Abstract: 996,618. Thermal switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 31, 1961 [Dec. 21, 1960], No. 43919/60. Heading H2B. A thermal time delay switching unit comprises two similar switches, the first of which is operated in response to movement of a bimetallic element heated by the passage of a current therethrough, said movement causing termination of the heating period, subsequent further movement of said bi-metallic element during a cooling period being utilized to operate the second switch. The first switch comprises a pivoted bimetallic strip 1 movable between stops 3, 4, and connected by a conducting spring 8, preferably a U-shaped leaf spring, to an insulatedly pivoted member 5 carrying a movable contact 7. Current is passed through a fixed contact 9 via strip 1 to a conductor 2, whereupon strip 1 curls towards stop 3 and spring 8 snaps member 5 over to move the contact 7 from fixed contact 9 to a stop 10, thereby breaking the circuit. As strip 1 cools in its new position, the straightening movement is transmitted via a rigid coupling member 11 to a compensating bimetallic strip 1<SP>1</SP> of the second switch, which is thus operated after a time delay due to the cooling period, movable contact 7<SP>1</SP> snapping over from fixed contact 9<SP>1</SP> to fixed contact 10<SP>1</SP>. A resetting arm 12 is used to return both strips 1, 1<SP>1</SP> of the two switches to their original positions.

Title: A centripetal plasticiser for substances of high viscosity
IPC: B29C48/47
Filed: 1966-10-05
Abstract: 1,144,669. Centripetal extrusion/injection moulding machines. H. PRUS. 5 Oct., 1966 [5 Oct., 1965], No. 44398/66. Heading B5A. A centripetal extrusion or injection moulding machine comprises a variable speed rotor 1 and two stators 2, 3 which are movable axially to vary the gap width h. The embodiment shown is an extruder comprising a mandrel 11 which defines with a nozzle tube 12 an annular extrusion path, the gap 13 of which may be adjusted by axial movement of mandrel 11. If intermittent extrusion is required, e.g. for blow moulding, the mandrel may be reciprocated by an hydraulic ram (not shown). Movement of stators 2, 3 is effected by admitting fluid from the same source via lines 20 to gaps 19. Pistons 18 are thereby axially moved each within a cylinder 15, 16, and the movement is transferred to stators 2, 3 via heat insulators 22. Stators 2, 3 and mandrel 11 are provided with devices 26 which may be preheaters, heaters or coolers, depending on the nature of the material being extruded. Temperature sensing elements 25 are also provided. Vanes 28 on rotor 1 facilitate the feed of powder or granules to the shear gap. In a second embodiment, Fig. 2 (not shown), tube 12 acts as an injection cylinder, being movable and terminating in an injection nozzle (29). Plasticized material enters cylinder 12 and the width h of the shear gap is narrowed to increase the pressure sufficiently to move cylinder 12 against the action of springs (30) and bring nozzle (29) into contact with mould (31) where the nozzle automatically opens. After injection the value of h is increased. Additional heaters (34, 35) are provided. In a third embodiment, Fig. 3 (not shown), the pressure for injection is supplemented by an hydraulic injection ram (36). Space (40) is filled by material passing between a ring valve (37) slidingly arranged on the inner surface of cylinder 12 and shoulder (37a) of ram (36) while h has a small value. Ram (36) is thereby moved rearwardly until contact is made with a switch (41) whereupon h is increased and ram (36) is moved forwardly bearing against ring (37) thereby interrupting the passage of further material to space (40). The consequent pressure increase causes cylinder 12 to move forwardly until nozzle (29) contacts mould (31).

