As shown, the pressure of a vehicle tyre 11 is monitored, a switch 17 being closed, when the pressure falls below a predetermined level, to close the circuit between coils 19, 20. Coil 24 is connected to an amplifier 31 and integrator 32 whose output energizes a relay coil 33 to cause a switch 29 to change over to energize a buzzer 27 instead of a lamp 28. In a modification, Fig. 3 (not shown), the amplifier and integrator are replaced by a pulse trigger circuit and a monostable multivibrator and amplifier circuit. Instead of a switch 17, a sensor may be provided to control the current flow between coils 19, 20. For example a positive temperature coefficient resistance semi-conductor may be used to sense the temperature of the tyre. The indicating means may then be a meter.

Title: Disazo dispersion dyestuffs containing a urethane group
IPC: C09B31/02
Filed: 1965-12-23
Abstract: The invention comprises disperse dyestuffs (free from SO3H and COOH groups) of the formula <FORM:1099097/C4-C5/1> wherein R represents an alkyl, cycloalkyl, aralkyl or aryl radical, R1 represents an alkyl, aralkyl or aryl radical, R1 and R2 represent aryl radicals, R3 represents an aromatic-carbocyclic or -heterocyclic or aliphatic radical in which the OR4 group is in the adjacent or p-position to the azo grouping, and R4 represents H or alkyl.  The dyes may contain non-ionic substituents.  They may be obtained by either diazotizing an aminoazo compound of the formula: ROOC-NR1-R1-N = N-R2-NH2 and coupling with an enolic or phenolic coupling component in an adjacent or p-position to the OH group, or treating a dye of the formula: R1HN-R1-N = N-R2-N = N-R3-OR4 with a haloformic ester of the formula: hal-COOR wherein 'hal' represents a halogen atom.  The resulting dyes may be alkylated. Suitable enolic and phenolic coupling components are those of the phenol, naphthol, 5-pyrazolone, acylacetic acid amide and hydroxyquinoline series.  Examples are given for the production of the dyes.  They may be used for dyeing or printing hydrophobic materials.  Aminoazo compounds of the formula: ROOC-NR1-R1-N = N-R2-NH2 are obtained by diazotizing an aminoarylurethane of the formula: ROOC-NR1-R1-NH2 and coupling with an arylamine of the formula R2-NH2.  Diazo dyes of the formula R1HN-R1-N = N-R2-N = N-R3-OR4 are obtained either by diazotizing a compound Acyl-NR1-R1-NH2, coupling this compound with a coupling component R2-NH2, diazotizing the product, coupling this compound with an enolic or phenolic coupling component R3-OH and hydrolysing the acylamino group either during the course of the process or afterwards, or by coupling a diazo compound of an amine of the formula HO-R3-NH2 with an aminoaryl compound R2-NH2, diazotizing and coupling the product with an amine R1-NHR1.ALSO:1 - Amino - 4 - N - carbomethoxy - N - methylaminobenzene is obtained by reacting 1-N-methylamino -4-nitrobenzene with chloroformic acid methyl ester at 50 DEG  C. in dimethylaniline and dioxan, giving 1 - nitro - 4 - N - carbomethoxy - N - methylaminobenzene, and reducing this intermediate with H2 and Raney Ni in methanol giving the required product.

Abstract: 1529059 Transfer passages in IC engines RICARDO & CO ENGS (1927) Ltd 18 Dec 1975 [18 Dec 1974] 54633/74 Heading F1B A two stroke I.C. engine having a cylinder 10 with transfer ports controlled by a piston 14, the ports being at the ends of transfer passages 12A, 12B from the crank-case 13 to the cylinder 10, the ports being opened when the piston reaches a predetermined point on its working stroke, at least one but not all of the transfer passages having a gas pressure responsive valve 15 to control the flow of gas through the passage. The valve may be a non-return valve of the reed type and is lightly biased to the closed position so that flow through the valved passage or passages does not occur until the pressure in the crank-case exceeds that in the cylinder by a predetermined amount. At low loads with part throttle flow occurs only through the unvalved transfer passages but at full throttle flow occurs through all the transfer passages. The valves may alternatively not be capable of complete closure but may instead move from a more flow restricting position to a less flow restricting position when the predetermined pressure difference is reached.

