Title: Improvements relating to apparatus for embossing designs upon cloth or the like material
IPC: D06C23/00
Filed: 1928-11-01
Abstract: 324,705. Hudson, G. R. Nov. 1, 1928. Embossing-machines.-An embossing-machine for producing raised designs on silk, velvet, or other textile or like material comprises heated upper and lower platens 8, 14, respectively, each of which can be moved out of the press on horizontal guides to afford access to the operative faces thereof, the lower platen 14 being raised yieldingly to apply pressure to the workpiece, die. etc., supported thereon, after the upper platen has been lowered and' secured in its operative position. Rails 9, yieldingly supported by springs 19 above the fixed bed 7 of the press, carry rollers 10 upon which rest projections 11 on the lower face of the platen 8. A U-shaped member 18, fixed to the rail 9, forms, together with the rollers 10, a guide for the end of the platen 8. A foot-lever 12 is operated to depress the platen 8 to operative position, against the pressure of the springs 19, through a link 22, vertical rod 23 and a spring 24 interposed between a side extension 23<1> of the rod 23 and the member 18. The plate 8 is secured in this position by a spring- pressed pawl 26 which snaps into a groove 25<1> on the rod 23. In order to release the pawl 26, a collar 29, slidable on the main framing, is operated by a hand-lever 31 through links 30 so as to engage and depress the tail of the pawl. The lower platen 14 has similar projections 11 tn the platen normally resting on rollers 10 mounted on the bed 7 so as to be slidable horizontally for inspection. In order to raise the platen 14, an air-cylinder 33 is suitably guided in the bed 7 and has a piston 34 slidable therein connected by a link 35 to an operating lever 16 which has a spring-pressed pawl 36 engaging a toothed sector 37 so as to retain the lever 16 in the position to which it is moved. A weighted lever 39 is provided for withdrawing the pawl 36. A valve 34a, having a vertical movement limited by a stop 34b and guide 34<c> and provided with a small duct 34f, is fitted to the piston 33. When the lever 16 is operated, the piston 34 and the cylinder 33 move upwardly to raise the platen 14, the aircylinder 33 causing the pressure applied to be a yielding one. After the pressing operation is completed, the platen 14 will drop slowly until it rests on the rollers 10 due to the leakage of air through the duct 34f. The valve 34 lifts to allow the piston to fall to its initial position when the pawl 36 is released. A ring 33<a>, having radiating webs 33b and a stud 33c adapted to engage recesses 14a and 14b respectively in the platen 14, is fixed to the end of the cylinder 33 and allows the platen 14 to adjust itself to any unevenness of the upper platen or of the material placed between the platens. The apparatus is more particularly for use in carrying out the processes described in Specification 317,578.
Patent GB-305527-A (GB)
IPC: F16F15/16
Filed: 1928-11-01
Abstract: 305,527. Junkers, H. Feb. 6, 1928, [Convention date]. Flywheels. - In apparatus for damping the torsional oscillations of rotary shafts in which a part rigid with the shaft is coupled to a freely rotatable revolving mass by frictional devices or by dash-pot apparatus, the heat generated in the damper is transmitted to circulating liquid which is cooled by external means. In Fig. 1, a disc 2 is fixed on the shaft and is surrounded by two freely mounted discs 3, 4 carrying heavy rotating masses 6, 7. The disc 2 is provided with braking surfaces 8, 9 which are engaged by corresponding surfaces on the outer discs 3, 4, pressure being applied by means of springs 12. Small radial passages for the circulation of the liquid are machined in the braking surfaces. liquid from the cooler 37 is led through a pump 38, pipe 39, passage 20 in the shaft and radial holes 22, 23 to the spaces between the discs 2, 3, 4 from which it passes between the friction surfaces to the outer passages 26 and chambers 29, 30 formed by annular check plates 31, 32. It then falls into the bottom of the fixed casing 35. Since the points of exit 33, 34 of the liquid from the damper are further from the centre of the shaft than the point of admission, the circulation of the liquid is assisted by centrifugal force. Further assistance can also be obtained by shaping the grooves in the friction faces after the manner of the vanes of centrifugal pumps. The grooves in the faces may be replaced by closed passages in the metal below the surfaces. In Figs. 3 and 4, the circulating liquid also forms the damping medium and is obtained from the crank case of an internal-combustion engine, to the crank shaft of which the damper is applied. The central disc 50 secured to the crank shaft is provided with circumferential and radial partitions forming a number of outwardly facing pockets. The freely mounted revolving mass 58 is carried by two discs 56, 57 having vanes 59 which project into the pockets. Movement of the vanes 59 in the pockets due to vibration, pumps liquid through small gaps 62, 63 in the direction indicated by the arrows. The oil delivered by the usual force pump 74 is led to the bearings of the drilled crank shaft and also to the damper through the passage 91. The oil leaves the damper through the passage 92 and returns to the sump. In a modification having an independent circulating system, the heavy revolving mass is arranged inside the casing and carries vanes which project radially outwards into pockets.

