Patent DE-3213793-A1 (DE)
Title: Device for protection against short-circuits in high-power on-board networks
Inventor: HAGEMANN HANS-JUERGEN ING GRAD
IPC: H02H7/06
Filed: 1982-04-15
Abstract: The invention relates to a high-power on-board network having generators which are combined to form groups, operate on a busbar and are connected to the loads. Arranged between the generator groups is an electronic power circuit breaker which inserts a parallel resistance or a parallel inductance into the circuit if a predetermined excess current is exceeded. In order to reduce the previously necessary large space requirement and the large weight for the current transformer and rectifier, once the sub-transient equalisation process has decayed and/or the voltage has returned, the power circuit breaker will partially or completely bridge over, in a current-controlled and time-controlled manner, an inductive impedance having a tap which has a reverse-parallel thyristor circuit, by means of turn-on and turn-off signals from a monitoring device, or will completely switch out a real resistor. After continuous switching of a short-circuit and return of the voltage, a phase measuring device will determine the phase of the voltages of the generator groups and, in the event of a phase balance, turn on the main thyristors of the power circuit breaker via the monitoring device. <IMAGE>

Title: Mounting element
Inventor: FISCHER ARTUR DR
IPC: F16B13/08
Filed: 1982-04-30
Abstract: The invention relates to a mounting element, consisting of a radially overhanging retaining element for mounting objects having anchoring bolts whose anchoring part is formed by an expanding wedge which can be displaced with respect to the anchoring bolt and is inserted in a wall surface which is formed by a boundary surface running at right angles to the bolt longitudinal axis and a sliding surface which rises towards the front end of the bolt. In order to achieve a virtually slip-free anchorage of the anchoring bolt it is provided that a guide originating from the rear bolt end opens into the wall recess, in which guide an impact expanding pin is inserted which acts on the expanding wedge. Furthermore, the wall recess has a cross-section similar to a circular section and the expanding wedge has a profile matched to this cross-section in order to keep the cross-sectional weakening of the anchoring bolt small.
Patent DE-3217285-A1 (DE)
Title: Back-pressure valve
Inventor: ENDO HISAHI
IPC: F15B11/02
Filed: 1982-05-07
Abstract: A back-pressure valve (10), to be fitted in a fluid line between one of the fluid chambers of a double-acting hydraulic cylinder (12) and a control valve (18) and intended for receiving a fluid pressure produced by loading of the cylinder (12) when control valve (18) is closed, comprises a hollow valve body (32) which is encapsulated in a rigid housing (30) and has first and second radial inlet/outlet passages (54, 56) which are connected, via corresponding ports (40, 42) in the housing (30), with the control valve (18) or the cylinder (12). The valve body (32) accommodates a hollow valve spindle (34) and a stop element (36) which is in contact at the end face with the valve spindle (34) and can be displaced together with the latter. The valve spindle (34) and the stop element (36) define, in the valve body (32), a pilot-control pressure chamber (78) and a counter-pressure chamber (92), respectively, at the opposite ends of the valve body (32). The pilot-control pressure chamber (78) is connected via a restrictor bore (80) in the valve body (32) to a line (28) which connects the load-free fluid chamber of the cylinder (12) to the control valve (18). The counter-pressure chamber (92) is connected via a restrictor bore (94) in the stop element (36) to the interior of the valve spindle (34). The stop element (36) is preloaded by a compression-spring arrangement (38) and holds the valve spindle (34) in a position in which a non-return valve (24) fitted into the valve spindle (34) permits a fluid flow from the control valve (18) through the back-pressure valve (10) to the load-receiving fluid chamber of the cylinder (12) and prevents a return flow of the fluid in the opposite direction. However, if the pilot-control pressure chamber (78) is acted upon via the restrictor bore (80) by a fluid pressure arising in the line (28), the back-pressure valve (10) opens so that, when the cylinder (12) is retracted, fluid can flow off from the load-receiving chamber to the control valve (18). <IMAGE>

Title: Impeller blower
Inventor: FISCHER PETER
IPC: A01G13/02
Filed: 1982-09-03
Abstract: The invention relates to an impeller blower, especially for conveying and cutting up straw with a blower which can be driven via a tractor connection, an input for the material to be conveyed, a rigid ejection tube connected to the blower and a support frame on which the blower is mounted by means of a swivel pin which is essentially perpendicular to the ejection tube. Blowers of this kind are already known as stationary conveying devices for vertically conveying hay and straw in barns. In vineyards, hay and straw must be placed on the ground between the vines and between rows of vines, which are very close together, to prevent soil erosion. This has hitherto been carried out manually. The object of the invention is to produce a machine to perform the above task. According to the invention, this object is achieved by providing an impeller blower of the above type with a flexible connection tube attached to the end of the ejection tube pointing away from the blower, with a drive device to permit controllable swivelling of the blower about its swivel pin, with a moving mechanism mounted on the support frame and with a pole arranged on the support frame to permit coupling with a tractor.

Title: Circuit arrangement for controlling the recording of magnetic signals on a longitudinal control track of a video magnetic tape
Inventor: HORI TAKESHI
IPC: G11B27/024
Filed: 1982-11-22
Abstract: A control circuit arrangement for a video magnetic tape recording/replay device is connected to a fixed control head (11) for selectively changing the duty ratio of a control signal, which accompanies a recorded video signal and is the same signal which is used for controlling the servo functions for the head drum (29) and the various tape drive motors of the video magnetic-tape recording/replay device. The duty ratio of the control signal is normally 50%. However, the control circuit arrangement allows an operator to selectively change the duty ratio, for example to 30% in order to indicate that the section of the recorded video signal accompanied by the control signal is to be edited out, that is to say to be skipped when the video magnetic tape is played back. A duty-ratio detector (18), which is connected to the control head (11), detects the duty ratio of the reproduced control signal, and a system control device (19) automatically changes the operating mode of the device in order to fast forward sections of the video signal which are accompanied by a 30%-duty ratio control signal. <IMAGE>

Title: Control valve arrangement for lockup clutch
Inventor: SUGANO KAZUHIKO
IPC: F16H61/08
Filed: 1983-07-29
Abstract: The control valve arrangement comprises a lockup valve in order to control the engagement of a lockup clutch, and a lockup time control valve in order to control the supply of a first fluid medium pressure to the lockup valve. The first fluid medium pressure loads the lockup valve in order to bring about engagement of the lockup clutch. The lockup time control valve is moved in order to shut off the supply of the load oil pressure to the lockup valve when the second signal oil pressure rises beyond a first specific value, in order to allow the lockup valve to move into its first position, in order to trigger engagement of the lockup clutch. The lockup valve is moved out of its first position into its second position in order to bring about the re-engagement of the lockup clutch when the second signal oil pressure rises above a second specific value which is higher than the first specific value.
