Patent DE-2350307-A1 (DE)
Title: Sales unit assembly process - feeds cardboard sheet between items and wrapping sheet before welding later
Inventor: NOACK FRITZ
IPC: B65B11/10
Filed: 1973-10-06
Abstract: The process allows sensitive items to be assembled into a stackable unit, the items being fed forward against a sheet inclined to their direction of travel, after which the sheet is looped round them, closed at the rear, pulled tight, welded and parted off. Before the formation of the loop, a piece of cardboard is fed forward into the path of the items and between them and the sheet, so as to be caught between them. Forward movement of the items causes the cardboard to be folded round them, and held in position against them without the use of glue, merely by the closed and welded sheet. The cardboard can be in three or more sections, fed in front of the items through a slot in the table, so as to bring the bottom section below the table and the front section above it.
Patent DE-2355223-A1 (DE)
Title: Non-hierarchical telecommunications network - has method for finding a free connection path between an exchange of origin and a target exchange
Inventor: PLAUE GUENTER
IPC: H04Q3/00
Filed: 1973-11-05
Abstract: The target exchange is given by the called subscriber address. Starting from the exchange of origin, the address of the called subscriber is transmitted to intermediate exchanges through data channels parallel to the connection path proper. This address is in the intermediate exchanges compared with subscribers connected to them directly or through a terminal exchange. When the address received from the exchange of origin coincides with the address of a subscriber connected to the intermediate exchange as above, a free connection path is selected and built-up by a mimic store in each of the exchanges from the exchange of origin.
Patent DE-2364621-A1 (DE)
Title: Tape recorder drive mechanism - has capstan motor for constant speed tape transport and take-up motor
Inventor: REESE PETER
IPC: G11B15/54
Filed: 1973-12-24
Abstract: One or more resistors are connected in the circuit of the capstan motor and provide a regulating variable for the control of the torque of the take-up motor. The regulating variable depends on the load of the capstan motor and in particular on the current for maintaining the take-up of the tape at a constant tension. The voltage proportional to the motor current is utilized for controlling the base-to-emitter voltage of a transistor. The output voltage is fed to a further transistor, which acts as a regulating element for the torque of the take-up motor.
Patent DE-2364716-A1 (DE)
Title: Load suspension unit on curved stretches of pit arch - has traverse mounted on section web and carrying suspension eyelet
IPC: E21F17/02
Filed: 1973-12-27
Abstract: The traverse incoporates two holes thorugh which two threaded bolts can be passed and clamped by two nuts. The top ends of the bolts are formed as hooks which engage behind the limb ends of the gallery arch. The traverse can be used with different widths of gallery arch channel sections whose web ends rest in concave side surfaces which can accommodate different widths of web. Once the traverse has been clamped by the bolts to the gallery arch then loads can be hung via, for example a chain and a hook to the eyelet.
Patent DE-2405825-A1 (DE)
Title: Tunnel furnace for agricultural and forestry waste - is charged with batches of fuel and intermittent air supply
Inventor: HAESSLER ANDREAS
IPC: F23G5/44
Filed: 1974-02-07
Abstract: The agricultural and forestry waste is incinerated in a furnace charged at the top. The material hopper and the furnace chamber are separated by a hermetic seal formed by the fuel compacting machine. This ensures that the flame is not able to backfire into the charging hopper which may contain readily combustible waste such as straw and timber waste. The furance chamber and fuel hopper are separated by a compactor so that the fuel can be charged into the furnace together with air and premature ignition is prevented. High temps. are maintained by feeding fuel and air into the furnace in batches.

Title: Heat exchanger for use with helium - has adjacent chambers separated by continuous strip suitably bent and folded
Inventor: FOERSTER SIEGFRIED DR
IPC: F28D9/00
Filed: 1974-02-22
Abstract: The heat exchanger is intended for use with helium in atomic power plant. It consists of longitudinal chambers running parallel to each other, alternate chambers containing the two fluids exchanging heat. The chambers are formed by a thin metal sheet which is bent and folded into a series of longitudinal corrugations to make spaces open alternately to the top and bottom. Upper and lower plates a small distance above and below the corrugated sheet, join the sets of alternate chambers and the enclosure is completed by end plates. Flow and return headers are provided above and below the casing for the two fluids. The construction avoids all possibility of leaks between the two sets of chambers.
Patent DE-2408772-A1 (DE)
Title: Measurement of thickness of oil layers on water - using single impulse from below with sepn. of echoes from the two interfaces
Inventor: BOLZMANN HANS
IPC: G01S15/88
Filed: 1974-02-23
Abstract: Measurement of the oil content of water, using echo-sounding equipment below the surface, is carried out by differentiating the rising flanks of the reflected signal from the oil-water boundary and that from the oil-air boundary, to obtain rectangular-form impulses sepd. by a time interval which is converted into length units and displayed. Process is used for continuous checking of water effluent from cooling coils eg. in oil-cracking plants, to detect contamination by oil. Also for measurement of oil in water ballast of tankers to prevent discharge when emptying. Use of a single emitted impulse to produce two reflected signals gives much greater accuracy than using separate echoes from two spaced impulses.
Patent DE-2409590-A1 (DE)
Title: Boiler heated by an atmospheric gas burner - has separate regulators for main and safety valves in the gas pipe
Inventor: BECKER DIETER
IPC: F24H9/20
Filed: 1974-02-28
Abstract: The boiler with atmospheric gas burners and thermoelectrical ignition safety device has a main gas valve and a safety valve which is regulated by a thermocouple in the ignition flame, this ensures that gas supply to the burner is blocked when the ignition flame has failed. The separate regulation for the main and safety valve ensures that no gas is admitted to the burner in the absence of an igniting flame. An additional thermocouple is provided for the main flame so that the thermocouple of the main flame is short circuited under normal operating conditions. In case of a failure the short circuit is opened and both thermocouples are connected in series which results in a voltage drop in the thermal current circuit and this causes closing of the safety valve. The regulator is situated in the water chamber and a monitoring device is also provided. The gas supply line of the burner has a main valve and additional safety valve which is actuated by a thermocouple placed into the ignition flamfe of the igniter.
