Title: Improvements in or relating to the resolution of isomeric mixtures of 1-p-nitrophenyl-2-aminopropane-1,3-diol
Inventor: FEITELSON BRUCE NORMAN
Filed: 1951-05-10
Abstract: The D- and L-threo-isomers of 1-p-nitrophenyl - 2 - aminopropane - 1,3 - diol are separated into their optically active D-(-)- and L-(+)-isomers by reacting mixtures of the said amino-diols with L-(+)-glutamic acid, separating the resulting acid addition salts of the D-and L-isomers by fractional crystallization from an aqueous or anhydrous organic solvent, and separately neutralizing the acid addition salts of the separated D- and L-isomers to obtain the corresponding separate D- and L-optical isomers of the free base of the amino diol.  Aliphatic alcohols of not more than 5 carbon atoms are suitable solvents. Ammonium hydroxide and dilute aqueous sodium or potassium hydroxide are specified for neutralisation.  In three examples a racemic mixture of the DL-threo-amino-diol is resolved using ethanol or industrial methylated spirit as solvent the neutralisation being effected to pH 9 to 10 with dilute ammonium hydroxide.  Specification 652,275 is referred to.

Title: Improvements in friction clutches
IPC: F16D43/10
Filed: 1926-07-27
Abstract: 276,406. Benn, H. H. July 27, 1926. Alternating-current motors; driving-arrangements.-In centrifugal friction clutches with axially-moving members d, e and pivoted spring- retracted actuating-masses f, for use with shortcircuited armature motors &c., the masses lie with their mass-centres near the plane containing their pivots f<1>. until, at a predetermined speed, they swing out to exert maximum effort on the clutch members, the spring effect being simultaneously reduced. Springs m, guided by stems m<2>, hold the masses f in the inactive position shown, but at the predetermined speed are overcome, allowing rapid movement of the masses, so that when their noses g contact with the presser-plate c<2>, the mass-centres are at their greatest distance from the plane of the pivots f<1>, while the stems m<2> are almost in line with the pivots. The critical speed can be adjusted by changing the springs m, and the clutching-force varied by screwing the housing c<3>, carrying the pivots f<1>, on the hub of the driving-shaft member c. The masses may be arranged, singly or in groups, with varying strengths of springs or varying distances of their mass-centres from the plane of the pivots, or both. The pivots may alternatively be disposed in different planes. For example, to avoid electrical impulses in starting up, say, a 6 H.P. short-circuit motor by changing from star to mesh connections, one group of three masses may be arranged to function at a speed just below that. when developing 2 H.P. on " star," and the remaining group of these to function only after the change to " mesh " has been effected.

Making metal fabrics.-The machine described in the parent Specification for making chain-mesh fabrics of small size, is provided with means for tilting each ring as made from the horizontal to a vertical position and moving it laterally in order that it may be engaged by the supporting helix 2, Fig. 2. The tilter consists of a pin 9 which has a forked or shouldered end to engage the ring 8 and is carried by a lever 11 which with its pin 9 is raised to a limited extent to engage the ring by a cam 16 acting through levers 14, 12.

The ring 8 is then tilted into the vertical position by the cam 16 to engage the receiving helix 2. When a row of rings is completed the levers 13 are rocked by means, which do not form part of the invention, to bring the lever 11 and its pin 9 on the other side of the fabric into effective operation on the next row of rings.

(Class 93] [Also in Group XL] A uniform layer of binder is applied to the surface to which a luminescent material is to be attached, by coating with a binder and causing a gaseous current to pass over the surface and expel the excess binder. A current of dry filtered air, which may be warmed, is directed tangentially towards the surface. The gas supply may be at a pressure of 1-5kg. cm<2>. When the binder consists of a mixture of two liquids, one of the liquids is volatile and is vaporized, Tube and incandescent lamps are held vertically during the application of the gaseous current, and long thin tubes may be employed to introduce the gas and cause it to flow out towards the opening. Several moving pipes may be used, The method may be used in conjunction with other methods of applying binders.

Title: Improvements in automatic parking brakes for motor and other vehicles
IPC: B60T7/12
Filed: 1954-04-20
Abstract: 759,209. Parking-brake controls. CARVALHO, R. P. T. R. DE. April 19, 1955 [April 20, 1954], No. 11283/54. Class 103 (1). [Also in Group XXXI] In a normally spring-applied parking brake for motor vehicles of the type in which the spring device may be released automatically by the depression of the driver's seat by the occupant's weight whereby when the occupant leaves the seat the brake is automatically applied, means operated by the pressure of the back of the occupant of the seat are provided for holding the brake in the released position. In the embodiment illustrated, the brake mechanism of the parking brake of a motor vehicle is coupled to a brake lever 1 pivoted intermediate its ends on a frame 2 on the underside of the driver's seat. Pivoted on frame 2 to the rear of the brake lever 1 is a lever 3, pivotally connected to brake lever 1 by link 4, and provided with a ratchet toothed sector 9 with which is associated a slidable catch member 10 which may be held into or out of engagement with the sector 9 by actuation of the catch-operating lever 11 pivoted to the frame member 6 at the rear of the seat. Fig. 2 illustrates the brake released position of the apparatus when seat lever 7 is depressed by the occupant's weight thus effecting pivoting of the toggle link mechanism against the action of spring 5 to release the brake. Should the weight of the driver be momentarily taken from the seat lever 7, due to uneven road surfaces, the pressure of the driver on the back of the seat 12 will engage the slidable catch member 10 with the ratchet toothed sector 9 and prevent the brake being applied. When the driver leaves the seat completely, the brake mechanism is applied by the spring 5 as shown in Fig. 1. If the vehicle is to be left unattended, a latch bar 14, pivotally mounted on the frame 2 in front of brake lever 1, is depressed against spring action 15 and the bar 14 bears on the brake lever 1 above its pivotal axis thus forming a stop holding the brake lever in its " on " position shown in Fig. 1. A keyoperated lock is provided to secure the latch bar 14 in the locking position to prevent unauthorized use.
