A device for use in conjunction with a slice lip adjusting mechanism for controlling the distribution of stock across the web of a paper machine to obtain a desired cross-machine profile of basis weight, moisture, caliper and the like. The device is used in conjunction with a slice body and a slice lip which abuts the body but is at least slightly movable relative thereto. An apertured adjusting a...

A thermal limiting device for controlling one or more sources of infra-red radiation, preferably tungsten-halogen lamps, mounted in heating apparatus, consists of a metallic wire arranged to de-energize the sources when it is subjected to a predetermined temperature. The wire is accommodated within a quartz tube, which selectively transmits and absorbs infra-red radiation of different wavelengths....

Procedeu de obtinere a unui catalizator de argint utilizat la fabricarea oxidului de etilena care consta în impregnarea unui suport poros, rezistent la caldura, cu solutii continând complecsi de sare de argint-amina si compusi au unui promotor ales dintre: potasiu, rubidiu, cesiu sau un amestec al acestora, într-o concentratie astfel aleasa, încât argintul sa fie în catalizator în proportii de 3.....

In a procedure for starting an asynchronous motor, transferred voltage increases quickly until a change in the phase shift derivative between applied voltage and the input current is detected. Thereafter the input voltage increases more slowly until the input voltage has reached its total value. A device for execution of this procedure has a current detector (5) for generating a signal representin...

The pusher conveyor uses a power-reciprocated guide element containing a swivel plate which slides between the channel walls and forms an entraining angle with these in the feed direction but does not carry the manure etc. back in the return movement. - The channel (1) tapers towards the outlet end and the angle formed between plate (14) and wall (4,8) becomes more acute as the channel tapers, pre...
