Title: Vulcanising rubber and rubber-like substances
IPC: C08K5/00
Filed: 1931-06-30
Abstract: Acid diphenylguanidine oxalate and tartrate are prepared by adding diphenylguanidine to a boiling aqueous solution of the acid in equimolecular proportions.  The acid phthalate is prepared by refluxing equimolecular proportions of phthalic acid and diphenylguanidine.  Using di-o-tolylguanidine the corresponding salt is obtained.ALSO:The vulcanization of rubber and the like is accelerated, and the tendency to scorch reduced by the addition to the mix of a 2-mercaptoarylene thiazole in conjunction with the acid salt of a diarylguanidine with a polybasic carboxylic acid, preferably in equimolecular proportions.  The 2-mercaptoarylene thiazole confers good ageing properties on the vulcanized material. It is stated that the use of the two above classes of compounds produces the Two Accelerator Effect, with resulting high tensile strengths of the product.  Diarylguanidines mentioned are Diphenyland Di-o-tolyl-guanidine.  Acids mentioned are oxalic, malonic, tartaric, citric, and phthalic acids.  Directions are given for the preparation of acid diphenylguanidine oxalate, acid diphenylguanidine tartarate, and acid diphenylguanidine phthalate.  Examples are given showing the effects of the addition to the mix of the above mixed accelerator and of mixtures of 2-mercaptoarylene thiazoles diphenylguanidine and a free dicarboxylic acid.  In the latter case there was a distinct tendency to scorch which was absent in the former case.  Acid Diphenylguanidine oxalate and tartarate are prepared by adding diphenylguanidine to a boiling aqueous solution of the acid, in equimolecular proportions.  The acid phthalate is prepared by boiling under reflux for half an hour equimolecular proportions of phthalic acid and diphenylguanidine.  If di-o-tolyl guanidine is substituted for diphenylguanidine, the corresponding salt is obtained.

Title: A system for stabilizing the position of a movable body in relation to a fixed body
Inventor: FORTIER ANDRE
IPC: F16C32/06
Filed: 1970-04-22
Abstract: 1284339 Bearings A FORTIER 22 April 1970 [23 April 1969] 19173/70 Heading F2A [Also in Division G3] A system for stabilizing the position of a movable body in relation to a fixed body comprises at least two opposite pressure zones separating said two bodies, a slide valve for connecting pressurized fluid to said zones, and control means for said slide valve. In an embodiment a fluid bearing comprises a rotational member 5, having a cylindrical-shaped extension 23, and a non-rotatable member 1 having a bore 2 and two diametrically opposed chambers 3, 4 therein. Pressurized-fluid is supplied to the chamber 3, via a line 12, an adjustable restriction 13, a tube 14 and a source 11, and is supplied to the chamber 4, via a line 16, an adjustable restriction 17, a tube 18 and the source 11. Pressurized-fluid supplied from a source 35, through a jet 36, a line 33, a tube 44 and jet 22 impinges on the extension 23 of the member 5, and pressurized-fluid supplied from the source 35 passes through a jet 37, through a line 34 and through a restriction 45 to atmosphere. The restriction 45 is equal to the restriction 22. In use the jet 22 is located a predetermined distance from the extension 23 and any movement of the latter towards or away from the jet 22 causes an increase of pressure in the respective chamber 3 or 4 and a decrease of pressure in the other chamber 3 or 4. This is effected by means of a differential control device which comprises a disc 25 mounted by means of a membrane 48 between chambers 28, 29 which are formed in a member 21, valve members 55, 56 which engage the disc 25 and throttle openings 41, 42, respectively; valve members 58, 59 which engage the valve members 55, 56, respectively, and adjust the restrictions 13, 17, respectively, and by means of throttles 31, 32 which connect the lines 33, 34 to the chambers 28, 29, respectively, and are adjusted by needle valves 51, 52, respectively. If, for example, a force F was applied to the member 5, the distance between the extension 23 and the jet 22 increases, the pressure in the line 33 decreases, the pressure in the chamber 28 decreases, the disc 25 moves upwardly to raise the valve members 55, 56, 58 and 59 to decrease the pressure in the chamber 3 and to increase the pressure in the chamber 4 sufficiently to resist the force F. In view of the variations in pressure in the lines 33, 34 being effected by pressurized-fluid passing through the restrictions 31, 32, the movement of the disc 25, and consequently of the valve members 55, 56, 58 and 59, is damped.

IPC: G01J3/42
Filed: 1954-07-01
Abstract: 814,072. Infra-red testing arrangements. MERVYN SOUND & VISION CO. Ltd. Sept. 30, 1955 [July 1, 1954], No. 19305/54. Class 40 (3). An infra-red testing device for determining the ability of a test sample 15 to pass radiations of varying wavelengths includes means compensating for variations in source output and response device sensitivity. The source 10 is mounted inside a chopper drum 11 driven by motor 12 and having a castellated interrupting part (see Fig. 1A). Radiation passing out of the drum is directed by mirrors 13 and 14 through the sample 15 and a correcting filter 16 to a slit 17. The energy from slit 17 is collimated by mirror 18 and directed to diffraction grating 19. Energy of a selected requency reflected by the grating is directed by mirror 20 through slit 21 on to mirror 22 and thence to radiation responsive device 23. The device 23 is also responsive to energy from the source 10 passing through slits 25 in the drum 11 and reflected by mirror 26 through adjustable slit 27. The slots 25 are so positioned that " reference " illumination through them only reaches device 23 when the beam through sample 15 is obstructed. The electrical output of the device 23 is amplified at 24 and fed to two output devices 32, 33 through a commutator switch 28 driven synchronously with the drum 11 by motor 12. This switch directs output pulses corresponding to radiation passing through sample 15 to output device 32 and those corresponding to radiation passing through slots 25 to device 33. Device 33 incorporates an integrator and is used to control the gain of amplifier 24 to compensate for any variation in response due to any variation in the output of the source or the sensitivity of the device 23. Output device 32 also includes an integrator and feeds an indicating instrument 36 and recorder 37 through an isolating stage 35. The recorder may co-operate with a drive rotating grating 19 so that a record of response over a waveband can be made. In a modification (Fig. 2, not shown) alternate half-cycles of the output of amplifier 24 are applied across a load resistor and the output across the whole resistor taken during reference pulses and integrated. The output from an adjustable tapping point on the resistor is taken during the times that radiation is received through the sample and is also integrated. The output of the two integrators are compared and used to control the positioning of the tapping point to obtain equal outputs and also an indicator and/or recorder.
