Abstract: In a method an apparatus for the heat treatment of gypsum or like material, in which the material is heated in a vessel (2) by indirect heat exchange with hot gas product by the fluidised combustion of a fuel, material is fed into a first fluidised bed (A) of the material. Partially treated material is removed from the lower region of the first bed (A) and introduced with the assistance of compressed air into the upper region of a second fluidised bed (B). Treated material is removed from the second bed (B). The beds (A and B) of material are both fluidised by means of the introduction of the hot gas product of the fluidised combustion bed, further heating the beds (A and B).

Abstract: A feedback control system and method for controlling the wheel slip of a wheel driven by torque coupled through an electronically controlled hydraulically operable clutch (22) from an internal combustion engine. A first feedback variable related to wheel slip and a second feedback variable related to hydraulic pressure applied to the clutch (22) are summed (12) to generate a feedback control signal. In response to the feedback control signal, the clutch (22) is slipped by regulating the hydraulic pressure to reduce the driven wheel speed. Engine speed is adjusted in response to a measurement of driven wheel speed to prevent over-revving of the engine and maintain a desired predetermined positive torque on the driven wheel while the clutch (22) is being slipped.

Abstract: Multi-coloured images are built-up from thermoplastic, separation negatives obtained for example on a laser printer. Coloured positive separations are obtained by applying a coloured, transferable non-thermoplastic layer on a carrier over each thermoplastic negative separation, subjecting the assembly to heat and pressure, and peeling apart the assembly whereby coloured non-thermoplastic positive images remain on the carrier sheet. Each coloured non-thermoplastic positive separation in turn is then transferred to a receptor having a thermoplastic surface. Each coloured, non-thermoplastic positive is applied over the receptor having a thermoplastic surface, the image being in contact with the thermoplastic surface, the assembly is subjected to heat and pressure and the carrier sheet removed to leave the positive image adhered to the thermoplastic surface of the receptor. This process is repeated for each colour positive separation to build up the multi-coloured image on the receptor surface.

Abstract: A hydraulic power steering apparatus having conventional relatively rotatable valve spool (54) and valve body (64) for flow regulation, a mechanically resilient element (90) for generating a mechanical centring force in relation to the relative rotation of the valve spool and valve body which tends to restore the valve spool and valve body to a centred condition, and an integral electromagnetic mechanism (92) which variably opposes the mechanical centring force to adjust the level of operator steering input required to produce a given level of power assist. The electromagnetic mechanism comprises an exciting coil (130) and a pair of flux conducting elements (106,108) supported for rotation with the valve spool and valve body, respectively. The flux conducting elements have interleaved teeth (112,114) which are magnetically coupled to the exciting coil to define a magnetic circuit having an inter-tooth working air gap which varies with the relative rotation of the valve spool and valve body.

Abstract: In the electric rolling stock running in a direct current feeder section, an accidental current has conventionally cut off by the DC high-speed circuit breaker. However, this circuit breaker is low in response to a steep peak of the accidental current and the circuit breaker at the substation is operated earlier, so that the accident in one train affects other trains in the same feeder section. So, attempts have been made to mount a DC high-speed vacuum circuit breaker which operates very quickly. In the conventional DC high-speed vacuum circuit breaker, however, it was impossible to obtain the commutation frequency of higher than 1 kHz, and to obtain such a high commutation frequency, the commutating capacitor and the other devices become very large in size. By this invention, with various inductances taken into consideration, it has been made possible to cut off a current at 2 kHz or higher and it has become possible to provide a DC high-speed vacuum circuit breaker (1) of the reduced size which can be mounted on the electric rolling stock.
