Title: Method of and apparatus for compressing a workpiece
Inventor: KELLER J R
IPC: B21D26/14
Filed: 1969-04-17
Abstract: 1,212,953. Electromagnetic presses. AMP Inc. 17 April, 1969 [3 May, 1968], No. 19658/69. Heading B3H.  An electromagnetic press comprises a ram 24 with a die 20 to compress a workpiece against a die 50, tractive electromagnets 30, 32 to drive the ram and means to control the signal to the electromagnets to control the compression. The die 50 is mounted on a piezo-electric transducer 52 to produce a signal dependent on the compression force. The lower electromagnet 30 is fixed to the press frame 18 and has a plastics buffer plate 34 against which the other electromagnet 32 hits. The electromagnet 32 is fixed to the ram 24 and the ram is spring-biased upwards. The windings WI, WII are energized to move the ram downwards and the force exerted against a ferrule F to be crimped on to a wire L is transmitted to the transducer whose signal is fed to the power supply. Alternatively, the transducer is omitted and the windings supplied with a current pulse. The connectors C may be fed to the press in a strip which is sheared by the dies. The magnetic material of the electromagnets may become saturated before the end of the stroke. The ram force, velocity, acceleration, dwell time and stroke can be regulated by controlling the current applied to the windings. A power source (60), Fig. 4 (not shown), is connected to a pulse control device (62) which is connected to the press actuator 64, i.e. the windings. The duration of the pulse can be controlled to alter the dwell time and the amplitude of the current  to control the ram force. The pulse control device may be manually triggered by a pedal or triggered by the connector feed mechanism. If the transducer is used, Fig. 5 (not shown), the power supply (66) is connected to a gate (68) controlled by a comparator (72) with a potentiometer. The power supply may be a battery to allow the press to be portable.

Title: Dehydration by distillation
Filed: 1947-07-24
Abstract: <PICT:0630466/III/1> Anhydrous aliphatic oxygen-compounds are recovered from aqueous mixtures containing two or more of such compounds, said compounds being of the kind which form heterogeneous azeotropes with water, by feeding the aqueous mixture into a settling zone, passing the aqueous and the aliphatic compound-rich phases from said settling zone to separate fractionating zones, condensing the heads from each zone, recycling both condensates to the settling zone, and passing the bottoms from the aliphatic compound-rich phase fractionating zone, which bottoms comprise an anhydrous mixture of the aliphatic compounds, to a third fractionating zone from which anhydrous aliphatic compounds are withdrawn.  An aqueous mixture containing n-butanol and n-amyl alcohol is fed through pipe 1 into decanter 2 maintained at 90 DEG  C., wherein a lower, water-rich phase and an upper, alcohol-rich phase are present.  The water-rich phase is passed to stripper 5 containing eight plates and heated by direct steam through line 6.  The overhead, taken off through line 7, consists of a mixture of the butanol-water and the amyl alcohol-water azeotropes; it is condensed in condenser 8 and the condensate is passed to decanter 2.  The bulk of the water is removed from the system through line 10.  The alcohol-rich layer from the decanter is fractionated in eight plate-tower 11.  The same mixed azeotropes are withdrawn from the head of this tower as in the case of stripper 5. After condensation in condenser 18, the mixed azeotropes are similarly returned to the decanter. The bottoms from tower 11, consisting of a mixture of dehydrated butanol and amyl alcohol, is passed to fractionating column 21 which contains 35 plates and is operated with a reflux ratio of 3:1.  Butanol is recovered overhead, and amyl alcohol is recovered as bottoms.  The process is also applicable to feed mixtures which contain n-propyl alcohol, n-hexyl and higher alcohols, in addition to butanol and n-amyl alcohol.  The dehydration and separation of aldehydes, ketones, ethers and esters are also referred to.

