Inventor: TAYLOR BRUCE F
IPC: D21G9/00
Filed: 1987-02-20
Abstract: Disclosed is a control system for controlling a web property profiling apparatus. The profiling apparatus includes a plurality of actuators (36) which are spaced across the web profiling apparatus. Each actuator (36) is controlled by an actuator driver (34) which is connected to a group of one or more actuators. A controller (40) sends a multiplexed control signal to the drivers (34) over a single coaxial link. The actuator drivers (34) demultiplex the transmitted signal, and the appropriate actuator driver corresponding to the location where the web property is to be altered accepts the signal and converts the signal to an analog form for operating the connected actuator(s) (36). Each actuator driver (34) is surrounded by a housing which environmentally protects the said driver. Such a housing would typically include an inner thin layer (54) of a high thermal conductivity material and an outer layer (55) of low conductivity material. The two layers are spaced apart from each other to form a chamber (56) therebetween and a fluid passes through the chamber to remove incoming and generated heat from the actuator drivers.

Abstract: The present invention is directed to an inverter-type resis­tance welding machine. A PWM inverter supplies high frequency primary voltage to a transformer. A microprocessor controls the PWM inverter by proportional-integral-deviation (PID) control through a PWM control unit. The microprocessor determines a feedforward operation amount which corresponds to a desired weld­ing current value before current is supplied to the welding elec­trodes. The time period for the calculation of an integral operation amount is effectively reduced to approximately zero by employing a calculated integral operation amount from a previous sampling.

An oil chamber (31) is defined between the pump cylinder (4) of the hydraulic pump and the motor cylinder (8) of the hydraulic motor. A common oil cooling unit (161) is connected through oil passages to the closed hydraulic circuit and the oil chamber (31) for cooling heated oil supplied therefrom. The common oil cooling unit effectively cools the oil from the two sources since the heat developed in the oil from the two sources generally varies inversely during different modes of operation.

Title: Powder-actuated nail setting tool
Inventor: GASSNER THEO
IPC: B25C1/18
Filed: 1987-02-11
Abstract: An explosive powder charge operated fastening member driving tool has a muzzle part which can be locked within and released and removed from the tool housing by rotational movement and axial movement relative to the housing. When the tool is not ready to be fired, a contact pressure sensor projects from the front end of the muzzle part. By pressing the sensor opposite to the firing direction it compresses a firing mechanism spring and the tool is ready to be fired. Stop elements are provided on the muzzle part and stop surfaces are located on the tool housing. When the muzzle part is in the unlocked condition, the stop elements can abut the stop surfaces and block the displacement of the contact pressure sensor preventing it from compressing the firing spring mechanism so that the driving tool cannot be placed in the ready-to-fire condition.

The directional control valve is operable between a first position in which one of the hydraulic actuators communicates with a first pressure line having the first line pressure, while the other actuator communicates with an atmosphere or a second pressure line having a second line pressurer, and a second position in which the above-indicated one actuator communicates with the atmosphere or second pressure line while the other actuator communicates with the first pressure line. The flow control valve controls rates of flows of the fluid to and from the actuators, in response to an operation of the directional control valve.

Abstract: The present invention provides a cylindrical alkaline battery comprising a positive electrode case of a cylindrical form having an opening at one end and accom­modating an electricity-generating element comprising a positive electrode, a negative electrode, a separator and an alkaline electrolytic solution, an insulating gasket provided at the opening of the positive electrode case, a bottom plate being the negative electrode terminal provided on the gasket, and a heat-shrinkable member such as shrink tube or the like covering the outer surface of the positive electrode case. In this battery, the opening end of the positive electrode case and the outer surface of the battery extending therefrom are covered with an electrical insulating film. The presence of the electrical insulating film prevents the exterior short circuit between the positive electrode case and the bottom plate being the negative electrode terminal which may occur when the metal material of the case opening is exposed by the peeling or abnormal shrinkage of the heat-shrinkable member. 
     The present invention also provides a cylind­rical alkaline battery comprising a reinforcing washer provided between the bottom plate being the negative electrode terminal and the gasket. In this battery, electric insulation is established between the bottom plate being the negative electrode terminal and the washer or between the gasket and the washer and the presence of   the electric insulation cuts off the possible electric reaction route forming a local cell and prevents the resultant leakage of the electrolytic solution.
