Title: Improvements in or applicable to looms for weaving tufted pile fabrics
IPC: D03D39/06
Filed: 1924-03-31
Abstract: 239,250. Platt Bros. & Co., Ltd., and Austin, F. W. March 31, 1924. Creel - frame arrangements; pile-fabric looms.- Relates to means for guiding and driving the tubeframe carrying chains 22, which carry tube frames &c. to and from the place 42 where the tube frames are removed from the chains for insertion of tuft yarns into the fabric being woven and are then returned to the chains, the chains being held stationary at this place from time to time for this purpose. The chains pass around sprocket wheels 49 on a shaft 48, which is intermittently driven by ratchet gearing &c., the remaining portions of the chain being driven intermittently, or as shown continuously by passing around sprocket wheels 211, 33 on shafts 201, 24 driven by worm gearing &c. The chains also pass around idle guiding sprocket wheels. The supporting framework includes girders formed of two channel irons spaced apart to receive ribs on the lower faces of the bearings for the shafts of the sprocket wheels. The sprocket wheels 33 engage both the upper parts of the chains and also the lower parts thereof, which are guided by curved guides 38 connected by links 45, the chains forming loops &c. 46 between the guides. These are formed with semicircular or other guide-channels to receive the chain rollers &c., and are arranged to allow of the passage of the parts by which the tube frames are attached to the chains. The guides are suspended by means of rods 37 from the shafts 24, the sprocket wheels each fitting between two guides. In a modification, the two guide-channels are formed in one guide, which has a gap at the top to accommodate the teeth of the sprocket wheel to allow it to engage the chain below it. The shaft 48 carries upwardly-extending adjustable links 50 having blocks forming bearings for a shaft 51 furnished with sprocket wheels 52 for engaging the chains 22 at two places as shown, so as to cause equal lengths of the chains to approach and recede at these places. Square projections on the blocks fit in corresponding sockets on brackets on curved guides 53, which maintain the chains in contact with the sprocket wheels 52. These wheels can move bodily about the shaft 48 to allow for variations in the lengths of the respective parts 56 of the chains due to the stoppage at times of parts of the chains for the removal of the tube frames. Two or more chains may be used, and tube frames placed in line two or more together may be employed. In the drawings, three chains are shown, each shaft being furnished with three sprocket wheels. Specifications 240,400 and 242,682 are referred to.

Title: Method of producing halogen-substituted derivatives of aliphatic hydrocarbons
IPC: C07C17/093
Filed: 1949-03-25
Abstract: Alkyl halides are made by reacting at boiling temperature an alkyl chlorsulphonate Cl-SO2-O-R with excess hydracid HX in the form of an aqueous solution, X being chlorine, bromine, or iodine, and R being an alkyl radicle having three or more carbon atoms, that may be unsaturated, and may contain one or several halogen atoms.  The alkyl chlorsulphonate may be obtained from sulphuryl chloride and the corresponding alcohol and used without isolation.  In an example, polymethylene chlorobromides of the formula Cl.(CH2)nBr, where n is a number from 3 to 10, are obtained from the chlorosulphonates Cl.SO3(CH2)nCl by boiling with hydrobromic acid.  The alkyl chlorosulphonates are obtained by the action of sulphuryl chloride on the alcohols ROH or halogen substituted derivatives thereof.  The Specification as open to inspection under Sect. 91 also describes the preparation of methylene chloride, chlorobromomethane, and chloroiodomethane from chloromethyl chlorsulphonate and hydrochloric, hydrobromic, and hydriodic acids respectively, and of 1-chloro-2-bromo-ethane and 1-chloro-2-iodoethane from b -chloroethyl chlorsulphonate and hydrobromic or hydriodic acids respectively. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to differential fluid pressure gauges used for measuring the flow of fluids
IPC: G01F1/37
Filed: 1932-03-21
