Title: Tyre pressure warning systems
IPC: B60C23/04
Filed: 1971-11-10
Abstract: 1373637 Tyre pressure indicating systems CHRYSLER UNITED KINGDOM Ltd 2 Oct 1972 [10 Nov 1971] 52193/71 Heading B7C A tyre pressure indicating system comprises a pair of switches 24, 25 mounted in spaced apart positions on a vehicle part 27 rotatably mounting a wheel 10 carrying a pneumatic tyre 12, a tyre pressure responsive device mounted on the wheel 10, and a switch striker 22 operatively connected to the pressure responsive device whereby, in use, when the tyre pressure is at a predetermined level, the device positions the striker such that in its rotation with the wheel it passes between the switches 24, 25 at a point equidistant from each switch, but if the tyre pressure rises above, or falls below, this level by a given amount the device moves the striker 22 such that in its rotation with the wheel it strikes and operates the switch 24 or 25 respectively thereby to actuate a warning device, e.g. of a visual and/or audible nature. The given amount by which the pressure must change before the striker 22 operates the switch 24 or 25 is determined by the distance of each switch from the striker when the latter is in the position it assumes at the predetermined pressure level, and, in order that the given amount may be altered, the switches may be adjustably mounted on a corner 26 secured to the part 27. In one embodiment, Figs. 1, 2, the pressure responsive device comprises a hollow cylinder 13 divided into two chambers by a slidable piston 18 which has a seal 19 and is connected to a rod 20 carrying the striker 22 the right-hand chamber (as seen in Fig. 2), being open to the tyre pressure through a tube 16 and a member connected to, and holding open, the tyre inflation valve 17, and the left-hand chamber being vented to atmosphere and containing a spring 23 which opposes the tyre pressure in the right-hand chamber and thus determines the predetermined pressure level referred to above. The cylinder 13 has an externally screw-threaded hollow spigot 14 through which the rod passes and by means of which and a nut 15 it is secured to the wheel. The pressure responsive device of Figs. 1 and 2, may be modified (see Fig. 3, not shown), by containing the pressurized air from the tyre in a flexible bellows (30) located in the right-hand chamber of the cylinder 13, in which case both chambers of the cylinder are vented to atmosphere and the piston seal is omitted. A further form of pressure responsive device is shown in Fig. 4, wherein a hollow casing 31 replaces the cylinder and a flexible diaphragm 32 is provided instead of the piston.

Abstract: 1,242,222. Valves. INTERNATIONAL TECHNICAL SERVICES Ltd. 6 Nov., 1968 [17 Nov., 1967], No. 52422/67. Heading C2V. Within the chamber 11 of a flow control valve 10, there is disposed a moulded, elastomeric material tubular member 12 whose configuration is such that at each of its ends it has a cylindrical portion 24, between its ends a central portion whose axial extent is delimited by the arrow 14, and between each end portion and the central portion an intermediate portion the axial extents of which are delimited by arrows 17 and 20. In the absence of any forces acting on the tubular member 12, both the central portion and each of the intermediate portions has a somewhat flattened elliptical shape in a plane perpendicular to the valve rectilinear axis 43, with the major axes of such elipses lying perpendicularly to the plane of the drawing. As depicted in Figs. 3 and 5 (not shown), the shape of each intermediate portion varies along the axis 43, with the major axis increasing in length from the adjacent cylindrical portion towards the central portion and the minor axis simultaneously decreasing in the same direction. The valve is closable by a pinch member 30 which co-operates with a chamber wall 28 and is openable, upon the withdrawal of the pinch member, by fluid pressure acting on the central portion. In modifications, the valve axis 43 may be other than rectilinear, with the relationship between it and the changing configuration of the tubular member being made to correspond to that outlined above. The pinch member may be made of two synchronized parts and the pinch member operator handle 36 may be substituted by any mechanical equivalent or by a pneumatic jack.

Abstract: 1406217 Measuring displacements electrically NATIONAL RESEARCH DEVELOPMENT CORP 8 Nov 1972 [16 Nov 1971] 53149/71 Heading G1N A linear displacement transducer comprises a series of parallel conductors 10, Fig.1, connected to a 3-phase A.C. supply to produce a linear developed 3-phase magnetic field, in which is located a base plate 18 carrying two elongate coils 14, 16 with their long sides arranged parallel to the magnetic lines of force. Hence no EMF is induced in these sides and the EMF's in the end parts are neutralized by connecting coils 14, 16 in series. A loop 20 of magnetic material is disposed round the adjacent long sides of coils 14, 16 and is skewed so that it extends diagonally between two adjacent conductors 10. Thus a current is induced in coil 20 which induces a voltage in coils 14, 16, whose phase is indicative of the position of coil 20 within one pitch of six conductors 10. The coil 20 is attached by a rod 26 to a test member whose longitudinal position is therefore indicated by the phase of the voltage in coils 14, 16. Other embodiments are described using a different magnetic member 20 and a single coil 14, 16.

