Title: Apparatus for filling containers
IPC: G01G13/24
Filed: 1974-05-07
Abstract: 1467062 Hoppers PNEUMATIC SCALE CORP 7 May 1974 20138/74 Heading B8S [Also in Division G1] A machine for filling containers C comprises a weighing hopper 14, a hopper 10 for supplying material to the weighing hopper, a closure member 38 for cutting off the flow of material between the hoppers, and an arrangement whereby the closure member 38 moves to the cutting off position when the material in the weighing hopper has attained both a predetermined weight and a predetermined volume. Weighing hopper 14 is carried by a weighing device 16 having a pneumatic nozzle 70 obturated by a member 72 such that when the predetermined weight is reached, a valve V closes and cuts off air pressure to a motor M1. When the material reaches a predetermined level in hopper 14, this is detected by means of a light source 104 and a photo-cell 106, the light source being directed towards the photo-cell across the weighing hopper either directly (Fig. 5, not shown) or indirectly via a reflector (Fig. 4, not shown). When the material in hopper 14 interrupts the beam from the light source, a relay and a solenoid valve operate to cut off the supply of air to a second motor M2. Closure member 38 is mounted on arms 40 pivoted about a shaft 42. A latching hook 66 is mounted on the closure member 38 and is engaged by a roller 88 on an arm 86 to hold the closure member in the open position against the bias of a spring 44. Arm 86 is fixed to shaft 82 to which is also fixed an arm 90. A spring 100 biases the arm 90 and hence shaft 82 and arm 86 in an anticlockwise direction. Rotation of arms 86, 90 and shaft 82 is prevented by motors M1, M2 until the predetermined weight and volume has been achieved and the air supplies to the motors are cut off, whereupon the rotation occurs, latch hook 66 is released, and the closure member moves to cut off the feed of material. The filling and discharge of the weighing hopper are controlled by cams 60, 128 driven by a motor M.K. When the cam portion 64 of cam 60 engages a roller 58, a linkage consisting of bell crank 52, rod 58, lever 46, shaft 42 and lever 43 acts on the closure member 38 to move it to its open position where it is latched by hook 66 and roller 88. At the end of the weighing cycle, cam portion 130 on cam 128 acts on a roller on a lever 124 to open the bottom cover 104.1 of the weighing hopper against the bias of a spring 108.1 via a linkage consisting of lever 124, push rod 122, slotted lever 120, shaft 118 and lever 116. The hopper 10 is supplied with material by means of a conveyer 12 having a vibrator 37.

Patent GB-499965-A (GB)
Title: Improvements in or relating to the production of artificial filaments, yarns and threads
IPC: D01D5/20
Filed: 1937-07-21
Abstract: Artificial filaments having abrupt variations in denier are produced by extruding a spinning solution in the form of filaments, drawing the filaments from the point of extrusion by drawing means which forward the filaments at a constant speed higher than the speed of extrusion, and intermittently making an abrupt change in the length of the path of the filaments between the point of extrusion and the drawing means.  Preferably, the variations in denier are produced by intermittently making an abrupt decrease in the length of the path of the filaments so as to produce intermittently a stoppage in the drawing action at the point of extrusion and between the abrupt decreases lengthening the path at a uniform rate.  The process may be carried out by means of the apparatus shown which comprises a spinning <PICT:0499965/IV/1> cabinet 1, a wick 5 for supplying conditioning agents &c. to the filaments, stationary filament guides 6, movable filament guides 33, and a drawing roll 7.  The guides 33 are mounted on arms 32 fixed to an oscillating shaft 14, the oscillations of which are controlled by an arrangement of levers from a multi-lift cam 15 mounted on a driven shaft 13 to raise slowly and lower abruptly the guides 33.  By the choice of a suitable cam 15 the variations in denier imparted to the filaments may be made of different degree and/or length and by rotating the shaft 13 carrying the cam 15 at varying speeds the variations in denier may be produced at irregular intervals. ash-pots may be provided at suitable points in the apparatus to prevent bumping.  The filaments, if desired after reducing them to staple lengths, may be formed into yarns alone or with threads of natural or other artificial filaments or fibres. They may be woven or knitted or otherwise worked into fabrics alone or in association with yarns of natural or other artificial filaments.  The process is applicable to filaments produced by wet or dry spinning and the initial material may be a cellulose derivative such as cellulose-acetate, viscose, &c.  Reference has been directed by the Comptroller to Specification 321,762, [Class 2 (ii)].

