Title: Apparatus for making cotton tipped swabs
IPC: A61F13/38
Filed: 1964-08-07
Abstract: 1, 048, 297. Apparatus for making swabs. CHESEBROUGH-POND's Ltd. July 21, 1965 [Aug. 7, 1964], No. 32353/64. Heading A5R. Swabs comprising sticks of a wood, paper, or a plastics material provided with a cotton tip at each end are formed in apparatus which includes a hopper 6 and a chute 7 used to supply the sticks to a carrier wheel where they are sprayed with adhesive from a nozzle 35 and rotated about their longitudinal axes so that lengths of cotton supplied from a conduit 36 become wound on the sticks. The swabs are then removed from the carrier wheel by a spring-loaded device 30 and passed to conveying members 41 which transport the swabs to a packing station, the members 41 being rotated non- uniformly about a wheel 44. The swabs may be removed from the packing station by a suction device. A pair of cylindrical brush rollers having a reciprocating rotatory motion feed the sticks from the shoot 7 to the carrier wheel, the shoot being vibrated by an eccentrically-mounted wheel 8. The carrier wheel comprises two spaced-apart wheels having peripheral formations 24 to receive the sticks, and an inner wheel with a surface of carborundum which rotates at twice the speed of the two outer wheels to impart the rotatory motion to the sticks. A plate 17 fits around the inner wheel and holds the sticks in position until they are removed from the wheel by the device 30. A pair of drums, one each side of the composite carrier wheel, are free to rotate and each has a peripheral groove which forms the cotton tip to the desired shape. The lengths of cotton are supplied through the conduit 36 by compressed air and are obtained from the mechanism described with reference to Figure 5 (not shown), which includes two pairs of driven rollers through which the cotton is passed, one pair of rollers being rotated intermittently to cause regular tears in the cotton. The swab-forming apparatus may also include a spring-loaded device 37 which aids in shaping the cotton tips.

Abstract: 1,157,961. Electric selective signalling. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. 20 July, 1966 [28 July, 1965], No. 32356/65. Heading G4H. A recording system for aircraft comprises a first magnetic recorder for recording data usable for establishing conditions preceding a crash, a second magnetic recorder on which the same data and additional data may be recorded, normalizing means to convert the outputs of a plurality of transducers to equivalent analogue voltages, each analogue voltage then being selected in turn and digitized prior to recording in serial form in the first recorder and in parallel form in the second recorder. The first and second recorders are magnetic wire and magnetic tape recorders respectively and the tape is readily removable to allow flight parameters, engine efficiency, &c. to be ascertained after a routine flight. The data items recorded on the tape in one second say are in the sequence where C is an item for crash diagnosis and A is an additional item. The data items recorded on the wire in one second are in the sequence where C is as before and B is a blank position. Four items are recorded across the width of the tape, longitudinally displaced along the tape from each other. Marks in four additional tracks enable the items to be identified. Parity bits are generated.

Title: Improvements in rolling mills
IPC: B21B37/66
Filed: 1963-08-16
Abstract: 1,020,775. Rolling. F. MOELLER and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER & NEUMANN OFFERE HANDELSGESELLSCHAFT]. Aug. 16, 1963 [Aug. 29, 1962], No. 32501/63. Heading B3M. A method for removing the effect of non- circular rolls in hot or cold sheet and strip rolling mills includes applying a signal which is proportional to the respective algebraic sum of the non-circularity of the rolls, to means for adjusting the roll gap so that changes in the gap due to non-circularity are avoided. As shown, back-up rolls 16 and 17 of a mill having attached coaxially to them discs 35 and 36 which have been previously prepared to indicate in an exaggerated form the error in circularity of the rolls. Roller followers 37b and 38b bear on the discs to actuate differential transformers 37 and 38, electrical signals being passed to a device 46 for forming their algebraic sum. The signal passes to an amplifier 47, a compensator 49, and to a controller 14 which actuates the valve 10 of a pressure transmitter 8 to vary the hydraulic pressure acting on cylinders 4, thus altering the roll gap. The frame is initially prestressed by means of pistons 4, a pressure measuring device 5 sending a signal to the controller 14 corresponding to the rolling pressure. The non-circularity control can thus be additional to conventional roll pass control which depends on the roll pressure. Instead of profiled discs 35 serving as signal sources the roll profiles can be drawn on discs or may be fed on to tapes or film strips, the resulting source being scanned electrically, magnetically or optically.

