Title: Variable speed bi-directional control mechanism
IPC: B21D3/10
Filed: 1973-03-09
Abstract: 1426244 Machine carriage control USS ENGS & CONSULTANTS Inc 9 March 1973 [9 March 1972] 11489/73 Heading B3E A drive control for a carriage 14, Fig. 1, of a machine for propelling the carriage in either of -two directions comprises a rotatable shaft 100, a centering cam 101, Fig. 5, rotatable by the shaft having two symmetrically arranged shoulders 102, biasing devices 106 bearing against each of the shoulders to maintain the cam and shaft in a predetermined position when the control is inoperative, a device for rotating the shaft in both directions from the predetermined position, devices 116, 117, Fig. 3, operable by rotation of the shaft in one direction to cause movement of the carriage in that direction, and a device responsive to the extent of rotation of the shaft in either direction to vary speed of movement of the carriage. The machine e.g. a rail manipulator for a gag press, comprises a base 10, rails 12, a manipulator head 24, and a reversible hydraulic motor 15 for propelling the carriage along the rails. A bevel gear 112 is fixed to the end of shaft 100 and engages a bevel gear 113 fixed to a shaft 114 carrying cams 116, 117 and a lever 119. The cams control microswitches 120, 121 for controlling the direction of movement of the carriage. The lever 119 is connected to a cable 124, via a clevis 123, to operate a servo valve 125 for controlling the speed of the carriage. Movement of a lever on the shaft 100 causes rotation of the shaft and subsequent rotation of bevel gears 112, 113 and shaft 114. The amount of rotation of shaft 114 controls the opening of the servo valve and hence the carriage speed. When the lever is released, springs in.a housing 107, associated with spring- loaded plungers 106, cause the latter to return to their equilibrium position and rotation of the shaft 114 ceases and the carriage stops.

Title: Process for the manufacture of acrolein from tetrahydrofurfuryl alcohol
IPC: C07C45/59
Filed: 1943-07-20
Abstract: A process for the preparation of acrolein from tetrahydrofurfuryl alcohol comprises contacting tetrahydrofurfuryl alcohol in the vapour phase with a dehydrating catalyst comprising aluminium silicate or granular titanium dioxide and exposing the alcohol when in contact with the catalyst, or the catalytic reaction products to a temperature exceeding 400 DEG  C.  The reaction may be carried out as a single stage process by contacting tetrahydrofurfuryl alcohol in the vapour phase with the dehydrating catalyst at a temperature exceeding 400 DEG  C., or as a two-stage process by first contacting the alcohol with the dehydrating catalyst to form 2.3-dihydro-1.4-pyran and water, at a temperature below 400 DEG  C., and then heating the dihydropyran to a temperature above 400 DEG  C. to yield acrolein and ethylene; this may be carried out by passing the dihydropyran over heated broken glass above 400 DEG  C.  Examples of both processes are given; reference is made to the use of inert carrier gases, carbon dioxide and hydrogen being specified.  In the Provisional Specifications, the single-stage process is carried out in the presence of a mild dehydrating catalyst of such a nature that it only reaches its maximum activity at a temperature above 400 DEG C., whilst the two-stage process is not limited to the use of particular dehydrating catalysts.

Abstract: 265,912. Automatische Fernsprech- Anlagen-Bau-Gres. Feb. 15, 1926, [Convention date]. Automatic exchange metering systems and selectors.-In a system in which the selectors on release continue their rotary motion to the end of their banks, the metering circuit is completed by a rotary off-normal spring w2 (preferably of the first selector), which is closed when the wipers reach 11th terminals, and is broken by the restoration of off-normal springs such as the vertical springs k2 or the springs w1. Construction of selectors. The wipers f are carried by a notched bar r which co-operates with the vertical magnet and runs in a guide c in a disc carried by the rotary ratchet. Vertical springs are controlled by a member Ko. During rotary motion the wipers are maintained in their raised position by engagement of a notch in the bar r with a fixed guide. At the first rotary step, pins d1, d2 release the springs w1, w2 and at the 11th step the next pin d2 restores the springs w2 again. After one or more further steps the springs w1 are restored and the notched bar now falls down the recess c1. At the lowest position a notch on the bar r enables it to be restored to its initial position while the rotary ratchet remains stationary. Circuit arrangements. When the calling subscriber hangs up, line, release and switching relays A, B, P1, fall back and a self-interrupting circuit is closed for the rotary magnet D1. When the wipers reach their 11th terminals the springs w2 complete a circuit for the meter Za provided the contact z (which is controlled, by means not described, to decide whether metering is to take place or not) is closed. On the next step, the springs w1 disconnect the rotary magnet and the wipers are restored to normal, the vertical springs k2 opening the metering circuit and the springs k1 breaking the circuit of relay R which releases relay P whereupon a homing circuit is made for the line switch.
