Title: Improvements in or relating to navigation aiding radio systems
IPC: G01S1/02
Filed: 1937-08-07
Abstract: 500,359. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and COCKERELL, C.S. Aug. 7, 1937, No. 21798. [Clase 40 (v)] Course - indicating signals of the overlapping-beam type are shown as circular traces on a cathode-ray tube. The anode circuit 2 of the last amplifier is tuned to the common modulation frequency, and is shunted by a phase-splitting branch 6, 7 which applies the received signal voltages in phase-quadrature to the plates 8, 9 of the cathode ray tube. Each dash DA and dot DO therefore appears as a circular trace, the longer duration of a dash making it appear the brighter. The diameter of each trace is a measure of its received strength so that Figs. 2 and 3 represent " off course" indications to port and starboard respectively, whilst the middle-line indication is given when both circles coalesce as shown in Fig. 4. Markerbeacon signals can also be distinguished according to whether they make the on-course circle shift vertically as shown in Fig. 6, or laterally. The signal circles are clearly distinguishable from atmospherics, and are formed without the aid of a time-base circuit.

Title: Improvements relating to atomic fluorescence spectroscopy
IPC: G01N21/64
Filed: 1969-04-29
Abstract: 1,263,290. Spectroscopic analysis. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. April 29, 1969 [May 1, 1968], No.21902/69. Heading G1A. A method of spectroscopic analysis comprises the step of forming an atomic vapour of a substance to be analysed by means of a discharge which causes sputtering of a sample 38 of the substance, illuminating the vapour by radiation including the spectrum of an element to be determined, and determining the intensity of resonance radiation emitted by the vapour as a measure of the amount of the element present in the substance. In the apparatus of Fig. 1, the sample 38 is mounted on a button 36 which screws on to a hollow water-cooled stud 34 projecting into, and electrically insulated from, a vacuum chamber 10. In use, the chamber is evacuated and argon is admitted. A gaseous discharge is then struck between an anode 32 and the sample pellet 38, and water flow from a pipe 44 is adjusted to maintain the sample at a constant predetermined temperature, measured by a resistance thermometer or thermocouple 42. Radiation from an atomic spectral lamp passes across the chamber through window 22, which may be coated or fitted with a broad band long wavelength filter material, and the resulting resonance radiation emitted by the atomic vapour is received by a photo-multiplier positioned outside a further window 22 which may also have an associated broad band filter. The photo-multiplier is arranged so as not to receive radiation direct from the lamp 14. The sputtering discharge is supplied from a D.C. supply and the lamp is powered from an A. C, supply, the output signal from the photo-multiplier being amplified before being fed to an indicator circuit including a meter. In a modification, the A. C. amplifier may be synchronized with the A.C. power supply. In a further embodiment Fig. 3 (not shown), the spectral lamp is powered from a D.C. supply (62) and the sputtering discharge is supplied from an A. C. supply (60) the timing of whose pulses is controlled by a trigger circuit (64) which also controls a gating circuit (66). In this way the photo-multiplier signal is passed to the output circuit only between pulses. In a modification, the power supply to the lamp may also be pulsed synchronously with the gating of the photo-multiplier signal. For the determination of a plurality of elements simultaneously, a number of lamps each emitting a different characteristic spectrum may be used, Fig. 4 (not shown) either simultaneously, in which each lamp is pulsed at a different frequency and each has a corresponding synchronous demodulator receiving the output from the photo-multiplier and detecting only its corresponding frequency, or sequentially, using just one synchronous demodulator responding to a common supply frequency to all the lamps.

