Title: Improvements in flash light lamps
IPC: F21K5/08
Filed: 1936-08-19
Abstract: 465,021. Flash-light lamps. DOERING, U. W. Aug. 19, 1936, No. 22844. [Class 9 (ii)] Relates to a flash-light lamp in which the flash is produced by the combustion of metal powder in a closed container containing active gas and ignited by an explosive primer and consists in disposing the explosive primer beneath or within the metal powder so as to atomize the latter throughout the enclosed volume of active gas creating a mixture of gas and powder particles which is ignited substantially instantaneously. Fig. 1 shows a construction employing a glass bulb 1 filled with an active gas, such as oxygen, chlorine or nitrous oxide, and sealed by a cap 2 joined to which is a cartridge-like container 5 containing the explosive charge 6 and flash-light material 8. A cover 9 of asbestos or aluminium foil seals the container at the top. If desired, an additional device 10, e.g. a grid, net or an impinging surface in the form of an inclined mica plate, may be provided to facilitate the atomization of the metal powder. The charge 6 is ignited from the outside by the impact of a pin or bolt. If it is desired to dispense with the pipe 3 a metal pumping nipple 4 sealed by pressing together or cementing may be provided. Fig. 2 shows a modification in which the charge 6 having an electrical ignition wire 13 embedded therein is disposed in the centre of a pellet of metal powder 8 . surrounded by a metal net 14. The metal powder may consist of aluminium, zirconium, strontium, calcium or lithium or mixtures, alloys or compounds of these metals. Such metals may be mixed with or added to powders of aluminium, magnesium, cerium or strontium hydride.

Title: Method of producing carbon dollies for dry cells and apparatus therefor
IPC: H01M4/10
Filed: 1931-08-13
Abstract: 377,823. Moulding dollies for dry batteries. BUMKE GES., H. A., 8, Chausseestrasse, and AUTOM - SPEZIAL - MASCHINEN GES., 5, B³lowstrasse, both in Berlin. Aug. 13, 1931, No. 22916. Convention date, Jan. 21. [Class 87 (ii).] In the preparation of carbon dollies for dry cells, the depolarizing composition is caused to rotate on its axis during the final pressing and while the carbon rod is inserted. Preferably this is effected by causing the finishing mould to rotate on its axis. In the operation of the apparatus shown in the drawing, the depolarizing composition is taken from the supply vessel and conveyed to and deposited in the shaping mould 1. When the vertical punches 13 have moved to their lowermost position, the horizontally disposed punches 3 move up against the finishing mould 2 which is rotating ; the carbon rods are fed and forced in by the piston 16, while the composition is subjected to continuous pressure.

Title: Electric shutter for photographic devices
IPC: G03B9/58
Filed: 1967-05-17
Abstract: 1,185,215. Electrical exposure control. RICOH K.K. May 17, 1967 [July 15, 1966], No.22991/67. Heading G2A. An electrical circuit for automatically controlling the exposure time of a photographic shutter comprises a photo-resistor cell 7, in series with which is a heating resistor such as the filament of a midget lamp 10. When a photograph is to be taken, actuation of the shutter release closes a switch 2, which completes a circuit from battery 1 through cell 7 and lamp 10, and also causes an electromagnet 3 to be energized. The shutter remains open as long as the electromagnet is energized. As switch 2 closes, a contact 12 is broken, and current flows through cell 7 and lamp 10, heating the latter and increasing its resistance. Thus the potential difference between points a and b increases until a condition is reached when transistor 6 is rendered conducting and transistor 4 non-conducting, thus de-energizing the electromagnet 3 and so closing the shutter. Since the current through the lamp 10 is determined by the resistance of the photo-element 7, which in turn depends on the incident illumination, the exposure period is determined by this latter. Before an exposure is made, the adequacy of the incident light may be tested by closing a switch 14 (which also opens a contact 13). Current from battery 1 now flows through cell 7 and lamp 10, and the time taken for the filament of lamp 10 to be heated sufficiently to light up is an indication of the illumination falling on cell 7. If lamp 10 (which may be visible in the view-finder field) does not light up at all, then the illumination is insufficient.

Abstract: 1,201,748. Glove boxes. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 May, 1969 [17 May, 1968], No. 23097/69. Heading B4Q. A glove box 1, which may be surrounded by shielding 3, has a transfer chamber 9 sealed at its two ends by doors 12, 13. Scavenging air is drawn through the glove box by suction applied at a pipe 26 whereby the interior 2 of the glove box is maintained at sub-atmospheric pressure. The air is taken in at a filter 17 and flows in a circuit comprising pipe 19, chamber 9, pipe 22, filter 18, the interior 2, filter 23, pipe 24, filter 25 and the pipe 26. A baffle 20 directs the air against the inner surface of door 13 to clean its surface When door 12 is opened the air flows directly into the interior 2 and by-passes the filter 18, the reduced resistance to flow causing an increase in the flow rate. Similarly, when door 13 is opened the air flows directly into the chamber 9 and by-passes the filter 17 to increase the flow rate.

