Filed: 1970-05-12
Abstract: 1308654 Vehicle testing FAV SRL 12 May 1970 [28 Aug 1969] 22862/70 Headings G1W An apparatus for testing the brakes or engine of a vehicle comprises two pairs of rollers 1, 2 and 3, 4, a respective tachymetric dynamo 12, 13 coupled to each pair of rollers, a respective rotatable electrical machine 8, 11 coupled to each pair of rollers and adapted to function selectively as a motor or a generator, and a control device which controls the current supplied to or from the electrical machines when functioning as motors or generators respectively, so that the difference between the inertia the vehicle would have at the simulated test speed and the inertia of the rotating parts of the test bed at the test speed is automatically and exactly compensated for under conditions of varying speed by the torque of the electrical machines. The two rollers in each pair are coupled by a drive belt 6, 9 and rollers 1 and 3 may be coupled by an electro-magnetic clutch 16. Detector heads 18, 18' are provided to control revolution counters which give an indication of the symulated distance travelled to stop the vehicle when the brakes are applied. Idler rollers 19 and 20 may be lifted by an oil powered jack 22 to lift the vehicle wheels off the drive rollers. In a further embodiment, each electrical machine is provided with two flywheels 38, 39, 40, 41, Fig. 2-2' (not shown), which may be connected to rotate with the rollers by electro-magnetic clutches. The electrical machines 8, 11 may be used simply as generators to determine the power output of a vehicle, and friction power less in the vehicle may be determined by using the machines as motors. The tachymetric dynamos may be employed to produce direct readings of deceleration.

Title: Process for the recovery of gas tars from their emulsions with water
IPC: C10G33/04
Filed: 1929-07-29
Abstract: 328,516. Ripley, R. R., and Schwarz, S. C. July 29, 1929. Tar.-In the recovery of tars from their aqueous emulsions, a relatively small proportion of a demulsifying agent, such as a water-soluble alkali, is added, and the mixture is rapidly heated to boiling under atmospheric pressure to assist in the intermixture of the ingredients. Heating is continued to a higher temperature under increasing pressure to prevent vaporization and at a point below cracking until the water particles reach the desired coalescence, when heating is discontinued and pressure gradually released to allow separation of the tar into a distinct layer. A settling period of 12 to 36 hours is stated to separate the more stubborn emulsions. Caustic soda solution is mentioned as a demulsifying agent and the quantity specified is approximately six-hundredths of one per cent by weight of caustic to tar emulsion. Maximum temperature and pressure specified are approximately 320‹ F. and 75 lbs. per sq. in. gauge pressure. The apparatus comprises a container a, preferably a horizontal cylindrical boiler of 5,000 gallons capacity, connected to tanks k and l containing emulsion and demulsifying agent respectively by a common pipe m<2>, and to outlets w, x by pipe v. Steam coils c in the bottom of the container heat the emulsion. A number of test outlets r<1> to r<10> are provided, and the condition of the emulsion is judged by drawing off samples at different levels.

Filed: 1944-11-23
Abstract: 576,614. Impulse generation. BRITISH THOMSON-HOUSTON CO., Ltd., and GRIFFITHS, L. Nov. 23, 1944, No. 23340. [Class 38 (ii)] [Also in Group XXXVII] High-tension electrical apparatus for intermittently electrifying fences comprises an induction coil with a condenser energised by a battery through contacts, the attraction of an armature by the energised induction coil opening the contacts and impulsing an oscillating spring-biassed balance wheel which closes the contacts on each return movement. When contact 4 on a pivoted armature 8 engages contact 5 on a pivoted lever urged in a counterclockwise direction by spring 10 the primary of an induction coil 2 is energised and core 1 attracts the armature 8. This moves up from the stop 14 to open the contacts and its free end impulses a projection 15 on a balance wheel 7 which partially rotates and then returns, urged by a spiral spring 17. Pin 16 strikes the lever 9 to cause re-engagement of the contacts 4, 5 thus energising the induction coil 2 and repeating the cycle. High-voltage impulses are induced by each make-and-break in the secondary of the induction coil 2 which is earthed to core 1 at one end and connected to the fence at the other.

