Title: Improvements in or relating to combing machines for wool and other textile fibres
IPC: D01G19/02
Filed: 1966-12-02
Abstract: 1,119,900. Combing machines. UNISEARCH Ltd. 2 Dec., 1966 [9 Dec., 1965], No. 54035/66. Heading D1N. A combing machine for textile fibres comprises feeding mechanisms 11 arranged on a "feed circle" for intermittently forwarding slivers 12, a rotating comb such as a pinned drum 24 to comb the forward ends of the sliver, means to move the rotating comb relative to the feed mechanisms to comb the sliver ends in turn and means such as plates 22 (see also Fig. 3 not shown) to clamp each sliver adjacent its forward end while the forward end is combed. The combed forward ends of the slivers are drawn off by means such as a rotating circular arrangement of clamping jaws 34 which moves bodily relative to the feeding mechanisms and pulls the fibres through a comb 31 (see also Fig. 3) which is inserted through the fibres for the drawing off action and then conveys the fibres to means such as rollers 38 which carry away the fibres released by the draw off means and form them into slivers. In Fig. 3 not shown a sliver (12) is fed by a smooth roller (13) and a fluted roller (14) to a porcupine roller (16) and then to a plate (17) against which the fibres can be clamped by the plates (22). The feed is intermittently operated by a hydraulically activated lever and ratchet device. The axis of combing drum 24 is arranged at an angle to the plane of the feed circle and the magnitudes of its rotational speeds about its own axis and about the axis of the feed circle can be arranged so that the fibres are combed with no lateral movement: similarly the rotational speeds of the draw off ring about its own axis and about the axis of the feed circle can be so arranged that the fibres are drawn off radially of the feed circle. The pins on comb 24 can be of varying length. A brush 29 is provided to clean each comb 24. Plates 22, combs 31, clamps 34 and the drive for the feed mechanisms are operated in the required relation by individual hydraulic cylinder devices. In Figs. 4, 5 not shown, comb cylinders 24 are replaced by a circular, horizontal arrangement of upper and lower pinned segments (42, 43) which rotates about its own axis and also about the axis of the feed circle. The upper and lower segment are brought towards each other adjacent the feed circle to penetrate and then comb the fibres, the combing action being substantially radial of the feed circle. When the segments open the waste matter therein is removed by air jets. The drawing off arrangement of Fig. 2 may be replaced by a pair of horizontal rubber or like rings which are brought into fibre clamping and releasing relation in the same way as the clamps of Fig. 2: alternatively a ring of vertically arranged roller pairs is provided.

Abstract: 1,262,986. Preparation of tricyclohexyltin halides. M & T INTERNATIONAL N.V. 4 Nov., 1969 [4 Nov., 1968; 16 April, 1969], No. 54060/69. Heading C2J. A process for preparing a tricyclohexyltin halide, the cyclohexyl rings of which may be inertly substituted, comprises reacting an organotricyclohexyltin with a tin tetrahalide, usually in equimolar quantities at 0-120 C. in a solvent. Specified inert substituents are methyl, isopropyl, n-butyl, t-butyl and phenyl groups. The organo group in the first reactant may be alkyl, alkenyl, cycloalkyl, aralkyl, aryl or alkaryl and may be inertly substituted, many such groups being specified. The first reactant is usually obtained by reacting an organotin trihalide and a cyclohexyl magnesium halide in a hydrocarbon solvent, the organotricyclohexyl tin being recovered by hydrolysis of the reaction mixture with aqueous citric acid. The organotin trihalide may be prepared by reacting a tetraorganotin with a tin tetrahalide. In the examples, tricyclohexyltin chloride is prepared from (a) SnCl 4  and C 6 H 5 Sn(C 6 H 11 ) 3 , the latter being prepared from C 6 H 5 SnCl 3  (from SnCl 4  and (C 6 H 5 ) 4 Sn) and C 6 H 11 MgCl and from (b) SnCl 4  and C 4 H 9 Sn(C 6 H 11 ) 3 .

The magnet is a permanent bar magnet and the magnetic member 6 is secured to an end thereof. Alternatively the magnetic member 6 may be secured to the periphery of the rotor outside of the magnetic circuit of the rotary machine on a conductor such as the short circuiting ring 4 of a squirrel cage motor, a coil head of a wound rotor, a synchronous motor inductor or the collector plate of a D.C. motor.

Abstract: 1,161,816. Molecular sieves. UNIVERSAL OIL PRODUCTS CO. 12 Dec., 1966, No. 55476/66. Heading C1A. [Also in Division C5] Shaped particles of silica or silica-alumina, preferably calcined, are first aged with a solution containing sodium cations and anions selected from hydroxyl, silicate and aluminate and then further aged, after the addition to sufficient sodium hydroxide to bring the mole ratio of sodium to silicon in the total mixture to between 0. 6 and 3, until a portion of the shaped particles is converted to a zeolite containing the faujasite structure and retaining the size and shape of the original particles. The first ageing step may be carried out at a Na to Al mole ratio between 1 and 1.6 for 1-48 hours at 20-120‹ C. in a treating solution containing both sodium aluminate and hydroxide. The second ageing step may be carried out at 40-120‹ C. for 5- 100 hours. The zeolite products having a Si to Al mole ratio between 1 and 3, a substantial proportion of pores of 6 to 15 Angstroms, and an X-ray diffraction pattern such as shown at Example 1. Catalyst carriers having areas of high electric charge are made by (a) decationizing the zeolite by ion exchange of the sodium with ammonium ion and heating at 425- 575‹ C. to remove the ammonium ion, thereby leaving up to 90% of the aluminium containing tetrahedra no longer associated with sodium or ammonium ions, or (b) ion exchanging the Na with divalent Ca, Mg or Be cations to displace at least 30-50% of the sodium cations. In Example 2 a combination of both methods (a) and (b) is used.

Title: Automatic flash amount control arrangement for a camera

Abstract: 1356042 Controlling exposure by flash ASAHI KOGAKU KOGYO KK 30 Nov 1971 [5 Dec 1970] 55610/71 Heading G2A In a flash control arrangement for a camera, the light reflected from an object after a preparatory flash is detected and memorized and an ensuing main flash is terminated when this light reflected from the object reaches a predetermined relationship with the memorized signal. Flash section 101 is actuated by a shutter release lever and the reflected light 106 is reflected out of the taking light path to detector 112 and the signal produced is integrated and stored. When this signal reaches a value sufficient to give an adequate exposure for the film used then the preparatory flash is stopped. A detector 122 also directly monitors the flash and the signal produced is integrated and memorized. Synchronously with shutter opening after the -preparatory flash, the main flash is actuated and the object recorded on the film, the detector 122 again directly monitors the flash and the signal is integrated and compared with the memorized signal from the preparatory flash. When the two signals are equal the main flash is stopped and the shutter closed. Mirror actuation Mirror (64) Fig. 3 (not shown) is actuated from the light path by removal of lever (66) from driving lever (52). The latter rotates anti-clockwise and pin (61) of driving lever (60) traverses the abutting surface (57') of the link (57). When pin (61) disengages the lever (60) swings clockwise and pushes pin (65) and the mirror (64) upwards. This actuation switches contacts (5, 5', 47, 47'). The time delay in actuation caused by movement of pin (61) on (57') allows for diaphragm pre-setting.
