Title: Controls for transducer drive on a telephone dialer
IPC: H04M1/276
Filed: 1963-03-04
Abstract: 1,032,436. Telephone dialer mechanisms. PERINI ELECTRONIC CORPORATION. March 4, 1963 [Dec. 31, 1962], No. 8477/63. Heading G5R. A motor 11 moves the transducer 22 against the force of a return spring 19, through a clutch which can be disengaged by a key mechanism and latched in the disengaged position until released by the return of the transducer. Construction.-As shown, Fig. 1, motor 11 drives shaft 13 through reduction gear-box 12. Clutch member 14, fixed to shaft 13, engages member 15 mounted on hub 16 which is free to rotate on shaft 13 and carries spring-spool 18 and chain sprocket 17. As shown in Fig. 3, transducer head 22 is mounted on carriage 23 which slides along two bars 24, 25. Endless chain 20 passes over chain sprocket 17 and idler sprocket 21 and is attached to carriage 23. Spring 19 wound on spring spool 18 has its free end 28 attached to the framework so that when clutch 14, 15 is released carriage 23 returns to the home position shown in Fig. 3. Key 30 actuates slidable bar 34, the end 35 of which operates clutch 14, 15. Bar 34 is latched forward by a spring-loaded latch 46 and thus holds clutch 14, 15 in its disengaged position. When carriage 23 returns to its home position it strikes and releases latch 46. Spring-loaded pawl 40 is mounted on bar 34 and engages ratchet wheel 39 the teeth of which operate button 38 of microswitch 37. Key 54 actuates pawl 40 to operate switch 37 without disengaging clutch 14, 15. Operation.-A broad magnetic tape with coded numbers on it is arranged below transducer head 22 and, after dialling a previous number, carriage 23 is stopped to the right of the home position. To dial the number recorded on the tape, key 30 is pressed. This releases clutch 14, 15 which is held open by latch 46 and spring 19 returns carriage 23 to its home position where it releases latch 46 which allows spring 48 to re-engage clutch 14, 15 and operate pawl 40 to step on ratchet wheel 39 to momentarily operate switch 37 which energizes motor 11 through a suitable circuit. The transducer head 22 is then driven across the tape until the recorded number has been dialled, when a circuit operates to stop the motor. Two-part numbers.-If the number to be transmitted consists of two parts, the motor is arranged to stop after dialling the first part. On receipt of dialling tone, key 54 can be pressed to re-energize the motor and dial the second part of the number without returning the carriage to its home position.

Abstract: 1461265 Coated plastics articles and apparatus for preparing them METAL BOX Ltd 17 May 1974 [24 Feb 1973] 9160/73 Headings B2E and B2L Plastics articles having a plurality of layers wherein adjacent layers are of materials which are substantially immiscible with one another, e.g. polyethylene and nylon or polypropylene and nylon, and are bonded by mechanical interlocking, e.g. as shown in Figure 7, substantially without adhesive bonding. A method of preparing such an article includes the steps of applying over a first primary layer of plastics material an intermediate layer consisting of a non-homogenous mixture of the first material with a second plastics material, applying a second primary layer of the second plastics material over the intermediate layer and applying heat while the. first primary layer is supported by a substrate or other support so that each of the layers is in a flowable state while the or eachnext adjacent layer is also in a flowable state and cooling so as to cause bonding of the first and second primary layers by mechanical interlocking. In a method of preparing flat sheets of material, three troughs or hoppers 30, 31, 32 are arranged below runway 33 from which is suspended for movement therealong, by cable 40 operated by motor 41, a support plate 34. Plate 34 is heated by element 35 via pickups 36 from wires 37 connected with source 38 and adjustable thermostat 39. Plate 34 is heated and held over each of the hoppers 30, 31, 32 while the associated electrode 42 is charged so that layers 15, 16 and 17 of plastics material are formed. The coated plate 44 is cooled by spray 44 to cause mechanical interlocking of layers 15, 16, 17. In an electrostatic spray method, support web 60 moves past nozzles 61, 62 of two electrostatic spray guns. Streams, of powder A, B of substantially immiscible materials overlap at spray zone 63. As heated web 60 passes through a first spray zone 64, a layer 15 of A only is formed and fused, layers 16 and 17 being formed by passage of web 60 through spray zones 65, 66. Subsequently the layers 15, 16, 17 are cooled and interlocked by water spray 44.  Flame spraying or fluidised bed coating methods may also be used. The support may form part of the final article which may be a wrapping material or a container. Coloured layers may be applied by this method. Further layers e.g. plastics layers, metal foil may be applied by conventional means such as adhesive.

Abstract: 1,140,043. Control systems for electricallyheated apparatus. SIEMENS ELECTROGER€TE G.m.b.H. 2 March, 1966 [2 March, 1965], No. 9241/66. Heading H2H. An electrically-heated device, e.g. a hotplate element 1, is controlled by a rectifier bridge 2 and semi-conductor controlled rectifier 3 whose firing instants (and hence the temperature of the element 1) are determined by the setting of the R.C. network 5 of a conventional oscillator 4, which is detuned by a resistor 6 to allow continuous energization of the element 1 up to a temperature in excess of the desired (set) temperature. When the excess temperature is reached, a voltage divider including a temperature sensitive resistor 8 causes firing of a semi-conductor controlled rectifier 7, which short-circuits the resistor 6 to allow the oscillator 4 to control the element 1 at a lower power level sufficient to maintain the desired temperature. Resistor 6 may be omitted and the capacitive part of the network 5 shorted out by the contact (10) of a relay (11) until the latter is energized at the excess temperature, Fig. 3 (not shown). The oscillator may be replaced by a transistorized phaseshifter (14) having part of its capacitance bridged by the semi-conductor rectifier 7, Fig. 4 (not shown), or having a resistor bridged by the relay contact, Fig. 5 (not shown), this last embodiment including protection against overheating in the form of two positive temperature coefficient resistors which operate at different temperatures to successively decrease the power. If a cold pot is applied to the element 1 when at its desired temperature, the supply may be temporarily interrupted, automatically or manually, to reset the control circuit and so permit continuous energization to be resumed.
