Title: Improvements relating to gyro-compasses
Inventor: SASAKI JUNICHI
IPC: G01C19/38
Filed: 1960-07-11
Abstract: 957,196. Gyroscopic apparatus. KABUSHIKI KAISHA HOKUSHIN DENKI SEISAKUSHO: July 11, 1960, No. 24179/60. Drawings to Specification. Heading G1C. The settling time of a gyrocompass is reduced by starting the rotor at reduced speed and in - creasing in one or more steps up to its normal operating speed. If the rotor is driven by an electric induction motor the power may be supplied initially from a source of power of lower frequency than normal and subsequently switched to a source of normal frequency. To ensure that the transient oscillation produced by the change of speed is in antiphase to that produced by the previous change of speed the switching may be under the control of a pre-set timing relay, a selsyn system coupled to the gyrocompass or a tachogenerator whose output voltage is a function of the rate of oscillation of the sensitive element.

Title: Uranium-aluminium alloy containing one or more further elements
IPC: C22C21/00
Filed: 1958-07-28
Abstract: An alloy for nuclear reactor fuel elements consists of 80-99,5 atomic per cent. of Al and U (in the atomic proportion range 90 : 10-96,5 : 3,5) and the balance one or more of Si, T, Ge, Zr, Sn, Pb, In. Tl, Fe, Nb or Ga.  The composition ensures that at least 20% by weight of the total U and Al are present as U Al3 so that the alloy can be hot-rolled without protective cladding.  In an example 2450 gm Al was melted and 150 gm Si and 2400 gm U added in that order.  After stirring, the melt was degassed by cooling to 600 DEG C. and returning to 1175 DEG C. five times; it was then cast into a graphite mould.  The cropped ingot was then multipass hot-rolled and punched into cores each of which was completely enclosed in an Al frame. Each assembly was hot-rolled, flux annealed, washed and etched, cold rolled, stress relieved and blister annealed.

Title: Hypoid gear cutting
IPC: B23F9/10
Filed: 1952-09-26
Abstract: 727,166. Gearing-cutting. FIAT SOC. PER AZIONI, and INGRANAGGI MAMMANO SOC. PER AZIONI. Sept. 26, 1952 [Sept. 29, 1951], No. 24235/52. Class 83 (3). Relates to a method of manufacturing curved toothed hypoid gears with offset orthogonal axes by the continuous generating process employing a face-mill cutter Q which simultaneously cuts both flanks of each tooth space, the axis of the tool being kept parallel with the general axis g-g of the machine and being rotated about the latter at a constant radial distance. The wheel is cut as an ordinary curved tooth bevel gear with its axis inclined at an angle α<SP>1</SP> to the basic plane of the machine and its apex V<SP>1</SP> on the general axis, and the pinion is cut by displacing the apex V<SP>2</SP> of its pitch cone on the same plane with its axis inclined at an angle α<SP>2</SP> to the said plane, the angles α<SP>1</SP> and α<SP>2</SP> being given by the formulµ:- and the angles # and # being defined in terms of k, the ratio of the angular speeds, Z 1  and Z 2 ; the numbers of teeth; and the angle between the contact generatrices V 1 P, V 2 P and the difference in spiral angles of the teeth. The tool has three sets of cutters each set including some roughing and two finishing cutters, so that the blank rotates through three tooth spaces while the tool rotates through one revolution. In Fig. 3, U represents the tool axis normal to the plane of the Figure and UP the cutter radius. If the flat wheel, centred at V1 and represented by the plane of the drawing, and the tool are counter-rotated, the tooth curve SPS is an elongated epicycloid arc, otherwise it is an elongated hypocycloid arc. The method of calculating the smallest practical pitch radius of the wheel is given in the Specification. A single motor 1 rotates the tool Q through gearing 4, 5, the tool drum through gearing G, 7, 8, L, S, and the vertically-adjustable workpiece I through gearing G, 7, 11, 12, 14 and a splined shaft W. For any particular calculation, a slight modification generally needs to be made in view of the fact that the requisite ratio q of the gears G cannot be exactly obtained. The nearest ratio is therefore used and the calculations re-made on that basis. The settings for the tools for cutting both the pinion and the gear are the same. The ratio k is preferably as near unity as possible in order to minimize slip.

Abstract: 721,065. Moulds. GRIFFIN WHEEL CO. Sept. 29, 1952, No. 24321/62. Class 83 (1). A mould cavity is defined by a number of graphite blocks through at least one of which passes a riser having a gas-permeable liner. A mould for casting a steel wheel is composed of two graphite blocks, the upper block 12 being clamped between annular rings 4, 6 and the lower block 20 between a ring 16 and a tray 22. The blocks are machined to define a mould cavity comprising a rim section 28, a plate section 30 and a hub section 32. A graphite sleeve 34 forming a gate extends through the block 12 from the cavity 32 and one or more risers extend upwardly through the block from the plate section, each such riser having a gas-permeable liner of, for example, core sand and a binder. The liner 42 may be formed by inserting a plug 44 of, for example, aluminium in the riser opening to define an annular cavity, and filling the cavity with the moulding mixture which becomes baked by heat from the block and from an electric heater 52 contoured to shape the bottom of the liner. A hole 56 is subsequently formed in the bottom of the cup 42. Specification 721,059 is referred to.

[Class 40 (iii).] In a filter section constructed as shown, the arms can be varied in one degree of freedom without affecting the image impedance and transfer constant ; or if the arms are varied in two degrees of freedom the transfer constant can be altered while the image impedance is unaffected. The dimensions are as follows : A = 2KZ1; B = K<-1> (1 - y) Z2; C = K <1>yZ2; D = 2K-<1>y{(K<2> + y - 1)/ (1 - K2) Z2, where K, y are fractions and Z1, Z2 impedances. The image impedance is Z2#{Z1/(Z1 + Z2)} and is therefore independent of y and K. The transfer constant is tank<-1>[K#|Z1/(Z1 + Z2))]. Hence if y is varied these quantities are unaffected; while if K is varied, only the transfer constant is affected.