Title: Improvements in or relating to clutches
IPC: F16D11/10
Filed: 1953-08-24
Abstract: 744,943. Positive clutches. HARVEY, Ltd.. W., and HARVEY, J. W. Oct. 11, 1954 [Aug, 24, 1953], No. 23288/53. Class 80(2) A positive clutch comprises a disc 1 in which is a groove 3 extending round a circle having an axis eccentric to the main axis of the Clutch, and a disc 2 having a corresponding eccentric ridge 4 to engage in the groove when the discs are moved together. The single groove and ridge 3, 4 shown can be replaced by sets of grooves and of ridges each on circles having the same centre arranged eccentrically with respect to the main clutch axis. Alternatively, the groove and ridge 3, 4 can be interrupted instead of continuous, or the groove can be continuous and the ridge interrupted, &c. The disc 1 is keyed to a sleeve 7 in turn secured to a driving 'shaft 5. The disc 2 is fast on a carrier disc 11 axially slidable on but rotating with a driven shaft 10. The sleeve 7 on the driving shaf t5 extends round and centres the driven shaft 10 by means of a bearing 18. A flange 9 on the sleeve 7 has holes receiving sliding bolts 23 which extend therethrough and carry at their ends a cone shaped friction clutch member 20. The clutch member 20 is biased to the right of the Figure, to engage with a corresponding conical friction surface 19 in the driven disc 2, by light springs 21. Heavy springs 14 between a disc 15 fast on the driven shaft 10 and the driven disc 2, &c., bias the latter to the left of the Figure to engage the clutch; the clutch is held in the disengaged position shown by a member having a running engagement with a groove 17 in the disc 11 and .operated by external linkwork (not described). In the disengaged position, the friction cone 20 is just free of the coned surface 19 on the driven disc 2. To engage the clutch, the external linkwork is operated to allow the springs 14 to move the disc 2, &c., to the left. This first engages the friction clutch 19, 20 to effect synchronization of the driving and driven discs. The springs 14 being stronger than the springs 21, the latter are then overcome and, when the positions of the groove 3 and ridge 4 coincide, positive engagement is effected.

Title: Improvements in remote control and protection of electric motors
IPC: H02H7/00
Filed: 1950-09-23
Abstract: 681,232. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. Sept. 23, 1950, No. 23366/50. Addition to 665,571. Class 38(v) coil of a relay, is modified by the provision of a secondary winding on tne transductor to supply the opening coil of the relay or of a further relay. In Fig. 1, the closing coil H<SP>1</SP> of the relay H is supplied from a full-wave rectifier F connected in series with the A.C. exciting winding Y<SP>1</SP>, Y<SP>2</SP> of the transductor and a source of supply G<SP>2</SP>. The opening coil H<SP>2</SP> is supplied from a full-wave rectifier F<SP>1</SP> supplied from the secondary winding G<SP>5</SP> of the transductor. The D.C. control winding Y<SP>3</SP> is connected in series with the rectifier N and control switch K and supplied from a secondary winding G4 on the transductor or from a separate "step-down" transformer. When the switch is in the "ofF" position K<SP>1</SP>, the D.C. control winding Y<SP>3</SP> is not energised so that the transductor Y acts as a simple transformer and the relay coil H<SP>2</SP> is fully energised, whereas due to the high impedance of the windings Y<SP>1</SP>, Y<SP>2</SP>, the relay coil H<SP>1</SP> is substantially de-energised. The relay contacts 14 are thus held open by the coil H<SP>2</SP>. When the switch K is moved to the start position K<SP>2</SP>, the D.C. control winding Y<SP>3</SP> is fully energised. The resulting saturation of the transductor core reduces the impedance of the windings Y<SP>1</SP> Y<SP>2</SP> so that the relay coil H<SP>1</SP> is fully energised. This is accompanied by a substantial loss of voltage across the secondary winding G<SP>5</SP> so that the relay coil H<SP>2</SP> is substantially de-energised. The relay H closes its contacts 14 to energise the closing coil of the contactor C to start the motor M. When the switch K moves into, or is moved into, the "running" position K<SP>3</SP>, the effect of the control winding Y<SP>3</SP> is reduced to a level such that the relay H remains closed, but if opened due to a no-volt or fault condition and the switch K is left in position K', the restoration of normal conditions does not automatically reclose the relay. In. Fig. 2 separate "closing" and opening relays H<SP>1</SP>, H<SP>2</SP> are provided, the relay H<SP>1</SP> having normally-open contacts which are closed to start the motor and the relay H<SP>2</SP> having normally-closed contacts which are opened to stop the motor. As an alternative to the full-wave rectifiers F, F<SP>1</SP>, half-wave rectifiers and smoothing condensers may be used, Fig. 3 (not shown). It is stated that though the saturation of the reactor reduces the voltage induced in the secondary winding G<SP>4</SP> for supplying the D.C. control winding, the latter winding is sufficiently energised to provide ample saturation for the system to function as described above.
