Title: Improvements in or relating to the consolidation of thread coils, particularly of artificial silk
IPC: D01D10/04
Filed: 1931-03-16
Abstract: <PICT:0366772/IV/1> <PICT:0366772/IV/2> <PICT:0366772/IV/3> Thread coils or cakes, particularly of artificial silk, are mounted on an expansible skeleton core, comprising narrow bearing surfaces, and are subjected to treatment with liquids forced from outside to inside through the windings which are thereby bent inwardly between the bearing surfaces of the core.  The coils may be arranged in column form upon the skeleton cores, and several of such columns may be placed on a common support.  As shown in the drawings, the base member 1 of a skeleton core has recesses 2 in which rod-shaped longitudinal members 3 are loosely mounted and disposed about the central bore 4 of the base member to form a polygon.  An elastic member such as a rubber ring 5 is inserted in a groove 6 of the base member and surrounds the rods 3 and pushes them inwardly against the wall of the recesses 2 so as to hold them together and prevent them from moving out of the base member.  A head piece 6<1> with a conical portion 7 is placed on top of the skeleton core after the thread coils have been placed thereon, in order to force the bars 3 apart. The coils of thread are provided with separating members 8 with central openings 8<1> which follow the contour of the longitudinal members in their assembled position.  The flaps 10 between the recesses 9 are bent upwards in order to facilitate axial alignment of the coils.  A cap 13 serves to cover the topmost thread coil of a column.  Several columns are placed on a plate 14 which is inserted in a tub 15, the false bottom of which is provided with a number of holes 17 with bored gaskets 18 registering with the holes 19 in the plate 14.  Liquid is passed by suction through the thread coils from outside to inside.  If the tub is closed at the top, the liquid may be passed through the coils by the application of pressure to the inside of the tub.  Owing to the direction of flow of the liquid, the coils are bent inwardly between the longitudinal members 3.  The deformed coils may be removed from the core and dried without auxiliary supporting means.  After drying, they retain their polygonal shape and the threads may be reeled, wound, or twisted without tangling or shifting of the individual windings of the coils.

Title: Improved circuit arrangement for discriminating between frequencies of alternating or pulsating electric energy
IPC: G01S7/28
Filed: 1942-06-26
Abstract: 601,204. Radio receiving apparatus. SCOLES, G. J., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. June 26, 1942, No. 8855. [Classes 40 (v) and 40 (vi)] A frequency discriminator comprises a relaxation oscillator associated with a biassed valve so that the valve does not pass anode current for one frequency, but does so at a lower frequency. The apparatus can be used for separating signals transmitted at a lower frequency, e.g. 400, from the pulse-modulated, fixed recurrence frequency, e.g. 500, used for radar. Fig. 1 shows a relaxation oscillator comprising resistance R and condenser C and a gas discharge tube V1 to which the signals are applied and an amplifier V2 so biassed and its grid connected through a high resistance to the anode of the tube V1 that the selection is obtained. Resistance R2 is preferably adjustable to control the bias of the amplifier. The relaxation oscillator in the absence of signals may oscillate at a lower frequency than that of the signals so that a low note will be heard in the telephone indicating that the transmitter is not being received. Alternatively, selfoscillation may be prevented by limiting the charge applied .to the condenser C as by arranging a neon lamp in shunt. In a modification, Fig. 3, a separate blocking oscillator V0 is used and the oscillations produced are applied together with the incoming signals to the separate grids of the valve VI. Specifications 535,331, 551,798 and 581,324 are referred to.

Class 100(2) In a doctor blade mechanism for attaining uniform ink passage between the blade and a printing cylinder, the edge of the blade is held in longitudinal resilient engagement with the cylinder by a plurality of pressure members resiliently acting on the blade, the pressure members being guided for movement independently of each other in a substantially perpendicular direction relative to the blade, and their resiliency being produced by a common adjustable resilient pressure medium acting on all the pressure members. A plurality of pressure members 9, 9<SP>1</SP>, Figs. 1 and 2, are accommodated in a slot in a longitudinal flange 8 of a tube 7 supported on arms 5, 6 secured to the shaft 1 of the doctor blade 4. In the tube 7 is a rubber tube 13 connected through a check valve 14 to a compressed air supply and bearing against the pressure members. The tube 7 is placed in position by means of co-operating surfaces 17, 18 and turned through approximately aright-angle by a handle 19 to a position wherein it is locked on the arms and accurately defined by an adjustable screw 23, and wherein the members 9 are aligned with the blade 4 near its end. In operation, the shorter end members 9<SP>1</SP> engage the blade, the members 9 being thus forced some way back into the tube 7. In another form, Fig. 3, the compressed air is supplied to a tube 30, and each pressure member comprises a cylinder 33 extending into the tube 30 and containing a piston 40 protruding therefrom and carrying a pivoted pressure plate 44 for contacting the blade 46. A rubber tube 47 with one end closed is placed over the top of the piston 40, folded upwards inside the cylinder 33 and down and outwards over its edge, so as to form an airtight seal. The effective area of the piston exposed to the pressure is thus the same in all positions of the piston.
