Abstract: 1490191 Metal detector PLESSEY CO Ltd 16 Jan 1975 [23 Oct 1973] 49174/73 Heading G1N A metal detector operative according to the pulsed eddy current principle comprises a probe 1, a pulse drive circuit 2 for supplying pulses to the probe, a preamplifier 5 responsive to signals received by the probe, first signal sampling circuit 7 connected in a feedback loop 6 of the preamplifier for sampling the signals fed from the preamplifier just prior to the initiation of each drive pulse, the sampled signals being used for feedback purposes to stabilize the preamplifier, and a second; signal sampling circuit 8 for sampling signals fed from the preamplifier to provide signal samples in dependence upon which an indication of the presence of metal in the vicinity of the probe is provided. The probe may include a coil for transmitting a pulse signal and a coil for receiving signals deriving from eddy currents induced in metal objects in the vicinity of the probe. Alternatively one coil may be used for both purposes. The coil may be an open frame coil or a winding or windings carried on a ferrite core. The drive pulses may be produced under the control of signals from a timing circuit 3, which may comprise an appropriate gating circuit fed from a control pulse generator 4. The sampling circuits 7, 8 are operated under the control of gating signals from timing circuit 3. The circuit 8 is arranged to sample signals at some time after the probe has been pulsed, these signals being averaged and fed to main amplifier 10, which has a feedback loop 11 and integrator 12 associated with it, the function of the latter being to stabilize the amplifier so as to reduce sensitivity to drift. Output signals from the amplifier 10 are fed to a voltage sensitive pulse generator 15 which feeds an acoustic transducer 16. The integrator may be switched to provide a number of alternative time constants. A switch 14 may be provided for battery checking purposes. Various types of probe may be used depending upon the application of the detector. For example, probes of 20 cm. length may be used for inspecting contents of mail, and probes of 1m. length may be used for searching terrain. A probe in the form of a large diameter sledge coil may be pulled or towed behind a vehicle. Smaller diameter coils may be sewn into the palms of gloves for search purposes. The detectors may be mounted on a wooden vestibule or gateway for searching personnel and luggage. The detector is stated to be an improvement or modification of that described in Specification 1390606.

Title: Isocyanate-terminated adducts and the treatment of leather therewith
IPC: C14C9/00
Filed: 1965-11-22
Abstract: An isocyanate-terminated adduct is prepared by reacting a diisocyanate of the formula <FORM:1101924/C3/1> where n is 3 or 4 and R is an alkyl radical of 8 to 20 carbon atoms with castor oil or a polyol of average molecular weight is at least 700 and whose ratio of the number of carbon atoms to the number of hydroxyl radicals is at least 15, the NCO/OH ratio being 1.3:1 to 2.0:1.  The diisocyanates may be prepared by esterifying ornithine or lysine with an alcohol ROH which products are then phosgenated.  Lysine diisocyanate octyl ester is the exemplified diisocyanate. The polyols may be branched or straight chain polyethers, hydroxy terminated polyesters derived from "Dimer Acids" and castor oil.  The adducts may be mixed with an agent which acts as an emulsifying agent when the mixture is stirred with water to form an emulsion or the adduct and the emulsifying agent may be stirred independently into water to form an emulsion, which emulsion may be used for the treatment of leather (see Division C6). Suitable emulsifying agents are ethylene oxide adducts of substituted phenols, sodium lauryl sulphate, non-ionic alkylated aryl polyether alcohols and sodium N-methyl N-oleo taurate.ALSO:Leather is treated, to improve its "break", "temper" and scuff resistance, with an aqueous emulsion of an isocyanate-terminated adduct prepared by reacting e.g. in an atmosphere of nitrogen, a diisocyanate of the formula:  <FORM:1101924/C6-C7/1> Where n is 3 or 4 and R is an alkyl radical of 8 to 20 carbon atoms, with castor oil or a polyol having an average molecular weight of at least 700, and in which the ratio of the number of carbon atoms to the number of hydroxyl radicals is at least 15, the NCO/OH ratio in the reaction mixture being 1.3:1 to 2.0:1 (see Division C3).  The emulsion may also contain an emulsifying agent. Examples describe the impregnation of leather with an emulsion containing an isocyanate-terminated adduct prepared by reacting lysine diisocyanate octyl ester with castor oil or a diol, triol or tetrol.  The emulsifying agent may be an ethylene oxide adduct of t-octyl phenol, sodium lauryl sulphate, a sodium salt of a long-chain fatty acid, a non-ionic alkylated aryl polyether alcohol or sodium N-methyl, N-oles taurate.  The treated leather is dried in an oven at a temperature of 40 DEG C., and then subjected to conventional plating.

