Title: Improvements in a machine for applying adhesive to web material
IPC: B05C1/08
Filed: 1939-05-12
Abstract: 527,071. Coating webs; printing. AMERICAN CAN CO. May 12, 1939, No. 14198. Convention date, May 19, 1938. [Class 140] [Also in Group XVI] A machine for applying a pattern of fluid thermoplastic adhesive to a web comprises a receptacle for the adhesive, heating means therefor, a rotable intaglio roller for transferring adhesive from the receptacles to the web, and a movable carriage for the roller arranged to allow the roller to be moved in and out of the receptacle. As shown a web A is fed by pairs of feed rollers E rotated in unison through the adhesive applying unit in which a pressure roller F presses the moving web against an intaglio roller G, the web being tautened by passage over the idler roller H. The intaglio roller G rotates in a heated bath 51 containing fluid thermoplastic adhesive, excess adhesive being removed from the intaglio roller by the doctor blade J. The idler roll H, pressure roll F and intaglio roller G are mounted in a carriage 63, Fig. 9, which is locked in the operative position by latches 70, and which can be swung back, after disconnecting the hooks 195 of the doctor positioning device 201, 196, 198, to expose the rolls for cleaning. As shown the intaglio and pressure rolls G, F are hollow and constructed for the circulation of heating and cooling media respectively, the bearing for these rollers also being constructed for the circulation of a cooling medium. An auxiliary motor 161 is provided for continuing the rotation of the intaglio roller in its bath of adhesive at a slow speed when the normal operation of the machine is suspended, timing means' being also provided to accelerate to full speed in phase with the remainder of the machine when the machine is restarted, the web material being brought against the roller at the proper place to continue application of the pattern. The pressure roll F is held in position when the machine is running by means of a pressure block 236 disposed in slideways 223. The blocks carry cam rollers 242 which engage wedge cams keyed to a cam shaft 245 which is held under torsional force by springs. In normal operation the torsion springs are held against rotating the cam shaft by a trip device consisting of a tooth and pawl which is locked by the force exerted by an electric solenoid in the main motor circuit, on breaking the main circuit the solenoid is de-energized, the pawl is released and the turning cam shaft releases the cam rollers 242 thus allowing compression springs to raise the pressure roller F by sliding the pressure blocks 236 up the slideway 223. On starting the machine the auxiliary motor 161 is started first and it runs continuously, driving the intaglio roller G slowly through a clutch system. On starting the main motor its drive is over-run but still operates through the clutch system. The drive on the intaglio roller G is brought into phase with the main drive on the main-shaft 37 by means of a pawl co-operating with a single toothed ratchet on that shaft.

[Class 76.] A machine for performing boarding and like operations on hides, leather, &c. is provided with tools, having segmental operative parts, which are driven in the same direction at equal speeds, whereby the work is fed intermittently over its support and released between each feed movement, the work support being mounted vertically below the tools in a plane substantially midway between the axes of the tools. The tools 11 are mounted on shafts 4 supported between pairs of arms 3 mounted on shafts 2 about which they can be adjusted to space the tools apart. This adjustment may be effected by screws 18a actuated, through gearing, by a hand-wheel 16. The tools are rotated by means of gearing including gear wheels mounted on the shafts 2 and a beltdriven pulley 5 mounted on a shaft 5a. The tools, Fig. 5, are of different sizes for the purpose of keeping the leather in tension while being treated and each comprises a pair of side plates 14, supported by a hub 14a, and a pair of wooden kc. sections 11a carrying facings 11b of frictional material such as cork, leather, or rubber and mounted on backing plates 11c which are confined together between flanges of the plates 14. Springs or inflated tubes 15 serve to press the operative parts 11 outwardly. The outer ends of the parts 11 may be tapered towards the shaft 4, as shown in Fig. 2, in order to decrease the intensity of action on the outer and lighter parts of the hide &c. In a modified construction of tool the operative parts are supported by spiders on their shaft, adjustment of the taper being effected by the use of replaceable washers on the spider arms. The hide is supported over a tongue or bar 29 removably carried by adjustable carriers 20 which are raised, to bring the hide into position to be engaged by the tools, by a lever 28 actuated by a cam 27 which is brought into action by the operation of a clutch device 25 operable by a treadle 22. A trough 32 rotatable on a spindle is provided to receive the hides after treatment. Springs 31 carried by brackets 31b serve to keep the work frictionally in contact with the bar 29. Cleaning and trimming means for the tools consist of cutting members 38a supported by a slide rest 38 which may be moved along a guide 38b.

Filed: 1944-07-28
Abstract: 589,291. Photo-electric power meters. STANDARD TELEPHONES & CABLES, Ltd. July 28, 1944, No. 14445. Convention date, July 31, 1943. [Class 40 (iii)] [Also in Group XXXVI] High-frequency electric power is measured by passing it through an incandescent lamp together with a supplementary low-frequency power for bringing the lamp to a suitable operating point on its characteristic curve, the H.F. power being then ascertained by subtracting the L.F. power, read off from a wattmeter, from the total power supplied to the lamp which is measured photo-electrically. As shown, the lamp 8 is energized from the highfrequency source through a conventional H.F. power amplifier VI, V2 and transformer 15 and from a low-frequency A.C. source through an adjustable transformer 7, wattmeter 6 and H.F. chokes 21, 22 which prevent the H.F. current feeding back into the L.F. source. Series condensers 2, 3 similarly prevent feed back of the L.F. current into the H.F. amplifier. The lamp 8 actuates a photo-electric cell 9 in series with a microammeter 17 graduated to indicate the power output of the lamp. The H.F. power value is then derived from the reading of meter 17 by subtracting the L.F. power given by the wattmeter 6. The Specification as open to inspection under Sect. 91 also describes a relay' switch 26, Fig. 2 (Cancelled) energized by a keyer in the H.F. circuit and adapted to open the L.F. feed circuit to the lamp to avoid a chirping signal that would otherwise result from variation of the lamp load.

