Title: Excavator for railway track ballast - has wagon mounted mechanical shovel to dump ballast in hopper mounted over conveyor belt
Inventor: BUHLER FRITZ
IPC: E02F3/30
Filed: 1977-11-21
Abstract: The excavator consists of a mechanical shovel mounted on a railway wagon provided with two conveyor belts (4) which excavated ballast into another wagon. Behind the crane wagon and under its base but within the gauge of the track is a hopper (8) attached above the first conveyor and mounted on rail wheels (16). The hopper consists of a funnel (10) with one movable wall (9) which is provided with two arms (11) with friction rollers (12) which move in fixed guides (15). The extremities of these arms are joined to hydraulic jacks (13) which produce a reciprocating motion in the moving wall. Stops (14) on the roller level permit the jacks to tip the hopper upwards thus emptying the contents onto the conveyor.
Patent DE-2752607-A1 (DE)
Inventor: HAFER EDWARD HENRY
IPC: G10L15/00
Filed: 1977-11-25
Abstract: A speech recognition system is realized by applying a speech signal to a feature extractor wherein a sequence of predetermined features representing the speech signal are determined, and by comparing the determined features, in an acceptor, to predetermined sequences of features which represent selected words. One attribute of the feature extractor is the ability to represent certain classes of sounds in terms of the position and direction of motion of the movable structures of a human vocal tract model, such as the position and direction of movement of the speaker's tongue body. The tongue body position is derived by determining the formant frequencies in the applied speech signal and by employing the Coker vocal tract model to find the tongue body position which best matches the determined formants.

Title: Multilayer printed circuit boards mfr. - by hot pressing, allowing the electrical resistance of the binder to control the press cycle
Inventor: MACHMUDOV MARAT
IPC: B30B15/26
Filed: 1977-12-05
Abstract: Multilayer printed circuit boards are made by assembling a stack of printed layers which are sepd. by adhesive inserts coated on both sides with a binder. The stack is heated, while applying a low pressure, to liquefy the binder, and the vol. resistance (V-R) is measured during this phase of the pressing operation. As soon as the V-R has reached a min. value, a high pressure is applied at which the binder is polymerised. The pref. press is fitted with a control unit, where a meter measures the V-R of the binder and transmits a signal to a circuit connected to both a timing relay and a relay adjusting the drie unit on the press., i.e. so the high pressure is applied when the min. value of V-R is reached. Method is esp. for mfr. of large multilayer printed circuit boards with metallised through holes for making connections between the layers. Prior determination of optimum press cycle is obviated.

Title: Bulk material discharge from silo - modifies flow using pivoted inclined plates which remove support from bridging material
Inventor: GESSLER HANS
IPC: B65D88/64
Filed: 1977-12-23
Abstract: A device is used for modifying the discharge flow of bulk material from a silo. It comprises one or more support surfaces inclined relative to the vertical axis of the silo. The support surface (9) can be moved to vary its support to the silo contents. Pref. a number of inclined support surfaces (8, 10) are mounted so that they can move esp. pivot. More specifically, the support surfaces overlap (11) and generally form a cone, pyramid or similar tapering outlet mounted inside the silo (2). Each component plate (10) of the cone is pivoted, typically at its upper end, so that the supported material can be loosened by varying the angle of the plates. The system may be used for any type of bulk material which tends to jam and form bridges in a tall silo. The material is dislodged and allowed to fall when the plates are moved. A common adjustment device (16) typically a ring of variable dia., holds the support surfaces (10) in place. The ring may be composed of a cable with a turnbuckle.
Patent DE-2817648-A1 (DE)
Inventor: SATOH KATSUHIKO
IPC: G04C3/14
Filed: 1978-04-21
Abstract: In an electronic watch having an oscillator for producing a time base signal and stepping motor, drive pulses are produced for normally driving the motor under normal load conditions. The rotation and non-rotation of the motor in response to the last drive pulse is detected in response to a detecting pulse, and if non-rotation has been detected, a predetermined plurality of correction pulses are applied to the motor for driving same, the correction pulses being sufficient to drive the motor under a high torque loading. In this way, power consumption is decreased since a high power driving is saved only for high torque loading conditions.