Title: Improvements in or relating to circuits for receiving frequency-modulated oscillations
IPC: H03G11/06
Filed: 1947-12-02
Abstract: 646,997. Frequency modulation. PHILIPS ELECTRICAL, Ltd. Dec. 2, 1947, No. 31851. Convention date, Dec. 4, 1946. [Class 40 (v)] In a frequency-modulation receiver, unwanted amplitude modulation is suppressed by reverse feed-back of the output of an amplitude-modulation detector, this detected output being first amplified by one of the intermediate frequency amplifiers and then fed to a further I.F. amplifier to vary its gain. In Fig. 1, the I.F. wave is fed to the grid of the first I.F. valve 1, and thence to the second I.F. valve 2 to the anode circuit of which is coupled an A.M. detector 5, 6. The detector circuit 5, 6 may also be fed from the output of the valve 1, Fig. 5 (not shown). The detected output is fed back to the grid of the valve 1 where it is amplified and fed forward to vary the gain of the valve 2 in inverse sense to the amplitude variations of the I.F. wave. The smoothed output of the valve 2 passes to a F.M. discriminator 4, which may also receive wave energy through a resistor 16 from the anode of the first valve 1. The functions of the valves 1, 2 may be reversed, the valve 2 amplifying the output from the detector 5, 6 and its output being fed back to the valve 1 to vary the gain, Fig. 2 (not shown). In Fig. 3, the valves 1, 2 and the A.M. detector 5, 6 are arranged as in Fig. 1, but the F.M. detector comprises the coupled circuits 7, 8 and 9, both tuned to the I.F. and connected to a rectifier 10 and load resistor 11. The difference between the outputs across the resistors 6, 11 is applied to the lowfrequency amplifier 12. A further modification, Fig. 4, employs a discriminator of the kind in which two tuned coupled circuits 8, 9 fed from the valve 2 are connected in the respective control-grid circuits of a multi-grid valve 13, the anode current of which varies with the frequency deviation. Amplitude modulation is removed by varying the bias on both grids by a resistor 21 which together with a resistor 20 is connected in the anode circuit of the valve 1 and is therefore the seat of voltages varying with the amplitude modulation of the I.F. wave. The valve 1 may be the mixer valve of a superheterodyne receiver, and the valve 2 the first I.F. amplifier. The suppression of slow amplitude variations of the received wave may be effected by an A.V.C. circuit separate from the control circuits described above.

Title: Apparatus and method for detecting and piecing-up ends down on spinning machines
IPC: D01H13/16
Filed: 1969-06-24
Abstract: 1278961 Piecing arrangements, cleaning machines, signalling PARKS-CRAMER CO 24 June 1969 [24 June 1968] 31925/69 Headings DID and DIF An automatic piecing device is mounted on a travelling pneumatic cleaner which services a plurality of spinning machines. The pneumatic cleaner travels on an overhead electric track to suck lint &c from both sides of a ring and traveller spinning frame (Fig. I not shown).  The piecing device (11 in Fig. 1) is carried supported between the blowing and suction tubes of the cleaner and its photoelectric yarn sensor (79, in Fig. 4), is activated at the start of its traverse of a row of spindles. Yarn breakage at one of the spindles is sensed by the sensor 79 and the cleaner carriage is braked. A timing device is actuated to control the subsequent sequence of piecing operations. A centreing member (120 in Fig. 4A not shown) accurately aligns the piecing up device with the spindle, (Fig. 4). Yarn grippers (126, 127, 166, 167) (which subsequently act on an auxiliary yarn Y-1) are moved forward to the spindle and the carriage carrying these, grippers &c is lowered onto the ring rail (Fig. 5, not shown). The yarn joining operation is then initiated by an upward and downward movement of auxiliary yarn gripper (127) to distend auxiliary yarn Y-1 between the upper and lower grippers (166, 167), this length of yarn being cut below the lower gripper 166 and the grippers then being advanced onto the spindles (Fig. 16). The upper gripper is released and the cut length of the auxiliary yarn is pneumatically knotted with the roving from the drafting rollers (Fig. 17 not shown). One lower gripper is also released and the traveller is threaded onto the yarn by being blown around the ring with a blast of air (Figs. 19, 20 not shown). A second blast of air blows the auxiliary yarn against the bobbin so that it is wound up. At about the same time the yarn grippers are retracted. The carriage carrying the grippers is then fully retracted and raised off the ring rail. The piecing up device centreing member is released and piecing up device again moves along the row of spindles. Counting and signalling ends down after an attempt has been made to piece the yarn may be performed by a process similar to that described in Specification 1267701. The ends down condition is detected by the first yarn sensor 79 and a second photoelectric yarn sensor 80 carried on the piecing up device.
