Title: Combustion air control in an in-line flame arrestor
Inventor: WILLIS WILLIAM ROBERT
IPC: F23N1/02
Filed: 1984-05-31
Abstract: Mounted on the entrance end of a firetube 1, the two screen elements (11) and (12) of an in-line flame arrestor are linearly spaced along a tubular core. A common aperture (10) through the core wall is formed between the two screens. Combustion air directed through either, or both, screen elements (11), (12) enters the core through the aperture (10) in the core wall to supply a fluid-fuel burner (2) mounted within the core both primary and secondary portions of the combustion air. The effective size of the aperture is adjusted by a movable, internal sleeve (14) within the core with linkage (17, 18, 19) to the fuel supply system (15), (16) of the burner (2). The quantity of air is thus regulated in response to the rate of fuel supply, as measured by the fuel pressure acting on the linkage. <IMAGE>

Title: Gas detection systems
Inventor: POWELL BRIAN DAVID
IPC: G01J1/16
Filed: 1985-08-08
Abstract: A gas sensor for detecting the concentration of a gas or vapour which has an absorption wavelength in the UV radiation band of approximately 130 to 250 nm comprises a UV source (2) at a fixed distance from a housing containing two UV detectors (6, 8) which each receive a part of the radiation transmitted from the source through the gas or vapour. One detector (8) has a sensitivity which includes the absorption wavelength of the gas to be detected. The other detector (6) has a sensitivity which is close but excludes the absorption wavelength. The ratio of radiation falling on the two detectors is measured by circuit 20 and from this the concentration of the gas is calculated. The detectors are gas discharge UV photocells which produce pulses at a frequency dependent on the amount of radiation received. <IMAGE>

Title: Electrochemical gas sensor
Inventor: LAUER JAY M
IPC: G01N27/49
Filed: 1985-11-19
Abstract: A gas sensor cell includes an insulator body 14 having a central passage 16 divided into a first cell chamber 18 and a second expansion chamber 20 by a flexible expansion membrane 22. The cell chamber contains an anodic mass 30 of a nonpolarizable metal and is enclosed by a uniformly curved cathodic member 74 of polarizable metal which is covered by a membrane 84 impervious to liquid but pervious to gas. An electrolyte fills the cell chamber. The cathode and the gas permeable membrane are covered by a fibrous layer 110 which is pervious to gas and is in turn covered by a metallic mesh 112 held in place by a ring disc 114 held securely to the insulator body. The metallic mesh and the fibrous layer hold the cathode membrane uniformly and tightly against the cathode of the cell so that the membrane does not lift or change its position under conditions of increased internal pressure and, consequently, incorrect results are eliminated. <IMAGE>

Patent GB-2186440-A (GB)
Title: Transit for cables and pipes
Inventor: TWIST MICHAEL
IPC: H02G3/22
Filed: 1986-02-11
Abstract: The invention concerns a lead-through transit for cables 3 or pipes of the kind having a frame 1 of the the opening 2 is filled by a series of modular resilient lead-through blocks 4 and blank blocks 5 arranged in rows separated by stayplates 6 with a compression and packer assembly 7 clamping and holding the blocks 4,5 and cables 3 in sealed engagement. The lead-through blocks 4 comprise two complementary half-­blocks 40 that provide, when assembled together around a cable, a passageway 41 for the cable. Each half-­block 40 has a series of axially spaced semi-annular lands 42 separated by recesses 43. The lands 42 provide axially spaced sealing faces for engagement with the cable whilst the recesses 43 enable resilient deformation of the block to accommodate variations in cable size. To assist in such resilient conformation of the half-blocks 40, it is preferred that the half-­block has recesses 44 formed on the outer faces that are aligned with the lands 42. Various arrangements of the lands 42 and recesses 43 or 44 in the resilient conformable lead-through blocks are described to provide the advantage of reducing the numbers of blocks required for service and installation requirements.

Title: Feeding discrete objects; suction pick-up with air-blast release
Inventor: TURNER WILLIAM JAMES
IPC: B65G47/14
Filed: 1986-03-18
Abstract: In order to feed small objects one by one, there is a rotary bowl 2 with a highly resilient foam plastic insert 12 providing a V-shaped annular trough to which the objects are fed. There is a rotary feeder head whose axis is inclined to the axis of the bowl 2. The feeder head 38 carries a nozzle wheel 4 with a number of suction nozzles 47, arranged so that the nozzles 47 pick up successive objects from the bowl 2. As the nozzle wheel 4 rotates, ports 52,53 on the nozzle wheel 4 register with stationary ports 58,59 to which compressed air is supplied. The ports 52,58 cause the suction to be released and the ports 53,59 cause a blast of compressed air to be blown through an annular array of discharge openings 49. The insert 12 enables the relatively delicate nozzles 47 to be used and the porting arrangement 52,53,58,59 causes precise release and ejection of the objects after pick-up. <IMAGE>

Title: Pallet
Inventor: COX DAVID MICHAEL
IPC: B65D19/44
Filed: 1986-05-22
Abstract: Barrels (31) are stacked using a pallet (30) which is fitted between adjacent layers of barrels (31). The pallet (30) has a plurality of barrel receiving parts, each with a step formed by three faces (35,36,37). One face (35) is generally horizontal and fits between adjacent rim flanges of barrels (31) in adjacent layers, whilst the other two faces (36,37) extend in opposite directions outwardly of the plane of the face of the one face (35). Thus a face (36) fits within the rim flange of the barrels of the lower layer and a face (37) fits around the rim flanges of the barrels of the upper layer, preventing sideways movement of barrels in the stack. Reinforced channels 32 may be provided at the sides of the pallet (30) to enable the pallet (30), and thence the barrels (31) on it, to be lifted using a forklift truck. The pallet may be formed with a double step and be able to receive barrels of different sizes. <IMAGE>

Title: Weighing apparatus
Inventor: TAYLOR MICHAEL PHILLIP
IPC: G01G3/147
Filed: 1986-09-26
Abstract: A fully electronic portable weighing apparatus 1 is housed within a case 2 comprising a body 3 and removable lid 4. A flat cover 5 of washable plastic material is fitted in the body 3 in a fluid tight manner. Above the cover 5 is sterilizable plastic weighing platform 7, detachably mounted on a support frame 50 (Fig. 3) and made up of a centre portion 8 and two hinged end portions 9 which can be folded flat upon the centre portion 8. The support frame 50 links the platform with a load cell 20 which emits an output signal which is used to calculate a weight shown on a visual display 13. The apparatus is particularly suitable as a portable apparatus for weighing babies. The load cell emits an analogue voltage signal in response to the article being weighed. This signal is amplified and then passed through a temperature compensating circuit to an A/D converter which produces a train of digital pulses whose repetition frequency is proportional to the analogue input signal. The number of pulses is counted over a predetermined time period in a logic circuit to provide an average weight value which is displayed at display 13. A calibration mode enables the weighing apparatus to be quickly recalibrated using a standard weight applied to platform 7. <IMAGE>
