A method of cutting non-metallic materials, specifically glass, resides in the heating of the material by an incident beam of radiation being effected to a temperature short of its softening point, with the rate of relative displacement of the beam and of the material, and the region of the heated zone which is locally cooled being selected to form a blind crack in the material. The method provide...

In an electronically controlled automatic transmission system including a gear transmission (5) and a clutch (4), in which a target gear position is determined in accordance with map data for gear shift control, it is discriminated whether or not the vehicle is in accelerating condition and necessary control for shifting up the transmission to the target gear position is carried out only when the ...

In a system for evacuating air from moulds for vulcanizing tyres, the air and vulcanization gases trapped in the various interstices of the mould (1) are evacuated to the outside of the moulding part through a part which serves as a vent (3) and which contains one or more direct passage chambers (4) of constant width on the so-called bottleneck part which are dimensioned so as to prevent the passa...

A method of and an apparatus for controlling the revolution speed of an engine, suitable for use in an automobile having an automatic transmission. Flow rate of auxiliary intake air by-passing a throttle valve is controlled by an auxiliary air control valve, the opening period of which is incremented in response to a signal which represents the state of the automatic transmission shifted from neut...

The large bundle of drawings (24) is laid on the base of a housing (2) under a plate (11). At one end of the housing is a margin punch (10) activated by an electromagnet (26), and located above a guide channel (6) and margin guide (7). The bundle is supported underneath before and during the punching operation by a support activated by another electromagnet. A sensor is in contact with a control a...

Process of finish-grinding rings on the outer surface or inner surface, especially for finish-grinding race rings of rolling bearings. A ring to be machined is accommodated by a work fixture with centring via a hydraulic centring means and is driven in a rotating manner by a driver. The ring surface to be machined is measured during a grinding operation. The grinding operation is regulated and/or ...

A leather layer is burned, preferably under a protective gas blanket, with a laser beam to increase the water vapor permeability for use of the leather in automotive vehicle seats.

Treatment of molten metal, esp. steel, with a purifying agent is characterised by the fact that liq. oxygen or a two-phase mixture of liq. and gaseous oxygen is used as the purifying agent. Oxygen is blown via a blow nozzle (1) in to or onto molten metal (3), with the pipe line (4) and/or the nozzle (1) cooled down so that oxygen has a temp. equal to or less than the boiling temp. of oxygen at a g...

The invention relates to a process for the preparation of lead battery plates to forming, by means of pasting, drying the plates, cleaning their lugs and parting the twin grids. In compliance with the process of the invention the twin grids are parted immediately before pasting the plates, and lug cleaning is carried out after the pasting and drying of the plates by eliminating the synchronization...

A slow scanning CT Scanner providing slice data simultaneously for a plurality of slices so as to avoid blurring between adjacent slices due to patient movement.

Dental floss provided with chemotherapy agents, including wax that is emulsible upon contact with saliva. State of the art dental flosses achieve an efficient release of active agents within the oral environment, by using soluble waxes, but said solution decreases comfort of application since there is a decrease in the levels of sliding and penetration between the teeth, in comparison to the use o...
