Patent DE-2521598-A1 (DE)
Title: Cutting of extruded pasta material - into short lengths prior to baking
Inventor: HULTSCH CHRISTOPH
IPC: A21C11/10
Filed: 1975-05-15
Abstract: A machine for cutting to length continuous strips of dough (pasta) esp. Pretzel sticks carried on a conveyor, consists of a cutting edge mounted transversely over the conveyor and movable against it. According to the novelty, the cutting edge is in the form of part of a weighing beam connected via at least one eccentric to a rotatable eccentric shaft on a carrier. A follower located at the other end of the beam works in conjunction with a rotating cam. Two opposing supports are located under the conveyor at a distance from one another and in the region against which the cutting edge bears. The machine is safer, since the cutting edge can be of blunt plastic material and is subjected only to its own weight. In addition, the "cutting" is in effect a squashing action which leaves tapered ends which are more easily wetted by the salt liquor. The "squashing" effect combined with the distortion of the conveyor result in a large enough gap between pieces to prevent them rejoining in the subsequent baking process.

Title: Wound wire end freeing system - temporarily reduces speed of leading end grip in relation to spool
Inventor: EKHOLM RALF CHRISTIAN
IPC: B65H54/34
Filed: 1975-07-03
Abstract: The system leaves a free wire end when winding onto a spool, the forward end of the wire being secured in a grip rotating with the spool during the winding operation. The rotational speed of the grip (8) in relation to that of the spool (3) is temporarily reduced on starting winding, so that the wire end engaging with it comes free of the spool drum (4), forming an arc between it and the grip. speed reduction can be made after winding of the second layer of wire on the drum has started, but before it has finished. Where the winding machine has a coaxial changeover flange rotating with the drum and equipped with a grip for the wire during the changeover, this flange can be in two parts, the one with the grip being slowed down in relation to the frame flange part rotating with the spool.

Title: Rotary piston compressor with two meshing rotors - embodying special cooling arrangements to even out temperatures
IPC: F01C21/06
Filed: 1975-07-14
Abstract: Rotary piston machine has a cage-type rotor (6) and a second, eccentrically located, lobed rotor (7) meshing with the spaces (9) in the first. Both rotate in the space between an outer (1) and an inner (2) casing, fixed to one another in such a way that the lobed rotor causes cyclic variation of thevolume of the chambers formed between rotors and casings. Through openings (4, 5) in the outer casing, gas is thus drawn into the chamber, compressed and expelled again. The inner casing is hollow (13) or at least partially so, and at the ends has inlets/outlets for coolant; coolant distribution is arranged so as to minimise temperature variations within the machine. For additional cooling, the outer casing is finned (12); it may also contain coolant passages connected to those in the inner casing.

Title: Non return mains water valve for washing machine - is operated by screw spindle with spring acting on valve plate
Inventor: SCHOLZEN HERIBERT
IPC: F16K15/18
Filed: 1975-08-21
Abstract: The non return valve (1) for supplying washing machines with water, is operated by a screw type valve spindle (17). The internal end of the spindle locates a compression spring (24) which forces the valve plate (9) against the valve seat (8). The valve can be installed in line with the water pipe, so that most of the valve body is below the wall surface (26). When the valve spindle (17) is screwed outwards, the spring pressure on the valve plate (9) is reduced and the water pressure is able to force the valve open. If the valve outlet pressure is above the inlet water pressure, the valve plate is pressed against the seat (8) thus a return flow of water is prevented.

Title: Foamed building materials - produced by mixing gypsum, anhydrite or cement into stable aq. foam
Inventor: KYRI HANS DR
IPC: C04B28/02
Filed: 1975-10-31
Abstract: Solid-foam bodies are produced by mixing a hydraulically setting material (gypsum, anhydrite or cement) to an aq. foam prepd. by introducing air into an aq. soln. contg. 0.1-1 wt. % of a foaming surfactant, 0.1-1 wt. % of a water soluble aluminium salt and 0.3-2 wt. % of K2SO4. Lightweight structural materials, esp. laminates, are produced at a relatively low cost. The hydration promoters for CaSO4, CaSO4 x 0.5 H2O or cement, and also other additives can be introduced into the soln., to be foamed; this greatly facilitates the process. The foam is stable (in spite of the presence of aluminium salts) because of the addition of K2SO4, which unexpectedly acts as a stabiliser so that the foam is not destroyed by the addition of the solids.

Title: Luminescent diode operation as constant light source - uses conversion of dissipated diode light into electric control magnitude
Inventor: RUMMEL WERNER DIPL PHYS
IPC: H05B44/00
Filed: 1976-04-13
Abstract: The luminous output of the luminescent diode, operated at a constant light source, is held constant by electric control. The dissipated light, impinging at a constant spatial angle from the diode, is received and converted into an electric control magnitude, changing inversely with the luminous output. The control magnitude regulates the operating current of the luminescent diode. Preferably a current analogous to the control magnitude is super-imposed with an independent base current, and the luminous output of the diode is adjusted by changes in the base current. Alternately a base voltage may be used in the same manner. An opto-electronic receiver is used for this purpose, i.e. a phototransistor, or a photodiode.

Title: Edible ice gasified homogenised then deep-frozen - esp. by gas atomising into freezer drum to produce fine structure
Inventor: BONU BONU DIPL ING
IPC: A23G9/20
Filed: 1976-08-04
Abstract: Prodn. of ice-cream by homogenising and then deep-freezing the edible mixt. comprises introducing a gas or gas mixt. into the edible mixt. before the homogenisation stage. Pref. the mixt. is then sprayed into the deep-freeze zone by means of a futher gas or gas mixt. esp. at -30 to -100 degrees C. For both stages CO2 andOor N2 may be used for the gas or gas mixtures. Due to the blowing of gas into the initial mixt. a very finely divided micro-crystalline structure is produced, which considerably shortens the subsequent freezing and hardening times. The use of gas additionally to blow the mixt. into the deep-freezing zone prevents the formation of coarser crystals at that stage.
