Title: Method and devices for determining the condition of a rail track
Inventor: PLASSER FRANZ
IPC: G01M99/00
Filed: 1969-04-25
Abstract: 1,272,627. Indicating condition of railway track. F. PLASSER. 25 April, 1969 [25 June, 1968], No. 21168/69. Heading B7N. [Also in Division G1] The condition of a length of rail track is ascertained by measuring or calculating the changes in radial acceleration in the vertical and horizontal planes of a vehicle travelling at a constant speed over the track, combining these values vectorially and comparing this value with a predetermined value representing a satisfactory track. In one embodiment (Fig. 6) two vehicles spaced by a fixed length have their axles terminating at E1, E2 in facing plates 6, 6<SP>1</SP> separated by insulating material 10. Each plate carries a coil assembly 7, 7<SP>1</SP>. When one coil is A.C.-energized the voltage induced in the other is indicative of the relative vertical (or horizontal) displacement from which the curvature of the track and the radial accelerations at a standard vehicle speed are calculated. The plates 6, 6<SP>1</SP> may alternatively form a variable capacitor. The relative displacement between the ends of the vehicles may be measured mechanically, using a rope 15 (Fig. 8) attached to the end E4 of one vehicle and to the end E5 of the other vehicle by a spring 19, the rope is guided over pulleys 16, 17, 18 and attached to the pen 20 of a recorder 22.

Title: Improvements in and relating to double throw automatic electric circuit breakers
IPC: H01H77/04
Filed: 1944-11-01
Abstract: 620,027. Protective cut-out systems; electrically-tripped switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 1, 1944, No. 21362. Convention date, Nov. 1, 1943. [Classes 38(iii) and 38(v)] A double-throw circuit-breaker or switch comprises resilient switch members 17, 18 displacable by the camming engagement of a manually-operable lever 12a, selectively to bridge contacts 13, 14 or 15, 16, at least one of the members 17, 18 being of arcuate section and thermally deformable, e.g. bimetallic. to separate the associated comtacts on excess current. The lever 12a, pivoted at 26, is biased to the neutral position, Fig. 1, by co-axial torsion spring 30, secured at its ends to arms 31, 32, which are loosely mounted on the spindle 26 and abut against fixed stops so that movement of either arm by a lug 33 on the lever 12a stresses the spring 30. When the lever 12a is moved counter-clockwise against the spring 30, the tip 27 moves the member 18 against a weak spring 22 until the contacts 16, 18a and 15, 18b close and the tip 27 rests in an indentation 29, the member 18 being stressed by its pressure on the fixed contacts, Fig. 3 (not shown). The member 18, when overheated by the current it carries and by a series connected heater 41, springs from its normal curvature to an opposing curvature, thus separating the contacts and allowing the, lever 12a to return to its neutral position. Until the member 18 has cooled and snapped back to its normal curvature, its displacement by the lever 12a is not sufficient to close the switch. Clockwise movement of the lever 12a bridges contacts 13, 14 by means of the member 17, which has no heater. By connecting the contacts in parallel the switch can be used for starting and then running an induction motor 46, Fig. 6, the " starting " member 17 having no indentation 28 and both members 17, 18 having heaters 41, which are energized only during starting. In a further modification, Fig. 5 (not shown), the member 17 operates at a much higher current than the member 18, and a heater is connected in series with the latter as in Fig. 1.

Title: Apparatus and method for skin packaging articles
IPC: B65B11/52
Filed: 1964-05-25
Abstract: 1,037,462. Skin packaging. P. D. J. DICKS and W. M. HILL. May 25, 1964 [June 7, 1963], No. 21491/64. Heading B8C. In a method for skin packaging an article 28 to a base sheet 22 of paper board or the like, a lower clamping plate 20 and clamping ring 14 are moved upwardly so that a sheet of transparent plastics material 24 is trapped between the clamping ring 14 and an upper clamping plate 10, and then an upper clamping ring 18 is moved downwardly so as to press the sheet 24 against the edges of the board 22 (Fig. 4, not shown). The lower edge of the ring 18 is provided with channels 39 so that air may be evacuated from inside the package via these channels and via vacuum chamber 38 and 40 (Fig. 3, not shown). The peripheral edge of the base board 22 may be coated with heat sensitive adhesive, which is activated by heat supplied to the clamping plate 10 by heaters 36. After the transparent sheet 24 has been sealed to the base sheet 22, the clamping plate 20 and the clamping ring 18 are raised so that blades 52 cut the sheet 24 around the periphery of the package. The sheet 24 may be softened by the heat from the clamping plate 10 so that it will stretch as it is drawn over the article 28 by the clamping ring 18, and thus give a tight cover. The lower surface of the base board 22 may be coated with wax to make it less porous. Conveyers.-The sheet material 24 is fed from a roll 23 (Fig. 1, not shown) by a spiked conveyer 27.

