Title: Improvements in the method of knitting garments on straight-bar machines and in means therefor
IPC: D04B11/00
Filed: 1935-11-29
Abstract: 464,705. Knitting-machines. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. Nov. 29, 1935, No. 33097. [Class 74 (ii)] A straight-bar machine for knitting a course at an intermediate point in a garment comprises a needle bar with butted needles, a hand-operated cam box on which is mounted a thread carrier, bits on which the courses are drawn and knitted, a presser bar which can be moved away from the needles, and a detachable bar with transfer points. Needles A have butts engaged by a cam D sliding on rods E, and operated by a handle D2. The cam box carries a bar J which holds all the needles up when the box is at the right of the machine, to facilitate running-on. A presser-bar K is mounted on spring held bell-crank levers L, L<2>. carrying a bar G, with raised parts G<1> at each end engaged by a roller G<2> on the cam box D, so that the pressure is retracted at each end of a traverse. The bits P are mounted on a rod P carried by arms Q on a spring-held shaft Q<1> mounted in the ends of links R on a shaft S which is operated by a lever T<1> to raise the bits. Movement of the bits P between the needles is controlled by cams D <6>, D<7>, bearing on the shaft Q<1>, and operated by the swinging to right or left of the cam-handle D<2>, which is mounted on a pivot for this purpose. In operation, a garment placed in a shield Y is run on to the needles, the cam is traversed to the left to knit a course, the front part of the garment is turned back, the needles are raised, a bar V<1> carrying transfer points V is placed in position in brackets W, and the bits P are raised to transfer the loops to the points V, for removal to another machine.

Title: Improvements in or relating to machines for folding and measuring cloth
IPC: B65H45/101
Filed: 1955-11-18
Abstract: 789,192. Folding fabrics. GILLET-THAON. Nov. 18, 1955 [Dec. 4, 1954], No. 33128/55. Class 42 (2). In a cloth-folding machine, operation of a seam detecting device disposed in the path of cloth pieces seamed into a continuous length and being fed to the machine, actuates means whereby a vertically slidable table is lowered and folded cloth thereon is ejected. As shown, cloth A passed by a drive roller 15 and guided by a roller 14 is stacked in superposed folds on a table 10 (carrying smooth plates 52) by a reciprocating arm 13 the travel of which (and therefore the length of each fold) may be adjusted. A seam in the cloth causes a finger 17 to operate a switch 19 thereby energizing a system of electrical relays (which have adjustable time-lags to compensate for the travel of the detected seam to the end of the table) to energize a motor 25 which drives through pulleys 26 and 28 and belts 27 to lower the table 10 (by means of chains 30 by which crosspieces 29 are attached to cams 31) until it is level with the top of an inclined plane 16 whereat the folded cloth is ejected by movement of an endless belt 39 of rubber or like flexible material which is supported on guide rollers 40, 41, 42, 43 and driven by a slidably mounted roller 44, pulleys 45 and 47 and belts 46 from a motor 48 itself actuated through a relay by a cam-operated contact and stopped thereby when the displacement of the belt 39 is sufficient to eject the cloth. The spring 32, which during the lowering of the table was compressed by the rotation of the cams 31, then (with the motor 25 de-energized by operation of a cam 33- operated limit switch) reverses the drive to restore the table to its raised position. During the vertical movements of the table 10, the feed of the cloth A is interrupted, to avoid accumulation thereof in the space between the roller 15 and the machine entry, by means of an electromagnetic clutch 35 which is operated through a relay by the engagement of a cam 38 with an electrical contact. The actuation by the finger 17 of the main relay system may be selective, e.g. operative only after passage of two successive seams as may be required in the folding of doubled pieces, according to the setting of a micro-contact (in the relay circuit) with respect to a needle on a dial cr counter operated by the machine, Fig. 2 (not shown). On breakage of the cloth or passage of a false seam a detecting roller bearing on the surface of the cloth closes a relay circuit to stop the machine.