Abstract: 1279544 Display devices INTERNATIONAL BUSINESS MACHINES CORP 20 Nov 1970 [30 Dec 1969] 55178/70 Heading G5C A display device (Fig. 1A) comprises a member 2 containing a groove, electrodes 6, 7 on either side of the groove, a vane 1 including electrically conducting material mounted in the groove and means for applying potentials to the electrodes to bend or turn the vane to a selected side. The electrodes 6, 7 are covered by high resistance films 4, 5 and another electrode 8 in contact with the vane extends at right angles to electrodes 6, 7. The faces of the vane have contrasting appearance e.g. black and white or highly reflecting and dull. Films 4, 5 have the same appearance as the adjacent faces. Potentials of 400 V, 400 V and 200 V. are applied to electrodes 6, 7, 8 to maintain the vane against one of the films e.g. 4. To move the vane the potentials of electrodes 6, 8 are reduced to zero resulting in the potential on electrode 7 moving the vane to film 5, reducing the potential on electrode 6 or 8 alone does not move the flag. To maintain the new position the original potentials are re-applied. If the vane was already against film 5 its position is not affected. The position of the vane is sensed by applying a pulse to electrode 8, and a read out pulse is received on the electrode against which the vane rests. Alternatively a pulse on electrode 6 or 7 will generate a pulse on electrode 8 only if the vane is against that electrode. The switching speed can be increased by covering the device with a transparent conducting cover at 400 V. The vane is biased to a vertical position by a magnet in the base 3 if the vane is of magnetizable material e.g. video tape coated with a conducting layer of colloidal graphite. Alternatively (Fig. 1C) the vane is flexible and clamped between curved parts 2a, 2b of the body. The devices form part of a matrix display.

Abstract: 1312096 Automatic level control ECODYNE CORP 20 Nov 1970 [21 Nov 1969] 55310/70 Heading G3R The level of solid ion exchange, resin in a separation column is controlled by an inlet valve operated by an ultrasonic signal sensing device. In a mixed-bed ion exchange system for demineralizing water, mixed ion exchange resins are removed from a service column and supplied through a conduit 30 to a separation column 10, Fig. 1. An upward flow of water from an inlet 16 to an outlet 18 causes the less dense anion exchange resins 22 to rise relative to the cation exchange resins 20 so that they may be removed separately through conduits 26, 28 for re-generation. If the upper level of resin rises to occupy a gap between the transmitter and receiver of a high frequency ultrasonic unit 40, an electrical signal is applied through a controller 34 to close a valve 32 electrically, mechanically or hydraulically for predetermined periods until the level falls. Gain is adjusted so that the system does not respond to 'fines' 24. In a modification, a signal corresponding to the level is derived from the time taken for ultra-sonic radiation to be reflected from a transmitter to a receiver by the upper surface of the resin. In this arrangement, which may be temperature compensated, valve 32 may be controlled in a proportional manner.

[Also in Division F2] A device for preventing extension of a safety belt includes a reel 8 biased by a spring 9 to wind in the belt 6 and a pair of levers 12 pivoted to side plates 1 and 13 and carrying a rotatable roller 14 about which the belt freely passes in normal circumstances. The levers are biased to the solid line position by the spring 9 but when the belt reaches a predetermined acceleration the levers pivot and a pawl 15 carried by one of them engages with a ratchet wheel 11 secured to the reel. Thus the increase in the bias applied to the lever 12 compensates for the increase in the tension of the belt 6 as more of the belt is unwound from the reel and ensures that the reel is always locked by the pawl 15 at approximately the same acceleration of the belt. In the embodiment shown in Figs. 1 and 2 the compensating arrangement is applied to the device for preventing extension of a belt set forth in the parent Application.

When the main flow is deflected into, e.g., duct 20 some of the flow passes to outlet 32 at pressure OP 1  and the remainder passes through a conduit 36 tangentially into vortex chamber 30 to establish a vortex therein. Some of the vortex flow passes along duct 22 to vent 26 at pressure Pr and the remainder passes to outlet 34 at a pressure OP 2  somewhat lower than the vent pressure Pr, thereby establishing a relatively high-pressure difference (OP 1 -OP 2 ). The conduit 36 can be arranged to choke at sonic velocity when conveying compressible gas. In an alternative embodiment, Fig. 2 (not shown), only the duct (22) is provided with a vortex chamber, the latter being connected to the duct (22) via a short convergent nozzle (42).