Abstract: 1,160,629. Condensates of melamine, formaldehyde and cyclic diamides. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Nov., 1967 [26 Nov., 1966], No. 53501/67. Heading C3R. [Also in Division D1] A resin is obtained by condensing at least one compound containing the group -NHCO-NH- once or the group -NH-CO- twice in a five- or six-membered ring with melamine and formaldehyde and at least one monohydric water-soluble alcohol, until the product is insoluble in neutral aqueous media, but soluble in 1 to 3 wt. per cent aqueous phosphoric acid and in methanol. Preferably the ratio, by weight, of melamine to heterocyclic compound lies in the range 3 : 97 to 50 : 50, and the formaldehyde is used in the proportion of 6 moles per mole of melamine plus 0À5-2 moles per mole of heterocyclic compound. Suitable heterocyclic compounds include imidazolidone- 2; hexahydropyrimidone - 2; glyoxal monoureine and its dimethyl ether; 5-hydroxy-, 4 - methoxy - 5 : 5 - dimethyl - , 5 - methyl-, and 5 : 5 - dimethyl - hexahydropyrimidone 2; 5 - methyl - and 5 - # - hydroxyethyl - 1 - hexahydrotriazinone - 2; and 2 : 5 - diketopiperazine. Suitable alcohols are methanol, ethanol and propanol. The heterocyclic compound and melamine may be condensed in neutral or alkaline aqueous solution, or in alkaline solution in the alcohol, then etherified in acid solution in the alcohol, and neutralized when the required viscosity (thread-formation on cooling) is reached. The products have solids contents of 40-70 wt. per cent and viscosities of 50-1600 c.p.s. at 20‹ C.; they are soluble in methanol, ethanol, dimethylformamide, dimethylsulphoxide and dilute aqueous acids, e.g. 1-3% H 3 PO 4 , 1-3% HCl and 1-5% maleic acid. The solutions may also contain dimethylol derivatives of the above hexahydropyrimidones or 5 - isopropylhexahydrotriazinone-2. For finishing textiles, acid aqueous or polar solvent solutions containing 2À5-10 wt. per cent of resin at pH 1À5-3 are used. In examples, imidazolidone-2, and/or hexahydropyrimidone - 2 and/or glyoxalmonoureine or 1 - isobutyl - 3 : 5 - dimethyloltriazinone - 2 or 4 - methoxy - 5 : 5 - dimethyl- 1 : 3 - dimethylol - hexahydropyrimidone - 2 or N : N<SP>1</SP> - bismethoxymethyl - urone is condensed with melamine and formalin, then with methanol, ethanol or propanol, to give solutions of density 1À07-1À14 g./c.c., viscosity 75-1522 c.p.s. at 20‹ C. and solids content 46-68%.

Filed: 1974-12-12
Abstract: 1495717 Information protection HONEYWELL INFORMATION SYSTEMS Inc 12 Dec 1974 [12 Dec 1973] 53772/74 Heading G4A In a data processing system in which a memory stores in address spaces having adjustable boundaries information of different types, an effective address ring number EAR representing the maximum level of privilege for a selected address is developed, this being the maximum of a base register number BRN which is a predetermined level of privilege associated with the address space and a process ring number PRN which is the level of privilege associated with the address space assigned to the currently executing process. To determine whether reading, writing or executing in an address space is permitted, read, write and execute ring numbers RD, WR and MAXR are examined, an exception occurring unless WR, RD#EAR# MAXR unless RD = PRN since a procedure may always read its own segment. The system operates in a multi-programming, multi-processor environment and has four levels of privilege, the inner ring 0 having the most privilege and the outer ring 3 the least. A procedure belonging to an inner ring has free access to data in an outer ring but cannot branch to a procedure in an outer ring. Conversely a procedure in an outer ring cannot access data in an inner ring without a protection violation exception occurring and can only branch to a procedure in an inner ring by executing a procedure call instruction which results in a stack frame being formed within a stack segment (one stack segment corresponding to each protection ring per process) to store variables and contents of registers. In operation an instruction counter contains an address syllable field representing the segment number and offset within the segment of the next instruction, a two bit tag specifying direct/indirect addressing and whether the next storage location contains further information and a two-bit PRN field representing the ring number of the current process. The address syllable in the instruction word includes the number of a base register in which is stored a segment descriptor address in the form of a segment table number STN, a segment table entry STN and an offset, the ring number associated with the segment and a two-bit tag. If the addressing is indirect it may extend to up to 16 levels with a EAR being computed at each level. Two-bit registers are provided to hold the ring numbers and permit the necessary comparison operations to be effected.

