Abstract: CONTROLS FOR HYDRAULIC PERCUSSION DRILL               ABSTRACT OF THE DISCLOSURE      A control system for a hydraulic percussion rock drill and feed mechanism including a single constant power hydraulic pump for supplying pressure fluid to operate the feed mechanism, drill stem rotation motor, and the percussion hammer.  The drill feed, rotation and percussion functions are controlled by indi-vidual manually actuated pressure compensated valves.  Fluid pressure to the feed mechanism is controllable at one of two selectable pressures and is automatically reduced if fluid pressure to the drill stem rotation motor exceeds a predetermined limit.  The drill percussion blow intensity and frequency is controlled by a mechanism responsive to a fluid pressure signal which is automatically operated to provide for a high blow frequency and low blow intensity operating mode when the drill is retracted away from the workface.  The constant power hydraulic pump is provided with a control which will adjust the pump output to a partial displacement setting when the drill is being retracted away from the workface.  Alternatively, the pump control may be set to full displacement with a power limit and the drill percussion mechanism fluid supply may be automatically throttled when the drill is being retracted away from the workface.

Abstract: PRINTING BY MODULATION OF INK VISCOSITY Abstract of the Disclosure In a liquid ink printing system, ink is supplied to a reservoir at a predetermined pressure and viscosity the reservoir having one or more orifices of a predetermined size in a wall.  Electrical heating means is associated with each orifice, the heating means being controllable.  A bye-pass intercepts each orifice and connects to the reservoir.  With no heating, ink flows into the orifice and through the bye-pass.  On heating at an orifice, the ink viscosity is reduced and the flow increases, beyond the capacity of the bye-pass, and ink issues from the orifice to impinge on a sheet of paper or other material.                             -i-

Abstract: Abstract of the Disclosure An assembly of an electrical connector and several microcircuit modules is disclosed.  The electrical connector comprises a hollow prismatic housing of electrically insulating plastics material having a plurality of parallel electrical conductors extending along the inner faces of its walls, the conductors having portions extending from a common end of the housing for connection to conductors on a substrate.   The microcircuit modules are received in superposed relationship in the housing,  and each module comprises a body having a plurality of leads extending therefrom.   The leads are in contact with the conductors on the inner faces of the walls of the connector housing.  The conductors are all uninterrupted throughout their length  and at least some of the modules are allotted individually dedicated conductors. Each such module does not have loads connected to the conductors allotted to other  modules but has a lead connected to the individually dedicated conduc-tor.   The conductors which are not individually dedicated to particular modules serve for connections to all the modules in the connector.
