Title: Washing machines utilising softened water
IPC: A47L15/42
Filed: 1968-01-18
Abstract: 1,215,482. Washing machines. CANDY S.p.A. 18 Jan., 1968 [18 Jan., 1967], No. 2795/ 68. Heading D1A. [Also in Division A4] Washing machines utilising a demineralisation stop have at least two valves which limit the flow of softened water into the washing tank to that part of the cycle when operations are being carried out above 60‹C. The cycle may be timed so that regeneration of the resin takes place by use of a third valve during the final drying phase of the cycle. The flows of water may be controlled to ensure suitable time for dosing with detergent, demineralisation and regeneration. A cycle is described with prewash at ambient temperature, washing at 75 to 80‹C, two cold rinses, a hot sterilisation rinse at 75 to 80‹C and drying. During drying regeneration of the resin takes place.

Title: Improvements in detachable mountings for lighting fittings
IPC: F21V21/112
Filed: 1946-01-29
Abstract: 623,992. Supporting electric lamps. FENN, J. J., and BENJAMIN ELECTRIC, Ltd. Jan. 29, 1946, No. 2868. [Classes 75(ii), 75(iii) and 75(iv)] A lighting fitting for tubular lamps is supported by a slot therein being engaged by means inserted through the slot and then turned to lie across the slot and clamped therein, such support means being adjustable along the slot and therefore being adapted to connect with irregularly spaced electric supply conduit. The supporting and clamping means Figs. 3 and 4 comprises two plates 13, 14 connected for rotation together by two rivets 18 on which the lower plate 14 can slide to provide a groove between the plates which groove receives the edges of the slot of the lighting fitting. The top plate 13 is of a greater dimension than the slot but the bottom plate 14 is turned down at two sides 14a to give a width there which is less than that of the slot so that this lower plate can enter the slot and on being turned so that its longer dimension lies across the slot the lighting fitting is supported thereby, the plates 12, 14 being secured on a supply conduit piece 15 between two nuts 16, 17 the upper nut 17 having a fingered head for hand tightening to clamp the plates 13, 14 in their adjusted position along the slot. Depending lugs 13b, Fig. 4, on the top plate act as stops for the two limit positions of the lower plate 14 by butting against the edges of the slot. The lighting fitting comprises two sheet metal portions 10a, 10b, Fig. 3, joined by a channel member 12 having edges engaged by the doubled over edges of the portions 10a, 10b, these edges providing the slot of the lighting fitting. A reflector 11, Fig. 1, may be secured by catch members 30 each provided with a finger grip 31a and having a grooved stem adapted to be engaged by inwardly projecting arms of a U-shaped spring 32 on a bracket 28 secured to the base of the channel member 12, the reflector being released by rotation of the grips 31a to cause the springs 32 to ride out of their respective grooves. The electric cable from the conduit passes to a plug and socket 23, 24 mounted in the channel portion 12. By withdrawing the plug 23 and turning the support plates 13, 14 the whole lighting fitting may be readily removed. Chain suspension may be provided by hook inserted in the conduit piece 15.

