Title: Improvements relating to cinematograph apparatus
IPC: G03B21/46
Filed: 1948-01-26
Abstract: 639,753. Kinematograph projectors. RUDD, W. T. Jan. 26, 1948, No. 2336. [Class 97 (i)] The projection lens is mounted on a support capable of movement transverse to the axis of the optical system in the direction of film feed and a. member, of the film gate provided.with a mask aperture is mounted, on a pivot connected to the lens support but free to, yield away, from the fixed, member of the film, gate against resilient bias so that the pivoted member may rock about its pivot and yield at one point of its length while remaining, pressed against, the fixed member over part of the remainder of its length, and at the same time, as the mask is adjusted to frame the picture the lens is moved with it so. as to maintain the correct relative positions of the mask and.lens. In,the form shown, the lens 19 is secured to a slide member 15 which can move in a slide-way 16, with bridge-pieces 18, secured to a.mounting plate by screws 17 round which are compression springs (not shown) which press the slide member up into frictional contact with the bridgepieces. The screws 17 pass through elongated holes in the slide member to permit the latter to move. A downward. extension 15a of the slide member carries a pivot for a bell-crank 8. The arm 8b has a notch in which engages a pin 10 carried on a member 11 projecting from the curved gate member 6 with masking aperture 22. A leaf-spring 7 is secured to the bell-crank at 9 and the upper part holds the pin in its notch. The lower part is secured to a pin 14 and urges the bell-crank about its pivot to exert pressure on the gate member 6. This pressure can be released for film threading by pressure on the bell-crank arm 8a. The fixed gate member 1 has a longer aperture 23 than the corresponding aperture 22 in the member 6, which latter has a longer aperture 25, for the passage of the feed claw, than that in the member 1.

Title: Improvements in and relating to tone control systems
IPC: H03G5/06
Filed: 1943-02-12
Abstract: 568,672. Tone-adjusting networks. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 12, 1943, No. 2337. Convention date, 'Feb. 19, 1942. [Class 40 (iii)] In a tone-adjusting system, a volume-controlling potentiometer 7, Fig. 1, is by-passed. for high-frequencies via condenser 15 and resistance 14 to an extent which depends on the position of the tapping point 18 on a resistance 16. When the point 18 is at the top, the high-frequencies are emphasized. When it is at the bottom, they are suppressed, since the condenser 17 virtually short-circuits the source at frequencies above, say, 4000 cycles. Resistance 14, which may be omitted, limits the maximum extent to which the highfrequencies can be emphasized. The potentiometer 7 also varies the frequency response, since, when its slider is at the top, the increase of high-frequency response due to the circuit 16, 15, 14 is zero, a gradual increase in this effect taking place as the slider is lowered. The reduction of high-frequencies when slider 18 is low on resistance 16 is independent of the potentiometer setting. In a modification, Fig. 3, the condenser 15 is permanently connected to an intermediate point of the potentiometer resistance instead of to the slider and an additional condenser/resistance circuit 22, 23 is provided to by-pass the higher-frequencies and so emphasize those below, say, 400 cycles.

Filed: 1953-01-29
Abstract: 724,994. Extruding. COMPTOIR INDUS. TRIEL D'ETIRAGE ET PROFILAGE DE METAUX. Jan. 29, 1953 [March 20, 1952], No. 2611/53. Class 83 (4). A device for feeding billets to an extrusion press comprises a carriage 11 movable perpendicularly to the axis of the press and having pivoted thereto a table 13 provided in its edge adjacent the press with a channel 18 for retaining the billet 23, means 15 being provided for holding the table so that the billet is aligned with the bore 20 of the container and for releasing the table when the billet has been pressed into the container by the press ram. The carriage is suspended from rollers 9 running along rails 8. The table is preferably formed in longitudinally-spaced halves both of which are pivoted independently of each other on an axle 12 and are engaged by separate hooks 15 pivoted on pins 16. These hooks retain the table with a slight downward slope towards the channel 18. When the carriage has been moved to its extreme righthand position a heated billet is placed on the table which has been previously covered with a sheet of lubricant such as glass fibres. The billet rolls down the table and after being wrapped in the sheet of glass fibres falls into the channel 18. The carriage is then moved inwardly until the billet is coaxial with the container bore. A cam member 21 connected to move longitudinally with the ram, engages the tail pieces 17 of the hooks 15 and thus releases the half-tables in succession which fall against a ramp 22 and out of the path of the ram. The carriage may then be withdrawn, whereby the half-tables are raised by the ramp and are re-engaged by the hooks.

Filed: 1967-01-18
Abstract: 1,174,621. Protective arrangements. ROBERT BOSCH G.m.b.H. 18 Jan., 1967 [19 Jan., 1966], No. 2655/67. Heading H2K. [Also in Division G3] An electrical supply system, e.g. for a motor vehicle, comprises a generator 10 connected to a battery 15 by way of a rectifier 12 and output leads 13, 14; a voltage regulator 16 including a switching transistor 18 which is connected together with a fuse 23 in series with the generator field winding 24 and which is controlled by way of a further transistor 19, in dependence upon output voltage variations as detected by a sensing circuit 35-39; and a protective circuit 17 including a relay coil 27 which is connected across the output leads 13, 14 in series with the collector-emitter path of a transistor 43, the normally open contacts 26 of the relay being connected in parallel with the field winding 24 and the base of the transistor 43 being connected over a Zener diode 45 to a voltage divider 50, 51, 52 also connected across the output leads 13, 14. In normal operation the arrangement is such that relay 27 is not energized, and the output voltage is maintained constant at a predetermined value by the action of regulator 16 in known manner. However, should an excessive voltage, e.g. 105-110% of predetermined rated output voltage, arise on the leads 13, 14, for example because of a collector to emitter short-circuit in the transistor 18 of regulator 16, the Zener diode 45 conducts to render transistor 43 conductive, thereby energizing relay coil 27 so that contacts 26 close; the current flowing through transistor 18 then rises momentarily to a value above the rating of fuse 23 which thus burns out, whereby the excitation current drops to zero and the generator 10 runs without load. A temperature dependent resistor may replace the transistor 43.
