Abstract: 1,054,187. Electromagnetic relays. WESTERN ELECTRIC CO. Inc. Aug. 1, 1963 [Aug. 7, 1962], No. 30552/63. Heading H2B. [Also in Division C7] The contact surfaces of the magnetic reeds of a sealed magnetic contact device are formed by applying a first layer of gold thereto, applying a second layer of a second metal, e.g. silver, palladium or rhodium to the first layer and heating the reeds for 10-60 minutes at a temperature (e.g. 800-950 C.) just below the melting point of the layer having the lowest melting point to ensure diffusion of the layers. The surface layer of each reed is said to be an alloy of the second metal and gold and an intermediate layer between the surface layer and the magnetic reed is said to be an alloy of the second metal, gold, and magnetic reed material. The reed may be a nickel-iron alloy. The gold layer may be heated to a temperature of 800-950o C. prior to the application of the second metal layer and the heat treatment.

Abstract: 1,054,622. Polyfluorinated aromatic compounds. R. N. HASZELDINE, A. R. PARKINSON and J. M. BIRCHALL. Dec. 17, 1962 [Sept. 18, 1961], No. 46324/62. Divided out of 1,054,621. Heading C2C. The invention comprises a compound having the general formula R*.R in which R* is a polyfluorinated aromatic (including heterocyclic) radical containing fluorine atoms on at least half of its aromatic ring positions, at least one aromatic ring carbon adjacent to the R- attached carbon atom carrying fluorine. R is an aromatic (including heterocyclic) radical having hydrogen attached to at least half of its ring positions and free of substituents reactive with a hydrazine group and the R and R* radicals are connected to each other directly through carbon atoms each of which is in an aromatic ring. The compounds R.R* may be made by oxidizing a fluorinated hydrazine R*, NH.NH 2  in the presence of a compound of formula RH, the -NH.NH 2  radical in the hydrazine and the H atom in the RH compound being attached to aromatic nuclear carbon atoms. The reaction may be effected in the range - 30‹ to 180‹ C. and a wide variety of oxidizing agents may be used. The novel compounds may be reacted with a reagent containing Y, where Y is a hydroxy or alkoxy ion, an amino or substituted amino radical, a sulphhydryl or sulphalkyl ion, or a hydrazino or substituted hydrazino radical, to replace a fluorine atom in the perfluorinated portion of the compound with the Y radical. The compounds R.R* may be reacted with a reagent containing a radical or atom X, where X is a nitro or sulphonyl radical or a halogen atom, to replace a hydrogen atom in the essentially hydrocarbon part of the molecule with the X radical. The compounds R.R* may also be made by subjecting a mercury compound R*.Hg.R* or R*.HgX, where X is a chlorine, bromine or iodine atom or lower alkanoate radical to thermal or photolytic activation in the presence of a compound RH.

Abstract: 1,233,460. Hydrostatic transmissions. ROLLSROYCE Ltd. 19 July, 1968, No. 34462/68. Heading F2D. In a hydrostatic transmission having a fluid pressure supply 12 and fluid control means in flow series and supplying at least two fluid motors, the fluid control means includes an inlet from the fluid pressure supply, a fluid metering supply device 16, 20 connected to each fluid motor 22, 24, 26, 28 and a fluid metering balance device 18 connected to the outlets of the fluid metering supply devices. An enginedriven pump 12 supplies the metering devices 16, 18 and 20, each of which comprises two intermeshing gear wheels, the device 16 supplying fluid to motors 22, 24 which drive the vehicle's front wheels and device 18 supplying fluid to motors 26, 28 which drive the rear wheels. The flow from metering device 18 is split evenly between the front and rear wheels so that the total flow to the front and rear motors is 33<SP>1</SP>/ 3 % and 66<SP>2</SP>/ 3 % respectively. If the front wheels tend to over-run the pressure drop at the motor inlet causes the now from device 18 to be increasingly diverted to motors 22, 24 until the combined flow from devices 16, 18 is insufficient to maintain this pressure at which point non- return valve 32 is closed and the system operates with the front and rear wheels positively driven. The system operates similarly if the rear wheels tend to over-run.

Each unit of the inverted-V version of the information store, forming part of the system for transferring information between a vehicle and apparatus adjacent its track described in parent Specification, is modified to prevent its tube shaped member 35 being shifted from its one stable position to the other due to sudden acceleration or shock movement of the vehicle. The downwardly directed arms 32, 33 of the V which terminate in pockets 5, 6 for the tubeshaped member 35 are curved in elevation to assist transfer of the tube by the magnetic writing means and the apex of the V is formed with a circular profile 36 to provide a ridge 37 which returns the tube when bounced out of pocket 5 back to the same pocket. The pockets 5, 6 may be joined by a small conduit 43 and each provided with a small amount of liquid to damp movement of the tube. The ridge 34 between the pockets may be provided with a non-magnetic, heavy cylinder 44 of e.g. brass which runs in guides 46 formed in the sides of the unit and extending towards the apex of the V. This cylinder moves during shock movement of the vehicle to block the passage for the tube 35 between the two pockets.

As a sheet passes the roller 15, its longitudinal margins are raised by surfaces 21, 23 of fixed and movable guides 22, 24 to stiffen the sheet. When wider sheets are to be delivered, the assembly 17 including the roller 15 and guide 24 is moved laterally to align the roller 15 with a second drive roller 12. A rod 92 is manually pushed inwards and moves a lever 82 out of a detent 77 of a member 43 of the assembly 17 also through a cable 66 moving the roller 15 out of engagement with the roller 11. The assembly is then moved transversely by means of a handle 96 until the lever 82 moves into a second detent 76 and the roller 15 moves into engagement with the roller 12. When the lever 82 is raised, a switch 95 stops the sheet-procuring machine. The rollers 11, 12 may be replaced by one elongated roller, the position of the roller 15 being infinitesimally variable, or there may be more than two drive rollers, detents and positions of the roller 15.

In the course of a revolution of an eccentric 15, a hole is bored in a brush back 10 and at the same time motion is transmitted from the support 11 which moves along bars 13 to the drilling tool via rods 20 and 16 which are connected in such a way that the displacement of the drilling tool is twice that of the support. Brush backs 10 are held in a magazine by a gate, rotation of the carrier 7 causes a striker 33 attached to the workholder to push the lowermost brush back out of the magazine, said brush back being held in the workholder by two angle shaped gripping arms (37) Figs. 8 and 10 (not shown). The magazine undergoes limited rotary movement with the rod against the action of a spring F.