Abstract: 398,558. Differential pressure gauges. ELECTROFLO METERS CO., Ltd. and ENGEL, F. V. A. E., Abbey Road, Park Royal, London. March 21, 1932, No. 8359. [Class 106 (ii).] Comprises a gauge for use with flow meters in which the float is in part formed so that the sides are relatively close together and converge upwardly at a relatively small angle to one another so as to offer small resistance to the mercury or other liquid employed. A cylindrical vessel 1 containing mercury 2 is provided with a horizontal partition 3 and carrying a tube 4 extending downwards into the liquid thus dividing the vessel 1 into two portions or chambers. A pipe 5 communicates through a duct 6 with the lower chamber and a pipe 7 with the upper chamber. The float 10 is provided with a cylindrical portion located within the tube 4 and a shaped portion 12 outside it. The portion 12 is of tubular shape, the outer and inner walls converging to a sharp upper edge, in order to obtain a straight line law reading from a flow which is proportional to the square root of the pressure difference. Both portions may be shaped to give the required result. In some cases the inner or outer surface of the part 12 may be cylindrical and the other surface shaped to secure the required movement. The part 11 may be provided with a stem or rack 14 connected in known manner to indicating, recording, or integrating mechanism. The portion 12 in the zero position may protrude slightly above the mercury level or be provided with a thin collar on the upper end to avoid zero errors due to mercurv meniscus effects and oscillations when the surface of the mercury is broken. A valve 16 arranged in the partition 3 enables the pressures in the two chambers to be equalized, and the return of any mercury forced into the upper chamber by abnormal pressures. Specification 327,065, [Class 106 (ii), Dynamometers &c.], is referred to.

Title: Improvements relating to electrical positioning apparatus
Inventor: ROBINSON EDWARD HOWARD
IPC: B23Q15/00
Filed: 1957-03-14
Abstract: 892,973. Positioning apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 16, 1958 [March 14, 1957 (2)], Nos. 8386/57 and 8387/57. Class 40(3). In apparatus for positioning a member, e.g. a workpiece, according to reference markings thereon, light from a vibrating light source is directed on the markings and signals produced in a photo-cell in response to the light reflected from the markings act on a servomotor which positions the member so that a reference mark coincides with the mean position of the light image. A workpiece 1, e.g. a commutator being undercut, is connected for rotation by a servomotor 4 via gearing 3. The image of a narrow slit at the outlet of a light source 6 is projected via the workpiece to a photo-cell 7. The slit is formed parallel to the dark insulation lines between commutator segments and is vibrated by a unit 8. Equal movement of the slit imageto either side of a dark line produces a signal from the photo-cell at twice the frequency of vibration, if the slit image movement and a line are not symmetrically positioned, the cell produces a component at the fundamental frequency of vibration of phase dependent on the sign of the asymmetry. The fundamental component is amplified 16 and applied to the servomotor which drives the workpiece to a position in which the line coincides with the mean position of the vibrating light image. When positioned a cutting tool 9 attached to an arm 10 is advanced by air pressure under the control of an air relay 12. At the end of the cutting traverse, a stop 15 bearing on a cam sleeve 13 opens a switch SW11 which causes the arm to retract. In the retracted position the arm operates a switch SW9 which reverses the phase of the supply to vibrator 8 via relay, contacts RL 3/3 and RL 3/4, this reversal produces a signal which rotates the workpiece away from the index position. In addition, a "creep" voltage is applied to the amplifier which drives the servomotor and rotates the workpiece towards the next index position. On approach to the new position the light generated signal opposes the "creep" voltage and the servomotor is brought to a halt whereby contacts RL3/3 and RL3/4 change over, the phase of the vibrator supply is reversed and the "creep" voltage is disconnected from the amplifier. The light generated signal then acts on the servomotor to position the workpiece in its new index position. The output of a tachometer 5, driven by the servomotor, is applied to a relay RL5 via amplifier 17 and prevents any machining operation until the reference mark has reached its index position.
