Title: A method and apparatus for detecting during operation the degree of elongation of rolled magnetisable metal strips
Inventor: KUBO MORITADA
IPC: G01B7/287
Filed: 1969-07-11
Abstract: 1,270,440. Measuring elongation electrically. TOKYO SHIBAURA ELECTRIC CO. Ltd. July 11, 1969 [July 12, 1968(2)], No.35034/69. Heading G1N. Apparatus for determining during rolling the elongation of a magnetisable metal strip 1 comprises at least one pair of inductors 4, 4', spaced apart a predetermined distance #x in the direction of travel x of the strip and providing electrical signals indicative of the changes, of inductance caused by displacement of the strip along the yaxis at the positions of the two inductors, the difference of which signals, with respect to #x, is determined in a detector circuit 8, detector output signals being fed to a circuit 9 which produces signals proportional to the squares of the difference signals which squared signals represent the degree of elongation of the strip. The elongation at a plurality of points Z i , Z j , Z n  along the z-axis is determined, Fig. 2, using a plurality of groups of inductors and detectors. The distance #x is chosen to be less than one half-wave length of the shortest wave length of undulations found experimentally while the distance m#x over which a plurality of pairs of inductors is disposed is chosen to exceed one half of the maximum wave length of undulations. Detector circuit 8 comprises an A.C. source 6, a bridge circuit 5 having coils 3, 3' in two adjacent arms and a synchronous detector or rectifying circuit 7. An alternative embodiment of the detector Fig.8 (not shown) uses two magnetic cores (17, 17') spaced apart #x and having primary coils (18, 18') connected to an A.C. source (20), the secondary coils (19, 19') connected in series-opposition and the difference signal #y is squared in a circuit (21). Another embodiment Fig. 9 (not shown) is a simplified version of that of Fig. 2, using a single pair of inductors at each of a plurality of pairs of points along the z-axis.

Title: Rotary impulse tools
Inventor: SKOOG DONALD KURTZ
IPC: B25B23/145
Filed: 1965-08-17
Abstract: 1,074,078. Nut runners. INGERSOLLKAND CO. Aug. 17, 1965, No. 35287/65. Heading B3N. A nut runner T, Fig. 1, comprises a housing Af, containing oil, and a spindle rotated by a motor Df, and carrying a slidable blade (26f), Fig. 2 (not shown), the blade having an aperture (142) for controlling the applied torque and the spindle having a passage (144). The spindle may be non-rotary and the housing may be rotated. During rotation of the housing of Fig. 2 (not shown), or the spindle of Fig. 1, the oil normally passes through apertures (142), (144), until the ends of the blade (A<SP>2</SP> 5 ), (A<SP>1</SP> 5 ) are in sealed engagement with the cavity (2f) between points (B<SP>1</SP> 5 )- (C<SP>1</SP> 5 ) and (B<SP>2</SP> 5 )-(C<SP>2</SP> 5 ). At these points the oil in the (HP) section of the cavity is compressed and an impulse is applied to spindle 15f), or housing (Af), and therefore a rotatable impulse is applied to the nut which is being tightened, twice for each revolution of the housing or spindle. By increasing the length of slot (142), Fig. 2 (not shown), only one impulse per revolution is provided. In a modification, Fig. 3 (not shown), cavity (2g) is circular and two blades (26g) spring-urged apart, are provided. In a further modification passageway (144) is replaced by slots (148), Fig. 4 (not shown). The blade may have a low-pressure passage (312), Figs. 4c, 4d (not shown), connected to a high-pressure passage (314) via a spring-loaded poppet valve (310). Alternatively, a needle valve (310<SP>1</SP>), Fig. 4e (not shown), may be provided. In another modification, the pressure relief means is contained in the housing. In a still further modification, Figs. 5, 6, 6a (not shown), housing (Aj) has guide slots (150), and blade (26j) has projections (152) which are guided in the slots, and an oil by-pass (158) is provided.

