Title: Improvements in electro-mechanical time delay devices
IPC: H03H9/30
Filed: 1946-06-24
Abstract: 618,881. Electromechanical retardation lines. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1946, No. 18852. Convention date, July 9, 1945. [Class 40 (viii)] [Also in Group XL (c)] An electro-mechanical time delay device comprises a polarized magnetic member, an input element coupled thereto at one point and adapted by magnetostriction to convert an applied electric wave into a mechanical wave in the member, and an output element coupled to the member at a second point spaced from the first where the mechanical wave is reconverted into an electric wave. The magnetostrictive rod 1 may be mounted between rubber blocks 2 and 3, to prevent reflection of the vibrations at its ends. The input coil is connected to a pulse generator P and the output coils 9, 10 and 11 are connected to amplifying valves 12, 12a and 12b. If the rubber blocks 2 and 3 are not used, coils may be arranged at each end of the rod connected to resistors which are adjusted to dissipate the vibration energy and thus avoid reflections. In an alternative method, a transformer at each end of the rod is connected up with a valve to superimpose on the rod vibration at each end a vibration of equal magnitude but opposite phase. The apparatus may be applied to a multiplex pulse system of telegraphy. A pulse generator P is connected to the delay device 1 which feeds trains of delayed pulses to the modulators Ma, Mb and Mc in which the pulses are modulated from signal stations Sa, Sb, Sc. At the receiving end the synchronizing pulse is similarly delayed by an apparatus 1 and causes demodulators Da, Db and Dc to restore the original signals.

Patent GB-1009449-A (GB)
Title: Method of, and apparatus for, heat treating granular materials
IPC: F27B15/00
Filed: 1962-05-16
Abstract: Clay is expanded by charging a reaction chamber with clay granules, injecting a jet of hot gas upwardly from the bottom of the chamber to maintain the granules in free suspension and to repeatedly circulate them vertically, and withdrawing gases at the top of the chamber. During the ascending part of the vertical circulatory movement, the granules are carried to a point near the top of the chamber where-upon they are caused to move downwardly and during their descent the particles return along the wall of the reaction chamber to the zone of gas entry into the chamber.  The process may be carried out in a conical reaction chamber 1 into which hot gas is introduced through nozzle 32.  A conical deflector 33 and deflecting plates 34 are situated at the top of the chamber. Clay granules are charged through gate 9 into chamber 8 to be preheated by exhaust gases from channel 7 prior to being charged into the <PICT:1009449/C1/1> furnace through inlet 11.  Hot gases are produced by combustion of fuel in burner 2, a duet 6 being provided to prevent flames from entering the reaction chamber 1.  Air is supplied by fan 5 through line 16 to cool the discharge from the furnace in chamber 24, the heated air then being supplied to the burner.  Air may be blown directly to the burner by closing flaps 17 and 18 whereupon air flows through duct 15.  This allows the expanded granules to be collected from chamber 24 through chambers 25 and 26. Hot gases may be withdrawn through lines 35 and 20.

Patent GB-473787-A (GB)
Title: Improvements in or relating to electric controllers
IPC: H02P1/20
Filed: 1936-07-10
Abstract: 473,787. Master control of motors. IGRANIC ELECTRIC CO., Ltd. July 10, 1936, No. 19153. Convention date, Sept. 6, 1935. [Class 38 (iii)] An electric control system includes means for effecting an operation of a switch and a device for delaying the operation, the device comprising a coil and means to energize the coil to prevent the operation of the switch, and to subject the coil to a reverse voltage, whereby, after a time interval depending upon the inherent inertia in the circuit of the coil, the operation of the switch is permitted. Upon operation of a start switch 4, Fig. 1, a main switch 2 is energized and the motor 1 connected across the supply, the operating coil 3a of an accelerating contactor 3 also being energized but the contactor prevented from operating by the energization of a coil 3b connected across the supply between a resistance R1 and a resistance R of lower ohmic value. The main switch maintains itself over contacts 2a and at contacts 2b completes a circuit from the supply through a comparatively high resistance h2 to reverse the energization of the coil 3b. The magnetic flux of the coil 3b is thus reduced and made to pass through zero and the switch 3 is then operated to short-circuit accelerating resistance r. The reverse circuit for the coil 3b completed by the contacts 2b may be supplied from a tapping on the accelerating resistance r. In a modification, Fig. 2, the accelerating contactor 15 has only an operating coil 15a which is energized upon operation of a start switch through resistances R, R1, to insert accelerating resistance r in series with the motor 1 and to complete at contacts 15b an energizing circuit for the main switch 2. This switch closes to complete the motor circuit and maintain itself over contacts 2a. It also closes at contacts 2b a reverse circuit for the operating coil of the accelerating contactor 15, including a comparatively high resistance R1, so that the magnetic flux produced by this coil is made to pass through zero whereupon the contactor is released and short-circuits the accelerating resistance r. The invention is described with reference to Figs. 3 and 4, (not shown), as applied to systems operating in a manner similar to those shown in Figs. 1 and 2, but including several steps of accelerating resistances r and a corresponding number of sequentially operated accelerating contactions and resistances R1, the reverse current circuits for each contactor being completed by the operation of the preceding contactor in the sequence.

Abstract: 1,124,793. Screen printing apparatus; pantographs. POLYPRINT Ltd. 30 June, 1966 [7 May, 1965], No. 19479/65. Headings B6C and B6P. In silk screen stencil apparatus for printing on the curved surface of a conical container the screen 19 is turned about a pivot point by a pantograph mechanism which is actuated in conjunction with the apparatus. The apparatus comprises the silk screen 19 which is rigidly fixed through arms 18 and extensions 17 to a member 16 pivotally mounted through a pivot 15 on a slide bar 14. The latter slidably supports a pivotally mounted plate 21 adjustably connected to the member 16 through rods 22 which, with the member 16 and the plate 21, constitutes a parallelogram type linkage. Mounted on the plate 21 is a control rod 25 the outer end of which incorporates follower roller 26 engaging the cam track 27 of a master pattern 28. The slide bar 14 is mounted on a carriage 12 which is movable along rails 11 upon actuation of a pneumatically operated motor. In operation of the stencil apparatus the carriage 12 moves along the rods 11 so effecting movement of the slide bar bodily sideways. Due to the engagement of followers 26 in cam track 27 the sideways movement of the bar 14 will result in a predetermined angular movement being imparted to the rod 25 and thence to the member plate 21 and the linkage 22 which will cause a corresponding angular movement to be imparted to the screen 19. In an alternative arrangement of apparatus the rod 25 and associated master pattern structure may project towards the member 16. In certain printing operations it may be convenient to dispense with the cam plate 28 and pivotally fix the outer end of the rod 25.
