Abstract: 161,968. Schiffmacher, C. E. E. April 20, 1920, [Convention date]. Hubs.-In a fastening applicable to the fixing of spare wheels, a sliding plug with two stepped annular recesses, cooperates with balls to lock or release the device in relation to a fixed member. Fig. 10 shows the device applied to secure a wheel on an axle-tree 130. If the cap 28 is unscrewed and removed, the plug 19 can be depressed against a spring 27 and the balls 6 can leave the recess 14 in the axle-tree to enter the deeper recess 21 in the plug, allowing the wheel to be removed from the axle-tree. In putting the wheel on, the plug is held in its pushed-in position by two bolts 18, leaving both hands free to manipulate the wheel. When the wheel is in position on the axle-tree, the bolts 18 are turned, the plug shoots upwards, bringing the balls into the recesses 22 and 14. When the cap 28 is screwed on, the plug is secured against depression and the wheel is locked to the axle-tree. The plug is prevented from rotation when the cap is being screwed on by suitable feathers and featherways.

IPC: A43D35/00
Filed: 1933-04-20
Abstract: 399,740. Thermal switches; control of A.C. motors ; refrigerating. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. April 20, 1933, No. 11524. Convention date, April 20, 1932. [Classes 38 (iii) and 38 (v).] A relay or switch for controlling temperature or other conditions comprises a wave-shaped bimetallic strip having at least two half-waves 7, 8 controlled by separate heating coils 22, 18, the strip being clamped at the points where the curvature changes as shown. In the form shown and with the parts in the position shown, a circuit is prepared at 19 through the heating coil 18, so that when change in temperature of a refrigerator or pressure of its compressor causes a strip 14 to engage a contact 17, the circuit is completed and the strip 7, 8 snaps into the dotted-line position, breaking at 21 a circuit to the motor 1 of the refrigerator, breaking at 19 the heating circuit 18, and preparing at 20 the circuit of the heating coil 22. The latter circuit is completed when the temperature or pressure causes the strip 14 to engage the contact 23. The strip 7, 8 then snaps back. The contacts co-operating at 19, 20 with the bimetallic strip are resilient so to remain in contact with the strip till the snap occurs. The stop 7, 8 is also adapted, by means of a rod 24, to actuate a second bimetallic strip 25 to prepare at 26 a starting circuit for the motor 1 including a condenser 28, this circuit being completed when the strip 7, 8 moves back into its full-line position. The condenser 28 is then in parallel with a condenser 4 so that the motor starts with a powerful torque. A heating circuit 29 for the strip 25 is simultaneously closed at 27 which causes the strip 25 to move back to its full-line position after an interval and break both the heating circuit 29 and the starting circuit 28. In a modification, the device is adapted for control-by a reversing motor by arranging an additional contact to be engaged by the strip 7 in its dotted position.

Title: Process for the manufacture of benzene and of alkyl benzenes
IPC: C07C15/04
Filed: 1953-04-27
Abstract: Benzene and its alkyl derivatives are obtained by a process comprising the conversion of straight chain olefins of formula CnH2n, in which n may be 2 to 6, either singly or in admixture, by the process of Specification 713,081 or of Specification 742,642, into higher olefines having at least 6 carbon atoms in a straight chain and the subsequent aromatization of the higher olefins so obtained by dehydrogenation and cyclisation in known manner.  For example, butene-1 and butene-2 may be dimerized by heating at 180-250 DEG  C. in the presence of an alkylaminium compound or a similar organo-metallic compound according to the process of Specification 742,642, to yield mainly 2-ethylhexene-1 which on cyclization gives a mixture of o-xylene, p-xylene and ethyl benzene.  Similarly a mixture of 3-methylbutene-1 and propylene yields a mixture of p-xylene and o-xylene.  In the examples: (a) butene-1 is mixed with triethylaluminium and heated under pressure to give butene dimer which is heated in the presence of a chromic oxide catalyst to give p-xylene, o-xylene and ethyl benzene; (b) a mixture of 3-methylbutene-1 and propylene is treated as in (a) to give a mixture of p-xylene and o-xylene; (c) a mixture of butene-1 and propylene is treated as in (a) to give toluene and the same products from the aromatization of the butene dimer as in (a); (d) ethylene is heated with triethylaluminium to give butene, hexene and octene which on aromatization give p-xylene, o-xylene, ethylbenzene and benzene; and (e) a mixture of propylene and pentene-1 is heated with tripropylaluminium to give among other products a co-dimer of propylene and n-pentene which on aromatization gives m-xylene.
