[Also in Division G2] In a cine film or recording tape magazine, the supply and take-up spool cores 11, 14 are slidably mounted in an arcuate slot 9 in the planar base wall of the magazine whereby the cores move in the slots due to the studs 20, 21 bearing on the spool peripheries as the spool diameters change, cores 11, 14 being urged towards each other by an elastic band (23), as in Fig. 3 (not shown), passing round their bases (12, 15) which are trapped within the chamber (22) formed by hollow projection (5). The film 10 leaves slit 7 and returns through slit 8. Core bases (12, 15) enter chamber (22) through enlarged opening 9<SP>1</SP>, Fig. 2, in slot 9, and their undersides have apertures (13, 16), Fig. 3, which are engaged through a slit (10) in base (6) by driving spindles. Driving mechanism.-Supply and take-up spindles (45, 46), Fig. 6 (not shown), slide in a slot (42) in the mechanism housing aligned with slots 9 and 10. On spindle (45) is freely mounted a pulley (47) which is pressed upwardly by a spring to bear against a friction ring on the underside of a disc (48) fixed on spindle (45), thereby forming a friction clutch. A similar clutch system is carried on spindle (46), comprising pulley (51) and disc (52). Pulleys (47), (51) are driven through elastic belts (55), (56) by pulleys (30) and (28) on a spindle at the centre of the arc of slot 42 and driven further belt (57) over pulley (27) and a small pulley (35) fixed to spindle (31). Forward film feed is provided by moving idle wheel (38) on pivoting arm (40) to contact motor shaft (37) and a large friction wheel (34) on shaft (31), the spindles and cores moving along their slots as the spool diameters change. Rewind is initiated by contacting shaft (37) and friction wheel (29). In another form, the arcuate slots have less curvature and drive belts are tensioned by spring-loaded rollers.

Title: Stabilisation of vinyl phenols and ethers thereof
IPC: C07C37/88
Filed: 1948-11-24
Abstract: Vinylphenol, a vinylphenol ether, or a lower nuclear homologue thereof is stabilized by the addition of at least 0.01 per cent weight of ammonia, hydrazine or a substituted hydrazine, an aliphatic or aromatic amine, a saturated or unsaturated heterocyclic amine, or a hydroxyl derivative of any of the said amines.  The expression substituted hydrazine means compounds based on hydrazine in which one or more hydrogen atoms have been replaced by an alkyl, aryl, or aralkyl group and the hydroxy derivatives of such compounds in which the hydroxyl group is not attached directly to a nitrogen atom of the hydrazine residue. Examples of suitable stabilizers include trimethylamine, aniline, p-aminophenol, b -phenylnaphthylamine, pyridine, quinoline, 8-hydroxyquinoline, piperidine, phenylhydrazine, o- and p-phenylenediamine, and metol; salts of the amines may be used when they are sufficiently soluble.

Title: Tuner unit
Inventor: JONES JAMES DOUGLAS
IPC: H03D9/06
Filed: 1962-08-11
Abstract: 967,018. Radio receiving circuits. PYE Ltd. Aug. 8, 1963 [Aug. 11, 1962], No. 30875/62. Heading H3Q. A tuner operating over both V.H.F. and U.H.F. bands-as shown comprising a groundedgrid R.F. stage V1 coupled by means of a tuned bandpass filter to a mixer/oscillator V2-is tuned by means of ganged variable capacitors C1-C4, in conjunction with half-wave lines L2, L3, L4, L6 respectively and trimmer capacitors T1-T8 on the U.H.F. band. In accordance with the invention the coils L8- L9 and 10-15 used on the V.H.F. bands are switched across the trimmer capacitors TC1, TC3, TC5, TC7 at the ends of the lines L2, L3, L4, L6 remote from the ganged variable capacitors C1-C4. In this way these coils are introduced at points which constitute voltage nodes at U.H.F. and so the stray capacitances associated with the switching circuits cause a minimum disturbance of the tuning on the U.H.F. band. The V.H.F. switching is arranged so that in the aerial circuit different coils, e.g. L8, L9 are alternatively switched into circuit for different frequency ranges. In the other circuits the coils for the higher frequencies, e.g. L14, are switched in parallel with the coils, e.g. L15 for the lower frequencies, the switching in each case being by means of a slide switch. To avoid interference from U.H.F. stations when operating on V.H.F., the line L3 is detuned by means of a conductor D.C. which is moved into close proximity to it upon operation of the slide switch. A.G.C. may be applied to the R.F. stage V1 and the arrangement may alternatively be modified so as to use transistors (Fig. 2, not shown).
