Patent GB-882980-A (GB)
Title: Improvements in or relating to pulse converting circuit arrangements employing transistors
IPC: H03K5/156
Filed: 1958-01-30
Abstract: 882,980. Circuits of bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 30, 1958 [Feb. 1, 1957], No. 3143/58. Class 40 (9). [Also in Group XL (c)] In a circuit for converting input pulses Vi, Figs. 1 and 2, into a corresponding or complementary sequence of output pulses Vo of constant width and amplitude, the input pulses are fed over an isolating diode 7 to the baseemitter path of a transistor 8 having clock pulses Vt applied to the collector circuit which occur after the termination of the input pulses to generate the desired output pulses. The transistor has a current amplification factor, the cut-off angular frequency of which is smaller than the reciprocal value of the width of the clock pulses and the diode has the same pass direction as the emitter-base of the transistor. The circuit is described as applied to a system for reading out information from a magnetic core 1 to which a pulse V u  is applied over winding 2. The output from the core is fed to the primary of a transformer 5 across the secondary of which is developed the pulse Vi. If the pulse Vu reverses the state of magnetic saturation of the core 1 the generator of the pulse Vu is coupled tightly to the transformer 5 and a large pulse Vi results. In contrast, if the magnetic state is not changed only minor pulses result. Due to the bias arrangements 9, 10, 11 the emitter-base and diode 7 are reversally biased so the small pulses are suppressed, but the large pulses pass through the diode 7 to cause base current Ib and effect charge storage in the base region of transistor 8. The succeeding clock pulse Vt is effective to cause current flow Ic which gives substantially no output Vo for a large input pulse Vi and vice versa. The resistor 12 is chosen of such a value that residual charge leaks away between successive clock pulses. In a modification, Fig. 3, operating as an AND circuit two cores 1, 1<SP>1</SP> are arranged with a single winding 2 and two windings 3, 3<SP>1</SP> in series to feed the transformer 5. Capacitors 19, 20 may be added to suppress the small pulses which occur when the cores are driven further into their saturated condition. The diode 7 is reversally biased by the arrangements 9, 10, 11 to suppress further the small pulses and the resistor 12 is returned to earth with a capacitor 18 to enhance the memory effect. By employing the clock pulse source 15 connected to a transformer 22 in the collector circuit of transistor 8, output pulses V<SP>1</SP>0 are generated across the load resistor 13 and are complementary to the pulses Vo. The transistor 8 may be operated in the common base circuit, Fig. 4 (not shown). Specifications 827,666 and 835,907 are referred to.

Title: Improvements in fans
IPC: F04D17/16
Filed: 1958-01-30
Abstract: 849,744. Helico-centrifugal fans. BLACKMAN Ltd., K., and HUMPHREY, D. Jan. 30, 1959 [Jan. 30, 1958], No. 3148/58. Class 110 (1). The air inlet 11 of a fan is of Venturi form, the impeller being located in the widening part of the Venturi beyond the throat. The impeller blades 14, mounted on a conical hub 13 and surrounded by a conical shroud 15, are of compound curvature such that they impart to the air first an axial and then a centrifugal component of flow. The air is discharged in the axial direction by guide vanes 22 which are flanged for attachment to the cylindrical casing 10 of the fan and to the housing 23 of the driving motor. Diffusion is provided in the annular space between the casing 10 and a fairing 24. The housing 23 may be merely a support for a separate shaft and bearing assembly for the impeller.

