Patent DE-3151890-A1 (DE)
Title: Sandbag-filling device
Inventor: LENKEIT RUDI
IPC: B65G65/48
Filed: 1981-12-30
Abstract: The device is concerned with the metering and filling of bulk materials, in particular of sand into bags, as are required, inter alia, for emergency defence purposes. This involves using a simple and reliable device which is not dependent on outside energy for the uniform filling of a large number of bags in situ in a short time. For this purpose, a cellular sluice is used which is arranged between a filling hopper and a discharge hopper. By turning the outer handwheel connected to the vane wheel in the cellular sluice, the upper and lower chambers open, allowing the bulk material to flow in and out. The device makes it readily possible for 600-700 sandbags per hour to be filled with the same amount of material.

Filed: 1982-01-12
Abstract: The invention relates to a turbine with an elliptical casing and a rotor, in the gaps of which vanes are mounted. A machine of this kind is suitable both as a rotary pump and as a turbine. The invention sets itself the object of providing a turbine or pump in which the vanes are in contact with the elliptical casing. This object is achieved by virtue of the fact that the contact of the vanes with the inner surfaces of the casing can be adjusted by means of the lugs of the vanes and by means of the elliptical grooves in the housing cover, each vane thus having two lugs and there being an elliptical groove in each housing cover. The lugs of the vanes fit into the grooves of the housing cover, with the result that the vanes are in continuous contact with the elliptical casing.
Patent DE-3207048-A1 (DE)
Title: Digester for the fermentation of cellulose materials and for the production of methane
Inventor: AUBERTIER MAURICE
IPC: C12M1/107
Filed: 1982-02-26
Abstract: In a digester for obtaining methane from cellulose waste, for energy-saving temperature control for optimal anaerobic fermentation, fermentation liquid, such as farm slurry, in a collecting chamber under a perforated intermediate floor carrying the cellulose waste is heated by supplying heat from outside. The heated fermentation liquid is transported vertically upwards and delivered, uniformly distributed, onto the cellulose waste. The fermentation liquid then runs downwards under the influence of gravity within the cellulose waste into the collecting chamber, which makes it possible to keep the temperature of the cellulose waste in the very narrow optimal fermentation range. A vertical central pipe is provided in the digester and extends from the collecting chamber through the intermediate floor and through the cellulose waste via an upper grid and terminates in a syphon. A free upwards-directed convection current of the fermentation liquid is set up in the pipe. The pipe can also be passed, with interpolation of a pump bringing about a forced convection current, outside the digester from the collecting chamber via the upper grid. The activation of the pump can be controlled by a temperature sensor located in the cellulose waste. <IMAGE>

Patent DE-3219663-A1 (DE)
Title: Process for detecting breakdowns in an electrostatic filter
Inventor: NEULINGER FRANZ DIPL ING
IPC: B03C3/68
Filed: 1982-05-26
Abstract: For regulation of an electrostatic filter which is supplied from an alternating current mains via a rectifier, a high voltage transformer and a regulating unit, the process compares a voltage value with a reference value and uses deviations from the reference value to control the voltage regulating means. The voltage difference between two successive measurements is used as the voltage value, and the voltage difference between the two preceding measurements is used as the reference value. The difference of the absolute values of the two voltage differences is ascertained and is compared with a value X which determines the sensitivity of response. Further, an undistorted reference curve with a grid  DELTA U = constant is analysed and a time grid with  DELTA t  NOTEQUAL  constant is thus derived, according to which the measurement program then proceeds. With a course of voltage without breakdown, all voltage differences are equal under this condition, i.e. the value x can be chosen theoretically as zero, practically as very small.

