Title: Electronic apparatus for the permanent storage and automatic dialing of telephone numbers
IPC: H04M1/27495
Filed: 1975-05-19
Abstract: 1509285 Repertory diallers STOPPANI SA 19 May 1975 [20 May 1974] 21257/75 Heading H4K A repertory dialler includes the following features: (a) A memory circuit 900 comprising a plurality of storage sectors, each including a plurality of storage cells. Each cell is capable of storing one item of digital information, e.g. a digit of a telephone number. More than one telephone number may be stored in each sector, different numbers being separated by a "pause" indication. (b) A keyboard 22 for writing data into the memory, retrieving stored data therefrom, and for commanding the various operations which may be performed on the data. (c) The pause button P of the keyboard provides a "rapid scan" facility when data is being retrieved from the memory. Thus, if a third number stored in a given sector is required to be dialled out, the first two numbers are ignored by manipulation of the P button. Storing a telephone number.-A vacant sector is selected by keying in the appropriate sector number, which then appears as a luminous display at 23. Next, the key MEM is depressed, which causes the number at 23 to blink. The telephone number, which may include a pause, e.g. after an initial "O" if desired, is then keyed in. As each digit is entered, it appears as a luminous display in the indicator 26. When the number has been composed, it is transferred from a buffer memory (910, Fig. 9, not shown) to the memory circuit (901) by a second depression of MEM.  Dialling a stored number.-The desired sector is selected as above. The key CALL is then depressed, resulting in looping of the associated telephone line. At this stage the handset of the associated telephone set does not have to be lifted. On hearing dialling tone from a loud-speaker 25, CALL is released and a transmission device 100 outpulses the appropriate digits to the line. Special conditions.-Normally, most, if not all, sectors will be subject to an inhibition, supervised by a surveillance circuit 800, whereby a recorded telephone number cannot be erased and replaced by another. However, certain privileged personnel may be provided with a code key 33 which, when inserted into the apparatus, modifies the circuitry of the general control 400 so as to remove the inhibition. Other inhibitions that may be provided, removable only by use of a code key, are: (a) No telephone numbers with more than a pre-set number of digits may be stored. (b) Certain initial digits, or combinations thereof, may be forbidden. Circuitry.-Details of the circuitry of the eight functional units shown in Fig. 2 are given, Figs. 4-11 (not shown). Preferably each unit is in the form of an integrated circuit board employing large scale integration (LSI). Alternatively, circuits of the TTL and/or CMOS type could be used.

Patent GB-654783-A (GB)
Title: Improvements in or relating to the manufacture of continuous films or sheets of regenerated cellulose
IPC: B29D7/00
Filed: 1948-08-17
Abstract: <PICT:0654783/IV (a)/1> <PICT:0654783/IV (a)/2> <PICT:0654783/IV (a)/3> Viscose solution is extruded from a pair of separate extruding nozzles into coagulating liquid so as to form a pair of films or sheets, both sides of each film being brought into contact with the liquid until the film surface becomes non-tacky, and the films are then brought together in surface contact and are fed together through a treating liquid with only one side of each exposed until the treatment is completed; the films are then separated and passed through separate drying zones.  The nozzles may feed into the same or separate coagulating baths.  If desired, two or more pairs of nozzles may be employed to form several pairs of films which are treated so that only one surface of each film is exposed to the treating liquid. As shown in Fig. 1, a pair of extrusion nozzles 1 and 2 extrude viscose into baths 3, 4 and the regenerated cellulose films 7, 8 are brought into contact at a guide 11.  They are then passed with only one surface of each exposed, through baths 15 for washing, desulphurizing, bleaching, and softening.  They are passed over upper and lower guides 19. After emerging from the baths, the films are separated and passed over separate series of heating and drying rolls 20, 21, and they are then wound up separately.  As shown in Fig. 2, four films are treated in pairs so that one surface of each is exposed to the treating liquid.  Two nozzles 30 are arranged to extrude viscose into each of two coagulating baths 32.  The coagulated films 35 are brought together in pairs and then fed through treating baths 38.  The four films are fed together over bottom guides 40 but the pairs of films are passed over separate upper guides 41, 42. Guides 42 are of larger diameter so that the pairs of films are separated in baths 38 and one surface of each web is exposed to the treating liquid.  Instead of large guides 42, pairs of guides 43, Fig. 3, may be used.  After emerging from the final liquid treating bath the four films are separated and passed over separate sets of drying rolls.  By bringing the films together for the liquid treatment there is less danger of breakage and crinkling.

