Title: Alarm systems
IPC: G08B25/00
Filed: 1971-12-30
Abstract: 1381734 Alarm systems BALDWIN ELECTRONICS Inc 30 Dec 1971 [31 Dec 1970] 60832/71 Heading G4H In a radio alarm system comprising a central station and plurality of peripheral stations, detection of an alarm condition at a peripheral station causes it to generate a pulse train representing a sequence of substantially identical frames of data following one another without pause, each frame commencing and terminating with identical master pulses of width different from the other pulses in the train, the commencing master pulse of each succeeding frame being constituted by the terminating master pulse of the preceding frame, there being between the master pulses of a given frame a fixed predetermined number of data pulses some at least of which are modulated in time position to constitute a multi-digit coded number identifying the peripheral station, the sequence of frames being transmitted by radio to the central station wherein the data is received, decoded and stored. As disclosed, there are four data pulses per frame, the time interval between the (leading edge of the) commencing master pulse and the first data pulse identifying one of ten alarm detectors at the peripheral station, and that between the first data pulse and the second, that between the second and the third, that between the third and the fourth and that between the fourth and the terminating master pulse specifying the four decimal digits of the peripheral station identity respectively. Each alarm detector includes a bi-stable which is set by the alarm condition and can be reset manually or after 3 minutes, provided the alarm condition has been remedied, the use of the bistable preventing repeated outputs from an alarm detector for the same alarm condition. An output from any of the ten alarm detectors at the peripheral station turns on the power supply to the rest of the station for 3 minutes, and keys on a transmitter for 6 periods of 10 seconds, separated by 20-second gaps, the frame being sent 10 times per 10-second period. A decoded count is used to sample a resistor in the alarm detector followed by four further resistors, the five resistors providing amplitudesignificant voltages which by means of an integrator and thresholder produce timed pulses constituting the frame pulses. An oscillator provides one frequency for pulses and another for gaps between pulses, the frequencies passing to the transmitter via a modulator. Two lamps at the peripheral station indicate " at least one detector on " and " all detectors off" respectively. At the central station, the five intervals in the frame are measured by counting clock pulses, six counters being provided, two of these being used alternately for the first interval of successive frames. The counts are stored, displayed on lamps and printed out. An audible alarm can be given if several data frames (i.e. from different peripheral stations) are coupled to the lamps together. A test is possible by feeding the clock pulses to a series arrangement of the counters for one second, a visual check being made of the counts displayed.

Patent GB-615321-A (GB)
IPC: B03B5/24
Abstract: 615,321. Automatic level control systems. TENNESSEE COAL, IRON & RAILROAD CO. 11, Oct. 1945, No. 26550. Convention date, March 6. [Class 38 (iv)] [Also in Group II]  In a jig for cleaning or separating materials such as coal in which a stratification of material is effected by water pulsations through a grid, automatic control of the feed is effected by a float " resting on the lower (heavy) stratum in conjunction with a system of switches controlling an electric motor which operates to raise or lower a gate at the material inlet. Further provision is made for similarly closing the discharge valve for the heavy stratum when the latter falls below a predetermined level. In the arrangement shown, to ensure a constant level of the " rock " (heavy) layer R for efficient working, a suitably weighted " float " 111 resting thereon is arranged to close one or other of a series of switches FL1, FL2 ... (Fig. 5) in its vertical up or down movement. This in turn energizes a relay 1L, 2L ... and one coil (136 or 147, see Fig. 10) of the reversing'contactor RC, and allows current from a supply L1, L2, L3 to pass to a motor 70 via one of the switches 1D, 2D ... in the "limiting box " 77. The motor then rotates the screw 73, 80 and through the agency of the nut 82, as in 88 and frame 68, raises or lowers the gate 66 and at the same time also raises or lowers the arm 94 (see Fig. 6). The switches are so arranged that a rise in level of the layer R lowers the gate 66, and vice versa; while the motor is stopped when one of the switches 1D, 2D ... or 1U, 2U opens due to the motion of the arm 94 and its associated fingers 100, 101 ... , thus breaking the relay 1L, 2L ... circuit, to de-energize the contactor RC and cut the motor circuit. Should the level R fall below that allowed for by the positioning of switches FR1 and FR2, the contact FVC (Fig. 5) is made, which operates the relay VC and energizes the coil 248 (Figs. 1 and 9) so attracting the pawl 256 to prevent rotation of the discharge valve 34 and so allow the layer R to build up. U.S.A. Specifications 997,609, 1,077,876 and 1,327,537 are referred to.

Title: Supporting deflated tyres
IPC: B60C17/06
Filed: 1978-11-27
Abstract: An annular insert 10 is composed at least in part of a closed cell resilient material and in use fits about a wheel rim within a pneumatic tyre 30. The insert fills less than the whole internal cross-sectional volume of the inflated tyre but should the tyre become deflated, the insert expands to fill or substantially so the internal volume of the tyre due to the increase in temperature caused by the increased flexing of the tyre and insert. The consequent return to or towards the normal operative tyre shape results in the tyre subsequently running at or near normal running temperature. The insert 10 may alternatively be formed by three side-by-side rings of the resilient material as shown in dashed lines in the drawing. <IMAGE>

Patent GB-2432984-A (GB)
Title: Distinguishing signals from noise
Inventor: GODDARD GRAHAM CLIVE
IPC: G01S7/292
Filed: 1979-05-31
Abstract: A signal receiver, for use on a Doppler radar system for example, discriminates between coherent received signals and background or jamming noise on the basis only of the phase of the input signal, rather than its amplitude. The output of a given Doppler filter 11 is supplied via a hard limiter 12, which detects the zero crossings, to a monostable 13. A low-pass filter 14 detects the mark-space ratio in the monostable output, which ratio will vary randomly when only noise is being received but will become steady when a coherent signal (i.e. of regular frequency) is present. Band pass filter 15 blocks such steady outputs, so producing a signal E which remains steadily at zero when a coherent signal is present. This condition is sensed by a threshold detector 16 which provides a logic 1 level when signal E is substantially zero and whose integrated (17) output will thus rise to exceed the threshold of detector 18 only when signal E remains at zero for some time. Large reflected signals interfering from adjacent Doppler frequency bands are blocked by network 21-23, and a signal representing Doppler frequency is derived at 24.
