Title: Improvements in or relating to transmitting devices for signal systems
IPC: H04L25/24
Filed: 1963-04-16
Abstract: 988,647. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 16, 1963 [April 17, 1962], No. 14848/63. Heading H4P. The invention provides means for sending to line signals free from telegraph distortion which arises from the finite extent of the output relay's contact change-over time. To compensate for this change-over time a monostable multivibrator is employed. Data bits from store 4 trigger bi-stable unit 5; mark bits cause an output on side 1 and energization of winding A of polarized relay R, and space bits energization of winding B. Movement of tongue 12 of relay R sends single current signals to line. Upon changing from a mark bit to a space bit tongue 12 changes over from contact a to contact b, and takes a short time t to do so. This is compensated by units 17, 19. Unit 19 produces a pulse at each space-mark transition which triggers monostable unit 17. This results in winding B being held energized by unit 17 for the time during which unit 17 is in its unstable state-this is adjusted to correspond to the time t-thereby ensuring that the space bits on the line are not shortened relative to the mark bits. The invention can also compensate for distortion in the pulses from unit 5. The unit 17 may be connected to a third winding of relay R.

Title: Method of forming a uniformly, or substantially uniformly, porous body of p.t.f.e.
Inventor: MORGAN VICTOR THOMSON
IPC: C08J9/26
Filed: 1957-05-14
Abstract: Porous polytetrafluoroethylene is formed by introducing P.T.F.E. into the interstices of a uniformly porous pre-formed phase, sintering, e.g. at 327 DEG C. to 400 DEG C., to consolidate the P.T.F.E. and then removing the pre-formed phase.  For example a porous P.T.F.E. body having intercommunicating spherical pores is produced by utilizing a pre-formed phase of coalesced spherical particles of bronze which are subsequently dissolved out with acid.  Alternatively the porous body may itself comprise coalesced spheres in which case a pre-phase of similar construction, e.g. of bronze, starch, salt or plastic, has its interstices filled with a suitable material, e.g. polystyrene, polyethylene, polyvinyl chloride, epoxy resins and cellulose derivatives, to form the pre-formed phase, the interstices of which, after removal of the pre-phase, e.g. by dissolution, are filled with P.T.F.E., and the pre-formed phase, after consolidation of the P.T.F.E., is then removed by a solvent inert to the P.T.F.E. Preferably not more than 90% of the spherical particles of bronze, plastic &c., should vary in size by more than a factor of 2 and other metals and metal alloys, e.g. copper, iron, or cupro-nickel, may be used instead of bronze.ALSO:Porous polytetrafluoroethylene (P.T.F.E.) is formed by introducing P.T.F.E. into the interstices of a uniformly porous pre-formed phase, sintering, e.g. at 327 DEG C. to 400 DEG C., to consolidate the P.T.F.E. an then removing the pre-formed phase.

Abstract: 384,567. Synchronizing. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Seeley, H. T. ; Yeadon, Pennsylvania, U.S.A.) June 1, 1932, No. 15553. Convention date, June 1, 1931. [Class 38 (iv).] A synchronous motor 1 is started by closing a switch 3, its field 4 being connected, to a discharge resistor 7. A relay 9, having a short-circuited delay winding, is in series with a rectifier 10 across part of the resistor 7, and opens its contacts due to the current induced in the field 4. A time-delay relay 14 closes its contacts an interval after switch 3 is closed. As the motor accelerates, the frequency of the current induced in the field 4 decreases, causing longer periods of zero current in the coil of the relay 9. When these periods exceed the delay effected by the short-circuited winding, the relay 9 closes its contacts and coil of a switch 6 is energized to connect the field to a supply 5. In a modification, the relay 9 and rectifier 10 are placed in series with the resistor 7 and are shunted by another rectifier adapted to pass the half cycle not passed by the rectifier 10.

[Class 80(ii)] In a clutch having an engaging element pivotally mounted on one clutch member and movable into and out of positive engagement with the other member, a toggle mechanism is operable against a constant bias to move the element into its disengaged position. As shown, applied in automatic operating means for aeroplane control surfaces to clutch the shaft 15 of a driving servomotor (not shown) to a drum 60 round which passes the manually-actuated control surface operating cable, diametrically-opposed pawls 20 pivoted on a driving hub 13 have teeth 24 co-acting with a bevelled toothed ring 11 on the drum 60, which is rotatably mounted on the hub 13. The pawls are actuated by toggle links 26. the clutch being normally held engaged by a spring 44 and disengaged by breaking the toggle against the spring through a manually operated pull-rope 54. Bolts 70 provide adjustment of the engaged position of the pawls, which may be rendered further adjustable by mounting them on eccentric pivots. A clutch casing 53 carried by struts 47 on the member 13 supports a stationary guide 55 for the pull-rope 54. The whole clutch assembly is detachably splined on the shaft 15, being locked in position thereon by a washer 64 drawn by a bolt 65 mounted in the member 13 into engagement with a recess 66 in the shaft and locked in position by a grub screw 66. In Figs. 3 and 4 (not shown), the toothed ring is rigid with the driving shafts and is engaged by four driven pawls spaced at 90 degrees apart. In this form the servomotor is detachably bolted to and forms one end of a fixed cylindrical housing rotatably supporting the drum externally and the pawls internally on a connecting member passing through the remote end of the casing.
