Title: Means for fully automatic weighing
IPC: G01G1/28
Filed: 1959-06-29
Abstract: 906,061. Weighing apparatus. MEOPTA PRAHA NARODNI PODNIK. June 29, 1959 [June 28, 1958; May 26, 1959], No. 22160/59. Class 143. [Also in Group XXIV] The weights successively applied to the counterweight side, or removed from the load side, of a balance to determine the weight of the load are automatically applied or removed in steps always smaller than the difference between the weight of the load and the sum of the weights already applied (or removed) by an apparatus comprising means for placing weights of a given order of magnitude in steps until the beam is underbalanced by an amount, dependent on the beam's sensitivity, representative of a difference between the weight of the load and the weights so far placed of less than one such step, and means for automatically increasing the beam's sensitivity at this point in the weighing and subsequently placing weights of a correspondingly smaller order of magnitude. The apparatus as shown is operated by the clockwise rotation of a shaft 14 carrying a disc 13 from the face of which projects a pin 12 which enters the right-hand limb of a U-shaped slot 11 in a rocking lever 10 to effect anticlockwise rotation of a cam-shaft 29 through a pawl lever 40. A plurality of weight-placing levers 25 for weights of the largest order of magnitude are operated in succession by cams 20 carried by this cam-shaft until the balance beam (not shown) achieves the required degree of underbalance. This is detected by means capable of operating a pawl or the like to raise a rod 47 and thus render the pawl at the end of lever 40 ineffective. The means for raising rod 47 also effects the rotation of a ratchetwheel (not shown) by one step to operate a lever which removes one of a set of weights loading the beam fulcrum, thus increasing the sensitivity of the balance At the same time cam 48 is rotated into a position in which the pawl lever 40 shown is retained in its upper position while another cam (not shown) on the same shaft as cam 48 is moved, from a position in which it holds up the pawl lever 40 of weight placing mechanism for a set of smaller weights, into the position corresponding to that shown for the original set of weights. The rod 47, which has temporarily raised not only the pawl lever 40 shown, but also these corresponding to the smaller orders of magnitude of applied weights, is then lowered so that placing of the next smaller set of weights can begin. This process is repeated until the load's weight is known to within a fraction of a unit of the smallest order of weight used. The beam is unloaded by the removal of all applied weights in the reverse order effected by reverse rotation of shaft 14.

Title: Locking differential
Inventor: THORNTON RAY FREDERICK
Filed: 1958-07-10
Abstract: 878,077. Differential gear. THORNTON AXLE Inc. July 10, 1958, No. 22208/58. Class 80 (2). A planetary differential gear is rendered selflocking by clutch plates 52, 54, 56, 58 loosely splined to output side wheels 32, 66, and clutch plates 76, 80 splined to an input casing 10. Pressure rings 84, 128 are splined to the casing 10 and are formed with cam surfaces 124, 126 co-operating with complementary surfaces of balance bars 114 mounted on spider trunnions 100 carrying planet pinions 94. In operation, as the casing 10 rotates the balance bars lag and act on the forward or rearward cam surfaces of the pressure rings 84, 128, moving them apart, which engages the clutch plates and so locks the differential gear. During a turn, the accelerating tendency of the outside wheel causes the spider trunnions 100 and balance bars 114 to advance relatively to the casing 10 to their neutral position, thus releasing the clutch pressure for normal differential action. In a modification each balance bar is mounted on a circular section end of a trunnion and has a tendency to rotate on the trunnion so as to act on diagonally opposite cam surfaces of the pressure rings which are thus moved apart.

