Abstract: The invention relates to a method and an arrangement for the separation of lighter particles (10) from heavier particles (3) in a liquid medium, which contains lighter particles and heavier sinking particles which require to be washed, in particular sand, and in particular at sewage works in the incoming waste water, where the heavier particles are removed at the lower end of a vessel and the lighter particles are removed at a level above the outlet for the aforementioned heavier particles. In accordance with the invention the level in the vessel (13) of the process water intended for washing the sand (3) is varied, so that a hydraulic pressure difference is achieved and the sedimented lighter material (10) that is not intended to be washed can be removed by decanting for a predetermined period of time by causing rotation (20) of the lighter material (10) so that it makes its way towards the centre at a level (14) above the upper level (22) of the sand. Washing water (23) and/or other fluid for washing the sand is also supplied.

Abstract: When manufacturing semiconductor lasers having an internal grating (5), such as DFB or DBR lasers, the facets (7) generally have an arbitrary position in relation to the grating. This varying position of a critical one of the facets results in the fact that many of the lasers obtain far from optimum performance. In order to obtain far from optimum performance. In order to obtain good optical performance a distance layer (23) is applied directly to the critical facet. The distance layer has a thickness adapted to the phase of light generated in the laser, in particular to the phase at the facet, thereby producing a desired reflection of the light in the distance layer to give the laser good performance.

Abstract: A deformable sealing member, particularly a sealing tube, which is at least partially elastic is secured at two distant locations to two working members, e.g. to a piston part and a cylinder part respectively to form a leakproof working chamber for pressurizing therein a working fluid or for transferring the power of a pressurized working fluid introduced in the working chamber to said working members, the apparatus thus being able to operate as a pump or motor respectively. The sealing member is supported against the working pressure in said chamber by a support surface, and between said sealing member and said support surface there being a low-friction component which is constituted by a solid material, e.g. a sliding layer, secured to the sealing member or to the support surface, or by a fluid lubricant introduced in a flow passage formed between the sealing member and the support surface, in the latter case there being a continuous or intermittent stream of lubricant through this lubricant flow passage at least during high-pressure strokes of the working chamber to a low-pressure side. The pressure in the lubricant flow passage is balanced against the pressure of the working fluid by throttle means formed by the gap between the deformed sealing member, when under pressure of the working fluid, and the support surface and automatically adjusted or regulated by the lubricant volume or pressure in said passage on one side and by the working pressure in said chamber on the other side so that substantial pressure balance between both surfaces of the sealing member wall will arise supporting the sealing member with distance from the support surface, i.e. substantially without friction and wear, and without excessive deformation. If solid low friction layers or surfaces are used, then "Teflon" or similar materials may be disposed on the sealing member and/or the support surface.

Abstract: The ink ribbon (2) from a continuous ribbon cartridge of a printing mechanism is transported by means of transport rollers (4). A slotted disc (16, 17) is driven directly by the ink ribbon as a reporting device for the ink ribbon. The rotary movement of the slotted disc (16, 17) is monitored by means of a light-emitting diode (19) and a phototransistor (20). The pulses of the phototransistor (20) are compared with a given value. If the pulse sequence drops below the given value, the printer is automatically switched off. If, consequently, there is no transporting of the ink ribbon as a result of an interference (tearing of the ink ribbon, interruption in the drive system), the printer ceases to print. The printing mechanism can thus operate without observation, for example at night. <IMAGE>
