Title: Improvements in or relating to methods of making resistance thermometers
Inventor: BALES WILLIAM HENRY
IPC: C10G17/06
Filed: 1964-06-22
Abstract: A resistance thermometer is made by applying to a wire helix a liquid which coats the wire and extends between the turns through the whole length of the helix.  The coating liquid is of high surface tension and low angle of contact, and when set, forms an electrically insulating support for the wire.  The liquid may be glass, either molten or mixed as particles with water or alcohol in which case the assembly is heated to evaporate the solvent and melt the glass. The wire which may be Pt. has temperature-dependent resistance, and the helix may be formed on a mandrel, e.g. of Ni, the assembly then being heated in an oxygen-containing gas before the liquid is applied, so as to oxidize the exposed Ni surface so as to form an insulating layer. The mandrel is preferably tubular, and the wire may be a single helix extending along the mandrel, the mandrel then forming a return; or the helix may be double, both ends being at one end of the assembly.  The helix is preferably spaced from the mandrel over the majority of its length.  The liquid is preferably first applied to a part only of the helix and caused to set; adjustments, e.g. of resistance, may then be made to the as yet exposed portion of wire before it is then coated.  The resultant capsule, which may have diameter as low as 0.01 inch, need not be cylindrical; it may, for example, form part of a toroid.  It may be fitted into a hypodermic needle for measuring the temperature of a patient during an operation.ALSO:A wire resistance thermometer may be incorporated in a hypodermic needle for measuring the temperature of a patient during an operation.  The thermometer, which may have diameter as low as 0.01 inch, comprises a wire helix encapsulated in e.g. glass.

Title: Improvements in aircraft crash protection systems and in inertia operated electric switches therefor
IPC: B64C1/00
Filed: 1953-09-23
Abstract: 756,448. Inertia switches. GRAVINER MANUFACTURING CO., Ltd., MATHISEN, A., and WILKINSON SWORD CO., Ltd. Sept. 15, 1954 [Sept. 23, 1953], No. 26239/53. Class 38(5) [Also in Group XXI] An inertia operated electric switch used in an aircraft crash protection system (see Group XXI), includes a weight which is suspended from a spring and maintained thereby in a position which does not vary with the position of the switch except when the weight is subjected to a predetermined deceleration occuring in any direction lying in a given plane or passing through that plane from a given side thereof. The weight is a bob 16 having a centre of gravity which is lowered by making the lower portion 16b of denser material than the upper portion 16a, which is suspended by a rod 17 from the centre of a bowed spring strip 18. This strip is supported at its ends by two leaf springs 19 which are bolted to a metal' body 14. Sufficient downward force on the centre of the bowed spring snaps it across its dead centre position so that beads 31 carried by it close two pairs of spring contacts 22, 23. This downward force may result from a downward component of the force due to deceleration or from a horizontal component which urges the bob to rotate about a point on its circular knife edge flange which seats against a shoulder 14a of body 14. The force needed to operate the switch is set by moving vertically backstrips 21 slotted at their lower ends to take the shanks of bolts 20. The switch is reset by pulling up pillars 34 against springs 35 by means of strips 36, claws 33 carried by the pillars engaging the underside of the bowed spring. The switch is enclosed in a dustproof casing comprising a transparent plastic tube 10 sealed by washers 13 in bottom and top insulating plates 11, 12. Terminals 28 are enclosed by a cover 30. Specification 693,017 [Group XXI] is referred to.

Abstract: 442,951. Wireless receiving-apparatus. COLE, Ltd., E. K., Priory Crescent, Southendon-Sea, and WYBORN, E. J., Ray View, Undercliff Gardens, Leigh-on-Sea. Sept. 13, 1934, No. 26256. [Class 40 (v)] In a wireless-receiver a noise-suppression device which controls the level at which signals are operative is uni-controlled with a device controlling the response of the receiver to high frequencies. The noise suppression may be effected by a negatively polarized diode or as described in Specification 430,415. The Figure shows a system of noise suppression adjustable by resistance R3 in which the grid of the frequency changer V1 is connected to a point P such that with no signal the grid is positive but is rendered negative by the signal. The response to the higher audio frequencies is controlled by varying the sideband attenuation by the series resistance R1 in the secondary of tuned transformer T. The resistances R1, R3 are conjointly controlled. In a modification, the control of the response to higher audio frequencies is effected by a resistance in series with a high note loudspeaker which is provided in parallel to the normal loud speaker, Fig. 2, (not shown).

IPC: D06B3/32
Abstract: 267,151. Telefunken Ges. f³r Drahtlose Telegraphie. March 5, 1926, [Convention date]. Automatic exchange systems. - Wireless or wired wireless stations HI - H4 working on a common wavelength and calling each other selectively, e.g. by means of impulses, produced by a number dial, and operating step by step mechanism in the receiving stations, are interconnected with the subscribers N1 - - N3 of an automatic exchange An with the aid of transfer apparatus R comprising a high-frequency receiver HE and transmitter HS, filters Sn, Sr for keeping the speech currents and selecting impulses to their proper channels, and a group of relays. Relay J repeats impulses dialled in the high-frequency system to a selector S which, in response to a particular digit characteristic of the transfer apparatus closes its contact s to energize relays E, B, which respectively complete the loop to the automatic office and switch on the transmitter. Subsequent digits are repeated at j<2> to the automatic office, the selector, by means of circuits not shown, being made unresponsive to these impulses but being released when J falls back permanently owing to the high-frequency subscriber's switching off. When the line L is seized from automatic office, relay N energizes relay B to switch on the transmitter, and repeats subsequent impulses to the transmitter which sends them out as interruptions or modulations of the carrier wave. Relay N may be made to hold its armature n2 during impulsing or relay B may be made sluggish. Relay F. which is energized whenever a conversation is in progress between two high-frequency subscribers, prevents the operation of relay B and therefore the switching on of the transmitter if the transfer apparatus is called from either side, and connects a busy generator G2 to the line L. If a busy condition is encountered in the automatic exchange by a call originated in the high-frequency system, the usual busy tone modulates the carrier wave in the same way as speech. As shown, the calling party has control of release, but the circuits may be modified to give the control solely to the highfrequency party. Where the selective calling of the high-frequency subscribers is effected by means other than numerical impulses, the transfer apparatus includes apparatus individual to each subscriber on both systems, such apparatus being selected according to the selective method peculiar to the calling side and transmitting the number in the method peculiar to the called side. The Specification as open to inspection under Sect. 91 (3) (a) comprises also detailed description which does not appear in the Specification as accepted concerning release of the transfer apparatus under sole control of the high-frequency or of the low-frequency party or by the first to hang up.
