Abstract: 1,031,794. Electromagnetic relays. CIE ELECTRO-MECANIQUE. Jan. 17, 1963 [Jan. 29, 1962], No. 2169/63. Heading H2B. An armature 2 pivoted in a half bearing 3 is prevented from sticking to a U-shaped yoke 1 by a non-magnetic, e.g. stainless steel, bar 4 provided either on the pole face 1b nearest to the pivot 3 or as shown on the face 2b of the armature. As shown, the bar 4 is secured by welding or brazing in a recess in the lower part of face 2b of the armature and has a cylindrical surface, which is proud of the face 2b, about which the armature rolls during the latter part of its closing stroke. Alternatively, the bar may be flat and roll about a cylindrical surface on pole face 1b In another embodiment the bar is secured in a central slot in face 2b and is in the form of a prism or cylinder. The other face 2a of the armature may be flat or curved so that it only bears against that part of the pole piece la which is surrounded by a phase shifting ring (not shown).

Abstract: 747,877. Electroluminescence. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 29, 1954 [Feb. 3, 1953], No. 2768/54. Class 39 (1). [Also in Group XL (c)] An electroluminescent lighting panel is supplied with alternating voltage from an oscillator comprising capacitance and resistance and provided with inductive feedback. The panel 1 which also acts as a capacitor is connected in parallel with a tapped inductance 3 connected to the cathode grid and anode of a directly heated triode 2. Tapping 4 is connected to mains terminal 8 and capacitors 5, 6 and resistance 7 are connected to grid and cathode as shown. The circuit produces a peaky voltage curve with steep edges, the characteristics of which are discussed. In a modification (Fig. 3, not shown), one side of the panel is connected to the mains, and a switch permits the disconnection of the oscillator and the application of mains voltage for low illumination. The application of oscillator and mains voltage together reduces flicker. Two oscillations operating in phase opposition may also supply the electroluminescent panel (Fig. 4, not shown).

IPC: D04C5/02
Filed: 1924-02-05
Abstract: 224,773. Goodley, C. Feb. 5, 1924. Lace.-Square or fillet net L is made on a curtain machine provided with one set of spool threads A controlled by a single guide bar B at the same time as ordinary clothing effects and ties M, either description of work being made at any part of the curtain at will. The bar B moves one gait to the left when the carriages E are in the back comb bar F, then rests for a moment and moves two more gaits to the left. It moves similarly to the right when the carriages are in the front comb bar G. Ties or clothing effects are thus made, but if interceptors H are moved into the spool and warp threads A, C when the carriages are in the comb bar F, these effects are suppressed. At places where the square or fillet net L is to be made the interceptors H may enter the threads on the second and fourth motions, when the carriages E are in the comb bar G and also on the seventh and ninth motions when they are in the comb bar F and may be held out of action on the other motions. Each spool thread A intercepted in this way moves three gaits to the left on the first motion, pillars with the same bobbin thread on the second to the fifth motion, moves three gaits to the right on the sixth motion and pillars for the following four motions. For a net that repeats in more or less than ten motions the movement of the interceptor is corres. pondingly varied.

Abstract: 289,959. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Feb. 4, 1927. Acetic and other anhydrides.-In the production of the anhydrides of acetic acid, its homologues and halogen derivatives by the reaction of the acid chloride (produced in situ) and salt, the reaction is effected in presence of the free acid, and the source of chlorine is chloride of silicon, tin, or titanium or a mixture of such chlorides. In an example, acetic anhydride is made by mixing glacial acetic acid with dry sodium acetates in a closed vessel, and adding silicon chloride while stirring. When the pressure, which at first rises, has again become normal, the mixture is distilled, preferably under reduced pressure. The acetic acid may be replaced by the first fraction of the distillate. The velocity of reaction is favourably influenced by using "silicon chloride mixed with stannic or titanic chloride or both.

Abstract: 547,392. Hydraulic transmission of power. VICKERS. Inc., and VICKERS, H. F. March 12, 1942, No. 3250. [Class 69 (ii)] A hydraulic system for operating grading- machines for road making, bulldozers, snow ploughs, hoists, or forcing presses comprises a pump 3, Fig. 15, for supplying liquid under pressure to two or more valves 1, 1a, connected in series each of which controls the supply of liquid to one of a series of cylinders 24, 31 of motors for operating loads 26, 33, the arrangement being such that the valves can be manipulated to operate the motors independently or collectively in the desired direction. The construction of the valves 1, 1a is shown in Figs. 4 and 5 which represent longitudinal sectional views through different planes. The valve 1 is formed with a main body part having an inlet passage 11 and an outlet passage 12 connected to the valve 1a, and with outlet passages 20, 21 connected to the cylinder 24 of the first motor. The valve 1a is similarly constructed its inlet 13 being connected to the outlet 12 of valve 1, and its outlet 16 being connected back to the tank 2 which supplies the pump 3. Each valve is provided with a self centring core with ends 43, 43a which pass through caps 40, 41 screwed to the valve body, the arc being fitted with apertured washers 82, 83 which in the neutral position of the valve core engage shoulders on the cap 41 and the body and position the core as shown in Fig. 4 so that the liquid passes direct to the outlet without passing to the motors, and when in this position the motor pistons are locked in position. By moving the valve core to the left from the position shown in Fig. 5 the pipe 23 is connected to the inlet via passages 60, 65 in the valve body and a groove between the lands 54, 55 of the core. The piston 25 is thus raised and liquid flows from the top of the piston through pipe 22 to valve 1 and then via passages 66, port 81, bore 50, passage 59 to outlet port 12 and thence to valve 1a. By moving the core to the right the motor can be moved in the opposite direction. The valve 1a is similarly operated and both motors may be operated simultaneously. The ends 43, 43a pass between a pair of oil seals 44 separated by a spacer 45 in line with an oil drain 46 for draining any oil which escapes past the inner seal.
