Patent GB-2142145-A (GB)
Title: Liquid level sensing apparatus
Inventor: EMBREY DEREK MORRIS
IPC: G01F23/26
Filed: 1983-04-27
Abstract: A liquid level is sensed by measuring the capacitance between coaxial plates mounted in a liquid container. The outer electrode is earthed and the common axis of the plates has a vertical component when the sensor is mounted for operation. In one arrangement the inner electrode is divided into two mutually insulated portions, so that while the liquid completely immerses the lower electrode, its capacitance with the outer electrode can be used as a measure of the dielectric of the liquid. The capacitance (CT) of the upper electrode with the outer electrode is varied in accordance with the proportion of the upper and outer electrodes which are immersed in the liquid and may be measured by a timing circuit in which each trigger pulse applied to (31) changes the state of bistable circuit 32 to one state and causes transistor TR1 to conduct to discharge capacitance (CT). The latter then charges through R1 until the voltage thereacross reaches the threshold potential of the gate of the circuit (32) to which it is connected. Bistable circuit then changes to its second state and the mark/space ratio of the square wave thus produced at output terminal (34) is indicative of the capacitance (CT) and hence liquid depth. <IMAGE>

Title: Apparatus and a process for removing residual liquid from a processing barrel
Inventor: HENIG HANS
IPC: C25D21/00
Filed: 1985-05-24
Abstract: In an electro-plating or similar processing installation, where bulk items 3 are processed in a perforate treatment barrel 2, liquid is removed from the barrel 2 and the contained bulk items 3 by placing the barrel 2 in a prismatic chamber 1 the dimensions of which conform closely to the shape of the barrel, the chamber having an air blowing duct 12 and an air suction duct 11 both opening into a lower part of the chamber 1. Air is then circulated through the chamber, by drawing air out of the chamber through the air suction duct 11 and blowing air into the chamber through the air blowing duct 12. The air stream 4 will thus flow through the barrel 2 in the chamber 1 and over the surfaces of items contained in the barrel. Liquid may be recovered at the original concentration from the air stream 4 for re-use in a treatment bath. Rinsing may simultaneously be performed by spraying water into the chamber, or the process may be operated to perform drying of the bulk items. <IMAGE>

Title: Weighing a number of objects in succession
Inventor: DOERMAN ERYK STEFAN
IPC: G01G9/00
Filed: 1986-09-10
Abstract: The objects 9 are projected with a known horizontal velocity onto a ramp 2 which has a surface which curves down through 90 DEG . The ramp 2 can move horizontally in response to the impulse corresponding to the change in horizontal momentum of the object 9. A transducer 5 senses the movement of the ramp 2 and a device 23, 24 senses the output horizontal velocity of the object 9, enabling the change in horizontal velocity to be calculated. The mass of the object 9 is calculated from the horizontal movement of the ramp 2 and the change in horizontal velocity of the object 9, on the basis of the conservation of momentum principle, by giving a signal which varies with the displacement of the ramp 2 and integrating said signal with respect to time to compute a weight signal for the object 9. <IMAGE>

Title: Emulsifying equipment and method
Inventor: KNOX JOHN HENDERSON
IPC: B01F5/00
Filed: 1987-05-14
Abstract: Emulsifying equipment comprises two cylindrical members (21, 29) between which an annular gap (11b) is formed. Liquids to be mixed are fed (via 12a, 12b) into the gap while relative rotation is maintained between the two cylindrical surfaces defining the gap (i.e. inner member 29 is rotated via shaft 30). The liquids in the gap are subjected to a substantially uniform shear in the range 3000 to 40,000 mm/sec. During mixing the liquids can flow through two gaps (11b, 11a) in passing from the inlet (12a, 12b) to the outlet (13). Each liquid is separately pumped into the gap since the rotating cylindrical surface(s) has no significant pumping action. <IMAGE>

Title: Performing raster operations on patch formatted pixel data
Inventor: TREVETT NEIL FRANCIS
IPC: G06T1/20
Filed: 1988-03-23
Abstract: A system and method for performing raster operations in a patch access environment utilizes two or more source patches to produce an XY shifted destination patch. The XY shifted patch is then operated on by a write mask so that selected portions of the XY shifted patch are written into the destination. Specifically, the written portions of the XY shifted patch are present in the destination only where permitted by the write mask. Even though the present invention operates in a patch access environment, it can form a destination patch by merging groups of pixels not residing within the same patch boundaries. The shifting and merging used to form the XY shifted destination patch can be done on a patch plane basis or on a patch basis. The X shifting and merging effectively combines preselected contiguous columns of contigous patches. The X shifted patches are then shifted in the Y direction. A line of the XY shifted patches is stored in a memory. A second contiguous line of the XY shifted patches is also stored in the memory. The stored lines are merged and patches can be read out of the memory in a page mode fashion. Boolean or arithmetic operations can be performed between the XY shifted patch and pre-existing data within a destination patch area so as to produce the XY shifted destination patch. <IMAGE>
