Title: Automatic fire extinguishing water sprinkler and alarm
IPC: A62C35/60
Filed: 1920-05-26
Abstract: 152,938. Eastman, H. May 26, 1920. Alarms operated by fusible devices. - A fusible sprinkler head adapted also to give an electric alarm when operated by the heat of a fire comprises a frame 1 provided with a sliding valve stem 7 fitted with a sleeve 8 having a slitted cup 9 to support a ball-valve 6, which is held against its seat 5 by the engagement of the lower end 13 of the stem 7 with a plate 20 having a lug 22 soldered at 23 to the lug 21 on a bracket 33, which is attached to the lower part 11 of the frame 1 by screws 15. When the solder at 23 is melted, the plate 20 is released from the bracket 33 and the stem 7 descends under the pressure of the water and of the spring 12, thus releasing the valve 6, the cup 9 acting as a spreader for the issuing water. A key 32 prevents rotation of the stem 7. An electric contact 25 fixed to the stem 7, or to a collar carried thereby, also engages an insulated contact 26 to close an alarm circuit.

Abstract: 1,098,184. Registration marks on film. SIDNEY R. LITTLEJOHN & CO. Ltd. April 23, 1965 [April 7, 1964], No. 14360/64. Heading G2A. A film L is located on a work-table C, the table having a pair of exposure housings Q slidably mounted above it so as to photo-print register markings on the edge of the film. The housings are mounted to slide along parallel shafts H, which shafts themselves can slide in a further direction at right angles. Screws are provided for locking the slides in any desired position. Fig. 2 (not shown) is a more detailed view of the housing (Q), showing how light from a lamp (AK) passes down a tube (T). At the bottom of the tube (T) is mounted a rotatable ring (AB), to the underside of which is fixed a graticule (AG) carrying negative and positive marks (AI) and (AJ) Fig. 3 (not shown). The ring is eccentrically mounted, so that it can be rotated to bring either mark on to the exposure axis (AH). Each housing has a handle AF by means of which it can be rotated on shaft H so that it is out of contact with film D (right hand side of Fig. 1) while the normal exposure is made. It is then rotated so as to be in contact with the film (left hand side of Fig. 1) for exposure to the registration mark. Such marks are useful for accurate registration of a plurality of films, as for example in colour printing.

Abstract: 568,430. Charging batteries. STANDARD TELEPHONES & CABLES, Ltd. Sept. 3, 1943, No. 14412. Convention date, Dec. 5, 1942. [Class 38 (iv)] Batteries of different voltage are connected to a charging circuit which has voltage adjusting means automatically operated by means selectively controlled by the battery volts. A charging circuit 32, 34 is energized from A.C. mains 1-3 through a three-phase transformer and rectifier 25, a tap changing relay 12 controlling the connection of different tappings of the transformer primary windings 9-11 to the mains to provide in the charging circuit voltages suitable for either a 6-volt or 12-volt battery. The tap-changing relay is controlled by a marginal relay 38 set to operate at about 9 volts and connected across the charging terminals 33, 37 of the charging circuit. The marginal relay is thus only actuated by connection of a 12-volt battery to the charging terminals, this relay then energizing relay 12 to increase the transformation ratio. The tapchanging relay may operate on the secondary instead of the primary of the transformer and a number of such relays and marginal relays may be employed when more than two battery voltages are involved.

