Title: Improvements in or relating to the preparation of alpha-sulfoalkanoic acids
IPC: C07C309/17
Filed: 1960-09-16
Abstract: Alpha-sulphoalkanoic acids containing from 8 to 22 carbon atoms are prepared by adding less than the stoichiometric amount of a sulphonating agent to an alkanoic acid, holding the reaction mixture, adding a further portion or portions of sulphonating agent to complete the reaction, and cooling to precipitate the alpha-sulphoalkanoic acid.  The sulphonating agent may be sulphur trioxide in liquid or vapour form, the vapour being diluted with an inert dry gas.  The reaction may be performed in an inert diluent e.g. a halogenated hydrocarbon e.g. tetrachloroethylene, ethylene dichloride or carbon tetrachloride. The reaction temperature may be from room temperature to 212  DEG F.  After the final reaction a second inert diluent, which may be a hydrocarbon e.g. hexane or a petroleum ether, is added and the reaction mixture is cooled to precipitate the sulphoalkanoic acid.  In examples stearic acid, lauric acid and palmitic acid are sulphonated with sulphur trioxide, using tetrachlorethylene and ethylene dichloride as the first inert diluent and petroleum ether as the second inert diluent. Myristic acid and acids obtained from tallow, lard, palm oil, coconut oil, soybean oil and menhaden fish oil, also may be sulphonated.

Title: Motor bogie for rail vehicles
IPC: B61F5/22
Filed: 1961-09-06
Abstract: 969,919. Railway vehicle undercarriages. SCHWEIZERISCHE LOKOMOTIV - UND MASCHINENFABRIK. Sept. 6, 1961 [Sept. 8, 1960], No. 32050/61. Heading B7L. A motor driven bogie comprising a frame 3, Figs. 1 and 2, and axles 1, 2, supporting the frame 3 from axle box housings 5 through springs 4, is connected to the vehicle body 7 by two linkages either one of which transmits the tractive and braking forces according to the direction of movement, and linkage comprising a pair of rods 23, 24, pivotally connected together by a joint 25, Fig. 3, which permits relative movements of the sections in vertical planes only and which is guided transversely of the frame 3 by a guide surface 27, the rod 23 being pivoted to the bogie at 22 and pivoted to the vehicle body 7 at 28. A lost-motion connection is provided at the pivoted 28 so that the linkage can only transmit traction forces but not compression forces. The pivots 22 of the two linkages are carried by a connecting member 21 between the housings of electric motors 14 which drive the axles 1, 2 through gears 15. The vehicle body 7 is carried by a cross-member 8 mounted at each end on a rubber spring unit 12 on cradles carried by pivoted rocking bars 10 on the frame 3. The joint 25, Fig. 3, comprises a fork on the end of the rod 23 embracing the end of the rod 24 and the fork externally carries rollers 26 engaging the surface 27 carried by the bottom of the associated motor housing. Instead of a fork the end of the rod 23 may comprise a frame within which are mounted the rollers, the frame being pivoted to the forked end of the rod 24. The linkages assume the positions shown in Fig. 2 as the vehicle travels around a curve, but owing to the nearness of the pivots 22 to the bogie centre, there is only a small restoring torque on the bogie. Moreover, an upward force acts on the joint 25 to compensate the additional loading on the associated axle which occurs when the bogie accelerates.

