Patent number: 4108564Abstract: A drilling device for workpieces of different sizes is disclosed herein. The drilling device includes a tool carrier supported by a carriage for reciprocable movement thereon along a path and the carriage is also reciprocable along the path. The carriage is biased to a predetermined starting position. When a tool on the tool carrier engages the workpiece, the carriage is moved in the opposite direction and engages a switch to reduce the feed speed of the tool carrier for a short period of time during which the carriage engages a stop to define a fixed drilling position. Upon completion of the drilling operation, a biasing spring moves the carriage in the drilling direction beyond the starting position to actuate a switch and return the tool carrier to a starting position while the carriage is also returned to the starting position.Type: GrantFiled: March 15, 1977Date of Patent: August 22, 1978Assignee: Werner PeddinghausInventors: Werner Peddinghaus, Ludwig Regenbrecht

Patent number: 4107071Abstract: Microcapsules having a capsule core material surrounded by a relatively impermeable, densified protective wall and a method of producing such microcapsules are disclosed. To produce the microcapsules, an agitated system is provided including a liquid vehicle as a major component of the system and constituting a continuous first phase of the system. A plurality of discrete capsule core material entities are dispersed in the liquid vehicle and constitute a discontinuous second phase. A film-forming, cross-linkable, polymeric base material is also present in the liquid vehicle and, upon induction of phase separation within the agitated system, forms a sheath about the capsule core material entities. The formed sheath also contains entrapped liquid vehicle; however, a major portion of the entrapped liquid vehicle is subsequently extracted from the sheath, and the resulting densified polymeric base material in the sheath is then cross-linked to form a densified protective wall around the capsule core material.Type: GrantFiled: February 16, 1977Date of Patent: August 15, 1978Assignee: Capsulated Systems, Inc.Inventor: Robert G. Bayless

Patent number: 4106631Abstract: A multisection crane boom having a fly and jib assembly attachable thereto is disclosed herein. The fly section and jib section of the assembly are pivotally interconnected at adjacent ends through a freely pivoted link so that the jib section can be pivoted from the stored position extending generally parallel and below the fly section to a usable position wherein the longitudinal axes of the two sections are aligned with each other or coincident at the interconnected ends. Cable means are utilized for holding the jib section in an extended position on the fly section and the cable means are capable of having the jib in end-to-end or angular relation with respect to the fly section. The fly section also has a lug thereon which prevents attachment of the cable means when the fly section is at an angular position with respect to the main boom. The fly section is connected to the boom in a unique fashion which eliminates the need for cables to hold the fly section in a plurality of positions.Type: GrantFiled: February 18, 1977Date of Patent: August 15, 1978Assignee: J. I. Case CompanyInventor: Richard W. Lundy

Patent number: 4106818Abstract: A powered assist braking system having a pressurized fluid source which also supplies fluid to the steering system of a vehicle is disclosed herein. The braking system includes left and right-hand brake actuators that cooperate with a power brake valve and the actuators are designed so that, when actuated, hydraulic fluid is trapped in a chamber and this fluid is supplied to actuate the brake while the pressurized fluid source assists in pressurizing the trapped fluid. The power brake valve has a pressure release assembly incorporated therein which controls the maximum pressure of the inlet fluid and also controls the flow of fluid to the steering system. The system also is designed to equalize the pressure of the fluid when both brakes are simultaneously actuated.Type: GrantFiled: May 27, 1977Date of Patent: August 15, 1978Assignee: J. I.

Patent number: 4103561Abstract: A method and apparatus for reducing shock loads to an operator of a vehicle during turning movement is disclosed herein. The method consists of increasing the mass of an actuator connected to a control element which controls flow of hydraulic fluid to a fluid motor that produces turning movement for the vehicle. The increased mass is spaced from the fixed rotational axis for the actuator which results in an increased moment of inertia for the actuator that resists acceleration and deceleration of the actuator thereby resisting rapid changes in turning movements for the vehicle.Type: GrantFiled: March 31, 1977Date of Patent: August 1, 1978Assignee: J. I. Case CompanyInventor: Donald C. Baker
