Title: Improvements in crushing machines
IPC: B02C13/282
Filed: 1923-10-03
Abstract: 226,889. Tugwood, R. J., (Jeffrey Manufacturing Co.). Oct. 3, 1923. Impact pulverizers. - In a crushing- machine with a rotor comprising rigidlymounted teeth or projections spaced apart circumferentially and longitudinally, abutment means is provided for engaging large particles of the material to be crushed and confining them to the upper side of the rotor, only the crushed or small material being permitted to pass into the lower portion of the casing in which the screen is situated. As shown, the coal &c. passes down the feed-hopper 38 on to a rotating plate 40 whence it is directed by a scraper attached to the side wall 39 into the breaking- chamber 17 above the rotor which consists of a number of spaced discs 10 secured to a horizontal shaft 8 and having apertures through which pass longitudinal rods 12 carrying the crushing arms or projections. The crushing- members are each shaped to form three equallyspaced arms 13, 14, 15 each pierced by an aperture 16 to receive one of the rods 12. Two of the arms 14, 15 project into the space between two of the discs 10 and are engaged by two of the rods 12 to hold the third arm 13 rigidly in radial extension beyond the periphery of the discs 10. The housing 2 which encloses the upper half of the rotor and contains the chamber 17 is formed of end walls 18 bolted to the flanges 6 of the base frame 1 and joined together at the rearward side of the chamber 17 bv the casing-plate 19 and hopper-plates 20. At the forward side of the housing, the walls 18 are held in spaced relation by a draw-bolt 21 upon which is suspended a plate 22 to close the forward side of the chamber 17. A goose-neck bracket 23 at the lower side of the plate 22 is engaged by an adjusting-screw 24 carried in a nut 25 on the frame 1. The plate 22 is protected by a lining 26 having at its lower edge an abutment shelf 27 the upper surface of which is substantially radial to the rotor and extends in close proximity to the path of the ends of the arms 13. The shelf engages large particles of coal &c. and prevents them from passing into the crushing-chamber until they have been broken down by the arms 13. A semicylindrical screen is provided at the bottom of the casing and preferably consists of longitudinally-extending grate-bars 28. The forward section 29 of the screen is rigidly supported by flanges 30 on the frame 1, and the rearward section 31 is supported by a frame 32 hinged upon a shaft 33 and is held in working position by toggle-levers 34 fixed to a shaft 35. By means of a weighted arm 36, the shaft 35 can be turned and the section 31 of the screen dropped to permit of the ejection of any unbreakable objects. The feed-plate 40 is mounted on a vertical shaft 41 driven through worm gearing 44, 45 from a horizontal shaft 46 driven bv a belt 48 from the shaft 8. Shield plates 50. 51 intercept fragments of coal projected from the chamber 17, and a sliding plate 52 beneath the hopper 38 controls the rate of feeding. Specification 215,201 is referred to.

