Abstract: 1343646 Gauging stops; punching; stamping F DANN and C-F BERGNER [trading as RICHARD BERGNER] 6 May 1971 [8 May 1970] 13427/71 Headings B3W B3B and B3Q [Also in Divisions G1 and G4] A machine tool carries an indicator head consisting of two blind bores into one of which pressure is injected and from the other of which pressure escapes and which are connected by a third bore, the arrangement being that a pressure detector, e.g. a counter, is operated by the pressure escape from the second bore according to whether the third bore is blocked or unblocked. In the arrangement shown in which a cutter 8 severs lengths of wire 3, the wire is advanced until it blocks the third bore 4 when pressure entering at 30 and normally escaping through the third bore 4 operates a counter at 31. The head may be used to indicate the feeding of any strip material to an upsetting machine or cutting machine. In the arrangement of Figs. 3 and 4 (not shown), the passage of a head of a screw is used to block the third bore so operating a counter, while in the arrangement of Fig. 5 (not shown) the three bores are carried in the movable part of a stamping tool and the third bore is blocked by its approach to the work. In the arrangement of Figs. 6 and 7 (not shown), the three bores are carried in a cutting punch (20), the third bore, normally terminating within the punch, being opened to atmosphere if the tool breaks. In this case there is normally an escape of pressure through the second bore that ceases when the third bore is opened.

A video signal is sampled at random instants and if the amplitude of the sample exceeds a pre-set threshold level a binary number representative of the position on the picture to which the sample corresponds is fed to an analyser. The binary number comprises nineteen bits, nine indicating a particular line and ten indicating a position along the line. As described clock-pulses 20 enter 22 a " position-alongline " counter 24-33 which resets and carries into 23, 44 a " line-counter " 45-53 at a count of 672. Carries from these two counters provide line 63 and frame 66 synchronizing pulses. The video signal 69 is compared 70 with a preset 73 level and the result is sampled 68 under the control of a random pulse generator 75. At each sampling instant that the video signal exceeds the pre-set level counting is stopped 22 for eight clock-pulses, thereby providing time for the counts reached to be transferred 83 to an analyser 84. At the end of the eight clockpulse " pause ", a clock-pulse is entered directly 80 into the " 8-bit " stage 27 of the " position-along-line " counter-so that the counters remain in phase with the video signal -and the process continues. The video signal being analysed may be produced from a photograph of a nuclear event.

Title: Supersonic apparatus utilising piezo-electric vibrators
IPC: B01J19/10
Filed: 1946-05-07
Abstract: <PICT:0619872/III/1> <PICT:0619872/III/2> <PICT:0619872/III/3> A piezo - electric supersonic apparatus comprises a piezo-electric plate having a groove or a ridge formed in a nodal plane in its periphery and is resiliently held at the mouth of a casing filled with an insulating liquid by means of a resilient packing engaging the groove or ridge.  The invention is described with reference to laboratory apparatus for treating liquids, but is also stated to be suitable for use in a microphone.  In the arrangement shown in Fig. 1, a liquid 3 is subjected to the supersonic vibrations of a piezo-electric plate 1 having a groove 10 or a ridge 21 (Fig. 2) in its periphery which is engaged by a resilient sealing material 6 compressed between base-plate 7 and earthed metal casing 4.  If the liquid 3 is non-conductive, a mesh electrode 11 may be provided.  The lower electrode 14 is immersed in an insulating liquid 5 and held against the plate by a spring 15, while the lead-out for this electrode passes through an insulating tube 17 filled with similar insulating liquid, to terminal 16 which is connected to a coil 22. This coil, which may alternatively be flat and basketwound (Fig. 4, not shown) is cooled by a forced draught from fan 23.  Gas released from the insulating liquid is assisted to escape via tube 19 by tilting the apparatus.  To prevent absorption of the energy at the lower side of the plate, the electrode 14 is either made hollow or is spaced from the plate such that the transmission time through the gap and the electrode is a quarter of a vibration period.  The gap is adjusted by means of a micrometer head which may be fitted to the lower end of the lead-out, the electrode being in this case fixed rigidly to the lead-out (Fig. 5, not shown).  The alternative form of the apparatus shown in Fig. 6 is mounted on an adjustable arm 55. The material to be treated, represented at 44, is acted upon by piezo-electric plate 38 held as before by resilient packing 40. Electrode 52 is adjusted by micrometer head 51 in metal cap 39 and is immersed in an insulating liquid contained in insulating tube 37 made of a low-loss material.  Disc 44 is provided to support rod 53.  The surface of the material to be treated beneath the crystal is preferably coated with a film of oil to improve the transfer of energy.

Abstract: 919,750. Change - speed friction gear. SEEWER, G. A. April 18, 1961, No. 13912/61. Class 80 (2). [Also in Group V] In a dough-rolling machine in which provision is made for driving the run-off conveyer at a speed substantially equal to the peripheral speed of the rolls and the run-up conveyer at a lower speed, the shaft of the run-off conveyer is driven from the main rolls through a one-way clutch and in turn drives the run-up conveyer through a variable-speed friction gear. In the arrangement shown the fixed lower main roll 1 is driven by a reversible electric motor, the switch 37 of which is operated by a cam ring 34 on a longitudinal shaft 31 rotatable by a handle 32, while the upper roll 2 is capable of vertical adjustment by an eccentric 7 and rod 8 operated by a second longitudinal shaft 3 through a handle 6 integral with a scale 6a indicating the rolling gap. The conveyer rollers 19 are connected to a pinion 9 on the lower roll 1 by spur pinions 10 (not shown) and 12, and one-way clutches 16 of the jamming roller type, and the roller drive shafts 15 carry friction discs 28, 29 engaging between a central pair of discs 27 pressed together by spring washers 26. The discs 27 are carried at the lower end of an arm 22 freely rotateble about shaft 3, and may be moved sideways to vary the ratio between discs 28, 29 by rotating handle 32 and shaft 31, the latter of which is secured to a sector plate 38 formed with detent notches 41 and carrying a plate 40 provided with a vertical slot 39 engaged by the end of the shaft 23 on which friction discs 27 are mounted. Thus the direction of movement of handle 32 determines the direction of rotation of the lower roll 1 and which of the conveyer rollers 19 is driven through its associated clutch 16, while the extent of movement determines the speed ratio between the two conveyer rollers.
