Patent GB-594393-A (GB)
Title: Improvements in or relating to hydraulic power transmissions
IPC: F16H47/08
Filed: 1939-08-08
Abstract: 594,393. Hydraulic power transmission. LAMMEREN, W. P. VAN. Aug. 8, 1939, No. 22803. [Class 69 (ii)] A hydraulic power transmission device of the kind having an impeller, a rotating vane wheel, and a guide vane wheel is constructed with a fluid-receiving vane wheel haying vanes which are adjustable to vary the angle they make with the fluid stream and simultaneously to vary in the opposite sense the effective diameter of the wheel. The invention is especially applicable to devices of the kind described in Specifications 458,143 and 485,080 in which the driving-vane wheel 4, Fig. 3, and the guide vane wheel 3 can exchange functions so as to obtain a reverse drive by applying a brake 11 to the wheel 4, the wheel 5 having a free-wheel connection 10<1> with the wheel 4, and the wheel 5 being connected to the sun wheel 6 of an epicyclic gear, the annulus 7 of which is on the wheel 4 and the planets 8 of which drive an intermediate shaft 9 which drives the output shaft 2. The vane wheel 4 'is fitted with a fixed vane 12, Fig. 5, and a movable part 13 mounted on a pivoted pin 14 which is rotated to enable the part 13 to be moved to the position shown in Fig. 5 or to be retracted so that its outer edge is within the confines of the parts 12. In its outer position the angle of impingement of the fluid is lessened but the effective diameter of the vane is increased. The vane 13 can be adjusted during running either automatically or by hand. The pivot .14, Fig. 3, is fitted with a wheel 16, having teeth disposed at an angle to the axis of rotation and engaging similar teeth on a sleeve 17 which can be moved axially by a handoperated member 29 or by a variation in the load which causes a variation in the relative angular positions of the shafts 9 and 2, which are connected by a flexible sun-and-planet gear. The relative movement causes a screw 24 to be moved axially and arms 25 on the screw move the sleeve 17 laterally. A modified form of vane is shown in Fig. 10, and the part 13 can 'be moved from the position shown counter-clockwise so that its lower edge engages the adjacent part 12. In a modification, Fig. 12, the screw connection between the sun-and-planet gear and shaft 2 is replaced by a. pin-and-slot connection 50, 51, and in this form relative movement of the shafts 2, 7 causes operation of a coil clutch 52 to obtain a direct drive between the shafts 1, 2. The vanes are then set so that the flow of liquid in the coupling ceases. The clutch 53 is of the type described in Specification 614,904, [Group XXIV]. In a further modification the vanes have parts which are adjustable about radial axes by means of pinions and racks which are adjustable by mechanism similar to that for adjusting the sleeve 17, Fig. 3.

Title: Frequency comparators
IPC: G01R13/02
Filed: 1972-05-16
Abstract: 1416883 Measuring frequency FC ROBINSON & PARTNERS Ltd 27 April 1973 [16 May 1972] 22949/72 Heading G1U [Also in Division G5] In order to compare the frequencies of two signals, a plurality of display elements are controlled by both signals such that the display pattern is determined by the relative frequencies. A reference signal is fed to pulse-shapes 10 and an equal frequency quadrature signal is fed to pulse-shaper 16. Inverters 14, 20 and AND gates 22-25 are combined to divide the cycles of the reference signal into four equal periods during which lightemitting diodes 26-29 are successively energized. The diodes do not emit however unless common line 30 is connected to the negative supply rail through transistor 31 which is driven by the unknown waveform. Thus, if the frequencies are equal the flashing pattern remains stationary, whilst if the frequencies differ, the pattern drifts forwards or backwards according to the sign of the frequency difference. The device may be used to tune pianos or guitars.

