Abstract: 1,066,160. Selective signalling. MOTOROLA Inc. Nov. 11, 1965 [Jan. 25, 1965], No. 47909/65. Heading G4H. In a remote control system, for example for a crane, a sequence of eight pairs of tones, each pair being referred to as a " group," is transmitted, and the system is characterized in that of the two tones in each group one indicates the position that the group should occupy in the sequence, whereby a check, can be made that the tones have been received correctly. As described the tones are chosen from two sets of tones, a set of eleven (numbered 1 to 11) highfrequency tones and a set of seven (numbered 12 to 18) low-frequency tones and each group of tones comprises one from each set. The sequence of tones transmitted is divided into an address portion, Fig. 2, comprising the first three groups, and a main control portion, comprising the last five groups. The particular address shown in Fig. 2 is represented by low-frequency tones 1 to 3 (top row of Figure) each being associated with either tone 12 to 13 (bottom row) of the high-frequency tones. Also, as shown, the serial order of the main control groups (4 to 8) is determined by low-frequency tones 14 to 18 each of which is associated with one highfrequency tone chosen in accordance with the control to be effected. The entire sequence of eight tone groups is continuously repeated. At the receiver filters separate the tones and the following checks are made upon each sequence of eight tone groups before it has any effect: (1) the address is checked, (2) the serial order of the tone group is checked, and (3) each tone group is checked to see that it contains one high-frequency and one low-frequency tone.

Title: Control Circuit for Use with a Direct Current Dynamo-Electric Machine
Inventor: JACKSON ROBERT VERNON
IPC: H02J7/02
Filed: 1968-10-14
Abstract: 1,188,250. Starting prime-movers; batterycharging systems. McCULLOCH CORP. 14 Oct., 1968 [16 Oct., 19671, No. 48564/68. Heading H2H. [Also in Division G3] A control circuit, for use with a dynamoelectric machine, includes a battery which is used to drive the machine as a motor and which can also be charged to a predetermined voltage by the machine when operated as a generator. When this voltage is reached, a shunt winding of the machine is shorted to prevent overcharging of the battery. Current flow from the battery through the short is automatically prevented when the battery is connected so as to drive the machine as a motor. In the circuit shown in Fig. 2, the machine 20 is connected to a battery 22 through a diode 28, which may be by-passed by operating a switch 36 so that the battery voltage is applied to drive the machine and start an I.C. engine 24. The switch 36 is shown in the position where the machine is operating as a generator 2 charging the battery. The battery voltage is monitored by a circuit including Zener diodes 32, 33, and when the voltage reaches a predetermined level, current flows in a resistor 34 and triggers a thyristor 35 which shorts out the shunt winding 21 of the machine 20, and so reduces the generated voltage. To protect the circuit from excessive current which might arise if the diode 28 were by-passed while the thyristor 35 was gated on, the by-pass switch 36 is arranged to disconnect the thyristor and monitoring circuit at the same time as the circuit by-passing the diode 28 is made. Alternative ways of connecting the switch 36 are described with reference to Figs. 3 and 4 (not shown).

