Abstract: 945,821. Dish washers. CONSTRUCTAWERKE G.m.b.H. April 11, 1961 [April 14, 1960], No. 12990/61. Heading A4F. A dish washing machine includes a built-in chemically working base exchange water softener 13 arranged in the water supply to the washing chamber 3 and which may be regenerated by supplying chemical regenerating agents through a supply opening e.g. funnel 27, in the machine. Cold water is fed to the softener through an inlet 10 and a pipe 11 provided with an electromagnetic valve 12 and thence to a preparation chamber 15 provided with heating means 16 and a washing agent feed pipe 17. The softener 13 may be by-passed by feeding water from the inlet 12 via a branch conduit 19 to the feed pipe 17 for washing agent. Cleaning liquid is circulated after extraction from the preparation chamber 15 by a pump 7, and passes via a pipe 8 and sprayers 9 through the washing chamber 3 and thence through a filter screen 5 into a liquid chamber 4 and back to the pump 7. A discharge pump 22 and outlet pipe 22 for used washing liquid and a discharge pipe 29 for the softener 13 are provided. The softener 13 is regenerated with sodium chloride solution via the funnel 27 and pipe 25. Also provided are a washing cycle counter mechanism and visual or acoustic means of indicating that the capacity of the softener has been exhausted and said means may be arranged to actuate the valve 12 to close.

Title: Improvements in means for transmission of power by belt or chain, and incorporating annular floating toothed gearing
IPC: F16H7/06
Filed: 1943-08-12
Abstract: 574,399. Chain and belt gearing; toothed gearing. NORTHERN PATENT DEVELOPMENTS, Ltd., and BARTLETT, B. G. W. Aug. 12, 1943, No. 13069. [Class 80 (i)] [Also in Group XXXI] In belt or chain drives incorporating annular floating toothed gearing, means are provided for adjusting and tightening the driving and return runs of the chain or belt. As applied to the drive of a velocipede, a driving sprocket 11 is connected by a chain or belt 17 to an annular floating ring gear 14, internal teeth 15 of which mesh with a driven pinion 12 mounted on the rear wheel hub on the spindle 13. The internal teeth 15 and the teeth of pinion 12 are shrouded to their pitch circles. A bracket 18 is mounted on the spindle 13 and secured by a clip 19 to the back-stay 20. An idler roller 21 is adjustably mounted in a slot 23 of the bracket and is adapted to engage the shrouds 35 of the internal gear 15 when the mechanism is at rest. When the gearing is being assembled with the chain slack, the roller 21 is moved rearwards to depress the ring 14 and tighten the runs 25, 26 of the chain, the length of which is such that when adjusted, the point of contact 27 between the internal gear 15 and the pinion 12 lies above a line between the axis 13 and the axis 28 of the sprocket 11 and, further, the line 27-13 makes an angle of approximately 130 degrees with the line 13-28. When a drive is being transmitted, the ring 14 is moved slightly downwards and out of contact with the roller 21. On back-pedalling, the ring is raised into contact with the roller 21 which assists braking and limits the upward movement of the ring. The surface of the roller 21 may be of non-metallic material. The gearing may be enclosed in a casing. Specification 415,085 is referred to.

Filed: 1925-05-19
Abstract: 254,064. Steere, G. R., and Eberlein, J. B. May 19, 1925. Producer plant.-In a watergas plant adapted for back running, a swing valve is arranged between ports leading from the producer and the superheater respectively to the wash-box, and the means which actuate the swing valve also control a steam valve. The producer 5 is connected by pipes 17, 18 with a valve casing arranged above the wash-box 8, and the superheater is connected with the casing by a pipe 14. The openings of the pipes 14, 17 are closed in turn by the swing valve which comprises a pair of plates 23 joined centrally by a web having a spherical part 24 through which passes a bolt 22 and secures the valve to a yoke 20; the bolt bears against the central part only of the aperture so as to permit a limited universal movement. The yoke is secured to a shaft 19 mounted within the casing and connected by a lever 28 with a shaft 29 reciprocated by a hydraulic cylinder 31. A lever 36 at the end of the shaft 29 controls a valve 35 to admit steam to either of the pipes 14 and 17. The valve 23 is kept clean by a water spray 37 which supplies the wash-box.

