in series in each output system. Specification 660,792 is referred to.

Title: Improvements in grinding and polishing machines
IPC: B24B19/00
Filed: 1934-04-25
Abstract: 429,314. Grinding and polishing articles of irregular form. KELM, A. F., 24, Furstenweg, Neubabelsberg, Berlin. April 25, 1934, No. 12511. [Class 60] A machine for grinding and polishing articles such as spoons comprises a head carrying holders for the articles which is rotatable stepwise to bring them in succession against a grinding wheel, and means for imparting to the article, when in contact with the wheel, a reciprocating movement tangential to the wheel, a tilting movement in the direction of the length of the article, and a reciprocating movement parallel to the axis of the wheel. In addition, the article may be rocked approximately about its major axis. In the machine shown diagrammatically in Figs. 2 and 4, the articles 16, such as spoons, are mounted in carriers on three arms 32 jointed to arms 15 pivoted on an intermittently rotatable head R. The arm 15 in operative position is oscillated by a rotating cam 14 of adjustable throw which engages a roller 30 on the arm, this causing a reciprocation of the arm 32 substantially in the direction of its length and so moving the article 16 tangentially against the wheel B. The tilting movement of the article is produced by a fixed cam 36 engaged by a roller 33 on the arm 32, which is thus given an angular movement as it reciprocates. The reciprocating movement of the article across the face of the wheel and parallel to its axis is produced by an axial reciprocation of the head R through the agency of an eccentric 9 connected by a fork 10 to a collar on a shaft 22 on which the head is mounted. The step-by-step rotation of the head R which brings the carriers in turn to the operative position is produced by a cylinder 12 connected to it by a dog coupling and intermittently turned, through gears 21, 29a, by a rotating shaft 18, which is coupled and uncoupled by a clutch 19 operated by a cam 20a. The rollers 30 on the arms 15 which are not in operative position are lifted from contact with the rotating cam 14 by engagement with a fixed cam 13. Fig. 6 shows, in addition, the means for rocking the article about its major axis, and comprising a rotating gear concentric with the cam 14 and rotating a gear 38 concentric with the roller 30 on the arm 15. The gear 38 causes, through a link 39, a bellcrank lever 40 pivoted on the arm 15, and a link 42, the reciprocation of a nut 43 engaging the threaded end of a spindle 45 which is rotatably mounted on the arm 32 and to which the work 16 is attached. The spindle and work are thus caused to oscillate about their longitudinal axes. The entire apparatus is rotatable about a vertical axis and by means of a spring F, Fig. 2, is caused to hold the article 16 with a yielding pressure against the wheel B.
