Title: Process for the condensation of sulphonic acids
IPC: C07C309/51
Filed: 1947-11-19
Abstract: Tanning, wetting and emulsifying agents are prepared by condensing aromatic sulphonic acids with a compound which contains in the molecule an active methylol group and an amino group, and which has been made from urea or thiourea and ammonia condensed together with an aldehyde in acid solution.  As sulphonic acids are specified b -naphthalene-, propyl-naphthalene-, and lignin-sulphonic acids, and those products prepared from alkyl-naphthalene sulphonic acids having wetting and emulsifying properties.  In an example, formalin, and ammonium sulphate are heated together in solution at 70 DEG  C., urea is slowly added, and the mixture kept heated for several hours.  b -naphthalene sulphonic acid is then added to the resinous product and the mixture heated at 100 DEG  C., and then, after cooling, neutralized wholly or partly with ammonia, caustic soda, AR(OH)3, Cr(OH)3, or by buffering.  In a modification, a phenolic, urea, or other synthetic resin free of sulphonic groups may be included in the reaction mixture.

Abstract: 427,045. Drying rubber sheets; heating by circulation of fluids. NISBET, E. G., and DREW, A. L., 23, Austin Friars, London.-(Socfin Co., Ltd.; Bungsar Estate, Kuala Lumpur, Selangor, Federated Malay States) Nov. 7, 1933, No. 30987. [Classes 34 (ii) and 64 (ii)] Rubber sheets are dried by heat treatment, first in a stage of lower temperature and then in a stage of higher temperature. Water may be allowed to drip off the sheets before drying, and the rubber may be smoked while dripping or during the first drying stage. In the form shown, the rubber is stacked on trucks, which are left in the dripping shed for about 6 hours. The trucks are then passed into a drying shed 5, which is provided with steam pipes 7 and a smoke inlet 9. A draught is maintained by means of ventilators 11 and inlet ducts, and a suitable drying temperature is 100-120‹ F. The final drying is carried out in an unventilated shed maintained by steam pipes at a temperature of 140-180‹ F. The arrangement of the steam pipes is shown in Fig. 5, two series of pipes being provided in the higher temperature shed, so that steam is passed into and withdrawn from the pipes 14 at both ends of the shed ; the used steam is then passed into both ends of the series of pipes 7 and withdrawn at the middle. Thus in both drying sheds the heat generation is greatest when the heat losses are greatest. Specification 138,915, [Class 64 (ii)], is referred to.

Title: Device for controlling the working of the hydraulic brake system of automobiles
IPC: B60T17/22
Filed: 1953-11-10
Abstract: 741,461. Hydraulic brakes. COLOCOLOFF, M., and COLOCOLOFF [nee STEWART], L. Nov. 10, 1953 [Aug. 31, 1953], No. 31044/53. Class 103 (1). [Also in Groups XXXI and XXXVII] The invention relates to a device B for fitting to the cover-plates or filler caps of reservoirs of hydraulic master cylinders for automobile brake systems for warning the driver if the brake fluid level should fall dangerously low. As shown in Fig. 1, the device comprises an earthed metal tube A secured to the top of the reservoir by nuts L and M and containing a contact carrying member E adjustably secured on a rod D. When the liquid level falls substantially, a metal float I makes contact between the contact member E and the tube A, as shown in Fig. II, so that a warning lamp is operated in front of the vehicle driver. So that the driver may know that the lamp is effective it is also operated by the rise of brake fluid that takes place at each brake application by contact between the float I in the upper position shown in Fig. II. To increase this rise in fluid the bottom of the cylinder A is fitted with a funnel-shaped flange X. In the arrangement shown in Fig. VI, the float I1 has an end conductor I2 which in the low liquid level position closes a circuit between conductor rods D and R, the tube A being in this case of non - conducting material. Several other possible forms of float-operated switches are described. In Fig. XIII a circuit for a warning lamp C is shown in which the lamp, as well as being operated by the float control switch, is also illuminated if any of the vehicle doors K1, K2, K3 and K4 are not properly closed. The lamp C may be such as is described in Specification 739,744, [Group XI].