Title: Light sensitive reproduction sheet and method and coating composition therefor
IPC: G03C1/73
Filed: 1967-10-26
Abstract: 1,213,823. Photo-sensitive compositions. MANAGEMENT RESEARCH LABORATORIES Inc. Oct.26, 1967 [Nov.15, 1966], No.48774/67. Heading G2C. A light-sensitive composition comprises a coloured organic stable free radical and a free radical precursor which on exposure to light produces transient free radicals which react with the stable free radical to change its colour or bleach it. The composition may be coated with a binder on a support but one or both components may be encapsulated. On exposure the coloured material is bleached or changes colour in exposed areas. If a component is encapsulated, pressure is applied before, during or after imagewise exposure. The composition may contain a promoter for generation of free radicals. Specified stable free radicals are (a) hydrazyls, (b) verdazyls, (c) pyridinyls, (d) nitroxides, (e) aroxyls, (f) carbon free radicals and (g) ionic free radicals. Specified free radical precursors are (i) nitroaliphatics, (ii) p-t-aminoaromatics, (iii) halogenated hydrocarbons, (iv) quinones, (v) phototropic compounds, (vi) azo compounds, (vii) aryl disulphides, (viii) organic silanes, (ix) haloamides, (x) complexed halogens, (xi) organic N-nitroso compounds, (xii) aryl sulphone hydrazides and (xiii) substituted pyrroles. Specified promoters are aromatic aldehydes, ketones, ethers and sulphonamides nitriles, esters and unsaturated compounds. In the examples, the stable free radical (a picrylhydrazyl, a nitroxide, galvinexyl or a phenoxy radical), the free radical precursor (iodoform or chloroform) and optionally a promoter (anisaldehyde) or a sensitizer (1, 2- naphthoquinone) are dissolved in a toluene solution of ethyl cellulose and coated on a paper support and imagewise exposed to produce a coloured or bleached image. Alternative free radical precursors are mixtures of iodoform and either quinones or anthrones, mixtures of azo bis (isobutyronitrile) and quinones, anthrones or lophine, mixtures of tetranitromethane and an unsaturated acid, amide or a aldehyde, quinones or anthrones, polyvinylpyrrolidone-iodine complex, and a mixture of triallyloxyvinylsilane with N-methyl-N- nitroso-P-toluene-sulphonamide. The densitivity of the compositions may be extended to the visible range by adding dyes such as Patent Blue, thioflavine or Brilliant Green. An example of encapsulating a free radical, the precursor (tetranitromethane) and a promoter is given.

Title: Detect circuit
IPC: H04N1/327
Filed: 1974-11-12
Abstract: 1478416 Line transmission systems; facsimile systems; pulse circuits XEROX CORP 12 Nov 1974 [23 Nov 1973] 48962/74 Headings H4R H3P and H4F A signal detector includes a threshold circuit which in accordance with the level of an input relative to one or more threshold levels produces one of two output signals which via corresponding first or second paths controls charging or discharging respectively of a capacitor to which is connected control means responsive to a predetermined charge level on the capacitor, the two paths including oppositely poled diodes and a resistor. As described the detector is arranged to respond to start and stop tones for the control of a facsimile recorder or printer over a telephone line. The tones are demodulated to produce D.C. potentials which as shown are received at 10 via low pass filter R18, C5. If the amplitude of the resulting signal is below a threshold at 16 (set by divider R22, R23) comparator 15 produces a positive output from a source 18 which via resistors R26 and R28 and diodes CR5 and CR7 charges a capacitor C8 towards the positive potential. If due to a start signal of high amplitude, input 17 of comparator 15 exceeds input 16, the output of the comparator goes negative and capacitor C8 begins to slowly discharge via R27 and CR6. If the input persists or includes only short interrupts (e.g. is of long duty cycle) the capacitor C8 discharges to below earth potential causing comparator 25 to respond producing a negative output which via diodes CR9-CR11 turns on the recorder and via diodes CR4 and CR8 blocks path 22 to reduce the charging rate of capacitor C8 and switches the reference potential at 16 to a slightly negative value, thus preparing the detector to respond to a persistent negative D.C. input corresponding to a stop signal.

