Title: Process for the polycondensation of the ethylene glycol diester of terephthalic acidin the molten state
IPC: C08G63/81
Filed: 1954-07-29
Abstract: Polyethylene terephthalate is made by heating the ethylene glycol diester of terephthalic acid in the molten state and passing through the melt the vapour of a paraffin hydrocarbon or an aromatic or hydroaromatic compound which contains no functional group.  Specified are the vapours of paraffins with 9-15 carbon atoms, benzene, toluene, xylene, cyclohexane and decahydronaphthalene.  The polycondensation may be effected continuously by passing the melt down through a reaction vessel in a series of liquid filaments while passing the vapour stream upwardly through the vessel.  The product discharged from the bottom of the vessel may be recycled or passed through a similar vessel.  In examples, dimethyl terephthalate was trans-esterified with ethylene glycol in presence of a zinc/boron trioxide catalyst and the resulting ester bulk polycondensed at 250-270 DEG  C. with vigorous stirring while passing a stream of benzene, decahydronaphthalene or cyclohexane through the melt. Specification 578,079, [Group IV], is referred to.

Title: Improvements in or relating to relays for electric protective systems
IPC: H02H3/26
Filed: 1923-09-04
Abstract: 225,616. Reyrolle & Co., Ltd., A., and Lulofs, W. Sept. 4, 1923. Protective arrangements ; electromagnetic switches.-In a balanced protective system in order to prevent faulty operation of the differential relay when heavy line currents are flowing due for instance to inequalities in the current transformer characteristics, this relay comprises two solenoids placed at an angle with their cores so connected to the contact arm that for a given difference between their energizations the angular movement of the contact arm is less with larger currents than with small. As shown in Fig. 1, solenoids A, A<1> fed from transformers at the ends of the potential line are placed at right-angles, their cores B, B<1> being pressed outwards by springs C, C'. The solenoid cores terminate in perpendicular slotted guides D, D<1> embracing the ends of a pin E<1> carried by a sleeve E slidable along the contact arm F. The arm F is pivoted at G and carries bridging members G' adapted to co-operate with the fixed relay contacts H, H'. Thus when solenoids A, A<1> are only slightly energized, the distance of the pin E<1> from the first G is smaller than when heavy line currents are flowing and the degree of unbalance required to produce the necessary angular movement of the contact arm is consequently greater with larger currents than with small. The solenoids may be so disposed that the position of the cores may be controlled by gravity, and for three-phase working three such relays may be employed. In Fig. 2 the windings of the solenoid A are in two portions A<2>, A normally acting in conjunction and fed from transformers K, K' at the ends of the line. This relay comes into operation even if a fault occurs in such a position that the feeder is fed with equal currents from each end, in which case the windings A<2>, A<3> would oppose each other.

Title: Improvements relating to the separation of free liquid from masses of loose solid material
IPC: B01D21/06
Filed: 1956-07-23
Abstract: 836,424. Filters ; gravity-separation apparatus. STAMICARBON N.V. July 23, 1956, No. 22746/56. Class 46. [Also in Group XIII] From a feed trough 5, Fig. 1, kept charged with the material to be treated, material flows continuously onto a stationary table 1, preferably imperforate but optionally wholly or partly perforate, over which move two series of scrapers 2, 2<SP>1</SP>, Fig. 2, mounted respectively on endless chains 3, 3<SP>1</SP>. The material is thus urged towards a slot 6, and during its progress liquid gravitates from the upper layers C to the lower layers B of the mass. On reaching the slot 6 the lower layers B pass into it, the upper layers C passing on over the far edge 6a of the slot 6. A plate 7 having a downwardly-stepped portion 9 underlaying the slot is adjusted longitudinally so that the inclination to the horizontal of an imaginary line 14 joining the end of the portion 9 to the slot edge 6a is always greater than the angle of repose of the lower layers B (the latter angle being a function of the water content of the layers). Material discharging through the slot is returned to feed by a pump 13. In Fig. 3 an endless belt 17 is moved in the direction of the arrows, the bed being divided at the edge 19a of a plate 19 parallel with the bed and preferably adjustable vertically. In Fig. 4 a flat perforate screen 21 is connected to the delivery end of the wet screening apparatus 22 of any of the Specifications 791, 520, 791,857, 791,858 and 791,859, on to which material to be treated, e.g. water and fine coal, is tangentially fed at 23. Most of the water together with part of the fine product is collected in a tank 24, the residue passing on to the screen 21 where it slides down until checked by a plate 27a rotatable about a shaft 26 parallel to the screen 21 but spaced from it by a gap 28. Water sinks through the bed, some of it dripping through the screen perforations into a shoot 29 and tank 30. The plate 27a is adjusted so that its free edge 36 is sufficiently below the sloped surface 37 of the bed A to allow discharge, over that edge, only of material having a moisture content below the required predetermined value. Wet material in the lower part B of the bed passes through slot 28 and slides over a plate 27b, pivoted on shaft 26, into the tank 30. The setting of plate 27b (independent of 27a) determines the minimum water content of material passing over it. In a modification the water passing through screen 21 is discharged separately at 35 above a wall 34.

