Title: System for Electronically Measuring and Recording Speeds
IPC: G01P1/12
Filed: 1967-12-07
Abstract: 1,162,128. Measuring rotational speed, electrically. KIENZLE APPARATE G. m. b. H. Dec. 7, 1967 [Dec. 15, 1966], No. 55735/67. Heading G1N. Correspondence between an indicated rotational speed value and an actual value measured by a tachometer (e.g. attached to a vehicle gear-box) is maintained by a circuit, as shown in Fig. 4. Tachometer 54 produces a D.C. voltage proportional to speed which is applied to a coil 57 on a core 55 energized with constant flux by a D. C. excited coil 56. A magneto-resistive plate 59 is located in an air-gap of the core and its effective resistance is connected in a bridge circuit which is balanced at zero speed. Flux produced by the tachometer voltage changes the magnitude of flux through plate 59 thereby changing its resistance, which unbalances the bridge. The resulting bridge output when amplified energizes a servomotor 62 which moves an indicator pointer, and simultaneously moves an armature core 63 in another air-gap, thus changing the reluctance of the magnetic circuit and hence the resistance of plate 59, until the bridge is rebalanced, when the pointer will indicate the correct speed value. The armature may be coupled to a recorder stylus. In an alternative embodiment Figs.2, 3 (not shown) there are two separate magnetic circuits, in the first of which the tachometer voltage controls the resistance of a first magnetoresistive plate and in the second movement of an armature coupled to the servomotor and indicator pointer controls the resistance of a second magneto-resistive plate. The resistances are connected in different arms of a bridge the unbalance voltage of which energizes the servomotor as before. In the embodiment Fig. 2 (not shown) the armature comprises two parallel relatively displaceable elongated tapered plates each having curved edges of paraboloid form. In Figs. 5, 6 (not shown) the armature comprises a pair of cam discs. Temperature dependent magneto-resistors may be utilized, to provide temperature compensation.

Title: Coded data-handling apparatus
IPC: H04L5/16
Filed: 1973-12-28
Abstract: 1457267 Data transmission; systems utilizing differing word lengths HONEYWELL INFORMATION SYSTEMS Inc 28 Dec 1973 [2 Jan 1973] 60016/73 Heading H4P A duplex transmit/receive unit has features common to both operations and may be adapted manually for characters of differing bit lengths, e.g. 5-7 bits plus parity bit if required. The receiver part receives characters through an interface (not shown) on line 24 through connector parts 22 into register 26 and which are passed into register 30. Start of each message is preceded by two sync. characters, the configuration of these, e.g. SYN/SYN, or DLE/ SYN determining whether the receiver operates in a "normal" or "transparent" mode; the first sync. character is detected by comparator 32 and second sync. character identified by comparator 34, both comparators being fed with relevant characters through connector part 22 and appropriately primed gates 40, 48. Output of comparators 32, 34 enables AND 44 thus setting flip-flop 46 and enabling counter 50 for succeeding clock pulses, up to 8 in number and which then resets. Each reset primes AND 38 which indicates receipt of a full character in SR 26 and which may be passed to buffer 36. SR30 also receives incoming information characters but is not utilized other than for sync. purposes. If there is no overrun and a unit (20, Fig. 1, not shown) does not block, AND 38 is enabled and a signal is sent to a central processing unit (CPU 10) to indicate that the character is ready for transfer and (CPU 10) returns an acknowledgment which resets flip-flop 52. AND 38 also enables buffer 36 to receive a character from SR 26; at the same time parity check 54 and SR full detector 56 are enabled together with a code convention unit (20, not shown) for the purpose of detecting the type of character and indicating identity to (CPU 10). An overrun signal is generated when buffer 36 is full and SR 26 has also received a character and cannot transfer to 36, by detectors 56, 58 which may be all zero detectors if 26, 36 are reset to all zeros after each transfer; 56, 58 enable AND 60 which indicates to CPU that the character in 36 is a valid one but the next character will be invalid as it will be overwritten by bits of the next received character(s). Retransmission may be requested. The overrun signal also, through inverter 62, disables AND 38. Retransmission is also requested if parity is incorrect. As a DLE character is normally blocked from (CPU 10), if a data character identical to DLE is to be transmitted when in transparent mode, two successive DLE characters are sent, the first being blocked and the second passed to (CPU 10). Connector parts 22 (some parts not shown in Fig. 2) form part of a connector or set of connectors whose external connections may be changed by jumper wires (i.e. 23) to alter character length, e.g. from 5 to 6 or 7, plus parity bit if required. The code convention unit may provide a cyclic redundancy check.

Abstract: 1280168 Treatment of synthetic yarns TMM (RESEARCH) Ltd 1 Jan 1971 [16 Dec 1969] 61237/69 Heading D1F A method of treating a synthetic yarn comprises advancing yarn over a heat transfer element by the passage of the yarn at one end or at each end of this element over guide means which causes a reversal of the direction of travel of the yarn over the element and a transfer of the yarn from a path in contact with one side of the element to a path in contact with the other side of the element and which is stationarily arranged or arranged to revolve at a speed less than that of the travelling yarn, and using twisting means to impart to the yarn upon leaving the element a twist which runs back to the yarn passing over the element beyond the guide means or beyond at least the last contacted guide means. Before advancing the yarn over the heat transfer element the method may include the additional steps of drawing the yarn. The method may be carried out in the apparatus shown in Fig. 1 wherein yarn Y is passed over feed rollers 1 and 2 and then passed in contact with one side of the heater 3. The yarn is passed around the stationary guide pin 4, along the other side of the heater, around pin 5, again along the first referred to side of the heater to the false-twisting device 6, from which it is taken up by delivery rollers 7 and 8.
