Granted: 1987-06-18
Abstract: A process for removing by product acetone from reaction mixtures obtained by reacting methyl acetate and/or dimethylether with carbon monoxide at elevated temperatures to obtain acetic anhydride in the presence of a catalyst system consisting essentially of carbonyl complexes of noble metals belonging to group VIII of the Periodic System of the elements, acetic acid, an organophosphorus or organonitrogen compound, and methyl iodide whereby the acetone obtained as a by-product during the reaction is subjected to condensation at temperatures of 50 DEG  to 250 DEG  C., under pressures of 0.01 to 150 bars and at a molar ratio as above defined for the catalyst system constituent of 1:(25-500):(10-100):(15-150) so as to obtain predominantly higher-boiling secondary products to be distillatively separated in a successive distillation zone together with volatile constituents of the catalyst system.

Title: Veneer cutter trunk centering and clamp axis determn. - with reference point moved crossways to position between next and opposite points
IPC: B27L5/02
Filed: 1970-09-09
Abstract: The process is for determining the clamping axis and for centering, where round timbers are being cut in veneer paring machines. The timber is controlled in a number of sections at set intervals from the end faces, with setting values stored in cartesian coordinates or similar. The smallest interval from one of the reference points (O) is established, and this point is moved far enough away in cross-section for it to take up a centre position between the next point and the 180 deg. opposite peripheral point. The stored setting values of all the comprises peripheral points are transformed to the new reference point (O1, O2), or the changed value are comprised anew.

Title: PAL-NTSC-SECAM standard converter for inter-country transmissions - increases colour amplitude before conversion and reduces it again later
IPC: H04N11/20
Filed: 1970-09-28
Abstract: The PAL/NTSC-SECAM standard converter, for transmission between countries using different tv standards, increases the amplitude of signals having low colour saturation to a higher level of colour saturation before the actual standard conversion process takes place. After the conversion is complete the amplitude is reduced by the same amount as it was increased earlier. Raising and lowering the amplitude in this way improves the quality from the FBAS signal and changed-over to a carrier frequency suitable for the conversion, it is passed to a first gain-controlled amplifier, and after conversion and extraction of the reference signal it is passed to a second gain-controlled amplifier.
Patent DE-2101569-B2 (DE)
Title: Electrolytic cell with two compartments - has thin porous diaphragm as separator dividing electrolyte flow to reduce internal resistance
IPC: H01M8/08
Filed: 1971-01-14
Abstract: The electrolytic cell has a thin coarse-grained porous diaphragm between its cathode and anode plates which divides that region into two parts. The electrolyte flows through channels in the base of the cell separately into the two spaces, and leaves through separate outlet channels in the top of the cell. Allowing the electrolyte to flow through the anode and cathode spaces separately considerably reduces the cell's internal resistance. The electrolyte's common inlet channel is best sited at the corners of the frames supporting the cathode, anode and separator diaphragm. (The diaphragm has a mesh spacing of 85 mum).

Title: Analog signal switching gate cct. with FETs - reduces voltage peaks caused by gating pulses by FETs switching using control voltage applied to gate electrode
IPC: H03K17/16
Filed: 1973-07-19
Abstract: The FET gate for analog signals is designed to reduce voltage spikes caused by the edges of the rectangular gating signal. The analog input signal passes over two channels (A1B). The first channel contains a first FET source/drain path (1), and the second contains a polarity inverter (3) and a second FET source/drain path (2). The gates of the two FETs are connected separately over two diodes to a common gating signal (US). A d.c. voltage (+U) is added to the analog signal at both the FET input electrodes to suppress the voltage spikes produced by polarity changes in the gating pulses. The FETs output electrodes are connected to a subtraction circuit (4) to obtain the composite gate single output (UA).

Abstract: PURPOSE:To provide a communication system where communication can be performed regardless of the state of a reception side and communication range is wide. CONSTITUTION:Transmission data from the main body equipment on a transmission side is received at a communication module part 1 6 and is outputted to a CPU part 11 via in I/O part 19. After the reception, the CPU part 11 outputs the data received via the I/O part 14 to a communication module part 17 and the communication module part 17 transmits the data inputted to the main body device of the reception side. After the transmission, the CPU part 11 judges whether the main body device of the reception side is in a reception possible state or not based on the response state from the main body equipment of the reception side. When the state is the reception possible state, received data is transmitted as it is. When the state is the reception impossible state, the received data is stored in a RAM part 13 and after the main body device of the reception side becomes the reception possible state, the data is again transmitted.

Abstract: A plunger mechanism for forming a hollow article of glass in a "narrow neck press and blow" operation which utilizes an electro servo-driven leadscrew to actuate it. A position sensing resolver is used to determine the position of the plunger over the full range of its stroke, and the position information can be used as feedback to control the position of the plunger prior to contacting a molten gob of glass in a mold chamber. The depth of the plunger penetration into the molten gob is then controlled by the pressing pressure, which is a function of motor torque and screw mechanics. It is possible to control the pressure exerted on the molten glass gob by controlling the torque applied by the motor. A separate gob weight controller is not required because changes in gob weight can be determined by closely monitoring the plunger penetration of the gob. <IMAGE>
