Filed: 1974-03-30
Abstract: 1492044 Adjusting vehicle headlamps LUCAS ELECTRICAL Ltd 17 March 1975 [30 March 1974] 14218/74 Heading F4R In an arrangement for tilting vehicle headlamps about a horizontal axis in response to changes in attitude of a suspended part of the vehicle, means for sensing such changes includes lever 16 pivotally mounted at 17 on a suspended part of the vehicle and, in the operative condition of the assembly, biased by spring 21 into engagement with member 23 mounted on the wheel axle, and manually operable means is provided for moving lever 16 out of engagement with member 23 to render the tilting mechanism inoperative, e.g. when the headlamps are switched off. As shown, switch 39 which when closed energizes the lamp filaments, also supplies current to heating element 34, causing fluid 35 to extend, bellows 35 to contract against the bias of spring 40 and accordingly in the operative condition stop 36 does not abut arm 37 of lever 16. When the lamps are switched off, contraction of fluid 35 causes stop 36 to engage arm 37 and rotate lever 16 out of engagement with member 23, the effect of spring 40 overriding that of spring 21. Member 23 may be the output rod of a sensor of a temperature compensating means as disclosed in Specification 1,485,831.

Filed: 1975-04-07
Abstract: 1483824 Synchronous detector circuit GRUNDIG EMV 7 April1975 [31 July 1974] 14223/75 Heading H4L In a high speed synchronous detector circuit for separating a selected one from a plurality of amplitude modulated TDM signals and for use as a colour signal demodulator in a colour TV system, the components of the required signal in the multiplex have superimposed thereon periodic rectangular pulses having an amplitude appropriate to shift the required component into an amplitude range distinct from that of the other components. The resulting components are supplied to a holding circuit comprising a diode 33 and capacitor 34 through an impedance converter 27, 26. The holding circuit has an associated discharge circuit connected across the capacitor 34 comprising resistor 36 in series with a transistor 37 which is controlled by gating pulses having the same periodicity as the rectangular pulses. The value of resistor 36 is such that the voltage on the capacitor after the discharge is lower than any possible value of the resulting signal components. In order to avoid the distortion which may result from the holding and switching operation, the output from the detector circuit, at 35, may be passed to a second similar circuit 41 which is switched (at 138) at a later time than the first, such that the output is held during the switching time in the first circuit.

Title: Improvements in an apparatus for the analysis of a chemically purified water
IPC: G01N27/416
Filed: 1935-05-16
Abstract: <PICT:0443403/III/1> <PICT:0443403/III/2> Apparatus for determining the quantity of oxidizing agent in excess in a chemically purified water comprises a couple formed of dissimilar metals immersed in the water to be analyzed, each member of the couple being formed by a large number of electrodes arranged very close together, a measuring apparatus for indicating variations in the E.M.F. of the couple, which variations depend on the excess of oxidizing agent present, and a device for ensuring a constant supply of the water to be tested between the electrodes of the couple.  In the arrangement shown, the couple 9 consists of anodes of a metal such as zinc or cadmium, susceptible to attack by an electrolyte, and cathodes of a polished metal, such as copper or tin, capable of causing overpotential with hydrogen, all the anodes and cathodes being respectively in parallel to terminals 13, 12 connected through a voltmeter or milliammeter 17 and variable resistance 18 to a source 15 of constant E.M.F.  The purified water to be tested is admitted by a pipe 1 to a tank 2 connected, near its base, by a pipe 4 with a second tank 5 containing the couple 9, the rate of flow of water through the tank being maintained constant by overflow pipes 3, 6.  In making a test, the circuit is first adjusted until no current flows through the milliammeter 17 when the couple is immersed in water not containing excess of oxidizing agent.  The current flowing through the milliammeter when the purified water to be tested is passing through the apparatus is then directly proportional to the excess of oxidizing agent in the water.

Title: Improvements in or relating to facsimile and like communication systems
IPC: H04N1/193
Filed: 1946-05-13
Abstract: 613,961. Copying telegraphy. SADIRCARPENTIER. May 13, 1946, No. 14448. Convention date, May 31, 1945. [Class 40 (iii)] A facsimile or like communication system in which signal impulses are sent in trains, each of which includes also a pilot impulse, comprises at the transmitter an impulse source, a delay line connected thereto, a plurality of pick-up devices each associated with a different tap on the line and an impulse output circuit connected to said line and at the receiver a delay line, means for feeding delayed pilot impulses to one end of said line, means for feeding the remaining impulses to the other end of the line and a plurality of recording circuits each associated with a different tap on the line. At the transmitter, a plurality of photo-electric cells 15 (Fig. 2) each scan a longitudinal strip of a message tape, each cell 15 being connected to a corresponding point in a delay network 14. At predetermined equally-spaced intervals a generator 13 feeds an impulse into the network 14 which therefore gives rise to a reflected wave at the impedance discontinuity caused by the connection with each cell 15. The reflected pulses are evenly spaced, or contiguous, and the amplitude of each is a function of the instantaneous resistance of the corresponding photo-electric cell 15, i.e. a function of the brightness of the image being scanned by that cell. An input resistor 29 reflects an initial pilot impulse of amplitude greater than any signal impulse and the network 14 is terminated by its characteristic impedance 17 in order to prevent any reflection from that point. The impulses from the generator 13 received directly by the line amplifier 18 are suppressed therein, by amplitude discrimination. The reflected signal pulses modulate a carrier wave or are transmitted as D.C. pulses. At the receiver the signals are demodulated, if necessary, and the pilot impulses separated out in any suitable device 20, retarded at 21, and fed into one end of a delay network 22, into the other end of which are fed the signal impulses. At the point in the network 22 where a signal impulse meets its pilot impulse their voltages add up to operate a corresponding relay 26 and record the received signal on a tape, moving in synchronism with the transmitter tape. The pilot impulses may be used to obtain this synchronism and transmission may be by means of mechanical or other reading means.

