Abstract: 286,262. Electrical Research Products, Inc., (Assignees of Ives, H. E.). March 2, 1927, [Convention date]. Television.-In a two-way television system, which may be combined with a telephone system and mav work through an exchange, the subscriber is irradiated with invisible radiation in order that he may not be dazzled, and light-sensitive cells selective to such radiation are employed at the transmitters. Fig. 1 shows a subscriber 9 speaking into a telephone 10 and irradiated by an exploring beam of ultra-violet and infra-red radiation reaching him from a source 11 through a screen 13, (which filters out most of the visible, including the yellow and green, part of the spectrum), a scanning disc 21, an optical system 15, 16, 17, and one half of an aperture 25. The radiation is diffusely reflected from the face of the subscriber 9, through further filterscreens 32, 32 on to pairs or groups of cells 31, 31, of which each pair may comprise one photoelectric cell, sensitive to ultra-violet radiation, and one thalo-sulphide cell, sensitive to infra-red radiation. The relative effects of the two kinds of cell can be adjusted so as to give the right tone value to the picture. The output of the cells, after amplification at A, is sent to line and through an exchange 100 to another subscriber's apparatus. Incoming television signals are applied to the neon lamp 50, and the resulting variable illumination is synthetized by the scanning disc 21 and optical system 37, 38, 39, so as to be visible through the remaining half of the aperture 25. The scanning disc 21 is provided with two diametrically opposite spirals of holes, so that received and transmitted signals pass simultaneously through opposite holes.

Rulers; dividing-instruments.-A parallel and section-lining ruler comprises a framework and a movable member which can be measurably displaced in order to determine the distance between successive lines and to facilitate ruling a series of lines at equal distances apart. As shown in Figs. 1, 4, and 5, the frame a has a triangular aperture in which is disposed the wedge-shaped movable member b. The lower edge of the aperture has a scale h coacting with an index b<2> on the member b to indicate the distance between successive lines. The frame also carries a pivoted arm c having a stop e passing through a groove f, an index e<1> on the arm coacting with graduations g. The required adjustment may be obtained either by setting the index b<2> or by setting the arm c and then moving the member b until it abuts against the stop. In the modification shown in Fig. 6, the index b<2> is supplemented by a slidable index b<3> which can be displaced by a, rotatable cam k on the member b; a scale k<1> is marked on the member b around the cam. This ruler may be used to divide a given length into any desired number of equal parts. the arrangement being such that the index b' is displaced by turning the cam so as to give the unit in which the measurement is made, the index being then set opposite a whole number on the scale h. The scale h is replaceable and is held by a spring h<1>. This form of ruler may also be used for columnar shading in which the distance between successive lines is first regularly increased up to a maximum and then regularly decreased. In a further modification the pivoted arm c is replaced by a slidable member on the part b adapted to abut against the part m of the frame.

Abstract: 547,333. Aliphatic per-acids. BRITISH CELANESE, Ltd. Feb. 21, 1941, No. 2371. Convention date, Feb. 21, 1940. Drawings to Specification. [Class 2 (iii)] Aliphatic per-acids are produced by passing the vapour of the corresponding aldehyde together with a quantity of oxygen insufficient to oxidize more than about 30 per cent. of the aldehyde through a heated reaction zone. The reaction temperature may be 350-400‹F. and the mixture may be preheated to 200‹F. or more ; the linear velocity of the stream may be 30-300 ft./sec. and the reaction time 0.1-1 second. Oxidation catalysts are unnecessary. The process is described with reference to the production of peracetic acid from acetaldehyde. In an example, a part of the reaction product is recycled and the remainder after the addition of benzene vapour is led to a fractionating column maintained at an absolute pressure of 3 pounds per sq. inch and at such temperature that an azeotropic mixture of benzene and acetic acid together with excess acetaldehyde and inert constituents passes off while the peracetic acid is withdrawn at the bottom of the column. Propionaldehyde butyraldehyde, valeric, caproic and other higher aldehydes may be oxidized similarly.

Filed: 1970-01-19
Abstract: 1282648 Hydrotherapeutic baths AMERICAN STANDARD Inc 19 Jan 1970 [22 Jan 1969] 2455/70 Heading A4N [Also in Division B1] A nozzle assembly has a water inlet pipe 80 which can be inserted in the drain 12 of a bath to communicate with a pump 14. The pump draws water from the bath through pipe 16 and pumps it to the nozzle inlet pipe through pipe 18 creating whirlpool action within the bath. The nozzle assembly may be removed from the bath, which is then free from internal obstructions. The water discharges through outlet nozzle 20, and draws in air through a pipe 22. A butterfly valve 26 and a rotary valve 32 control the water and air-flows respectively. Spacing ribs below the body of the nozzle assembly ensure clearance around the pipe 80 to allow water to drain from the bath into the pipe 16 to be recirculated. The inlet pipe 80 depends into a connector beneath the bath and engages a seal in a partition which separates the parts connected to the pipes 16, 18. The partition however has a small drain opening (60), Fig. 8 (not shown) to prevent stale water remaining after the bath is emptied. The bath is emptied by operating a handle or knob 38 to lift a plug in the waste pipe 43. The pump is located above the bottom of the bath (but outside it), and has a vent pipe 34, so that it is primed as the bath is filled. The vent is connected to the overflow pipe 36. The operation of the pump may be controlled by a timer.
