Title: Heater for use in the manufacture of plastics filaments
IPC: D01D5/084
Filed: 1972-03-30
Abstract: 1391471 Heater for spun filaments HOECHST AG 30 March 1972 [30 March 1971] 15178/72 Heading B5B  A heater for use in the manufacture of spun plastics filaments comprises two portions 1 and 2 each having the shape of a truncated cone, attached to each other at their larger ends. Lower part 2 is heated while the inside wall of of the upper part 1 reflects the heat emitted by the lower part. The lower opening 3 of the heater is protected by an annular screen 4 preventing air blown on to the filaments after they have left the heater passing upwardly through the heater and entering the space below the spinneret; suitably the diameter d, of the opening in the screen is only 5 to 30 mm. larger than the diameter d of the bundle of filaments. The length L of the heater is from 1À0 to 2.5 times the diamter d 4  of the opening in the upper part of the heater, and the cross-sectional area at the largest diameter d 3  of the heater is preferably at least twice the cross-sectional area of the bundle of filaments. The biconical shape of the heater allows concentric thermal radiation and ensures that only a minor part of the thermal radiation reaches the spinneret, the major part being reflected by the conical reflector into the space below the spinneret. To facilitate such reflection the reflector 1 is provided with a highly polished surface or coated with a reflecting foil. The heating elements of radiator 2 preferably consist of ceramic plates with inserted heating spirals. The use of the heater enables filaments of a very low degree of pre-orientation to be obtained, so that higher draw ratios can be used in stretching, and filaments of higher strength produced. Alternatively the throughput of molten material can be increased, since the higher pre-orientation resulting from a higher draw-off speed can be compensated for in the heater. The meltspinning of polyesters is exemplified.

Abstract: 505,867. Automatic volume control. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 23,1938, No. 15347. Convention date, May 25, 1937. [Class 40 (v)] Relates to delayed A.V.C. circuits in which the A.V.C. source is shunted by a conducting rectifier until incoming signals exceed a predetermined amplitude and render the rectifier non-conducting. As shown the A.V.C. rectifier 6 of a radio receiver feeds the A.V.C. line 14 through resistance 10, the delay diode 12 being connected, with the cathode resistance of valve 7 containing the diodes 6, 12, between the line 14 and earth. In the absence of signals the anode of diode 12 is positively biassed through resistance 13 and this positive bias is fed to the controlled valve 2 over the line 14 to produce muting. When signals exceed a predetermined amplitude the diode 12 becomes nonconducting when its anode becomes negative by virtue of its connection to the diode 6 and A.V.C. ensues. The signal detector diode 18 is in the output valve 16, the triode 7 being the first L.F. amplifier.

Filed: 1940-10-18
Abstract: 544,680. Centrifugal machines. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 18, 1940, No. 15433. Convention date, Nov. 21, 1939. [Class 23] [Also in Groups VIII and XXIV] A washing and drying machine having a perforated basket mounted on a horizontal or inclined spindle to rotate within a tub resiliently supported within a casing has a multi-speed transmission carried by, and adjacent to one end of the tube whereby the spindle and basket can be driven at a low speed for washing and a high speed for centrifuging from a motor carried by the tub and driving the speed gear. The speed gear is mounted in a housing 32 fixed to the base 12 of the tub and comprises a shaft 45 driven from the motor 31 by a belt 34 and a pulley 33 fixed to the shaft which by splines 46 thereon drives a planet wheel 54 carried by a hub 51 secured to a sleeve 48. The planet wheel gears with an internally toothed wheel 55 having also a ring of ratchet teeth 96 and mounted by its sleeve 72 on the sleeve 67 of a clutch element 71 adapted to engage or release a corresponding clutch element 66 on the hub 51. The clutch elements are moved into and held in engagement when a spring-pressed brake 75 engages a sleeve 73 having pins 83 engaging helical slots 84 in the sleeve 72 whereupon the hub 51 and outer gear rotate together and a high speed drive is transmitted from the shaft 45 through the pin 69, the clutch 66, 71, the pin 52, a sleeve 48 and a pin 59 to a hub 56 secured to the basket. A slow speed drive, for washing, is imparted when the brake 75 is withdrawn by an electromagnet whereupon pins 83 move in the helical slots 84 in the sleeve 72 by the action of biassing springs 85 connected to the sleeve 73 and the orbit gear 55 and allow the clutch member 65 to disengage the hub 51 carrying the planet wheel, the drive being then transmitted from the shaft 45 through the planet gear 54 and the hub 51 to the sleeve 48, the orbit gear at this time being held by a pawl 99 engaging under the action of a spring 97, the ratchet teeth 96 on the orbit gear. The motor 31 is carried by baskets 37, 41 from the tub and housing 32 and drives a pump 28 for drawing off water when a valve 29 is opened. Liquid is supplied through a pipe 26 and nozzle 25. The tub is suspended within the casing 101 by springs 106, 108, and the tub and casing are fitted with covers 21 and 105 the central part 22 of the cover 21 being transparent. During washing, at low speed, the clothes are lifed by the vanes 17 and fall over the inset bottom 16 of the basket into the bottom corner, and during centrifuging, at high speed, the clothes are flung against the periphery.

