Patent EP-0089447-A3 (EP)
IPC: F15B13/042
Filed: 1982-03-22
Abstract: For special employ in hydraulic contrivances such as: 
distributors, driving cylinders and for the hydraulic regula­
tion of pumps and motors with changing capacity, the device 
permits an exact proportionality between shifting of the 
control lever and the pressure wanted by the users. In 
stationary position of the lever, the delivery ducts to the 
users are connected with a drain duct by means of an 
insertion fitted in the device body.  
     The lever fulcrum is fitted on a head lever bearer 
supported on a wrist joint. By shifting the lever, a pusher is 
driven which presses a supporting spring giving rise to a 
displacement downwards of a small rod. In this way, through 
an annular chamber, the feeding pressure is set into 
communication with a bore leading to one of the users. This 
is possible because the annular chamber is communicating 
through a radial bore with two axial bores leading to another 
annular chamber and allows in this way to get a pressure in 
the use zone lower than the feeding one and proportional to 
the span opened by the small rod.  
     To the span reduction a spring is opposing, the shiffness 
of which is proportional to the lever displacement which is 
acting on the pusher. In the device, similar operation 
departments with rod are foreseen proportionally to the 
number of the use ducts which can be acted on by changing 
the lever movement.

Title: Pipe coupling
IPC: F16L21/00
Filed: 1986-05-15
Abstract: A pipe coupling for coupling together pipe ends of pipes to be interconnected comprises a clampable housing approximately in the shape of a tightening clamp or collar for being clamped about the pipe ends such that tightening of the clampable housing causes the housing to contract or draw together around the pipes to be connected. The housing possesses annular or ring-shaped, inwardly flexed flanges at its end faces. A sealing gasket made from an elastic material such as synthetic rubber is enclosed in the housing and possesses a substantially C-shaped axial cross-sectional configuration. Clamping rings provided on the inner sides of the sealing gasket are capable of being reduced in diameter and supported in axial direction on the housing. These clamping rings are provided on their inner surfaces with claws or claw-like elements. To limit the penetration depth of these claws, especially in soft pipe material, the substantially cylindrical clamping rings are supported in the housing by their outer jacket surfaces on the inner edges of the housing flanges and by respective stop members as well as respective substantially conical spring rings. The claws of the clamping rings comprise teeth protruding inwardly from the inner jacket surfaces of the clamping rings towards the centers of the pipe ends. These teeth possess convex backs arched away from the center portion of the pipe coupling and substantially flat front surfaces which extend into clamping ring recesses located substantially directly before these front surfaces.

Abstract: A fastener driving tool has a motor (24) (Fig. 1) 
driven energy storing flywheel (26) and a reciprocating 
fastener driving ram (44). The flywheel has a metal 
peripheral surface that selectively engages a metal 
surface of the ram in order to drive the ram into 
engagement with a fastener (104) to be driven into a 
workpiece. Selective engagement occurs upon operation 
of a solenoid (84) to propel a thicker portion of the 
ram into the nip of an idler roller (28) and the fly­
wheel closed together by movement of a safety yoke 
(23) engaging the workpiece (not shown), the movement 
being transferred to the roller (28)  via  a toggle 
linkage (64, 68). An elastic cord (52) returns the ram 
to a retracted position when the ram is disengaged by 
the flywheel, and a pair of elastic bumpers (48, 50) 
are employed to limit the travel of the ram in the 
direction of the retracted position and the direction 
of the fastener engaging position. The ram, bumpers 
and cords form a subassembly (48) that permits the ram, 
cord and bumpers to be removed from the fastener as a 
unit. The cord (52) is made relatively long to reduce 
the amount of stretch per unit length applied to the 
cord thereby to increase the life of the cord. The 
motor (224) (see Fig. 14) and flywheel may be rotated 
in opposite directions to reduce precessional forces 
but in any event, the motor is mounted to the rear 
of the tool and drives the flywheel through a flexible 
drive belt (30, 230) to provide for a well balanced 
tool.

Abstract: In a process for recovering zinc from zinc sulphide 
concentrates, the concentrate is roasted in an oxygen 
deficient atmosphere so as to retard ferrite formation in the 
temperature range of 600°C to 1000°C. In one embodiment 
the calcine produced is subjected to physical separation 
processes, the unreacted zinc sulphides are then dead 
roasted separately, and the separated iron containing frac­
tion is treated for further zinc recovery.  
     In another embodiment the unreacted sulphides in the 
calcine are separated by physical and or chemical means and 
returned to the partial roasting step; and the separated 
oxidic fraction either as solids or in a solution, are treated for 
zinc recovery, and iron disposal. Undesirable sulphides are 
bled off from the processing circuit as required.

Title: Programmable logic device
IPC: H03K19/177
Filed: 1986-11-28
Abstract: A device having a number of general registers each allocated an input<sup>/</sup>output port and a number internal "buried" state registers. A user-controlled signal permits observation of the contents of the buried state registers at an input/output port although these registers are not allocated an input! output port. Each register is connected to a logic circuit internal to the device by a dedicated feedback path so that all registers can be used to specify states in a state machine sequencer. A fuse-programmable XOR gate permits a user to control generation of signals at the ports by permitting enabling and disabling of an inverting output buffer. Asynchronous reset and synchronous preset of the registers is prov ided. In addition to the dedicated feedback paths, programmable feedback paths are provided. An output inverter can selectably be enabled from internal signals or from an external pin. The input/output circuit can be deployed in banks, each bank selectably receiving the same or a different clock. The registers can be preloaded via an internally-generated signal or from the external pins. In an alternative embodiment, a programmable AND array and a pair of programmable OR arrays, each serving one of the banks, provides a flexible programmable logic array device with observable buried states.

Abstract: A decoupling capacitor and method of forming the 
same, and a novel multilayer ceramic capacitor chip con­
struction is presented. In the method, a conductor (14) 
having a lead (18) connected thereto is formed from a 
continuous strip of electrically conductive material (10), the 
strip having opposing planar surfaces. A dummy lead (20), 
associated with the conductor (14), but isolated therefrom, is 
also formed from the strip (10). Two such strips (10, 10′) (lead 
frames) are then spaced apart in a parallel orientation and a 
strip of insulating material (28) having a plurality of openings 
or windows (34) therein is sandwiched betwen the two lead 
frames (10, 10′). A novel multi-layer ceramic capacitor chip 
(38) having conductive electrodes (46′, 44′) on the top and 
bottom surfaces thereof is inserted into each window (34) so 
that the top and bottom electrodes (46′, 44′) respectively 
contact a conductor from each lead frame. Preferably, 
conductive epoxy is used to effect an electrical and mecha­
nical connection between the capacitor chip electrodes and 
the lead frame conductors (14, 14′). Thereafter, a top strip 
(30) of outer insulating material is positioned across from 
one opposing surface of a first conductive strip (10) and a 
bottom strip (32) of outer insulating material is positioned on 
another opposing surface of a second conductive strip (10′). 
The top and bottom outer insulating layers (30, 32) sand­
wiching the pair of parallel conductive strips (19, 10′) are 
then heat tacked and hot press laminated to form a 
continuous strip of laminated material. Finally, the now 
sealed and laminated decoupling capacitor is severed from 
the pair of lead frames. The decoupling capacitor of the 
present invention will thus be both hermetically sealed and 
automatically insertable for use in conjunction with inte­
grated circuit DIP inserter devices.
