Title: Improvements in beam-type rail track brakes
IPC: B61K7/04
Filed: 1960-08-05
Abstract: 954,029. Railway track brakes. AUGUST THYSSEN-HUTTE A.G. Aug. 5, 1960 [Aug. 7, 1959], No. 27266/60. Heading F2E. In a railway track brake, brake beams 5 and 6 are situated one on each side of a rail of the track on a displaceable saddle 2, one brake beam 6 being mounted on a chair 6a slidable on the saddle 2 in a direction perpendicular to the line of the rail such that a wagon wheel " cutting open " a braking passage displaces the saddle 2 and brings the brake beam 5 into braking contact with the wagon wheel. In the embodiments shown in Figs. 1 and 3, the lefthand half shows the state of the brake when the wagon wheel 15 is braked while the right-hand half shows the state in which a wagon wheel 16 passes through freely. In the latter state the saddle 2 abuts against an abutment or stop 10 leaving a gap e between the inside of the wheel and the brake beam 5 due to the effect of the spring 12 in the case of the embodiment shown in Fig. 1 or, in the case of the embodiment shown in Fig. 3, the disposition of the swing supports 14. The width a is obtained by suitable retraction of the adjusting rollers 7. When the brake is set by advancing the adjusting rollers 7 and thereby the brake beam 6, the width a of the passage is then reduced to the width b<SP>1</SP> as indicated in the left-hand half of Fig. 1. The saddle 2 undergoes a displacement by the distance e when the passage is " cut open " by the wagon wheel and either the spring 12 is compressed or the swing supports 14 are erected. As soon as the wheel has passed the brake the width and position b<SP>1</SP> of the braking passage is readjusted immediately and the gap e shown in Fig. 1 at the stop 10 is then eliminated. An alternative embodiment is disclosed in the Specification wherein the saddles 2 are connected by means of a tension spring which fulfils the same purpose as the cup springs 12 in the case of Fig. 1, or the swing supports 14 in the case of Fig. 3.

Title: Titanium dioxide pigment
Inventor: LEDERER GERALD
IPC: C08K9/02
Filed: 1961-07-27
Abstract: Titanium dioxide pigment is made by a process of coating pigmentary rutile titanium dioxide with stannic oxide preferably 0.2 to 2% by weight of the pigment and thereafter heating the coated pigment to a temperature of at least 625 DEG  C., and preferably to 700-800 DEG C.  The pigment may also be coated with aluminium oxide and/or silicon dioxide.  A modification of the process consists of applying the coating or coatings to a sulphate process type pigmentary rutile titanium dioxide and after applying said coating or coatings and heating a further coating of aluminium oxide is applied to the pigment.  The examples, describe coating rutile titanium dioxide, in aqueous suspension, with stannic oxide alone, or together with aluminium oxide, or with a combination of aluminium oxide and silicon dioxide and subsequently heating to 750 DEG  C. for one hour and a further sample of rutile titanium dioxide pigment coated with alumina, silica and stannic oxide and heating to 625 DEG  C. for one hour; the above are compared with a pigment not according to the invention which is only coated with alumina titanium dioxide and silica as to discoloration on exposure to light when incorporated together with a melamine formaldehyde resin in a paper laminate. Specification 1,007,449 is referred to.ALSO:Pigmentary rutile titanium dioxide pigments coated with stannic oxide and optionally alumina and/or silica may be used for producing a pigmented thermo-setting resin for example a urea formaldehyde or melamine formaldehyde or phenol formaldehyde resin by admixture thereto, and curing the resin.  The pigment may be incorporated into a supporting material for example paper which may then be impregnated with the resin and finally the resin may be cured.  The pigment may be incorporated into a paper at the final beating stage in aqueous suspension and one or more sheets of the resulting paper containing the pigment are then impregnated with a thermo-setting resin as above and the sheets of paper thus per used are subjected to high temperature and high pressure conditions to cure the resin. Specification 1,007,449 is referred to.

Abstract: 1,095,142. Measuring pressure electrically. ULTRA ELECTRONICS Ltd. Oct. 12, 1964 [July 16, 1963], No.28038/63. Heading G1N. In a fluid pressure transducer the difference between a reference internal pressure of a capsule 1 (Fig. 1) and an unknown pressure within a capsule 3 causes deflection of a beam 2 pivoted at X. The deflection is sensed by a capacitive sensor having fixed plates 7 and a movable plate 4 attached to the beam and an electrical output therefrom is amplified. The rectified output of the amplifier energizes coils 8 of a force motor or actuator, creating a magnetic field which acts on a permanent magnet armature 5 attached to the beam to produce a counterforce on the beam in opposition to the force thereon due to the difference in pressures. The current supplied to the actuator coils is a measure of the differential pressure. The interior of reference capsule 1 may have zero pressure, and the two capsules are at the same external ambient pressure being within a sealed casing which may contain a silicon compound fluid. Expansion and contraction of the fluid due to temperature is taken care of by a multiple bellows assembly Fig. 2 (not shown).