Title: Ionizing radiation detector
IPC: G01T1/14
Filed: 1951-06-19
Abstract: 698,980. Condenser arrangements. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 19, 1951 [June 27, 1950], No. 14558/51. Class 38 (iv). [Also in Group XL (b)] The high voltage necessary for a radiation detector such as a Geiger tube is derived from a condenser charged to a high voltage. As shown, a high voltage derived from a magneto is applied to housing terminals 10 of a transformer 4, the condenser 5 being charged from the secondary through a rectifying tube 7. During the charge a gas-discharge tube fires when the voltage across the transformer secondary rises above 70; the voltage across the tube then falls back to 60 volts. Almost the whole of the transformer secondary voltage is then across condenser 2. The condenser and transformer together form a circuit which is resonant at a little under alternator frequency. Ionization of the Geiger tube develops a pulse across the transformer 4 which acts as a matching impedance for the headphones. The charges on the system are then equalized by a resistor 6 whose impedance is high in comparison with series condenser 3, 2 and transformer 4. To prevent over-voltage on the Geiger tube, condenser 9 and resistor 6 constitute a circuit having a time constant five times smaller than that of the rejector comprising condenser 2 and transformer 4. During discharge, ionization of the Geiger tube develops a pulse across the transformer through condensers 2, 9. Transformer 4 thus acts as a headphonematching impedance. Resistor 6 maintains the direct voltage on the Geiger tube. The whole instrument may be enclosed in a casing filled with nitrogen S at a pressure of 5 kilograms/cm.<SP>2</SP>

Grinding-apparatus comprises a ram or ball which is loosely disposed in a vessel the crosssection of which is reduced towards an outlet opening in the bottom of the vessel, the shape of the ram or ball relatively to that of the vessel being such that between the ram or ball and the inner surface of the vessel a space is formed which decreases continuously towards the outlet opening, vibrating means acting directly on the vessel or on the ram or ball. In the form shown, the vessel 1 is fixed to a table 7 which is supported on a fixed table by means of springs 8, the table 7 having fixed thereto an eccentric 9 which when rotated causes the vessel and ball 2 to vibrate. The vibrations may, however, be caused by one or more shakers or by electric means. The stem 4 of the ball is guided in a bridge-piece 5. The ram may be in the form of an ellipsoid, the inner surface of the vessel being correspondingly shaped. Instead of the vessel being vibrated, a vibrator may be supported in the interior of a hollow ram. A number of vibrators may be used.

Abstract: 1,214,833. Aerials; Doppler radar; semiconductor oscillators. NATIONAL RESEARCH DEVELOPMENT CORP. 29 March, 1968 [31 March, 1967], No. 14839/67. Headings H3T, H4A and H4D. A radar apparatus comprises a gallium arsenide diode 11, Fig. 1, which operates as a Gunn effect oscillator and is mounted in a resonant cavity formed by apertures 13, 19 in blocks 15, 17 and terminated by a shortcircuiting plate 21. The upper end of the diode 11 is connected to the block 15 by a post 39 and its lower end rests on a conductor 41, which is insulated from the block 15 by a thin layer 43, so constituting a by-pass capacitor. The conductor 41 extends transversely to the centre member of a coaxial socket, by means of which direct current is supplied to the diode 11 (Fig. 2, not shown). The aperture 13 in the block 15 is extended by apertures 25, 33 in blocks 23, 31. The aperture 25 acts as a matching section and adjusting screws 27, 29 extend therein. The aperture 33 contains a mixer diode 35 which is connected on one side to the block 31 and on the other side to an output connector 37. The assembly is completed by an electromagnetic horn which is bolted on the outer face of the block 31 and which is coupled to the aperture 33 (Fig. 3, not shown). In operation, the diode 35 receives part of the energy emitted from the oscillating diode 11, and also energy returned by a reflecting target. If the target has radial motion, there will be a difference in frequency because of the Doppler effect, and the diode 35 will provide an output at the said difference frequency. A collar of ferrite material may surround the diode 11, when variation of the voltage applied to the diode 11 will result in change of the oscillation frequency thereof, so that the radar apparatus may be used in a frequency modulation mode. In one application, triangular pieces M, Fig. 5, of a reflective material are applied to the surface of a road, and a radar of the kind described is carried on a vehicle and directed at the road. As the Doppler frequency is proportional to the velocity of the vehicle, and the time of dwell of the radar beam upon a given width of reflective material is inversely proportional to the velocity of the vehicle, the number of cycles of Doppler frequency is proportional to the said width. In this way, the distance of the vehicle from the side of the road may be determined, and control means may be provided to guide the vehicle so that that distance is made to have a desired value.