Title: Photographic product for the production of radiographs by a diffusion transfer process
IPC: G03C8/44
Filed: 1962-05-28
Abstract: 985,328. X-ray films. INTERNATIONAL POLAROID CORPORATION. May 28, 1962 [May 29, 1961], No. 20448/62. Heading H5R. A film for the production of radiographs by a diffusion transfer process comprises a photosensitive layer, an intensifying layer, and an image-receiving layer between them and laminated to at least the intensifying layer, the film incorporating a rupturable container of processing liquid. In the form shown, Fig. 1 has a laminated structure comprising a support layer 15, an intensifying layer 14, and an emulsion layer 12 in which the latent image is formed. This is developed by a layer 11 of processing composition, preferably in viscous form, a spreading sheet 10 assisting uniform application thereof. The developed image is transferred, by imbibition, to the receiving layer 13. The liquid layer 11 is applied by extrusion from a rupturable container (Fig. 2, not shown). A further support layer may be provided above the emulsion layer 12. Support 15 may be opaque or transparent, but if transparent must have a light-opaque backing. The intensifier layer thus remains as a component part of the finished radiograph, and acts as a " built-in " semi-opaque diffusing device, so that the radiograph may be viewed either as a reflection print or as a transparency. If the intensifier is such as to be activated also by ultra-violet light, then the finished print may be viewed under ultraviolet light as if it were a transparency. If the intensifier layer itself is of sufficient strength, the support 15 may not be necessary. Specifications 684,592, 684,593, 862,085 and 892,956 are referred to.
Patent GB-360053-A (GB)
Title: Process for the preparation of new violet dyestuffs of the anthraquinone series
IPC: C09B1/34
Filed: 1930-07-05
Abstract: Violet dyestuffs are prepared by introducing into anthraquinone derivations of the general formula <FORM:0360053/IV/1> wherein X represents a group replaceable by an arylamino residue, one m-halogenanilido group and sulphonating the compound thus obtained. The m-halogen substituent appears to cause a change of the dyeing shade to violet; the dyeings are fast to light and stable to chroming--which property is not possessed by the violet dyes derived from the oxyanthraquinones.  In an example 1-amino-2-methyl-4-bromanthraquinone is condensed with m-chloraniline and the product sulphonated; wool is dyed in pure violet tints, and by introducing a second sulphonic acid group into the molecule a much redder dyestuff is obtained. Specification 20718/00, [Class 2, Acids and salts, Organic &c.], is referred to.  The Specification as open to inspection under Sect. 91 relates to the production of reddish-blue to red-violet dyestuffs of the anthraquinone series by condensing anthraquinone derivatives which contain at least one group replaceable by an arylamino residue, with aromatic amines substituted by at least one halogen atom in m-position to the amino group, followed, if desired, by a sulphonating operation.  Thus the production of products of the following general formula is specified: <FORM:0360053/IV/2> wherein A represents an amino, substituted amino, hydroxy, or alkoxy group, C and D represent hydrogen, halogen or a sulphonic acid group, and X and Y a hydrogen and a sulphonic acid group respectively.  The following additional examples are given: (1) 1-Amino-4-hydroxyanthraquinone is condensed with m-chloraniline and the product sulphonated; it dyes wool violet-red; (2) 1-Oxy-2,4-dibromanthraquinone is condensed with m-chloraniline and the remaining halogen atom replaced by a sulphonic acid group by treatment with sulphite; it dyes wool violet; (3) 1-Amino-2,4-dibromanthraquinone is treated as in (2) and the product of sulphonation dyes wool reddish-blue; on replacing the remaining halogen atom by a sulphonic acid group by treatment with sulphite and phenol a product dyeing wool violet-blue is obtained; (4) 1-Amino-2,4-dibromanthraquinone-5-sulphonic acid is condensed with m chloraniline and the product treated with sulphite and phenol to give a reddish-blue wool dye.  It is stated that the m-chloraniline used in these examples may be replaced by other m-halogen substituted aromatic amines to give products dyeing redder shades than those of the dyestuffs not containing such a m-halogen atom in the arylido substituent residue.  This subject-matter does not appear in the Specification as accepted.

