Title: Improvements in or relating to explosive initiators
Inventor: PEYTON STANLEY VICTOR
IPC: F42B1/04
Filed: 1957-09-03
Abstract: 894,576. Ammunition fuzes. AVIATION, MINISTER OF. Aug. 28, 1958 [Sept. 3, 1957], No. 27835/57. Drawings to Specification. Class 9(1). In a high explosive initiator a violent igniferous composition is used in conjunction with a secondary explosive. The igniferous composition may be a capsule of lead styphnate or lead dinitro-resorcinate and the secondary explosive a pellet of cyclonite or tetryl the two being connected by a "stem" of the secondary explosive packed in a narrow channel. To produce the detonation the igniferous capsule and secondary explosive must be separated by an air-gap. A safety shutter may be movably mounted in the airgap.

Title: Magnetic core half adder
IPC: H03K17/82
Filed: 1957-09-04
Abstract: 854,447. Half adders. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 4, 1957 [Sept. 6, 1956], No. 27975/57. Class 106 (1). [Also in Group XXXV] Four half-adders are described each using one or more toroidal magnetic cores with one or more holes therein. In each embodiment the core (or cores) is first reset by a reset winding, then the digits to be summed are applied in the form of pulses to two input terminals and as a result " carry " and " sum " outputs are immediately produced, and the arrangement is such that when the core (or cores) is next reset, prior to the next addition, it again produces the " sum " and " carry " outputs of the previous addition, these outputs, however, being in the form of pulses of the opposite polarity to those produced at the time of the addition. In the first embodiment, Fig. 1, input pulses are applied to windings 20 and 22 by two devices 30 and 32, carry " and " sum " outputs are produced at terminals 45 and 44, respectively, and a device 36 applies reset pulses to a winding 34. Single cores are also used in two other embodiments (Figs. 2 and 5, not shown) and in the remaining embodiment (Fig. 3, not shown), two cores are used, this embodiment differing from the others mainly in that the input pulses can be of either polarity. Specification 845,431 is referred to.

Abstract: 754,408. Trimming helicopter rotor blades. DOMAN HELICOPTERS Inc. Sept. 29, 1954 [Nov. 16, 1953], No. 28111/54. Class 4. [Also in Group XIX] A device for measuring the aerodynamic pitching moment of a part of a fullsized aerofoil B as an aid to trimming helicopter rotor blades or the like, comprises a frame 10, 11, 12, 13, 14 carrying at least two spaced means 17, 19, 20, 24 for supporting the aerofoil, having freedom of movement laterally and being angularly adjustable about the mean or approximate aerodynamic centre of the aerofoil, means to adjust angularly at least one of the supporting means, means to measure the turning moment of the aerofoil, a jet mechanism having a nozzle which is short compared with the aerofoil in the direction of its span and is directed towards the leading edge of the aerofoil, and means for moving the jet and supporting means relative to one another to present the jet nozzle at various points of the aerofoil. In Figs. 1 and 2, the aerofoil B is received in a notch 18 in each of two horizontal members 17 suspended on knife edges 21 in line with the aerodynamic centre C, from two rods 19, 20, themselves suspended on knife edges 23 from a horizontal member 24. This member is pivoted on a knife edge 27, in line with edges 23, on a bar 28 secured to a structural member 12 of the frame. A further bar 35 secured to member 12 supports a lever 33, 37, the neutral position of which is determined by a screw 39 and spring 38. The end of lever 33 is connected by rod 32 to the member 24, and is attached to a strain gauge 34. The jet nozzle and assembly is movable on rails so as to present the jet to any narrow portion of the blade. In operation, the blade is angularly adjusted by screw 39 until no lateral force is exerted on the blade by the jet, as indicated by the setting of a pointer 52 on a scale 53, or by a pointer 54 on a scale 55 secured to the jet nozzle. The strain gauge is read to indicate the pitching moment, and a trim tab T is adjusted to give a required value of pitching moment all the way along the blade. In Fig. 4 (not shown), the blade is set in a notch in a semi-cyelindrical member rotatable in the member 17 to adjust the blade in place of screw 39. Fig. 3 (not shown) shows a jig for holding the blade straight.

[Also in Divisions G3 and H2] An inverter producing a sinusoidal output has a capacitor 1 charged in one direction through an inductor 3 when SCR's 2 and 8 are closed, and in the other direction when SCR's 5, 7 are closed. The SCR's are triggered by pulses generated when the charging current passing through zero. The output voltage is stabilized by comparing it with a reference voltage 21 to derive an error signal to adjust the firing of the switches and also by deriving a second error signal dependent on the output current by means of a current transformer 17. The frequency is stabilized by an inductor 13 which is switched into circuit for different times during the cycle. In a modification, Fig. 8 (not shown), the output voltage is stabilized by rectifying part of the output and feeding it back to the battery. In place of the SCR bridge, two SCR's may be employed to charge and discharge the capacitor Fig. 1 (not shown), or to charge it from two opposite polarity sources, Fig. 2 (not shown).

Abstract: 1399895 Floor coverings ARMSTRONG CORK CO 16 June 1972 [16 June 1971] 28422/72 Heading B6G In a method of laying a resilient decorative floor covering comprising a fused vinyl resincontaining wear layer and a strippable backing layer which is substantially more thermally dimensionally stable than the wear layer and which is bonded to the wear layer to maintain the wear layer in a state of tension, the strippable backing layer is removed at the laying site and before the stresses in the wear layer have relaxed the wear layer is secured at its periphery to the surface to be covered to prevent relative movement between the wear layer and in the surface. In Example 1 a vinyl resin-containing plastisol containing a blowing agent and addition polymerizable monomer is coated on to a beater saturated asbestos felt backing having a methyl cellulose release coating, the coating gelled in an oven, printed with an ink containing an addition polymerization catalyst, coated with a clear coating material and then heated in an oven to expand the vinyl resin-containing composition into a foamed layer having overprinted area which are not expanded. After removal of the backing at the laying site the vinyl wear layer is secured at the perimeter of the surface to be covered by mechanical fastening means. In Example 2 a filled tessellated vinyl composition decorative surface covering in which the wear layer is bonded to a beater-saturated asbestos felt backing having a methyl cellulose release coat, is used and at the laying site the wear layer, after stripping of the backing, is laid over a foamed backing and secured to the surface to be covered at the periphery by means of an adhesive.

This is caused by the coefficient of expansion of the cups being less than that of the body 1. Alternatively, the cups may be outwardly bowed if their expansion coefficient is chosen larger than that of the body 1.
