Title: Method for the ultrasonic testing of tubes and bars
IPC: G01N29/26
Filed: 1972-07-28
Abstract: 1404222 Ultrasonic testing MANNESMANROHREN-WERKE AG 28 July 1972 [29 July 1971] 35491/72 Heading H4D A method of testing elongate articles comprises transmitting pulses from at least three transducers to circulate around a cross-section of the article, reflections from defects being detected at transducers other than the transmitter and wherein the transducers are rotated around the article in the same direction as the pulses travel through the article. Four transducers 4-7 are equally spaced around a ring 13 which rotates around the tube under test. All the transducers are mounted at the same angle to the radius of the tube. Each transducer is energized in turn and the next transducer acts as a detector for echo signals from flaws in the tube. As the ring rotates one quarter turn, the whole circumference is tested and the tube is advanced longitudinally by the width of the ultrasonic pulse. Testing speed is thus increased fourfold.

A knitting machine latch needle has the latch 2 formed as a plate pivoted on a slot between cheeks of the stem and adapted to swing from the back, Fig. 3, to the front, Fig. 1, to close the hook. The top edge 3 of the latch cooperates with the tip 10 of the hook to prevent ,the yarn being caught between the two. The back edge 5 of the latch is shaped to cam against the base of the needle trick and to cause the latch to close when the needle is lowered. The top edge 3 is also sloped to cause the yarn loop to press against it to open the latch when the needle is raised. Alternatively, the latch can be extended at its lower end as at 27, Fig. 11, to engage a cam 28 for positively closing the latch. Another arrangement provides a jack 29, Fig. 12, which is manipulated in sequence with the needle movement to engage the backs of the latches and close them. The latch may take the form of a U- shaped member engaging on either side of the needle stem.

Title: Improvements in change speed gearing
IPC: F16H3/24
Filed: 1919-11-17
Abstract: 160,419. Riise, J. Nov. 17, 1919. Variable-speed and reversing gearing; securing wheels on shafts.-Variable-speed gearing is arranged so that the position for reversed driving is passed through in changing from one forward speed to another. Driving and driven shafts 13, 17 are in line, a gear 14 secured to the former constantly driving a countershaft 24 through a gear 30. The shaft 17 is formed for a considerable portion of its length with gear teeth 19, upon which a gear 20 slides as on feathers. Similar gear teeth 26, 27 are formed on the shaft 24. An idler 28 is driven by the teeth 27. The highest speed is obtained by sliding a gear 34 upon the teeth 26 into mesh with the teeth 19. The second speed is a direct drive produced when the gear 20 is slid into clutch engagement with the gear 14. The third or low speed is obtained by sliding the gear 20 into mesh with the teeth 26. Between its end positions, the gear 20 must mesh with the gear 28, which yields a reversed drive. This reversed drive can be produced directly from any of the forward speeds. A gear 31 may be provided for driving a pulley as described in Specification 159,005, [Class 79 (ii), Motor vehicles, Driving &c.]. The invention is applicable upon motor-vehicles.

Patent GB-756833-A (GB)
Title: Improvements in or relating to tractor hydraulic systems and control valves therefor
IPC: F15B13/04
Filed: 1954-12-14
Abstract: 756,833. Valves. FORD MOTOR CO., Ltd. Dec. 14, 1954 [Dec. 28, 1953], No. 36115/54. Class 135. [Also in Group XXXI] In a hydraulic system for use on a tractor and of the kind in which the output of a pump normally runs to the sump but is diverted to pressurize a ram 14 on closing of a control valve 23c to shut off the passage leading to the sump, the seat 22d with which the control valve co-operates in the closed position is urged towards the valve by a spring 25, and the initial biasing force of this spring is less than the back pressure which builds up and acts between the valve and its seat whereby the build-up of pressure in the ram is slowed down. Normally, the output of the pump flows from a line 16, through a chamber 11a and a line 26 to a groove 22g in the seat member 22d. From the groove, the liquid can flow through a port 22e into the interior of the seat, past the open valve 23c, through another port 22f in the seat to a line 27 which leads to the sump past a pressure-reducing valve 28, the latter serving to maintain the pressure in line 27 higher than that in the sump. If a primary control valve 17 is moved to the left, either manually or due to implement draft or height, any pressure in the ram cylinder is released through a line 15, chamber 11b, passage 15a, axial passage 17e through the primary control valve, and out to sump through the openended chamber housing the biasing spring 18a of valve 17. On moving valve 17 to the right, the ram is again cut off from the sump and the output from the pump can now flow from chamber 11a through a passage 16a, around the neck 17f of valve 17, and through a passage 19 into a chamber 13a where it can act on the right-hand face of a piston 23a carried by valve 23c. The valve will thus be moved towards its seat to cut off the flow from line 26 to line 27. The pressure in chamber 11a will now build up slowly and will open a ball valve 11d and flow directly to the ram 14.