Title: Improvements relating to electric mercury or like switches operated by tilting or rotation
IPC: H01H29/24
Filed: 1936-09-09
Abstract: 483,227. Mercury switches. CIANCHI, A. Sept. 9, 1936, No. 24641. [Class 38 (v)] A mercury switch comprises a gas-charged vessel 1 connected by the part 10 of electrodes 4, 4<1> to conical bearings 2, 2' so as to be resiliently mounted inside a second envelope 9 which is formed with a handle part surrounding a branch 1<1> of vessel 1. Current is led in through the bearings 3, 2, 3<1>, 2<1> and on inverting the vessel, to place the branch 1<1> uppermost, the mercury in the branch flows into the main part of the vessel and connects electrodes 4, 4<1>. On restoring the vessel to the position shown in the Figure, circuit is temporarily maintained by mercury retained in a subdivided trough 11 of refractory material] having holes through which the mercury drains away causing a number of breaks in series over the edges of walls 12. In a modification, the mercury switch is resiliently supported by its electrodes on the inside of the cover of a switch box, which is tilted to operate the switch, current being led in through the pivots. A projection on the cover engages a bowed spring to give a snap action and the ends of the spring serve to hold the cover in position. If the switch is charged with neon it would glow when in the off position.
Patent GB-370805-A (GB)
Title: Improvements in change-speed gear mechanism
IPC: F16H3/08
Filed: 1931-09-03
Abstract: 370,805. Change-speed gearing. MAYBACH-MOTORENBAU GES., Friedrichshafen-on- Bodensee, Germany. Sept. 3, 1931, No. 24703. Convention date, Nov. 12, 1930. Addition to 367,220. [Class 80 (ii).] According to the parent Specification, gears 1 .. 8, such as are shown in Fig. 1, are used to effect eight forward speed by the movement each to two end positions of a double clutch B, a pair of coupled clutches D, E, and the clutchended gear 8. The dogs of the clutches B, D, E have bevelled ends which ratchet over one another preventing engagement until there is a change of sign between positive and negative of the relative speeds of the teeth as described in Specification 298,186, [Class 80 (ii), Gearing, Variable-speed &c.]. If an attempt is made at a simultaneous change of all the clutches from the position of Fig. 1, in order to bring train 3 .. 6 into action, ratcheting takes place between the ends of the dogs of the clutch E and the ends of the dogs of the clutch ends of the gear 5, and continues until the gear 5 moves more slowly than the clutch E. But since the speed of the gear 5 is maintained from the vehicle road wheels through the tail shaft G1, the ratcheting would continue, preventing the clutch engagement indefinitely. At the same time, and for the same reason, the clutch B is prevented from engaging the rapidly decelerating clutch end of the gear 3. To enable the movements of the clutches to be completed, the countershaft V, Fig. 2, is adapted to be accelerated by a friction clutch H in splined connection J with the gear 5. Gear 3 being thus accelerated, the clutch B can slip into engagement with it, and the completed engagement of the clutch E follows, possibly aided by engine acceleration. The friction clutch H may either be operated by a lever K and suitable mechanical or pneumatic controls, or directly by the movement of the clutch E through a suitable connection. Alternatively, the auxiliary friction clutch may be arranged in the main shaft train.

Title: Method of processing photographic silver halide material
IPC: G03C5/29
Filed: 1971-04-19
Abstract: 1287547 Development of black-and-white negative silver halide photographic material FUJI PHOTO FILM CO Ltd 19 April 1971 [16 March 1970] 24738/71 Heading G2C An exposed black-and-white negative photographic silver halide material is developed, partially bleached with a solution containing an oxidizing agent and an inorganic halide at a pH insufficient to completely dissolve or oxidize the silver and then given a second development in a black-and-white developer. The first developer may comprise hydroquinone and sodium sulphiteparaformaldehyde adduct and may contain ascorbic acid and/or sodium sulphite (with development). The pH of the bleaching solution is preferably not less than 1. In the case of dot images "dot etching" is not required after development, since the quality of the dot image is improved to such an extent that a sharp printed image may be obtained, and also silver halide may be saved by thinning the emulsion layer or by decreasing the content of silver halide in the emulsion layer,

Title: Improvements in and relating to yarn tensioning devices for textile apparatus
IPC: B65H59/16
Filed: 1952-10-03
Abstract: 721,643. Yarn tensioning devices. CELANESE CORPORATION OF AMERICA. Oct. 3, 1952 [Oct. 6, 1951], No. 24861/52. Class 120 (2). A yarn tensioning device comprises a wheel or pulley adapted to be engaged and driven by a yarn drawn past it, a magnet and an electric conductor that are rotatable relatively to one another by the connection of one of them to said wheel or pulley, the conductor extending into the field of the magnet so as to apply to the wheel or pulley a braking force whereby tension is imparted to the yarn, the field and the conductor being substantially symmetrical both about the axis of the wheel or pulley and about a common plane at right-angles to said axis so that the braking force is substantially without components parallel to or radial of said axis. As shown a wheel 11 around which yarn may pass is fastened to a shaft 17 mounted for rotation in oil impregnated sintered metal bearings 18 and 19 and bearing on a hardened steel ball 22. The bearings 18 and 19 are housed in a bushing 20 having a base plate 24 fitted thereto said base plate supporting an electromagnet 25. The electromagnet 25 consists of a coil 26, an upper pole piece 28 and a lower pole piece 29 each having, projecting downwards and upwards respectively, sets of teeth 31 and 32 which are interdigitated with respect to each other. Also mounted on the shaft 17 is a fitting 33 which carries a light aluminium flange 34. A ring 36 of ferromagnetic material is mounted inside a depending portion 37 of the flange 34 and is concentric with the circles of teeth 31 and 32. During the use of the device a current is caused to flow through the coil 26 producing a magnetic field between the teeth 31 and 32. Movement of the yarn 12 around the wheel 11 causes rotation of the ring 36 with respect to the magnetic field which action causes a braking effect on the wheel 11 and thereby imposes a tension on the yarn 12.
