Title: Improvements relating to crystal oscillator circuits
IPC: H03B5/34
Filed: 1954-10-05
Abstract: 755,087. Generating oscillations; pulse radar. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 5, 1954 [Oct. 9, 1953], No. 28666/54. Classes 40 (5) and 40 (7). A crystal is shock excited by a unidirectional steep electrical wavefront and after a predetermined number of oscillation cycles and at a selected instant of a cycle a reverse voltage step is applied to stop immediately the oscillations. As shown, a crystal 3 is shock excited by pulses from a mono-stable flip-flop circuit 11, applied to it in push-pull from an amplifier 2, the crystal being in a balanced bridge circuit so that pulses from the amplifier 2 are not transmitted to the output of the bridge. The oscillatory output is then amplified at 4, squared at 5, differentiated at 6 and the resulting pulses applied to a counter circuit 7 so that during every nth period of the-oscillation cycle a pulse is applied to a circuit 8 of adjustable and selected delay (e.g. another flip-flop) whose output restores the first flip-flop 1<SP>1</SP> to its initial stable condition so that a further voltage from flipflop 11 is applied of opposite-going polarity to the crystal to stop the oscillations. The flipflop 11 may be triggered to unstable state by a radar synchronising pulse, and the pulse output at M from the differentiator 6 may be applied to a radar presentation screen as time-base calibrating pips.

Title: Improvements in guided missile control sets
IPC: F41G7/30
Filed: 1957-09-12
Abstract: 1,121,351. Electric correspondence control systems. L. BOLKOW [trading as BOLKOW ENTWICKLUNGEN, K.G.]. Sept. 12, 1957 [Sept. 13, 1956], No.28833/57. Heading G1N. [Also in Division G2] A sighting and control device for a guided missile comprises means for producing two superimposed images of the target and the missile respectively, and means for bringing the images into coincidence and thereby deriving a control signal which will direct the missile on to the target. In Fig. 3 the target is viewed directly through glass plate 12 and the missile by reflection from the mirror 13 through a colour filter 14 which distinguishes the two images. The mirror 13 is gimbal mounted and movement of the mirror gives a measure of the angular displacement of the missile from the line of sight. A rod 18 is connected to the control lever 16 of the mirror by a nut engaging a screw thread on the lever and is driven down the lever at a rate proportional to the velocity of the missile; at its other end the rod 18 is connected to the gear member 20 of a linkwork; thus the joint 24 of the linkwork is moved proportionately to the product of the range of the missile and its angular displacement, i.e. the lateral displacement of the missile. A piston 28 moving in a cylinder 27 in another arm of the linkwork working in conjunction with a spring 36, produces a movement of joint 21 proportional to the time derivative of the lateral displacement. Thus the movement of the tap 33 on potentiometer 34, which produces the control signal at terminal 35, is a linear function of the displacement and its time derivative. When the missile is on course switch 38 is closed and any deviation off course, resulting in tap 33 being moved, causes motor 39 to operate to displace tap 40 and cause a signal at terminals 35 to restore the missile to the line of sight. In another arrangement, Fig. 4, the coupling of the control lever 45 to the addition gear has a constant transmission ratio, the dependence on time being taken into consideration by a controller drum 50, rotated by a motor at a speed proportional to the speed of the missile. The drum has two conducting surfaces separated by an insulating saw-tooth parting strip, the two surfaces being connected by sliding contacts to each end of a battery. The control signal appears at terminals 58 from contact 57 and is proportional to the angular displacement, through the coupling from control lever 45, and inversely proportional to the range of the missile as measured by rotation of the drum, since the saw-tooth has a uniformly changing amplitude, so that a constant lateral displacement produces a constant control signal. When the missile is on course, switch 38 is closed and any deviation, which causes lever 45 to be moved, produces an output from tap 60 which operates motor 65 to move the pivot point 67 in such a way that the signal given is increased.

