Title: Tape applying machine
IPC: A43D44/00
Filed: 1960-01-13
Abstract: 902,252. Tape-applying machines. PRIME MANUFACTURING CO. Jan. 13, 1960 [Jan. 27, 1959], No. 1314/60. Class 73. A tape-applying machine, e.g. for applying adhesive tape along the back seams of shoe uppers, comprises a work-supporting roll 12 co-operating with a stationary horn 14 acting as a seam guide, means for feeding the tape T to the work W, rolls 20, 26 co-operating with the roll 12 for pressing the tape along the work while feeding them through the machine and tape-cutting mechanism including a knife 56 and an actuating trigger 15, the latter being so located adjacent the roll 12 and horn 14 that it is moved forward to set the tape-cutting mechanism when the work W is presented to the machine and is automatically released to cause movement of the knife 56 to sever the tape after a predetermined advance of the work W. The trigger 15 is pivoted at 16 and in the operative forward position shown, engages the operating button B of a microswitch 17, causing a solenoid 35 to be de-energized and permitting upward movement of a plunger 34. The plunger 34 is connected by a link 33 with an arm of a pivoted spider 32 which is thus moved clockwise about the pivot 30 by the action of a spring 31. This causes a forked guide or hold-down 50 to move downwardly from a raised position, Fig. 2 (not shown), to a position adjacent the roll 12. The knife 56 projects from a cam 47 pivoted at 21, the cam 47 having a slot 49 engaged by a cam follower on a downwardlyextending arm 48 of the spider 32. Thus clockwise movement of the spider 32 causes anticlockwise movement of the cam 47 and the knife 56 is moved upwardly and rearwardly into the position shown. When the trailing edge of the work W releases the trigger 15, the solenoid 35 is energized, the spider 32 moves anti-clockwise, the cam 47 moves clockwise and the knife 56 is swung into the path of the tape T to sever it while the guide 50 rises to its inoperative position. The tape T is led to the machine between guide rolls located in the upper end of an arm 62 and then passes through a wire guide 63, between guide rolls 64 and downwardly through a flat tape guide 39. The machine includes automatic means for advancing the tape to the bite of the feed roll 26 when the trigger 15 is tripped and the hold down presser 50 brought into its operative position.

Title: Improvements in or relating to combing machines for textile fibres
IPC: D01G19/14
Filed: 1937-01-16
Abstract: 489,003. Combing-machines. NASMITH, J. W. Jan. 16, 1937, No. 1337. [Class 120 (i)] In a combing-machine for textile fibres having upper and lower detaching rollers d<1>, D, Figs. 1, 2 and 4, operating as set forth in Specification 16001/01, [Class 120], the lower detaching roller D is bodily withdrawn from the combing cylinder Y on completion of detaching to back-off the end of a fleece for piecing, and the upper detaching roller d<1> falls behind the withdrawn lower roller D, the combined movement being such that the backed-off fleece end is directed away from the cylinder on return of the rollers to their normal positions. The lower roller D and the transporting rollers C, C<1> are carried in a bearing 1 secured to legs 3 pivoted at 4, the bearing 1 being reciprocated by a cam acting through a shaft 10 connected to each leg 3 by a rod 7 and a lever 9. The upper roller d<1> is mounted in bearings carried by a lever 18 pivoted at 17 in an arm 15 adjustably secured to a lever 14 keyed upon a shaft 11. The lever 18 is locked by a bolt B to a bracket 19 hinged on the stud 17, the bracket 19 being formed with a boss 20 on which is pivoted a forked spring lever 21 having a projection 22 which passes over the squared end of the bolt B and keeps it in position when working. The forked end of the spring lever 21 embraces the block 23 through which passes the end of the rod 24 carrying the spring 25 and pivoted at 27 to a lever 28 itself pivoted on a pin 29. A latch 30 pivoted on the pin 13 engages over the pin 27, and a lever 31 also pivoted at 13 supports on a stud 32 the lower end of the rod 33 carrying the spring 34. A link 35 connecting the pins 27, 32 serves to release both springs 25 and 34 when removal of the lever 18 and roller d<1> is necessary. In operation, during detaching the roller D remains in the position of Figs. 1 and 4 whilst roller d<1> rolls round D away from the advancing nipper N. The nipper N withdraws and the separation is made leaving the rear end of the detached fleece at T, Fig. 1. The bearing 1 and roller D are then withdrawn to the position of Fig. 2 and the roller d<1>, controlled by the lever 18, falls behind the roller D and the rear end of the detached fleece is at T<2>. Just before the roller D reaches its outward position its direction of rotation is reversed in the direction of the arrow, Fig. 2, and during the short dwell in its extreme position the backing-off of the end of fleece is completed to the position T<3> well away from the cylinder cover 38. The rollers then resume the position shown in Fig. 4, and the operation recommences. During the movements of the roller d<1>, the pressure thereon is controlled by the springs 25, 34 so that as the roller is passing from the position of Fig. 4 to that of Fig. 1 and back again, the spring 25 is compressed. When the roller begins to fall to the position of Fig. 2, the spring 25 is inoperative and only the lighter pressure of the spring 34 is exerted.

