[Also in Division C7] In a process for producing a thin-film circuit on a glass substrate 1, conductors 2, 3, contact areas 4 ... 7, and a first capacitor electrode 8, are first formed by the vapour deposition in vacuo of an alloy comprising 50% Fe and 50% Ni at c. 300 C. Thereafter are deposited in succession a capacitor dielectric layer 9, e.g. SiO, a second capacitor electrode 10 of the same alloy as the first, and finally resistances 11, 12 and a monitor resistance 13, of Ni-Cr alloy. The latter alloy may also be applied as a solder resist to electrode 10, or some other resist may be applied. In a modification, after the deposition of conductive areas 2 ... 8, resistances 11 ... 13 are deposited and the device is then tempered, preferably in an oxygen-containing atmosphere, at 150-400 C. Next, dielectric layer 9 and electrode 10 are deposited. Conductive areas 2 ...7 are then tinned, as at 14, the oxide layer formed thereon during the tempering step being previously removed by a suitable fluxing agent, and electrode 10 again being protected, as by Ni-Cr alloy. During the deposition of the resistances 11, 12, their value is measured by monitoring resistance 13 which is deposited simultaneously. The production of a circuit comprising only resistors and conductors is also described. Substrate 1 may alternatively comprise ceramic or a synthetic resin.

In a process in which a lubricant coating is formed on a succession of metal surfaces by treating the surfaces with a fatty acid soap lubricant composition maintained in a tank, the lubricant composition is withdrawn from the tank during the process, is purified of impurities by centrifuging, is deaerated and reintroduced in to tank. In the arrangement shown lubricant from article immersion tank 1 drains via pipe 3 to a centrifugal purifier 5. Water and/or steam may be added via pipes 2 and 4 respectively. In the purifier, purified lubricant composition is removed by skimmer 7 and fed to 'thin film' type deaerator 11 from whence it drains back to tank 1. The heavy metal soaps and other impurities 10 are drained from the purifier through outlet 8. The flow rate through the purifier is at least 1 gal. per minute and preferably from 2 to 6 gals. per minute and the centrifuge may be rotated at from 1000 to 2000 r.p.m. In one application, steel blanks for cold forming which had been coated with zinc phosphate coating solution were given a lubricant coating by immersion for 5 minutes in a solution of 0.5 pounds sodium stearate soap per gallon at a temperature between 65 and 85‹C. A portion of the lubricant solution was drained from tank 1 and passed at the rate of 2 gallons per minute through a bowl type centrifuge rotating at 1400 r.p.m. Lubricant solution removed from the centrifuge by skimmer 7 was then spread as a film about 0.5 cm. thick over the spreader plate 13 and returned to tank 1. Lubricant material analyzed before and after centrifuging showed iron contents of 0.030% and 0.025% respectively.

A metal forming machine comprises a bed upon which driven camshafts are arranged, a plurality of forming slides being mounted on the bed each operated by one of the cams, one of the slides being connected to its cam by a cam follower and an elongated link which is disposed entirely beneath the bed. The machine has four slides 12, 14, 16, 18 mounted on the bed 10. The slides 12, 14, 16 are operated respectively by cams 24, 26, 28 secured to shafts 32, 34, 36 arranged along the sides of the bed and connected by bevel gears 40. The shaft 36 carries a drive pinion 42. The fourth slide 18 is connected to its cam 30 by the mechanism shown in Fig. 2. A roller follower 50 is mounted on a lever 54 which is pivoted to the bed at 58 and is connected at its lower end to a link 56, which is also connected to one arm of a bell-crank 62. The other arm of the bell-crank is connected to a short link 66 which is pivotally attached to the centre joint of a toggle 70 comprising the two links 72, 74. The link 72 is pivoted to an abutment 76 and the link 74 is pivoted to the slide 18. The toggle mechanism provides a decrease in the speed of the slide 18 and an increase in the mechanical advantage as the slide nears the end of its travel, which is an advantage in operations such as coining. The positioning of the driving linkage for the slide 18 under the bed leaves the area between the cam 30 and the slide 18 clear for the installation of auxiliary equipment for piercing or punching operations on the metal wire or ribbon workpiece.