The arrangement 10, 12 may comprise two separate devices as shown or a single three-step action element comprising. adjustable threshold devices providing an output depending on the sign of the difference frequency when it exceeds a predetermined value. For varying the frequency of the input pulse train to the counter 6 in dependence upon the difference frequency, a voltage to frequency converter is included in generator 8, the input voltage of which is provided by a controller 20 which compares signals representing the desired and instantaneous output frequencies. During a change of the counter reading, a memory .circuit maintains the previous division ratio of divider 3. The counter may be uncoupled from the generator 8 when the frequency difference is zero and the signals representing the counter reading are applied to the divider 3.

Abstract: 1428118 Welding by fusion CLARKE CHAPMAN Ltd 22 Nov 1973 [25 Nov 1972] 54551/72 Heading B3R [Also in Division B4] A self-centring clamping device capable of introduction transversely of workpieces, such as bars or tubes, comprises a gapped body 10 accommodating a workpiece, three angularly spaced jaws 14, 16, 18 each having a multistart scroll formation and slidably mounted in the body so as to be movable into and out of clamping engagement with a workpiece, a gapped scroll-plate (38) mounted in the body and having three multi-start scroll formations permanently engaging respective jaw scroll formations, and means to turn the scroll plate and thereby move the jaws comprising a hand wheel or screw or, as shown, one or two racks 42 engaging a gapped gear (36) attached to the scroll plate. As shown, the racks 42 are actuated by air admitted to cylinders 48 via a three-position valve 50 operable by a lever 52. The jaws are two-start and have keys 24 engaging slide keyways 30 in the body. One of the jaws, viz. 18, near the body gap has a greater width than that of the other two jaws to ensure adequate scroll engagement overlap since only short scroll formations are available for engagement therewith. The scroll formations are "fast", providing 0À125 inch jaw travel for 11 degrees scroll plate movement. The clamp is intended to support an orbital welder (such as described in Specification 1428120. Two clamping devices, e.g. joined by U-shaped frame, could be provided to engage tubes on opposite sides of a tube joint. Other applications include: cutting out damaged tubes from an array (e.g. in heat exchangers), preparing (e.g. grinding) tube ends for welding, aligning tubes for welding, inspection (e.g. of welds) by orbital appliances such as ultrasonic or X-ray, and friction weld flash removal.

Abstract: 1469849 Testing DC sources K S CHAMPLIN 19 Dec 1974 [2 Jan 1974] 54920/74 Heading G1U The capacity of a D.C. source e.g. primary, secondary battery, fuel cell, solar cell or thermoelectric device is measured as in Specification 1396359, Division Gl, by determining the 'dynamic power' which is proportional to the A.C. conductance of the source. A lead-acid cell of voltage V o  and internal resistance R s  is connected via one twisted-pair conductor to the inputs of a differential amplifier A1 via a variable source of A.C. e o (t). The amplifier output is sensed across Rl by a second amplifier A2 with a milliammeter in its feedback path. The magnitude of i 2  can be shown to be proportional to |e o lÀK(T) and DPR/R2, where K(T) is the variation of capacity with temperature Fig. 1 (not shown) and D.P.R. is the Dynamic Power Rating, which may be replaced by the Cold Cranking Current Rating or the AmpÚre- Hour rating. Thus by setting |e o | in accordance with battery temperature and R2 to the nominal capacity, the meter indicating i 2  can be calibrated in percentage capacity. A full circuit diagram for Fig. 3 is given in Fig. 5 (not shown) where the meter is D.C. and the second amplifier A2 is supplied with power only in alternate half-cycles of the A.C. source e o , thus providing synchronous detection enabling a D.C. meter to be used. The meter itself has a fail/pass indication on its scale Fig. 4 (not shown) or the display may be only lamps indicating the test result. In the Fig. 1 (not shown) embodiment a constant current source i o (t) is connected across the battery and the voltage developed across it is amplified and indicated  directly. This voltage is inversely proportional to the capacity and thus is not so convenient an indication. Reference has been directed by the Comptroller to Specifications 1320409 and 1396359.
