Title: Acoustic measuring instruments eg flowmeters or level gauges
IPC: G04F10/00
Filed: 1979-05-15
Abstract: An acoustic wave travels from transducers 8 along path I to receiver 9. A counter 5 supplied by controllable oscillator 1 is made to count to a predetermined count repetitively to produce signal W, and the time difference between the production of signal W and the arrival of the acoustic wave at receiver 9 (signal Z) is determined at 7, and is used to control the frequency of oscillator 1 to make the count time of counter equal to the acoustic wave transit time t whereby the frequency of oscillator 1 provides a measure of the transit time. A circuit 13 generates a pulse of predetermined width a predetermined time after signal W starts. The output t +  tau  of receiver 4 which detects the arrival of the acoustic wave is compared with this pulse to provide a degree of abnormality detection. If the output t +  tau occurs outside this pulse, the propagation of the acoustic wave is regarded as abnormal. <IMAGE>

Patent GB-2073366-A (GB)
Title: Hydraulic shock absorbers
IPC: F16F9/512
Filed: 1980-04-08
Abstract: The present specification discloses a twin-tube, telescopic hydraulic piston and cylinder apparatus for use as a vehicle shock absorber. In such shock absorbers hydraulic lock can occur in the event of high velocity large impacts being applied. This is clearly undesirable as it results in a hard ride. The present invention seeks to overcome the above problem by applying the hydraulic pressure prevailing in the compression chamber 11 to a displaceable wall 42 which is supported by resilient means 44 acting in series opposition to said hydraulic pressure. Thus the wall 42 can yield to create a temporary increase in volume of said compression chamber 11 whenever the hydraulic pressure in the compression chamber 11 exceeds a value predetermined by said resilient means 44. Thus the possibility of hydraulic lock and a hard ride is reduced. The wall may instead slide in the inner tube 10 and carry the foot valves 32, 34. <IMAGE>

Two map picture magazines A, B (cassettes), each with a projection lamp 1,2 are used to provide, via a rotatable mirror 4, objective lens 5, rotatable prism system 9, and projection lens system 8, a suitably oriented map image on screen 7. <IMAGE>
Patent GB-2081944-A (GB)
Title: Microinstruction sequence control
IPC: G06F9/26
Filed: 1980-10-08
Abstract: A microinstruction sequence control provides control over the sequence of microinstruction operations performed by a digital computer processor. The microinstruction sequence control allows microinstructions to be fetched from a memory at the same time as microinstructions are executed by an arithmetic logic unit. By decoding and fetching an estimated microinstruction 310, the register 222 allows branching to occur in a microinstruction program, wherein the direction of branching is determined by the results of the immediately previous microinstruction. Through the use of a conditioning logic unit 328, subroutine calls involving a microinstruction stack are implemented, and a recovery microinstruction is provided, should the estimated microinstruction prove to be incorrect using control flip-flops 312,314,316 and a recovery translator ROM 336. The incorrectly estimated microinstruction is flushed out using a delayed pop from flip- flop 340. <IMAGE>

Title: Method and apparatus for dissolving gas in a liquid
IPC: B01F5/04
Filed: 1980-12-17
Abstract: An improved apparatus for dissolving gas (particularly oxygen) in liquid (particularly sewage) has an inlet pipe (2) for liquid communicating with the top of a vertical generally cylindrical chamber (8) whose outlet (12) projects a small distance into a horizontal generally cylindrical chamber (16). The liquid undergoes a reduction in velocity in passing from the pipe (2) to the chamber (18), and a change in direction and further reduction in velocity in passing from the chamber (8) to the chamber (16). Bubbles of gas are introduced into the liquid in the pipe (4) from an inlet pipe (6) for gas. Some of the bubbles are carried into the chamber (16) with the liquid. Turbulence created by the change in direction of the liquid helps to disengage undissolved gas from the liquid in the chamber (16). Such bubbles enter the gas space (22) and the gas collected in chamber (24) and returned via recycle pipe (32) to the pipe (4). Oxygenated liquid is discharged through the outlet (34).
