Title: Improvements in or relating to apparatus for measuring distance
IPC: H03K7/00
Filed: 1947-01-27
Abstract: 636,886. Radiolocation. SUBMARINE SIGNAL CO. Jan. 27, 1947, No. 2446. Convention date, Feb. 7, 1946. [Class 40 (vii)] [Also in Group XL (b)] A radar system comprises a pulse generator, a receiver and a common transmitting and receiving antenna which is coupled to the generator and receiver by a delay means introducing a delay longer than half the sum of the length of the generated pulse and the time taken for the receiver to recover after the break-through of the transmitted pulse. The receiver is therefore prepared to receive echo signals from and indicate the presence of objects although the objects may be only a very short distance from the equipment. In a simple arrangement, Fig. 1, the transmitter 1 and receiver and indicator 2 are connected through a T.R. switch 5 and through wave-guide 6 to a wave-guide switch 7 which either couples the apparatus through delay line 10 and switch 11 to antenna 9 or which connects directly with antenna 9 over connection 8. When delay line 10 is inserted, the apparatus can be used to view objects down to zero range, but owing to the attenuation caused by the passage of the transmitted and received wave energy through the line the maximum range is reduced. Use of the direct connection 8 enables a greater maximum range to be observed. In a more complex system, Fig. 2 (not shown), a switch is provided to change from the near to the distant range and this at the same time as it introduces the delay line for the near range also introduces a delay in the path of the triggering pulse used to initiate the time sweep of the indicating cathode-ray oscillograph. The switches 7 and 11 in the wave-guide feed to the antenna may be as shown in Figs. 2 or 3. In Fig. 2 the section 15 may be rotated about the axis of feeding guide 6 to its alternative position 16. The choke flanges 13 and coupling plates 14 avoid loss at the junction points. In the alternative arrangement, Fig. 3, the guide 6 is split into two branches and rods 19 or 20 may be inserted into holes 17 or 18 to present a high impedance to the passage of energy into the respective branch guides.

Title: Improvements in the production of oxide coatings on aluminium and its alloys
IPC: H01G9/00
Filed: 1932-01-27
Abstract: 374,806. Electrolytic production of oxide coatings on aluminium and its alloys. VEREINIGTE ALUMINIUMWERKE AKT.-GES., Lautawerk, Lausitz, Germany. Jan. 27, 1932, No. 2472. Convention date, Dec. 18, 1931. [Class 41.] Coatings having special qualities such as hardness, flexibility, and dielectric strength are produced by the use of direct current and alternating current in succession in either order. The procedure may be repeated several times. In an example, an aluminium hot-plate is treated in a 10 per cent solution of oxalic acid first with continuous current of current density 2 amps per square dcm. for 20 minutes, then immediately with alternating current of current density 5 amps per square dcm. for 1 hour. The coating is coarse-grained and elastic but not particularly hard. In another example, an aluminium band of thickness 0À1 mm. is drawn through a bath containing 8 per cent oxalic acid at 35‹ C. and treated by alternating current of density 2 amps per square dcm. ; it is then passed through a similar bath at 20‹ C. under continuous current. The coated band may be curved to a radius of 50 mm. without formation of chinks and is resistant to electric puncture at 1000 volts. In another example, the inside of an aluminium container for receiving hot slightly concentrated hydrochloric acid is first oxidized using alternating current and then treated with continuous current in an electrolyte cooled to 15-20‹ C. The layer is impregnated with melted wax at 150‹ C and dried in a furnace at 100‹ C.

Abstract: 1530171 Radar NATIONAL RESEARCH DEVELOPMENT CORP 13 Jan 1977 [22 Jan 1976] 02504/76 Heading H4D In a miniature pulse Doppler radar, e.g. one using a Gunn diode, a smaller battery power source is enabled by producing the local oscillator signal in pulses only, substantially coinciding with the echo pulses. As shows the echoes must be from very near targets, as the L/O pulses are produced directly from the T x  pulses. Otherwise the range must be known and a delay inserted. The Doppler product of the mixing 9 is gated through to smoothing integrator 13 by gating pulses also coincident with the L/O pulses. The integrator output is the Doppler signal and an indication is given if the amplitude thereof is greater than a threshold V T

Abstract: 1432932 Projectile fuzes DIEHL 21 Jan 1975 [4 Feb 1974] 2520/75 Heading F3A A base, central or nose fuze with a selfdestruction mechanism for a spinning projectile, comprises: a pivoted lever 17 locking a spring- loaded striker 19; a pivoted catch 8 engaging a free end 15 of the lever to retain it in its locking position; a strut 13 preventing clockwise movement of the catch under the action of a spring 10; a centrifugal mass 9 carried by the catch; and a cam 28 carried by an inertia member 25. When a projectile fitted with the fuze is launched, the catch, under the action of centrifugal forces, moves anti-clockwise to permanently disengage the strut 13; but the lever 17 is retained, until, on impact with the target, the member 25 is thrown or swung forwards and the cam 28 drives the catch 8 clockwise against the action of centrifugal forces so that the end 14 of the catch disengages the locking lever 17. A spring 22 then drives the striker 19 into a detonator 3. In the event of a miss, selfdestruction occurs when the spring 10 overcomes the centrifugal forces acting on the catch. In a nose fuze, Fig. 4 (not shown), the cam surface (49) is motivated by a plunger (51) that is driven inwards on impact with the target.

[Class 102 (i)] In a fuel-injection pump two plungers 2, 3 are driven out of phase by means of two cam shafts 15a, 16a. The plunger 2 controls the suction passage 7, while the plunger 3 controls the discharge passage 8, the plunger 2 entering the passage 7 from above, thus avoiding the entraining of gas bubbles. The cylinder bores 12, 13 are connected by a passage 14 and, on the closing of the suction passage by the plunger 2, the volume of the space between the plungers remains approximately constant until the plunger 3 opens the passage 8. The space between the plungers then decreases, and discharge takes place through the passage 9. On the suction stroke the space between the plungers increases when the plunger 2 opens the passage 7. The out of phase relationship of the cams may be variable in order to vary the discharge. For this purpose one of the gear wheels 27 connecting the shafts 15a, 16a is adjustable angularly on its shaft by means of a sleeve 35, which is axially adjustable by means of a rod 40 and coupling 37. The sleeve 35 engages the interior of the wheel 27 by means of a quick thread, and also engages the shaft by means of a key 34. The pump may comprise a number of identical cylinder blocks 5 clamped together by means of bolts 41. The assembly comprises also an intermediate casing 25 and a cam casing 23 common to all the cylinder blocks.