Title: Nuclear reactor assembly
Inventor: MARGEN PETER HEINRICH
IPC: F22B1/02
Filed: 1964-07-13
Abstract: 1,074,345. Reactors. ATOMENERGI A.B. July 13, 1964 [July 19, 1963], No. 28888/64. Heading G6C. [Also in Division F4] An integral pressurized water reactor comprises a pressure vessel 2, the lid of which is also the tube plate 9 of a heat-exchanger 7, the tubes 10 of which are U-shaped and connected at their ends to apertures in the tube plate 9. The heat-exchanger 7 consists of a pressure vessel 8 secured to the reactor pressure vessel 2 by means of flanges 4 provided on both vessels and bolts 5. The reactor core (indicated by broken lines) is mounted above a pump 11 with driving motor 12 and a partition 25 extends through the core in the form of a tube. The water in the pressure vessel 2 is maintained at the desired pressure by a pressurizer through a tube 15 and is forced upwardly through the tubular partition 25 by the pump 11. The partition 25 is plane adjacent the tube plate 9 and on descending becomes more and more curved until it finally changes into its tubular form immediately above the core. The tube plate 9 is consequentially divided by the partition 25 into two semicircular parts and each of the heat-exchanger tubes 10 has one end connected to an aperture in each part. Coolant flowing up through the core is deflected by the partition 25 (as shown by the arrows) through the apertures in one semi-circular part of the tube plate 9 and it passes around the U-shaped tubes 10 before leaving the heat-exchanger through the apertures in the other semicircular part and flowing down the outside of the tubular partition 25. The water in the heat-exchanger is heated to boiling and flows by self-circulation (as shown by the arrows) through a first water separator 18 of known type and then into the upper part 20 of the heat-exchanger which acts as a steam dome and contains a second water separator 19 and a bottom 26 for the separated water which is provided with an outlet pipe 27. Feed water is supplied to the heat-exchanger through a conduit 16 and the steam produced discharges through a conduit 17. The reactor pressure vessel 2 is made of a radiation-resistant material, e.g. stainless steel, while the heatexchanger pressure vessel 8 is suitably made of carbon steel or low alloy steel. To allow for the different thermal expansions of the pressure vessel materials, the flange connection between the two vessels should be such as to permit radial movement between the tube plate 9 and the flanges 4, e.g. by means of roller bearings 21. In an alternative embodiment, a cylindrical partition extends up through the core as far as the tube plate and each of the U-shaped tubes has one end connected to an aperture in the plate within the central area defined by the partition and the other end connected to an aperture in the plate within the surrounding annular part.

A device for damping the rolling of ships comprising angularly movable stabilizing surfaces (22 in the embodiment shown in Fig. 10 and 4 in the embodiment of Figs. 1, 2) has a two part gear, one part being driven continuously by an electric motor 1 and the other part being reversible and connected through a lever 15 to the shaft 16 about the axis of which the stabilizer moves to damp the rolling motion of the ship, the two parts being interconnected through an electro-magnetic coupling 2 actuated by a gyroscope (not shown) and thus influenced by rolling movement of the ship. When the coupling 2 is energized, a brake 5 is automatically lifted by a releasing magnet 6 and a shaft 20 is driven until moving and fixed contacts 7, 8, which are set manually or controlled by a second gyroscope, align to interrupt the current to the coupling, thereby limiting the angle of rotation of the stabilizing surfaces. The shaft 20 carries a member 14 which slides in yokes 17 on the lever 15, which yokes allow the stabilizer to be rotated into the hull. In the embodiment of Figs. 1 and 2 this latter rotation takes place about a horizontal shaft 12 having levers 11 connected to pistons in cylinders supplied with oil by an electric pump, the electrical connections being such that the pump is inoperative when the motor 1 is running and vice versa. The aperture in the hull side is covered by a slide member 18. In Fig. 10 the stabilizer 22 is rotated in a horizontal plane about a vertical shaft 21 into a chamber 24.
