Abstract: ABSTRACT OF THE DISCLOSURE        A process for producing a floating-type magnetic head  comprising a head core and a slider by forming a glass layer over a core chip to cover the portion thereof to be opposed to a magnetic recording medium, and there-after fitting the core chip into a core groove in a slider chip.  The core chip is fittable into the groove without the likelihood of causing damage to the medium opposed portion since this portion is covered with the glass layer.  The glass layer is melted to bond the core chip to the slider chip, and the assembly is machined to form a medium opposed face to complete the magnetic head.

Abstract: APPARATUS AND METHOD FOR PROTECTING THE CONTACTS    OF AN ELECTRICAL SWITCH FROM CURRENT SURGES             Abstract of the Disclosure The contacts of an electrical switch, such as a magnetic contact reed switch or a magnetic contact reed relay used in a burglar alarm system, are protected from being fused together by transient current surges.  This protection is accomplished by providing a normally nonconductive shunting path in parallel with the switch.  The shunting path includes a voltage responsive device which is biased to conduction in response to a current surge to thereby complete the shunting path and allow the current surge to bypass the switch.

Abstract: ABSTRACT    In a process of producing a keyboard switch, a continuous track of a metal foil is machined into two metallic terminal components constituting links between two carrier strips.  A base housing component is cast from a high temperature resistant material around the terminals and is connected to the carrier strips through two tags protruding outwards from opposite, outer side surfaces of the base housing component.  In an inner recess of the base housing component a domed metal disc having an accoustically damping coating on the convex side surface thereof, an elastically compressible rubber component and a push button are arranged.  On top of the base housing component, a top housing component preferably made from the same high temperature resistant plastics material is arranged, within the recess of the base housing component, the terminals define electric contacts with which the domed metal disc co-operates.  The terminals are separated from the carrier strips and bent into the configuration of pins of an electronic keyboard switch, and the keyboard switch is still connected through the tags to the carrier strips transferred to a test stand, in which the keyboard switch is tested.  Provided the keyboard switch is identified as a properly functioning keyboard switch, the tags are separated from the base housing component.

Abstract: Abstract The invention relates to a device for screening pulp, comprising a screen drum (2) provided with holes for the passage of an accepted pulp fraction therethrough; and a blade (10) for a screening device. The device comprises straight blades (10) wiping the surface of the screen drum (2) and extending in parallel with the axis of the screen drum (2). Reject which does not pass through the screen drum (2) is removed through a reject discharge opening (5) at the other end of the screen drum. For transferring the reject from the sur-face of the screen drum (2) to the reject discharge end, the surface of the blades (10) is on the screen drum side provided with grooves (11) so inclined that the front end of the groove (11) is closer to the pulp input than the rearmost end of the same groove (11).          Thereby each groove (11) in the blades (10) causes the reject to be transferred towards the reject discharge opening (5).

Abstract: A B S T R A C T                   METHOD AND APPARATUS FOR PLACING   A CEMENT LINING IN A BOREHOLE       A cement lining is placed in a borehole using a cementing apparatus including a centralized stinger which is suspended from a cement injection tubing. In use a cement slurry is introduced into the annular space surrounding the tubing and stinger and after subsequently filling the interior of the tubing and stinger with mud the apparatus is pulled thereby leaving in the borehole a cement plug with an open or soft core. The centralization of the stinger ensures that after hardening of the cement a cement layer of a constant thickness is created alongside the borehole wall.

Abstract: A control system and method for chemical injectors includes a controller which outputs multiple feed set point signals and associated driver signals, each set point signal defining  a  desired  injection capacity for  a  chemical injector  and the  associated driver  designation  signal designating the injector to receive the set point signal.  A driver assembly is associated with each injector.   The driver assembly receives a capacity signal from the injector which defines the volumetric injection capacity of the injector, compares the capacity signal to the feed set point signal, and outputs a drive signal to adjust the volumetric injection capacity of the injector.  An adjustment assembly is provided for receiving the drive signal and positioning a stop to limit the reciprocal motion of the piston of the injector,  thereby  adjusting  the  volumetric  injection capacity of the injector.   The injectors inject into a common carrier fluid,  such as irrigation water,  and the carrier fluid, through a carrier fluid flow operated valve, is  also used to  reciprocate the injector pistons.   A disabling  assembly  is  provided to disable  the driver assemblies when the pistons of the injectors are forced against the stops.

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a half-slotted container body and lid, each made from a blank of corrugated paperboard.  The lid blank has an additional score to provide a fold-line around the perimeter of the side and end panels at approximately one-half of the depth.  This score line defines inner and outer panels of the lid's perimeter side and end walls.  Where this fold-line intersects each of the panel score lines defining the ends of the side and end panels, there are two diagonal scores which radiate from that point in opposite directions extending to the free edge of the inner panels.     When the lid is set up, the top flaps are folded inwardly and secured to form a top of the lid, and the inner panels are folded inwardly hinged at the four corners by the diagonal scores.  The inner panels are pushed in at the interior four corners of the lid locking the inner panels along the outer panels to provide a two-ply perimeter wall of the lid.  The resulting inward bulge of the inner panels of the lid create a secure lock of the lid on the body and provide support for the sides of the body against outwardly bulging under load.     The continuous two-ply construction of the sides of the lid provide channeling space between adjoining containers in a stacked pallet load to enhance uniform air flow and cooling of produce, such as bananas and fruits, packed in the containers.
