Title: Thick film resistor produced by oxidizing reducing - and fritting a metal on a substrate
Inventor: MARIE GUIOT JEAN
IPC: H01C17/065
Filed: 1969-05-14
Abstract: Thick film resistor produced by oxidising reducing and fritting a metal on a substrate. G6A. Before fritting, the layer receives an oxidic compound of a substance with a higher stable state of oxidation so that at least a part of it is converted into a higher oxide and some of the oxygen released by the reduction of the metal oxide is fixed. Both the oxidic compound and the higher oxide is compatible with the vitreous body formed by fritting. The substance contains arsenic, antimony or bismuth and has a trivalent and a pentavalent oxidation state. If it contains As2O3, the fritting temperature is 720 degrees C. Enough As2O3 is added to retain in the fritted element 0.6-1.4 wt.% of arsenic compounds. The metal may be palladium and the reducing material silver.

Patent DE-2119160-A1 (DE)
Title: Steam peeling plant - for fruit and vegetables with partial vacuum step
IPC: A23N7/01
Filed: 1971-04-20
Abstract: The steam chamber with gate valves at top and bottom through which it is loaded and unloaded, is subdivided into three compartments by intermediate gate valves so that the plant can be run continuously with the compartments joined in pairs. A steam valve allows HP steam at esp. 0.5-8 kp/cm2 to be fed to the centre compartment for flash heating for 50-50 secs. respectively and the top and bottom chambers via rapid acting valves to a vacuum chamber which allows the pressure to be dropped below atmos. after the flash steaming which further assists stripping of only a minimum thickness cooked layer and hence reduces waste.

Title: Moulded plastic book bindings - made by injection moulding
Inventor: TERRELL CHRISTOPHER E
IPC: B29C45/56
Filed: 1971-10-25
Abstract: In a process for fabricating a plastic article having two portions joined by a core or membrane of the same material, the article is injection moulded and the plastic material compressed in the neighbourhood of the core or membrane required at the time when the material is still in the mould. The difficulties of moulding such articles are overcome by compressing the membrane section to the required thickness after preforming in the mould. The core or membrane is compressed to shape by introducing a plate or sheet which enters the mould after injection and complete filling of the mould. The tool may be mounted on shafts operated by springs, the punch having an alternating motion.

Title: Plate press - esp for chipboard has reduced pressure jump at transition to pressurised air chamber
Inventor: KERTTULA INTO
IPC: B30B5/04
Filed: 1973-04-10
Abstract: A continuously operating plate press, comprises moving surfaces, >=1 of which is an endless belt running along the open side of a pressurised air chamber; this belt is of magnetisable material and the inlet and outlet edges of the pressurised chamber, over which the belt runs, are fitted with >=1 magnet esp. electromagnets with variable attractive force. The pull of these magnets upon the belt is thus opposite to the pressure exerted by the air in the chamber. The action of the magnet at inlet and outlet of the pressurised chamber reduces the pressure drop and thus reduces wear on the belt.

Title: Potassium acid tartrate removal - from wine by reverse osmosis and filtering of tartrate crystals from concentrate
Inventor: RHEIN OTTO H
IPC: C12H1/02
Filed: 1973-09-28
Abstract: Potassium acid tartrate is removed from wine or champagne by reverse osmosis through a semipermeable membrane. The soln. is divided temporarily into permeate and concentrate, so that the potassium acid tartrate excess can be sepd. spontaneously from the conc. by natural means. When the crystals have been removed, the permeate and concn. care re-combined. This eliminates the legally disputed use of cation-exchangers for the purpose of removing the tartrate crystals. In organoleptic respect, wine thus treated is pref. to that treated by freezing or electrodialysis. The process is also less expensive.

Title: Filter with reversible pump for water purificn. systems - using container which ensures backwashing speed just sufficient for cleaning
Inventor: BOERNER HANS
IPC: B01D24/12
Filed: 1974-03-13
Abstract: The container holding granular matl. for the filter bed of a water purificn. system, fitted, together with a reversible pump for washing out as required, in a section of the piping layout, and having at one side a feed water inlet and a swill water outlet, has in the section closest to the swill water outlet, a greater sectional area than in the zone of the pure water outlet. The dimensions of the two container zones are determined so that the prescribed relatively high filtration speed is reduced to the optimal swilling out speed by the widening of the upper section of the container. Device makes a choke or redn. of the pump output unnecessary.