Title: Improvements in the solidification of carbon dioxide or other gases
IPC: C01B32/55
Filed: 1929-05-13
Abstract: 312,231. Cole, H. W., and McLaren, M. W. May 22, 1928, [Convention date]. Solidifying.-Carbon dioxide snow is formed in an expansion chamber under definite pressure and compressed to ice in a communicating chamber with a movable head. Gas is drawn in by an exhauster 11 and delivered to a compressor 15. An inverted bell gas holder 12 regulates the gas pressure e.g. by contacts on the holder controlling an electric motor driving the exhauster 11. A revolution counter on the exhauster serves as a meter. The gas is freed from oil in a separator 20 containing steel turnings &c., cooled by water in a receptacle 24 and freed from water by a mass of carbon &c. 31, unliquefied gas and air escaping by a valve 37. The liquefied gas is led directly or through an exchanger 40 to nozzles 51 by which it is expanded into a chamber 50. Here snow is formed, and is agitated and delivered to a compressor chamber 60 by blades 59 actuated by an electric motor 58. The compression chamber has a movable head 70 and a piston 61 both actuated hydraulically from chambers 66, 77 open either to the high or low pressure side of the gas circuit. The supply of liquefied gas to the snow chamber is controlled by a valve 39 which, with the contacts 96 of the circuit of the motor 58 driving the stirrers 59, is controlled by an arm 94 on the rod of the piston, through a lever 92. Gas escapes from the chamber 50 to a jacket 53 and is led to a circulating exhauster 81 having a diaphragm valve set to control the pressure conditions. In a modification, the nozzles deliver directly into a vertical compression chamber, in which a partitioned vessel rests on the movable head and forms a multiple ice block, Fig. 7, which may afterwards be broken up.

Title: Power factor control of alternators
Inventor: COBB GORDON EDWIN
IPC: H02P9/34
Filed: 1964-04-10
Abstract: 1,062,614. Automatic control of power factors. BLACKSTONE & CO. Ltd. April 10, 1964, No. 14930/64. Heading G3R. In an arrangement for controlling the power factor of an alternator having an automatic voltage regulator, a square waveform having a mark/ space ratio dependent on the power factor is compared with a reference square waveform to produce an error signal which is applied over an amplifier to the regulator which thereby operates to reduce the error to zero. As shown, voltage pulses derived from the alternator by way of a transformer 1, a diode 3 and a transistor 4, and current pulses derived over a transformer 2, a diode 19 and a transistor 10 are applied to the opposite sides of a bi-stable circuit 7, 8 which thus produces a square waveform have a mark/ space ratio dependent on the phase relationship between the voltage and current pulses. This waveform is applied over an amplifier 15, 16 to a resistor 17 which is also supplied with a reference wave-form generated by a circuit 18, 19, 20, 21; this reference signal may be derived from another alternator or a grid network, and its mark/space ratio may be adjusted by varying a resistor 22. If the power factor of the alternator differs from that set by the reference circuit an output forming an error signal is obtained from the resistor 17. This error signal is applied over an amplifier 24, 25 a power transistor 27, and a variable choke 29 to the coil 32 of an automatic voltage regulator associated with the alternator, the arrangement being such that the excitation of the alternator is varied in dependence upon the error signal whereby the power factor is maintained at the desired value.

Abstract: 623,354. Electric tests. SPERRY GYROSCOPE CO., Inc. Oct. 23, 1942, No. 14939. Convention date, Jan. 28, 1941. [Class 37] [Also in Groups XXXIX, XL (b) and XL (c)] A circuit analogous to the bridge type particularly for use at very high frequencies comprises four transmission lines 1 ... 4 connected in tandem to form a closed loop with lumped impedances Z1 ... Z4 between adjacent pairs. The transmission lines may take the form of shielded or unshielded twowire lines, coaxial lines, wave-guides or lumpedimpedance artificial lines, while one or more of the impedances Z1 ... Z4 may include a generator. If Z1 is a generator and Z3 an indicator or meter, and the four lines have similar characteristics, no current flows in Z3 when Z1 and Z3 are oppositely connected, that is to say, one in series and the other in shunt as shown in Figs. 4, 5. Such arrangements are suitable for making impedance measurements by a null method, Z2 and Z4 being unknown, and standard impedances respectively. Z2 and Z4 need not be simple shunt or series elements, as in Figs. 2, 3, but may be of more complex form, as shown, for example, in Figs. 6, 7. Fig. 8 shows a coaxial line construction in which the generator Z1 is arranged as a shunt element and the indicator Z3 as a series element. The Specification as open to inspection under Sect. 91 contains the following subject-matter: By the introduction into one of the bridge arms of a phase change of 180 degrees, e.g. by a transposition, Fig. 3 (Cancelled), or by a length of transmission line, Z1, and Z3 may be connected both in shunt or both in series thus, Fig. 13 (Cancelled), shows a hollow-pipe construction in which Z1, Z3 are both shunt elements and which includes a phase-shifting device 15 such as a line an odd number of wavelengths long. In another hollow-pipe construction, Fig. 14 (Cancelled), Z1, Z3 are series elements and the pipes 2, 3 are terminated by impedances 20, 201. This subject-matter does not appear in the Specification as accepted.
