Addition to 1,067,461. Heading CIA. Synthetic crystalline mordenite is prepared by heating the gel obtained in the manner described in the parent Specification at 100‹ to 250‹ C. and at or above 1 at. The pH of the mother liquors after crystallization is at least 7.5 and preferably 11-13. The crystallization period is more prolonged in this method compared to that of the parent Specification. In the region of 100‹ C. the use of equipment under pressure is avoided. Other alkali and alkaline earth metal mordenites can be prepared from the synthetic sodium mordenite by partial or complete exchange of the sodium ions. The sodium ions may also be exchanged for hydrogen ions or the ions of the metals nickel and cobalt.

A bellows is reinforced by foils extending unbroken across the creases of the folds axially from one end of the bellows to the other, the foils having greater flexibility on the lines of the creases than they have elsewhere. The bellows may be used for the protection of the slideways of reciprocating parts in machine tools, such as grinding-machines, or may be of the box type. A square section box type bellows of the " inverted folded " type is reinforced by foils 27, Fig. 4, stuck to the inside of the bellows material, and having transverse rows of perforations 28 along the lines of creasing of the bellows material. A bellows of the " all-round continuous folded " type is reinforced by foils 30, 31, Fig. 5, stuck to the inside of the bellows material and having grooves, corresponding to the lines of creasing of the bellows material, formed by thermal treatment or by milling, slotting or grinding. The facing edges of the foils are zig-zag to strengthen the flanks of the bellows folds right up to the salient crease at the edge. Instead of grooves, the foils may have perforations 35, Fig. 7. The bellows may be of hexagonal or octagonal cross-section. The foils may be of thermoplastic material, e.g. one based on polyvinyl chloride or a polyester. The foils may have venting holes 36, 37, Fig. 7, to hasten the drying of the adhesive used to secure them to the bellows material. The reinforcing foils may be bonded by spot welds, line welds or surface fusion to the bellows material which is then preferably of polyvinyl chloride incorporating reinforcing filaments or threads. In a modification, the reinforcing foils 30, 31, Fig. 9, have slits 38, 39 at those creases which form salient creases on the outside where the sides of the bellows meet. A wire is inserted to extend along the entire length of the slits and is secured by sticking or welding a tab 40 over the slits. In a further modification, a narrow strip of softer material is secured over the perforated creases from the inside of the bellows.

Abstract: 1524380 Charge transfer devices RCA CORPORATION 14 Nov 1975 [18 Nov 1974] 47077/75 Heading G4A [Also in Division H4] In a charge transfer system comprising an array of charge transfer elements arranged in P rows and Q columns, (the electrodes 28, 30 of the last row and five columns 60, 62, 64, 65, 67 being shown in Fig. 4) an N phase output register C includes electrodes 48a, 50a, 52a ... each aligned with one of the columns and every Nth electrode being controlled by the same phase control signal (as described N = 2 and the electrodes are connected alternately to control signals # C1 , # C2 ) so that 1/N of the stored data is transferred to the output register at a time, this data being transferred out by a switch 70 before the next 1/N of the stored data is read out. The apparatus may be used for reading out video information from a frame transfer CCD imager. In the embodiment of Fig. 4 first the data beneath electrode 46 in column 60, 64, 67 is transferred to beneath electrodes 48b, 52b, 54b. Then the data in columns 62, 65 is returned to beneath electrode G2, the data beneath electrodes 48b, 52b, 54b then being read out into register 72. Next the data in columns 62, 65 is stored beneath electrodes 50b, 53b and then a register C2 is clocked at twice the frequency to interleave the first read out data stored in register C1 with the data in the output register C. In the embodiment of Fig. 8 the output register is controlled by three phase control signals # C1 , # C2 , # C3 . Stored signals are successively propagated in electrodes 109, 110, 112, 114 and at phase control signal # C1  the signals stored in channels 100, 103, 106 spill into the well beneath electrodes 132, 138, 140, the rest of the signals being propagated back beneath electrode 112. Before the next phase control signal # C2  is applied, signal G7 goes high and then low so that signal stored beneath for example electrode 132 is transferred via electrode 116 to beneath electrode 142. Subsequently at phase control signals # C2 , # C3  the charge in the other channels is transferred and at phase control signal # C2  the signal stored beneath electrode 142 is transferred to beneath electrode 144. The system of Fig. 8 may be modified for control by conventional push clocks (i.e. overlapping clocks with slow fall times). The signals from the output register may be weighted to simulate a horizontal photosensing aperture of desired shape, e.g. a Gaussian distribution may be obtained.

Title: Improvements relating to electrodeposition of tin
Inventor: DEAKIN JOHN EDWARD
IPC: C25D3/32
Filed: 1965-11-09
Abstract: An acid tin electro-plating bath contains, in addition to a tin salt such as stannous sulphate, an aromatic amine in which two benzene nucleii are linked to each other through an alkylene, imino, carbonyl or sulphonyl group or through an oxygen or sulphur atom and there is at least one primary amino group as a nuclear substituent. Typically the bath concentration of the amine is from 0.02 to 0.04 gram mol per litre and the amine may contain as nuclear substituents fluorine, chlorine, or bromine or alkyl, alkoxy or hydroxy groups.  The bath may also contain phenol sulphonic acid and may be used at 35 to 60 DEG C. with a current density of 50 to 250 amps/sq.ft.  In an example a cylindrical steel is rotatably supported in a cylindrical cell between a pair of spaced discs on a spindle disposed on the cell axis, six tin anodes being symmetrically arranged inside the cell walls and baffles being provided to prevent rotation of the electrolyte. The tin-coated steel is subsequently dipped in phenol sulphonic acid, dried, and flow brightened by passing a heating current through it followed, immediately the tin starts to melt, by quenching in phenol sulphonic acid.

Abstract: 1,072,678. Fluid-pressure servomotor systems. AUTOMOTIVE PRODUCTS CO. Ltd. Nov. 23, 1964 [Dec. 2, 1963], No. 47475/63. Heading G3P. The pitch of helicopter blades is adjusted by a tubular member 55 movable axially by a servopiston 25 under the control of a piston valve 28 which is centred relatively to the servopiston by a spring 48 and acted upon by flyweights 38 mounted on the servopiston. The blades, which are rotated by jet motors at their tips, are urged by spring means (not shown) to their fine-pitch position and by fluid pressure in a chamber 26 acting downwardly on the servopiston to their coarse-pitch position. The assembly comprising the member 55, servopiston 25 and cylinder 12 containing the servopiston is rotatable in bearings 15, 16 in a fixed housing 11, and such rotation actuates a pump comprising radial bores 18 containing pistons 20 coacting with an eccentric ring 21 in the housing. The pump discharges to a chamber 35 having a relief valve 54 and a connection with ports 32 of the piston valve 28. Increase of speed causes downward movement of the piston valve against loading springs 43, 48 allowing pressure fluid to flow from the chamber 35 to the chamber 26, thus causing a downward movement of the servopiston to coarsen the pitch and follow up the movement of the piston valve. At the same time the compression of the spring 43 is increased. A fall in speed allows the piston valve to vent the chamber 26 through ports 34. The rotor may be retained at fine pitch by actuation of a knob 62 which has a bayonet catch (not shown) to hold the spring 43 compressed. This facilitates "jump off of the helicopter by allowing the rotor to speed up before the knob is released to allow the automatic speed control to coarsen the pitch. Fuel is fed to the rotor tip motors through passages (not shown) in the cylinder 12, servopiston 25 and a divided tube 61 in the tubular member 55.
