Title: Method of transmitting television images by wireless
IPC: H04N5/04
Filed: 1934-03-05
Abstract: 436,142. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. March 5, 1934, No. 6897. Convention date, March 6, 1933. Drawings to Specification. [Classes 40 (iii) and 40 (v)] Both the light-intensity potentials and the scanning-potentials are transmitted from the transmitter. The picture signals and the deflecting-potentials for a cathode-ray receiver are transmitted on independent ultra-short waves, which are so close as to be similarly affected by atmospherics and fading. A separate receiver is used for each wave and that for the deflecting-potentials has fading compensation which also controls the receiver of the picture signals. The receiver for the saw-tooth scanning-potentials has fixed tuning, for example a quartz-controlled heterodyne receiver. A single transmitter of deflecting potentials is used in conjunction with a plurality of television transmitters in a single zone. The line-control potential modulates an intermediate carrier wave before modulating the ultra-short carrier wave together with the image-change potential. In addition, synchronizing signals may be transmitted over telephone cables to synchronize distant receivers.

Title: Improvements in gauges, relays and like devices responsive to gas pressure
IPC: G01L21/12
Filed: 1937-03-09
Abstract: 486,156. Thermionic relay circuits. DODDS, J. M., SYKES, C., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 9, 1937, No. 6931. [Class 40 (v)] A Pirani gauge is arranged to control a grid - controlled valve, such as that sold under the Registered Trade Mark " Thyratron " so that an alarm or indication is given or a control is affected when a pressure rises above or falls below a predetermined amount. The resistance element 10 of the gauge is connected as shown to control the grid bias on the " Thyratron " 1 which is supplied from an alternating current source through transformer 3, 4. The element 10 is connected in series with a fixed or variable resistance 19 across a portion of the transformer secondary 3, the value of the resistance determining the pressure at which relay 14 in the valve anode circuit is operated. If the resistance 19 comprises a Pirani gauge sealed off at a gas pressure equal to that at which the relay system is to operate variations in the supply do not affect the response of the unit. Resistance 20 enables compensation to be made for differences between the two gauges. With the arrangement indicated, the relay is operated at a pressure rising above a predetermined amount, but if the devices 10, 19 are changed over the relay will respond when the pressure falls below the predetermined value. Specification 417,621, [Group XIX], is referred to.

[Class 59] [Also in Groups III and V] To facilitate grinding, a pine wood resin subtantially insoluble in aliphatic hydrocarbons is added to the cement clinkers or to the raw materials to be ground before they go to the kiln. The amount of resin added may be, by weight;' 0.01 per cent. to 0.05 per cent. of the total charge to the mill. The resin is added in a finely divided condition. The resin may be obtained commercially under the Registered Trade Mark "Vinsol," or may be obtained as follows: Pine wood. which may have been steamed to remove volatile constituents, is extracted with benzene or toluene, the extract is freed of volatiles, and the residue, comprising rosin and the resin used in the invention, is extracted with an aliphatic petroleum hydrocarbon, e.g. gasoline. The gasoline dissolves out the rosin and leaves the resin. Instead of gasoline, furfural may be added to the benzene &c. extract, whereupon two layers form, the upper of which contains the resin which is recovered by evaporation of the furfural. The characteristics of this resin are described in the Specification. Specification 350,538 is referred to.