Title: Improvements in and relating to locks for doors and the like
IPC: E05B63/20
Filed: 1948-08-20
Abstract: 641,335. Night latches. THORNE, H. Aug. 20, 1948, Nos. 21958/48. and 6591/49. [Class 44] A night latch comprises a spring urged bolt and a cam track associated therewith in which rides a detent caused to move round the track in the same direction, successively to retain the bolt in a half-shot position and to allow it to be fully shot. In the form of Figs. 1 and 2 the bolt 5 is formed with a part 6 of box form in which is a horizontal plate 28 carrying a U-shaped member 27 and a blade spring 26 the end 26<1> of which is free. The detent is formed on the end of a rod 13 having a vertical limb pivoted at 14 to the casing 1 and an arm 12 to which is attached a spring 9. The free end 25 of the wire is adapted to cooperate with the notch 27 and the spring 26 to control motion of the bolt as follows. In the fully shot position (shown) the detent lies over the end of the' blade spring 26 and, when the bolt is retracted by an outside 'key lock 30 or an inside sliding handle 19, slides up and falls on a pin 29 projecting from the bolt. When the handle is released the detent engages in the notch 27 to hold the bolt in the half shot position (shown in dotted lines). When the door is slammed the bolt is pressed in by the rounded nose 16 engaging the edge of the keeper, and this movement allows the detent to pass out of the notch and slide back along the inner face of the box 6, passing under the free end of the blade spring 26 into the initial position. The bolt may be formed with rounded surfaces on each side to suit right- or left-handed doors. The handle spindle 18 passes along a slot 20 in the casing and may deadlock the bolt in the fully shot position by engagement in one of the side slots 21. The spring 9 is attached at 15 to the box 6 and serves to shoot the bolt. The outside key lock 30 carries a follower 32 engaging a plate 33 to retract the bolt. In the form of Fig. 4. a detent arm 43 pivoted to the casing carries a pin 44 riding in a cam slot 45 formed between an opening in the bolt plate and a body 48, part 49 of which is pivoted at 50 to provide a non-return gate ensuring that the pin always passes round the cam slot in the same direction. The action is similar to the form above, the pin being received in the slot 46 in the fully shot position of the bolt and in the notch 47 in the half shot position. A deadlocking pawl 59 engaging in a notch 60 is released by the initial movement of the key lock follower 61 before it engages the abutment 37 to retract the bolt.

Title: Improvements in or relating to preforming presses
IPC: B29C43/00
Filed: 1958-07-09
Abstract: 833,969. Preforming presses. KORSCH, E., KORSCH, H., and KORSCH, G., [trading as KORSCH SPEZIALFABRIK FUR KOMPRIMIERMASCHINEN, E.]. July 9, 1958 [July 12, 1957], No. 22099/58. Class 87(2). The cavity 13 of a compression mould communicates by means of a compression space 6 tapering away from it with a screw casing 1 in which are mounted one or more conveyer screws 2, 3 by means of which the material to be moulded is fed from hopper 1<SP>1</SP> and precompressed during the feeding operation, actuating means responsive to the pressure in the compression space being provided for setting into operation the drive for the mould dies 20, 21. Actuating means are also provided to stop the conveyer screw drive when the desired precompression has been reached. In the initial position of the dies, Fig. 1, the contact switches 43, 44 are actuated, switch 43 breaking the circuit to a magnetic clutch 11 which sets the conveyer screws 2, 3 into operation and switch 44 breaking the circuit to a magnetic clutch 45 (see below). The screws mounted on bearing bush 46 are first moved forward by the compression spring 38 until the precompression is such as to force them backwards against the action of the spring to actuate contact switches 41, 42. Switch 41 breaks the circuit to a magnetic clutch 12 which stops the screws and switch 42 completes the circuit to magnetic clutch 45. Clutch 45 causes movement of a crankshaft 26 which on rotation causes the collapse and extension of the toggle lever system 22 operating the die presses 20, 21. The compression space 6 may be connected with the mould cavity as shown or may connect with a cavity provided in a slide member or rotary table, the preliminarily pressed material being fed to the dies by a forward or rotary movement. The precompression may be governed by an adjustable torque clutch 121 or a continuously variable gearing 8 having a series-connected planet wheel gear 9. In the event of rapid successive movements of the press dies, the drive to the conveyer screws may be continuous. This press is particularly suitable for the moulding of material which may or may not include filling substances which are flocculent or comprise long fibres, or which may consist of flocculent or long-fibred substances or of moist, paste-like materials, to be moulded in tablet form.
