Abstract: 402,746. Treating fur skins; calendering- apparatus. PANNONIA BARANYBORNEMESITO ES KERESKEDELMI RESZVENYTARSASAG EZELOTT DIAMANT SAMU ES FIAT, 44, Vaci ut, Ujpest, Hungary. June 2, 1933, No. 16020. Convention date, June 4, 1932. [Classes, 42 (i) and 76.] Skins are combed and ironed in a single machine by devices which comb the hairs prior to ironing in a direction at an angle to the direction of ironing. The machine comprises a heated ironing roller 1 having segmental ironing surfaces and combs 3 located in grooves, these combs consisting of pairs of toothed bars 3<1>, 3", which are made to approach and recede from one another by a cam or like device. The movement of the comb-bars is effected by the engagement of rollers 6 mounted upon them with cams 9, 10, 10<1> carried by a cylinder 8 on a fixed shaft 7 about which the cylinder 1 rotates. The roller 1 is heated by burners 11. In an alternative construction the movement of the bars 3', 3<11> may be effected by cam devices external to the roller.

Abstract: 492,407. Valve amplifying circuits. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. June 10, 1937, Nos. 16168 and 16897. [Class 40 (v)] The invention relates to circuits of the kind in which two phase opposed output voltages for application to a push pull amplifying stage are derived from a single input and seeks to avoid the inherent disadvantages of one known arrangement comprising a valve with high resistances in anode and cathode circuits, output voltages being taken from anode-HT negative, and cathode -HT negative. According to the invention as embodied in Fig. 3, the cathode resistance R<1> is made small compared with the anode resistance R of valve 1, the phase-opposed voltages across 4, 6 and 5, 6 being balanced by amplifying the voltage across R<1> in an auxiliary valve 7 without change of phase. The anode load resistance S of the valve 7 is greater than R and the Specification shows mathematically that the condition for balanced output voltages is where g2 is the mutual conductance of 7. Resistance 10 is large compared with R<1> and 9 is an blocking condenser with small impedance at audio frequencies. The condition of balance depends on the characteristic of valve 7 ; in order to prevent replacement of this valve from disturbing this condition, the output circuit may be modified, as shown in Fig. 1, by connecting two equal resistances r1 with a common portion r2 in the control grid circuit of valve 7 It is shown mathematically that, while the condition for balanced voltages is still as for Fig. 3, provided the term r1 + 2r2 is large compared with the right-hand side of equation (10) of the Specification the balance will be almost perfect even if the equation of Fig. 3 is not fulfilled ; r1 and r2 need not be exactly equal and may constitute the grid leaks of following amplifier valves.

Filed: 1960-05-09
Abstract: Carpet yarn, containing at least 25% by weight of regenerated cellulose, is impregnated, either before or after incorporation in a carpet, with a solution containing a protein, a hardening agent for the protein, and a humectant.  An improved handle is thereby imparted to the yarn or carpet, and other properties, such as resilience, and resistance to soiling and abrasion, may be improved.  A preferred protein is gelatin, and specified hardening agents are formaldehyde, glyoxal, sodium cyanate, aluminium or chromium salts and polyepoxides.  Ethylene glycol, glycerin or aqueous calcium chloride may be used as humectants.  Other yarn-treating agents, such as colloidal silicones or wax emulsions may be incorporated in the impregnating solution.  The quantity of solution applied may be such as to deposit 0.01-5.0% by weight of protein on the fibres.  Examples of typical treating solutions are given.ALSO:An impregnating solution for carpet yarn comprises a protein, a hardening agent for the protein, and a humectant.

Class 20 (4) Adjacent edges of panels are connected together, to form e.g. a partition wall, by means of channel sections 6 each of which has a web 7 for attachment, e.g. by dowels 13, or screws, to the edge 5 of one panel, and flanges 8, 9, the bent back limbs 11 of the flanges 9 overlying the flanges 8 to conceal the abutting webs of the adjacent sections. Each panel is composed of two internal layers of fibre board 2 and two external layers of hardboard 3 and may be framed with timber 19, Fig. 5. The panels may also be made of wood wool slab, plaster board, timber, plywood, or glass. The sections may be of metal or plastic, and when they are of extruded metal the space between the flange 9 and the limb 11 is absent. A capping for a partition which does not reach the ceiling comprises a box 15 and a flat steel plate 14, Fig. 4. In a modification the edges of the panels are provided with T-sections, Fig. 5, each section having a web 16 and flanges 17, 18, the flange 17 being slightly longer than the flange 18 in order to form a symmetrical joint. In a further modification angle sections, not shown, are used, the webs of each section being attached to the edge of one panel to contact the adjacent panel, or the sections secured to it and the abutting webs of adjacent sections being concealed. If the panels are not framed with timber the webs 5 of the sections are secured to their panel edges by U-shaped staple elements 20 each of which is let into a slot 21, Fig. 7. Each element is threaded on to a screw 22 which upon rotation draws the U-shaped element on to a block 23 round the screw 22, the ends of the member 20 being splayed to enter the panel.

Abstract: 923,485. Winding yarns; stop mechanism. W. REINERS. May 14, 1959 [June 11, 1958], No. 16565/59. Class 120 (2). A thread winding machine of the kind in which the package is driven by contact with a traverse drum or like rotary member, comprises means to detect the formation of a thread roll on the traverse drum or the like resulting from breakage of the thread and means to arrest the rotation of said drum upon the detection of such thread roll by the detecting means. In the embodiment shown in Fig. 1, the traverse drum 1 is driven through friction wheels 2, 3 and in turn drives package 4. A spindle 9 extending from roller 3 carries a feeler roller 7 which is urged into peripheral contact with drum 1 by spring 8. If the thread F should break and form a band or roll W the roller 7 is moved away from the drum and roller 3 is disengaged from roller 2. In a second embodiment roller 3 is mounted on a pivoted lever and held in contact with drum 1 and with a friction drive roller. The roller 7 is pivoted on a bell-crank lever and, on the formation of a roll W, is caused to disengage roller 3 from its drive means. In a further embodiment the roller 7 is replaced by a feeler lever which on the formation of a roll W is caused to move into the path of an oscillating lever and thereby cause disengagement of roller 3 from the drive roller. In this embodiment a thread feeler is provided so that if the thread breaks but does not form a roll on the traverse drum the feeler lever end engages the oscillating lever to cause disengagement of the drive. In another embodiment a light ray parallel to the periphery of the drum is used to detect a roll W formed thereon and cause disengagement of the drive. Alternatively a dynamometer in the drive to the traverse drum may be used to detect the formation of thread roll W and cause interruption of the drive. A signal or warning device may be provided in conjunction with the stopping device.