Title: Bag-making machine
IPC: B31B50/00
Filed: 1966-01-25
Abstract: 1,133,458. Feeding sheets. WINDMOLLER & HOLSCHER. 25 Jan., 1966 [16 Feb., 1965], No. 3320/66, Heading B6B. [Also in Division B5] Tube sections 1 . . . 5, (Fig. 1), to be made into bags are discarded by a movable deflector or deflectors if their widths are outside a tolerated range checked by photo-electric devices C, D. In the form illustrated the tube sections are pushed by an endless conveyer in the direction of the arrow 6 against stops 7, 8, on a slower moving conveyer. Timing cams driven in synchronism with the conveyer connect the photoelectric devices C, D to a circuit including thyratrons and magnetic relays so that tube sections which are too narrow to cover the photoelectric device C, or so wide as still to cover the photo-electric device D, when the leading edge 10 is in apredetermined position, are discarded. Further photo-electric devices A, B detect tube sections which are not properly aligned with the stops 7, 8, and a further photoelectric device E prevents operation of the deflectors when a tube section is missing entirely. A single deflector may discard all the wrongly sized sections, or the undersized and oversized sections may be deflected to separate discards. Preferably the solenoids controlling the deflectors merely unlock them, the movement being provided by a drive from the bag-making machine. The solenoid operating the deflector may be an A.C. solenoid operated from a D.C. supply with a reservoir condenser providing an initial high current to operate the solenoid rapidly as in Specification 1,109,732.

[Also in Group XVIII] Cars are handled at a pit head 1 by traversers which move around an endless track 2, 4, 3, 5. The traversers are moved continuously on the parts 2, 3 by creepers 8, 9, and on the parts 4, 5, where they may be halted as required, by powered rollers 10. Each traverser can accommodate a single deck-load of cars, which are moved on to the traversers from tracks 11 and off on to tracks 19 or 20. Empty cars are moved on to traversers from tipplers 24, 26 and returned to tracks 16. All the car movements are controlled from a bridge 32. Tracks 21, 22 are storage tracks provided with propelling means, which may be reversible, for the oars, and tracks 50 provide access to the system. The traverser tracks 4, 5 may pass close to the shaft 1 enabling cars to be transferred direct between the cage and the traverser. Each traverser runs on wheels 34, Fig. 2, and is driven either by a continuously-moving chain 39 with projections 41 which engage a member 40 on the traverser, or by powered rollers 46, 47 engaging rails 48, 49 on the traverser. Rollers 37 guide the traverser on the bends, and ramps engaging a roller 43 may be used to lift the member 40 clear of the chain. The chain track 42 may run below the spindles 45 on the parts where powered rollers are provided. Plate-type conveyers may be used in place of the powered rollers. The traversers may alternatively be powered by electric motors mounted on them and controlled by switches operated by movable ramps on the track or by radio. They may be connected in groups, and only one traverser of a group need then be powered. Each traverser may carry a decking ram of known type.

Title: Improvements in and relating to the metallisation of solid non-porous non-conductivematerials
IPC: C25D5/54
Filed: 1944-02-29
Abstract: 575,148. Metallizing non-conductive materials. CALLENDER - SUCHY DEVELOPMENTS, Ltd., and SUCHY, C. T. Feb. 29, 1944, No. 3713. [Class 41] In the metallizing of glass and other non- porous, solid, non-conductive materials, good adhesion of the deposit to the glass is effected by first rendering the surface thereof porous or rough, and introducing electrically-conductive material into the pores or recesses, whereupon the surface is freed from conductive particles to render it non-conductive, while leaving conductive particles in the pores or recesses, electro-deposited metal then being applied. The invention thus uses the process of Specification 572,071. The pre-treatment may be abrasion by means of pumice or carborundum powder, scoring, engine turning, mechanical pitting or chemical etching, and may be preceded by brush-cleaning and degreasing and cleaning with caustic soda or trichlorethylene. After the roughening, the material must be dried and freed from loose particles, whereupon the treatment set out in Specification 572,071 is applied to produce an electrolytic coating of copper followed, if required, by one of a noble metal. In treating glass, the surface is first cleaned, then treated with frosting powder, degreased and cleaned with caustic soda, and washed. The plating current was initially ¢ amp./dm<2> at 1¢-3 volts, these figures being later increased to 1 amp. at 4-6 volts. The temperature may be 18-20C. but could be increased to speed up the process.