Title: Apparatus for measuring sheet properties
Inventor: FREEH EDWARD JAMES
IPC: G01N9/24
Filed: 1968-10-16
Abstract: 1,254,432. Measuring a sheet property. INDUSTRIAL NUCLEONICS CORP. Oct. 16, 1968 [Nov. 13, 1967], No.49173/68. Heading G1A. In an apparatus for determining a property e.g. basis weight of a running web wherein a gauge is scanned transversely across the sheet a succession of times, signals indicative of a function of the property values at different ones of a multiplicity of discrete longitudinal zones are accumulated for a plurality of scans, and output signals derived from the accumulated signals are displayed as a function of the cross sheet position, of the gauge in directions at right angles to each other. The output of traversing gauge 16, Fig.3, is applied to a profile averaging computer 42, and as it crosses the zones 3, 2, 1 of the sheet 11, to stores 54-56 in which outputs from the zones are accumulated. The output from computer 42 being applied at the end of each scan to an integrating store 47, 48 in response to the actuation of relay 51 by a micro-switch 46 operated by the scan. The stored signals are time weighted, being reduced by a timed insertion of a shunting resistor 67 in the case of store 48 and by a switched resistor 61 in the case of the zone stores, the switch being driven also by the gauge traversing motor but effecting a reduction in the stored signals in periods between the accumulation periods. The weighted signals from stores 54-56 are sequentially subtracted from that in store 48 in an operational amplifier 75 and the differences are accumulated in further stores 82-84. These accumulated values, or an interpolation of them produced across a resistor 91, are compared with the transducer instantaneous values in a further operational amplifier 45 and may be indicated as a measure of machine direction basis weight on indicator 39 or used to effect retroactive control of the property at the point of sheet production, or the interpolated values may be applied as an indication of cross direction basis weight to a display recorded 97 also driven by the gauge traversing motor so that an operator may effect manual control. The arrangement is said to eliminate random, variations, and a further embodiment in which binary signals produced from the transducer output by an analogic to digital converter are processed in a similar manner in a digital computer is discribed with reference to Figs.4 and 5 (not shown).

Filed: 1968-10-18
Abstract: 1,214,049. Drying slurries. IMPERIAL CHEMICAL INDUSTRIES Ltd. 9 Oct., 1969 [18 Oct., 1968], No. 49476/68. Heading F4G. A band drier is fitted with slurry streaking means at the feed end of the drier before entry to the heating section 5 of the drier, said streaking means being employed to impose a pattern on the wet slurry so as to wholly subdivide the wet slurry into a plurality of discrete sections which are removable as separate dried sheets or strips from the discharge end of the drier, or to partially subdivide the wet slurry into a plurality of weakly connected sections which are readily separable at the discharge end of the drier. The said streaking means take the form of a first set of lateral streaking members 14 mounted for reciprocating motion across the drier for effecting lateral streaks at spaced intervals across the width of the wet slurry, and a second set of longitudinal streaking members 9 and 8 for effecting longitudinal streaks along the length of the wet slurry. The lateral and longitudinal streaking members are of such length as to either completely subdivide the slurry for its entire depth without damaging the band of the drier, or to effect depressions in the slurry which produce tear lines in the dried sheet. The lateral streaking members are soft tipped elongated finger members mounted at spaced intervals on a driven endless belt disposed across the drier. The longitudinal streaking members are similar and mounted at spaced intervals on the hopper fulcrum bar 7 so as to be raisable and lowerable with the feed hopper 2 of the drier, positioned between the entry to the oven section of the drier and the point of application of the slurry to the band of the drier. The longitudinal streaking members may be mounted so as to subdivide the slurry before it leaves the reverse roll coater 3 from which the slurry is applied to the band of the drier 1, or the slurry division may be achieved using a driven embossed roller mounted across the width of the drier in such a manner as to impose a pattern on the slurry.

