Title: Improvements in magnetic core shift registers
IPC: G11C19/04
Filed: 1956-08-13
Abstract: 841,619. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 13, 1956 [Aug. 16, 1955], No. 24662/56. Class 40 (9). [Also in Group XIX] Each storage core S of a shift register is coupled by a loop 10, 12, 13, to two auxiliary cores T which provide transformer coupling with the preceding and following stages. In the register of Fig. 1 pulse generators A, B, C, and D produce pulses in the sequence shown in Fig. 2. It is assumed that all cores except S1 are in a zero remanence state, S1 being in a one state, and that current entering a core winding at its dotted end tends to shift the core to a zero state. From time t1 current IA shifts core S1 from one to zero and current induced in winding 10 shifts core T2 to a one state. Current induced in winding 13 of core T2 tends to switch cores S2 and T3 to one states but the coercive force of T3 is not overcome and only S2 switches to a one state. After time t2 current IC flows to reset core T2 to zero and currents are induced in the windings 12 and 13 which do not affect the state of cores T1 and T3 but tend to switch cores S1 and S2 from their respective zero and one states. As the current IA continues throughout the duration of the IC current, core S1 is not switched and as the rate at which T2 is restored is kept low the coercive force of core S2 is not overcome so that S2 is not switched either. By time t3, therefore, the one state of S1 has been transferred to S2. The subsequent current pulses IB and ID transfer the one state of S2 to S3 and core T3 is set back to zero by time t6. Cores S must be of rectangular hysteresis material but cores T need not be so but if they are the reset windings 14 connected to sources C and D may be connected in a single series circuit. In place of being pulsed the cores T may be reset by a continuous D.C. bias. To increase the coercive force presented by the cores S so as to increase the rate at which the T cores may be reset, a bias may be applied to the S cores. If the IA and IB pulses are applied as shown in Fig. 6 only one winding is needed on each S core. Specifications 777,519 and 828,708 are referred to.

Title: An improved heat resisting material and method for producing it
Inventor: PARR NORMAN LAWRENCE
IPC: C04B35/591
Filed: 1961-07-07
Abstract: A method of making an improved heat-resisting material comprises compacting a powdered alloy compounded of silicon and one or more other metallic elements, present to the extent of at least 5% by weight of the silicon, which are unreactive to nitrogen at the subsequent firing temperature and firing the compact in nitrogen at a temperature and for a time sufficient to complete the nitriding reaction between the silicon and the nitrogen.  The compacted powder may be fined in nitrogen initially at a temperature below the melting point of the alloy for a time long enough to produce sufficient silicon nitride to bond the particles together, the reaction then being completed by continuing the firing at a temperature above the melting-point of the alloy.  The alloys specified are Si-Ni, Si-Co, Si-Ni-Co.  In a typical example, a 80% Si/20% Ni alloy powder is fired in nitrogen initially at 950 DEG  C. for 50 hours, and then at 1450 DEG  C. for 10 hours.  Specification 942,082 is referred to.ALSO:A method of making an improved heat resisting material comprises compacting a powdered alloy compounded of silicon and one or more other metallic elements present to the extent of at least 5% by weight of the silicon which are unreactive to nitrogen at the subsequent firing temperature and firing the compact in nitrogen at a temperature and for a time sufficient to complete the nitriding reaction between the silicon and the nitrogen.

Class 110(ii) [Also in Group XXVIII] Outwardly-sliding vanes 6 have their tips sharpedged, or beaded, Fig. 7 (not shown), to give linecontact with the working chamber, the bore of which is formed of two pairs of circular arcs, of different radii, joined by curves designed to give uniform flow of fluid through the chamber. The undersides of the vanes may also act as working chambers. The displacement of the working chamber (Fig. 8) may be varied by axial movement of the side cheeks 7A, 10 some plates of the vanes 6, which are laminated in this case, being severed " to decrease the effective width of a vane. In Fig. 2 each vane has a channel 6A on its leading face to connect the space under a vane with the outer, crescent-shaped, working chamber..End cheeks 7, 8 are preferably of anti-friction material. An inlet 2A leads to an annular chamber 2B which communicates with the working chamber by way of axial ports 7A in the cheek 7. Outlet ports 8A, in cheek 8, lead to passages 3B and a delivery port 3A. In a modification, Fig. 5 (not shown), the rotor 4 has an enclosed chamber 4A within it connected by radial holes to the bottoms of the vane slots. In these slots are plungers which force out the vanes under pressure of a liquid in the chamber 4A A further modification, Fig. 6 (not shown), has a rotor with a diameter substantially smaller than the minimum diameter of the working chamber, and each vane has a rounded bead on its outer edge which is pressed outwards by pressure fluid in the chamber. Figs. 8, 9 show an axiallymovable working-chamber comprising a member 18, secured to the rotor 4, and a side cheek 7A clamped to 18 by a nut 19. A keeper ring, or side cheek 10, is mounted on a step 18A of the member 18, and is free rotationally. Axial movement is secured by a handwheel 13. Outlet holes 2E lead to a delivery port 15A. The ring 10 has two axial grooves on its outer periphery which communicate with the inlet chamber 3C. In a further modification, Figs. 12, 13 (not shown), the vanes act as reciprocating pistons only, the crescentshaped outer chambers being inoperative.

[Also in Group XXXV] Apparatus for measuring the moisture content of granular materials comprises a capacity cell 20 (Fig. 3) containing the material as a dielectric, in the tuning circuit of an oscillator 11 whose output is mixed with a fixed frequency in valve 33, a calibrated condenser 21 in series with the test cell being adjustedto give a constant beat frequency as indicated on a tuning indicator 44. For initial checking, a small fixed condenser 23 may be added across the cell 20 by a switch 24, the corresponding charge on condenser 21 to retune the circuit being adjusted to a constant value by a preset condenser 26 for each different dielectric of the cell 20. To avoid the resetting of condenser 21 for different conditions, a series of switchcontrolled condensers may be made available. The indicator section 15 (Fig. 3), may be modified to include a frequency discriminator of known kind, in which a double diode valve 66 (Fig. 5) is fed through a tuned transformer 63, and the voltages across the individual cathode loads 67, 68 are applied to the control grids of two balanced valves 69, 70, a milliammeter in the anode circuits indicating the degree and direction of unbalance current due to the divergence of the beat frequency from the standard value. The indicator may be made to perform a controlling function by passing the anode currents of valves 69, 70 through the windings of two D.C. motors driving differential bevel gear with an output shaft whose speed and direction is thus indicative of the frequency departure, and can be used to control the speed or duration of an automatic drying system. Specification 687,477 is referred to.
