Title: Geometrical and trigonometrical measuring instrument - has fixed and moving arms carrying measuring scales and connected by hinge pin
IPC: B43L7/12
Filed: 1976-03-03
Abstract: A geometrical trigonometrical measuring instrument for tracing arcs of circles, measuring radii etc., has a moving arm (1) and a fixed arm (2) joined by a hinge pin (5) which forms the axis of rotation. A slot (11) fitted with a scable has a guide mark for reading anles. The two adjacent edges carry scales (14, 15) and the moving arm carries a cursor (16). Attached to the outer end of the moving arm by a hinge pin (19) is another arm (17) with a further scale along it. This arm can cross the fixed arm, so that measurements can be read where the scales intersect. A simpler instrument does not have the further arm (17).

Title: Pushbutton switch for battery operated watch - has movable switch contact acting as stop for pushbutton
IPC: G04B37/10
Filed: 1976-03-16
Abstract: The push-bottom switch (3) for a battery operated watch has the push-bottom stem (9) located by a radial slot (2) in a frame ring (1) forming the sides of the watch case.

Title: Purifying a nickel matte by oxidn. - to remove e.g. iron, cobalt and lead which have a higher oxygen affinity than nickel
IPC: C22B23/02
Filed: 1976-04-15
Abstract: The impure Ni matte is selectively oxidised to transform the impurity into a metal oxide. The matte is then contacted with a mixt. of slag contg. an alkali metal oxide, SiO2 and B2O3 with or without Al2O3, an oxide of an alkaline earth metal or these two types of oxide, at 650-1350 degrees C. The metal oxide is dissolved in the slag mixt. and the Ni matte is removed from contact with the slag. By reducing the slag mixt. metal oxide is converted to a metal impurity which can be sepd. The impurity and slag mixt. are then removed. The reaction temp. is low and the process is less corrosive towards the refractories. The impurities which are removed include Fe and Co. Surprisingly a certain amt. of Pb is also removed.

Title: 2,4-Di:amino pyrimidine sodium sulphonate cpds. - useful as water soluble antibacterials and sulphonamide potentiators
IPC: C07H17/02
Filed: 1976-07-12
Abstract: Sodium sulphonate derivs. of 2,4-diamino pyrimidines (I) are new. (where R1-R4 = H, halogen, alkyl, alkoxy or benzyloxy and are the same or different; R = the residue of an aldehyde R-CHO which may be a straight or branched aliphatic aldehyde of 1-4C or R is a residue Z-CH=CH- where Z = H, straight or branched satd. alkyl, aromatic ring or a heterocyclic ring, or R is a radical HO-CH2-(CHOH)n- where n is 3 or 4).

The presence of the sodium sulphonate gps. on (I) increases the water solubility without loss of bacterial action, enabling neutral injectable aq. solns. of sulphonamides and its potentiator to be prepd. A typical cpd. is the sodium N2, N4-bis-ethane sulphonate of 2,4-diamino-5-(3',4',5'-trimethoxybenzyl)pyrimidine. This was prepd. by mixing 145g. trimethoprim with 350ml. water at 50 degrees C and adding 163g. acetaldehyde bisulphite addn. cpd. in 400ml. water.

Title: Horizontal cylindrical rotary drum for soaking potatoes etc. - in treatment liq. of controlled concn. for controlled duration
IPC: A23N15/06
Filed: 1976-07-30
Abstract: The machine treats vegetables, fruit etc. by soaking them in a bath of liq. through which they are continuously conveyed. The prod. is fed into a horizontal, cylindrical, rotary drum which has a perforated shell. The lower part of the shell is immersed in liq. in a treatment bath. Inside the drum, a coaxial, helical scroll conveys the prod. through the liq. as the drum rotates. At the discharge end of the drum, radial paddles lift and drain prod. which is delivered for packing. The depth to which the drum is immersed in the liq. is approximately equal to the effective radial width of the conveying scroll. Below the drum, a make-up tank is pref. installed to contain concentrated treatment liq. which is added continuously to the bath to keep up liq. strength in operation. The make-up liq. is transferred by a bucket elevator driven from the rotating drum. Drive to the rotary drum is pref. via belt loops in which the ends of the drum are suspended. The treatment is usually to protect the prod. from disease, rotting, pests, etc. during storage prior to use as seed or food. Fully mechanised soaking is of controlled duration, depth and concn. excellent penetration of soiled vegetables, and no damage to prod. are other advantages.

Title: Flexible detachable pipe coupling - has component with concave face pressed by nut against flexible flange
Inventor: WAKEFIELD FANCHER B
IPC: F16L27/047
Filed: 1976-09-01
Abstract: The flexible and detachable pipe coupling is for a medium at high pressure, where the two pipes do not need to be axially aligned. A seat component (2) fits on one of the pipes to form an extension of it and has at its free end an internal concave sealing face (7), bearing against a mating convex face (8) on the other half. An internally-screwed union nut fits over the component, and has an internal concave face (5) complementary to that on the component, screwing onto the other half of the coupling. A flexible flange (12) on the coupling forms a seal against the concave face of the component when the nut is tightened up, being distorted in the process and thus pre-stressed, allowing angular deviation between the two pipes.
