Title: Improvements relating to gripping devices for belts, straps and the like, for example aircraft seat safety belts
Inventor: BARRETT HUBERT ARTHUR
IPC: B64D25/06
Filed: 1953-08-28
Abstract: 730,152. Friction grip fastenings. SIEBE, GORMAN & CO., Ltd. Aug. 28, 1953, No. 23897/53. Class 44. In a gripping device for belts, straps and the like (hereafter called belts) e.g. aircraft seat safety belts, the belt b is gripped between a manually operated rotary cam 13 and a surface 8 of a wedge 7, the wedge 7 having freedom for a limited guided movement relatively to the body portion 1 of the device in the direction of length of the belt against a yielding control 9 which tends always to return it to normal position ; the cam is disposed with its axis of rotation parallel and transverse to the wedging surface 8 and the arrangement is such that movement of the wedging surface 8 under pull from the gripped belt and/or thrust from the cam during movement of the latter to the belt gripping position, transmitted through the gripped belt, operates to tighten the grip on the belt and further that under the wedging action the cam is self retaining in the belt gripping position until deliverately removed therefrom by hand to release the belt. The wedge is guided in its movement by pins 6. The cam 13 is pivotally mounted on a pin 20 and its shape causes it to remain in the belt gripping position (shown at A in Fig. 2) ; it is also provided with detent means to retain it in two further positions, the first of these is in the non-gripping position shown in full lines in Fig. 2 and the second is shown in chain lines at B and is the position at which gripping just commences. The detent means consists of a spring urged slidable sleeve 21 inside the cam 13 and surrounding its pivot pin and which is caused to rotate with the cam 13 by a grub-screw 28 arranged in a slot 29. The end of this sleeve is shaped as a cam and engages a cam 22 which also surrounds the pin 14 and which is secured to the body portion 1 of the device.

Filed: 1946-08-13
Abstract: Heterocyclic compounds of the general formula <FORM:0615006/IV(b)/1> where R represents an aralkyl, aryl or heterocyclic group, which may contain other substituents and M represents a polymethylene group containing 2, 3 or 4 methylene groups, are produced by heating an N-substituted amidine of the general formula RC(=NR1).NR2R3 where R1 represents an alkyl or aryl group and R2 and R3 each represent a hydrogen atom or an alkyl or aryl group, with an amino alcohol of the general formula NH2MOH in the presence of sufficient acid to form the normal salt of the amidine.  The heterocyclic compound may be formed either as the free base or as the salt, depending on the relative basicities of the bases present. Conveniently, the reaction takes place in the presence of excess of the amino alcohol, in which case the free base of the product is obtained.  In examples: (1) N-phenyl-p-methylsulphonylbenzamidine benzene sulphonate is heated with ethanolamine to give 2 - (p - methylsulphonylphenyl) - oxazoline; (2) N-phenyl nonatramidine benzene sulphonate is heated with ethanolamine and the product is treated with picric acid to be isolated as 2-(31 : 41-dimethoxyphenyl)-oxazoline picrate; (3) N : N : N1-trimethylbenzamidine is heated with ethanolamine toluene-p-sulphonate and the product is treated with lithium picrate to give 2-phenyl-oxazoline picrate; (4) N-cyclohexylphenylacetamidine hydrochloride and ethanolamine are treated as in (2) to give 2-benzyloxazoline picrate; (5) N-ethyl-p-methylsulphonyl - benzamidine toluene - p - sulphonate is heated with 2-methyl-2-aminopropanol to give 2 - p - methylsulphonylphenyl - 4 : 4 - dimethyl - oxazoline; and (6) N - phenyl - p - methylsul - phonylbenzamidine hydrochloride is heated with 3-amino-propanol to give 2-p-methylsulphonylphenyl-D 2-dihydro-1 : 3-oxazine.
