Title: Signalling apparatus
IPC: G08B17/00
Filed: 1974-10-11
Abstract: 1491222 Fire alarms C W MAXTED [TRADING AS PROTECTOR ALARMS (SALES)] 11 Oct 1974 44246/74 Heading G4N Signalling apparatus comprises a power supply circuit for supplying two output terminals and includes means for sensing a change in a circuit connected between said output terminals and a switching device controlled by said sensing means and operable for causing the power supply circuit to change from a first supply condition to a second supply condition (e.g. reversal of polarity) on such a change being sensed. A detection device is provided for connection between said two output terminals for producing the change in the circuit condition in response to an occurrence (e.g. fire) and including indicating means arranged to maintain its indication after resetting and an alarm signalling device for connection between said two output terminals to provide an alarm signal when the power supply circuit is in the second condition. As described, each detection device may be a smoke, flame or temperature detector or a FIRE switch of the "break-glass" type, connected in series with a diode poled so that it is responsive to the normal polarity of the power supply circuit. One or more audible or visible alarms is also connected across the two output terminals in series with a diode of opposite polarity. The two-wire circuit is also terminated in an asymmetrically conductive impedance so that the power supply circuit can give an indication of the continuity of the twowire line. In the normal condition of the power supply circuit (Fig. 7) relay 41 is not energized and connects terminals 3 and 4 respectively to positive and negative supplies via resistor 42. In the event of a fire, one of the sensors responds and the voltage developed across resistor 42 turns on transistor 44 which energizes relay 43 which, in turn, energizes relay 41 so as to reverse the polarity of output terminals 3, 4 and so cause operation of the alarm signalling devices connected via the two-wire line to terminals 3, 4. This action also holds the transistor conductive and produces a FIRE signal on line 49. A current limiting device 51 limits the current, and hence voltage, on the two-wire line connected to terminals 3, 4 during the change over condition. The circuit is reset by interrupting a negative line 55 so that the relays 41, 43 returns to their original state. In the event of a line fault, transistor 56 becomes turned on by the lack of current flowing in a Zener and conventional diode connected in series opposition at the remote end of the line and thus provides a fault signal at 59. Smoke detection.-Fig. 4 shows a smoke detector 15 connected across the two-wire line 5, 6. Under normal conditions 5 is positive with respect to 6, but when the sensor 15 responds, the power supply circuit (Fig. 7) reverses polarity. Diodes 28, 31 and transistor 32 now become conductive, providing the first polarity but of a lower voltage to the sensor 15. A local indicator lamp or LED 16, operated by a thyristor, is included.

Abstract: 1,169,353. Safety harness. NORRIS AUTO PRODUCTS Ltd. 20 Oct., 1966 [20 Oct., 1965], No. 44368/65. Heading A3V. A spring retraction reel in a vehicle safety harness is locked against rotation in the unwind direction by engagement of an inertia actuated pawl 96 with a tooth of a ratchet wheel 77 drivingly connected with the reel. The pawl is mounted on a rotatable shaft 86 and is rigidly connected to a tappet 98. Passing with clearance through a hole in the tappet is an inertia-sensitive device 20 the base 21 of which seats in a depression in the upper face of an arm 90 connected to the shaft 86. A member 25 may be provided integral with or separate from the upper end of the device 20; the sensitivity of the device may be varied by using members of different sizes. The device 20 tips over causing the tappet and thus the pawl to rotate and engage a tooth of the wheel 77 when the force acting on the device exceeds a predetermined value e.g. in sudden acceleration or deceleration or violent cornering. Once the force acting on the element 20 during normal travel of the vehicle has increased to said predetermined value where it moves the device 20 from its stable upright position, the force required to move the device further decreases as the angle through which the device has moved increases.

Abstract: 1,205,962. Calendar timepieces. HAMILTON WATCH CO. Oct.2, 1967 [Nov. 10, 1966], No.44820/67. Heading G3T. A setting mechansim for a calendar timepiece comprises detent means for holding a setting stem 26 in three positions in which the stem 26 is coupled respectively to (a) a setting wheel 64 (b) a date including means, such as a date ring 30 for setting the latter, (c) a dial train, including a minute wheel 94, for setting the hands of the timepiece. The detent means comprises a lever 86 carrying a follower 90 engaging and movable with the stem 26 to rotate the lever 86 about a pivot 88 between three positions in which it is held by the engagement of the tip 80 of a spring arm 78 with either or both of two pins 82, 84. A toothed clutch 60, slidable on and, rotatable with the stem 26, is engaged by a projection 72 on a lever 66 carrying the setting wheel 64 and biased by a spring 70 in a counter clockwise direction in Fig.3. The stem 26 is shown in Fig. 3 in its innermost position in which the toothed clutch 60 engages the setting wheel 64, and in which rotation of the stem 64 performs no other function in an electrically driven watch than rotate the members 26, 64, but the clutch 60 meshes with a ratchet wheel to drive the winding train in a spring driven watch. In the intermediate position of the stem 26 the setting wheel 64 engages both the toothed clutch 60 and the teeth 50 of the date ring 30 so that the latter may be adjusted by rotation of the stem 26; whilst in the outermost poisition of the stem 26 the setting wheel 64 engages both the toothed clutch 60 and the minute wheel 94 to enable the latter to be rotated to see the hands of the timepiece. As described in Specification 1,205,963 the date ring 30 is driven continuously by a pinion 112 integral with a triangular cam 114 and a staff 110, the cam 114 being engaged by a spring 118 secured to a toothed wheel 116 rotatable on the staff 110 and driven by the dial train. During setting of the date ring 30 by the stem 26 the pinion 112 and the cam 114 rotate relatively to the spring 118 and the wheel 116 so that the dial train is not affected. Alternatively the pinion 112 and the wheel 116 may be coupled by a slipping friction clutch. An apertured shutter 34 Fig.2 (not shown) rotates with the date ring and is advanced daily by cam mechanism to expose the appropirate date numeral.

When a signal indicating the end of an audio frame is detected the next video frame from the main magnetic tape is transferred to the magnetic loop for subsequent playback therefrom repeatedly with the associated audio information from the audio track of the main magnetic tape. In a second embodiment frames of the alternately received video and audio information are directly recorded on separate continuous loops of magnetic tape, each loop comprising a broad belt (or disc) for accommodating a large number of tracks with each track carrying a full frame of either video or audio information. During playback the audio belt is reduced in speed to provide audio narration over an extended time while the video belt operates at the recording speed and repeatedly provides the video frame signal to the television display. The programme selection from the transmittedinformation may be effected automatically by decoding networks which identify the desired frames. In the first embodiment the main magnetic tape cassette has four heads recording on four tracks, the video and audio frames being transmitted on two carriers with alternate video and audio signals on one carrier being recorded in two tracks and alternate video and audio signals on the other carrier being recorded in two further tracks, these latter video and audio signals preferably being transmitted in reverse order to accommodate reverse drive playback of the tape.