Abstract: 433,232. Liquefying gases. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and KEELAN, R. E., c/o General Electric Co., 71, Waterloo Street, Glasgow. May 2, 1934, No. 13254. [Class 8 (ii)] [See also Group XXXV] In obtaining gases from the atmosphere, an engine is used in which compressed gases are expanded, the power of the engine driving an induction generator which is electrically connected with alternating current power supply. The generator is an ordinary induction motor 1 driven above its synchronous speed and supplied from alternating current bus-bars 2, the leads 3 from the slip rings 4 of the rotor windings being connected to rotor regulating resistances in order to vary the load on the engine. The resistances may be varied automatically in accordance, e.g. with the pressure of the engine exhaust. Alternatively the relative speeds of engine and generator may be varied by use of a cone pulley drive, the induction generator being of the squirrel cage type.

Title: The making of impregnated porous metal articles
IPC: B22F3/26
Filed: 1953-05-14
Abstract: 727,449. Powder metallurgy. GENERAL MOTORS CORPORATION. May 14, 1953 [May 22, 1952; May 22, 1952], No. 13462/53. Classes 83 (1) and 83 (4). Casting composite articles.-A method of making impregnated porous metal articles comprises heating a shaped compacted porous mass of metal together but out of contact with an impregnating metal to a temperature and for a time sufficient to sinter the mass and melt the impregnating metal and, after sintering is complete permitting the melt to impregnate the porous mass while at substantially the sintering temperature and finally cooling the article. The porous mass may be of ferrous or cuprous material and the infiltrant predominantly of lead or the porous mass may be of ferrous and the infiltrant of cuprous metal. Fig. 1 shows a crucible 20 in position on a porous compact 22, the crucible containing impregnating material 30 to be melted. The compact and crucible are passed through a furnace in which sintering of the compact and melting of the infiltrant are effected. Valve 26 is then rocked, e.g. by rod 28 striking a projection on the furnace, permitting the infiltrant to flow through ducts 27 on to the compact. Infiltration of an iron compact, formed by briquetting iron powder at a pressure of about 45,000 lbs./square inch, with copper is carried out in a non-oxidizing or reducing atmosphere at a temperature of 1900- 2050‹ F., the time of travel through the furnace, before the molten copper is allowed to contact the compact, being about 30 minutes. The copper should contain dissolved iron to prevent its dissolving action on the compact. This iron may be added to the crucible as powder or as a porous iron ring or lining or copper which has previously been melted with iron may be used. In a further example a copper-tin mixture (90 per cent copper-10 per cent tin), is briquetted at about 35,000 lbs./ square inch, and lead is used as infiltrant, the temperature in the melting and sintering zone of the furnace being 1450‹ to 1650‹ F. maintained for 10-30 minutes before contacting the compact and infiltrant.

Abstract: 173,531. Angus, A. R. July 10, 1920. Drawings to Specification. Electrical systems, non-automatic.-At parts of a road where tracks join, the track rails are divided by insulation joints, one of which is placed in each portion of rail between the opposite rails of the other track and relays are arranged in shunt to the insulation joints and also across the rails of certain sections and connections are made to hand-operated switches, one for each road, by means of which the signalman first makes a circuit to the track rails and to the relays; if all sections are in order and clear the points are then operated and the hand lever moved to a second position to complete a further testing circuit through contacts of these relays and the pointsdetectors. The lever is then moved to a third position to complete in addition a circuit over contacts at the other hand levers, which must be normal, to a lock on the signal lever which if all is clear is released for completion of its operation to a position in which the signal circuit is completed. The signals may be track-side signals or may be on the train and in this case may be controlled by current collected from the rails or from track ramps. Currents of different polarity or frequency may be used for different directions of travel.
