Title: Improvements in or relating to radio communication systems
Inventor: BURR DONALD WILLIAM
IPC: H04W88/02
Filed: 1949-01-24
Abstract: 682,844. Electric selective signalling. POSTMASTER GENERAL. May 9, 1950 [Jan. 24, 1949], No. 1944/49. Class 40 (i). A radio - communication system comprises a central station and a number of satellite stations each of which has its own calling signal consisting of a predetermined sequence of frequencies, full communication between the central station and the satellite being established when the central station radiates the appropriate call, each satellite comprising a circuit which responds to the first frequency of its calling signal to change the circuit to respond to the second frequency of its calling signal. The Specification proposes ten audio-frequencies corresponding to the digits 1, 2...0, the audio-frequencies being selected so that no one is closely adjacent the second or third harmonic of another. By transmitting several sequences of frequencies simultaneously, groups of the satellite stations can be called. Each signal of the sequence preferably has a duration of 500 milli-seconds with a spacing between signals of 250 milli-seconds. The audiofrequencies constituting the calling signal are transmitted as modulations on a carrier. Call signals consisting of a sequence of the same frequency are avoided. Operation at satellite station. The receiver comprises a squelch relay (not shown) with contacts S', S<SP>2</SP> and a transmit relay (not shown) with contacts H<SP>1</SP>, H<SP>2</SP>. The received carrier operates the squelch relay to light lamp L over contact S' and isolate the transmit relay at contact S<SP>2</SP>. The demodulated calling signal is applied over terminal 3 to a tuned circuit L', CA, in the grid circuit of valve V<SP>1</SP>; if the circuit L', CA is tuned to the first signal of the sequence, valve V<SP>1</SP> conducts, but owing to the condenser C<SP>2</SP> and resistance R<SP>4</SP>, the anode current does not immediately rise to a value sufficient to operate A, thus avoiding operation by transients. When relay A operates, slow release relay B is actuated, so that when relay A releases, relay K operates to replace condenser CA by condenser CB and retune L' to the next signal of the sequence. Relay B releases before the second signal, but relay K remains -operated for the period between signals. If now, the second signal is of the frequency to which the circuit L', CB is tuned, relay A is operated to actuate relay B and maintain relay K operated when relay A releases, relay D will operate to replace condenser CB by condenser CC, relay K remaining operated as before. 'If now, the circuit L<SP>1</SP>, CC, is tuned to the third signal; relay A operates to actuate relay B to hold relays K, D and when the signal ceases, relay A releases to actuate relay E which connects the input at 3 to the loud-speaker, disconnects the lamps L, operates a buzzer at contact E<SP>4</SP>, and connects the satellite transmitter for operation at contact E<SP>3</SP>. Relay K eventually releases to release relay D, but relay E locks over contact E'.

Title: Improvements in vehicle and aircraft control columns
IPC: B64C13/04
Filed: 1941-02-12
Abstract: 546,210. Aircraft controls. GENERAL AIRCRAFT, Ltd., and WELS, O. Feb. 12, 1941, No. 1946. [Class 4] An aircraft control column which is rotated to actuate the ailerons and moved longitudinally to actuate the elevator has a hand-grip mounted concentrically with the column but upon a cranked extension thereof so as to clear an instrument board or other obstruction. The hand-grip may be adjusted axially of the column. In one form two hand grips 9 forming part of a wheel concentric with a horizontal column 7 are mounted upon a cranked extension 8 of the column. The column 7 rotates in a sleeve 10 mounted upon two normally vertical links 13, 14 and carries a lever 19 for actuating the aileron controls. A lever 20 on the link 13 actuates the elevator controls. The two links are of unequal length so that the grip does not change its vertical position as the column is moved axially. In another form the column 7 is suspended from a pair of links. In still another form the extension 8 is suspended by links from the main column the links forming the only connection between them. In this case only the extension 8 moves axially. Fig. 3 shows a modification in which the extension 8 is carried by a bracket 26 from a squared shaft 7 sliding in sleeves 22, 23, the former having a lever 24 for actuating the ailerons. In all cases the grips 9 are mounted on a sleeve splined to the extension 8 the sleeve being movable axially over the extension 8 by a screw turned by a knob 30.
Patent GB-450842-A (GB)
Title: Manufacture of 2-methyl-3-hydroxy-quinoline-4-carboxylic acids
Filed: 1935-01-21
Abstract: 2-Methyl-3-oxyquinoline-4-carboxylic acids are prepared by reacting a halogenacetone with a salt of an isatic acid in presence of an alkaline earth hydroxide and with the aid of heat. Calcium, magnesium and strontium hydroxides are used in this process which is preferably carried out between room temperature and 100 DEG  C.  It is also possible to start from an isatin using a correspondingly larger amount of alkaline earth hydroxide to convert this substance to a salt of an isatic acid.  In examples: (1) isatin is heated with chloracetone and milk of lime at 80--90 DEG  C. to give 2-methyl-3-oxyquinoline-4-carboxylic acid; (2) 5-phenylisatin is heated with milk of lime and then chloracetone added and heating continued at 80--90 DEG  C.; 6 - phenyl - 3 - oxy - 2 - methyl - 4-quinoline carboxylic acid is obtained; (3) 5.7-dichlorisatin is similarly treated as in (1) and (2) to give 2-methyl-3-oxy-6.8-dichlorquinoline-4-carboxylic acid; (4) isatin is first treated with caustic soda, slaked lime then added and the mixture reacted with chloracetone at 60--80 DEG  C.  On heating above the wetting point the products lose carbon dioxide to give the corresponding hydroxyquinaldines On coupling with diazo-compounds they yield azo-dyes also with elimination of carbon dioxide; reduction of these azo-dyes yields the 2-methyl-3-oxy-4-aminoquinolines.  The prior art is referred to.

The needle-bar 3 and loop-taker shaft 4 are carried by a bail 6 adapted to be reciprocated longitudinally of the machine. In the embodiment shown means are provided for adjusting the amplitude. and midpoint of the vibration. The reciprocation of the bail 6 is produced by a link 11 which is pivoted to the bail and carries a roller engaging a track in an angularly-adjustable guide member 15, the link being oscillated by a crank 8 and having an endwise movement imparted to it by reason of the inclination of the guide 15. The middle part of the guide track is made arcuate, with a radius equal to the length of the link 11, so that when the guide is in its neutral position, for a straight seam, the bail is absolutely stationary ; the end portions of the track are of different curvature, to minimise the lateral movement of the needle while it is in the work during zig-zag stitching, and they may be somewhat enlarged. The guide 15 is carried by a spindle with an adjusting knob, and this spindle is mounted in an eccentric bushing in the machine frame, angular adjustment of the bushing thus providing lateral adjustment of the neutral position of the bail 6.
