Patent DE-2737776-A1 (DE)
Title: Sheet material wrapping mechanism - has rollers working with cutter to join sheet edges together
IPC: B65H19/18
Filed: 1977-08-22
Abstract: The sheet material application mechanism is for a wrapping machine and has two storage rolls and two pressure rollers movable w.r.t. each other. Guide rollers deliver the sheet from one or the other roll past the pressure rollers to a point where the paths of the sheets from the two rolls join. A cutter parts off one or the other of the sheets from the roll on an external command. A control unit operating in synchronism with the cutter moves one pressure roller towards the other pressing the leading edge of the new sheet against the trailing edge of the old sheet.

IPC: C13K1/02
Filed: 1977-09-30
Abstract: In the continuous hydrolysis of vegetable matter with dil. acid at high temps., e.g. to produce xylose and sugars, the dearated matter descends in a vertical reactor in counterflow to the acid. Hydrolysis and extraction is followed by scrubbing in counterflow with hot water and by continuous discharge from the reactor. The system combines the max. sugar yield with the min. acid consumption. It is suitable for prehydrolysis (hemicellulose) as well as for hydrolysis proper. Only simple proven process techniques are applied.

Title: Moving staircase transition curve - has involute or approximate involute form to give shortest travel without excessive acceleration
Inventor: BAUMANN JOACHIM ING GRAD
IPC: B66B23/14
Filed: 1977-11-04
Abstract: The path of an escalator or moving staircase includes a sloping part where the treads follow a transition curve intended to give the shortest length without undue discomfort to the usters. Thus curve is preferably an involute curve, with the over-all angle of slope divided up into short sections, each with its own radius of curvature. An alternative curve may be used, approximating to an involute curve, giving the same horizontal acceleration to the user. When the slop is too great, the acceleration is excessive.

Title: Cheese prodn. - using ultrafiltration permeate for acidification after cation removal, of the milk
Inventor: KUIPERS ARIEM REITMEHRING
IPC: A23C19/028
Filed: 1978-05-29
Abstract: Prodn. of cheese comprises ultrafiltration of milk, of reduced pH to give a retentate which, opt. after adding other milk components such as cream, is thickened or coagulated, then processed conventionally to cheese. Novelty is that the permeate from ultrafiltration is acidified by cation removal (pref. to pH 1-2) and then used for reducing pH of the milk. Pref. the milk is acidified to between pH 6 and the coagulation point of casein. Opt. only a portion of the permeate is acidified, then added to untreated permeate to give the required final pH. Ultrafiltration is pref. controlled to give vol. ratio permeate:retentate of 1.5-3:1. Process does not require additional, non-milk acids or fermentative pre-ripening. It is easily controlled to give the required characteristics (taste and consistency) of a wide range of cheese types. Both the milk used for cheese making and the permeate may be used in conc. form. Acidification is esp. by treatment with a cation exchanger or by electrodialysis.

Title: IC engine spark plug - has integrated ignition coil secondary embedded in spark plug insulator
Inventor: THIEL KARL
IPC: H01T13/44
Filed: 1978-09-02
Abstract: The secondary coil of the ignition transformer is embedded in the insulator of the spark plug, while the primary for high voltage induction is mounted outside and round the spark plug insulator. This arrangement prevents attenuation of the high voltage plus, when conducted via a cable, due to capacitance and inductances, which would limit the pulse flank steepness. The arrangement also removes limits for increasing flash over voltages necessary for moist and dust polluted air.

Filed: 1978-10-21
Abstract: The metering system, for pumpable feedstuffs, has a mixing vessel, a pump, a metering vessel and conveying tube that passes the mixed, metered feedstuff to the place where the animal usually eats. The conveying pump sucks the feedstuff from the metering vessel and passes it to the eating places via the conveying tube. Non-return valves control the flow of feedstuff depending on the direction of the pump. The volume of the metering vessel is equal to the max. quantity of feedstuff required at an eating place. A limit switch in the upper region of the metering vessel controls the degree of filling of the same. An indicator is located in the region of the eating place and indicates the quantity metered into the metering vessel.
