Title: Pim insertion device
IPC: H05K13/04
Filed: 1972-01-25
Abstract: 1362085 Discharging articles from an orderly arrangement HONEYWELL INFORMATION SYSTEMS Inc 25 Jan 1972 [11 March 1971] 3516/72 Heading B8S [Also in Division B3] A pin insertion device comprises a hopper 14 having a forward wall 19 with a plurality of ports 20 at the base of the wall for the passage of pins 11 therethrough, a plurality of spaced, parallel partitions 16 mounted in the hopper, and a pusher 31 which is positioned adjacent one end of each pin lying in the bottom of the hopper, the pusher being movable towards the wall to move each pin on the hopper bottom 26 through a corresponding port. The forward wall is pivotally mounted by a pivot rod 21 to side walls 24a, 24b and a spring 22 causes a roller 23 to bias the forward wall, Fig. 3 (not shown). A vibrating trough 10 supplies a plurality of pins to the hopper which are then aligned by the partitions 16 into spaces (17), Fig. 6 (not shown), the distance between the partitions being slightly greater than the width of individual pins but substantially less than twice their width. The pusher is moved by a push rod 32, Fig. 1, and the edge of the pusher makes contact with the bevelled lower edge 42a of the partitions causing the latter to pivot about rod 21. A groove in the edge of the pusher is designed to mate with the end of a pin 11a, Fig. 4, to prevent it from moving upwardly as the pusher moves the pin through a corresponding port. Continual movement of the pusher forces the pins into a circuit board (not shown) positioned beyond the forward wall. A pair of guides 40a, 40b can be used to correctly position the board near the hopper for receiving the pins whose ends may be slightly pointed to facilitate insertion. A barrier may be placed across some of the spaces 17 so that pins do not fall into these spaces. In an alternative embodiment guides 40a, 40b, spring 22 and roller 23 may be removed so that the board can be placed directly against forward wall 19 of the hopper although this lowers the devices' operating speed. The device can also be used to load a plurality of pins into a magazine to be used in pin insertion machines of various types and used to load pins into an insertion head which then inserts the pins into circuit boards.

Patent GB-344170-A (GB)
Title: Improvements in the manufacture of films
IPC: C08L1/12
Filed: 1930-02-04
Abstract: <PICT:0344170/IV/1> <PICT:0344170/IV/2> In the manufacture of cellulose ester films by spreading solution on a supporting surface, coagulating the solution by immersion in a liquid or vapour such as steam, and then stripping the wet film from the supporting surface, the film is subjected in the wet and semi-plastic or swollen condition to a stretching operation and is dried while under tension so as to avoid or overcome the tendency to shrink usually encountered in such processes.  Films which have been dried and are partially shrunk may be treated with a swelling agent such as acetone and water and then stretched and dried under tension sufficient to maintain the initial stretch.  The treatment may be applied to cellulose acetate films obtained with the aid of a high-boiling point non-solvent as coagulating agent such as diamyl-phthalate, dibutyl phthalate, amyl benzoate, ethylene glycol, tricresyl phosphate and monochloro-naphthalene, or to cellulose nitrate films obtained by coagulation in steam or water vapour.  The force used for stretching should in general be such as to produce a 10 per cent and upwards elongation of the film. Films thus treated do not shrink after drying and show very little tendency to elongate when soaked in water.  The films may be treated in the form of a continuous strip or in separate sheets. In Fig. 1, a sheet of film 11 is clipped to a frame 5 which may be supported in a drying chamber.  The lower edge of the strip is clipped to a frame 7 which is loaded with a weight 9 adjusted to stretch the film to the desired extent.  The film remains suspended under tension until it is dry.  In Fig. 2, a continuous strip of film 11, which after coagulation on a support such as a drum has passed through a washing solution, passes into a drying compartment and around rolls 21, carried in a suspended frame 19 loaded with a weight 22, and around rolls 18 carried in a fixed frame 16A.  The film is thus stretched and dried while under tension.  A film which has been dried before the treatment may be passed through a bath containing a swelling agent and then through the stretching apparatus.  In another construction, the swollen film is drawn over a number of drying rolls which revolve at a greater speed than the feed rolls so as to stretch the film.

Filed: 1975-01-30
Abstract: 1470466 Inductive arrangements ITT CREED Ltd 30 Jan 1975 4088/75 Heading H4P and HIT [Also in Division H4] A telegraphic isolating arrangement comprises a magnetic circuit having two similar paths each with an air gap and magnetizable equally and oppositely with a means for differentially changing the flux according to direction of line current, with a flux sensor in each air gap respectively arranged to allow passage of impulse trains from a common generator to output terminals when flux in one gap is reduced. The magnetic circuit is basically of "E" configuration with a central permanent magnet 12 inducing the flux equally and oppositely in limbs 8, 9. In gaps 2, 4 are saturable square loop ring ring limbs 13, 14 having a common primary winding 15 connected to a pulse generator 16 and separate secondary windings 17, 18. Permanent magnet 12 normally just saturates ring cores 13, 14 hence pulses from generator 16 not causing any substantial desaturation of the cores, are not induced in windings 17, 18 pulses. A current through windings 8, 9 however will unsaturate one path hence pulses, the frequency of which are large relative to the speed of incoming signals, will appear on terminals 17, 18. For a signalling speed of 50 bauds a pulse repetition rate of 1 MHz is proposed to provide a number of output pulses in with badly distorted signals, such repetition rate also permitting use of very few turns i.e. one or two in both primary and secondary windings on the core. An alternative configuration is shown in Fig. 2, having two permanent magnets (37, 38) with winding 34 connected to the telegraph line.
