In an apparatus for maintaining an ideal temperature distribution in a stream of molten glass, the electrical resistance or power dissipated between a pair of electrodes 13a, 13b, Fig. 1 (Proc.), and an outlet nozzle 11, the wall of which comprises an electrode 12, are observed and utilized in the control circuits shown. The electrode 13b is movable and the average electric resistance between the electrode pairs 13a and 12, and 13b and 12 is measured by means of relay A1 and utilized to operate a series of relays which in turn control reversible servomotors M1a, M1b in the same directions to modify the current flowing between the electrode pairs by varying the booster transformers T4a, T4b. Alternatively, manual control of relative resistance is obtained by means of switch S1 which operates the motors M1a, M1b in opposite directions, the switch being operated in accordance with an operator's reaction to the appearance of the gob as it issues out of outlet 11. In a modification a furnace has two adjacent outlet nozzles 11<SP>1</SP> and 11<SP>2</SP>, Fig. 7, with inner ring electrodes 12<SP>1</SP> and 12<SP>2</SP> and outer electrodes 13a, 13b and 13c, and the supply circuit may be as shown in the Provisional drawing except that if desired, individual manual or automatic control may be provided for the motors M1a and M1b so as to permit the voltage between 13a and 12<SP>1</SP> to be raised or lowered without changing that between electrode 13b and its companion electrode 12<SP>2</SP> and vice versa.

Title: An improved windscreen wiper for use on vehicles
IPC: B60S1/44
Filed: 1930-02-13
Abstract: 342,906. Windscreen wipers. HURD, G., 12, Rhodes Terrace, Beddington Grove, Wallington, Surrey. Feb. 13, 1930, No. 4855. [Class 138 (i).] A windscreen wiper u is driven directly by a screw propeller s mounted on a shaft p supported by ball-shaped members q, engaging a tube r carried by an arm b on the screen, or the shaft may itself pass through the screen. Due to the absence of gearing and friction, the propeller and wiper arms rotate so rapidly as to be practically invisible. Snow and moisture are thrown outwards by the centrifugal action. The complete apparatus is clamped to the upper edge of the windscreen a. The curved tube b is screw-threaded to receive a nut c, two clamping arms d, e, and thin metal washers f. The clamping member e can be rotated to clamp the plates f together. A handle h can be fixed by a set-screw i to act as a lock-nut for the member e. Within the tube b is a flexible shaft k rotatable by a handle l. At its lower end, the flexible shaft carries a screw thread m engaging the outlet of the tube b so that rotation of the shaft will bring a bevel wheel n in and out of engagement with a bevel wheel o on the shaft p to rotate the wiper. The arms t of the wiper are bent to present a convex surface in the direction of rotation to assist in throwing off rain &c. When the screw commences to rotate, the air pressure moves the shaft p slightly backwards till the strip u is in contact with the glass. The tube r is fixed in a split lug v extending on a plate w adjustable on a plate y attached to the tube b. A spring j causes the handle l when released to move backwards taking with it the flexible shaft k and disengaging the bevel wheel n from the wheel o. Movement of the handle h in an arc rotates the curved tube b and wipes the screen rapidly. A long strip of the screen can be wiped by sliding the apparatus along the top of the windscreen. If desired, the parts d, e, f may be replaced by a bearing tube passed through an aperture in the windscreen.

Filed: 1932-02-22
Abstract: Yeast adenylic acid (adenosine triphosphoric acid) is converted into muscle adenylic acid (an adenosine phosphoric acid) by hydrolysis at a temperature of 10-50 DEG  C.  The starting material or crude extract containing it is treated with a hydrolysing agent such as barium hydroxide, caustic soda or mineral acid solution at ordinary or slightly raised temperature, a precipitant then added and the product separated from the precipitate.  The adenosine phosphoric acid thus obtained is useful in the therapy of the circulation of the blood.  Examples are given.  The starting material may be prepared by (1) extracting yeast in the cold with trichloracetic acid, mixing with mercury acetate under feebly alkaline conditions, decomposing with hydrogen sulphide and precipitating the adenosine triphosphoric acid as its calcium salt using calcium chloride and alcohol; (2) treating with water plasmolysates obtained at a low temperature from yeast, eliminating the undissolved constituents, and if desired treating the solution with absorbents, e.g. bentonite, and precipitating with organic solvents, e.g. methyl alcohol, the solution remaining after removing the absorbent; (3) extracting yeast with trichloracetic acid before or after plasmolysis, giving a crude material; (4) plasmolysing yeast with ethyl acetate at a temperature below 15 DEG  C. and introducing into boiling water.
