Title: Wire-tinning systems
IPC: C23C2/38
Filed: 1974-01-17
Abstract: 1443833 Wire tinning system SIEMENS AG 17 Jan 1974 [29 March 1973] 02324/74 Heading C7F The uniformity of coating in a wire tinning system is controlled by placing the wire in tension during the tinning process, coating thickness being determined by wire speed and melt temperature. In a wire tinning system, wire 2 is drawn from a feed reel 1 over rollers 8 in to a degreaser 4, rinsed 5, flushed 7 and further rinsed 5' and passed into a flux bath 11 over a secondary driven roller 9. The fluxed wire is then passed over rollers 12, 12' downwards into a heated tinning bath 13, over an immersed guide roller 16 and pulled upwards out of the bath through an adjustable wire centring device 33 and protective chamber 28 by main roller 17 driven by an adjustable speed motor 18 prior to reeling on a driven take-up reel 32. The main roller 17 is driven at a predetermined slightly higher speed than the secondary roller 9 so that wire 2 is always in tension during its passage through tinning bath 13, and the outlet "cone" 26, within the protective chamber 28 remains constant to maintain uniformity of coating. The coating thickness is controlled by wire speed through the system and by bath 13 temperature. The protective chamber 28 is supplied with a flux i.e zinc chloride, to lower the surface tension of the tinning material and reduce oxidation, and intermediate between guide 16 and main roller 17 are a pair of rollers 37, 38 together with a 'floating' roller 19 which is electrically connected to motor 18 and compensates for variations in pre-set wire tensions.

Title: Improvements relating to liquid cooling systems for internal combustion engines
IPC: F01P7/16
Filed: 1951-02-05
Abstract: 696,085. Engine cooling systems; heating vehicles. DAIMLER-BENZ AKT.-GES. Feb. 5, 1951 [Feb. 4, 1950], No. 2742/51. Classes 64 (ii) and 64 (iii) Relates to liquid cooling systems for internal combustion engines having the normal radiator, a by-pass short-circuiting the radiator, and in addition a heating device which takes up heat from the engine coolant and gives up such heat for example to warm the interior of the vehicle. According to the invention, temperature regulating means is provided comprising a single thermostatic control device whereby the heating device together with the radiator is cut off from the cooling-liquid circuit when the engine is cold, and with rising temperature of the engine coolant liquid, this liquid is first admitted to the heating device and only thereafter to the radiator. In the form shown, the control device comprises a hollow slide valve g actuated by a thermostat c. Fig. 1 shows the position of the valve when the engine is cold. Engine coolant enters the valve chamber b through the passage a and flows through the tubular valve g to the chamber b2 and thence to the by-pass f for return to the engine. In this position the passages d, e, leading respectively to the heating device and radiator are closed by the slide valve g. On a rise in temperature of the engine coolant the thermostat c commences to lift the valve g and hot coolant fluid from the engine is allowed to flow through the passage d to the heating device (e.g. vehicle heater). On a further rise in the temperature of the engine coolant the valve opens the passage e allowing some of the coolant to flow to the vehicle radiator, and at the same time the by-pass f is closed. In alternative arrangements, the by-pass f may be closed when the passage d to the heating device is opened or by the by-pass f may be wholly or partially closed when the engine is cold, so that little or no circulation of coolant can take place until the engine has warmed up. A poppet type valve may be used instead of the slide valve shown.
