Title: Crystalline anhydrous citric acid and method of making same
IPC: C07C51/43
Filed: 1931-06-19
Abstract: Oversaturation is effected in a saturated aqueous solution of citric acid at a temperature between 41 and 100 DEG  C., so that the excess acid is crystallized out in the anhydrous state. Oversaturation may be effected by adding solid, hydrated citric acid to a solution saturated and maintained at, for example, 55 DEG  C., or by continued evaporation at the boiling-point under an absolute pressure of more than 1\ba1/4\be inches of mercury, or by concentration in a similar way to about 42 DEG  B<\>ae., and then heating under atmospheric pressure to 75 or 80 DEG  C., after which the solution is allowed to cool in a crystallization pan to a temperature not below 41 DEG C.ALSO:Anhydrous citric acid is produced by effecting oversaturation in a saturated aqueous solution of citric acid at a temperature between 41 DEG  and 100 DEG  C.

Title: Electrical connector
Inventor: BROSKE WILLIAM FRANKLIN
IPC: H01R11/11
Filed: 1953-06-29
Abstract: 736,178. Cable and wire terminals. AIRCRAFT-MARINE PRODUCTS, Inc. June 29,1953, No. 17945/53. Class 38 (1). In the formation of a terminal connector comprising a ferrule 26, Fig. 2, and a tongue 28, a sheet of metal 20, Fig. 1, from which the connector is blanked and bent up is first laminated with a sheet 22 of tough insulating plastic so that the finished ferrule and tongue are provided on one side with insulation. Fig. 3 shows a modification wherein the insulating sheet 22a extends only over the ferrule-forming portion of the metal sheet 20a and in the modification thereof in Fig. 5, the plastic sheet 22b extends outwardly beyond the ferruleforming portion to form a sleeve round the insulation of a wire crimped in the ferrule. In Fig. 7 the plastic 22c extends over the edges of the metal 20c so that the butt joint formed in the ferrule is sealed. Fig. 8 shows a modification of this construction wherein points 24d at the edges of the ferrule-forming portion are left bare of insulation so that they may be driven into a wire. According to a further construction, a strip of connector blanks is stamped out with the blanks arranged side-by-side, and is subsequently laminated with a sheet of plastic which is then stamped to leave an extension beyond the ferrule-forming portion. The plastic is also drawn over the edges of the metal as shown in Fig. 15 and forms a lip 39 round a hole for a binding-post or screw in the tongue portion, which lip, through its resilience, acts against a binding-post nut or screw and prevents accidental loosening. In Fig. 16 a metal strip 20g has insulation 22g on both sides, the connectors in this case being bent up as shown in Fig. 17 so that the cut edges can contact a binding-post nut or screw-head. Specification 613,013 is referred to.

The discharge nozzle 1 of a gas turbine propulsion unit on aircraft is extended rearwardly by a sleeve 2 which acts as an ejector for mixing ambient air with the propulsive jet, the sleeve 2 being surrounded by gas deflecting guide vanes 3. Blades 4, 5, 6 and 7, faired in cross-section, are mounted for pivoting movement about their respective axes in T-shape fittings 12 under the control of linkwork and a screw jack (not shown). The fittings 12 are mounted on axes tangential of the jet pipe for fore-and-aft pivoting movement under the control of racks 10 which engage toothed sectors formed on fittings 12, the racks being operated also by a screw jack. In normal thrust conditions the blades 4-7 are positioned clear of the jet in the positions shown in full line in the upper half of the figures, whereas to deflect the jet the jack controlling the rack 10 is operated to swing the blades forwardly and inwardly to the chain-dotted positions with their chords parallel with the jet stream. The other jack is then operated to swing the blades about their respective axes until they occupy the transverse positions shown in full line in the lower half of the figures. Specifications 751,316 and 751,317 are referred to.

Title: Improvements in or relating to Thrust Bearings and Brakes for Driving and Reversing Gearing.
Inventor: WILKINSON ROBERT HUDSON
IPC: F16C19/10
Filed: 1918-11-02
Abstract: 134,601. Wilkinson, R. H. Nov. 2, 1918. Stopping-arrangements.-A thrust ball bearing for worm or other shafts is arranged to take end thrust in one direction of rotation, whereas, if the direction of the thrust or of rotation changes, the ball bearing becomes inoperative and a friction bearing acting as a brake comes into action. Balls e, Fig. 1, are placed between a thrust collar b on the shaft and two intermediate collars f mounted loosely on the shaft. The collars f bear against thrust washers g supported by the casing h and by an adjustable block i held against rotation by pins k. Spring-pressed pawls n, n<1> carried by the collar b and bv the casing, engage ratchet teeth m on the collars f, allowing' each collar to rotate in one direction onlv. Normally, end thrust on the shaft a is taken by the ball bearing against the corresponding co'lar f, which remains stationary, but, if the direction of rotation changes, the collar is constrained by the pawl n to move with the shaft and the thrust comes on the washers g which act as a brake. As soon as the direction of the thrust also changes, the corresponding ball bearing comes into play. The device is intended to ensure rapid stopping and reversing of a driven member. Fig. 4 shows a modification in which the pawls n carried by the collar b are replaced by an epicyclic bevel pinion r engaging both the collars f, With this arrangement, one collar is held stationary by the pawl n<1> and the other rotates at twice the speed of the shaft, and the braking effect is therefore increased. The washers g are divided into fixed and rotating groups in the manner cf a plate clutch. In another modification, the balls c and washer g are interchanged, the pawls n are dispensed with and the pawls n<1>, besides acting automatically, can be actuated by hand-levers to apply the brake at will.

The conductors may be circular or oval and each is preferably made up of a number of fine wires. The whole is enclosed in a tough rubber sheath 6, which may have a constant outer diameter or the diameter may be different at the short lay end, and the two ends may be distinguished by markings.
