Title: Method and apparatus for assembling two members one of which is internal and the other external, with the interposition of an elastic material, and a device constructed by this method
IPC: B25B27/28
Filed: 1930-04-14
Abstract: 341,802. Flexible unjointed hinges. THIRY, L., 19, Rue Vankeerberghen, Huy, Belgium. April 14, 1930, No. 11807. Convention date, April 26, 1929. [Class 65 (ii).] The invention relates to a method of assembling a joint consisting of internal and external members with elastic material interposed, the elastic material being extended by lateral compression, and consists in applying an external force to resist or prevent the extension of the elastic material in the direction of its smallest section during the process. In an arrangement for performing the complete assembly, the elastic material 4 is pressed into the external member 2 by a plunger 14 acting through a sleeve 13 and drift 5. The elastic material is forced to expand longitudinally by compression between the conical parts 7 and 5b, which are so arranged that the space between them is smallest at the rear, but extension in the direction of the smallest section is prevented by the part 13a. When the part 4 is fully inserted, lever 15 meets cam 7a, and disengages from the plunger 14 and engages notch 7d to prevent backward movement. The parts inside the sleeve continue to advance, and the elastic material is further compressed radially by the drift 5, extension in the direction of smallest section being again prevented by part 13a. The inner member 3 of the joint follows the drift 5 into its place. The two insertion operations may be performed separately and in any order, and the longitudinal extension of the elastic material in the direction of its smallest section may be only limited instead of entirely prevented. The external resistance to extension may be applied by fluid pressure, or by a deformable body in a limited space, instead of by a rigid member.

Patent GB-980175-A (GB)
Title: Improvements relating to the control of cyclic processes
IPC: C10J3/24
Filed: 1961-04-05
Abstract: A method for automatically controlling the performance of cyclic processes, e.g. in manufacturing or converting industrial gases with or without a catalyst, in which each cycle comprises at least one period during which a physical quantity, e.g. temperature, is varied, the manufacturing period, and at least one period during which the quantity is corrected (the heating period), comprises comparing the quantity with a predetermined value of that quantity, during one of the periods, and modifying the ratio of the periods, without altering their sum, in a sense to maintain the mean value of the quantity equal to the predetermined value.  A motor 1 rotates a finger 3 about a shaft 2 to actuate contacts 4, 5 once per revolution, the sum of the periods being equal to the time of one revolution.  Operation of circuit 4a terminates the manufacturing period and initiates a purging period, and subsequently the heating period which is terminated by operation of circuit 5a, a further purging period and subsequently the manufacturing period being initiated.  The purging periods are under a time control.  The contact 5 is carried by a lever 6 angularly adjustable about a shaft 7 by <PICT:0980175/C4-C5/1> <PICT:0980175/C4-C5/2> a motor 8, actuation of which is controlled by a switch 15, Fig. 2, operated by a pyrometer 18, the thermocouple 19 of which is located in the reaction chamber. As the temperature exceeds or falls below the predetermined temperature 20, it causes the switch 15 to actuate windings 13, 11 respectively in the motor 8 to adjust the lever 6 and hence the length of the heating period appropriately.  Adjustment thus proceeds continuously.  However, the circuit of the motor 8 may include a contact 21 which is only closed periodically, e.g. by a cam 22 which may or may not be driven by the shaft 2, so that opportunities for adjustment of the heating period can only occur periodically. The period of rotation of the motor 8 is much larger than that of the motor 1.  The contacts 4, 5 may be replaced by suitable pneumatic or hydraulic devices.  Specification 818,061 is referred to.
