Title: A method of and apparatus for separating liquid from solids entrained therein
IPC: B03D1/14
Filed: 1981-03-25
Abstract: The invention relates to a method of and apparatus for separating liquid from solids entrained therein, which solids, preferably paint particles examating from a paint spray booth are capable of floating on the liquid. The liquid and solids are entrained in a collector 1 which is open to  atmosphere and in which a Coanda- type flow prevails so that the solids are collected as skin 11 on the surface of the liquid. In one embodiment the level of the liquid is raised from L to L<1> so that the skin 11 slips over a lip 8 and out of the collector, leaving the liquid behind; in another embodiment the skin is collected behind a restraining device (12) which is moved to allow the skin to flow through an outlet therefor, again leaving the liquid behind. <IMAGE>

Patent GB-2092778-A (GB)
Title: Ventilation Controllers
IPC: G05D23/24
Filed: 1981-11-30
Abstract: An electronic control apparatus Fig 1 is arranged to cause a ventilator to open or close dependent upon the deviation of the sensed temperature from a pre-selected required value, set at 17. In response to a sensor 10 detecting a temperature deviation greater than a particular amount, the motor of the ventilator is energised in the appropriate sense for a limited period. This period is either manually pre-set at 19 or determined by the apparatus dependent upon the magnitude of the deviation from the required value (Figure 3). If the sensed temperature is greater than the required value by a greater amount, then a circulation boost fan is energised, whereas if it is smaller than the required value by a greater amount, then a heater is energised. Once energisation of the ventilator motor has occurred further energisation thereof is inhibited for a fixed period, selected at 20, to give time for equilibrium to be established. The application to livestock roaring pens is contemplated. <IMAGE>

Title: Improvements relating to conveyors
Inventor: BUSH ANTHONY
IPC: B65G39/16
Filed: 1981-12-01
Abstract: Conveyor belts are guided over sets of rollers (transomes) which form the belt into a trough, and the attitude of the rollers can be arranged to generate a self-centering action on the belt. In order to have this for a reversible conveyor (24), the rollers (21, 22, 23) are mounted on a frame (25, 26, 27) which can freely pivot within limits set by stops (30) about an axis transverse to and below the conveyor. This automatically takes up position where the outer rollers (22, 23) have their axes directed upwardly, outwardly and downstream of the conveyor motion. <IMAGE>

Title: Positive-displacement fluid-machines
Inventor: COLGATE STIRLING A
IPC: F02B1/04
Filed: 1982-09-13
Abstract: In a machine that may be a rotary compressor or expander of the sliding- vane type, Figure 3, inlet and outlet chambers 61, 62 are configured such that the working-fluid flow therein is "near lamina". Alternatively, the machine may be a reciprocating air compressor, Figure 6, having an air inlet port 96 configured such that the flow of incoming air is near lamina. Vanes 101 may render said flow also vortical, Figure 9B (not shown). The port 96 is controlled by a sleeve valve 95. The machine may be a reciprocating I.C. engine, Figures 10-18, wherein the ingoing flow of working fluid is both vortical and near lamina. The near lamina flow reduces heat losses. <IMAGE>

Title: Fuel injection system
Inventor: PALMER DON CHARLES
IPC: F02M45/06
Filed: 1982-11-23
Abstract: A fuel injection system for a compression ignition engine includes a pump 10 for supplying fuel at high pressure to an injection nozzle 11. The outlet of the pump is connected to one end of a first cylinder 13 the other end of which extends into a second cylinder 14 of smaller diameter. The one end of the second cylinder remote from the first cylinder communicates with the nozzle 11. Respective pistons 16, 17 are located in the cylinders and the first cylinder has a spill port 19 which can be covered by the first piston following the opening of a bypass path defined by a groove 22 on the second piston. The delivery of fuel through the nozzle is initially at a slow rate as determined by the displacement of the second piston 17 followed by an interval during which the pistons move until the spill port is covered and in which fuel is supplied to the engine followed by delivery of fuel as determined by the pump. <IMAGE>

Title: Fuel burner for a gas turbine engine
Inventor: POLLARD RICHARD EDWARD
IPC: F23D11/00
Filed: 1983-07-23
Abstract: A reflex airspray burner of the type shown in UK patent no. 1427146 is modified to enable a gas turbine engine to be started and accelerated to idle using a heavier fuel such as diesel. The improvement consists of directing a coherent jet of high pressure primary liquid fuel from a fuel injector (44) to impinge upon an impingement surface (28b). The impingement causes atomisation and even distribution of the fuel which is then mixed with air flowing through a burner duct (26) and the mixture issues in a generally radial sense through an annular outlet (48). A main fuel flow can be provided either in the form of an atomised cone (60) or an annular coherent high pressure jet (62) (Fig. 5 not shown), which is also atomised by impingement on the surface (28b). <IMAGE>

Title: A casing for a projectile
Inventor: ASSMANN HANS
IPC: F42B30/08
Filed: 1983-08-03
Abstract: A stable, gas-tight connection is formed between a metal lower portion (1) of a grenade casing and a grenade cap (2) of plastics material, which is injection moulded onto the lower portion. The outer wall of the lower portion (1) must be retained as a cylindrical guide surface for firing, and the outer surface of the cap (2) of the projectile must be flush with the outer wall of the lower portion (1). In the connecting region, the lower portion (1) has inwardly directed, annular holding projections (8) and plastics material, which is injection moulded thereon, of the cap (2) engages behind the projections, so that the cap (2), upon cooling, by virtue of the higher coefficient of thermal expansion of the plastics material, sealingly presses into the undercut configurations of the projections (8). <IMAGE>

Title: Rotatable air deflectors for electric fans
Inventor: FA-CHIEN HUNG
IPC: F04D25/10
Filed: 1983-10-07
Abstract: The fan has rotatable air deflecting blades (2) arranged such that on rotation thereof the air stream is varied cyclically from a minimum non-zero value to a maximum value. The blades form a shell which encloses the fan and is rotatable about a vertical axis. The blades are divided into 3,4,5 or 6 groups in which the blades at the centre of each group are disposed substantially parallel to the radial direction and the blades at the edges of each group are inclined relative to the radial direction so as to deflect the draught from the fan. A handle in the base (5) enables the fan to be pivoted about an axis substantially perpendicular to the axis of rotation of the shell. <IMAGE>

Title: Movement detecting apparatus
Inventor: STRAW D A
IPC: B66B1/34
Filed: 1983-12-22
Abstract: A very sensitive indicator for a winding drum used at collieries consists of a toothed wheel rotating between a light emitter and a light detector. The pulses of light received by the detector are counted until a preprogrammed count is reached when the speed of the winding drum is reduced prior to stopping it with the lift at a certain level. Two detectors 10, 12 located side by side are used and positioned so that one of the detectors is always fully off or on whenever the other is in an intermediate state. The detector circuit looks for a change in state of both detectors to protect against vibrations causing a count, and determines the sense of movement by detecting which of the detectors changes state before the other. <IMAGE>