Abstract: 365,515. Weighing-apparatus. A. E. G.- FAHRKARTENDRUCKER GES., Hennigsdorf, Osthavelland, Germany. Oct. 9, 1930, No. 30283. Convention date, Oct. 9, 1929. [Class 143.] Computing-apparatus; printed records, apparatus for giving.-In a pendulum-weight scale for use in computing postal and similar charges, after the weighing-mechanism has reached its equilibrium position and a member corresponding to the district has been set, mechanisms are operated electromagnetically to point and indicate' information including the product of weight multiplied by a charge figure dependent on the district. A postage indicator 39, Fig. 1, postage totalizers 40, 41, and postage and weight type-wheels 42, 43 are all set by denominational rack rods 37 that are selected and differentially positioned by one of a series of blocks 85 operating through transverse bars 35. Each block 85 has associated with it a lever 33 and one of a number of plungers 18 .. 21 arranged in four arcuate banks, Fig. 2. The plungers of a bank all relate to a certain district. The bank is selected by depressing a district key and the plunger in the bank is selected by the pendulum 2 according to the loads on the platform. Upon the depression of a district key, an electromagnet 7 corresponding to the key is energized to lower a member 10 against the action of a spring 84. As the member descends, a cam surface thereon rocks a bell crank 11 to position the plungers 18 .. 21 vertically with the selected bank opposite a bolt 22 on the pendulum. Further movement of the member 10 allows contact 24 to close and energize an electromagnet 25, whereby a feeler pin 27 is moved into engagement with a plunger. If the feeler pin abuts one of the contacts 28 formed at the sides of the plungers, an electromagnet 29 is energized to move the plungers laterally so that the plunger of next higher order is positioned opposite the bolt 22. Upon the closing of contact 30, electromagnet 31 is energized and the bolt 22 operated to depress the plunger and set the printing and indicating elements. Finally, a contact 48 is closed to energize an electromagnet 49 and raise a platen 52 to press an inserted card against the type wheels 42, 43. Upon the return of the platen, a spring-urged lever 62 strikes the slidable end 59 of the card-holder and ejects the card. An operation counter 55 is actuated by a pawl 56 pivoted to the platen. An ink-ribbon 66 is wound on rollers 68, 73 rotated by pawls carried by a U-shaped member 67 mounted on the platen. When a roller is completely unwound the member 67 moves laterally to reverse the direction of movement. The totalizer 41 may be reset at any time by the depression of a pushbutton operating known zeroizing means:

Convention date, Dec. 19, 1945. Drawings to Specifications. [Class 41] Electrolytic oxidation of aluminium and its alloys and in particular refined aluminium is effected by an alternating current on which is superposed a direct current component in relation to which the articles to be oxidised are connected as anodes, the intensity of the direct current component having a value lower than the amplitude of the alternating current. The colours of the oxide layer are varied by varying the intensity of the direct current component, which is given a value of the order of one quarter of the total current strength. The electrolyte used may be oxalic acid. In one arrangement the positive pole of a direct current source is connected to the centre tap of the secondary winding of an A.C. transformer and the negative pole to an intermediate electrode in the electrolysis bath between the two aluminium anodes connected one to each end of the secondary winding. Alternatively two cells having a common anode connection may be employed with the negative pole of the direct current source connected to the centre of the transformer secondary winding, the cathodes of the two cells being connected one to each end of this latter.

