Title: Process fot the purification of crude glyoxal
IPC: C07C47/127
Filed: 1974-06-12
Abstract: 1468855 Glyoxal purification VEBACHEMIE AG 12 June 1974 [13 June 1973] 26112/74 Heading C2C A crude glyoxal is purified by neutralizing to a pH still in the acid range, reacting with a C 1-3  alcohol to form the glyoxal hemiacetal with separation of water of hydration released by the reaction, separating the impurities from the reaction product and thereafter hydrolysing it with water at an increased temperature. The crude glyoxal may be the product of nitric acid oxidation of acetaldehyde after removal of volatile acids. The glyoxal hemiacetal may be dissolved in a water immiscible organic solvent and purified with aqueous glyoxal solution before the hydrolysis. In one embodiment water is removed from the reaction only to such an extent that salts present are just still dissolved and can be removed as the lower phase.

Title: High pressure fluid delivery apparatus
IPC: F02M59/26
Filed: 1939-09-19
Abstract: 532,774. Delivering liquids. PARKER, E. V. Sept. 19, 1939, No. 26167. [Class 102 (ii)] Fuel-injection or like liquid-delivery apparatus comprises, as shown in Figs. 1, 2, 3 and 4, a chamber 43 variable in volume by means of a reciprocating piston 31 and provided with inlet and discharge passages 17, 18, and a passage 26 which communicates under control of a valve 68 with a fluid-pressure reservoir 28. In the preferred construction, the piston 31 is reciprocated by means of a cam 58 and spring 63 in a cylinder 29, and the inlet and discharge passages 17, 18 communicate with a fuel-pump 22 and an injection-valve 23. The passage 17 communicates also through passages 42, 34 with the cylinder, and the piston is formed with a passage 36 opening into grooves 47, 48 having oppositely inclined top walls. The piston is angularly adjustable by means of a rack 56 and pinion 54 to adjust the grooves relatively to the passages 18, 42. The valve 68 has a head 73 abutting on springs 69, 74 which are adjustable by means of a screwplug 72 or an eccentric. When the piston is in the out position, fuel passes through the passages 34 into the chamber 43. As the piston rises, the passages 34 are closed, and when a pre-determined pressure in the chamber is reached, the valve opens the passage 26, and fuel is delivered at constant pressure through the passage 18 and is vented through the passage 42. When the piston reaches the in position, the valve 68 closes, the pressure in the chamber collapses, and the injection-valve 23 closes. For medium delivery, the piston is so adjusted that the passages 18, 42 are half-opened by the grooves 47, 48 whilst for full delivery the passages are opened three-quarters and onequarter respectively. Other adjustments can also be made ; for instance when heavy delivery is required, the passages 18, 42 are fully opened and closed respectively.

Title: Improvements in or relating to brakes
Inventor: PRATT JAMES HENRY
IPC: B60T13/24
Filed: 1950-10-27
Abstract: 694,582. Fluid pressure servo-brakes. GIRLING, Ltd. Oct. 22, 1951 [Oct. 27, 1950], No. 26226/50. Class 103 (i). In a vacuum servo device for master cylinder operated hydraulic brakes, the initial movement of the servo cylinder piston is arranged to cut off the master cylinder from its direct connection through the auxiliary hydraulic cylinder to the wheel brake cylinders so that thereafter all the output from the master cylinder is effective upon a plunger which operates the vacuum servo cylinder control valve. As shown in Fig. 4, the master cylinder output enters housing 16, bolted to the end of the servo cylinder 10 at connection 24. It then passes by passage 23 to chamber 19 in the housing 16, which is also connected by passage 25 to a cylinder 26 within which is a plunger 40 which operates through a pivoted lever 45 a control valve, not shown, for regulating the vacuum in the servo cylinder. The piston-rod 15 of the servo piston 13 passes through chamber 19 and then through a bush 27 and an annular sealing member 32 and then projects into the auxiliary hydraulic cylinder 28 connected to the wheel brake cylinders. When the servo piston 13 is in its retracted position, liquid may pass from chamber 19, through the axial passages 29 in the bush 27, a space 31 between the bush 27 and sealing member 32, radial ports 35 in the rod 15 and a recess 36 in its end to reach the auxiliary hydraulic cylinder 28. Initial actuation of the master cylinder thus forces a small amount of fluid direct to the auxiliary hydraulic cylinder 28. Thereafter the plunger 40 operates to actuate the servo piston 13, the first movement of which cuts off communication through the ports 35 in the piston-rod 15. Fig. 5 shows an arrangement particularly suitable for use in an automobile in which the brakes have trailing shoes in the normal forward direction of travel and wherein the servo cylinder is out of operation automatically when the gear selector lever is put to " reverse." In this arrangement the gear lever is connected by a cable 65 to a slide valve member 62 having an annular space which normally connects passages 25 and 61 from chamber 19 to the valve operating plunger 40. Movement of the member 62 by putting the gear lever in " reverse " position shuts off passage 61 so that the brakes are then applied only by direct pedal action. The annual seal 32 has been omitted from Fig. 5.

Title: System for connecting a radio station to a telephone network utilising the same frequency band for the two directions of transmission
IPC: H04B1/58
Filed: 1948-10-15
Abstract: 657,134. Telephone transmission systems. VEAUX, H. M. Oct. 15, 1948, No. 26835. Convention date, Oct. 28, 1947. [Class 40 (iv)] In a two-way telephony system utilizing the same frequency band for transmision from both ends, the frequency of the outgoing audio signal is doubled before transmission by a switch rotating over taps on a delay line through which the signal passes, the signal passing to the outgoing circuit through a high-pass filter; the incoming signal passes the other way through the delay line to the receiver and the switch prevents retransmission by reducing its frequency to a value which is blocked by the filter. As shown, speech signals from a source S1 pass through a delay line L3, taps on which are connected to contacts of a constantly rotating switch C1. The rotation period of the switch is equal to the line delay period and the pulse frequency passing through the arm of the switch and the filter A1 is doubled. A second delay line L2 and a switch C2 rotating its arm in the opposite direction restores the frequency to normal, and transmits it from S. The signal received at R from the distant subscriber passes in the opposite direction through the delay network so that the frequency at C due to this signal is zero. A multiplex system is described (Fig. 3, not shown) in which a number of sources each with its own delay line feed the arm of switch C1 through the taps along the various lines. The speed of the switch is such as to compress all the signals in a given period into the period of one, these signals being then passed through the high-pass filter D and transmitted in succession. At the receiving end the signals from a radio receiver are passed through a single delay line, the taps of which are connected successively by a rotating switch C3 to each of delay lines L1, L3 in turn and to sources S1, S3. Switch C again reduces this frequency so that filter D prevents retransmission. Specifieation 259,328, [Class 40 (iv)], is referred to.
