Filed: 1937-10-28
Abstract: 504,792. Stapling continuous filaments. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Oct. 28, 1937, No. 29482. [Class 120 (iii)] A sliver of staple fibre is produced from a band of continuous filaments by cutting the band, while it travels in the direction of its length, into sections which overlap one another by the action of two or more knives each of which is caused to move transversely to the direction of travel of the band and cuts partly through the band. As shown in Fig. 1, the band 1 is cut partly through its cross section at spaced intervals by rotating circular knives 2a, 2b which are oscillated about the pivots 3 and the knives may move in the direction of travel of the band, may be given a reciprocating motion, perpendicular or inclined to the direction of travel of the band, their cutting edges may be at right-angles or inclined to the direction of travel of the band, the knives may be guided in curved paths and single or double-edged band knives may be used. Four bands may be cut simultaneously by an arrangement of five rotating and oscillating knives. As shown in Fig. 3, the cutters 2a, 2b, 2c are arranged with an intersecting gill box 7, the bands being delivered to the cutting table by rollers 4 and to the gill box by rollers 5, the cut sliver being delivered from the box by a draft cylinder 6; the knives may be arranged between the sets of fallers of the gill box and arranged to move with the fallers in the direction of the travel of the stiver.

Title: Improvements in and relating to mechanism for resolving and compounding velocities
Filed: 1921-11-08
Abstract: 188,527. Booth, C. H. Nov. 8, 1921. Course-recording apparatus.-In a device for resolving a velocity such as a ship's speed into two rectangular or other components, of the type in which a sphere is rotated at a speed proportional to the velocity, and speeds proportional to the components are taken from the spherical surface, the plane of the sphere's rotation is made to correspond with the direction of the velocity to be resolved. The sphere 1 is supported by a pair of driving wheels 2, 2A and by two pairs of driven wheels 3, 3A, 4, 4A, the planes of the three pairs of wheels being mutually perpendicular. The wheels 2, 2A, disposed at the extremities of a vertical diameter of the sphere. are journaled respectively in frames 8, 8A which are rotatable about that diameter in the main framework which carries also the bearings for the wheels 3, 3A, 4, 4A and for a shaft 7 carrying pinions 6, 6A meshing with gears 5, 5A secured to the frames 8, 8A respectively. The wheels 2, 2A are given a rotation proportional to the ship's speed as follows. The movement of the ship through the water is arranged to make and break a contact 29, Fig. 5, at a rate proportional to the ship's speed, and a solenoid 17 is thereby energized and de-energized at the same rate. The moving core of this solenoid is connected at 18 to a pair of bell-crank levers 16 each of which is arranged to actuate a spring-controlled plunger 15 carrying a pawl 14 which drives a ratchet wheel 13 secured to the wheel 2 or 2A. To make the plane of rotation of the sphere 1 to correspond with the direction of the ship's movement. the plane of the wheels 2, 2A is varied by rotation of the shaft 7 through worm gear from the shaft 11 of a step-by-step electric motor 12 connected to the repeater transmission 30, Fig. 5, of a gyroscopic compass. The shafts of the wheels 3, 3A are fitted with chain wheels connected by a chain 23 and their rotation is transmitted through bevel gears 32, 33, even gear wheels 34 and a screwed shaft 31 to a nut 35. The shafts of the wheels 4, 4A are fitted with chain wheels connected by a chain 24 and their rotation is transmitted through a feathered shaft 37 and bevel gears 38, 39 to a shaft 36 which is journaled in the nut 35 and is screwed to engage a nut 40 carying a pencil 41 which thus draws a record of the ship's course on a surface 42. An additional pair of wheels may be provided to bear on the sphere 1 for use in resolving the velocity into components other than rectangular.

