Abstract: 1,073,337. Electromagnets. JOHNSON SERVICE CO. July 13, 1965 [Aug. 13. 1964], No. 29569/65. Heading HIP. [Also in Division G1] In an electromagnetic device a beam 27 is restored to a substantially undeflected position, when a force is applied to one end, by means of two pairs of electromagnets 13, 14, 15, 16 (only two shown) one pair lying on each side of a flexure hinge 31. The device shown is a pressure transducer. A strip 12 joins cores 14, 15 and a similar strip (not shown) joins cores 13, 15, while a permanent magnet 26 has one end joined to each strip between the pairs of cores. Armatures 21, 22 mounted on beam 27 are associated one with each pair of electromagnets so that flux from magnet 26 divides equally, one half passing along strip 12, through core 16, armature 22, core 15 and the second strip, while the other half passes through the other cores similarly. The coils are preferably connected in parallel and are wound so that the additional fluxes induced in one pair of coils supplement the permanent magnet flux while those induced in the other pair oppose the permanent flux so that a torque is exerted on beam 27. As shown, pressure acting on bellows 25 moves the opposite end of the beam to vary the pressure on carbon discs 41, 43 connected in series with the coils.

Title: Improvements relating to the feeding of muddy material into rotary kilns and the like
IPC: F27B7/14
Filed: 1927-11-07
Abstract: 284,276. Fasting, J. S. Jan. 27, 1927, [Convention date]. Rotary furnaces; charging; charges, agitating.-In a rotary kiln fed with wet slurry, the drying and distribution of the latter is facilitated by subjecting it, in the upper end of the kiln itself or in a chamber in front thereof, to a repeated flinging action. As shown in Fig. 1, an agitator projects into the kiln 1 and comprises a rotary shaft 6 carrying a series of discs 8 which extend into the slurry 4 retained in the upper end of the kiln by a ring 5. The last disc is formed of two plates between which are arranged pivoted wings 9. In a modified form of this construction the discs 8 operate in an enlargement of the kiln tube 1, there being provided at the entrance! to the main part of the kiln one or more radial vanes which dip into the slurry in the upper chamber and are formed with inclined guiding members to direct it into the kiln. Fig. 6 shows an arrangement in which the shaft 6 serves as the slurry supply pipe and is inclined so that the last discs 8 function to project the slurry into the kiln. In a further construction, the agitator is disposed in a downwardly tapering fixed chamber in front of the kiln, the last discs 8 being, in this case, replaced by a screw which feeds the dried slurry into the kiln. Fig. 9 shows another modification in which the slurry pipe 3 delivers into a mantle 20 secured to and spaced from the kilu 1, the annular space 21 thus formed serving for the passage into the kiln of any dried slurry which is deposited on and slides down the inclined base 24 of the smoke box 2. The inner end of the shaft 6 carries a propeller 27 to project the slurry into the kiln proper. The discs 8, as shown in Fig. 11, may be bent or corrugated at their edges, formed with perforations 25, or provided with wings or teeth 26.

[Also in Group VII] In a sewing machine a rock-shaft 53 and a rock frame 54 oscillate about parallel axes which are slightly offset from each other. A cylindrical member 72, carried at each end of frame 54, has a conical pin 71 at its inner end and a conical recess 78, the axis of which, is offset from the axis of pin 71, at its outer end. Member 72 has a head 74 formed with flats which engage ledges 76 on frame 54 to prevent rotation of member 72, and the latter is locked by a grub-screw 77. The pins 71 enter recesses 70 in the ends of shaft 53, and the recesses 78 receive conical-ended pins carried by a member 18. One of the latter pins is non- adjustably fixed, and the other one, pin 86, has a head 87 which screws into a bore 85. Pin 86 is locked by a grub-screw 88. To adjust for end play, screws 77 and 88 are loosened and head 87 is turned till shaft 53 rides correctly on pins 71, when screw 77 is tightened. Head 87 is then further adjusted till frame 54 rides correctly, when screw 88 is tightened.

Title: Improvements in removable metal crowns or bridges and methods for producing and affixing them
IPC: A61C5/73

Abstract: A removable dental crown is attached to a tooth by means of an intermediate layer or crown of thermoplastic material such as balata, artificial resin, mixtures of balata with rubber, guttapercha or resins, or a mixture of guttapercha and dammar gum.  The thermoplastic material is solid at the temperature of the mouth but softens at temperatures above 50 DEG  C.  According to one method of preparation thermoplastic material is placed in a metal crown, which is larger than the tooth to be fitted, and the whole heated and placed on the tooth which has previously been smeared with vaseline. After partial cooling the lined crown is removed and cooled in water, and the lining is removed from the crown, trimmed and cemented on the tooth and finally the metal crown is applied and, if necessary, cemented in place.  According to a modified process the lining is not removed from the metal crown after the initial moulding on the tooth. Factory made linings may be supplied.  Application of heat to the crown permits removal from the tooth if required.

Abstract: 141,322. Munroe, T. B. April 3, 1919, [Convention date]. Paper-machines; boards; pulp, adding special substances to.-In the production of a heat-insulating water-proof material for use in refrigerator cars or like purposes, a mixture of wood or other cellulose fibres and a water-proofing material such as resin with a large proportion of water is felted into sheets, which are dried in a moist atmosphere at a moderate temperature to remove substantially all the water, and a number of sheets are united to form a block of the required thickness. The process is preferably carried out by introducing the mixture into a tank 1, Fig. 1, from which it passes between a rotary drum 4 covered with foraminous material 10 and an endless travelling belt of foraminous material, and emerges as a continuous sheet. The proportion of water in the tank 1 is from 95 per cent to more than 99 per cent, whilst on emerging from the tank, the proportion is from 50 to 85 per cent. The water-proofing resin is preferably deposited on the fibres previous to admission to the tank 1 by mixing the fibres with a relatively small amount of water, and adding resin, size, and aluminium sulphate. The drying process is carried out in a moist atmosphere at a temperature not exceeding 350‹ F. so that the sheets are dried progressively from the centre outwards'. A fire-proofing material such as ferrous oxalate, or ferrous sulphate and oxalic acid, may be added in the tank 1, the ferrous oxalate decomposing during the drying process into water, carbon dioxide, carbon monoxide and iron. The sheets are cut to a suitable size and united, preferably with their edges offset to form interlocking tongues and grooves 21, 24, by means of nails 25, as shown in Fig. 2, or by wire stitching, or by asphalt cement.
