Title: Improvements in the lubrication of journal bearings
IPC: B61F17/10
Filed: 1930-09-09
Abstract: 363,355. Centrifugal-action lubricating. IVITSKY, V., 11, Queen Victoria Street, London. Sept. 9, 1930, No. 26935. [Class 12 (iii).] Conical partitions 11, 12, Fig. 1, secured within the-hollow hub 1 of a railway-vehicle-wheel rotating on rings 9 secured to a stationary axle 2 form outer and inner oil chambers 16, -19 within the hub, whereby oil in the inner chamber 19 passes centrifugally from the large ends of the partition into the adjacent bearings 8. From the outer ends of the latter the oil passes centrifugally through passages 14 and through filter cloths 18 arranged on perforated plates 17 into the outer chamber 16. Oil gravitates from the latter into the chamber 19 through the gap between the small ends of the partitions when the wheel'is stationary, or may be caused to circulate continuously by means of a disc 20 or scoops secured to the axle. Alternatively, the two partitions may be replaced by a single partition 23, Fig.,3, of double conical form provided with holes 30 in its central neck part, scoops 22 directed in opposite directions being secured to the partition so as to cause oil to flow from the chamber 16 to the chamber 19 in either direction of rotation. Instead of the filtering device 17, 18, an undercut groove 26, Fig. 3, may be formed in the deepest part of the hub, the groove being closed by a ring 24 with nozzle-shaped openings 25, whereby impurities are retained centrifugally in the groove. The Provisional Specification describes also the application of rotating partitions for the lubrication of the bearings of rotating axles.

Filed: 1973-06-06
Abstract: 1424733 Rotary-piston fluid-machines ROLLS-ROYCE MOTORS Ltd 24 May 1974 [6 June 1973] 26961/73 Addition to 1182097 Heading F1F The main invention is improved or modified by the addition of a slot or slots 12 on the trailing side of each apex seal 3 to give fluid in chamber B access to the underside of the seal when the latter is in the attitude shown. The seal may have a recess at 18, Fig. 4, so as to prevent communication between the chamber B and the underside of the seal when the latter is tilted towards said chamber. Alternatively, the seal may be shaped as shown in Fig. 5 to increase the pressure loading of the seal towards the housing.

As shown in Fig. 3, the front side 1 of the shell 2 is slit to form the flap 5 which has fixed to its inner face the matches 8 and which is connected by a flexible strip 10 with the bottom of the drawer 3 so that the flap is also automatically closed when the drawer is pushed into the shell ; the matches may be held in a pocket fixed to the inner face of the flap and a striking surface 9 is fixed to the inner face of the closing flap 7 of the drawer or in any other suitable position. The flap may have a tail which is engaged by the bottom of the drawer to close the flap and one or more projections may be arranged on the drawer to engage the tail to swing the hinged flap to the open position or the edge of the bottom flap of the drawer may be so arranged. In another form a resilient projecting member arranged on the hinged flap is compressed between such flap and the bottom flap of the drawer when the hinged flap is held closed by the closing flap of the drawer so that, when such closing flap is released by withdrawal of the drawer, the hinged flap is automatically opened by the resilient member ; the resilient member may be arranged on the bottom flap of the drawer and may be positioned so that it engages over an edge of the bottom flap of the drawer or of the hinged flap respectively.

Title: Fluorinated aromatic amino acids and amide derivatives thereof
Inventor: BELF LEON JERZY
Filed: 1960-08-04
Abstract: The invention comprises p-amino-tetrafluoro-benzoic acid NH2.C6F4.COOH, its amide and its N-diethyl amide; diamino-trifluorobenzoic acid and the corresponding amide and N-diethyl amide.  The new compounds of the formula NH2.C6F4COX, where X is -OH, -NH2 or -N(C2H5)2, are made by reacting a compound of the formula C6F5COX with sodamide in liquid ammonia. The amides may also be made by reacting C6H5COX with alcoholic ammonia at elevated temperature and pressure, e.g. in an autoclave.  Diaminosubstituted compounds may be obtained by this method if heating continues for long enough.  The p-amino-tetrafluorobenzoic acid or di-amino-trifluorobenzoic acid may be obtained from the corresponding unsubstituted amide by alkaline hydrolysis, e.g. with 20% NaOH solution, followed by acidification.  Detailed examples are given.

Abstract: 1,183,558. Tunnels. PHILIPP HOLZMANN A.G. 7 June, 1968 [10 June, 1967], No. 27118/68. Heading E1F. A tunnel ring is composed of a plurality of steel channel members containing concrete arranged so that the steel members and not the concrete take-up hoop stresses in the ring thus allowing the steel members to deform elastically. Within each channel the concrete may be arranged in separate sections separated by bitumen. Alternatively slots filled with bitumen may be arranged in that face of the concrete which is subjected to compressive forces. The ring may be composed of four arcuate channel members each of which may have a central T-sectioned web. A lubricant may be applied to the channel members to prevent adherence of the concrete and to prevent corrosion of the members. An inner layer of concrete may be applied to the ring after deformation, if say, of the channel members.

Title: Rotary wheel printing apparatus
IPC: B41J9/48
Filed: 1975-06-30
Abstract: 1502956 Printers QUME CORP 30 June 1975 [1 July 1974] 27598/75 Heading G4H In a printer having a rotary print wheel movable along a print line, hammer impression intensity is controlled by intensity characters from a store. As disclosed, a character to be printed is supplied by a computer and used to address two portions of a ROM in turn to obtain the twos-complement of the character position on the print wheel, then an intensity character. The former is compared with a print wheel position counter (driven by pulses derived by logic from the outputs of sensors of a displacement encoding disc linked to the print wheel), the difference signal from the comparison being twos-complemented or not (according to the shortest-route direction, determined by comparison of the initial difference signal with a constant in an adder), then decoded to select a voltage specifying the optimum print wheel velocity (in dependence also on the direction required for shortest-route). The velocity voltage is combined with an actual velocity signal to control a motor driving the print wheel, the actual velocity signal being obtained by a differentiator responsive to the logic referred to (responsive to the displacement disc). When the difference signal referred to is zero, the above (rate) mode ends, the print wheel stops, and the print wheel motor is controlled in a position mode by an output of the logic acting as a position error signal. The hammer is actuated by a pulse from a one-shot, the duration of which is controlled via a D/A converter by the intensity character. The carriage (supporting the print wheel) is moved to the next print position in the line, the distance being specified by the computer which loads a counter which is then driven as the carriage moves, movement being stopped at counter zero. Servo control of the movement is otherwise similar to the above-described control of the print wheel.
