Each lasting assembly B 1  and B 2  includes a toe pad 6 1  or 6 2 , a heel rest 46 1  or 46 2  and a pair of wipers 8 1 , 9 1  or 8 2 , 9 2  and can swing about a cross shaft 57 between a pulling over position (B 1  is in this position in the drawings) and a lasting and trimming position (occupied by B 2  as shown). The trimming assembly T includes a rotary wire brush 13 which brushes the lasting margin across the wipers in a radially outward direction. The brush 13 is mounted on a shaft 15 which can rotate in an arm 34 which is pivoted to a shaft 35. The shaft 35 is carried by an extension of a slide plate 28 which is moved lengthwise of the shoe by a piston and cylinder device 32. The brush is guided around the lasting margin by a template 16, the shaft 15 being urged into contact with the template 16 by a piston and cylinder device 36. The shaft 15 is rotated by a piston and cylinder device 41 to maintain the brush 13 so that it operates in a radially outward direction. In a modification (not shown) the trimming device may take the form of a pair of trimming knives. The machine operates as follows:- a shoe assembly is placed in the machine at the pulling over station at which the pulling over assembly A and lasting assembly B 1  are in juxtaposition and is pulled over by the grippers 55. The wipers 8, 9 are then moved to an intermediate position in which they just start to move over the edge of the insole, thus clamping the upper, and the toe pad 6 and heel rest 46 are moved into position. The grippers 55 then release the upper and the lasting assembly B 1  is then moved to its trimming and lasting position where the lasting margin is trimmed by the brush 13 and the wipers complete their wiping operation. During this trimming and wiping operation the second lasting assembly B 2  is moved to its pulling over position and the pulling over assembly A is moved transversely in the machine to be in juxtaposition with it and a second shoe assembly is pulled over. This cycle is repeated, one shoe assembly being pulled over while another assembly is lasted.

Filed: 1925-10-27
Abstract: 264,918. Columbia Graphophone Co., Ltd., and Mitchell, F. A. Oct. 27, 1925. Gramophone pick - ups; loudspeakers; magnetic instruments. - A sound-reproducing device comprises a stylus-operated diaphragm or equivalent vibratory member, a supporting-frame for the latter, and an actuating stylus-bar pivoted on the frame, the device being characterized in that the frame for the diaphragm &c. is itself pivoted to a supporting- member (such as a part connecting with a tone-arm) on an axis located between the pivotal axis of the stylus-bar and the region of maximum vibratory movement of the diaphragm or equivalent. Fig. 1 shows the application of the invention to a gramophone sound-box, which may, however, be adapted for use in a loudspeaking telephone. The diaphragm D is mounted in a case or frame C which is pivoted at H to a tone-arm connector T. The pivots, which in the construction shown are pins or balls mounted in lugs C<3>, lie on a line which is approximately parallel to the axis of the stylusbar pivot P, and lies between that axis and the region W of maximum vibratory movement of the diaphragm. The part of the case C remote from the stylus-bar pivot is resiliently secured to the member T by means of a pin E, engaging small compression springs B, B<1> which tend to maintain the case in a relatively constant position on the connector. A rubber &c. cushion A makes the joint between the back of the case C and the part T sound-tight. Modifications in the pivoting-devices are described. Fig.. 9 shows an electrical device for use, in conjunction with a valve amplifier &c., for reproducing from records. The diaphragm D<1> in this instance forms the soft iron armature of a magnet K, and when vibrated generates currents in coils J. The diaphragm casing C is pivotally connected by a spring H<3> to the supporting casing T<1>, which encloses the magnet. A modified form of electric reproducer is shown in Figs. 10 and 11. The vibrating armature consists of a bar D<2> pivoted at P to a frame C<2>, which is itself pivoted at H to a member T<2> adapted to be connected to the tone-arm or equivalent. Screws E and springs B hold the frame in a relatively constant position. The connector T carries the magnet K and coil J, and an additional magnetizing coil 0 is provided. Magnet poles K<1> on one side of the armature are of opposite polarity to those K<2> on the other side, and the changes in flux caused by the vibration of the armature induce corresponding currents in the coil J.

Title: Improvements in or relating to cooling arrangements for nuclear reactor fuel elements
Inventor: FOLL JEAN LE
IPC: G21C15/04
Filed: 1960-08-03
Abstract: 955,425. Nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 3,1960 [Aug. 13,1959; April 6, 1960], No. 26940/60. Heading G6C. A casing 1 of a nuclear fuel element is provided with transverse fins 2 and deflection surfaces which cause the cooling fluid to be led transversely into the circular channels between the fins. The fuel element may be provided with four longitudinal openings 19 in a cover 5 which surrounds the fins 2 and by scoops 16 mounted on shoulders 17 over two opposite longitudinal openings 19 and facing upstream to act as inlet orifices, the two remaining longitudinal openings 19 acting as outlet orifices, as in the embodiment illustrated in Fig. 6. In the embodiment shown in Fig. 9, blades 22 are arranged so as to form transverse chevrons 23 which are supported on the edges of the fins 2. The principal flow of cooling liquid is in the direction of the arrow 24 and since the angle of inclination of the chevrons 23 to the outer circumferential surface of the fins 2 increases in the same direction, the pressure is lower in the zones 25 than in the zones 26 and transverse currents are set up between the fins 2. In the modification shown in Fig. 11, the same result is obtained by progressively increasing the size of the blades 22 in the downstream direction. In a further embodiment (Fig. 16), the deflection surfaces have a plane triangular or "delta" form and comprise vanes 27 on either side of a backbone 28. There may, for example, be four such backbones 28 arranged symmetrically around the outer circumference of the fins 2. The vanes 27 are inclined to a plane tangential to the fins 2 and the corresponding backbone 28 at an angle the sine of which is preferably equal to or slightly greater than the ratio of the width of the spaces between the fins 2 to the sum of the space width and the fin thickness, i.e. at an angle of 30 degrees where the fins 2 are spaced apart at a distance equal to their thickness. The principal flow of cooling fluid is shown by the arrow 30 while the arrow 31 represents the path of a portion of the same fluid deflected by the vanes 27. The various deflection surfaces described are suitably made from graphite or other material of low neutron absorption.