In Fig. 1, ore is fed to a multiple hearth furnace 2 where it is pre-reduced as it is passed downwardly by rakes 28, 29 until it reaches a rotary perforated distributer 7 spreading it evenly over reduction layer 6. Oil from container 10 is injected through tubes 13 into layer 6 which is heated by consumable electrodes 3. Liquid or gaseous cooling agents are fed from container 15 via nozzles 17 and solid cooling agent is introduced from container 38. Air is injected through circular conduit 19 preheated by waste gases in heat exchanger 20. Thermocouples 45 measure the temperature of gases leaving the melting furnace, and automatically adjust the amount of coolant injected. In a modification (Fig. 2, not shown) the pre-reduction furnace takes the form of a rotary kiln, and water-cooled electrodes are used in the melting furnace. Fluidized bed and cyclone furnaces may also be used for the pre-reduction stage. On starting-up, the furnaces may be pre-heated by oil burners 41.

Title: Multi-turn potentiometer having a digital turns indicating device
IPC: G06M1/06
Filed: 1972-05-10
Abstract: 1352817 Counting apparatus; indicating knobs BOURNS Inc 10 May 1972 [10 Jan 1972] 21702/72 Heading G4D [Also in Division H1] A multiturn potentiometer has an integral operating knob 28 inside which is mounted a digital counter (Fig. 3) which indicates the position of the wiper 20. The potentiometer is mounted in a moulded case 12 which is a press fit into a panel P. The resistance winding 18 is on a core 16 which is located and held in the casing by moulded lugs 16s. A rotatable sleeve 24 carries the wiper 20 over the winding and engaged with the sleeve is the knob 28 in the form of a hollow shell with a transparent window 30. The counter, comprising number wheels 38, 40, 42, transfer pinions 48, 50 and a drive 34 is assembled on a base 32 which is mounted by a splined plug 32f to the fixed core 16. Gear teeth 28g inside the shell 28 engage with a pinion 38p on the drive shaft 34 to operate the counter as the shell is rotated to set the potentiometer. The gearing is such that the lowest wheel 38 rotates at five times the speed of the shell 28 but it carries the numerals 0-2-4-6-8 twice in sequence so that the numbers signify hundredths of a turn of the potentiometer. The wheel 38 also carries two transfer teeth and thus drives the second wheel 40 at one fifth its speed to indicate tenths of a turn.

Title: Improvements relating to electrically operated control means for change speed gears
IPC: F16H63/18
Filed: 1952-09-02
Abstract: 719,277. Controlling change-speed gearing. DAIMLER-BENZ AKT.-GES. Sept. 2, 1952 [Sept. 27, 1951], No. 22081/52. Class 80 (2) An electrically operated control means for a change-speed gear is characterized in that the electro-motive power is adjusted to reduce the speed of operation during downward change as compared with the speed of operation during upward change. As shown in Fig. 1 an electric motor 10 drives, through a gear 11, a cam shaft 12 which co-operates with clutch actuating levers 13 for establishing the gear ratios. A change-over switch 15 is shown by full lines in its position for downward changes. Movement of the switch to the position 15<SP>1</SP>, shown in broken lines, inserts a resistance 17 in the excitation circuit of the motor 10 which then runs more quickly in the reverse direction to effect upward gear changes. The motor armature has a separate supply 10<SP>1</SP>. In a modification the excitation of the motor is varied by using either a part only or the whole of the field windings and in another modification the supply voltage is varied by using either one half or the whole of the cells of a battery. The motor thus drives more slowly when effecting downward than when effecting upward gear changes. The change-over switch may be moved to an inoperative position automatically when the gear position is reached.

Abstract: 1376358 Inductive control systems WAGNER ELECTRIC CORP 12 May 1972 [20 May 1971] 22352/72 Addition to 1350706 Heading H4U [Also in Division E2] In an electronic lock arrangement in which the oscillation of a resonant circuit is modified by the proximity of a key circuit to produce a modified output controlling a lock, the possibility of picking the lock is precluded by making the lock operating circuit active only when the oscillator is rendered rapidly intermittently oscillatory by a cyclic spontaneous variation of the natural resonant frequency of the key. The key 10 comprises a capacitor 14 shunted by a resistor 12 in series with a diode 16 across the pick-up inductor 20. If desired, a tuning capacitor 18 may be included. The oscillator tank circuit comprises a capacitor 22, which may be adjustable and have inductors 24, 26 in series, and it is maintained by transistors 36. When the coil 20 is placed near coils 24, 26, it draws enough energy from the network to modulate its oscillation. However, as capacitor 14 fills up, the effective capacity of diode 16 and capacitor 14 is reduced, thus checking the resonance of the key circuit, until the charge on the capacitor 14 is discharged by resistor 12, whereupon the sequence starts again. Thus the resonance of oscillator I is cyclically modulated, and this frequency is detected by diodes 52, 54 in detector II. The low-frequency output is amplified at III and rectified at IV to feed a load, such as a relay at 88.