Abstract: 621,563. Universal joints. GARVIE, M. Nov. 20, 1945, Nos. 31123/45 and 22602/46. [Class 80 (ii)] In a universal joint of the kind wherein coupled shaft-ends 20, 21 coact with a drive-transmitting intermediate member, such as a block 22, to prevent axial separation and maintain a constant intersecting point of the shaft-axes and their swivel-axes, one shaft-member 20 carries a sleeve 23, in the internal cylindrical surface of which bears a spherical surface on the other shaft-member 21, or on the intermediate member, with line contact only, the contact-line lying in a transverse plane of the sleeve which is constant in all positions and contains the intersecting point of the shaft-axes and of their transverse swivel axes. In Figs. 2 and 6 the intermediate block 22 is rectangular in transverse section and has cylindrical cross-sections in two axial planes at right-angles for swivel engagement in transverse cylindrical bores in the bifurcated shaft ends 20, 21, the block being entered laterally into the bores, after which lateral separation of the shafts is prevented by sliding over the sleeve 23 and pinning it to the shaft 20. The sleeve 23 is externally spherical, to coact with a socketed casing-member 32. In Fig. 7 a cylindrical intermediate member 22 swivels in a transverse cylindrical bore in the shaft 20 and has a flat-sided slot receiving a tongue 21e on the shaft 21, the tonguebeing pinned to the member 22 by a central - swivel -pin (not appearing in Fig. 7). The ends of the intermediate member,22 are spherical to bear with constant line-contact (as above referred to) in the cylindrical sleeve 23. In Fig. 10, the shaft 20 terminates short of the joint, the intermediate member being a transverse bar 28, the cylindrical ends of which bear directly in the external sleeve 23, whilst. its flat-sided intermediate part is embraced by the forked end of the shaft 21 and retained therein by a pin 29 introduced through a screw-plugged opening 31 in the sleeve 23. The forked end of the shaft 21 is externally spherical for constant line-contact (as above referred to) with the cylindrical sleeve 23.

Abstract: 324,627. Robertson, H. M. Oct. 26, 1928. Annealing-furnaces; air, preventing admission of.-In an annealing-furnace having a plurality of waste-gas outlets spaced along the lower portion thereof, the supply of fuel and rate of exhaust are reduced, after initial heating-up and prior to cooling, to produce and maintaining a " soaking " temperature, and a non-oxidizing atmosphere is maintained in the working-chamber by returning to the upper portion some or all of the combustion products taken off at the lower part. The invention is described in connection with a pair of furnaces 4 each fired by a pulverized-fuel burner extending through an opening 14 into the combustion chamber 12, the waste-gas outlets 19, 19<a> being uniformly spaced along the lower part of the side walls and communicating with vertical flues 18. The latter deliver into main flues 17 extending along the upper parts of the side walls and connected to a manifold 22 from which conduits 23, 23<a>, 24 lead to the inlet of a motordriven exhaust fan 25. The outlet of the fan delivers to a chimney 30 with which communicates a main 33 having branches 32 passing through the roofs of the annealing-chambers 4. Dampers 34, 35, 36 are provided in the pipe 24, chimney 30, and main 33 respectively. Each vertical flue 18 is provided with a damper 18<1> which is suspended by a chain 37 passing over sheaves 38, 39, 40 and connected to a notched operating-handle 41, the latter being held in any adjusted position by the engagement of the notches over the edge of an aperture in a vertical plate 43. As shown in Fig. 1, all the dampers 18<1> of a chamber 4 are independently operable from a single station. To prevent any air which may enter through the charging door 16 from obtaining access to the working chamber and also to ensure a sufficient supply of heating gases at this point, the flues 18 adjacent the door 16 are connected by a conduit 20 arranged below the floor level and covered by a grating 1<a>.
