Patent GB-522344-A (GB)
Title: Tampon and method of and machine for forming it
IPC: A61F13/20
Filed: 1939-01-18
Abstract: 522,344. Tampons. DEHN, F. B. (Holly- Pax, Inc.). Jan. 18, 1939, No. 1778. [Class 81 (ii)] A rigid, self-retaining tampon of absorbent fibrous material is produced from a large approximately cylindrical tampon in dry condition by compressing it laterally by the simultaneous application of equal pressures to at least three circumferentially spaced areas extending substantially the full length of the tampon. Suitable apparatus comprises a base plate 11 upon which are mounted plates 13, 14 and 15 as shown. A central hollow shaft 23 is supported on a ball bearing 24 in the base plate and is journalled in plates 13 and 14. It is rotated by means of a gear 28 and pinion 29 connected to pulley 7 which is rotated by means of a belt 8. Spaced at equal angles and distances from the central shaft are five shafts 39 journalled in plates 13 and 14 and rotated by means of gears 34 from the gear 33 on the central shaft. These five shafts have a crank pin 39 at the upper end of each to which are connected by means of pitmans 40 the levers 42 pivoted at 43. These levers have shaped inner ends so that when the tampon is positioned between them the area over which the levers exert their pressure progressively diminishes with the volume of the tampon. The latter falls within the jaws when they are open from the conveyer 3 via the shute 4 and is compressed by the jaws. Simultaneously with the opening of the jaws the bar 57 is withdrawn by means of a pin 62 suitably positioned on one of the gears 34 and operating against the spring band 60, which engages the pin 58 on the bar which is returned by spring 61 on the further rotation of the gear. The tampon thus falls through the hollow shaft and is conveyed away. The pitmans 40 comprise an outer casing in which a spring is compressed by means of a collar screwed into its end and a collar threaded on the shaft which is pivoted to the levers 41. By rotating the shaft the spring can be more or less compressed thus adjusting the yielding stress of the pitman. This yield is necessary because the tampons are compressed to the limit of their compressibility and the interposition of a large tampon would result in the stalling or breakage of the machine. Specification 490,024 is referred to.
Patent GB-990905-A (GB)
Title: Improvements relating to roller mills
IPC: B02C4/42
Filed: 1964-01-15
Abstract: 990,905. Roller mills. AUTOMATIC STORAGE CO. Ltd. Jan. 15, 1964 [Feb. 6, 1963], No. 1808/64. Heading B2A. [Also in Division F2] A roller mill comprises a pair of rollers 16, 17 each having longitudinally-extending teeth, means to adjust one roller toward the other to a set desired position, with the teeth intermeshed or spaced, means to drive one roller 16, which in turn drives the other roller when the teeth are meshed, and a removable sprocket chain 40 for connecting the rollers and driving them when they are out of mesh. As described, the roll 17 is fastened to a shaft 23 which extends through slots 24 in side plates 11. The opposite ends of the shaft 23 are rotatably mounted in slide blocks 25, which can be adjusted back and forth in guideways 26. Threaded rods 29 are firmly connected to the slide blocks, which are urged forward by coil springs 31 and may be locked by nuts 30. Sprocket wheels 33, 34, serving as feed nuts, are threaded on the rods and interconnected by a chain 35, so that when the sprocket 34 is rotated by a handle it moves the rods 29 backward or forward and thus correctly positions the roll 17. The sprocket 33 is then locked by a nut 39, so that the roll 17 is locked against forward movement towards the roll 16 but is free to move back against the tension of the springs 31 to permit hard objects to pass. The rolls may be spaced, for grinding cobs, kernels &c., and the roll 16 is then driven by, and at a lower speed than, roll 17 via a chain 40 passing around larger and smaller sprocket wheels 22, 28. A chaintensioning arrangement 43, 41, 45 (see Division F2) may be swung away from and out of engagement with the chain to facilitate its removal and replacement. The apparatus may be used with a regulating gate and hopper (not shown) and with a breaking and shredding cylinder located directly above and driven in co-operation with the mill.

