Abstract: 1,063,049. Alarm systems. SIOC Ltd. Aug. 4, 1964 [Aug. 1, 1963], No. 31311/64. Headings G4F and G4N. [Also in Division H3] In an alarm system, an, electroluminescent panel is supplied with power from an A.C. source via a controlled rectifier. The occurrence of an abnormal condition causes transistor 24 to become conductive and the change in emitter potential is differentiated by capacitor 36 and resistor 38 to produce a pulse which switches crosscoupled transistors 40, 54 to their conducting state to supply power to transistor 60. Transistors 60 and a normally non- conducting transistor 62 form a multivibrator 18 which now starts to oscillate causing transistors .62, 74 and controlled rectifier 16 to periodically switch on and off connecting supply 14 periodically to electroluminescent panel 12, causing it to flash. An audible alarm 48 is also sounded. Opening switch 48 stops the audible alarm and switches-off transistors 40, 54 and the multivibrator 18 stops oscillating with transistor 62 held conducting by a potential fed from the emitter of transistor 24 via diode 90 and resistor 88. The electroluminescent panel 12 is thus steadily illuminated. A switch 46 is provided so that the alarm indication may cease at the termination of the abnormal condition, or may be maintained until reset.

Abstract: 1383206 Lubricating GRAPHOIDAL DEVELOPMENTS Ltd 6 July 1972 [7 July 1971] 32010/71 Heading F2A A lubricating system which dispenses metered quantities of lubricant (e.g. an aqueous dispersion of colloidal graphite) has a lubricant reservoir 10 which feeds a charge chamber 12 via a supply line 14 which is controlled by a valve 24. Means are provided for pressurizing the charge chamber so that the metered quantity of lubricant can be discharged therefrom and the arrangement is such that after the discharge some of the residual pressurized gas in the charge chamber escapes via the valve 24 back into the reservoir so as to agitate the lubricant therein thereby counteracting the tendency of the system to become blocked. The charge chamber is a closed container and a return line 16 is provided from the chamber to the reservoir to promote flow of lubricant. The return line is controlled by a valve 26 which is similar to the valve 24 in the supply line 14. As described the valves 24 and 26 close in response to an increase in pressure in the air line 32. The air line also communicates with the charge chamber so as to pressurize the lubricant therein after opening a valve 30 against a spring bias. The air line further operates a valve 38 which opens the exit from the charge chamber so as to permit discharge under pressure of the metered quantity of lubricant.The lubricant may be injected into a stream of compressed air so as to form a spray. The valves 38, 40 which control the discharge of lubricant and the compressed air line may be arranged to operate slightly after the charge chamber has been pressurized. On reduction of the pressure in the air line the valves 30, 38 and 40 are closed and the valves 24 and 26 opened whereby the residual pressure in the charge chamber passes through the return and supply lines to agitate the lubricant in the reservoir. Means are provided for regulation of the flow and pressure in the air line and also for holding the valves 38 and 40 open so as to permit flushing of the system with water. Reference has been directed by the Comptroller to Specification 1,139,791.

Abstract: 853,527. Tufting machines. CARD, J. L. Oct. 9, 1958, No. 32272/58. Class 112 In a multi-needle tufting machine the needle bars are selectively locked to and released from a common needle bar carrier for producing skipped stitches in accordance with a predetermined pattern. A horizontal needle bar carrier 18, vertically reciprocated from a driving shaft 11 via eccentrics 17, eccentric straps 19 and rods 20, has slidably mounted therein a plurality of needle bars 21 each of which carries a needle 22. Each needle bar is normally fixed to the carrier by a slidable locking pin 43 which is biased by a spring 45 to engage a nose 46 thereon with a notch 47 in the needle bar. Pin 43 is connected by a rod 48 and bell crank levers 49, 52 to the armature 56 of a solenoid 55.. Energisation of the latter thereby serves to free the needle bar, when a spring 57 moves the latter to its uppermost position in contact with a fixed stop 63. Spring 57 is fixed at one end to the presser foot 58 and its other end 61, which encircles the needle, serves to clamp the yarn 59 against the lower end of the needle bar when the latter is raised. It is stated that spring. 57 may be alternatively arranged to clamp the yarn against the needle. In a modification pin 43 is directly connected by a rod to the armature of a solenoid. Energisation of the solenoids is controlled by a pattern drum 65 fixed to a rotary shaft 67 and carrying a pattern sheet 66 formed with spaced slots 79. When the nose of a pivoted finger 77, biased into engagement with the pattern sheet by a spring 78; enters a slot 79, the tail 80 closes a contact 81 in the circuit of its associated solenoid to energise the latter. Specifications 780,370 and 853,528 are referred to.