Abstract: 1495023 Tabulation device for printers SIEMENS AG 14 Jan 1975 [25 Jan 1974] 1464/75 Heading G4H A tabulator device TE for typewriters, teleprinters and data printers comprises a store SP having electronically-operable storage elements for the storage of tabulation markers, the store being addressed by registers R1 and R2. TE also comprises write-in and read-out control units SB, LE. As shown, TE forms part of a teleprinter (Fig. 1, not shown) containing, inter alia, a keyboard (TA), a printer (DR), a tape punch (LS) and transmitter and receiver control units SST, EST. Store SP is a 5 x 16 matrix of MNOS metal nitride oxide substrate) transistors which retain stored data even after the disconnection of the operating voltage (Fig. 2, not shown). SP is addressed by row and column registers R1 R2 (containing circulating 1 bits) via gates U1, &c. and U2 &c. enabled by pulses IM from a monostable M. The tab bits are extracted by depression of a tab key TS which sets a flipflop F1 and causes SST to emit "interspace" or "line feed" signals (for horizontal and vertical tabulation respectively) to the printer, for moving the print carriage in synchronism with the circulation of R1, R2, and to EST which feeds signals to R2 (connected by an "overflow" pulse ST to R1) and M. When a tab-bit TM is read-out it resets F1 and stops SST and the print carriage until TS is pressed again. Tab bits are entered into and erased from SP by means of keys SE, LO. Each element in SP is addressed via transistors TL (one per row) and TS (two per row) connected to a source SU of voltages -US (for write-in) and +US (for erase) and to gates U4, U5 respectively. The print carriage is again shifted in synchronism with the circulation of registers R1, R2.

