Title: Ultrasonic testing of solid material
IPC: G01N29/265
Filed: 1971-06-11
Abstract: 1356020 Ultrasonic inspection devices COMMISSARIAT A L'ENERGIE ATOMIQUE 11 June 1971 [12 June 1970] 27491/71 Heading H4D In a method of testing for flaws lying in a plane of a workpiece by pulse-echo ultrasonic inspection, the or each ultrasonic probe is moved relative to the workpiece to scan it and the motion is such that the time between transmission of a pulse and reception of the echo from the point being inspected is kept constant. This enables ready distinction between a flow echo and spurious blips in an oscilloscope or oscillograph display, since the displayed flaw echo will be stationary relative to the displayed transmitted pulse. Two transmitter-receiver probes 13, 13<SP>1</SP> connected in parallel are used in the Fig. 4 embodiment for transverse wave inspection of plate weld 12. Probe 13 is moved along a line PQ oblique to the plate surface 15 such that wave travel time over path EDCDE is constant for different inspected points C. Similarly probe 13<SP>1</SP> is moved to keep path ABCBA of constant travel time. The form and orientation of a flaw can be determined from inspections over these paths and also over path ABCDE. The angles of lines PQ, PN relative to plate surface 15 are selected in dependence on the wave velocities in plate 11 and in the medium (water or a coupling wedge), and on the wave incidence angles α, α<SP>1</SP>. The three wave paths may be made equal. In the Fig. 6 embodiment transmitter probe 17 is moved along line GH while receiver probe 18, focused on the inspected point C, is moved along line DE. These movements are provided by two screw-threads, which rotate at the same speed but have different respective pitches, and are such that path ABCDE is of constant duration, Further transmitters, e.g. with two moving symmetrically in relation to the path of the receiver, may be used. In a modification a transverse-wave transmitter-receiver is moved along a line oblique to plate surface 15, and a longitudinal-wave transmitter-receiver is moved along a line normal to surface 15 (Fig. 7, not shown). A single transmitter-receiver probe moving along a line oblique to surface 15 is used in a further embodiment (Fig. 2, not shown).

Abstract: 1,185,165. Modulation. PLESSEY CO. Ltd. 19 June, 1967 [21 June, 1966], No. 27621/66. Heading H3R. A modulation system similar to that shown in Fig. 4 of Specification 1,172,976 is used in a binary data transmission system to produce the effect of a frequency shift system requiring reduced bandwidth. The input data is fed directly and through a delay (units 14-16, Fig. 2) to a logic circuit 13 which opens one of four gates 17-20 according to the particular combination of the current input bit and the preceding bit. These gates allow one of four signals namely or Œ1, to pass through a filter 21 to modulate a carrier signal cos w 0 t, (T is the bit period). Another carrier signal sin w 0 t is modulated by and the two modulated signals are added to provide the final output. The two carriers may be derived from the same source by means of a phase shifter, and the three sinusoidal modulating signals may be derived from clock pulses at the bit frequency via a bi-stable circuit 4, a filter 5 and a phase shift circuit 22.

Filed: 1927-10-19
Abstract: 286,571. Hoe & Co., Ltd., R., (Hoc & Co., Inc., R.). Oct. 19, 1927. Bed-reciprocating apparatus.-A matrix-rolling machine, consisting of a reciprocating table carrying the chase, matrix, and blanket, and a pair of pressure rollers, is arranged so that a slip can take place between the rollers without interfering with the movement of the table in case of excessive pressure between the rollers and table. The driving-roller 6 carries a gear-wheel 16 meshing with a gear-wheel 17 loose on the shaft of the roller 5, and a second gear-wheel 18 engaging with a rack 19 on the table 2. The outer face of the wheel 17 is formed with a recess with which engages a cone-clutch member 24 non-rotatable but slidable on the shaft 11 of the roller 5. Adjustably mounted by means of a screw 30 on the end of the shaft 11 is a plate 29 serving as an abutment for springs 28, the other ends of which engage in recesses in the face of the clutch member 24. If a pressure greater than that to which the springs 28 have been adjusted occurs, due, e.g. to the use of a thicker blanket, the gear-wheel 17 and the clutch member 24 will slip relatively to one another while the table continues its movement, thus avoiding breakage.

Title: Improvements in and relating to coin exchanging mechanism
IPC: G07F5/24
Filed: 1935-10-14
Abstract: 467,261. Coin - freed change - giving apparatus. NEWCO CHANGE MACHINE CO., Ltd., and NEWALL, W. F. Oct. 14, 1935, No. 28348. [Class 27] In coin-exchanging mechanism such as described in Specifications 366,658, 400,527, and 423,123, the coins of lower denomination after use in a prepayment meter or other coinfreed apparatus fall to a hopper 14, Figs. 1 and 2, at the bottom of which is a delivery slide 13 of sufficient depth to contain a number of coins forming change for a coin of higher denomination inserted through a slot 27. The slide 13 can be pulled out, when freed, through an aperture in a front plate 11 and slides in a guide 12. It is normally locked by one end of a detent lever 19, pivoted at 17, engaging in a gate 16 carried by the slide and extending forwardly from the rear end of the latter. The gate is provided with a notch 23 and shoulders 24, 34 which permit further movement of the lever 19 to discharge the coin of higher value, and to ensure a full outward movement of the slide. The higher value coin rests on a foot 22 of the lever 19 being retained thereon by the lower edge of the coin insertion shoot until the step 24 permits its further downward movement. The coin tilts the lever 19 to withdraw its nose 21 from the locking notch 23. When the hopper 14 is full, surplus coins are directed by projection 42 therein through an inclined opening 41. The slide is pressed upward in the guide 12 by a presser plate 32 acted on by leaf springs 33. This prevents a coin from jamming between the top of the slide and the guide. Coin-slit closing-devices.-When there is insufficient change in the hopper 14, the lower inclined end of a lever 25, pivoted at 26, enters a slot therein. The upper end of the lever 25 then obstructs the coin-slit 27. Fraud preventing.-To prevent operation by a wire &c. inserted through the slit 27, the shoot for higher value coins is sinuous, such coins travelling over reversely inclined members 35, 36, 37. A side wall of the guide 12 extends between the slide 13 and the detent 19 and prevents the detent from being actuated by an instrument inserted through the opening for the slide in the front wall 11.
