Title: Improved process for producing fibres from alpha-olefin polymers, particularly polypropylene
IPC: D01F6/04
Filed: 1963-04-29
Abstract: 982,630. Making polyolefine fibres. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 29, 1963 [April 30, 1962], No. 16729/63. Drawings to Specification. Heading B5B. Fibres are produced by melt-spinning a crystallizable polypropylene or another alpha olefine polymer and stretching the filaments thus formed in two stages, the first stage consisting in stretching the filaments at a temperature below 105‹ C. to a draw ratio which is from 50% under to 25% over the natural draw ratio. In the second stretching stage (which may, or may not, immediately follow the first stretching stage), the filaments are stretched at a temperature above 115‹ C. but below their melting temperature, e.g. at a temperature between 115‹ and 200‹ C., preferably between 125‹ and 155‹ C. The first stretching stage may be carried out at a temperature between 50‹ and 100‹ C., preferably between 80‹ and 95‹ C. The filaments may consist of predominantly stereoregular polypropylene. The draw ratio in the second stretching stage preferably approaches the ultimate limit beyond which either filament whitening or breakage would occur. The melt extruded filaments after leaving the spinneret and being partially solidified by travelling through cooling air may be cooled in a water bath sufficiently to be completely solidified while under only sufficient tension to move them through the bath without substantially orienting them, and the first stretching stage may take place in a second water bath maintained at a temperature below 95‹ C. The stretched filaments may then be heated to above 115‹ C. and subjected to the second stretching stage while being maintained at a temperature between 125‹ C. and 155‹ C. in a gaseous atmosphere. Specification 813,891 is referred to.

Title: Improvements in or relating to film spool supporting means for photographic cameras
IPC: G03B17/30
Filed: 1941-12-30
Abstract: 546,884. Photographic roll-film cameras. KODAK, Ltd. Dec. 30, 1941, No. 16802. Convention date, July 19. [Class 98 (i)] The film spools in a roll-film camera are held by rollers having portions 22 which engage the spool flanges 23 and frusto-conical or like portions 24 of greater diameter engaging the edges of the leading and trailing strips of the film, which are thus held tightly wound. In the box camera shown, the spool flanges are positioned by the rollers, by the wall 15 of the spool chamber, and by springs 25 which bear on them. Any increase in the resistance to unwinding of the film gives the flanges 23 a tendency to ride upwardly, so causing a counterbalancing diminution in the frictional resistance between them and the wall 15.

Patent GB-739156-A (GB)
Title: Improvements in or relating to treatment of benzene hexachloride
IPC: C07C17/38
Filed: 1952-07-07
Abstract: The gamma isomer is separated from a solution of mixed benzene hexachloride isomers in a solvent from which the gamma isomer crystallizes as monoclinic platelets and which is saturated at a temperature of above 55 DEG  C. with respect to the alpha and gamma isomers by cooling rapidly to a temperature between 55 DEG  C. and 35 DEG  C., holding at this temperature or cooling it within this temperature range for 10 to 100 minutes to cause preferential crystallization of the gamma isomer, then rapidly cooling to a temperature between 10 DEG  and 30 DEG  C.  The process is suitably carried out by extracting a benzene hexachloride mixture with a solvent such as methanol so as to leave appreciable quantities of the alpha and beta isomers undissolved, evaporating the solvent to remove 50 to 90 per cent of the solvent, cooling to 40 DEG  to 50 DEG  C. in less than 30 minutes and preferably in less than 5 minutes, holding the solution at this temperature or slowly cooling within this temperature range for 10 to 100 minutes and cooling to 10 DEG  to 30 DEG  C. to give further crystallization, the crystallization process being interrupted when 60-95 per cent of the equilibrium amount of the gamma isomer is crystallized.  Suitable solvents are lower aliphatic alcohols, aromatic hydrocarbons, halogenated hydrocarbons, esters and ethers.  The solvents may if desired be mixed with a diluent such as water, petroleum ether or pentane. Examples describe the crystallization of benzene hexachloride from methanol, aqueous methanol and benzene to give a product containing an increased proportion of gamma isomer.

