Title: Tandem coupling means for rams of independently operable machines
IPC: B30B13/00
Filed: 1967-04-18
Abstract: 1,128,716. Press brakes. PACIFIC PRESS & SHEAR CORP. 18 April, 1967 [25 Aug., 1966], No. 17762/67. Heading B3E. A pair of press brakes in combination with their rams adjacently disposed in a common plane have a synchronizing coupling mounted on said rams across the space between them which also permits free and independent movement of each ram for individual machine operation. A press brake ram 1 operated by a pair of hydraulic piston and cylinder units 3, 5 each driven by a separate pump 11, 13 is aligned with a similarly operated ram 1 of a second press brake. The pumps 11, 13 of one ram are connected by by-pass lines 81, 83 to a bleeder valve 85 and the pumps 11, 13 of the other ram similarly connected to a bleeder valve 86, for tandem operation of the rams, the lines 83 being unblocked by a solenoid-operated valve 99. The valves 85, 86 are mounted on one ram and their control stems 93 have rollers 94 engaging a cam 109 on the adjacent ram, the valves 85, 86 functioning in reverse of one another and each shutting off when its roller 94 is midway of the cam surface 109. If the rams get too far out of synchronism a micro-switch 113 or 115 carried by one ram and engaging a cam surface 111 on the other ram causes overload release valve assemblies 41 of the leading ram to couple the pumps 11, 13 thereof to tank 26 until the other ram catches up. More than two rams 1 may be operated in tandem.

Abstract: 992, 299. Paper-making machines. BOWATER RESEARCH & DEVELOPMENT CO. Ltd. April 28, 1964 [May 6, 1963], No. 17794/63. Heading D2A. Paper making apparatus comprises a rotatable cylinder 1 around a portion of the circumference of which a foraminous band 2 is entrained, a slice 7 located to introduce paper stock between the band and cylinder and one or more felted press rolls 22, 32, which are adapted to bear against the paper web after the band 2 is entrained away from the cylinder and before the paper web is peeled from the cylinder. The foraminous band 2 is trained around rollers 3 one of which is adjustable to define a variable inlet 5 into which stock from a slice 7 is discharged the band being tensioned by a roller 3<SP>1</SP> so that expulsion of water from the web between the band and cylinder takes place as a result of pressure as well as of centrifugal force. In addition a number of press rolls 10, 11, 12 may be employed, progressively increasing pressures being applied to these rolls, the first of which 10, is preferably grooved and surfaced with resilient material such as rubber. The cylinder 1 is preferably surfaced with a material such as polytetrafluoroethylene, which may be patterned to provide paper having e.g. different properties in different directions or having high stretch properties. The felted press rolls 22, 32 may be provided with blind holes for the reception of water expelled at the nip from the web and felt, and press rolls 26, 36 are provided to reduce the water content of the respective felts 23, 33. A smoothing press roll 40 may be used between the point at which the band 2 leaves the cylinder 1 and the point at which the web 50 is peeled from the cylinder. The peeling of the web from the cylinder takes place at a small angle to the normal to the cylinder and is effected by co-operating draw felts 51 which run at a slightly greater speed than the surface of the cylinder 1 in order to take up the stretch imparted to the web in removing it from the cylinder. Suction boxes (not shown) may be used, if desired, to assist in extracting water from the paper web while it is confined between the foraminous band and cylinder. The roll 3 disposed adjacent the stock inlet 5 is usually solid but may be cellular or foraminous.

