Title: Improvements in or relating to testing equipment for telephone or like systems
IPC: H04M3/32
Filed: 1937-06-25
Abstract: 497,750. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HOLT, R. S. June 25, 1937, No. 17726. [Class 40 (iv)] Apparatus for the routine testing of translators or other impulse transmitters which transmit predetermined combinations of impulses, seizes the translators in pairs and checks that the impulse combinations emitted simultaneously thereby are identical, the impulses being sent to the two windings of a differential relay. The Figure shows a pair of translators T1, T2 which provide two translations for each of four pairs of wipers, the members of each pair being effective in turn. The routiner checks the eight translations in consecutive positions of its sequence switch T and in further positions tests two more pairs of translators in a similar way. Operation of the start key SK connects up relays H, HA, S in the routiner and AA, BA in the translators. Relays AC, BC energize when impulse springs AMS, BMS are open and connect the stepping magnets TAM, TBM to those springs. As the switches rotate, the first impulse combination is sent over impulse springs ALS, BLS to the windings of differential relay A, which for correct impulsing does not operate. When the last position of the switches is reached, AB, BB pull up and release AC, BC. Relay TF energizes, disconnects S and advances T one step, whereupon the translating switches proceed to normal and AA, BA fall back. The second and subsequent impulse combinations are checked in a similar manner. In position 9 of T, relay DA energizes and seizes a second pair of translators, and in position 17, relay DB seizes a third pair. In the last position, relay RF energizes, disconnects S and lights a lamp TFL. Restoration of the key SK steps T to normal. Any spare positions of T are wired in bank tm4 to lead UE so that those positions are skipped. If relay A energizes during testing, FT operates and locks, disconnecting S and connecting up a lamp FL and alarm bell AL. The translating switches go home, but they could if desired be arranged to stop. The position of T indicates on which translation the fault exists.

Class 34(2) Wet fibrous material, such as rovings, is fed by a conveyer 14, Fig. 1b, to a perforate rotary drum 11 on which the material is retained and dried by warm air circulated by suction fans 12, 13, Fig, la, and heated by coils 9, disposed at the ends of the drum. In Fig. 2 the material is passed over and under alternate drums 17 disposed in separate housings 16 having access doors 160, the drums having doors on hinged covers in their cylindrical walls to permit access for cleaning. In a modification, pairs of drums are disposed in succeeding housings. In another arrangement, suitable for heavy materials, the material passes over the upper surfaces of a pair of drums 28, 29, Fig. 4, in one housing and then over the upper and lower surfaces of pairs of drums disposed in succeeding housings. In a further modification, drums 47, 50; Fig. 8b, are housed in a single housing, the drums 47, 48, 50 having fans 51, 52 at both ends, while drum 49 has a fan at one end only. In a further arrangement, the material is passed over a single drum 57, Figs. 11a and 11b and then into a reducer 61 from which it is fed to a housing containing drums 63, 64, 65 of narrower width than the drum 57.

Title: A new or improved method and apparatus for extracting mandrels from cavitied plastic structures
IPC: B28B7/18
Filed: 1949-07-07
Abstract: 659,252. Laminating apparatus. GONDA, D. July 7, 1949, No. 17996. Convention date, July 10, 1948. [Class 140] In the manufacture of a longitudinally cavitied plastic panel of a type such as is described in Specifications 546,089 and 562,028, complementary tapered mandrels employed for internally supporting the walls of the cavities during formation of the panel are withdrawn endwise in opposite directions from the opposite ends of the panel in successive stages by means of an improved form of the extracting apparatus described in Specification 587,834, [Group XXV], whereby similar and opposite powerful forces are applied to mandrel grip portions simultaneously but only to a small plurality of the total number of mandrels at a time. In the application of the apparatus described a panel and mandrel assembly 15 is received and firmly held by the structure shown in Fig. 7 which is slidable into place between rigid frame structures 40, 41. The assembly 15 slides into place on rollers 49 carried on runners as at 47, 48 positioned along and within gaps between table portions 43, 44, 45 which may be surfaced with hard rubber as at 46, and T-shaped grip portions 1B formed on the larger protruding end of each mandrel as at 16, 17 are all positioned within T-shaped slots formed in jaw structures 20, each comprising a rigid draw-bar 21 which is connected to a head block 22, the mandrels being so positioned or of such length that the portions 18 are differently spaced or staggered with respect 'to the adjacent ends of the panel, as shown in Fig. 4. Hydraulic cylinder and plunger devices 50 and 53 are actuated to lower the runners 47, 48 and a retaining frame structure 52, which may be rubber-faced, into the position shown in Fig. 11 in which metal corner blocks as at 56 engage the end edges of the assembly 15 to resist endwise displacement of the assembly. Hydraulic, cylinders as at 30 are actuated to cause plungers 31 to push the head blocks 22 with a force and through a small movement sufficient to initiate with, drawal of all the mandrels; during this movement, because of the staggered positions of the portions 18 the commencements of the extraction of groups of mandrels 18a, 18b, 18c occur successively. Once movement of all the mandrels has been established, i.e. after completion of the stroke of the plungers 31, less powerful plungers 32 operate to extract the mandrels a further distance and finally the extraction is completed by long-stroke plungers 33-38, actuated by cylinders 35a-38a. The hydraulic devices 53, 50 are again operated to free the panel.

Abstract: 223,633. Coward, W. M. July 16, 1923. Rotary valves; toothed gears ; expansion, varying.-Single and multiple-cylinder engines have cylindrical valve-chests in which are arranged coaxial rotatable valves for distributing the fluid, reversing, and varying the cut-off. In an arrangement for a compound engine, the inner valve 1, Fig. 2, rotated by screw and bevel gearing from the main shaft, is tapered and divided into compartments 5, 6 with peripheral ports 7 - - 11, and is surrounded by a peripherally-ported reversing-valve 13, Fig. 3, which is surrounded at one end by an angular-adjustable sleeve 30, Fig. 4. The reversing-valve has movable upwardlyprojecting blocks 20, 21 which enter ports 28, 29 of the sleeve 30. The valves 13, 30 have handles 15, 32, Fig. 7. The handle 32 may be controlled by a governor. The rotary valve 12 is held to its seat by a spring 39 adjusted by a screw held in the cover 35. Steam passes from the inlet, 58 through ports 59, 27, 16 and 7 into chamber 5. Upon either port 8 or 9 opening, the steam passes through ports 17, 28, 42 and passage 45, or ports 18, 29. 43 and passage 46 to the highpressure cylinder. The piston towards the end of its stroke uncovers ports 61 and the exhaust passes to a receiver 63 and thence through ports 64 in the valve-casing 34 and ports 22 and 10 in the reversing valve and distributing-valve respectively to the low-pressure valve chamber G and then through ports 11, 23 or 24, 47 or ports 12, 24 or 25, 48 to the low-pressure cylinder. A single cylinder engine is described wherein the exhaust steam passes from the cylinder supply passages through by-pass passage to ports in the valve casing controlled by the valve. The reversing-valve is dispensed with in non-reversible engines. The valve 1 may have the configuration of a tractrix curve, or may be provided with a conical surface having two parts of different inclination. Specification 17151/08 is referred to.
