Title: Improvements in electric switches
IPC: H01H50/00
Filed: 1921-09-21
Abstract: 183,414. Union Bag & Paper Corporation, (Assignees of Avery, T. M.). July 22, 1921, [Convention date]. Feeding and registering webs.- In a system for controlling the speed of a paper web travelling through a paper-bag machine as described in Specification 183,413, an electromagnetic switch is employed to control a reversible motor 41, Fig. 5, which corrects the speed of the web. The switch comprises a pair of electromagnets 26, 27, Figs. 1 and 2, adapted to attract armatures 8 on resiliently mounted contact arms 4, 5 and so bring contacts 11, 12 mounted at the ends of the arms, into engagement with fixed contacts 13, 14. The action of this switch is controlled by a device comprising a pair of contacts 52, 53 mounted on a shaft 54 revolving in timed relation with the mechanism to be registered with the web, current being led to these contacts through brushes and collector rings to which they are connected, and a controlling contact 59 situated between and freely rotatable relatively to the contacts 52, 53, the contact 59 being driven in accordance with the actual speed of the web. As the web and the contact 59 rotate relatively faster or slower than the shaft 54, the contact 59 is brought into engagement with one or other of the contacts 52, 53, closing the circuit of one or other of the electromagnets 26, 27, which in turn completes the circuit of the reversible motor 41 to enable it to run in one or other of its directions of rotation, and through a compensating device correct the speed of the travelling web. After the speed of the web has thus been corrected, the contact 59 is carried round between the contacts 52, 53 but does not touch either until a change in the relative speeds of the web and the machine renders further compensation necessary.

Abstract: 918,143. Sealing glass. M-O VALVE CO. Ltd. July 18, 1961 [July 18, 1960], No. 25058/60. Class 56. In a method of forming a flange on a glass tube an annular disc is coaxially supported with the tube and the adjoining region heated to soften the glass whilst the disc and tube are rotated about their common axis to cause the glass of the tube to be pressed into sealing contact with the disc by centrifugal force. The glass tube 9 is supported at its lower end in the recess 10 of the adjustable support 4 with its upper end projecting through and closely fitting the hole 11 at the centre of the annular graphite disc 1. The annular glass disc 2 providing the flange is fitted over the upper end of the tube 9 and rests on the graphite disc 1, located by closely fitting upstanding wall at the top of holder 2. An electric motor M drives the holders through gears 8 at the same speed. The holder 2 is preheated to 450- 500‹ C. and a gas burner 13 is arranged to direct a narrow needle flame at the region of the seal most heat being applied to the tube, whilst the holders are rotated at 1500 r.p.m. The centrifugal force generated by rotation causes the softened glass of the tube to seal to the inner edge of the annular disc. The seal area is then annealed and cooled. The flange and tube may form part of the apparatus for an electronic travelling wave tube. When a glass flange is required it is of the same composition as the tube. A composition is given in weight percentages: 65.4 SiO 2 , 15.8 B 2 O 3 , 5.7 Al 2 O 3 , 1.9 ZnO, 2.5 BaO, 0.9 CaO, 4.3 Na 2 O, 3.0 K 2 O, 0.3 F, 0.2 Sb 2 O 3 .

Title: Improvements in and relating to pulse-generating units
IPC: H03K3/53
Filed: 1960-07-20
Abstract: 883,292. Pulse generating circuits. AMP Inc. July 20, 1960 [July 24, 1959], No. 25236/60. Class 40(6). In a pulse generator of the type in which pulses are connected to a load through a latching type of electronic switch, a saturable inductor is connected across the load for regulating the voltage-time product of the output pulses and a turn-off voltage is derived from output pulse and applied to the switch after the pulse is applied to the load, the inductor remaining saturated until after the switch is turned off. In Fig. 1 a delay line 16 is charged through a resistor 14 from a voltage source 10 and then discharged through a load 42 upon the application of input pulse from a source 20 to a latching type switch 18 such as a thyratron valve or a similar transistor. A saturable inductor 36 is connected across the load and arranged so that when the desired product of voltage and time of the output pulse is reached the inductor saturates and effectively short circuits the load. The pulse applied to the load is also applied through transformer 24 to one end of a delay line 30 and to the other end of the delay line. The resultant delayed output pulse from the left hand end of line 30 occurs after the end of the required output pulse supplied to the load and passes through transformer 26 to switch off the switch 18. Meanwhile, the resulting output pulse from the right hand end of line 30 has maintained the inductor 36 saturated. Thereafter, the inductor is reset by winding 38. Resistances R1, R2 RN represent the windings of a magnetic core shift register constituting the load and preferably core 34 has the same characeristics as the cores of the load and is exposed to the same environment.