Title: Improvements relating to chromium-containing monoazo dyestuffs and their use
Inventor: BEFFA FABIO
IPC: C09B45/16
Filed: 1959-07-02
Abstract: The invention comprises dyes of formula <FORM:0887594/IV (c)/1> where A-N=N-B is the residue of an o,o-dihydroxy monoazo dye which has no groups which dissociate acid in water but contains substituents that increase the water-solubility in such a way that the dye, in the form of the above chromium complex, has the characteristics of a textile dye, X is an alkyl radical with at least 2 C atoms and Y is an alkyl radical, X and Y together having at most 5 carbon atoms.  The dyes may be made by treating a mixture of appropriate dyes with a chroming agent or from appropriate 1,1-chromium complexes by adding the other dye. Indicated as water-solubility increasing substituents are: sulphonamide groups derived from primary or secondary aliphatic amines with at most 8 carbon atoms, ammonia or a cyclo- or ar-aliphatic amide, an alkylsulphonyl group of 1-6 atoms, especially the methylsulphonyl group, amino groups acylated with organic sulphonic or carboxylic acids, and a carbonic acid monoester radical. Advantageously both metal-free dyes are of the benzene-azo-naphthalene series, in particular A-N=N-B should be a 2-phenol1,11 - azo - 21 - naphthol containing a sulphonyl group, especially a 5-methylsulphonyl substituent, and an 81-acylamino group, expecially an acyl residue derived from an aliphatic carboxylic acid.  Preferably the acyl residue is acetyl but it may also be a carbo-(b -alkoxy)-alkoxy radical. Symmetrical dyes are preferred.  The dyes colour natural and synthetic polypeptides, e.g. wool and silk, from neutral or weakly acid baths, in grey to brown shades.  The dyes also colour lacquers, varnishes and plastic materials.  In examples, which illustrate the preparation of the dyes and their use in colouring processes, representative of dyes used corresponding to A-N=N-B are: 2 - aminophenol - 4 - ethyl sulphone --> 7 - hydroxynaphthyl - (1) - carbamic acid methyl or ethyl glycol esters, 2-aminophenol-4-butyl sulphone --> 7-hydroxy-naphthyl-(1)-carbamic acid methyl glycol ester and 2-amino-phenol-4-methyl sulphone --> 1-acetylamino-7-naphthol. Reference has been directed by the Comptroller to Specifications 637,404, 730,036 and 758,016.

Abstract: 1439071 Heat treating bearing steel TORRINGTON CO 15 May 1973 [18 May 1972] 23064/73 Heading C7A A body of A1S1 52100 steel is austenitized for a time sufficient to dissolve the carbides initially present and is then cooled rapidly to yield a fine pearlite structure, after which it is re-heated into the austenitizing range to transform the ferrite of the pearlite to austenite and to convert the pearlitic carbide into very small undissolved excess carbides, the time and temperature being such that growth of the carbides is prevented. Finally the steel is quenched and tempered to a hardness suitable for use in bearings. The initial heating may be to 2100F, followed by quenching into salt or lead at 900-1333F to produce pearlite and subsequent hardening from 1500F. The steel may be allowed to cool, and possibly also cold worked, between the pearlite-formation and hardening steps, while rapid heating in the latter step may be effected in two stages using a first bath which pre-heats the steel to just below A 1,3  and a second bath which finally heats it to the desired temperature.

Abstract: 673,781. Photo-electric control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 21, 1950 [Oct. 20, 1949], No. 23144/50. Drawings to Specification. Class 40 (iii). [Also in Group XXXV] An oscillatory photo-electric scanner for the lateral regulation of a travelling sheet comprises a source of a light beam, a device having an oscillating reflector disposed to reflect the beam on to the sheet surface, a photo-electric tube so located as to be illuminated by light reflected from the surface due to the beam and a lens in the path of the beam between the source and the sheet surface having beamcontracting properties substantially only in the direction traverse to that of the beams oscilatory movement. In the embodiment described the scanning arrangement and automatic control system moving the sheet laterally to correct for any detected errors in alignment are similar to those described in Specification 668,205. In accordance with the present invention a cylindrical lens is placed between the oscillating reflector and the sheet with the lens axis transverse to the direction of travel of the sheet. This has a negligible effect in the direction of scan but narrows the width of the beam in the direction of motion and so enables the apparatus to function effectively if the guide line marked on the sheet is skewed and not perpendicular to the direction of scan.