Title: Coin dispensing device
IPC: G07D1/02
Filed: 1945-07-11
Abstract: 598,081. Money delivering apparatus. DEHN, F. B. (Mills Industries, Inc.). July 11, 1945, No. 17718. [Class 27] Apparatus for ejecting a selected number of coins from a pile 27 in a container 14 comprises a carrier 24, normally positioned out of alignment with the container, but movable into alignment at the commencement of each operation, whereupon a coin support 17 is lowered stepwise until the selected number of coins have passed down into the carrier, Fig. 5, which then returns to its normal position, Fig. 3, and discharges the coins through an opening 25 to the operator. The apparatus shown has two identical side-by-side containers working simultaneously. The 'carrier 24 of each is mounted at the end of a common slide 16 slotted to admit the supports 17 in the position of Fig. 3 and operable by an electromagnet 28 against a spring 32. The supports 17 are carried by a bracket 22 on a vertical rack 21 adapted to be lowered step-wise by an electromagnet 39 acting through pawl and ratchet mechanism 51, 52 and a pinion 53 meshing with the rack. A toggle switch 63 (see also Fig. 7), actuated by the magnet 39 and in its circuit, causes it to reciprocate as long as its circuit 76, 78 is energised. Selection of the number of coins required is effected by a series of push-buttons 65 closing contacts connected to an arcuate series of contacts 69, and three further contacts 79 and 80 in the case of keys for large amounts. Contacts 69 are normally engaged by corresponding contact fingers 74 on p commutator ring 73 which also has longer fingers 75 for engaging contacts 79, 80. The ring 73 is arranged to be rotated step-wise with the pinion 53 which lowers the support 17. Upon depression of a key 65 the circuit of magnet 28 is closed through the commutator ring so that the carriers 24 are moved into alignment with the coin containers 14. By means of a toggle switch 33 the magnet 28 also closes the circuit of the magnet 39 which thereupon commences to reciprocate, so lowering the coin supports 17 in steps of one coin thickness, and rotating the ring 73 in steps of its contact spacing. When the selected number of coins has been lowered into the carriers, the circuit of the magnets is broken at the commutator ring so that the supports 17 cease movement, and the carriers are returned to their normal position, Fig. 3, and discharge the coins. The coins in the container 14 are then supported by side ledges 15 of the slide 16 pending the return of the supports 17 which is effected by a torsion spring on the shaft 45 of the pinion 53 when a release lever 54 is operated. This also restores the commutator ring to normal.

Abstract: 1,029,019. Semi-permanent stores. J. DONDOUX, M. BASQUE, and Y. LE GOFFIC. April 29, 1964 [June 5, 1963], No. 17768/64. Heading G4A. In a semi-permanent store having cross-points of interrogation and reading circuits 30, 40 (Fig. 1, not shown), inductively coupled at 10, parasitic signals are eliminated by a compensation circuit 50 with no electromagnetic coupling elements, fed coincidently with the interrogation circuits by signals of the same form but opposite polarity or phase. The magnitude of the compensation signals are calculated assuming there are equal numbers of ones and zeros recorded at the cross-points. Printed circuit cards are used with holes punched in the word cards where zeros are required. The reading circuits are connected to a transformer the centre of whose primary winding may be earthed if the spurious signals are symmetrical, or an earthed metal screen 45 may be inserted between the primary and secondary windings if the signals are asymmetrical. In a high capacity memory several interrogation cards associated with reading cards of different groups are connected in series to a point connection of an access matrix (Fig. 2, not shown) and the compensation circuits are similarly connected to a second matrix. The appropriate transistor switches are selected through an address register and decoder to apply sinusoidal signals of opposite polarities to the interrogation circuits and compensation circuits.
