Title: A process for manufacturing a single-bed patterned article of knitwear
Inventor: GRIMM HELMUT
IPC: D04B9/00
Filed: 1982-09-02
Abstract: A plurality of stitch-forming elements pass successively through two knitting systems, and in each system a yarn 5 or 6 fixedly associated therewith is respectively laid into all elements which are intended to receive yarn in accordance with the pattern in that system such as for wales 17, 18, and 19 and which therefore pass through in a yarn- receiving position, so that floating yarn portions 28,29,30 or 23 are produced on the back of the elements which are not intended to receive yarn and therefore do not pass through in a yarn-receiving position. The floating yarn portions are tied off in wales 11, 14 and 22 by their being brought to the front side of at least one selected element which is not intended to receive yarn before the selected element passes through that subsequent knitting system in which it is intended to receive yarn in accordance with the pattern. The selected element is not withdrawn into the cast-off or knock-over position before passing through said subsequent system whereby the floating yarn portions instead of being loose as at 25,26 and 27 in course 2 are tight as at 28,29 and 30 in course 3. The floating portions may be tied in the same way in every other wale 11, 13,15. Arrangements for effecting the process on a circular knitting machine are also described. <IMAGE>

Patent GB-2143634-A (GB)
Title: Optical sensors
Inventor: HEEKS JOHN STUART
IPC: G01J9/02
Filed: 1983-07-13
Abstract: An optical sensor, operating via interferometric techniques, comprises a single mode optical fibre path (12) around which light beams (10a, 10b) are sent in opposite directions before combining and producing interference in the plane of a photodetector (13). A sensing region (14) is disposed asymmetrically in the path (12) and application of a perturbation to be sensed to the sensing region (14) causes corresponding phase modulation of the photodetector output. If tau  is the transit time in the path, the phase modulation occurs at perturbing frequencies around 1/(2 tau ). For improved sensitivity (Fig. 5) an offset bias of  pi /2 phase between the two light beams is applied, the sensor then being responsive to frequencies around 1/(4 tau ). For fibre path lengths in the range 1 metre to 500 metres, the corresponding sensor response frequencies are 100 kHz to 50 MHz. <IMAGE>

Title: Flowmeter prover
Inventor: HAYWARD DR A T J
IPC: G01F25/00
Filed: 1983-10-25
Abstract: A compact flowmeter prover comprises a calibrated pipe (100) and a piston (112) sealed against the pipe wall and displaceable within the pipe by the fluid to be measured. The pipe (100) is a removably and replaceably mounted within an outer casing (103). Inductive proximity detectors (101a), (101b) sense the passage of the piston. Leaks past the piston seals (118a), (118b) are detected by means of pressure changes in a liquid filled coiled tube (123) which is compressed as the piston moves. The piping and valves are arranged to provide a positive hydraulic hold to prevent premature movement of the piston at the beginning of a run. The piston carries actuators at each end and measurement starts when the rear actuator passes the first detector and ends when the front actuation passes the second detector. This reduces the effects of leakage through the piston seals. <IMAGE>

Filed: 1983-11-10
Abstract: A time switch driven by an electric clock motor is disclosed. The time switch has a base plate above which a time dial with on and off-trippers are rotatably mounted. Disposed below the base plate are other components including input and output terminals, switch means electrically connected between the terminals, switch activating means for closing and opening the switch means in accordance with the positions of the on- and off-trippers on the rotating time dial, and gear train leading from a rotor of the motor to the time dial. The motor comprises the rotor which is a bipolarized permanent magnet and an electromagnet in the form of a ring interrupted by a gap in which the rotor is located. In the base plate there is formed a generally annular groove for receiving the electromagnet, such that the electromagnet, a constituent of the motor, is received within the thickness of the base plate to reduce the depth required for the motor disposed below the plate. The components of various kinds to be disposed below the base plate are arranged to be packed together substantially in the same plane parallel to the base plate to reduce the depth required therefor. These space saving structures are combined to reduce the depth or thickness of the whole time switch assembly.
