Title: Electrochemical Process for the Surface Treatment of Titanium or Alloys thereof or Niobium or Tantalum
Inventor: PIONTELLI ROBERTO
IPC: C25D11/26
Filed: 1967-04-24
Abstract: 1,175,613. Titanium alloys; electrolytically modifying metal surfaces and plating. R. POINTELLI. April 24, 1967 [April 23, 1966; Feb.9, 1967], No.18830/67. Headings C7A and C7B. The surface of Ti, Ti alloy, Nb or Ta is electrolytically modified in an aqueous solution of more than 350 g/1 NaOH or KOH, to prepare it for metal coating e.g. by electro-plating or chemical plating with Cu, Ag, Au, Ru, Rh, Ir, Pt, Cr, Ni, Zn, Pb or Pb-5b. The treatment may be effected with D.C. at 30-80 volts and C.D. 10, 000-50, 000 amp/m<SP>2</SP> using surface as anode and Fe, steel or Ni as cathode; or with A.C. at 25-30 volt and C.D. 50, 000-80, 000 amp/m<SP>2</SP> using the same material as counter-electrode. Salts of Pb, Sn, Sb, Bi, Ta, T1, As, Cu, Al, alkaline earth metals, sodium silicate or phosphate and/or borax may be added to the solution. After the above treatment and before metal coating, the surface may be further electrolytically modified in an aqueous acid solution of HC1, H 2 S0 4 , H 2 SO 4  + NaCl, HClO 3 , HBF 4 , H 2 SiF 6 , MF, HNO 3 , acetic and/or sulphaminic acid; graphite, Sb-Pb or the same material may be used as counter-electrode with A.C. of 50c/s at 1À5-8 volts and C.D. 500- 10, 000 amp/m<SP>2</SP>. The coated treated surface may be heated between 400 and 600C. under vacuum or argon without detachment of the coating. Either electrolytic modification may be effected without immersing the surface by connecting it, together with a cylinder or plate counter-electrode moving with respect to and spaced from the surface, to a current generator, a layer of the solution being maintained therebetween, preferably impregnated into a pad of flexible, porous, insulating material e.g. cotton coated on the counter-electrode. Sulphamic baths may be used for final electrodeposition of Rh, Ru, Ni, Zn or Pb. Other baths specified contain: (1) antimony tartrate, tartaric acid and lead carbonate for electro-depositing Pb containing 2% Sb; (2) 125 g/1, CuSO 4 , 50 g/1 H 2 SO 4  and 50 cc/1 ethyl alcohol for Cu; (3) ammonium-chloro-iridate, S0 4  anions, Na ions and ammonium fluoride for Ir; (4) 2 g/1 Pt (as chloroplatinic acid), 20 g/1 (NH 4 ) 2 HP0 4  and 100 g/1 Na 2 HPO 4  for Pt; (5) 260 g/1 rhodic acid, 2À5 g/1 H 2 SO 4  and 5 g/1 HF for Rh.

Title: Braking systems
IPC: B60T8/30
Filed: 1973-04-19
Abstract: 1423718 Regulating braking by vehicle load sensing AKEBONO BRAKE INDUSTRY CO Ltd 19 April 1973 [19 April 1972] 18966/73 Heading F2F In an hydraulic braking system for the rear axle of a vehicle and in which there is provided load-sensing means including a load-sensing lever 4 for detecting the load carried by the rear axle and which controls an hydraulic fluid load-sensing valve 1 for regulating the hydraulic fluid pressure supplied to the rear wheel brakes during braking in dependence upon the load carried by the rear axle, there is provided an hydraulic fluid by-pass valve 19 for by-passing the load-sensing valve and which is normally held closed by a by-pass lever 17. The latter is pivotably mounted on a fixed part 3 of the vehicle body or chassis and there is biasing means, i.e. a spring for connecting the lever 4 and the rear axle of the vehicle to bias the lever in one sense and biasing means, i.e. a spring 9, for connecting the lever 4 and the lever 17 to bias the lever 4 in the opposite sense so as to urge the lever 17 to a position in which the by-pass valve is closed. Failure of the loadsensing means including the spring 9 allows the lever 17 to pivot to permit the by-pass valve 19 to open. In operation, pressurized fluid from a master cylinder enters inlet chamber 43 of the valve 1 to pass through the passage 35 of the stepped piston 13 past the ball or disc valve 37 and to the chamber 44 and the outlet 50 connected to the rear wheel brakes. An increase in fluid pressure and acting on the differential areas of the piston 13 overcomes the load applied by the lever 4 to the piston to cause the piston to move away from the plug 42 whereby the valve 37 closes the passage 40 and a further increase in fluid pressure causes the piston to move towards the plug so that fluid in the chamber 43 passes to the chamber 44 via the gap between the valve 37 and seat 39; the fluid pressure on the brakes gradually increases as this operation repeats. In the by-pass valve 19 the lever 17 bears on a piston 22 so that a ball 29 normally obstructs the passage 28 of a plug 25 whereby the chambers 26, 30 are not connected. With failure of the load-sensing means such as breakage of the spring 9, the force exerted on the piston 22 drops and, during braking, fluid pressure in the chamber 30 acts on the piston to move the latter downwards while fluid pressure in the chamber 26 connected to the master cylinder opens the ball valve 26 so that fluid admitted to the chamber 30 is supplied to the brakes via a passage 52 and the outlet 50.

Abstract: 569,517. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Nov. 26, 1943, No. 19765. Convention date, Nov. 30, 1942. [Class 40 (v)] A valve oscillator adapted for use over extremely wide frequency ranges and at frequencies so high that inter - electrode capacitances have to be considered, comprises a coupling between the anode and grid consisting of two series impedances having inductive reactance and shunted by an impedance which may be a valve inter electrode capacity and have a capacitative reactance and a fourth impedance having a capacitive reactance connected to the junction of series connected reactances and to the valve cathode. The Figure shows series reactances 18, 20 and a parallel reactance 22 and reactance 24 connecting the junction of reactances 18, 20 to the valve cathode. The anode supply includes a choke 28 while a grid-leak 30 and condenser 32 are provided. Alternatively, if the high tension supply is series fed it must be by-passed so as to be effectively short-circuited at the frequency of oscillation. At high frequency the capacity 22 may be constituted by the grid anode capacity of the valve. The reactance elements 18, 24 may consist of separate co-axial lines one having an inductive and the other capacitative reactance. The reactance 20 may be the lead connecting the grid of the valve to the common point between the reactances 18 and 24 and may include a condenser but has an overall resultant inductive reactance. The additional feedback provided by the capacitative reactance 24 permits higher frequency to be obtained than in the '' Colpitts " oscillator in which the inherent anode cathode and grid-cathode capacities provide the limiting factors. In this way an oscillator is provided in which inter-electrode capacities at the higher frequency are not the sole frequency determining factor. Specification 529,291 is referred to.
