Patent GB-1051016-A (GB)
Abstract: 1,051,016. Transistor amplifying circuits; radio receiving arrangements. ANTIFERENCE Ltd. Sept. 23, 1965 [Sept. 29, 1964], No. 39617/64. Headings H3Q and H3T. The invention relates to an ultra-high frequency amplifier comprising a transistor in common base connection, and is more particularly intended for a mast-head pro-amplifier in which the emitter is fed from an aerial via input capacitor 11 and the output signal is taken through an output capacitor 12 from a tapping on a coil 13 which constitutes the collector load. Instability is liable to occur in such arrangements due to feedback via capacitance coupling through the transistor: according to the invention this is prevented by providing the input circuit with an inductive reactance at operating frequencies. In the embodiment this comprises a section of shortcircuited transmission line 14 which is less than a quarter wavelength long at these frequencies. The arrangement also prevents cross-modulation with V.H.F. signals, since for such frequencies the line 14 constitutes a short-circuit: it also minimizes the risk of transistor breakdown due to high voltage pulses occurring during thunderstorms.

Abstract: 1,054,308. Container closures. LE BOUCHAGE MECANIQUE. June 12, 1964 [June 12, 1963], No. 24518/64. Heading B8T. A tamper-proof, screw-cap closure, made of yielding plastics material, comprises an upper internally threaded cap part 1, Fig. 1 (not shown), and a lower ring 2 interconnected by a weakened frangible portion 11 and is fitted on a, bottle &c. neck 3, the bottom of which has a shoulder 4. The lower ring 2 of the cap has four pawls, 9 Fig. 3 (not shown), moulded thereon so as to lie obliquely to its wall and preferably arranged in diametrically opposite pairs. The top edges of the pawls 9 are joined to the upper part 1 of the cap by being bridged over with material 11 giving the frangible portion. The collar 13 of the bottle &c. neck, which engages the lower ring 2 of the cap, is shaped as two half-cylinders interconnected by two stop faces which serve as catches for the pawls 9 and prevent the unscrewing of the ring. The upper threaded cap part 1 can thus be unscrewed on the rupturing of the fragile portion 11.

Abstract: 1,227,372. Metal powder press. MANNESMANN - MEER A.G. 1 July, 1968 [5 July, 1967], No. 31268/68. Heading B5A. [Also in Divisions B4-B5] In a metal powder compression moulding press, a fixed lower die 37 and a displaceable upper die 14 co-operate with a matrix 1 which is simultaneously downwardly displaceable by a mechanism which is actuated from the compression movement of the upper die 14, and is adjustable in a continuously variable manner to vary the speed of the downward displacement of the matrix 1. The downward displacement of the matrix 1 is effected by a bar 15 which is connected to move with the upper die 14 and abuts blocks 16 at the end of a rocking lever 6, which is pivoted at 7 to the press framework and is connected by a link 3 to the die 14. The link 3 is pivotally attached to the lever 6 at a member 8 which is adjustably displaceable along the lever 6, to vary the speed of descent of the die 14, via a spindle 9, gears 13, splined sleeve and shaft 12, 11, and gears 10. The length of the link 3 is adjustable to vary the point at which the bar 15 engages the blocks 16, via a turnbuckle 17, driven by gears 20 and splined sleeve and shaft 19, 18. The extent of descent of the matrix 1 is limited by the abutment of the lever 16 against a stop 21 which is linearly reciprocable into and out of the stopping position by a cam 26, acting via a compression spring 27 loaded link 22 and lever 24 connection. Upward movement of the matrix 1 with the plunger 14 is prevented by an arcuately reciprocated catch 30, actuated also by the cam 26, via a tension spring 35 loaded bell crank lever 32 and link 36 connection. After the die 14 has been raised, the stop 21 is retracted by the cam 26, and the die 14 is lowered for ejection of the moulded article (by lower ram 37) by a cam 26a acting on the rod 2, via a compression spring 40 urged linked lever arrangement 38, 39, the cam 26 then permitting arcuate displacement of the catch 30 from the path of the lever 6, as the cam 26a permits the upward return of the matrix 14 by the action of the compression spring 40 in the lever 39.

Abstract: 1,229,757. Ink ribbon mechanisms. HONEYWELL Inc. 28 May, 1969 [31 May, 1968], No. 27002/69. Heading B6F. [Also in Divisions F2, G1 and H3] A carriage 266 for the printing ribbon 245 of a multi-channel chart recorder comprises a U- shaped frame 267 forming guide surfaces 275L and 275R for the ribbon as it passes between print elements 239, 242 and a recording chart (not shown). The element 239 prints a trace of an input variable whilst the element 242 has numerals 246 on its circular periphery and prints a number corresponding to each trace. Spools 271L, 271R are provided for the ribbon and have flanged ends provided with ratchet teeth 272L, 272R. Bell-cranks 273L, 273R having pawls 274L, 274R biased by springs 279L, 279R are pivotally mounted on a front portion 267F of the frame. A pair of rocker arms 280, 281 forming a toggle pivoted about a point 282 are provided with an overcentre spring 283. The ends of the rocker arm 281 carry detents 284L, 284R and projections 277L, 277R which are adapted to raise the pawls 274L, 274R. The ends of the rocker arm 280 carry feelers 278L, 278R which sense the amount of ribbon on each spool. The carriage 266 is pivotally mounted on bosses 268L, 268R so that it may be tilted to bring a different transverse portion of the ribbon below the printing elements. The ribbon is divided across its width into six longitudinal bands, each impregnated with a differently coloured ink and the carriage is tilted in a cycle of six steps before being returned to its initial position. The tilting of the frame 267 causes a bell-crank 285 to actuate the bell-cranks 273, thus moving the pawls 274, the ribbon being advanced longitudinally once for each cycle of six tilting steps of the ribbon. As shown, the pawl 274L indexes the spool 271L, thus winding the ribbon on this spool until the movement of the feeler 278L causes the rockers 280, 281 to overcentre, the projection 277L thus lifting the pawl 274L out of engagement with the teeth 272L. At the same time, this movement of the rockers causes the pawl 274R to engage the teeth 272R and winding of the ribbon 245 on to the spool 271R commences.
