Title: Engine testing apparatus
Inventor: HITCHCOCK KEITH NORMAN
IPC: F02B3/06
Filed: 1983-09-13
Abstract: An engine testing apparatus comprises an ultrasonic transducer 8 which directs a pulsed ultrasonic beam into an engine cylinder and converts the reflected ultrasonic signals into electrical signals. A sample/hold circuit 67 samples these signals at a time after each pulse when signals reflected by a piston ring passing through the beam are expected. A microcomputer 65 detects changes in the level of the sampled signal caused by the piston rings as the crankshaft rotates, and receives signals from a transducer 71 indicating the crankshaft position to allow top dead centre position to be found. The microcomputer receives signals from a microphone 51 directed at a fuel injector indicative to the onset of ignition and calculates the timing angle of the engine. The apparatus also calculates engine speed and detects piston slap. <IMAGE>

Title: Technique for transmission of voice communications and apparatus useful therein
Inventor: SCHWARTZ DR NIRA
IPC: H04J3/16
Filed: 1983-10-11
Abstract: In the transmission of communications one or more signals is sampled by a sampler 414 with sampling period t. Every n + 1 th sample is transmitted via a switch 415 and transmitter 416 and the intermediate samples are extrapolated from the (n + 1)th sample, n being an integer such as 5 or 10. The sampled amplitude of the signal at a time T is stored in a computer 426, and updated every (n + 1)th sample. The computer performs the extrapolation and sends corrections via the transmitter. Frequency modification apparatus 422 translates higher frequencies to lower frequencies. Transmission by differential encoding is described with the number of coding bits adapted to the sizes and signs of amplitude changes in a plurality of signals. <IMAGE>

Title: Flow controlling apparatus
Inventor: AKKERMAN NEIL HOOVER
IPC: E21B34/10
Filed: 1982-02-16
Abstract: Apparatus for use in a tubing string 10 in a well bore WB includes a body means 12 which has a bore 12A therethrough connected as part of the tubing string and which is packed off within the well bore. Means including a passageway 15,16 in the body means 12 bypasses the packer P to connect the annulus about the tubing string above and below the packer. The packer P is expanded into engagement with the well bore upon release of a means 24 for locking it in an inoperative position, and a means for so releasing the locking means includes a piston 25 in the passageway which is responsive to control fluid supplied through a control line 20 in the annulus which connects with the passageway. Upon release and setting of the packer, the piston 25 is removed from the passageway and circulation of well fluid through the connecting means between the annulus above and below the packer is controlled by a safety valve which normally closes the passageway, but which is responsive to control fluid supplied thereto through the same control line. Each of the means for connecting the control line with the passageway in order to release the packer, and alternatively establishing safety valve controlled circulation of well fluid through the connecting means comprise tools which are alternately landed within and retrieved from a pocket 13 formed in the body means to one side of its bore. <IMAGE>