Title: Improvements in the manufacture of alloy steels
IPC: C21C5/28
Filed: 1948-12-23
Abstract: In a method of manufacturing alloy steels in which chromium, tungsten, molybdenum or manganese is added to a bath of molten metal, this addition metal is added in the form of its ore or oxide and pure oxygen or a gaseous mixture containing at least 70 p  per cent of oxygen is blown into the bath thereby raising its temperature and rendering the bath sufficiently fluid for the rapid completion of chemical reactions and to facilitate the separation of nonmetallic inclusions.  The ore or iron oxide may be added to the bath before blowing to effect a preliminary oxidation of silicon and manganese present.  Any of the desired addition metal which is oxidized by the blowing operation may subsequently be reduced out of the slag by addition of a reducing agent such as silicon.

Title: Improvements in or relating to electromagnetic actuators
IPC: H01F7/14
Filed: 1965-08-03
Abstract: 1,113,832. Visible signalling apparatus. DACO INSTRUMENT CO. Inc. 3 Aug., 1965 [6 Aug., 1964], No. 33220/65. Heading G4F. [Also in Divisions E2 and H1] A latching device for a rotary electromagnetic actuator comprises a yoke 48 mounted on the actuator 34 carrying a shaft 61 arranged for reciprocating motion parallel to the rotational axis of the actuator 34, shaft 61 carrying a bracket 54 arranged in one position of the shaft to engage a member (40) on the actuator and, in a further position of shaft 61, to release the member (40). The actuator is preferably a two-position indicator similar to that disclosed in Specification 988,819 in which energization of a solenoid 26 creates a field about poles 12, 14 and hence causes rotation of an armature 24 and an indicating disc 30 against the bias of a spring 28. A ferromagnetic latching rotor 40, secured to a rotor shaft 18, is held in the deflected position by a detent 120 mounted on a bracket 54 carried by the shaft 61 until released by manual actuation of a pushbutton 63. Bar magnets 76, 78, magnetic member 82 and non-magnetic spacer 80 are mounted on bracket 54 so as to provide alternative or additional latching of rotor 40. Alternatively, rotor 40 may be formed from bar magnets 90, 92 oppositely polarized with respect to 76, 78. Actuation of push-button 63 to the left then causes the pole of magnet 78 to come adjacent a like pole of magnet 90 and hence helps to repel the rotor to its normal position. Reference has been directed by the Comptroller to Specification 988,819.

Abstract: 367,004. Ribbon resistances ; couplings. LIGHTFOOT, E. N., Wanwatosa, Milwaukee, Wisconsin, U.S.A. Nov. 5, 1930, No. 33284. Convention date, Feb. 19. [Classes 37 and 38 (i).] A resistance ribbon is supported by being bent back and forth between two sets of metallic supports mounted on, and insulated from, respective metal rods. Between endplates 35, 36, Fig. 1, are mounted a pair of rods 20, 21 covered with tubes of insulating material such as laminated mica. On these are strung metal plates 23 alternately with insulating washers 33. The plates 23 are shown in Fig. 6, and have a hole 24 fitting over the insulating tube, and a pair of deep notches 25, 26 which support the resistance ribbon while permitting expansion. The plates 23 are arranged to extend in diametrically opposite directions so as to provide supports for two resistance ribbons 45, one on each side of the rods 20, 21. The assembly is tightened by nuts 29. Each ribbon 45 is bent as shown in Fig. 5 and, if thin, may have reinforcing corrugations 46 at the bends and beads 47 between the bends. The bends engage the notches 25, 26 in the plates 23. The terminal elements, shown in Fig. 7, comprise stamped plates 48, 48a having stampedout lugs 49, 49a which engage perforations 27,28, Fig. 6, in the plates 23. The lower ends of the plates 48, 48a have bowed portions engaging the bends in the ribbon 45. At their upper ends, the plates 48 have corrugations 51, 52 for clamping wires of different sizes. Between the plates 48, 48a is a plate 53, Fig. 9, having an offset lower portion and a partially severed portion 56 which engages the notch 25 or 26 supporting the bend of the ribbon. Perforations 73 permit the attachment of metal tags indicating the value of the resistance at the different tapping points. One of the plates 48, 48a may be omitted. For connecting two resistance strips in parallel, metal plates 64, Fig. 11, having flat offset portions 65, 66, and a connecting portion 67 may be employed. Plates 48, as shown in Fig. 7, are employed in co-operation with the portions 65, 66, the intermediate portion 67 being perforated to take a bolt by which a cast-iron terminal clamping element is secured thereto.