Title: Spray droplet analyzers
IPC: G01N15/00
Filed: 1969-10-15
Abstract: 1,245,319. Counting apparatus; selective signalling. PARKER-HANNIFIN CORP. 15 Oct., 1969 [19 Nov., 1968], No. 50677/69. Headings G4D and G4H. The performance of an atomizing nozzle is evaluated by automatically counting into size ranges the number of droplets in successive small regions of the spray produced by the nozzle. The test is repeated, e.g. 100 times, for each small region and the results are analysed statistically. The droplets within each small region 24, Fig. 7, are isolated from the rest of the spray 22 by illuminating the spray with a flash of light from a xenon tube 11, by optically focusing an image of the region 24 under consideration on to a videcon tube 12, the depth of focus only being sufficient to cover the region, and hence images of droplets in front or behind the region will be blurred, and by differentiating the resulting video signal, since only those droplets which are in focus will produce sharp, small rise-time, signals. Once a particular region has been examined the nozzle 21 is moved to a new position 21a so that a further region can be examined. Droplets sizing is effected by scanning the image on the videcon tube with a normal raster-the image produced by one flash being arranged to persist long enough for a complete scan-examining every line of the resulting video signal and every time a droplet is detected looking at the same position of the next line to see if the droplet extends over two lines, and so on. In this way the number of horizontal raster lines over which each droplet extends can be determined. These are sorted into six size ranges, a correction for non-linearity is made, and the number of droplets within each range is recorded, together with data indication the position of the nozzle, on punched tape, for subsequent analysis. The recording could take place during a blank scan of the videcon to give it time to recover. The required non-linearity correction is determined experimentally using transparencies of reference droplets, and is effected as follows. Having decided in which size range a given droplet lies on the basis of the number of raster lines over which it extends, a group of pulses is entered into a counter corresponding to that size range. The number of pulses within each group is such that larger size ranges receive proportionally less pulses to effect the required correction. The complete apparatus, shown in Fig. 1, includes a spray chamber 4, a xenon lamp 11, a videcon tube 12, a three dimensional nozzle positioning system, for which a conventional control circuit (Fig. 6, not shown) is outlined, and a data processing system which both determines the sequence of regions to be examined and accepts and processes the results obtained. Within the spray chamber spray is prevented from landing on the videcon lens by arranging for a jet of air to pass across it (Fig. 2, not shown).

Title: Vehicle speed detector for use with a skid control system
IPC: B60T8/172
Filed: 1971-11-08
Abstract: 1343354 Anti-skid braking systems NISSAN MOTOR CO Ltd 8 Nov 1971 [16 Nov 1970] 51806/71 Heading F2F [Also in Division G1] In an anti-skid system for controlling the braking of a wheel of a moving vehicle, the angular speed of the wheel is measured electrically and the brakes are released when the deceleration reaches an upper pre-set value and re-imposed when the subsequent acceleration reaches a pre-set value, the switching being also dependent on the difference between the angular speed of the wheel and a corresponding nominal vehicle speed whose value is adjustable in accordance with the coefficient of friction between the wheel and the road surface. As shown (Fig. 1), the angular speed of a test wheel of a vehicle is measured at 12. The speed signal is fed to a unit 34 which develops a corresponding vehicle speed signal and adjusts the setting of a unit 42 in accordance with the coefficient of friction Á of the road surface. When the brakes are applied the wheel deceleration is determined at 14 to produce a first input to AND gate 20 when the deceleration exceeds a pre-set value. At the same time the vehicle speed signal is compared at 48 with the wheel speed signal to produce a second input to gate 20 when the difference exceeds a predetermined value. AND gate 20 then produces an output signal which is one input to AND gate 24 and produces an output signal on line 32 which releases the brake pressure. The angular speed of the test wheel increases and when its acceleration reaches a pre-set value, unit 26 removes the second input to gate 24 and its output is cut off, allowing the brakes to be restored. This process is repeated until the vehicle speed is zero. The Á- detector 42 is automatically adjusted in accordance with the duration of the output pulses from gate 24. The vehicle speed signal generator 34 comprises a capacitor C1 (Fig. 3) charged by the wheel speed signal via diode D1, and discharged via resistors R1, R2 and transistors T1 at a constant rate I when T1 is made conductive by an output signal from gate 24 when the brakes are applied. It is shown that the potential at junction X represents the vehicle speed. The Á- detector 42 controls the discharge current I by varying the current through transistor T5 and lamp L, controlling the resistance of resistor R1, which is made of photo-resistive material.

The reservoir section 2 and the mould cavity 4 may also be partly defined by stationary side members 6. In the embodiment shown the mould is supported by hydraulic jacks 12 and may be used to form an ingot 11 of greater height than itself. As the ingot builds up mould members 5 are removed from the bottom of the mould and placed in their spaced apart positions on top of the reservoir section 2, and the parts of the mould members defining the lowermost portion of the reservoir section are moved inwardly to the positions in which they define the cavity 4. The jacks 12 are raised as the members 5 are removed from the bottom of the mould. The parts of each mould member 5 may be connected to a water main (16) via flexible hoses (15) and a rotatable manifold (17) Fig. 4 (not shown) and the mould may be constructed so that a plurality of ingots can be produced simultaneously, Figs. 5 to 8 (not shown). Moulds for producing ingots which vary in cross-section along their length, e.g. ingots in the form of a roll having a plurality of passes, or a crankshaft, are also described, Figs. 10 to 12 (not shown). In these embodiments there is no removal of mould members from the bottom of the mould but as the ingot builds up the height of the reservoir section is decreased and that of the ingot-shaping section increased by moving the mould members 5 from their spaced apart positions to their adjacent positions.

Title: Device for spreading material for increasing the frictional properties of road surfaces
IPC: E01H10/00
Filed: 1976-12-15
Abstract: Salt or sand increases the grip on icy traffic areas. The device serves for distributing such materials. The material distributor of the device has at least two rotating distributor plates (6, 6') arranged one above another, with outwardly directed throwing rails (4, 5). The distributor plate (6) mounted at the top has in each case a smaller diameter than the plate (6') mounted below it. The distributor plates (6, 6') are covered by a hood (1). The material slides from the fall-in shaft (11) onto the uppermost distributor plate (6). By means of the rotation of the distributor plates (6, 6'), a part of the material is thrown out laterally. A further part is diverted by a deflection plate (7) onto the lower lying distributor plate (6'), from where it is thrown over a larger radius. The throwing effect can be increased by a central opening in the lower distributor plate (6'), which causes a draught (13) on rotation of the plates (6, 6'). The material can be moistened, in order e.g. to increase its adhesive strength, by spray liquid (8) from spray nozzles (3). <IMAGE>
