Title: Two-stage concentration of milk products - for subsequent rennet fermentation in cheese prodn
Inventor: LAGUILHARRE PIERRE ROBERT
IPC: A23C19/028
Filed: 1974-05-29
Abstract: The improvement in cheese prodn. by the known technique of rennet fermentation of an enriched fraction from an aq. mother liquor of a milk prod. having a protein content corresp. to that of the water-free cheese, whereby (a) a pre-determined quantity of water is added to an aq. soln. of a milk prod. (S1) to obtain a soln. (S2) with a lower lactose content relative to the total mass of water and lactose and salts, (b) the soln. (S2) is subjected to controlled concn. using an ultrafiltration membrane to produce a residuce (R1) in which the ratio of protein content to lactose content has a desired value (a), (c) the residue (R1) is concd. by any suitable known process e.g. evaporation or freezing, to produce a conc. having a content of protein and lactose corresp. to the desired value of water-free cheese. Because of the reduction of protein content and therefore of viscosity in the ultrafiltration stage e.g. from ca 100 cPs to ca 10 cPs, the total area of costly membrane surface required is much smaller, despite the increased vols. of soln. to be treated. The processing costs are therefore much lower.

Title: Timer for storage heater charging - generates additional control voltage linearly varying from maximum to zero
Inventor: GROSSE-BRAUCKMANN HELMUT DR IN
IPC: F24C7/08
Filed: 1974-06-11
Abstract: The timer uses an additional control voltage which regulates the shift in time of charge beginning during the night low tariff period. This additional control voltage is derived from a high capacitance capacitor voltage, using its nearly linear, initial part of discharge characteristic. The capacitor is a solid state electrolytic capacitor, charged during high tariff period by a voltage divider ensuring its full charge in one or two hours. It is discharged through a changeover contact controlled by a time switch, through a resistance which produces a time constant of approx. three times the low tariff period.

Title: Arc welding using carbon dioxide protective gas - and argon fed round non-consumable electrode in burner
Inventor: SHIMADA WATARU
IPC: B23K9/167
Filed: 1974-12-16
Abstract: The arc welding process uses a non-consumable electrode plus a gas (I) consisting of carbon dioxide or a mixt. of CO2 with oxygen or an inert gas. The novelty is that inert gas (II) is fed through an inert concentric jet (II) surrounding the electrode whereas gas (I) is supplied through an outer concentric jet (I) surrounding jet (II). Instead of an outer concentric jet (I) a number of tubes can be mounted on the outside of the jet (II) for carrying gas (I). A welding rod contg. a deoxidant is pref. used during the process, this rod being fed to the weld between the non-consumable electrode and the seam. One pref. burner for this process uses jets (I) and (II). Method provides a modified carbon dioxide welding process where the electrode is protected and a stable arc is obtd.; welding defects are avoided and the considerable amt. of metal spray normally experienced with CO2 is prevented; this spray has to be periodically removed so long continuous runs are usually impossible.
Patent DE-2459754-A1 (DE)
Title: Electronically commutated brushless multipolar DC machine - with current feed at two positions from separate sources in protected against antiparallel connection
Inventor: SCHADE WALTER DR
IPC: H02K29/00
Filed: 1974-12-18
Abstract: The object is to avoid anti-parallel connection of the switching thyristors in machines with multiple pole pairs thereby eliminating fast rates of change during commutation which may give rise to spurious triggering of the thyristors resulting in short circuits. The object is achieved by connecting the coils of a drum wound armature such that they form series groups per pole and also form the equivalent of a two pole winding as in 2133489. The risk of short circuits is further dimished by splitting each current feed into two sections supplied from separate DC sources, for example rectifiers. Decoupling diodes may be added if the supply rectifiers have a common A.C. feed.

Title: Textile strand fluid treatment - having fluid jets and guide tubes with separate throughs to give a multi-phase continuous process
Inventor: SCHIRM GUENTER
IPC: D06B3/28
Filed: 1974-12-31
Abstract: A continuous wet treatment to textile strand material, such as a washing/bleaching/washing cycle for stiff materials utilises an automatic speed control system. The material passes over a guide roller to the entry of an initial jet assembly. Through the jet fluid flow the material passes through an initial guide tube to be passed more slowly through an initial through filled with fluid. The process is repeated by passing round the guide roller to further jets in success and their filled troughs before passing over a final guide roller to travel to further processing stages. The design allows the combination of a number of fluid treatment processes into a continuous operation.
