Title: Improvements in stiffening for collars and other articles of personal wear
IPC: A41B3/10
Filed: 1936-11-02
Abstract: 490,041. Stiffening wearing apparel. TENNANT, W. J. (Elsbach. & Co. Akt.-Ges., J.) Nov. 2, 1936, No. 29794. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 3, 1938.] [Class 141] [Also in Group VIII] A collar, shirt-cuff, shirt-front or other article of clothing comprises, as a stiffener, an insert or backing of textile fabric coated with cellulose derivative, the coating having therein fine fissures to permit penetration of moisture. The insert or backing may be made by passing textile fabric over a heated roller and simultaneously applying thereto, e.g. by brushing or spraying, a solution of cellulose acetate. The solvent rapidly evaporates leaving fine fissures in the cellulose acetate coating. The insert or backing may be attached to the collar &c. by sewing or heat treatment. The Figure shows a collar comprising an insert 3 and a backing 3<1>. Reference has been directed by the Comptroller to Specifications 374,983, 460,232, and 460,523, [all in Group VIII].

Title: Esters of diboronic acids
Inventor: BAMFORD WILLIAM RANDALL
IPC: G21F1/10
Filed: 1960-09-01
Abstract: Fibre-forming resins are made by heating bis (1:1:1-trimethylolpropane) p-phenylenediboronate with a di-isocyanate such as 4,41-di-isocyanatodiphenylmethane or 2,4-di-isocyanatotoluene in xylene under reflux conditions. Polymeric resins are obtained when bis (triethanolamine) tetramethylenediboronate is heated with a di-isocyanate or dimethyl terephthalate in the presence of zinc acetate and antimony trioxide.  A brittle thermosetting resin is obtained by heating bis (tris-(hydroxymethyl) phosphine oxide)-p-phenylenediboronate with urea.  Specification 864,473 is referred to.ALSO:The invention comprises compounds having the general formula <FORM:0913385/IV (b)/1> where R is a hydrogen atom, a methyl group or an ethyl group, R1 is a polymethylene group having from 4 to 10 carbon atoms, a p-phenylene group or an alkyl substituted p-phenylene group and Z is selected from divalent groups having one of the formulae <FORM:0913385/IV (b)/2> and <FORM:0913385/IV (b)/3> when R is a hydrogen atom and is <FORM:0913385/IV (b)/4> when R is a methyl or ethyl group, R2 being an alkyl or aryl group or an alkyl or aryl group having a halogen or an alkoxy or an alkenyloxy substituent.  The novel compounds may be made by heating a diboronic acid under reflux conditions with a trihydroxy compound of the formula Z(CRHOH)2 in a hydrocarbon solvent, the water being removed by azeotropic distillation. Alternatively, an ester, such as the tetrabutyl ester, of a diboronic acid is heated with the trihydroxy compound and the alcohol, e.g. butanol, removed by distillation.  In a further method, the acid and trihydroxy compound are heated in an alcohol and the product is crystallised from the solution.  Examples describe the preparation of bis(1 : 1 : 1 - trimethylolpropane)p phenylenediboronate, bis(triethanolamine)tetramethylenediboronate, bis(triethanolamine)p - phenylenediboronate, bis(1 : 1 : 1 - trimethylolethane)pphenylenediboronate, bis(tri-2-propanolamine) tetramethylenediboronate, bis(tris(hydroxymethyl)phosphine oxide)p - phenylenediboronate, bis(1 : 1 : 1 - trimethylol-2-chloroethane)-pphenylenediboronate, bis(allyloxymethyltrimethylolmethane)p-phenylenediboronate, and bis (triethanolamine) decamethylenediboronate.

[Class 52 (v).] Relates to apparatus for displaying garments of the kind in which a rack or frame is mounted on an upright rotatable shaft c carried by a. carriage B moving into and out of the showcase, the shaft being locked, except when withdrawn from the show-case, by the engagement of spring-controlled bolts with a notched disc carried by the shaft. According to the invention, the notched disc D is secured to the base of the shaft and the sliding bolt E is normally pressed into engagement with the notches d by a gravity-weighted or spring-actuated lever F, the unlocking -of the shaft being effected by the engagement and consequential displacement of the bolt with some fixed abutment- In the form shown, the carriage B is mounted on rollers b which engage in the side channels of a frame A, and is provided with horizontal rollers b<1> which engage with the flanges of the channels to minimize friction. The bolt E is fitted to the underside of the carriage and is formed with an extension e which is adapted to engage with an abutment f when the carriage is withdrawn from the show-case. By the engagement of the extension e with this abutment, the bolt is moved forwardly against the action of the weighted lever F and is thereby released from its locking engagement with the shaft. Additional known means may be provided to prevent the carriage being moved into the show-case when the rack is not in the correct angular position.

Title: An improved apparatus for the measurement of the power factor of electric alternating current circuits, more especially designed for remote measuring purposes

Filed: 1938-10-22
Abstract: 507,287. Power-factor measurements. LANDIS & GYR AKT.-GES. Oct. 22, 1938, No. 30624. Convention date, Oct. 22, 1937. [Class 37] A power-factor meter comprises a Ferraris meter 10 having one driving winding 11 supplied from the secondary voltage of a phase regulator 9 operated by a phase-controlling apparatus 1, the other driving winding 12 and the brake winding 13 being connected across the supply mains R, T. The phase-controlling apparatus 1 comprises a wattmeter having two measuring systems 2, 2<SP>1</SP> of which the current coils'3, 3<SP>1</SP> are connected in the phase conductors R, T of the polyphase network R, S, T and the voltage coils 7, 7<SP>1</SP> are connected to the secondary winding 8 of the phase regulator 9. The movable primary winding 16 of the phase regulator 9 is coupled through reduction gearing 17 with the rotor 18 of an auxiliary motor 19 having two field windings 20, 21 connected to fixed contacts 23, 24 and a movable contact 22 actuated by the wattmeter 1. At a particular value of the power-factor the contact 22 is stationary in its mid position and the motor 19 is not energized, so that the primary winding 16 remains stationary. The rotor 26 of the meter 10 then turns at a velocity proportional to the sine of the phase displacement, when the driving system is so adjusted that it is stationary at unity power' factor. Change of power factor causes the wattmeter 1 to move the contact 22 to engage one of the contacts 23, 24 so that the corresponding winding 20 or 21 is energized. The primary winding 16 is thereupon turned until the difference of phase between the driving fields of the wattmeter 1 is again neutralized and the contact 22 is returned to its mid-Position. The voltage driving field produced by the driving winding 11 of the meter 10 is then altered in phase by the same amount as the voltage driving field of the wattmeter 1, and the speed is correspondingly altered. A variable resistance 31 in series with the winding 11 enables the phase relation between the two voltage fluxes of the meter 10 to be adjusted so that at any definite power factor any predetermined speed of rotation may be selected. The rotor 26 may transmit impulses through brushes 15 for remote measurement. In a moditication the auxiliary motor 19 and the contacts 22, 23, 24 are omitted and the phase controlling apparatus 1 is directly coupled with the phase regulator 9.
