Title: Filter circuit attenuating noise signals - has capacitor and resistor in series to suppress rising slope of abnormal voltage and nonlinear voltage sensitive resistor
Inventor: YOKOYAMA YOSHIKI
IPC: H04B15/02
Filed: 1977-03-11
Abstract: The filter circuit is for attenuation and absorption of noise signals generated in a reactive load when either d.c or a.c is interrupted. The circuit consists of a resistor (44) in series with a capacitor (55) connected in parallel with the reactive load (43). A nonlinear, voltage sensitive resistor (46) is connected in parallel with this series circuit and the reactive load (43). The potential generated at the load (43) when the switch (42) is open is suppressed by the filter circuit. The rising slope of the abnormal voltage is weakened by the capacitor (45) and resistor (44) so that the noise signal is prevented from spreading out into the surrounding space or air. The peak value is suppressed by the resistor (46).

Title: Window display system with fixed guide rails - has decoration elements with guide pins fitting into rails
Inventor: STEINBERG JOCHEN
IPC: A47F11/02
Filed: 1977-04-30
Abstract: Window display system comprises two or more decoration elements which are held and arranged in fixed guides by means of guide pins fitted to the upper and lower ends of the elements. The guides are pref. made from rails of U-shaped cross-section and can be made up into rectangular grids or screens (27) in a row, with the guide channel being continuous. The decoration elements can then be held in square grids with the width of the element corresponding to the side of the grid. The number of decoration elements is such that they fill both the width and the height of the window. Since the decoration elements can also be arranged in tiers they can fit diagonally into the grids. The window decoration can be completed from inside the room and a new display can be easily fitted into the window so that the latter never remains empty whilst a new display is being prepared.

Title: Composite steel plate cutting procedure - involves imparting oscillating motion to cutting wheel rotating at given speed
IPC: B24B27/06
Filed: 1977-06-01
Abstract: The slitting wheel is rotated to obtain a peripheral speed of 30-100 m/s, and is also subjected to an oscillating motion with frequency 10-320 strokes/minute. The plate has a soft, tough side, a middle, mixed zone and a hard, wear-resistant side. A suitable manufacturing method is cast two steels ina mould contg. a dividing wall made of steel plate and forming the middle zone after rolling the cast ingot to the required thickness. The plate is used e.g. in metallurgical works or ore mines to make conveyors or containers, where steel forms the wear-resistant side of the equipment. The cutting procedure permits the use of commercially available slitting wheels which are bonded with synthetic resins and reinforced fibres; and esp. using corundum as the basic abrasive in the slitting wheel. All high power machines for cutting steel are suitable. The slitting wheel can be used esp. for plate up to 100 mm thickness.

Title: Double effect separator to remove solids from gas streams - uses cyclone and filter, with the filter having a by=pass valve and passage if damp materials liable to clog the medium are handled
Inventor: HERDING WALTER
IPC: B01D46/02
Filed: 1977-07-20
Abstract: Solid particles suspended in air or other gas streams are removed by a system having a coarse separator (e.g. a cyclone) banked up by a fine separator such as a bag filter. Each has a collection space for the sepd. solids. The filter consists of a series of cylindrical sleeves suspended between mounting plates. The unit has an inlet shaft which takes the air to the base of the sleeves and allows it to flow upwards through them. The solids are deposited on the inside and are removed by a shaker mounted on the top. The clean air collects in a shaft on the side and is extracted by a fan. The bottom of this shaft connects with a bypass valve at the base into the dirty air space. The clean air inlet to it is via a pinch valve. When the latter closes and the bypass opens, the flow through the bags is stopped. The device is esp. used with large boring machines to prevent environmental pollution. Existing systems have a tendency to clog up esp. when handling damp material, necessitating a complete shut down. The construction gives a simple means of overcoming this problem.

The pivot pin (10) for the arm is located between the hinge pin (5) and two stops (21, 22) attached to the outer end of the outer bearing part (4). The swinging arm (15) is locked onto one of these stops for its raised or lowered position.
Patent DE-2744200-A1 (DE)
Inventor: EISL ENGELBERT
IPC: H04Q3/00
Filed: 1977-09-30
Abstract: To monitor the identification result obtained on the basis of an identification request in telephone switching systems, this result is derived from the evaluation of a number of transmitted identification signals. It is output separately for the individual digits of the line number as digital code signal at the output of a coding unit (CE) in each case allocated to a group of subscribers and connected at the input end to a subscriber-individual subscriber/counter connection and supplied to a central evaluating and control device (IDZ) for further processing. For each input line (K) of the central evaluating and control device (IDZ), the output signals of the coding unit (CE) are compared with the control pulse triggering the identification signal and determining its duration. During the processing of an existing identification request, the test result is checked as a whole. Among other things, the results obtained with a number of identification signals are compared with one another. The code used for representing the respective numerical value is also monitored for its correctness. <IMAGE>

Title: Pivoted keel for sailing craft - has split construction to support craft on land in splayed condition
Inventor: ZUEHLKE ERNST-W ING GRAD
IPC: B63B41/00
Filed: 1977-11-17
Abstract: The keel of the sailing craft is divided into two sections about a middle vertical line. Each section can be swung to one side by servo rams to form a splayed shape and allow the craft to sit on the mud when the tide is out. The design prevents the craft from tipping as it settles on the mud and provides for a large single keel for optimum sailing. The splayed shape can also be set in order to reduce the water depth required in shallow waters.
