Title: Improvements in and relating to apparatus for testing lip seals
Inventor: JAGGER ERNEST THORNTON
IPC: G01M13/00
Filed: 1963-11-21
Abstract: 1,014,079. Testing lip seals. GEORGE ANGUS & CO. Ltd. Nov. 12, 1964 [Nov. 21, 1963], No. 45999/63. Heading F2B. In apparatus for testing the lip loading of lip seals and comprising a cylindrical surface member 1 diametrically split into halves 2, 3 mounted for relative movement perpendicularly to the split, the cylindrical surface of the member 1 corresponding in diameter to the surface to be sealed by a seal to be tested, actuating means for effecting and indicating the movement of the halves comprises a pneumatic load cell 16 having a thrust member movable by air at a controlled pressure, mechanical coupling means, e.g. a bell crank lever 8, for transmitting movement between thrust member and one half 3 of the member 1 and a pressure gauge connected to the cell to respond to air pressure change consequent on movement of the thrust member. In the arrangement shown in Fig. 1 for testing internal lip seals the member 1 is a hollow stub shaft mounted on a frame 4 the half 2 being fixed to the frame and the half 3 being movable on a guide 6. The lever 8 is pivoted at 7 and has an adjustable abutment 10 on one arm 9 that engages the movable half 3 while the other arm 11 bears against a boss 12 on the head 13 of a piston 14 slidable in a cylinder bore in the body 15 of the cell 16. A recess 17 surrounded by a flange 18 is formed in the top of the body 15 and compressed air which is supplied to the recess through a restrictor 23, passages 20 and duet 21 in the body can escape through the clearance 19 between the flange 18 and the head 13. The duct 21 is connected to a pressure gauge 22, Fig. 2 (not shown). According to the pressure of air supplied to the cell 16 the head 13 will stabilize at a given height and, in use, the pressure is adjusted so that the halves 2, 3 are separated by an amount to give an overall diameter, perpendicular to the split, equal to the nominal diameter of the part to be sealed by the seal 27 to be tested. The latter is then fitted on the member 1 and the resultant movement of the half 3 towards the half 2 decreases the clearance 19 with consequent increase in the air pressure which is indicated on the gauge as a measurement of the lip loading.

Abstract: 1501849 Recording apparatus; sonar systems RATHEON CO 5 Nov 1976 [25 Nov 1975] 46223/76 Headings G1G and G1J [Also in Division B5] In a chart recorder, e.g. for an echo sounder system, comprising means for supporting and moving a record medium 26, a stylus 50 for recording on the medium, and a transport arrangement 48 for the stylus comprising a belt 56 movable lengthwise of itself and carrying the stylus 50, the edges of the belt 56 are guided slidably in opposed slots 80 in a support 52, 54. The endless belt 56, having teeth 58 for a reinforced polycarbonate resin moulded on to a polyimide web coated on its non-toothed side with PTFE, passes round two sprockets 60 one of which is driven by a motor 62. The belt carries three stylus assemblies 76 equidistantly spaced apart, each assembly including a block 104 moulded integrally with a tooth 102 of the belt, and a channel member 108 bolted to the block. A tube 84 secured in the channel 108 slidably holds the stylus 50, which is urged towards the chart 26 by a spring 124. The assembly 76 is inclined at 5 degrees to a line parallel to the axis of the tooth 102 so that the top 120 of the stylus leads its point as it is moved across the chart. In a modified stylus assembly, Fig. 7, the tube 84 and a tube 170 on which to anchor the spring are moulded into the block 168. The chart 26 is drawn from a supply roll 28 having a drag brake 51, over a metal cylinder 44 and a roller 46, by a roller 31 driven by a stepping motor 36 and nipping the chart 26 against idler rollers 32. A take-up roll 42 is driven by a motor 38 through a slip clutch 40. The chart is of the kind in which a light-coloured surface layer is selectively burnt off by an electric spark, to expose parts of a dark coloured electrically conducting layer, to provide a permanent visible record. An electric potential is applied to the chart conducting layer via the cylinder 44, and to the stylus 50 via the support 52, 54, the lips 86, the tube 84. The belt 56 is driven continuously, a photo-electric sensor 128 on the support 52 providing a reference pulse to control circuitry as it is passed by each stylus 50. The sensor system, Fig. 6, includes a signal generator 138 driving a transmitting transducer 140. A receiving transducer 148 sends signals to a receiver 150 which filters and amplifies them. A correlator 156 receives signals from samples 152, 154 and a clock 158, and sends recording pulses to the recorder 20. Synchronizing pulses from the recorder 20 pass via line 129 to the generator 138. The samplers and correlator preferably are multibit units.