Title: Circuit arrangement for operation of an optical transmitter
Inventor: BAMBACH WOLFGANG DIPL ING
IPC: H04B10/50
Filed: 1982-08-28
Abstract: The invention relates to circuit arrangement for operation of an optical transmitter in an integrated-services broadband transmission system with devices for the transmission of narrowband and broadband signals between subscribers and an exchange via an optical waveguide system, with a biasing current feed-in device controlled by a control amplifier and a driver amplifier to amplify the narrowband signals, where the devices required for broadband operation can be de-activated to operate the optical transmitter for narrowband-only operation. According to the invention, the modulation of the driver current for the optical transmitter is carried out through modulation of the biasing current by means of the output power of the narrowband driver amplifier. The modulation of the biasing current is initiated in inexpensive fashion via a coupling capacitor at the base of the current source transistor, at the base of which the output of the control amplifier is also connected via a protective resistor. <IMAGE>

Title: Portable electric jig-saw with guide plate
Inventor: GEBAUER KARL
IPC: B25H3/00
Filed: 1982-10-12
Abstract: Due to the saw blade projecting far out of the housing of a jig-saw and due to its hammer shape, a jig-saw cannot be placed in a certain position but can only be put down sideways. The object of the invention is to improve a jig-saw to the effect that it can be placed in a certain position despite its hammer shape and the projecting saw blade. According to the invention, provision is made for the jig-saw to have a standing foot articulated at the guide-plate end remote from the saw blade in such a way that it can be swung downwards. This has the advantage that the jig-saw can be put down in its normal working position and is therefore always ready to hand for an operator.

Patent DE-3310456-A1 (DE)
Title: Belt release
Inventor: VOGEL HEINER
IPC: B60R22/32
Filed: 1983-03-23
Abstract: In most versions of strapping-in belts, to strap a person in, the belt is engaged by means of a pawl on a fixed point attached, as a rule, in the middle of the vehicle. This pawl has to be actuated in order to release the strapping-in belt, the motor-vehicle occupants involved in an accident often being incapable of doing this. But they are also very difficult to reach for rescuers entering from outside, especially when the vehicle is burning. The invention provides an automatic belt release which is characterised in that a separating mechanism (2) responding to the extreme belt tension is inserted between the belt buckle (1) and fixed point. <IMAGE>

Patent DE-3333754-A1 (DE)
Title: Pneumatic bass loudspeaker
Inventor: KREMER HELMUT
IPC: H04R1/28
Filed: 1983-09-19
Abstract: Design principles are used by some loudspeaker manufacturers to utilise the sound energy radiated into the cabinet in order to increase efficiency. These are known as bass reflex, phase inversion or passive loudspeakers. The greatest disadvantage of a partially open cabinet is the radiation of reflections by the bass reflex or phase inversion aperture. Even a passive loudspeaker inverts the phases only to the extent permitted by the pressure conditions in the cabinet. The pneumatic loudspeaker comprises a passive diaphragm to which a phase inversion tunnel is connected. This design principle operates satisfactorily even at low frequencies and does not radiate cabinet reflections. A 20 cm bass loudspeaker at 90 dB radiates the same sound pressure as a 30 cm bass loudspeaker at 100 dB efficiency. The tunnel dimensions are calculated according to the following formula:     Tunnel cross-section = volume in litres: 1.62 = cm<2>   Tunnel length = cross-section in cm<2>: 2 = length in cm.  The basis of this formula is explained in greater detail below. (1): 30 cm bass in enclosed cabinet, 20 cm bass combined with pneumatic bass loudspeaker! <IMAGE>

Abstract: An administrative-control system for a plurality of copiers is described, by means of which the usage conditions for a plurality of copiers can be monitored and administratively controlled in concentrated form. Terminal units are allocated to these copiers in the ratio 1:1. A magnetic card stores information about a specific department which may use a specific copier; this magnetic card is arranged at a predetermined point in the terminal unit, before a copying process is started. Various copier data, which are allocated to use of the copier, are stored in a memory in the terminal unit which is allocated to that copier. The copier data are supplied on demand to a central administration-control unit and are read out from said unit. Each terminal unit can block the use of a specific copier by a specific department if a corresponding instruction is received from the central administration-control unit. In addition, a telephone connection is possible between the central administration-control unit and each terminal unit, via the communication device which is arranged between these units. In consequence, the operating personnel at the central administration-control unit can have voice contact with the operating personnel at the copiers.