Title: A new dyeing process for wool, silk and other protein fibres
IPC: D06P1/00
Filed: 1950-12-08
Abstract: Before dyeing, wool, silk and other protein fibres are treated in a cleaning bath containing a wetting agent and an inorganic or organic acid, the acid strength being adjusted to correspond to a strength of the order of and up to 0.7Be sulphuric acid.  The cleansing bath may be prepared with hard water at room temperature.  Specified acids include sulphuric, hydrochloric, phosphoric, formic and acetic. Specified wetting agents include the alkylsulphates, alkylsulphonates, alkylarysulphonates, their chlorinated derivatives, amidesulphates, alkyl phosphates, cetyl trimethyl ammonium bromide, cetyl pyridinium bromide and other cationic agents, and nonionic agents such as those obtained by condensing ethylene oxide with compounds containing a long hydrophobic hydrocarbon chain and an active hydrogen atom.  When using cationic and non-ionic agents, alcohols, phenols, amines, aldehydes and other polar compounds or solvent hydrocarbons may be added to the bath.  The dyebath may be prepared in hard or soft water without addition of sodium sulphate, acids or levelling agents; if any precipitation occurs in the dyebath an anionic surface active agent may be added to ensure solubilization and dispersion.  In an example (all parts by weight) a bath is prepared from one part of sulphuric acid, five parts of a 10 per cent aqueous solution of an anionic detergent such as sodium lauryl sulphate and 200 parts of water.  Wool is pretreated in this bath and then dyed.

Title: Improvements in or relating to coin separators
Inventor: GOTTFRIED JOHN
Filed: 1953-10-31
Abstract: 737,638. Testing and sorting coins in coinfreed apparatus. NATIONAL REJECTORS, Inc. Oct. 31, 1953, No. 30145/53. Class 27. A coin separator has a pivoted counterweighted cradle 24 with spaced gauging projections 26, a pivoted feeler 37 for arresting washers or coins having abnormal surface deformations and a camming surface 32 on the cradle for holding the feeler out of the coin passageway between the frame 10 and a hinged wall 12 until the cradle receives a coin of correct size and weight and begins to tilt to deliver the coin to a runway 42. The feeler has an arcuate coin-engaging surface and thus engages the moving coin with point contact so that frictional forces are reduced; also, since the feeler follows a bent path along the coin, a greater area is explored. The coin-engaging portion of the feeler is inclined transversely of the coin passageway and is. directed oppositely to the movement of the coin so that shaking of the separator will wedge the feeler into tighter engagement with the coin. The feeler may be biased into the coin passageway by a counterweight, or by spring or magnetic force. The speed of the coins on the runway 42 is retarded by a permanent magnet which is spaced from a plate 44<SP>1</SP> so as to form a coin passageway; coins of correct electrical conductivity will leave the runway with sufficient speed to rebound from a deflector 45 so that they pass between stops 46, 47 into an accepted coin shoot 49, while coins of incorrect conductivity will either bounce from deflector 45 against stop 48 or 46 or fall direct on to stop 46 and be directed by a bent deflector 51 through a cut-away part of a partition 54 into a rejected coin shoot 53. Clearing apparatus. Depression of a clearing plate cams the wall 12 away from the frame 10 and a pusher bracket 56, which is pivoted on lugs 58 extending through holes in the gate and is normally held out of the coin passageway by a spacer 62, will remain close to the frame under the action of a spring 60 and will strip any coins retained on the feeler, so that they can be directed to the rejected coin shoot 53 by a clearing lever pivoted on the spacer 62.

Abstract: 1,048,276. Combustion chambers operating under pressure. THIOKOL CHEMICAL CORPORATION. July 30, 1963, No. 30167/63. Heading F1L. [Also in Division F4] Apparatus for generating steam by catalytically converting hydrogen peroxide to steam and oxygen and supplying hydrogen to react with the oxygen consists of an elongated cylinder including a decomposition chamber 34 and a combustion chamber 35 having a water jacket 36. A catalyst 40, e.g. a silver screen, is mounted in front of the chamber 34 which contains a hydrogen preheating coil 44. In operation hydrogen peroxide from a nitrogenpressurized tank passes through a perforated plate 43 and the catalyst 40 wherein it decomposes to steam and oxygen at a high temperature. Hydrogen flows through the coil 44 and enters the chamber 35 through perforations as shown, the hydrogen immediately burning with the oxygen. Water flowing through the jacket 36 enters the chamber through perforations 37 to flash into steam. Pure steam discharges from the chamber in a saturated or superheated state. The steam may be used as the motive fluid in a jet vacuum pump 46 from which it exhausts to a condenser 47 whence the condensate is returned to the apparatus by a pump 48. The pump 46 may be used in an emergency pumping system of a naval vessel or in any system where large quantities of liquid must be handled but is of particular application to the testing of rocket engines serving to exhaust gases therefrom to simulate high altitude conditions.