Filed: 1963-12-14
Abstract: 1,107,366. Disc brakes. DUNLOP CO., Ltd. 7 Dec., 1964 [14 Dec., 1963], No. 49481/63. Heading F2E. A disc brake comprises a rotatable disc 1, a caliper housing 8, a friction element 14 mounted for movement relative to the housing into frictional engagement with the disc, an actuating mechanism including a pressure plate 15, and means attaching the element to the plate comprising a resilient bush 19, having outwardly extending end flanges introduced into axially-aligned holes in the element and plate. The housing is pivoted by bolts 10 to links 9 which are themselves pivoted by a bolt 7 passing through a tube 5 secured to an arm 3 of a torque-taking support member 2 attached to a non-rotatable part of an axle casing thereby permitting the housing to move bodily in direction substantially parallel to the axis of the disc without tilting. Rubber or fibre bushes 11 inserted between the pivot bolts and the links prevent rattle and reduce brake squeal. The arm 3 has flat guide surfaces 4, perpendicular to the disc which the inside faces of the housing abut to transmit the braking torque thereto. Substantially rectangular friction elements 12 and 14, including metal backing plates 29 and 18 respectively, are located either side of the disc, the element 12 being bolted at 13 to one leg of the caliper. The other element 14 is connected at its radial inner edge to the pressure plate 15 by a spring clip 17 riveted thereto, and, at its radial outer edge by the bush 19 which is longitudinally slotted at one end, Fig. 4 (not shown). A detachable pin 25, passing through holes 26, bush 19 into a blind bore 27, prevents rotation of the friction elements on brake application and permits their removal radially outwards through the aperture 16. The element 14 is applied to the disc by a piston 24 working in a detachable cylinder 23, the other element 12 being applied by reactive movement of the housing. Alternative applying means, comprising a Bowden cable actuating links 32, 36 and 37, pivot the link 37 about a forked fulcrum member 38 secured, preferably through rubber bushes or springs, to a stabilizing arm 39 fixed to the support member 2. The member 38 is located at the end of a bolt 41 forming part of a wear adjustment means 42 described in Specification No. 1,090,756. The piston and cylinder may be provided with an automatic retraction mechanism of the type described in Specification No. 850,649.

Title: A process of recovering strontium,cesium,cerium and rare earth values from radioactive solutions
IPC: G21F9/12
Filed: 1963-12-16
Abstract: Caesium values are extracted from an aqueous solution by adjusting the pH of the solution to between 3 and 14, contacting the aqueous solution with an organic solution of a water-immiscible phenol and a water-immiscible alkyl ester of phosphoric acid in a water-immiscible aliphatic hydrocarbon or halogenated hydrocarbon so that the caesium values are extracted into the organic solution, and separating a caesium-rich organic phase from a caesium-poor aqueous phase.  The aqueous solution may be a nuclear fuel waste solution, an ore solution or a brine.  The phenol may be 4-sec.-butyl - 2 - (a  - methyl - benzyl)phenol (BAMBP), and the alkyl ester of phosphoric acid may be di-2-ethylhexyl phosphoric acid (D2EHPA); other suitable phenols and alkyl esters of phosphoric acid are listed in the Specification.  The aliphatic hydrocarbon solvent preferably is a kerosene fraction.  As exemplified, caesium may be extracted from an aqueous solution having a pH of 10.5 by an organic solution which is 0.5 M in BAMBP and between 0.006 M and 0.1 M, preferably 0.05 M, in DZEHPA.  The aqueous and organic solutions, which preferably are both at a temperature of 10 DEG  C., may be contacted either in a batch process or in a continuous column operation, the volume ratio of the aqueous and organic solutions preferably being unity.  The aqueous solution may also contain strontium, cerium and other lanthanide rare earth values; if these metal values are to be coextracted with the caesium values, the pH of the aqueous solution should be adjusted to between 3 and 5, both the aqueous and the organic solutions preferably being at a temperature of 35 DEG  C.  For such coextraction, the organic solution preferably is between 0.15 M and 1.0 M in BAMBP and between 0.2 M and 0.4 M in D2EHPA, a molar ratio for BAMBP to D2EHPA of 5 to 3 being preferred.  The metal values, after separation of the organic and aqueous phases, may be recovered from the organic phase by back extraction with a mineral acid, for example nitric acid.  Using acid of pH 1.5, caesium and strontium are back extracted and may be separated by known methods, for example by passage over a cation exchange resin; using acid of pH below 1 or between 5 and 6, the cerium remaining in the organic phase is back extracted.  Alternatively, extraction of an aqueous solution containing caesium, strontium and cerium values may take place in two stages, strontium and cerium first being extracted into a first organic solution relatively weak in the phenol component, and then, after separation of this first organic solution from the aqueous solution, caesium being extracted into a second organic solution relatively strong in the phenol component.  Reference is made to Specification 1,013,473 and to U.S. Patent 3,154,500.
