Title: Cine cameras
IPC: G03B1/60
Filed: 1975-08-29
Abstract: 1521288 Cinematograph film metering AGFA GEVAERT A G 29 Aug 1975 [30 Aug 1974] 35708/75 Heading G2E A cinematograph camera includes means for generating pulses in synchronism with film advancement, a counter for receiving the pulses, and indicators responsive to the counter, wherein each indicator responds when its particular count is reached, thereby indicating the number of frames run through. As shown, a cam 3, rotating with a shutter 1, operates a switch 5, 6 to produce at least one pulse per frame. After passing NAND gates 7, 8, which eliminate spurious pulses, the pulses are fed to binary-decimal counters Z1, Z2, Z3, Z4. Since the counts used are always over 100, the outputs of counters Z3, Z4 only are connected to logic circuits 9-14. Each logic circuit comprises two AND gates and a NAND gate, and is responsive to a particular count which increases along the logic circuits. Thus, when the count reaches, say, 600 (i.e. 600 frames have been exposed) logic circuit 9 emits a pulse which operates a JK flip-flop 33, which in turn causes a LED 48 to glow. Subsequent operations cause LED's 49-53 to glow in turn as counts of (say) 1200, 1800, 2400, 3000 and 3600 are reached. Where the count 3600 is reached, the shutter drive motor is switched off. The LED's may be visible in the view-finder and/or elsewhere. A switch 46, which closes when the camera lid is closed, connects the current supply to the counters. When the camera lid is opened switch 46 opens and this resets the counters Z1- Z4 and the flip-flops. An LED 47 is caused to glow when a switch 54 is closed by the insertion of a cassette.

Title: Improvements in or relating to current and/or voltage value indicating apparatus
IPC: G11B7/00
Filed: 1938-12-16
Abstract: 511,263. Current and voltage measurements. KLANGFILM GES. Dec. 16, 1938, No. 36700. Convention date, Dec. 31, 1937. [Class 37] Average and peak values of currents or voltages, especially in respect of sound film values, are indicated by causing a band of light to be controlled as regards its height and width by known measuring apparatus responsive to the values in question. A shutter 5 moved in the directions of arrows A by a peak value meter varies the height of a light band passing slot 6 and falling on mirror 3. The mirror is rotated in the direction of arrows C by an average value meter, so that the height and width of the image on scale-plate 4 gives a direct indication of the values desired. A further shutter 5 can be employed, in which case peak values above and below the x axis are indicated. In another arrangement, a colour wedge is moved across the slot 6 by the peak value meter so that alterations in the values are indicated as colour changes. Alternatively a screen having a stepped aperture can be moved across the slot 6. The slotted plate 2 and shutters 5, 5<1> can be located between the mirror and scale-plate.

Title: Constant energy pulse generator
IPC: H03K3/015
Filed: 1973-08-02
Abstract: 1445426 Pulse generators WILSON GREATBATCH Ltd 2 Aug 1973 [9 Aug 1972] 36759/73 Heading H3T [Also in Division A5] A pulse generator comprises an oscillator providing output pulses, the pulse voltage being proportional to the supply battery voltage and a timer connected to the oscillator to variably control the pulse duration, the control responding to changes in battery voltage so that the duration of the pulse is changed to maintain the pulse energy constant. The pulse generator, which is incorporated in a heart pacemaker to supply stimulating pulses via terminals 71, 72, Fig. 2, comprises a complementary pair of transistors 84, 90, connected as shown, with a condenser 108 chargeable through a resistor 95. Capacitor 108 charges via resistor 95 until the voltage across it exceeds the base-emitter threshold of transistor 84, whereupon transistors 84 and 90 conduct. Both sides of capacitor 108 rise in voltage by the battery voltage, i.e. about three volts. Since transistor 90 is conducting, and its collector is connected via resistor 120 to the base of transistor 115, this transistor 115 conducts to allow capacitor 108 to discharge through a resistor 124 and a diode 122. If the battery voltage is high, it can break down a series of Zener diodes 134 and current flows in a circuit including transistor 90 (when conducting) resistor 138, Zener diodes 134, and resistor 137, switching on transistor 126, so that capacitor 108 is discharged additionally through a resistor 132 ,130 and a short pulse is produced. When the battery voltage is reduced below a given value, the Zener diodes do not break down and there is discharge only through resistor 124. The pulse is therefore lengthened to compensate for decreased pulse power due to battery voltage drop. A test switch 142 (which may be an implanted reed switch) is closed for test pulses. If the battery voltage is high, the Zener diodes will be conducting, and closing the switch will make no difference. However, if the Zener diodes are not conducting, closure of the switch will cause a change to narrow pulses. In consequence the patient's heart beat will not follow the pulses, and this indicates that the battery is running down.

The metal salts of the complex may be salts of calcium, barium, strontium or magnesium.  The inorganic salts of the complex may be sulphates and/or nitrates, or mixtures of sulphates and phosphates.  The complex forms when the mixture of metal salts (or metal base plus mixed acids) is heated to at least 400 DEG  F.  The complex may be formed in the presence of the lubricating oil.  The lubricating composition may also contain oxidation inhibitors, metal deactivators or corrosion preventatives. Lubricating compositions of the invention have anti-wear and extreme pressure properties and, when they contain larger proportions (e.g. 15-40 per cent by weight) of the complex, are greases.  In the examples, mineral lubricating oil compositions are described which contain a complex derived from calcium acetate, calcium salt of a polypropyl benzene sulphonic acid and calcium sulphate, nitrate or phosphate (or sulphate plus phosphate).  In some cases, phenyl alpha naphthylamine or calcium soap of hydrogenated fish oil acids is also present.
