Title: Improvements in telegraphic systems
IPC: H04L25/12
Filed: 1929-08-21
Abstract: 337,102. Lorenz Akt.-Ges., C. Feb. 28, 1929, [Convention date]. Repeating systems using contact-making apparatus; controlling direction of simpler traffic.-At a terminal station or relay station the outgoing line is automatically disconnected from the earthed receiver or input relay and connected to the transmitting or sending-on circuit when signal-transmission begins, and the connection is reversed when signalling ceases. In an exchange switchboard and transmitter, impulses received by the input relay ER from the incoming line L1 are relayed through the armature er, jack Kl, plug and cord so as to set, up a potential-drop in the resistance Wi and thus affect the sending-on relay SR whose armature sr sends on the signals through the armature ur to the outgoing line L2. The armature ur is kept closed, during transmission from L1 to L2, by the reversing relay UR which, like sending-on relay SR and auxiliary relay HR, is polarized and is connected in a circuit comprising the condenser C. To hold on the connection ur the slow releases relay VR is provided; this relay is cut in by the armature hr at the first excitation of the relay HR, and the hold-on winding II of relay UR is thus energized through armature vr1. At the end of the message the armature vr, is released first and returns to the position shown, whereupon a reversed current from the batterv E flows in the coil II, so as to confirm the release of the line contact ur. The contact vr2 is only subsequently released. The connections are symmetrical so that signals may be passed from line L2, to line L1, in a similar manner. At a termnial station (Fig. 1, not shown) the winding ER operates, a receiving instrument for incoming messages, and a similar winding in series with the transmitter contact sr<1> operates the same receiver so as to record outgoing messages.

Title: Improvements in or relating to the production of acrylic acid
Inventor: BROWN CHRISTOPHER JOHN
IPC: C07C45/35
Filed: 1963-06-27
Abstract: Acrylic acid is prepared by reacting in a first stage propylene with molecular oxygen at an elevated temperature in the vapour phase over an oxide composition containing tin and antimony to give a reaction product containing acrolein, separating unreacted propylene from said reaction product, and passing the remainder of the reaction product substantially free from propylene into a second stage in which acrolein is reacted with molecular oxygen at an elevated temperature in the vapour phase over a catalyst comprising cobalt molybdate to produce acrylic acid.  The separation of unreacted propylene from the gaseous reaction product of the first stage can be effected by condensing said reaction product to separate acrolein as a liquid phase or by washing the reaction product with water to form an aqueous solution containing acrolein and subsequent fractional distillation of said solution to recover acrolein as a concentrated overhead fraction.  In a preferred ebodiment the propylene separated from the first stage reaction product is recycled to the first reaction stage and the remainder of the reaction product is fractionally distilled to remove materials having a lower boiling point than acrolein, the base product of said fractionation being passed together with additional oxygen, and steam or other diluent if desired, to the second reaction stage.  Reference has been directed by the Comptroller to Specifications 864,660, 878,802 and 953,763.

Abstract: 253,774. Jackson, W. J. Mellersh-, (Prosperity Co., Inc.). Oct. 14, 1925. Steam and other fluid-pressure presses.- In a garment press which is closed and maintained closed by fluid pressure and opened by a spring on release of the fluid pressure, both hands of the operator must be used to operate the controlling means for closing the press and must continue to be used until the press is closed completelv. A normally closed pressure inlet valve 15 is arranged on the same spindle 17 as an exhaust valve 23 which communicates with atmosphere, being normally open but being closed by a hand lever 32. The valve chest communicates through a pipe 19 with a cylinder 6 in which a piston 8 works, the descending movement of the piston closing the press. An extension of the pipe 19 communicates with a second normally open exhaust valve 14a which must be closed bv a hand lever 29 before the press can be closed. A restricted passage 38 places diaphragm chambers 44, 45 under pressure as soon as the piston has passed the orifice of the passage 38, and the diaphragms co-operate with plungers 46, 47 acting on the levers 32, 29 to maintain the exhaust valves and the press closed. Opening of the press is effected by releasing either of the levers 32, 29 or by releasing an auxiliary lever 50 opens a third exhaust valve 48. A pair of presses may be operated by a single operator simultaneously and in opposite phases by having the controls juxtaposed so that simultaneously with operating one pair of levers to close one press, one of the auxiliary levers may be operated to open the other press.

Title: An improved choke control for internal combustion engines
IPC: F02M1/08
Filed: 1944-12-27
Abstract: 584,297. Spray carburetters. ROBERTS, G. A. Dec. 27, 1944, No. 25871. [Class 7 (iii)] A choke valve is controlled by a spring fitted in such a fashion.that the valve has an unstable intermediate position from which it can move into either a fully closed or fully open position. During starting and warming up of an engine the valve can be set at the engine in the intermediate position in which it will remain but when the vibration of the engine exceeds a certain amount such as when a machine in which the, engine is mounted is moving the spring will move the valve into either the closed or open position. If it snaps into the closed position the operator will. have to stop the machine and move it by hand at the engine into the open position. The arrangement is particularly applicable to tractor carburetters and is designed to prevent the engine being run with a choke partially closed as is possible with the usual manual control. As shown a choke valve B has attached to its existing control arm D a triangular plate G carrying a bolt H to which one end of a spring I is connected. The other end of the spring is attached at J to a strap K fixed around the induction pipe A. In Fig. 5, the choke valve is shown in an intermediate position in which the two ends of the spring and the valve shaft C are in line. In Fig. 1 the valve is shown in the open position. When in the intermediate position the tension of the spring is prevented from moving the valve as long as the bolt H is in line with the valve shaft C and the attachment J. If the valve is moved slightly by vibration the spring exerts a turning movement and snaps it to one or other side. An existing stop prevents the spring moving the valve past the open or closed position. If the spring stretches in use the bolt H can be moved to alternative holes O or P provided in the plate G for this purpose. Also if room permits the strap K can be moved along the induction pipe to alter the spring tension. The strap can be rotated to vary the intermediate position of the valve. The triangular plate can be replaced by an arm fitted directly to the valve shaft.
