Title: Generator voltage regulators
IPC: H02J7/16
Filed: 1973-07-04
Abstract: 1432404 Automatic voltage regulators NI I EXPERIMENTAL INST AUTOMOBIL ELEKTROOBORUDOVANIA I AVTOPRIBOR AND PAL MAGNITON 4 July 1973 31847/73 Heading G3R In a voltage regulated generator system, an A.C. generator is self-excited, using a voltage regulator, from the rectified generator output that is also used to charge a battery. The regulator input is connected to the battery through a first diode, and to the generator field winding via a second diode and resistor in parallel. The second diode enables energization of the field winding from the battery during generator starting, and the resistor supplies the field excitation voltage to the regulator input when the connection between this input and the battery becomes open-circuited. In the embodiment shown, the output of generator 1 is rectified at 5 and fed to the battery (not shown) and via diode 27 to the input of regulator 8. Transistor 10 in the regulator is switched on and off according to whether the regulator input is below or above the breakdown voltage of Zener diode 15, to vary the current in field winding 6 and thus to regulate the generator output. Upon starting of the generator with switch 23 closed, the battery initially discharges via diodes 26, 27 to energize the field winding 6. In the case of the generator to battery or battery to regulator connections becoming open-circuit, the output of the generator is fed via a further rectifier 7 to the field winding 6, and via resistors 24 and 25 (diode 27 being blocked) to the regulator input, to maintain the voltage regulation. In an alternative Fig. 2 (not shown) rectifier 7 is omitted and the field winding connected to the star point of the generator. In the regulator, the transistors may be replaced by thyristors.

Title: A toy ticket dispenser
IPC: A63H33/30
Filed: 1956-10-20
Abstract: 829,203. Issuing tickets. BERWICK, K. D. Oct. 16, 1957 [Oct. 20, 1956], No. 31992/66. Class 106 (3). A toy ticket dispenser comprises a container enclosing a roll of ticket paper and a ticket advance mechanism operable by means of a dial on the outside of the container which dial is rotated to deliver a ticket, the length of the ticket being determined by the degree of rotation of the dial. The container 1, Figs. 1 and 2, is of a moulded plastic material such as polystyrene and is in two parts, the rear part being removable, formed with slotted lugs 17 to receive shoulderstraps. The ticket paper 5 passes from a roll 6 in a casing 7, between a drum 2 having an outer rubber tyre 3 and a leaf-spring 4, between guide walls 8, and out through a slot 9 formed with a sharp edge 10 for tearing off the issued ticket. The drum is freely rotatable on internal projections of the container, and is formed with internal rack teeth 13. A spindle 11 has secured to it a disc carrying a spring-steel pawl 12 co-operating with the teeth. Secured to the spindle is a dial 14 having finger-holes 15 and a recess in its lower face housing a coil-spring, one end of which is attached to the dial and the other end to the front face of the container. In operation, a finger is inserted in a hole 15 and the dial rotated (clockwise in Fig. 2) until the finger abuts a stop 16 on the container, thus feeding the ticket paper, the length fed corresponding to the dial rotation and being presumed to correspond to the fares shown in the holes. The coil-spring returns the dial to normal position against a stop (not shown), the spring 4 preventing reverse rotation of the drum. Alternatively, the spring 4 may be replaced by a small roller having a resilient surface, the drum surface being provided with serrations.

Title: Inhibition of corrosion of aluminium alloys
IPC: G21C15/28
Filed: 1958-10-08
Abstract: 847,981. Preventing corrosion. ATOMIC ENERGY OF CANADA Ltd. Oct. 8, 1958 [Oct. 8, 1957], No. 32135/58. Class 123(1) Corrosion of aluminium-nickel alloys containing from 0À5 to 5% of nickel which are immersed in flowing water at a temperature of from 150 to 350‹C. is inhibited by adding silicic acid to the water to form a thin, durable coating of a complex aluminium silicate on the alloy. The amount of silicic acid added ranges from 100 parts per million to that amount which produces saturation at the working temperature and is preferably from 800 to 1000 parts per million. The acid may be added by adding sodium or potassium silicate and removing the cation in a cation exchange bed connected in parallel with the water flow system until the pH of the solution is not less than 5, the resulting solution then being equilibrated with a standard mixed ion exchange bed to maintain its concentration, purity and pH level. The invention is of particular application to the protection of the fuel rod sheaths in a water-cooled nuclear reactor, the silicate being added to the recirculating cooling water flow. To produce an initial film of silicate on the sheaths they may be heated to working temperature in a solution of silicic acid for a period of from one to seven days.

Title: Improvements in line-carrying rockets
IPC: F42B12/68
Filed: 1946-10-30
Abstract: 617,739. Line-carrying rockets. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. Oct. 30, 1946, No. 32173. [Classes 9 (ii) and 77] A rocket comprising a front casing 1 and a rear casing 7 axially movable relative to each other has a propellent composition in each casing, means being provided to ensure substantially simultaneous ignition of each composition. Secured to the rear of the front casing 1 is a collar fastened to which are sleeves 3 carrying rods 4. The rods 4 are slidable in sleeves 5 fixed to a collar 6 on the front end of the rear casing 7, the movement of the rods being limited by stops 8. The collar on the rear casing has two additional sleeves 9 carrying rods 10 hinged to a bridle 11 for the attachment of a line. To fire the rocket the bridle 11 is bent away from the rods 10 and the rear casing 7 inserted in the barrel of a discharger containing a cartridge, the collar 6 of the rear casing abutting against the end of the barrel and the rods 4, 10 being outside the barrel. On firing the cartridge, the flash from it ignites the propellent composition 20 in the rear casing and at the same time passes along an axial passage 24 through the plugs and composition of the rear casing to ignite the propellent composition 14 in the front casing. The rocket then moves forward with the casings spaced apart by the rods 4 (see Fig. 2). The gases from the burning propellants escape through apertures in the plugs and chokes at the rear of each casing. In an alternative arrangement, the rear casing slides within an apertured extension of the front casing, an annular abutment at the end of the extension engaging with plates at the front of the rear casing to limit its movement. Instead of filling the casings with a propellant burning outwards, a pressed cylinder of propellant may be inserted spaced from the walls of the casings by projections or spiders. Ignition may be from the flash of a cartridge, the flash passing through the annular space around the propellant in the rear casing to ignite the composition in the forward casing. Alternatively, a fuze may be led from the propellant in the forward casing through the annular space in the rear casing and joined to a fuze from the second propellant, both fuzes being ignited simultaneously.
