Title: Improved Process for the Manufacture of Monochloracetic Acid and of its Esters.
Inventor: SIMON LOUIS JACQUES
IPC: C07C51/00
Filed: 1917-05-21
Abstract: 129,301. Simon, L. J., and Chavanne, G. May 21, 1917. Monochloracetic acid is prepared by direct hydration of trichlorethylene by means of hot sulphuric acid. The process may be carried out by dissolving trichlorethylene in highly concentrated sulphuric acid, adding water, and heating to 150- 200‹ C., or by bringing vaporized trichlorethylene into intimate contact with sulphuric acid in suitable apparatus. The chloracetic acid may be separated by distillation, or bv means of a current of hydrochloric acid gas or inert gas, or by diluting the solution and extracting with ether or other solvent. Esters of monochloracetic acid are obtained by adding an alcohol, e.g. ethyl alcohol, to the sulphuric acid solution and distilling.

Abstract: 1,103,279. Ironing-machines. SOC. POUR L'EQUIPEMENT DE LA BLANCHISSERIE ET DE LA TEINTURERIE FRANCAISES and H. L. L. JESUS. 22 Feb., 1965 [21 Feb., 1964], No. 7510/65. Headings D1A and D1S. An ironing machine comprises a rotary cylinder 1, a stationary trough 3 and a feeding device comprising a movable conveying surface 7 extending substantially over the major part of the width of the machine, the surface 7 being adapted to flatten the articles L to be ironed and to move in the same direction as the direction of movement of the periphery of the cylinder 1, and anti-adherent means 10 to prevent the articles from adhering to the surface 7 and from coming up against the front edge of the trough 3. In one embodiment, Fig. 1, the articles L are supplied by a conveyor 4, passing over a nose 5 and a return roll 6, and then move between the trough 3 and the cylinder 1 which is fitted with a felt cover 2 and rotates in the direction of the arrow F. The conveying surface is formed by a roll 7 having annular grooves (8), Fig. 2 (not shown), and is mounted in a floating manner so as to rest freely either on the cover 2 or on the articles L thereon. The roller 7 may be freely rotating or driven by an independent motor. The means 10 comprises a deflector comb fixed to the trough 3 at 11 and formed with fingers 9 which pass one into each groove (8). The ends of the fingers 9 are joined by an angle-iron 12 yieldingly applied against the trough 3 whilst the finger ends are yielding applied beneath a lip 3a. In a second embodiment, Fig. 2 (not shown), the cylinder (1) rotates in the direction (F') opposite to the direction F and the articles (L) are introduced in the downward direction by a device similar to that of Fig. 1. Bearing means (not shown) are provided to prevent the roll (7) from moving downwards and rubbing against the edge of the trough (13). In a further embodiment, Fig. 4, the feeding device comprises a number of spaced parallel narrow endless belts 34 which pass over a roll 35 driven by a motor 36 and which contact, over part of their length, the conveyor 4 and the articles L thereon. The belts 34 also pass over as L-shaped guide 37 adjustable both longitudinally and angularly. Figures 38 are fixed to the guide 37 and are yieldingly applied beneath a lip 33a of the trough 33. In any of the embodiments, air blowing means may be provided to assist in applying the articles against the cylinder 1.

Title: Improvements relating to fluid pressure vehicle braking apparatus
Inventor: SIMMONS ARTHUR WILLIAM
IPC: B60T8/18
Filed: 1960-03-03
Abstract: 903,600. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. March 3, 1961 [March 3, 1960], No. 7546/60. Class 103 (1). A vehicle braking system comprises a selflapping valve producing a pressure difference in a brake cylinder proportional to an applied force, the force being translated from a pressure dependent on vehicle load, the ratio of the translation being remotely controlled other than by train pipe pressure. The passage of main reservoir pressure (or vacuum) from a passage 14 to a brake cylinder passage 17 is controlled by a self-lapping valve comprising a closure member 18, seating 12 and hollow stem 20 open at its other end to atmosphere through an exhaust choke 23. The force on the valve is determined by the relative pressures in chambers 25, 22, 29, 21 and 30 which are separated by diaphragms 24, 27 connected to the stem 20 and diaphragm 28 bearing on the exhaust end of the stem 20. The chambers 25, 22, 29, 21 and 30 are respectively connected to brake cylinder pressure, electromagnetic valve 31, electromagnetic valve 32, atmosphere and electromagnetic valve 33. The three electromagnetic valves are supplied with fluid at a pressure dependent upon vehicle load by a valve 35 fed from the main reservoir through a non-return valve 36. In a passenger vehicle the load measurement is made automatically when the doors are opened and applied to the spring seating 39 of the reducing valve 35. The electromagnetic valves are energizable by movement of the remote driver's brake valve to apply, by combination, seven different forces to the self-lapping valve for different brake application rates, these forces being dependent on vehicle load as set by the reducing valve 35.

Abstract: 1,254,371. Random noise generators. WARWICK ELECTRONICS Inc. 13 Feb., 1969, No. 7738/69. Heading H3B. [Also in Division G5] A noise generator 70 in an electrical musical instrument comprises a noise generating diode 145 and a combination transistor amplifier and bias regulator 146. The noise diode is a reversed biased semi-conductor junction operating in the break-down region.

In a gyroscopic stabilization system (such as that described in Specification 616,516) a signal opposing the output signal of the gyro 1 is derived from the servomotor 6 or the supply thereto, the operation of the motor 6 being controlled in accordance with the algebraic sum of the two signals. Signals from an inductive device 3 are amplified at 9 and applied to a secondary variator winding 7a on a metadyne 7, the output from which supplies the motor 6. Potentiometer 13 in a D.C. supply 14, 15 may be set to produce a torque from a motor 2 opposing the precessional torque of the gyro 1 thereby governing the speed at which the motor 6 operates. Current flowing in a resistance 16 in the armature circuit of the motor 2 energizes a winding 11, thereby producing a signal at 3 opposing the signal which caused the flow of current at 6. Phase-advancing may be introduced at 19. Fig. 2 (not shown) illustrates an arrangement in which the motor 2 and signal generator 3 are combined in a single device as described in Specification 664,065, providing an A.C. signal.