Title: Injection syringe
IPC: A61M5/28
Filed: 1973-07-25
Abstract: 1431846 Syringes COMPASELECT GmbH 25 July 1973 [3 Aug 1972] 35408/73 Heading F1R [Also in Divisions AS and A6] A syringe has a contents scale and a comparison mark, either or both of which is displaceable relative to both the cylinder and piston to thereby obtain zero setting irrespective of the longitudinal position of the piston in the cylinder. A scale carrier 4 is frictionally held on a transparent cylinder 1 of a phial for use in a syringe frame. Zero of the scale 5 may be brought over the edge of piston 3 in any longitudinal position. An alternative construction provides graduated piston-rod 9, Fig. 3a, and a ring 11 carrying a mark 10. The ring is loaded by spring 13 into contact with shoulder 12 on the rod, when the mark is aligned with the scale zero. While the scale moves during an injection the ring is held relative to the cylinder by engagement between segmental abutments 16, 16a, formed similar to a screw thread on the ring and handle 8 respectively. Handle 8 is mounted on a phial so that the piston-rod engages the piston stopper of a phial. Engagement and disengagement between the abutments is effected by partial rotation of the handle, the ring being disengaged to be moved to the shoulder by spring 13 to reset to zero. In another construction abutments 16a are carried in a tube (14) Fig. 4a (not shown) fixed against rotation to the end of a phial. A handle (8) rotatably mounted on the phial and tube (14) and linked to the piston-rod by lugs and grooves (23, 17). In a modification the segmental abutments are replaced by a detent (19) Fig. 5 (not shown) releasably engaging serrations along the length of ring 11. An adjustable stop nut (22) Fig. 6 (not shown) on a threaded piston-rod provides a positive limitation of injection quantity. The preparation of solutions may be facilitated by provision of appropriate syringe scales, the syringe contents being injected into containers of solute of standard volumes.

Title: Improvements in or relating to telegraph transmitters
Inventor: HOWARD BERNARD
IPC: H04L17/04
Filed: 1958-11-04
Abstract: 892,222. Type printing telegraphy. TELEPRINTER CORPORATION. Nov. 4, 1958, No. 35441/58. Class 40(3). Precise timing of the transmitted signal in a telegraph transmitter is obtained by using timing cams, in known manner, to give exaggerated intervals and, in series with the contacts associated with those cams, a master cam co-operating with precision contacts to complete, and to give a precise switching of, the line circuit. A power source connected at 116, Fig. 29, feeds through a "Break" switch 120, one or other of the precision contacts 102, 108, and one or other of the pairs of timing contacts 1, 3, 5, or S, 2, 4, to the line connected at 118. The cams are connected via a half revolution clutch to a motor, the appropriate timing contacts being closed before the signal is to be transmitted and until after the signal has been transmitted. The circuit is completed by the precision contacts and master cam, and Fig. 28 indicates the contact closure periods for a five unit code transmission. The master cam 100, Fig. 21, has very small drops, for example 1/100 inch, so that the interval between the opening of contacts 102, 104 and the closing of 106, 108 is very small. The start cam ends the stop period accurately. Depression of a key causes a clutch release bar 158 (end view), Fig. 3, to be moved down thus causing a notch 170 in link 150 to pull the stop finger 144 out of engagement with a tooth 142 to allow the half revolution clutch to engage. The stop finger 144 is automatically returned to the position in which it will stop the clutch after a half revolution, even should a key still be depressed, since the link 150 is disengaged from the finger 144 on being raised by a cam 168 which is driven by the clutch. Repetition of a letter is brought about by actuation of a repeat finger 188 which moves to the right and keeps stop finger 144 away from teeth 142 for as long as "Repeat" key is depressed. An additional cam and camfollower system is provided to lock the code bars associated with the keyboard keys so that no other key can be depressed until the clutch has performed one half revolution, i.e. until the signal of that key has been transmitted. Specifications 799,956, 813,081, 833,941, 874,319 and 892,223 are referred to.
