Abstract: 867,219. Wood substitutes. SCHENCK MASCHINENFABRIK G.m.b.H., CARL. Jan. 9, 1959 [Jan. 21, 1958], No. 943/59. Class 70. [Also in Group XXX] Panels are formed from loose raw material such as shredded wood by scattering the material from at least three charging stations on to a continuously moving support, such as a belt conveyer, to form a continuous layered strand of approximately uniform width and depth, the charging stations which form the outer layers of the strand serving to segregate different particle sizes so that the finer particles are on the outer sides of the outer layers, the other station(s) being operated without any segregating effect. In the apparatus for chipboard manufacture, as shown, chips fed to moving belts 2a, 2b, 13 are removed therefrom by stripper rollers 7a, 7b, 7c and fed to scatter rollers 8a, 8b, 8c which form a bed of chips on a moving band 6. The rollers 8a, 8c are ribbed or spiked and scatter the chips forming the outer layers of the bed, arranging them with the smaller particles outermost in both layers. A deflector b mixes the particles from the roller 8b which form the central layer of the bed which is levelled by a spiked roller 10 which removes any excess and transfers it to a belt conveyer 11. The chips are supplied from a hopper 1, having a collector belt 3 and an ejector belt 2 which feeds the belts 2a, 2b, 13 through distributer flaps 4 and 5. Any excess on the belt 13 is removed by a spiked roller 14 and transferred to a belt conveyer 16. The chips on the belts 2a, 2b pass under back-raking spiked belts 3a, 3b. Alternative means such as vibrating screens or air blasts may be used to produce the segregating effect on the chips forming the outer layers of the band.

Filed: 1983-01-07
Abstract: PURPOSE:To prevent erroneous measurement caused by voltage creep, by a method wherein the output frequency of an electric power-frequency conversion circuit is compared with a predetermined cycle and, when the cycle of the output frequency becomes longer, an offset signal is supplied to the electric power- frequency conversion circuit. CONSTITUTION:An electric power-frequency conversion circuit 10 inputs load voltage V and a load current I and outputs a pulse line (f) proportional to electric power. The pulse line (f) is divided by a frequency divider 12 and electric energy is displayed by a counter 14. A cycle comparison circuit 16 is connected to the output side of the circuit 10 and, when the pulse line (f) is larger than a predetermined cycle, a minute signal generating circuit 18 is operated and a predetermined minute signal is applied to the circuit 10 in a direction reducing the pulse line (f). In this case, the cycle set by the circuit 10 is set so as to become slightly larger than the cycle of the pulse line (f) when the current I is zero and, further, the minute signal is not added. In addition, the minute signal applied to the circuit 10 is set so as to bring the pulse line to zero when electric energy for generating the pulse line with a set cycle is inputted. By this method, erroneous measurement caused by voltage creep can be prevented.

Title: Method of controlling diversity
Inventor: TODA YOSHIFUMI
IPC: H04B7/26
Filed: 1992-01-07
Abstract: PURPOSE:To minimize a mobile station device and to make the device light in weight and to reduce the power consumption by switching a transmission antenna using a space diversity switch control signal from the corresponding base station reception section. CONSTITUTION:A modulator 212 on a transmission section 21 at a base station #1 generates the frequency modulation wave corresponding to a modulation signal #1 by using the carrier of the frequency from an oscillator 211 to send it to the transmission switch 213. A switch 213 sends the modulation wave to a coupler 511 or 521 according to the state of the diversity switch control signal from a reception section 31 at the base station #1. Assuming that it is sent to the coupler 511, as the modulation wave of the other frequency is applied from the transmission section of the other base station, the modulation wave is arranged on the frequency axis. After commonly amplified by a common amplifier 512, the excess wave component is removed by a band-pass filter 513 at the transmission side and sent as a transmission signal from an antenna ANT5 to the mobile station. Thus, it is equivalent to receive a signal from the base station by using one reception antenna in the mobile station and the reception SD system on the reception side.

Filed: 1990-01-06
Abstract: PURPOSE:To perform the absolute search of a program number even at the time other than a reproducing time by providing a 3rd means for arithmetically operating the program number at a searching position based on the program number read out by a 1st means and the number of index signal detected by a 2nd means. CONSTITUTION:A servo circuit 33 (the 2nd means) reads out a control pulse from a magnetic tape 31 and supplies it to a mechanical control CPU circuit 34 as an index signal. The mechanical control CPU circuit 34 (the 3rd means) counts the number of index signals(control pulses) and the program number at the searching position is arithmetically operated based on the number and the program number read by a PCM circuit 32. Then, the CPU circuit 34 compares the program number which should be searched with an arithmetic operated value and controls a searching action. Thus, the absolute search is performed by using the program number while a recording medium is moved at a high speed by a fast-forwarding action or a rewinding action.