Title: Improvements in or relating to tippler devices for vehicles
IPC: B65G67/00
Filed: 1948-07-26
Abstract: 653,474. Transferring vehicles into tipping- apparatus. MITCHELL, F. G. July 26, 1948. No. 19972. [Class 78 (iv)] A tippler for unloading vehicles is provided with means for arresting a loaded vehicle on the tippler platform and releasing it when unloaded. As shown in the Figure, the means includes a length of rail 15 mounted on a plunger 13 sliding in guides 14 near the wagon-supporting rail 12 on one side of the tippler platform 11. The plunger 13 is urged upwardly by a spring 16 so that the rail 15 may be depressed by the flanges 18 of the wheels on one side of a loaded truck. When the rail 15 is so depressed the plunger 13 moves to engage an arm 21 of a lever 19 pivoted at 20 to the cradle structure 11 and then to move this lever against the tension of a spring 26 so that its arm 19 engaging a laterallysliding chock 24 moves the latter to prevent the truck passing off the tippler. A further chock may simultaneously be placed behind the truck wheels to prevent the truck running back. When the truck has been unloaded by tipping, its weight does not depress the rail 15 sufficiently for the plunger 13 to engage the lever 19 so that the truck is left free to pass off the tippler. The rail 15 slopes downwardly at each end to allow the wagon wheels to run on to and off the rail without shock. In an alternative construction the plunger 13 is directly pivoted to a lever carrying a counter-balance weight replacing the springs 16 and 26, and the leverage of which weight may be adjusted. The lever is linked with a bell-crank lever operating the chock 24. In a further alternative construction the rail 15 is mounted on a laterally-extending lever biassed by a spring, the initial force of which can be adjusted and bearing on a shaped lug on a lever which it moves to operate the chock. Preferably the rail 15 is provided at one side only of the tippler so that a guide-rail may be arranged to engage the flanges 18 at the other side.

[Class 78 (iv).] In cranes or like apparatus intended primarily for lifting and launching seaplanes, boats, &c. in a rough sea, means is provided for taking in the slack of the ropes as the load is raised by the waves and holding the load in the raised position, and for releasing the ropes for lowering when desired. As shown, the hoisting ropes 5 of a slueing cantilever crane are led from the drum 4 over sheaves 6 on the trolley 7, round the fall block 8 and the sheaves 9 on the trolley, and over sheaves 10 at the end of the jib to a barrel 11. A weight 15 hangs in the bight of a tail rope 12 on the barrel 11 which is held by a brake disc 17 when the ropes 5 are payed out for lowering the block. When the brake 17 is released, the weight 15 falls taking up any slack in the ropes 5 and the barrel 11 is held in the new position by the engagement of a ratchet wheel 18 with a pawl 20 on a brakedisc 19. For lowering a boat &c., the weight 15 is initially near its lowest position, and the brake-disc 19 is held fast while the boat is lowered to the crest of the waves ; the brakes are both released to launch the boat under control by the weight 15, and the brake disc 17 is then held while the ropes 5 are payed out to release the falls. In a modification, Fig. 3 (not shown), the gear is applied to a jib crane with a single hoisting rope.

Fuel is sprayed from a nozzle 14 on to the indicator pipe by ultrasonic vibrations, the period of injection on each indicator stroke being controlled by variation of the period for which the ultrasonic vibrations are applied to the nozzle. The nozzle, Fig. 1, comprises a Piezo-electric element 1 e.g. of barium titanate, with metallized coatings 2, 3, to which an ultrasonic frequency voltage is applied from a vibrator circuit 23. The longitudinal vibrations of the element are transmitted to aluminium blocks 4, 5, between which it is clamped, and atomise fuel in the passage 11 supplied by a float chamber. The period of energization of the element 1 is controlled by an engine driven rotary wiper arm 38 co-operating with a contact 39 to close a switch 24 in the circuit 21, 22, to the nozzle and a contact 40 to open the switch. Contact 39 is carried by a ring 36 adjustable relative to ring 41 carrying the content 40 by an electric motor 35 controlled in accordance with engine speed and intake manifold suction. An engine driven alternater applies a voltage proportional to engine speed to a transformer 31, the output voltage of which is adjusted by the suction actuated device 29 and applied to a bridge circuit 34 to control motor 35. Altitude and temperature connections are applied by capsule 44 and resistance 32. At overrunning conditions a stop 50, normally limiting the travel of suction device 29, yields to allow motor 35 to cut off the fuel. At starting, ring 41 is moved manually by lever 42 to increase the fuel injection period.
