Abstract: 496,498. Wringers. BACKHOUSE, F. (Koster, M.) May 26, 1937, No. 15403. [Class 138 (ii)] In a press-type wringer the goods to be wrung are placed within a chamber, the walls of which are defined, in part, by elastic sheeting which is expanded by the admission of fluid under pressure to the side remote from the goods. In the form shown in Fig. 1, fluid under pressure is admitted by a three-way tap 26 to the space between a rigid cylinder 11 and a cylindrical elastic sheet 12 secured thereto, thereby expanding the latter and compressing the goods housed within the elastic container, the expressed water passing through perforations in the cover 23 and base 15. The cover is secured by a bayonet joint arranged within a flanged annular channel 14 which secures the upper end of the elastic cylinder to the rigid cylinder and is provided with pipes 16 which are secured to the rigid frame 17 by nuts. The bayonet joint permits a limited upward movement of the cover to facilitate the discharge of the water to the channel 14. The lower end of the elastic cylinder is clamped to the rigid cylinder by the flanged base-plate 15, and the expressed water collects in a tray 18 having an outlet 19. In another form, the rigid cylinder may be built up from alternating perforated and imperforate segments, the elastic lining being provided over the imperforate portions only, thereby increasing the area of the water discharge portion. Shapes other than cylindrical may be used and a perforated tube may extend into the chamber for increasing the area of the water discharge means. In the form shown in Fig. 5, the goods are housed within the annular chamber defined by a rigid cylinder 30 and an elastic element 32 which is secured around a perforated member 33 through which fluid under pressure is admitted to act on the inner face of the elastic element.

Abstract: 235,875. British Thomson-Houston Co., Ltd., (Assignees of St. Clair, B. W.). June 20, 1924, [Convention date]. Tell-tale apparatus.-In a system for indicating at a distance the position of a member such as the pointer of a physical instrument, the receiver comprises a frequency meter connected to lines 12 which are supplied bv an oscillation generator 11. The frequency of the generator 11 is varied in accordance with the position of the pointer of an instrument 10, e.g. a wattmeter, by the movable vane 15 of a condenser 15, 16. The receiver is of the type described in Specification 628/12, [Class 37, Electricity, Measuring &c.], and comprises stationary coils 25, 26 disposed at right angles to each other and influencing an armature 27 which carries a pointer 28. The coils are arranged in parallel circuits and condensers 30, 31 are connected in series with the coils for tuning the circuits to frequencies which approximately correspond to the zero and maximum reading of the instrument 10. When the transmitter occupies either of its extreme positions, current flows through the corresponding tuned circuit and the pointer assumes the repeating position under the influence of the magnetic field of the coil 25 or 26. For intermediate positions, the current divides proportionately between both tuned circuits according to the frequency. The current at the receiver may be amplified by an amplifier 33. The mutual attraction between the condenser plates may be compensated by adjusting the usual control spring of the instrument, or the scale of the instrument may be calibrated with the condenser in its operative condition. The shape of the condenser plates is so chosen that the variation in frequency is proportional to the deflection.

Filed: 1967-04-05
Abstract: 1,148,245. Automatic phase control systems. BROWN, BOVERI & CO. Ltd. 5 April, 1967 [7 April, 1966], No. 15548/67. Heading H3A. The output of a divider 3 fed from a clock pulse generator 1 is synchronized with incoming binary data on line 12 by adding or deleting a pulse from the divider in accordance with the sense of the phase error. Outputs (B, C, D, Fig. 2, not shown) from the last three stages of the counter are combined in logic circuit 8 to develop pulses (a and b, Fig. 2) which overlap at the instant when an input pulse should arrive. These pulses on lines 9 and 10 condition a bi-stable 11 for operation by a pulse from unit 13; a monostable 18 is conditioned by a pulse from unit 13 and triggered into its unstable state by a pulse on line 19 from the second stage of counter 3, and according to the state of bistable 11 causes a pulse to be added or deleted from the gate circuit 2. Unit 13 is a pulse delaying and shaping unit comprising a monostable 14 set by 1-0 transitions of input signals; the output of monostable 14 sets a bistable 15 which is re-set by 1-0 transitions of the inverted input signals (on the un-numbered input line). After a delay of half a bit width the monostable 14 re-sets and passes a pulse to bistable 11 and to gate 16 which provides an output to unit 18 unless the initial 1-0 transition is followed by the reverse transition within half a bit width.

Title: Improvements in methods of obtaining hormones
Filed: 1933-05-31
Abstract: A hormone having the action of the anterior pituitary hormone is concentrated from solutions by forming in the solution a precipitate of a water-insoluble adsorbing substance, separating the precipitate, dissolving the adsorbent by a solvent which does not dissolve the hormone and extracting the residue by a solvent for the hormone.  In preparing the hormone from urine this material is acidified with acetic acid, clarified, and acetone saturated with benzoic acid is added, the precipitated benzoic acid is filtered off and dissolved in acetone, the remaining precipitate being filtered off, washed and extracted with water. The crude extract is purified by repetition of the above procedure and finally by fractional precipitation with acetone, the concentration of which is raised to about 50-60 per cent.  Still further purification is effected by precipitation at the isoelectric point in the presence of an organic liquid such as acetone.  In an example, a small quantity of a buffer salt such as brucine is added to an aqueous solution of the hormone made alkaline with ammonia, acetone acidified with acetic acid being then added in small quantities.  Other suitable adsorbents for use in the process are cinnamic, naphthoic, adipic, and stearic acids. Alcohol and ether may be used in place of acetone.
