Filed: 1981-09-28
Abstract: In a demodulation circuit for producing a line-sequential signal from a frequency modulated S.E.C.A.M. colour information signal, change-over switch (17) operating at half line frequency rate alternately applies the output signal of a S.E.C.A.M. demodulator (3) to a first (33, 41, 45) and a second (35, 43, 47) clamping circuit the output signals of which are added together in an adder circuit (27), to cancel the disturbing component of half the line frequency produced in the output signal of the demodulator by the carrier frequencies which differ from line to line, on which the colour difference signals have been frequency modulated. <IMAGE>

Patent GB-2137449-A (GB)
Title: Target detection systems
Inventor: GARNER ALAN
IPC: G01S13/931
Filed: 1983-05-11
Abstract: A proximity detector is attached to the rear of a vehicle to provide an indication when the vehicle is about to reverse into an obstruction or over the edge of a precipice. An RF signal from an oscillator 6 is transmitted via an antenna 9 and received after reflection from a target by the same antenna element. The received signal is mixed at 10 with a sample of the transmitted signal to provide a beat frequency, the frequency of which is proportional to the delay between transmission of the signal from the oscillator 6 and reception at the mixer 10. The value of the beat frequency expected from targets within a region under surveillance is raised by using a delay line 8 which of course increases the delay between transmission and reception. The beat frequency is in this way raised above unwanted lower frequencies which arise from imperfections of the oscillator 6 which cause its amplitude to vary with frequency. Thus the output of a bandpass filter 12, designed to pass beat frequencies arising from targets within the region of interest, is unpolluted by the unwanted frequency and can be used e.g. by comparison with a threshold 14 to give with a great degree of reliability an indication of whether a target is present. <IMAGE>

Patent GB-2145178-A (GB)
Title: A load-responsive brake pressure regulator for vehicles
Inventor: RATH HEINRICH BERNHARD
IPC: B60T8/18
Filed: 1984-08-16
Abstract: An inlet chamber (28) adapted to be connected to a brake master cylinder and an outlet chamber (64) adapted to be connected to at least one wheel brake cylinder are each defined by respective displacement pistons (30 and 66) having effective areas which are at least nearly of the same size and being connected by a transmission unit 76 (72-80), the transmission ratio of which is variable in response to the load on the vehicle. The outlet chamber (64) communicates with the inlet chamber (28) through a valve (32, 34) as long as the pressure supplied by the brake master cylinder does not exceed a predetermined value. This value (32, 34) is controlled independently of both displacement pistons (30, 66) by a valve plunger (36) which is responsive to the pressure prevailing in the inlet chamber (28)-transmitted to space (48) by means of a passage (50 Figure 2 not shown)-and is at least substantially unaffected by the pressure prevailing in the outlet chamber (64). In this manner it is possible to adjust the pressure ratio between the inlet and outlet chambers (28, 64) in correspondence with the mechanical transmission ratio of the transmission unit (72, 80) selectively to a value below or above 1:1. <IMAGE>

The fin, clamped between the opposing flanges 24,25 stabilizes the gasket within the grooves and forms an aperture 32 between the pipe ends that establishes fluid communication between the pipe and the interior of the tubular gasket. The fin may be provided recesses to receive supplementary fluid seals (See Fig. 1). <IMAGE>

Title: Correction device for weighing machines
Inventor: HIRANO TAKASHI
IPC: G01G23/16
Filed: 1985-02-15
Abstract: A zero point correction device, particularly for an automatic repeat weighing machine 10 for powdered product, relies on the zero point deviating systematically from its initial position in known manner with increase of the number of weighed batches due to accumulation of the product remaining in the weighing hopper or cradle, whereby machine operation need not be interrupted. The curve of effective tape bn versus machine cycle number may be approximated by a series of straight line segments of gradient an, the latter being correlated in a memory 12 against points bn, where the gradient alters. The output of counter 14 determines which pair an, bn are read out, and counter 22 is arranged to count cycles from the last gradient change (for example x cycles) whereby the effective tape bx = anx + bn may be subtracted 24 from the machine output. In alternative embodiments, use is also made of the machine output between successive weighings. <IMAGE>

Title: Disposable waste containment garment
Inventor: BUELL KENNETH BARCLAY
IPC: A61F13/49
Filed: 1986-02-19
Abstract: A disposable waste containment garment (20) which is particularly useful and leakage resistant for bedridden incontinent adults has side-edge-leakage-guard gutters (45,46) having closed ends, and longitudinally elasticized distal edges (48). The gutters and the other garment elements are arranged to obviate inversion or unfolding of the gutters during application and use. The garment is sized so that, when secured on a user, the elasticized distal edges of the gutters will normally extend along the groin regions of the user, and diverge upwardly across abdominal, hip and lower back areas rather than encircling the thighs of the user. The absorbent core (42) of the garment is preferably sufficiently resilient to cause it to stand away from some lower abdominal and hip regions of the user. This, in conjunction with the gutters being sufficiently flexible and elasticized, causes adjacent portions of the gutters to be biased open, to act as reservoirs when fluid is received in the garment faster than it can be absorbed in the absorbent core of the garment, or whenever free liquid is squeezed out of a portion of the garment as when the weight of a bedridden user is shifted. The ends of the gutters in the waistband regions of the garment may be sealed liquid tight, or be secured closed with edge portions of the absorbent core and/or topsheet disposed therein, or a combination of such sealing and securing. <IMAGE>
