Abstract: 1,023,559. Electric selective signalling. HONEYWELL Inc. Jan. 1, 1965 [Jan. 9, 1964], No. 162/65. Heading G4H. The invention is a system for producing the ratio in digital form of two analogue quantities, which may be input and output voltages of a selected system being monitored. A first digital-to-analogue converter multiplies a constant reference voltage by the contents of a register to produce an analogue voltage which is multiplied in a second digital-to-analogue converter by the contents of a counter. Initially the register is set to 0À999, and the counter advanced until the output of the second digital-to-analogue converter equals the first of the two input voltages whose ratio is to be digitized. In equality, the contents of the counter are transferred to the register, the counter is zeroized and then the counter is advanced until the output of the second digitalto-analogue converter equals the second input voltage. The counter reading is then the required ratio.

Title: Torque-transmitting device having means for emitting a signal on exertion of a predetermined torque between a pair of rotatable members
IPC: B64C13/04
Filed: 1961-01-03
Abstract: 899,128. Controlling aircraft. BENDIX CORPORATION. Jan. 3, 1961 [Jan. 8, 1960], No. 181/61. Class 4. [Also in Group XXIV] A torque transmitting device emits a signal on exertion of a predetermined torque between two members 18, 51. Two levers 64, 75 are pivoted at 65, 77 to the coaxial relatively rotatable members 51, 18 respectively, and are biased into contact at 83, 85 by a spring 59 carried by part 58 of member 51, the spring also biasing lever 64 to close a switch 40 carried by member 51. A pin 79 on member 51 engages in an oversize hole 81 in lever 75. Torque on member 18 is normally transmitted to shaft 22 via levers 75, 64 and member 51, the stop 87 engaging lever 75 during clockwise rotation. But clockwise torque in excess of a predetermined valve, causes member 51 to lag behind member 18 and lever 77 is moved about shaft 22, pin 79 permitting rotation of lever 75 relative to arm 51 to rotate lever 64 clockwise and actuate switch 40. During anti-clockwise rotation of member 18, lever 75 is engaged by, and rotates about, pin 79 to rotate lever 64 clockwise. Member 51 extends into a recess 90 in member 18 to ensure rotation of member 51 and shaft 22 on failure of the mechanism. Actuation of switch 40 operates a relay 42, Fig. 5, to disengage auto-pilot 46 from linkage 49, 25, 26 and permits manual control 10 to control the aircraft control surfaces 32. Actuator 34 is also energised to shift a linkage ratio changer 28 to a lower position.

Title: Lubricating grease composition
Filed: 1950-01-04
Abstract: Hydroxy aliphatic ether acids of the formula <FORM:0683962/IV (b)/1> where R1 and R2 are alkyl groups of 3-12 carbon atoms, R3 is an alkyl group of 2-6 carbon atoms and m is an integer preferably less than 4, are prepared by reacting appropriate hydroxy acids with an olefin oxide, such as ethylene or propylene oxide.  A Friedel-Crafts catalyst, such as boron trifluoride or stannic tetrachloride may be used.  In an example, hydroxy stearic acid is dissolved in toluene containing stannic tetrachloride and ethylene oxide bubbled into the mixture, at a temperature of 50-60 DEG  C.  The solvent is removed by heating the reaction mixture on a steam bath.  Specified products are the hydroxyethyl ether of 12-hydroxy stearic acid, 8 - (b  - hydroxy - ethoxy) - stearic acid, 12 - (b  - hydroxy - a  - propoxy) - ricinoleic acid and 10 - (b  - hydroxy - isobutoxy) - palmitic acid. The acids may be converted to their soaps by reacting with a metal oxide, hydroxide or carbonate, especially those of the alkali metal soaps such as lithium, and of calcium, barium and aluminium.ALSO:A lubricating grease composition comprises a lubricating oil thickened with from 3-40 per cent by weight (based on the total composition) of a metal soap or mixture of metal soaps, at least one-third by weight of which is a soap of a branched-chain hydroxy aliphatic ether acid of 10-44 carbon atoms.  The acid may have the formula <FORM:0683962/III/1> where R1 and R2 are alkyl groups of 3-12 carbon atoms, R3 is an alkyl group of 2-6 carbon atoms and m is an integer preferably less than 4.  Specified acids are the hydroxyethyl ether of 12-hydroxy stearic acid, 8-(b -hydroxy-ethoxy)-stearic acid, 12-(b -hydroxy-a -propoxy)-ricinoleic acid and 10 - (b -hydroxy - isobutoxy) - palmitic acid.  The alkali metal soaps, especially lithium soaps, or calcium, barius and aluminium soaps may be used. Conventional soaps, such as the stearic acid or hydrogenated fish oil acid soaps of lithium and calcium, and low molecular weight salts, such as acetates, acrylates, propionates and furoates, and other conventional additives, may also be added to the composition.  The lubricating oil may be a mineral oil or a synthetic oil such as a synthetic ester, for example di-2 ethylhexyl sebacate or the tri-ethylene glycol ester of 2-ethylhexanoic acid.  Examples are given of the preparation of the greases.

Title: Data transmission systems
IPC: H04L1/12
Filed: 1974-01-03
Abstract: 1422291 Data transmission; error correction STANDARD TELEPHONES & CABLES Ltd 00248/74 Heading H4P In a data transmission duplex system in which the detection of an error in the transmission in either the GO direction or the RETURN direction causes retransmission cycles in both directions and in which the acknowledgement signals sent from a receiving device to a transmitting device to indicate correct reception OK or a request for the repetition of an incorrectly received data block RQ form part of the data blocks sent from that receiving device to that transmitting device, when a data block is incorrectly ceived or a data block containing an RQ acknowledgement signal is received thus demanding the insertion of an RQ in a transmitted data block, the demand is temporarily stored until this insertion has been effected and no acknowledgement signal is sent in response to any data block that may be received while the demand is temporarily stored. The data transmission system is substantially the same as disclosed in Specification 1,366,908 except that in that Specification the RQ condition is in effect dealt with almost immediately where as in the present case the RQ is retained in the RQ/OK store 17 until it can be acted on. No acknowledgement signals are sent in respect of blocks received while this condition is stored. Each transmitted signal block includes a data component from the data input, an indicator signal from 17 having two states RQ (repeat request) and OK (reception correct) and parity bits from 3. Gates G3, G4, G5 controlled by distributor 1 pass these components to the output channel and a gate G6 passes only data to a store 4. Received signals from the return channel pass through gate G7 to the data output 10, unless an error in the received signal is detected by parity check 5 or else the received indicator bit is found at 6 to be RQ. In these cases until 9 blocks G7 and initiates retransmission cycle control unit 12. This causes gate G1 to retransmit the contents of store 4. When the control 12 receives an RQ from unit 9 it passes it to the TXRQ/OK store 17 but prevents any subsequent change in that condition until after the next enabling pulse has reached G4 from the distributor 1. A retransmission cycle then proceeds as described above, however when the control 11 reaches the end of its cycle and has caused N received blocks to be discarded, it causes control 12, via the connection 20, to restore control of the store 17 to the unit 9 and also if an RQ is then supplied to the store, holds that condition in the same way as for normal data transmission, until the next enabling pulse is supplied to G4. If control 12 has completed its retransmission cycle and is ready to insert an OK/RQ signal determined before unit 11 has indicated via connection 20 that its cycle is complete, control 12 inserts RQ and following its normal operation, repeats its retransmission cycle.
