Title: Hydraulically actuated circuit breaker - has control valve whose element coacts with two valve seats of different dia.
IPC: H01H33/34
Filed: 1970-09-22
Abstract: The drive piston of the circuit breaker is continuously under pressure load in the OFF direction. It is brought under pressure, or relieved via a main control valve which hydraulically controlled. An advance control valve has a moving element whose one position blocks the hydraulic liquid flow to the main control valve, while releasing the outlet of the hydraulic liquid from this valve to a low pressure vessel. In its other position the valve opens the supply to the main control valve and stops the outlet to the low pressure vessel. The moving valve element (34) cooperates with two valve seats (35, 36) of different diameter in such manner that the resulting different force effects a hydraulic self-holding of the valve (33). If the drive piston is of differential type the different valve seats provide engagement of different piston surfaces.

Title: Resistance layer with isolated parallel resistance strips - uses different resistances trimmed by removing lowest resistance strip first
IPC: H01C17/24
Filed: 1970-11-06
Abstract: The resistance layer consists of several sections separated from one another by insulating sections and extending between two supply electrodes. The resistance layer sections are in the form of strips mounted on a common insulating substrate and the resistances of the strips (4, 5) increase, starting from the strip (4) at one end of the parallel array of strips and finishing at the strip at the opposite end. The resistance layer is trimmed to a given resistance by removing the lower resistance strips first. The strips are made to have different resistance by constructing them with different widths. The advantage lies in the simplicity and accuracy with which trimming takes place.

Title: Lubricating system for manually guided power tool - supplies oil from storage through reciprocating piston to crank drive
IPC: E02D3/068
Filed: 1971-04-29
Abstract: Lubricating system is used for the swivel drive of a manually guided power tool with reciprocating cutter. The power from the driving motor is transmitted via a pinion driven crank and connecting rod to a guide piston in turn connected with springs to the guide cylinder which acts as a tool holder. The piston pushes lubricating oil from the cylinder through the hollow piston rod to the crank drive. This lubricating system becomes immediately operational and its power absorption is negligible. The oil bath (7) is incorporated only in the lower part of the spring cylinder (1), and the oil surface comes into contact with the piston lower end at the end of the piston downstroke. The impact opens the nonreturn valve (8) and oil is pushed into the piston rod bore and to the crank drive.

Abstract: PROBLEM TO BE SOLVED: To improve the visual field angle characteristic and to improve the efficiency by disposing one common aperture with 4 pixels as a unit as the apertures of a counter electrode, disposing each pixel always opposite to the common aperture only at one point of its peripheral part and arranging the common apertures so as to orthogonally cross each other. SOLUTION: The opening 5 is arranged always between the adjacent pixels (electrodes) 1 and the 4 pixels have the one common elongated aperture. At this time, the (projection surface) of each pixel always partly faces (overlaps) the (projection surface) of the apertures when viewed from a direction where a user views a display surface but, on the other hand, the opposition of the plural apertures to the one pixel is averted. The adjacent 4 apertures are so arrayed as to intersect orthogonally with the adjacent apertures existing in their long side direction with a 4×4 pixel structure as a minimum unit. Namely, the array of repetitive patterns with the 4×4 pixel structure as a unit is obtained.

IPC: F16F9/50
Filed: 1982-05-18
Abstract: A shock absorber comprises a cylinder and a piston rod passing through at least one end of the cylinder. A piston unit is mounted on the piston rod and divides the cavity within the cylinder into two working chambers. A damping fluid is contained within the cylinder. The working chambers are interconnected across the piston unit by first and second branch flow passages arranged in parallel. First and second flow valves are associated with these first and second flow passages, respectively, and operate to dampen movement of the piston rod in at least one direction in dependency on the velocity of movement. The first branch passage flow valve is normally open and closes only when a predetermined velocity of movement is exceeded. The second branch passage flow valve is normally closed and opens only when the pressure differential between the working chambers exceeds a predetermined value. Closing of the first branch passage flow valve increases the damping effect. Opening of the second branch passage flow valve, which preferably occurs approximately at the same rod speed that the first valve closes, provides a further gradual increase in damping force upon further increase in rod velocity.
