As shown the pump (5) has two speeds selected by switching amplifiers (16,17) and respective relays (18,19) in dependence on the external temperature TA. The control signal IW is derived as the mean of the feed and return water temperatures THV, THR by sensors (13,14). The system can thus function efficiently both at normal and maximum heat demands and with a single setting means (12) responsive to external temperature TA. <IMAGE>

Title: A method of producing shaped bodies
IPC: D21J1/20
Filed: 1981-02-03
Abstract: A method of producing shaped bodies of plastics bonded lignocellulose components includes the steps of suspending the lignocellulose components and the thermoplastics in an aqueous medium, dewatering the suspension, shaping the mixture and drying the shaped bodies. Polyolefin particles are used as thermoplastics for the formation of the suspension and the shaped bodies formed are subjected to a thermal aftertreatment in which the polyolefin particles melt together into a matrix that increases the strength of the shaped bodies.

Title: Process and Installation for the Continuous Heat Treatment of Steel Sheet
IPC: C21D9/56
Filed: 1981-10-30
Abstract: For the purpose of providing sheet with both a high elasticity limit and a good suitability for stamping, a steel containing at most 0.16% of C, 2.0% of Mn, 0.55% of Si and at least 0.03% of Al, and also, if appropriate, up to 0.05% of Nb and 0.1%of V, is used.

The sheet is then cooled at 100 DEG C/second to a temperature below the Ar1 point and the sheet is left to cool at a rate of about 1 DEG C/second. The tempering level is between 550 and 650 DEG C, preferably at 600 DEG C, and it is produced by immersing the sheet either in a liquid medium for example a bath of salts or of metal, or in a gaseous medium. Apparatus includes a heating zone 4, soaking zone 5, and gas cooling unit 6 or metal or salt bath 7, followed by slow cooling zone 8. Before undergoing slow cooling the sheet may be chromium-plated. <IMAGE>

Title: Simulated stereo from a monaural source sound reproduction system
Inventor: GREENE BICE ROBERT
IPC: H04S5/00
Filed: 1981-11-09
Abstract: A source 110 of monaural sound such as a radio receiver or record player provides an audio signal which is fed along parallel paths 115 to a like number of speakers 116. In one or more paths there is a control 114 which imparts amplification or gain to the signal. In the other path, however, a frequency dependent amplitude variation and phase delay means 117 is interposed in the circuit. It is the purpose of this means to vary the amplitude response of that signal to introduce a bass boost of about a factor of two and a treble cut of about a factor of ten and to vary the phase shift of that signal to introduce from about a 180 DEG  to about 225 DEG  phase lag to the monaural signal, the amplitude response and phase lag being a function of the frequency of the signal, to impart a simulated stereo effect to the sound as heard from the plurality of speakers. <IMAGE>

Title: An improved optical fibre
IPC: C03C13/04
Filed: 1982-05-07
Abstract: A graded index optical fibre in which a fluorine-bearing compound is used as a refractive index depressing dopant in both the barrier layer and the core of the fibre to compensate for the sudden introduction of GeO2 at the barrier-core interface. The sudden increase in the value of the refractive index from the barrier layer to the core is therefore removed by the presence of the fluorine-bearing compound, thereby increasing the bandwidth of the fibre.
