Title: Processes for coating metal surfaces
IPC: C23C22/60
Filed: 1964-09-23
Abstract: A zinc or zinc alloy surface is coated by dipping, spraying or brushing it with an aqueous alkaline solution containing complexed metal ions e.g. magnesium, cadmium, aluminium, tin, titanium, antimony, molybdenum, chromium, cerium, tungsten, manganese, cobalt, iron or nickel.  The complexing agent may include an inorganic sequestering agent e.g. cyanides, phosphates or ammonia or an organic chelating agent e.g. dicarboxylic acids such as tartaric, malonic and fumaric acids, amino acids such as glycerine, hydroxy carboxylic acids such as citric, glucoric and lactic acids, hydroxy aldehydes such as acetyl acetone, polyhydroxy aliphatic compounds such as sorbitol and 1,2 ethanediol, phenolic carboxylic acids such as phthalic and salicyclic acid, amine carboxylic acids such as E.D.T.A., polyamines acids such as diethanolamino methane phosphonate, and sodium ligno-sulphonate.  The alkaline solution may be sodium hydroxide, and a surface active agent may be used.  The treated surface may be rinsed with chromic acid (0.01% to 0.5% by weight CrO3).  Were part of the surface is iron, e.g. in a partly galvanized article, the alkali solution may act as a cleaning treatment on the iron surface prior to phosphating with a zinc or alkali metal phosphate coating solution.  In an example a solution containing (per cent by weight) 0.76 Na OH, 0.1 sodium hexahydroxy heptoate (complexing agent), 0.0037 iron, added as ferric nitrate nonahydrate, and 0.0024 cobalt nitrate hexahydrate is sprayed at 160 DEG F. on steel panels for 1 minute. The panels are then rinsed in hot water for 30 secs and then in an aqueous rinse containing 0.04 trivalent chromium and 0.1 hexavalent chromium, pH 4.5 for 30 secs. The panels are then dried and painted with melamine-alkyd paint.

Title: System for controlling the movement of cars along a track
IPC: B61L23/14
Filed: 1969-08-05
Abstract: 1284609 Train control system DASHAVEYOR CO 5 Aug 1969 [9 Aug 1968] 39219/69 Heading B7N Driverless rail vehicles travelling full in one, e.g., left direction and empty in the other, e.g., right direction on a single track are controlled by signals in block defining track loops 42, 44, each associated with one direction of traffic movement. The vehicles are energized from a 3-phase supply via power rail conductors 37-39 and the signalling control arrangement 48, 50 in each block is energized from one phase of the supply via a circuit including signal rail conductor 40 which is insulated at its ends and extends over the length of the block. On entry of a vehicle into a block, e.g., the block defined by loops 42B, 44B, the power supply to the signal control arrangement of the block is cut off by a short-circuit connection on the vehicle engaging a rail conductor of the signal control arrangement supply phase and the rail conductor 40. Each control arrangement includes two relays K1, K2 (not shown) controlling respectively the supply of signalling current from source 82 to the loop 42 of the block to the left and to the loop 44 of its own block; and each vehicle includes detecting means for holding off braking when signalling current is picked up from the loop associated with its direction of movement. The cut-off of the power supply to the control arrangement de-energizes relay R1 and also via contacts of the relay, the R2 relays of the two blocks to the right of that occupied. Thus if the occupation of the block B is caused by an empty train vehicle moving to the right then the loop 42A of the block A to its rear is de-energized thus braking to a halt any following train entering that block and if the train is loaded and moving to the left then the two loops 44C and 44D (not shown) in the blocks C + D to its rear are de-energized, thus braking a loaded vehicle (which takes further to come to a halt) entering block D. The frequency of the signalling current may be varied to slow the vehicles at bends in the track, approach to points &c.

Abstract: 1,085,236. Liquid level indicators. WILLIAM & JAMES (ENGINEERS) Ltd. Sept. 30, 1964 [Oct. 5, 1963], No.39305/63. Heading G1H. [Also in Division F2] A valve comprises a main valve member and filter element assembly 12, 14 which is withdrawable from a valve body 1, and so arranged that when the valve is open flow through the valve passes through the element, and an isolating valve member 23 which automatically closes to prevent leakage from the valve when the assembly is withdrawn. The member 12 is moulded from synthetic plastics material and has a closure face 16 which is operatively associated with a face 17 of the body 1, to control the flow of liquid from an inlet 2 to an outlet 7, upon axial movement of the member 12 produced by rotation of the assembly 12, 14. The filter 14 is directly connected to a further closure 13 which controls the flow from the inlet 2 to an outlet 8 connecting with a level indicator 40. The member 13 can be moved axially off its seat against the action of a spring 29 by a knob 31. The spring 29 also urges the member 22 to the closed positions so that when the assembly 12, 14 is removed for cleaning, the member 22 closes on to its seat. A U-shaped stirrup 30 prevents the assemblies 12, 14 from being inadvertently removed from the body 1, but axial movement of the member 13 causes cam surfaces 33, 34 to retract the stirrup 30 and allow the assembly to be withdrawn. The level indicator 40 may be a Bourdon gauge which may be connected directly to the upstream passage of the main valve 12.

Abstract: 1446447 Quick hitch mechanism for vehicles JEAN WALTERSCHEID GmbH 15 Aug 1973 [23 Aug 1972] 39560/73 Heading A1P An implement is connected to, e.g. a tractor, lorry or a building contractor's machine by means of two co-operating parts, one of which comprises a transverse plate 22, whilst the other comprises at least one angularly displaceable member 2, Fig. 5 which is pivoted from a position in which it extends towards the plate, Fig. 5, to an upright position upon contact with the plate. The or each member 2 is provided with an alignment member which co-operates with a corresponding alignment member on the plate and the implement and tractor are retained in position by a quick release locking arrangement carried by the parts.  Upon lowering the tractor power linkage 12, 13, parallel and vertical links 3, 4 of member 2 are fed to pivot towards the implement of Fig. 2 about a common shaft 5. Upon driving the tractor towards the implement, rollers 8 at the top of the links engage the transverse plate 22 and ride up it until a V-shaped notch 9 on a pivoted alignment plate 6 engages a cooperating alignment notch 28 and pivoted hooks 46, 47 engage the bottom of the transverse plate 22. Further movement of the tractor connects p.t.o. shaft coupling 19 with transmission shaft coupling 23, and notched bolt 17 in aperture 26. The notch 18 is engaged by slidable catch 48. Finally a bar 16 connected to the tractor power linkage engages between arms 30 and lugs 31 so that the implement e.g. a manure spreader, plough, winch, pump, power generating unit, cable or fertiliser spreader can be moved with the tractor. Unhitching is performed by the reverse operation once bracket 49 has been raised.  The links 3, 4 are mounted for limited lateral angular movement on shaft 5. If the tractor is on a bank the side flanges 20, 21 then cam the links 3, 4 into their proper position. A similar quick hitch may be made at the front of the vehicle and signals may be generated to signify correct connection. The implement transmission shaft may be telescopic.
