Patent GB-1426595-A (GB)
Title: Liquid mixer dispenser
IPC: B01F5/00
Filed: 1973-04-18
Abstract: 1426595 Dispensing liquids R F ELECTRONIC CONTROLS (1970) LTD 18 April 1973 18805/73 Heading B1C Dispensing and mixing apparatus for liquid detergent in water comprises a housing with coaxial inlet and outlet passages 33, 44 respectively, separated axially by way of an air gap 20, within the bore of the outlet passage 44 there being provided a sleeve 36 within the passage 44 immediately adjacent the air gap and which form a constriction formed by an abrupt change in diameter downstream in the outlet passage. An auxiliary passage 42 is provided immediately beneath the constriction for the supply of detergent which can be controlled by a valve means 48, 50. In operation water entering the inlet passage passes across the air gap 20 into the bore 40 of the sleeve 36 and from the sleeve into the outlet passage, the action of the water due to the constriction entrains a flow of liquid detergent from the auxiliary passage and hence dispenses a mixture of water and detergent in proportion to the quantity of water flowing through the outlet passage. A slide rod 48 with an annular groove is provided in a bore 46 transverse to and intersecting the auxiliary passage 42 to permit or stop the flow of detergent. The apparatus has means 22 for sealing it to a tap and a filter and cover 30 are provided at the exit of the outlet passage. A needle screw 58 permits adjustment of the flow area in the auxiliary passage to control the flow of detergent. The function of the air gap in the apparatus is to permit air only to be sucked into the inlet passage 33 in the event of accidental covering or blockage of the outlet passage thereby preventing detergent from entering the main water supply.

Void [Abridged as open to inspection under Sect 91 of the Acts, Jan. 18, 1935]. [Class 40 (iii)] In a television system employing velocitymodulated scanning the output from the photo-cell amplifier at the transmitter is utilized as the television signal and is transmitted to the receiver where it is used to modulate the deflecting potentials applied to a scanning device for the purpose of reproducing at the receiver the movements of the scanning spot at the transmitter. The scanning spot on the screen of the tube 1 is focused on a picture 3 which is to be transmitted and behind which is placed a photo-electric cell and amplifier 4 the output of which is fed to the transmitter 10 and to the circuits 5, 7 where the deflecting potentials are modulated by the picture signals. At the receiver the deflecting potentials produced by the timing circuits 13, 14 are modulated by the picture signals and are applied to the pairs of plates 12, 15 to reproduce on the screen of the cathode-ray tube 17 the varying velocity of the beam at the transmitter. The timing circuits 13, 14 are maintained in synchronism with the corresponding circuits 5, 7 at the transmitter by impulses transmitted at the end of each line and picture. The receiving apparatus may be utilized in a system with intensity modulation of the cathode beam by moving a switch 19 to its upper position in which the picture signals are applied to the control grid 16 of the tube 17, the timing circuits 13, 14 controlled by the synchronizing impulses effecting the movement of the beam.

Abstract: 1,270,681. Paper-making apparatus. INDUSTRIAL NUCLEONICS CORP. 17 April, 1969 [3 May, 1968], No. 19748/69. Heading D2A. [Also in Division G3]  In a sheet (or web) processor, at least one parameter affecting a property of the sheet is controlled by a system in which values indicative of the property are determined at a plurality of points and the peak value of these (over a finite time) is compared with a predetermined limit value so that the property is controlled in a manner to cause it to approach said limit value. Unspecified scanners 25, 26 repeatedly traverse the width of a paper web leaving manufacturing apparatus and from associated circuits 28, 29 produce a voltage proportional to the moisture content and the inverse of basis weight (weight per unit area) respectively of the web. The peak value of these voltages during each or any number of scans is determined by circuits 31, 32 (and Fig. 2, not shown) in which the voltages in each case charges a capacitor which, after the requisite number of scans, is connected to an operational amplifier. The outputs are compared with the appropriate reference values 37, 38 and any differences above a predetermined magnitude adjust a steam supply 22 to drying rolls 21 and the water constituent 11 of the fibre and water pulp supplied to header box 17. The object is to ensure a maximum water content and a minimum basis weight in the finished product. The circuits 31 and 32 include a filter with a time constant such that short duration peaks are ignored. The capacitors are discharged at the beginning of each scanning period.