Abstract: 921,140. Linear dimension gauges. BELL & HOWELL CO. June 23, 1960 [July 2, 1959], No. 21965/60. Class 106 (2). [Also in Group XXXVI] In a measuring device a conducting screw 41 has a thread 42 of the same pitch as the thread 114 of a nut 95 but has a smaller pitch diameter so that there is an air gap between the two threads, the nut having conductive ribbons 115, 116 which form capacitors with the thread 41, a bridge circuit with capacitors in different arms being used to show when the values of the capacitors are equal. A carriage 81 on which the object to be measured is located is moved longitudinally by a drive screw 17 rotated by means of gears 24, 71, 50 when handle 58 is turned. Sufficient backlash is left between the gears to allow screw 41 to be turned alone, after a point on the object to be measured has been aligned with the cross hairs on microscope 133, until thread 42 is aligned with that of a nut 95 formed of dielectric material. The threads 42, 114 of the screw 41 and nut 95 have the same pitch but different pitch diameters so that there is an air space between them. This air space together with thread 42 and conductive ribbons 115, 116 on thread 114 forms capacitors, a bridge circuit being provided with the capacitor in opposite arms to determine when their value is equal. The reading on dial 54 is taken. The carriage is then moved until another point of the object to be measured is aligned with the cross hairs of the microscope, the thread of screw 41 is re-aligned with that of nut 95 and the dial read again. A servo mechanism may be provided to align the threads.

Filed: 1974-05-17
Abstract: 1459629 Discharging hoppers KING-SEELEY THERMOS CO 17 May 1974 [28 Jan 1974] 21968/74 Heading B8S [Also in Division F4] An ice cube vending machine comprises a housing 12 including an ice storage bin 100 from which ice cubes are movable along a dispensing channel 160 to a dispensing cavity 210, and an ice transfer rotor 114 within the storage bin for selectively conveying ice cubes toward the channel 160 which is selectively blockable, control means being provided for operating the transfer rotor 114 independently of the channel blocking means to dispense cubes, or operating the rotor 114 together with the channel blocking means whereby the stored ice cubes are agitated without any dispensing taking place. The storage bin 100, which is supplied with ice cubes from an ice cube making unit within the housing 12 and above the bin, is formed from a mouldable synthetic polymeric material, with an upwardly inclined sidewall, 108 over which the rotor 114 is positioned, and an arcuate bottom wall 106 co-extensive with the lower part of the rotor 114 and extending into side walls 102, 104 substantially tangential to the rotor. The rotor 114 comprises a circular base 18 within an annular rim 116 and divided into sector pockets 122 by radial spokes 120, an aperture 134 being found formed in the base 118 and being associated with an L-shaped spoke portion 124, base portion 130 and cover 132 forming a scoop. The rotor 114 is normally positioned such that the aperture 134 is sited over a solid part of the housing wall 108 and upon rotating the rotor, the scoop gathers a certain volume of ice cubes which gravitate into the dispensing channel 160 as the aperture 134 passes over an aperture in the wall 108 communicating with the channel 106. The channel 106 is blocked during the agitation only operation by a plate pivotable into the channel under the control of a solenoid transmitting movement to the plate through a cable and pulley arrangement. The drive shaft from the motor 150 driving the rotor 114 incorporates a brake drum normally braked by a spring applied brake band which is released by solenoid action through a lever system when the rotor drive motor is energized. A single rotation of the rotor 114 when either a dispensing or agitating cycle is selected, is controlled by a cam disc mounted on the rotor shaft, which disc controls a switch for de-energizing the motor 15 and brake solenoid every time the rotor 114 reaches its normal rest position. Ice cubes dispensed into the cavity 210 are released therefrom by manual pull down against spring return pressure of a transparent door 206 which causes downward pivoting of the cavity base 218. Opening movement of the door 206 operates a switch to break the power supply circuit to the motor 150.

