Title: Recording roll mechanism with inertia part driven by capstan - has roll support coupled with capstan and operating lever moved by power source
Inventor: ASTE ROBERT
IPC: G03B1/18
Filed: 1979-07-06
Abstract: The mechanism has a part affected by inertia, a capstan, a recording roll with its support, a blocking lever and a device releasing the mechanism movement. An operating lever is moved by a power source controlled by the release device, and by a driving device on the inertia part. The resultant movement is transmitted to the recording roll support spring loaded in the direction towards engagement between the roll and the capstan. The recording roll support is thus moved away from the capstan and can be locked in this position. The power source (1) can be connected at the end of recording and again disconnected by the roll support (6) in its out position.

Title: Accurate determn. of total organic carbon in water - using purge and trap technique with adsorption conversion to methane and monitoring
Inventor: BERNARD BERNIE BOYD PROF
IPC: G01N31/00
Filed: 1980-04-23
Abstract: Total organic carbon present in an aqueous sample is determined by a three stage procedure. Firstly all the inorganic carbon is removed. The volatile carbon compds. are then purged out by an N2 stream which is bubbled through the sample. The organic material removed in this way is adsorbed onto a polymeric adsorbent material. It is subsequently desorbed and converted to CH4, the quantity of which is measured. Non-volatile organic material is determined by heating some of aqueous sample in a H2 atmosphere to convert it to CH4. The quantity of CH4 formed then gives a measure of the total carbon. Used for measurement of total carbon in water streams. The technique of purging is known but some materials are not sufficiently volatile to be removed by the purge. The technique described extends the method to give total carbon.

Title: Accumulator plate sheath - made of polyester fibre mat with over sixty five per-cent porosity in bag shape
Inventor: METZLER OTTO
IPC: H01M2/14
Filed: 1980-05-06
Abstract: The Parent Patent No.2610116 described an electrode plate for accumulators, enclosed in a sheath, consisting of an oxygen-and acid-resistant plastic material with a porosity of at least 65% by fine perforations of up to 0.1 mm diameter. As a perforated plastic foil has not an adequate strength, it is now suggested to use a fibre mat of polyester threads which is made into a pocket by sewing or welding. The fibre mat can have a percentage of glass fibres, and holes of 0.06-0.1 mm dia. give it a minimum porosity of 70-75%. This can be made at low cost and is specially suitable for positive plates which are possibly short-circuited by anode slime.

Patent DE-3019725-A1 (DE)
Inventor: TELLERT RUDI
IPC: F02D31/00
Filed: 1980-05-23
Abstract: The speed-of-revolution controller keeps the speed of revolution of an internal combustion engine, for example of a small motorcycle, at an adjustable set value by means of a drive which acts on a speed-of-revolution adjusting element of the internal combustion engine. A direct current motor (27) which is coupled via a self-locking mechanism to the speed-of-revolution adjusting element is connected to an electric control circuit which determines the speed of revolution by means of an electric speed-of-revolution sensor (1, 5). The control circuit superimposes on a signal which corresponds to the difference between the speed-of-revolution sensor signal and a set value signal a bipolar signal which is produced by a signal generator (13) with a predetermined frequency and at least one sloping edge per period and feeds the superimposed signal to a comparator (19). The comparator outputs driver pulses for a first direction of rotation to the direct current motor (27) if the superimposed signal is greater than a first threshold value. The comparator (19) outputs driver pulses for a second reverse direction of rotation to the direct current motor (27) if the superimposed signal is smaller than a second threshold value. By virtue of these measures, the performance of the internal combustion engine can be limited without a rise in the specific consumption. <IMAGE>

Title: Independent operation of several electric model locomotives - using changes in basic voltage and specified selection of voltage frequency
Inventor: LENZ BERND
IPC: A63H19/24
Filed: 1980-07-02
Abstract: The toy or model locomotive operation uses control siqnal transmission with modulated basic voltage of variable polarity, continuously supplied to the toy train set current leads. The train set locomotives comprise receivers and controllers for the power supply to the traction motors. For operation of locomotives without such receivers and controllers, the DC component of the basic voltage across the current leads is changed without affecting the rectifier value of this voltage. The frequency of the basic voltage is to be selected so high that the voltage alternating component is not sufficient to drive these locomotive traction motors. Thus it does not generate any non-permissible motor heating. When a rectangular voltage is used, the scanning ratio of the rectangular voltage is used for changing the direct component of this basic voltage.
