Title: Chemical clothes cleaning machine - has a continuous heater in the distillation vessel
Inventor: CHRISTOF EMIL
IPC: D06F43/08
Filed: 1978-05-12
Abstract: In the distn. stage of a chemical clothes cleaning machine, there is a continuous heater within a vessel. The outlet of the heater opens into the interior of the vessel and its inlet is linked to the pressure side of a pump, its suction side being linked to the distillation vessel. The heater outlet is mounted above the heater, which is partially immersed in the fluid being distilled. There is a water or stream feed passing into the vessel, and there is a further heater in the base of the vessel. The design eliminates the need for a sec. distn. stage, in the recovery of the solvent, even when there is a heavy concn. of dirt to give a continuous action.

Title: Fat contg. milk protein tablets prodn. - from skim milk powder, non-milk fat and sucrose
Inventor: KOHL KURT
IPC: A23C9/18
Filed: 1978-06-07
Abstract: Prodn. of fat-contg. milk protein tablets comprises first processing skim milk powder (A) and non-milk fat in about equal amts. to a fat concentrate. This is then blended with more (A) in about 1:4 ratio, then this mixt. combined with sucrose in about 7:3 ratio and the final mixt. tabletted. Sucrose is pref. used in granulated, crystalline form and the mixt. may include a flavouring. Opt. the non-milk fat is mixed with skim milk to give a fat-in-water emulsion which is dried to give the fat concentrate directly. Only skim milk is needed as protein source, tabletting is easy and tablets have long storage times. Non-milk fats are much more stable (and generally cheaper) than milk fat and also serve as lubricants during tabletting. The sugar minimises caking of (A) during processing.

IPC: H03F1/54
Filed: 1978-08-03
Abstract: The transmitter has an energy store and a DC supply with a second energy store and an ignitable discharge path preventing the energy store discharge through the arc-over distance. Both energy stores can be discharged through a discharge circuit each, with, however, a common discharge path through which the two currents flow in opposite directions with different decay time constants. One passive switch shortens the intermediate time interval between the end of preponderance of the discharge current which maintains the ignited state in the discharge path (E), and the beginning of the DC supply (G) short-circuit current.

Patent DE-2844354-A1 (DE)
Title: Pressure joining of successive copper bars - in continuous rolling mill to improve weld quality
Inventor: VERVLIET RENE
IPC: B23K20/24
Filed: 1978-10-11
Abstract: The ends of two round bars are joined together under pressure. The bars are the prod. of a continuous process for melting copper, pouring it into the form of a bar, cooling the bar and then passing it through rollers to attain the desired cross section. The system for joining successive lengths enables the rolling process to be continuous. The rods. are heated to between the m.pt. of the metal and 200 degrees C below the m.pt. and are then fed into the welding device. The leading end of the new bar and the after end of the continuous bar are cut by shears to wedges, the leading edges which are at right angles to each other. The two ends are then gripped by jaws and pushed together to such an extend that excess metal containing oxide is pushed into a disc shaped die around the weld. As the jaws release the rod, it passes through an orifice with a cutting edge which removes the excess metal. The round bar then continues through the rolls until the next join is to be made. To enable the rolling mill to continue working at a steady speed, there is an expansion loop of metal stock between the welding device and the mill. When the end of the stock is clamped for welding, the slack in the loop is taken up by the mill. After completion of the weld, the new stock is fed into the mill faster then the rolling rate so that the loop is expanded. Only 2 or 3 diameters of each end must be pushed into the weld to achieve the same exlusion free product.