Abstract: 837,127. Code telegraphy. MAYNARD, P.C.G., and GATES, H. July 7, 1958 [July 16, 1957], No. 22452/57. Class 40 (3). A device for setting up a substantially invariable sequence of telegraph signals, such as the preamble to a telegraph message, comprises a hollow cylindrical member with a number of circumferential raised ridges and with a plurality of holes formed axially and circumferentially in the surface and adjacent the ridges for the location of members determining the code elements of some of the signals, and a portion of the peripheral material is removed to leave a gap in which a plurality of smaller cylinders, each adapted to be adjusted to represent code elements of further signals, can be positioned. As shown, the drum carries T-shaped code members C2 held by springs C3 in the holes and rotatable to occupy positions in which they straddle the ridges or are located in the grooves between the ridges so that their outer surfaces are flush with surfaces of the ridges. In a circumferential cut-away portion of the drum are mounted three rotatable cylinders C4, C5, C6 corresponding to units, tens and hundreds in the serial number of the message. These cylinders, which can be manually adjusted, carry axially arranged projections corresponding to code combinations for the numerals 0 ... 9 and respectively in alignment with the axial positions of the T-shaped member C2. The number cylinders are actuated during each complete revolution of the code drum C by the engagement of a pin on the unit indexing wheel with a projection on a fixed frame portion, and pins on the units and tens wheels engage pins on the tens and hundreds wheels to effect the requisite settings after ten steps of the units wheel and tens wheel respectively. The code drum has a toothed disc C1 carrying thirty-two teeth corresponding to the thirty-two signals set up on the code drum, and is advanced by one step by means of a cam-actuated pawl for each revolution of a control drum which has a control disc with seven sequentially arranged notches controlling the transmission of the start and stop elements and the selective operation of five sensing levers by the axially and selectively disposed projections on the code drum. The actuation of levers M rocks a bar K operating a member R3 engaging a knife-edge member S to rock a quick action contact member into engagement with one or the other of two contacts connected in a transmission line circuit. To initiate transmission a detent X is operated to allow a clutch W to effect rotation of the control drum G, and at or near the end of the preamble message a cam Y on the shaft of the code control drum C operates a microswitch Z to open the holding circuit of a coil controlling the detent X which releases and arrests the clutch member W.

Title: Improved manufacture of di-alkyl sulphates
IPC: C07C29/06
Filed: 1929-07-22
Abstract: 336,681. Etablissements Lambiotte FrÚres. June 25, 1929, [Convention date]. Dialkyl sulphates are obtained by causing the corresponding ethers to react with oleum, preferably in theoretical proportions and at temperatures below 50" C. Concentrated oleum is preferably employed. The crude product may be purified by distillation at ordinary or reduced pressures, and the sulphuric acid forming the residue may be used, either alone or mixed with fresh acid, in the production of further quantities of the ether by reaction with the corresponding alcohol. In one example, methanol is treated with sulphuric acid in a suitable vessel, and the ether produced is conveyed therefrom into a second vessel containing 60 per cent oleum, or into a column provided with suitable filling material down which the oleum trickles. The mixture of ether and oleum is cooled to 30‹ C. When all the ether is absorbed, the mixture is distilled, giving dimethyl sulphate. In another example, dipropyl sulphate is obtained in a similar manner starting with propanol. Specification 122,498 is referred to.

Abstract: 921,915. Sliver balling apparatus. WARNER & SWASEY CO. March 15, 1961, [April 28, 1960], No. 22499/62. Divided out of 921,914. Class 120 (1). The subject-matter of this Specification is identical with that described in Specification 921,914, but the claims are concerned with means sensing displacement of a sliver traversing guide from a predetermined ball-start position. The sliver traverse mechanism may be as described in Specification 917,072. During winding of the ball, the sliver guide member 38 reciprocated by an arm 41 is driven through gearing 47 and gears 50, 52. Gear 50 also meshes with a gear 135 on shaft 136 which is connected through an electromagnetic clutch with a motor operative during the doffing operation. Also fixed to the shaft 136 is a metallic electrically conductive control member 140, Fig. 9, having an insulated segment 142 set in the periphery of it. There is a unique position of segment 142 corresponding with the centre position of the guide member 38 and in this position a conductive plunger 143 is in contact with the segment and drive to the shaft 136 through the electromagnetic clutch is discontinued. With the plunger 143 in contact with the conductive periphery of the control member 140 the shaft 136 is driven. If a different system of gears were employed, the control member 140 could have two insulating segments. In other modifications the segments may be positioned to return the guide member 38 to any selected position. It is stated also that photo-electric or electromagnetic means may be utilized to sense the position of the control member 140.
