A manually-operable ball valve 2, which is disposed between adjacent pipe couplings 23, comprises an annular housing 21 and disposed within it a ball 3, sealing of the ball with respect to the housing and couplings being effected by means of elastic stainless steel seals 28. Rotation of the ball is effected by means of a handle 8 acting through a shaft 1, the shaft having a lug 16 engageable with a mating recess in the ball, a conical portion 15 adapted to engage a correspondingly shaped seating 19 in the body, and a spherical portion 13 adapted to be engaged by a correspondingly shaped recess 5 in an annular tightening plate 4, the plate being fixed to the body by four screws 6 and serving to securely hold the shaft in position and the conical portion 15 in contact with its seating. Disposed on the shaft, and in between the conical and spherical portions 15, 13 respectively, is a flat rectangular collar 14, each wing 17 of which has a notch 32 formed in each of its longitudinal edges, which notches serve, by engagement with the screws 6, to limit the degree of rotation of the ball (Fig. 3, not shown).

Title: Window Furniture
Inventor: DONKIN JOHN
IPC: E05C17/18
Filed: 1965-07-16
Abstract: 1,155,833. Window stays and fasteners. ARCHIBALD KENRICK & SONS Ltd. 22 June, 1966 [16 July, 1965; 2 Aug., 1965; 3 Dec., 1965], Nos. 30254/65; 32920/65 and 51359/65. Headings E2A and E2F. A window fastener or stay is detachably pivoted on a mounting member by a snapfitting resilient member. The mounting member 10 consists of a plate or bracket having countersunk holes 12 for attachment to a casement frame, and a projecting pin 13 with a groove 13a. A lever member 11 for engagement in use with a suitable projection on the fixed frame of the window, has a terminal boss 14 bored to encircle the pin. The bore is countersunk at one end and counterbored at the other to give it a frusto-conical mouth 14b and a shoulder 14a. A resilient synthetic resin bush having flanks 17, an annular flange 18, an internal rib 20 and three longitudinal slits 19, is compressed and inserted into the bore, then released so that the flanks and flange engage respectively with the mouth 14b and the shoulder 14a, to retain the bush in the bore. The bush is then pushed over the pin 13 so that the rib 20 resiliently snap-fits into the groove 13a, to retain and provide a bearing for the lever. In an alternative embodiment, (Fig. 3), the resilient member is in the form of a cap retained in a recess in the upper part of the bore by peening over the adjacent walls thereof. The mouth of the cap has an internal rib which snap-fits into a groove near the end of the pin. In this case the bearing surface is provided by the wall of the bore, the resilient member serving as a retainer only. A window stay is preferably mounted via an intermediate connecting member, of which the one end is detachably pivoted to the frame mounting member as above and the other is permanently hinged to the stay. The permanent hinge is a knuckle joint type, a blade on the connecting member being pivotally mounted on a pin between bifurcations of the end portion of the stay member, providing hinge whose axis is perpendicular to that of the detachable pivot. The blade has an extension or shoulders co-acting with the stay to provide a supporting stop. The stay, fastener or connecting member may be detached from the pin by prising off with a suitable tool inserted between the boss and mounting member, the resilient member remaining in position in the boss.

Abstract: 1315614 Amplitude limiters; colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Nov 1971 [10 Nov 1970] 51535/71 Headings H3T and H4F In an amplitude limiter of the type in which a limiting element, e.g. transistor 29 or a diode 7, Fig. 3 (not shown), is connected across the output of an amplifier 18 and in which curvature of the limiting characteristic is reduced by applying an oppositely phased signal from an amplifier 19 to the other terminal of the limiting element, the curvature is further reduced by making the opposite phased signal larger than the erect signal and connecting resistance 16 in series with the element. The purpose of the resistance is to prevent a dip in the limiting characteristic. When a transistor is used as the limiting element a signal or an amplified signal can be applied via a potentiometer to the base, a diode 30 being included to provide temperature compensation. Where a particular frequency is to be excluded from the limitation, for example, the chrominance sub-carrier component of a video signal, a curcuit resonant at the frequency can be included in the emitter circuit of the limiter transistor 29.

Title: Shapoo compositions containing styrene maleic anhydride copolymers
IPC: C11D3/37
Filed: 1970-10-30
Abstract: 1333786 Styrene-maleic anhydride copolymer salts in rug shampoo compositions ATLANTIC RICHFIELD CO 30 Oct 1970 [17 Nov 1969] 51830/70 Heading C3P [Also in Division C5] A rug shampoo composition, suitable for cleaning rugs, carpets and upholstery, comprises a detergent and an additive which is a watersoluble salt of a styrene-maleic anhydride copolymer or partial ester thereof which is present in an amount of from 5 to 95% by weight of the total solids content of the composition and is of a nature such that the dry residue of the shampoo is embrittled. The weight ratio of copolymer to detergent can vary from 1 : 19 to 19 : 1 and is preferably between 1 : 1 and 1 : 7. The compositions can also contain a foam builder or stabilizer, generally used in an amount of 5-75% by weight, preferably 10-35%, of the total solids. The composition is generally formulated as a concentrated aqueous solution containing 30-95% by weight of water and used as a more dilute solution containing 0À5- 3%, preferably 1%, by weight of solids. In addition to water the compositions may include minor amounts of water-soluble alcohols, and silicates or other alkaline builders, e.g. phosphates, grease or oil solvents, sequestrants, viscosity builders and optical brighteners. The copolymers are described for example in U.S. Patent No. 3,388,106. They have about 1 to 4 moles of styrene per mole of maleic anhydride and molecular weights of 600 to 50,000, preferred respective amounts being 1 to 3 moles per mole and 700-5000. Suitable copolymer salts are the metal, ammonia and amine salts, particularly the ammonium salts, which are prepared by heating aqueous solutions of the copolymers with NH 4 OH. Preferred partial esters are the C 1-18  alkanol, e.g. n-propyl, and cycloalkanol, e.g. cyclohexyl, half-esters. Preferred detergents are the water-soluble ammonia, amine and metal salts of fatty alkyl sulphates or alkyl ethoxylated sulphates, N- acyl-sarcosines and N-acyl-sarcosinates, e.g. sodium and magnesium lauryl sulphates and sodium lauroyl sarcosinate. Preferred foam builders are alkanolamides, alkylamides, sulphosuccinates and amphoteric cycloimidines. In examples the effectiveness of the present compositions in the cleansing of carpets and, particularly, the effect of this cleansing on the resoiling characteristics of the carpets are compared with the results obtained using similar compositions that do not contain the copolymer salts. The present compositions leave very birttle, non-tacky residues which are usually easily removed when dry and generally make little, if any, contribution to resoiling, in marked contrast to the prior art compositions not containing the polymer salts.
