Abstract: 989,828. Machinery breaking pieces; linkwork. AB KARLSTADS MEKANISKA WERKSTAD. April 26, 1963 [May 18, 1962], No. 16433/63. Headings F2K and F2X. In the control linkage for a guide vane 5 of an hydraulic turbine or pump, a safety link connecting a control ring 2 with a lever 4 fast to the vane 5 comprises two link halves 11, 12, pivotally connected by a breaking pin 14 and coupled by a spring member which allows the link halves to rotate relative to one another when a predetermined load is exceeded. The spring member comprises cup springs 21 preloaded in compression by a nut 27 on a bolt 22 pivoted at one end to a lug 18 on the link half 12 and engaged at the other end 23 by a sleeve 24 which wholly or partly surrounds a breaking pin 19 in a lug 17 on the link half 11. The length of the spring member may be adjusted by a nut 26 on a bolt 25 passing through the pin 19 and fixed in the end 23 of bolt 22. With the link in compression, a small movement of ring 2 after obstruction of the vane 5 merely compresses the springs 21, allowing relative rotation of links 11, 12 while a large movement of ring 2 causes shearing of the breaking pin 19. Vane obstruction with the link in tension results first in failure of the pin 19 and, on further overload, failure of the breaking pin 14 which is subjected to a magnified load due to the bearing of a shoulder 15 of half link 11 against a face 16 of half link 12.

Title: Improvements in and relating to torpedo defence and the like
IPC: F41G7/00
Filed: 1941-12-30
Abstract: 581,361. Controlling apparatus by sounds. O'DWYER, D. M. Dec. 30, 1941, No. 16778. [Class 118 (ii)] Relates to a method of destroying hostile torpedoes or other objectives that emit sounds during use. According to the invention, a defending torpedo or other craft is steered automatically into contact with the hostile torpedo, the steering of the defending torpedo being controlled by a selective device which distinguishes the characteristic sounds of the hostile torpedo from otlier sounds and converts the selected sound waves into fluctuations of light which effect the steering control. The apparatus may consist of two microphones 7, 8, Fig. 1, mounted in the head 9 of the defending torpedo on opposite sides of the longitudinal axis. Each microphone is . connected to an amplifier 10 which controls the light emitted by an electric lamp 12 or 13, so that fluctuations of the sounds received by the microphones cause fluctuations of the light emitted by the lamps. The light from the lamps passes through inclined passages a, b in a "gate" 16 which has another passage c through which a cinematograph film 19 can be drawn past the crossing of the passages a, b. The light from the lamps 12, 13 falls on photoelectric cells 14, 15 respectively, which are connected in series with a battery k and a pair of relay coils 2, 3. which operate the steering control 5. The coils are connected with two other relay coils 20, 20a. The cinematograph film 19 is printed with a sound track, shown in Fig. 2, corresponding to the sound emitted by a hostile torpedo. The film is driven by a motor 18 through a clutch which is controlled by the relay coils 20, 20a. In use, the maximum amount of light from a lamp 12 or 13 is received by the co-operating photo-electric cell when the markings on the film are in synchronism with the fluctuations of the light from the lamp. When this occurs, the relays 2, 3 will control the steering until the amount of light received by each cell is equal, and the torpedo is then directed straight towards the hostile torpedo. The control of the clutch 21 by the cells 14, 15 through the coils 20, 20a serves to vary the speed of the film 19 through the gate 16 so that it tends to keep the film markings in synchronism with the variations of the light from the lamps 12, 13.
