IPC: G01S1/02
Filed: 1969-10-13
Abstract: 1291130 Pulse radar HOLLANDSE SIGNAALAPPARATEN NV 13 Oct 1969 [18 Oct 1968] 50219/69 Heading H4D A pulse radar has two antennµ rotating synchronously about a vertical axis, one antenna having a wide beam perpendicular to the plane of rotation and an associated transceiver for determining range and a first angular co-ordinate of a target, the second antenna having a pencil beam and an associated transceiver for determining a second angular co-ordinate, wherein on reception of a video signal from a preselected target from the first transceiver a device releases the second transceiver to perform a scan over the beam plane of the first antenna coincidentally with the next pulse transmitted from the first antenna. Antenna 5 has a cosecsquared radiation pattern and continuously scans the azimuth plane driven by motor 6. The video signal is fed to a P.P.I, display 11 and the range and azimuth information on targets selected by a cursor on the display is passed to a computer 20 which sets the range and azimuth gates for tracking the target. The video signal also passes through a gate 38 controlled by the range and azimuth tracking pulses, and triggers a bi-stable 34. The change in state of the bi-stable 34 opens gate 32 and the next sync. pulse from generator 8 is passed by the gate and resets the bi-stable thereby closing the gate 32. The sync. pulse triggers the second transmitter 13 which performs a scan in elevation using a frequency dependent antenna 16 rotating synchronously with antenna 5. Antenna 16 is formed from a planar array of slot radiators fed from a dispersive supply line. The frequency of the pulse carrier is varied in equal steps by control unit 17 which variation alters the beam exit angle in small steps, the frequency of the received pulses being a measure of the elevation. The pulses received by antenna 16 are mixed in mixer 41 with signals from local oscillator 43 whose frequency is varied in steps equal to the steps of the transmitter frequency. The start of the local oscillator operation is delayed from the reception of the initial video pulse by one pulse repetition period of the first transmitter. This delay may be generated by the computer or by a delay line. This arrangement ensures a constant I.F. for the mixed video signal, whatever the elevation of the target. The elevation is determined by the time difference between the start of the local oscillator and the passing of a video signal by the second receiver to the computer. The video pulse also passes to a display 19.

Abstract: 1279612 Self-servo spot-type disc brakes DUNLOP HOLDINGS Ltd 23 Oct 1969 [25 Oct 1968] 50652/68 Heading F2E Parallel inclined abutment surfaces 13, 14, Fig. 2, are formed on radially-extending arms 3, 4, Fig. 1, of a fixed support member 2. Complementary abutment surfaces are formed on the leading and trailing edges of the right-hand friction pad 11 and backing plate 12 so that a self-servo effect is set up by the friction element 9 during application of the brake. A rigid link member 8 spans the arms 3, 4, on the other side of the disc, and this also has inclined abutment surfaces 15, 16; the parts 11, 12 of the left-hand friction element 10 are provided with complementary abutment surfaces to bring about the self-servo effect on braking. The friction pads 11 are cut away slightly at their trailing (upper, as seen in Fig. 2) edges so as to stand clear of the abutment surfaces 14, 16. The self-servo effect is assisted by providing each backing plate with a horizontal slot at its position of attachment. Thus, on the left, the slot is engaged by the enlarged head 21, Fig. 2, of a spigot 20 secured to the adjacent limb 19 of caliper 17, and on the right the other slot is engaged by spigot 32 formed on piston 23. The friction elements 9, 10, are thus permitted limited circumferential movement. This construction also ensures that the torque reaction is transmitted to the fixed support member independently of the caliper 17, which is slidable only axially. The pins 7 connecting arms 3, 4, with link member 8 are described as torque-taking members. Movement of the caliper 17 in a plane parallel to disc 1 is prevented by engagement of lugs 25 on the caliper with nuts 26, 30 on the ends of pins 7, on which nuts the lugs slide. Each abutment surface is rendered hard and low-friction by chromium plating or otherwise.

Abstract: 506,674. Tetrahydrofuranes. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Dec. 7, 1937, No. 33879. [Class 2 (iii)] Tetrahydrofuranes are produced by leading 1.4-butylene glycol or its C-alkyl, aryl or aralkyl substitution products in the gas phase over dehydration catalysts at temperatures above 100‹ C. but below those favouring substantial olefine formation. Generally about 220-350‹ C. is most suitable, but for alkaline-reacting catalysts, e.g. tertiary sodium phosphate, 400-450‹ C. Suitable catalysts include cuprous, aluminium or chromium oxide, alkali and alkaline earth salts, e.g. calcium chloride or carbonate, primary sodium pyrophosphate, primary and secondary calcium phosphate, sodium bisulphate, tertiary silver phosphate, mercuric phosphate, acid-forming oxides such as silicic, phosphotungstic, and phosphomolybdic, and their acid salts, and difficultly volatile acids, e.g. boric or phosphoric, on carriers such as pumice. There may be added substances capable under the reaction conditions of forming free phosphorus acids, e.g. amine phosphates such as butylamine phosphate. Inert diluent's, e.g. nitrogen, carbon dioxide or steam, may be present. When temperatures below the boiling point of the initial glycol are used, reduced pressure is employed to convert it to the gas phase. The products are separated by cooling, salting out with sodium sulphate, and distilling. In examples, 1.4-butylene glycol is led at 300-350‹ C. over precipitated chromium oxide heated to 900‹ C. and shaped; at 230-250‹ C. over precipitated alumina ; at 300‹ C. over secondary calcium phosphate; and 'at up to 450‹ C. over calcium chloride.