Filed: 1949-12-29
Abstract: 686,685. Spring suspensions. CLERK, R. C. March 29, 1951 [Dec. 29, 1949], No. 33288/49. Class 108 (ii). In a suspension means for a motor vehicle road wheel employed for steering, driving and braking and of the kind including a steering pivot member coupled at points above and below the road wheel axis respectively to two levers mounted on the vehicle frame, the steering pivot carrying a wheel hub directly connected by a cardan shaft to transmission gearing which is mounted on the vehicle frame and which includes a road wheel brake, the coupling by which the steering pivot member is connected to the upper suspension lever is permitted to move to a limited extent relatively to the vehicle frame horizontally or substantially horizontally in a direction having at least a major component in the fore-and-aft direction. In the arrangement shown, in which a lower wishbone link 15 is pivoted about a horizontal axis to a frame member 11 and is sprung against frame members 13, 14 by a suspension strut 12, an upper wishbone link 17 is pivoted on a cross-piece 20 of a T-shaped member 21, the stem 22 of which is journalled in a bearing 23 on the chassis frame. The crosspiece 20 co-operates with stops 27, 27A on the frame and is biased towards a braking stop 27A by the stem 22 which is formed as a torsion spring and is anchored by a bolt 28. The torsion spring may be formed by a rubber disc or bush bonded to two relatively rotating annular or cylindrical surfaces. The outer ends of the wishbone links are formed with sockets 32, 33 which engage ball-ended pins 30, 31 on a drum-shaped member 29 forming part of a steering pivot member. A steering lever 34 projects forwardly of the steering pivot member and is connected by a ball-joint above the level of the lower wishbone link, to a transverse track rod link (not shown). The lever 34 may project rearwardly and in this case is connected to the track rod link below the lower wishbone link. A suitable linkage may connect the crosspieces on opposite sides of the vehicle. In an alternative arrangement the suspension may comprise upper and lower trailing arms to which the steering pivot is connected directly or through a rigid extension joining together rearward ends of the arms. The upper arm is out of parallel with the chassis and is telescopic and resiliently biased towards its rearward limit. The arm may comprise telescopic tubes or it may have its forward end pivoted to a link which is rigid with one end of a torsion bar disposed transversely of the vehicle.

Title: Method of making positive polymeric images
IPC: G03F7/004
Filed: 1974-07-29
Abstract: 1448047 Photopolymerization EI DU PONT DE NEMOURS & CO 29 July 1974 [1 Aug 1973] 33428/74 Heading G2C A positive polymeric image is made from an element comprising a substrate carrying a layer of a photopolymerizable composition containing a compound capable of addition polymerization by chain propagation initiated by free radicals, (2) a nitroso dimer which is photodissociable to nitroso monomer, and (3) an organic free radicalgenerating system activatable by actinic radiation which does not cause appreciable photodissociation of the dimer, the method comprising imagewise exposing the layer of photopolymerizable composition to radiation that causes dissociation of the nitroso dimer, exposing at least the unexposed portion of the layer to the said actinic radiation, and developing the resulting positive polymeric image. Photodissociation is intended to indicate that the imagewise exposure converts the dimer, which is not itself a polymerization inhibitor, into one or more inhibitors of free radical polymerization. The conversion is thought to be brought about as a result of photo-dissociation of nitroso dimer into nitroso-monomer. The photodissociation usually occurs on exposure to UV radiation, generally of wavelengths less than about 3400A and the actinic radiation exposure, to effect the polymerization is effected at wavelengths greater than about 3400A. Suitable unsaturated compounds include unsaturated esters of polyols, (including those of polyethylene glycols), amides especially of α-methylene carboxylic acids and α, w-diamines, vinyl esters, styrene, and unsaturated aldehydes such as hexadienal. The free radical generating system can furnish free radicals directly when activated by radiation or after having been caused to do so by a sensitizer which is activated by the radiation. Such compounds include aromatic ketones; benzoins; 2, 4, 5-triceryl-imidazole dimers, optionally with 2-mercaptobenzoxazole. Redox combinations e.g. Rose Bengal/2-dibutylaminoethanol can be used. The compositions can also contain polymer binders.
