Title: Improvements relating to distance sensing systems
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: G01S15/87
Filed: 1968-10-22
Abstract: 1285697 Position-finding EMI Ltd 3 Oct 1969 [22 Oct 1968] 50068/68 Heading H4D [Also in Division G1] Acoustic signals transmitted through the air, between transmitter-receiver devices on a ship and one or more transponders located at one or more reference points, are used to determine the disposition of the ship in relation to the reference point(s). In the Fig. 2 system for assisting the berthing of a tanker 1 at jetty 2, two pulse transmitting/receiving devices X, Y each interrogate two transponders A, B at fixed locations on the jetty to determine at least some of the distances AX, AY, BX, BY. Additional receivers (e.g. at Y<SP>1</SP>) may also be used. An analog (details given) or digital computer derives the ship's disposition from these distances and, optionally, from compass data. The several distance measurements provide redundancy for resolving positional ambiguity and checking system operation. Velocity data is derived from a series of distance measurements. A predictive display, showing the distances between bow and stern respectively and jetty 2 at which zero velocity would be reached for a given deceleration, may be provided in addition to a CRT display showing the ship's outline in relation to jetty 2. The transponder responses are coded for identification, e.g. by using a pulse code or by operating at different carrier frequencies, and the transponders may shift the frequency between reception and re-transmission to avoid acoustic feedback. The pulse repetition period and pulse length may both be reduced as the measured distance reduces. In conjunction with the above apparatus, electrodes in the jetty may be used to measure small distances between the ship and jetty by sensing capacity changes.

Abstract: 1305070 Drying gas streams J D ROBERTSON 27 Oct 1970 [31 Oct 1969] 51019/70 Heading B1L [Also in Division F4] Particulate plastics material stored in a hopper 11 for dispersing to a manufacturing process, is dried by continuously passing dry air through the hopper 11, the air being dried by passage alternately through desiccant tower 14 or 15, the desiccant in the tower not in use being regenerated by passing air therethrough at a temperature (above 400F) greater than the temperature (130F-350F) of the drying air passed into the hopper 11, the air pressure following a filter 28, for the drying air being monitored by a sensor 30 which halts the air flow when the pressure is too low. The pressure of the drying air in the hopper 11 is higher than that of the regenerating air in the tower not in use. Diverter valves 22 and 23 are operated by a solenoid 58 controlled by a timer 56 to switch desiccant towers 14 and 15, and light 61-64 indicate the function of the towers 14 and 15. Air for drying is drawn from the atmosphere or from the hopper 11 through conduit 25 and filter 28 by a positivedisplacement pump 29 and delivered to the drying tower 14. The dry air passes from the tower 14 to a heat exchanger 31 having a heating zone containing electric heaters 55, and a cooling zone containing refrigerator coils or finned tubes through which atmospheric air is blown by a fan 49, the heaters 55 and the fan 49 being activated by temperature sensors 32 and 34 so that the drying air is supplied within a predetermined temperature range. Air for regeneration is drawn from the atmosphere through a filter 38 by a blower 39 and delivered to an electric heater 40, to the tower 15 to regenerate it and to atmosphere at 35. A green light 70 is illuminated during normal operation but pressure sensor 30 activates an amber light 69 when the filter 28 is becoming choked, and a red light 68 (which operates cut-off switch 46) when the filter should be cleaned or replaced, or when the system is otherwise blocked. Hopper 11 (Fig. 4) receives drying air through conduit 26 which opens at 130 into a space 118 whence the air passes through holes 119 and an air dispersal sheet into the particulate material to tend to fluidize the material. Alternatively, hopper 11 (Fig. 5) contains an air grid 134 comprising perforated air conduits 135-138 in the form of a square and two parallel cross conduits 139 and 140, the conduits being supplied with drying air through a tube 146 at one corner of the square. The air grid may instead comprise a pair of concentric circular air conduits supported by fins from the portion 108 of the hopper 11, and supplied with drying air by a radial conduit.

Abstract: 1,134,690. Grippers for lifting rolls of paper. CASCADE CORP. 13 Nov., 1967 [19 June, 1967], No. 51639/67. Heading B8H. In a fork-lift truck attachment for lifting rolls of paper which has arms 14, 16, the movement of the arm 16 towards the load is slowed down at a predetermined point in its travel so that the arm 14 contacts the load first. This arrangement ensures that the arm 16, which is able to exert the greater pressure, still has some movement left after the arm 14 has been arrested, thereby allowing the full grip to be applied. To prevent the arm 16 pushing the arm 14 backwards, a check-valve is provided in the hydraulic circuit to the operating ram for the arm 14, Fig. 4 (not shown). The cam 14 is suspended by pivoted links 52, 76, and moves faster than the arm 16 for the same ram movement. To provide retardation of the arm 16 near the end of its movement, the operating ram 22, Fig. 3, has a piston 122 with a skirt 136 with an oil-seal 140 and an oil-passage 142. As the piston is moved to the left in Fig. 3 by oil under pressure admitted through a conduit 128, oil is exhausted through a conduit 126. When the oil seal 140 passes over the conduit 126 oil can only be exhausted at a reduced rate through the passage 142. Movement of oil in the opposite direction is not retarded as a passage 146 with a check-valve 148 is provided.

Abstract: 1366875 Controlling road-traffic PLESSEY CO Ltd 15 Nov 1971 [30 Oct 1970] 51698/70 Heading G4Q An inductive loop traffic detector system comprises a signal generator A, a tuned circuit which includes the inductive loop D, frequency sweep means for repeatedly varying in a sweep mode the tuning relationship between the output frequency of the generator A and the resonant frequency of the tuned circuit, and detector means for sensing changes in the signals produced in the tuned circuit by traffic in the vicinity of the loop. . In the embodiment shown, generator A produces a sawtooth waveform which is used to sweep the frequency of an oscillator B whose output is sinusoidal or a square wave. A feedbank controlled amplifier R supplies the swept frequency to the tuned circuit comprising loop D and capacitor E. A peals detector circuit comprising a diode F, capacitor G and resistor H has a short time constant and detects the peak voltage occurring every time the sweep generator A causes oscillator B to pass through the resonant frequency of the loop circuit. A further peak detector circuit comprising a diode J, capacitor K and resistor L behaves similarly but has a long time constant. Thus, when eddy-current losses occur in the loop circuit, due to vehicle presence, the detector circuit of short time constant reacts quickly, while the other detector circuit stores the previous, undisturbed peak voltage. Comparison of the detector outputs is effected in a comparator M which outputs to a relay N for the purpose of, e.g. control of traffic signals. The feed-back loop from the long time constant detector to the amplifier R offsets effects due to static metal in the roadway. The described arrangements eliminates the need for a setting-up procedure and drift-compensation following environmental changes. In another embodiment (not shown) the frequency of the oscillator is fixed, but a number of capacitors are connected to the loop in sequence under the control of a continuously-running clock and counter.