Title: Reclining chair of the multiple position lounger type
IPC: A47C1/0355
Filed: 1963-08-14
Abstract: 976,447. Reclining chairs. A. LORENZ. Aug. 14, 1963 [Aug. 14, 1962], No. 32122/63. Heading A4J. A reclining chair which can be moved from an upright position to a tilted sitting position with no change in the angular relationship between the seat 22 and backrest 24, and to a fully reclined position with an increase in the angular relationship between the seat 22 and back-rest 24, has a leg-rest 26 mounted for movement to an elevated position during the first movement phase, and two independent linkages operative during the two movement phases. The first linkage includes an intermediate co-ordinating link 34 as a movable link which is pivotally mounted by further links 36, 42 on a support 32. The second linkage comprises a six-bar control linkage operable during the second movement phase with means for blocking the movement of the movable links of the first linkage at the end of the first movement phase such that the intermediate coordinating link 34 serves as a stationary link of the second linkage and effectively provides a stationary pivotal mount for the back-rest 24, during the second movement phase. The six-bar control linkage comprises the link 34, brackets 48, 52 secured to the seat and back-rest, respectively, a bell-crank lever 56 and connecting links 60, 66. When the chair is in the upright position and the occupant pushes rearwardly against the back-rest, a control link 98 pushes downwardly and operates a lazy tong linkage 28 and raises the leg-rest 26. This downward force tends to oppose upward movement of the seat 22 and therefore opposes the operation of the second linkage, thus the seat 22 and back-rest 24 move rearwardly under control of the first linkage until a notch 42a of the link 42 engages a stop 72 on the support 32. In this position the intermediate co-ordinating link 34 is stationary and further pressure upon the back-rest operates the six-bar control linkage which moves the chair into its fully reclined position, when a stop 103 mounted on the link 34 abuts an arm of the bell-crank lever 56. Alternatively the chair can be held in its fully reclined position by blocking any one of the six-bar control links or by blocking the back-rest against further reclining movement. A positive sequencing device 105, Fig. 4, may be incorporated to ensure proper order of operation of the linkages. This device 105 comprises a plate 106 which is pivoted to the seat bracket 48 and coupled to a leg-rest link 80 and has a double arced slot 114 to receive a pin 116 secured to the link 34. The pin 116 follows the path of the slot 114 and thus ensures the correct movement of the link 34.

Abstract: 643,684. Linear-dimension gauges; indicating-apparatus. BRYANT CHUCKING GRINDER CO. Dec. 8, 1947, No. 32357. Convention date, March 31, 1942. [Classes 106 (ii) and 106 (iv)] In a linear-dimension gauge combined with a dial indicator, the casing which holds the dial indicator is provided with means for vibrating it, so that the pointer and associated mechanism do not stick and the sensitivity thereof is increased. The form shown in Fig. 4 for gauging internal dimensions comprises a support 3 for a casing 4 and a slide 14 for a gauge feeler 15, slidably mounted on a base 1, and a second feeler 13 on an arm 8 which is pivoted by leaf springs 9, 10 to the base and adapted to actuate the stem 6 of a dial indicator 5 fitted in the casing 4. The casing 4 may contain a solenoid and armature vibrator which, when connected to an A.C. source, will vibrate the casing. As shown in Fig. 5, a small motor 30 is fitted within the indicator casing 40, and the armature 31 carries a cam 32 adapted to oscillate a spring 33 secured to the motor body, and so cause the casing 40 to be vibrated. The cam and spring, in another form, are replaced by an unbalanced weight on the armature. The indicator casing 50 in the form shown in Fig. 7 contains a fluid-operated piston 51, a slide valve 52, and the necessary inlet and exhaust passages, whereby, when fluid is supplied through a pipe 56, the piston is reciprocated. The vibrations set up in the casing for the dial indicator also serve to position the relative positions of the gauging feelers and the work-piece to be gauged. Specification 643,178 is referred to.

Abstract: 495,355. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 25, 1937, No. 32552. Convention date, Nov. 26, 1936. [Class 40 (iv)] A switching centre at which two subscribers' lines are adapted to be connected to a common exchange line comprises an individual relay for each subscriber connected between ground and different wires of the exchange line. Operation of a relay connects the corresponding subscriber's line to the exchange and opens the calling circuits of both subscribers. The subscribers have local battery sets and separate jacks at the exchange, and a call may be set up from one to the other. In the arrangement shown in Fig. 1, magneto calling current, say from subscriber A, operates calling indicator S1 at the exchange over a circuit from ground at the switching centre, subscriber's loop and wire La of the exchange line. Relays A1, B1 are sluggish and do not respond to calling current. The indicator on operating completes a circuit for relay A2 (shunted by a rectifier) in series with subscribers relay A1 which functions as stated above. Relay A2 disconnects the indicator and connects a resistance 9 to line Lb to balance relay A2. The operator responds and supervises the call, relays A2, A1 being held over a jack spring. The operator sets up a call to one of the subscribers by plugging the corresponding jack to operate relays A1, A2 or B1, B2, but when the other subscriber is the calling party she should remove the answering plug to prevent ringing current reaching that subscriber and shunting of the ringing circuit by a telephone set. In the modification shown in Fig. 2, providing improved line balance, the relays A1, B1 are associated with coils 21, 25 and rectifiers 20 .. 24 and the balancing resistance at the main exchange is replaced by a coil 26 connected to positive battery. On a call from A, relays A1 and A2 are held over ground, rectifier 22, relays A1, A2 to negative battery and this circuit is balanced by one over ground, coil 25, rectifier 23, coil 26 to positive battery, the battery having a mid-point ground.
