Filed: 1975-06-16
Abstract: 1506747 Electronic piano WURLITZER CO 16 June 1975 [1 Aug 1974] 25564/75 Heading G5J In an electronic piano, the fundamental frequency and predetermined harmonics corresponding to a key are combined in a predetermined amplitude relationship by a diode matrix (Fig. 2) on playing that key. The relative amplitudes are determined by the resistances of the diodes, which may be in the form of a discrete resistor and a discrete diode. The electronic piano (Fig. 1, not shown) comprises a frequency generator to provide the fundamental frequencies of the third octave above middle C, a divider bank providing lower fundamentals and harmonics, the diode adders, a pulse and sustain circuit shaping the attack, decay and damping of the piano envelope characteristics, output filters and an amplifier.

Title: Flow control valve
IPC: F16K1/52
Filed: 1964-06-22
Abstract: 1,064,868. Valves. SARCO CO. Inc. June 22, 1964 [July 30, 1963], No. 25646/64. Heading F2V. A valve closure member moves relative to its seat 3 on rotation of a valve stem at the upper end of which is a spring clip 17 in a groove 16, said clip limiting the extent of the upward movement of the stem and valve by stopping against an abutment member 18. By rotating the member 18 relative to a bonnet 2, the extent of valve movement can be regulated. Thus, the valve can be closed and reopened by the turning of the stem to any one maximum position preset by rotation of member 18. A pointer 22 co-operates with a graduated scale 23 to give a reading of the percentage of maximum flow obtainable on fully opening the valve. A screw 24 locks the member 18 in the preset position. The closure member either closes the passage of flow, as shown, or is lifted upwards to the fully open position of this passage to seal entry into the chamber containing the valve stem to permit the replacement of the packing. In a modification, the sealing member 4 is separated from a flange 7 by a spring washer to permit a small fluid flow around the stem in the closed position of the valve.

Title: Soap dispenser
IPC: A47K5/12
Filed: 1973-05-31
Abstract: 1409845 Reciprocating pumps; dispensing liquids STEINER CO LAUSANNE SA 31 May 1973 [2 June 1972] 25973/73 Headings F1A and F1R A soap dispenser comprises a plunger pump and means actuating the pump piston-rod which also advances a plunger in a disposable container forming a soap reservoir to pressurize the soap for flowing into the pump. A hand-operated lever 31 is connected to the piston-rod 16 and operates to advance the piston 15 against a spring 18, pressure of soap in a discharge channel 12 causing a spring-biased slide valve 28 to retract and permit delivery of soap. During the piston advance, a resilient sleeve 22 opens inlet 19 to admit the next charge. Piston 15 has a passage 23 and flap valve 24 through which the soap flows during the return stroke. The lever 31 pivots a further lever 44, 45 to raise a rod 39 against a spring 43. The rising rod slides through a plate 49 pivoted to a sliding member 38 on which is mounted a plunger 54. The rod then descends and the plate 49 tilts to jam against it so that the sliding member 38 and plunger 54 move downwards. The plunger is a sliding fit in a disposable container 3 which is initially inverted into the dispenser where a knife 9 cuts into the neck 6 to permit soap to flow into a chamber in communication with the pump inlet. As the plunger 54 descends, the soap is forced towards the pump and a knife edge 57 on the member 38 cuts the container wall to allow passage of the plunger support bracket 53. Levers (58) on the member 38, Fig.2 (not shown), may be pivoted to trip the plate 49, by projections on the casing 61 as the latter is removed, enabling the-plunger to be raised clear of the container with the casing. The rod 39 may be of adjustable length.

