Abstract: 466,364. Inductances. SULLIVAN, Ltd., H. W., and GRIFFITHS, W. H. F. Jan. 30, 1936, No. 2824. [Class 38 (ii)] A coil former built from radial and longitudinal members having different coefficients of expansion has the members connected such that the resultant coefficient of expansion of the former at the mean winding diameter is equal to the coefficient of expansion of the coil conductor. Also the resultant coefficient of expansion may be adjusted to give the coil any desired temperature coefficient of inductance, providing a conductor is selected for the winding which has substantially the same linear coefficient of expansion as the former at the mean winding diameter. The former is built up of longitudinal members 6 having end lugs 10 attached at the points 11 to end members 5. the members 6 forming a support for the coil conductors 8. The longitudinal members have a larger coefficient of expansion than the end members 5 and, knowing the coefficients of expansion of the wire 8, the members 5 and 6 and the coil diameter, the distance x can be calculated. As shown in Fig. 1, the distance x may be varied around the circumference of the coil to compensate for material having different coefficients of expansion in different directions of grain. In a modification, a multi-layered winding is used in which case the distances are calculated on the mean winding diameter. Specification 326,190, [Class 37], is referred to.

Title: Improvements in or relating to clutches and clutch assemblies
IPC: F16D25/0638
Filed: 1953-02-04
Abstract: 725,571. Friction clutches. BORG-WARNER CORPORATION. Feb. 4, 1953 [Feb. 6, 1952], No. 3147/53. Class 80 (2). To prevent idle drag due to centrifugal pressure of residual oil in the pressurechamber C of a hydraulically-applied friction clutch 38, supplied through passages 42, 51, 67 by an input-driven pump P, the idle-speed pressure of which is insufficient to cause clutch engagement, the engaging piston 23 has a bleed hole 69, leading to a back space 70, the rear of which has an outwardly divergent opening X, defined by the inclined rear face 25a of the piston and the adjacent clutch disc 38, which latter is a conically-dished Belleville spring-plate with its raised inner periphery contacting the piston. Centrifugal idle pressure is thus free to drain at X, but normal engaging pressure distorts the Belleville clutch-disc over centre to close the escape X and cause build up of engaging pressure. Others of the clutch discs 38 splined to the outer input member 22 may also be Belleville spring plates flattened under engaging load, the complementary discs 37 splined to the inner output member 27 being flat. A central spring 36 assists the Belleville plates for clutch-release. Overriding mariual control is provided by a valve V which is a combined control and relief valve, the closure member 47 of which is turned manually through a cable 65 to either of two positions for exhausting at 54, 52 or shutting off exhaust respectively, from the pressure-passage 42. Excess pump-pressure moves the closure-member 47 axially against a spring 61 to exhaust the pressure-passage 42 at the same port 54. The clutch is used in an automatic transmission on a vehicle.

Title: Process for the manufacture of artificial tanning agents and products resulting therefrom
IPC: C14C3/20
Filed: 1939-01-30
Abstract: Artificial tanning agents are prepared by cold-sulphonating phenol or its homologues in the presence of fatty alcohols, or ester of fatty alcohols, saturated or unsaturated, and then condensing the sulphonation product thus obtained with formaldehyde, or with urea and formaldehyde in acid solution.  An alternative form of the invention comprises condensing the sulphonation product obtained as above with the condensation product of urea and formaldehyde in acid or alkaline solution, and finally partially neutralizing the products to a pH of 3.  The preferred proportion of sulphonated phenol to aldehyde is two molecules of sulphonated phenol, less than one molecule of urea and one to two molecules of formaldehyde.  The final neutralization may be carried out with sodium or potassium hydroxide, ammonia, or an organic salt of these bases, but preferably with a hydrate or oxide of a heavy metal such as chromium, manganese, aluminium or magnesium.  In examples: (1) Oleum is added to a mixture of phenol and lauric alcohol melted together and cooled to 40 DEG  C. The mixture is kept at room temperature for 24 hours and diluted with water, not allowing the temperature to rise.  An aqueous solution of formaldehyde is then added.  (2) To a sulphonated phenol prepared as in example (1) there is added an aqueous solution of urea followed by an aqueous solution of formaldehyde.  (3) As in example (2), but using a melt of ortho-cresol and cetylic alcohol instead of lauric alcohol and phenol.  (4) Oleum is added to a mixture of boric esters of cetylic alcohol and of oleic alcohol and xylenol.  After sulphonation as in example (1) the product is treated with aqueous formaldehyde.  (5) Xylenol is sulphonated as described in example (1) and to the sulphonation product so obtained there is added a condensation product of urea and formaldehyde, together with additional formaldehyde.  Specifications 305,013, [Class 2 (iii)], 388,475, 425,037 and 456,741 are referred to.
