Title: Finned tubing
Inventor: MESSENGER ROBERT EDWARD
IPC: B21C37/26
Filed: 1968-06-12
Abstract: 1,207,718. Making finned tubing; coiling helices; twisting; rolling; embossing. HOWELL & CO. Ltd. 10 June, 1969 [12 June, 1968], No. 27852/68. Headings B3A, B3E, B3M and B3Q. In a method of making helically finned heat exchange tubing, a strip of fin material is passed between co-operating rollers 2, 4 which cause it to engage the external surface of a rotating tube 1 in an edgewise manner and curl therearound, the rollers cutting and/or tearing the outer periphery of the strip to form individual petals 12 at the outer edge of the fin. The rollers 2, 4 and a pair of deflecting blades 13 are mounted in a saddle which moves along the tube as it rotates. The strip is secured to the tube by forming a groove therein and closing the sides of the groove on to the strip edge. Cutting edges 10 are formed on the periphery of the face 3 of the roller 2, which edges in cooperation with the roller 4 cut into the strip to weaken its outer edge. After the strip has been secured to the tube, its outer edge is engaged by the blades 13 to bend the petals over slightly and increase the coarseness of its pitch relative to the remainder of the fin. Grooves in the roller face 3 impress buttress-like ribs on one face of the fin.

Title: Improvements in or relating to telegraphic transmission systems
IPC: H04L5/22
Filed: 1963-07-15
Abstract: 984,190. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 15, 1963 [July 18, 1962], No. 27933/63. Heading H4P. The invention provides a time-multiplex system wherein data is passed at high speed over a telephone line. Each transmission cycle includes sync. bits, address bits, and a groups of s data bits from the data sources when the telephone line is working at maximum speed. The system makes use of the fact that only a lines of b incoming lines will have data for transmission at any one time. At the transmitting end, Fig. 3, b receiving distributers 6 (b> a) severally receive data at 50 bits/sec. from data sources. Each distributer provides s data bits in parallel and one "address" bit indicating whether or not the data is to be transmitted. The distributers are described with reference to Fig. 4 (not shown) when the data sources are isochronous. If the sources are not isochronous the distributers are modified as in Fig. 5 (not shown), wherein storage triggers of Fig. 4 which are set to the data bit states during reception of data are reset when the sth bit is received. The triggers are capacitively coupled to other triggers so that, on resetting the first triggers, the other triggers take up corresponding states and remain in these states for substantially all of the time to receive the next s bits. Electronic scanner 8 scans all the bs bits in less than 20 m. sec. and scanner 7 scans the b address bits which step a counter 9 and also are transmitted over the line. The data bits are stored in an a column s row core matrix 10 under control of counter 9, and are read out and transmitted over the line at high speed and in any pre-arranged order. Timing unit 1 controls the operation of the various circuits and causes sync. bits to be transmitted prior to the address bits. At the receiving end, Fig. 6, the sync. bits set timing unit 37 in operation. The address bits are fed to register 34 and the data bits to store 36. Read out of the address bits from 34 results in counter 35 reading out the store 36 and in gates 33 being opened sequentially. Each gate in turn thus passes s bits to an associated distributer 38 which feeds the bits at low speed to the output 39.

Title: Improvements in or relating to friction brakes
IPC: B60T8/52
Filed: 1922-10-14
Abstract: 187,240. Durand, P. Oct. 17, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Band; nipping-lever and like grip; force-transmitting mechanism; actuated by running axle. - The drag of the friction members of a brake reacts upon the force - transmitting mechanism of the brake so as to maintain the retarding effect of the brake constant for any selected position of the operating lever irrespective of the increase in the coefficient of friction with decrease of speed. In Fig. 2, the member 8 upon which the cam 6 and brake element 3 are mounted is arranged to turn about the axle 1 and is connected to a fixed member 13 by a spring 12. Normally the member 8 abuts against the stop 14. If the cam lever 9 is actuated by the control, member through the rod 10 to engage the brake element 3 with the drum 2, the frictional drag on this element tends to turn the member 8 against the action of the spring 12 so as to decrease the angle e, f. g of the member 8 with the lever 9 and thus to diminish the pressure applied to the element 3. The retarding effect of the brake determined by the position of the pin g thus remains constant irrespective of the speed of the drum 2. According to the arrangement shown in Fig. 4 the cam lever 16 has a slotted end engaged by a fixed pin 18, and the rod 20 by which the brake is applied is attached to the member 8 which takes up a position such that the drag of the brake element 3 thereon counterbalances the force applied by the rod 20 which is resiliently connected to the control lever. In Fig. 6 a fiexible member 22 moved downwardly by a weight 23 is adapted to be clamped between a member 26 and a cam 29 pivoted thereto and actuated by the rod 31. As the friction increases with the decreasing speed of the member 22, the member 26 is dragged downwardly against the action of the spring 27 thereby reducing the grip of the cam. According to the Specification as open to inspection under Sect 91, the automatic regulating action of the brake may be rendered inoperative when the retarding effect is below a selected value by giving the spring 12, 27 an initial tension or when this effect is above a selected value by providing a limiting stop for the member 8, 26. This subject-matter does not appear in the Specification as accepted.
