Abstract: 1,192,752. Levels. VE SPEZIALBAUKOMBINAT MAGDEBURG. Sept. 5, 1967, No. 40617/67. Heading G1F. Apparatus for determining the height of the head 1 on a pipe 2 during insertion into a bachole in a well comprises a measuring vessel 5 at the head 1 to which is connected a measuring conduit 10 leading to a graduated measuring tube 13, an overflow conduit 11, through which liquid overflowing over an edge in the vessel 5 is returned to a collector vessel 14 by a suction device 15, and an air conduit 12 vented to atmosphere, the arrangement being such that with liquid filling the system up to the level provided by the edge in the vessel 5, the height of the head 1 can be determined from the height of liquid in the tube 13. In the embodiment shown in the drawing, the vessel 5 is partitioned into two measuring chambers each having an overflow edge and each connected by a conduit 10 to a measuring tube 13. Separate overflow and air conduits 11, 12 are also provided, and by this apparatus the angle of rotation of the pipe 2 about its axis from a datum can be determined from the difference in height h between the two columns of liquid in the two tubes 13. In use the system is filled from the vessel 14 to overflowing, the liquid flowing over the edges in the vessel 5 being returned to the collector vessel 14, and the heights in the tubes 13 noted. Provision is also made for removal of the vessel 5 from the pipe 2 by securing the vessel 5 to the end of a de-silting pipe 3 inserted into the pipe 2.

Title: Polymer compositions
Inventor: CLARK KEITH JASPER
IPC: C08F210/00
Filed: 1963-10-15
Abstract: A copolymer composition comprises isotactic polypropylene and contains polymer units of a second a -olefin, the homopolymer of which melts above 180 DEG  C., the composition containing at least 70% of propylene monomer units by weight of the polymer. Polymerization is effected sequentially in the presence of a stereospecific catalyst and a hydrocarbon diluent, e.g. heptane. Either the second a -olefin is polymerized initially followed by the polymerization of propylene, or propylene is polymerized initially followed by the polymerization of the second a -olefin and thereafter propylene is further polymerized.  In one example, the further polymerization of propylene is followed by the polymerization of ethylene. Second a -olefins exemplified are 3-methyl butene-1, 3-methyl pentene-1, and 4,41-dimethyl pentene-1.  Catalysts exemplified are mixtures of titanium trichloride with ethyl aluminium dichloride or diethyl aluminium chloride.  After polymerization of the second a -olefin the resultant dispersion catalyst and polymer may be washed free of hydrocarbon-soluble materials, stored, and subsequently used with added organo-metallic activator to polymerize propylene. Polymerization may be effected in the presence of hydrogen.

Title: Reduction of thermally induced stress birefringence in a synthetic crystal by control of growth direction
IPC: H01S3/08
Filed: 1971-09-01
Abstract: 1358064 Luminescent materials UNION CARBIDE CORP 1 Sept 1971 [26 Oct 1970] 40698/71 Heading C4S [Also in Division H1] Stress birefringence in a laser crystal is reduced by a suitable choice of the growth direction of the crystal in its manufacture. Fig. 1 shows a Nd doped YAG active medium 10 pumped by a helical flashlamp 12, the resulting thermal gradient in the medium causing stress variations and hence birefringence. When used with a polarizer 15 this results in considerable wastage of output as shown by arrow P L . For a conventional YAG crystal, which is grown in a [111] direction, the birefringence under such pumping is shown in Fig. 6 by the dotted line. This birefringence is not a function of the angle #, i.e. it is constant for all points at a given distance from the medium axis in a given transverse plane through the medium. For crystals grown in the [001] direction the birefringence is as shown by the dotted lines of Fig. 8; the birefringence is greater at some points than at corresponding points of Fig. 6, while in others it is less. If the plane of polarization set by the polarizer 15 in Fig. 1 is vertical in Fig. 8, i.e. coincident with the axis X in Fig. 8, the overall effect of birefringence is a minimum. If the plane is set to coincide with a 45 degree plane as shown by the dotted line marked Polarizer direction in Fig. 8 the overall birefringence is increased. The difference between the [111] birefringence and the maximum and minimum values for the [001] crystal vary with pumping energy (i.e. thermal gradient) as given in Fig. 9 (not shown).

Abstract: 1483536 Making explosives BOFORS AB 25 Sept 1974 [26 Sept 1973] 41780/74 Heading C1D [Also in Division B5] An explosive is screw extruded as strands 14 from a screw extruder, to the inlet 7 of which it is fed as a slurry of powder or granules in water, with a major proportion of the water being removed at a location 11 adjacent the inlet, to accelerate the feed to the extruder. The explosive comprises nitrocellulose, which may also include nitroglycerine and nitroguanidine. Prior to feeding to the extruder, the nitrocellulose may be heated in the water, together with methyl ethyl ketone or ethyl acetate, to agglomerate it to a grain size of 1 mm., with the solvent being partly or completely driven off. The water and explosive is delivered to the screw extruder 1, from a container 5 provided with a feeding screw (not shown) and supplied via a pipe 9 and nozzle 10. The location 11 at which the water is removed comprises a strainer and suction nozzle, through which the water is removed by a pump 12 which recirculates the water to the container 5, via a pipe 13. Water passing along the extruder collects on the screw, and passes centrally therefrom to the extruder die from which it is extruded (as second grade explosive to be re-extruded) from an opening disposed centrally of openings from which the drier explosive is extruded. The strands 14 pass through warm water in a trough (not shown), to a cutter 16 having a water separator 17, and funnel 18 for recycling the water, and the cut lengths are dried in a hot air current. Alternatively the explosive may be extruded and cut by a rotating knife into pieces which are mixed with water and then extruded from a similar further extruder. The extruder, Fig. 3 (not shown), is provided with circulating water cooling of its barrel and screw, and gauges for measuring temperature and pressure along the screw barrel.

Filed: 1972-09-12
Abstract: 1399512 Selective signalling MARTIN MARIETTA CORP 12 Sept 1972 [25 Oct 1971] 42313/72 Heading G4H [Also in Division H4] A plurality of transmitters spaced through a geographical area each transmit the same data signal without transmitter interference by transmitting using mutually-exclusive time periods, e.g. by each using a different time slot in a major data frame. Further transmitters can use the same time slots provided no two transmitters using the same time slot have propagation areas which overlap. In a paging system, the address (identity) of a portable radio receiver to be paged is dialled through the telephone system to a central station which includes a computer which, after validity checks, stores it in a queue (unless it is there already). A message word is constructed from 30 addresses from the queue (or less plus dummy addresses) each in Bose-Chaudhuri code with or without a parity bit, preceded by and separated by various types of sync pattern. The message word is sent to and transmitted by various ones of the transmitters in respective time slots of the major data frame, subject (at each transmitter) to a valid sync check. The transmitters can also transmit in a "tone" mode in which all the transmitters transmit together, apart from fixed relative delays intended to equalize reception times. This mode uses different sync patterns (in part) from the other mode, and the transmitters determine which mode to use from the sync patterns received. Each receiver, if it receives the sync pattern preceding the addresses in a given time slot substantially without error, decodes the addressses in that time slot and then de-energizes for 7 seconds, i.e. until the correspondingtime slot in the next data frame (since each frame is 8 time slots, of one second each). If the receiver recognises one of the addresses, it gives an audible (tone or enunciated message) and/or visual indication. A receiver may correspond to two addresses to indicate origin of the page (e.g. home or office) or degree of urgency, giving different tones (or a steady and an interrupted tone).