Abstract: 418,131. Hypodermic syringes. RIPPSTEIN, E., 127, Reinacherstrasse, Basle, Switzerland. Jan. 19, 1933, Nos. 1857 and 1859. Convention dates, Jan. 19, 1932 and July 5, 1932. [Class 81 (ii).] In a hypodermic syringe of the type comprising a holder having a depressible pressure rod and receiving a medicament container having fluid-tight packings at opposite ends, one adapted to be pierced by a needle, the other acting as a piston or plunger the front packing is provided with an elastic member, pressed between two interengaging parts so as to expand against the container wall, and has a narrow bore communicating with the interior of the container, its outer end being closed by a separate elastic sealing element adapted to be pierced by the needle. The syringe body may comprise a hinged portion pivoted to a cylindrical slide 5 which is slid forward by operation of a cap 7 to clamp the needle 15 in position as disclosed in Specification 407,109. The plunger comprises parts 26, 27 of artificial resin and a rubber block 29, the rod 28 screwing into the part 27 after traversing the other parts. The pressure rod 21 is formed with a claw 22 having a cavity 23 to receive a knob 24 on the rod 28, the distance between this knob and the rear wall of the cavity being such that, on depressing the rod 21, the claw exerts a pressure on the part 26 to ensure sealing of the plunger. The rod 28 may be threaded at the rear to receive a nut which bears against the part 26 so that sealing of the container can be effected during transport. The front packing comprises a member 30 on to which members 31, 32 are screwed. A rubber disc 34 is compressed between the part 30 and an offset portion of the member 31. A bore in the member 32 receives a rubber diaphragm 36 which is pierced by the needle. To prevent contact with the liquid prior to use a second diaphragm 37 may be used. By placing a washer between the parts 31, 32, the needle can be inserted without piercing the member 37. On removing the washer and screwing up the part 32, the tube is ready for use. The bore of the member 32 is extended to receive a thickening 38 surrounding the needle which abuts the diaphragm 36 and the syringe head. In a modification, Fig. 4, the plunger comprises two parts only, the member 29 being of rubber. The packing member 31 extends forwardly and is recessed at 41 to receive a projecting part, recessed at 42, of the elastic sealing element 36, against which element the needle disc 44 bears. The member 36 is made of slightly larger diameter than the interior of the syringe head.

Abstract: 1299541 Beam lead integrated circuits; assembing components WESTERN ELECTRIC CO Inc 15 Jan 1970 [21 Jan 1969 (2) 29 April 1969] 1998/70 Headings H1K and H1R A method of assembling an electrical component, e.g. a beam lead integrated circuit, in a predetermined position relative to external circuitry comprises providing co-operating ferromagnetic means in or affixed to the electrical component and the external circuitry such that the magnetic force exerted by the co-operating magnetic means serves to align the component in the predetermined position. The ferromagnetic means associated with the component may be in the leads or on the body of the component and may be in the form of a coating applied by, for example, sputtering, evaporating or plating or may be deposited during production of the component as an embedded layer. The ferromagnetic means associated with the external circuitry may be integral therewith or in the form of a coating. Alternatively, an electromagnet may be affixed to the circuitry in order to position the component and then removed. This method may be used to form temporary or permanent contacts between the component and the circuitry; if permanent contacts are required, the contacts are permanently bonded by, for example, laser welding. Magnetic means may be used to guide the component to its correct position by causing virtual movement of an electromagnetically generated field.

[Class 125 (ii)] Flat articles such as sealing caps or can ends are delivered singly from a stack in a magazine, the lower end of which is bent to assist in fanning out the articles and is provided with means for reducing the width of the magazine in one direction so as to impart an increased spacing to the articles. The stack magazine 18, Fig. 5, comprises a straight tube slightly inclined to the vertical, and fits flush into a block 15. At the right side of the axial plane A, the passage in the block is a continuation of the magazine. At the opposite side, the wall of the passage splays outwardly and is semicircular on each plane. Two pairs of blocks 22, 24 lying in planes parallel to the vertical plane through the axis A project from the walls of the block so as to provide a passage for the articles which narrows in one direction so that as the articles C pass towards the delivery opening they are tilted as shown. The bottom article lies on the surfaces 30 of a pusher slide 13, Fig. 6, which is formed rearwardly thereof with ledges 26 of less height. The distance between the outer edges 26<SP>1</SP> of the ledges is sufficient to accommodate the rim of an article C, and, in the case of a crown seal the top is accommodated between the edges 25<SP>1</SP>, the bottom 27 of the slide also being slightly hollowed out. The forward movement of the slide, to the right in Fig. 6. allows a cap to drop on the ledges 26. which terminate under the rear edge of the surfaces 30. On the backward movement, the cap drops on to the base plate, and a bevelled edge 32 on the surface separates the next cap from those above. The next succeeding right hand movement causes the curved end 31 of the slide to deliver the cap lying on the base plate. A block 35 fixed to the block 15 runs in the groove 36 of the slide and holds 'back the bottom cap during the rearward movement of the slide. The caps are delivered down a shoot 40, the front edge 41 of which is bevelled to give them an upward tilt and prevent them from falling edgewise down the shoot.
