Abstract: A platen press has a pair of platens having respective confronting and parallel pressing surfaces and each having a pair of longitudinal edges. Respective spacer bars are fixed to the longitudinal edges of one of the platens and have respective spacer surfaces parallel to and between the platen surfaces. Respective adjustments bars are secured to the longitudinal edges of the other of the platens and each have an adjustment surface parallel to and confronting the respective spacer surface. Each of these adjustment bars is formed of an outer wedge having a pair of nonparallel faces one of which is the respective bar surface and of an inner wedge having an outer face flatly engaging the other face of the respective outer wedge. The inner and outer wedges can be relatively longitudinally displaced so as to displace the respective abutment face perpendicular to the respective platen surface. Thus when the platens are displaced together perpendicular to the surface the spacer surface flatly engages with the respective adjustment surface, holding the pressing surfaces apart at a distance equal to the thickness of the spacer bar plus a finish increment set on the adjustment bar.

Abstract: Apparatus for measuring the flow rate of a flow, stream or jet (1) of a molten, radiation-emitting material, in particular molten glass or ceramic or mineral materials, comprising two radiation detectors (S1, S2) arranged to detect the radiation emitted from a limited section of the material flow at two mutually spaced locations along its path. The output signals of the detectors are applied to signal-processing circuits (ST1, ST2), which discriminate therefrom all pulse-like amplitude variations (P) exceeding a given specific magnitude and provide corresponding signal pulses (P min ) on their outputs, said pulse-like amplitude variations originating from randomly occurring, local deviations in the radiation from the material flow (1) due to the presence of gas bubbles in the material. The time interval between the occurrence of a signal pulse on the output of the signal-processing circuit (St1) of the upstream detector (S1) and next following occurrence of a signal pulse on the output of the signal-processing circuit (ST2) of the downstream detector (S2) is determined by starting a digital counter (R), which is driven at a constant frequency, with the first-mentioned signal pulse and stopping the counter with the second signal pulse. The resultant count in the counter (R) is transferred to a calculating unit (D), which calculates the flow rate of the material flow on the basis of sad count and the distance (L) between the detecting locations of the detectors (S1, S2). A gating circuit (B) is connected between the signal-processing circuit (ST1)  of the upstream detector (S1) and the counter (R) for blocking the transfer of any signal pulse occurring on the output of said signal-processing circuit within a given time interval after a preceding occurrence of a signal pulse on said output.

IPC: G11B20/04

Abstract: A frequency dependent circuit is located in the main signal path of a dual path compressor or expander in which the main signal path is linear with respect to dynamic range and a further path provides a signal which boosts or bucks the main path by way of a combining circuit, but which is so limited that in the upper part of the input dynamic range the further path signal is smaller than the main path signal. The frequency dependent circuit in the compressor is called an antisaturation network with a characteristic FAS such as to effect a reduction in frequency response in the frequency band affected by overload in a transmission channel fed by the compressor, typically the upper end of the overall frequency band. The expander which is fed by the channel has a complementary antisaturation circuit with a characteristic F'AS providing a complementary increase in frequency response. The arrangement provides level dependent equalization without significantly affecting the noise reduction effect of a compressor/expander system because in dual path compressors and expanders the output of the circuits at very low signal levels is provided mostly by the further path. Thus, at high levels, where channel overload is a problem, the frequency dependent circuit is effective, while at low levels, where it is not desired or needed, the equalization effect is reduced. <IMAGE>

Abstract: The present invention is a method of measuring the temperature of a hot crystalline material. It is especially well adapted for measuring the temperature of mineral products within or being discharged from rotary or other types of kilns. The mineral material entering the kiln is doped with a rare earth compound at a level of at least 0.001 molar percent, preferably about 0.01 molar percent. During the process of calcination in the kiln, the rare earth is incorporated into the crystal lattice of the host mineral to form a phosphor. This is excited by laser light of an appropriate wavelength. The flourescence emitted by the excited hot material is then measured and can be accurately related to the temperature. In one version of the invention the mineral material is used in a chemical process where it is recycled to the kiln for recovery. The lime cycle in a kraft pulping operation is such a process. In this way there is minimal loss of the rare earth material and all that need be added is a sufficient amount to make up process losses. Under such operating conditions the cost is minimum and is minor when compared to the potential savings in fuel by avoiding overburning. However, the amounts of rare earth dopant used are sufficiently small so that the process can be used with other calcined materials, such as cement, which are not recycled through the process. Praseodymium is a preferred dopant for use with lime kilns.
