Abstract: 1,264,351. Poly-γ-methyl glutamate-polyurethane films. AJINOMOTO CO. Inc. 30 April, 1969 [1 May, 1968], No. 22137/69. Heading B5B. [Also in Divisions C3 and D1] Films of an optically active poly-γ-methyl glutamate (PMG) chemically modified by a polymer having terminal isocyanate groups are prepared by casting from a solution in which the modified PMG is dissolved in a solvent, one component of which is a chlorinated aliphatic hydrocarbon and the other component is a water soluble organic solvent containing no active hydrogens and of a higher boiling point than the chlorinated hydrocarbon. The solution is spread on a substrate and the chlorinated aliphatic hydrocarbon is allowed to evaporate leaving a gel which is coagulated by immersion in a bath of which water is a major component, whereby the residual water-soluble organic solvent is removed. The modifying polymer is any polymer having terminal hydroxyl groups to which a diisocyanate may be added to form a polymer having terminal isocyanate groups or a polyurethane having terminal isocyanate groups. Exemplified PMG modified polymers are poly-γ-methyl-L-glutamate reacted with (i) a polyester made from adipic acid, ethylene glycol and propylene glycol and subsequently reacted with naphthalene 1,5 diisocyanate; (ii) a polyethylene glycol reacted with methylene bis-(4-phenylisocyanate); and (iii) a reaction product of tolylene diisocyanate and trimethylol propane. The Specification contains an extensive list of solvents. Exemplified solvents are mixtures of (i) 1,2-dichloroethylene and N,N-dimethyl formamide; (ii) γ-butyrolactam and methylene chloride; (iii) chloroform and ethyl acetate; and (iv) 1,2-dichlorethane and γ- butyrolactam. In Example V, carbon black is present in the casting solution. If desired high molecular weight rubbers and resins, plasticizers e.g. dioctyl phthalate, chlorinated polyphenyls and paraffins, and pigments e.g. titanium dioxide and carbon black, may be incorporated into the casting solutions.

A wall plug which may be of metal or plastics material is provided with a tubular sleeve portion 10 and a flange 11 which is spaced from the sleeve portion 10 and connected to one end thereof by one or more breakable webs 13. The flange 11 may be arranged to overlap the end of the sleeve portion 10 (Fig. 8, not shown) or to be spaced radially from the peripheral surface thereof. In the case of a plurality of webs 13, the webs are circumferentially spaced around the sleeve portion 10 and each may extend from an end surface of the sleeve portion or from the peripheral surface thereof in which latter case the webs when broken form projections on the peripheral surface of the wall plug to prevent rotation of the wall plug in a hole when being used. In the case of a single web (14) (Figs. 3, 4, not shown), the web may form an annular groove between the flange 11 and the end of the sleeve portion 10.

Abstract: 1289563 Cigarette-making appliance GIZEHWERK GmbH 24 Aug 1970 [9 Sept 1969 2 March 1970] 40666/70 Heading A2C A device for filling a tube of cigarette paper 24 with tobacco 29, comprises a casing 1, a slide 4 having a tobacco chamber 10 formed therein, a clamp 6 for holding one end of the paper tube 24 on a nozzle 5 which communicates with the chamber 10, and a compression plate 7 mounted on the slide 4. A guide tongue 9 is mounted within and fixed to the casing 1 by means of a holding piece 23 and screws 12 which latter pass through an elongated slot 15 in the base of the slide 4. In use, tobacco is placed in the chamber 10 and is compressed by lowering the plate 7 which action also causes a cam 26 on the plate 7 to secure a paper tube 24 placed on the nozzle 5. The slide is then moved to the right, as viewed in Fig. 3, to draw the tube 24 around the compressed tobacco 29 and the guide tongue 9. The clamp 6 is released just before this movement is completed, and the slide is then returned to its original position to withdraw the tongue 9 from the now filled tube 24 and eject the completed cigarette. As shown in Fig. 2, the device may include a storage compartment 11 for paper tubes and tobacco. A second embodiment, Figs. 14-20 (not shown) differs mainly in the provision of a clamping piece (44) for the paper tube (35) formed on resilient material such as rubber, and in the provision of a locking catch on the hinged compression plate (37).

Abstract: 1319581 Angular bending R E BENTON 20 Aug 1970 [26 Aug 1969] 42540/69 Heading B3E Apparatus for bending an elongate workpiece comprises a drive member 12 which is mechanically interconnected with a first bending member 14 such that movement of the drive member initially causes the first bending member to clamp the workpiece between adjacent portions of the first bending member and a second bending member 16 and then causes the portions to draw forward the workpiece held therebetween to bend it around the second bending member 16. In the embodiment shown in Fig. 2 a carrier 22 has a pin 20 mounted in a track 26 of a cam 24 so that rotation of the cam by the drive shaft 12 causes the carrier 22 and hence the bending member 14, to move radially inwardly to clamp the workpiece between the two bending members. The movement of the pin 20 relative to the cam is stopped by the end of the track 26 after which continued rotation of the drive shaft 12 causes the two bending members to rotate and effect the bending of the workpiece. In the embodiment shown in Fig. 4 the carrier 22 is attached to one end of a link 38 having a lost motion, the other end of the link being eccentrically mounted on the drive shaft 12.

Abstract: 1344152 Radio navigation STANDARD TELEPHONES & CABLES Ltd 13 Aug 1971 38108/71 Heading H4D A. pulsed hyperbolic radio navigation system. includes a master transmitter M and a slave transmitter S each emitting on a different frequency a. pulse of unmodulated energy, the pulses from each transmitter are of equal duration T, T is not less than twice the propagation time between M and S, synchronizing means at S is responsive to the pulses emitted by M to cause the S-pulses to be emitted with a delay of T/2 relative to those emitted by M, and a receiver determines the relative time positions of two overlapping pulses received from M and S. The position-line determination may be obtained by measuring (i) the total extension between the start of M pulse and the end of the S pulse; or (ii) the amount that the M and S pulses overlap; or (iii) the amount that the M pulse is not overlapped by the S pulse; or (iv) the amount that the S pulse is not overlapped by the M pulse. In one receiver the detected S pulse gates the M pulse to a digital counter, Fig. 3 (not shown). To reduce bandwidth the emitted pulses may be shaped, Figs. 4, 5 (neither shown); a receiver is then provided with automatic gain control followed by a bottom clipper and limiter. A long time constant averaging counter reduces the effects of noise, Fig. 7 (not shown). In another receiver embodiment the clipped M and S pulses are detected and then added, and after further clipping are fed to a voltmeter, Figs. 8, 9 (neither shown). Position-fixing, Figs. 10, 11, 12, 13.-A chain may be as shown in Fig. 10 with transmissions as depicted in Fig. 12. Each master station pulse is preceded by pulse-width coded pulse K to actuate the corresponding slave station S and the appropriate receiver channel, the slave stations transmitting on a common frequency and transmitting sequentially, Fig. 11. In the receiver a decoder, Fig. 12, receives waveform Fig. 13A from. the master station: 65% threshold detectors determine which of the K pulses has been detected. Monitoring.-A distant receiver at known co-ordinates may be provided, with feedback to the transmitters. Multiple-chain working.-Vestigial side-band transmission may be adopted. If an obstacle-reflected wave can be made to alternate betweenin-phase andout-of-phase relationships over a number of successive pulse envelopes; the average count at the receiver will be the more accurate the longer the reflexion path length iscompared with the direct path: to achieve this each successive transmitted pulse may be commutated into a ring of stationary aerials, master and slave stations simultaneously commutating on to the same relative aerial.
