Abstract: 1,160,234. α-Olefin block copolymers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 4 Oct., 1966 [6 Oct., 1965], No. 44302/66. Heading C3P. Elastomeric block copolymers have the general formula A-B-A, in which each A is an homopolymer block of an α-monoolefin having 2 to 8 carbon atoms per molecule, each block A having an average molecular weight of 8000 to 100,000, and B is an elastomeric random copolymer block of at least two α- monoolefins, having an average molecular weight of 35,000 to 500,000, the total block A content being 10 to 50% by weight of the block copolymer. The copolymer may be obtained by hydrogenating a block copolymer in which each A is an unbranched polymer block of a conjugated diene having 4 to 8 carbon atoms per molecule, and B is a branched homopolymer block of an alkyl-substituted conjugated diene. The block copolymers may also be obtained by the direct sequential polymerization of the suitable α-monoolefins using a titanium or vanadium-based Ziegler catalyst. The preparation of the diene copolymers is effected by means of lithium alkyls by either a sequential method or a coupling method. The block copolymers may be moulded and compounded with asphalt, wax, polystyrene, polypropylene, polyethylene, natural rubber, polyisoprene, polybutadiene, α-olefin random copolymers, or poly - (vinyl aromatic hydrocarbon)/poly- (conjugated diene)/poly - (vinyl aromatic hydrocarbon) block copolymers. In the examples: (1) the sequential polymerization of butadiene and isoprene using a butyl lithium catalyst is described, (2) the coupling process is used for the polymerization of butadiene and isoprene using dibromoethane as coupling agent, (3) the polymer of (1) is hydrogenated using a nickel acetate/aluminium triethyl catalyst, and (4) a polypropylene/poly-(ethylene propylene)/polypropylene polymer is prepared using TiCl 3 -Al(C 2 H 5 ) 2 Cl catalyst and a polyethylene/poly - (ethylene - propylene)/polyethylene polymer is prepared using a vanadyl diisopropyl salicylate/Al(C 2 H 5 )Cl 2  catalyst.

Title: Colar energy conversion systems
IPC: F24S23/79
Filed: 1977-10-27
Abstract: A solar energy collection and conversion system in which a cassegrain minor system (31, 33) is rotated about a diurnal axis, which axis is adjusted for seasonal variations in the incidence of the sun's rays on the earth's surface. Along the diurnal axis used for rotation of the collection system an elongate cavity (11, 13) filled with translucent or transparent fluid material is used for direct absorption of the sun's rays. This is accomplished by providing the wall of this cavity (11, 13) with highly reflective surfaces so that substantially all of the incident solar energy is absorbed directly by the fluid medium and only an insignificant portion is absorbed by the cavity walls (11, 13). The fluid within the cavity may be maintained under extremely high pressures and temperatures in order to utilize this fluid as a heat storage medium. Such heat storage is facilitated by apparatus (175, 179, 187, 197) which permits a change in the volume of the reflective cavity (11, 13) in response to the temperature or pressure of the fluid within the cavity.

Abstract: 1,057,580. Photo-electric investigation of quantum systems. VARIAN ASSOCIATES. Nov. 4, 1964 [Dec. 26, 1963], No.45019/64. Heading G1A. [Also in Division H3] Atoms of sodium vapour in an absorption cell 16 are optically pumped by light from a sodium lamp 10 pulsed at the Zeeman frequency or a sub-multiple thereof, the light passing to the cell through a circular polarizer 17, and the cell being arranged in a steady magnetic field H 0  and a R. F. magnetic field H 1  in the same direction produced by the excitation of a resonant cavity 18 at a hyperfine frequency, e.g. 1772 Mc/s. The cell may be used to regulate the frequency of a crystal oscillator 24 the output of which is phase modulated in unit 26 at 10 c/s and synthesized and/or multiplied up to the hyperfine frequency. Light passing through the cell is detected by a photo-cell 36 feeding a filter 38 and amplifier 40. A detector 41 recovers the 10 c/s and 20 c/s signal components, the latter being rejected by filter 43 and the former detected by detector 42 which provides an error signal to a servo-amplifier 44 controlling the tuning of oscillator 24.

Title: Compressive strength tester for tablets
IPC: G01N3/40
Filed: 1971-09-28
Abstract: 1336056 Compression testing HEBERLEIN & CO A G 28 Sept 1971 [14 Oct 1970] 45071/71 Heading G1S In an apparatus for compression testing pharmaceutical tablets in which the tablets 6 are compressed between a measuring slide 5 and a slide 1 reciprocated by an electric motor 2 working either through an eccentric cam arrangement 20, 21 Fig. 1 or a rack and pinion (30), (31) Fig. 2 (not shown), the slide 5 is connected either via a knife edge 22, intermediate piece 23 and needle bearing 24 Fig. 1 or via a steel band (28) Fig. 2 (not shown) to a pendulous counterweight 4 which is connected via a cord 8 guided by rollers 9, 10, 11 to an engaging means 14 such that on compression of a tablet the means 14 moves a drag pointer 16, fastened to cord 15 wound around rollers 40, 41 over a linear scale 17 to indicate the force acting on the tablet and hence its compressive strength. If the pointer is 16 is magnetically armed or made of magnetic material, two hall generators can be appropriately positioned on the scale 17 to sense whether the strength of the tablet is within predetermined tolerance limits. The apparatus is preferably controlled automatically by a circuit as shown in Fig. 3 powered by a mains supply unit 60. The switches are initially in the positions shown so that when the apparatus is switched on the switch 47, operated by slide 1, connects terminal R of the motor 2 to earth via a contact of relay 61, thereby starting the motor to retract the slide 1 until it tips switch 47 to cut off the motor and connect the winding of relay 62 to earth. On operation of start switch 49 this winding is energized to pull in its contacts, the upper set serving to hold the relay. The lower set of contacts connects a setting motor 43 in circuit so that the drag pointer 16 is returned to a zero position. Since the cords 8 and 15 are electrically conductive, when the pointer 16 reaches its zero position in which it contacts engaging means 14, contact is made through sliding contacts 52, 53 and the winding of relay 61 is energized. Terminal V of motor 2 is thus energized to thus advance slide 1 and trip switch 47 to cut off motor 43. On failure of the tablet, the drag pointer 16 remains in its last position but the counterweight 4 moves the engaging means 14 back thereby interrupting contact between the means 14 and the pointer 16 and causing the motor 2 to retract the slide. Guide roller 41 may be connected to a potentiometer to provide a remote read-out, either on an analogue recorder (50) or a digital printer (51).
