Title: Improvements in wall and ceiling construction
IPC: E04F13/08
Filed: 1931-03-18
Abstract: 373,699. Walls ; ceilings. WALPER, C. O., 26008, Pembrook Road, Huntington Woods, Michigan, U.S.A. March 18, 1931, No. 8349.

Title: Apparatus for indicating measured values
IPC: G01D7/00
Filed: 1970-02-20
Abstract: 1,260,791. Indicators. V.D.O. TACHOMETER WERKE ADOLF SCHINDLING G.m.b.H. 20 Feb., 1970 [22 Feb., 1969], No. 8359/70. Heading G4H. Apparatus for indicating measured values comprises a plurality of luminous cells 24, Fig. 2, a source of alternating voltage, 25, a plurality of selectively operable electronic switches for connecting the cells to the source of alternating voltage, each switch including a rectifier bridge, one pair of opposite points of which are connected to the source 25 and the luminous cell 24 in series, a switching transistor 26 being connected across the other pair of opposite points. A thyristor may replace transistor 26. A measured value to be displayed is first converted to a train of pulses which is counted in a two-decade counter to obtain an equivalent decimal number. In the form described the display is in the form of a ribbon of say 50 luminous cells which are all illuminated up to the point indicating the value to be displayed. The count in the units decade of the counter is recorded to markthe corresponding one of ten leads and all leads of lower value. The tens decade has only three operative stages and there are only 5 output leads from the decoder, representing values 10, 20, 30, 40 and 50. The ten units and five tens leads control gates supplying a high frequency signal to the switching bridges via transformers 27. The switches, when selected, therefore open and close at high frequency but the display appears continuous because of the capacitance of the luminous cells. The luminous cells are arranged in groups often, C00-C09, C10-C19 etc., Fig. 5. Switch S1 controls cell C01 in the first group and, through a half-bridge 37, to corresponding cells in all the other groups. The counter-electrode 34 of the first group C00-C09 is permanently connected to the source. The counter-electrodes of the other groups are selected by the output of the tens decoder. If a number 24 is present in the counter, therefore, the units digit 4 causes the four switches S1-S4 to illuminate cells C01-C04. The tens digit operates switches S10 and S20 so that the corresponding four cells in these groups also light. To fill in the gaps between 4 and 10 and 14 and 20 further switches S10<SP>1</SP>, S20<SP>1</SP> etc. are arranged to operate with switches S10, S20 etc. The switch S10<SP>1</SP> is connected by diode pairs 44, 45 to all the cells of the first group so that when the counter number is 10 or above all the cells of the first decade light, and so on. By this means the cells are lit in a ribbon extending to the position corresponding to the number displayed. The switches S10, S10<SP>1</SP> are connected to operate together by being connected each to a separate secondary winding of the control transformer. By changing the decoders the circuit can be arranged so that only the cell corresponding to the measured value lights.

Abstract: 1398509 Cyclopentadienes STAMICARBON BV 25 Feb 1974 [1 March 1973] 8443/74 Heading C5E Cyclopentadienes are prepared by the vapour phase cracking of dicyclopentadienes, in the absence of any liquid dicyclopentadiene the maximum amount of molecular oxygen present being 10 ppm. The absence of liquid dicyclopentadiene may be attained by ensuring that the partial pressure of the dicyclopentadiene is less than, preferably 70-90% of, the vapour pressure of dicyclopentadiene at the reaction temperature. The reaction may be carried out at 170-400 C., in the presence of an inert gaseous diluent, e.g. deoxygenated N 2 , at a total pressure of 0À5-2 atmospheres. In the example dicyclopentadiene vapour and N2 were passed through a tubular reactor containing iron curls.