Title: Method for connecting two members by a shrunk fit
IPC: B23P11/02
Filed: 1959-09-24
Abstract: 896,899. Jointing; assembling force fits. LIPS N.V. Sept. 24, 1959 [Sept. 27, 1958], No. 32567/59. Class 83 (4). A method of making a shrunk fit connection between two members made of metal or of other structural material whose rigidity and elasticity are similar to those of metal, comprises first changing the diameter or corresponding dimensions of at least one of the members in a direction tending to reduce interference between them, by applying an external tensile or compressive force to said member in a direction transverse to the direction of the dimension to be changed, then inserting one member into the other to effect the connection whilst maintaining the externally-applied force and thereafter removing the applied force. In an embodiment for mounting a sleeve on a shaft the sleeve is compressed by tensioning elements extending on the outside thereof and parallel to the axis of the sleeve, said tensioning elements, e.g. bolts, pulling together two flanges removably mounted on each end of the sleeve. The shaft is then inserted in the sleeve and the tensioning elements released to allow the sleeve to shrink on to the shaft. An externally applied force may be exerted simultaneously on each member, for example a tensile force on the inner member and a compression force on the outer member.

Title: Improvements in and relating to machines for forming sector-shaped prismatic containers and filling them with plastic substances
IPC: B21D51/26
Filed: 1937-11-27
Abstract: 492,490. Making and filling packets. KUSTNER FRERES & CIE SOC. ANON. Nov. 27, 1937, No. 32792. Convention date, Nov. 27, 1936. [Classes 18 and 94 (i)] Wrappers or blanks of the form shown in Fig. 1 are formed into containers of sector-shaped prismatic form with one horizontally disposed side open as shown in Fig. 3. The container is filled in the direction of the arrow 11 and the open side closed to complete the packet. The blank has a rectangular panel 7 flanked by two portions with circular edges 4 and straight edges 1, 2. The formation of the container is effected by a two-part die 20, 21, Fig. 4, co-operating with a matrix. The panel 7 is engaged by a flat side 22 of the part 20, which descends vertically into the matrix and forms the sides 9 and the lower part of the curved side 10. Enlargements 25 on the part 20 splay the edges 12, 13 to facilitate the subsequent filling. Simultaneously, the part 14 is drawn inwards to a vertical position. Continued descent of the bracket 31 carrying the die causes the spring mounting 34 of the part 20 to be compressed, and a link 35 moves the part 21 downwards in a direction parallel to the side 22. This completes the side 10, and the extensions 15 are folded inwards on to the part 37 of the die by a resilient arm. The die is withdrawn in the reverse order to that of its entry, the part 21 first sliding on the surface 28, and the whole subsequently rising vertically out of the container. The container is then filled and the open side closed in the order 14, 15, 12, 13. In order to prevent the filling apparatus from operating if no container is present in the carrier, a feeler is arranged to pass into an aperture in the carrier, unless prevented by the wall of the container, and to stop the feed of the material.

Filed: 1964-08-13
Abstract: 1,036,657. Matching impedances; transformers. TEKTRONIX Inc. Aug. 13, 1964 [Aug. 15, 1963], No. 33045/64. Headings HIT and H1W. An impedance transforming arrangement comprises a main magnetic core 72, of e.g. ferrite, carrying a primary winding 71 and a number of secondary windings, e.g. 76, 78, 80, 82, the secondary windings being connected together in series by short-circuits, e.g. 84, 86, 88, reflection of signals from the short-circuits back to the core 72 being delayed by interposition of isolating cores 90, 92, 94, 95, of e.g. ferrite, each positioned about the opposite ends of a different secondary winding, e.g. core 90 is positioned about the opposite ends 76, 76<SP>1</SP> of the first winding. In the example shown, the arrangement provides impedance transformation between a 25 # coaxial line 68 connected to the primary winding 71 and a 100 # coaxial cable 74 which is connected to a first end, e.g. 76, of one of the secondary windings and a second end, e.g. 78<SP>1</SP>, of one of the other secondary windings. A fifth isolation core may be positioned about the ends 76, 78<SP>1</SP>. A step junction 98 applied to the primary winding produces at opposite ends of each secondary winding, e.g. in ends 82, 82<SP>1</SP>, opposite signals of the form shown having amplitudes equal to three times the amplitude of the original step function and a rise time equal to three times the delay of a secondary winding turn (there are three turns per winding). Because of the short circuits, these signals are combined to produce in the line 74 a signal having an amplitude twenty-four times the amplitude of the original signal and a rise time equal to three times the delay of a secondary winding turn. The steps shown are absent in the actual signal which has a smoothly rising characteristic. The isolation cores, in delaying reflections back from the short-circuits until after the push-pull signals in the ends of the windings have been added, prevent the main transformer from seeing a short-circuited output. Whilst the pulses are added, the transformer sees, in effect, a push-pull output. Similarly, an extra core around ends 76, 781 prevents the transformer from seeing the grounded termination of end 78<SP>1</SP>. Two other embodiments having different members of windings and turns per winding are described.
