Filed: 1967-07-04
Abstract: 1,179,328. Automatic speed control. BROWN, BOVERI & CIE A. G. July 4, 1967 [Oct. 29, 1966], No. 30811/67. Addition to 1,090,110. Heading G3R. [Also in Division G1]. The system for controlling the variable pitch propellers of ships according to Specification 1, 090,110 is modified by the introduction of a delay circuit on the input side of the limiting controller 24. The resistor 31 is connectable in series with diode 32 and resistors 33, 34, which are also associated with the tachometer generator 23. When the master transmitter 9 is adjusted, a unit 36 releases a pulse whereby time-lag relay 35 connects resistor 34 to the input of the controller 24. The time constant of the control circuit then is such that the speed deviation signals are transmitted without delay. When the master transmitter 9 is not adjusted but the load on the propeller shaft is increased due to external causes, the signals representing speed-deviations are transmitted to the controller 24 directly through the diode 32 so that there is no delay. If there is decreased load on the propeller shaft, correction is effected according to the time constant of the circuit including the resistor 33, and takes place at a slower rate.
Patent GB-446285-A (GB)
Title: Improvements in the manufacture of porous blocks from chlorinated rubber
IPC: C08J9/28
Filed: 1934-10-26
Abstract: Porous blocks of chlorinated rubber are made by treating a suspension of chlorinated rubber in water with a small amount of an aqueous emulsion of a high-boiling, water-insoluble plasticizer, filtering off the water, and drying in a mould at a temperature sufficient to enable the plasticizer to soften the surfaces of the particles, and cause them to cohere.  Slight pressure may be applied during the drying of the block to assist cohesion.  Suitable plasticizers are chlorinated paraffin wax tricresyl phosphate, or dibutyl phthalate, of which 5 per cent on the weight of chlorinated rubber has been found sufficient.  The preferred temperature of drying is 120-140 DEG C.  The moulds may be glazed to facilitate removal of the block.  For blocks of intricate shapes, the suspension may be poured into moulds of fine gauze; centrifuging removes the water, and applies the pressure necessary for cohesion.
