Title: Milk spray dryer exhaust fines recovery - by washing in milk which is de-foamed before recycling to evaporator
Inventor: HELMIG REINHOLD
IPC: A23C1/00
Filed: 1974-12-17
Abstract: Process and paint installation for the recovery of airborne fines of dried milk powder or similar product is claimed of the type in which fresh milk is first evaporated and then passed through a hot air dryer, e.g. spray dryer, from which exhaust air carries fines which are recovered by taking the air through a washer in which the washing liq. is fresh milk, this milk, enriched with fines, is added back to the fresh milk supply prior to the evaporation stage. Essentially, the enriched milk from the washer is collected in a tank and the flaoting foam layer on top of the liquid is sepd. off and passed through a gear pump, homogeniser, baffle box or other means of destroying the foam by mechanical shearing action, residual foamless liq. being returned to the tank ready for adding back to the fresh milk supply. Pref. the fresh milk used as washing liq. is used at 4 to 10 degrees C.

Title: Tickicidal thiazolidine deriv - is 2-(4-chloro-2-methylphenylimino)-3-methylthiazolidine hemihydrate
Inventor: BEHNER OTTO DR
IPC: C07D277/20
Filed: 1975-03-18
Abstract: Crystalline 2-(4-chloro-2-methylphenylimino)-3-methylthiazolidine (I) hemihydrate is new. Also new are animal dips contg. crystals of (I) hemihydrate, and agents against mange mites and ticks contg. crystalline (I) hemihydrate. Crystalline (I) hemihydrate is produced by adding (I) or (I)-contg. formulations to water. Anhydrous (I) is a known oily substance with tickicidal activity. (I) hemihydrate is crystalline and is more readily converted into formulations such as wettable powders and suspension concentrates than is the anhydrous compound. A particular advantage of crystalline (I) hemihydrate is that animal dips contg. suspended crystals of the hemihydrate are not subject to a "stripping effect" (i.e. the crystals of active substance and the suspending fluid are removed from the dip by the animals at the same rate, so that the dip can be replenished with further suspension having the same concentration as the original dip.

Title: Harvested crops density measuring circuit - has generator with electroacoustic transducers, filter and display
Inventor: HERBERTZ JOACHIM DR ING
IPC: A01D41/127
Filed: 1975-07-19
Abstract: The electronic signal-generator continually produces a signal in the frequency range of 10 to 50 kHz. An electro-acoustic transducer continually reflects the signal produced by the generator into the measuring-section containing the crop. An electro-acoustic transducer receives the sound waves which have passed through the crop in the measuring-section and converts them into electric signals. An electronic filter circuit allows through only those signals with frequencies close to the frequency of the signal introduced to the filter circuit. An electronic amplitude measuring-circuit forms a voltage proportional to the amplitude of that part of the signal allowed through by the filter circuit. An indicator, regulator or calculator receives the output signal.

Abstract: The novelty is the compsn. by wt. 4-8% Al, 8-11% Si, 0.01-1.0% of a rare-earth element and/or phosphorus, the remainder being iron. The pref. alloy contains 0.05-0 5% rare earth element and/or 0.05-0.5% P, possibly with 0.01-3.5%, esp. 0.02-2.5% Ti, Zr, Nb, Ta, Mo, Cr, V, W and/or Mn. Numerous esp. pref. alloys are listed, including (a) 4-8% Al, 8-11% Si, 0.05-0.5% rare earth element, 0.1-1.5% Ti, balance iron; and (b) 4-8% Al, 8-11% Si, 0.05-0.5% rare earth element, 0.05-1.0% Ti, 0.05-1.0% V, where Ti + V = 0.1-1.5%, balance Fe. Compsn. is an excellent material for magnetic recording heads. The invention reduces the grain size of te Fe-Si-Al alloys (i.e. the Sendust alloys) so they can be machined without chipping or splintering. The other alloying elements also increase the hardness and wear-resistance.

Title: Multistage pressing cutter for stacked paper - has successively wider cutters and removal channels for single cutting stroke
Inventor: BANSBACH HERMANN
IPC: B26F1/44
Filed: 1975-10-02
Abstract: The pressing cutter is used for making small rectangular or wedge-shaped cuts into stacked sheet or film material. Each cutter has two cutting edges, and only one cutting operation is necessary. Materials cut include deep stacks of paper, cardboard and film. The cutter assembly consists of hollow cutters with a succession of cutting edges (8, 9, 10). These cutting edges are spaced laterally within the same assembly behind each other, so that the cutter with the narrowest spacing between the cutting edges contacts the stack first. Each subsequent cutter is spaced more widely. The minimum clearance between the cutting edges (9, 10) of the cutters (2, 3) and the adjacent cutter bodies (1, 2) ensures removal of the cut material. The throat formed between cutters is sufficient for the removal of cut material which is compressed by the inner cutter flanks and minimum gap.

Both sides of the lock mechanism are gripped by bearing plates (9, 10). The edge slots are generally in the form of U-channel cutouts. Rotating lock components turn around in small bushes situated in the plate members. The side plates are fixed to the door frame by small screws. At right angles to the lock compartment is a flat surface plate with a spigot and a wedge-shaped retaining member.

Title: Control circuit for variable speed DC motor - has speed reference and motor power supply linked to two SCRs and frequency control
Inventor: BRATENGEIER HORST
IPC: H02P7/288
Filed: 1976-06-23
Abstract: If a constant voltage supply is employed for wide speed range motors with transistor control then the power lost in the transistors at low speeds can appreciable and require the addition of forced cooling. This disadvantage may be overcome by having a variable semiconductor element (16) in the power supply (15, 19) in addition to the semiconductors (11a) used for setting the motor (10) speed accurately. By linking both semiconductors to the reference signal (13) the power supply voltage can be matched to that of the load. The main transistors (11a) can then operates with low losses at all speeds and forced cooling dispensed with. The power supply regulator (16) is typically a phase controlled thyristor.