Title: Improvements in or relating to twin-conductor transmission lines for ultra-high-frequency electromagnetic energy
IPC: H01B11/18
Filed: 1948-09-06
Abstract: 656,672. High-frequency transmission lines. SPERRY CORPORATION. Sept. 6, 1948, No. 23452. Convention date, Sept. 5, 1947. [Class 40 (viii)] In a high-frequency transmission line in which two conductors are fixed relatively to each other by a structure which is electrically resonant at the transmission frequency of the line, impedances are placed in the line on each side of this structure which exhibit series resonance at the transmission frequency. At the exact design frequency these impedances are zero and do not affect the operation, but at frequencies varying from that designed, these impedances reduce the standing waves produced by the supporting structure and permit the line to be used for a broader band of frequencies than would be otherwise possible. The examples show the structure as a stub 13 on a coaxial line. In Fig. 6 the inner conductor of the line on each side of the stub includes an open-ended coaxial line section 30 or 31 of length #/4 where # is the design frequency. In Fig. 10 the outer conductor of the line includes closed-ended sections 35 and 36 of length #/2. It is also possible to use closed-ended sections of #/2 length in the inner and open-ended sections of A4 in the outer.

Title: Improvements in winding machines for textile threads and yarns
IPC: B65H54/32
Filed: 1925-09-22
Abstract: 258,428. Schweiter, H., and Maschinenfabrik Schweiter Akt.-Ges. Sept. 22, 1925. Winding-machines.-In traverse mechanism of the kind in which the thread-guide rod is reciprocated by two spring-controlled segmental nuts which are alternately engaged with one of two oppositely rotating screwed spindles by means comprising a finger co-operating with a templet, the templet is made displaceable in two directions perpendicular and parallel to the axis of the thread-guide rod. The movement of the templet perpendicular to the axis of the rod is effected manually to vary the length of cop wound and the movement parallel to the axis is derived from a reciprocating part to shape the ends of the cop. Two screwed spindles 2, 3 geared by wheels 5, 6 and driven from a pulley are mounted in a casing 1 and are engageable by segmental nuts 9 carried by a carriage 8 rotatable on, but axially fixed to the thread-guide rod 7. An upstanding arm 10 on the carriage is adapted to engage, when displaced from its central position, inclined bars 12 carried by bellcrank levers 14 attached to springs 15. A wedge-shaped contact finger 16 projecting from the carriage 8 rides above or below a templet 17 as the carriage and the guide rod 7 are traversed by one or other of the nuts 9, its position, i.e. from above to below or vice versa, being reversed at the end of the templet by the stress put on the spring 15. The templet has tapered ends and is carried by an arm mounted in a slide 20 and adjustable to or from the rod 7 by a screw 21 having a milled head 22, so that by varying the distance of the templet from the rod 7 the length of contact between the templet and finger 16 and the length of the cop is adjusted. The slide 20 is displaced longitudinally by a pin 27 engaging a transverse groove in the slide and mounted eccentrically in a shaft 26 rotatable in a bracket 18. The shaft 26 is rotated step by step by a ratchet 31 engaging a toothed wheel 29 on the shaft and oscillated by a lever 30 engaged by a stop 33 on a rod 32 secured to the rod 7. The displacement of the slide 20 and its templet 17 causes the ends of the bobbin to be tapered in form. The control wheel 29 may be kept stationary when it is desired to wind bobbins without tapered portions.

Abstract: 1456169 Screw presses ELECTROLUX AB 2 June 1975 [13 June 1974] 23778/75 Heading B5F [Also in Division B8] In a screw press comprising a piston 10, a support 25 and a vertically movable part 17, 21, a screw 13 journalled in the piston 10 and threaded rods 23, 24 journalled in the support 25 each engage screw threads in the part 17, 21. As applied to a household waste compactor, the yoke 21 and spacer 17 are interconnected by rods 18, 19, and drive is by an electromotor 35 and a toothed belt 26 to a pinion and gears 30, 31 on the rods 23, 24. The screw 13 and one or more shafts 14, 15 are keyed together in telescopic relationship, Fig. 4 (not shown), being driven from the pinion through a slipping coupling 37. Thus fast movement of the piston effected by rotation of the coarse-pitch screw 13 and the fine-pitch rods 23, 24 is followed by slow movement when the coupling 37 slips upon increased pressure. Maximum pressure sensed by a power relay in the motor circuit reverses the motor. Reversal upon insufficient or no pressure on the piston is caused when the yoke 21 compresses springs 27 at the ends of the rods 23, 24. The yoke 21 may be guided on bars (not shown).
