Title: Improvements in or relating to apparatus for submarine signalling
IPC: G10K11/00
Filed: 1920-07-19
Abstract: 151,585. Fessenden, R. A. July 21, 1919, [Convention date]. Receiving and detecting audible signals; subaqueous audible signals. - In apparatus for submarine signalling, the receivers, which may be of microphonic type, are placed in the acoustic shadow of a screen to protect them from disturbance produced by a signal transmitter on the same vessel, thus allowing the transmitting and receiving devices to be used simultaneously. The transmitter 13, preferably an oscillator inclined as shown, is mounted in oil or water in the forepeak 12 and is separated from the receivers 18, 19, which are mounted in separate tanks 16, 17 by a bulkhead 14, and preferably a second bulkhead 15, with a space 20 between. The contour of the acoustic shadow thrown by the transmitter 13 and bulkhead 14 is shown by dotted lines 22. The oscillator 13 is also preferably screened by horizontal bulkheads 24, 25, the former below the water-line 26. This allows the oscillator to remain immersed in a limited quantity of liquid without free surface, and increases its efficiency whether it is used as a receiver or transmitter. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is applicable to airships, but this matter does not appear in the Specification as accepted.

Abstract: 481,083. Cutting and dispersing semisolid substances. DUCKHAM, A., CASS, H. J., and DUCKHAM & CO., Ltd., A. Aug. 12, 1937, No. 22163. [Class 87 (ii)] Semi-solid substances such as upper cylinder lubricant are dispensed from a container by a combined cutter and ejector element which is so mounted that when actuated it first partially severs a portion of the substance from bulk, then advances the portion along the container to a discharge opening and finally completes the severance. The apparatus resembles a gun and comprises a barrel 1 containing a stick of lubricant and carried by a handle 2. The cutting element comprises a U-shaped arm 3 attached to a handle 4 and the transverse portion 5 of the element 3 carries a cutter 6 which is guided between flanges 9 on the barrel 1. The side arms of the element 3 embrace the handle 2 and are connected by a transverse rod 12 which moves in a slot 13 in the handle 2. The slot 13 is formed at its base with a member 15 mounted on a resilient cushion 17 of sponge rubber and provided with two depressions 16, 16a. The rod 12 normally rests in the depression 16a and on gripping the handles 2, 4 the cutter first pivots about the rod 12 and enters the plastic stick, the rod then travels along the slot 13 while the cutter 6 advances the stick towards the outlet of the barrel 1 and finally the rod 12 rests in the depression 16 while the cutter pivots further to sever the end portion of the stick completely. The stick is retained in the barrel 1 by a spring 24. In a modification, two spring-mounted balls are mounted in the slot 13 in place of the depressions 16, 16a.

Title: Improvements relating to servo systems
IPC: G05D3/14
Filed: 1949-06-16
Abstract: 683,924. Electric correspondence-control systems. FERRANTI, Ltd., and McCALLUM. D. M. Sept. 11, 1950 [June 16, 1949], No. 22257/50. Divided out of 683,889. Class 40 (i). An electric correspondence-control system for maintaining positional correspondence between input and output members comprises a first oscillator the frequency of which is controlled by the position of the input member, a second oscillator, whose tuning is controlled by the position of the output member, driven by a signal derived from the first oscillator, so that its output has the same frequency as that of the first oscillator but has a phase relative thereto, which is dependent upon the tuning, and a phase discriminator to which the oscillator outputs are applied to derive a d.c. output error signal having magnitude and sign dependent upon the extent and sense of the departure of the relative phase between the two signals from a datum value, the error signal being applied to a servo-motor coupled to the output member whereby, upon departure of the relative phase from its datum value, the servomotor is so driven that the tuning of the second oscillator is brought into correspondence with that of the first oscillator and simultaneously the output member is moved into positional correspondence with the input member. The position of input shaft 11 controls the frequency of the signal generated by oscillator 10, this signal being applied to amplifier and limiter 12 wherein it is converted to square-wave form and thence applied to phase discriminator 18, preferably comprising a ring modulator. A portion of the square-wave output is also applied via integrator 16, wherein it is converted to symmetrical triangular form, to oscillator 13 to drive it at the same frequency as oscillator 10. The tuning of the oscillator 13 which comprises a multi-vibrator, preferably of the cathode-coupled type, is controlled by the position of the output shaft 14 which is driven by servo-motor 22. The square-wave output from oscillator 13 is applied via amplifier 17 to the phase discriminator 18. When the two oscillators are tuned to the same frequency the outputs therefrom are in quadrature and the discriminator gives zero output. When, however, the shaft 11 is rotated with respect to shaft 14, the two oscillatory outputs cease to be in quadrature so that the discriminator 18 develops a d.c. output which, amplified at 21, so drives the servo-motor 22 that the shaft 14 moves into correspondence with shaft 11 and the two oscillatory signals return to their quadrature relationship.