Abstract: 942,638. Filters. ALLIS - CHALMERS MANUFACTURING CO. April 24, 1962 [April 26, 1961], No. 15565/62. Heading B1D. When a hoist drum 43 is rotated clockwise, cables 46, 47 are both wound on to it so that a rake mechanism travels upwards along a bar screen 12, and vice versa. To rotate the rake teeth 29 into operative position, a hoist drum 44 is rotated anticlockwise, whereby cable 47 is unwound therefrom, lowering pulley block 39 a little, and cable 46 is wound thereon, raising pulley block 38. These movements result in the rotation anticlockwise, about a pivot 33 on the mechanism, of a lever 34 ; this lever is linked (at 36 and 37) to the rotatable shaft 31 on which the teeth are mounted. Successive positions of the shaft and teeth during this operation are shown in dotted lines at the foot of Fig. 1. In the operative position of the teeth they form with a closed back 26 and side plates 27 a box in which debris is collected ; the debris is discharged into a removable receptacle 24 by retracting the teeth when the mechanism is located over a gap between guides 48 forming a continuation of the bars 12.

Title: Improvements relating to metering in automatic telephone systems
Inventor: PHILPOTT WILLIAM HARRY
IPC: H04M15/10
Filed: 1953-06-05
Abstract: 733,023. Automatic exchange systems. SIEMENS BROS. & CO., Ltd. June 4, 1954 [June 5, 1953], No. 15580/53. Class 40 (4). In a system in which a calling party's meter is operated periodically under the control of timing equipment associated with an outgoing repeater, a warning tone being given towards the end of each metering period, the transmission of the tone from each tandem exchange in a connection is prevented by a test made over the private wire to determine whether a meter is connected thereto or not. Metering is initiated by cam-controlled relay DA dependent on the operation of D when the called party replies, and a relay operated after DA puts DC (not shown) under the control of selected cam contacts to effect the initial metering operation and starts the timing equipment TE. In Fig. 1, DA is dependent also on a slowrelease relay X which pulls up after the first digit repeated at the repeater OR and locks under the control of DC. The latter relay at each operation connects metering battery to the P wire through a low-resistance relay P, which at the originating exchange as shown energizes in series with the meter SM and holds X. At a tandem exchange, however, where P is inoperative, X is unlocked by DC, disconnects DA and restores the timing equipment. In Fig. 2, a grounded relay IC controlling DA is connected as shown to the P wire, rectifier MC preventing its operation in series with switching relays H. At a tandem exchange the incoming selector IS has its P wire connected as in Fig. 2A, so that at the first operation of DC, relays P, PR pull up and then release in turn, connecting battery momentarily to the P wire to energize IC with the same effect as that produced by the release of X in Fig. 1. In modifications of this arrangement, Figs. 3, 3A, 4, 4A (not shown), IC is a differential relay in series with line relay A of the repeater OR and relay P when operated at an incoming selector IS grounds one of the talking wires. Call office lines are connected to special first selectors provided with call timing devices. In the embodiment of Fig. 1, a discontinuous P wire within such first selectors has the same effect as an intervening junction. In the other embodiments, the P wires of the special first selectors would be connected in the same way as those of incoming selectors.

Abstract: 734,593. Rotary grinding machines. CHINA, F. J. E. Sept. 10, 1953 [June 20, 1952], No. 15637/52. Class 59. A rotary grinding machine comprises two grinding members US, LS of which at least one (US) is capable of movement away from the other in the direction of the axis of rotation and is held in balanced position by adjustable pneumatic means which provide uniform pressure circumferentially over the grinding surfaces. Flat, curved or coned (single or multiple) co-operating grinding surfaces may be provided of which one may be non-rotatable or rotated in opposite direction to the other; in the case of flat surfaces they need not be coaxial. As illustrated, US does not rotate and is supported in a housing TBH which is guided on bolts BB carrying a bridge B. A rubber bag BL, BT is positioned at each face of the housing TBH and inflated to apply the desired pressure between the grinding members. Soft rubber discs RP act between the bags and the housing TBH and a disc of soft or expanded rubber may replace the bag BL ; alternatively, the lower bag may be replaced by a ring of compression springs. A shield SS is attached to the housing TBH to prevent aeration of the material being ground or emulsified, the final product, which may be finely dispersed in water or oil, leaving the machine through the gap between the shield SS and the grinding members after being pressure- or gravity-fed centrally, at E. The grinding members, which may be formed of stone, metal, carborundum or " Alundum " (Registered Trade Mark), and faced with diamond if required, can be trued by running them in contact with each other with water flowing between. Parts of the machine may be water-cooled, and the bags may have the same axial cross-sectional area. The Provisional Specification illustrates also a construction wherein bags of the same diameter are used and may be inflated by a liquid or gas.
