Abstract: 720,827. Shearing. MORGAN CONSTRUCTION CO. March 19, 1953, No. 7689/53. Class 83 (4). A rotary shear for severing a longitudinally travelling rod or the like comprises two cooperating cutting discs mounted on parallel rotatable shafts and positioned at an acute angle to the line of rod travel and adapted to sever the rod as it is deflected laterally between them, a housing rotatably supporting one of the shafts and hinged to a support structure and a pitman rod lifted and lowered by an eccentric to swing the housing about its hinge to separate the discs and allow the rod to pass back between them. An upper cutting disc 10, on rotated shaft 12 provided with a flywheel 17 and mounted in a housing 16 pivoted at 26 ona base 23, co-operates with a lower cutting disc 11, on a rotated shaft 19 provided with a flywheel 21 and mounted in a housing 20 also pivoted at 26 to the base 23, to sever a length from a metal rod, fed longitudinally along a guide channel 80 inclined to the plane of the discs and given a transverse movement to pass the rod, for cutting, between the discs. In order, after cutting, to allow the rod to pass back to its original position, the discs are moved apart by swinging the housings 16, 20 about their pivot 26, the lower housing being guided by spaced fingers 32 on the base 23 and the upper housing by spaced fingers 34 on the lower housing. The swinging of the upper housing 16 is effected by pitman rods 53 mounted at their lower ends on eccentrics 52 on a shaft 51 and at their upper ends on pins 54 eccentrically carried by a shaft 55 adjustable in the housing 16 to compensate for wear of the disc. A bifurcated pitman rod 72 mounted on eccentrics 71 on the shaft 51 is adjustably connected to the lower housing 20. The eccentrics are so mounted on the shaft 51 that they are located in dead centre position when the discs are in their cutting position. The shaft 51 is oscillated by a hydraulically-operated rack 62, adjustable stops 69 limiting movement of the pitman rods.

Title: Improvements relating to ion-exchange treatment of wines, fruit juices or other alimentary liquids
Inventor: AUSTERWEIL GEZA VICTOR
IPC: A23L2/78
Filed: 1954-03-18
Abstract: Wines, fruit juices and other alimentary liquids are passed through ion exchange beds in which the contact time between the liquid and bed is automatically changed.  The change is brought about either by increasing the cross section area of the bed from the entry to the exit or by reducing the quantity of exchangeable p  H ions in the first layers of the bed.  By this latter method exchange of heavy metal cations is accelerated.  The reduction in H ions is brought about by saturation with Ca, Mg or NH4 ions.  The liquids may pass through a cation exchanger followed by an anionic exchanger.

Title: Apparatus for providing acceleration information
IPC: G01P15/08
Filed: 1972-02-21
Abstract: 1388953 Electronic fuze system WESTING- HOUSE ELECTRIC CORP 21 Feb 1972 [4 March 1971] 7889/72 Heading F3A [Also in Divisions G1 and G4] An apparatus (Fig. 2) providing an output signal at line 30 when a predetermined acceleration has been sustained by an object for a predetermined time comprises an accelerometer 12 which provides a signal to an AND gate 16 whenever the sensed acceleration exceeds the predetermined value, a clock 18 providing positive pulses on a line 19, an inverter 17, and a counter 23 which counts the clock pulses when the AND gate 16 becomes conductive and gives an output which renders an AND gate 27 conductive after the predetermined length of time. As applied to an artillery shell to arm a fuze downrange, two groups of accelerometers are provided (Fig. 3): one 40 registering setback accelerations and the other 64 registering simultaneously spins, i.e. centrifugal accelerations. The setback accelerometers 40 provide signals on lines 41 and 42 for 100 g. and 600 g. respectively of the shell. An output on lines 51 and 59 occurs when these accelerations have been sustained for periods of 5 millisecs. and 3 millisecs. respectively. These outputs, and an output on line 66 of the spin accelerometer group occurring when the spin reaches 100 g., are fed to an AND gate 80. The AND gate 80 also receives the output from the setback accelerometer circuit on line 41 through an inverter 62 so as to open only when the acceleration has fallen below 100 g., to ensure that the shell is clear of the muzzle. To ensure that the shell has travelled a certain distance downrange before the safe-arm signal on line 90 is given, a counter 85, programmed according to the type of shell, is fed with signals, representative of different muzzle velocities, from the accelerometers of the spin sensor group 64. The counter 85 counts signals from the AND gate 80 and, when the predetermined count is reached, opens AND gate 88 to produce a safe-arm signal and to close the gate 80 through an inverter 63.