Title: Improvements in data transmission arrangements
IPC: H04L27/10
Filed: 1962-11-23
Abstract: 1,018,605. Telegraphy. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Nov. 23, 1962 [Nov. 24, 1961], No. 44402/62. Heading H4P. In a frequency shift telegraph system the two frequencies required for transmission of binary data are derived from a single oscillator, and it is arranged that change from one frequency to the other takes place only when the signal has zero amplitude. At the receiver the frequency shift signals are converted to D.C. binary signals. At the transmitter, Fig. 3 (not shown), a square wave pulse train from astable unit BO is passed to bi-stable units B1, B2, B3. Gating circuitry P1-P4, controlled by data signals M, controls the manner in which B1-B3 treat the pulse train, and the arrangement is such that the output of B3 is one frequency for a mark and the other frequency for a space, these frequencies having the ratio 3: 2. The output of B3 is filtered to convert it to a substantially sinusoidal waveform and passed to line. At the receiver, Fig. 5 (not shown), the signals are filtered and limited and then differentiated by unit D, the output of which feeds bi-stable unit B<SP>1</SP>1. The rectangular signals from B<SP>1</SP>1 have the same form as the output of B3 at the transmitter, and are fed to two analysis channels comprising monostable (delay) circuits B<SP>1</SP>2-B<SP>1</SP>7. These circuits cooperate with gates P4-P6, which form coincidence circuits, and the channel units are such that one channel responds to mark frequency signals and the other to space frequency signals. Bi-stable unit B<SP>1</SP>9 thus provides signals corresponding to the original data signals M.

Abstract: 1529833 Repertory diallers SOPROGESPAR SOC DE PROMOTION ET DE GESTION DE PARTICIPATIONS 29 Oct 1975 [30 Oct 1974] 44770/75 Heading H4K A repertory dialler comprises a keyboard, which has both digital keys 1-0 and two function keys B, R, and a memory store 5 for receiving "dialled" digits and including a plurality of memory location registers (50, Fig. 6, not shown) each having a predetermined capacity. Each register may contain either one telephone number or two telephone numbers separated by a "pause" generated by depression of a function button. As shown, the housing of the dialler also carries a number display 821-8, a chosen register display 421-2 a "location in register" display 829, and three indicator lamps 1201 (green), 1202 (red) and 1203 (blue). Recording a number.-First a register is selected by "dialling" its number. The digits are coded at 2 into a 4-bit code and pass, via an anti-bounce circuit 3, to a memory address and display arrangement 4, Figs. 4 and 5 (not shown). Reception of the digits in this arrangement 4 causes a signal to be sent to the central programmer 11, Figs. 14A,B (not shown) which in turn causes the desired register to be accessed. The address of the register is thereby displayed at 421-2, the first number stored therein (if there is one) is displayed at 821-8, Fig. 9 (not shown), while, if there is more than one number stored in the accessed register a display "1" appears at 829. Key B is now depressed and the desired telephone number is "dialled" on the keyboard and appears on the display 821-8 digit-by-digit, as the previously-stored number is erased. A second number may be recorded in the same register by depressing B-to provide a pause or flag indication, indicated by "2" appearing at 829-and then "dialling" in the second number. Transmitting a recorded number.-The required address is selected as above resulting in the display of the number at 821-8. Key R is then depressed, handset 13 being left at rest. The programmer 11 actuates a tone detector 10 and when dialling tone is detected the stored digits are read out one-by-one to a number transmission control circuit 6, Fig. 7 (not shown) which controls the outpulsing of the digits to the line from a number transmitter 7, Fig. 8 (not shown). When all the digits have been transmitted the red lamp 1202 commences to blink. When the called party lifts his receiver, this is detected by an off-hook detector 9, which causes the green lamp 1201 also to blink. The hand-set is then lifted and the conversation may commence. A pre-selected time, e.g. 40 seconds, after handset 13 has been lifted the called number is extinguished from display 821-828 and is replaced by a continually changing display of the time elapsed since the hand-set was lifted. This display is derived from two counters (86, 87) included in the display circuitry. The indicator lamps 1201-3 indicate the state of the dialler and basically indicate: green (1201)-ON/OFF; blue (1203)-record; red (1202)-transmit.
