Title: Improvements relating to safety devices provided with cells which are sensitive to light
IPC: G08B13/184
Filed: 1924-02-19
Abstract: 230,970. Bock, E. H. Feb. 19, 1924. Light radiations, control of apparatus by.-In an alarm device in which a relay is actuated when a light sensitive cell is shaded from illumination by an electric lamp, irregularites due to fluctuations of the lamp are eliminated by the provision of an opposing circuit through the relay connected' to the source of current for the lamp. Means are also provided for counteracting the effects of variations of the daylight or other auxiliary illumination and the effects of inertia in the cell The cell 4 is disposed with its sensitive layer at the focus of a parabolic mirror 5 receiving light in a parallel beam from mirrors 3, 2, and a lamp 1, supplied with current from a source A. The circuit for the cell is branched from a coil D connected by leads B, C to the source A and extends from a tapping point 6 through leads 7, 8, the relay 9, and a measuring instrument 10 to an adjustable tapping point 11. The opposing circuit through the relay extends through a lead and an adjustable resistance 13 to a tapping point 14. One or more additional light-sensitive cells such as 24 illuminated by a lamp 25 may be arranged in series or in parallel with the cell 4. The tapping point 11 and the resistance 13 are first so adjusted that the excess of current in the opposing circuit is sufficient to cause the relay 9 to attract its armature 19 to close the circuit of the bell or other alarm 20, and the circuit is then opened at 23 whilst the adjusting lever at 11 or 13 is turned back an amount depending on the sensitiveness desired. To prevent actuation of the alarm bv an excess of current in the cell circuit, due to inertia effects in the cell or to variation of the auxiliary illumination, the relay 9 may be of the moving coil type adapted to close a circuit by movement of the coil in one direction only. A further light-sensitive cell 15 may be arranged in parallel with the resistance 13 in the opposing circuit. To frustrate an attempt to prevent operation of the device by directing a powerful light on to the cell 4, e.g. in the direction of the arrow Q, a further light-sensitive cell 17 may be arranged in front of the cell 4 for actuation of an alarm when so illuminated. This may be an independent alarm or, by arranging the cell 17 as shown in parallel with the resistance 13 the alarm 20 may be actuated through the relay 9. To effect economy in the lighting the switch 29 may be moved on to the contact 30 to enable the lamp circuits to be opened and closed periodically at the contacts 36, 28 by automatic switch mechanism. In this case inertia effects in the cell 4 may be compensated by providing in a circuit closed at the contact 36 a low-power lamp 32 arranged to illuminate the cell through an aperture 31 in the mirror 5.

Filed: 1938-02-11
Abstract: 507,947. Cigar making machines. TRIGGS, W. W. (International Cigar Machinery Co.) Feb. 11, 1938, No. 4318. [Class 130] A cigar-making machine is provided with a binder-forming mechanism and a wrapperforming mechanism, each of which includes a set of cutting devices, the devices of each set being movable in succession into leaf-receiving positions and into delivery positions, and with means for driving both mechanisms so that the cutting devices are brought in unison into the receiving and delivery positions. As shown in Fig. 1, a horizontal turret 19 carrying a pair of binder-cutting beds 20, on which tobacco leaves are held by suction, is rotated intermittently through half-revolutions to bring each bed from a position in which it receives a leaf to a position from which the cut binder is transferred by a suction carrier 23 to a rolling apron and rolled around a charge severed from a filler feeding device. The rolled bunch is transferred to a re-rolling device 25 and is carried by a transfer device 26 to one of a pair of shaping devices 29 carried by an intermittently rotated turret 27. Reciprocating cups 28 position the bunch before the jaws of the shaping device are closed. After the bunch has been shaped, a transfer device 30 delivers it to a wrapping mechanism 31 to which wrappers are fed in succession from beds 32 mounted on an intermittently rotated turret 33. To prevent overrunning of the turrets 19, 33, spring-pressed balls 76 are pressed into V-shaped slots 78 in the turrets. The binders and wrappers are cut by rollers 22, 34 which pass over the beds 20, 32 and to prevent injury to the operator's hands, vertical guards 100 are positioned above the turrets and extend across the path of the beds towards the cutting rollers. A safety lever 102 interrupts the drive of the machine if an operator reaches across the guards 100 to adjust a leaf on the bed when it is in the'cutting position. Driving gear.-The main drive shaft 40, Fig. 2, rotates shafts 43, 44 through worm-gear 41, 42. The shaft 44 actuates the filler feeding device through a chain 57 and the shaft 70 of the shaping turret 27 through a chain 61, Geneva gear 63, 67 and bevel gears 68, 69 while a cam drum 45 on the shaft 43 oscillates a segment 47 to drive through a one-way clutch 75 the shaft of the turret 19. The shaft of the turret 33 is driven through a one-way clutch 75 from a segment 51 connected to the segment 47 by a rod 50. The rollers 22, 34 are connected by a rod 94, Fig. 1, and operated in unison by a cam 80 secured to a shaft 81 driven from the shaft 43.

Title: Improvements relating to radio operated proximity sensing devices
IPC: F42C13/04
Filed: 1961-02-07
Abstract: 1,272,061. Proximity fuze. EMI Ltd. 7 Feb., 1962 [7 Feb., 1961], No. 4610/61. Heading F3A. A proximity -sensing device, which may be carried by a missile and serve to explode it, comprises an amplifier and means for transmitting a signal wave, said transmitting means being responsive to the output of the amplifier, means for receiving said signal wave after reflection from a target, means for applying said reflected wave to said amplifier, and means for detecting oscillation in said device. In the schematic circuit arrangement shown in Fig. 1, the output of an oscillator 2 is applied to a mixer stage 1 and to a modulator stage 3. A signal derived from a receiving aerial 6 is applied to the input of the mixer stage 1 and the mixer output is applied to the input of a video amplifier 4. The amplifier output is connected to the modulator stage 3 and to a trigger circuit 5. The modulator output is applied to a transmitting aerial 7. The presence of a target in the proximity of the aerials causes the transmissions from aerial 7 to be reflected back to aerial 6 and increase the coupling therebetween. This coupling between the input and output of the amplifier 4 causes it to oscillate at a frequency within its pass band, this frequency being related to the distance of the target, the oscillations being detected by the trigger circuit 5. The circuit is described in detail with reference to Fig. 2 (not shown). In a modification, (Fig. 3, not shown), a single aerial is used in conjunction with a directional coupler. In another modification (Fig. 5, not shown) the oscillator is a klystron and this is connected to a diode modulator by an isolator.
