Title: Improvements in or relating to the control of epicyclic variable speed gears
IPC: F16H63/30
Filed: 1945-03-05
Abstract: 591,153. Controlling change-speed and reverse gearing. LAGONDA, Ltd., and BENTLEY, W. O. March 5, 1945, No. 5490. [Class 80 (ii)] The control of a separate mechanical epicyclic reverse gear 10, Fig. 3, is interconnected with that of an associated multiple epicyclic change-speed gear G, Fig. 1, controlled by electromagnetic clutches and brakes, so that introduction of reverse automatically selects a predetermined ratio, e.g., third or direct-drive in the change-speed gear, whereby a desired overall reverse ratio is obtained and possible damage due to use of too low a ratio is avoided The reverse gear comprises a freely-mounted planet-carrier 15, Fig. 3, which can be slid axially along the driving shaft 11 to clutch a driven ring-gear 14 for direct-drive, or fixed casing-teeth 19 for reverse, and its shift-rail 43 may be controlled through solenoids, fluidpressure or mechanical means, by a separate lever B, Fig. 1, or by the same lever A, Fig. 5 (a), as that which controls the change-speed gear. In Fig. 1, the separate reverse lever B, controls forward, neutral and reverse through circuits 35, 67, 33, and also in its forward position F feeds current through a double lead 37, 38 to the change-speed switch-lever A, which moves in an H-gate 1, 2, 3, 4 for feeding the terminals El,... E4, of the change-speed magnetwindings in selected combinations. In its neutral or reverse positions N or R, the reverse-lever B cuts out the speed selector switch lever A and, in the reverse portion R, it also feeds the terminals E1, E3 establishing third speed. In the single-lever control, Fig. 5 (a), the gate of the selector-lever. A has a fifth channel in which it energizes the terminals E1, E3, Fig. 1, for third speed as before, and there are additional contacts 26, 21 at opposite ends of the crosschannel, by which the change-speed lever A also energizes forward or reverse solenoids 24 or 23 respectively acting on the planet-carrier shiftrail 43, Figs. 5 (a) and 3. Additional solenoids 60, 61 move the shift-rail 43 to neutral and are energized by a gate contact 27, feeding to either solenoid 60 or 61 through a throw-over switch 66 operated by the shift-rail 43 itself to ensure feed to the solenoid for the appropiate direction of movement. In Fig. 4, not shown, the reverse shift-rail 43 is operated by a double-acting hydraulic piston, loaded on each side by neutralizing springs.

Title: Improvements in stop mechanisms for fly frames
IPC: D01H13/16
Filed: 1947-02-26
Abstract: 637,520. Fly frame stopping mechanism. BLAN & CIE., and CARRETTE, M. Feb. 26, 1947, Nos. 5614 and 5615. Convention dates, April 23, 1946 and July 29, 1946. [Class 120 (ii)] In a stop mechanism for fly frames, a fluid stream is directed through a perforated plate so that when any broken sliver which is carried along in the fluid stream clogs the perforation in the plate a pressure variation is set up which is used to operate the stopping means for the frame. When a sliver 1 breaks, the end is sucked into an opening 4 and against a perforated piston 8 which moves to the left to tilt a mercury switch 13 to energise a solenoid 15 and remove a stop 17 from a weight- or spring- biased lever 19 to allow the same to move a rod 23 to the right and so shift the driving belt from the fast to the loose pulley. As the piston moves towards the end of its stroke to the left, Fig. 1, a port 35 is opened and the broken end separated by the operative is drawn away. The mechanism is " locked " temporarily in this position by a pivoted lever 31 which engages a projection 33 on the piston rod 9. After " piecing" by the operative, he pushes the rod 23 to the left, to restart the frame, and a cam 34 rocks the lever 31 to free the piston 8. In a modification, a mercury manometer, provided with the necessary terminals, replaces the mercury switch 13. In a further modification, the piston 8 is replaced by a pivotal flap carrying an arm which operates the switch 13. In a still further modification, the switch 13 is operated by a lever system from a bell jar partly immersed in liquid, the inside of the bell jar being connected to the suction conduit.

