IPC: F16L37/23
Filed: 1959-02-05
Abstract: 865,002. Pipe couplings. LUCAS (INDUSTRIES), J. Ltd. Jan. 25, 1960 [Feb. 5, 1959], No. 4066/59. Class 99(1). A coupling comprises in combination complementary tubular parts 4, 5, the part 4 having an end portion 4a adapted to fit within the adjacent end 5a of the part 5, spring-loaded valve closure members 11, 12, co-operating with seatings 9, 10 formed in the coupling parts and adapted to be removed from their seatings automatically on interengagement of the parts, a sealing member 8 located between the overlapping ends 4a, 5a when the coupling parts are engaged, a guide 21 fixed relative to the part 4, a spring-loaded sleeve 22 axially slidable within the guide, a second spring-loaded sleeve 25 surrounding the guide and axially movable relative thereto, and radially movable locking members 24 disposed within holes in the sleeve 22, those members being adapted to coact with an external shoulder 28 on the part 5 and an internal projection 27 on the sleeve 25 to retain the parts in engagement. When engaging the coupling parts the part 5a contacts the balls 24 to move the sleeve 22 inwardly against the spring 23 whereby the balls are out of register with the cam ring 27 to allow the coupling parts to be engaged to the fullest extent. The shoulder 28 passes through the ring 27 and the sleeve 22 is moved to engage the balls between the ring and the part 5 and behind the shoulder. The coupling parts are disengaged by imparting relative axial movement between the part 4 and sleeve 25. In a modification, the sleeve 25 is connected to a fixed part and constitutes the means for mounting the part 4, and a pull exerted on the part 5 causes the coupling parts to move axially relative to the sleeve 25 until the part 5 is released and withdrawn.

Abstract: 852,292. Sceew-cutting. GUIDO, J. Feb. 6, 1957 [Feb. 22, 1956], No. 4128/57. Class 83 (3). Mechanism for cutting a screw-thread on a non-rotating workpiece comprises a rotatable and axially-movable chaser and a concentricallymounted cam-disc for moving the tool, which is rotated at a speed different from that of the tool. A thread-cutting tool 7 is carried by a shaft 1 rotated by a belt pulley 5. The toolholding part may be pivoted to feed the tool, or may be arranged in an inclined guide for this purpose. Axial movement for the screwcutting is obtained from a cam 14 integral with a gear 13 and coaxial with the shaft 1, but separately supported. A follower 17 secured to the shaft is maintained against the cam by a spring 18. The cam is rotated relative to the shaft 1 by a gear 10, fixed thereto, driving a gear 12a, 12b on a countershaft 11. A further gear 15a, 15b on the countershaft, having a one-tooth difference from the wheel 12a, 12b, drives the cam-gear 13. The wheels 12a, 12b and 15a, 15b are in two parts, with springs for taking up backlash.

Title: Purified extracts of gleditsia species and compositions thereof
IPC: A61K31/10
Filed: 1966-01-31
Abstract: Aqueous extracts of the seeds of Gleditsia triacanthos (Honey locust tree), containing from 0.1 to 5% by weight of polyosides derived from the gum present in the seeds, are purified by filtration in the presence of a filter aid.  The filter aid may be any inert finely divided solid, preferably the Kieselguhr material "Clarsil" (Registered Trade Mark).  The resulting solution, which has a polyose content of 99 to 99.5% by weight of the total solids content is useful, by reason of its viscosity, in pharmaceutical and cosmetological compositions, optionally after concentration to a gel having a polyoside concentration of 4 to 5% by weight. Pharmaceutical compositions comprise the said purified solution or concentrated gel as an excipient, together with one or more active ingredients.  Such compositions include an orally administrable antacid "bismuth milk" of the purified extract together with either bismuth subnitrate or a mixture of bismuth silicate and aluminium silicate suspended therein; topical compositions of the gel with prednisolone, phenylbutazone, or dimethylsulphoxide; and moisturizing creams of oily or fatty materials together with the purified solution or gel.

Abstract: 401,650. Enamelling ; alloys. KREIDL, 1., 5, Sebastian Kohlgasse, Vienna. Feb. 12, 1932, No. 4224. Convention date, Feb. 12, 1931. [Class 56.] Enamelled sheet iron, or vessels and other articles made therefrom are produced by applying the enamel to an alloy of iron with at least one of the metals whose oxides cause adhesion, the quantity of such metals being sufficient to cause adhesion. Cobalt and nickel are the most effective, but a few other metals such as manganese, copper, molybdenum, and tungsten may be employed, preferably only in conjunction with cobalt or nickel. An iron alloy containing 1 to 2% of nickel is suitable while, in the case of manganese, at least 2% is essential. Opaque, especially white opaque enamels can be obtained by a single coating without employing a base enamel, whether solid clouding agents, such as oxides of tin or zirconium, or gas clouding agents are used. The Specification as open to inspection under Sect. 91 refers to the use of alloys containing less than 1% of cobalt. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to arrangements for demodulating electric carrier oscillations that are modulated by television signals
Inventor: HARLING DENIS WILLIAM
IPC: H04N5/455
Filed: 1958-02-14
Abstract: 840,485. Radio receiving systems; homodyne receivers. GENERAL ELECTRIC CO. Ltd. Feb. 13, 1959 [Feb. 14, 1958], No. 4877/58. Class 40 (5). In an arrangement for demodulating a carrier signal which is amplitude-modulated by television signals of the type in which the picture information 2, Fig. 1, and the synchronizing pulses 1, 4 lie on opposite sides of a given amplitude level 3, means are provided for preventing the demodulated signal from becoming inverted when the phase of the carrier wave is reversed for short periods owing to the modulation ratio being greater than unity. In one embodiment, Fig. 3, a local oscillator 14 has the same frequency as the carrier wave and is also arranged to have a given phase relationship with the carrier wave under normal circumstances, but when the phase of the carrier is reversed, the polarity of connection of oscillator 14 is also reversed so that the demodulated signal maintains the correct polarity. The incoming modulated carrier signal is applied via terminal 11 and attenuator 12 to a demodulator 13 which is also fed by oscillator 14, the output signal being taken from point 15. Part of the incoming signal is applied to the control grid of pentode 19 and part of the output of oscillator 14 is applied to the control grid of pentode 22 so that the derived signal at point 24 is effectively the sum of the voltages applied to valves 19, 22. This derived signal is amplified and passed to diode 32 and peak rectifier circuit 33, the output voltage of which is developed across capacitor 34. When the output signal is of the correct polarity the output of circuit 33 is steady and valve 43 conducts, thereby operating relay A and preventing the operation of relays CO, B. If the local oscillations are phased for the output signal to be inverted the output of circuit 33 contains an alternating component at the frame repetition frequency which component is applied to valve 45. The output of valve 45 biases valve 43 so that relay A is not operated and contact a1 closes as shown. Relay CO operates to close contacts co1-co4, thereby reversing the polarity of oscillator 14, and, after a delay, causing relay B to operate. Relay is CO then released, and if relay A is still not operating the cycle is repeated until relay A operates. Alternatively relays CO, B may be omitted and relay A arranged to interrupt the control path to oscillator 14 which oscillator is thus allowed to free run until the correct phase relationship is obtained. Specifications 771,366 and 817,059 are referred to.