Title: Improvements in and relating to coarse and fine adjustment devices for wireless apparatus and for other apparatus, and to indicating dials or the like therefor
IPC: H03J1/14
Filed: 1927-02-10
Abstract: 278,238. Camp, H. J., and Watson, C. Feb. 10, 1927. Wireless tuning-apparatus, adjustment devices for.-A coarse and fine adjustment device for wireless and other apparatus comprises two internally toothed rings 9, 17, the numbers of teeth on which differ by one or more, which are engaged by an eccentric externally-toothed ring 32 of smaller diameter. The upper toothed ring 9 is integral with the graduated flange 10 which has two diametrically-opposite upwardly-extending portions (not shown) which form finger grips and are joined at their upper ends by a bridge 12. These parts may be formed from a moulding of insulating material in which is fixed a screwed metal liner 13 into which is screwed a spindle 14 which is bored at 22 to receive the end of the spindle to be adjusted. The lower toothed ring 17 may be moulded from insulating material with a metal bush 18 which works freely on a reduced portion of the spindle 14. Attached to the liner 18 or the ring 17 is a spring plate formed with three arms carrying compressed cork, leather, or like pads 21 which bear against the surface of the panel 34. Fine adjustment is effected by a knob 16 moulded from insulating material with a downwardly extending conical web 24 ribbed externally to provide a finger grip. The knob is provided with a metal liner working freely on the spindle 14, and is formed internally with three projections 25, 30. Two of these carry downwardly projecting pins or studs which engage the internal circumference of the externally toothed ring 32. The third projection 25 carries a spring 27 which engages the internal circumference of the ring 32 and presses its teeth into engagement with the teeth of the rings 9, 17. The spring 27 and the pins carried by the projections 30 form a skeleton eccentric sheave for the ring 32 and on rotation of the knob 16 cause this ring to roll in contact with the rings 9, 17. In an example the lower ring 17 has 114 teeth and the upper ring 9 has 115 teeth. A complete rotation of the knob 16 therefore causes a relative rotation of 1/115 of a revolution between the rings 9, 17. The lower ring 17 being prevented from rotation by the friction of the pads 21 on the panel, the flange 10 is moved by this amount in the same direction as the rotation of the knob. Coarse adjustment is effected by rotating the mechanism as a whole by means of the finger grips integral with the bridge 12. the pads 21 sliding on the panel. The ring 32 may be formed with two equal or unequal sets of teeth, one meshing with each ring 9, 17. The ring 32 may be mounted on an eccentric sheave with or without spring means for compensating for irregularities.

Title: Improvements in bottle vending machines
IPC: G07F11/10
Filed: 1954-02-09
Abstract: 740,098. Vending apparatus. JOHNSON, F. F. Feb. 9, 1954, No. 3840/54. Classes 27 and 116 In a bottle-vending machine in which bottles stored in a vertical refrigerated magazine 10 are fed singly by gravity past a star-wheel gate 16 to a discharge shoot 12, the number of teeth on the ratchet wheel 19 of the escapement mechanism or the star-wheel is a multiple of the number of teeth on the star-wheel and the escapement pawl 20 is actuated a number of times corresponding to this multiple to permit the starwheel to rotate sufficiently to release a bottle. The end 20c of the centrally-pivoted pawl 20 is shaped so that. if the ratchet wheel 19 fails to rotate owing to jamming or other reason, the end 20c will engage the upper end of the adjacent ratchet tooth and prevent full rocking movement of the pawl. A spring-loaded pawl 32 prevents forced reverse rotation of the star-wheel. In order to rock the pawl 20, a coin-released operating handle is adjustably connected to a shaft 24 and a cam plate 22 on the shaft has a sinuous groove 23 engaging a roller 20a on the pawl. The groove has three undulations so that, when the shaft 24 is rotated in one direction and then allowed to return under the action of spring 30, the pawl is actuated six times, allowing a 90 degree rotation of the four-toothed star-wheel. A reversible pawl 28 prevents reverse movement of the cam plate when it is moving in either direction. Alternatively, the pawl may be solenoid controlled. The rack 1 in the magazine feeds directly into the shoot 11 leading to the discharge shoot and the bottles in the other racks 2-5 are supported by spring-loaded gates 42-45 which initially are all in the raised position .shown for the gates 42 and 45 in Fig. 4. As the bottles in rack 1 are delivered and the last bottle clears a finger 64 on a shaft 60, the finger moves into the rack and allows a latch 56 to disengage, thus releasing a spring-loaded lever 52 on the shaft 46 for the gate 42 so that the gate can fall under the weight of the bottles. The release from rack 2 continues until a finger 65 is released to move into rack 1 and a latch member 57 is disengaged from a lever 53 to release the gate 43 of rack 3. The release from racks 4 and 5 continues similarly after freeing of fingers 66 and 67. Freely-pivoted gates 72-75 facilitate the movement of the bottles.