Abstract: 1342685 Rolling SIEMAG SIEGENER MASCHINENBAU GmbH 19 April 1971 [3 March 1970] 22978/71 Heading B3M A rolling head comprises cantilever-journalled conical rolls 1, each carried at an angle to the direction of rolled stock advance by a hollow shaft 12 journalled for rotation in a support 30, each shaft having slidably mounted therein a bush 5 positively secured against rotation in the shaft, means being provided for adjusting the axial position of the bush 5 in the shaft, and the respective roll or a member fixed thereto being clamped against the free end of its respective sliding bush by a stressing bolt 6 extending axially within the bush and acting in tension between an abutment 8 on the bush and the roll or member fixed thereto. To obtain the axial adjustment of the rolls, a coupling bush 20 is displaced by actuation of an annular hydraulic piston 24 so that teeth 28 of the coupling bush engage teeth 29 of the stationary support 30. An adjusting bush 16 engages the coupling bush 20 with teeth 21 and is also in a screw threaded engagement with the sliding bush 5. The hollow shaft 12 and bush 5 are then rotated by a planet shaft 15, via gears 13, 14. Since the coupling bush 20 is fixed to the support 30, the adjusting bush will remain stationary and the relative rotation between the bush 5 and the bush 16 will cause an axial displacement of the rolls. A driver 2 of the roll 1 is constructed in the shape of a cone to facilitate removal of the roll, e.g. if the driver 2 breaks at fracture position 3.

Abstract: 424,065. Making tubes &c. ROBER, E., 28, Alte Landstrasse, Kaiserswerth, D³sseldorf, Germany. Aug. 18, 1933, No. 23101. Convention date, Feb. 13. [Classes 83 (ii) and 83 (iv)] A blank b is pushed through dies a and /or rolls by a mandrel d which is pushed forward by mandrel rod f in the form of a closed ended tube which slides over a plunger i when fluid pressure is admitted to the tube f, the tube f being thereby under tension and so free from any tendency to bend. The tube f has a small end extension e which fits into the mandrel d and has a gland h at the other end. The plunger i, Fig. 3, and the tube f are supported by levers o held against them by tension springs p. The gland h, Fig. 4, has external ribs n sliding in grooves m in the guides l. Rollers g are driven to withdraw the mandrel rod f from the work, the fluid then being sucked out of the tube. In Fig. 5, the hydraulic pusher t is of too large a diameter to pass through a succession of dies q so each die is released from its holding bolts z by an extension rib u on the pusher t operating levers bb to force back the bolts z holding the die so that pins dd on the pusher can enter holes in the die and carry it along. The die holders have spring friction bushes ee to slide over the bolts dd and so remain thereon as they collect on the cone S. In Fig. 6 a winch w winds the pusher back. On return of the pusher the dies are also replaced and refixed in position automatically. To facilitate stripping the 3rd and 2nd last dies have clearance passes as in Fig. 13, and the last die has a circular pass Fig. 14 so that the tube is separated and freed from the mandrel. The means for releasing the dies from their positions and replacing them may also be applied to a pusher operated by rack and pinion. When rolls are used they are driven through a free-wheel device to allow over-run by the pusher.

Title: Improvements in or relating to dielectric heating
IPC: H05B6/62
Filed: 1950-09-21
Abstract: 677,688. Dielectric heating. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Sept. 21, 1950 [Oct. 6, 1949], No. 23145/50. Class 39(iii) A method of dielectrically heating, e.g. the glue line or lines 30, 32 of a laminated dielectric material, comprises heating the line with a plurality of strap electric fields, i.e. fields which enter and leave the work at a plurality of spaced points along the same surface of the work, and applying at least one additional strap field to heat the line at one at least of those points. In this way " cold spots " are avoided, and there is no risk of narrow electrodes indenting the work. The method is carried out by arranging the electrodes in two groups, e.g. as 8, 12, 16, and 10, 14, alternate electrodes in each group, e.g. 8, 12, being connected to opposite poles of an H.F. supply, e.g. a generator 40, and each electrode of each group lying between two opposite electrodes of the other group. In this way overlapping stray electric fields are produced. The fields of the two groups are alternately applied by means of a switch 46, the heating periods of each group being preferably equal in duration. Heating electrodes may be located on each side of the work, directly opposite electrodes being at the same potential to minimize cross fields, Fig. 5 (not shown). Each electrode group may have a separate generator alternately connectible to a commercial supply, Fig. 6 (not shown). The electrodes are formed by elongated solid metal bars.
