Title: Synchronous self-shifting clutch
IPC: F01D19/00
Filed: 1972-10-31
Abstract: 1409810 Ratchet clutches SSS PATENTS Ltd 22 Oct 1973 [31 Oct 1972] 50203/72 Heading F2C In a synchro self-shifting clutch wherein a pawl and ratchet mechanism 5, 18 between an intermediate member 14 and one clutch member 1 initiates clutch engagement by moving the intermediate member 14 helically along another clutch member 6 to bring clutch teeth 16 on the intermediate member into precise interengagement with teeth 4 on the clutch member 1, a locking ring 26 carried by the intermediate member 14 or the clutch member 6 coacts with teeth 30 on the clutch member 6 or intermediate member 14 to lock the clutch engaged. The locking ring 26 is rotatable against the bias of a spring 39 relative to the intermediate member 14 and, in the clutch disengaged condition, has teeth 29 meshed with the teeth 30. During clutch engagement helical movement of the intermediate member 14 causes the latter to rotate relative to the locking ring 26 and clutch member 6 so that, when the teeth 29 disengage from the teeth 30, the springs 39 rotate the locking ring 26 relative to the clutch member 6 to a position in which the teeth 29, 30 are aligned to prevent clutch disengagement. When the clutch is engaged liquid is fed through ducts 36, 33, 32, 31, 38, 37, to a chamber 28 between the intermediate member 14 and locking ring 26. When the clutch member 6 exceeds a predetermined speed the centrifugal pressure developed in the chamber 28 rotates the locking ring 26 to a position in which the teeth 29, 30 can interengage and thus permit normal clutch disengagement on overrun. The clutch member 6, 1 may be respectively connected to a gas turbine and a generator. Initial rotation of the generator shaft 3 in a direction opposite to its normal direction of rotation engages the clutch which is locked engaged to permit subsequent rotation of the generator shaft in its normal direction of rotation to be transmitted to the gas turbine for starting purposes. When the gas turbine is started and drives the generator at a speed greater than the predetermined speed, the clutch is automatically unlocked to permit normal operation.

Abstract: 1,116,757. Laying submarine conduits. SOCIETE D'ETUDE DU TRANSPORT ET DE LA VALORISATION DES GAZ NATURELS DU SAHARA S.E.G.A.N.S. 10 Nov., 1966 [10 Nov., 1965], No. 50442/66. Heading F2P. To reduce the tractive force required in laying a conduit C on the sea bed, roller devices r 1 , r 2 , r 3  etc., are clamped to the conduit so that when it is pulled along by cable T it is constrained by them to follow a heavy guide cable L previously laid along the required path. If the conduit is not naturally buoyant it is made so by using floats. When more than one length of conduit is to be laid, the most remote from the land site Ch is laid first so that succeeding sections can be more accurately aligned. If required, scrapers can be dragged along the guide cable L before the conduit is laid to dig a trench in the sea bed in which the conduit will lie.

Abstract: 1438690 Printed circuits SONY CORP 2 Aug 1973 [10 Aug 1972] 51910/75 Divided out of 1438689 Heading H1R Electronic components, e.g. LEDs 1 are mounted on a non-conductive plate 6 by forming a conductive lead pattern 16 on the plate, forming an apertured resin layer 30 over the pattern, setting the components in their required positions on the plate in the apertures and pouring a conductive resin 41 into the apertures to connect the components to the leads. An alpha numeric display device comprises a plurality of LED arrays, a conductive pattern on a transparent non-conductive plate 6 providing individual leads for one electrode of each diode and a common lead for the other electrode of all the diodes of each array and a plurality of leads running along the device above the pattern interconnecting the one electrode of corresponding diodes in each array via the individual leads. Each array comprises seven segments of a figure-of-eight, a decimal point and a dash in space 29. The conductive pattern comprises segments 11 ... 20, the last providing the common lead; each of these segments includes a tab 11<SP>1</SP> ... 20<SP>1</SP>. The pattern is covered by a resin layer 30 with apertures for the LEDs and over each tab. The LEDs 1 are inserted in the apertures and the spaces beneath the LEDs are filled with photo-sensitive resin 36 to secure them and to prevent conductive resin subsequently entering these spaces. The resin 36 is coated over the assembly and drawn into the spaces by lowering the air pressure. The resin is illuminated through a mask over the plate 6 to harden the resin only under the diodes. Further resin layers 36, 40 are added. Grooves are formed in these layers extending over the tabs and conducting strips are inserted therein. A conductive layer 41 is added to interconnect the diode electrodes and strips to the conductive pattern tabs. A glass plate 43 with a reflecting surface 44 is finally added.

Title: Antiskid control systems with an electrical signal generator responding to rotary deceleration
Inventor: LEIBER HEINZ

Filed: 1968-11-06
Abstract: 1,243,835. Antiskid control. TELDIX G.m.b.H. 6 Nov., 1968, No. 52595/68. Heading F2F. [Also in Division H1] Antiskid of vehicle wheels is controlled by a switch device which, when the brakes are applied, causes the brakes to be actuated and released alternately such that the variation of the rotary speed of the wheels with time is aperiodic. As shown, the switch device includes a plate 5 secured to a vertical shaft 1 which is driven by the vehicle, and a mass 11 rotatable about the shaft 1, the mass 11 being provided with a contact 12 and a stop pin 13, which pin 13 is bounded by leaf springs 16, 17 to resiliently restrain rotary movement of the mass relative to the plate, which rotary movement is limited by a groove 19 in the plate. A spring-urged lever 21 is pivoted on plate 5 and is provided with a contact 22, movement of the lever 21 outwardly being restricted by a raised edge 25 of the plate. A further contact 29 is also provided on plate 5. During forward movement of the vehicle, the device is rotated anticlockwise and the lever 21 is urged outwardly by the centrifugal force. When the brakes are applied, the plate 5 is decelerated and the mass 11 rotates relative to the plate thus moving contact 12 towards contact 22. As the plate slows down, lever 21 moves inwardly until contacts 12, 22 touch causing the brakes to be released, the mass 11 then experiencing an acceleration so that contacts 12, 29 touch which maintain the brakes released. When the mass 11 rotates at the same speed as plate 5, i.e. the vehicle wheel speed, the brakes are caused to be actuated again and the cycle repeats itself, each successive cycle being smaller as the vehicle slows down, as shown in Fig. 4. Vgr represents the rotary speed when the contacts 12, 22 just touch, V represents the state of the contacts 12, 22, and B of the contacts 12, 29. The contacts actuate an inlet and outlet solenoid valves of a fluid pressure system for operating the brakes, Fig. 3 (not shown) The curve P in Fig. 4 represents the variation of fluid pressure during the braking operation. In alternatives, the contacts may be replaced by electronic switches (B), (V 1 ) and a speed-dependent switch (G) may be provided in series with the deceleration responsive switch (V 1 ), Figs. 5 and 6 (not shown).