Title: Improvements in the manufacture and production of side-chain bearing polynuclear aromatic compounds or their sulphonic acids
IPC: C07C2/86
Filed: 1927-03-03
Abstract: 267,132. I. G. Farbenindustrie Akt.- Ges. March 3, 1926, [Convention date]. Alkylated and aralkylated cyclic compounds; sulphonic acids.-Polynuclear aromatic compounds are alkylated, aralkylated or cycloalkylated in the nucleus by treating them with acid sulphuric esters of alcohols having three or more carbon atoms in the molecule, with or without the use of condensing agents. If the operation is effected in the presence of a large quantity of sulphuric acid or at comparatively high temperatures, sulphonation takes place at the same time. In an example, n-butyl alcohol is treated with cblorsulphonic acid and the resulting ester is heated to 95 C. with naphthalene until the reaction product gives a clear solution in water; the sulphonic acid obtained is then converted into its sodium salt; other butyl, propyl, or amyl alcohols, cyclohexanol or its homologues may be err ployed instead of n-butyl alcohol. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the process to carbocyclic and heterocyclic compounds in general, including benzene and its homologues, such as toluene and xylene, anthracene and its homologues, phenols and naphthols, and pyridine and quinoline. In further examples, (1) isopropyl alcohol is converted into the acid sulphuric ester by means of chlorsulphonic acid and the product stirred with benzene for several days at 20 to 30 C.; the resulting propylated benzene is boiled with excess of strong caustic soda, steam-distilled and fractionated, and (2) benzene is mixed with the acid sulphuric ester from isopropyl alcohol and chlorsulphonic acid, the mixture is stirred for some hours, sulphuric acid is added, and the mixture warmed until the reaction product is soluble in water, the resulting sulphonic acid being then converted into its sodium salt. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,067,634. Bag-filling machines. BUHLER GEB. Feb. 11, 1966 [Feb. 19, 1965; July 2, 1965], No. 6164/66. Heading B8C.  A reciprocating plate 9, Fig. 1, which beats sacks 12 laterally during filling with bulk material, is resiliently mounted so that it adapts itself to the inclination of a sack during beating. In the embodiment illustrated, the plate 9 is secured to a shaft (8) by supports 34 {see also Figs. 2, 3, not shown), which are angularly adjustable about the shaft to alter the stationary inclination of the plate 9. The shaft 8 is vibrated by the action of a connecting rod 6, eccentrically mounted on a driving shaft 5, and links 11. The connections between the rod, links and shaft 8 are provided by resilient rubber bushings (10), 30 respectively, while the other ends of the links are attached to brackets 42 on base-plate 1 by similar rubber bushes 40. Thus the bushes take up the angular variations between the plate 9, links 11 and rod 6, thereby allowing the plate 9 to adjust its own inclination to that of the sack during beating. The base-plate 1 is weighted, e.g. by concrete, to damp the vibrations of the device, similarly vibration damping elements 44 are provided between base-plate and base frame 45. During beating, the sack 12 is suspended from a bell-type sack filling arrangement 14. In a second embodiment, Fig. 4 (not shown), the plate 9 is connected to the shaft 8 by support plates (60), mounted on the shaft 8 by additional bushes (57).  In a modification, resilient rods may be used in place of the links 11. In a third embodiment, Fig. 5 (not shown), a beater plate (19) is resiliently mounted on rods (17), through bearings (18), springs (20) providing the resilient mounting. In this case the vibratory motion is again obtained through the rod 6 eccentrically mounted on the shaft 5. Control means, e.g. timers, are provided on the motor driving the beating device, by means of which the beating time may be regulated, the control means stopping the motor at the end of the beating period.

Title: Improvements in or relating to alternating current relays
IPC: H01H53/10
Filed: 1947-03-06
Abstract: 622,171. Induction relays. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 6, 1947, No. 6368. Convention date, Jan. 15, 1946. [Class 38(v)] In a high-speed induction relay responsive, for example, to " current " and " voltage " coils round the centre and outer legs of an E-shaped magnet, the conducting member 12 which carries the contact 36 is of sheet-like form with limited motion and comparatively small area and is supported by means providing low inertia. In the form shown, the member 12 rests on two members 21, 22 each having fixed to it two rockers 26 which rest on bars 27. The curvature of the rockers is such that gravity tends to return the members 21, 22 to an upright position. A magnetic member 17 is arranged below the member 12. The arrangement is also such that when the current coil 9" is energized alone, the interaction of leakage fluxes produces a " decentering" force on the member 12. The reluctance of the magnetic core may be varied by screwed inserts 44, 45. In a modification, the member 12 is suspended by two blade springs, instead of being mounted on rockers.
