Title: Improvements in or relating to polypropylene foam and process of making same
IPC: C08J9/00
Filed: 1963-09-19
Abstract: Polypropylene foam may be prepared by a process which comprises blending stereoregular polypropylene with a blowing agent and an azido cross-linking agent, and heating the blend at a temperature sufficient to release gas from the blowing agent whereby blowing and cross-linking of the polypropylene are effected. Chemical and solvent blowing agents may be used and exemplified are azobisformamide, trichlorotrifluoroethane, dichloromethane and pentane.  The preferred azido cross-linking agents are those having the general formula R(SO2N3)x where R is an alkylene, arylene, aralkylene or alkarylene radical and x is an integer greater than 1.  Many examples of azido cross-linking agents are given but 1,10-decane-bis(sulfonazide) and a chloroaliphatic hydrocarbon compound containing a plurality of sulfonazide groups are the ones preferred.  Other classes of azido cross-linking agents may be those having the general formulaae <FORM:1022051/C3/1> An elastomer, e.g. an ethylene-propylene copolymer, ethylene-propylene-diene terpolymer or polyisobutylene may also be included in the blend.  The foams from this process have a uniform cell structure in which at least 50% of the cells are closed and have densities of from 2 to 50 lb. per cubic foot.  They may be extruded into sheets, rods and tubes, coated on to wire and cables and compression moulded to form shaped articles.ALSO:A chlorinated aliphatic poly-(sulfonazide) is prepared by passing sulphur dioxide into a solution of a commercial mixture of hydrocarbons containing 11 and 12 carbon atoms per molecule in carbon tetrachloride, exposing the mixture to ultra-violet light and simultaneously passing in chlorine, removing the solvent under vacuum and adding dropwise to the resultant chlorosulfonated hydrocarbon in acetone a sodium azide solution in water.  After stirring and heating, the solvent is removed and the resulting mixture diluted with chloroform. The solution so obtained is washed with water and dried and on removing the diluent the desired product is obtained.  The chlorinated aliphatic poly-(sulfonazide) may be used as a cross-linking agent in the preparation of polypropylene foams (see Division C3).

Abstract: 934,248. Safety razors. PHILIP MORRIS Inc. Oct. 26, 1961 [Dec. 22, 1960], No. 38360/61. Class 30. A safety razor for singleedge blades comprises a blade seat 12 carried by a stem 8, a cover 22 swingably mounted on the stem for movement between open and closed positions and having a dependent rearward portion 29, a spring 28 urging the cover to the closed position, and a lever 36 pivotally mounted in the stem and formed with a cam surface 40 which engages the portion 29 to hold the cover closed when the surface is in a rearward position, which is movable to a forward position out of the path of movement of the portion 29, and which, when moved rearwardly, engages the portion 29 to move the cover to the closed position. The seat is secured to ears 10, 11 of the stem and has stops 16 against which the blade 18 is urged by a pressure finger 20 influenced by a spring 21 when the razor is in shaving position (Fig. 3). Ends 23 of the cover are pivoted on bearings 24 at the ends of the seat and one end of the cover-opening spring 28 is clamped between the ears 10, 11, the spring opening the cover when finger pressure is exerted on the lever 36 above its pivot point 38 in a recess 37 in the stem, to move the spring 21 in a recess 42 in the lever clear of the finger 20. Finger pressure on the lever below its pivot point closes the cover against the action of spring 28. A resilient arm 44 of the lever passes over a hump 45 in the recess 37 to provide slight resistance to movement of the lever to the cover-open position and to indicate to the user, by a clicking noise, the movement of the lever. A guard bar 50 is pivoted in arms 14 of the seat 12 and is swung on a horizontal axis to vary the distance between the cutting edge of the blade and the rounded top surface of the bar, and hence the shaving angle, by the engagement of a pivot post 56 on the operating bar 54 of the guard in a notch 58 in the end of an arm 59 on an operating link 60 which carries an arcuate lip engaging an eccentric formed as an annular groove 64 in an operating wheel 65 mounted in the stem 8 for operation by the user's thumb.

Abstract: 1444628 Analogue to digital converter HARTMAN & BRAUN AG 14 Aug 1973 [14 Aug 1972] 38427/73 Heading H3H In an analogue to digital converter, e.g. of the dual ramp type, calibration is obtained by integrating up a calibration voltage U Cal  for a first time interval and integrating down the converter reference voltage U o  for a second time interval, any difference between the time at which an output pulse from the comparator 16 occurs and the time the counter 21 attains a predetermined state, e.g. overflows, representing the calibration error which is converted to a direct voltage at 24 and superimposed on the converter reference voltage U o . As shown, a unidirectional counter 21 is continually fed with regular clock pulses from a generator 22. Starting from zero in the counter, U Cal  or U x , depending on whether a calibration or measurement is to be performed, is integrated up until the counter 21 overflows. Then U o  is integrated down until the comparator 16 gives an output K whereupon the state of the counter is transferred to an indicator 23. For calibration, the counter 21 should be in a predetermined state when K is produced; circuit 20 generates a pulse of width equal to the time difference between signal K and the counter attaining the predetermined state, which pulse is converted to D.C. at 24 and applied to correct the value of the reference voltage U o . Mention is made of the use of a bidirectional counter and of a half-scale zero bias.

Abstract: 1455957 Loading dock ramp OVERHEAD DOOR CORP 4 Sept 1974 [6 Sept 1973] 38671/74 Heading B8E The ramp deck 12 of a loading dock is urged to the raised dotted line position, Fig. 2, about a pivot 13 or a base 11 by a lift arm mechanism 14 comprising springs 16 urging an arm 23 clockwise to engage its roller 26 with a cam 27 to raise the deck. A hold down device 41 acts between the base 11 and the arm 23 to render the raising force of the springs 16 ineffective and comprises a slide bar 42 secured to a clevis 44, fixed on a plate 18 to which the springs 16 are secured, which slide bar extends through a block 51, Figs. 3, 4 where it is lockable against movement in one direction by a cam 53 engaging the bar 42 by serrations 54 to prevent sliding in that direction. The cam 53 can be released by pulling a grip connected to its arm 61 by a chain 62 and this releases the ramp 12 allowing the springs 16 to raise it with the lip 28 being raised by associated mechanism in the normal way. The grip 63 is then released but the ramp 12 can be trodden down into contact with a vehicle platform as the cam 53 is ineffective during downward movement but when the vehicle is contacted the springs 16 cannot again raise the ramp as the cam 53 bites into the slide 42 preventing it and the arm 23 from moving. Further lowering is not restricted but small upward movement of the ramp is possible due to the pivotal mounting of the slide 42 at each end and the pivot mounting of the springs 16 on an adjustment rod 19. The ramp 12 is supported by legs 39 in a storage position in which it is locked by means that must be released before use of the ramp in the usual way.
