Patent SE-7407132-L (SE)
Inventor: FASSBENDER R
IPC: B62D5/32
Filed: 1974-05-29
Abstract: In systems using a main pump and a reserve pump where it is essential that pressure feed to a consumer unit, e.g., a vehicle booster steering device, be available in the event of failure of the main pump, the invention provides quick shifting to a reserve pump. The effect is achieved in two embodiments of the invention by means of a valve which is spring biased to a closed flow condition of the main stream from a main pump, but opening the main flow responsive to consumer unit demand, while, however, permitting continuous reserve pump flow to reach the consumer unit prior to such opening. A pilot stream from the main pump establishes a pressure differential on the valve to control response to main pump failure for cutting in the reserve pump. The pilot flow is through a pressure chamber means in which a drop in pressure due either to unit demand or main pump failure is effective to cause valve actuation for main flow opening, or valve opening for reserve pump flow. An important feature of the invention resides in the fact that the pressure drop is achieved either by loss of main pump pressure or reduction in discharge rate, e.g., due to a slipping drive belt of the main pump.

Abstract: A process for the uninterrupted manufacture of plastic film tubing by the blowing up of a continuous film tubing by means of an extruder-injector, including an inner cooling of the extruded film tubing using a gaseous cooling means initially in a liquified condition introduced inside the film tubing. The cooling medium is converted into its vaporous or gaseous condition through evaporation before being purged. The cooling medium is introduced inside the film tubing in its liquified state in such a manner that up to a reversing point located above the nozzle tip of the device, an upward coolant stream occurs in the center of the inner space of the tubing, from which stream liquid and/or solid coolant particles are carried and kept in suspension. At the reversing point the coolant stream fans out radially after which the cooling medium falls back down in an opposite direction along the wall of the film tubing toward the coolant outlet. The reversing point is made sufficiently high so that the liquid and/or solid coolant particles carried by the stream can evaporate before the coolant medium reaches an area of the film tubing which lies below the frost line in the tubing so that such an area only comes in contact with the vaporous and/or gaseous falling coolant stream.

Abstract: 1530639 Radar; aerials HUGHES AIRCRAFT CO 2 March 1976 [24 March 1975] 08353/76 Headings H4D and H4A The radar system described in Specification No. 1,405,241 is modified to allow provision for improving the focus of the receiving antenna for targets at close ranges where the curvature of the incident wavefront cannot be neglected, by varying the frequency of the local oscillator in a predetermined manner, for a time, after transmission of a pulse, corresponding to a predetermined number of range bins as far as a maximum range for which focus compensation is provided and thereafter holding the L.O. frequency constant, the distribution of path lengths from the L.O. to the elements of the aerial array and hence the phasing of each element being arranged to follow a quadratic function. The phasing of the elements is approximated to the correct curve for an incident circular wavefront which is kt [1 - cos <SP>x</SP>/ KI ] where t is the time variable, x is the distance from the array centre and k is a constant, by using the first term x<SP>2</SP>/2kt, of the Taylor Series expansion of the aforementioned expression which latter term is a separable function and is constituted in the invention by varying the L.O. frequency as <SP>1</SP>/ l  and varying the phase distribution of the signals through the variously lengthed element feeds as the quadrattic function x<SP>2</SP>. Hence the phase distribution along the antenna elements varies parabolically to approximate a circle whereby the phase shifters along the array focus on a plane wave and, as the local oscillator frequency decreases as a function of '/, the array focuses on a steadily increasing range. In Fig. 13, a pulse 520 is transmitted and the receiver is activated, the L.O. frequency being f 2 , e.g. 1 microsecond later. The L.O. frequency then decreases as per curve 522 until it reaches a second frequency, which is then held constant for the rest of the range and corresponds to reception of a plane wave along the array until the time of maximum range. This process is then repeated at the system p.r.f. The phase distribution produced by the arrangement of the feed lines 159 in Fig. 3a, may be produced by having the branch points nonsymmetrically placed to provide the parabolic path length variation.

Abstract: The hub supports a cutting tool and is mounted on a shaft of a cutting-out machine. The hub has a ground face (15) perpendicular to the axis of the hub and a cylindrical part (18) which serves to centre an annular cutter (3) whose ground face (16) must be kept in contact with the ground face (15). The hub has a radial bore (14) with a radial inlet hole (19). An annular groove (121) communicates with the inlet hole (19) and helical grooves (22, 23) extend from the annular groove (121) and end in smooth parts (24, 25) before reaching the end of the bore. In order to adjust the axial position of the hub on the shaft, fluid under high pressure is introduced through the radial hole (19) in order to expand the hub. The pressure of the fluid acts uniformly all around the interface of the hub and the shaft, so that an asymmetric distortion of the hub is avoided and so that the entire periphery of the cutting edge of the cutter remains substantially within a plane perpendicular to the axis of the shaft. <IMAGE>

Abstract: The invention is directed to a supervisory circuit for a control system of the type having a plurality of redundant input channels and a single output channel. More specifically, the invention is directed to a supervisory circuit for a two-channel redundant control system that provides reliability approaching that of a three-channel system. The supervisory circuit operates on the assumption that the majority of control circuit failures are catastrophic. The supervisory circuit includes a channel select circuit that receives the outputs of both of the identical control circuits and determines the faulted channel. Determination of the faulted channel is accomplished by a two-step comparison. In the first step, the outputs of both channels are compared with a previously stored output, or average of previous outputs. In the second step, signals representative of the absolute difference between each channel output and the stored output are compared. The polarity of the output of the second comparison determines the faulted channel. Normally, a manual channel select switch determines which channel is used as the output of the control system. In one embodiment of the invention an independent trip circuit determines when a fault has occurred in one of the two channels and disables the manual channel select switch in favor of the channel selection made by the channel select circuit. In another embodiment of the invention, the output of the channel select circuit is directly used to determine whether a fault has occurred and when the manual channel select switch should be disabled in favor of the channel select circuit.

Abstract: An earth boring drill bit has staggered rows of wear resistant inserts that are positioned to provide more inserts in the rows without sacrificing insert supporting metal. The staggered rows include a first or heel row of inserts that is positioned next to the gage surface of the cutter. The second or adjacent row is located farther from the gage surface and staggered with the first row so that the first and second row inserts alternate in contacting the bottom of the borehole. Each insert has a centerline that intersects the cutter axis. The first row inserts intersect the cutter axis at a greater angle than the second row inserts. This positioning results in a more uniform section of metal between the holes of the first and second row inserts, enabling a closer spacing.
