Title: Improvements in massage devices
IPC: A61N1/32
Filed: 1929-06-28
Abstract: 331,098. Sherwood, W. M. F. June 28, 1929. Magneto-electric machines; driving-arrangements.-A massage roller contains a magnetoelectric machine driven by rotation of the roller. The machine comprises a stator 13 fixed to the roller 4 and having windings 14, one end of which is connected to longitudinal electrodes 10 on the roller and the other through the gearing and shaft 7 to metal handles, and a rotor 15 consisting of a permanent magnetic structure having the same number of poles as the stator. The rotor is driven by a ratchet 22 attached to the shaft 7 through gearing 16, 17, 18 loosely mounted on the shaft. The inertia of the rotor, which may be increased by a flywheel, causes the continued operation of the machine during the backward movement of the roller.

Title: Improvements in or relating to telecommunication systems
IPC: H04L12/52
Filed: 1963-05-20
Abstract: 1,026,278. Telegraphy. SIEMENS & HALSK A.G. May 20, 1963 [May 21, 1962], No. 19927/63. Heading H4P. A telegraph exchange comprises a number of channels which, when a particular combination of channels is energized, establishes communication from one subscriber to another. Broadcast connections can be set up. The system illustrated employs lines 1-5 and units SE1-SEn, EF1-EFn in an exchange which caters for subscribers Tn1-Tnn. With binary marking of the lines n = 32. When a calling subscriber Tnl wishes to communicate with Tnn he causes SE1 to be set so that each signal element from Tn1 is present simultaneously on lines 1, 2, 4, 5, in the exchange. Unit EFn is the only unit which responds to energization of these four lines, and thus signals from Tn1 pass to Tnn. Subscriber Tnn, upon receiving the calling subscriber's identity, sets up SEn at the exchange so that signals from Tnn pass through wires 3, 4, 5 only. This combination corresponds only to unit EF1 and so Tnn can communicate with Tn1. The signals from the subscribers are differentiated at PUs to provide pulse trains in which each pulse corresponds to a transition in the signals. The pulse trains from the exchange are converted to telegraph signals at PUe. Instead of being set by the calling subscriber, SE1-SEn may be set via r1-r5 under the control of a central register. Lines 1-5 can be replaced by a single line having five frequency channels.

IPC: B21C37/28
Filed: 1919-08-13
Abstract: 153,676. Thom, R. A. Aug. 13, 1919. Addition to 135,958. Tubes.-In making return bends for superheaters by forging a blank to shape and drilling intersecting holes therein, as described in the parent Specification, the forged blank is completed by two drilling operations only. In one form in which an integral upstanding curved central web 10, 10<a>, Figs. 7 and 9, merging into the main part of the forging is formed to assist in positioning the tubes for welding and to support them after welding, the blank is first shaped to the form shown in Fig. 7, with central web and inclined recesses 9, by a pair of dies 1, 2, Figs. 1 and 3, the upper die 1 of which has a pair of projections 3 surrounded by a recess 6 and between which is a central recess 5 of the shape of the web. The forging is then secured by a screw 40 in a recess in the part 15 of a jig which is angularly adjustable on a pivot 12 and secured in position by a stud 13 and nut 14. The angular position of the part 15 is determined by a reversible wedge 24, having handles 26 and mounted in a slot in the base 11. Two drill guides 21 are provided, one for each adjusted position of the part 15. The forging is held in the recess by a pivoted cover-plate 17. In another form the angular position of the part 15 is determined by a pin passing through this part and through one of two holes in the framing. The recesses 9 in the blank provided leads for the drill. When the intersecting holes have been drilled, to provide the throughway 31, Fig. 16, the end face is trued and the elements 33 fusion-welded thereto. In a modification in which the web does not project above the surface of the end of the blank, similar forging-dies are used but without the central recess 5, and a similar jig is used when drilling the holes.

Title: Improved means for delivering sliver into cans in textile machines
IPC: B65H67/04
Filed: 1947-07-28
Abstract: 636,352. Delivering textile slivers into cans. HINSON, O. C. July 28, 1947, No. 20314. Convention date, April 5, 1945. [Classes 120 (ii) and 120 (iii)] [Also in Group XXXVII] In apparatus for delivering sliver into one of a plurality of cans, the delivery is transferred from one can to another automatically, whilst the production of sliver is temporarily suspended. The suspension, transfer and re-starting of production preferably are effected upon delivery of a predetermined amount of sliver. When applied to a combing machine having a sliver receiving table 7, drawing rollers enclosed in a box 9, condensing rollers 13 and a coiler head 17, the operation of the apparatus of the invention is controlled by a yardage counter 97 driven by a shaft 99, which also drives the lower calender roller 13. When a predetermined amount of sliver has been delivered, counter 97 interrupts the supply of current to the main machine driving motor and simultaneously closes a circuit supplying a motor 95, which effects the transfer, following which the two circuits are restored to their original condition. The motor 95 moves a crank 89 through 180 degrees. This movement is transmitted through a link 75 to a rod 63 mounted between a lever 69 and a hub 65 forming part of a plate 61 bolted to the coiler head 17. The coiler head 17 is swingable about a shaft 33, under the influence of the link 75, to positions above cans, such as 47, on turn tables 100, (see Fig. 3). Simultaneously with movement of the coiler head 17, the drive to the appropriate turn table 100 is put into gear by a lever 107 associated with lever 69.