Abstract: 231,102. Sharp, R. W. Nov. 1, 1924. Roller mills.-The entrance end of the carrier or shoot disposed between the macerating or expressing rollers of adjacent sugar-cane mills arranged in series is provided with an adjustable upwardly-inclined feed-plate 13 and an adjustable upper plate 14 carrying a scraper 15 to engage the upper roller 10 of the mill. An adjustable bottom-feed plate 16 and an adjustable lower plate 17 with a scraper 18 to engage the lower adjacent roller 11 of the mill may be provided. The plate 14 is supported from a transverse beam 18<1> which is swivelled in the side frames of the mill, and the upper portion 19 of the scraper toe 15 lies over the lower edge of the plate 14, a steel liner 20 being interposed between the parts 14, 19. The toe 15 is recessed to receive the liner 20 and lower edge of the plate 14 and the forward wall 23 of the recess is spaced from the lower edge of the plate 14 and is concavely recessed to receive the upwardly-curved front edge 24 of the plate 13 which bears against the rounded edge 25 of the plate 14. The toe 15 is secured to the plate 14 by bolts 21. A series of segmental rails 26 secured to the upper surface of the plate 13 adjacent its upper edge extend upwardly through slots 27 in the plate 14 and are engaged by a latch-plate 28 carried by the plate 14. The plate 28 is held by a series of screws 29 extending through the upper end portions of the elongated slots 27. Pins 43 prevent the racks 26 from escaping downwardly through the slots 27. On loosening the screws 29, the screws and plate 28 can be slid outwardly from the racks 26 and then the plate 14 can be adjusted to bring the toe 15 properly against the roller 10 and the plate 13 can be lifted to adjust the passage through the shoot 12. The bottom feed-plate 16 may be stationary, but is preferably adjustable by means similar to those of the plate 13, and is connected to the plate 17 and scraper 18 by means similar to those of the plate 14 and scraper 15.

Abstract: 1,144,582. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. 10 June, 1966 [10 June, 1965; 20 Aug., 19651, No. 26087/66. Heading H1K. A PN junction semi-conductor element in a housing consisting of metal cover-plates spaced apart by an insulator is held between a pair of electrically conductive cooling plates which have centrally disposed seatings and are supported at at least two peripheral regions by insulating distance-pieces. As shown in Fig. 1, a series of devices is arranged in a stack. In this case the plates are resilient and centrally dished to form a seating for the device which may be inserted by pushing the plates apart. The distance pieces 13 &c. which each have three protrusions on one face and mating blind bores on the other interlock through corresponding holes formed in the plates and are threaded on rods SP with the cooling plates which have tabs to facilitate electrical connection. In an alternative arrangement two cooling plates connected at their centres by a cooling block and spaced by distance-pieces at the periphery are disposed on each side of each device. The devices may be silicon rectifiers in sealed housings consisting of a metallized ceramic ring with silver end-plates, Fig. 5 (not shown). Each rectifier consists of a silicon wafer alloyed to silver plates, on one face with aluminium and on the other with gold-antimony, the silver plates in turn being attached to molybdenum blocks. Electrical and thermal contact to the housing walls may be improved by disposing ductile inserts between them and the cooling plates.

Abstract: 679,968. Securing sleeves on shafts. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 9, 1950 [Oct. 11, 1949], No. 26117/49. Class 80 (ii). In a coupling between a shaft 1 and an external annular member 2 in which torque is transmitted by splines 3 and the members 1, 2 are located concentrically with respect to each other by co-operating lands 5, 6 at each end of the coupling, the member 2 is formed with an annular recess 8 in which is mounted a ring 10 the internal diameter of which corresponds with the diameter of the land 6. The ring 10 is retained in the outer member by a shrinking operation and by a threaded ring 11. Axial location of the member 2 is achieved by clamping the ring 10 against a shoulder 7 by means of a ring 12. The construction reduces the length over which the effect of differential expansion is operative and enables the splines 3 to be machined by a broaching operation instead of by slotting. The shaft 1 may be of austenitic material and may be the rotor shaft of a gas turbine. The member 2 may be of ferritic material. According to the Provisional Specification the ring 10 may be integral with the member 2.
