Title: Tension-roller arrangement on tangential-belt drives for spindles of spinning and twisting machines
Inventor: BLOCH PETER
IPC: F16H7/12
Filed: 1981-02-20
Abstract: A tangential belt (3) driving the spindles of spinning and twisting machines is assigned tension rollers (5) which press it against the spindles (2) and which are mounted overhung on angular supporting pieces (9) arranged at the free ends of an elastic holder (8) fastened in its middle region to the machine. So that tension rollers of larger diameter than usual, which, because of their rotation speed which is then lower, require correspondingly less drive energy, can be accommodated in the space available for a tension-roller arrangement of this type, the legs (9a), projecting from the holder (8), of the supporting pieces (9) possess portions (9b) which project in the longitudinal extension of the holder (8) beyond the free ends of the latter and on which the tension rollers (5) are mounted so as to project beyond the plane of the holder (8) on both sides. <IMAGE>

Title: Electric shaver system
Inventor: DILLNBERGER KARL DIPL ING
IPC: B26B19/26
Filed: 1981-03-11
Abstract: Conventional electric shaver technology can be improved by adding a new movement, which is approximately perpendicular to the skin, to the vibrating or rotating cutting mechanisms. The new movement may be derived from the existing drive mechanism, may be by means of a separate force acting mechanically or pneumatically, or may indirectly cover the surface of the skin by means of finger-like surfaces acting approximately perpendicularly, to achieve the new, vibrating movement. When a pneumatically operating force is used, it is possible to collect the cut-off bristles by means of the suction effect and to remove them as waste.

Patent DE-3127035-A1 (DE)
Inventor: GLAESER KARL CHRISTIAN ING GRA
IPC: B24C1/00
Filed: 1981-07-09
Abstract: For sand blasting a stream of a suspension of a carrier gas and solid particles under superatmospheric pressure is restricted so that it is accelerated, and a liquid-carrying additive gas is mixed with the stream to moisten the particles. The additive gas is introduced into the stream at a pressure greater than the pressure of the stream at the location by between 1.5 and 2.5 times. Normally the additive-gas pressure is about twice the carrier-gas pressure, that is the additive gas is normally introduced at a pressure of between about 10 bar and 30 bar. This high-pressure introduction ensures that the additive gas enters well into the carrier-gas stream so that the liquid carried by the additive gas contacts and wets the solids carried by the carrier gas without just passing through it and wetting the inside of the sand-blast mix nozzle. The additive gas is introduced into the stream in a unit of time at a rate sufficient to introduce into the stream a quantity of the liquid equal to between about one-twentieth to one-thirtieth, preferably one-twenty-fifth, the mass of the particles passing the location during the unit of time.

Title: Method of dividing wide metal strips
Inventor: MERZWEILER HORST
IPC: B23D31/00
Filed: 1982-03-05
Abstract: The invention relates to the longitudinal dividing of wide metal strips into shaped strips with periodically alternating outer contour for obtaining blanks in a material-saving manner for further working by the pressing technique and sheet-metal working by making continuous predetermined breaking notches in the metal strip to be subsequently pulled apart in the notches. The predetermined breaking notches are made by continuously partly overlapping local notching by means of granular crushing bits which are moved away in a controlled manner transversely to the running direction of the strip in accordance with the preset blank contours. The use of the invention enables the outer contour of the shaped strip to be adapted in a largely material-saving manner to the contour of the blanks to be obtained and only needs one tool set despite the possibility of producing diverse, rounded or cornered blank shapes. <IMAGE>

Title: Circuit arrangement for producing a change-up signal in internal- combustion engines with multi-speed gears
Inventor: HAUBNER GEORG
IPC: F16H63/42
Filed: 1983-02-12
Abstract: A circuit arrangement for producing a change-up signal for the multi-speed gears of an internal-combustion engine is proposed, by means of which the greatest possible saving in fuel is to be achieved. For this purpose, the actual fuel consumption is directly detected by means of a fuel consumption meter (29) and the respective engine speed is detected by means of an engine-speed signal generator (58). In an electronic control circuit, the performance/engine speed group of characteristic curves of the internal-combustion engine is stored and divided up into a favourable and an unfavourable working range. The control circuit (10) determines in each case the momentary operating state of the internal-combustion engine from the signals of the engine-speed signal generator (58) and of the fuel consumption meter (29) and emits a change-up signal when the detected operating state is in the unfavourable region of the group of characteristic curves. The circuit arrangement can preferably be used for motor vehicles. However, it can also be generally used for internal-combustion engines with multi-speed gears. The change-up signal can be used both for a gear control and for a visual display. <IMAGE>

Patent DE-3315548-A1 (DE)
Inventor: WASSILIEFF VICTOR
IPC: B65D55/02
Filed: 1983-04-29
Abstract: A child resistant closure for bottles is provided that permit closure withdrawal by exerting an axial force and a simultaneous rotating movement. For this purpose, a clutch is provided between an inner cap and an outer cap of the closure with at least one elastic flexible clutch element which is ineffective in its rest position and which is deformable upon application of an axial downward force. In this manner, a sufficient friction lock is generated between the two caps, so that the outer cap takes along the inner cap during screwing on and unscrewing off. In the absence of the axial force the outer cap will slide over and not turn the inner cap.
