Patent GB-2223746-A (GB)
Title: Dispensing carton blanks
Inventor: HEMUS DAVID STANLEY
IPC: B65H1/24
Filed: 1989-10-06
Abstract: An inclined magazine 10 for flattened tubular blanks to be erected, product-filled and closed in a cartoning machine has a grating device 40 to hold the blanks securely in the magazine and release them one at a time at the bottom end of the magazine for collection by vacuum pick-off heads 22, 142 and 144 remounted on a common shaft 46 so that during a first part of each revolution, a large radius portion of the first disc 142 holds the bottom blank in the magazine while the second disc 144 is ineffective to separate the endmost blank from the adjacent blank, whilst in a second part of each revolution a large radius portion of the second disc 144 is interposed between the endmost blank and the adjacent blank so as to retain the adjacent and any further blanks in the magazine, whilst the first disc 142 is ineffective to hold the endmost blank in the magazine so as to permit its removal. As described, comprising two non-circular discs static retention catches (42 Fig. 1 not shown) hold the bottom blank temporarily after release by the gating device, and an escapement device 44 having two detents 50, 52 operate alternately to limit the downward force imposed by the blanks on the gating device. <IMAGE>

Title: Forming tools and methods of making such tools
Inventor: GR NBAEK JENS
IPC: B23P15/24
Filed: 1989-10-12
Abstract: A forming tool 1 comprises a die 2 with a forming cavity 3, an inner ring 4 lying against the die under radial bias, and an outer ring 5 lying against the inner ring 4 under radial bias. The material of the inner ring 4 has a higher modulus of elasticity than the material of the die 2 and the material of the outer ring 5. In particular, the inner ring 4 is of hard or cutting metal whereas the die 2 and outer ring 4 are of steel. That arrangement reduces the danger of fracture of the die.

Title: Method of quantitative analysis of drilling fluid products
Inventor: JONES TIMOTHY
IPC: G01N21/35
Filed: 1989-10-28
Abstract: A method of quantitative analysis of products, such as barite, bentonite or polymers, in a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of sampling the drilling fluid, and analysing the sample to determine the density of the fluid and the weight fraction of solids in the fluid. In addition, a known weight of the sample is dried to constant weight so as to obtain the products in the form of solids, which solids are analysed by an infrared spectroscopy technique. The concentration of the products in the drilling fluid is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment. <IMAGE>

Title: Specific surface areas of powders
Inventor: BUSHNELL MARK LESLIE
IPC: G01N15/08
Filed: 1990-06-11
Abstract: A method of measuring specific surfaces areas of powders uses a Wheatstone Bridge analogue circuit to avoid inaccuracies produced by the presence of the normal gaskets 32 in a sample measurement cell 15. A sample measurement cell (15) containing powder and gaskets (32) is positioned in a first arm (13) of the bridge; a reference cell (23) containing only gaskets (32) in series with a variable flow resistance (22) is positioned in a second arm 14 of the bridge, and flow resistances (17) and (25) are positioned in the third (16) and fourth (24) arms of the bridge. Pressure differences are read by manometers (19, 27, 30 and 31) and flow rates by flowmeters (18, 26) when gas is passed through the bridge from regulated source 10. In use, gaskets 32 are installed in the otherwise empty sample and reference cells 15, 23 and gas is passed through the bridge and the load resistances 17 and 25 are adjusted until the pressure drops across the first and second arms 13, 14 of the bridge as measured by the mercury, water manometer combination 30, 31 or a pressure transducer, are equal. The resistances 17, 25 are then locked, powder sample is introduced to sample cell 15, gas is passed through the bridge 13, 14, 16, 24, and calibrated variable resistance 22 is adjusted until the pressure drops in arms 13 and 14 are equal, whereupon the flow rates and pressure drops across sample cell 15 and reference cell 23 and variable resistance 22 are measured by flow meters 18, 26 and manometers 19, 17. <IMAGE>

Title: Variometer audio system
Inventor: PERRY RICHARD PATRICK
IPC: G01P1/08
Filed: 1991-03-18
Abstract: The output of a variometer, indicating the rate of climb or descent of an aircraft, is fed to a Controller (1) and a Waveform Memory (2) which contains a digitally recorded waveform which is replayed using digital to analogue converters (DACs) at a rate directly controlled by the variometer output signal, to allow control of the pitch of the sound produced. The volume of the sound is made proportional to the variometer signal by means of the DACs' voltage references. The portion of the Waveform Memory (2) replayed is determined by the amplitude and polarity of the variometer signal. The contents of the Waveform Memory (2) may be changed at time of production to dictate the nature of the final sound output. <IMAGE>
