Patent GB-1578123-A (GB)
Title: Palladium catalysis
IPC: C07C53/126
Filed: 1976-05-21
Abstract: During the use of palladium catalysts consisting of metallic palladium deposited in solid, porous, granular supports, these catalysts must have a low specific activity per unit area of deposited metal. To overcome this deficiency at least partially, these catalysts are prepared by depositing a palladium compound vapour onto a solid, porous, granular support and during this deposition the support is maintained at a temperature above the decomposition temperature of the palladium compound. Thus, the palladium rests on the outside of the support particles and is deposited only in the openings of the pores which have a diameter greater than 50  ANGSTROM . <IMAGE>

Patent GB-1292779-A (GB)
Title: Rapid frame synchronization of video tape reproduce signals
IPC: H04N5/95
Filed: 1971-04-19
Abstract: 1292779 Automatic speed control of video tape machines AMPEX CORP 19 April 1971 [16 Feb 1970] 21352/71 Heading G3R The invention relates to a means of synchronizing two signals each of which is composed of a train of low frequency pulses superimposed on  a train of higher frequency pulses. Such signals are for instance recorded on the control track on a transverse scan video tape machine. Two counters respectively count the high frequency pulses of each signal following a low frequency pulse and the difference, between the two counts is used to correct the phase error. Thus, in Fig. 1, a counter 23 counts the high frequency replayed pulses and is reset to a predetermined value on the arrival of each low frequency replayed pulse. On the arrival of a low frequency reference pulse from a source 19 a counter 24 takes over the count then accumulated in counter 23 and continues the count; counter 24 can thus continue after counter 23 is reset. A counter 21 counts high frequency reference pulses from 19 and is reset by each low frequency reference pulse. A subtractor 28 and digital to analogue converter 31 provide an error signal proportional to the difference in counts. Means may be provided to reset the counter 23 after the maximum possible count to avoid spurious high counts due to loss of a replayed pulse due to tape drop out or editing. In a tape transport system, by the above means frame synchronism is first achieved. As soon as the difference count from subtractor 28 reaches a predetermined minimum value the system is switched to a fine synchronizing mode in which the high frequency pulses are brought into phase synchronism.

Abstract: 703,198. Agricultural implements. CHARRUES MELOTTE SOC. ANON. Sept. 11, 1951, No. 21377/51. Class 6 (1) A one way plough for attachment to a tractor comprises a leg 21 pivotally mounted on a lifting crossbar 13 which raises the working plough, the leg being formed in two parts connected by a spring hinge 24. The leg is retained out of operation by a spring 31 attached through a rod 30 to a bracket 26 pivoted on the leg 21. The leg is brought into contact with the soil by a hand-lever 11 attached to the leg through a link 18 and the forward movement of the tractor causes the leg to straighten raising the working plough and tensioning the spring 31 which exerts a thrust on the leg in opposition to the spring of the hinge 24 to bring the leg back into its original position. The spring 31 is contained in a tube 9 secured to an axle 32 mounted on the tractor, the lever 11 being mounted on the tube 9. The working plough is held in the raised position by the engagement of notches 7 in a bar on a member 1 on the tractor. Various means are described for limiting the angular rearward displacement of the leg.

Abstract: 381,270. Folding aeroplane wings. COMPER AIRCRAFT CO., Ltd., COMPER, N., Hooton Park Aerodrome, and SPENCER, M. H., Halewood, Street Hey Lane, Willaston, both in Wirral, Cheshire. July 29, 1931, No. 21706. [Class 4.] An aeroplane wing is connected at its root to a disc which can turn about a transverse axis on another disc hinged to the machine frame to enable the wing to be turned out of its plane before being folded back against the fuselage, the wing being supported during folding solely by this connection. The fuselage, wing stump or central wing section on each side of the machine has bearings 1, 2 mounted on the framework defining an inclined axis 9 about which the wing can fold so as to be clear of the tail planes. Mounted on these bearings is an annular disc 16, Fig. 3, having flanges 17, 18 against which rests a second disc 21 having flanges 22, 18a. The discs are held together by bolts 25, 26 passing through slots 23, 24 in the disc 21 and carrying rollers 31 bearing on the surface of the disc 21. The wing is secured to the disc 21 between its spars so that after releasing securing bolts on the spar ends it can be swivelled an amount limited by the slots 23, 24 before folding it and the two discs about the axis 9. The amount of swivelling may be adjustable. The part of the wing root behind the front spar is slightly extended to fill a gap in the wing stump during flight, this gap accommodating the thickness of the wing root when folded. The aileron control rod 42 has a universal joint 41 situated at the intersection of the axis 9 and the axis of the discs.

Abstract: 1504394 Mine conveying system GEWERKSCHAFT EISENHUTTE WESTFALIA 21 May 1975 [18 June 1974] 21962/75 Heading B8E [Also in Division B7] In an underground tunnel driving installation, a trolley vehicle 14 having holding means 22 for transporting curved lining sections 16 is adapted to receive such sections 16 when passing over a first storage station 19 for the sections adjacent a tunnel entrance 17 and to deposit the sections at a second storage station 20 adjacent a tunnel erecting means 18 at the forward end of the tunnel. Forward of the erecting means 18, by which the lining sections 16 are fitted about the tunnel wall, is a cutting head 12 removing from a working face debris material which is delivered by a conveyer 13 to a container 21 of the vehicle 14. The container 21 carries vehicle wheels 33 between which are locating and retaining members 34 constituting the holding means 22 for the sections 16. The first storage station 19 comprises a pair of parallel rails 23 which have camming surfaces 27 engaging rollers 28 so that actuation of piston-and-cylinder units 24 causes raising or lowering of the rails 23. When in their raised position, the rails 23 receive sections 16 from a displaceable table 31 at the tunnel entrance, and and the vehicle 14 can be driven over the station 19 without contact between the sections 16 and members 34. The rails 23 are then lowered so that the sections 16 are supported by the members 34 for transport to the second storage station 20. During its approach to the station 20, vehicle 14 depresses a lever 37 which is spring biased to pivot upwardly and thus block the return path of the sections 16 so that the sections are transferred to rest on rails 36 at station 20 when the vehicle 14 moves back towards the tunnel entrance. The vehicle 14 can be propelled in any suitable manner such as by means of a winch cable, and its wheels 33 run on L-shaped rails 44 which are movable as the tunnel advances by virtue of a pivotal attachment at 43 to a frame 40 associated with the rails 36, a crane 39 and the erecting means 18. Instead of raising and lowering the rails 23, stationary rails 23 could be employed to cooperate with a holding means 22 which can be raised and lowered.
