Title: Improvements in carriage-returning mechanisn for typewriting machines
IPC: B41J11/24
Filed: 1937-04-08
Abstract: 474,347. Typewriters. WANDERER-WERKE VORM. WINKLHOFER & JAENICKE AKT.-GES. April 8, 1937, No. 10018. Convention date, April 11, 1936. [Class 100 (iv)] Carriage-returning mechanism.-The carriage-return drive is automatically uncoupled before the end of a long run of the carriage, the carriage then running by momentum and being retarded by the carriage-driving spring, or is automatically uncoupled at the end of a short run. In the mechanism shown in Figs. 1 and 4, a rack 6 on the carriage 2 supports adjustable margin stops 7, 8 co-operating with a rocking plate 32 which is pivoted on a pin 34 on a stationary bracket 29 and is connected to a rocking arm 77 controlling the returndrive for the carriage. The stop 7 carries a pivoted arm or abutment 12 which is depressed by a spring 30 and is provided with a screw 16 normally abutting on a screw 53 on the stop. A lug 13 on the arm 12 co-operates with a ledge 65 and an incline 64 on a plate 60 which is pivoted on a pin 45, A dog 43, pivoted on the pin 45, co-operates with a projection 10 on the stop 7, and a notch 44 in a plate 33 secured to the plate 32. To couple the returndrive and thereby initiate carriage-return, the plate 32 is rocked into contact with a stop 35 by depression of the carriage-return key or, at the end of a line, by contact with the plate of a screw 23 on the stop 8. If the carriage makes a long run, the end 14 of the arm 12 engages a shoulder 40 on the plate 32, the plate is rocked towards a stop 42, the return-drive is uncoupled before the end of the return movement, and the edge 39 of the plate lifts the arm out of the notch. The carriage runs by momentum, the carriagedriving spring acting as a brake, until the plate 32 is rocked by means of the screw 16 into contact with the stop 42, and arrests the carriage. The dog 43 drops into the notch 44 and retains the plate in contact with the stop. The arm 12 is maintained in raised position by means of the shoulder 40, and the lug 13 rides under the incline 64 and thereby raises the plate 60 and then permits it to return to normal position. After a few letter-space movements of the carriage, the projection 10 releases the dog 43, and the plate 32 is moved into a position intermediate of the stops 35, 42 by means of a spring. The dog prevents the return-drive from being coupled for returnmovements which are so short as not to afford time for ensuring operation of the mechanism. During the first part of the letter-spacing movement of the carriage, the lug 13 rides on the top of the ledge 65 and holds up the arm 12, so that if carriage-return is initiated, the arm misses the shoulder 40 and, at the end of a short run, the carriage is arrested and the return-drive is uncoupled by engagement of the screw 16 with the plate 32. The mechanism can be adjusted by means of the screws 16, 53, or by altering the length of the ledge 65 or arm 12. The margin stops and the member 32 can be mounted on the framework and carriage respectively.

Title: Apparatus for regulating internal combustion engines
IPC: F02D9/02
Filed: 1974-03-07
Abstract: 1500491 Regulating IC engines D H BUTCHER 4 March 1975 [7 March 1974] 10193/74 Heading FIB A movable throttling device in the air intake of an engine, e.g. a carburetter throttle valve (59), Fig. 6 (not shown), or a throttle valve (4), Fig. 2 (not shown), in a duct portion (1) to be mounted downstream of a carburetter, is operable by a pressure responsive transducer 25, 26 connected to the intake. The transducer operates to oppose increase of air-pressure resulting from operation of the operators control member, e.g. a foot pedal (47), Fig. 5 (not shown), to increase the engine speed. Operation of the control member beyond an intermediate speed position over-rides operation of the throttling device by the transducer 25, 26 and this operation provides a reaction force at the control member. In the embodiment shown, the transducer diaphragm 27 is connected by the rod 50 and cable 44 to the carburetter throttle valve (59) and the transducer body part 25 is connected by a rod 52 and a cable 43 to the foot pedal (47). Beyond the intermediate speed position of the foot pedal (47) the abutment 64 connected to the transducer body part 26 engages a pivoted lever 63, which engages an abutment 65 on the rod 50, and end part 77 of the rod 52 has to be forced between the legs of a spring clip 75. Flanges 66 and 67 on the transducer body part 31 and the rod 50 may be locked together, by an abutment 69 on a cable 71, by the operator to render the transducer inoperative. The additional throttle valve (4) Fig. 2, is connected by a linkage (9, 10, 12) to a piston or diaphragm in the transducer (8) and a control lever (7) on the valve spindle is engaged by an override lever (14), Fig. 3 (not shown), connected by a cable (15) to the carburetter control member beyond an intermediate speed position of the control member. The transducer may be provided in a push-rod type throttle valve control linkage. The transducer may provide an electrical output signal in response to intake manifold pressure which is fed via an electronic amplifier to an electrical actuator. The electrical system may compensate for changes in engine temperature or ambient pressure and temperature.

Title: Improvements in the vapour-phase cracking of hydrocarbons
Inventor: HOLLAND WILLIAM WEST
IPC: C10G9/00
Filed: 1952-04-24
Abstract: <PICT:0729214/IV (b)/1> In the vapour phase cracking of hydrocarbons, the cracked products are quenched in a zone maintained at constant temperature and the quenched products transferred to a flashing zone, a rapid swirling motion being imparted to the products during the transfer to prevent deposition of carbon in the transfer pipe.  The process is stated to be applicable to the cracking of C2, C3 and C4 saturated hydrocarbons to unsaturated products, e.g. at temperatures of 1350 DEG  to 1550 DEG  F., but as shown a liquid charge 1 is taken to an intermediate part of column 4 where it serves as reflux and is preheated, bottoms from the column being taken to a vaporizing coil 8 and thence to an evaporator 11 from which vapours go to a cracking coil 15.  For vapour charges the evaporator is omitted.  Cracked vapours are quenched in chamber 17 to about 600 DEG  F. by an oil spray obtained from a side stream from column 4, the quantity of quenching oil being controlled by the temperature in chamber 17.  The quenched products pass via line 31 to flash tower 34, a helical vane 32 being disposed in the line 31 to impart a swirling motion to the products.  Vapours from tower 34 are fractionated in column 4.  To assist vaporization steam may be admitted to evaporator 11, flash tower 34 and column 4.ALSO:<PICT:0729214/III/1> In the vapour-phase cracking of hydrocarbons, the cracked products are quenched in a zone maintained at constant temperature and the quenched products transferred to a flashing zone, a rapid swirling motion being imparted to the products during the transfer to prevent deposition of carbon in the transfer pipe.