Title: Roll Film Camera
IPC: G03B17/42
Filed: 1968-08-02
Abstract: 1,190,127. Photographic roll film cameras. FRANKE & HEIDECKE G.m.b.H. [trading as ROLLEI-WERKE FRANKE & HEIDECKE]. Aug.2, 1968 [Sept.23, 1967 (3)], No.37013/68. Heading G2A. A roll film camera has a detachable cassette 35 having an exposure aperture (not shown) which may be closed by a slide 39; a latch 29, pivoted at 36 to the cassette, being engageable with the slide 39 and with the shutter mechanism, such that the shutter must be cocked in order to attach the closed cassette to the camera, or to close the slide 39 if the open cassette is already attached. Also, when the cassette is closed, the shutter cannot be released; and moreover, a catch 3B, 7B; Figs. 8 to 10 (not shown) connecting the camera and cassette can only be released when the slide is inserted. As shown, the shutter is cocked by a crank 4 of a cog 1 which engages cogs 2, 3. Cog 2 may be connected to film transport means (not shown) and cog 3, via a releasable pawl (not shown), to a shutter cocking roller 5. Fig.1 shows the mechanism when the shutter is cocked. Depression of release button 20 moves a plate 26 into a vertical position via levers 19, 18, 14, 22, where it is held by a spring-pressed lever 8 when button 20 is released. When the slide 39 is inserted, it pivots lever 29 so that a pin 28 thereon, which extends through an aperture 27 into the camera, blocks vertical movement of the plate 26. Thus the shutter cannot be released when the cassette is closed. With the slide 39 withdrawn, a step 40A in the plate 26 enables it to avoid the pin and become vertical. When the shutter is released, the cassette cannot be attached to the camera, nor can the slide 39 be closed if the cassette is already attached, since the plate 26 blocks pivotal movement of the lever 29. Thus the shutter must be cocked to perform either of these operations. Aperture masks 43, 44, Figs. 5,6 (not shown), insertable in the slot for the slide 39, have cutaway portions 41, 42 to prevent their performing the locking actions of the slide. The rear of the cassette may have a slot 11A, Fig.7 (not shown) to accommodate the slide 39 after its removal from the exposure aperture. The back of the cassette may be hinged to enable film change without removal of the cassette. Insertion of the slide 39 may pivot a lever (16B, Fig.9) out of the path of a bar (10B), allowing manual depression of the latter to release the camera-cassette catch (3B, 7B).

Abstract: 862,950. Applying adhesive tape. CELLOPHANE INVESTMENT CO. Ltd. Nov. 3, 1959 [Nov. 3, 1958], No. 37332/59. Class 73. A device for applying lengths of adhesive tape to flexible articles has means for feeding the tape 3 on to a rotatable suction drum 22 and for bringing it, entrained on the drum, into contact ,with the article 'which is passed on to a collecting chute by gripping elements. The tape 3 is fed from a reel 1 by driven rollers 4 and 5 and receives on its adhesive side a "tear-off" strip 17 which is fed by rollers 12 and 13 from a reel 10. The circumference'of the drum 22 is equal to twice the required length of tape, which is fed on to it at zero tension and is held by suction over the sector 23 only. The article is first positioned on a table 24 by side guides 25 and stops 26. Pedal operation of a rod 30 withdraws the stops 26 and lowers the drum 22 to grip the -tape and the article between it and a driven roller 31. When the roller 31 has rotated the drum 22 through 180 degrees it stops, but the taped article continues on through the nip of a pair of driven rollers 32, 33 on to a shoot 41. During the application of the tape a fresh length has been fed on to the uncontacted side of the drum ready for the next application and is severed by a pivoted knife 37 which notches its ends to expose a tongue of the "tear-off" strip.
