Title: Circular saw blade and method of producing it
Inventor: ARNTZ WILHELM
IPC: B23D61/02
Filed: 1982-05-03
Abstract: The invention relates to a metal circular saw blade with a saw-blade body, reduced in thickness by at least one annular-disc-shaped recess, and at least one supporting ring sitting fixedly in the annular-disc-shaped recess and riveted to the saw-blade body, the width of the recess being slightly greater than the width of the supporting ring, and the centre point of the recess and of the supporting ring preferably coinciding with the running axis of the circular saw blade, characterised in that the depth of the recess is greater than the thickness of the supporting ring. Furthermore, the invention relates to a method of producing the circular saw blade, in which studs are welded onto the rear side of the supporting ring by means of a template, and the supporting ring is then placed in the recess of the saw-blade body, the studs passing through the holes in the saw-blade body, whereupon the forming of the rivet heads takes place in a manner known per se.

Title: Battery-operated insulation measuring instrument
Inventor: HENNEBERGER HEINZ DIPL ING
IPC: G01R27/02
Filed: 1982-07-14
Abstract: In a battery-operated insulation measuring instrument, comprising a switching stage for generating the measuring voltage, measuring terminals (5) for applying the measuring voltage to a device under test and a switching stage for receiving the measurement value and an indicating stage (10), a fixed first timing stage (6) connected to the battery (2) and switching DC/DC converter (1) used for generating the measuring voltage is provided for considerably increasing the number of measurements with one battery and better utilising the battery charge, a second timing stage (7) triggered by a measuring voltage regulator (3), the second timing stage (7) operating in conjunction with the first timing stage (6) in such a manner that after a time determined by the second timing switch (7) has elapsed, the DC/DC converter (1) is switched off if this time ends within the switching time determined by the first timing stage (6), a memory stage (9) also being provided which is triggered by the measuring voltage regulator (3) via the second timing stage (7) and which stores a voltage drop occurring across the measurement sensor resistor (17) corresponding to the measurement current and supplies it to a measuring mechanism (10) after the time inherent to the second timing stage (7) has elapsed. Due to the construction according to the invention, the duration of an insulation measurement is now only dependent on the duration of the charging process of the system capacitance. It is no longer necessary to input a measuring time. <IMAGE>

Title: Lighting unit consisting of a transparent body illuminated from one side
Inventor: HOLZHAEUER EBERHARD
IPC: F21V3/00
Filed: 1982-07-21
Abstract: The invention relates to a lighting element consisting of a transparent body illuminated from one side and having an assigned light source. It is the object of the invention to create a lighting element which consists for the viewer only of the transparent body and has no separate light box. Furthermore, the light of the light source employed is to be better utilised. According to the invention, this object is achieved when there is inserted in the transparent body, which preferably consists of plexiglass, a cold-light lighting fixture such as, for example, a neon tube, whose ballast is arranged outside the transparent body. The light box hitherto indispensible is now completely eliminated, since the light source, preferably a neon tube, engages directly in the transparent body, which for this purpose has, for example, one or more bores of appropriate size. By contrast, the ballast, which warms up strongly during operation, is arranged outside the transparent body and is connected via a lead to the light source. It is thus now possible to set up the lighting unit according to the invention without the ballast or also the leads, which can easily be coated, being visible.

Title: Iris diaphragm that can be completely closed
Inventor: ZUEND ERNST
IPC: G03B9/00
Filed: 1982-07-28
Abstract: Iris diaphragm that can be completely closed, having two groups of diaphragm blade (4', 4") of which in the closed state at least one diaphragm blade of each group covers the centre. The diaphragm blades of each group are rotatably mounted on an adjusting ring (2) and each guided in a housing half (1'). Mounting is preferably served by bearing pins (5'), which mount an end of a diaphragm blade (4') with respect to a housing half (1') or with respect to the adjusting ring (2). It is preferable to provide, for the purpose of guidance, radial slots (7') at the other end of the diaphragm blade (4'), into which slots guide pins (6') engage. The guide pins are seated on the housing half (1') or on the adjusting member. As a result, it is possible with a housing of very flat design to achieve diameter ratios of less than 1:1.5 between the largest effective camera aperture and the outside diameter of the housing. <IMAGE>

IPC: B65G15/42
Filed: 1982-10-19
Abstract: The invention comprises a roller conveyor belt and a conveying trough, formed of flat conveyor belts and corrugated belts, or sliding plates, characterised in that the roller conveyor belt is arranged at a right angle (see sketch) to the conveying trough and deposits the material for weighing into said trough.

Title: Dynamic pressure log device for ships
Inventor: NIEGEL DIETER
IPC: G01P5/14
Filed: 1983-02-19
Abstract: A dynamic pressure log to which is connected a device for electronic further processing and correction of the measured values is used to measure the speed of ships. The differential pressure measuring instrument (10) is arranged at the input (8) of a flow duct (7), the static and total pressure being measured approximately at the same location. The measured differential pressure is transmitted electrically to an adjusting unit (22), where it is converted into values corresponding approximately to the speed. These values are corrected in a following correction unit (23), e.g. in accordance with the flow conditions in the case of a circular course, or with the rudder position. The corrected speed value is displayed and used to calculate as a function of time the distance travelled and, as the case may be, to record the route travelled. <IMAGE>

Eine Dosierungs-Vorrichtung (9) kombiniert mit einer Abfall-Vorrichtung gehört zur Grundausstattung.  Die Funktion einer TER-Energiequelle: die im Reaktor (1) erzeugte Wärmemenge wird mittels eines Magnetfeldes im Reaktor (1) eingesperrt und erhitzt ständig den Heißwärmeleiter (2). Abwechselnd wird mit Hilfe der beiden Umwandlungsleiter (3, 4) elektrische Energie erzeugt.  TER-Energiequellen eignen sich vorzüglich in erster Linie als Energiespender für "Neuartige Antriebs-Systeme" (NAS) in der Luft- und Raumfahrt und zweitens für Siedlungen, die die Menschheit in Zukunft im Weltall und auf dem Meeresgrund errichten wird.

Title: Permanent-magnet AC motor
Inventor: POHL MARTIN
IPC: H02K21/12
Filed: 1983-09-21
Abstract: The permanent-magnet AC motor differs from conventional DC motors essentially in the construction and the method of operation. The arrangement of the coils with respect to one another and their interaction with the stator and the permanent magnets allow optimum utilisation of the electromagnetic fields. In conjunction with the force of permanent magnets, which are utilised to an extent of 50%, the permanent-magnet AC motor represents an extremely economical electric motor. A test indicates the economy of the permanent-magnet AC motor. A DC motor and a permanent-magnet AC motor are connected in series to a pulsating DC current. (The permanent-magnet AC motor also runs with DC current.) Both motors have the same resistance. The permanent-magnet AC motor governs the pulsating DC current. When switched on, the DC motor accelerates to maximum speed and the permanent-magnet AC motor accelerates slowly. The permanent-magnet AC motor becomes faster, and the DC motor becomes slower. When the permanent-magnet AC motor is rotating at maximum speed, the DC motor is stationary which means that when the power consumption is at a minimum the permanent-magnet AC motor runs at its fastest and the DC motor is stationary. This indicates that 50% of the force of the ... Original abstract incomplete.
