Abstract: 1328345 Reciprocating pumps; centrifugal pumps DEARBORN CHEMICALS Ltd 29 Sept 1970 [30 Sept 1969] 47911/69 Headings F1A F1C [Also in Division F4] A system for supplying treatment chemicals to a boiler at a rate proportional to the supply of feed water comprises a treatment chemical supply pump 52,the delivery rate of which is controlled in accordance with the setting of a modulating valve 12 controlling the feed water supply. The setting of valve 12 is controlled by a float 44 sensing the boiler water level and acting through a switch 46 to control solenoid valves 32, 34 in lines 36, 38 connected to pressure and suction respectively. A fall in water level opens valve 34 to raise piston 22 by spring 26 to open valve 12, and a rise in level opens valve 32 to lower piston 22 and close valve 12, a feedback system 48 functioning to achieve a setting of valve 12 appropriate to the water consumption rate of the boiler. As shown, pump 52 is of centrifugal type driven by a D.

Title: Method and apparatus for automatic analysis of brain wave signals
IPC: A61B5/0476
Filed: 1972-08-29
Abstract: 1339213 Electro-medical apparatus HUMETRICS CORP 29 Aug 1972 [29 Sept 1971] 39998/72 Heading G1N An EEG signal is evaluated by applying it to a 3À5-7À0 Hz detector 28 which provides a pulse signal having a pulse width related to the frequency of the waveforms of the EEG signal, the pulse signal being applied to an integrator 30 which integrates the signal over a pre-set time interval, the integrated value being compared with a pre-set reference so as to provide an indication if the integrated value reaches the reference within the pre-set time interval. In the detector 28, the EEG signal, Fig.2 (A) is compared with a reference voltage to provide a spike, Fig.2 (B) each time the signal crosses the reference. The spikes reset a ramp voltage, Fig.2 (C), each ramp having the same slope S. The output of the ramp generator is compared with two reference voltages V 1  and V 2 , voltage spikes, Fig.2 (E), being produced when the ramp exceeds V 1  and spikes, Fig.2 (F), being produced when it exceeds V 2 . The pulse signal, Fig.2 (D), is then produced, spikes E initiating respective pulses and respective succeeding spikes B or F terminating respective pulses. The energy content of the pulses is then integrated to provide a signal, Fig.2 (G), which is compared with a reference V 3 . From Fig.2 it will be seen that for a low frequency waveform in the EEG signal which causes the ramp to exceed the reference V 2 , a maximum width pulse P 2  is produced, the arrangement being such that the polarity of the signal applied to the integrator is reversed thereby eliminating the effect of this maximum width pulse P 2 . As shown in Fig.2, two channels are provided, the right being identical to the already described left. A timing and control circuit 20 is provided and is responsive to the EEG signal and to a signal from a 60 Hz detector to control operation of the various components of the system and to inhibit operation when interfering 60 Hz components are detected.

Abstract: 1349546 Endless conveyers BANDO KAGAKU CO Ltd 7 Sept 1971 [7 Sept 1970 27 Feb 1971 24 May 1971 3 July 1971] 41740/71 Heading B8A [Also in Division G1] Longitudinal cracks in a conveyer belt are detected by embedding at intervals along and across the width of the belt rubber magnets 5 which are short circuited by iron plates 6. If a longitudinal crack appears in the belt near one of the magnets 5 this will be ruptured and the associated iron plate 6 displaced therefrom so that the magnetic flux from the magnet is no longer short circuited and reaches a detector positioned under the belt. The detectors may be inductance coils, magnets, diodes, relays or magneto resistors connected in a circuit, Fig. 5 (not shown), which controls the belt motor to stop the belt when a crack is detected. A plurality of detectors may be distributed over the whole width of the belt or a single extended detector used. In order to prevent the iron plates 6 being ruptured together with the rubber magnets, particularly when a wide belt is used, each single magnet 5 is replaced by a plurality of magnet elements having corresponding iron plates and are disposed in a zig-zag arrangement on the belt, Fig. 8 (not shown). Leakage magnetic flux effects are obviated by using a single detector and consecutively arranging a plurality of magnet/plate pairs transverse to the belt but at different longitudinal displacements so that they lie along a line inclined to the belt in a stepwise arrangement, Fig. 9 (not  shown). In order to ensure that the belt is not stopped by the detection of leakage fluxes the detector  Fig. 11 may include two main detectors 4bL; 4bR and two auxiliary detectors 4aL, 4aR which are connected in a circuit Figs. 12 or 13  (not shown) whereby in the absence of a crack both main detectors emit identical signals and when a crack is present one signal is greater than the other, and only when a signal is simultaneously generated by both auxiliary and main detectors will the control circuit be energized. Reference has been directed by the Comptroller to Specification 1,151,335.

Inventor: KROEGER BRIAN WILLIAM
IPC: H04H20/82
Filed: 1999-10-28
Abstract: This invention provides a method for reducing FM interference in an in-band on-channel digital audio broadcasting system. The method includes the steps of receiving a composite signal including a signal of interest and an interfering signal and normalizing the composite signal to produce a normalized composite signal. The composite signal is then multiplied by the complex conjugate of the normalized composite signal to produce a real signal. Then the real signal is filtered and the resulting filtered signal is multiplied by the normalized composite signal to produce an output signal. The adverse effects of the interfering signal in the output signal are reduced with respect to the magnitude of the signal of interest reducing FM interference in an in-band on-channel digital audio broadcasting system, thereby making it easier to detect the signal of interest. The output signal and the composite can be blended in response to the power of the real and filtered signals Radio receivers that utilize the above method are also included.

Title: Method and apparatus for digital communication in the presence of closely spaced adjacent channels
IPC: H04J1/12
Filed: 1996-05-22
Abstract: A single transducer digital communication receiver is described which is capable of extracting the data bits of at least one desired signal in the presence of interfering signals of similar type. The present invention also seeks to provide a communication system in which overlapping transmissions are tolerated and allowed. The present invention describes a design for a digital communication system, according to a specific frequency plan, which includes an appropriate digital demodulator that extracts the data bits of the desired signal(s) in the presence of closely spaced signals. The present invention enables reduced channel spacing in digital communication systems and thereby increases the system capacity (i.e. the number of users per bandwidth unit) without incurring any significant loss in system performance (e.g. power margins, BER, and channel availability). It also allows a reduced power margin that is required to maintain a pre-specified performance level without sacrificing system capacity. These two factors, power margin and system capacity, play a central role in the design and construction of state-of-the-art digital communication systems which seek to pack more users on the same frequency band without incurring significant power loss. Thus, the present invention also provides a method and apparatus for upgrading existing systems such as a cellular system for mobile wireless communications that is based on the IS-54 or the GSM standard.