Title: Improved radio receiving apparatus comprising means for facilitating tuning
IPC: H03J3/12
Filed: 1938-07-11
Abstract: 499,359. Wireless receiving circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 11, 1938, No. 20555. Convention date, July 14, 1937. Addition to 481,858. [Class 40 (v)] In a radio receiver comprising a relay-operated tuning brake as described in the parent Specification, the changing over of the receiver circuits from the tuning to the reproducing condition is effected by a second relay, operating on actuation of the first. The tuning brake relay M comprising demagnetizing and operating windings 27, 26 is connected in series with the relay B and fitter choke 22 in the negative lead of the mains supply unit of a superheterodyne receiver. In the positions shown of the various switches, the receiver is tuned to a signal, and is reproducing. The brake magnet M is elastically suspended so that movement of the tuning knob in either direction displaces it to open the switch S. This removes a short-circuit across relay B which operates to change over the contacts b1 ... b6. Closure of b1 modulates the I.F. amplifier 5 with an alternating current of double mains frequency from 25 ; b2 opens to remove a short-circuit across resistance 30 which then provides a delay bias for the diode 8, 10, thus ensuring that only the maximum in-tune voltage across the sharply-tuned I.F. circuit 35 will be effective to produce a pulse of rectified voltage, corresponding to the mains frequency modulation, across load resistance 34 which is then applied by closure of b3 to the rectifier 32 over amplifiers 14, 15, thereby actuating relay A when the receiver is exactly in tune with the desired signal, contact b5 being closed ; the loudspeaker 18 is simultaneously disconnected by contact b6. Change-over of contact b4 shorts relay M through contact a which is opened by operation of relay A to operate the brake when the response of circuit 35 is a maximum, that is, when the receiver is exactly tuned to the desired signal. Relay B is immediately short-circuited by operation of contact a and contacts b1 ... b6 restore the circuits to the reproducing condition. The system may be made inoperative by operating push-button D and contact d in such manner as to bring B into operative condition before the selfshorting circuit of B is closed.

Title: Polymeric materials
IPC: C08J5/00
Filed: 1944-10-25
Abstract: Polytetrafluoroethylene is heated at a temperature of 50 DEG  to 500 DEG  C. in an oxidizing atmosphere for at least half an hour and is then formed into an article.  The oxidizing atmosphere may be air, oxygen, chlorine, bromine, ozonized air, nitric acid, nitric oxide or nitrogen trioxide.  The polymer in the form of powder, flakes or porous lumps may be passed through a heated zone on a conveyer, and films pressed therefrom followed by quenching in water. Alternatively, the article may be first formed and then heated.  For example, chips formed by compressing powdered polymer at room temperature are moulded by sintering at 380 DEG  C. and the mouldings are heated under pressure in chlorine.  Absorbed chlorine may be removed by heating in air.  The treatment improves the colour, tensile strength and dielectric strength.  The process may be used in insulating wires with fibres and films of the polymer.  The products are also useful as insulation in armature slots, commutator segments and V-rings of electric motors, and in sparking-plugs; as a dielectric for condensers; for radio apparatus and in battery separators.  Specifications 572,265, 574,688 and 583,418, and U.S.A. Specification 2,230,654 are referred to.
