Title: Body exhaust gown
Inventor: HOWORTH FREDERICK HUGH
IPC: A41D13/12
Filed: 1984-10-23
Abstract: A sleeved gown (10) is formed with an integral hoods (19) having a narrow front opening (21) in line with the eyes of a wearer (20). The material of the gown (10) is held in close contact with the wearer's face across the forehead and below the eyes but above the nose by means of tapes (22) tied around the hood (19). Exhaust duct means (11) extends over each of the wearer's shoulders beneath the gown (10) and has a plurality of exhaust inlets (14) in the region of the wearer's chest.Preferably, upward airflow is restricted to a vertical passageway formed by an outward billowing (25) of the gown material. This arrangement is most effective in drawing away air-borne emissions from the wearer's body, and causing ambient air to enter from the bottom of the gown (10) and gaps at each side of the wearer's nose. It is more comfortable than previous arrangements as there is no rigid mask or visor. Also as air extraction does not take place adjacent the wearer's face, no special communication equipment is required.

Title: Improvements in dynamometers
Inventor: BURCHETT CLIVE JOHN
IPC: G01M17/02
Filed: 1986-04-28
Abstract: In a dynamometer for testing tyres and/or wheels and brakes of aircraft, a tyre 12 in rolling contact with a drum 10 is mounted on a load transducer module 22 connected via mounting plate 24 to thrust plate 30 of a loading head. The camber angle required for the test is set by rotating a lead screw (34, Fig. 3) which has a travelling nut (36, Fig. 3) attached to plate 24 causing plate 24 to move relative to bracket 26. Angled tracks 40, 41 move through linear bearings formed in rotatably mounted bushes 60 so that as the plate 24 translates, its attitude relative to line of action 16 varies. The problem of preventing the centre of load 14 between tyre 12 and drum 10 from moving from its datum position is solved by supporting bushes 60 in arms 56 pivoted to bracket 26 on shafts 54. Control levers (64, Fig. 3) are connected to an adjustment screw 68 that rotates in one direction to converge the arms 56 and in the opposite direction to cause them to diverge. <IMAGE>

Title: Control system for regenerating a diesel engine exhaust filter
Inventor: JONES WILLIAM M
IPC: F01N13/04
Filed: 1986-11-07
Abstract: A system for controlling regenerative burning in a diesel engine exhaust particulate filter (20) comprises a first temperature sensor (30), a burner (32 to 38) and a second temperature sensor (42) mounted in that order upstream of the filter (20) in the exhaust system.The temperature sensors feed signals to a control device (50), which also receives signals representing pressure drop across the filter, engine speed and vehicle brake pressure. Device (50) initiates supply of fuel and air to the burner and actuates igniter (40) in response to predetermined conditions, for example when the engine is idling and the vehicle stationary with brakes on. A third temperature sensor inside filter (20) signals device (50) to stop the burner when all particulates have been burned. Device (50) may abort the regeneration if the engine speed rises. <IMAGE>

Title: Control apparatus for electric bed heating arrangements
Inventor: CHUTER BARRY IAN
IPC: H05B1/02
Filed: 1987-12-07
Abstract: A control apparatus for an electric bed heating arrangement (24) includes a 24 hour timer circuit (36) which, after the apparatus has been energised from an electrical supply: (i) disables energisation of the bed heating arrangement (24) until a manual operation of setting the timer circuit (operation of a reset/override switch) has been performed; and (ii) responds to the manual setting operation to commence a 24 hour cycle according to which energisation of the bed heating arrangement is enabled each day, at a time determined by the time of day at which the manual setting operation was performed, and continues thereafter to be enabled for a predetermined part only (e.g. 12 hours) of the 24 hour cycle. When, for example after first purchase or at the end of the warm season, use of the bed heating arrangement is to be commenced, the user need only connect the control apparatus to an electrical supply and then perform the manual setting operation at an appropriate time of day. Thereafter, provided the apparatus is left connected to the supply, heating of the bed will be enabled each day at the same time as that determined by the time at which the setting operation was performed and will be disabled each day at the same time, namely at the end of the predetermined part of the 24 hour cycle.

Patent GB-2209968-A (GB)
Title: Powder dispensing comb
Inventor: ALLUM WILLIAM HENRY
IPC: A01K13/00
Filed: 1988-09-12
Abstract: A powder dispensing comb comprises a plurality of teeth (1) some teeth (2) of which are hollow. The teeth are mounted on a plate (3) which closes the open side of a manifold (4) which is hollow. The hollow teeth (2) communicate through the plate (3) with the inside of the manifold (4) and the plate (3) may be secured by suitable fastening means or be a push fit or snap action or a welded or glued fit may be provided. An end of the manifold (5) includes a screw cap (6) which connects with a complementary screw threading on a flexible plastics powder container (7). Positioned within the cavity of the manifold (4) is a piece of foam material (8) which extends the length of the cavity and which has one side thereof in close proximity to the surface of the plate (3). In use, the container (7) is filled with powder material which, by a squeezing action, passes into the manifold and thoroughly impregnates the foamed material (8). Squeezing action causes the powder to be displaced through the foam and hence into and subsequently out of the hollow teeth (2). When the container is released suck back of air therein is permitted by virtue of the foam material powder is not removed from the manifold (4) in any substantial quantity and consequently the next squeeze on the container will result in immediate dispensing of further powder.
Patent GB-2222787-A (GB)
Title: Roller grader
Inventor: RODGER-BROWN DONALD
IPC: B07B1/10
Filed: 1988-09-20
Abstract: A drop roller grader has a number of spaced apart rollers (6, 14) supported by an endless chain. The rollers are rotated due to driving collars (9, 15) on their axes bearing against friction strips (10, 16) extending along the grader at each side of the grading pass. Alternate rollers drop down vertically along the grading pass by different amounts of each range of grading to provide even sorting of the articles which may be potatoes or other food crop products. The rollers comprise an upper series (6) which, in the grading pass, run at a fixed vertical level and a lower series (14). Each latter roller can drop vertically under gravity, as permitted by a slot (13) to a lower position in which the spacing between itself and each adjacent roller in the upper series is equal. The grading pass is divided into ranges such that the lower position from one range to the next provides a larger grading aperture. This is achieved by providing a vertically adjustable and settable frame member (17) for each range to support the friction strip (16) at such a level relative to the fixed friction strip (10) for the upper series that the rollers of the lower series continue to be rotated and supported. <IMAGE>

IPC: E03F1/00
Filed: 1989-01-25
Abstract: In a valve control system for opening a main valve (12 Fig. 1) when liquid in a temporary liquid storage tank (3) reaches a predetermined level, upon a rise in liquid level causing a predetermined and substantially constant air pressure to be applied to a port 25 a diaphragm 31 in a first chamber 29 moves to allow air to pass into a chamber 33 and move a second diaphragm 34 to cause activation of the valve control system, but a surge in pressure causes diaphragm 31 to block a passageway 32 into the chamber 33 and prevent activation of the system. In the preferred embodiment diaphragm 34 opens a duckbill valve (20 Figs. 6,7) which in turn causes opening of the main valve (12). <IMAGE>
