Patent number: 4879963Abstract: A sport fishing seat for fishing boats is provided with a saddle seat and a foot pedal assembly. In one version the foot pedal assembly pivots of the seat support which enables a fisherman to utilize the leg muscles while reeling in a game fish. The foot pedal assembly in that version includes a tubular post which receives the butt end of the fishing rod while at the lower end thereof the pedal portion may be engaged by the feet of the fisherman. This assembly is pivotally mounted on a bracket means extending laterally outward from underneath the seat proper and this enables the fisherman to utilize his leg muscles to greater advantage in playing and landing a game fish. In all saddle seat versions the fisherman has his legs on either side of the saddle seat and is a convenient arrangement for small boats, little space being taken up by the seat and pedestal.Type: GrantFiled: January 9, 1989Date of Patent: November 14, 1989Assignee: Robert N.

Patent number: 4879593Abstract: After sawtooth wave deflection signals are corrected in a summing circuit for position, magnitude, shape, they are keyed by a blanking circuit, within a blanking interval of the video signal, for briefly inserting a low-voltage reference potential. This is done before the corrected deflection signals are capacitively coupled to high voltage amplifying circuits supplying an electrostatic deflection plate of a camera tube. The high voltage amplifiers are equipped with a clamping circuit timed to clamp the high voltage output to a high voltage reference potential during substantially the same intervals in which the low voltage wave is keyed for insertion of the low voltage reference potential. The vertical deflection signals are keyed at low voltage and clamped at high voltage at the vertical scanning frequency. The horizontal deflection signals may be keyed and clamped either at the horizontal scanning frequency or, for saving of expense and equipment, at the vertical scanning frequency.Type: GrantFiled: March 4, 1988Date of Patent: November 7, 1989Assignee: Robert Bosch GmbHInventors: Harald Eschelbach, Wolfram Klemmer

Patent number: 4878470Abstract: A device for actuating a butterfly throttle valve of an internal combustion engine includes a hydraulic setting member for rotating a shaft of the throttle valve. The hydraulic setting member is driven by a branch flow of fuel delivered by a fuel pump and acting as pressure medium. The branch flow passes through a series of connection of adjustable throttles connected in a hydraulic bridge circuit. The throttles are adjusted by a regulating signal corresponding to the difference between an actual position signal delivered by a position sensor coupled to the throttle valve, and a desired position sensor coupled for example to a gas pedal of the motor vehicle.Type: GrantFiled: October 13, 1988Date of Patent: November 7, 1989Assignee: Robert Bosch GmbHInventors: Rainer Burkel, Kurt Engelsdorf, Rolf Gawlik, Karl-Heinz Hagele

Patent number: 4878519Abstract: An accumulator comprises a cylinder formed with a substantially closed chamber and a piston formed with a small-diameter central region and a pair of large-diameter end regions flanking the central region and each formed with an outwardly open annular groove. This piston subdivides the chamber into a gas compartment at one of the end regions, a liquid compartment at the other end region, and an annular charging compartment surrounding the central region. The piston is displaceable in the cylinder to oppositely vary the volumes of the gas and liquid compartments. Respective gas and liquid seals are engaged in the grooves between the gas- and liquid-compartment end regions of the piston and the cylinder and are both constructed to inhibit fluid flow from the respective gas and liquid compartments into the charging compartment.Type: GrantFiled: August 11, 1988Date of Patent: November 7, 1989Assignee: Robert Bosch GmbHInventors: Josef Berding, Hannes Bertling, Thomas Lees, Carsten Pabst

Patent number: 4876845Abstract: A self-propelled powered mower (11) and a towed trailing mower (12) are connected together by an adjustable height connector assembly (13). When the powered mower begins to move through a turn, the alignment detector cylinder (60) is required to retract due to the pivoting of the draw bar (21) and its angled support arm about the vertical pivot pin (50) of the connector assembly (13) (FIG. 3). The fluid displaced from alignment detector cylinder (60) causes the rod (56) to extend from height adjustment cylinder (55), thereby raising the forward portion of the towed mower.Type: GrantFiled: April 12, 1989Date of Patent: October 31, 1989Assignee: Robert M. TorrasInventor: James D. Sturgill

Patent number: 4873956Abstract: A fuel injection pump for internal combustion engines having an electromagnetic final control element, which in order to adjust the end or onset of injection engages a control slide, located in the pump interior. Via a control shaft, the final control element chamber is hermetically sealed off from the pump interior in order to keep water contained in the fuel from reaching current-carrying parts of the final control element. As a result, fluid communication exists only via the bearing gap of the slide bearing of the control shaft and the bearing gap functions as a throttle. The throttle forms a water separator, which further reduces the concentration of water in the already small quantity of fuel reaching the final control element chamber through the throttle.Type: GrantFiled: December 17, 1987Date of Patent: October 17, 1989Assignee: Robert Bosch GmbHInventors: Wolfgang Fehlmann, Gerald Hofer, Dieter Junger, Anton Karle, Helmut Laufer

Patent number: 4873988Abstract: To provide for adjusted positioning of a pulse sensor (50) against the selected toe of a patient, while the patient is relaxed, and without applying substantial pressure of the sensor against the toe, a base plate is formed with a depression to receive the heel of the foot of the user, and a support element (20) is adjustably positioned on a pair of parallel vertically extending posts (17, 18), projecting from the base plate. The support element is a transverse structure, slidable on the posts, and having a shaft (30) to which a bail (42) is attached. The pulse sensor (50) is mounted on the horizontal portion (48) of the bail, and is slidable along and rotatable about the portion (48). In addition, the bail (42) is slidable sideways (B) with respect to the foot of the user, i.e. across the toes, movable back and forth with respect to the toe to be tested while the pulse sensor (50) is retained against the toe by a spring (34) biasing the shaft, and hence the bail, towards the toe.Type: GrantFiled: May 16, 1988Date of Patent: October 17, 1989Assignee: Robert Bosch GmbHInventors: Karl-Heinz Affeldt, Ulrich Hantel

Patent number: 4875106Abstract: A finite impulse response filter is used for providing substitute sample values for erroneous sample values and isolated erroneous sample values appear. When sample values needed for contributing to the concealment of an erroneous value by the filter are also marked as erroneous, they are replaced by the corresponding sample value in the preceding television line, as represented by the output of the FIR filter, delayed by one line. In the case of the first line, the last error-free sample value in the same line, or an average of neighboring sample values, is used as an auxiliary value for calculation of a replacement value in the FIR filter.Type: GrantFiled: May 24, 1988Date of Patent: October 17, 1989Assignee: Robert Bosch GmbHInventor: Jurgen Heitman

Patent number: 4872732Abstract: The proposed vehicle brake system has wheel brakes, a master brake cylinder, an auxiliary pressure source, and a brake booster supplied from it for actuating the master brake cylinder, as well as an apparatus capable of preventing the danger of skidding and limiting drive slip at driven wheels. To prevent the danger of skidding, valves disposed between the master brake cylinder and the wheel brakes are provided by means of which the wheel brakes can be disconnected from the master brake cylinder and connected to a pressure fluid supply container to reduce the brake pressure. For replacing the quantities of pressure fluid diverted into this pressure fluid supply container, the valves are connected to the brake booster. To enable limiting drive slip at driven wheels at little expense for additional valves, valves embodied as 2/2-way valves are connected between the wheel brakes of driven wheels and their associated valves also communicate with the auxiliary pressure source.Type: GrantFiled: October 7, 1988Date of Patent: October 10, 1989Assignee: Robert Bosch GmbHInventor: Alwin Stegmaier
