Patent GB-830531-A (GB)
Abstract: 830,531. Gravity-separation apparatus ; purifying water ; treating waste waters. PISTA S.A. July 8, 1957, No. 21619/57. Classes 46 and 111. Water, especially used water, containing sand or sand and grease flowing along part A of a channel 4, Fig. 2, enters a receptacle 1 by a downwardly-inclined opening 6, Fig. 1, passing under a partition 6a, Fig. 2, which extends both above and below the normal water level 13 in the receptacle. The contents of the receptacle are moved in an anti-clockwise direction by optionally adjustable blades 12, such movement being assisted by the tangential flow of the entering liquid. The blades are mounted on a hollow shaft 9 rotated by a motor 10 and carrying at its lower end hollow perforated arms 11 to which compressed air is supplied down the shaft for aerating the water. Sandfree water passes beneath a partition 7a spanning the water level and over a weir 7b which determines the liquid level 13 into a part B of the channel 4 separated from the part A by a partition 5 over which water may pass during excessive flow. Sand settling in a collector 3 is withdrawn along a pipe 17 by an air-lift 18 and discharged into a trough 19. Grease rising to the surface of the water in the receptacle 1 is deflected by a hinged blade 16, Fig. 2, through an opening 15 into a chamber 14 the bottom of which is inclined towards the opening.

Title: Thermal mass flow sensor for fluids
Inventor: SATCHELL DAVID WILLIAM
IPC: G01F1/68
Filed: 1983-04-15
Abstract: A mass flow sensor operates by measuring the cooling effect of a flowing fluid on a body 2. The body is made from etched silicon with integral p-n diode junctions, transistors or resistors as thermal sensors 8, 9 and a diffused resistor 10 as a heater. A feedback control circuit increases or decreases the heater current to maintain a predetermined temperature differential between the sensors 8 and 9 in a balanced bridge network. The thin silicon body gives fast response and the feedback control circuit gives high accuracy suitable for monitoring the fuel/air mixture in a carburettor. <IMAGE>

Title: Improvements in or relating to sample slides
Inventor: HABICHT JONATHAN
IPC: G01N1/28
Filed: 1983-07-29
Abstract: A sample slide (10) is prepared for use for, e.g., immunofluorescence assay, by a method comprising forming permanent markings (12, 14) on a slide so as to divide the sample- bearing surface thereof into an array of discreet areas; cleaning at least the sample-bearing surface of the slide; applying masking medium such as varnish to the sample-bearing surface of the slide to cover the marked, discreet areas; treating at least the sample-bearing surface of the slide with a hydrophobic reagent; cleaning and polishing the sample-bearing surface of the slide; and removing the masking medium. The resulting slide has a hydrophobic covering on the sample-bearing surface thereof defining an array of discreet uncovered areas (where the masking medium was) separated by the hydrophobic covering. In use, small quantities of samples may be applied to the uncovered areas. In practice it is found that the covered areas of the slide are genuinely hydrophobic, thus eliminating or at least substantially reducing the risk of samples drying out, which has hitherto been a problem. <IMAGE>

Title: Wide bandwidth bandgap voltage reference circuit
Inventor: SMITH GREGORY J
IPC: G05F3/30
Filed: 1985-07-25
Abstract: A bandgap voltage reference circuit includes an amplifier circuit (40,41,23,25,50,51) that detects imbalances in a bandgap cell (2) and transmits the imbalance signal through only high bandwidth NPN transistors to achieve very high, stable gain and very high bandwidth. The output voltage (VREF) produced thereby is sampled to provide feedback to an input (100) of the bandgap cell. Avoidance of active PNP transistors in the signal path results in a simple, yet very high bandwidth, bandgap voltage reference circuit and stable, highly predictable, highly reproducible circuit performance. <IMAGE>

Title: The production of pipes
Inventor: ADLAM JOHN MAURICE
IPC: B29D23/00
Filed: 1985-10-18
Abstract: Fibre-reinforced resin pipes are produced by laying-up and winding on a mandrel 15. A pin or male thread forming head 22 comprising a mounting member 23 is slidable longitudinally of the mandrel 15 and carries a plate 28 on which four blocks 34 are slidably mounted. The blocks are biassed radially outwards by springs 43 and have hydraulic rams 45 to drive them radially inwards. The blocks 34 carry permanent magnets 35 by which four pin thread former segments 36 are retained. The segments are pressed against the uncured pipe and are then temporarily retained in position by pressing retainer bars (55, Fig. 8 not shown) through grooves formed by rebates (53) in the ends of the segments, the bars being restrained at one end by the mounting member 23 and at the other end by a clamping ring (61). The blocks 34 are then radially retracted, the forming head 22 is moved longitudinally away and another clamping ring (62) secured around the segments 36. The retainer bars and ring (61) are then removed. The tube on the mandrel together with the segments still held in position by the ring (62) is removed to a curing station. <IMAGE>

Patent GB-2181912-A (GB)
Title: A clamping circuit
Inventor: MILLWARD JOHN DAVID
IPC: H04N5/18
Filed: 1986-05-15
Abstract: The clamping circuit clamps a threshold of an analog to digital converter to a signal level just below the black level of a television signal. During the blanking period, a negative-going peak is superimposed on the input signal to produce the waveform 76. Each time this crosses the 0000,0001 threshold of the ADC, the polarity of the output 77 of a comparator changes. The comparator compares the ADC output and a reference value. The input signal is biased according to the integral of the comparator output. When signal levels are stable, the comparator output is symmetrical, its integral is zero and no change occurs in the biassing. If signal levels drift, the negative going peak crosses the threshold for the second time relatively sooner or later. The comparator output becomes assymmetric and has a non-zero integral. Consequently, the biassing level changes to compensate for the drift. <IMAGE>
