IPC: B07C3/00
Filed: 1965-09-13
Abstract: 1,089,160. Electric selective signalling systems. SIEMENS A.G. Sept. 13, 1965 [Sept. 11, 1964], No. 38914/65. Heading G4H. In an apparatus for the conversion of data in one form to another form, in the event of the input data being ambiguous further input data is added to provide an unambiguous conversion. In a first embodiment the input data comprises four letters, two of which set electronic switch unit SI to select one of n output lines, and the other two of which set SII also to select one of n lines. Core matrix CI which interconnects the 2n lines provides an output in constant ratio code to printer Dr when the selected lines are pulsed. If, however, the input data represents an ambiguous combination, core SK, which is pulsed only by the " ambiguous " lines, initiates the input of a fifth letter to unit SIV. The ambiguous lines set unit SIII, and matrix CII which interconnects the outputs of SIII and SIV develops and unambiguous output to the printer Dr. Modifications in which core SK forms part of the matrix CI and in which unit SIII is replaced by further operation of SI are described with reference to Figs. 2 and 3 (not shown).

Abstract: 1,023,047. Gas turbine plant and combustion chambers; barker's mill type turbines. F. J. GORMAN. Oct. 3, 1963, No. 39029/63. Headings F1G, F1L and F1T. A gas turbine plant comprises a combustion space defined by a peripheral cylindrical wall and two disc end walls co-axial therewith and arranged parallel with each other in sufficient proximity to co-operate for a pumping effect when one of them is rotating, and means to introduce fuel into the combustion space, one of the end walls having a capillary structure such that scavenging and combustion air can be pumped therethrough into the combustion space due to the pumping effect but during an explosion phase back-firing of combustion gases through the capillary structure is substantially checked. An explosion gas turbine engine comprises a combustion chamber A bounded by a rotating cylindrical wall 4 and disc shaped end walls 1, 2, the wall 1 being integral with rotating wall 4 and the wall 2 stationary. Walls 1, 4 and output shaft 13 are rotated by combustion gases leaving chamber A through tangential nozzles D in wall 4. Walls 1, 2 co-operate to create a vacuum within chamber A to draw combustion air through the honeycomb structure of wall 1. The honeycomb consists of circularly wound corrugated strip forming a plurality of axial channels which allow the flow of air into the chamber A but have considerable resistance to the reverse flow of combustion gases. The axial position of wall 3, and as a result the vacuum in chamber A, is adjustable by means of a handwheel 8 and threaded block 7. Fuel, such as butane, propane, natural gas or hydrogen, is supplied through a valve 10 and pipe 9. Ignition during starting is provided by a sparking means 12. The combustion air is preheated in passing through the honeycomb wall 1 which may be made of ceramic, together with walls 2, 4.

Title: Apparatus for measuring current flow
IPC: G01R19/20
Filed: 1975-09-25
Abstract: 1481263 Measuring current APPLIED POWER AUSTRALIA Ltd 25 Sept 1975 [26 Sept 1974] 39340/75 Heading G1U In measuring current a magnetic core having more than one magnetic path one part of which contains an air-gap for preventing saturation, the gap being capable of temporary widening to permit encircling of a current-carrying conductor, and the output of an oscillator including windings wound on another part of the core is affected by flux caused by the current flow. The conductor Ls produces a unidirectional flux linking the coil pairs 18a, 18b and 19a, 19b. The part of the magnetic circuit encircling the conductor has an airgap which prevents magnetic saturation, but the windings 18-19 are wound such that the oscillator formed by transistors 31, 33 saturates the other part of the core. Transistors 32, 34 are provided such that for a zero current in L 5 , the oscillator output Fig. 3 (not shown), is symmetrical about zero and the transistor switch 35 thus provides a 1:1 mark/space ratio output. The uni-directional flux due to Ix in L 5  creates a D.C. shift in the oscillator output which changes the mark/space ratio, which can then be measured. Providing its frequency relative to the oscillator frequency is low, A.C. can also be measured.

Title: A method of manufacturing knitted fabrics
IPC: D02G1/02
Filed: 1965-09-22
Abstract: A knitted fabric, particularly a stocking, is produced from a composite filament in which different components composed of linear thermoplastic synthetic polymers with different shrinkabilities are disposed in side-by-side or in an eccentric sheath-core relationship with one another along the length of the composite filament.  The filament is given a twist such that over the length of the filament required for forming a stitch the angle of twist is at least 20 degrees.  In one example, polycaproamide and a polymer obtained by polymerizing 15 parts of hexamethylene diammonium terephthalate and 85 parts of e -caprolactam in an atmosphere of nitrogen gas at 260 DEG C were simultaneously spun together through an orifice to form a side-by-side type filament with a conjugation ratio of 1:1 by volume. Having then been drawn to a length 4.4 times its original length it was given a twist of 170 turns per metre which was fixed by heating at 70 DEG C for 10 minutes whereupon the filament was knitted and the resultant fabric treated with saturated steam at 110 DEG C for 5 minutes. Following this the fabric was dyed and placed on aluminium boards and then set at 120 DEG C for 45 seconds in saturated steam with subsequent drying and cooling.  The filaments were found to have a twist of 60-120 degrees per unit stitch length.  Different forms of nylon may be similarly spun and given a false twist treatment of about 1500 turns per metre.  After heated plate treatment to remove the residual torque the filament was knitted as before to give the required stitch formation.  Generally, for any composite filament produced the sequence involves twisting, heat fixing, knitting and subsequent heat finishing of the fabric to produce the required fabric appearance and stitch structure.
