IPC: G09B23/10
Abstract: 113,787. Gueugnon, F. Feb. 24, 1917. [Convention date]. Gravity, measuring force of.-In recordmg apparatus for demonstrating the theoretical laws of mechanics connecting masses, acceleration, &c. and times of movement of bodies having under forces, (such as gravity), of the Atwood's machine type, and of the kind employing a moving drum and paper strip contacted by a pencil moved in function of time, movement is transmitted to the drum by means independent of the paper strip, for instance by a wire and pulley, so that the movement of the strip may be according to any desired ratio. An easily-running pulley 1 has mounted upon its shaft a drum 2 covered with a rubber sleeve over which passes the paper strip 4 slightly stretched by two small weights 5; or preferably the paper strip consists of a slightlystretched endless band suitably guided. A pointer 6 is mounted in front of the strip. The pulley partakes of the movement to be observed; in the particular case illustrated, a wire 7 passes over the pulley and is connected to two equal masses M, an additional small mass m is added to one, and the system allowed to move under gravity. The pencil 6 is carried by a pendulum 8 mounted upon pivots 9. The system is released by the pendulum when passing through its vertical position. In a modification the pointer 6 is given a uniform movement by an horizontally stretched wire wound on a shaft driven by clockwork mechanism. The Specification describes how some of the laws of mechanics may be verified by the use of the apparatus.

Patent GB-418226-A (GB)
Title: Improvements in the manufacture of textile materials
IPC: D04H3/16
Filed: 1933-04-21
Abstract: Bundles of continuous filaments are pre<PICT:0418226/IV/1> in a form suitable for stapling by blowing the travelling filaments in the direction of travel so as to separate individual filaments from one another, and winding the separated filaments so as to collect them in a state of substantial though incomplete parallelism.  Artificial filaments such as those of cellulose esters or ethers may be treated and collected continuously with their production.  The rate of winding is such that the filaments are wound with little or no tension.  The blowing nozzle may direct the filaments towards a part of the winding surface which is moving in a direction reverse to that in which the filaments are travelling.  Natural or artificial continuous filaments may be taken from bobbins, cheeses, or other packages.  They should have little or no twist.  As shown in the Figure, continuous artificial filaments 3 are taken from a dry spinning cell 4 round a roller 7, through a blowing device 11 to a collecting bobbin or reel 18. Adjustable tension rods 8, 9 also effect a preliminary separation of the filaments.  The blower 11 comprises an inner tube 13 through which the filaments pass, and an outer casing, air being forced through the annular space from a valve-controlled pipe 14. The mouth of the device 11 is flared and the filaments are spread out by the air current into a mass of separated filaments 17 which are received by the drum 18 at a point above its axis.  The drum rotates so that the filaments which have formed a loose pile are drawn downwardly.  It has flanges 19 to confine the filaments laterally.  It may be driven by cone and belt gearing and the speed may be controlled by means of a belt adjusting fork operated by handwheel and screw.  The peripheral speed of the drum is slightly less than that of the feed roller 7.  The bundle of filaments on the drum may be wetted with liquids containing hygroscopic substances to facilitate cutting by a guillotine or other device.  The preliminary separation effected by the rods 8 and 9 may be assisted by frictional electricity generated by the travelling filaments which tend to repel one another.  The effect may be increased by surfacing the rods with nonconducting material. Specifications 323,221, [Class 2 (ii)], 382,651, and 387,003, [both in Group IX], are referred to.

Title: Improvements in or relating to electric wave meters
IPC: G01R23/04
Filed: 1945-05-10
Abstract: 602,103. Coil-less resonators. STANDARD TELEPHONES & CABLES, Ltd., SMYTH, C. N., and WADE, A. S. May 10, 1945, No. 11724. [Class 40 (viii)] [Also in Group XXXVI] A wave meter comprises a hollow resonatorprovided with means controlled by the rotation of a cover which closes the resonator for adjusting its frequency, means for introducing. waves to be measured into the resonator, and means for detecting resonance. An annular brass casting 1 has cut in it a channel 2 also of rectangular section. A block 3 holds in position. a brass bar conductor 4 of square section formed into a ring coaxial with the channel 2 and centrally located therein so that it forms with the-channel 2 a coaxial conductor resonator. The casting 1 is supported by three metal legs 5. Sliding on the conductor 4 is a composite piston 6 having slots in which engages a fillet on the underside of an annular brass cover 16 which closes the channel 2 so that rotation of the cover causes the piston 6 to slide in the groove 2. Two separate resonators are thus formed, the lengths of which are adjusted simultaneously in opposite directions by rotation of the cover 16. These two resonators are terminated by opposite ends of the block 3 and by opposite ends of the piston 6. The cover 16 may be provided with graduations 17 marked in wavelengths and co-operating with an index mark 19. A coaxial transmission line 20 introduces the waves to be measured into one of the resonators. The central conductor of this line terminates in a loop 21 linking the field inside the resonator. A second transmission line may similarly introduce waves into the other resonator.

Title: Conforming of shoe uppers to the shapes of appropriate lasts
IPC: A43D21/16
Filed: 1971-04-28
Abstract: 1344740 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 28 April 1971 [30 April 1970] 11775/71 Heading A3B A pulling over and toe lasting machine includes a control lever 12 which moves as a consequence of the pulling movement of one of the grippers, the movement of the lever 12 and hence the gripper being limited by an adjustable stop 26, and means whereby an operator can disengage the control lever 12 from the stop and move the lever 12 further to allow the gripper to impart a greater tensioning movement to the upper. The machine includes a gripper controlled by a control lever 12 at each side of the shoe to allow the operator to correct the position of an upper on a last. As described a gripper 1, 2, 3 is carried by a piston rod 4 connected to a piston 6 in a cylinder 5, the gripper 1, 2, 3 being moved downwardly to tension the upper by supplying air under pressure through port 8 to the space above the piston 6. The space 13 below the piston 6 is filled with hydraulic fluid and is connected by line 57 to a cylinder 14 which contains a plunger 15. Thus downward movement of the piston 6 causes the plunger 15 to move to the left (as shown). The plunger 15 carries a cylinder 21 containing a piston 19 which is held against a bush 24 by air under high pressure supplied through port 23. The control lever 12 is pivoted at 32 to one arm 51 of a two armed lever 51, 17 which is pivoted to a shaft 18. The lever 17 has an abutment 52 in contact with piston rod 16. Thus movement of the piston 6 and hence the plunger 15 causes the lever to pivot about shaft 18 until it reaches a position 27 where it engages a stop 26. The stop 26 is adjustably mounted in a slot 29 in a bracket 28. If the operator is not satisfied with the position of the upper he can move the lever 12 transversely about pivot 32 to clear the stop 26 so that he can move the lever 12 further, e.g. to position 33, to allow further movement of the gripper. When the: pulling over is completed and the grippers have released the upper the cylinder 21 is connected to exhaust to allow the piston 19 to-move so thatthe grippers can be rapidly lowered out of the way of the wipers even though the lever 12 abuts the stop 26.