Title: Process for the production of phenols
Inventor: BEWLEY THOMAS
Filed: 1961-04-22
Abstract: <PICT:0930161/IV(a)/1> <PICT:0930161/IV(a)/2> In a process for the production of phenols and by-product ketone by the acid catalysed decomposition or alkaryl hydroperoxides superheating of the surface layer of the reaction mixture and the gas phase above is minimised by condensing vaporized ketone and intimately premixing and diluting the alkaryl hydroperoxide within the reaction vessel with the recycled stream of condensed ketone before contact with the acid reaction mixture.  The premixing of the hydroperoxide and ketone may be effected by causing jets of the liquid reactants to impinge in the gas phase above the reaction mixture, or to impinge on an open surface, e.g. a plate positioned above the reaction mixture, or on the sides or roof of the vessel itself.  In a preferred embodiment shown in Figs. 1 and 2, premixing is effected by introducing the hydroperoxide and ketone into the reaction vessel through two separate coaxial sparging rings of different radii.  The ketone is preferably fed into the larger sparging ring 2 from line 1 and the hydroperoxide into the smaller sparging ring 3 from line 4.  A stream of ketone and a stream of hydroperoxide are fed through holes 5 and 6 provided in rings 2 and 3 respectively into radially sloping troughs 7.  The streams become suitably admixed as they flow down the trough and the mixture is discharged into the reaction mixture below.  The reaction may be carried out at 50 DEG  to 90 DEG C.; at atmospheric or under reduced pressure and employing between 0.05 and 10% by weight based on the total weight of reaction mixture of acid catalyst.  The hydroperoxide may be utilised in the form of pure hydroperoxide or in the form of a crude oxidation mixture containing the hydroperoxide.  The invention is described by reference to the sulphuric acid-catalysed decomposition of cumene hydroperoxide to give acetone and phenol.  Specification 684,039 is referred to.

Abstract: 707,654. Preparing fibres for spinning; stapling fibres. SOENENS, M. June 20. 1951 [June 27, 1950], No. 14685/51. Classes 120(1) and 120(3) Spinnable fibres are obtained from long stems of flax, hemp, jute &c. by rippling the stems or fibres and laying them in parallel order, and conveying them to juxtaposed groups of conveyer belts superimposed in pairs, the stems or fibres being seized by the belts and cut into shorter pieces by members situated between the belts, the pieces thus obtained being broken or crushed and subjected to the action of combined scutching and hackling devices while they are held by the same belts, and the fibres obtained thereby being finally condensed into a form suitable for spinning. As shown, Fig. 2, flax, hemp or like fibres or stems are fed transversely by a conveyer 1 to rippling-machine consisting of a pneumatic wheel 2 and belt 3 which draw them through combs 6. Thence the stems or fibres, of a length e.g. of one metre, are fed by an apron 7 to upper belts 8, 9, 10, 11 which co-operate with lower belts to clamp the fibres or stems at spaced points, each lower belt engaging in a recess in the outer surface of the corresponding upper belt. The stems or fibres are carried by the belts past cutting discs 9 which may be saw-toothed and which cut the stems or fibres into shorter sections each of which is gripped by one of the pairs of belts and carried past pairs of plain and toothed crushing rollers 21, 22, 23 and a bladed scutching device 24. The stems or fibres are then transferred to a second set of belts 25, 26, 27, 28, laterally offset from the first set, which carry them past a second set of crushing rollers 33, 34, 35 and scutching devices 24<SP>1</SP>. Each scutching device comprises blades 133, Fig. 6, and hackling members in the form of adjustable combs 135 the teeth of which are concave towards the direction of motion. On leaving devices 24<SP>1</SP>, the scutched fibre is carried forward on a conveyer 42 which converges on belts 25-28; compressed air is blown into the gap between conveyer 42 and belts 25-28 to cause each sheet of fibres to narrow so as to form, on leaving the belts, a thin sliver which is delivered into a rotary pot 48. As a modification, the scutching devices may be of the double, instead of the single, acting type.