Title: Improvements relating to train control and fog signalling apparatus
IPC: B61L3/02
Filed: 1923-01-31
Abstract: 213,055. Kerr, A. Jan. 31, 1923. Track apparatus actuating signals on trains and for stopping trains.-The brakes and whistles operated by air entering or leaving the brake system are controlled by a venting valve which is opened by the simultaneous opening of a valve tripped by engagement of a traincontact with a fixed track ramp and an electromagnetically controlled valve, the electromagnet of which is energized by current from the same ramp, to hold the valve closed when a clear signal is to be given. The track ramps are set to move the train carried contacts 7, 8 to right or left according to direction of travel, the displacements being greater at home signals than at distant signals. Two contacts are fitted to provide for the locomotive running tender first. At a distant signal the arm 12 is deflected only sufficiently for a cam on the spindle 13 to open the valve 20, the valve 24 being unaffected. Air then passes through the pipe 20<c> to the cylinder 21 and the piston 21a lifts the valve 21b to admit air from the line clear whistle and port 21<c> to the brakepipe connection 5<d>. If the signal is clear, the magnet 6 is energized by current collected by the brush 10 and the contacts 7, 8 from the track ramp and the valve 5 is kept closed. If the signal is at danger, the air from cylinder 21 raises the valves 5, 5<b> and a danger whistle is sounded and the brakes are partially applied. At a stop signal, the valve 24 is also opened by the cam on the spindle 13 and air enters conduit 24<b> by way of the port 20<k>, and, if the signal is at danger, passes through an annular channel 5f to the cylinder 23, the piston of which operates a full bore vent valve 23<b>, which is kept open by a spring detent 23<c> until reset by hand. The magnet 6 may be in the circuit from the brush 10 and contacts 7, 8, or, in order to permit the use of very short ramps, a self-holding relay 32 may be provided. The coil 32 is in series with the brush 10 and the energization of the relay establishes a holding circuit which includes the core 32a and the armature 35 and a contact 45 which is opened on restoration of the piston 21 to normal. The rate of movement of the piston is predetermined by the size of the ports 21<g> in the piston. The trip-operated valves are reset by a spring 20<f>, the operation being retarded by the escape of air, which entered through a non-return valve 20<g>, through a small perforation in a flexible diaphragm 20<d>. When a train runs in reverse direction along the track over a ramp which is intended to apply only to normal running, the arm 12 is moved so that the cam on spindle 13 operates another valve 80 which may be utilized to give a special signal. According to the Provisional Specification the valves used may be similar to the valves described in Specification 121,327.

Abstract: 1467795 Purifying sulphuric acid WACKERCHEMIE GmbH 27 Jan 1976 [29 Jan 1975] 03076/76 Heading C1A Sulphuric acid contaminated by methyl sulphuric acid is purified by diluting the contaminated acid with 10-25% by weight with liquid water based on the content of H 2 SO 4  so that diluted acid has a strength not less than 60% weight, subsequently passing steam at 95-150‹ C. through the acid such that the temperature thereof rises to 170-180‹ C. and distilling of the methanol so formed. The amount of water added is advantageously 15-20%. The contaminated acid is preferably at 90-110‹ C. immediately prior to the introduction of steam. The process is preferably carried out at atmospheric pressure, but higher or lower pressures may be used. The process may be continuous, semicontinuous or batch.

Title: Improvements in and relating to knitting machines and patterning mechanism therefor
IPC: D04B15/66
Filed: 1945-02-07
Abstract: 601,677. Knitting-machines. BENTLEY ENGINEERING CO.,Ltd., and PEBERDY, R. Feb. 7, 1945, No. 3088. [Class 74(ii)] Patterning mechanism, particularly for a circular machine, comprises a drum, chain or like cyclic selecting device and a feeler engaging pins, studs or the like thereon, is provided with a collapsable joint in the operating connection between the feeler and the yarn guides or other knitting parts to be operated selectively, and means for collapsing and erecting the joint. As applied to a machine employing pattern chains 1, 2, feelers 22, 24, adapted to engage studs on the chains, are connected to yarn guides, or other parts to be controlled by levers 28, 30, 25, 27. When the studs on the pattern chain are to be operative upon the yarn guides, the ends of the levers 28, 30, rest on the curved faces of the cams 20, 33, mounted on a rocking shaft 11 upon which the feelers 22, 24, are loosely mounted. The shaft 11 is rocked by means of the main pattern drum 35 to move the cams, 20, 33, from beneath the ends of the levers 28, 30, so that although the feelers 22, 24 may be raised by studs upon the pattern chain 1, 2, the links 25, 27, are not raised far enough to operate the thread guides. The driving pawl 5 of the pattern chain may be disabled, e.g. during the knitting of a stocking heel, by a rocking movement imparted to the lever 10 by a lever 23 and the pattern drum 35. Rotation of the pattern chains is also discontinued, on completion of the article being knitted, by an axial movement of the lever 10, under control of the drum 35, so as to bring it into line with the pattern chain 1 which carries a stud for rocking the lever 10 and disabling the pawl 5.