Abstract: 416,480. Lubricating axle-bearings. MATTHEWS, E. F., Elm Cottage, Watford Road, Wembley, Middlesex. Feb. 8, 1933, No. 3847. [Class 12 (iii).] An axle bearing is lubricated by lubricant which is elevated by the rotation of the axle-journal being supplied as a jet by means which act dynamically, the jet passing on to the axle-journal across the wedgeshaped space existing between the axle-journal and the fixed bearing brass. As shown, a cup shaped member 14 has vanes 13, is journalled on a pin 15 on the cover 16 of an axlebox 3, and is rotated by a pin 17 on the axle 1. The pin 17 engages a slot 18 in the member 14. Recesses 24, 21, in the axle box 3 and brass 2, respectively, lead to a passage 11 which opens out into the wedge-shaped space 12 between the axle-journal 1 and the brass 2. Upon rotation of the axle-journal the lubricant raised by the member 14 passes through a recesses 24, 21, and passage 11 and issues as a jet upon the axle journal. The walls of the recesses 24, 21 are so shaped that the lubricant receives an impulse as it enters the passage 11. The member 14 is mounted a little below the axis of the axlejournal. More than one passage 11 may be provided.

Abstract: 841,970. Controlling fuel supply to furnaces. ELECTROFLO METERS CO. Ltd. Feb. 6, 1959 [Feb. 6, 1958], No. 3995/58. Class 51 (1). In a furnace having a number of air supply units and a number of fuel supply units, in the event of failure of one air supply unit, the fuel supply is automatically regulated in proportion to the available air supply. Fans 1 supplying air to a boiler plant are controlled in accordance with the load by a transmitter 7 responsive to the rate of steam flow in the main 8 and regulator 6. Each mill supplying pulverulent coal to the boiler and swept by primary air from a main 16 is controlled by a regulator 14 through servo-mechanism 18 adjusting a variable speed drive for the coal feeder. The regulator 14 adjusts the drive in accordance with a load demand signal from transmitter 7 modulated by a regulator 11 responsive to the pressure in the main 8, by a signal from 17 dependent on the difference in air pressure across the mill, and a signal dependent on the rate of air flow through the mill from the main 16. The rate of air flow through the main 16 to the mills is controlled by a servo-operated valve 19 and regulator 15. Summators 9, 13 supply signals dependent on the total air and fuel supply respectively to a regulator 12 which passes a signal to a relay 23. The relay 23 is so connected to the motors driving the air supply fans 1 that, if a motor fails, the control signal dependent on the load applied to the regulators 14, 15 from the transmitter 7 is replaced by the signal from the regulator 12 dependent on the total air supply available. The control apparatus may be electronic or pneumatic. In the case of pulverizers supplying fuel at a rate dependent on the primary air flow rather than the rate of supply of raw fuel, signals from the air flow regulators 15 are used to represent the total fuel supply.