Title: Stabilisation of polyolefins and polyamides
Inventor: ASHTON STANLEY
IPC: C08K5/18
Filed: 1962-12-10
Abstract: Diphenylamine derivatives of the formula <FORM:1062628/C2/1> in which R represents a hydrogen atom or an alkyl or cycloalkyl group and A represents an acyl group derived from an aliphatic or cycloaliphatic acid containing at least 4 carbon atoms, are prepared by acylating the corresponding aminodiphenylamine with an appropriate acid chloride or acid anhydride.  Specified instances of the radical R are methyl, ethyl, isopropyl, cyclohexyl and methylcyclohexyl groups and specified instances of the radical A are the residues of butyric, pivalic, valeric, lauric, myristic, stearic, oleic, adipic, succinic, sebacic, capric and cyclohexane carboxylic acids.  The radical A may also be derived from a polycarboxylic acid and may contain chlorine atoms or cyano or alkoxy groups.  In an example, 4-aminodiphenylamine is condensed with lauryol chloride in the presence of pyridine to yield 4-lauroylaminodiphenylamine.  Other products similarly obtainable are 4-stearoylaminodiphenylamine, 4 - nonanoylaminodiphenylamine, 4- myristoylaminodiphenylamine, bis -(4 - diphenylamino) - adipamide and bis - (4 - diphenylamino) - sebacamide. The products are useful for protecting polyolefins and polyamides against oxidation (see Division C3).ALSO:As agents for protecting polyolefins and polyamides against oxidation, use is made of diphenylamine derivatives of the formula <FORM:1062628/C3/1> in which R represents an hydrogen atom or an alkyl or cycloalkyl group and A represents an acyl group derived from an aliphatic or cycloaliphatic acid containing at least 4 carbon atoms (see Division C2).  0.01-1% may be used. Specified instances of the radical R are methyl, ethyl, isopropyl, cyclohexyl and methylcyclohexyl groups and specified instances of the radical A are the residues of butyric, pivalic, valeric, lauric, myristic, stearic, oleic, adipic, succinic, sebacic, capric and cyclohexane carboxylic acids.  The radical A may also be derived from a polycarboxylic acid and may contain chlorine atoms or cyano or alkoxy groups. Specified products are 4-lauroylaminodiphenylamine, 4 - stearoylaminodiphenylamine, 4-nonanoylaminodiphenylamine, 4 - myristoylaminodiphenylamine, bis - (4 - diphenylamino)-adipamide and bis - (4 - diphenylamino)-sebacamide. The action of the products on polyolefins may be enhanced by the conjoint use of sulphides, e.g. dilauryl thiodipropionoate, phosphite esters, e.g. tris-nonylphenyl phosphite, phenyl dioctyl phosphite or trilauryl trithiophosphite, dialkyldithiophosphates, e.g. zinc diisopropyldithiophosphate, dialkyl dithiocarbamates, e.g. zinc dinonyldithiocarbamate, or ultra-violet absorbing agents, e.g. 2-hydroxy - 4 - octyloxy - benzophenone.  An example is given of the treatment of polypropylene, either alone or conjointly with dilauryl thiodipropionate.  An example is given also in which a solution of polyhexamethylene adipamide in formic acid is treated and then converted into a film. The polymer in powder or chip form may also be mixed with the antioxidant before spinning.

Liquid is filtered through a filter bed 2, the 'free liquid' surface being initially maintained above the top of the bed, and as successive layers of the bed become largely clogged the said surface is depressed to successively lower levels, below the top of the bed. Liquid is supplied to closed container 1 by a distributor 5, 6, and a series of air extractor pipes 7, 7a, 7b, 7c open at different levels, and are commoned to air extractor 9. Initially valve 8 is open, valves 8a to 8c closed, and air is carried in with the liquid and builds up to depress the liquid level to the lower end of pipe 7. When the upper layer of bed 2 is clogged, valve 8 is closed, valve 8a opened and air accumulates to depress the liquid surface to the end of pipe 7a, liquid trickling down through the clogged layer to that surface and being then filtered by the next lower layer. An air distribution system 10..3 serves to aerate the liquid during filtration and pipe lid, opening below bed-supporting base 4, is used for air/liquid backwashing. Various valves 8, 12 may be controlled manually or by a device 14 which responds to variations in differential pressure between layers in the filter bed.
