Abstract: 1,018,169. Liquid blast switches. SIEMANSSCHUCKERTWERKE A.G. Dec. 31, 1963 [Feb. 18, 1963], No. 51463/63. Heading H2B. The movable contact rod 7 of a liquidimmersed switch is withdrawn from a fixed contact 1 through a nozzle like bore 24, a tapered channel 25 opening at one end into the bore 24 and at the other into the space 19 behind the nozzle. As the rod 7 is withdrawn an arc is drawn through the narrow annular space between an insulating tip 8 on the rod and the nozzle, into the chamber 19 causing an increase in pressure in chamber 19 which creates a flow of liquid through channel 25 to assist in extinguishing the arc. The contact rod 7 is supported from and electrically connected to fixed guide rods 14 by rollers 13.

Abstract: 1504174 Controlling tape recorders DICTAPHONE CORP 23 Dec 1975 [27 Dec 1974] 52672/75 Heading G5R [Also in Division H4] In a centralized dictation system, such as disclosed in Specification 1,504,175, successive messages recorded on a record medium, e.g. magnetic tape, at a record/reproduce station are separated by a signal, the tape drive control 161 being responsive to such a signal to inhibit the tape rewind function and thereby prevent a dictator gaining access to a previously recorded message. During dictation audio signals incoming at 42 are amplified at 48 and pass to record/playback transducer 54 via a FET switch 52, the latter being maintained open by the presence of a "dictate" signal at 44. When a dictator signals the end of a message, e.g. by going on-hook, the signal received at 110 actuates a timing circuit 124 which produces a pulse of predetermined length from gate 128. This pulse renders conductive FET gates 52 (via transistor 62) and 142 (via transistor 136), thereby allowing a 60 Hz signal to be applied to record/playback transducer 54. The pulse from 128 is also applied to forward drive solenoid 170. Hence for a predetermined period after termination of a message the tape continues in motion, recording a 60 Hz signal. When the signal is detected by transducer 54 during a rewind operation, it actuates a one-shot 154 to produce a second signal of predetermined duration. This signal is applied to rewind solenoid 166 to stop the rewind, and also to forward solenoid 170 to drive the tape forward a predetermined amount (to beyond the recorded inhibit signal).

[Also in Division H3] An inductive rod matrix read-only store uses a driver current source including an inductance for producing a linear current rise in a selected information wire. In Fig. 2, a pulse U applied at 17 renders a transistor 6 conducting to produce a driver pulse across terminals 14, 15 having a linear rise because of inductance 7, followed by a steep drop when pulse U ends. Resistor 8 is for discharging the inductance energy, RC circuit 12, 13 is a protective circuit, and Zener diode 11 is to fix the base voltage of transistor 6. The driver pulse across terminal 14, 15 is applied across terminals 4, 16 in Fig. 1 to pulse an information wire 1 1  1 2  or &c. in a ferrite rod matrix readonly store. which information wire is pulsed depends on the transistor decoders providing coordinate selection in Fig. 1. Each information wire is threaded with respect to each rod in one sense or the other according to the bit to be stored. Sense windings (one per core) such as 18 1  in Fig. 3 are connected at one end via respective diodes such as 24 1 , 24 2  &c. to amplifying transistors 25 (one per column of rods). A transistor decoder 21, by energizing one of lines 20, 20 1 , 20 3  ... renders conducting a transistor 19 respective to a row of rods to pulse the other ends of the sense windings of the row. This pulse, together with a positive pulse induced in a sense winding of the selected row from the information wire if a 1 (say) is stored at that position produces a pulse A from the respective transistor 25, but no pulse A is produced if the stored bit has the other value. Two driver pulse sources may be provided, operating in alternation.

Abstract: 1408318 Lasers WESTERN ELECTRIC CO Inc 13 Dec 1972 [13 Dec 1971] 57416/72 Heading H1C A fused optical fibre has a coherent optical pumping beam passed along its length to produce stimulated Raman emission of a lower frequency. In Fig. 1 a clad glass fibre 11 and associated objective lenses 16, 17 are positioned between dichroic resonator mirrors 14, 15, the fibre being end-pumped by a pump source 12 which may be a pulsed Xenon ion laser, a C.W. Argon laser, or a pulsed Nd : YAG laser having a frequency-doubled output. The pumping radiation passes directly through the glass fibre and its dichroic mirrors and is dispersed away from a receiver 20 by a prism 19. The resonator mirrors are reflective to the down-shifted frequencies produced from the pumping beam by Raman scattering, and cause stimulated Raman emission to pass through a lens 18 and prism 19 to the receiver 20. Limited tuning adjustment is obtained by varying the angle of tilt of the prism. In a modification, Fig. 6 (not shown), sub-picosecond output pulses are obtained by including a mode-locking DODC saturable absorption cell between lens 17 and mirror 15. A further modification, Fig. 3 (not shown), is the use of a Littrow prism having a mirrored back in place of lens 17 and mirror 15. Separation of the pump (beam and radiation produced by Raman scattering is obtained in Fig. 4 by the combination of a fixed lens 47 with inherent chromatic aberration and an axially movable mirror 45, the wavelength of light through the lens focused on the mirror being determined by the axial spacing. An amplifying system is shown in Fig. 5 in which pumping radiation is modulated at a dichroic mirror 64 by a beam from a transmitter 61 and is applied after conversion to stimulated Raman emission to a receiver 70. Suitable fibre materials are fused quartz, sodalime silicate and borosilicate.
