Title: Apparatus and method of compressing travelling material longitudinally and products thereof
IPC: D06C21/00
Filed: 1962-03-09
Abstract: 997,879. Compacting and craping fabrics and paper. R. R. WALTON. March 9, 1962 [March 22, 1961], No. 9244/62. Headings D1S, D2A and D2B. A machine, Fig. 8, for compressing materials 1 longitudinally comprises a moving feed surface 14, for example a roller, a retarding member 16 stationary with respect to the direction of movement of the material 1, and a containing surface 34 extending over the feeding surface 14 and the retarding member 16 to form a short passage therewith, characterized in that in said passage the containing surface 34 continuously diverges from the moving surface 14 to a maximum spacing adjacent to the retarding member edge and then converges towards the retarding member surface to a restricted outlet therebetween. This arrangement causes the material approaching the leading edge of the retarding member 16 to disengage from the surface 14 preceding said leading edge and to press against said containing surface 34 at the maximum divergency of the passage so avoiding any possibility of the material catching on the leading edge of the retarding member 16 and avoiding the necessity of the retarding member 16 being made to contact the feed surface 14 to act as a scraper. The restricted outlet causes the material to be compressed, compacted or creped as it approaches and leaves said maximum spacing in said passage. The bores 77 in the shoe 20a are for heating and cooling means. The containing surface 34 may project beyond the edge of.a shoe 20a and may be resilient. Such a projection may also be in the form of a plurality of adjacent or spaced apart fingers, Fig. 9 (not shown). In Fig. 9 antifriction fluid can be fixed down the passages 98. The roller 14 may have an abrasive or indented surface, for example a ribbed and grooved periphery 15, Fig. 1 (not shown), the ribs extending at an angle to the axis of the roll. The products that can be compacted and creped by the machine are non-woven textiles and soft synthetic films having such fine crepes as to resemble woven materials and being permanently stretchy; papers minutely creped with undulations pressed tightly together, paper tissue compressed lengthwise to one quarter of its original length, rendered stretchy to resist tear and rendered absorbent; resilient materials such as double thickness, knitted cotton textile evenly shrinkproofed on both sides; metal foils minutely crimped, loosely woven materials compressed into a tight fabric.

Title: Improvements in or relating to remote indicating compasses
IPC: G01C19/36
Filed: 1945-04-13
Abstract: 591,019. Magnetic tests and measurements. HUDSON, C. S. April 13, 1945, No. 9328. [Class 37] In a remote indicating compass for aircraft, ships, &c., the two components of the earth's magnetic field are obtained irrespective of the position in space of the magnetic elements of the compass. As shown, four sine-cosine potentiometers 1, 2, 3, 4 are employed with centre-tappings and brush connections and electromagnetic pick-ups adapted to be rigidly attached to the craft, are used to produce currents proportional to the three components of the earth's field along the vertical, pitch and roll axes of the craft. These currents are fed respectively to potentiometers 1, 2, 4 and by means of a vertical gyroscope the potentiometer brushes 11, 12, 13, 14 are operated in accordance with the angle of roll of the craft and brushes 15, 16 in accordance with the angle of pitch. The resultant currents proportional to the two required horizontal components are transmitted to amplifiers 22, 23 so as to produce signals in the coils 18, 21, positioned as shown, to give a compass heading on the indicator 19 corresponding to the vector sum of the two currents. In an alternative arrangement (Fig. 2, not shown), three induction regulators are used with their input field windings connected to the pick-ups and their rotors operated by the gyroscope in accordance with the angle of pitch and roll so as to induce currents in the rotor windings proportional to the two required horizontal components.

Title: Dc-to-dc converter
IPC: H02M3/338
Filed: 1973-02-27
Abstract: 1416500 Inverter oscillators INTERNATIONAL BUSINESS MACHINES CORP 27 Feb 1973 [31 March 1972 (2)] 9632/73 Heading H3T [Also in Divisions G3 and H2] A D.C.-D.C. converter comprises a push-pull oscillator formed by transistors Q5, Q6 and transformer S1, the transistors having their common emitter current controlled by a further transistor Q20 in dependence on the voltage across at least one half of the primary winding of the transformer S1. As described, the collector voltage of Q5, Q6 is rectified by diodes CR3, CR4 and used to charge a capacitor C4 the voltage of which is reduced by potentiometer P1 and compared in a differential amplifier Q13, Q14 with a reference voltage at the junction of two Zener diodes CR1, CR2. The error voltage at the collector Q14 is passed by transistors Q1 and Q11 to the base of Q20 where it controls the emitter current of the oscillating transistors Q5, Q6. The output is stepped up by secondary winding S2 and rectified by a voltage multiplier MULT to provide the required D.C. output. Starting.-When the D.C. supply VIN is first connected, transistor Q15 is turned on by the charging current of C10. This allows Zener diode CR10 to conduct in the forward direction, clamping the base of Q16. As C10 charges, the collector voltage of Q15 rises until Zener diode CR10 exhibits reverse breakdown, turning on Q16 which turns on Q9 so as to provide a small starting current for the oscillator transistors Q5, Q6. The output voltage is rectified by diodes CR3, CR4 so that Q1 is turned on which turns on Q11 and hence the emitter current source transistor Q20. Overcurrent protection.-The common emitter current of the oscillator transistors Q5, Q6 is monitored by R27 and charges C15 which supplies emitter current to Q2. The base of Q2 is supplied with the rectified voltage from CR3, CR4 via transistor Q4 and a potential divider R30, R21. When the oscillator current is sufficiently high to turn on Q2, Q17 is also turned on so as to discharge C10 through diode M3 and temporarily shutting off the start circuit.

Filed: 1970-02-27
Abstract: 1301193 Bilateral controlled rectifiers MULLARD Ltd 27 Feb 1970 9723/70 Heading H1K In a bilateral controlled rectifier consisting of a PNP (NPN) sandwich structure with further N(P) zones formed in its outer zones and shorted thereto by the main current electrodes, the gate electrode is located adjacent the only region in which the projections of the two further zones overlap. This provides the optimum commutation speed consistent with sensitive turn-on of the device. A typical construction prior to double bevelling is shown in Figs. 16-18. In this the further zones 34, 35 overlap an amount d 1  (À25 mm.) adjacent the circular central gate electrode 29 but the projections of their adjacent peripheries are elsewhere parallel and spaced apart by twice this amount sub-zone 34a being removed during bevelling. Both zones can be apertured, as shown, to allow the adjacent outer zones to surface locally beneath electrodes 37, 28 respectively. Annular electrode 37 is spaced a distance d 3  from the region of overlap. In this embodiment an N type gate region is provided and has a re-entrant portion in which the gate electrode 29 also contacts the adjacent outer zone. This construction enables the device to be triggered by pulses of either polarity irrespective of the direction of conduction but where this is not required the gate electrode may be disposed entirely on the gate region or directly on the outer zone. Typically the device is formed from an N type silicon disc, which after diffusion of gallium and/or boron to a depth of 50 Á to form the outer zones is ultrasonically cut into smaller discs. These are conventionally oxide masked, diffused with phosphorus to a depth of 20 Á to form the further and gate zones, remasked, and provided with gold-plated nickel electrodes by electroless deposition. After a two-stage bevelling process electrode 28 is soldered by a lead/tin or gold-germanium disc to a header and leads attached.