Abstract: 1377908 Regulating I C engines SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 13 April 1973 [28 April 1972] 17881/73  Heading F1B An I. C. engine system comprises an I. C. engine with a regulating device to regulate the richness of the fuel/air mixture the engine receives and a catalytic oxidation device through which the exhaust gases pass, the oxidation device comprising a catalytic chamber 16 with an air intake 15a and intake 16a and outlet 16b for exhaust gases and means to admit to the air intake 15a an air-flow proportional to the air-flow to the engine, the regulating device comprising means to measure the temperature increase between intake 16a and outlet 16b and to regulate in response thereto the mixture richness. The richness is reduced or increased according to whether the temperature difference is greater or less than a reference value. The temperature is measured in the chamber 16 by thermocouples 17 and 18, whose outputs are fed to an amplifier 19, the output of which is greater when the temperature difference between the thermocouples is greater. The output of amplifier 19 and a reference voltage provided via a potentiometer 21 are compared by amplifier-comparator 20, which delivers an output voltage to control a servomotor 22 and hence control needles 7 and 11 to regulate the mixture strength. In Fig. 2, the output of amplifier-comparator 20 is fed to a sawtooth signal generator 31 whose output is fed to comparator 32 with a sawtooth signal from generator 30 responsive to a pulse triggering device 29 which may be driven by the engine. The signal from generator 30 has sawteeth with slope determined by a potentiometer controlled by valve flap 24 in response to air-flow to the engine. The comparator 32 provides a signal from means 33 to electromagnetic valve 34 while the output from generator 31 is greater than that from generator 30. If the mixture supplied to the engine is too weak, the temperature rise in chamber 16 keeps valve 34 open longer to provide more fuel to the engine.

Abstract: 145,777. Siemens & Halske Akt.-Ges. Oct. 25, 1916, [Convention date]. Repeating and amplifying systems; thermionic relays.-In amplifying-devices having one or more amplifiers, the elements of the arrangement, through the mutual capacities of which self-excitation, speech distortion, and " whistling " may occur, are surrounded by metallic cases, which are electrically connected together and with a pole of each battery or the common battery of the device. In order to save in the number of metal casings used, if the working of the arrangement is not affected, conductors are connected to one pole of the local battery or to the system of casings, whereby they are converted into elements which do not require protection. In Fig. 2, the frames shown in thick lines represent the metallic casings in which the transformers P1 S1, P2 S2, P3,S3, and the conductors l1, l2, l3, l4 are enclosed. These cases are electrically connected together by conductors s1-s6, and are connected by means of a common conductor s7 to the negative pole of the heating- battery B, over the point R. The points O1 and O2 of the transformer coils P1 and S3 are connected to the battery B1 over the conductors a1 and a2 over the point R, which is earthed through the conductor a3. The protecting-means may be applied to amplifiers other than. thermionic, for instance microphone amplifiers, and is also a protection against any electric disturbances due to outside influences.

Abstract: 629,888. Ironing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. July 23, 1945, No. 18791. Convention date, July 27, 1944. [Class 138 (ii)] [Also in Group XXXVII] A rotary ironer comprising pressing mechanism 5 for moving a roll 1 and a shoe 2 into and out of engagement and mechanism 4 for driving the roll, is provided with a motor 3 having high and normal torque outputs, and a control 6 for shifting to the high torque output during operation of the pressing mechanism 5 and to the normal torque output during operation of the roll-driving mechanism 4. The adaptation of the control 6 shown in Fig. 2 comprises a switch 7 which, when it makes contact at 7b, connects the motor 3 across the full voltage of the power supply 9 for driving the pressing mechanism 5, and, when making contact at 7a, connects the motor 3 to a tap on the shoe-heating element 8 disposed across the power supply for driving the roll. The switch 7 is operated by a cam 10 rotatable with the pressing mechanism. In the modification shown in Fig. 3, the control switch 13 is used with a single-phase motor having a starting winding 11 and running winding 12. Under normal torque conditions, the switch 13 is closed at 13a in order to connect the full motor winding across the power supply; when high torque is required, the switch 13 is closed at 13b so as to connect part only of the motor winding across the power supply and thereby increase the torque. A further modification for use with a single-phase capacitor motor (Fig. 4, not shown) is arranged with the starting winding normally in series with a condenser. During high torque requirements, a switch connects an additional condenser in parallel with the first condenser so as to increase the phase shift in the starting winding and also the motor torque.
