Title: Electromechanical resonators and electric circuit devices utilizing the same
IPC: H03H3/04
Filed: 1965-04-13
Abstract: 1,105,114. Piezoelectric elements. KOKUSAI DENKI KASHUSHIKI KAISHA. 13 April, 1965 [13 April, 1964; 24 Aug., 1964; Dec. 28, 1964], No. 15766/65. Heading H1E. [Also in Division H3] The resonant frequency of a composite electromechanical resonator is controlled by means of an impedance element not forming part of either the input or the output circuit. The resonator consists of a metallic member in the form of a tuning fork or a lamina 2 having either two or three separate electroded piezoelectric elements attached to one or both faces. The metallic member forms a common electrode. In one embodiment, input and output terminals 3, 4, Fig. 1a, are connected across two of the elements and the electrode 5 of the third element is connected to earth through a variable impedance, e.g. a capacitor (not shown), which enables the resonant frequency to be varied. In another embodiment, the resonator is used in a two-terminal arrangement, the terminals 3, 4a being connected across one of the elements and the variable impedance across terminals 5, 4a. The resonators may be used to replace the usual tuned circuits in a ratio frequency discriminator.

Title: Weighing apparatus
Inventor: PAGET ARTHUR AVERIL
IPC: G01G23/18
Filed: 1958-05-19
Abstract: 857,228. Weighing apparatus. VANDOME & HART Ltd. May 19, 1959 [May 19, 1958], No. 16010/58. Class 143 A ticket-issuing weighing machine comprises a transparent weight-indicating scale disc 1 and an arrangement employing an electronic flash discharge tube 3 as a light source for making a contact print of the weight indicated on the scale disc 1. As shown two flash discharge tubes 3 are mounted on one side of the disc and a housing 4 is tiltably mounted on a shaft 14 on the other side of the disc. The housing 4 supports a roll 5 of light sensitive dyeline paper which is guided over a stainless steel plate 6 past a printing position opposite the tubes 3, the paper then passing between rollers 7, the lower of which dips into a bath 12 of developing fluid, on to a table 8 below a knife 9. A transparent arrow-engraved strip 19 stands proud of the plate 6 to define a slot therewith through which the dyeline paper is guided. The upper roller 7 is freely journalled on a shaft 10 to which are keyed a cam 13 and a spur wheel 11. The spur wheel 11 has some teeth missing but normally meshes with a spur 15 keyed to the shaft 14 on which the lower roller 7 is also keyed. In operation, when the shaft 10 is turned, the cam 13 engages a bar 16 on the housing 4 to rock the housing and thereby press the dyeline paper against the disc 1, the disc being supported by a backing plate 17. Deflection of the bar 16 operates a micro-switch lever 18 to fire the tubes 13 and continued rotation of shaft 10 then brings the spur wheel 11 into mash with wheel 14 to effect rotation of the lower roller 7. The paper is thereby coated with developer and fed onto the table 8, where it may be torn off against the knife 9. Instead of dyeline or ferroprussiate paper, discrete sensitised tickets may be used, and instead of a moving scale a moving pointer may be photographed against a fixed scale. The paper may be held sufficiently closely to the scale to obviate the necessity for movement thereof between positions contacting, and clear of, the scale, and sensing means may be used to ensure the photographing of the scale in the mean position of its oscillations. The machine may issue undeveloped tickets, the developer being added subsequently. Suitable developers include aqueous hexamine and dilute solutions of various naphthalene sulphonic acid derivatives. Specification 857,229 is referred to.

Title: Improvements in or relating to the production of expanded plastic materials
IPC: C08J9/04
Filed: 1943-10-07
Abstract: Producing expanded ethenoid type polymers or copolymers by forming gas bubbles in a dough consisting of the partly polymerized material obtained by heating a liquid monomer or low polymer at a moderate temperature until a rubbery consistency is produced and heating the material further until it is strong enough to retain the cellular structure.  Ethenoid compounds specified are polystyrene, polymethyl methacrylate, polyethylene and styrene-methyl methacrylate copolymer. The gas bubbles may be produced either by gassing or by the addition of a blowing agent such as sodium carbonate, ammonium carbonate or diazoaminobenzene. The blowing agent may be added to the monomer before the production of the partly polymerized material, or may be added to the partly polymerized material.  Inhibitors such as hydroquinone and accelerators such as benzoyl peroxide may be used. Fillers, plasticizers and colouring materials may be incorporated either in the monomer or in the partly polymerized material.  In an example, monomeric styrene is heated until it assumes a rubbery condition, sheeted out, and subjected to gas pressure at 100 DEG  to 110 DEG  C. This material is then put in a mould and further heated.

Abstract: 1491103 Measuring force TOYOTA JIDOSHA KOGYO KK 22 April 1975 [11 Oct 1974] 16632/75 Heading G1G An axial force within a body (e.g. a bolt) is measured by applying longitudinal and transverse mode ultrasonic waves to cause forced oscillation of the body, measuring natural oscillation frequencies of the body in both the longitudinal and transverse-wave modes, and comparing a calculated function of these frequencies with calibration data relating said function and axial force, the frequency band of the applied ultrasonic waves being selected such that the fractional change of natural frequency with stress in the body is different for the two wave modes. Experimental results are given for bolts under axial forces up to five tons with applied frequencies in the 5 MHz region. It is shown that, where A and B are the natural frequencies for longitudinal and transverse waves respectively, the value A-B or (A-B)/A can be used as a measure of force and is substantially the same for all samples of any given type of bolt.
