Abstract: ABSTRACT      An hydraulic system:  a power assisted vehicle steering system which includes such an hydraulic system and a method of alleviating noise in an hydraulic system. The hydraulic system as applied to a vehicle steering gear (1) has an open centre valve (3) which directs hydraulic fluid under pressure derived from a pump (12) and in response to a steering manoeuvre through a shaft (4) to a servo motor of the gear (1).   Downstream of the open centre valve (3) is a restrictor (8) through which hydraulic fluid from the valve (3) passes to a reservoir (11).   The restriction effected by the restrictor (8) to fluid flow from the valve (3) to the reservoir is variable to provide a throttling action and a back pressure in the line (6) to alleviate noise in the valve (3).   The restrictor (8) is preferably in the form of a spool which is subjected to a pressure.

Abstract: ABSTRACT    In ultrasonic examination of objects - particularly of organs in the human body - it is often valuable to know the variation, within the object, of the velocity of propagation of ultrasound.  Previously, determination of variations in the velocity of propagation of sound has been effected using computed tomography image reconstruction techniques with data obtained from ultrasonic transmission between transducers positioned on opposite sides of the object.  With objects containing barriers to ultra-sound (such as bones or gas-filled regions), data for these techniques cannot be obtained.  In this specification, a technique is disclosed for measuring variation of the velocity of propagation of ultra-sound in objects by image reconstruction using reflected echoes of pulses of ultrasound.  This new technique involves transmitting pulses of ultrasonic energy into the object from a plurality of spaced locations, obtaining echoes of each pulse from a predetermined point within the object, and using the shift in echoes from that point for the various input pulses to obtain information representative of the divergences of velocity of propagation of ultrasound within the object.

Abstract: Abstract of the Disclosure Apparatus for assembling covered buttons in which a first die assembly including a first punch carrying a first sleeve which sequentially receives a piece of covering material and the button shell with its flange extending toward the open end of the sleeve.  A second assembly including a second sleeve having a bore one end of which is formed with a first cam surface extending axially inwardly of the above.  The second sleeve is spring loaded to an extended position on a supporting post having a centrally located button back fastener receiving cavity in the end thereof with a second cam surface extending inwardly from the outer edge of the end to the bottom of a recess surrounding the cavity.  An annular boss at the inner edge of the recess around the cavity is elevated to allow the material and the shell flange to curl inwardly under the button back.  In the retracted position of the second sleeve on the post, the second cam surface forms a continuation of the first.  In operation, when the first assembly carrying the covering piece and the shell moves toward the second assembly, the first sleeve stops against the spring loaded bottom sleeve and the punch continues forcing the material down so that the material is tucked inward by the beveled or curved surface of the second sleeve.  Upon continued relative movement of the assemblies, the shell flange acts on the cam surface of the second sleeve to force the sleeve to its retracted position and the shell flange is moved inwardly of the back wall under the continued action of the first post, the extent of the inward movement of the shell flange being determined by the thickness of the material of the covering piece, as well as the height of the shell and the type of back used.

Abstract: HYDRAULICALLY OPERATED TRANSMISSION CONTROL              Abstract of the Disclosure A hydraulically operated control arrangement for a transmis-sion includes a spring-loaded pressure regulating valve which slides into a position to cut off an exit chamber for hydraulic fluid from an input chamber for pressurized hydraulic fluid so as to route the incoming hydraulic fluid exclusively to the transmis-sion for various control and lubricating functions when hydraulic fluid pressure in the input chamber falls below a first threshold value.  Hydraulic fluid applied to the input chamber continues to feed a first plurality of functions within the transmission via the input chamber and a second plurality of functions in the transmission via an intermediate chamber disposed between the input and exit chambers and in communication with the pressure regulating valve until such time as the hydraulic fluid pressure at the input chamber drops below a second threshold value so as to permit the pressure regulating valve to cut off the interme-diate chamber from the input chamber.  If the hydraulic fluid pressure within the input chamber falls a sufficient amount, the pressure regulating valve engages a contact which completes an electrical circuit to a low hydraulic fluid pressure warning light.  A hydraulically operated detent arrangement coupled to the input chamber and which normally holds a power takeoff control lever in an engaged or on position releases the control lever upon loss of hydraulic fluid pressure to allow a power takeoff control valve within the control arrangement and which also re-sponds to the lost hydraulic fluid pressure to move the control lever from the engaged or on position to a disengaged or off position.  A highlow control valve which is coupled to a control lever for a planetary section of the transmission and which provides hydraulic fluid from the input chamber to the planetary section when in a high position cooperates with a second valve coupled to the input chamber and sensitive to hydraulic fluid pressure therein to cause the high-low control valve and the associated control lever to be pulled into a low position and thereby cut off the supply of hydraulic fluid to the planetary section when hydraulic fluid pressure within the input chamber drops below a predetermined value.

Abstract: ABSTRACT OF THE DISCLOSURE This invention provides a spinning process for producing a spun stream comprising a plurality of separate spun interfaces from a given single interface between different polymers in a supply stream. The given interface extends generally parallel to the direction of the supply stream, and the process is characterized by the steps of passing the supply stream through a spinneret orifice which is effectively in the form of an elongated slot. The cross-sectional shape of the orifice and the given interface are selected and located with respect to each other such that a first portion of the given interface passes through and extends transversely across the width of the slot at a first location along the length of the slot and a second portion of the given interface passes through and extends transversely across the width. of the slot at a second location along the length. of the slot. The spun stream issuing from the slot is then solidified. The process of this invention overcomes disadvantages involved in prior art processes which entail a considerable complexity in the conjugation plates prior to the spinneret itself; with the present invention, the conjugation plates upstream of the spinneret can be considerably simplified by appropriate design of the spinneret orifice.

Abstract: A B S T R A C T      A method and a meter for measuring the quantity of heat abstracted from a circulating flow of liquid by a consumption unit. Indirect measurement of the volume flow rate of the liquid is made, while maintaining a sub heat flow (? shunt) from or to the main heat flow transported by the flow of liquid and measuring the temperature at some points by means of temperature sensors (4). The volume flow rate of the flow of liquid is determined on the basis of the flow rate dependent heat transfer in the boundary layer (7) of the flow of liquid at the location, where the sub heat flow (? shunt) leaves or enters, by determi-ning the temperature differential ( .DELTA. Ti, b) across the boundary layer, and the sub heat flow (? shunt) passing through said boundary layer (7). At least one absolute temperature of the flow of liquid is measured for correcting the temperature depen-dency of the material constants of the liquid involved in said determination of the volume flow rate.
