Filed: 1970-04-28
Abstract: 1280609 Safety harness JIM ROBBINS SEAT BELT CO 28 April 1970 [28 April 1969] 20425/70 Addition to 1265726 Heading A3V [Also in Division F2] A vehicle seat belt retractor 16 includes a support 26 a reel (30) journalled on the support and adapted to receive a belt 18 and by a spring (38) urge it into a retracted position, a locking dog 52 mounted on the support and movable between a reel locking position and a release position (as in Fig. 4), the dog 52 being moved towards its release position as the belt is wound up, springs 88 and 62 urging the dog toward its locking and release positions respectively, and a time-delay device 68 responsive to unwinding of the belt past a predetermined angular position and engaging with the spring 88 to prevent locking for a predetermined time interval after such unwinding, a spiral groove 98 in cam 92 and follower 94 over-ridingly controlling motion of the dog in response to movement of the reel. The device 68 comprises a resilient diaphragm 76, e.g. of rubber, forming an expansible wall of an air chamber 78. As the dog 52 is moved into its release position it collapses diaphragm 76 and compresses spring 88. When the dog is moved from its release position the spring 88 urges the diaphragm from cup 74 against the differential air pressure on the two sides of chamber 78. Air flow into the chamber through a port 84 gradually expands the diaphragm which eventually uncovers a second port 82 allows the diaphragm to expand rapidly so moving the dog into a locking position. The predetermined time interval between unwinding of the belt past a set angular position and locking of the reel is thus governed by the size of ports 82, 84 and the resilience of the diaphragm.

Title: Terrain Avoidance System
Inventor: HOBAN THOMAS WILLIAM
IPC: G01S1/02
Filed: 1968-05-01
Abstract: 1,192,273. Pulse radar. NORTH AMERICAN ROCKWELL CORP. 1 May, 1968 [12 June, 1967], No. 20729/68. Heading H4D. In an airborne terrain-avoidance system a directionally ranging pulsed energy device is operated intermittently and computation responsive to that device and to its inertial motion predicts the locations of terrain obstacles when the device is not operating. The rate of operation of the device may be varied inversely with ground speed. The invention reduces the possibility of detection by e.g. a missile. General, Fig. 1.-Radar 10 and means 11 provide signals γn(R) in response to a transmitted pulse and indicative of the terrain profile along the direction of the projected flight path. Means 12, responsive to the radar and to the flight path angle γ, provides reference signals indicative of preselected manoeuvre limits γc as a function of radar range R. Means 13 affords a terrain-following control signal #γ(Rn) representing a "worst difference" between the sensed terrain profile and a synthesized manoeuvre-limited clearance; the control signal may automatically control the aircraft, or be fed to an indicator. The prediction computing means comprises a memory 14 which stores terrain position data from the radar and a computer 15. Geometrical and detailed considerations. Fig. 2. Distance Lo represents a minimum vertical clearance. A clearance surface 23 is shaped to limit premature "fly-up" and is synthesized by signals generated in means 12 which prevent generation of a signal at the output of means 13 when a sensed terrain obstacle lies below the clearance surface. As the aircraft progresses from point 21, computer 15 and memory 14 co-operate, after the radar is turned off, to correct range (R) and altitude (h) data stored in the memory. If the radar data for point A at a time T 1  subsequent to data R 1 , h 1  are R<SP>1</SP> 1 , h<SP>1</SP> 1  and the changes in aircraft position during that interval are #R and #h the equations R<SP>1</SP>1 = R 1 -# o <SP>T1</SP> V g .dT, where V g  is ground speed, and h<SP>1</SP> 1  = h 1  + #h are utilized. Altitude data are stored in the corresponding range "bin". When predicted range decreases to a predetermined value, a data point is dropped from the memory. On subsequent operation of the radar the memory is refilled with new data. The maximum interval T max  between successive radar operations is shown to be - inversely proportional to Vg. To allow for the effects of shadows (Figs. 3, 4, 5, none shown) an extrapolation function is included in the prediction computation. It may be arranged to switch on the radar before its due time if the memory 14 is unduly depleted. An outline of memory 14 and computer 15 is described, Figs. 6, 7 (neither shown).

Abstract: 1291573 Constant voltage devices ROSEMOUNT ENG CO Ltd 28 Jan 1970 [23 April 1969] 20826/69 Heading G3X [Also in Division H2] An intrinsically safe circuit arrangement for coupling a load 16 to an A.C. supply 13 comprises a transformer 10 having an inductor 12 in series with, and a capacitor 14 in parallel with, the primary winding 11; the winding 11 and the capacitor 14 constituting a parallel tuned circuit which is resonant at the supply frequency and which has a Q-factor at resonance such that the current flowing in the primary winding 11 at resonance is sufficient to partially saturate the core of the transformer whereby the load current is limited to a safe value, the inductor 12 being effective to limit the primary current in the event of an open-circuit or short-circuit of either the capacitor 14 or the primary winding 11. The circulating current in the parallel resonant circuit 11, 14 depends on the Q-factor thereof which will be modified by the reflected impedance of the secondary circuit 20. The Q is chosen so that over the required range of secondary current, the current in the primary winding 11 results in partial saturation of the core 10. This results in a reduction in the permeability of the core 10 with a consequent change in the Q of the resonant circuit 11, 14 and the system therefore provides a constant output voltage as the load current increases-up to a limit where the inductance of the primary winding has fallen to a point where the circuit can no longer support resonance. At this point the primary inductance falls rapidly to a low value and the secondary voltage then collapses almost to zero. An earthed screen is provided between the primary and secondary windings of the transformer 10 and the elements 10, 12, 14 may be encapsulated to form a single unit.

Abstract: 149,208. Huth Ges., Dr. E. F. April 29, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Wireless signalling. - The local oscillator in a heterodyne receiving-apparatus is connected to the receiving-circuit through an intermediate aperiodic circuit with the object of attaining equality of amplitude of the received and the local oscillations. In the arrangement shown in Fig. 1, a primary receiving-circuit 1 and a secondary receiving-circuit 2 are provided, to either of which the telephone 7 or other receiver or amplifier can be coupled by adjusting a switch 8. The local source 4 energizes an aperiodic circuit 3 which is coupled to both receiving-circuits 1, 2, and either coupling may be made ineffective by short-circuiting switches 5, 6. When the telephone 7 is connected to the primary circuit 1, the switch 6 is closed and 5 is open, and when the telephone is connected to the secondary circuit 2 the switches 5, 6 are reversed. The amplitude of the local oscillations in the receiving-circuit 1 or 2 is controlled by varying the couplings of the intermediate circuit 3 or by varying its resistance. In the modification shown in Fig. 2, the secondary receiving-circuit 2 is utilized as the aperiodic circuit by providing a switch 10 for short-circuiting the condenser 9. When the switch 8 is in the position for connecting the telephone 7 to the secondary circuit 2, the switch 10 is open, whilst with the other position of the switch 8 the condenser 9 is short-circuited and the circuit 2 acts as an intermediate aperiodic circuit. The various switches may be operated conjointly.