Abstract: 535,261. Treating textiles with liquids ; cleansing compositions. BARTLETT, R. G., SIDDLE, F. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 2, 1939, No. 26999. [Class 15 (ii)] [Also in Group III] The textile fabrics of articles of apparel or articles for furnishing are. endowed with increased body, fullness or stiffness by impregnating them with an organic liquid used by dry cleaners, or a mixture of such liquids, in which is dissolved a glycerol ester of a natural resin, e.g. an ester gum, copal ester gum, or ester copal, or a mixture of such esters. The organic liquid is removed by volatilization. The process is carried out simultaneously with or subsequently to a dry cleaning process. The ester gums employed are those obtained by esterifying rosin with glycerol; the ester copals are obtained by esterifying a natural copal with glycerol; the copal ester gums are obtained by esterifying a mixture of a natural copal and rosin with glycerol. Esters of low acid value and high melting point are preferred, e.g. ester gum of melting point 85-90‹C. and acid value of 5 mgs. KOH per gram. The article of apparel or of furnishing may be immersed in the treatment liquid, removed, squeezed or centrifuged to remove excess of solution, and then dried so as to volatilize the residual organic liquid. A solution containing 0.25-2.0 per cent. of the ester may be used. In examples, raincoats of cotton gabardine, cotton casement fabrics, Botany wool serge fabrics, upholstery slub fabrics woven from mercerized cotton warp and cotton weft, cotton-backed viscose rayon sateen fabrics, and cotton gabardine fabrics are treated with solutions of copal ester gum, ester copal, and ester gum in trichloroethylene, white spirit, benzene, and carbon tetrachloride. Specification 402,513, [Group III], is referred to.

Title: Improvements in or relating to a process of making leather-rubber material
IPC: C08L7/00
Filed: 1934-09-21
Abstract: In the manufacture of material of leather and rubber by mixing leather fibres with an aqueous dispersion of negatively charged rubber particles, the pH value is maintained below 7,8, e.g. between 4,2 and 7,8, during the mixing operation.  A small amount of a di- or trivalent cation material, e.g. zinc chloride or aluminium sulphate may be added to the leather some time before the latex.  The pH may be maintained by addition of acid, and an acid material such as aluminium sulphate or acetic acid may be added after the latex to complete its precipitation.  The latex may be alkaline, in which the ammonia content may have been reduced by air-blowing or treatment with formaldehyde or silica gel, or may be acid, prepared for example as described in Specification 288,268, [Class 70], and may be natural or artificial, normal or concentrated, vulcanized or unvulcanized. Other constituents, such as cellulose from cotton or wood pulp, colouring matter, zinc oxide, vulcanizing agents or accelerators, or anti-oxidants may be added.

Abstract: 1531294 Battery testing COMPAGNIE EUROPEENNE D'ACCUMULATEURS SA 30 June 1976 [30 July 1975] 27178/76 Heading G1U The state of health of a battery (as opposed to its state of charge) is determined by fully charging the battery and by observing how rapidly its open circuit voltage drops to a stable value. A typical lead-acid cell in good condition will have an open circuit voltage of about 2.3V when just charged. This voltage MA, Fig. 1, will drop to a stable value of a little over 2.1V after about 10 hours. However, for a defective cell A such as one having an internal short passing about 100mA, the stable voltage is reached more quickly. This phenomenon is exploited in the present invention to test new, just charged, multicell batteries. In the preferred embodiment Figs. 3 and 4 (not shown) the open circuit voltage of each cell of a just-charged multicell battery is compared with the average cell voltage, and if the difference exceeds a pre-set amount, for example after 1 hour, the cell in question is judged to be defective.

Abstract: 1322041 Colour television MAGNAVOX CO 5 June 1970 [6 June 1969] 27373/70 Heading H4F In a colour television system wherein a filter having a set of parallel (minus blue) encoding strips and a set of parallel (minus red) encoding strips set at an angle to the blue strips is used to spatially modulate a colour image before it is scanned at a camera tube, the disposition of the filter and the spacing and direction of the scan lines are such that the amplitude modulated carrier signals for the red and blue components have the same carrier frequency, and each has a constant phase relation from line to line, which is different for each carrier signal. As described, one signal is in phase from line to line and the other signal is 180 degrees out of phase. A third colour (green) is passed by the filter without spatial modulation, so that overall a signal similar to a PAL signal results. At a receiver the entire signal is passed via a delay line as a luminance signal to the cathode of a C.R.T. It is also delayed for one line period and added to and subtracted from the undelayed signal at a centre tapped transformer (118) to provide R and B signals, and also passed through a low pass filter to provide a limited bandwidth luminance signal - Y. By matrixing the latter three signals, there colour difference signals are formed and passed to the grids of the C.R.T. In the colour filter, the two sets of strips may have unequal or equal pitches and are correspondingly unequally inclined to the line scan direction or equally inclined with opposite slope. The encoded image may be recorded on monochrome film which is subsequently scanned. The filter may be disposed away from the camera, e.g. with a lens interposed, or contiguous the face of the camera tube (a fibre optic plate may be interposed) or the monochrome film.
