Title: Apparatus for measuring water depth
IPC: G01S7/64
Filed: 1975-12-24
Abstract: 1536690 Sonar T FUKUMOTO 24 Dec 1975 [25 Dec 1974] 52827/75 Heading G1G [Also in Division H3] In measuring the depth of water or fish by sonar, the echo time is measured by counting clockpulses, frequency scaled according to a selected range, and indicated by energizing one of a column of light emitting diodes 16. For long range work the LEDs correspond to 5 meter increments of depth. Generator 1 outputs clockpulses having a 1À2 msec period (the time for an echo from an object 1 meter from the transducer). The clockpulses are frequency divided by 5 and counted by a counter 11, reset to zero when a sonar pulse is transmitted, the count being transferred to a latch 12 when the echo is received. There are seven short ranges A-G, for each of which the LEDs correspond to 1 meter increments, the lowest value differing by 10 meters between adjacent short ranges. Thumbwheel 25 is used to select the desired short range and also positions a cylinder 27 carrying the scale markings. For short range work the clockpulses from generator 1 are fed to counter 11, without frequency division, after a number corresponding to the lowest point of the selected range has been counted by a counter 5. Flip-flop 7 is reset after 16 further pulses have been delivered by generator 1.

Abstract: 1332494 Cushioning piston stroke MONSUNTISON A B 9 Nov 1970 [7 Nov 1969] 53286/70 Heading F1D A device for cushioning the end of the stroke of a piston 6 reciprocal in a cylinder 1 comprises a cylindrical sleeve 8 projecting from the piston rod 5 and having a plurality of radial holes 11. Near the end of the piston stroke, the sleeve 8 enters a bore 3 concentric with cylinder 1. An annular slotted sealing ring 12 is located in an annular recess 13 in bore 3, the recess communicating with the piston chamber 15 by means of passages 14. On the downward stroke, Fig.1, the sleeve 8 slidingly engages sealing ring 12 and the fluid being pushed by piston 6 is then throttled through holes 11 at a reduced rate, thus cushioning the piston stroke. The holes 11 are cut off progressively thus damping the stroke more and more till the end of the stroke is reached. On the return stroke the ring 12 is raised by sleeve 8 thus transmitting fluid to chamber 15 via passages 14 to raise piston 6. Holes 11 can be replaced by longitudinal recesses in bore 3, the sealing ring being retained in an annular recess in the sleeve Fig.2, (not shown).

Abstract: 1,127,164. Spinning yarns. ALGEMENE KUNSTIJDE UNIE N.V. 16 Dec., 1965 [18 Dec., 1964], No. 53500/65. Headings D1F and D1W. In each of three embodiments of fixed or portable, hand- or pedal-operated apparatus, filaments are interlaced or tangled to join ends of yarns or strands e.g. of glass fibre, by means of turbulent gas e.g. air or saturated or unsaturated steam. The ends are inserted in aligned slots in concentric tubular members so as to project into a blowing chamber; one member (or plunger) is moved within another member (or plunger cylinder) to close the chamber; gas supplied to the chamber through a central tubular nozzle flows past the filaments and is rendered turbulent, as by a resonance chamber coaxially aligned with the nozzle, and the filaments are thereby interlaced. The blowing chamber is connected to a muffling discharge channel, comprising a muffler space lined with sound absorbing .material and of effective diameter larger than that of the nozzle exit. whence the gas escapes from the apparatus. The gas supply is then arrested to cause or initiate return movement of the plunger to the position .in which the blowing chamber is opened and the joined ends may be removed from the realigned slots. The slots may be adjustable to accommodate strands or yarns of different count; components defining the relative disposition of the chambers and nozzle may be adjustably located. The apparatus embodies a permanent magnet whereby it is attached to a support surface. The gas supply and pressure may be automatically controlled and regulated.

A method of grinding a gear comprises engaging a hob 4 and the gear 13 while the gear is rotating freely and then engaging a drive to the gear, the hob 4 having a tapered or plain entry portion 26 of rubber or plastics to guide the initial meshing.  The gear 13 is mounted on mandrel 12 between centres 11, 10, the latter being rotated by a motor 6 through gears 7, 8 and a shaft 9. The mandrel can be clamped to the shaft 9 by supplying fluid pressure to a chamber 18, Fig. 3, to move a sleeve 16 downwardly against springs 23 thus clamping collet fingers 21 against the end 12A of the mandrel. In operation, the gear and hob are each rotated out of contact at the correct operational speeds by synchronous motors 3, 6. The sleeve 16 is then released so that the gear continues to rotate merely by a frictional drive from the centre 10. The hob is moved axially to take up engagement with the gear which adjusts itself to a correct meshing relationship. The sleeve is then moved downwardly to drive the gear positively.  In a modification, the hob and gear are rotated by a common motor. The gear may be rotated initially merely by the frictional drive.
