Title: Camera film magazine having reduced size image format - has auxiliary gear wheel reducing amount of film transport
Inventor: FRANZMANN RAINER
IPC: G03B17/26
Filed: 1974-09-10
Abstract: In an addition to 2362862 a film magazine for a roll film camera has the aperture of the image window reduced in the film travel direction to form a square picture format or rectangular picture format and the film magazine has a mechanical auxiliary drive to transport the film which reduces the transport distance moved by the film when a non standard format is used. The number of exposures in the non standard format is also counted and displayed. The auxiliary drive device (2) is a single gear wheel, the angle of rotation of which is reduced by the transport sleeve (3) when a reduced size image format is used.

Title: Press for symmetrical dished boiler ends - has digital display unit which is connected to measuring carriage with roller in contact with rim
Inventor: ZEUGIN HANS
IPC: G01B7/02
Filed: 1974-09-24
Abstract: The press is used for making axially and rotationally symmetrical workpieces, especially dished and rimmed ends of boilers, and has a support and clamp for holding the workpiece so that it can be rotated. This pressing machine has a measuring device for measuring the diameter of the workpieces which is connected to the digital display of the measured value. This arrangement ensures that a dished end of a boiler is made to the required specification and matches with other boiler components. The measuring arrangement has a carriage (14) which is guided radially relative to the clamping axis (10). The carriage has a measuring wheel (28a) whose axis of rotation (28b) is parallel to the clamping axis (10). This measuring wheel is brought into contact with the workpiece outside circumference and the display unit (35) is connected to the pulse generator (28) by a cable.

Title: Continuous flow heater for domestic coffee making machine - has circular water pipe under base plate
Inventor: RADER ARMIN ING GRAD
IPC: F24H1/10
Filed: 1974-11-22
Abstract: The circular water pipe is heated by a tubular heater. The water pipe (1) is bent at each of its ends, with a hole at each bend through which the heater (7) passes and runs inside the water pipe (1). Heater terminals (8) project from the holes, and the heater is tightly soldered to the water pipe (1). The base plate (10) serves not only as a support for the water pipe but also as a stand and heat retaining plate for the coffee jug or machine. This construction offers high efficiency since the heater in the water pipe is, for the most part, directly surrounded by the water to be heated.
Patent DE-2460031-A1 (DE)
Title: Thermoplastic yarn false twisting process - uses a conical rotary false twister with constant path of yarn travel
Inventor: GEHRING RUDOLF
IPC: D02G1/08
Filed: 1974-12-19
Abstract: The system to apply a false twisting process to a thermoplastic yarn, by friction contact with the surface of a rotary unit, uses a conical rotary unit where the yarn passes at least 180 degrees round it, where the angle of yarn passage, initially round the rotary unit is equal to half the acute angle of yarn entry to the unit. The conical shape of the rotary unit and the angular control of the yarn passage ensures that it follows a constant course, with consistent friction, giving a consistently texturised yarn.

Patent DE-2519623-A1 (DE)
Title: Continuous flow electrical water heater - has conducting plastic heating element which exhibits sudden change in resistance at specified temp.
Inventor: KALISCHER PETER CHRISTIAN DIPL
IPC: H05B3/82
Filed: 1975-05-02
Abstract: The continuous flow electrical water heater utilises heating elements that experience a sudden change in electrical resistance at a specific temperature. The effect allows the temperature of the fluid to be maintained constant with non-steady flow conditions. The flow tube (1) has a series of annular heater elements (3) along its length. Two conductors (4, 5) supply power to the heating elements, which are manufactured from a graphite filled plastic, the electrical resistance of which depends upon the graphite particle packing density. Secion of the material to exhibit a large coefficient of linear expansion ensures that, as temperature increases, the particle separation decreases and the electrical resistance increases. At a certain temperature the resistance increases suddenly and the heater power falls to an extremely low value to maintain the temperature constant.

Title: Spark gap of overvoltage arrester - is controlled by voltage sensitive resistors in series with spark gap stacks and parallel switching spark gap
Inventor: HERRMANN HELMUT ING GRAD
IPC: H01T4/20
Filed: 1975-10-24
Abstract: The spark-gap of an overvoltage arrestor is controlled by voltage dependent resistors in series with two spark gap stacks. Their exponents of the control resistors in parallel with individual spark gap stacks are different. (The break down voltage of the gap after sparking is an exponential function of the time since the spark). The control resistor (R1) with the smaller exponent is in parallel with a linear resistor (R3) in series with a switching spark gap (F3). Resistors (R1, R2) are such that at extinction voltage, the voltage across the resistor with smaller exponent is greater than across the resistor with larger exponent. The switching spark gap (F3) is separate from the main spark gaps.

Title: Friction minimisation system for fluids in pipelines - has layer of gas generated by vaporisation of part of fluid flowing in pipe
Inventor: SCHMITZ GERD DIPL PHYS
IPC: F15D1/06
Filed: 1975-11-28
Abstract: The friction developed as a result of the flow of a liquid through a tube or pipeline system is minimized. Contact of the fluid medium with the walls of the tube or pipeline section is prevented by the presence of a gas layer between the tube wall and the fluid passing down the tube. The gas layer may be produced by the vaporisation and transformation to gaseous state of some of the fluid passing down the tube. The system can be used for waterpipes, where flow is fast enough for laminar., flow so that only the boundary layer is converted to steam when the pipe exterior is heated.

Title: Electronic control for vehicle air conditioning - with integrated circuits and temp. controlled potential dividers linked to logic switching gates
Inventor: HANSEN HERBERT
IPC: B60H1/00
Filed: 1975-12-01
Abstract: The air conditioning system for the vehicle has a controlled output heater and a non controlled chiller, which is switched on fully when required. The temp. inside the vehicle is monitored by a thermal resistance in a potential divider chain, and with the other resistances variable to set the required level. The chain is linked to a second resistor chain with the mid point of both chains linked to a zero voltage switch. The greater part of the control circuit is part of an integrated circuit chip linked to switching logic gates. This provides a simple, compact control which can be fitted to any air conditioning system. A variety of output signal shapes are available to suit many types of circuit.

Title: Pulse frequency multiplier with two extra delay lines - has two NAND=gates controlling stop:start by breaking main delays feedback
Inventor: RASCH RUDOLF
IPC: H03B19/00
Filed: 1976-08-17
Abstract: The pulse frequency multiplier has a delay line with feedback which is restarted afresh for each input pulse train period and stopped after a given number, n, of pulses by opening the feedback loop. Two extra delay elements and two series NAND-gates are coupled into the feedback loop. This extra circuit blocks the feedback loop at the start of each period T for a min. time equal to T/n. A pulse derived from the edges of the input pulses is allowed after a delay of T/2n to reach the output of the delay line (without feedback) to act as the first pulses of the output sequence. This derived pulse also passes to the input. Only then does pulse multiplication continue.

IPC: C21B9/00
Filed: 1976-09-27
Abstract: A gp. of four regenerative blast heaters are alternately operated for a blast furnace, where one heater(a) is driven at full blast during the middle of the blow, and another (b) is driven in a choked condition at the beginning or end of the blast. The amt. of hot gas for reheating heater(a) is computed by continuous monitoring of total heat removal (QG) from the gp., via. the total vol. (VKWG), temp.