Title: Steam generating unit
IPC: F22G5/04
Filed: 1963-01-14
Abstract: 974,398. Water-tube steam boilers; regulating steam temperature. RILEY STOKER CORPORATION. Jan. 14, 1963 [Jan. 15, 1962], No. 1552/63. Heading F4A. In a steam boiler having an upright combustion chamber fired by burners mounted at the lower portions of the front and rear walls, the upper region of the chamber is divided into three gas passes by vertical baffles parallel to these walls, a reheater being disposed in the first and middle pass whilst a superheater is disposed in the middle and third passes, the reheat and superheat temperatures being maintained at a preset value over a wide range of loads by positioning the main stream of hot gases in relation to the inlets to the passes by means associated with the burners. In the form shown, the boiler has a vertical combustion chamber 18 lined with steam generating tubes extending between lower headers 27, 29 and a steam and water drum 25. On the front and rear walls 15, 16 of the chamber the tubes are bent inwardly to form abutments 21, 23 on the undersides of which are located burners 22, 24. The burners fire into a high temperature cell 50 and are respectively provided with adjustable vanes 76, 78 and 82, 84, the setting of which controls the position of the main stream of hot gases between the front and rear walls of the chamber 18. At the top of this chamber baffles 34, 35 divide the gas flow path into three passes 114... 116, a superheater 62 being located in the rear and middle passes 115, 116 and whilst a reheater 72 is located in the front and middle passes 114, 116. Radiant reheater and superheater platens 67, 57 are disposed in the chamber 18 below the passes 114, 115 respectively. The gases leaving the passes 114 ... 116 combine in an open space 119 and flow laterally through an offtake opening 118 and then downwardly in two passes 38, 39 respectively containing an economizer 123 and a primary reheater 71, the gases being proportioned between the passes 38, 39 by dampers 42, 43. The gases then recombine for flow through an air heater 44 to the stack 45. Steam from the drum 25 passes successively through tubes lining the back passes, the radiant superheater 57, a desuperheater 59 and the convection superheater 62 to an outlet header 63. Steam for reheating enters a header 65 and flows serially through the reheaters 67, 71, 72 to an outlet header 70. Temperature pick-offs 103, 105 respectively disposed in the headers 63, 70 transmit signals representative of superheat and reheat temperature to a controller 91 which causes the burner vanes 78, 84 to be adjusted to position the hot gas stream between the superheat and reheat sides of the chamber 18. Thus, at high load when heat transfer for reheating must be high, the stream is positioned against the wall 15. As the load is reduced the controller moves the stream across the chamber until at low load it is positioned against the wall 16. Temperature correcting adjustments are simultaneously made to the gas proportioning dampers 42, 43, the water injection rate to the desuperheater 59 and the air supply to the burners.

Abstract: 1421831 Piezo-electric transducers TED BILDPLATTEN AG AEG-TELEFUNKEN TELDEC 12 Jan 1973 [22 Jan 1972] 1688/73 Heading H4J High frequency (e.g. video) signals are mechanically recorded by a piezo-electric longitudinal vibrator 1 composed of an amorphous mixture of metal oxides, particularly Pb, Zr and Ti, and having a longitudinal coupling coefficient of at least 0À6 which, in conjunction with the resistance of the feed current circuit, causes the quality factor Q, which is a measure of the mechanical amplitude of the arrangement as a function of frequency at the inherent resonance frequency of the vibrator, not to exceed 10 dB. The arrangement records up to 400 kHz. The piezo-electric mixture is selected so that the vibrator body has an inherent quality factor of 50 and its dimensions are such that the inherent resonance frequency lies above the frequency range to be recorded. A heated cutter 2 is fitted to a heat conductive tube 3 welded to a plate 4 soldered to the body 1, and the assembly resiliently supported on T-shaped springs which provide the electrical power input conductors and which resonate below the frequency range to be recorded. The longitudinal vibrations are damped by an elastomeric ring 9. The resistance of the feed circuit is 50 K # and provides a substantially fixed current of 30-50 mA at 1À5 kV. The self-capacitance (150 pf) of the vibrator increases the power output at low frequencies. The oxide mixture is ground, wet-compounded, filtered, dried and heated to 850‹ C. before wet-grinding to a desired grain-size permitting the formation of a solid body by binding and pressing in a die. The body is sintered at 1100‹ C., ground or cut to the desired shape and polarized at 140-300‹ C. in a field of 1 to 5, typically 3 kV/mm.

A semi-conductor controlled, rectifier consists of two PNPN, PNPM or NPNM devices with three zones in common. The distances from the closely spaced non-common junctions to the adjacent common junction differ so that the devices have different breakdown voltages. In consequence the device with higher breakdown voltage can be made to breakdown below its normal breakdown voltage by applying a breakdown voltage to the other device. The typical device shown in Fig. 2 is made by diffusing gallium into an N-type silicon wafer to form a P region which is then divided by annular groove 18. The emitter ring 22 and gate dot 24 are made of antimony doped gold and ohmic contact 20 of boron doped gold. These are all alloyed to the body by heating for 10 minutes at 700‹ C. Germanium, silicon carbide and A III B V  and A II B vI  compounds may alternatively be used as semi-conductors.
