Title: Improvements in carrier wave communication
IPC: H04B14/08
Filed: 1942-03-12
Abstract: 652,221. Radio signalling ; frequency modulation. MURPHY RADIO, Ltd., DAVIES, K. S., and HAWKINS, G. F. March 12, 1942, No. 3289. Drawings to Specification. [Class 40 (v)] The ratio of signal to noise in a radio receiver is increased by transmitting the signal as a frequency or phase modulation of a constantamplitude sub-carrier wave which is itself amplitude-modulated on a shorter carrier wave. At the receiver, the carrier is amplitudedemodulated and the resulting sub-carrier is freed from impulsive interference, e.g. by the means described in Specification 532,521, and the signal is then recovered from the subcarrier by frequency demodulation. A superheterodyne stage may precede the amplitudedemodulation, and at this or other highfrequency stages the circuits have a band width several times that needed for the highest signal frequency. A limiting amplifier may follow the suppressor of impulsive interference.

Title: A method of measuring the hardness of a metallic workpiece
IPC: G01N23/203
Filed: 1965-01-26
Abstract: 1,099,781. Photo-electric hardness gauges. INDUSTRIAL NUCLEONICS CORPORATION. Jan. 26, 1965 [March 23, 1964], No. 3407/65. Addition to 1, 038, 998. Heading G1A. In the measurement of the hardness of a material, using the #-backscatter gauge of the parent Specification, the sensitivity of the apparatus is maximized by adjustment of the energy response of the detector before the actual measurement is carried out. This is done using either a filter of suitable thickness in front of the detector Fig. 1 (not shown) or a pulse height discriminator modifying the detector output Fig. 2 (not shown). The thickness of filter or discrimination level of the discriminator is chosen by experiment. First and second measurements on two samples of the same homogeneous material but of different known hardnesses are taken and repeated, varying the detector resonance each time, until a maximum difference is obtained between the two measurements. One cause of the increased sensitivity is that background scattered radiation is removed. The use of the discriminator allows a particular band width of pulses to be counted thereby increasing sensitivity. The sources may be Sr90, Kr85 and the detector an ionisation, Geiger-Muller or scintillation counter, crystals for the latter being of anthracene, stilbene or plastics phosphor.

Title: Apparatus for Jointing Timber Sections.
IPC: B27M3/00
Filed: 1967-01-24
Abstract: 1,155,352. Woodworking. M. FEIGLIN & SONS PTY. Ltd. 24 Jan., 1967 [9 Feb., 1966], No. 3422/67. Heading B5L. Apparatus for continuously joining lengths of timber to form a unitary composite structure comprises means for conveying two or more trains of timber lengths 5, 6 laid in end to end alignment to a glueing station 10 where glue is applied to at least one face of the lengths in one of the trains, drive means 10a, 12 for carrying the trains into convergence in a guideway after application of the glue to effect substantial aligned interfacial contact of the two trains, means 26, 27 for passing the glued and aligned trains through a compression zone when lateral clamping pressure is applied to the trains, and a field of radio frequency associated with the compression zone to effect curing of the glue during passage therethrough. The timber lengths have their ends formed with finger joints to which glue is applied at a station by an applicator as the lengths are clamped by pneumatic clamps and fed to a conveyer 4 where they are arranged end to end in two trains 5, 6. The trains pass between pairs of smooth rollers 7, 8 which fed the trains past the applicator 10 for applying glue to one of the side faces of one of the trains and between upper scored rollers 13, 14 and lower smooth rollers, the scored rollers being driven at a lower speed than the smooth rollers to ensure that the lengths of timber are pressed together end to end. From the rollers, the trains pass between converging guides 10a, 12 on a guide table against which the trains are then compressed against each other by the chains 27, 28. The chains are driven at a slower speed than the rollers so that the timber lengths are again pressed end-to-end while being compressed, one of the chains having a number of links carrying spring-pressed pressure plates. While the lengths of timber are between the chains, the glue is cured by radio frequency energy from upper and lower electrodes. The assembly of lengths may be cut to a desired length by a saw 42 which travels with the timber and is operated when a switch 43 is activated by the leading end of the assembly, the switch also activating a pneumatic clamp 44 which clamps the saw to the timber. An arm 52 removes the cut length.