Filed: 1930-07-29
Abstract: 354,537. Stropping-apparatus. AKTIEBOLAGET ORYG, Gothenburg, Sweden. July 29, 1930, No. 22876. Convention date, July 9. [Class 60.] A safety-razor of the-pivoted blade type is provided with a stropping mechanism such that stropping is effected without altering the position of the razor relative to the fixed parts of the mechanism and without removing the blade from the razor. The razor is of the kind having a strop-engaging friction roller 10 connected by toothed or friction gearing 7, 8 with a shaft 4 pivoted in a forked part 2 of the razor, and on which is mounted a holder 5 carrying a blade 6. The holder may be adapted to take other forms of blades or knives. The stropping mechanism comprises a sheet-metal box 21 in which the razor is held rigidly by clips 31, 32. Stropping is effected by longitudinal movement of the lid 22 which has side runners 25 engaging the turned over sides of the box. A strop-carrying plate 27 is pressed downwards by transverse leaf springs 28 secured to the plate or struck up from either the plate or lid, and is caused to move with the lid by projections 30 engaging one of the springs 28 and by the turned down end 29 of the lid which end also limits movement in one direction of the lid. Alternatively the springs 28 may be omitted and the plate 27 rigidly mounted on the lid 22 in which case the razor is pressed upwards by a clip embracing the upper part of the handle and carried on a transverse leaf spring fixed to the bottom of the box. The blade may be caused to perform a transverse movement during stropping. For this purpose the blade holder with its pivot shaft 4 are axially movable between the forks 2 of the razor, and the shaft 4 projects through openings in the side walls of the box to engage the parts 25 of the lid which are then transversely inclined. The pinion 17 on the blade pivot shaft is then either feathered to its shaft or the roller pinion 8 is sufficiently wide to maintain mesh.

[Also in Group XXII] A cage for a roller bearing comprises a cylindrical sleeve in -which are punched -slots or windows 2 to receive -rollers 1. Said windows have varying widths over their length such that their ends 5 are narrower in width than the rollers, with adjacent portions 6 wider than the rollers followed by a central portion 7of reduced width Bar portions 9 and 10 are integral with end rings 3 and are offset but parallel and associate with the window portions 5 and 7. Oblique or radially extending portions 11 connect the bar portions 9 and 10 and the rollers are retained therebetween in the windows 2, on the inside and outside of the pitch circle line 8, respectively. The spacing of the bar portions situated outside the pitch circle is greater than the bar portions on the inside of the pitch circle and hence the rollers bear only on guide surface 14. The radial freedom of the cage between inner and outer raceways 15 and 16, respectively, is less than the radial freedom of each two inter-associated guide surfaces 14 relative to the surface 13 of the roller. Other embodiments include a cage arrangement where the guiding is effected on the outer bar portions only with or without a reversed offset portion and where the guiding may be effected by noses located on the centre portion of the bars.
